Multipurpose integrated hydraulic function valve group

Abstract

The invention relates to the technical field of hydraulic systems of coal mine fully mechanized coal mining face transportation equipment, in particular to a multipurpose integrated hydraulic function valve group. The multipurpose integrated hydraulic function valve group comprises a main valve liquid distribution block, an embedded chain tightening motor function valve block, an embedded telescopic tail function valve block, an embedded lubricating device function valve block and an embedded cooling water system function valve block, the embedded chain tightening motor function valve block, the embedded telescopic tail function valve block, the embedded lubricating device function valve block and the embedded cooling water system function valve block are sequentially embedded into the main valve liquid distribution block from left to right in an embedded mode, a high-pressure liquid inlet, a high-pressure liquid return opening and a high-pressure liquid drainage opening are formed in the left side of the main valve liquid distribution block, a cooling water liquid inlet, a cooling water liquid return opening and a cooling water drainage opening are formed in the right side of the main valve liquid distribution block, four sets of electromagnetic pilot valves with the end faces connected are arranged on the upper surface of the main valve liquid distribution block so as to drive the corresponding function valve blocks to execute actions, and a corresponding connecting pipeline is arranged in the main valve liquid distribution block. The valve group is ingenious in design and reasonable in structure, and can effectively solve the problem that the number of hydraulic pipelines is large and the hydraulic pipelines are miscellaneous in the working environment of an underground coal mine.

Description

technical field [0001] The invention relates to the technical field of the hydraulic system of the transport equipment of the coal mine fully mechanized mining face, in particular to a multi-purpose integrated hydraulic function valve group. Background technique [0002] Scraper conveyor is one of the main equipment in fully mechanized mining face. Usually, the scraper conveyor realizes tightening the chain when starting up and loosening the chain when stopping through the action of the telescopic tail, so as to ensure the normal meshing or disengagement of the scraper chain and the sprocket, and to protect the chain; the lubrication device plays a role in protecting the chain. Lubrication of bearing components; during the working process, the cooling system of the conveying equipment can effectively reduce the temperature of the motor and reducer to ensure the reliable and safe operation of the transmission device; during the chain cutting and connecting process, the convey...

AI Technical Summary

Problems solved by technology

[0003] In the traditional method, the retractable tail, the hydraulic chain tightening system and the lubricating device are all realized by the hydraulic control system installed in different positions, and the cooling system is controlled by the electric ball valve, and the above mentioned four The hydraulic control system is scattered in installation and layout, resulting in many and miscellaneous liquid inlet and return pipelines and control pipelines, and the site layout is chaotic

In the working environment of coal mines, there are many and miscellaneous hydraulic pipelines, which will lead to many hidden troubles in the hydraulic control system, and there is a certain difficulty in troubleshooting
