Time, use the Mechanical Moving such as excavator or loader, during operation, extremely inconvenient and time-consuming, laborious.For ensureing that tunnel inverted arch is even
More continuous construction, need to organize inverted arch trestle, therefore, need to develop one and can automatically walk, and crosses over inverted arch excavation area, pouring area simultaneously
And Deng Ge region, maintenance district, the inverted arch trestle stand pushed ahead with tunnel inverted arch excavation construction is the most necessary and urgent.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of propelled tunnel inverted arch trestle, it is to avoid existing tunnel
During construction, the split of trestle beam is arranged, and need to coordinate with tunnel excavation, continuous movable trestle beam, it has not been convenient to the problems such as construction.
Propelled tunnel inverted arch trestle of the present utility model, including trestle, travelling wheel and a spike；Described trestle includes stack
Bridge, truss frame for connecting and trestle driving means, trestle beam is that two and Parallel Symmetric are arranged, trestle beam include front trestle beam,
Middle trestle beam and rear trestle beam, front trestle beam, rear trestle beam be inserted through with middle trestle joist support set be connected, front trestle beam and rear trestle beam
Bottom surface is equipped with tooth bar, and described driving means includes two motor being fixed on middle trestle beam two ends, the output shaft of motor
On be fixed with gear and by gear with corresponding before trestle beam or the rack gear connection of rear trestle soffit；Described travelling wheel
It is located at front trestle beam front end, middle trestle beam front end and rear end and rear trestle beam rear end；Prop up spike to arrange with travelling wheel one_to_one corresponding.
Further, a length of 20m to the 50m of described trestle.
Further, described truss frame for connecting is fixedly connected between two middle trestle beams.
Further, described stack Bridge Sections is rectangular tubular section.
Further, trestle beam and inverted arch template with the use of, inverted arch pattern board supporting is on middle trestle beam.
The beneficial effects of the utility model are: this device simple structure, easy to use, during constructing tunnel, for convenience of trestle
Upper traveling vehicle, and avoid delaying work, use trestle beam split when present arrangement avoids existing tunnel construction to arrange, need to open with tunnel
Dig cooperation, continuous movable trestle beam, it has not been convenient to the problems such as construction, it is achieved the whole self-propelled movement of trestle.
Accompanying drawing explanation
