Problems solved by technology
The construction of high-speed railway lines includes the lower track foundation and the upper catenary. When an accident occurs, the specific space and road foundation will bring many problems to the rescue. The existing railway rescue cranes are mostly carried out by setting outriggers on one side of the line. Single-line or adjacent-line operation, the force exerted by the equipment on the bridge foundation during the construction and rescue of some important parts of the high-speed railway line, such as the bridge and culvert section, exceeds the allowable range of its design

Embodiment Construction
[0025] Now further illustrate how the patent of the present invention is implemented in conjunction with the accompanying drawings:
[0026]The high-speed railway rescue crane of the present invention includes a railway crane, a special spreader 9, a flat car 12, and an auxiliary supporting trolley 5. The railway crane includes boarding and disembarking, and the boarding includes an upper turntable 3, a telescopic boom 4, and a lower turntable 2 , telescopic counterweight 1; Getting off comprises chassis 7, supporting leg 11, bogie 15. The lower end of the jacking cylinder in the legs 11 of the crane is a ball joint of a ball joint structure, which can be matched with the ball joint seat on the auxiliary supporting trolley 5 longitudinal beams. The suspension hook of the telescopic boom 4 of the crane can be embedded in the upper beam web of the high-speed rail special suspender 9, and is pinned together with the suspender by two bearing pins crossing the web. Crane lateral m...

The invention relates to a railway crane for high-speed railway and track traffic overline work, which belongs to the field of cranes. In order to meet the safety bearing requirement of high-speed railway bridge-culvert road sections, the railway crane is supported onto protection cushion blocks paved on a roadbed track plate through a trolley track of a transverse moving device which is mounted on a chassis of the railway crane, a trolley is pushed to move by a pipe bending cylinder of the transverse moving device to enable the crane to transversely move to the middle of two adjacent railway lines relative to railway tracks, and spherical hinges at the tail ends of support cylinders of the crane are respectively hinged to a spherical hinge base of a supporting beam of an auxiliary supporting trolley to enable support reaction of crane supporting legs to be distributed onto four wheel groups of a supporting trolley. The acting force on a single-line rail is distributed to the two adjacent railway lines in high-speed railway rescue and construction, cross-line operation of the crane is realized, the safety bearing requirements of high-speed elevated railways and roadbeds and bridge faces of bridge-culvert road sections can be met, and the railway crane is hoisting equipment widely adaptable to various road conditions.
Description
technical field [0001] The invention relates to a railway crane used for cross-line operation of high-speed railway and rail transit, which belongs to the field of cranes, and in particular relates to a high-speed railway rescue crane. Background technique [0002] In recent years, the rapid development of high-speed railways has made a great contribution to the development of my country's transportation, greatly shortening the time, and at the same time reducing the pressure of my country's land and air transportation, and sharing a lot of transportation for my country's existing railways pressure. my country's high-speed railway transportation has entered a stage of rapid development, and the improvement of independent innovation capabilities is the key to the development of high-speed railways to provide fast and safe social services to the people. In order to ensure its safe and effective operation, it is very necessary to develop the corresponding special rescue equipme...
