The utility model discloses the greater part subunit that well end hydraulic support utilized traditional end hydraulic support is as the basis, through install the range of coming increase shielding roof beam liftable with the dais additional between connecting rod and base to make the bearing height of each section back timber must ether high, thereby adapt to the requirement of new working face crossheading height, consequently the utility model provides a high not enough condition of rising of back timber among the prior art.
Description
Technical field
This utility model relates to a kind of end hydraulic support.
Background technology
At present, mining end hydraulic support is arranged in tunnel and work surface intersection, in order to supporting termination top board, provides sufficient arrangement space for termination fully-mechanized mining equipment and hydraulic power unit and power distribution station etc., and completes roadway roof coal and put coal operation, it is achieved termination mechanization.The existing end hydraulic support such as Chinese patent literature CN202467882 U(day for announcing is on October 3rd, 2012) disclosed " three one group of frame face end supports ", including base and on the back timber that supported by hydraulic vertical prop, back timber has two joints, and it is the most hinged, hydraulic vertical prop between each joint back timber and base all has two groups and time interval, the rear end of back timber is hinged with caving shield, caving shield passes through on the two groups of rod hinge connections of time interval crotch platform on rear side of base, with under the thrusting action of hydraulic vertical prop, termination top board is held out against on the end face in tunnel by back timber, realize the support to tunnel end face.But usually owing to being actually needed in coal production; return airway height often changes, and highly increases above original end hydraulic support bearing height allowed band, causes existing equipment to use; generally require redesign, manufacture new end hydraulic support, cause the waste of resource.
Utility model content
The purpose of this utility model is to provide a kind of end hydraulic support, it is intended to solve the situation that in prior art, the wicking height of back timber is not enough.
In order to realize object above, in this utility model, the technical scheme of end hydraulic support is as follows:
End hydraulic support, including hydraulic prop below each back timber of the most hinged back timber, respectively support and the base that is connected to hydraulic prop lower end, the top beam rear end of final section is hinged with caving shield, the rear end of caving shield is hinged with connecting rod, it is equipped with between connecting rod and base and adds dais, the bottom adding dais is connected on base, and the bottom at the top and connecting rod that add dais is hinged.
The rear side of base is convexly equipped with crotch platform, and crotch platform is provided with the base connecting hole being added dais by stud connection, adds the top of dais and is provided with and increases connecting hole by stud connection connecting rod, and the shape increasing connecting hole is identical with the aperture of base connecting hole.
The list group hydraulic prop support that the most previous joint back timber is alignd by left and right and is parallel to each other, and it is equipped with oscillating arm mechanisms between the most previous joint back timber and base, oscillating arm mechanisms includes the upper pendulum bar being hinged on the downside of back timber and the draft link being hinged on base, and the lower end of upper pendulum bar is hinged with the upper end of draft link.
Before oscillating arm mechanisms is in hydraulic prop.
In oscillating arm mechanisms, upper and lower fork forms folding chevron, and the tip of chevron is forward.
Based in this utility model, end hydraulic support utilizes most of parts of tradition end hydraulic support, the liftable amplitude of caving shield is increased by installing dais between connecting rod and base additional, so that respectively the bearing height of joint back timber can obtain ether height, thus adapt to the requirement of new return airway height, the situation that during therefore this utility model solves prior art, the wicking height of back timber is not enough.
