Problems solved by technology
However, due to the narrow working space in the shaft and the high-altitude operation, there are few equipment and tools available, and basically can only be moved by manpower. The construction is more difficult, the labor intensity of the workers is high, and the labor consumption is large. The safety management is extremely difficult.
In addition, when moving the high-voltage cable, it is easy to cause the high-voltage cable to touch the well wall and cause damage

The invention relates to the technical field of cable construction, and provides an auxiliary cable fixing device and a construction method for a cable in a vertical shaft. The auxiliary cable fixing device comprises a steel wire rope and a plurality of fixing clamps arranged on the steel wire rope at intervals; the fixing clamp comprises two clamping plates which are oppositely arranged, each clamping plate is provided with a first clamping part and a second clamping part which protrude outwards, the clamping plates are provided with fasteners, the two clamping plates are connected together through the fasteners, and two clamping spaces capable of containing the steel wire rope and the cable are formed; a plurality of limiting rings are arranged on the steel wire rope at intervals, and the upper ends of the limiting rings support the fixing clamp to prevent the fixing clamp from sliding downwards. According to the construction method for the cable in the vertical shaft, the cable auxiliary fixing device is adopted, the cable is far away from the inner wall of the vertical shaft when the cable is put down, and after the cable is put down to a preset height, the cable can be rotated around the steel wire rope to be close to the cable hook on the inner wall of the vertical shaft, and workers can conveniently install the cable in the cable hook.
Description
technical field [0001] The invention relates to the technical field of cable construction, in particular to an auxiliary cable fixing device and a cable construction method in a shaft. Background technique [0002] Under mines, especially mines developed by shafts, the high-voltage electricity on the surface needs to be led to the underground when underground construction uses electricity. Therefore, high-voltage cables need to be constructed in shafts. The construction process mainly includes the lowering and installation of high-voltage cables. When the length of the shaft is long, due to the large diameter and weight of the high-voltage cable, sufficient safety measures must be taken to prevent the construction personnel from falling during the lowering of the high-voltage cable. of damage. When the high-voltage cable is fixedly installed in the shaft, it is necessary to move the high-voltage cable in a small range and move it to the cable hook and clip on the shaft wall...
