Abstract
The utility model discloses a composite metal support of a mine large-section roadway shoring, which belongs to the technical field of machinery. The composite metal support mainly consists of an arch-shaped support and a door-shaped support, and the arch-shaped support is disposed on the door-shaped support. The door-shaped support is formed by that upright columns disposed symmetrically are respectively provided with transverse beams, the outer ends of the transverse beams are respectively provided with oblique supporting blocks, the transverse beams are respectively provided with limiting blocks, and the two transverse beams are connected through U-shaped steel clamp cables. The composite metal support has the advantages that the composite metal support is reasonable in structure, simple in processing, fine in supporting effect and particularly adaptable to large-section roadway shoring.
Description
Technical field
The utility model relates to a kind of suspension device of mining tunnel, and specifically a kind of composition metal support of mining large section roadway supporting belongs to field of mechanical technique.
Background technology
That colliery metallic supports in galleries form commonly used is generally is trapezoidal, arch, circle etc., and its material is generally mining i beam and U shaped steel.Common U shape steel bracket is colliery a kind of rack form commonly used, and it is with the side pressure on arc support beam cross binding both sides, with the vertical roof supporting pressure of bracket upright post.For the tunnel of conventional section, adopt general support can reach supporting effect preferably, but for heavily stressed large section roadway (cross-sectional area 18m
2More than), because top board and rock stratum, both sides exposed area are bigger, the stressed also corresponding increase of rack beams and rack leg, if still adopt conventional support to carry out supporting, the length dimension of rack beams and bracket upright post is bigger, bending resistance and twisting resistance obviously weaken, and support breakoff phenomenons such as skew, press-bending, distortion will occur in the short period of time, is difficult to reach supporting effect preferably.
The utility model content
Task of the present utility model provides a kind of rational in infrastructure, and processing is simple, the composition metal support of the mining large section roadway supporting that supporting effect is good.
For realizing above-mentioned task, technical solution of the present utility model is:
A kind of composition metal support of mining large section roadway supporting mainly is made of arch support and portal trestle, and arch support is arranged on the portal trestle.
The composition metal support of described a kind of mining large section roadway supporting, its portal trestle is by being provided with crossbeam respectively on the symmetrically arranged column, and the crossbeam outer end is provided with the bearing diagonal piece respectively, and limited block is set respectively on the crossbeam, and two crossbeams connect and compose by U shaped steel card cable.
The utlity model has rational in infrastructurely, processing is simple, and supporting effect is good, especially is suitable for the advantage of large section roadway supporting.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of composition metal support of mining large section roadway supporting mainly is made of arch support 6 and portal trestle 7, and arch support 6 is installed on the portal trestle 7.Portal trestle 7 is by difference welding beam 3 on the mining i beam column 1 of a pair of symmetry, crossbeam 3 outer ends are welded bearing diagonal piece 2 respectively, difference welded limiting piece 4 on the crossbeam 3, after crossbeam 3 was shunk by side pressure, limited block 4 can play and increase the effect that resistance is spacing, prevent rack beam 3 continuation contractions.Two crossbeams 3 connect and compose by U shaped steel card cable 5.
Claims (2)
1. the composition metal support of a mining large section roadway supporting comprises arch support and portal trestle, and it is characterized in that: arch support is arranged on the portal trestle.
2. the composition metal support of a kind of mining large section roadway supporting according to claim 1, it is characterized in that: portal trestle is by crossbeam is set respectively on the symmetrically arranged column, the crossbeam outer end is provided with the bearing diagonal piece respectively, limited block is set respectively on the crossbeam, and two crossbeams connect and compose by U shaped steel card cable.
