Description

Technical Field

[0001] The present invention relates to the technical field of subway trolleys, and more particularly, to a disassembly-free multi-functional assembly trolley applicable to fully prefabricated subway stations. Background Art

[0002] Prefabricated construction technology has the advantages of high efficiency, little constraint by climate conditions, and labor saving, and has been widely applied to various public buildings and civil buildings. In recent years, prefabricated construction technology has also been gradually applied to subway station construction. Prefabricated components are uniformly manufactured in factories, and the construction of the entire station is completed by means of assembly, which greatly reduces the on-site construction time, reduces energy consumption, and thus reduces construction costs. Prefabricated stations conform to the development trend of modern prefabricated industrialization, can better meet the needs of various construction environments, meet the requirements of subway green construction and energy conservation, improve construction quality and efficiency, and more effectively ensure construction quality and reduce costs. In future subway construction, prefabricated technology will play a very important role.

[0003] Currently, during the construction of fully prefabricated subway stations, a support trolley is also used to assemble prefabricated components. However, during construction with the existing trolleys, all components of the trolley need to be transported to the construction site and assembled in a deep foundation pit. Since the overall length, width, and height of the trolley are all in the range of more than ten to more than twenty meters, the overall assembly of the machine takes a long time, has high technical requirements for assembly workers, requires rework when assembly errors occur, which affects the construction progress, and may even result in large errors in the assembly of prefabricated components, affecting the construction quality. After the assembly of the overall prefabricated components is completed, the trolley needs to be disassembled and transported one by one, and the construction efficiency is low.

[0004] The existing Chinese invention patent, a assembly trolley for a cut-and-cover subway station using prefabricated components (application number: CN201621130371.2), includes a main frame and a top assembly frame installed on the main frame; the top assembly frame is composed of kinematic pairs of upper, middle, and lower three-layer gantries, and longitudinal and lateral sliding can be completed between the three layers, and the assembly of blocks C, D, and E of the station is completed through the operation of a hydraulic system. When adjusting the positions of blocks C, D, and E of the station, the three-layer gantries need to work together, and more refined adjustment cannot be completed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is:

[0006] To solve the problems that the existing trolleys are non-integral, need to be assembled and disassembled at the construction site, which affects the construction efficiency, has high technical requirements for construction workers, is prone to assembly errors of prefabricated components, affecting the construction quality; and requires the joint adjustment of the three-layer gantries to complete the adjustment in different directions of blocks C, D, and E, with poor adjustment accuracy.

A plurality of foldable legs 1 and a plurality of universal wheels 2 are evenly arranged on the lower end surface of each frame longitudinal beam 7. The foldable legs 1 are hinged to the frame longitudinal beams 7, and the foldable legs 1 and the lower end surface of the working platform 8 are connected by leg hydraulic telescopic rods 3, which are used to store the foldable legs 1 under the working platform 8. When the trolley is placed on a plane, it can move through the universal wheels 2, facilitating the movement and transportation of the whole trolley; the frame longitudinal beams 7 and the universal wheels 2 are connected by universal wheel hydraulic telescopic rods;

[0043] The lower end of the foldable leg 1 is provided with a traveling mechanism 5. The traveling mechanism 5 includes a traveling wheel fixing frame 5-3. A plurality of traveling wheels 5-1 and a driving motor 5-2 are arranged at the lower end of the traveling wheel fixing frame 5-3. The traveling wheels 5-1 are arranged on a traveling slide rail 6 built on a B-block precast member. The driving motor 5-2 is used to drive the traveling wheels 5-1. A braking motor 5-5 and a braking telescopic rod 5-4 are arranged inside the foldable leg 1. When it is necessary to brake the traveling wheels 5-1, the braking telescopic rod 5-4 is extended by the braking motor 5-5 to abut against the connecting rod between the traveling wheels 5-1, stopping the rotation of the traveling wheels 5-1. The trolley can be controlled to travel and brake along the traveling track 6 through the driving motor 5-2;

[0044] The top assembly frame includes at least two layers of assembly frames. On the upper end surface of the topmost assembly frame, there are several stepwise arranged walking jacks 16.
