Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] figure 1 A side view of a turntable 10 for a bridge erecting machine according to the invention is shown. Such as figure 1 As shown, the turntable 10 includes a bottom frame 1 and a top frame 2 buckled on the bottom frame 1 . A device for making the top frame 2 rotatable relative to the bottom frame 1 is provided between the bottom frame 1 and the top frame 2, which will be described in detail below. In the construction process, the bridge erecting machine is arranged on the top frame 2, and the bottom frame 1 is fixedly arranged. For example, the underframe 1 can be arranged on a bridge pier. By pushing the bridge erecting machine, the direction of the bridge erecting machine can be adjusted by means of the rotation of the top frame 2 relative to the bottom frame 1 .

[0022] Both the bottom frame 1 and the top frame 2 are plate-shaped steel plates, such as cir...

Abstract

The invention discloses a rotating disc for turning a whole bridge girder erection machine. The rotating disc comprises a chassis and a top rack which is movably mounted on the chassis in a buckled manner, wherein a first plane where the top rack exists is parallel to a second plane where the chassis exists; the top rack can rotate in the first plane relative to the chassis and does not deviate from the chassis. During construction, the rotating disc disclosed by the invention can be utilized to conveniently rotate the bridge girder erection machine.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a turntable for integral steering of a bridge erecting machine. Background technique [0002] In the process of bridge construction, the bridge erecting machine is an indispensable equipment. The bridge erecting machine is used to place the prefabricated girders on the prefabricated piers, and adjust the position of the girders so that they are accurately connected with the already set girders or other parts of the bridge. [0003] In order to adjust the direction of the bridge erecting machine conveniently, it is usually necessary to dismantle the bridge erecting machine and reinstall it. In the process of dismantling and reinstalling, cranes and gantry cranes are required to lift the dismantled parts and transport them to the designated place for reinstallation by dump truck. This greatly increases the construction cost of the bridge hoisting operation and prolongs the c...
