The special daily maintenance device for the jack provided by the invention can solve the problems that when an existing jack is in use, oil stains at the telescopic end of the jack needs to be manually cleaned and cannot be cleaned thoroughly due to manual cleaning, the jack can shake when the telescopic end of the jack is manually cleaned, and the like.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a special routine maintenance equipment for jacks. Background technique [0002] A hydraulic jack refers to a jack that uses a plunger or a hydraulic cylinder as a rigid jack. The hydraulic jack is composed of cylinders, pistons, cranks, oil valves and other components, such as Figure 7 As shown, the lower side of the telescopic end of an ordinary hydraulic jack is provided with a stud, and the lower end of the jack stud is provided with a slot; when the jack is in use, the outer surface of the telescopic end will be in contact with the hydraulic oil in the cylinder, so that the outer surface of the telescopic end of the jack is in contact with the hydraulic oil in the cylinder. Dust and impurities stick to the side. When the telescopic end of the jack shrinks, the dust and impurities stuck on the outer surface will be brought into the cylinder, resulting in problems such as short...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a special daily maintenance equipment for jacks, which can solve the problem that the oil stains on the telescopic ends of the jacks that exist when the existing jacks are in use need to be cleaned manually, and the oil stains on the telescopic ends of the jacks cannot be cleaned manually. When cleaning the telescopic end of the jack, the jack will shake and other problems. It can realize the function of cleaning the jack during daily use. It can automatically clean the oil stains on the telescopic end of the jack, clean the oil stains on the telescopic end of the jack thoroughly, and clean the jack. The jack will not shake when the telescopic end is cleaned.
