Description

Technical Field

[0001] This invention relates to the field of rescue equipment technology in power maintenance, and specifically to an auxiliary climbing tool for power maintenance. Background Technology

[0002] In high-altitude climbing operations such as power pole erection, communication base station maintenance, and street light pole repair, the traditional protection mode of "all-around safety belt + pole harness + back safety rope," while supported by clear industry standards, has many pain points in practical operation: 1. The operation process is cumbersome, requiring manual repetition of the steps of "threading, knotting, tightening, and checking" for the pole harness and back safety rope. The requirements for the standardization of knotting are strict, and under the condition of high physical exertion at height, it is easy to make mistakes or omissions, which weakens the protective effect. 2. The alternating switching of protective components is time-consuming, and frequent disassembly and assembly disrupt the work rhythm. In scenarios with high time requirements, such as emergency repairs, workers are prone to simplifying operations in order to speed up the process. 3. Weak safety awareness among personnel, coupled with the difficulty of on-site management, leads to repeated violations of safety regulations and the simplification of protective procedures, creating a fatal risk of falls from heights.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] Please see Figure 1-13 This invention discloses an auxiliary climbing tool for power maintenance. This tool improves upon existing climbing tools by replacing the single, ordinary rope with hooks at the top and bottom with a structure where two elastic ropes 2 are connected to a safety harness lock 3, and a climbing lock 1 is attached to the upper end of each elastic rope 2. The elastic ropes 2 can deform to meet the worker's long-distance needs within a shorter actual distance, making climbing operations more convenient. The two climbing locks 1 improve climbing efficiency.

[0020] The climbing lock 1 has the following specific structure: a semi-elliptical hook 1.1 with an opening at the bottom; an L-shaped claw 1.3 is rotatably connected to the lower right side of the main body of the hook 1.1 via a pin; and a transmission rod 1.2 is rotatably connected to the upper left side of the main body of the hook 1.1 via another pin. The transmission rod 1.2 is a shell-like structure with an opening on the right side and a U-shaped cross-section, the opening of which is larger than the thickness of the hook 1.1. A return spring 1.4 is connected to the lower left side of the hook body 1.1, and the left end of the return spring 1.4 is connected to the U-shaped bottom of the inner side of the transmission rod 1.2.

[0021] The L-shaped claw 1.3 has its short side on the left and its long side on the right. The short side is a shell-like structure with openings on the top, bottom, and left side, while the right side is integrated with the long side. Both the short side and the main body of the hook 1.1 have upward-protruding arc-shaped grooves. These grooves are open from front to back, and the two parts have coaxially aligned arc-shaped grooves. A locking groove extends upward from the left end of the arc-shaped groove. The right end of the transmission rod 1.2 connects to an auxiliary locking shaft 1.2.1, which can slide along the locking groove and the arc-shaped groove. Figure 5 As shown, when the auxiliary locking shaft is located within the arc-shaped groove, the pawl 1.3 can rotate around the hook 1.1 with the hinge point as the center, as... Figure 7 As shown, the jaw 1.3 and the end of the hook 1.1 are connected as follows: Figure 4 As shown, close to and as Figure 6 The separation shown achieves either a closed loop or an open loop. When the auxiliary locking shaft is located as... Figure 3 When the latch 1.3 is in the slot shown, its position on the hook 1.1 is locked, as shown. Figure 2 As shown.

[0022] At the end of the long side of the L-shaped structure of the chuck 1.3, there is a... Figure 6 and Figure 8 The anti-detachment groove 1.3.2 shown cooperates with the retaining ring at the end of the hook 1.1 to prevent the claw 1.3 from separating from the hook 1.1 in case of accident.
