Description

Technical Field

[0001] The utility model relates to the technical field of hanging ladders, in particular to a hanging ladder for emergency repair of power grids. Background Art

[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. At the same time, it can be understood that in the power transmission and transformation industry expansion project, when the power grid is repaired in the power engineering, it is often necessary to use a hanging ladder to climb to the high power grid to carry out construction work. The two adjacent climbing poles of the existing hanging ladder are generally fixed. When carrying out the power grid repair work, it is sometimes necessary to adjust the distance between the two climbing poles to adapt to the requirements of the repair site environment and achieve the purpose of completing the repair task safely, quickly and cleanly. The authorization announcement number CN105888531B discloses a power grid repair hanging ladder, which solves the problem that the existing hanging ladder cannot quickly and reliably adjust the distance between adjacent climbing poles. It includes two parallel ladder connecting ropes arranged between the upper insulating plate and the lower insulating plate, and a sleeve locking piston cylinder is fixedly arranged on the outer wall of the sleeve outside the through hole. This ladder can adjust the spacing between climbing poles, but when this ladder is adjusted, it is necessary to insert the connecting rope through a spike to fix it. Such reciprocating puncture of the connecting rope will shorten the service life of the connecting rope, resulting in the ladder being unable to be used for a long time, causing a waste of resources. For this reason, we propose a power grid emergency repair ladder. Utility Model Content

[0022] Reference Figure 3-Figure 4The suspension mechanism includes three hooks 13, and the three hooks 13 are rotatably connected to the top plate 1. A ring 14 is rotatably installed on the three hooks 13, and a connecting belt 15 is fixedly installed on the three rings 14. An adjusting block 16 is provided on the three connecting belts 15, and an inner buckle 17 is provided on the three adjusting blocks 16. Three card slots 18 are provided on the top plate 1, and the three inner buckles 17 are engaged with the three card slots 18.
