Description

Technical Field

[0001] This invention relates to the field of power safety technology, and more specifically, to a safety belt suspension device for power maintenance. Background Technology

[0002] When inspecting electrical equipment at heights, a suspended safety harness is an indispensable piece of safety equipment for maintenance workers. The harness uses a five-point harness to provide comprehensive protection and stability. It is also equipped with suspension devices such as fall arrestors to prevent falls. In use, the suspension device is connected to pre-set anchor points, which are typically steel plates or rings with connection holes. Only after the suspension device is connected to the anchor points can the safety of the maintenance worker be guaranteed. Currently, because the anchor point positions are fixed, the optimal maintenance position for the electrical equipment or the worker is often misaligned with the anchor point. In this case, the anchor point and the safety harness on the worker are not on the same vertical line. If the worker falls, the taut safety rope will pull the worker down below the anchor point, and the worker will sway during this process. If there are obstacles such as walls around the anchor point, the worker will collide with these obstacles, increasing the risk of injury and failing to meet the requirements for comprehensive safety assurance.

[0003] According to the safety belt suspension device for transformer operation disclosed in Chinese Publication No. CN117919622A, it includes: a first fixed bracket, a second fixed bracket, a wire winch, a wire rope, and a hook. The first fixed bracket is installed on one side of the transformer gantry. The present invention fixes the wire winch to one side of the transformer gantry through the first fixed bracket and to the other side of the transformer gantry through the second fixed bracket. The wire rope on the wire winch is connected to the hanging ring on the second fixed bracket through the hook.

[0004] The aforementioned applications suffer from limitations in the location of the anchor points, which can cause swaying when maintenance workers fall, potentially leading to collisions with obstacles around the anchor points and increasing the risk of injury. This fails to meet the requirements for comprehensive safety assurance. Therefore, this application provides a safety belt suspension device for power maintenance to address this issue. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a safety belt suspension device for power maintenance, which extends the suspension assembly around the attachment point to keep the safety belt in a vertical state, so as to avoid the swinging situation after the worker falls, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A safety belt suspension device for power maintenance includes an attachment point, a suspension assembly on the outside of the attachment point, the suspension assembly consisting of a balancing assembly and a movable assembly, a safety rope fixedly connected to the bottom of the suspension assembly, a safety belt fixedly connected to the bottom end of the safety rope, the balancing assembly including a balancing frame on the outside of the attachment point, a first connecting shaft slidably connected to one side of the balancing frame, a first rotating handle fixedly connected to one end of the first connecting shaft, the first connecting shaft being inserted into the inside of the attachment point, a first fastening nut threadedly connected to the outside of the first connecting shaft, a first clamping plate slidably connected to the outside of the first connecting shaft, the first fastening nut rotatably connected to one side of the first clamping plate, and a connecting stud fixedly connected to the end of the first connecting shaft away from the first rotating handle.

[0007] In a preferred embodiment, a second connecting shaft is slidably connected to the side of the balance frame away from the first connecting shaft, and a second rotating handle is fixedly connected to one end of the second connecting shaft.

[0008] In a preferred embodiment, a second fastening nut is threadedly connected to the outer side of the second connecting shaft, a second clamping plate is slidably connected to the outer side of the second connecting shaft, the second fastening nut is rotatably connected to one side of the second clamping plate, and the second connecting shaft and the connecting stud are threadedly connected.

[0009] In a preferred embodiment, the second connecting shaft is inserted into the hanging point, and both the first clamp and the second clamp abut against the hanging point.

[0010] In a preferred embodiment, the movable component includes a track frame rotatably connected to the bottom of the balance frame, a movable shaft slidably connected to the inner side of the track frame, and a plurality of positioning holes provided on the outer side of the movable shaft.

[0011] In a preferred embodiment, a positioning post is slidably connected inside the track frame. The positioning post is inserted into the inside of the positioning hole. A suction plate is fixedly connected to one end of the positioning post, and a pull ring is fixedly connected to one side of the suction plate.

[0012] In a preferred embodiment, a magnet is fixedly connected to one side of the track frame, and the magnet is arranged in an attractive manner with the suction plate.

[0013] In a preferred embodiment, a support frame is fixedly connected to the bottom of the movable shaft, a groove is provided inside the support frame, a sliding shaft is slidably connected to the inner side of the groove, a lifting ring is sleeved on the outer side of the sliding shaft, a connector is sleeved at the bottom end of the lifting ring, and the connector is fixedly connected to the safety rope.

[0014] In a preferred embodiment, the support frame is internally slidably connected to a plurality of limiting members, and the support frame is internally slidably connected to a transmission rod. A top block is fixedly connected to the top of the transmission rod, and the top block is arranged in an abutting position against the limiting members.

