Abstract
The utility model discloses a longitudinal and transverse movement conversion mechanism of a bridge girder erection machine, comprising a conversion hinged support. A rotating mandrel is rotatingly disposed at the lower part of a middle and a rear rack crossbeams. The lower end of the rotating mandrel is in a rotating installation with the conversion hinged support. The conversion hinged support bottom is hinged to a big vehicle walking mechanism through a pin. The bottom rolling wheel of the big vehicle walking mechanism is capable of lateral moving along a prefabricated beam. The utility model is advantageous in that the transferring and stationing of the bridge girder erection machine between two or over two short-distance bridges under the limitation of landform, and the retreating of the bridge girder erection machine at an erected bridge floor can be conducted.
Description
Technical field
The utility model relates to mechanical fields such as public affairs, railway bridge erecting machine, especially highway, railway bridge erecting machine set up between adjacent two and above bridge prefabrication beam bridge shift, short distance transition and bridge type construction finish after the bridge formation machine at aspects such as bridge floor retreat (restriction of the place ahead landform), a large amount of expenses such as repeatedly dismounting, assembly unit, transportation have been reduced, and significantly shortened different bridge erection construction periods therebetween, have economic benefit widely.
Background technology
China region is wide, with a varied topography, and many mountain areas, gully, especially in ground speedway, railway constructions such as mountain area, hills, and two and above bridge close together, great amount of manpower and material resources has been wasted in dismounting, assembly unit repeatedly, and lifting cost is with higher; Limited by the place during regions with complex terrain bridge erection, can not carry out assembled on site, so need in that suitably assembling back in place is whole in place, integral hoisting needs large tonnage crane, and manpower, correlative charges consumption are bigger, and limited by the place.Shift between, bridge in place for ease of above situation, longitudinal and transverse transfer converting mechanism is set after, lay interim orbit and can realize easily.
The utility model content
The purpose of this utility model provide the bridge formation machine in length and breadth, the transfer converting mechanism, finish the bridge formation machine easily in the transfer, in place that is subjected between landform restriction, two and two above short distance bridges, setting up functions such as bridge floor retreats.
In order to achieve the above object, the technical scheme that the utility model adopted is:
The bridge formation machine is transferred converting mechanism in length and breadth, include the conversion free bearing, be rotatablely equipped with mandrel in bottom preceding, the medium-height trestle crossbeam, the lower end of mandrel is rotated with the conversion free bearing and is installed, conversion free bearing bottom is by the articulated cart walking mechanism of bearing pin, and the bottom roller of cart walking mechanism can laterally move along precast beam.
Described mandrel top is connected with crossbeam, the bottom is connected with big vehicle frame, converts back fastening bolt locking.
In the bridge formation machine, the longitudinal and transverse transfer converting mechanism of after-poppet, include the conversion free bearing, in, the bottom and the chassis junction of after-poppet crossbeam be equipped with mandrel, install with the conversion free bearing lower end of mandrel, conversion free bearing bottom is by flange, the articulated big mechanism of car of bearing pin, and the bottom line travelling wheel of big mechanism of car can move along the vertical, horizontal track of laying in advance.
The bridge formation machine is vertical, traversing switching mechanism turn to free bearing with in, after-poppet crossbeam flanged plate connects, employing apotting spindle location, be that the bottom cart laterally moves when the bridge machine is normally set a roof beam in place operation, when between the needs bridge, shift, transition, when retreating, the tail supporting leg, the medium-height trestle elevating mechanism, 3 jackings respectively of interim supporting leg, make medium-height trestle bottom cart, after-poppet bottom traveling mechanism of the larger traveller unsettled respectively (must not be simultaneously unsettled), by artificial half-twist and location, locking, laying vertically moves track in the road wheel bottom, 3 elevating mechanisms land respectively, road wheel is fallen within on the track, the locking connecting bolt; When determining that big mechanism of car traffic direction is consistent, could start, realize the above-mentioned function that vertically moves.
The utility model is normally to set a roof beam in place on the basis of operation function satisfying the bridge formation machine, the longitudinal and transverse transfer converting mechanism of increase, satisfied between transition, bridge shift, bridge floor retreats requirement, and is easy and simple to handle, remarkable benefit.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the free bearing structure chart that turns to of the present utility model.
Fig. 3 is a complete machine schematic diagram of the present utility model.
The specific embodiment
As Fig. 1, shown in Figure 2, the bridge formation machine is transferred converting mechanism in length and breadth, in including, after-poppet crossbeam 1, turn to free bearing 2 by flanged plate and mandrel 3 with in, after-poppet crossbeam 1 connects, be inserted with apotting spindle 6 on the sidewall of mandrel, during apotting spindle 6 is incited somebody to action, the after-poppet crossbeam is spacing, turn to free bearing 2 hinged by bearing pin 4 and bottom cart walking mechanism 5, vertical, bridge formation tail supporting leg during traversing conversion, medium-height trestle temporary up-down mechanism, interim supporting leg all is in the jacking state, bottom cart walking mechanism 5 is de-orbited, dismounting turn to free bearing 2 with in, the locknut at after-poppet crossbeam 1 place's attachment bolt and mandrel 3 places, turn to free bearing 2 and 5 while of bottom cart walking mechanism half-twist, lock bolt, mandrel 3 place's locknuts, and at direction of motion laying temporary track, landing tail supporting leg medium-height trestle elevating mechanism, interim supporting leg makes the road wheel of bottom cart walking mechanism 5 fall within the temporary track top, and stressed, finish vertical, the transverse-moving mechanism conversion process.
When complete machine was normally set a roof beam in place, switching mechanism was in traversing state, satisfied bridge machine laterally moving in the fabric width direction; Be the state of vertically moving during operating modes such as transfer between bridge, transition, bridge floor retreat, finish vertically moving of complete machine.
By this novel practical of above summary on the basis of satisfying the horizontal locomotive function of state of setting a roof beam in place, can also satisfy vertically moving of bridge formation machine, and this mechanism is a kind of novel traveling mechanism reliable, easy and simple to handle not increasing manufacturing cost on the basis originally.
