Description

Technical Field

[0001] This invention belongs to the field of power maintenance technology, specifically a substation safety fall arrest structure for power maintenance operations. Background Technology

[0002] Power maintenance refers to the inspection, testing, maintenance, and repair of equipment in a power system to ensure its normal operation. Job responsibilities include: targeted inspection and maintenance of substations, troubleshooting substation faults, ensuring normal equipment operation, handling equipment malfunctions within substations, and participating in the patrol, routine inspections (live-line testing, power quality monitoring), and cleaning of unmanned substations. Power maintenance typically employs methods such as visual inspection, condition analysis, and graphical transformation. Furthermore, power maintenance personnel must master relevant operating procedures and be familiar with the performance, working principles, and operating methods of power equipment to ensure they can quickly diagnose the cause of power faults and take appropriate countermeasures.

[0003] Existing fall protection structures often focus on optimizing distress calls and preventing secondary injuries. However, in actual use, power maintenance positions are typically staffed by two people, and fall protection structures require high-altitude work permits. Therefore, the issue of single-person operation or violation of regulations does not exist. Consequently, falls during operations can generally be detected quickly. Adding extra equipment only increases the force of the fall. The real danger lies in the fact that when a fall occurs, the two safety ropes often become entangled, easily strangling the worker's neck and limbs. This makes self-rescue difficult and increases the difficulty of rescue. Furthermore, during a fall, the traditional five-point harness, with the safety rope wrapped around the waist, causes the worker's lower limbs to bear significant downward force, easily leading to dislocations, fractures, and other problems. Moreover, the five-point harness primarily bears the force on the waist, resulting in uneven force distribution and a high risk of local soft tissue contusions. Summary of the Invention

[0004] The technical solution adopted in this invention is as follows: A substation safety fall arrest structure for power maintenance operations, comprising:

[0005] The storage shell and the mounting plate are fixedly disposed at the center of the outer wall of the storage shell;

[0006] A buffer assembly is located on the outer wall of the storage shell, comprising: a main buffer rod, guide wheels, clamping wheels, a drive rod, a drive groove, a limiting shell, a buffer cable, a storage wheel assembly, a rotating frame, a lifting frame, and a damping structure. One end of the main buffer rod is rotatably embedded in the protruding end of the mounting plate. The guide wheels and clamping wheels are rotatably inserted into the outer walls of both ends of the main buffer rod. Both ends of the drive rod are respectively rotated and inserted into the center of the outer walls of both ends of the main buffer rod. The drive groove is opened in the inner wall of the drive rod.

One end of the lifting frame is embedded in the center of the inner wall of one end of the drive rod. The damping structure is located on the outer wall of the mounting plate. The storage wheel assembly is rotatably embedded in the center of the inner wall of the storage shell. Both ends of the buffer cable are respectively wound around the inner wall of the storage wheel assembly.

[0007] Furthermore, the damping structure includes a drive shaft, a damper, and a storage cylinder.

[0009] Furthermore, the drive shaft is fixedly installed at the center of the bottom of the outer wall of the lifting frame, and the bottom end of the drive shaft is fixedly installed at the top end of the damper.

[0010] Furthermore, the buffer cable, guide wheel, and clamping wheel are matched with each other.

[0011] Furthermore, a lock is fitted on one side of the outer wall of the buffer cable, and the lock has installation openings on the outer walls at both ends.

[0012] Furthermore, the outer wall of the storage shell has operation ports on both sides, and the operation ports are matched with the buffer rope.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In this invention, the cushioning component can reduce the falling force on the worker during a fall, avoiding uneven stress on the five-point harness that could lead to bone fractures and other problems.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] Example 1

[0026] Reference Figure 1 - Figure 5 A substation safety fall arrestor structure for power maintenance operations, comprising:

[0027] The storage shell 1 and the mounting plate 10 are fixedly disposed at the center of the outer wall of the storage shell 1.

