Description

Hydraulic support device for fully mechanized mining face

Technical Field

The utility model relates to a mining supporting machinery, especially a combine hydraulic support device who adopts working face.

Background

A hydraulic support device is also generally called a hydraulic support in coal mine application. The common hydraulic support consists of main parts such as a top beam, a base, a shield beam, an upright post, a pushing device, an operation control system and the like. In the coal production process of the coal face, in order to prevent the roof from falling, maintain a certain working space and ensure the safety of workers and the normal operation of each item, the roof must be supported. The hydraulic support is a device which uses liquid as power, is composed of a hydraulic element and a metal component and is used for supporting and controlling a top plate, and can realize a whole set of procedures of supporting, top cutting, frame moving, pushing a conveyor and the like. Practice shows that the hydraulic support has the advantages of good supporting performance, high strength, high support moving speed, safety and reliability. At present, hydraulic supports used in coal mines in China are various in types, and an end support and a middle hydraulic support are divided according to the installation position of a coal face of the support. The end hydraulic supports are called end supports for short and are specially installed at two ends of each coal face. The intermediate hydraulic support is a support that is mounted at a position on the coal face other than the face end. However, the hydraulic supports can be classified into a support type hydraulic support, a shield type hydraulic support, and a support shield type hydraulic support according to their functions. However, generally speaking, the hydraulic supports with different functions have different frame shapes and different support force distributions, so in order to reasonably select the frame shapes in use, the comprehensive analysis is actually carried out according to the actual situation of a fully mechanized mining face by combining the relationship between the support force and the bearing force of the supports, so that the support force of the supports can meet the requirement of roof load, which not only increases the application difficulty in the production process, but also does not have good effect on the support of special and complicated soft coal seams by the traditional three hydraulic supports.
