Abstract
The utility model discloses a caterpillar type bridging machine for roads and railways, comprising a main beam, a lifting trolley, a front supporting leg, a middle supporting leg, a rear supporting frame and a rear supporting leg, wherein the lifting trolley is arranged on the main beam; the front supporting leg, the middle supporting leg, the rear supporting frame and the rear supporting leg are arranged on a lower beam of the main beam; the main beam has a box type truss structure; and the bottom ends of the front supporting leg and the middle supporting leg are respectively provided with a rail guide wheel. The caterpillar type bridging machine has the advantages that not only are the stability and the wind-resistant capability of the main beam improved, but also the self weight of the main beam is reduced, the front supporting leg, the middle supporting leg and the rear supporting leg are respectively connected with the lower beam of the main beam by pin shafts and flanges, so that the transportation and site installation are convenient; and simultaneously, in the caterpillar type bridging machine, a special track does not need to be paved for passing holes, weighted hole passing is adopted when a 40-meter beam for roads is erected, self-balanced hole passing is adopted when a 32.5-meter beam for roads and railways is erected, edge beams can be erected in place by one time, so that the safety and reliability are achieved.
Description
Technical field
The utility model relates to steel work precast beam lifting stringer, especially relates to walking public affairs, the dual-purpose bridge formation machine of railway.
Background technology
Most of case structure or the truss structure of adopting of the girder of present domestic public affairs, the dual-purpose bridge formation machine of iron, the girder quality of case structure is heavier, and wind resistance is relatively poor, transports, assembles comparatively inconvenience simultaneously; And truss structure girder stability is bad, and it is lower to make intensity.
Summary of the invention
The utility model purpose is to provide a kind of dual-purpose bridge formation machine of walking public affairs, railway of taking into account practicality, economy.
For achieving the above object, the utility model can be taked following technical proposals:
Walking public affairs described in the utility model, the dual-purpose bridge formation machine of railway, it comprises girder, is arranged on the described girder lifting truck on the beam orbit and is arranged on the front leg strut on the girder underbeam, middle supporting leg, tail-bracket, rear support leg; Described girder is box trussed construction; Be respectively arranged with the rail guide wheel in the bottom of described front leg strut, middle supporting leg.
Described front leg strut, middle supporting leg, rear support leg are connected with the underbeam of described girder with flange by bearing pin respectively.
The utility model advantage is that described girder is set to box trussed construction, has therefore both improved the stability and the wind loading rating of girder, has reduced the girder own wt again; Described front leg strut, middle supporting leg, rear support leg are connected with the underbeam of described girder with flange by bearing pin respectively, have made things convenient for transportation and on-the-spot the installation; Simultaneously, the utility model via hole need not be laid dedicated track, counterweight via hole when setting up 40 meters highway beams, but self-balancing via hole when 32.5 meters highways of frame, railway dual-purpose beam, but set up the side bar one-time-reach-place, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, walking public affairs described in the utility model, the dual-purpose bridge formation machine of railway, it comprises girder 1, is arranged on the lifting truck 2 on the beam orbit on the described girder 1 and is arranged on front leg strut 3, middle supporting leg 4, tail-bracket 5, rear support leg 6 on girder 1 underbeam; Described girder 1 is box trussed construction; Bottom at described front leg strut 3, middle supporting leg 4 is respectively arranged with the rail guide wheel; Described front leg strut 3, middle supporting leg 4, rear support leg 6 are connected with the underbeam of flange with described girder 1 by bearing pin respectively.
