Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 , figure 2 In the shown embodiment, an auxiliary tool for preventing workers from falling over the insulator string of power transmission tension pole and tower includes two positioning plates 1 and two handle bodies 2 that can be sleeved on the insulator 4. The positioning plate 1 is a waist-shaped through hole 12 on the inner side, and the two ends are semicircular back-shaped long discs. The edge of the waist-shaped through hole 12 on the inner side of the positioning plate 1 is also provided with a rubber ring 11. The rubber ring 11 is Also be provided with several rubber convex grains 13, described rubber convex grains 13 are right-angled triangles, one of which is perpendicular to the rubber ring 11, and the beveled side is arranged downwards along the rubber ring 11; There are two T-shaped slots 3 arranged symm...

The invention discloses an auxiliary tool for preventing a worker from falling from a power transmission strain tower insulator string, and the tool comprises two positioning discs which can sleeve aninsulator, and two handle bodies. The long sides of the positioning discs at one side are provided with two symmetric T-shaped grooves, and the interior of each T-shaped groove is provided with a plurality of positioning blocks, wherein positioning grooves are respectively formed between the adjacent positioning blocks. Each handle body comprises a handle rod and a handle pedestal, and the handlepedestal is also provided with a positioning pin in a long axis direction. Two handle pedestals of the handle bodies are respectively connected to the T-shaped grooves of the two positioning discs atthe same position in a rotating position, thereby enabling the two positioning discs and the two handle bodies to be connected with each other. The invention has the following beneficial effects that(1), the tool can balance the force of the insulator in a horizontal direction; (2), the tool improves the safety of the worker; (3), the tool improves the work efficiency of the worker.
Description
technical field [0001] The invention relates to an electric tool, in particular to an auxiliary tool for preventing operators from falling over insulator strings of power transmission tension poles and towers. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] At present, the erection of single-string insulators on tension poles and ...
