Trackless deformation portal lifting device

Abstract

The invention discloses a trackless deformation portal lifting device which comprises a rack. Sliding holes are formed in the two sides of each end of the rack, a telescopic beam is slidably connectedinto each sliding hole, a horizontal hydraulic cylinder used for controlling the corresponding telescopic beam to slide in the sliding hole is installed in each sliding hole, and the end, away from the corresponding sliding hole, of each telescopic beam is fixedly connected with a vertical pipe; and the lower end of each stand column is fixedly connected with a walking wheel set, an installationbeam is fixedly connected between the two stand pipes at the same side of the machine frame, a storage battery pack and a charging pile are installed on the installation beam, the upper side of the rack is connected with a hoisting device through a transverse adjusting device, and an electric control system and a hydraulic power system are installed on the rack. The trackless deformation portal lifting device has the advantages that the overall width and height of a construction vehicle can be changed, the trackless deformation portal lifting device is suitable for construction of tunnels of different sizes, the inclination angle of wheels can be adjusted so that the wheels can make full contact with the tunnel faces, the steering angle of the wheels can be adjusted, and the trackless deformation portal lifting device is suitable for bent tunnels.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a trackless deformed gantry lifting device. 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,...

[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 turnout is damaged, the cement emulsified asphalt mortar is separated, damaged or cracked, the I-shaped convex stopper and the convex stopper filling resin are damaged, the track slab bearing platform is damaged, The settlement of the overall ballast bed exceeds the limit and other problems. These situations not only affect the beauty of the track, but also directly affect the stability and smoothness of the track structure, thus endangering the safety of train operation. Therefore, it is necessary to repair or replace the track structure components with hidden dangers in time

[0003] The Chinese patent of CN 107140565 A discloses a trackless deformed gantry crane, which meets the walking requirements of various sections and sections. It can not only walk on flat roads, but also walk on medium-arc curved surfaces and slopes, replacing subway tunnels. The internal construction track-type gantry crane saves the temporary rails specially laid during construction, saves construction costs and shortens the construction period, but the trackless deformation gantry crane needs to supply power to its power system during construction in the tunnel, so that the cables will The tow is very long, and it is not particularly convenient to use
