Description

Technical Field

[0001] The utility model relates to the technical field of coal mine electromechanical equipment, in particular to a coal mine electromechanical cable hanging structure. Background Art

[0002] Coal mine electromechanical equipment is the basic equipment for coal mine operation. During the coal mining and production process, a large number of coal mine mechanical equipment, electrical equipment and electromechanical equipment are required to operate, which mainly include lifting equipment, ventilation equipment, compressed air equipment, drainage equipment, mining equipment, transportation equipment, etc. The transportation and transmission equipment of coal mines is very important, which is related to the stability and safety of coal mine transportation. Coal mine electromechanical equipment requires electricity in the well, so the power supply cable needs to be hung in the well through a hanging structure.

[0003] The existing hanging structure is generally a metal ring fixed on the wall inside the well, so that the cable passes through the metal ring for hanging. However, the applicant found that when dragging the cable for wiring, it is easy to cause friction between the cable and the metal ring, causing wear. Moreover, the metal ring is only fixed on the wall. The vibration generated during mining in the well is transmitted to the metal ring, which is easy to loosen the metal ring. For this reason, we propose a coal mine electromechanical cable hanging structure. Utility Model Content
