Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a support for a coal mine, including a mounting base 1, an oil cylinder 2 is disposed in the mounting base 1, a piston rod 3 of the oil cylinder is fixedly connected to a support column 4, and a baffle 5 is fixedly connected to the top of the support column 4; a bottom plate 6 is arranged below the mounting seat, sliding grooves 7 are formed in two sides of the bottom plate 6, and sliding blocks 8 are arranged in the sliding grooves 7; 1 both sides of mount pad are provided with first hinge support 9, the one end that two sliders 8 are relative all is provided with second hinge support 10, still includes two bracing pieces 11, two 11 both ends of bracing piece are articulated with first hinge support 9 and second hinge support 10 respectively.

As the utility model discloses preferred technical scheme, furtherly, 1 bottom of mount pad is provided with pricks ground pole 12, prick ground pole 12 bottom and be the circular cone type, be provided with through-hole 13 with pricking ground pole 12 correspondence on the bottom plate 6, prick ground pole 12 and arrange through-hole 13 in, under 2 reverse actions of hydro-cylinder, prick ground pole 12 and can follow through-hole 13 and prick the underground.

As the embodiment of the utility model provides a preferred technical scheme, furtherly, 7 bottoms of spout are provided with the pinhole and are used for plug fixed pin 14, and fixed pin 14 is used for restricting the removal of slider 8 in spout 7, refer to fig. 1, and slider 8 can not remove in spout 7, then mount pad 1 can not realize displacement from top to bottom yet.

By adopting the technical scheme, the working process of the embodiment is realized as follows: at first use fixed pin 14 to remove slider 8 and carry on spacingly, at this moment, prick ground pole 12 bottom insert in the through-hole 13 and with the bottom surface contact, start hydro-cylinder 2, hydro-cylinder piston rod 3 drives support column 4 and shifts up, with baffle 5 and tunnel top butt, because fixed pin 14 limiting displacement, mount pad 1 does not take place to remove, later pull out fixed pin 14, hydro-cylinder 2 uses the tunnel top as the basic point, reverse 1 drive of mount pad of pushing down pricks ground pole 12, make prick ground pole 12 prick the underground gradually, slider 8 slides to the outside in spout 7 in step. The supporting rod 11 supports the mounting seat 1, and the mounting seat 11 is displaced in the vertical direction without toppling through the design of the sliding block 8 of the sliding chute 7.

As the preferred technical solution of the embodiment of the present invention, further, the baffle 5 is trapezoidal, and the buckling strips 15 are fixed on both sides of the upper end surface thereof.

Through adopting above-mentioned technical scheme, detain strip 15 and when baffle 5 was moved up by oil cylinder piston rod 3 drive support column 4, pricked the tunnel top, made baffle 5 be connected more firmly with the tunnel top, strengthened the support effect.

As a preferable technical solution of the embodiment of the present invention, further, a triangular reinforcing rib plate 16 is fixed between the baffle 5 and the supporting column 4.

Through adopting above-mentioned technical scheme, the stability of rib 16 reinforcing baffle 5 improves its support effect, and simultaneously, rib 16 makes baffle 5 both sides also can be by fine support, avoids causing baffle 5 both sides to take place to bend the deformation downwards because of middle part stress concentration, improves its life.

To sum up, the utility model discloses a control cylinder piston rod drives the baffle in the adjustment of direction of height, makes to strut and to be applicable to the not colliery tunnel of co-altitude, simultaneously under the reverse action of hydro-cylinder, makes to prick the ground pole and prick in the underground, makes to strut and has good firm effect, the utility model discloses simple structure, design benefit does not need other fixed knot to construct the outrigger that can realize strutting.
