Description
Technical Field
The utility model belongs to the mining equipment field especially relates to a mining flatbed for withdrawing hydraulic support.
Background
The hydraulic support is a structure used for controlling the mine pressure of the coal face. The mining face mine pressure acts on the hydraulic support in the form of external load. In the mechanical system of the interaction of the hydraulic support and the mining face surrounding rock, if the resultant force of all the supporting pieces of the hydraulic support and the resultant force of the external load of the top plate acting on the hydraulic support are exactly in the same straight line, the hydraulic support is very suitable for the mining face surrounding rock. The support is supplied with liquid by an emulsion pump station arranged in a roadway or a chamber. After the pressure emulsion enters the upright post through the control system, the support raises the primary support top plate, the support resistance of the support to the top plate is increased along with the sinking of the top plate, the pressure of the locking liquid in the upright post is limited by the safety valve, and the constant-resistance support is realized. When the support is moved, the vertical column is firstly reduced to enable the support to be unloaded and separated from the top plate, then the jack is moved, the support is moved by taking the conveyor (or an adjacent support and the like) as a fulcrum, and then the conveyor is moved by taking the supported support as the fulcrum. The support can also realize various auxiliary actions such as side protection, balance, support adjustment and the like through various jacks, thereby realizing comprehensive mechanization of coal dropping, supporting and transportation of a working face by matching with a coal mining machine and a scraper conveyor. The hydraulic supports are arranged on the working face at a certain interval, most of the hydraulic supports move sequentially, and the other hydraulic supports move in a segmented or alternate mode.
The flat car is an electric rail factory transportation vehicle. Also known as electric flat cars, trolleys and straddle carriers. The device has the advantages of simple structure, convenient use, easy maintenance, large bearing capacity, less pollution and the like. The crane is widely used in machine manufacturing and metallurgical plants, and is used for transporting heavy objects to pass through in cooperation with a crane inside a workshop.
