However, the translation of the cable has always been an important problem. The traditional cable trough is usually fixedly installed on the ground or other structures. Once installed, it is difficult to move and adjust the position. If the cable needs to be adjusted during the translation process, the cable trough needs to be removed and reinstalled, which not only consumes a lot of manpower, material resources and time, but also may damage the cable and affect the safety and stability of power transmission. Therefore, it is of great practical significance to develop a movable cable trough that can be easily moved, flexibly adjusted and effectively protect the cable. SUMMARY

[0005] Preferably, a pair of scissors guide pull rods are arranged between the adjacent cable bracket trolleys, and the cable bracket trolleys are combined into a whole by the scissors guide pull rods.

[0006] Preferably, the cable bracket trolleys at both ends are a head-end trolley and a tail-end trolley, the head-end trolley is adjacent to the plug-in house, and the tail-end trolley is adjacent to the electric trolley.

[0007] Preferably, a drag chain is connected to the head-end trolley adjacent to the plug-in house, and the other end of the drag chain is cooperated with the electric trolley.

[0008] Preferably, the housing is a box-shaped structure with one open end, and both ends of the box-shaped structure are equipped with detachable doors; the cable tray trolley slides with the guide rail and its top does not extend beyond the housing.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: during relocation, all cable trays and cables are stored inside the housing, facilitating overall movement and transportation; when the drilling rig is moved horizontally, only guide rails need to be laid, and the cables will move with the drilling rig to meet different movement distances, eliminating the need for secondary cable disassembly and reassembly, greatly shortening the time for cable disassembly and reinstallation, and improving work efficiency; during handling, an electric trolley is used to pull the cable trays and trolleys, sequentially retracting the cables and trolleys into the housing, achieving rapid cable packaging and greatly shortening the time for cable disassembly and packaging; the combination of cable trays and cable chains can accommodate a significantly increased cable length; and a plug-in / turn-off housing is provided to facilitate cable disassembly and rapid connection.
