Description

Technical Field

[0001] This utility model relates to the field of processing equipment, and in particular to a device for grinding the thick edges of steel rails. Background Technology

[0002] Railway rails have numerous joints, each with an insulating clamp that insulates adjacent rails, forming a circuit. This is a crucial element ensuring safe railway operation. Because railways operate in one direction for extended periods, rail joints are deformed by wheel pressure, forming protruding thick edges. Larger thick edges can pose a short-circuit hazard to adjacent rails. Therefore, it is essential to periodically remove these thick edges from rail joints.

[0003] Currently, grinding is done manually using ordinary angle grinders with cutting discs. Because positioning is impossible, the angle and depth of grinding can only be controlled manually, resulting in inconsistency after grinding. This also damages the insulating plates and reduces the efficiency of rail maintenance. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-5 As shown, this utility model proposes a rail edge grinding device, including a fixed base 100, a fixing member 200, and a grinding mechanism 300. The fixed base 100 is provided with a guide groove 101. The fixing member 200 is connected to the fixed base 100 and fixes the fixed base 100 to the rail. The grinding mechanism 300 is connected to the guide groove 101 and moves along the length direction of the guide groove 101 to grind the edge. The grinding mechanism 300 includes a grinding disc 301. The edge of the grinding disc 301 is designed with an incline to grind the edge to the corresponding angle.

[0029] It should be noted that the rail edge grinding device consists of two parts: a grinding mechanism 300 for grinding the rail edge and a mechanism to assist the grinding mechanism 300 in determining the position of the rail to be ground. The fixed seat 100 is fixed to the rail by a fixing member 200. During the fixing process, it is ensured that the guide direction of the guide groove 101 on the fixed seat 100 is consistent with the direction of the edge to be ground, so that the grinding mechanism 300 will not deviate from its grinding position. The grinding disc 301 has a disc structure, and its edge is set with a certain inclination angle according to the required grinding angle of the rail edge, such as 20°, 25°, 30°, etc. Similarly, the inclination angle is adjusted according to the rail edge... To adjust the required grinding depth, a grinding disc 301 with a corresponding diameter can be selected. It is important to emphasize that when the grinding mechanism 300 is connected to the guide groove 101, its position on the fixed base 100 is fixed, meaning the grinding direction of the thick edge is fixed, ensuring consistency in the grinding. Similarly, due to the fixed position, when the grinding depth or angle of the thick edge needs to be adjusted, the overall size of the grinding disc 301 or its edge inclination can be changed. This allows for quick positioning of the grinding position on the rail, while ensuring consistency in the grinding angle and depth in the same grinding direction, reducing the risk of damaging the insulating clamp and improving the efficiency and accuracy of the grinding work.

[0030] It should be noted that the grinding mechanism 300 includes a power source (not shown in the attached figure) that drives the grinding disc 301 to rotate at high speed. This power source can be an angle grinder after the disc is removed, or a drive motor with a rotating shaft.

[0031] In one embodiment of this application, a positioning block 102 is provided on one side of the fixed base 100. The positioning block 102 is used to position the fat edge to assist the grinding operation of the grinding disc 301.

[0032] It should be noted that, in order to further determine the grinding position, a positioning block 102 is added to one side of the fixed seat 100. It should be emphasized that the position of the positioning block 102 is located next to the guide groove 101, which can be understood as the grinding area. When the fixed seat 100 is fixed to the rail, the grinding area of ​​the grinding mechanism 300 can be directly determined by visually determining the position of the positioning block 102 on the rail, thus realizing rapid positioning of the grinding area.

[0033] In one embodiment of this application, a limiting plate 103 is provided on the fixed seat 100. The limiting plate 103 is used to abut against the side of the rail to limit the offset of the fixed seat 100 on the rail.

