Connect steel tube head；Seamless long steel tube head, seamless short steel pipes end and the hinged steel tube head is fixed by nut, nothing
Long steel tube head, seamless short steel pipes end and hinged steel tube head is stitched to be embedded on fixed screw.
Further, screw thread is provided on the threaded body of rod；The screw thread is axially distributed along the body of rod, and institute
Stating screw thread is unidirectional rotation screw thread.
Further, both the seamless long steel pipe, seamless short steel pipes are in vertical distribution；The seamless long steel pipe
Quantity is three；The quantity of the seamless short steel pipes is three；The quantity of the extension steel pipe is 6.
The beneficial effects of the present invention are: the present invention provide it is a kind of facilitate telescopic type arc top beam temporary support device, lead to
It crosses and adds bending hinge mechanism, extends steel pipe, sliding block, band card slot nut, nut apparatus, so that arc top beam during transportation can be with
Retraction volume, convenient transportation can increase supporting area by extending steel pipe in Bracing Process, realize active support, control top
The time required for gib can be greatly decreased in excellent effect, enhance gib supporting effect, convenient and simple, supporting area
Simplicity is adjusted, is transported more convenient.
The present invention compared with prior art, has the advantages that
Common temporary support device control top area is small, the top plate area that the present apparatus can be bigger with supporting, so that supporting effect is excellent
Different, safety coefficient is higher.
It is big for common temporary support device volume, inconvenient problem is transported, the present apparatus, can be with when without supporting
Steel pipe will be extended to withdraw, so that transport is more convenient, accelerate tunnel construction.
For common temporary support device can only passive protecting, supporting effect is poor, and serious peace can be brought to underground work
Full hidden danger, the present apparatus have dual improvement, first point, are formed by the hinged extension steel pipe of bending hinge connector and hinged steel pipe
" class triangle " structure is more stable；Second point, mating sliding block can be slided directly in threaded steel pipe, can actively and
When carry out supporting.Security risk solves, and safety coefficient greatly improves.