[0015] In a preferred embodiment, a connecting plate is fixedly connected to one end of the transmission rod, a spring is fixedly connected to one side of the connecting plate, the spring is fixedly connected inside the support frame, a pull rope is fixedly connected to the side of the connecting plate away from the spring, a fixing frame is fixedly connected to one end of the support frame, a guide wheel is rotatably connected to the inner side of the fixing frame, and the pull rope is slidably connected to the inner side of the guide wheel.

[0016] The technical effects and advantages of this invention are as follows: This invention, by setting up a suspension assembly, connects the suspension assembly to the anchor point, and then uses a support frame to replace the anchor point and finally connect to the safety belt. Even if the safety belt and the anchor point are misaligned, the safety belt is still connected to the connector and located directly below the connector. Therefore, when a worker falls, the safety belt will not swing due to deviation. This allows for the worker to move in the desired reverse direction without swaying during a fall and colliding with obstacles, thus providing comprehensive safety protection for the worker. The balancing assembly can clamp and fix the hanging point, so that after the device is fixed, the balancing assembly cannot move in any direction, thus giving the device good stability. Good stability can reduce the swaying of workers falling during subsequent use. At the same time, the clamping setting of the first clamp and the second clamp can make the device applicable to various types of hanging points, avoiding limitations in use. By using the support frame and sliding shaft, workers can further adjust the position of the sliding shaft according to the actual situation. When workers need to make small movements, the sliding shaft can be adjusted to the corresponding position at the same time to avoid small deviations between the safety belt and the connecting parts. This ensures that the safety belt is always directly below the connecting parts, which not only ensures that workers will not swing and impact during a fall, but also makes the device highly flexible to meet usage requirements.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Refer to the instruction manual appendix Figures 1-8 As shown in the figure, a safety belt suspension device for power maintenance according to an embodiment of the present invention includes a hanging point 1. The hanging point 1 is pre-installed on the building surface such as the wall above the maintenance area for easy maintenance. A suspension assembly is provided on the outside of the hanging point 1. The suspension assembly consists of a balance assembly and a movable assembly. A safety rope 29 is fixedly connected to the bottom of the suspension assembly. A safety belt 30 is fixedly connected to the bottom end of the safety rope 29. The safety belt 30 is a conventional five-point safety belt. In actual use, the safety rope 29 can be connected to a fall arrester as needed, and then connected to a connector 18 through the fall arrester.

[0021] The balancing assembly includes a balancing frame 2 located outside the hanging point 1. A first connecting shaft 3 is slidably connected to one side of the balancing frame 2. A first rotating handle 4 is fixedly connected to one end of the first connecting shaft 3. The first connecting shaft 3 is inserted into the hanging point 1. A first fastening nut 5 is threadedly connected to the outside of the first connecting shaft 3. A first clamping plate 6 is slidably connected to the outside of the first connecting shaft 3. The first fastening nut 5 is rotatably connected to one side of the first clamping plate 6. A connecting stud 28 is fixedly connected to the end of the first connecting shaft 3 away from the first rotating handle 4. A first connecting stud 28 is slidably connected to the side of the balancing frame 2 away from the first connecting shaft 3. Two connecting shafts 7, the first connecting shaft 3 and the second connecting shaft 7 have the same diameter. One end of the second connecting shaft 7 is fixedly connected to a second rotating handle 8. The outer side of the second connecting shaft 7 is threadedly connected to a second fastening nut 9. The outer side of the second connecting shaft 7 is slidably connected to a second clamping plate 10. The second fastening nut 9 is rotatably connected to one side of the second clamping plate 10. The second connecting shaft 7 and the connecting stud 28 are threadedly connected. The second connecting shaft 7 is inserted into the inside of the hanging point 1. The first clamping plate 6 and the second clamping plate 10 both abut against the hanging point 1. The first clamping plate 6 and the second clamping plate 10 have the same structure.

[0022] It should be noted that, when using this device, the first connecting shafts 3 on both sides are inserted into the holes of the hanging point 1, and the first handle 4 or the second handle 8 is rotated to connect the second connecting shaft 7 to the connecting stud 28. At this time, the second connecting shaft 7 and the first connecting shaft 3 are a single shaft. By rotating the first fastening nut 5 and the second fastening nut 9, the first clamping plate 6 and the second clamping plate 10 are brought closer to each other until they are in contact with both sides of the hanging point 1. After tightening the first fastening nut 5 and the second fastening nut 9, the second clamping plate 10 and the first clamping plate 6 clamp the hanging point 1, thereby fixing the device in a fixed state. At this time, the balancing component cannot move in any direction, thus giving the device good stability. Good stability can reduce the swaying situation caused by workers falling during subsequent use. At the same time, the clamping setting of the first clamping plate 6 and the second clamping plate 10 allows the device to be applied to various types of hanging points, avoiding limitations in its use.

