Embodiment Construction

[0017] according to Figure 1~4 The specific structure of the present invention will be described in detail. The telescopic timely support device for excavation includes components such as a hydraulic column 1, a beam supported by the column head of the hydraulic column 1, and a running beam assembled on the beam. The bottom of the hydraulic column 1 is provided with independent bases 22 connected to the hydraulic system 19 to prevent the hydraulic column 1 from sinking into the floor. The hydraulic system 19 is fixed by components such as the valve group bracket 18 . Above-mentioned crossbeam comprises front crossbeam 4, middle crossbeam 5, back crossbeam 6, main support crossbeam 7 and auxiliary support crossbeam 8 arranged in parallel to each other; Following beam 12, rear elastic following beam 13, front rigid following beam 14, middle rigid following beam 15, rear rigid following beam 16 and edge rigid following beam 17 etc. parts. The front elastic girder 11 , the mid...

Abstract

The invention discloses a telescopic tunneling immediate support device, which effectively solves the problem of unavailable continuous roof contact or poor roof contact capability existing in the prior art during use. The support device comprises hydraulic upright posts, beams and longitudinal beams, and is characterized in that: the bottom of each hydraulic upright post is provided with a base;the beams comprise a front beam, a middle beam, a rear beam, a main support beam and an auxiliary support beam which are arranged in parallel with one another; the longitudinal beams comprise a frontelastic longitudinal beam, a middle elastic longitudinal beam, a rear elastic longitudinal beam, a front rigid longitudinal beam, a middle rigid longitudinal beam, a rear rigid longitudinal beam and a side rigid longitudinal beam which are arranged in parallel with one another and are vertical to the beams; a push hydraulic cylinder is hinged between every two beams respectively; and the elastic longitudinal beams and the rigid longitudinal beams are fixed on corresponding beams respectively, inserted in limiting guide sleeves of corresponding beams and driven to move along the limiting guidesleeve in a reciprocating way by the beams. The support device has the advantages of reasonable structural distribution, convenience for adjusting continuous roof contact, stable supporting and capabilities of improving the operating environment of workers, better meeting the requirement on matching job of an underground laneway support and a roadheader and remarkably improving the support quality and tunneling operation efficiency of a laneway top plate.

Description

technical field [0001] The invention relates to an improved temporary support device for roadway excavation, in particular to a timely support device for excavation which adopts a composite telescopic top beam mechanism and a flexible top connection mechanism. It belongs to the field of mining machinery manufacturing and application. Background technique [0002] At present, with the widespread use of comprehensive mechanized roadheaders (referred to as "mechanized roadheaders"), the efficiency of roadway excavation has been greatly improved compared with the traditional "drilling and blasting" operation method. With the mining of coal mines year by year, the depth of the coal seam is getting deeper and deeper, so the overall load of the rock on the roof of the roadway has a tendency to increase gradually. Due to the increase of the rock load and the relatively developed roof, it is bound to not allow a large area of ​​empty roof (even if there is a temporary There is also ...
