Abstract
The utility model discloses a kind of novel return airway advance timbering, comprise unsplit bedplate and integral top beam, the middle part of integral top beam is provided with cross head pin joint, be respectively equipped with column between the front and rear of integral top beam and unsplit bedplate, between cross head pin joint and the rear portion of unsplit bedplate, be provided with caving shield.Front and rear front and back symmetrical structure centered by cross head pin joint of integral top beam is arranged.The front end of integral top beam, rear end and both sides are respectively equipped with skirting board.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.The irregular working condition of roadway floor can be adapted to, can increase and protect top area, protection personal security.
Description
Technical field
The utility model relates to a kind of coal mine hydraulic supporting, particularly relates 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.
Utility model content
The purpose of this utility model is to provide strong, the adaptable novel return airway advance timbering of a kind of stability.
The purpose of this utility model is achieved through the following technical solutions:
Novel return airway advance timbering of the present utility model, 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.
The technical scheme provided as can be seen from above-mentioned the utility model, the novel return airway advance timbering that the utility model embodiment 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 utility model embodiment below.
Novel return airway advance timbering of the present utility model, 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 utility model, 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 utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
