Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle blocking mechanisms, specifically relating to an automatically retractable tank track vehicle blocking mechanism. Background Technology

[0002] Vehicle braking mechanisms, also known as vehicle stoppers, use mechanical, electric, or hydraulic drives to bring vehicle-stopping components (such as wheel stops, blocks, and rail clamps) into contact with the vehicle wheels or rails, forming a physical block or clamp, thereby braking or positioning the vehicle.

[0003] When mine cages are used, tracks are installed inside the cage, and then a car-stopping mechanism is installed at the bottom of the tracks. This prevents mine vehicles from slipping, veering, or overtaking when they travel on the tracks, ensuring the safety and efficiency of transportation operations. However, when installing the car-stopping mechanism at the bottom of the tracks, space needs to be left for its installation. But the space left at the bottom of the tracks varies, which means that the top of the car-stopping mechanism's mounting base cannot be connected to the track. This requires adding pads at the bottom of the car-stopping mechanism, which greatly increases the installation time. Utility Model Content

[0004] The purpose of this utility model is to provide an automatically retractable tank-mounted rail-mounted vehicle-stopping mechanism, aiming to solve the problem in the prior art where, when the vehicle-stopping mechanism is installed at the bottom of the rail, an installation space needs to be left at the bottom of the rail. However, the installation space left at the bottom of the rail varies, resulting in the top of the mounting base of the vehicle-stopping mechanism not being able to connect with the rail. This requires the addition of a pad at the bottom of the vehicle-stopping mechanism, which greatly increases the installation time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatically retractable tank-mounted rail anti-vehicle mechanism, comprising a mounting base, a hydraulic cylinder mounted on the top of the mounting base, a connecting rod mounted on the top of the mounting base, anti-vehicle blocks rotatably connected to the surface of the connecting rod, a pull rod rotatably connected to the bottom of the anti-vehicle blocks, the pull rod being connected to the telescopic end of the hydraulic cylinder, the two anti-vehicle blocks being able to rotate in opposite directions with the mounting base via the pull rod and the hydraulic cylinder, a tank-mounted rail mounted on the top of the mounting base, a support base connected to the bottom of the mounting base, a bidirectional threaded rod rotatably connected to the inside of the support base via a bearing, a threaded sleeve threadedly connected to the surface of the bidirectional threaded rod, a first recess connected to the top of the threaded sleeve, a support rod rotatably connected to the inside of the first recess, a second recess rotatably connected to the end of the support rod, the second recess being connected to the bottom of the mounting base, and a control motor mounted on the side wall of the support base.

[0006] In a preferred embodiment of the automatically retractable tank track braking mechanism of this utility model, the bottom end of the threaded sleeve is fitted with the inner wall of the support base.

[0007] As a preferred embodiment of the automatically retractable tank track anti-vehicle mechanism of this utility model, the second concave block can be threadedly connected to the bidirectional threaded rod through the support rod, the first concave block and the threaded sleeve.

[0008] As a preferred embodiment of the automatically retractable tank track anti-vehicle mechanism of this utility model, the mounting base can form a threaded lifting connection with the support base through a second recess, a support rod, a first recess, a threaded sleeve, and a bidirectional threaded rod.

[0009] As a preferred embodiment of the automatically retractable tank track anti-vehicle mechanism of this utility model, the side wall of the mounting base is provided with five threaded grooves at equal intervals in the longitudinal direction, the side wall of the support base is threaded with bolts, and a sealing ring is adhered to the surface of the mounting base.

[0010] As a preferred embodiment of the automatically retractable tank track anti-vehicle mechanism of this utility model, the mounting base can be detachably and fixedly connected to the support base through threaded grooves and bolts.

