[0002] Mine cars used in underground coal mines are special transportation tools designed specifically for transporting coal, gangue, materials, equipment, etc. in mine roadways.
[0003] Existing mine cars used in underground coal mines are usually towed by a tractor or towing equipment for movement. When the connection between the mine car and the towing equipment fails, or the towing equipment itself fails, the movement speed of the mine car is difficult to control underground. Especially in steep slope areas, when the mine car disconnects from the towing equipment, it may cause the mine car to slide, and with the heavy objects carried, it generates a high acceleration, easily resulting in safety accidents such as derailment of the mine car. Moreover, installing a braking system on existing mine cars has a high cost, and existing mine cars usually do not have a braking system, making it difficult to stop a mine car that has lost speed, posing a threat to the safety of underground equipment and personnel.

Specific embodiments
[0022] To better explain the present invention for easier understanding, the technical solutions and effects of the present invention will be described in detail below in conjunction with the attached Figures 1-3 drawings through specific embodiments.
[0023] This embodiment discloses a mine car transportation blocking device for use underground in coal mines, including a mounting member 1, a rail 2, a fixing bracket 3, a rotating plate 4, an electric push rod 5, a moving bracket 6 and a swing rod 7; both front and rear sides of the upper end surface of the mounting member 1 are fixedly connected to the rail 2 to ensure the stability of the mounting member 1 and enable the entire device to better withstand the impact force from the mine car; the fixing bracket 3 is arranged at one end of the mounting member 1 and between the two rails 2, the rotating plate 4 is rotatably connected to the fixing bracket 3, the fixed end of the electric push rod 5 is connected to one side of the fixing bracket 3, the moving bracket 6 is slidably connected to the mounting member 1 along the direction of the rail 2 and is arranged on the right side of the fixing bracket 3, and both front and rear sides of the moving bracket 6 are rotatably connected to the side edges of the rotating plate 4 through the swing rod 7. The length of the swing rod 7 is less than the length of the swing rod 7 from the connection point on the rotating plate 4 to the fixing bracket 3 to prevent the rotating plate 4 from rotating too large an angle and being unable to block the mine car; the telescopic end of the electric push rod 5 is connected to the moving bracket 6, and the operating direction of the electric push rod 5 is the same as the direction of the rail 2. By the telescoping of the electric push rod 5, the erection and lowering of the rotating plate 4 are controlled, thereby blocking the out-of-control mine car.
[0024] Furthermore, the device further includes a support plate 8, a baffle 9, a connecting rod 10 and a compression spring 11. The two support plates 8 are respectively fixedly connected to the front and rear sides of the upper part of the rotating plate 4. The two connecting rods 10 are respectively slidably connected to the support plates 8. The baffle 9 is fixedly connected to the right ends of the two connecting rods 10. The compression spring 11 is arranged between the right sides of the two support plates 8 and the baffle 9 and is sleeved on the connecting rod 10; the setting of the support plate 8 enables the connecting rod 10 to slide relatively, realizing the buffering effect of the compression spring 11; the baffle 9 is arranged parallel to the right end face of the rotating plate 4, and when the baffle 9 is forced to move, it will not be blocked by the right end face of the rotating plate 4; the end size of the connecting rod 10 is larger than the size of the connection hole with the support plate 8 to prevent the connecting rod 10 from falling off the support plate 8.
[0025] In addition, in order to further restrict the movement of the mine car, the device further includes a connecting plate 12, a rotating table 13, a connecting frame 14, a rotating member 15 and a torsion spring 16. The connecting plate 12 is fixedly connected to the right side of the mounting member 1 between the rails 2. The rotating table 13 is rotatably connected to the right side of the upper end surface of the connecting plate 12. The connecting frame 14 is arranged on the upper end surface of the rotating table 13. The rotating member 15 is rotatably connected to the connecting frame 14. Both the front and rear sides of the lower part of the rotating member 15 are connected to the connecting frame 14 through the torsion spring 16. A plurality of strip-shaped grooves are evenly distributed on the surface of the rotating member 15. A clamping block (not shown in the figure) is detachably arranged at the connection between the rotating table 13 near the end of the connecting frame 14 and the connecting plate 12 to prevent the relative movement between the rotating table 13 and the connecting plate 12. By rotating the rotating table 13, the direction of the rotating member 15 is adjusted to release the one-way restriction on the mine car. When rotation is required, the clamping block is removed, and then the rotating table 13 can be rotated.
[0026] When the utility model is not in use, the electric push rod 5 is in the extended state, so that the whole device can not exceed the height of the rail 2 and does not affect the normal passage of the roadway. When in use, the mine car used in the coal mine moves on the rail 2. When the speed of the mine car is too fast and it is difficult to brake, the electric push rod 5 is started. The telescopic end of the electric push rod 5 starts to contract and pulls the moving frame 6 to move. The movement of the moving frame 6 makes the swing rod 7 gradually stand up and push up the rotating plate 4 upward. The rotating plate 4 rotates on the fixed frame 3, driving the support plate 8, the baffle 9, the connecting rod 10 and the compression spring 11 to move forward until the electric push rod 5 finishes contracting, so that the baffle 9 is tangentially parallel to the rail 2 and thus faces the mine car directly. When the mine car moves to contact with the baffle 9, the baffle 9 slides on the support plate 8 through the connecting rod 10 and compresses the compression spring 11 at the same time, thereby providing a buffering force for the mine car to avoid damage to the car body caused by the sudden stop of the mine car due to excessive speed. When the mine car is blocked at the current position, the rotating member 15 is clamped under the action of the torsion spring 16 at the bottom of the mine car to form a one-way restriction on the mine car, so that the stopped mine car cannot move in the reverse direction. The mine car is blocked at the current position by the baffle 9 and the rotating member 15 and waits for the maintenance personnel to repair it. When the mine car needs to pass normally, the clamping block is removed. The rotating member 15 is rotated by the cooperation of the connecting frame 14 and the rotating table 13. The rotating table 13 rotates to change the orientation of the rotating member 15 and change the one-way restriction state of the rotating member 15. The telescopic end of the electric push rod 5 extends, controlling the moving frame 6 to reset. The movement of the moving frame 6 makes the swing rod 7 rotate downward to control the rotating plate 4 to rotate to be flush with the rail 2, so that the mine car can move normally on the rail 2.
