Abstract
Description
Technical Field
[0001] The utility model relates to the field of coal mining, in particular to a coal mining device with a cable self-moving function. Background Art
[0002] In fully mechanized mining operations in underground coal mines, shearers are key equipment for coal mining, and their proper operation is directly related to the mine's production efficiency. However, in practice, the management and use of shearer cables face numerous challenges, seriously impacting the mine's overall production efficiency.
[0003] First, shearing machine cables are prone to slipping or getting stuck in the cable trough, preventing them from moving smoothly. This not only affects the normal operation of the shearer but can also cause equipment failure or downtime, further delaying coal mine production. For example, when a cable becomes stuck, the shearer may not operate properly, requiring downtime for maintenance, increasing production costs and time. Furthermore, cable slippage can lead to an unstable connection between the cable and the equipment, further affecting the shearer's operating efficiency.
[0004] Secondly, traditional cable management methods typically require dedicated personnel to ensure the safety and smooth operation of the cables. However, this approach carries significant safety risks. When workers come into close contact with cable troughs, accidents can easily occur, such as being hit by moving equipment or accidentally breaking cables, endangering personal safety. For a long time, this reliance on manual supervision has not only increased labor costs but also made it difficult to eliminate safety risks.
[0005] Furthermore, frequent cable jams or slippage can damage the cable, increasing repair costs and financial losses. Damaged cables not only require time-consuming replacement and repair, but can also cause production lines to stall, leading to even greater financial losses. Utility Model Content

This device can realize cable retraction and release, prevent cable slippage or jamming, improve the working efficiency of the coal mining machine, and reduce the dependence on manual supervision, thereby reducing safety hazards and operating costs. Through effective cable management, it can ensure the normal operation of the coal mining machine, improve the production efficiency of the coal mine, reduce economic losses, and promote the sustainable development of the coal mine.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] refer to Figure 1 As shown, the utility model discloses a coal mining device with a cable self-moving function, comprising a coal mining machine 1, a skid trolley 2, a scraper conveyor body, a trough tail pulley 6, a trough head pulley 7, a cable 10, a cable trough 5 and a traction rope; the coal mining machine 1 is installed on the working surface, and the two sides of the scraper conveyor body are respectively the scraper conveyor tail 3 and the scraper conveyor head 4; the trough tail pulley 6 is installed on the scraper conveyor body and is located on one side of the scraper conveyor tail 3; the trough head pulley 7 is installed on the scraper conveyor body and is located on one side of the scraper conveyor head 4; the cable trough 5 is installed on the upper part of the scraper conveyor body; The skid trolley 2 is mounted on the scraper conveyor body. A tail pulley 8 is provided at one end of the skid trolley 2, and a head pulley 9 is provided at the other end. One end of the traction rope passes over the tail pulley 6 and connects to the shearer 1. The other end of the traction rope passes over the head pulley 7 and the tail pulley 8 and connects to the scraper conveyor head 4. The movement of the shearer 1 drives the traction rope, causing the skid trolley 2 to move between the tail pulley 6 and the head pulley 7. One end of the cable 10 is connected to the shearer 1, while the other end passes over the head pulley 9, enters the working face, and connects to a power source. The cable 10, connected to the power source, provides power to the shearer 1. When the shearer 1 cuts coal downward, it pulls the wire rope 11 downward. The wire rope 11, driven by the tail pulley 6, head pulley 7, and tail pulley 8, drives the skid trolley 2 downward, simultaneously driving the cable 10 downward. The cable 10 is placed in the cable trough 5 to prevent frequent bending and damage. When the coal mining machine 1 cuts coal upward, it pulls the cable 10 to move upward. The cable 10 is stacked in the cable trough 5 through the skid trolley 2, and at the same time drives the wire rope 11 to move.
[0018] In this embodiment, the traction rope is a steel wire rope 11; the sliding vehicle 2 is a prior art, and the side of the sliding vehicle 2 in the prior art is a right-angled type. In this embodiment, the side of the sliding vehicle 2 is an arc-shaped structure. The arc-shaped structure of the sliding vehicle 2 can minimize the friction between the sliding vehicle 2 and the cable trough 5, reduce the damage of the sliding vehicle 2 to the cable 10, and improve the safety of the cable 10.
[0019] The scraper conveyor tail 3 is the tail part of the scraper conveyor, located at the terminal position of the coal mining working face; the scraper conveyor is used to transport coal from the working face where the coal mining machine 1 is located to the next link of the transportation system, and the scraper conveyor tail 3 is the end point of this transportation path.
[0020] The scraper conveyor head 4 serves as the power source and starting end of the scraper conveyor. The scraper conveyor head 4 carries the coal flow and can always maintain stable transportation during the transmission process to prevent the coal flow from being blocked or derailed during the coal mining process; the cable 10 is arranged in the cable trough 5 and connected to the coal mining machine 1; when the coal mining machine 1 cuts coal downward, the wire rope 11 is released, so that the cable 10 slides downward under the action of gravity and is placed in the cable trough 5; when the coal mining machine 1 cuts coal upward, it moves upward by pulling the cable 10, thereby driving the wire rope 11 to move upward together; due to the synchronous movement of the skid 2 and the coal mining machine 1, the cable 10 is retracted and released in the cable trough 5, which prevents the cable 10 from slipping or getting stuck outside the cable trough 5, thereby ensuring the coal mining efficiency; wherein, the cable trough 5 can be a round tube with a hollow interior.
[0021] In the above embodiment, the tail pulley 6, head pulley 7, tail pulley 8, and head pulley 9 are all fixed pulleys. These pulleys effectively guide the movement of the cable 10 and wire rope 11, ensuring that the cables move synchronously with the shearer 1. Furthermore, the fixed pulleys maintain a certain tension in the wire rope 11 and cable 10 during traction by the shearer 1, preventing the cable 10 from sliding down or getting stuck. Furthermore, the fixed pulleys evenly distribute the pulling force of the traction rope and cable 10 across the skid trolley 2 and the cable trough 5, achieving stable movement.
[0022] The above solution shows that by installing the cable self-moving device, electromechanical accidents caused by cable problems can be effectively avoided, thereby improving the coal mining machine's operating rate. By tightening the wire rope 11 driven by the coal mining machine 1, the coal mining machine cable 10 can be ensured to move uniformly and neatly within the cable trough 5. At the same time, most of the tension is applied to the wire rope 11, reducing the tension on the cable during operation of the coal mining machine 1. At the same time, personnel no longer need to enter the front of the bracket to guard the cable, thus eliminating safety hazards.
