Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and in particular to an intelligent safety suspended operation platform. Background Technology

[0002] Typically, after locomotives enter the depot, personnel need to inspect, patrol, and clean crucial components of the EMU (Electric Multiple Unit) system, such as pantographs, insulators, and high-voltage cables, to ensure the safety performance of these vital parts. Because the inspection, patrol, and cleaning of EMUs involves a wide range of work and a large workload, and because rooftop work is high-altitude work, there is a dual risk of falls and electric shock, making accidents highly likely. Therefore, personnel must wear safety belts and other protective equipment and strictly adhere to operating procedures.

[0003] However, there are no attachment devices for workers to wear safety belts on the sides and top of the vehicle roof. Workers can only attach their safety belts to the overhead contact line. Applying force to the overhead contact line for a long time will cause the overhead contact line fixing device to shift and loosen, affecting the normal operation of the overhead contact line. Furthermore, due to the long intervals between work areas, workers need to frequently attach and detach their safety belts and travel back and forth across the vehicle roof, which cannot improve work efficiency and easily leads to the risk of missing safety belts. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent safety suspended work platform that can monitor the safety status of workers in real time, effectively improve the safety and efficiency of high-altitude operations, eliminate the need for frequent safety belt removal and removal, simplify the operation process, monitor the wearing status of safety belts and the safety status during operation, and quickly detect and prevent workers from falling in the event of a fall, while simultaneously issuing an alarm signal to remind relevant personnel to provide timely rescue. This effectively reduces operational risks, protects the personal safety of workers, and significantly improves the efficiency and reliability of high-altitude operations.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The intelligent safety suspended operation platform, in the EMU depot inspection room, includes two platforms, columns, and overhead contact lines. The columns are arranged on the two platforms and are spaced apart along the platform's extension direction. The overhead contact lines are suspended between the columns on the two platforms to provide power to the locomotive. The intelligent safety suspended operation platform includes:

[0007] A safety suspension mechanism includes a rail assembly and a suspension assembly. The rail assembly is located between two adjacent columns on one side of the platform, with its height between the locomotive and the overhead contact line, and its length direction parallel to the extension direction of the platform. The suspension assembly includes a sliding assembly, a safety sling, and an emergency brake. The sliding assembly is slidably connected to the rail assembly and moves along the length direction of the rail assembly. One end of the safety sling is connected to the sliding assembly, and the other end is connected to the safety rope. The emergency brake is located on the safety sling and can quickly lock the safety sling when it slides down rapidly.

[0008] The safety protection mechanism includes a disconnecting switch and a protective component. The disconnecting switch, the protective component, and the contact network are electrically connected. The disconnecting switch can control the power supply and disconnection of the protective component and the contact network. The protective component can monitor the operating status of the safety suspension mechanism in real time, and can promptly issue an alarm signal when a safety abnormality occurs.

[0009] Furthermore, the protective component includes a limit switch, which is electrically connected to the disconnect switch. The limit switch is disposed on the hanging rail assembly and is used to restrict the use of the suspension component. When the disconnect switch controls the protective component to be energized, the limit switch allows the suspension component to move on the hanging rail assembly, and the limit switch can record the number of suspension components used.

[0010] Furthermore, the protective component also includes a pressure sensor and a real-time monitoring device. The pressure sensor is located on the suspension rail assembly and is electrically connected to the real-time monitoring device. It is used to detect the pressure on the suspension rail assembly and feed it back to the real-time monitoring device. The real-time monitoring device is located on the column and is used to monitor the operating status of the safety suspension mechanism in real time.

[0011] Furthermore, the protective component also includes an audible and visual alarm, which is electrically connected to the pressure sensor and the real-time monitoring component.

[0012] Furthermore, the safety protection mechanism also includes a controller, which is located on the platform, and the controller, the disconnect switch, and the real-time monitoring device are electrically connected.

[0013] Furthermore, the suspended rail assembly includes a suspended rail frame and a suspended rail. The two ends of the suspended rail frame are fixedly connected to the adjacent columns on either side of the platform, and its width extends toward the other side of the platform, while its length is parallel to the extension direction of the platform. The suspended rail is located on the side of the suspended rail frame facing the platform and is arranged along the length direction of the suspended rail frame.

