It includes equipment such as mine hoists and hoisting winches used for hoisting coal, gangue, personnel, and materials; equipment such as scraper conveyors, belt conveyors, and mine locomotives used for transporting coal, personnel, and materials on the surface or underground; equipment such as main fans and local fans used for mine ventilation and gas emission; and equipment such as mine pumps and drainage pipes used for mine drainage.

[0003] A search revealed Chinese Patent Publication No. CN 118560990 A, which discloses a continuous reversing device for coal mine electromechanical transportation. The device includes an arc-shaped conveyor body, a conveyor frame, a rotating drive mechanism at the bottom of the conveyor frame, and at least three conveying rollers arranged circumferentially on the upper part of the conveyor frame. All the conveying rollers are fitted with an arc-shaped conveyor belt, and the outermost conveying roller is connected to a conveyor motor.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a continuous reversing device for electromechanical transportation in coal mines. For example... Figure 1As shown, the device includes a bottom mounting bracket 1. A central force-bearing plate 2 is fixedly installed in the middle of the upper surface of the bottom mounting bracket 1. An arc-shaped support plate 5 is fixedly installed at one end of the central force-bearing plate 2. A rotating shaft 18 is rotatably installed in the middle of the upper surface of the arc-shaped support plate 5. A driven spur gear 10 is fixedly sleeved in the middle of the rotating shaft 18. A driving spur gear 8 is engaged with the driven spur gear 10 through the teeth on one side of its outer circumferential surface. The middle of the driving spur gear 8 is fixedly sleeved on the outside of the output shaft at the top of the motor 9. The side of the motor 9 is fixedly installed in the middle of one end of the central force-bearing plate 2.

[0024] Please see Figures 2-4 A limiting vertical rod 15 is fixedly installed on the inner wall of the power groove in the middle of the upper surface of the middle force plate 2. A semi-circular sliding plate is slidably sleeved on the middle of the upper surface of the limiting vertical rod 15. A fixing rod 12 is fixedly installed on the upper surface of the semi-circular sliding plate. There are four fixing rods 12. The tops of the four fixing rods 12 are evenly arranged below the top moving plate 3. The bottoms of the fixing rods 12 are all arranged on the upper surface of the semi-circular sliding plate that slides on the surface of the limiting vertical rod 15. The fixing rods 12 support the bottom of the top moving plate 3 to prevent the top moving plate 3 from tilting when it drives the upper structure to move, thereby increasing its stability.

[0025] Please see Figure 2 A top moving plate 3 is fixedly attached to the top of the fixed rod 12. A groove is fixedly provided on the upper surface of the top moving plate 3. A limiting crossbar 20 is fixedly provided in the middle of the groove. A slider 11 is slidably sleeved in the middle of the limiting crossbar 20. The slider 11 slides on the surface of the limiting crossbar 20, restricting the movement trajectory of the slider 11 and the top crossbar 13 above. A top crossbar 13 is fixedly provided on the top of the slider 11. The lower surface of the top crossbar 13 is slidably connected to the upper surface of the top moving plate 3. An arched fixing frame 17 is fixedly provided on the upper surface of the top moving plate 3. A turning plate 6 is fixedly provided on the top of the fixing frame 17 through a vertical shaft. The turning plate 6 is set in a "+" shape and is located above the pulley. The "+" shaped turning plate 6 can transport the coal above in four directions to meet the movement requirements of different angles.

[0026] Please see Figure 3 A pulley 14 is rotatably mounted on one end of the upper surface of the top horizontal plate 13. The pulley 14 supports the middle of the pull rope 3. The pull rope 4 causes the pulley 14 to move the top horizontal plate 13 back and forth. The middle of the outer circumference of the pulley 14 is connected to the inner side of the pull rope 4. The pull rope 4 is located in the middle of the outer side of the pulley 7, the pulley 14 and the auxiliary pulley 19. A fixing block 16 is fixedly mounted on one end of the upper surface of the top moving plate 3. The two ends of the inner side of the fixing block 16 are fixedly connected to the two ends of the pull rope 4. By fixing the two ends of the pull rope 4 to one side of the fixing block 16, the length of the pull rope is fixed. Under the rotation of the power, the pull rope 4 pulls the pulley.

[0027] Please see Figure 3 A secondary pulley 19 is rotatably mounted on the edge of the upper surface of the top moving plate 3. There are four secondary pulleys 19, which are rotatably mounted at the four corners of the upper surface of the top moving plate 3. The middle of the outer side of each of the four secondary pulleys 19 is connected to the pulley 7 via a pull rope 4. The four identical secondary pulleys 19 are mounted above the top moving plate 3, so that the top moving plate 3 can move smoothly under the action of the pull rope 4. At the same time, the four secondary pulleys 19 are used to tension the pull rope 4.

[0028] Please see Figure 2 and Figure 3 Two pulleys 7 are installed at the center of the outer circumference of the auxiliary pulley 19 via a pull rope 4. Both pulleys 7 are located inside the pull rope 4. The rotating shaft 18 at the center of each of the two pulleys 7 is equipped with a driven spur gear 10. The driving spur gear 8 outside the two driven spur gears 10 is equipped with two motors 9. Two motors 9 are installed on both sides of the force plate 2 at the center. When the two motors 9 rotate in sequence, the two pulleys 7 apply tension to the pull rope 4 in different directions. The center of the pulley 7 is fixedly sleeved on the top of the rotating shaft 18.

[0029] The implementation principle of a continuous reversing device for coal mine electromechanical transportation according to an embodiment of this application is as follows: When the coal above the steering plate 6 needs to be turned during use, one of the motors 9 is started as power, and the rotating shaft 18 is rotated through the cooperation of spur gears. The rotating shaft 18 drives the pulley 7 to rotate. When the pulley 7 rotates, it pulls the auxiliary pulley 19 through the pull rope 4. Since the length of the pull rope 4 is fixed and one side of the middle is supported by the pulley 14, when the pulley 7 at the left end rotates clockwise as power, the pull rope 4 pulls the top horizontal plate 13 forward. When the pulley 7 at the left end rotates counterclockwise as power, the pull rope 4 moves in the opposite direction, and at the same time, the top moving plate 3 moves to the right. When the pulley 7 at the right end rotates clockwise as power, it is pulled by the pull rope 4, and the top moving plate 3 moves to the left while the top horizontal plate 13 moves backward. The rotating plate 6 above moves in four directions, realizing the continuous turning effect of coal mine electromechanical transportation.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
