[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] like Figure 1As shown, the present invention provides a transverse positioning mechanism, which is used to position the abrasive belt rail grinding vehicle, and the transverse positioning mechanism includes a support motion structure 10, a horizontal transverse push structure 20, and a vertical moving structure 30. Among them, the horizontal transverse push structure 20 is arranged on the support motion structure 10, and the support motion structure 10 is connected to the grinding vehicle chassis 100 by welding. The horizontal transverse push structure 20 is used to position the abrasive belt rail grinding vehicle in the first direction; the vertical moving structure 30 is arranged on the support motion structure 10, and the vertical moving structure 30 is spaced apart from the horizontal transverse push structure 20, and is used to position the abrasive belt rail grinding vehicle in the second direction; the horizontal transverse push structure 20 and the vertical moving structure 30 are used in combination to move the abrasive belt rail grinding vehicle to a preset grinding position to grind the rail 40.

[0059] In the above configuration, a horizontal push structure 20 is provided, and the horizontal push structure 20 is used to position the abrasive belt rail grinding vehicle in the horizontal direction. A vertical moving structure 30 is provided. The vertical moving structure 30 is used to position the abrasive belt rail grinding vehicle in the vertical direction, thereby improving the positioning and grinding accuracy of the abrasive belt rail grinding vehicle. This ensures that the abrasive belt rail grinding vehicle can grind the rail at the preset target grinding position, thereby avoiding the deviation between the actual grinding position and the target grinding position in the prior art and affecting the grinding quality. This improves the grinding quality and grinding efficiency of the abrasive belt rail grinding vehicle on the rail.

[0060] Specifically, Figure 4 As shown, in one embodiment, the support motion structure 10 includes a fixed support member 11, a support seat 12 and a first sliding assembly 13. The fixed support member 11 is arranged between two rails to be polished that are arranged at intervals along the third direction; the support seat 12 is slidably connected with the fixed support member 11 in the first direction; the first sliding assembly 13 is arranged on the support seat 12; and the horizontal transverse pushing structure 20 is connected with the first sliding assembly 13 and the support seat 12 at the same time, and is used to push the support seat 12 to slide on the fixed support member 11 along the first direction. Thus, the transverse pushing function of the horizontal transverse pushing structure 20 is realized.

[0061] It should be noted that the fixed support mechanism is connected to the grinding vehicle chassis 100 via the support rail 141 , and the fixed support member 11 is a part of the grinding vehicle chassis 100 , which is connected by welding.

[0062] Specifically, Figure 4 As shown, in one embodiment, the first sliding assembly 13 includes a transverse guide rail 131 and a transverse slider 132. The transverse guide rail 131 is extended along the first direction and arranged on the support seat 12; the transverse slider 132 is slidably arranged on the transverse guide rail 131 along the first direction, and the transverse slider 132 is connected to the horizontal transverse push structure 20.

[0063] In the above arrangement, the first sliding assembly 13 realizes the sliding connection between the horizontal push structure 20 and the support seat 12, thereby ensuring that the horizontal push structure 20 can subsequently push the support seat 12 to move laterally as a whole, thereby ensuring that the sanding belt rail grinding vehicle connected thereto can accurately move to the preset target grinding position.

[0064] Specifically, Figure 4 As shown, in one embodiment, the support motion structure 10 further includes a second sliding assembly 14, which includes a plurality of support rails 141 and a plurality of support sliders 142. The plurality of support rails 141 are arranged at intervals along the third direction; the plurality of support sliders 142 are arranged one by one on the plurality of support rails 141. This improves the stability and reliability of the second sliding assembly 14 during operation, thereby improving the stability and reliability of the sliding of the support seat 12.

[0065] Specifically, Figure 4 As shown, in one embodiment, the support motion structure 10 further includes a second sliding assembly 14, which includes four support rails 141 and four support sliders 142. The four support rails 141 are arranged at intervals along the third direction; the four support sliders 142 are arranged on the plurality of support rails 141 in a one-to-one correspondence.

[0066] Specifically, Figure 1 As shown, in one embodiment, four support rails 141 are distributed on both sides of the transverse central axis of the support base 12. Two of them are close to the edge of the support base 12, and the other two are close to the transverse central axis of the support base 12. This can further improve the stable supporting capacity of the support rails 141.

