Embodiment Construction

[0023] In order to better understand the technical solutions of the present invention, the present invention will be further described with reference to the accompanying drawings.

[0024] Such as Figure 1-2 As shown, a replacement ground wire crossing auxiliary device includes two pulleys 1, which are connected by a connecting rod 9, and the distance between the two pulleys can be adjusted through the connecting rod. 3 is located below the pulley in the pulley.

[0025] A cross bar 6 is provided on the pulley, a positioning device 5 is provided on the cross bar, and the positioning device is connected to the connecting rod.

[0026] The cross bar is a hollow cavity, and the positioning device 5 includes a bolt set in a screw hole and matched with the screw hole.

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

[0028] A limit device 2 is also provided on the pulley.

[0029] A load-bearing cable hanging point 4 is also provided on the pul...

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 ground wire replacement device for a power transmission line, in particular to a ground wire replacement auxiliary device. 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 crossovers under the line where the optical cable is replaced, such as power lines, roads, and railways. To ensure the safety of the replacement of optical cables, conventional construction methods need to set up crossovers for power lines, roads, and railways. [0003] Conventional construction methods are used to erect cross-over racks. First, the construction is cumbersome and consumes manpower and material resources; second, the land occupation of the cross-over rack causes the increase in compensation for young crops; third, the power line that is crossed requires power outage coordination, whic...
