Abstract

The invention specifically refers to a fully mechanized mining working face two-end excess elevation segment hydraulic supporting device, and solves the problems that an existing excess elevation support needs personnel high altitude construction, thus wasting mass materials; the fully mechanized mining working face two-end excess elevation segment hydraulic supporting device comprises two hydraulic stretching racks arranged in parallel and fixed by a U-shape channel steel on an existing support; the hydraulic stretching rack comprises a rear fixed bearer and a front fixed bearer; an overturn oil cylinder is hinged to a position in front of the rear fixed bearer; an overturn beam is hinged above the front fixed bearer; the front end of the overturn oil cylinder is hinged to the middle portion of the overturn beam; a lifting oil cylinder is fixed above the overturn beam; the front end of the lifting oil cylinder is hinged to a horizontally arranged support plate; the middle portion of the overturn beam is hinged to a support oil cylinder; the front end of the support oil cylinder is hinged to the support plate. An excess elevation segment can be safely passed with high efficiency, thus reducing construction difficulty, and saving construction cost; the hydraulic supporting device is simple in operation, easy to master, can be repeatedly used, and is long in life.

Description

technical field [0001] The invention relates to a coal mine roadway support technology, in particular to a hydraulic support device for a superelevation section at both ends of a fully mechanized mining face. Background technique [0002] At present, during the mining process of the fully mechanized mining face of coal mines, the inlet and outlet air troughs often encounter super-high sections, and the height of the roadway reaches more than 4 meters, which is difficult to maintain. When the wooden piles are connected to the top and the two ends of the fully mechanized mining face are pushed forward, the method of using the front beam of the bracket to hold the shed beams is used to pass through the super-high section. Lots of wood, and time consuming. Contents of the invention [0003] The present invention provides a hydraulic support device for crossing superelevation sections at both ends of a fully mechanized mining face in order to solve the problems that the existi...
