[0002] The subway tunnel is an important part of the urban rail transit system, mainly used to connect each subway station so that the train can run underground. The shield section of the subway refers to the part of the subway tunnel constructed by the shield method. Among them, the tunnel battery car refers to a transport vehicle moving on the track in the shield section of the subway tunnel, mainly used for personnel transportation, material or equipment handling during subway construction and maintenance.

[0003] However, during subway construction, the heavy-load transportation operation of battery cars in the subway shield section is relatively frequent. When the battery car is loading and unloading goods or personnel at the tunnel entrance, there may be mechanical failures such as brake failure of the battery car and human operation errors where the driver fails to apply the brake in time, resulting in the risk of the battery car slipping, which greatly affects the quality of goods and the safety of personnel.

[0004] Therefore, it is necessary to provide an anti-sliding car stopper to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an anti-sliding car stopper to solve the above technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0011] Further, two placement grooves adapted to the vertical stop bars are opened on the car-stopping bar, a rotating rod is rotatably arranged on the inner wall of the placement groove, and the vertical stop bar is connected to the rotating rod.

[0012] Further, a transmission cavity is opened inside the car-stopping bar, and the transmission mechanism includes:

[0013] There are two transmission rods, which are telescopically and movably arranged in the transmission cavity, and a first tooth block and a second tooth block are respectively arranged on the transmission rods;

[0014] One end of the rotating rod extending into the transmission cavity is provided with a first gear, and the first gear meshes with the first tooth block;

[0015] A linkage component is arranged in the transmission cavity and is used to drive the two transmission rods to move.

[0016] Furthermore, the linkage component includes:

[0017] A linkage rod is rotatably arranged in the transmission cavity. A second gear and a rope winding cylinder are arranged on the linkage rod, and the second gear meshes with the second tooth block;

[0018] A traction rope has one end wound and connected to the rope winding cylinder and the other end connected to the inner wall of the transmission groove.

[0019] Furthermore, a sliding groove is formed in the inner wall of the transmission cavity, a slider connected to the transmission rod is slidably arranged on the inner wall of the sliding groove, and an elastic member is arranged between the slider and the inner wall of the sliding groove.

[0020] Furthermore, wheel frames are arranged on the inner wall of the transmission cavity and the outer wall of the vehicle-blocking lever, and guide wheels are rotatably arranged on the wheel frames.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] 1. In this solution, the driving member drives the rotating shaft to rotate, and the rotating shaft will drive the vehicle-blocking lever to rotate and open. That is, the vehicle-blocking lever will block above the shield tunnel guide rail in a blocking state, which can block the battery car in the shield tunnel, prevent the risk of the battery car running away due to mechanical failures such as brake failure of the battery car or human operation errors such as the driver not taking timely braking, reduce the losses caused by failures, and can better protect goods and personnel, greatly reduce the risk of goods damage and improve the safety of the staff, play a further insurance role for goods and personnel, and thus ensure the quality of goods and the safety of personnel, with strong practicability.

[0023] 2. When the blocking rod rotates and opens, the transmission mechanism drives the vertical blocking rod to rotate. The vertical blocking rod changes from the horizontal state to the vertical state. At this time, the erected vertical blocking rod can block a larger area of the battery car, thereby improving the blocking effect and stability on the battery car, greatly avoiding large deformation and damage to the blocking rod caused by the battery car slipping, greatly reducing the risk of damage to the vehicle stopper of this application, and improving its service life and use effect; when the blocking rod rotates and closes, the vertical blocking rod gradually changes from the vertical state to the horizontal state and folds into the blocking rod, which can avoid interference when the battery car moves in the shield tunnel due to the protruding vertical blocking rod, reduce the space occupied by the vertical blocking rod, and has strong flexibility, so it can be widely promoted and used.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 - 10 , an anti-rolling vehicle stopper is arranged at the entrance of the shield tunnel 1, and includes: a fixed seat 2 arranged on the inner wall of the shield tunnel 1, a transmission groove 3 is opened on the fixed seat 2, a rotating shaft 4 is rotatably arranged on the inner wall of the transmission groove 3, and a driving member 5 for driving the rotating shaft 4 is arranged on the fixed seat 2; an anti-rolling stop bar 6 is arranged on the rotating shaft 4, and a stop post 7 matched with the anti-rolling stop bar 6 is arranged on the inner wall of the shield tunnel 1; a vertical stop bar 8 is rotatably arranged on the anti-rolling stop bar 6 and there are two of them, and a transmission mechanism 9 for driving the vertical stop bar 8 to rotate is arranged in the anti-rolling stop bar 6. In this application, the driving member 5 can adopt a matching mode of a servo motor, a speed reducer and a gear box to drive the rotating shaft 4 to rotate; and the driving member 5 adopts a wireless remote control mode to be signal-connected with the controller.

