[0006] Preferably, two insertion slots are opened on the surface of the mounting bracket, a rotating shaft is threadedly inserted into the insertion slots, and clamping pieces are fixedly connected to the ends of the rotating shafts, which can effectively ensure the center of gravity stability of the whole device and meet the long-term use of the device.

[0007] Preferably, the positions of the insertion slots are at the edges of the surface of the mounting bracket, and the insertion slots are distributed at relative angles on the surface of the mounting bracket, which more efficiently strengthens the matching coordination of each component during the operation of the overall device and effectively reduces the probability of various accidents that may occur during the use process.

[0009] Preferably, the clamping pieces are inserted on both sides of the surface of the spherical shaft at a relative angle, and the appearance of the clamping pieces is arc-shaped, which greatly strengthens the cooperation strength of the overall device during use and avoids the situation of asymmetric component matching during the use of the overall device.

[0010] Preferably, a bearing is fixedly connected to the end of each shelf board, and the end of each bidirectional lead screw corresponding to the shelf board is installed at the inner ring of the bearing. The overall device is supported according to the existing structure, the coordination performance of the overall device during use is strengthened, and the durability of the overall device during use is strengthened.

[0011] The beneficial effects of the present utility model are:

[0012] For the grinding device for railway maintenance, by placing the bottom wheels at both ends of the vehicle body on the surface of the railway track, the motor provides power for the grinding wheel and uses the counterweight to increase the mass of the entire grinding device. Then, the lead screw drives the mounting brackets on both sides to control the bottom wheels to fit the railway track, and the clamping pieces are controlled by the rotating shaft to keep the angle of the spherical shaft unchanged.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] As Figures 1-5 shown, in this embodiment: A grinding device for railway maintenance includes a vehicle body 1. Both sides of the lower surface of the vehicle body 1 are fixedly connected with mounting plates 5, and a rectangular sliding groove is opened on the lower surface of the mounting plate 5. The upper end of the mounting frame 8 slides inside the rectangular sliding groove, so as to facilitate the driving of the bidirectional lead screw 7. A jack 6 is opened on the outer surface of the mounting plate 5, and a bidirectional lead screw 7 is inserted into the jack 6. Two sections of thread grooves with opposite directions are opened on the surface of the bidirectional lead screw 7, and each of the two ends of the thread grooves occupies half of the length of the surface of the bidirectional lead screw 7. Threads on the two sections of thread grooves of the bidirectional lead screw 7 are sleeved with mounting frames 8 respectively. The bidirectional lead screw 7 provides power for the displacement of the two side mounting frames 8, so as to control the two side bottom wheels 10 to close or separate. With the two side bottom wheels 10 supporting on the ground on both sides of the railway track, and by using the rotation of the bidirectional lead screw 7 to control the displacement of the mounting frame 8 inside the rectangular sliding groove opened on the lower surface of the mounting plate 5, the bottom wheels 10 are driven to move away from or close to both sides of the railway track. A motor 2 and a counterweight 3 are respectively installed on the upper surface of the vehicle body 1, and they are distributed left and right. The output shaft of the motor 2 penetrates through the middle position of the surface of the vehicle body 1 and is connected with a grinding wheel 4. The motor 2 is used to drive the grinding wheel 4 to rotate, so as to grind and maintain the upper surface of the railway track. The counterweight 3 can increase the weight of the whole device and ensure that the lower grinding wheel 4 is in full contact with the surface of the railway track.

[0022] Furthermore, two slots 11 are opened on the surface of the mounting frame 8, and a rotating shaft 12 is threadedly inserted into the slots 11. The end of the rotating shaft 12 is fixedly connected with a clamping piece 13. The clamping piece 13 is controlled to be clamped by using the insertion shaft 12, so as to limit the rotation angle of the spherical shaft 9.

[0023] Furthermore, the slots 11 are located at the edge of the surface of the mounting frame 8, and are distributed at relative angles on the surface of the mounting frame 8. The relatively distributed slots 11 provide installation space for the clips 13, thereby more stably clamping and restricting the spherical shaft 9.

[0024] Furthermore, the lower surface of the mounting frame 8 is rotatably connected to a spherical shaft 9, and the lower surface of the spherical shaft 9 is fixedly connected to a bottom wheel 10, that is, there are two bottom wheels 10 on the left and right, and there are two groups of four bottom wheels 10 in the front and back. The bottom wheels 10 are used to slide on the lower end surface of the rail or on both sides of the rail, so that the staff can move the vehicle body 1 to perform mobile grinding of the rail.

[0025] Furthermore, the clips 13 are inserted at relative angles on both sides of the surface of the spherical shaft 9 , and the appearance of the clips 13 is arc-shaped. The clips 13 are used to limit the eccentric direction of the spherical shaft 9, thereby enhancing the direction limiting effect on the bottom wheel 10 .

[0026] Furthermore, each frame plate 5 is fixedly connected to a bearing at the end, and each end of the bidirectional screw rod 7 corresponding to the frame plate 5 is installed on the inner ring of the bearing. The bearing provides stability for the bidirectional screw rod 7, thereby facilitating the bidirectional screw rod 7 to control a corresponding set of mounting frames 8 and bottom wheels 10 to work.

[0027] The method of using this embodiment is: when using, please refer to Figures 1-5 First, the staff needs to manually set up the car body 1 on the surface of the rail, use the battery to provide power, and configure the corresponding motor control switch, then manually rotate the bidirectional screw rod 7 inside the jack 6, with the help of the bidirectional screw rod 7, the traction mounting frame 8 is displaced inside the rectangular slide groove opened on the lower surface of the frame plate 5, and the bottom wheel 10 located on the lower surface of the car body 1 is controlled to be distant or closed. Since the appearance of the rails is mostly I-shaped, but the specifications of different types of rails such as narrow gauge and meter gauge are inconsistent, the eccentric direction of the bottom wheel 10 is controlled by the spherical shaft 9, and the staff manually rotates the shaft 12 inside the slot 11 with the help of tools such as wrenches, and displaces it inside the mounting frame 8 with the help of the clip 13, so as to fix the angle of the spherical shaft 9, thereby avoiding the derailment of the car body 1 during the grinding and moving process.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