[0067] Of course, in alternative embodiments not shown in the drawings of the present application, the number of the support rails 141 can be set to one, three, five, or more than five. It should be noted that when the number of the support rails 141 is set to one, the single support rail 141 is set at the transverse center axis of the support seat 12.

[0068] Specifically, Figure 1 As shown, in one embodiment, the fixed support member 11 includes four channel steels, and the four channel steels are connected to the four support rails 141 in a one-to-one correspondence.

[0069] Specifically, Figure 2As shown, in one embodiment, the horizontal push structure 20 includes a push drive cylinder 21, a fixed base 22 and a limit assembly 23. The push drive cylinder 21 has a fixed end fixed on the support seat 12; the fixed base 22 is arranged on the lateral sliding block 132; the limit assembly 23 is arranged on the support seat 12; the drive end of the push drive cylinder 21 is used to push the fixed base 22 to slide, the fixed base 22 can drive the lateral sliding block 132 to slide along the first direction to a preset sliding position, and the limit assembly 23 and the drive end can limit the lateral sliding block 132 to the preset sliding position.

[0070] Specifically, Figure 2 As shown, in one embodiment, the horizontal push drive cylinder 21 adopts an electric push rod. Of course, a liquid cylinder and a gas cylinder can also be used according to actual conditions.

[0071] Specifically, Figure 2 As shown, in one embodiment, the limiting assembly 23 includes a spring support 231 and a limiting spring 232. The spring support 231 is arranged on the support seat 12 and is spaced apart from the fixed base 22 in the first direction; one end of the limiting spring 232 is connected to the spring support 231, and the other end of the limiting spring 232 is connected to the fixed base 22; when the traverse slider 132 slides to the preset sliding position, the limiting spring 232 presses the fixed base 22 against the driving end of the traverse drive cylinder 21.

[0072] In the above arrangement, the limit spring 232 has a buffering function, which can reduce the vibration of the support seat when it slides as a whole, thereby improving the smoothness of its sliding and avoiding the problem of poor smoothness when the support seat slides. This improves the stability and reliability of the lateral positioning mechanism when it works. Moreover, when the lateral sliding block 132 slides to the preset sliding position, the limit spring 232 is in a compressed state, which can reversely press the fixed base 22 against the driving end of the lateral push drive cylinder 21. In this way, the limit function of the limit assembly 23 is realized. Thereby, the positioning function of the lateral positioning mechanism in the first direction is realized.

[0073] Specifically, Figure 3 As shown, in one embodiment, the vertical moving structure 30 includes a vertical driving cylinder 31, a limiting assembly 32 and a guiding assembly 33. The vertical driving cylinder 31 has a fixed end fixed on the support seat 12; the limiting assembly 32 is connected to the driving end of the vertical driving cylinder 31; the guiding assembly 33 is fixed on the support seat 12 and connected to the limiting assembly 32, and the guiding assembly 33 is used to guide the limiting assembly 32 to slide along the second direction; the driving end of the vertical driving cylinder 31 can push the limiting assembly 32 to a preset moving position in the second direction.

[0074] It should be noted that, in theory, the telescopic direction of the vertical drive cylinder 31 can be set to the second direction, but the vertical drive cylinder 31 vibrates during the telescopic process, which will cause radial deviation during the telescopic process. In this embodiment, the guide assembly 33 is provided to reduce the radial deviation, thereby improving the positioning accuracy of the lateral positioning mechanism in the second direction.

[0075] Specifically, Figure 3 As shown, in one embodiment, the limiting assembly 32 includes a wheel shaft 321 and a limiting wheel 322. Among them, the wheel shaft 321 has one end connected to the driving end of the vertical driving cylinder 31; the limiting wheel 322 is rotatably arranged at the other end of the wheel shaft 321; when the limiting assembly 32 is located at the preset moving position, the limiting wheel 322 contacts the rail 40. In this way, the positioning function of the limiting assembly 32 is realized, thereby realizing the positioning function of the lateral positioning mechanism in the second direction.

