Abstract

The invention provides a support device applied to coal mine mining face and excavation face operation, comprising n support mechanisms, where n is an integer ≥ 1, and the n support mechanisms are connected as a whole through pin shafts. Each support mechanism includes a support structure, and the support structure is arranged along the depth direction of the excavation working face. The support structure includes 2 sets of hydraulic prop assemblies. The top of the support structure is provided with 2 top beam structures, and each top beam structure is provided with a tow beam structure, and the tow beam structure is parallel to the top beam structure. The support mechanism also includes a telescopic sliding assembly, which is used to make the top beam structure and the trailing beam structure of the supporting structure slide relatively. The support device also includes a hydraulic control system, and the hydraulic control system includes a hydraulic prop assembly control pipeline and a telescopic sliding assembly control pipeline. The supporting device has the advantages of simple structure, high degree of automation, low labor cost, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of coal mine excavation support, in particular to a support device applied to coal mine mining face and excavation face operations. Background technique [0002] In recent years, with the continuous improvement of coal mining efficiency and the development of modern coal mine construction; at the same time, with the continuous improvement of the performance of fully mechanized excavation machinery and equipment, mechanical excavation has become the main direction of development. In coal mine excavation production operations 40 More than 100% of personal casualty accidents are roof accidents that occurred during the support of the working face. On this basis, the state has proposed various rules and regulations for coal mining, specifying the requirements of the national coal safety regulations, and strictly prohibiting open-top operations. [0003] Therefore, various supporting devices have appeared on the ...
