Trackless deformation gantry crane

Abstract

The invention relates to a trackless deformation gantry crane. The trackless deformation gantry crane comprises a rack (1). The two sides of the rack are both provided with guide supporting pipes (1b). The two sides of each guide supporting pipe are both slidably connected with horizontal guide pipes (2). Each horizontal guide pipe is connected with a vertical sleeve (3). The lower side of each vertical sleeve (3) is connected with a supporting pipe (5) in a sleeving mode. A locking device (6) is arranged between each vertical sleeve and the corresponding supporting pipe. The lower side of each supporting pipe (5) is connected with a traveling device (7). A hoisting device (9) is connected to the rack. The trackless deformation gantry crane has the advantages of being suitable for traveling on flat roads, circular curved surfaces and slopes, capable of steering on the flat roads, the circular curved surfaces and the slopes, meeting the requirement for lateral displacement on curve sectional lines and meeting various height requirements for goods hoisting on various section cross section lines and capable of meeting the requirements for three-dimensional six-degree-of-freedom adjustment of goods hoisting under various working conditions.

Description

technical field [0001] The invention relates to a track laying equipment, in particular to a trackless deformed gantry crane. Background technique [0002] In recent years, my country has gradually become the country with the most railway operating mileage in the world. In order to ensure the high-speed operation of trains, the track structure is required to have a strong integrity. Once the foundation is greatly deformed or the force transmission parts of the track are damaged, the track structure It is difficult to guarantee the stability and smoothness of the train, which may lead to the speed limit of the train, or cause a safety accident. In practical application, during the track construction of railways and subway tunnels, track slabs, sleepers, formwork, rail rows, steel rails and turnouts all need to be hoisted, and track structural components may be damaged during service, and track slabs Or the concrete base plate is cracked, damaged or broken, the high-speed turn...

Problems solved by technology

[0004] The purpose of the present invention is to solve the need to use a crane to cooperate with manual work when changing the track at the present stage, and each construction section must be laid in advance with temporary rails for lifting operations by rail cranes. After the construction is completed, the temporary rails must be removed. Repeatedly doing such additional work is labor-intensive, time-consuming and material-intensive, which not only has a long construction period, but also has disadvantages such as low construction efficiency and poor safety, and a trackless deformed gantry crane is proposed
