The empty shape sleeve inner of support beam bottom is found in Xiang Liang, guide beam insertion, and pillar, posts bottom support are further fixedly arranged on seat beam
On seat beam, the top braces of pillar are hinged in the pillar position of vertical support beam bottom, advancing jack with vertical support beam, buttress brace
With 2 vertical support beams of homonymy by erecting pin connection, and be fixedly connected by lateral pin with back timber, hydraulic means respectively with passage
Jack is connected with pillar by hydraulic valve piece with hydralic hose, and advancing jack and pillar are fitted with hydraulic valve piece.
Further, the structure of back timber is the rigid structure beam body of frame-type, several longerons and several crossbeams composition.
Further, the quantity for founding support beam is 4, and left and right is per each 2 of side.
Further, the quantity of pillar is identical with the quantity of vertical support beam, and each vertical support beam bottom is provided with 1 branch
Post.
Further, the quantity of advancing jack is preferably 4, each side 2, and 2 passage per side are very heavy
Top is arranged according to order up and down.
Further, it is preferable to the vertical guide beam quantity on seat beam is identical with the vertical support beam quantity per side.
Further, the hydraulic valve piece installed on advancing jack is hydraulic control reversible lock.
Further, the hydraulic valve piece installed on pillar is hydraulic control one-way valve.
The beneficial effect of excavation support of the present invention is：The operation of the equipment such as development machine can effectively be coordinated, carried in time
For the support of roadway support, so as to be smoothed out providing safeguard for colliery driving and back production；It is firm in structure, assembling side is installed
Just, can move.
