Abstract

The utility model provides a folding individual stanchion which is applied to temporary supporting of mine roadways. The folding individual stanchion comprises an individual stanchion, and a movable column arranged in the individual stanchion, wherein the top of the individual stanchion is provided with a folding top beam frame which comprises two symmetrically arranged protective top beams, two supporting beams, two straight pulling rods and position-limiting rings; the two protective top beams are hinged with each other by pin shafts of the protective top beams; one ends of the two supporting beam are respectively hinged on the bottom surfaces of the two protective top beams and the other ends of the two supporting beams are hinged on the top of the individual stanchion; one ends of the two straight pulling rod are hinged on the two supporting beams and the other ends of the two straight pulling rod are hinged on the position-limiting rings that are sheathed on the movable column. The temporary stanchion can be assembled conveniently, has simple operation procedure, short supporting time and quick speed, is applicable to various roadways, and has obvious advantages when being used in the broken top plate roadways emergently needing to be supported. The stanchion and the top beam are integrated into a whole and can be disassembled more simply, a certain fitting does not need to be disassembled, and furthermore, the equipment can be piled easily, taken away conveniently and managed conveniently.

Description

Folding single prop

Technical field

The utility model relates to a kind of folding single prop, is particularly useful for the temporary lining of mine laneway.

Background technology

The driving face in tunnel generally uses the prop roof supporting, avoids its distortion or collapse suddenly and emit of sinking.Coal-face to the 30～40m scope of the place ahead because drastic deformation often takes place in the tunnel that influences of supported pressure, also need to set up prop.The employed prop of mine generally is a hydraulic prop at present, only had by geological conditions and adaptive restriction and uses wood to put the prop of other types such as post or advance timbering under a small amount of situation.Existing hydraulic prop must be equipped with the supporting that metal hinge top beam just can be used for top board, and the overlap joint process is loaded down with trivial details, and the operating time is longer, is not suitable for using under relatively poor in lithology, as the to be badly in need of supporting condition.

Summary of the invention

The purpose of this utility model is the weak point that overcomes in the prior art, and a kind of simple in structure, collapsible, the supporting time spent is short, speed is fast, easy for installation folding single prop is provided.

For achieving the above object, folding single prop of the present utility model, comprise individual prop, be located at the post alive in the individual prop, be provided with a folding back timber frame at the top of described individual prop, the back timber frame comprises that symmetrically arranged two are protected back timber, two brace summers, two Drag links and spacing ring, two to protect back timber hinged through protecting the back timber bearing pin, one end of two brace summers is hinged on two respectively and protects the back timber bottom surface, the other end is hinged on the top of individual prop together, two Drag link one ends are hinged on respectively on two brace summers, and the other end is hinged on respectively on the spacing ring that is set on the post alive; Described brace summer length is no more than protects 1/2 of back timber length.

Beneficial effect: connect a folding back timber structure on common hydraulic prop top, when the post of living rose, the deployable scar that is adjacent to of pillar back timber applied support force, and when the post of living descended, back timber shrinks with individual prop became a umbrella pillar integral body.Equipment is easy for installation, and operation is simple, and 1～2 people can finish temporary lining work; Single folding single prop can be realized the supporting to top board, and the supporting time spent is short, speed is fast, is adapted to various tunnels, uses to have clear superiority in the breaking roof tunnel of being badly in need of supporting; Pillar and back timber unite two into one, and unload more simple and easyly, and directly tapping gets final product, and does not need certain accessory is dismantled; Equipment is stacked easily, is convenient to resettlement, convenient management.Folding single prop is realized the integrated, easy for installation, simple to operate of pillar and back timber, and single pillar can be realized the support to top board, and is suitable to the temporary lining under all kinds of top board conditions.

Among the figure: 1-protects back timber, the 2-brace summer with protect the back timber bearing pin, 3-protects the back timber bearing pin, the 4-brace summer, 5-brace summer and individual prop bearing pin, the bearing pin of 6-Drag link and brace summer, 7-Drag link, 8-Drag link and spacing ring bearing pin, the 9-spacing ring, 10-post alive, 11-individual prop.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Folding single prop of the present utility model mainly is made up of hydraulic prop and the collapsible back timber frame established thereon, and whole collapsible back timber frame is hinged on the hydraulic prop top, with hydraulic prop by constituting one.Hydraulic prop comprises individual prop 11, is located at the post alive 10 in the individual prop 11.Collapsible back timber frame by two protect back timber 1 through protecting back timber bearing pin 3 hinged constitute protect roof construction, two brace summers 4 are through the braced structures of brace summer and individual prop bearing pin 5 hinged formations, two Drag links 7 constitute the adjustment structures through spacing rings 9.Protect back timber 1 and brace summer 4 via brace summer with to protect back timber bearing pin 2 hinged, Drag link 7 is hinged via the bearing pin 6 of Drag link and brace summer with brace summer 4.The back timber frame comprises that symmetrically arranged two are protected back timber 1, two brace summers 4, two Drag links 7 and spacing rings 9, two to protect back timber 1 hinged through protecting back timber bearing pin 3, one end of two brace summers 4 is hinged on two respectively and protects back timber 1 bottom surface, the other end is hinged on the top of individual prop 11 together, two Drag link 7 one ends are hinged on respectively on two brace summers 4, the other end is hinged on respectively on the spacing ring 9 that is set on the post 10 alive, and brace summer 4 length are no more than protects 1/2 of back timber 1 length.

Implementation process: the folding single prop (shown in Figure 1) of contraction state vertically is placed on the place that needs supporting, to individual prop 11 fluid injections, after the post alive 10 of pillar rises, brace summer 4 drives collapsible back timber structure and launches (shown in Figure 2), 7 pairs of back timber structures of Drag link are transferred tiltedly simultaneously, the post 10 of living continues to rise, and launches fully to be adjacent to back and to apply certain support force until protecting back timber 1, stops fluid injection.After support work finished, to individual prop 11 tapping, the post 10 of living descended, and collapsible back timber structure is shunk immediately, and whole process does not need the back timber structure is dismantled and installed.The length of protecting back timber 1 can be processed into 500～800mm and not wait, and the length of brace summer 4 is no more than protects 1/2 of back timber 1 length, requires the stroke of the post alive 10 of individual prop must not be lower than the difference in height that collapsible back timber structure folds front and back.