[0014] Furthermore, the hanging rail frame includes multiple H-shaped frames, which are sequentially and fixedly connected.

[0015] Furthermore, the sliding assembly includes a pulley, which is slidably connected to the suspension rail. A lifting lug is fixedly connected to the pulley, and one end of the lifting lug is connected to the safety sling. The other end of the safety sling is connected to a buckle, which is detachably connected to the safety rope.

[0016] Furthermore, the emergency braking device employs a fall arrestor.

[0017] Furthermore, multiple suspension components are provided, and the multiple suspension components are slidably suspended on the hanging rail component in sequence.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides an intelligent safety suspended work platform, including a safety suspension mechanism and a safety protection mechanism. The safety suspension mechanism includes a rail assembly and a suspension assembly. The design of the rail assembly and sliding assembly allows the suspension assembly to move smoothly along the rail assembly. Workers can maintain a stable connection to their safety belts during the sliding process, eliminating the need for repeated attaching and detaching or changing positions as in traditional work methods. The sliding assembly allows for easy movement to both sides of the platform, quickly reaching the required work location. The sliding design of the suspension assembly reduces the time spent on complex operations during movement, thereby improving overall work efficiency. By electrically connecting the disconnecting switch, the protection assembly, and the overhead contact line, when the disconnecting switch is tripped, the overhead contact line is de-energized, and the safety protection assembly... Power supply: When the disconnecting switch is closed, the contact network is energized, and the protective components are de-energized. Real-time power control is achieved through the disconnecting switch. When operators perform maintenance or inspection, the power supply between the locomotive and the contact network can be automatically cut off, ensuring that the power source is safely disconnected, thereby greatly reducing the risk of electric shock, ensuring the safety of operators, and preventing safety accidents caused by accidental power restoration. The protective components monitor the operating status of the safety suspension mechanism in real time. If any safety abnormality occurs, an alarm signal can be issued in a timely manner to notify relevant personnel for emergency handling, effectively avoiding accidents. At the same time, by setting the emergency brake on the safety sling, when any safety abnormality occurs and the safety sling slides down rapidly, the emergency brake can be locked quickly to prevent operators from being injured due to accidental slippage.

[0032] Please refer to Figures 1 to 4As shown, this utility model provides an intelligent safety suspended work platform that can monitor the safety status of workers in real time, effectively improving the safety and efficiency of high-altitude operations. It can not only automatically monitor the wearing status of workers' safety belts and their safety status during the operation, eliminating the need for frequent safety belt removal and simplifying the operation process, but also quickly detect and prevent workers from falling in the event of a fall, while simultaneously issuing an alarm signal to remind relevant personnel to provide timely rescue. This effectively reduces operational risks, protects the personal safety of workers, and significantly improves the efficiency and reliability of high-altitude operations. The EMU depot inspection bay includes two platforms 100, columns 200, and an overhead contact line. The columns 200 are arranged on the two platforms 100 and are distributed at intervals along the extension direction of the platforms 100. The overhead contact line is suspended between the columns 200 on the two platforms 100 to provide power to the locomotive. The intelligent safety suspended operation platform includes a safety suspension mechanism 1 and a safety protection mechanism 2. The safety suspension mechanism 1 includes a rail assembly 11 and a suspension assembly 12. The rail assembly 11 is located between two adjacent columns 200 on one side of the platform 100, and its height is between the locomotive and the overhead contact line. Its length is parallel to the extension direction of the platform 100. The suspension assembly 12 includes a sliding component, a safety sling 122, and an emergency brake. 121, the sliding component is slidably connected to the hanging rail component 11 and moves along the length of the hanging rail component 11. One end of the safety sling 122 is connected to the sliding component, and the other end is connected to the safety rope. The emergency brake 121 is provided on the safety sling 122. When the safety sling 122 slides down rapidly, the emergency brake 121 can quickly lock the safety sling 122. The safety protection mechanism 2 includes an isolating switch and a protection component 21. The isolating switch, the protection component 21 and the contact network are electrically connected. The isolating switch can control the power supply and de-energization of the protection component 21 and the contact network. The protection component 21 can monitor the operating status of the safety suspension mechanism 1 in real time. When a safety abnormality occurs, the protection component 21 can issue an alarm signal in time.

