Intelligent automatic lubricating system for chain

Abstract

The invention discloses an intelligent automatic lubricating system for a chain, and belongs to the field of dump trucks. The intelligent automatic lubricating system for the chain comprises a mist-spray type nozzle formed in a chain wheel on a transmission shaft, the mist-spray type nozzle is formed in a lubricant spray pipe, the lubricant spray pipe communicates with a lubricant storage tank, and an electromagnetic valve I is installed on the lubricant spray pipe; and the lubricant storage tank communicates with an air supply device through an air delivery pipe, an electromagnetic valve II is installed on the air delivery pipe, and the electromagnetic valve I and the electromagnetic valve II are both controlled by an electric cabinet. According to the invention, the electromagnetic valve I and the electromagnetic valve II are both controlled by the electric cabinet, air pressure is properly regulated and controlled through an air source provided by the air supply device and real-time display of an air pressure flowmeter, the air source enters the lubricant storage tank, and the air source and a lubricant are sprayed to the mist-spray type nozzle through the lubricant spray pipe to form mist spray so as to lubricate the chain wheel and the chain.

Description

technical field [0001] The invention relates to the field of dump trucks, in particular to an intelligent automatic lubrication system for chains. Background technique [0002] The unloading mechanism is an important part of the self-unloading semi-trailer. Compared with the traditional hydraulic cylinder unloading method, the chain unloading mechanism can realize unloading without lifting the entire carriage, which has the advantages of safety, reliability and high unloading efficiency. The chain-type unloading mechanism is set on the frame at the bottom of the carriage, and relies on the chain and the conveyor belt on it to seal the bottom of the carriage and unload the materials in the carriage in translation. [0003] The chain is the core component of the entire chain unloading mechanism. The chain not only bears the weight of all the materials in the compartment, but also drags the materials to move and unload. The weight of the semi-trailer generally ranges from sever...

AI Technical Summary

Problems solved by technology

However, the existing technology lacks effective means for the daily lubrication and maintenance of the chain. The existing chain lubrication means mainly lubricate the chain through an oil outlet pipe. When lubricating, the staff opens the valve, and then the lubricating oil is sprayed on the chain through the oil outlet pipe. There are several disadvantages in the lubrication method. First, the chain lubrication time depends on manual operation, and manual operation inevitably has the problem of forgetting to lubricate or not lubricating on schedule, which leads to the chain not being lubricated and maintained in time, and eventually leads to an increase in the number of chain maintenance; It relies on self-flow lubrication, and the flow of lubricating oil is uncontrollable. It can only be controlled by feeling or observing the lubrication of the chain. This can easily cause uneven lubrication of the chain, insufficient lubrication, and easy damage to the chain. Transitional lubrication not only wastes resources, but also Cause corrosion to the conveyor belt, reduce friction and affect unloading efficiency and other hidden dangers; third, it needs to stop for lubrication, and the driver usually opens the lubrication switch valve, which affects the normal use of the self-unloading semi-trailer

Through the analysis of the existing technical means, it can be seen that the existing lubrication and maintenance methods have the problems of untimely lubrication and poor lubrication effect
