Problems solved by technology
[0002] Large-diameter steel pipes are installed in the prefabricated PC circular pipe gallery. The total length of the pipe is several kilometers or even longer, and the weight of a single pipe section reaches more than 10 tons. The space in the circular PC pipe gallery is small and the ground is also curved. At present, the horizontal transportation is mostly carried out after pouring the flat floor. The sewage materials consume a lot, and it is necessary to wait for the ground strength to meet the requirements before transportation, which takes a long time.

Embodiment Construction
[0046] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0047] A large-diameter heavy-duty steel pipe transportation method in a pipe gallery is based on a large-diameter heavy-duty steel pipe transportation device in a pipe gallery. figure 1 As shown in the figure, the pipeline transportation platform is made of section steel, the ball chassis made of the arc of the pipe gallery is installed on the bottom of the transportation platform, and the pipeline fixing device is installed on the upper part of the platform to ensure that the center of gravity of the pipeline, the center of gravity of the platform and the center of gravity of the ball chassis are on the same vertical plane.
[0048] The pipeline support 6 is arranged on the upper surface of the transportation platform. After the pipeline is placed on the pipeline support 6, the center of gravity of the pipeli...

The invention discloses a method for transporting large-diameter heavy steel pipes in a pipe gallery, which is based on a transport device for large-diameter heavy steel pipes in a pipe gallery. Install the pipe fixing device to ensure that the center of gravity of the pipe, the center of gravity of the platform and the center of gravity of the ball chassis are on the same vertical plane. A lifting device is installed on the transport platform. In this embodiment, the lifting device adopts an electric jack item, and the lifting beam can be opened and closed. Open the beam and hang the pipe on the transport platform. The method of the invention can conveniently and efficiently carry out the horizontal transportation and lifting of the large-diameter heavy steel pipes in the narrow space of the pipe gallery and the upper part of the structure cannot provide a lifting stress point, thereby reducing the labor intensity of workers and improving the transportation efficiency.
Description
technical field [0001] The invention relates to the technical field of large-scale pipeline transportation, in particular to a large-diameter heavy-duty steel pipe transportation method and method in a pipe gallery. Background technique [0002] Install large-diameter steel pipes in the prefabricated PC circular pipe gallery, the total extension of the pipe is several kilometers or even longer, the weight of a single pipe section can reach more than 10t, and the space in the circular PC pipe gallery is narrow, and the ground is also curved. At present, horizontal transportation is mostly carried out after pouring a flat floor, which consumes a lot of dirty materials and needs to wait for the ground strength to meet the requirements before transportation, which takes a long time. SUMMARY OF THE INVENTION [0003] In view of the above technical problems, the present invention proposes a method for transporting large-diameter heavy-duty steel pipes in a pipe gallery, which ca...
