Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying device for electromechanical installation in coal mines. Background Technology

[0002] Coal mine electromechanical engineering is an applied technology field that combines mechanical engineering and electrical engineering in the coal mining industry. It mainly covers the application of various mechanical equipment and electrical devices in underground and surface production systems of coal mines, including the design, selection, installation, commissioning, operation, maintenance, technical transformation, and safety management of these devices, so as to ensure that all aspects of mining, transportation, ventilation, drainage, and power supply in the coal mining process can be carried out safely and efficiently.

[0003] In the fields of coal mining, coal transportation, and underground tunneling, such as coal mining operations, a large number of electromechanical equipment, such as coal mining machines, scraper conveyors, and transfer machines, are required to transmit power and signals through cables. This is where coal mine electromechanical installation cable laying devices are used. Through cable racks, cables can be laid in an orderly manner near the coal mining face to prevent them from being crushed, collided with, or buried by coal blocks by coal mining equipment.

[0004] Currently, existing cable erection devices for coal mine electromechanical installations use anchor bolts to fix the columns to a solid ground. Before installing the anchor bolts, it is necessary to dig a suitable foundation pit to ensure that the bolts have sufficient burial depth to provide stable support for the cables. However, during the erection and laying process, the surface of the cables cannot be smoothed and tidied, resulting in bending and twisting. This causes the cables to become entangled, leading to additional compression, friction, and stretching of the outer insulation material and internal conductors, which in turn causes cracks and damage to the insulation layer, thereby increasing the risk of short circuits. Utility Model Content
