Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0040] like Figures 1 to 4 As shown, an embodiment of the utility model provides a vehicle blocking device, which includes a plurality of vehicle blocking assemblies 10 and a linkage assembly 20. The plurality of vehicle blocking assemblies 10 are arranged at intervals along the extension direction of the track 100. The vehicle blocking assembly 10 includes a vehicle blocker 11, and the vehicle blocker 11 has a vehicle blocking end 111 and a sinking end 112 that are relatively arranged, and the vehicle blocker 11 can swing relative to the track 100. The vehicle blocker 11 has a vehicle blocking state and an avoidance state that are relatively arranged. When the vehicle blocker 11 is in a natural state, the vehicle blocker 11 is in a vehicle blocking state, and the vehicle blocking end 111 is tilted in the middle of the track 100, and the vehicle blocking end 111 protrudes from the top of the track 100, and the tilting direction of the vehicle blocking ends 111 of the plurality of vehicle blocking assemblies 10 is the same. When the vehicle blocker 11 is forced to switch to the avoidance state, the vehicle blocker 11 is lower than the top of the track 100. The linkage assembly 20 is connected to the plurality of vehicle blocking assemblies 10 in sequence, and the linkage assembly 20 can enable the plurality of vehicle blocking devices 11 to swing synchronously between the vehicle blocking state and the avoidance state.

[0041] Applying the technical solution of the present application, a plurality of car blocking assemblies 10 are arranged at intervals along the extension direction of the track 100, and the car blocking assembly 10 has a car blocker 11, and the car blocker 11 has a car blocking end 111 and a sinking end 112. When the car blocker 11 is in a natural state, the car blocking end 111 of the car blocker 11 is tilted, and the tilt angles of the car blocking ends 111 of the plurality of car blockers 11 are the same, and the plurality of car blockers 11 cooperate to block the mine car to prevent the mine car from running away. The linkage assembly 20 can connect the plurality of car blocking assemblies 10, and the staff can control the plurality of car blockers 11 to switch between the car blocking state and the avoidance state at the same time through the linkage assembly 20. Such arrangement can reduce the work intensity of the staff, and then can ensure the speed of the mine car running, and improve the efficiency of the mine car transportation. And the tilt directions of the car blocking ends 111 of the plurality of car blockers 11 are the same. With such arrangement, when the mine car moves upward normally, the bottom of the mine car abuts against the blocking end 111 of the blocking device 11, and the bottom of the mine car can apply force to the blocking device 11, so that the blocking device 11 swings, thereby ensuring that the mine car can move upward normally.
