Before use, the rubber-tyred mine car is opened to a position 0.5m away from the roadway side, the car body direction is adjusted, the car runs along the cable direction, and the U-shaped carrier roller frame and a cable hook of the underground high-voltage cable to be installed are approximately at the same horizontal height. And then the underground high-voltage cable to be installed passes through the space between the two horizontal carrier rollers at the top of the upright post after passing through the front carrier roller.

Then the rubber-tyred car is slowly started, the cable is firstly lifted to the height of the protection frame by the front carrier roller, and then the cable is supported to the height of the corresponding cable hook by the upright post and the U-shaped carrier roller frame on the upright post. And then, a worker holds the supporting rod by hand to push the cables into the corresponding cable hooks until all the cables are hung on the cable hooks, and the construction is completed.

The heavy underground high-voltage cable is lifted by the rubber-tyred car, the front carrier roller and the U-shaped carrier roller frame, so that the labor intensity of workers is greatly reduced.

The stand column comprises an inner pipe and an outer pipe, wherein the lower end of the outer pipe is fixed on a rubber-tyred car, a plurality of opposite pin holes are formed in two sides of the outer wall of the outer pipe from top to bottom, the lower part of the inner pipe is inserted into the outer pipe, one or two opposite pin holes are formed in two sides of the outer wall of the inner pipe, one pin hole of the inner pipe can be opposite to the pin hole of the outer pipe, a bolt is jointly penetrated, the stand column is fixed at different heights, and the U-shaped roller frame is fixed at the top end of the stand column. By the design, the height of the stand column can be conveniently adjusted according to the requirement, so that the U-shaped carrier roller frame is located at the same height as the corresponding cable hook.

As optimization, the top of the supporting rod is provided with two branches which are Y-shaped fork heads, each branch is sleeved with a roller sleeve, the distance between the lower ends of the two roller sleeves is smaller than the distance between the outer diameters of underground high-voltage cables to be installed and the upper ends of the two roller sleeves. When the cable is lifted, the roller sleeve can roll on the cable, rolling resistance is small, and an outer insulating layer of the cable is not easy to damage.

The underground high-voltage cable hanging device is simple in structure, labor-saving and convenient, and is suitable for installing and laying underground high-voltage cables.
