Problems solved by technology

In the process of bridge erection, the beam and slab components need to be hoisted to the designated position by the crane for installation, but now the cranes are all conjoined structures, and the beams are connected above the crane, so the width of the crane cannot be changed according to the site environment, which is severely limited Lifting scope of the crane

Abstract

The invention relates to a split type girder moving crane. The split type girder moving crane comprises a left crane frame and a right crane frame, wherein the tops of the left crane frame and the right crane frame are provided with winding engines, each winding engine is provided with a fixed pulley group, each fixed pulley group is connected with a movable pulley group, and each movable pulley group is connected with a suspension girder shoulder pole; and the bottoms of the left crane frame and the right crane frame are provided with running mechanisms. During working, a bridge component is firstly fixed on the suspension girder shoulder pole through a hanger, then the winding engines on the left crane frame and the right crane frame are started at the same time after the bridge component is anchored so that the bridge component is raised to an appointed height, then the running mechanisms are started to drive the left crane frame and the right crane frame to move front and back along rails so that the split type girder moving crane moves to an appointed position, then the winding engines are started, and the bridge component is placed at a specific position for installation.

Description

technical field [0001] The invention belongs to the technical field of bridge lifting equipment, and in particular relates to a split beam-moving crane suitable for bridge construction. Background technique [0002] With the needs of my country's economic proposals and the rapid development of China's expressways, there are more and more bridge constructions. As large-scale special equipment in construction, highway bridge erecting machines have become indispensable key equipment in expressway bridge construction. In the process of bridge erection, the beam and slab components need to be hoisted to the designated position by the crane for installation, but now the cranes are all conjoined structures, and the beams are connected above the crane, so the width of the crane cannot be changed according to the site environment, which is severely limited Lifting range of the crane. Contents of the invention [0003] The present invention mainly solves the above-mentioned technic...
