Abstract
The utility model discloses a tunnel reversed arch work bridge including that: a front bridge is connected with a back bridge through a gemel; the front bridge and the back bridge are both provided with tracks for vehicles with tracks and roadways for vehicles without tracks; the lower part of the front bridge is provided with a hydraulic support, a rolling device and an operation controlling device; the back bridge is provided with a moving device beneath; the two ends of the front bridge and the back bridge are respectively provided with crown blocks for steel wires of the roiling device; and the steel wires are provided with hooks. The utility model has the advantages of suitability of different reversed arch work height, small size, good stability, convenient moving and reposition as well as suitability for vehicles with or without tracks.
Description
The utility model relates to a kind of tunnel invert operation bridge that is used for construction of tunnel such as railway, highway, water conservancy, belongs to the construction of tunnel field of mechanical technique.
At present, tunnel invert operation bridge of the prior art generally all can only pass through railroad vehicle, because in the inverted arch work progress, the inverted arch forming face is big with the discrepancy in elevation of excavation face, and be subjected to the railroad vehicle restriction of the gradient voluntarily, the slope length of its inverted arch operation bridge is very long, therefore, shortcomings such as that existing operation bridge exists is bulky, inefficiency, equipment moves in place and operation inconvenience, occupied ground is big, and existing inverted arch operation bridge can not be applicable to simultaneously by rail and trackless vehicle, so its compliance is relatively poor.
The purpose of this utility model is: provide a kind of and can adapt to that the different inverted arch operation discrepancy in elevation, volume are little, good stability, move convenience in place and can be applicable to the tunnel invert operation bridge that trackless and railroad vehicle pass through simultaneously.
The utility model is to constitute like this: it comprises propons (1), back axle (2) and operating control device (8), propons (1) is connected by hinge (3) with back axle (2), on propons (1) and back axle (2), be equipped with track (4) that can pass through for railroad vehicle and the track (5) that can supply trackless vehicle to pass through, hydraulic pressure is housed in propons (1) bottom supports (6) and hoist engine (7) and operating control device (8), walking mechanism (9) is housed under back axle (2), the fixed pulley (10) that supports hoist engine wire rope (13) all is housed respectively at the two ends of propons (1) and back axle (2), and hook (14) is housed on wire rope (13); On propons (1) and back axle (2), lift oil tank (11) is housed also all; The hydraulic jack (12) that can regulate walking mechanism (9) lifting also can be housed between walking mechanism (9) and back axle (2); It is the vertical curve structure that propons (1) and back axle (2) are gone up the track of laying (4).
Owing to adopted technique scheme, on the utility model, be provided with track (4) and wheel road (5), therefore the utlity model has the advantage of the haulage vehicle use that can be suitable for trackless wheel and rail wheel; In addition, can promote the rail haulage vehicle on the utility model, shorten the length of back axle greatly because hoist engine has been installed, alleviated dead load, and full-bridge is only established place's hinge, can make structure be firm knot state when full-bridge moves, and has increased the rigidity and the stability of the body of a bridge.

Embodiment of the present utility model: hydraulic pressure of the present utility model supports (6), hoist engine (7), operating control device (8), walking mechanism (9), fixed pulley (10), lift oil tank (11) hydraulic jack (12) all adopts the complete finished product of selling on the market to assemble, hoist engine (7) preferably adopts hydraulically driven winch, propons (1) is connected by hinge (3) with back axle (2), hinge (3) preferably adopts the single face hinge, propons (1) and back axle (2) can adopt welding fabrication, and welding is got on the right track (4) and track (5) on propons (1) and back axle (2), load onto hydraulic pressure in propons (1) bottom and support (6) and hoist engine (7) and operating control device (8), under back axle (2), load onto walking mechanism (9), fixed pulley (10) is all installed at two ends at propons (1) and back axle (2) respectively, wire rope (13) is had mercy on fixed pulley (10), and the fag end of wire rope (13) is linked to each other with fag end linkage hook (14) with pin with rope clamp chucking back; For the purpose of in use firm more, can on propons (1) and back axle (2), install lift oil tank (11) again; For easy to adjust, can between walking mechanism (9) and back axle (2), install the hydraulic jack (12) that to regulate walking mechanism (9) lifting; Adopt the vertical curve structure to get final product on propons (1) and the last track of laying (4) of back axle (2).
When using the utility model, the operation bridge is moved to the inverted arch construction section, adjust two ends after the contraposition and connect short rail, making two ends connect short rail reliably is connected with the job site conveying track, opening hydraulic pressure supports, can carry out the inverted arch construction after the locking, other construction machinery can pass through on the operation bridge simultaneously, after the operation bridge and the conveying track transition slope section gradient strengthen, in heavily loaded rail Transport Machinery during by the operation bridge, for overcoming the frictional force deficiency between the hauling capacity of a locomotive and wheel and the track, adopt the hoist engine traction, trackless transportation and working truck can be smoothly by becoming the slope section.When the construction of job step inverted arch finishes, take two ends apart and connect short rail, withdrawal hydraulic pressure supports, make road wheel to stressed, under action of gravity, propons and back axle and single face hinge form rigid structures naturally, place mat slide plate below the operation bridge of inverted arch section of having constructed, slide plate and walking mechanism hold up the operation bridge jointly, and the operation bridge can utilize hoist engine to move from carry by establishing earth anchor, also can adopt locomotive tractions such as electric locomotive to move in place.
