Description

Technical Field

[0001] The utility model belongs to the technical field of rail maintenance in railway tracks, and in particular relates to a rail burr grinding device. Background Art

[0002] The single track of the track is composed of multiple steel rails connected end to end in sequence. There is a certain gap between the two connected steel rails, which plays a role in buffering, insulation, etc., and brings convenience to the later replacement. The ends of the two connected steel rails that are close to each other are burrs. The above-mentioned gap is formed between these two burrs. During long-term use, the gap between the two will gradually decrease, causing the two burrs to contact each other and cause relative friction, causing the burrs to deform. For the safety of driving, the burrs need to be polished and trimmed to restore them to their original state. The commonly used method is that the track maintenance personnel manually polish the burrs with a handheld grinder; this method has low polishing efficiency, and it is extremely difficult to meet the requirements for the regularity of the burrs after polishing. It is time-consuming and labor-intensive, and there are major safety hazards. Utility Model Content

Then, the fine-tuning mechanism 400 is adjusted so that the grinding mechanism 300 gradually grinds the flash. During the grinding process, the angle adjustment mechanism 500 is adjusted to change the angle of the grinding mechanism 300, thereby achieving all-round grinding of the flash end face, so that the gap between the two flashes reaches a predetermined range and the regularity of the flash is improved.

In summary, the present invention can effectively improve the grinding efficiency, reduce the difficulty of grinding, ensure that the regularity of the flash after grinding meets the requirements, save time and effort, and is safe to operate.

[0028] As a preferred embodiment of the present invention, Figure 2 、 7As shown, the assembly seat 100 includes a riser body 101, a connecting ear 102 is constructed at the lower end of the riser body 101, and the mounting shaft 200 is rotatably connected to the riser body 101. The positioning seat 600 of this embodiment includes a longitudinal plate 601, the upper end of which is detachably connected to the connecting ear 102. Two clamping plates 602 are symmetrically constructed on both sides of the longitudinal plate 601. The top of the rail contacts the lower end surface of the longitudinal plate 601, and the two clamping plates 602 are clamped on both sides of the rail. To prevent relative sliding between the positioning seat 600 and the rail, a friction layer is constructed on the end of the two clamping plates 602 that are close to each other and on the lower end surface of the longitudinal plate 601. This embodiment can also be equipped with magnets on the two clamping plates 602.

[0029] As a preferred embodiment of the present invention, Figure 2 As shown, the operating handle comprises a fixed sleeve and an operating rod. The fixed sleeve fits over the mounting shaft 200, and a locking bolt is threaded onto the fixed sleeve. The end of the locking bolt is fastened to the outer circumference of the mounting shaft 200. The operating rod in this embodiment is constructed on the fixed sleeve and extends radially outward from the fixed sleeve. During the grinding process, the operator simply holds the operating rod. To adjust the angle between the operating rod and the mounting shaft 200, the locking bolt is loosened, the fixed sleeve is rotated to a predetermined angle, and the locking bolt is tightened.

[0030] As a preferred embodiment of the present invention, Figure 5 、 6As shown, the angle adjustment mechanism 500 includes a mounting shell 501, an adjusting gear 502 and a clamping assembly. The mounting shell 501 is fixedly mounted on the mounting shaft 200, and the mounting shell 501 is connected and fixed to the assembly base 100. The adjusting gear 502 is fixedly assembled on the mounting shaft 200, and the axis of the adjusting gear 502 coincides with the axis of the mounting shaft 200. The clamping assembly of this embodiment is movably connected to the mounting shell 501, and the clamping assembly and the adjusting gear 502 are clamped together. The specific structure of the clamping assembly is that the clamping assembly includes an adjusting rod 504, a clamping tooth 508 and a connecting spring 507. One end of the adjusting rod 504 moves inwardly along the radial direction of the adjusting gear 502 through the end cover plate 503, and the end cover plate 503 is detachably connected to the mounting shell 501. The clamping tooth 508 is mounted on one end of the adjusting rod 504 inserted into the mounting shell 501, and the clamping tooth 508 is clamped between two gear teeth on the outer peripheral surface of the adjusting gear 502.

The working principle and advantages of this embodiment are as follows: when it is necessary to adjust the angle of the grinding mechanism 300, the pull ring 506 is pulled to drive the adjusting rod 504 to move back to the adjusting gear 502, so that the engaging tooth 508 disengages from the adjusting gear 502, and then the operating lever is pulled to drive the mounting shaft 200 to rotate a certain angle. At this time, the angles of the assembly seat 100 and the positioning seat 600 do not change, and the mounting shaft 200 drives the fine-tuning mechanism 400 and the grinding mechanism 300 to rotate synchronously by corresponding angles, thereby achieving the purpose of adjusting the angle of the grinding mechanism 300; after the adjustment is completed, the pull ring 506 is released, and under the action of the connecting spring 507, the adjusting rod 504 drives the engaging tooth 508 to return to its position and engage with the adjusting gear 502.

The longitudinal adjustment screw 403 extends along the length of the rail. The adapter 405 is fixedly connected to the mounting shaft 200, and the guide rail 401 is mounted on the adapter 405 and extends in the vertical direction. The sliding block 402 of this embodiment is slidably mounted on the guide rail 401.

A second operating handwheel 407 is mounted on the other end of the vertical adjustment screw 406, and the vertical adjustment screw 406 is threadedly connected to the adapter 405. The working principle and advantages of this embodiment are as follows: By rotating the first operating handwheel 404, the first operating handwheel 404 drives the sliding block 402 to move longitudinally along the rail via the longitudinal adjustment screw 403, thereby gradually grinding the flash end surface. By rotating the second operating handwheel 407, the second operating handwheel 407 drives the sliding block 402 to move axially along the vertical adjustment screw 406, thereby grinding the flash end surface at different depths, that is, adjusting the depth to which the grinding component of the grinding mechanism 300 extends into the gap between the two flashes.

[0032] As a preferred embodiment of the present invention, Figure 3 、 4As shown, the grinding mechanism 300 includes an assembly shell 301, a drive unit, and a grinding wheel 308.

Both the first transmission gear 304 and the second transmission gear 305 are installed in the assembly shell 301. In this embodiment, the drive motor 306 is mounted outside the assembly housing 301. The output shaft of the drive motor 306 is coaxially connected to the first rotating shaft 302. The grinding wheel 308 is mounted on the second rotating shaft 303, with the axis of the grinding wheel 308 coinciding with the axis of the second rotating shaft 303. The operating principle and advantages of this embodiment are as follows: By controlling the operation of the drive motor 306, it drives the second rotating shaft 303 to rotate through the transmission of the first transmission gear 304 and the second transmission gear 305. In turn, the second rotating shaft 303 drives the grinding wheel 308 to rotate and grind the flash.
