The described hydraulic vertical prop arranged in a crossed manner that mutually tilts in twos is two to arrange and put, and the upper end and the back timber of hydraulic vertical prop are hinged, and lower end and base are hinged; Described front-axle beam is provided with extensible canopy and the extensible canopy jack that is connected with extensible canopy; Described connecting plate mechanism is made of tail boom and connecting plate, and is hinged by jointed shaft between tail boom and the connecting plate, hinged with back timber in the connecting plate mechanism, down and base hinged; Described balance arm mechanism is made of balance arm and balance arm jack, and the balance arm jack is hinged by jointed shaft and balance arm, and is hinged with back timber in the balance arm mechanism, down and base hinged; Described hydraulic control valve module is located on the gap bridge case; Described push unit is located at the front end or the rear and front end of base.
The beneficial effects of the utility model:
1) support has been realized modularized design, can finish design back in the cylinder diameter module scope, carry out the trial-production of sample frame, the sample frame detect qualified after, cover the low clearance support with high trestle, loaded down with trivial details work such as design, the trial-production of sample frame, the sample frame that need not carry out each specification again detects, the evidence obtaining of peace mark, not only alleviated burden, also shortened the production cycle of manufacturing enterprise greatly to management work.
2) support can be realized the integrated package Assembling Production, and parts are made standard component, can form the dual forked type hydraulic support of differing heights specification according to the coal seam situation, in time satisfies the needs in colliery.
3) support can be accomplished scale production, and each parts can form production line, produces quickly and efficiently on a large scale realizing, reaches the purpose that satisfies colliery large-scale promotion hydraulic support, improves the level of China's coal-mine performing comprehensive coal mining machineryization with the fastest speed.
4) this support can be used in coal mine and adopt the overall height work plane next time, or is used in top-coal caving face, or is used in fully-mechanized mining working, or be used in blast mining face, or as light hydraulic support, or as medium-sized and heavy hydraulic support, or be used for the occasion that other needs roof timbering.It is simple and reasonable, performing comprehensive coal mining machineryization level height, and good stability, easy to use and reliable, have practicality widely.
