[0002] A safety harness attachment point is a safety accessory used to secure and support a personal safety harness, ensuring that workers receive effective fall protection when working at heights or in other hazardous environments.

[0003] In the existing technology, with the development of the power grid, the power system equipment is operating safely and stably, and equipment accidents are decreasing year by year. However, safety accidents during power system operations still occur frequently, among which falls from height are particularly noteworthy. To meet operational needs, most power equipment is designed to be more than two meters high. Frontline production operations often require climbing to maintain equipment. Among the many pieces of equipment, the main transformer has a large operating range, and workers often lack safety belt protection when moving between different work locations. Existing safety belt attachment devices are usually fixed structures. For example, patent number CN2022218014884 (An Outdoor Main Transformer Safety Belt Attachment Device) discloses a safety belt attachment device installed around the main transformer. However, this attachment device is fixed and difficult to remove once installed. It also has a complex structure, which is not conducive to portable transportation. Therefore, this utility model proposes a detachable substation safety belt attachment device to solve the above problems. Utility Model Content

In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0023] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a detachable substation safety belt attachment device, comprising: a base plate 1, a lifting seat 2 provided on the upper side of the base plate 1, the lifting seat 2 being slidably connected to the limiting rods 3 on both sides, a vertical rod 4 installed on one side of the limiting rods 3, the bottom of the vertical rod 4 being fixedly connected to the lifting seat 2, the vertical rod 4 being provided with safety belt attachment points, the base plate 1 being detachably installed on both sides at the bottom of the column 5, a fixed shaft 6 being fixedly sleeved inside the column 5, the fixed shaft 6 being slidably connected to the end of the connecting rod 7, the connecting rods 7 being rotatably connected by a pin, and a limiting clamp 8 being fixedly installed on the top of the column 5.

[0024] In this utility model, two sets of hanging point devices are used in conjunction, respectively installed on both sides of the substation. Taking one set of hanging point devices as an example, after the suspension rope passes through the safety belt hanging point at the top of the upright 4, the base plate 1 is placed on the ground, thereby supporting the limiting rod 3 and the upright 4 through the base plate 1. Then, the two uprights 5 are pulled to both sides, thereby causing the end of the connecting rod 7 to slide on the fixed shaft 6. The connecting rods 7 are rotatably connected by a pin, thereby allowing the two uprights 5 to unfold under the limiting of the connecting rods 7. Then, the uprights 5 are spliced ​​together. The base plate 1 is fixedly supported on both sides, and the lifting seat 2 lifts the fixed pole 4 on it, which moves upward. The pole 4 slides stably under the limit of the limiting clamp 8 until the lifting seat 2 reaches the top of the column 5. After the same operation is performed on the other side of the hanging point device, the suspension rope can be lifted to the top of the substation, which is convenient for the staff to work on the substation. The above structure allows the hanging point device to be quickly installed and removed from the perimeter of the substation. The lifting structure is simple, easy to operate, and has very good practicality.

[0025] Example 2: Based on Example 1, four columns 5 are arranged in a rectangular array around the surface of the base plate 1. A slot 9 is provided on one side of the bottom of each column 5. Insert blocks 10 are fixedly connected to both sides of the base plate 1, and the insert blocks 10 slide into the slots 9. The columns 5 are arranged around the base plate 1 to facilitate stabilization. The columns 5 can be joined to the base plate 1 through the sliding connection between the slots 9 and the insert blocks 10. The upper surface of the base plate 1 is fixedly connected to the limiting rod 3. The lifting seat 2 is slidably fitted onto the limiting rod 3 on both sides. A connecting plate 11 is provided on one side of each insert block 10, and one side of the connecting plate 11 is fixedly connected to the base plate 1. The bottom of the limiting rod 3 is fixedly connected to the base plate 1, limiting the lifting seat 2 and ensuring its stability during sliding. Two connecting plates 11 are arranged symmetrically about the center plane of the base plate 1. The connecting plate 11 is fixedly connected to the side of the base plate 1 away from the insert block 10. The upper surface of the connecting plate 11 is fixedly connected to the electric push rod 12. The output end of the electric push rod 12 is fixedly connected to a T-shaped shaft 13. Sprockets 14 are rotatably sleeved on both sides of the T-shaped shaft 13. A chain 15 is meshed on the sprockets 14. One end of the chain 15 is fixedly connected to the lifting seat 2, and the other end of the chain 15 is fixedly connected to the connecting plate 11. The connecting plate 11 provides fixed support for the electric push rod 12. The output end of the electric push rod 12 is fixedly connected to the bottom of the T-shaped shaft 13. Sprockets 14 are rotatably sleeved on the T-shaped shaft 13. Limiting rings are provided on both sides of the sprocket 14. The limiting rings are fixedly sleeved on the T-shaped shaft 13, thereby limiting the sprocket 14 through the limiting rings. The chain 15 meshes with the sprocket 14 for transmission. One end of the chain 15 is fixedly connected to one side of the lifting seat 2 through the connecting seat, and the other end of the chain 15 is also fixedly connected to one side of the connecting plate 11 through the connecting seat.

