[0002] Railway transportation is a mode of land transportation in which locomotives pull train vehicles on two parallel rails. Railway stops are the terminals at the end of the rails. They are mostly made of mortared stone or welded with steel rails. They can absorb impact kinetic energy and are important safety equipment for protective stopping and buffering of train vehicles.

[0003] In the existing technology, fixed car stops are usually used, and the car stops are fixed to the track by bolts, so that the space occupied by the railway car stops does not decrease when not in use, so that the space occupied by the device is large, which is not conducive to the transportation and storage of the device, increases the difficulty of use for users, and affects the practicality of the device. At the same time, in order to maintain its stability, some railway car stops cannot be moved after being fixed and locked with a large number of bolts. When moving, all fixing bolts and weld joints need to be removed, and the position on the rail cannot be adjusted conveniently and quickly. Therefore, when moving the installation position of the car stop, it needs to be disassembled and reinstalled, which takes a lot of time and is difficult to operate, thereby increasing the workload and difficulty of the operator, affecting the operator's work efficiency. Utility Model Content

[0004] In view of the technical defects existing in the background technology, the present invention proposes a railway car stopper, which solves the above technical problems and meets the actual needs. The specific technical solution is as follows:

[0005] A railway car stopper comprises a buffer device and a device base carrying the buffer device, a connecting bracket is connected between the device base and the buffer device, and the device base is provided with a sliding locking structure;

[0006] The device base is composed of several basic bases, which include rail clamps, baffles, cover plates and clamping plates. The number of the rail clamps and the baffles are two, and they are arranged to form the sides of the basic base. The cover plate is set on the top of the basic base, and the clamping plate is clamped in the basic base formed by the enclosure.

[0007] The sliding locking structure consists of a sliding locking shaft and a transmission plate. The sliding locking shaft is slidably connected to the outer surface of the device base.

[0008] As an improvement to the above-mentioned solution, a slide groove is provided along the horizontal direction of the basic base, and the slide groove is arranged at an angle. The horizontal height of the slide groove close to one end of the buffer device is lower than the horizontal height away from the one end of the buffer device, and the two ends of the sliding locking shaft extend toward the outside of the basic base along the rail clamps on both sides.

[0009] As an improvement to the above solution, a single basic base includes at least two groups of clamping plates, which are respectively arranged at end positions close to the length direction of the basic base, and the opposite ends of the two groups of clamping plates are fixed to the transmission plates.

[0010] As an improvement to the above solution, a plurality of fixing holes are provided in the width direction of the basic base, the positions of the fixing holes correspond to the positions of the clamping plates, and a movable margin is reserved between the top of the clamping plate and the cover plate.

DETAILED DESCRIPTION

[0022] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0023] like Figure 1 and Figure 2As shown, a railway car stopper comprises a buffer device 1 and a device base supporting the buffer device 1, a connecting bracket is connected between the device base and the buffer device 1, and the device base is provided with a sliding locking structure 2;

[0024] like Figure 3 As shown, the base of the device is composed of several basic bases 3, which include rail clamps 31, baffles 32, cover plates 33 and clamping plates 34. The number of rail clamps 31 and baffles 32 is two, and they are arranged to form the side of the basic base 3. The cover plate 33 is set on the top of the basic base 3, and the clamping plate 34 is clamped in the basic base 3 formed by the enclosure.

[0025] The sliding locking structure 2 consists of a sliding locking shaft 21 and a transmission plate 22. The sliding locking shaft 21 is slidingly connected to the outer surface of the device base. The middle part of the transmission plate 22 is fixed to the sliding locking shaft 21, and the end of the transmission plate 22 is fixed to the clamping plate 34.

[0026] like Figures 3 to 5 As shown, in the technical solution of the basic base 3 of the present invention, the basic base 3 is formed by a rail clamp 31, a baffle 32 and a cover plate 33, wherein the rail clamp 31 is arranged at both ends of the rail, and the baffle 32 is arranged at both ends of the rail clamp 31 and fits with the surface of the rail, and the rail clamp 31 and the baffle 32 are arranged to form a rectangular cavity, and the clamping plate 34 is arranged at both ends of the cavity and is clamped and fixed by the rail clamp 31. During installation, after the clamping plate 34 is placed, the outer edge of the cover plate 33 is welded to the rail clamp 31 and the baffle 32 by welding.

[0027] It should be noted that the clamping plate 34 is arranged in the basic base 3 to increase the friction contact area between the basic base 3 and the surface of the rail. The sliding locking structure 2 is used to control the contact area between the basic base 3 and the rail. The sliding locking structure 2 moves the sliding locking shaft 21 along the length direction of the slide groove 35 to make the clamping plate 34 disengage from the contact with the rail, thereby reducing the contact area between the basic base 3 and the rail. After the clamping plate 34 is raised, the basic base 3 is only in contact with the rail through the baffle 32, the contact area is reduced, and the friction force is reduced during movement, which effectively reduces the workload of maintenance personnel.

[0028] like Figure 4 and Figure 5As shown, in the technical solution of the sliding locking structure 2 of the present invention, the sliding locking structure 2 is composed of a sliding locking shaft 21 and a transmission plate 22. The transmission plate 22 is fixed to the clamping plate. The sliding locking shaft 21 drives the transmission plate 22 to lift the clamping plate, thereby reducing the contact area between the base 3 and the rail.

