Span rail stand structure used for supporting high speed railway wrecking crane

Abstract

The invention provides a span rail stand structure used for supporting a high speed railway wrecking crane, and in particular to the high speed railway wrecking crane. According to the invention, a bearing stand group is composed of two rail supports and a bearing crossbeam, a support lifting bar of the rail support enables lock joint on a rail through a grooved type boot, the bearing crossbeam is connected to a crane supporting leg in a spherical hinge mode through a crane supporting leg piston shoe; the bearing crossbeam is hinged to a rotation hinged support at the upper part of the rail support through a bearing crossbeam slide carriage, so that two ends of the bearing crossbeam moves by relating to the rail support through a chute or is positioned through a pin, two ends of the bearing crossbeam and the rail supports at two sides are adjusted and positioned, and then the crane supporting leg can be supported on a span rail stand in a stable mode. The simple span rail stand structure can effectively disperse the concentrated force on a bridge structure to the rail when a crane works, which solves the problems of large concentration loading force of the crane to the rail, the rescue works can be carried out by a simple operation program, and the work efficiency of the crane is increased.

Description

technical field [0001] The invention patent relates to a cross-rail platform structure used for the support of a railway rescue crane, which belongs to the field of cranes, and particularly relates to a high-speed railway rescue crane. Background technique [0002] At present, my country's high-speed rail trains are still in their infancy. With the development and progress of high-speed rail, the lagging of its supporting equipment will become a bottleneck for the development of high-speed rail. Since the construction of the high-speed rail includes the corresponding under-rail foundation and the catenary above the bow, once an accident occurs, its specific space and road foundation will bring many problems to rescue, which requires better adaptability of rescue equipment. The utilization of space and the selection of bearing points put forward higher requirements. [0003] In the construction process of the entire high-speed railway line, bridges and culverts account for a...

AI Technical Summary

Problems solved by technology

When the high-speed rail crane is performing lifting operations, the fulcrum reaction force of a single outrigger is relatively large. If the outrigger of the crane is directly supported on the foundation or track above the bridge, the concentrated force will threaten the road safety of the high-speed railway.
