Abstract
The utility model relates to a double guiding-beams bridge-laying machine for highways and railways, comprising a main guiding-beam and an auxiliary guiding-beam butt-jointed at the front end, and the front part of the auxiliary guiding-beam is provided with a supporting leg. A front and a rear cranes are arranged on the main guiding-beam; the underside of the main guiding-beam is provided with a front and a rear supporting legs, an edge beam oil cylinder and a front and a rear trolleys connected with the main guiding-beam through a hanging wheel and a supporting roller; the trolley body of the front trolley is provided with an upper and a lower joists connected by a central shaft and are provided with rolling bodies. Compared with the existing double guiding-beam bridge-laying machines, the utility model has the advantages of light weight and short machine body, a vertically moving rail does not need to be laid, and the utility model is suitable for the construction of a bridge with a small curvature radius.
Description
The utility model relates to the bridge erection machinery of highway and railway, specifically a kind of double guide beam bridge erecting machine.
At present, the double guide beam bridge erecting machine that in highway and railway bridge erecting operation, uses, mainly by the leading beam of trussed construction and configuration in the above can be longitudinal and transverse mobile play crane and be fixed on below the leading beam vertically move chassis and before, during and after supporting leg forms,, assembly unit speed simple in structure with it is widely used soon.But, its advancing in operation process moves ahead because of relying on vertical shift chassis integral body, need on the good precast bridge of frame, lay long rails, and the length of nose girder can not be less than 2.5 times of pier distance, operational difficulty when setting up curved bridge in addition, the curved bridge construction of inapplicable small curvature radius.
The purpose of this utility model is the problems referred to above at existing double guide beam bridge erecting machine existence, and provides a kind of length that does not need to lay advance track, nose girder at bridge floor can foreshorten to 1.75 times of pier distance and be suitable for setting up the novel double guide beam bridge erecting machine that small curvature radius is bent bridge.
The technical scheme that realizes above-mentioned purpose is: a kind of double guide beam bridge erecting machine, have leading beam and butt up against front end and the guidance beam of telescopic legs forwardly is set, on leading beam, dispose forward and backward crane, below leading beam, be provided with forward and backward telescopic legs and reach the forward and backward chassis that is connected with leading beam by change gear and carrying roller with the side bar oil cylinder.
The technical scheme that realizes above-mentioned purpose also comprises: the upper and lower joist that the car body of preceding chassis is provided with relative configuration and is connected by central axis, its fitting face of the both sides of upper and lower joist is provided with corresponding deep-slotted chip breaker, is equipped with rolling element in its deep-slotted chip breaker.
The utility model is compared with existing double guide beam bridge erecting machine, has following advantage:
1, do not need on the good precast bridge of frame, to lay long rails;
2, exchange length foreshortens to 1.75 times of pier distances by 2.5 times of original piers distances;
3, can realize the complete machine gyration, be suitable for setting up of curved bridge;
4, complete machine is in light weight.
Accompanying drawing 2 is that back chassis and leading beam have reached crane configuration structure schematic diagram;
The utility model is described in further detail below in conjunction with drawings and Examples:
Provide as accompanying drawing 1, this double guide beam bridge erecting machine has the leading beam 1 of trussed construction and is docked at the guidance beam 2 of its front end, and its leading beam is the load spandrel girder, and teaching beam is simple and easy lightweight structures.Be respectively arranged with telescopic legs 5,6,7 at the two ends of leading beam and the front portion of guidance beam.On leading beam 1, dispose forward and backward crane 3,4, be respectively arranged with side bar oil cylinder 8 and forward and backward chassis 9,10 in the bottom of leading beam 1.
Provide as accompanying drawing 2, accompanying drawing 3, the top and bottom of the leading beam 1 of this double guide beam bridge erecting machine are respectively arranged with track.Planer-type plays the road wheel of crane 3,4 by the bottom and cooperates with the track of its upper end and has realized vertically moving of crane, is provided with the horizontal travelling car that disposes on cross track and this track by self crossbeam and finishes horizontal mobile to hanging precast beam and play crane.Two forward and backward chassis 9 and 10 are assemblied on the track of leading beam lower end by two groups of change gears 11 and the carrying roller 12 that disposes motor separately respectively, are used to realize that leading beam vertically moves or make two chassis to vertically move with guidance Liang Shangzuo at leading beam on two chassis.Dispose the lateral rows travelling wheel in the lower end of each chassis, its be laid on the cross track of construction on the beam and cooperate and can realize that complete machine is laterally mobile.
Provide as accompanying drawing 3, the car body of the preceding chassis 9 of this bridge formation machine is provided with relative configuration and by the upper and lower joist 14 and 15 that central axis 13 is connected, is used for realizing leading beam corner at erection process.The arc groove of edge rolling element 16 on its fitting face of the both sides of upper and lower joist, offering, the friction when being used to reduce upper and lower joist and reversing relatively.
This double guide beam bridge erecting machine is when building bridge construction, stretch out rear support leg make the back chassis unsettled after, start back chassis change gear motor and the back chassis can be moved forward to the appropriate location on leading beam, fix the back chassis and reclaim rear support leg, before can starting, the carrying roller motor of back chassis and the leading relative chassis of beam is moved forward, and pier was finished the supporting of nose girder and fixing before the supporting leg of teaching the beam front end was arrived, pier and fall rear support leg and make back chassis reach in place before chassis makes it to move to before then starting respectively, promptly by step type move finish bridge formation machine complete machine stride the pier displacement.In the curved bridge erection process, when after after chassis moves forward to the appropriate location, can start the traversing motor of back chassis, make complete machine rotate respective angles around the upper and lower joist central axis of preceding chassis, can realize turning to of the machine of building bridge, finish setting up of curved bridge.The supporting leg of its leading beam front portion can be used for the bridge formation machine turn to finish after, the supporting when the upper and lower joist of preceding chassis resets.