[0011] As a preferred embodiment of the automatically retractable tank track anti-vehicle mechanism of this utility model, the mounting base can be sealed to the support base through a sealing ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By controlling the coordination between the motor, the second concave block, the support rod, the first concave block, the threaded sleeve, and the bidirectional threaded rod, the operator connects the power supply and starts the control motor. Subsequently, its output shaft rotates, driving the bidirectional threaded rod to rotate synchronously. Then, the threaded sleeve moves along the threads on the surface of the bidirectional threaded rod. Next, the threaded sleeve drives the first concave block to move, and the movement of the first concave block pushes the support rod upward. Then, the support rod pushes the second concave block upward, and the rise of the second concave block pushes the mounting base upward. This allows the height of the mounting base to be adjusted so that it retracts inside the support base. This allows the height of the mounting base to be automatically adjusted according to the installation space left at the bottom of the track, thus facilitating connection with the track and greatly improving installation efficiency.

[0013] By using the fit between the threaded groove, bolt, and sealing ring, the operator can rotate the bolt to connect with the threaded groove, thereby ensuring the stability of the mounting base after adjustment, which greatly improves the stability of use. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides the following technical solution: an automatically retractable tank-mounted rail anti-vehicle mechanism, including a mounting base 1, a hydraulic cylinder 2 mounted on the top of the mounting base 1, a connecting rod 3 mounted on the top of the mounting base 1, anti-vehicle blocks 4 rotatably connected to the surface of the connecting rod 3, a pull rod 5 rotatably connected to the bottom of the anti-vehicle blocks 4, the pull rod 5 being connected to the telescopic end of the hydraulic cylinder 2, the two anti-vehicle blocks 4 being able to rotate in opposite directions with the mounting base 1 through the pull rod 5 and the hydraulic cylinder 2, a tank-mounted rail 6 mounted on the top of the mounting base 1, a support base 7 connected to the bottom of the mounting base 1, a bidirectional threaded rod 8 rotatably connected to the inside of the support base 7 through a bearing, a threaded sleeve 9 threadedly connected to the surface of the bidirectional threaded rod 8, a first recess 10 connected to the top of the threaded sleeve 9, a support rod 11 rotatably connected to the inside of the first recess 10, a second recess 12 rotatably connected to the end of the support rod 11, the second recess 12 being connected to the bottom of the mounting base 1, and a control motor 16 mounted on the side wall of the support base 7.

[0018] In practical use, the car-stopping mechanism consists of a mounting base 1, a hydraulic cylinder 2, a connecting rod 3, a car-stopping block 4, and a pull rod 5. Its model is QZC9 car-stopper. In actual use, the car-stopper is installed at the bottom of the track 6 inside the mine cage. Then, the hydraulic cylinder 2 starts to work, driving the pull rod 5 to work. The pull rod 5 pulls the car-stopping block 4 to rotate in the opposite direction, thereby approaching the track 6 inside the cage. When the mine car is traveling on the track, the approaching car-stopping block 4 can fix the wheels of the mine car, thus preventing the mine car from slipping, moving, or overstepping its bounds, ensuring the safety and efficiency of transportation operations.

[0019] Preferably, the bottom end of the threaded sleeve 9 is in contact with the inner wall of the support base 7.

[0020] In actual use, the bottom end of the threaded sleeve 9 fits against the inner wall of the support base 7. When the operator controls the rotation of the bidirectional threaded rod 8, the threaded sleeve 9 will move along the threaded trajectory on the surface of the bidirectional threaded rod 8. At the same time, the threaded sleeve 9 is restricted by the inner wall of the support base 7 and will not rotate with the bidirectional threaded rod 8.

[0021] Preferably, the second concave block 12 can be threadedly connected with the bidirectional threaded rod 8 through the support rod 11, the first concave block 10 and the threaded sleeve 9.

[0022] In practical use, when the operator controls the rotation of the bidirectional threaded rod 8, its threaded sleeve 9 will move along the thread on the surface of the bidirectional threaded rod 8. Then, the threaded sleeve 9 will drive the first concave block 10 to move, and the movement of the first concave block 10 will push the support rod 11 to rise. Then, the support rod 11 will push the second concave block 12 to rise. Subsequently, the rise of the second concave block 12 will push the mounting base 1 to rise. In this way, the height of the mounting base 1 can be adjusted so that it can be retracted inside the support base 7. This allows the height of the mounting base 1 to be automatically retracted according to the installation space left at the bottom of the track, thus facilitating connection with the track.

