The small retractable protective plate solves the falling risk of workers working at heights; The forklift is equipped with laser radar, and automatically stops in case of obstacles at the side and rear... A series of unique and innovative safety production measures have won CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd. the honor of first-class enterprise in safety production standardization in 2021. Recently, the reporter followed the supervisors and safety experts of the island Emergency Management Bureau to visit the enterprise workshop to explore the unique highlights in the construction of work safety standardization.
What are the unique highlights of the award-winning safety production of the enterprise?
Recently, the Qingdao Municipal Work Safety Committee issued a notice to carry out a major inspection of work safety in the city to "eliminate hidden dangers, fight against illegal activities and cure stubborn diseases". By means of open and covert visits, exposure of reports, special supervision on the implementation of the responsibilities of the Commission for Discipline Inspection and supervision, tracking and asking for results, accountability, regular scheduling, etc., the city's work safety situation has been ensured to remain stable. At the same time, Qingdao Municipal Emergency Management Bureau took the opportunity of the "year of style and ability improvement" to temper its style, improve its ability, move forward bravely, create a "trustworthy" brand of Party building, and set up a special column for news reports on the major inspection of work safety "to eliminate hidden dangers, fight against illegal and cure stubborn diseases", so as to track and report on relevant situations.
Recently, the reporter followed the supervisors and safety experts of Qingdao Emergency Management Bureau to CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd. located in Jihongtan street, Chengyang District. It is reported that, as China's high-speed train industrialization base, a leading design and manufacturing enterprise of high-grade railway passenger cars, a manufacturer of urban rail transit vehicles and an important export base of national rail transit equipment products, the enterprise has always attached great importance to safety production in recent years, and assisted the continuous improvement of safety production standardization construction with safety culture.
In March of this year, the emergency management department announced the list of class I enterprises in the industry and trade industry for work safety standardization in 2021, among which CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd. was listed. "This is the first assessment on the grading of first-class enterprises that have reached the standard after the revision and implementation of the measures for grading the construction of standardization of work safety in enterprises issued by the emergency management department." Yangshuxin, head of the Foundation Office of Qingdao Municipal Emergency Management Bureau, told the reporter that more than 60 enterprises in the machinery industry in China have passed the strict preliminary examination and declaration, and only 14 have finally passed the first-class rating, including CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd.
In yangshuxin's opinion, in addition to attaching great importance to the construction of work safety standardization, the enterprise can not get away from the promotion of work safety standardization by the emergency management departments at the provincial, municipal, district and sub district levels, and continue to provide assistance and guidance to the enterprise through such measures as stationing, diagnosis and guidance, so as to continuously improve the safety standardization management level of the enterprise.
Then, what are the unique highlights of CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd. in the construction of work safety standardization? To this end, reporters and safety experts came to the production workshop to find out.
Small protective board to protect the safety of high-altitude operation
After about ten minutes of traveling through the plant area, the vehicles stopped at the gate of a huge workshop. This is the workshop of CRRC Qingdao Sifang locomotive assembly branch. The workshop is clean, orderly, spacious and bright. Among the towering operating platforms on both sides are trains in manufacturing. Workers assemble parts in an orderly manner at their respective posts. At one of the operation platforms, several workers wore safety belts and other protective equipment and walked along the ladder to the operation platform five or six meters high, ready to install air conditioners on the top of the train carriage. The reporter found that before operation, the workers first pushed out sections of retractable protective plates on the lower platform. When they came to the roof for operation, they lowered the protective railings on both sides of the carriage. When workers work with their feet on the protective board, there is almost no gap between the carriage and the working platform.
Workers working on retractable protective boards
"According to the requirements of safety production, all platforms for high-altitude operation in the workshop are equipped with telescopic pedals and guardrails to fully ensure the safety of workers. Before operation, the telescopic pedals and guardrails need to be opened, and the guardrails and pedals can be recovered after the operation." Panxiaolei, leader of Metro external equipment team, mentioned the keyword "safe process" many times when introducing the safe operation process to the reporter.
When the retractable protective plate is not opened, there is an obvious gap between the train carriage and the operation platform
Yuyongqiang, the safety supervision director of the safety department of the enterprise, explained to the reporter that "safety advancement process" is an innovative mechanism they have explored in recent years in terms of safety production. In the previous production management, safety management and process management were separated. "To put it simply, the full implementation of safety advancement process is to consider planning safety management in the whole process, and each node should be controlled by a safety engineer." Yu Yongqiang takes the retractable protective plate installed on the elevated operation platform as an example. Due to the large size and high height of the rail vehicle, there is a gap between the vehicle and the elevated platform due to the uneven width of different vehicle models, and there is a risk of tripping or falling from the gap when working on the roof. For this reason, they fully considered the safety factors in the process design, and added the telescopic protective plate on the elevated operation platform, which essentially eliminated this potential safety hazard. Since the expansion plate was added, there has been no falling event. " Yu Yongqiang said that over the years since the implementation of the safety improvement process, the safety production of the enterprise has been greatly improved.