[0023] Furthermore, such as Figure 3As shown, the movable component includes a track frame 11 rotatably connected to the bottom of the balance frame 2. A movable shaft 12 is slidably connected to the inner side of the track frame 11. The track frame 11 is rotatably configured so that the movable shaft 12 can extend in any direction to meet various needs in actual use. Multiple positioning holes 13 are provided on the outer side of the movable shaft 12. A positioning post 31 is slidably connected to the inside of the track frame 11. The positioning post 31 is inserted into the inner side of the positioning hole 13. A suction plate 32 is fixedly connected to one end of the positioning post 31. The suction plate 32 is made of metal. A pull ring 27 is fixedly connected to one side of the suction plate 32. A magnet 33 is fixedly connected to one side of the track frame 11. The magnet 33 and the suction plate 32 are arranged in an attractive manner. The positioning post 31 and the suction plate 32 are fixed by magnetic attraction, which not only prevents the positioning post 31 from falling off and losing its limit on the movable shaft 12, but also improves the convenience of use.

[0024] A support frame 14 is fixedly connected to the bottom of the movable shaft 12. A sliding groove 15 is provided inside the support frame 14. A sliding shaft 16 is slidably connected to the inner side of the sliding groove 15. The diameter of the sliding shaft 16 inside the sliding groove 15 is equal to the length of the upper and lower sides of the sliding groove 15. A lifting ring 17 is sleeved on the outer side of the sliding shaft 16. A connector 18 is sleeved on the bottom end of the lifting ring 17. The connector 18 is fixedly connected to the safety rope 29.

[0025] Both the lifting ring 17 and the connector 18 can rotate to improve the flexibility of the safety rope 29 and the safety belt 30, thus avoiding restrictions on the movement of maintenance workers.

[0026] Multiple limiting members 19 are slidably connected inside the support frame 14. The top of the limiting member 19 is set with an arc-shaped profile. A transmission rod 20 is slidably connected inside the support frame 14. A top block 21 is fixedly connected to the top of the transmission rod 20. The top block 21 is set with a trapezoidal profile and is set in abutment with the limiting member 19. A connecting plate 22 is fixedly connected to one end of the transmission rod 20. A spring 23 is fixedly connected to one side of the connecting plate 22. The spring 23 is fixedly connected inside the support frame 14. A pull rope 26 is fixedly connected to the side of the connecting plate 22 away from the spring 23. A fixing frame 24 is fixedly connected to one end of the support frame 14. A guide wheel 25 is rotatably connected to the inner side of the fixing frame 24. The pull rope 26 is slidably connected to the inner side of the guide wheel 25.

[0027] It should be noted that, after the balance component is connected and fixed to the hanging point 1, the positioning pin 31 is removed, allowing the positioning hole 13 to slide inside the track frame 11. The positioning hole 13 is slid until it protrudes to the designated side and stops after protruding to the required length. After adjustment, the positioning pin 31 is inserted into the corresponding positioning hole 13, and the suction plate 32 and magnet 33 are ensured to be attracted. At this time, the hanging ring 17 is offset from the hanging point 1. Since the safety belt 30 is connected to the connector 18 through the safety rope 29, the safety belt 30 is ensured to be directly below the connector 18, thus avoiding misalignment of the safety belt 30. Therefore, when a worker falls, there will be no swinging due to misalignment. After a vertical fall, the worker will quickly stabilize, thus completely preventing the worker from colliding with obstacles such as buildings due to swinging, thereby avoiding impact injuries to the worker.

[0028] Meanwhile, the rotatable design of the track frame 11 allows for adjustment of the orientation of the movable shaft 12 according to actual conditions, fully adapting to the multi-directional maintenance needs encountered during actual use. Furthermore, the sliding shaft 16 can slide within the slide groove 15. After determining the length of the protruding side of the movable shaft 12, the worker can further adjust the position of the sliding shaft 16 according to actual conditions. This allows the sliding shaft 16 to be adjusted to the corresponding position simultaneously when the worker needs to make small movements, preventing small dimensional deviations between the safety belt 30 and the connecting member 18. The adjustment method involves pulling the pull rope 26, which, guided by the guide wheel 25, causes the connecting plate 22 to slide the transmission rod 20 to one side. Simultaneously, the spring 23 is stretched. When the top block 21 moves away from the bottom of the limiting member 19, the limiting member 19 loses its position. The device slides downwards to the limit. At this time, the worker pulls the safety rope 29 in the direction of the required adjustment, thereby causing the sliding shaft 16 to move inside the slide groove 15, thus completing the adjustment of the sliding shaft 16. After the adjustment is completed, the pull rope 26 is released, causing the transmission rod 20 to reset. The limiting member 19 extends under the guide of the inclined surface of the top block 21 to limit the sliding shaft 16. The limiting of multiple limiting members 19 prevents the sliding shaft 16 from sliding freely inside the slide groove 15. This allows the worker to make corresponding adjustments to the sliding shaft 16 when moving further away from the hanging point 1, ensuring that the safety belt 30 is always directly below the connecting member 18. This not only ensures that the worker will not swing and cause an impact when falling, but also makes the device highly flexible to meet the needs of use.
