Abstract
The utility model relates to a big section hinged auxiliary beam of a metallic telescopic support, which is composed of a connecting piece, a U-shaped steel clamp, and an inclined strut, wherein, the connecting piece is fixed with a main beam of an existing metallic telescopic support; the U-shaped steel clamp is fixed with a leg of the metallic telescopic support; the inclined strut is respectively hinged with the connecting piece and the U-shaped steel clamp. The connecting piece fixed with the main beam can be a fixed block or a top beam fixed with the main beam via a fastening piece. When in use, the auxiliary beam is fitted with the existing metallic support to use; the bearing capacity and the stability of the whole support are enhanced; the requirement of the safety support of a large span mining roadway is satisfied; the using range of the existing metallic support is enlarged. The auxiliary beam of the utility model has the advantages of simple structure, reasonable structure, easy fabrication, and low cost.
Description
The utility model relates to the tunnel supporting arrangement under a kind of coal mine, is specially big section metal compressibile support radial type floor stringer.
Mine support is a very important aspect of mine production and construction, and the supporting quality directly has influence on the safety in production and the economic benefit of mine.Along with the raising and the expansion of comprehensive mining machinery degree, fully-mechanized mining equipment constantly maximizes, and causes the increase of drift section, and the ore deposit that causes the tunnel is pressed and to be manifested violent day by day, and the supporting capacity of existing metal compressibile support can not satisfy the needs of safety in production.At present, when running into section and be difficult to guarantee supporting quality more greatly, need under the brace summer of existing support, prop up the post of setting up an office again, like this, the one, increased support cost, the 2nd, influenced the utilization rate of drift section, and its maintenance situation in tunnel is unsatisfactory, and maintenance capacity is very big.
The purpose of this utility model is for providing a kind of big section metal compressibile support radial type floor stringer.
The utility model is to adopt following measure to realize: the connector that this radial type floor stringer is connected firmly by the girder with existing metal compressibile support, with the fixing U shaped steel card of the canopy leg of metal compressibile support with constitute with the hinged diagonal brace of connector and U shaped steel card respectively.For satisfying the instructions for use of different occasions, connector of the present utility model can be different form of structure, and this connector can be the fixed block that connects firmly with girder that is positioned at the girder two ends, also can be the back timber that connects firmly by securing member and girder.This radial type floor stringer and existing down-hole metal compressibile support are used, and can greatly improve its bearing capacity, satisfy the needs of big drift section safety support.
Floor stringer described in the utility model and existing metallic support are used, and have improved the supporting capacity and the stability of entire bracket, can satisfy the requirement of large span stope drift active workings safety support, have enlarged the scope of application of existing metal compressibile support.This floor stringer is simple and reasonable for structure, and is easy to process, and cost is low, easy for installation, and applicability is good, can produce tangible economic and social benefit.
Description of drawings:
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is a mount fixing structure schematic diagram of the present utility model;
Fig. 3 is the mount fixing structure schematic diagram of the another kind of structure of the utility model;
In conjunction with the accompanying drawings the utility model is further described as follows: the connector that this big section metal compressibile support radial type floor stringer is connected firmly by the girder 8 with existing metal compressibile support, with the fixing U shaped steel card 1 of the canopy leg 10 of metal compressibile support with constitute with the hinged diagonal brace 2 of connector and U shaped steel card 1 respectively.Connector of the present utility model is the fixed block 11 that connects firmly with girder that is positioned at the girder two ends, and this fixed block can connect firmly by welding and girder.Connector of the present utility model also can be the back timber 7 that connects firmly by securing member and girder.The securing member that is used to connect firmly back timber and girder described in the utility model is made up of U-bolt 6, packing ring 4, pressing plate 5 and nut 3.U shaped steel card 1 of the present utility model is fixing by the canopy leg 10 of wedge-type card cable public under the present coal mine and metal compressibile support.
