Abstract
The invention provides a double-girder portal type running device of a bridge girder erection machine. The double-girder portal type running device is characterized in that front landing legs and rear landing legs are arranged below the two ends of girders, a middle landing leg is arranged in the middles of the girders, lifting devices are arranged on the front landing legs and the rear landing legs respectively and provided with hydraulic cylinders, a trolley is installed on the girders, a hydraulic cylinder is arranged on the trolley, a lifting tool is connected below the trolley, and workpieces are connected to the two ends of the lifting tool. When the double-girder portal type running device is in the running process, requirements for the road conditions and the geographical environment are low, the landing legs can run in a stretchable mode, the balance is good in the lifting process, potential safety hazards are avoided, and the double-girder portal type running device is simple and novel in overall structure and convenient to operate and use.
Description
Technical field
The present invention relates to railway machinery apparatus field, particularly a kind of two 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 startup, rocking property is large, unstable, and security incident easily occurs.
Therefore, the present invention develops on the basis that mainly solves more than currently available technology existence deficiency.
Summary of the invention
The object of invention 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, technical problem solved by the invention realizes by the following technical solutions:
A kind of two 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 invention has the beneficial effects as follows, 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.
