Problems solved by technology

[0010] The disadvantages of this structure are: the jack is an important component in the hydraulic support, which is expensive, and the push jack and the bottom lifting jack are set at the same time, and the cost of the support is high
[0012] This structure has the following problems: when the hydraulic support without bottom lifting jack moves forward, it will be affected by the resistance of the bottom plate, resulting in slow moving and lower production efficiency

Abstract

The invention provides a hydraulic support pushing mechanism, which comprises a base, a push rod, a telescopic part and a connecting plate, wherein the connecting plate is fixed on the base; a strip-shaped hole along the vertical direction is formed on the connecting plate; one end of the push rod is hinged with the telescopic part; the other end of the push rod is connected to a scraper conveyor; the other end of the telescopic part is arranged in the strip-shaped hole in a sliding mode; and an included angle is formed between the telescopic part and the push rod. The invention also provides a hydraulic support. According to the technical scheme, the functions of lifting and pushing can be realized by employing a lifting jack, the production cost of the support is saved, and the production effect of an enterprise is improved; and the linkage in the lifting and pushing processes can be realized, and the efficiency is improved.

Description

technical field [0001] The invention relates to machinery and equipment in the field of coal mining, and more specifically, to a hydraulic support pushing mechanism and a hydraulic support including the pushing mechanism. Background technique [0002] my country is the main coal-producing country in the world. The total number of coal mines exceeds the sum of the number of coal mines in all other countries in the world. Comprehensive mechanized coal mining has also become the main method of mining coal seams. [0003] The hydraulic support is the support equipment for comprehensive mechanized coal mining. Its main function is to support the roof of the stope, maintain the working space of the shearer and scraper conveyor, and move forward with the mining and transportation equipment on the working face. The front end of the moving frame of the thin coal seam hydraulic support is generally connected with scraper conveyor and other equipment to realize comprehensive coal minin...
