Description

Technical Field

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

[0002] A coal mine is a rationally excavated space created by humans when mining geological strata rich in coal. It typically includes roadways, shafts, and mining faces. Coal mine electromechanical equipment refers to mechanical and electrical equipment. Cable winding devices are used in the operation of electromechanical equipment where cables are used. However, after use, the cables need to be wound up. Most existing cable winding devices require workers to manually wind the cables onto a fixed object. This results in low work efficiency, and the cables cannot be wound in an orderly manner, affecting winding and unwinding. Furthermore, it prevents the cables from being cleaned, and the adhering substances can cause damage and corrosion to the cable surface over time.

[0003] Existing technologies, such as the Chinese authorized publication number CN218809711U, describe a cable winding device for electromechanical installation in coal mines. By controlling the activation of a second servo motor, the device drives a rotating column to rotate, which in turn drives a second rotating disk, thereby rotating the winding mechanism of the device. This achieves the purpose of quickly adjusting the winding and unwinding direction of the device. It solves the problem that when winding or unwinding, the device needs to be aligned with the first or second winding direction, and the location of the operation is constantly changing, requiring the position of the cable winding device to be checked each time, which is time-consuming and laborious, greatly reducing the efficiency of the operation. This device achieves high efficiency in use.

[0004] Other existing technologies include: CN217458248U, a cable winding device for electromechanical installation in coal mines.

[0005] CN216807592U, A cable winding device for electromechanical installation in coal mines.

[0006] CN216190005U, A cable winding device for electromechanical installation in coal mines.

[0007] However, the above-mentioned and other typical existing technologies still have certain problems in use:

[0008] 1. When this equipment is in use, the cable entanglement may generate ultra-high voltage and high-intensity power frequency electromagnetic fields, which are harmful to human health and may cause symptoms such as fatigue, weakness, headache, poor sleep, and myocardial pain. The effect of electromagnetic fields on the human body is mainly functional changes. In addition, high-frequency electromagnetic fields may also interfere with the normal operation of electronic equipment such as communication and measurement devices, and may even cause accidents. They may also generate high-frequency sparks due to induction, causing fires or explosions.

[0009] 2. The winding device is not easy to disassemble during use, which makes internal maintenance and cleaning, including handling, very inconvenient. Furthermore, the winding process is not easy to separate the components, which causes many inconveniences in winding cables and reduces the efficiency of winding cables. Utility Model Content

[0010] The purpose of this utility model is to provide a cable winding device for electromechanical installation in coal mines, so as to solve the problem mentioned in the background art that the winding device may generate ultra-high voltage and high-intensity power frequency electromagnetic fields when in use, which may harm human health, interfere with the normal operation of electronic equipment such as communication and measurement, or even cause accidents.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a cable winding device for electromechanical installation in coal mines, comprising a base assembly, a base plate on the top of the base assembly, a vertical plate on the top of the base plate, the base plate and the vertical plate being fixedly connected, two disassembly wheels on the side of the vertical plate, a rotating wheel between the two disassembly wheels, an EMI filter on the side of the disassembly wheels, a limit rod on the side of the EMI filter, and a metal shielding sleeve on the outside of the rotating wheel.

[0013] As a preferred embodiment of this utility model, a connecting rod is provided on the side of the second gear, and the second gear is fixedly connected to the connecting rod.

[0014] As a preferred embodiment of this utility model, the metal shielding sleeve has an inlet / outlet port inside, and two cables are provided inside the inlet / outlet port.

[0015] As a preferred embodiment of this utility model, a mounting block is provided on the top of the base plate, a second screw is provided inside the mounting block, and a threaded sleeve is provided outside the second screw.

[0016] As a preferred embodiment of this utility model, a fixing block is provided at the bottom of the metal shielding sleeve, and the metal shielding sleeve is fixedly connected to the fixing block. There are two fixing blocks.

[0018] As a preferred embodiment of this utility model, the mounting block is provided with a locking head on its side, the mounting block is rotatably connected to the locking head, and there are two locking heads.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model utilizes an EMI filter to achieve electromagnetic compatibility, eliminating electromagnetic interference and realizing electromagnetic compatibility. The metal shielding sleeve induces eddy currents of the same frequency on its outer surface, thereby consuming the energy of high-frequency interference. Secondly, the eddy currents will also generate a new magnetic field. According to Lenz's law, its direction is exactly opposite to the direction of the interference source, thus canceling out part of the energy of the interference magnetic field, thereby protecting the circuit inside the electromagnetic shielding layer from the influence of high-frequency interference magnetic fields.

[0021] 2. This utility model utilizes a screw-locking head to extend and retract the second screw upwards. When the first and second screws come into contact, they can be locked together using a threaded sleeve, which facilitates the disassembly of the metal shielding sleeve and greatly facilitates the removal and cleaning of the internal rotating wheel. The drive motor drives the gear meshing to efficiently wind the cable. Attached Figure Description