[0026] After the suspension rope passes through the safety belt attachment point installed at the top of the upright 4, the base plate 1 is placed stably on the ground. The base plate 1 provides stable support for the limit rod 3, upright 4, and connecting plate 11. Then, the upright 5 is fixedly installed around the base plate 1 by sliding the slot 9 on the side wall of the upright 5 with the insert 10 fixedly installed on the side wall of the base plate 1. The upright 5 reinforces the stability of the entire device. The electric actuator 12 is electrically connected to the external terminal control equipment. At this time, by controlling the output end of the electric actuator 12 to extend outward, it drives the T-shaped shaft 13 to move upward. The T-shaped shaft 13 then drives its... The sprockets 14 installed on both sides move upward. Since one end of the chain 15 is fixedly connected to the connecting plate 11 through the connecting seat, this end is the movable end. The other end of the chain 15 is fixedly connected to one side of the lifting seat 2 through the connecting seat, this end is the fixed end. Thus, through the meshing transmission between the sprockets 14 and the chain 15, the movable end of the chain 15 drives the lifting seat 2 to move upward. In turn, the lifting seat 2 drives the upright 4 to move upward under the limit rod 3. While the upright 4 moves upward, it slides and connects with the limit clamp 8. Thus, the limit clamp 8 limits the upright 4 and improves its stability during the movement.

[0027] Example 3: Based on Example 2, a threaded sleeve 16 is provided on the upper side of the chain 15. An adjusting rod 17 is fitted inside the threaded sleeve 16 and is threadedly connected to the adjusting rod 17. The lower surface of the threaded sleeve 16 is fixedly connected to the top of the column 5. A sliding hole 18 is provided on one side wall of the column 5. The sliding hole 18 is slidably connected to both ends of the T-shaped shaft 13. A threaded sleeve 16 is fixedly installed on the top of the column 5. The adjusting rod 17 is connected to the internal thread of the threaded sleeve 16, so that the adjusting rod 17 can be twisted to make it move laterally within the threaded sleeve 16. The sliding hole 18 on one side wall of the column 5 limits the sliding of the T-shaped shaft 13. The support rod 19 is slidably sleeved in the other side wall of the column 5. Nuts 20 are threaded to both ends of the support rod 19. The end of the connecting rod 7 is fixedly connected to the sliding sleeve 21. The sliding sleeve 21 is slidably sleeved on the fixed shaft 6. The support rod 19 is slidably sleeved on the other side wall of the column 5. The support rod 19 is fixed to the column 5 by the nuts 20, thereby enhancing the stability of the column 5. The connecting rod 7 is slidably connected to the fixed shaft 6 through the sliding sleeve 21.

[0028] After the initial splicing of the base plate 1 and the column 5 through the insert block 10 and the slot 9 is completed, the support rod 19 is slidably sleeved between the two columns 5, and the two nuts 20 are placed on both sides of one column 5. After the support rod 19 is sleeved, the support rod 19 is fixed to the column 5 by twisting the nuts 20, thus completing the final installation of the base plate 1 and the column 5. Then, the electric push rod 12 is started to push the T-shaped shaft 13 to move upward, thereby indirectly driving the column 4 to move upward. The T-shaped shaft 13 slides under the limit of the sliding hole 18 until the lifting seat 2 reaches the top of the column 5. At this time, the T-shaped shaft 13 reaches the top of the sliding hole 18. Limit holes are opened at both ends of the T-shaped shaft 13. The limit holes are slidably connected to the adjusting rod 17. By rotating the adjusting rod 17, the two adjusting rods 17 move towards each other, so that one end of the adjusting rod 17 slides into the limit hole opened at the end of the T-shaped shaft 13, thereby fixing the T-shaped shaft 13 and further increasing the stability of the lifting seat 2.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
