A Velcro hook surface 6 is bonded to one side surface of the strike plate 5, and a Velcro fur surface 7 is bonded to the Velcro hook surface 6. A protective pad 8 is bonded to the side surface of the Velcro fur surface 7 away from the Velcro hook surface 6. A support block 9 is fixed to one side surface of the bearing seat 1, and a movable plate 10 is movably connected to the support block 9. A second Spring 11, and the other end of the second spring 11 is fixed to the surface of the movable plate 10, a damper 12 is installed between the impact plate 5 and the bearing seat 1, the bottom surface of the bearing seat 1 is fixed with a bracket 15, and the surface of the bracket 15 is fixedly installed with an electric cylinder 16, the telescopic end of the electric cylinder 16 extends to the bracket 15 and a support plate 17 is installed, and the surface of the support plate 17 is detachably installed with a brake pad 18, a mounting hole 19 is provided on the surface of the brake pad 18, and a mounting bolt 20 is installed in the mounting hole 19, and one end of the mounting bolt 20 is threadedly connected to the threaded hole reserved on the surface of the support plate 17, and a battery 13 is installed inside the bearing seat 1.

[0026] When in use, first place the device on the rail. When the mine car needs to be intercepted, the small diesel engine drives the traction box 21 to the required position. Then the two electric cylinders 16 push the two support plates 17 closer to each other, so that the support plates 17 are locked with the rail to fix the device on the rail. When the mine car contacts the left side of the impact plate 5, it is intercepted to prevent it from moving. At this time, the impact plate 5 squeezes the damper 12, the first spring 3 and the second spring 11, and retracts at the same time to relieve the impact on the impact plate 5 and prevent the impact plate 5 from being deformed by the impact. When the mine car needs to be released, the two electric cylinders 16 push the two support plates 17 away from each other, so that the device can be released from the rail. , and then the traction box 21 drags this device to the rail ramp to release the mine car. By setting a detachable and replaceable brake pad 18, the clamping block is prevented from directly contacting and rubbing with the rail, thereby extending the service life of the clamping block. At the same time, the brake pad 18 can be removed for replacement and maintenance after loosening the mounting bolt 20, thereby ensuring the car-blocking effect. The operation is simple and convenient, and the difficulty of getting started is low. The detachable and replaceable protective pad 8 can reduce the noise generated by the collision during the car-blocking process, and avoids the direct contact and collision between the track-blocking car and the impact plate 5, thereby playing a certain protective effect. The Velcro bonding method is convenient and labor-saving to maintain, has strong practicality, and is worthy of promotion.

[0027] In this embodiment, the traction box 21 adopts a small diesel engine as a driving source, and the traction box 21 is fixedly connected to the supporting base 1 .

[0028] Specifically, the towing box 21 can be moved on the rail to avoid affecting and interfering with the trackless vehicle when it is idle.

[0029] In this implementation scheme: a control switch 14 is fixedly installed on the surface of the bearing seat 1, and the control switch 14 is electrically connected to the storage battery 13 and the electric cylinder 16 through wires.

[0030] Specifically, it is a common circuit connection structure, which is commonplace for those skilled in the art and will not be elaborated here.

[0031] In this implementation scheme: the depth of the mounting hole 19 is the same as the thickness of the brake pad 18.

[0032] Specifically, the brake pad 18 can be fixed on the support plate 17 through the mounting hole 19 and the mounting bolt 20, avoiding the direct contact and friction between the support plate 17 and the rail.

[0033] In this implementation scheme: the length of the mounting bolt 20 is less than the thickness of the brake pad 18.

[0034] Specifically, the mounting bolt 20 will not contact the rail, will not affect and interfere with the vehicle blocking effect, and ensure that the brake pad 18 can normally contact the rail.

[0035] In this implementation scheme: the surface area of the protective pad 8 is the same as the surface area of the impact plate 5.

[0036] Specifically, it plays a certain protective role and has the ability to reduce noise.

[0037] In this implementation scheme: the control switch 14 is an existing structure, and the control circuit can be realized by simple programming of those skilled in the art, which belongs to the common knowledge in this field. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0038] Working principle: When in use, first place this device on the railway track. When it is necessary to intercept the mine car, the small diesel engine drives the traction box 21 to tow it to the required position. Then, two electric cylinders 16 push two support plates 17 to approach each other, so that the support plates 17 are locked with the railway track to fix this device on the railway track. When the mine car contacts the left side of the impact plate 5, it is intercepted to prevent it from moving. At this time, the impact plate 5 squeezes the damper 12, the first spring 3 and the second spring 11, and at the same time retracts to relieve the impact received by the impact plate 5 and prevent the impact plate 5 from being deformed by the impact. When it is necessary to release the mine car, two electric cylinders 16 push two support plates 17 to move away from each other, so that this device can be released from the railway track. Then, the traction box 21 drags this device to move to the track ramp to release the mine car. By setting the detachable and replaceable brake pads 18, it is avoided that the clamping blocks directly contact and rub against the steel rail, which prolongs the service life of the clamping blocks. At the same time, after loosening the mounting bolts 20, the brake pads 18 can also be disassembled for replacement and maintenance to ensure the car blocking effect, and the operation is simple and convenient with a low starting difficulty. By the detachable and replaceable protective pad 8, it can reduce the noise generated by the collision during the car blocking process, and avoid the direct contact and collision between the rail car and the impact plate 5, playing a certain protective role, and the maintenance by the way of Velcro bonding is convenient, labor-saving and highly practical, which is worthy of promotion.

[0039] It should be noted that: The model specifications of the control switch 14, the electric cylinder 16 and the storage battery 13 need to be selected and determined according to the actual specifications of this device, etc. The specific selection calculation method adopts the existing technology in this field and can be obtained by purchasing in the market, so it will not be elaborated in detail.

[0040] The power supply and its principle of the control switch 14, the electric cylinder 16 and the storage battery 13 are clear to those skilled in the art, and will not be described in detail here.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
