Dumper chassis energy-saving lubricating system

Abstract

The invention provides a dumper chassis energy-saving lubricating system which comprises an oil storage tank, a grease filling oil cylinder, a grease distributor, a throttle and a oil-resistant pipe.The oil storage tank is connected with a cylinder body of the grease filling oil cylinder through an oil incoming pipeline, the cylinder body of the grease filling oil cylinder is connected with the grease distributor through an oil outgoing pipeline, the grease distributor is connected with the oil-resistant pipe through the throttle, a one-way valve is arranged on each of the oil incoming pipeline and the oil outgoing pipeline, and an electromagnetic air valve is connected on the oil incoming pipeline connecting the oil storage tank and the grease filling oil cylinder. The system can realizefilling of oil in different amounts at each point; a controller and a control switch are arranged in a driving cab, an operating worker can fill oil during working, an engineering vehicle does not need to stop working, and manual operation can be replaced; automatic filling can be realized each time when a dumper lifts and lowers according to needs, so that lifting energy of the dumper is utilized effectively, and energy-saving effect is realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle chassis lubrication, and in particular relates to an energy-saving lubrication system for a dump truck chassis. Background technique [0002] At present, due to the heavy production tasks of many mining vehicles, the turnover rate of the mining vehicles is high, and the failure rate of the chassis of the mining vehicles is relatively high. [0003] Dump truck is a kind of mine car, and its frequency of use is particularly high. There are many kinds of dump trucks, which can be divided into side dump dump trucks and rear dump dump trucks, and rear dump dump trucks. According to the position of the oil cylinder, it can be divided into a front-mounted dump truck and a mid-mounted dump truck, but no matter what kind of dump truck or structure, it has a lifting device and a chassis. During the unloading process of the dump truck, the pins and bearings of the chassis and the lifting device are mainly l...

AI Technical Summary

Problems solved by technology

There are many bearings and shaft pins in the lifting device and the chassis of the dump truck, and there are many refueling points. These refueling points are scattered separately, so it is difficult to fill each refueling point with quality and quantity every day. At present, the ones sold on the market Dump trucks are used for decentralized oil injection, that is, add oil nozzles at both ends of the shaft pin at each oil point, and use oil guns to fill oil nozzles one by one. However, due to uneven and discontinuous grease, it is difficult to ensure the injection volume and frequency. Requirements, so the reliability is not high; Existing, on various automobile chassis, grease (butter) is generally used to lubricate the connection pair of relative movement, and the grease nozzle is filled at a single point. In some small spaces, this operation is very difficult. difficulty

Especially for dump trucks, when working in a dusty environment, the grease is easy to dry, and the frequency of refueling increases

Sometimes the refueling is not timely due to various reasons, often causing early wear and tear of components

And it cannot be filled with oil while the vehicle is in use

The oil injection machines sold on the market generally inject oil into the oil pot first, and then supply oil. The oil supply speed is slow and the efficiency is low.
