Abstract
The utility model provides a double-girder gantry type bridge erection machine which is characterized in that a front supporting leg and a rear supporting leg are arranged on the lower parts of two ends of a girder; a trolley runs on the girder; a hydraulic cylinder is arranged on the trolley; a lifting appliance is connected to the lower part of the trolley; workpieces are connected to two ends of the lifting appliance; a middle supporting leg is arranged in the middle of the girder and is fixed on a crane travel mechanism. The bridge erection machine is simple and novel in structure, convenient to operate and use, good in balance during operation, high in safety and convenient to lift, and an object cannot shake.
Description
Technical field
The utility model relates to railway machinery apparatus field, particularly a kind of two girder gate-type Bridge Erector.
Background technology
At present, the Bridge Erector using in engineering is in the time of handling object, the general dolly connecting steel wire ropes delivery object that adopts moves back and forth on girder, but wire rope is easily uneven in the time of work, rocking property is large, easily there is wire cable rupture or object and fall, damage body or the workman that wounds, produce security incident.
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 novel structure, safety is large, balance is good two girder gate-type Bridge Erectors.
Based on above-mentioned purpose, the technical problem that the utility model solves realizes by the following technical solutions:
A kind of two girder gate-type Bridge Erector, comprise that below, girder two ends is provided with front leg strut and rear support leg, on girder, operation has dolly, described dolly top is provided with hydraulic cylinder, dolly below is connected with suspender, suspender two ends are connected with workpiece, in the middle of girder, are provided with middle supporting leg, and middle supporting leg is fixed on traveling mechanism of the larger traveller.
Further, described hydraulic cylinder is fixed on dolly.
Further, described suspender is connected with dolly by connecting rod.
Further, described suspender is 360 degree rotations.
Further, described front leg strut height can pass through jack up unit free adjustment.
The beneficial effects of the utility model are, this patent overall structure is simply novel, operate easy-to-usely, and balance is good in the course of the work, and object does not rock, and security performance is high, handling is convenient.
