As the present invention, further scheme is: being connected between two pedestals using advancing jack.
As the present invention, further scheme is: being connected between two top beams using extensible canopy.
The beneficial effects of the invention are as follows overturning jack side guard plate can be driven to rotate at work, so that side guard plate
Angle change, to obtain more preferably protection effect；Multi-functional erosion control device have reasonable surrender resistance, deformational displacement,
Stiffness variable, intrinsic frequency, the erosion control performance for making bit rate and energy absorption ability etc. excellent, make bracket have self-protection and have
The function of effect control country rock realizes that erosion control effect provides important base for bracket.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is side view of the invention；
Fig. 3 is connection schematic diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, in the embodiment of the present invention, a kind of automatic moving type erosion control alley hydraulic support, including top beam 2 and pedestal
1, two multi-functional erosion control devices 3 are symmetrically connected on the pedestal 1, and multi-functional 3 top of erosion control device is fixedly connected with hydraulic vertical prop
4, the top and 2 downside of top beam of hydraulic vertical prop 4 are hinged；2 two sides of top beam are provided with side guard plate 10, side guard plate 10 and top beam
2 are hinged, and 2 lower surface of top beam is fixedly connected with mounting blocks 13, and the mounting blocks 13 are hinged with overturning jack 9, the overturning thousand
The free end on jin top 9 and the other side of side guard plate 10 are hinged；Mounting blocks 5, mounting blocks are also fixedly connected on the pedestal 1
Lower link 6 is movably hinged on 5,6 top of lower link is hinged with cant beam 7, is hinged on the downside of 7 top of cant beam and top beam 2；It is described
Upper connecting rod 8 is also hinged on mounting blocks 5,8 top of upper connecting rod is hinged with 7 lower part of cant beam, circular hole 14 is provided on side guard plate 10,
