Description
Technical field
The utility model relates to railway machinery apparatus field, particularly a kind of pair of girder gate-type Bridge Erector running gear.
Background technology
At present, when the Bridge Erector using in engineering is worked out of doors, because geographical environment is limited, insufficient space, cannot walk, and need to dismantle parts; Moreover, on more bridge span erecting machine, adopting the motion of driven by motor reductor, impact force is large, and while especially starting, rocking property is large, unstable, and security incident easily occurs.
Therefore, the utility model is to develop on the basis that mainly solves more than currently available technology existence deficiency.
Summary of the invention
The object of utility model is to solve above technical problem, proposes especially a kind of convenience, strong, safe two girder gate-type Bridge Erector running gears of stability of walking.
Based on above-mentioned purpose, the technical problem that the utility model solves realizes by the following technical solutions:
A kind of pair of girder gate-type Bridge Erector running gear, comprise that below, girder two ends is provided with front leg strut and rear support leg, in the middle of girder, be provided with middle supporting leg, on described front leg strut and rear support leg, be respectively equipped with jack up unit, hydraulic cylinder is installed on jack up unit, and dolly is arranged on girder, and dolly top is provided with hydraulic cylinder, dolly below is connected with suspender, and suspender two ends are connected with workpiece.
Further, on described hydraulic cylinder, hydraulic stem is installed.
Further, described middle supporting leg is fixed on traveling mechanism of the larger traveller.
Further, on described front leg strut, electric box is installed.
Further, on described rear support leg, electric box is installed.
The beneficial effects of the utility model are, this patent in the process of walking, road conditions and geographical environment are required loose, the supporting leg walking of can stretching, in handling process, balance is good, has avoided potential safety hazard, overall structure is novelty simply, operates easy-to-use.
