Description

Hydraulic supporting device for coal mining tunnel Technical Field The utility model relates to the technical field of roadway support, in particular to a hydraulic support device for a coal mining roadway. Background The hydraulic support for the integral top beam of the coal mining working face is core equipment for supporting the coal mining fully-mechanized working face, and the integral top beam is directly connected with the top through the support of a hydraulic upright post to provide stable and uniform supporting force for directly pushing rock strata above the coal mining working space. The coal mine working face support disclosed in the prior patent publication No. CN222576697U comprises a hydraulic support base, wherein the top of the hydraulic support base is horizontally connected with a transverse top plate through a hydraulic cylinder, the transverse top plate is arranged right above the hydraulic support base, one side of the top of the hydraulic support base is provided with an inclined top plate through a connecting rod, the transverse top plate is rotationally connected with the inclined top plate through a pin, the inner walls of two sides of a gap above the hydraulic support base are respectively and fixedly provided with a synchronous motor, the power output end of one synchronous motor is fixedly welded with a first driving turntable, the power output end of the other synchronous motor is fixedly welded with a second driving turntable, a driven turntable is arranged between the first driving turntable and the second driving turntable, the first driving turntable, the driven turntable and the second driving turntable are driven by the synchronous motor, and the first crushing hydraulic cylinder and the second crushing hydraulic cylinder are respectively rotationally arranged on a rotating shaft arranged in the middle, so that the first crushing hydraulic cylinder and the second crushing hydraulic cylinder can be alternately jacked upwards and knock a coal bed at a high position after the motor is started, and the coal mine is crushed. Among the above-mentioned support, directly jack-up beats the coal seam, and the knocking direction perpendicular to roof leads to broken coal cinder to scatter all around because of gravity and impact force, and scattered coal cinder piles up around the hydraulic support bottom, probably blocks the contact surface of base and tunnel bottom plate, leads to the support resistance increase when adjusting or remove, influences the use of support.