[0034] It should be noted that, in order to further ensure that the fixing seat 100 does not shift when fixed to the rail, and to ensure that the grinding direction of the thick edge is always consistent, a limiting plate 103 structure is added to the fixing seat 100. The limiting plate 103 is placed on the side of the fixing seat 100, forming an adjacent surface with the fixing seat 100 at a certain angle. The fixing seat 100 is attached to the top surface of the rail, and the limiting plate 103 is attached to the side surface of the rail. The angle between the top surface and the side surface of the rail matches the angle of the adjacent surface formed by the limiting plate 103 and the fixing seat 100. Therefore, the angular deviation of the fixing seat 100 on the rail is limited by the limiting plate 103, thereby ensuring that the grinding direction of the grinding mechanism 300 is always consistent when grinding the thick edge.

[0035] In one embodiment of this application, two limiting plates 103 are provided and are respectively placed on both sides of the fixing seat 100. The two limiting plates 103 are used to clamp the rail therein to limit the offset of the fixing seat 100 on the rail.

[0036] It should be noted that, since the above embodiment uses a single limiting plate 103 to limit the offset of the fixing seat 100, although it can have a certain limiting effect, in actual operation, it is necessary to keep applying an external force to the limiting plate 103 to keep it close to the side of the rail to prevent the limiting plate 103 from detaching from the side of the rail, thereby affecting the offset of the fixing seat 100 on the top surface of the rail. In this embodiment, by using a structure of two limiting plates 103, it should be explained that the distance between the two limiting plates 103 is exactly or slightly larger than the width of the rail, so that the two limiting plates 103 can clamp the rail in it. Therefore, the two limiting plates 103 restrict each other, so the limiting plate 103 will not detach from the side of the rail.

[0037] In one embodiment of this application, the grinding mechanism 300 further includes a traction member 302, which is connected to the guide groove 101 and moves along the length of the guide groove 101, wherein the grinding disc 301 is rotatably connected to the traction member 302.

[0038] It should be noted that, in order to ensure the smooth movement of the grinding mechanism 300 on the guide groove 101, the traction member 302 serves as a support for the grinding disc 301 and as a medium for the movement of the grinding disc 301 on the guide groove 101. The traction member 302 can be a slider, a slide plate with rollers, a roller, or other structures.

[0039] In one embodiment of this application, the traction member 302 includes a roller, the tread of which contacts the bottom surface of the guide groove 101 and rolls along the length of the guide groove 101, wherein the grinding disc 301 is rotatably connected to the central shaft of the roller.

[0040] It should be noted that, as mentioned above, the traction component 302 is preferably a roller structure. This roller is an insulated roller, and the contact area between the roller tread and the bottom surface of the guide groove 101 is small, so as to improve the smoothness of the roller in the guide groove 101, facilitate the worker's grinding operation, and improve grinding efficiency. In this embodiment, the power source is directly connected to the grinding disc 301. A high-speed bearing structure is connected between the roller and the grinding disc 301, and it is pressed and locked by a pressure plate. The roller is connected to the grinding disc through the high-speed bearing to realize the relative movement between the grinding disc and the insulated roller, while buffering the inertia generated by the high-speed rotation of the grinding disc and reducing the wear of the insulated roller.

[0041] In one embodiment of this application, the fastener 200 includes a magnetic element that can be magnetically attached to a rail.

[0042] The mounting base 100 is provided with at least one mounting groove 104, and multiple magnetic components are provided. The number of magnetic components corresponds to the number of mounting grooves 104, and each magnetic component is installed in its corresponding mounting groove 104.

[0043] It should be noted that the magnetic component adopts a magnet structure, which can be magnetically attracted to the rail, thus facilitating the fixing of the fixing seat 100 to the rail. This allows workers to quickly adjust the fixing of the fixing seat 100 to any position on the rail. In order to improve the stability of the fixing of the fixing seat 100 on the rail, multiple magnetic components are added in this embodiment, and correspondingly, the same number of fixing slots 104 are opened for each magnetic component.

[0044] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