[0038] When the battery car in the shield tunnel 1 is in normal use, it will carry goods or personnel and move along the track. When the battery car in the shield tunnel 1 stops, at this time, the driving member 5 works, and the driving member 5 will drive the rotating shaft 4 to rotate. The rotating shaft 4 will drive the anti-rolling stop bar 6 to rotate and open. Finally, the anti-rolling stop bar 6 will rotate ninety degrees, that is, the anti-rolling stop bar 6 will change from the direction along the shield tunnel 1 and the guide rail to the direction perpendicular to the shield tunnel 1 and the guide rail, that is, the anti-rolling stop bar 6 will block above the guide rail of the shield tunnel 1, as Figure 3State, at this time, the other end of the vehicle-blocking lever 6 contacts the stop post 7. At this time, the vehicle-blocking lever 6 will be in a blocking state, that is, it can block the battery car in the shield tunnel 1, thereby preventing the risk of the battery car slipping due to mechanical failures such as brake failure of the battery car or human operation errors where the driver fails to apply the brake in time, reducing the losses caused by failures, and being able to better protect the goods and personnel, greatly reducing the risk of damage to the goods and improving the safety of the staff, having a further insurance effect on the goods and personnel, and thus ensuring the quality of the goods and the safety of the personnel, with strong practicability. When the battery car needs to move away, at this time, the driving member 5 drives the rotating shaft 4 and the vehicle-blocking lever 6 to rotate in the reverse direction to close, that is, the vehicle-blocking lever 6 is rotated away from the guide rail, that is, it returns to the initial state along the shield tunnel 1 and the guide rail. At this time, the battery car is not blocked and can move.

[0039] When the vehicle-blocking lever 6 rotates and opens, it will also cause the transmission mechanism 9 to work. The transmission mechanism 9 will drive the vertical blocking lever 8 to rotate, that is, the vertical blocking lever 8 rotates out of the vehicle-blocking lever 6, and the vertical blocking lever 8 will change from the horizontal state to the vertical state, as Figures 3 - 4 State. At this time, the erected vertical blocking lever 8 can block a larger area of the battery car, thereby improving the blocking effect and stability on the battery car, greatly avoiding large deformation and damage to the vehicle-blocking lever 6 caused by only blocking with the vehicle-blocking lever 6, and thus greatly reducing the risk of damage to the vehicle stopper of the present application and improving its service life and use effect. When the vehicle-blocking lever 6 rotates and closes, through the action of the transmission mechanism 9, the vertical blocking lever 8 will gradually change from the vertical state to the horizontal state, and finally the vertical blocking lever 8 will rotate and fold into the vehicle-blocking lever 6, as Figures 1 - 2 State. At this time, the storage of the vertical blocking lever 8 can be realized, which can avoid interference when the battery car moves in the shield tunnel 1 due to the protrusion of the vertical blocking lever 8, reduce the space occupied by the vertical blocking lever 8, and has strong flexibility and can be widely promoted and used.

