Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, and in particular relates to a dust particle guide device generated by grinding. Background Art

[0002] After a period of use, steel rollers require regular grinding to ensure the rails remain functional. This is because during use, they are subjected to the intense forces of trains, which can cause surface wear, cracks, oxide layers, and rust. These problems not only disrupt the rail's optimal profile but also alter the wheel-rail contact, increase wheel-rail noise, accelerate the deterioration of vehicle and track components, shorten the rail's service life, and even threaten train safety. To eliminate these defects and restore the rails to their optimal profile, rail grinding technology is required. Grinding cuts the rail surface, removes defects, improves rail surface flatness, and enhances rail surface smoothness.

[0003] The existing grinding device cannot produce a large amount of waste materials, grinding wheel dust and steel waste when grinding rails during operation. The high-temperature particles accompanying grinding splash into the grinding area and easily adhere to the equipment and are difficult to remove. How to effectively absorb and process the large amount of dust and debris generated by grinding? Therefore, a dust particle diversion device generated by grinding is needed to assist in solving this problem. Utility Model Content

[0027] By setting up the clamping assembly 5, before work, the clamping column 51 can be placed on both sides of the rail and the screw rod 9 can be rotated. The threaded rod 8 and the screw rod 9 are threadedly matched, so that the threading rod 8 moves as a whole, and then drives the second clamping block 7 to move as a whole. During the movement of the second clamping block 7, the two clamping columns 51 are clamped on both sides of the rail, thereby completing the stable fixation of the grinding device and the rail, ensuring that the grinder 11 can be pushed to move along the rail for grinding processing during the grinding process.

[0028] Reference Figure 1 、 Figure 3 and Figure 4 As shown, a mounting frame 10 is installed at the bottom center of the connecting frame 1, and a grinder 11 is hingedly installed on the mounting frame 10. An adjusting rod 101 is rotatably embedded and installed at the top of the mounting frame 10. The adjusting rod 101 is passed through and installed on the connecting frame 1. The connecting frame 1 and the adjusting rod 101 are threadedly matched. A grinding disc 12 is rotatably set at the bottom of the grinder 11, and a grinding motor for driving the grinding disc 12 to rotate is installed on the grinder 11.

[0029] Through the cooperation between the adjustment rod 101 and the mounting frame 10, the position of the grinder 11 can be quickly adjusted according to work requirements during operation, ensuring that the grinder 11 can stably fit the rail.

[0030] The above-mentioned grinder 11 is equipped with a protective cover 13 at the outer edge of the grinding disc 12, and an air guide cavity 134 is symmetrically opened inside the protective cover 13. The air guide cavity 134 has an arc-shaped groove structure. A protruding rod 131 is installed at the front end of the grinder 11, and a conducting cavity 132 is opened inside the protruding rod 131.

During work, the high-temperature particles and exhaust gas accompanying the grinding can be effectively absorbed and filtered, and the high-temperature particles splashing into the grinding area and easily adhering to the equipment, requiring subsequent secondary cleaning, etc., can be avoided as much as possible, so as to ensure the smooth progress of subsequent work.

[0034] Working principle:

[0035] When it is necessary to grind the rails, etc., the receiving rollers 41 are overlapped and installed on the top of the rails, the clamping columns 51 are placed on both sides of the rails, and the screw rods 9 are rotated. The threaded rods 8 and the screw rods 9 are threadedly engaged, so that the threaded rods 8 are moved as a whole, and then the second clamping block 7 is moved as a whole. During the movement of the second clamping block 7, the two clamping columns 51 are clamped on both sides of the rails, thereby completing the stable fixation of the grinding device and the rails, and the adjusting rod 101 is rotated. The threaded rods 101 are engaged with the connecting frame 1 and the adjusting rod 101, so that the mounting frame 10 is lowered as a whole, and the grinding disc 12 is fitted to the top of the rails, and the mounting frame 10 is rotated.

[0036] During operation, the rotating motor and the grinding motor that drives the grinding disc 12 to rotate are started. The grinding motor drives the grinding disc 12 to rotate as a whole, thereby performing auxiliary grinding on the top surface of the rail. During the grinding process, the rotating motor drives the air guide wheel 19 to rotate as a whole. During the rotation of the air guide wheel 19, the air flow is driven, thereby driving the air flow inside the cleaning box 17, thereby driving the air flow at the duct 15 to be sucked in, and the guide cavity 132 at the protruding rod 131 and the air guide cavity 134 to be sucked in as a whole, thereby making the high-temperature particles and smoke generated by grinding be sucked in through the guide cavity 132 and the air guide cavity 134, and after being sucked in, enter the plug-in box 18, and the gas is assisted filtered by the filter 181, and the filtered gas is discharged through the air outlet 171. After filtering for a period of time, the plug-in box 18 needs to be pulled out to perform auxiliary cleaning on the inside of the receiving cavity 182.
