Impact drainage type jack hydraulic oil replacing device

Abstract

The invention relates to the field of hydraulic oil, in particular to an impact drainage type jack hydraulic oil replacing device. The invention aims to provide an impact drainage type jack hydraulic oil replacing device. According to the technical scheme, the impact drainage type jack hydraulic oil replacing device comprises a bottom frame, a fixing assembly, an oil drainage assembly, an oil injection assembly and a control screen.The bottom frame is connected with the oil injection assembly. The oil drainage assembly is connected with the oil injection assembly. During use, a jack pressure relief hole valve is automatically unscrewed downwards, a small steel ball is located above the valve and moves downwards together with the valve, and meanwhile, the small steel ball is limited. When waste hydraulic oil flows out, the valve is automatically rotated upwards into an oil drainage hole, and meanwhile, the valve pushes the small steel ball into the oil drainage hole, so that the oil drainage hole is closed. Besides, new hydraulic oil is automatically and quickly injected into an oil inlet hole through impact, so that the efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of hydraulic oil, in particular to an impact drainage type jack hydraulic oil replacement device. Background technique [0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device on the liquid viscosity at the working temperature and the starting temperature. Since the viscosity change of the lubricating oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, the viscosity-temperature performance of the oil is also required. And shear stability should meet the various demands put forward by different uses. There are many kinds of hydraulic oils, and the classification methods are different. For a long time, ...

Problems solved by technology

[0005] In order to overcome the existing technology, one of the large-scale auto repair plants will use a large number of jacks, and the hydraulic oil of the jack needs to be replaced every six months to ensure its normal use. There is no special device for replacing the hydraulic oil of the jack. It is necessary to unscrew the valve located under the jack, then pour out the waste hydraulic oil, and then inject an appropriate amount of new hydraulic oil into the oil inlet hole on the upper part of the jack. The operation process is cumbersome and inefficient. At the same time, when pouring out the waste hydraulic oil , there will be a small steel ball falling out of the oil drain hole, and it is easy for workers to lose it during operation. At the same time, the outer surface of the small steel ball is stained with hydraulic oil, and it is difficult for workers to put it back into the oil drain hole of the jack. At the same time, when injecting new hydraulic oil , because the oil inlet hole of the jack is relatively small, the hydraulic oil will leak out when the worker operates, and the hydraulic oil is relatively viscous, resulting in slow oil filling speed and low efficiency. The purpose of this invention is to provide a hydraulic oil replacement device for impact drainage type