[0033] By fixing the overhead rail assembly 11 to one side of the platform 100, with its two ends connected to two adjacent columns 200, its height is located between the locomotive and the overhead contact line, and its length is parallel to the extension direction of the platform 100. The sliding component of the suspension assembly 12 is slidably connected to the overhead rail assembly 11 and moves along the length of the overhead rail assembly 11. The design of the overhead rail assembly 11 and the sliding component allows the suspension assembly 12 to move smoothly along the overhead rail assembly 11. The operator can maintain a stable connection to the safety belt during the sliding process, without having to repeatedly attach or detach or change positions as in traditional operation methods. The sliding component allows easy movement to both sides of the platform 100, quickly reaching the location where operation is required. The sliding design of the suspension assembly 12 reduces the time for operators to perform complex operations during movement, thereby improving overall work efficiency. An emergency brake 121 is provided on the safety sling 122. When the safety sling 122 experiences rapid descent, an emergency brake is applied. It can quickly lock to prevent workers from being injured due to accidental slips. By electrically connecting the disconnecting switch, protective component 21, and contact network, when the disconnecting switch is open, the contact network is de-energized and the safety protective component 21 is energized; when the disconnecting switch is closed, the contact network is energized and the protective component 21 is de-energized. Real-time power control is achieved through the disconnecting switch. When workers are performing maintenance or inspection, the power supply between the locomotive and the contact network can be automatically cut off to ensure that the power source is safely disconnected, thereby greatly reducing the risk of electric shock, ensuring the safety of workers, and preventing safety accidents caused by accidental power restoration. The protective component 21 monitors the operating status of the safety suspension mechanism 1 in real time. If any safety abnormality occurs, it can promptly issue an alarm signal to notify relevant personnel for emergency handling, effectively avoiding accidents. At the same time, the emergency braking component 121 can quickly lock the safety sling 122, maximizing the safety of workers and reducing accident losses. Specifically, the emergency braking component 121 can, but is not limited to, use a fall arrestor. Fall arrestors are existing technology and will not be described in detail here.

[0034] Combination Figure 2 and Figure 4As shown, to improve operational safety, in some embodiments, the protective component 21 includes a limit switch 211, which is electrically connected to the disconnecting switch. The limit switch 211 is mounted on the suspension rail assembly 11 and is used to restrict the access of the suspension component 12. When the disconnecting switch energizes the protective component 21, the limit switch 211 allows the suspension component 12 to move on the suspension rail assembly 11, and the limit switch 211 can record the number of suspension components 12 accessed. Specifically, through the linkage between the limit switch 211 and the disconnecting switch, the limit switch 211 only allows the movement of the suspension component 12 when the disconnecting switch is tripped (the contact wire is de-energized), restricting the arbitrary access of the suspension component 12 and preventing operators from operating the equipment while the contact wire is energized. This prevents misuse or improper operation of the equipment, thereby reducing the risk of electric shock and further improving the safety of high-altitude operations. Furthermore, the limit switch 211 can record the number of suspension components 12 accessed, facilitating the tracking of equipment usage during operations and improving the standardization of the working environment.

[0035] Combination Figure 2 and Figure 3 As shown, to quickly and accurately locate abnormal electrical current, in some embodiments, the protective component 21 further includes a pressure sensor 212 and a real-time monitoring device 213. The pressure sensor 212 is mounted on the suspension rail assembly 11 and electrically connected to the real-time monitoring device 213, used to detect the pressure on the suspension rail assembly 11 and feed it back to the real-time monitoring device 213. The real-time monitoring device 213 is mounted on the column 200 and used to monitor the operating status of the safety suspension mechanism 1 in real time. The pressure sensor 212 and the real-time monitoring device 213 are linked; when the pressure sensor 212 detects abnormal continuous pressure, the real-time monitoring device 213 can quickly track and locate the specific location of the abnormality, notify relevant personnel for emergency handling, and improve response efficiency. It is understood that the real-time monitoring device 213 can, but is not limited to, using a bullet camera; no specific limitation is made here. Furthermore, to make the pressure sensor 212 more stable, a sensor mounting bracket can also be installed on the suspension rail assembly 11. Furthermore, the protective component 21 also includes an audible and visual alarm device, which is electrically connected to the pressure sensor 212 and the real-time monitoring device 213. The audible and visual alarm device can emit an audible and visual signal immediately after the pressure sensor 212 detects an abnormality, attracting the attention of people in the vicinity and improving the recognition efficiency of the abnormal alarm. Combined with the specific location information fed back by the real-time monitoring device 213, it enables relevant personnel to react quickly, investigate the cause of the abnormality in a timely manner, and take rescue measures.

