Description
Technical field
The utility model is related to a kind of support frame, and in particular to working support in a kind of tunnel.
Background technology
During constructing tunnel, because tunnel-side is arc, common scaffold is difficult to install and used, especially tunnel top
When portion constructs, the working scaffold in tunnel both sides is often due to insufficient height can not be continuing with, it is necessary to change higher apply
Work support, the more ring that do not stop of construction bracket causes workman's amount of labour big, and construction speed is slow.
Utility model content
The technical problems to be solved in the utility model is that ceaselessly more ring causes workman's amount of labour to conventional tunnel construction bracket
Greatly, there is provided a kind of adjustable for height construction support for tunnel slowly for construction speed.
In order to solve the above technical problems, the utility model uses following technical proposals：A kind of construction support, including left branch
Frame, right support, supporting plate and stay hook, left socle and right support are articulated and connected by rotating shaft, supporting plate be arranged on left socle and
The top of right support, is provided with expansion link between left socle and right support；The left socle is included above brace and support bar, brace
It is connected with support bar provided with support guardrail, brace centre is provided with limited block, and left socle and right support are symmetrical arranged；The stay hook
One end is fixed on the brace of right support by chain, and the stay hook other end is flexibly connected with the brace of left socle, stay hook two
End is arranged at the top of brace limited block.
The stay hook has three.
The supporting plate includes intermediate plate, and intermediate plate both sides are sequentially provided with the first side plate, the second side plate, intermediate plate, first
It is articulated and connected between side plate and the second side plate.
The support guardrail includes some cross bars and montant, and cross bar one end is connected with montant, the other end and support bar connect
Connect, the cross bar of support guardrail both sides is provided with side wall wheel.
The brace bottom is provided with slipmat.
Scissor-shaped is made using the utility model of said structure, adjusting bracket height, one section of tunnel are needed according to construction
Internal one support of construction can be completed, it is to avoid change support, reduce workman's amount of labour, quick construction safety.

When Fig. 3 is that the utility model is in deep low gear position, left socle and right support top structure schematic diagram；
When Fig. 4 is that the utility model is in highest file location, left socle and right support top structure schematic diagram.
Embodiment
As shown in Figures 1 to 4, the utility model includes left socle 1, right support 2, supporting plate 3 and stay hook 7, left socle 1
It is articulated and connected with right support 2 by rotating shaft 4, supporting plate 3 is arranged on the top of left socle 1 and right support 2, left socle 1 and right branch
Expansion link 8 is provided between frame 2；The left socle 1 includes brace 11 and support bar 12, and the top of brace 11 is connected with support bar 12
Have and be provided with limited block 13 in the middle of support guardrail 5, brace 11, left socle 1 and right support 2 are symmetrical arranged；Described one end of stay hook 7 leads to
Cross chain 71 to be fixed on the brace 11 of right support 2, the other end of stay hook 7 is flexibly connected with the brace 11 of left socle 1, stay hook
7 two ends are arranged at the top of the limited block 13 of brace 11.The setting of limited block 13 effectively prevents stay hook from gliding.
The stay hook 7 has three.The supporting plate 3 includes intermediate plate 31, and the both sides of intermediate plate 31 are sequentially provided with the first side
Plate 32, the second side plate 33, are articulated and connected between intermediate plate 31, the first side plate 32 and the second side plate 33.Three are connected with stay hook 7
The length of chain 71 it is different；The third gear regulation of support is corresponded to respectively, selects the stay hook 7 of different length chain, it is possible to achieve branch
The regulation of frame different height, plays to left socle and right support after chain expansion and draws fixed effect over to one's side, prevent left socle and the right side
Support is folded down, and causes security incident；Chain is shorter, and propping for support is highly higher, with the rise of support, is used on support
It is less and less in the working face of laying supporting plate 3.When support is in deep low gear position, for laying the working face of supporting plate 3 most
Greatly, all expansion layings of supporting plate 3；When support is in middle gear, working face reduces for the first time, at this moment, is in the outermost of supporting plate 3
Second side plate 33 of side is folded down；When support is in highest file location, second of reduction of working face, the first side plate 32 is rolled over downwards
It is folded.
It is described support guardrail 5 include some cross bars 51 and montant 52, the one end of cross bar 51 is connected with montant 52, the other end and
Support bar 12 is connected, and the cross bar 51 of support guardrail 5 both sides is provided with side wall wheel 6.
The bottom of brace 11 is provided with slipmat 14.
