Description
Technical Field
[0001] The utility model relates to the technical field of mining cables, in particular to a mining cable with good cold resistance effect. Background Art
[0002] Mining cable is the abbreviation of coal mine cable. Mining cables are all flame-retardant cables, which are generally used for the mobile laying of various mining power devices under coal mines. In the mine power supply system, high-voltage power supply lines generally use armored cables, and their failure rate is much lower than that of low-voltage power supply lines.
[0003] Since mining cables are used from outside the mine to inside the mine, current mining cables are generally exposed outdoors. This results in ice, snow and rain falling directly on the surface of the cables when used in winter and condensing on the surface of the cables, thereby causing certain impacts and damage to the cables through low temperatures, affecting the normal use of the cables. There is room for improvement. Utility Model Content

[0012] Preferably, the circular friction pad overlaps the surface of the cable body. When the cable body is dragged on the inner wall of the arc frame, it can rotate on the surface of the circular rod through the circular friction pad, reducing the friction between the cable body and the arc frame, thereby reducing the loss on the surface of the cable body.
[0013] The beneficial effects of the utility model are:
[0014] 1. By setting up arc-shaped rubber pads, strip-shaped limit blocks, positioning rods and electric heating plates, it is convenient to cover the upper part of the arc frame when in use, preventing ice, snow and rain from falling directly on the surface of the outdoor cable body, thereby improving the protection effect of the cable body.

[0023] A strip-shaped slot is provided on the upper surface of the arc frame 3, and the strip-shaped limit block 7 is adapted to the strip-shaped slot. A slide groove is provided on the right side of the arc frame 3, and a movable block 8 is slidably connected to the inner bottom wall of the slide groove. A pull rod 9 is fixedly connected to the right side of the movable block 8, and a spring 10 is sleeved on the surface of the pull rod 9. The left end of the spring 10 is fixedly connected to the right side of the movable block 8, and the right end of the spring 10 is fixedly connected to the right inner wall of the slide groove. The right end of the pull rod 9 is fixedly connected to a pull plate 11, and a positioning rod 12 is fixedly connected to the left side of the pull plate 11, and the positioning rod 12 is adapted to the positioning circular hole;
[0024] Pulling the strip limit block 7 can drive the arc-shaped rubber pad 6 to extend out of the arc frame 3. At this time, the pull plate 11 is pulled to the right, and the movable block 8 is driven to move to the right through the pull rod 9 and squeeze the spring 10. At the same time, the pull plate 11 drives the positioning rod 12 to disengage from the strip card slot. After the strip limit block 7 is stuck in the strip card slot, the pull plate 11 is released, and the reaction force generated by the spring 10 can drive the positioning rod 12 to insert into the positioning circular hole on the side of the strip limit block 7, thereby limiting and fixing the strip limit block 7.

The left and right sides of the electric heating plate 15 are respectively overlapped with the opposite surfaces of the movable silicone pad 18 and the positioning silicone pad 14;
[0026] The electric heating plate 15 is connected to the power supply through the embedded wire sleeve 13. The electric heating plate 15 can emit heat and provide a certain amount of heat to the surface of the cable body 1 in the inner wall of the arc frame 3 to prevent the cable body 1 from being frozen and damaged and affecting normal use.

Since the surface of the cable is in contact with the surface of several circular friction pads 20, after dragging the cable, the friction generated between the cable and the circular friction pad 20 will drive the circular friction pad 20 to rotate on the surface of the circular rod 19, thereby reducing the wear effect on the cable surface and improving the protection of the cable. When the outdoor environment is too cold or snowing, the staff pulls the strip limit block 7 to make the strip limit block 7 drive the arc rubber pad 6 to extend, and insert the strip limit block 7 into the strip card slot.
