Description
Technical Field
The invention belongs to the technical field of high-altitude operation of electric power and communication systems, and particularly relates to a rope locking device for a pole for ascending a height.
Background
The power and communication system is necessary for high-altitude operation, and is assisted by a special climbing tool. The work high above the ground generally means work high above the ground, and means work performed by a person at a height with reference to a certain position. The national standard GB/T3608 and 2008 high place operation classification stipulates that the operation at high places with the possibility of falling more than 2m (including 2m) of the falling height reference surface is called high place operation. In accordance with this regulation, the range of high-altitude operations involved in the electrical power industry is quite wide. In the power construction work, if the operation is performed on a frame with the length of more than 2m, the high-altitude work is obtained. The correct selection of the climbing tool and the skilled control of the method of using various climbing tools are one of the important conditions for ensuring the safety work of electricians. The common climbing tools comprise ladders, pedals, climbers and the like, the auxiliary climbing tool comprises a waistband, a safety rope and a waist rope, the climbing operation articles comprise lifting ropes, lifting bags and the like, and certain safety risks exist in use. For high-altitude operators, the extensive pole climbing operation in mountainous areas and rural power lines is quite common nowadays. The construction, operation and maintenance of new electric power and communication projects can not be operated at high altitude. The labor intensity of the climbing operation is very high and the safety factor is not high during the high-altitude operation. Therefore, the labor intensity of operators is reduced, the novel pole climbing tool for cement poles and steel pipe poles is manufactured according to the requirements of the current safety form, and the novel pole climbing tool is used for construction and emergency repair of electric power and communication systems.

The upper end surface of the rope locking device body 30 is connected with a cover plate 47 by a screw, and the middle part of the cover plate is provided with a through hole for a rope to pass through; the upper end of the wedge-shaped slide block 32 is connected with the lower surface of a cover plate 47 by a compression spring 48, and the top block 45 is an annular top block (the middle part of the top block is a through hole for a rope to pass through).
The compression spring 48 presses the wedge 32 downward to lock the cord lock. The top block 45 jacks up the wedge-shaped slide block 32, overcomes the elasticity and unlocks the rope locking device.
