Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail maintenance, in particular to a polishing device for high-speed polishing of rails based on CBN grinding wheels. BACKGROUND

[0002] As a crucial component of railway transportation systems, rails play a key role in bearing the weight of trains and guiding their direction of travel. They directly withstand the tremendous pressure and continuous friction force brought about by high-speed train operation. Over time, rails may develop defects such as wear and tear and cracks. Wear and tear is the most common problem, as the rail surface gradually thins due to long-term friction with the wheels, affecting its load-bearing capacity. Cracks may occur due to stress concentration, material aging, or other reasons, and if not addressed promptly, they will continue to expand, posing a serious threat to train operation safety. In addition, rails may also deform, such as bending and twisting, which can cause the train to jolt during travel, reducing the smoothness of operation. Therefore, regular polishing maintenance is needed to ensure the safety and smoothness of train operation.

[0003] Currently, devices used for rail polishing mainly include traditional grinding wheel polishing devices, PGM-48 type rail polishing trains, and RGH20C type turnout polishing trains. Most of these devices use ordinary corundum abrasives.

[0004] When using ordinary corundum abrasives to polish rails, the grinding wheel cutting edge is consumed quickly and easily blunted, leading to a decrease in cutting ability, which requires more frequent replacement of abrasives, affecting the efficiency of rail polishing. Moreover, ordinary corundum abrasives generate a large amount of dust during the polishing process, which contains not only iron filings from the grinding process but also a large amount of abrasives and bonding materials. This not only makes it difficult to effectively recycle the iron filings but also causes environmental pollution due to the odor produced. The dust and odor generated can affect the operator's vision and working environment, and even pose a threat to the operator's health.

[0005] Therefore, how to improve the efficiency of rail polishing and effectively recycle dust is a problem that needs to be solved by those skilled in the art. SUMMARY

In the running process of the second transmission belt 715, when the second transmission belt 715 runs to the side facing the ground, the second magnetic plate 716 can adsorb the iron filings on the ground on the second transmission belt 715, when the second transmission belt 715 runs to the side facing the carrier 100, the second magnetic shielding plate 717 can isolate the adsorption of the second magnetic plate 716 on the iron filings, at the same time, the scraper 718 can collect the iron filings close to the through hole 719, at this time, the dust collector 800 can suck out the iron filings collected by the scraper 718 through the second dust collection hose 720, so as to further increase the effect and range of the iron filings suction.

[0062] In an embodiment of the present application, the first transmission belt 707 and the second transmission belt 715 are made of flexible material which does not isolate magnetism, such as rubber, woven cloth, etc. In the working process, the first transmission belt 707 and the second transmission belt 715 can stably and reliably adsorb the iron filings when they are close to the first magnetic plate 708 or the second magnetic plate 716, and can timely isolate the adsorption of the iron filings when they are close to the first magnetic shielding plate 709 and the second magnetic shielding plate 717.

[0063] Please refer to Figures 1-8In an embodiment of the present application, the dust collector 800 comprises a dust collection box 801 fixedly installed on the carrier 100, a fan 802 fixedly installed on the dust collection box 801 towards the outer end of the carrier 100, and a first dust collection hose 711 and a second dust collection hose 720 fixedly and sealingly connected to one end of the dust collection box 801 away from the fan 802. A plurality of partition plates 803 are fixedly connected to the inside of the dust collection box 801 between the fan 802 and the first dust collection hose 711 and the second dust collection hose 720. A magnet 804 is fixedly installed on the inside of the dust collection box 801 below the partition plates 803. A detachable drawer 805 is slidingly connected to the inside of the dust collection box 801 above the magnet 804.

[0064] In the working process, the fan 802 can blow out the air inside the dust collection box 801, so that a negative pressure is formed inside the dust collection box 801. The negative pressure inside the dust collection box 801 can suck the iron filings collected by the collection box 710 and the scraper 718 into the inside of the dust collection box 801 through the first dust collection hose 711 and the second dust collection hose 720. After the iron filings enter the inside of the dust collection box 801, they will impact on the partition plates 803, and the magnet 804 fixedly installed below the partition plates 803 will attract the iron filings into the inside of the drawer 805. On the one hand, attracting the iron filings into the inside of the drawer 805 can facilitate the centralized treatment of the iron filings, and is more efficient and convenient for recycling or disposal. On the other hand, attracting the iron filings into the inside of the drawer 805 can keep the working environment clean and avoid the scattering of the iron filings.

[0065] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
