Description
Technical field
The utility model relates to a kind of constructing tunnel equipment.What be particularly related to is a kind of formwork jumbo of placing tunnel invert.
Background technology
After finishing, tunnel excavation must use concrete placing lining cutting and inverted arch.Common way is to adopt lining trolley to come the placing lining cutting, and inverted arch and inverted arch filled section are then by manually building.The shortcoming of manually building inverted arch is that efficient is low, and quality can not get guaranteeing that the excavation operation that also influences the tunnel can not parallelly with the pouring construction of inverted arch carry out, and to other operation operation also serious interference, can not adapt to the construction requirement in the tunnel of growing up.For overcoming this deficiency, Chinese patent ZL03232894.X has proposed a kind of " tunnel full-circular monolithic lining formwork jumbo ", main composition comprises truss open web type Vierendeel girder, be installed in vehicle frame on the Vierendeel girder by the guide wheel guide rail structure, the Vierendeel girder bottom is equipped with liftable front and back base, top is equipped with the anti-floating platform, is installed in various template oil cylinders and the corresponding different templates that is connected on each oil cylinder on the vehicle frame.The formwork erection and the demoulding are all finished by the template oil cylinder.The whole lining cutting operation of loopful that utilizes alternately migrating of vehicle frame and Vierendeel girder to finish tunnel cross-section.The working method of this chassis is the migration mode that replaces, and structure is comparatively complicated, and manufacturing cost is higher; During concrete curing, the vibrations when muck haulage vehicle and pedestrian etc. pass through in the open web type bogie frame can pass to invert form and influence the concrete placing quality of not solidifying fully.
The utility model content
The purpose of this utility model provides a kind of inverted arch pouring quality, simple in structure and inverted arch pouring quality of guaranteeing and was not subjected to the tunnel overhead arch mould plate trolley with floating type traffic under carriage of car vibration influence.
Realize the tunnel overhead arch mould plate trolley with floating type traffic under carriage of the utility model purpose, its formation comprises anti-floating platform, preceding travelling wheel, back travelling wheel, ascending/decending back and front supporting seat, contain the open web type bogie frame of column, traffic under carriage and be arranged on the invert form of traffic under carriage below, described back and front supporting seat and forward and backward travelling wheel are installed in the two ends of traffic under carriage, the anti-floating platform is installed in the top of bogie frame, described travelling wheel is the ascending/decending travelling wheel, and described traffic under carriage is installed in the top of invert form with a relocation mechanism.
Operating principle of the present utility model is as follows:
Trolley running puts down the ascending/decending back and front supporting behind inverted arch placing station, by back and front supporting bogie frame is lifted in the lump together with travelling wheel and invert form and put invert form and put in place, makes anti-floating support jacking then and puts in place fixingly, can carry out the inverted arch placing.During placing and concrete curing, muck haulage vehicle and pedestrian etc. can pass through from the open web type bogie frame.Owing between traffic under carriage and invert form, be provided with a relocation mechanism, traffic under carriage floats with respect to invert form, the vibrations that cause on traffic under carriage when vehicle and walk then only make traffic under carriage unsteady and can not pass to invert form with respect to invert form, thereby realize that inverted arch placing quality was not subjected to the purpose of car vibration influence.After the inverted arch concrete reaches form removal intensity, fall anti-floating earlier and support, again bogie frame is upwards lifted in the lump together with invert form by the ascending/decending back and front supporting then, realize the demoulding.After finishing the demoulding, put down forward and backward ascending/decending travelling wheel, pack up the back and front supporting seat again, whole chassis is changed by forward and backward travelling wheel support.With drive unit chassis is slowly moved forward then, walking arrives next inverted arch placing station.Drive unit can be continued to use prior art and be arranged on the chassis, also can establish in addition separately, for example establishes the migration that a hoist engine also can be finished vehicle frame in the tunnel in addition.
Described ascending/decending supporting seat can be selected the hydraulic elevation type supporting seat that has up-down adjustment oil cylinder and lateral adjustments oil cylinder for use.Regulate the position of bogie frame by the position of regulating the back and front supporting seat, thereby guarantee to be installed in accurately putting in place of invert form under the bogie frame.
Described ascending/decending back and front supporting seat also can be a jack type.When adopting the supporting seat of jack type, should notice that synchronization action is to keep the balance of bogie frame.
For guaranteeing the run trace of chassis, described preceding travelling wheel can adopt guide tracked running roller.Before mobile trolley used, install track earlier, then ride after running roller puts down and be stuck on the track, guarantee accurately moving into place of chassis by track.
Still can one extension be set in the underframe rear end of bogie frame, affixed filling template below this extension when carrying out next section inverted arch placing operation, is finished the mechanization of the filled section on the preceding paragraph inverted arch and is built operation.
Considering to need to lay this situation of reinforcing bar before the inverted arch placing, for guaranteeing the smooth reach of chassis, can one extension be set at the underframe front end of described bogie frame, and preceding travelling wheel is installed in the front end of this extension.Utilize this extension to cross over next inverted arch placing station of laying reinforcing bar, travelling wheel is walked on the bottom surface, tunnel before next station before making.
Compared with the aforementioned existing similar products, the utility model has the advantages that and reduced Vierendeel girder that structure is more simple, greatly reduces manufacturing cost; Change original alternately migration for the one way migration, account for working space less; Safe and reliable, operating maintenance is convenient, and applicability is strong; Have and carry out large cross-section tunnel inverted arch monolithic concrete mechanization mould and build up the technical advantage that shape and inverted arch, filling separate placing, can fully guarantee the placing quality of tunnel invert.The time do not influence slag tap the carrying out of transportation or other operation of driving carrying out inverted arch placing construction, and the placing quality is not subjected to the car vibration influence, improved the whole work efficiency of constructing tunnel greatly, helped the reduction of erection time, saved cost.The placing construction of inverted arch of railway tunnel is specially adapted to grow up.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related in the present embodiment.
