Description

Technical field [0001] The present invention belongs to the field of high-speed maglev track construction technology, specifically relates to a kind of rail beam lifting equipment suitable for high-speed maglev. Background [0002] With the continuous development and accumulation of maglev technology in China, the design and research of related maglev rail transit lines are increasing, and the requirements for related supporting technologies are also higher. In the construction process of high-speed maglev track lines, the construction of rail beams for them is a very important process. [0003] In the construction process of high-speed maglev rail beams, it is often necessary to use large lifting mechanisms to assist in construction. However, due to the different forms of tracks, conventional rail beam lifting devices are often not directly used for the lifting of high-speed maglev track T-beams. Moreover, in the construction process of the track beam, there will also be tunnel...

Problems solved by technology

However, due to the different track forms, conventional track beam lifting devices often cannot be directly used for lifting construction of high-speed maglev track T-beams

Moreover, during the construction of track beams, construction in tunnels and underground spaces will also be encountered. At this time, due to the limited working space, it is often difficult for conventional lifting mechanisms to set up and complete the hoisting of maglev turnouts and beam mechanisms beside the track operation, resulting in difficulties in the installation of the beam body of the maglev track

In addition, in the above-mentioned working environment with limited space, even if the hoisting mechanism can enter the site, the telescopic height of the hoisting equipment is limited and the control process is cumbersome because of the need to avoid collisions with surrounding walls and equipment, and avoid intrusion.

[0004] In addition, the turnout beam of the high-speed maglev track is usually large in size, with a total length of nearly 80m, a width of nearly 3m, and a switch distance of nearly 4m.

Moreover, high-speed maglev track beams require high installation accuracy, and it is necessary to ensure one-time clamping and positioning during the installation process, and to ensure millimeter-level installation accuracy, including limit positioning accuracy and pulling butt joint accuracy, which undoubtedly puts forward more challenges for the hoisting of track beams. High requirements, resulting in the existing equipment can not meet the needs of practical applications
