Specific Embodiments

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0029] As Figure 1 and Figure 2 shown, the anti-rolling and braking device for railway vehicles includes: a base frame 30, the base frame 30 is in the shape of a rectangular rod, the top ends of both ends of the base frame 30 are respectively fixedly connected with rectangular rods, and the two ends of the rectangular rods are respectively symmetrically and fixedly connected with the same base frame 30;

[0030] Cover plate 20, the cover plate 20 is a rectangular plate, the cover plate 20 is symmetrically and movably connected between the symmetric base frames 30, a anti-slip block 22 is fixedly connected to the rear wall surface of the cover plate 20, the anti-slip block 22 is a right-angled triangular block, and the inclined surface of the anti-slip block 22 is an arc surface. This is the existing technology, so it will not be elaborated here.

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in

[0033] shown, the clamping rod 21 is a U-shaped rod with an opening facing downwards, the rotating clamping plate 23 is a rectangular plate, the rotating clamping plate 23 can be turned downwards between the symmetric clamping rods 21, the abutting plate 26 is a horizontally placed L-shaped rod, the rotating column 32 is a circular rod, and symmetrical threads are respectively provided on the arc surfaces at both ends of the rotating column 32. The locking structure further includes a rotating shaft 24, a sliding groove 25, a sliding block 27, a screw cylinder 28 and a hexagonal cylinder 33. The rotating shaft 24 is symmetrically and fixedly connected to the front and rear wall surfaces of each rotating clamping plate 23. The sliding groove 25 is opened on the side walls of each group of clamping rods 21 facing each other. The sliding block 27 is symmetrically and fixedly connected to both sides of each abutting plate 26 respectively. The screw cylinder 28 is fixedly connected to the wall surfaces of the symmetric abutting plates 26 facing each other. The hexagonal cylinder 33 is fixedly connected to the middle wall surface of the rotating column 32. The rotating shaft 24 is a cylindrical shape. The rotating clamping plate 23 is rotationally connected between the symmetric clamping rods 21 through the rotating shaft 24. The sliding groove 25 is a rectangular groove. The abutting plate 26 is slidably connected in the sliding groove 25 on the wall surface of the clamping rod 21 through the symmetric sliding blocks 27. The screw cylinder 28 is a circular tube, and a thread adapted to the thread on the wall surface of the rotating column 32 is provided in the cavity of the screw cylinder 28. The screw cylinder 28 can adapt to the diameter of the rotating column 32. The hexagonal cylinder 33 is a hexagonal column;

[0033] When in use, first, the rotating card plate 23 is in a vertical state, and then the card rod 21 is inserted into the rail, and then the hexagonal cylinder 33 is rotated by a wrench. When the hexagonal cylinder 33 rotates, the rotating column 32 is driven to rotate synchronously, and the rotating rotating column 32 drives the symmetrical screw cylinder 28 to move synchronously in opposite directions due to the symmetrical threads opened on the wall surfaces at both ends. The symmetrical screw cylinder 28 can drive the corresponding contact plate 26 on each side to translate at the bottom of the cover plate 20 when moving, and the slider 27 can move along the slide groove 25 with the movement of the contact plate 26. The contact plate 26 can move along the rail when moving. The top part moves and the upper part of the rotating card plate 23 contacts the corresponding direction, so that the rotating card plate 23 is tilted, and the rotation of the rotating column 32 is stopped when the tilted rotating card plate 23 just contacts the inclined surface of the rail, and the lower part of the contact plate 26 also contacts the other side of the rail opposite to the rotating card plate 23. At this point, the installation is completed. When it is necessary to disassemble, the hexagonal cylinder 33 is rotated in the opposite direction so that the rotating column 32 rotates and drives the contact plate 26 to no longer contact the rotating card plate 23, so that the position of the rotating card plate 23 is unlocked, and then the rotating card plate 23 is moved to a vertical state, and the entire device can be directly removed from the rail;

[0034] To summarize, by setting up a locking structure, it can be quickly installed on the rail for use. The locking structure can drive the symmetrical resistance plate 26 and the turn plate 23 to lock the device on the rail through the thread on its wall by simply rotating the rotating column 32 to prevent the vehicle from slipping. Therefore, compared with the prior art, this solution only needs to rotate the rotating column 32 during installation to achieve the best anti-slip effect.

[0035] like Figure 1 and Figure 5 As shown, the wall surface of the base frame 30 is provided with an adjustment structure, which includes a connecting rod 31, a limiting groove 34, a limiting plate 35, a locking groove 36 and a locking rod 37. The connecting rod 31 is symmetrically fixedly connected between the symmetrical base frames 30. The limiting groove 34 is provided at the top and bottom of both sides of each base frame 30. The limiting plate 35 is symmetrically fixedly connected up and down on both sides of each cover plate 20. The locking groove 36 is symmetrically provided on both sides of each base frame 30. The locking rod 37 is threadedly connected in the locking groove 36. The connecting rod 31 is composed of a horizontal rectangular rod and a vertical rectangular rod. The rotating column 32 can rotate between the vertical rectangular rods between the symmetrical connecting rods 31. The symmetrical limiting plates 35 on both sides of the cover plate 20 can slide in the corresponding limiting groove 34 on each side. The side wall surface of the cover plate 20 is provided with the same locking groove 36. The locking rod 37 can pass through the locking groove 36 on the base frame 30 and the wall surface of the cover plate 20. A plurality of locking grooves 36 on the wall surface of the base frame 30 are provided in a linear array.

[0036] In actual use, when the symmetrical cover plate 20 needs to be adapted to the rails of different intervals, the locking rod 37 is first screwed out from the corresponding locking groove 36, and then the symmetrical cover plate 20 is slid along the symmetrical base frame 30. At this time, each limit plate 35 can slide along each corresponding limit groove 34. After the adjustment is completed, the locking rod 37 is screwed into the corresponding locking groove 36 of the base frame 30 and the wall surface of the cover plate 20 at the same time to lock the position of the cover plate 20;

[0037] In summary, by setting the adjustment structure, the spacing between the symmetrical cover plates 20 can be flexibly controlled so as to adapt to different tracks. The adjustment structure can effectively improve the application scope of the device.

[0038] Working principle: first, put the rotating card plate 23 in a vertical state, then insert the card rod 21 on the rail, and then use a wrench to rotate the hexagonal cylinder 33. When the hexagonal cylinder 33 rotates, it will drive the rotating column 32 to rotate synchronously. The rotating rotating column 32 drives the symmetrical screw cylinder 28 to move synchronously in opposite directions due to the symmetrical threads opened on the wall surfaces at both ends. The symmetrical screw cylinder 28 can drive the corresponding contact plate 26 on each side to move horizontally at the bottom of the cover plate 20 when moving. The slider 27 can move along the slide groove 25 with the movement of the contact plate 26. The contact plate 26 can move along the top of the rail when moving. The rotating column 32 is moved and the upper part of the rotating card plate 23 is abutted in the corresponding direction, so that the rotating card plate 23 is tilted, and the rotation of the rotating column 32 is stopped when the tilted rotating card plate 23 is flush with the inclined surface of the rail. At this time, the lower part of the abutment plate 26 will also abut on the other side of the rail opposite to the rotating card plate 23. At this point, the installation is completed. When disassembly is required, the hexagonal tube 33 is rotated in the opposite direction to rotate the rotating column 32 to drive the abutment plate 26 to no longer abut the rotating card plate 23, so that the position of the rotating card plate 23 is unlocked, and then the rotating card plate 23 is moved to a vertical state, and the entire device can be directly removed from the rail.
