Description
Technical Field
The invention relates to the technical field of steel rail maintenance, in particular to a polishing device for polishing steel rails at a high speed based on a CBN grinding wheel.
Background
The steel rail is used as a crucial component in a railway transportation system and plays a key role in bearing the weight of a train and guiding the running direction of the train. The high-speed train is directly subjected to huge pressure and continuous friction force caused by high-speed running of the train. The rail has the defects of abrasion, cracks and the like in the long-term use process. Wear is the most common problem, and due to long-term friction with the wheels, the rail surface becomes thinner gradually, affecting its load carrying capacity. The occurrence of cracks can be caused by stress concentration, ageing of materials and the like, and if the cracks are not treated in time, the cracks can be continuously expanded, so that the running safety of a train is seriously threatened. In addition, the rail may be deformed, such as bent, twisted, etc., which may cause jolt during running of the train, reducing running stability. Therefore, polishing maintenance is required to be carried out regularly so as to ensure the safety and stability of train operation.
Currently, the devices for polishing the steel rail mainly comprise a traditional grinding wheel polishing device, a PGM-48 type steel rail polishing train, an RGH20C type turnout polishing train and the like. The conventional grinding wheel polishing device, the PGM-48 type steel rail polishing train and the RGH20C type turnout polishing train are mainly common corundum abrasive materials.

In addition, the common corundum abrasive can generate a large amount of dust in the process of polishing the steel rail, and besides the scrap iron generated by grinding the steel rail, the dust also contains a large amount of abrasive, adhesive materials and the like, so that the scrap iron is difficult to effectively recycle, peculiar smell can be generated to pollute the construction environment, and the generated dust and peculiar smell can influence the sight and working environment of operators and even cause harm to the health of the operators.

In operation, the second conveying motor 721 is utilized to drive the second conveying shaft 713 to rotate, the second conveying shaft 713 drives the second roller 714 to rotate, the second roller 714 rotates to drive the second conveying belt 715 to operate, the second magnetic plate 716 adsorbs the scrap iron on the ground onto the second conveying belt 715 when the second conveying belt 715 moves to one side facing the ground in the operation process, the second magnetic plate 717 isolates the adsorption of the scrap iron by the second magnetic plate 716 when the second conveying belt 715 moves to one side facing the carrier 100, meanwhile, the scrap iron is collected at a position close to the through hole 719 by the scraper 718, and at the moment, the scrap iron collected by the scraper 718 is sucked out by the dust collector 800 through the second dust suction hose 720, so that the effect and range of sucking the scrap iron are further increased.
In one embodiment of the present application, the first conveyor belt 707 and the second conveyor belt 715 are made of a flexible material that does not insulate magnetism, such as rubber, woven cloth, or the like. In the working process, when the first conveyor belt 707 and the second conveyor belt 715 are close to the first magnetic plate 708 or the second magnetic plate 716, scrap iron can be stably and reliably adsorbed, and when the first conveyor belt 707 and the second conveyor belt 715 are close to the first magnetic plate 709 and the second magnetic plate 717, the adsorption of the scrap iron can be timely isolated.
Referring to fig. 1 to 8, in a specific embodiment of the present application, a vacuum cleaner 800 includes a vacuum cleaner case 801, the vacuum cleaner case 801 is fixedly mounted on a carrier 100, a fan 802 is mounted on the vacuum cleaner case 801 towards an outer end of the carrier 100, a first dust suction hose 711 and a second dust suction hose 720 are fixedly and hermetically connected to an end of the vacuum cleaner case 801 far away from the fan 802, a plurality of partition plates 803 are fixedly connected to the inside of the vacuum cleaner case 801 at positions between the fan 802 and the first dust suction hose 711 and the second dust suction hose 720, a magnet 804 is fixedly mounted below the partition plates 803, and a detachable drawer 805 is slidably connected to an upper portion of the magnet 804 inside the vacuum cleaner case 801.
In the course of the operation, utilize fan 802 can blow out the inside air of dust collection box 801, the inside negative pressure that will form of dust collection box 801, the inside negative pressure of dust collection box 801 will be through first dust absorption hose 711 and second dust absorption hose 720 will receive the iron fillings that scrape box 710 and scraper blade 718 were collected and inhale the dust collection box 801 inside, will strike on division board 803 after the iron fillings got into the dust collection box 801 inside, division board 803 below fixed mounting's magnet 804 will adsorb the iron fillings inside drawer 805 simultaneously, on the one hand, adsorb the iron fillings in drawer 805 inside be convenient for centralized processing iron fillings, both retrieve or handle more high-efficient convenient. On the other hand, the adsorption of the scrap iron in the drawer 805 can keep the working environment clean and tidy, and prevent the scrap iron from scattering.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
