AI Technical Summary
During the coal cutting period, the cables of the coal mining machine are prone to wear severely due to the unit's head shift and the high frequency of coal sweeping. The cables are distilled from the trough near the fuselage, which poses safety hazards. The existing protective measures cannot effectively prevent the cable from falling into the slipper.
A comprehensive mining working surface coal mining machine cable anti-detachment device is designed, including a first vertical rod, a cross rod and a guide roller, which is fixed on the inside of the cable trough, and the guide roller is used to drive the cable to move in a certain direction to prevent the cable from falling into the slipper, and is fixed by the roller anti-detachment nut to achieve guidance and anti-falling.
Effectively avoid the direction of the cables during movement, prevent cable clamps and damage, reduce cost investment, save labor, improve production efficiency, and improve on-site safety management and control capabilities.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shearers in fully mechanized coal mining faces, and particularly relates to a cable anti - detachment device for shearers in fully mechanized coal mining faces. Background Technique
[0002] Currently, the coal cutting method in the fully mechanized coal mining face is two - way coal cutting. The unit cable needs to move synchronously with the unit. To avoid cable wear, cable clips are installed on the cable for protection, and a special cable trough plays a role in protection and guidance.
[0003] During the production process in the coal face, due to the movement of the unit head and tail, high frequency of coal sweeping, and a large amount of large coal near the machine body, the cable near the unit dragging device is easily severely worn. When the cable shows problems such as breakage and explosion - proof failure, the cable needs to be re - terminated. To avoid the situation of insufficient cable length in the working face, a certain surplus is provided when installing the working face unit cable. Since the cable length is longer than the cable trough, during the coal cutting period of the unit, the cable in the middle of the working face is overlapped and pressed, resulting in the cable height exceeding the coal - retaining plate of the cable trough. Without the guiding function of the cable trough, the cable is easily detached from the trough and falls into the scraper conveyor, and is damaged by the running scraper conveyor, posing a certain safety hazard. Content of the Utility Model
[0004] The purpose of the utility model is to provide a cable anti - detachment device for shearers in fully mechanized coal mining faces, which can prevent the cable from falling into the front scraper conveyor during the coal cutting period of the unit, play a guiding role, improve the on - site safety control ability, and ensure the integrity of the cable.
[0005] The technical solution adopted by the utility model to solve its technical problems: A cable anti - detachment device for shearers in fully mechanized coal mining faces is arranged on the inner upper edge of the cable trough, including a first vertical rod. Cross - bars are symmetrically fixed on both sides of the middle part of the first vertical rod. A round tube is sleeved on the upper part of the first vertical rod to form a guiding roller. A second vertical rod parallel to the first vertical rod is fixed below the cross - bar on one side. The first vertical rod and the second vertical rod are inserted into the gap of the baffle of the cable trough for fixation. The cross - bar abuts against the upper edge of the baffle of the cable trough to prevent it from falling, and the guiding roller is in rolling contact with the cable clip.
[0006] Further, a roller anti - detachment nut is arranged at the upper end of the first vertical rod.
[0007] Further, the height of the guiding roller is 20 cm.
[0008] The utility model has the following beneficial effects:
[0009] The cable anti - detachment device for shearers in fully mechanized coal mining faces of the utility model can effectively avoid the deviation of the cable direction during the movement process, prevent the cable from falling into the scraper conveyor and causing damage to the cable clip and the cable, reduce the cost investment, save the labor input for cable care, and improve the production efficiency.

[0013] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a cable anti - detachment device for a shearer in a fully - mechanized coal mining face with reference to the drawings.
[0014] As Figure 1 and Figure 2 shown, a cable anti - detachment device for a shearer in a fully - mechanized coal mining face is arranged on the inner upper edge of the cable trough 6, and includes a first vertical rod 1. On both sides of the middle of the first vertical rod 1, cross bars 2 are symmetrically fixed. A circular tube is sleeved on the upper part of the first vertical rod 1 to form a guide roller 3. Below one of the cross bars 2, a second vertical rod 5 parallel to the first vertical rod 1 is fixed. The first vertical rod 1 and the second vertical rod 5 are inserted into the baffle gap of the cable trough 6 for fixation. The cross bar 2 abuts against the upper edge of the baffle of the cable trough 6 to prevent it from falling backward, and the guide roller 3 is in rolling contact with the cable clip.
[0015] In this embodiment, waste φ22 round steel is used, and round steel bars with lengths of 40 cm for one piece and 10 cm for three pieces are processed respectively. The 40 - cm round steel is used as the first vertical rod 1. On both sides of its middle part, a 10 - cm round steel is welded as the cross bar 2 to form an anti - falling - backward structure. At a position 6 cm away from the 40 - cm round steel below one of the 10 - cm round steels, a 10 - cm round steel is welded as the second vertical rod 5 to form a fixing structure.
[0016] A 6 - minute iron pipe is cut into 20 - cm lengths and inserted above the 40 - cm round steel to form the guide roller 3 of the cable anti - detachment device, so that the cable clip slides along with the guide roller 3. A φ24 nut is welded on the top of the 40 - cm round steel as the roller anti - detachment nut 4.
[0017] For the cable anti - detachment device of the shearer in this embodiment, the guide roller 3 drives the cable to move along a certain direction, realizing the cable guiding and anti - detachment effects. The fixing structure and the anti - falling - backward structure can effectively prevent the cable anti - detachment device of the shearer from falling and toppling.
[0018] During use, insert the two vertical rods side by side at the bottom of the cable anti-disconnection device into the gap of the baffle of the cable trough, and the installation is completed. The cable anti-disconnection devices for shearer in the fully mechanized coal mining face are evenly arranged at five places in the middle part of the working face, and the installation quantity can be adjusted according to the actual situation. When the unit cable moves, the cable slides along the guiding roller 3, which can effectively prevent the cable from falling into the scraper conveyor.
[0019] By designing and installing the cable anti-disconnection device for shearer in the fully mechanized coal mining face, during the coal cutting period of the unit, it can prevent the cable from falling into the front scraper conveyor and being hung up, squeezed or damaged by the running scraper and large coal, improving the on-site safety control ability and ensuring the integrity of the cable.