[0023] Preferably, the mounting base 1 can form a threaded lifting connection with the support base 7 through the second recess 12, the support rod 11, the first recess 10, the threaded sleeve 9, and the bidirectional threaded rod 8.

[0024] In practical use, during the rotation of the bidirectional threaded rod 8, the threaded sleeve 9 moves along the thread on the surface of the bidirectional threaded rod 8, which in turn moves the first concave block 10. The movement of the first concave block 10 will cause the support rod 11 to rise. Subsequently, the support rod 11 will push the second concave block 12 to rise, and the second concave block 12 will in turn cause the mounting base 1 to rise. This linkage greatly improves the convenience of automatic retraction and extension of the height adjustment of the mounting base 1.

[0025] Preferably, the side wall of the mounting base 1 has five threaded grooves 13 that are equally spaced longitudinally, the side wall of the supporting base 7 is threaded with bolts 14, and the surface of the mounting base 1 is bonded with a sealing ring 15.

[0026] In practical use, the five threaded grooves 13 are provided so that when the mounting base 1 is raised or lowered, the bolts 14 can pass through the support base 7 and connect with the threaded grooves 13. This makes it convenient to connect the bolts 14 after adjusting the mounting base 1.

[0027] Preferably, the mounting base 1 can be detachably and fixedly connected to the support base 7 via the threaded groove 13 and bolt 14.

[0028] In practical use, after the operator screws the bolt 14 through the support base 7 into the threaded groove 13, it can fix the adjusted position of the mounting base 1. When connecting the bolt 14, a shim needs to be added to ensure the stability of the bolt 14 connection. At the same time, the connection of the bolt 14 can also bear the weight of the mounting base 1 and the hydraulic cylinder 2, connecting rod 3, vehicle stop block 4 and pull rod 5 connected to the mounting base 1.

[0029] Preferably, the mounting base 1 can form a sealed connection with the support base 7 through the sealing ring 15.

[0030] In practical use, the sealing ring 15 can seal the gap between the mounting base 1 and the support base 7, preventing dust from entering the gap between the support base 7 and the mounting base 1 when the mining vehicle is running under the track, thus avoiding difficulty in adjusting the height of the mounting base 1.

[0031] Working principle: First, the operator installs the car-stopping mechanism at the bottom of the track 6 inside the mine cage. Then, the bolt 14 is unscrewed to separate it from the threaded groove 13. After that, the power supply is connected to start the control motor 16. At this time, the output shaft controls the rotation of the bidirectional threaded rod 8. Its threaded sleeve 9 moves along the thread on the surface of the bidirectional threaded rod 8 and drives the first concave block 10 to move. Then, the movement of the first concave block 10 pushes the support rod 11 to rise, and then pushes the second concave block 12 to rise. Then, the rise of the second concave block 12 drives the mounting base 1 to rise. This allows the height of the mounting base 1 to be adjusted so that it can automatically retract and extend within the support. The mounting base 7 is internally supported, allowing the mounting base 1 to automatically adjust its retractable position according to the installation space left at the bottom of the track, facilitating connection with the track. After the track and mounting base 1 are connected, the bolts 14 are screwed in again to stabilize the position of the mounting base 1 after adjustment. When the mining vehicle travels on the track 6 inside the tank, the hydraulic cylinder 2 is activated and drives the pull rod 5 to operate. The pull rod 5 will pull the car-stopping block 4 to rotate in the opposite direction, bringing it closer to the track 6 inside the tank. In this way, when the mining vehicle travels on the track, the nearby car-stopping block 4 can fix the wheels of the mining vehicle, effectively preventing the mining vehicle from slipping, moving, or overstepping its bounds, ensuring the safety and efficiency of transportation operations.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
