[0022] The following is combined with Figures 1 to 5 The utility model is further described.

[0023] The utility model discloses a coal mine material turning device, comprising a turning platform 1, a discharge hole 2 is provided on the top of the turning platform 1, two mounting plates 4 are arranged in the discharge hole 2, the spacing between the two mounting plates 4 can accommodate at least two mine cars, mounting grooves 3 are provided on two opposite inner walls of the discharge hole 2, rotating mechanisms are installed on the inner walls of the two mounting grooves 3 that are far away from each other, the two rotating mechanisms are used to rotate the two mounting plates 4 respectively, vehicle passing holes 25 are provided on the sides of the two mounting plates 4 that are close to each other, track plates 5 are fixedly installed on the sides of the two mounting plates 4 that are close to each other, two turning rails 6 are fixedly installed on the top of the track plate 5, two fixed rails 15 are fixedly installed on the top of the turning platform 1, and the two fixed rails 15 correspond to the positions of the two turning rails 6 respectively. Through the setting of the fixed rails 15, the mine car can first pass through the fixed rails 15, then enter the turning rails 6, and finally move out of the turning rails 6 and enter the fixed rails 15, so that a plurality of mutually connected mine cars can be unloaded, and a vehicle fixing mechanism is installed on the track plate 5;

[0024] By means of the above structure: the mine car located on the flip track 6 can be fixed by the vehicle fixing mechanism, so as to facilitate its later flipping stability. During flipping, the two mounting plates 4 can be driven to rotate by the rotating mechanism, thereby causing the mine car located in the two mounting plates 4 to rotate. After the mine car flips 180 degrees, the material falls from the mine car, which is convenient for material discharge, and enters the material storage bin after passing through the unloading hole 2 and the warehouse mouth, so that multiple mine cars can be unloaded.

[0025] The rotating mechanism includes a flip motor 12 fixedly installed on the inner wall of the mounting groove 3 away from the track plate 5, a flip shaft 13 is fixedly installed on the output end of the flip motor 12, a flip gear 14 is fixedly installed on the end of the flip shaft 13 away from the flip motor 12, and an inner gear ring 10 is fixedly installed on the side of the mounting plate 4 close to the flip motor 12, and the inner gear ring 10 is meshed with the flip gear 14.

[0026] In this embodiment, when flipping is required, the two flip shafts 13 can be rotated by starting the two flip motors 12, thereby rotating the two flip gears 14. The rotation of the two flip gears 14 drives the two mounting disks 4 to rotate through the two inner gear rings 10, thereby rotating the mine car located in the two mounting disks 4. The setting of the two flip motors 12 facilitates the flipping of the mine car.

[0027] Specifically, the rotating mechanism also includes two arc-shaped limit blocks 11 fixedly mounted on the inner wall of the mounting groove 3. The two arc-shaped limit blocks 11 are provided with arc-shaped limit grooves 24 on the sides close to the mounting plate 4. The sides of the inner gear ring 10 close to the flip motor 12 are rotatably mounted in the two arc-shaped limit grooves 24.

[0028] In this embodiment, the inner gear ring 10 can be limited by the provision of the arc-shaped limiting groove 24, so that it can only rotate but cannot move forward or backward.

[0029] Specifically, the vehicle fixing mechanism includes a plurality of arc rods 8 arranged between two mounting plates 4, the distance between two arc rods 8 close to each other is smaller than the length of the mine car, the plurality of arc rods 8 are arranged at equal intervals, vertical rods 7 are fixedly installed at both ends of the plurality of arc rods 8, connecting plates 9 are fixedly installed at the bottom ends of the plurality of vertical rods 7 located on the same side, and two extrusion assemblies are installed on the top of the turning table 1, and the extrusion assemblies are connected to the sides of the two adjacent vertical rods 7.

[0030] Specifically, a spring 22 is sleeved on the vertical rod 7, and the top and bottom ends of the spring 22 are respectively fixedly installed on the sides of the track plate 5 and the connecting plate 9 that are close to each other. The arrangement of the spring 22 facilitates the track plate 5 to return to its original state after displacement. The track plate 5 is provided with a plurality of sliding holes, and the plurality of vertical rods 7 are respectively slidably installed in the plurality of sliding holes. The arrangement of the sliding holes facilitates the positioning of the vertical rods 7.

