Abstract
The invention discloses an anti-slide mechanism for the top beam of a hydraulic support. The anti-slide mechanism comprises the top beam, wherein a plurality of anti-slide ledges are transversally fixed on the upper surface of the top beam; the material of the anti-slide ledges is hot-rolled equilateral angle steel with a specification of 100*100*12; the distances among the plurality of anti-slide ledges are 800 mm. During the lifting of a support, a vertical column continues to ascend after the top beam contacts with a coal seam roof, thus the anti-slide ledges at the uppermost ends of the top beam and the roof are wedged in the a coal seam roof layer; the top beam of the support is fixed on the coal seam roof, and the support is prevented from sliding forwards due to a forward pull force, thus realizing an anti-slide function, and achieving slide prevention for the single support during use.
Description
Technical field
The present invention relates to a kind of coal mine work area hydraulic support, relate in particular to a kind of hydraulic support top beam anti-slipping mechanism.
Background technology
At present, anti-skidding mostly being between adjacent frame of coal mine work area hydraulic support connects, and by mutual pulling force, plays anti-skidding object, and the anti-skidding blank that is at home and abroad of single support.
Summary of the invention
The hydraulic support top beam anti-slipping mechanism that the object of this invention is to provide a kind of simple in structure, good antiskid effect.
The object of the invention is to be achieved through the following technical solutions:
Hydraulic support top beam anti-slipping mechanism of the present invention, comprises back timber, the upper surface of back timber be laterally fixed with many anti-skidding stupefied.
As seen from the above technical solution provided by the invention, the hydraulic support top beam anti-slipping mechanism that the embodiment of the present invention provides, due to the upper surface of back timber be laterally fixed with many anti-skidding stupefied, when support rises, after back timber contacts with roof, column continues to rise, make back timber top board anti-skidding stupefied wedging roof layer topmost, set cap is fixed on roof, prevents that pulling force forward from making support to front slide, plays the anti-skidding use of doing.
Accompanying drawing explanation
The structural representation of the hydraulic support top beam anti-slipping mechanism that Fig. 1 provides for the embodiment of the present invention.
In figure: 1, back timber, 2, back timber side guard board, 3, anti-skidding stupefied.
The specific embodiment
To be described in further detail the embodiment of the present invention below.
Hydraulic support top beam anti-slipping mechanism of the present invention, its preferably the specific embodiment be:
Comprise back timber, the upper surface of back timber be laterally fixed with many anti-skidding stupefied.
Described anti-skidding stupefied material is that specification is the hot rolling equal angle steel of 100X100X12.
Described many anti-skidding stupefied spacing are 700mm-900mm.
Described many anti-skidding stupefied spacing are 800mm.
Hydraulic support top beam anti-slipping mechanism of the present invention, improved the structure of back timber and top board contact surface, when support rises, after back timber contacts with roof, column continues to rise, and makes back timber top board anti-skidding stupefied wedging roof layer topmost, set cap is fixed on roof, prevent that pulling force forward from making support to front slide, play the anti-skidding use of doing, solve in use anti-skidding of single support.
Specific embodiment:
As shown in Figure 1, anti-skidding stupefied 3 material is that specification is the hot rolling equal angle steel of 100X100X12, anti-skidding stupefied 3 are fixed by welding on back timber 1, spacing on the upper back timber of anti-skidding stupefied 3 welding is 800mm, when support rises, after back timber contacts with roof, column continues to rise, make back timber top board anti-skidding stupefied wedging roof layer topmost, set cap is fixed on roof, prevents that pulling force forward from making support to front slide, plays the anti-skidding use of doing, both can solve in use anti-skidding of single support, again can be for a plurality of supports anti-skidding.
Hydraulic support top beam anti-slipping mechanism of the present invention, be applied to fixedly withdraw on the support of winch, the support that fixedly withdraws winch mostly is single or two one group application, in rack restoring process, withdraw hydraulic support and make winch have forward a slip to the pulling force of winch, at this moment just need the support that fixedly withdraws winch to have anti-slipping mechanism anti-skidding.Hydraulic support top beam anti-slipping mechanism of the present invention is by improving the pattern of back timber and top board contact surface, realize anti-skidding between back timber and top board, fill up the anti-skidding blank at home and abroad of single support, when the single application of hydraulic support, had very large promotion prospect and development space.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
