Abstract

The invention discloses a top plate mechanism of a hydraulic support. The top plate mechanism comprises a support base and a mounting plate. A supporting block and a fixing block are arranged on the mounting plate, and a first jack is obliquely arranged on the side face of the right side of the supporting block. An auxiliary strut is hinged to the top end of the first jack, and the bottom end of the auxiliary strut is hinged to the fixing block. A supporting strut is hinged to the upper portion of the auxiliary strut, and a second jack is hinged to the lower side face of the supporting strut.The bottom end of the second jack is connected to the mounting plate, and the top end of the supporting strut is connected with a top plate mounting plate. A top plate body is connected to the upper portion of the top plate mounting plate. The left side face and the right side face of the top plate body are connected with a first auxiliary plate and a second auxiliary plate through two first springs, a first supporting adjusting assembly is arranged below the first auxiliary plate, and a second supporting adjusting assembly is arranged below the second auxiliary plate. The conception is ingenious, the structure is compact and reasonable, self-adjusting performance is high, it is ensured that the top faces of the top plate body, the first auxiliary plate and the second auxiliary plate makefull contact with the working face, and supporting is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a roof mechanism of a hydraulic support. Background technique [0002] In coal mining, the hydraulic support plays a key role in side support. The working environment of the hydraulic support is uneven. When the roof encounters a working surface with a certain slope or radian when it is supported, the contact between the roof and the working surface is not complete. Contents of the invention [0003] The purpose of the present invention is to provide a roof mechanism of a hydraulic support, which solves the problem of incomplete contact of the roof fixing structure in the prior art when encountering slopes or radian working surfaces. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A roof mechanism of a hydraulic support in the present invention comprises a suppor...
