Embodiment Construction

[0023] In order to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as Figure 1-2 As shown, a replacement ground wire spanning auxiliary device includes two pulleys 1, and the two pulleys are connected by a connecting rod 9. The distance between the two pulleys can be adjusted through the connecting rod. The upper phase wire 3 is positioned at the below of pulley in described tackle.

[0025] The tackle is provided with a crossbar 6, and the crossbar is provided with a positioning device 5, and the positioning device is connected to the connecting rod.

[0026] The crossbar is a hollow cavity, and the positioning device 5 includes bolts set in the screw holes and matched with the screw holes.

[0027] The screw holes are located on the front surface or the rear surface of the cross bar.

[0028] A limiting device 2 is also provided on the tac...

Abstract

The invention provides a crossing assist device capable of replacing a ground wire. The crossing assist device comprises two pulley blocks, wherein the two pulley blocks are connected through a connecting rod; the distance between the two pulley blocks can be adjusted through the connecting rod; and an upper-phase wire is located at the lower part of a pulley in each pulley block. The crossing assist device can be arranged on the upper-phase wires as a crossing structure for replacing a common overhead ground wire with an OPGW optical cable. An increase of compensation for crops caused by land occupation of a common console crossing structure is avoided; the influence of a cooperative power failure of a crossed circuit on the power supply reliability is avoided; the risk caused by a high-altitude routing operation is reduced; and the crossing construction reliability is improved.

Description

technical field [0001] The invention relates to a device for replacing a ground wire of a power transmission line, in particular to a crossover auxiliary device for replacing a ground wire. Background technique [0002] According to the requirements of communication planning, the transmission line often needs to replace the old ordinary overhead ground wire with OPGW optical cable. There are often many power lines, roads, railways and other crossings under the line where the optical cable is replaced. In order to ensure the safety of the optical cable replacement work, the conventional construction method needs to set up spanning frames for power lines, roads, and railways. [0003] The conventional construction method to build a spanning frame, first, the construction is cumbersome and consumes manpower and material resources; second, the land occupation of the spanning frame increases the compensation fee for young crops; Waiting for cumbersome procedures. [0004] Some ...
