Embodiment Construction
[0012] When the shearer is working, it is necessary to arrange multiple hydraulic supports in rows along the working face for support, such as Figure 1-3 As shown, the shearer with cable retractable function according to the present invention includes a shearer body 2 located below the hydraulic support top beam 1 and a cable 3 fixedly connected to the tail of the shearer body 2, the cable 3. The arrangement position after extraction has changed compared with the past. The existing equipment usually arranges the cable 3 in the cable trough of the conveyor, but in the present invention, the cable 3 is arranged on the hydraulic support top beam 1 above the shearer body 2 , and are pulled and rewound through the cable unwinding device 6 and the cable receiving device 7 respectively arranged in the middle section of the shearer body 2 and the machine head. Specifically, a cable guiding connector 4 is hingedly arranged on each hydraulic support top beam 1 , and the lower end of th...

The invention relates to a coal cutter with cable take-up and pay-off functions. The coal cutter comprises a coal cutter body located below a plurality of hydraulic supporting frame top beams arranged in a row, and a cable fixedly connected to the tail of the coal cutter body. The hydraulic supporting frame top beams are each provided with a cable guide connector, and the lower ends of the cable guide connectors are connected with cable guide troughs. A cable pay-off device is arranged on the middle section of the coal cutter body. A cable take-up device is arranged at the head of the coal cutter body. The cable penetrates from the cable guide trough near the tail of the coal cutter body, extends downwards in the middle cable guide troughs, winds around the cable pay-off device, extends upwards, returns into the corresponding cable guide trough, is led out and finally is wound on the cable take-up device. The cable of the coal cutter is changed to be arranged on the hydraulic supporting frame top beams, and the cable take-up device and the cable pay-off device of which the cable take-up and pay-off speed is synchronous with the operation speed of the coal cutter are arranged. In the operation process of the coal cutter, the cable is kept in a tensioned state all the time, and the phenomenon that the cable droops and then is buried and damaged by a falling coal wall is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a coal mining machine with the function of retracting and releasing cables. Background technique [0002] Existing shearer cables are generally arranged in the conveyor cable trough, and are passed through the cable clamps for protecting the cables. When the shearer moves repeatedly along the working face to cut coal in two directions, it will drag the cable clamp to hold the cable and move accordingly. The cable between the cable clamps is bent and suspended; at the same time, the coal wall of the working face will continuously appear large pieces of coal wall falling off when the shearer is working, which is easy to bury and destroy the cable of the shearer, and there is a particularly large safety factor. Usually, special personnel are required to follow the maintenance of the machine to eliminate the phenomenon of hanging cables buried in the coal wall, prevent...