In the opinion of safety expert wangjianmei, the safety process of the enterprise is a model of management innovation. Safety production has been considered since the project design stage. When purchasing equipment, safety production needs have been put forward. After entering the factory, the equipment must be checked and accepted by safety personnel and evaluated by safety experts to see whether it meets the requirements of safety production. In the process of work, employees will also conduct risk assessment. If they find that there are still uncontrolled risks, they will continue to take engineering and technical measures for transformation, which essentially solves the problem of safety risks, so that all employees can truly participate in safety and pay attention to safety in the whole process.
There are objects behind the side, and the forklift stops automatically at a short distance
Walking down the elevated operation platform, a forklift slowly came to the side channel. It is different from other forklifts that the reporter has seen. When the forklift here is driving, there are red lines projected onto the ground in the left, right and rear directions of the body. "This is also our innovative safety technology for safety production." Xiaoxuefeng, deputy director of the safety department of the enterprise, introduced that forklifts are required to be used when moving parts across the plant, and there is a risk of vehicle injury when forklifts cross with people on the roads of the plant. They have made innovations and improvements in the safety of forklift operations.
The forklift is equipped with laser radar, and it will stop automatically when encountering obstacles at the rear of the side
Yangweipeng, the on-site staff, greeted the reporter to the front of the forklift. When the reporter approached 3 meters from the rear of the forklift, the forklift sounded an alarm. When he walked to the red line projected by the forklift onto the ground, the alarm became more urgent. "These three red lines are the clearance lights we have added to the forklift. When the forklift is started, the spotlight will automatically light up, forming a red eye-catching light ray on the ground in the left, right and rear directions of the vehicle to remind the surrounding pedestrians to avoid the forklift in real time." Yangweipeng said that at the same time, they also installed a reversing radar device on the forklift. When the person or object behind the forklift is about 3 meters away from the forklift, the radar will detect and send an alarm to remind forklift drivers and pedestrians; When the distance is close to the red line, the forklift will automatically cut off the power control and stop. "In addition, we have also configured a speed limit alarm device on the forklift. When the vehicle speed exceeds the set value, the speed limit alarm device will also cut off the oil circuit or circuit, force the vehicle to slow down and give an alarm." Yangweipeng said.
In order to demonstrate the intelligent distance recognition and automatic parking of the forklift, the worker pushed a small tool truck. When the forklift reverses and approaches the tool truck, the alarm and flashing alarm light will be sent out at a distance of 3 meters. When the red line of the forklift approaches the tool truck, the alarm will become urgent, the flashing frequency of the alarm light will increase, and the forklift will automatically stop. The forklift driver can step on the power pedal repeatedly, and the forklift will not move.
After watching the automatic induction function of forklift, safety expert wangjianmei repeatedly praised it. In her opinion, this is a typical embodiment of enterprise mechanization, intelligence and informatization. "When the forklift leaves the factory, it comes with buzzer warning and voice prompt. However, in practical operation, it is inevitable that the forklift will cross pedestrians in the visual blind area, which is prone to collision risk. The enterprise uses its own wisdom, uses radar to sense the distance between pedestrians and forklifts, and achieves automatic parking at close range. In terms of safety production, it improves the intrinsic safety of equipment through innovative intelligent safety intelligence." Wang said.
Promote "5m manager" and consolidate safety management system
During the interview in the workshop, the reporter found that in addition to the innovative and intelligent equipment that adds weight to the enterprise's safety production, there are also a number of safety management models to make the safety production more stable. In front of an elevated operation platform, the words "manager 5m" were written impressively. Every time the workers working under the platform used up a tool, they would carefully put it back in place, and timely summarize and sort out the equipment and parts around them.
Cuijiulong, the safety system director of the enterprise's safety department, explained that "5m manager" means that every employee is a "manager" in the 1.2m radius area of the operation site, who actively performs the maintenance of the site safety environment, operation protection and hanging, supervises the placement of materials, personnel code of conduct, etc., and issues red excellence cards to employees who perform well, and blue prompt cards to employees who perform poorly, After quantification, it is linked to performance to form a complete performance management system. "According to the observation of the plant, 1.2m is within the reach of the employees. Under normal conditions, it can control about 5m2 of on-site sanitation and on-site protection, which is acceptable from the custom and operable." Cuijiulong said.
Xuyanbo, a safety expert, believes that the "5m manager" system has effectively stimulated the employees' self-safety awareness, given full play to the employees' subjective initiative and enthusiasm for self-management, solved the practical problems existing in the safety management of the operation site, such as many points, a wide range, many hidden posts and difficult to manage by outsiders, and truly implemented the responsibility of everyone in safety production. "This system also organically combines risk management and control, hidden danger investigation and daily work, which is a good experience and method worthy of promotion." Xuyanbo said.
During the visit on the same day, the reporter learned that CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd. has many original and innovative measures to promote safety production standardization. Xiaoxuefeng, deputy director of the safety department of the enterprise, introduced that the enterprise attaches great importance to safety production and will allocate tens of millions of yuan to safety production every year. Most of the funds are used for the transformation of safety production technical measures and the improvement of intrinsic safety. Taking this year as an example, more than 100 projects have been included in the transformation of safety production technical measures. "With the in-depth development of work safety standardization, the company's safety management and technical and material prevention have been steadily improved, which has become an indispensable management means and standard for the company's safety management." Xiaoxuefeng said.
