Technical Field

[0001] The invention relates to the technical field of grinding wheels, and in particular to a high-efficiency orbital grinding wheel set and equipment thereof. Background Art

[0002] When the train runs on the track, there is a huge squeezing and punching force between the train wheels and the track. After long-term operation, the surface of the train track will have various damages and wear, such as wave wear, rail surface abrasion, rail surface peeling, rail side wear, cracks, rail head crushing and fat edges, which not only affect the comfort of the ride, but also cause safety hazards to driving safety. Therefore, the train track needs to be repaired regularly and irregularly using grinding equipment.

[0003] The upper end of the existing rails is mostly T-shaped, and the existing grinding equipment, such as a grinding car, makes the lower end surface of the grinding wheel contact with the upper surface of the rail and drives the grinding car on the surface of the rail so that the grinding wheel grinds the upper surface of the rail. However, during the actual use of the rail, due to differences in the use environment, the upper end side wall of the rail will also be worn and also need to be polished, so it is necessary to change the grinding state of the grinding wheel, and manual adjustment of the grinding wheel group is time-consuming and labor-intensive, which reduces the efficiency of rail grinding and is not convenient for use.

[0048] In order to carry out linkage in the switching mechanism 4, a fixing column 45 is fixedly connected to the center of the side wall of the mounting plate 41, and a transmission tube 46 is rotatably connected to the end of the fixing column 45. A gear groove 47 is opened on the side surface of the fixing column 45, and the opening of the gear groove 47 is aligned and adapted with the opening of the transmission tube 46. The length of the transmission tube 46 and the fixing column 45 after splicing is longer than the insertion rod 44, so as to prevent the insertion rod 44 from fixing the adjustment gear 42 on the surface of the transmission tube 46; the outer surface of the transmission tube 46 is fixedly connected with an external transmission tooth 461, and the inner surface of the transmission tube 46 is fixed It is connected with an internal transmission tooth 462, and multiple external transmission teeth 461 and internal transmission teeth 462 are distributed in a circular array on the surface of the transmission tube 46 with the axis of the transmission tube 46 as the array center. The surface of the external transmission tooth 461 is meshed with the surface of the adjusting gear 42, and both ends of the external transmission tooth 461 and both ends of the teeth on the surface of the adjusting gear 42 are inclined. By utilizing the fact that both ends of the external transmission tooth 461 and both ends of the teeth on the surface of the adjusting gear 42 are inclined, it is convenient to replace the adjusting gear 42 on the surface of the external transmission tooth 461 to avoid collision and obstruction of the end faces of the teeth.

The regulating cylinder 410 drives the transmission pipe 46 to slide on the surface of the gear column 49 through the connecting plate 411 and the fixing column 45, and then moves to the inside of different adjusting gears 42. Then, the adjusting motor 48 drives the gear column 49 to rotate, and then adjusts different mounting rings 32, avoiding manual operation, so as to facilitate the adjustment of the grinding wheel set.

[0051] Working principle:

The regulating cylinder 410 drives the connecting plate 411 to extend. The mounting plate 41 drives the inserting rod 44 to be pulled out from the inserting hole 43. At the same time, the fixing column 45 drives the transmission pipe 46 to slide on the surface of the gear column 49. When the transmission pipe 46 moves to the inside of the target mounting ring 32, the outer transmission gear 461 meshes with the adjusting gear 42 inside the target mounting ring 32. Start the adjusting motor 48. The adjusting motor 48 drives the inner transmission gear 462 to deflect through the gear column 49, and then the transmission pipe 46 drives the mounting ring 32 to deflect through the adjusting gear 42, so that the grinding wheel set on the surface of the target mounting ring 32 in contact with the track is changed.

[0054] Then stop the adjusting motor 48, reset the adjusting cylinder 410, reset the connecting plate 411 and drive the mounting plate 41, reinsert the insert rod 44 into the plurality of insert holes 43, start the mounting cylinder 36, so that the surface of the grinding wheel group contacts the surface of the track, and when the grinding vehicle is running, the track is grinded by the friction between the grinding wheel group and the track surface.

[0057] The raw materials for preparing the grinding wheel set are mixed and heated to 1490-1500 degrees Celsius, and stirred. After the raw materials are cooled, the heated raw materials are ball-milled into powder and then additives are added and stirred thoroughly.

[0058] The raw materials mixed with additives are placed in the grinding tool for high-temperature extrusion, and then the extruded ligand is sintered at a temperature of 1460-1480 degrees Celsius to obtain the finished grinding wheel.

[0059] By replacing the ore raw materials with copper-tin alloy powder, the self-sharpening and service life of the grinding wheel can be improved, and the problems encountered in grinding rails under extreme conditions of high frequency, high pressure and dry grinding can be solved. Grinding rails with it has the advantages of withstanding high pressure during grinding, long grinding mileage and no burning of the rails.