[0031] Specifically, the arc rod 8 and the vertical rod 7 are arranged corresponding to the position of the vehicle through hole 25; two baffle plates 26 are installed on the top of the turning table 1, and the two baffle plates 26 are staggered with the positions of the arc rod 8 and the vertical rod 7.

[0032] In this embodiment, by providing the baffle plate 26 , the materials scattered during the overturning process of the mine car can enter the discharge hole 2 better.

[0033] Specifically, the extrusion assembly includes two hydraulic cylinders 23 fixedly mounted on the top of the turning table 1. The hydraulic cylinder used in the present application is equipped with an oil supply device. A moving ring 16 is fixedly mounted on the output end of the two hydraulic cylinders 23. The moving ring 16 is coaxially arranged with the mounting plate 4. An annular groove 17 is provided on the inner wall of the moving ring 16. Two annular rotating blocks 18 are rotatably mounted in the annular groove 17. The advantage of such a setting is that when the mounting plate 4 rotates, the mounting plate 4 will drive the annular rotating blocks 18 to rotate in the annular groove 17, so that avoidance can be performed. The sides of the two annular rotating blocks 18 that are close to each other are fixedly mounted with connecting rods 19, and the ends of the two connecting rods 19 that are close to each other are fixedly mounted with moving rods 20. Two moving holes are provided on the side of the mounting plate 4. The two moving rods 20 respectively penetrate the two moving holes and are rotatably mounted with rotating rods 21. The bottom ends of the two rotating rods 21 are respectively rotatably connected to the sides of the two adjacent vertical rods 7.

[0034] In this embodiment, when fixing the mine car, by starting the hydraulic cylinder 23, the output shaft of the hydraulic cylinder 23 is stretched to make the two moving rings 16 approach each other, and the two moving rings 16 approach each other and move the annular rotating block 18 and the connecting rod 19, thereby moving the moving rod 20, thereby rotating the rotating rod 21, and the rotation of the rotating rod 21 causes the vertical rod 7 connected to the rotating rod 21 to move downward, thereby causing the connecting plate 9 to move downward, and the movement of the connecting plate 9 drives the remaining vertical rods 7 to move downward, thereby causing multiple arc rods 8 to move downward, pressing the mine car between the two mounting plates 4 onto the two flipping tracks 6 to keep it stable during the flipping process.

[0035] The working principle and use process of the utility model are as follows: when in use, the turning table 1 is arranged above the material storage bin, and the discharge hole 2 corresponds to the bin opening of the material storage bin. The fixed rail 15 and the turning rail 6 are arranged to allow the coal mine car to pass through. When the mine car loaded with materials enters between the two mounting plates 4, the hydraulic cylinder 23 is started at this time, and the output shaft of the hydraulic cylinder 23 is stretched to make the two moving rings 16 approach each other. The two moving rings 16 approach each other and move with the annular rotating block 18 and the connecting rod 19, thereby making the moving rod 20 move, so that the rotating rod 21 rotates, and the rotating rod 21 rotates so that the vertical rod 7 connected to the rotating rod 21 moves downward, so that the connecting plate 9 moves downward, and the connecting plate 9 moves to drive the remaining vertical rods 7 to move downward, so that the multiple arc rods 8 move downward, and the mine car between the two mounting plates 4 is pressed against the two turning rails 6 to keep it stable during the turning process;

[0036] After the mine car is clamped, the two flip shafts 13 can be rotated by starting the two flip motors 12, thereby rotating the two flip gears 14. The two flip gears 14 rotate through the two inner gear rings 10 to drive the two mounting plates 4 to rotate, thereby rotating the mine car located in the two mounting plates 4. After the mine car is flipped 180 degrees, the material falls from the mine car, passes through the unloading hole 2 and the warehouse mouth and enters the material storage bin, thereby completing the flipping and unloading. Then the output shafts of the two flip motors 12 rotate in the opposite direction, causing the two flip shafts 13 to rotate in the opposite direction, which can return the mine car to its original position, and then cause the output end of the hydraulic cylinder 23 to contract, thereby restoring the vertical rod 7 and the arc rod 8 to their original state, and the mine car can continue to pass, which is convenient for flipping other mine cars later.

[0037] The above are only preferred embodiments of the utility model, and are not intended to limit the utility model in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