[0076] Specifically, Figure 3 As shown, in one embodiment, the guide assembly 33 includes a guide rail bracket 331, a vertical guide rail 332, a vertical slider 333 and a slider bracket 334. The guide rail bracket 331 is fixed on the support seat 12; the vertical guide rail 332 is extended along the second direction and arranged on the guide rail bracket 331; the vertical slider 333 is slidably arranged on the vertical guide rail 332 along the second direction; the slider bracket 334 is fixed on the vertical slider 333, and the slider bracket 334 is connected to the slider bracket 334.

[0079] Specifically, the supporting motion structure of the lateral positioning device is fixed on the channel steel by the supporting guide rail 141 under the supporting slider 142. The vertical guide rail drives the limiting wheel 322 to move vertically; the horizontal push mechanism controls the lateral limiting force through the limiting spring 232, and ensures the lateral positioning of the abrasive belt rail grinding vehicle through the horizontal displacement of the push drive cylinder and the contact between the limiting wheel 322 and the rail 40.

[0080] Specifically, the horizontal push structure 20 of the lateral positioning device includes a push drive cylinder 21 (electric push rod), a fixed base 22, a limit spring 232, and a spring support 231. The limit spring 232 is fixedly connected to the push drive cylinder 21 and the spring support 231, the fixed base 22 is fixedly connected to the lateral sliding block 132, and the spring support 231 is fixedly connected to the support plate, so as to realize the horizontal movement of the lateral positioning mechanism.

[0081] Specifically, when moving horizontally, it is driven by the transverse push drive cylinder 21, which drives the fixed base 22 fixed on the transverse sliding slider 132 to compress the limit spring 232 along the direction of the transverse guide rail. The spring support 231 is driven by the pressure of the limit spring to drive the support plate and the support slider 142 to move along the support guide rail, so that the entire mechanism moves horizontally.

[0082] Specifically, the vertical moving structure of the lateral positioning device includes a vertical driving cylinder 31, a wheel shaft 321, a limiting wheel 322, a guide rail bracket 331, a vertical slider 333, a slider bracket 334, and a vertical guide rail 332. The support seat and the guide rail bracket 331 are fixed on the support plate; the vertical driving cylinder 31 is connected to the wheel shaft 321 through a pin, the slider bracket 334 and the limiting wheel 322 are connected to the wheel shaft 321, the guide rail bracket 331 is fixedly connected to the vertical guide rail 332, the vertical slider 333 is fixedly connected to the slider bracket 334, and the vertical slider 333 is matched on the vertical guide rail 332 to realize the vertical movement of the lateral positioning mechanism.

[0083] Specifically, when moving vertically, it is driven by the vertical driving cylinder, which drives the limiting wheel 322 and the slider bracket 334 matched therewith to move, and drives the vertical slider 333 fixed on the slider bracket 334 to move along the vertical guide rail 332, completing the vertical movement of the limiting wheel 322, so that the limiting wheel 322 contacts the rail 40, and completes the lateral positioning of the abrasive belt rail grinding vehicle.

[0084] Specifically, the supporting motion structure of the lateral positioning device includes a support seat 12, a lateral sliding block 132, a lateral guide rail 131, a channel steel, a support guide rail 141, and a support sliding block 142. The channel steel is fixedly connected to the support guide rail 141, the support sliding block 142 is fixedly connected to the support plate, the support sliding block 142 is matched on the support guide rail 141, the lateral guide rail 131 is fixedly connected to the support seat 12, the lateral sliding block 132 is fixedly connected to the fixed base 22, and the lateral sliding block 132 is matched on the lateral guide rail 131 to realize the support of the lateral positioning device.

[0085] The lateral positioning mechanism of the abrasive belt rail grinding vehicle of the present invention has the following beneficial effects:

[0086] 1. The horizontal push structure and the vertical motion structure are tightly connected with the supporting motion structure, which saves space and is easy to install and disassemble;

[0087] 2. The limit wheel is in an arc shape, which makes the contact with the rail smoother during the rail grinding process, thus avoiding the damage to the rail when the abrasive belt rail grinding vehicle moves;

[0088] 3. The horizontal push structure adopts a limit spring, which makes it easy for the lateral positioning mechanism to adjust the limit force between different tracks at any time to ensure the positioning effect.
