Abstract
The invention discloses a small supporting point full-protection-type tunnel bracket and a supporting method thereof. The bracket comprises a stand column and a top beam, wherein a top beam cushion block is arranged above the top beam at a top pillar of the tunnel bracket; the contact point between the bracket top beam and a top plate is provided with a cushion block so as to decrease the direct supporting area of the bracket to the top plate and decrease the damage to the top plate when the bracket is early supported. When the top plate settles in the working process, the other area of the bracket top beam and a defending device can efficiently protect in order to maintain the top plate and ensure the safety. The bracket is supported with smaller earlier supporting force and big working resistance so as to decrease the damage to the tunnel top plate of the bracket and ensure the protection capability of the bracket to the tunnel.
Description
Technical field
The present invention relates to a kind of hydraulic support of colliery tunnel support, relate in particular to a kind of ramuscule support point full-protection-type tunnel bracket and supporting method thereof.
Background technology
In the prior art, at the down-hole coal excavation work plane, the down-hole is to the form of the artificial monomer column of the many employings of the supporting of crossheading supporting, and along with the propelling of coal-face, the underground labour constantly removes, supports individual prop; Perhaps, adopt advance timbering that gate road is carried out supporting.
Wherein, advance timbering cost height, need support and move frame repeatedly, big to the destruction of top board; And the supporting of monomer column to the support repeatedly of top board less, little, simple and practical to roof destruction, be widely used.
There is following shortcoming at least in above-mentioned prior art: monomer column supporting pretective acreage is little, poor stability, efficiency are low.
Summary of the invention
The purpose of this invention is to provide a kind of support repeatedly to top board less, little to roof destruction, and pretective acreage is big, safe, efficiency is high ramuscule support point full-protection-type tunnel bracket and supporting method thereof.
The objective of the invention is to be achieved through the following technical solutions:
Ramuscule support point full-protection-type tunnel bracket of the present invention comprises column, back timber, and the upper end of described column withstands on the needling of described back timber below, and the top of described back timber is provided with polylith back timber cushion block.
The supporting method of above-mentioned ramuscule support point full-protection-type tunnel bracket of the present invention, this support adopt the supporting way of little setting load, big working resistance in the supporting process.
As seen from the above technical solution provided by the invention, ramuscule support point full-protection-type tunnel bracket of the present invention and supporting method thereof are because the top of back timber is provided with polylith back timber cushion block.In the supporting process, the contact point of set cap and top board is a cushion block, reduces directly the top area of support to top board, and support is to the destruction of top board in the time of can reducing support just; And when crushing in the course of work, all the other areas of set cap and protector etc. can play effective protective action again, to safeguard top board and to guarantee safety.In the supporting process, adopt the supporting way of little setting load, big working resistance, both reduced the destruction of supporting, guaranteed the support capacity of support again the tunnel to back.
Description of drawings
Fig. 1 is the structural representation of ramuscule support point full-protection-type tunnel bracket of the present invention;
Fig. 2 a-Fig. 2 e is the arrangement schematic diagram of ramuscule support point full-protection-type tunnel bracket of the present invention.
The specific embodiment
Ramuscule support point full-protection-type tunnel bracket of the present invention, its preferable specific embodiment comprises column 2, back timber 3 as shown in Figure 1, and the upper end of column 2 withstands on the needling of back timber 3 belows, the lower end of column 2 is located on the base 1, and the top of back timber 3 is provided with polylith back timber cushion block 4.Back timber cushion block 4 can take different shapes.
Back timber cushion block 4 can be located at back timber 3 top positions of needling correspondence, also can be located at other position of back timber top.
The supporting method of above-mentioned ramuscule support point full-protection-type tunnel bracket of the present invention, its preferable specific embodiment are that this support adopts the supporting way of little setting load, big working resistance in the supporting process.
Shown in Fig. 2 a, 2b, 2c, 2d, 2e, this support can be single in the tunnel frame arrange that or two be to arrange before and after one group, or two be to arrange about one group, or three be to be arranged side by side about one group, or four is to be arranged side by side about one group etc.
The unit advance of this support can cut dark distance for 1-3 coal-winning machine.
The present invention is provided with the mode of cushion block above excavation support back timber needling place back timber top board, the contact point of set cap and top board is a cushion block, reduces directly the top area of support to top board, and support is to the destruction of top board in the time of can reducing support just.And when crushing in the course of work, all the other areas of set cap and protector etc. can play effective protective action again, to safeguard top board and to guarantee safety.
Support adopts the mode of little setting load, big working resistance, has both reduced the destruction of supporting to back, has guaranteed the support capacity of support to the tunnel again.
The arrangement of excavation support can adopt various ways, as single frame arrangement form, front and back frame form, about two brace type, three or four arrangement forms in left, center, right each other.
Unit advance can adopt one or more sections dark distances, and unit advance is big more, and excavation support is far away more apart to adjacent twice strong point of top board, and is more little to the destruction of support repeatedly of top board.
Excavation support of the present invention is in the supporting process, to back based on protection, auxilliary to be supported for, the suspension device of the band protector that realization can move certainly or control automatically, both kept the supporting of monomer column to the supporting less repeatedly of top board, the advantage little, overcome again that monomer column supporting pretective acreage is little, poor stability, shortcoming that efficiency is low roof destruction.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
