Abstract
The utility model relates to a rock burst working face hydraulic pressure bracket, which comprises side protecting plates and jacks, wherein the utility model is characterized in that very two jacks are of a pair and mounted on the same axes, every two of the side protecting plate directing rods are a pair two, mounted on the same axes and respectively connected with the side protecting plates, the bracket base is provided with two jacks and directing rods and connected on the outer side with a trapezoid skid resistance beam through the jacks and directing rods. The utility model can effectively adjust width of the bracket and prevent the bracket from being seized, blocked and knocked down. The utility model is improved in bracket adaptability and top beam stability, which prevents the bracket sliding downward. The bottom adjusting device realizes line-plane contact, which improves twist resistance of the skid resistance device and effectively prevents movement of the bracket base.
Description
Technical field: the utility model relates to and is used for large tilt angle compound mining fully mechanized coal face hydraulic support and transfers frame, anti-down, anti-skidding device, is a kind of relieve a garrison down hydraulic support of shoe of bilateral backplate and the end that has specifically.
Background technology: at present, the hydraulic support that large inclination working surface uses, the bracket side backplate is one-sided movable, anti-down anti-skid bracket device tie point mostly is articulated form, contact surface is a contact, it transfers frame, anti-down, shoe mainly to have following deficiency: 1, adjustable range is little, very easily squeezes, stings frame on the inclined plane, makes to transfer frame, moving difficulty.2, resistance to torsion is poor, and is fragile.When 3, support moved frame and transfers frame, anti-down, the shoe card of easily spraining produced support and twists poor stability.
The utility model content: the purpose of this utility model is to overcome the deficiency of above-mentioned technology, but provide a kind of can one-sided action again the dual-active side of bilateral action protect the accent rack device, to increase the frame scope of transferring.Set up defences down simultaneously at bracket base, shoe, the shoe contact point is the contact of line face, makes it stressed evenly, reduces tie point and turns round and refuse the reliability of increase anti-down anti-skid bracket.
The purpose of this utility model is achieved in that
A kind of hydraulic support comprises side guard board, jack, it is characterized in that per two of above-mentioned jack partners, and is contained on the same axis, and the side guard board guide peg also is per two and partners, and is contained on the same axis, links to each other with side guard board respectively; Establish two jack and guide peg in the bracket base, the bracket base outside is connected a trapezoidal anti-skidding beam by jack with guide peg.Core is to adopt the shoe of relieving a garrison down at the bottom of the bilateral dual-active side guard board band, and end accent device is located at the side of bracket base, acts on the adjacent frame.Cooperate with side guard board during use, form a kind of novel accent frame, anti-down, shoe.
The utility model device has the following advantages:
1, side guard board can be unidirectional or two-way simultaneous flexible, can regulate support width effectively, prevent that support stings frame, asphyxia by external pressure on the chest and abdomen and topple over.
2, strengthen the compliance of support and the closure of back timber, prevented inbreak between the bastard coal frame of top effectively.
3, on the adjacent frame of anti-skidding beam effect, make support on large inclination working surface, keep certain frame spacing.Prevented that not only support from gliding and asphyxia by external pressure on the chest and abdomen, and when moving frame, increased the stability of support, prevented from that support from gliding to topple over.
4, the end, transfer two jack cylinders of device to be interconnected, and makes its stress equalization, guarantees anti-skidding beam realization line, face contact, increased the resistance to torsion of shoe, prevents the bracket base displacement effectively.
5, end accent protects with side and transfers rack device to cooperate, and can realize in time transferring apace frame and move frame.
Description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 is Fig. 1 base vertical view
The specific embodiment: the back timber structure of selection and appropriate design, establish two groups of jack (3) and guide peg (2) in two sides, per two jack are one group, be installed on the same axis, it is one group that the side guard board guide peg also is per two, be installed on the same axis, connect the side guard board (1) of both sides respectively.Establish two jack (5) and guide peg (6) in bracket base, the bracket base outside is connected a trapezoidal anti-skidding beam (4) by jack (5) with guide peg (6), transfers device at the bottom of the composition anti-skid.
Side guard board (1) gets final product one-sided action, but also bilateral moves simultaneously.Anti-skidding beam (4) is acted on the adjacent frame by jack (5) and guide peg (6) control.Anti-skidding beam is positioned at the support side, by anti-skidding beam two jack and guide peg is fused.
The end, transfer device to realize the right and left mutually changing installation according to advance of the face direction.
Claims (4)
1, a kind of fully mechanized coal face hydraulic support, transfer device at the bottom of comprising side guard board, jack and anti-skid, it is characterized in that per two of above-mentioned jack (3) partners, be contained on the same axis, the side guard board (1) that connects both sides respectively, side guard board guide peg (2) also is per two and partners, and is contained on the same axis, connects the side guard board (1) of both sides respectively; Transferring device at the bottom of the described anti-skid is to establish two jack (5) and guide peg (6) in bracket base, and the bracket base outside is connected a trapezoidal anti-skidding beam (4) by jack (5) with guide peg (6).
2, a kind of fully mechanized coal face hydraulic support as claimed in claim 1 or 2 it is characterized in that described side guard board (1) gets final product one-sided action, but also bilateral moves simultaneously.
3, a kind of fully mechanized coal face hydraulic support as claimed in claim 1 is characterized in that accent device of the described end can be according to the direction of propulsion right and left mutually changing installation of work plane.
4, a kind of fully mechanized coal face hydraulic support as claimed in claim is characterized in that the end two jack cylinders of accent device link.
