Abstract

The invention discloses an adjusting device for an engineering hydraulic support and relates to the technical field of engineering equipment. The device includes a support plate and a self-locking universal wheel mounted at a lower surface of the support plate, wherein an upper surface of the support plate is fixedly connected with a hollow case, the hollow case is internally equipped with a transmission device, an output shaft of the transmission device is fixedly connected with a receiving roller, the receiving roller is wound with a connection belt, an outer side of the support plate is provided with a rotation handle, the support plate is fixedly connected with a height adjusting device, a top end of the height adjusting device is fixedly connected with a displacement adjusting device,the support plate is fixedly connected with a sliding rail, and two ends of the sliding rail are fixedly connected with limit blocks. The connection belt can only be wound or unwound through rotationof the receiving roller, however, the connection belt cannot be used as a driving end to make the receiving roller rotate, a hydraulic bracket can be made to rotate around a hinge point of the connection belt and the mounting plate to achieve limiting, and adjusting the pitch angle of the hydraulic bracket is convenient.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to an adjusting device for engineering hydraulic supports. Background technique [0002] The hydraulic support is the main equipment of the comprehensive mechanized working face in coal mining. It can reliably and effectively support and control the roof of the working face, isolate the goaf, and maintain a safe underground working space. The hydraulic support cooperates with the shearer, the flexible conveyor and the trough loader to form a comprehensive mechanized equipment for the mining face, thus creating conditions for high-yield, high-efficiency and safe production in underground coal mining. The hydraulic support is a structure used to control the mine pressure of the coal mining face. Mining face mine pressure acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surround...
