Abstract
The invention discloses a novel air return way advance support. The novel air return way advance support comprises an integrated base and an integrated top beam. A cross head hinge joint point is arranged in the middle of the integrated top beam. Stand columns are arranged between the front portion of the integrated top beam and the integrated base and between the rear portion of the integrated top beam and the integrated base respectively. A covering beam is arranged between the hinge joint point of the integrated top beam and the rear portion of the integrated base. The front portion and the rear portion of the integrated top beam are arranged into a front and back symmetrical structure with the cross head hinge joint point as the center. Wall protection plates are arranged at the front end, the rear end and the two sides of the integrated top beam respectively. Multiple novel air return way advance supports are sequentially arranged in an air return way in a front and back mode. The integrated bases of every two adjacent supports are connected through a push-pull oil cylinder. The novel air return way advance support can adapt to the working condition that a bottom plate of a roadway is not smooth, the top protection area can be enlarged, and the personnel safety is protected.
Description
Technical field
The present invention relates to a kind of coal mine hydraulic supporting, particularly relate to a kind of novel return airway advance timbering.
Background technology
At present, along with the universal of coal mining mechanization and the attention to navigation channel supporting safety, leading chock for drift is more and more applied in Modern Pit.
As shown in Figure 1 and Figure 2, in prior art, the return airway advance timbering of common form is left and right frame form, is made up of anchor frame and side arm and after-frame, side arm and after-frame are all front and back split articulated structures, are in use controlled the direction of travel of support by the anchor frame in front.This support return aircourse top board and base plate situation good time service condition better, if that set cap will be caused to connect top is bad in back out-of-flatness, structure stress is uneven, and section structural can be caused time serious to damage.If roadway floor injustice will cause the crooked of left and right frame, be not steady on one's legs, support can be caused time serious to lodge, affect the normal production order.
Summary of the invention
The object of this invention is to provide strong, the adaptable novel return airway advance timbering of a kind of stability.
The object of the invention is to be achieved through the following technical solutions:
Novel return airway advance timbering of the present invention, comprise unsplit bedplate and integral top beam, the middle part of described integral top beam is provided with cross head pin joint, be respectively equipped with column between the front and rear of described integral top beam and described unsplit bedplate, between described cross head pin joint and the rear portion of described unsplit bedplate, be provided with caving shield.
As seen from the above technical solution provided by the invention, the novel return airway advance timbering that the embodiment of the present invention provides, owing to comprising unsplit bedplate and integral top beam, the middle part of integral top beam is provided with cross head pin joint, column is respectively equipped with between the front and rear of integral top beam and unsplit bedplate, caving shield is provided with between the rear portion of cross head pin joint and described unsplit bedplate, base and back timber adopt integral form, it is larger that base connects floor space, floor pressure ratio Air holder is little, can adapt to the irregular working condition of roadway floor.

Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
Novel return airway advance timbering of the present invention, its preferably detailed description of the invention be:
Comprise unsplit bedplate and integral top beam, the middle part of described integral top beam is provided with cross head pin joint, be respectively equipped with column between the front and rear of described integral top beam and described unsplit bedplate, between described cross head pin joint and the rear portion of described unsplit bedplate, be provided with caving shield.
Described cross head pin joint is provided with two orthogonal hinges, and the hinge horizontally set on top is also hinged with the middle part of described integral top beam, the hinge of bottom longitudinally arrange and with the upper end thereof of described caving shield.
Front and rear front and back symmetrical structure centered by described cross head pin joint of described integral top beam is arranged.
The front end of described integral top beam, rear end and both sides are respectively equipped with skirting board.
The bottom of described caving shield is connected with the rear portion of back link with described unsplit bedplate by front rod.
This novel return airway advance timbering has before and after multi rack in return airway to be arranged successively, is connected between the unsplit bedplate of adjacent support by push cylinder.
Specific embodiment:
As shown in Figure 3, Figure 4, novel return airway advance timbering of the present invention, base and back timber adopt integral form, and it is comparatively large that base connects floor space, and floor pressure ratio Air holder is little, can adapt to the irregular working condition of roadway floor.Integral top beam adds side skirting board all around, can increase and protect top area, protection personal security.
As shown in Figure 5, Figure 6, integral top beam and caving shield adopt cross head hinged, make set cap in use can the certain angle of deflection, can well adapt to the irregular working condition of back.Each support adopts four cylindricality formulas, and have good stability, lodging tolerance is stronger.
Return airway advance timbering of the prior art is all disintegrate to go into the well when going into the well, and assembles again, waste time and energy after being transported to down-hole.Novel advance timbering can adopt flat car entirety to go into the well due to good integrity, only need connect fluid pressure line and get final product normal operating use, save cost of labor after being transported to use location.
Return airway advance timbering of the prior art needs many people to coordinate carry out work when downhole operations, should control direction well to prevent support tilt again when action.Novel advance timbering a people can complete this work completely.
At present, this novel advance timbering, in Zhong Meidong slope colliery 922 job interview use, uses 1 year, obtains good result.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