[0028] A buffer assembly is located on the outer wall of the housing 1. The buffer assembly includes a main buffer rod 2, guide wheels 3, clamping wheels 4, a drive rod 5, a drive groove 501, a limiting shell 6, a buffer cable 9, a housing wheel set 11, a rotating frame 14, a lifting frame 15, and a damping structure. One end of the main buffer rod 2 is rotatably embedded in the protruding end of the mounting plate 10. Both ends of the main buffer rod 2 are rotatable, facilitating the displacement of the guide wheels 3 and clamping wheels 4. The guide wheels 3 and clamping wheels 4 are rotatably inserted into the outer walls of both ends of the main buffer rod 2. Both ends of the drive rod 5 rotate and are inserted into the center of the outer walls of both ends of the main buffer rod 2. The drive groove 501 is formed in the inner wall of the drive rod 5. The limiting shell 6 is fixedly installed. At the top of the outer wall of the mounting plate 10, the rotating frame 14 is rotatably embedded in the inner wall of the drive groove 501. The ends of the rotating frames 14 that are close to each other are slidably embedded in the inner wall of the limiting shell 6. The inner wall of the limiting shell 6 is embedded with a buffer spring 18, which can reduce the impact force of the rotating frame 14. One end of the lifting frame 15 is embedded in the center of the inner wall of one end of the drive rod 5. The damping structure is located on the outer wall of the mounting plate 10. The storage wheel set 11 is rotatably embedded in the center of the inner wall of the storage shell 1. The storage wheel set 11 consists of two pulleys, which are respectively wound around the two ends of the two buffer cables 9 in opposite directions. The two ends of the buffer cables 9 are respectively wound around the inner wall of the storage wheel set 11.

[0029] Reference Figure 1 - Figure 5 The damping structure includes a drive shaft 16, a damper 17, and a storage cylinder 20. The storage cylinder 20 is embedded in the inner wall of the mounting plate 10, and the damper 17 is embedded in the inner wall of the storage cylinder 20. The inner wall of the mounting plate 10 has a lifting groove 1001, which can improve the movement accuracy of the lifting frame 15. A limiting block 19 is fixedly installed on the outer wall of the lifting frame 15, and the limiting block 19 matches the lifting groove 1001. The drive shaft 16 is fixedly installed at the bottom center of the outer wall of the lifting frame 15, and the bottom end of the drive shaft 16 is fixedly installed at the top end of the damper 17. The buffer cable 9, the guide wheel 3, and the clamping wheel 4 match each other.

[0030] Reference Figure 1 - Figure 5 A lock 7 is fitted on one side of the outer wall of the buffer cable 9, and the outer walls of both ends of the lock 7 are provided with mounting holes 8. The outer walls of the storage shell 1 are provided with operating ports 102 on both sides. The operating ports 102 facilitate the movement of the buffer cable 9 and are matched with the buffer cable 9. A sealing plate 101 is embedded in the outer wall of the storage shell 1. Ratchets 12 are fitted on both sides of the outer wall of the storage wheel assembly 11. The ratchet 12 can increase the rotational resistance of the storage wheel assembly 11 and reduce the extraction rate of the buffer cable 9. The outer walls of the storage shell 1 and the sealing plate 101 that are close to each other are provided with locking teeth 13 by torsion bar rotation, and the locking teeth 13 are matched with the ratchet 12.

[0031] Working principle:

[0032] First, the mounting plate 10 is sewn to the outside of the five-point safety harness. Then, two safety ropes with double-headed hooks are attached, one end of which is clipped to the mounting port 8 of the lock 7, and the other end is wrapped around the designated position. When the worker falls, the safety rope pulls the lock 7, causing the buffer cable 9 to rise. Then, the storage wheel assembly 11 is pulled and rotated by the buffer cable 9. The ratchet 12 and the locking teeth 13 engage to slow down and reduce the pulling speed of the buffer cable 9. After the safety rope is pulled out, due to the worker's falling force, the main buffer rod 2 continues to rotate through the buffer cable 9, the guide wheel 3, and the clamping wheel 4. This causes the drive rod 5 on the main buffer rod 2 to press down on the lifting frame 15. At this time, the rotating frame 14 presses the buffer spring 18 inside the limiting shell 6, further reducing the impact force of the fall. At this time, under the limit of the lifting groove 1001 and the limiting block 19, the drive shaft 16 of the lifting frame 15 presses the damper 17 to achieve buffering again and reduce the impact force of the fall.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
