Embodiment Construction
[0015] The present invention is further set forth below through the accompanying drawings of the description;
[0016] according to figure 1 , figure 2 , image 3 As shown, a double main girder gantry type bridge erecting machine walking device includes a front outrigger 6 and a rear outrigger 1 under the two ends of the main girder 3, a middle outrigger 4 is arranged in the middle of the main girder 3, and the front outrigger The leg 6 and the rear leg 1 are respectively provided with a lifting device 7, so that on special road conditions, they are not limited by the environment and height space, so that it is easier to pass through, and the lifting device 7 is equipped with a hydraulic cylinder 9, so that The walking process is stable and balanced. The trolley 2 is installed on the main beam 3, and a hydraulic cylinder 9 is installed above the trolley 2, so that the balance is good during the lifting process. The bottom of the trolley 2 is connected with a spreader 10, an...

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 [0001] The invention relates to the field of railway mechanical equipment, in particular to a traveling device of a double main girder gantry bridge erecting machine. Background technique [0002] At present, when the bridge erecting machines used in engineering work outdoors, due to the limited geographical environment and insufficient space, they cannot walk and need to disassemble parts; moreover, many bridge erecting machines use motors to drive the reducer to move, which has a large impact , especially when starting, the shaking is large, unstable, and safety accidents are prone to occur. [0003] Therefore, the present invention is developed on the basis of mainly solving the above deficiencies in the prior art. Contents of the invention [0004] The purpose of the invention is to solve the above technical problems, and especially propose a walking device for a double main girder gantry bridge erecting machine that is convenient to walk, strong in st...