[0036] like Figure 1As shown, to achieve multi-functional linkage control, in some embodiments, the safety protection mechanism 2 further includes a controller 22, which is mounted on the platform 100. The controller 22, the disconnect switch, and the real-time monitoring device 213 are electrically connected. The controller 22 can receive status data from the real-time monitoring device 213 and quickly activate the disconnect switch to isolate potentially dangerous equipment areas and prevent accidents. Based on data from the real-time monitoring device 213 and the pressure sensor 212, the controller 22 can dynamically adjust the operating mode of the intelligent safety suspended work platform. For example, the controller 22 can set the rated threshold of the pressure sensor 212, reducing manual intervention and improving the safety and reliability of equipment operation. Specifically, the controller is equipped with a display screen, allowing the user to observe the feedback data from the real-time monitoring device 213.

[0037] like Figure 1 As shown, to improve the stability of the overhead rail assembly 11, in some embodiments, the overhead rail assembly 11 includes an overhead rail frame 111 and an overhead rail 112. The overhead rail frame 111 is fixedly connected at both ends to adjacent columns 200 on either side of the platform 100, extends in width toward the other side of the platform 100, and its length is parallel to the extension direction of the platform 100. The overhead rail 112 is located on the side of the overhead rail frame 111 facing the platform 100 and is arranged along the length of the overhead rail frame 111. The fixed connection of the two ends of the overhead rail frame 111 to adjacent columns 200 on the platform 100 forms a stable support structure, enhancing the stability of the overhead rail assembly 11. The overall rigidity and load-bearing capacity ensure the safe operation of the suspended work platform. The width of the suspension frame 111 extends towards the platform 100 on the other side, allowing the working range of the suspension assembly 12 to cover the entire top area of ​​the locomotive. Operators can complete maintenance, repair, or installation work on the locomotive top without frequently adjusting the suspension rail 112 or changing working positions. The suspension rail 112 is located on the side of the suspension frame 111 facing the platform 100 and is arranged along the length of the suspension frame 111, allowing the suspension assembly 12 to move flexibly and easily achieve straight-line movement on the suspension rail 112, ensuring smooth movement of the work platform on the track. Furthermore, the suspension frame 111 includes multiple H-shaped frames, which are sequentially and fixedly connected. The H-shaped frame structure has high bending and compressive strength, providing sufficient support when the suspension frame 111 bears the working load, ensuring that the frame is not easily deformed or unstable. Even further, the connection between the suspension frame and the column can be made more stable by using a well-type support.

[0038] like Figure 1As shown, to improve the stability of the suspension assembly 12, in some embodiments, the sliding assembly includes a pulley, which is slidably connected to the suspension rail 112. A lifting lug 123 is fixedly connected to the pulley, and one end of the lifting lug 123 is connected to a safety sling 122. The other end of the safety sling 122 is connected to a buckle 124, which can connect to the safety rope. The slidable connection between the pulley and the suspension rail 112 allows the safety sling 122 to slide freely along the suspension rail 112, facilitating flexible adjustment of the working range by the operator at different positions and improving work efficiency. The lifting lug 123 is fixedly connected to the pulley, and both ends of the safety sling 122 are connected to the lifting lug 123 and the buckle 124 respectively, ensuring a firm connection between the sliding assembly and the safety rope and improving the safety of the system.

[0039] like Figure 1 As shown, in order to improve work efficiency, in some embodiments, multiple suspension components 12 are provided, and multiple suspension components 12 are slidably suspended on the hanging rail component 11; wherein, by working together, multiple workers can work at the same time, effectively improving work efficiency.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
