Description

Technical Field

[0001] The utility model belongs to the technical field of cable equipment and relates to a cable fixing fixture inside a small-diameter drill hole in a mine. Background Art

[0002] With the continuous increase in the mining depth of the mining area, most of the underground electricity is extended by cable drilling, which can effectively shorten the cable laying length. The cable in the borehole is lowered by winch and wire rope traction. A cable clamp must be used to fix the cable and wire rope. At present, drilling is usually used to lower the cable, but the diameter of the clamp currently used is too large to pass through the borehole with a smaller diameter, and the clamp currently used is easy to get stuck in the hole.

[0006] Furthermore, the lower card plate has a rectangular structure.

[0007] Furthermore, the upper card plate has a rectangular structure, and the width of the upper card plate is smaller than the width of the lower card plate.

[0008] Furthermore, a first hook is fixed to the top of the first connecting rod, and a second hook is fixed to the top of the second connecting rod. The first hook and the second hook are C-shaped structures and are mirror-imaged.

[0009] Furthermore, the first connecting rod and the second connecting rod are hinged to the middle part of the lower clamping plate.

[0010] The beneficial effects of the utility model are: the cable is clamped by the lower clamping plate and the upper clamping plate, and the clamp is installed on the wire rope by the hooks on the first connecting rod and the second connecting rod. It is small in size, occupies little space, and can be easily passed through the drilled hole; it has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
