Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for grinding vehicles, in particular to a dust scraping device for the guide columns of a rail grinding vehicle. Background Technique

[0002] A dust scraping device for the guide columns of a rail grinding vehicle simplifies the replacement steps and improves the operation efficiency through the intelligent design of a new type of scraping ring and the dust scraping device. Operators do not need professional techniques and experience, and can complete the quick and safe replacement of the scraping ring by using a disposable replacement device. At the same time, safety factors are considered, the operation risk is reduced, and the safety of operators is improved. The disposable replacement method of this device reduces the probability of accidents and greatly reduces the maintenance workload, improving the work efficiency. An existing screw drive type rail grinding device for rail transit (publication number: CN108277707A) has the following drawbacks and needs further improvement.

[0003] 1. Traditional equipment requires complex disassembly and installation steps, such as disassembling multiple components and using tools for operation. This will increase the replacement time and lead to low operation efficiency. Replacing the scraping ring of traditional equipment requires skilled techniques and experience, and operators need to have professional knowledge and skills. For those who are not familiar with the operation, the process of replacing the scraping ring is relatively difficult, and errors or improper operations are likely to occur. Replacing the scraping ring of traditional equipment involves the disassembly and installation of mechanical equipment, and there are certain operation risks. If the operation is improper or does not conform to safety specifications, accidents may be triggered, threatening the safety of operators. Therefore, there is an urgent need for a dust scraping device with a new type of scraping ring.

[0004] 2. Traditional equipment requires cumbersome disassembly and installation steps, such as removing each guide column one by one and taking off and installing new scraping rings one by one. This will increase the replacement time and lead to low maintenance work efficiency. Replacing the scraping ring of traditional equipment requires skilled techniques and experience, and operators need to have professional knowledge and skills. For those who are not familiar with the operation, the process of replacing the scraping ring is relatively difficult, and errors or improper operations are likely to occur. Replacing the scraping ring of traditional equipment involves the disassembly and installation of mechanical equipment, and there are certain operation risks. If the operation is improper or does not conform to safety specifications, accidents may be triggered, threatening the safety of operators. There are a large number of scraping rings on the rail grinding vehicle that need to be replaced, and at least more than half of the scraping rings need to be replaced every year. Traditional equipment needs to replace the scraping rings one by one, with a large maintenance workload and time-consuming and laborious.