[0029] Specifically, a slide groove 35 is provided along the horizontal direction of the basic base 3, that is, the end surface of the rail clamp 31 is provided with the slide groove 35, and the slide groove 35 is arranged at an angle. The horizontal height of the slide groove 35 close to the buffer device 1 is lower than the horizontal height of the end away from the buffer device 1. The two ends of the sliding locking shaft 21 extend toward the outside of the basic base 3 along the rail clamps 31 on both sides;

[0030] It should be noted that a movable margin is reserved between the top of the clamping plate 34 and the cover plate 33. This movable margin is used for the sliding locking structure 2 to separate the clamping plate 34 from the rail. After assembly and fixation, the sliding locking shaft 21 is at the lowest horizontal height position of the slide groove 35. When the railway gear is subjected to force, the base base 3 is subjected to the force transmitted from the direction of the buffer device 1. Under the action of the slide groove 35, the sliding locking shaft 21 converts the force transmitted horizontally from the buffer device 1 into a force pressing down the clamping block 41, so that it is kept compacted with the surface of the rail, thereby increasing friction.

[0031] It should be noted that if the horizontal height of the slide groove 35 close to the buffer device 1 is higher than the horizontal height away from the buffer device 1, then when the railway car stop is subjected to force, when the base base 3 is subjected to the force transmitted from the direction of the buffer device 1, the sliding locking shaft 21 cannot, under the action of the slide groove 35, convert the force horizontally transmitted from the direction of the buffer device 1 into a force to press down the clamping block 41. Instead, it will form a force to lift the clamping block 41 upward, and cannot achieve a buffering effect.

[0032] Furthermore, in the above scheme, a single basic base 3 includes at least two groups of clamping plates 34, and the clamping plates 34 are respectively arranged at the end positions close to the length direction of the basic base 3, and the opposite ends of the two groups of clamping plates 34 are fixed to the transmission plate 22.

[0033] Furthermore, in the above scheme, a plurality of fixing holes 36 are provided in the width direction of the basic base 3, and the positions of the fixing holes 36 correspond to the positions of the clamping plates 34. It should be noted that when the rail clamp 31 and the clamping plate 34 are fixed by inserting bolts in the fixing holes 36, the bottom end of the clamping plate 34 is in contact with the rail, and there is a movable gap between the top of the clamping plate 34 and the cover plate 33. During installation, the sliding locking shaft 21 can be moved to the lowest horizontal height position and the bolts can be inserted to fix it. Conversely, when it needs to be moved, it is only necessary to remove the bolts used for tightening to move the sliding locking shaft 21, thereby moving the railway car stop, without disassembling the entire basic base 3.

[0034] Furthermore, in the above scheme, the rail clamps 31 on both sides of the basic base 3 extend vertically downward, and the inner end faces of the rail clamps 31 on both sides are provided with a clamp-shaped clamping part 4, and the clamping part 4 is composed of a clamping block 41 and a clamping roller. The clamping blocks 41 are respectively arranged at both ends of the rail clamp 31, and the clamping rollers are arranged along the length direction of the rail clamp 31 and the ends are connected to the clamping blocks 41.

[0035] It should be noted that by moving the sliding locking shaft 21 in the slide groove 35, the clamping plate 34 is moved upward to fit the cover plate 33, thereby loosening the clamping on the top of the rail, so that the base of the device has a movable margin in the height direction, which is convenient for the movement of the entire device. The clamping rollers clamp both sides of the rail to reduce the friction force of the height lifting, which is convenient for maintenance personnel to lift the base of the device without affecting the friction force of the device base in the horizontal direction.

[0036] Furthermore, in the above solution, the basic base 3 includes a front basic base 5 and a rear basic base 6, the front basic base 5 and the rear basic base 6 are arranged in pairs, and the length of the rear basic base 6 is greater than the length of the front basic base 5;

[0037] like Figure 2 As shown, in the technical solution of the connecting bracket of the present utility model, the connecting bracket includes a transverse tie rod 1 7, a transverse tie rod 2 8, a longitudinal tie rod 9, an oblique support rod 10 and an oblique support rod 2 11;

[0038] Specifically, a transverse tie rod 7 is provided between the two front basic bases 5 arranged in pairs, and the transverse tie rod 7 is fixed to the front basic base 5 by bolts. A transverse tie rod 2 is provided between the two rear basic bases 6 arranged in pairs, and the transverse tie rod 2 8 is fixed to the rear basic base 6 by bolts. The lengths of the transverse tie rod 1 7 and the transverse tie rod 2 8 can be replaced with an adaptive size according to the width of the track. A longitudinal tie rod 9 is provided between the front basic base 5 and the rear basic base 6 by welding, and the longitudinal tie rod 9 connects the front basic base 5 and the rear basic base 6.

[0039] Furthermore, in the above scheme, an oblique support rod 10 is provided between the buffer device 1 and the front basic base 5, and an oblique support rod 2 11 is provided between the buffer device 1 and the rear basic base 6. The buffer device 1 transmits the impact force to the basic base 3 through the oblique support rod 10 and the oblique support rod 2 11.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
