Description

Technical Field

[0001] The utility model relates to the technical field of coal mine cable traction, in particular to a coal mine cable traction mechanism. Background Art

[0002] Mining cables refer to wire and cable products used in ground equipment and underground equipment used in the coal mining industry, including cables for coal mining machines, conveyors, communications, lighting and signal equipment, as well as electric drill cables, cap lamp wires and power cables for underground mobile substations. Mining cables are all flame-retardant cables. In mine power supply systems, 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] A coal mine cable traction mechanism is disclosed in the Chinese utility model patent with the announcement number CN 213602304 U, including a bottom plate, a support seat fixedly connected to the top of the bottom plate, a fixed plate fixedly connected to the top of one side of the support seat, a support seat fixedly connected to the top of the fixed plate, and a rotating shaft rotatably connected to the inner side of the support. The utility model uses the cooperation between the first pulley and the active roller to make the active roller have an electric transmission mechanism, and by setting a power box, it is convenient for the traction mechanism to store battery packs and some common tools, which solves the problem that when the staff transports the cable in the coal mine or outputs the cable from the coal mine, it will consume a lot of labor of the staff, and the work efficiency is low. When the cable is laid in the underground well, the cable is often damaged to a certain extent due to the wellhead. In view of the above-mentioned related technologies, the inventor believes that there are the following defects: since the cable will be flat, deformed and uneven in diameter after long-term use, the cable traction by a group of traction devices is easy to cause traction failure, and it is impossible to have continuous traction on the cable.

By adjusting the first driven wheel 23 to descend, the first driving wheel 22 and the first driven wheel 23 can slightly squeeze the cable, and the cable can be pulled when the first driving wheel 22 rotates, which can facilitate the installation of the cable and is also suitable for cables of different sizes.