[0040] In this embodiment, preferably, please refer to Figures 1 - 5 、 Figures 7 - 8 And Figure 10 , two placement grooves 10 adapted to the vertical blocking lever 8 are provided on the vehicle-blocking lever 6. The inner wall of the placement groove 10 is rotatably provided with a rotating rod 11, and the vertical blocking lever 8 is connected to the rotating rod 11. Before the vehicle-blocking lever 6 is opened for use, such as Figure 2 State. At this time, the vertical blocking lever 8 is folded in the placement groove 10; when the driving member 5 drives the vehicle-blocking lever 6 to rotate and open, at this time, through the action of the transmission mechanism 9, the vertical blocking lever 8 gradually rotates out of the placement groove 10, that is, rotates along the rotating rod 11, and finally as Figure 4 Shown state.

[0041] In this embodiment, preferably, please refer to Figures 5 - 10, a transmission cavity 12 is formed inside the vehicle-blocking lever 6. The transmission mechanism 9 includes: transmission rods 91, two of which are provided and are telescopically and movably arranged inside the transmission cavity 12. A first tooth block 92 and a second tooth block 93 are respectively arranged on the transmission rod 91; one end of the rotating rod 11 extending into the transmission cavity 12 is provided with a first gear 94, and the first gear 94 meshes with the first tooth block 92; a linkage member 95 is arranged inside the transmission cavity 12 and is used to drive the two transmission rods 91 to move. When the driving member 5 drives the vehicle-blocking lever 6 to rotate and open, through the cooperation of the linkage member 95, the two transmission rods 91 will be driven to move, and the moving directions of the two transmission rods 91 are opposite. When the transmission rod 91 moves, the first tooth block 92 thereon drives the first gear 94 and the rotating rod 11 to rotate, and when the rotating rod 11 rotates, the vertical blocking lever 8 will be driven to rotate.

[0042] In this embodiment, preferably, please refer to Figures 4 - 10 , the linkage member 95 includes: a linkage rod 951, which is rotatably arranged inside the transmission cavity 12. A second gear 952 and a rope winding cylinder 953 are arranged on the linkage rod 951, and the second gear 952 meshes with the second tooth block 93; a traction rope 954, one end of which is wound and connected to the rope winding cylinder 953, and the other end is connected to the inner wall of the transmission groove 3. When the driving member 5 drives the vehicle-blocking lever 6 to rotate and open, at this time, the end of the vehicle-blocking lever 6 close to the inner side wall of the transmission groove 3 will gradually move away from the transmission groove 3, as Figure 4 , the vehicle-blocking lever 6 moves away from the inner wall of the transmission groove 3 connected to the traction rope 954. When the vehicle-blocking lever 6 rotates away, the traction rope 954 inside the vehicle-blocking lever 6 will be stretched, that is, the traction rope 954 will drive the rope winding cylinder 953 and the linkage rod 951 to rotate, and at this time, the linkage rod 951 drives the two transmission rods 91 to move simultaneously through the cooperation of the second gear 952 and the second tooth block 93, and the moving directions of the two transmission rods 91 are opposite. When the driving member 5 drives the vehicle-blocking lever 6 to rotate and close, the traction rope 954 is gradually no longer stretched, and the two transmission rods 91 will also return to the initial state.

A slider 14 connected to the transmission rod 91 is slidably arranged on the inner wall of the sliding groove 13. An elastic member 15 is arranged between the slider 14 and the inner wall of the sliding groove 13. The elastic member 15 in this application is a spring. When the transmission rod 91 moves, it will drive the slider 14 to move along the sliding groove 13. When the driving member 5 drives the vehicle-blocking lever 6 to rotate and open, at this time, when the two transmission rods 91 move, they will compress the elastic member 15 through the movement of the slider 14, and when the driving member 5 drives the vehicle-blocking lever 6 to rotate and close, at this time, the resilience of the elastic member 15 will drive the transmission rod 91 to move to the initial state position.
