Telescopic cable interval extender

Abstract

The invention discloses a telescopic cable interval extender, through which two overhead conductors can be stably and reliably spaced apart to achieve sufficient operation space for electrical pole erection, and can be spaced apart in a convenient and rapid manner. The telescopic cable interval extender comprises a supporting pipe, two sliding rods, two locking bolts, and cable falling preventiondevices, wherein fixed ring magnets are arranged at both end surfaces of the supporting pipe; the two sliding rods are arranged in the supporting pipe in a sliding manner, one end of one sliding rod extends to the outer side of the supporting pipe through one end of the supporting pipe, one end of the other sliding rod extends to the outer side of the supporting pipe through the other end of the supporting pipe, and a cable hanging groove is formed on the outer side surface of each sliding rod and located on the outer side of the supporting pipe; the two locking bolts are in one-to-one correspondence with the sliding rods, and are arranged on the supporting pipe to fix the corresponding sliding rods; and the cable falling prevention devices are in one-to-one correspondence with the slidingrods.

Description

technical field [0001] The invention relates to an auxiliary device for electric power construction, in particular to a telescopic cable distance extender. Background technique [0002] When a new electric pole needs to be erected on a certain section of the high-voltage line, two parallel overhead conductors need to be pulled apart to increase the distance between the overhead conductors and provide enough work space for the pole operation of the electric pole. [0003] At present, there are the following operation methods to spread the two overhead conductors: [0004] The first operation method is to use two electrified trolleys to carry out the operation. The electrified trolley stops at the two overhead conductors, and the construction workers pull the overhead conductors through the electrified trolley. This operation method requires the cooperation of the electrified trolley and several construction personnel, and the operation is inconvenient; [0005] The second op...

[0004] The first operation method is to use two electrified trolleys to carry out the operation. The electrified trolley stops at the two overhead conductors, and the construction workers pull the overhead conductors through the electrified trolley. This operation method requires the cooperation of the electrified trolley and several construction personnel, and the operation is inconvenient;

[0005] The second operation method is to tie insulated working ropes on two overhead conductors respectively, and two construction workers pull the overhead conductors apart on the ground. Stable, the distance between two overhead conductors is unstable, there is a big safety hazard
