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
[0038] Such as figure 1 As shown, the present invention uses section steel to make the pipeline transportation platform. The bottom of the transportation platform is equipped with a ball chassis made according to the arc of the pipe gallery, and the pipeline fixing device is installed on the top 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.
[0039] A transportation device for large-diameter heavy steel pipes in a pipe gallery, including:
[0040] The bottom of the transport platform is provided with an arc-shaped chassis that matches the inner arc of the pipe gallery, and the arc-shaped chassis is rollingly connected to the inner wall of the pipe gallery through the mobile unit;
[0041] The pipeline support 6 is arranged on the upper surface of the transport platform. After the pipeline is placed on the pipeline support 6, the center of...

The invention discloses a transportation device for large-diameter heavy steel pipes in a pipe gallery, which includes a transportation platform, a ball chassis made according to the arc of the pipe gallery is installed at the bottom of the transportation platform, and a pipe fixing device is installed on the upper part of the platform to ensure the center of gravity of the pipe and the center of gravity of the platform It is on the same vertical plane as the center of gravity of the ball chassis. A lifting device is installed on the transport platform, and the beam in the present invention can be opened and closed. Open the beam and hang the pipe on the transport platform. The device of the invention can conveniently and efficiently carry out the horizontal transportation and lifting of large-diameter heavy steel pipes in a 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 transportation efficiency.
Description
technical field [0001] The invention relates to the technical field of large-scale pipeline transportation, in particular to a transportation device for large-diameter heavy steel pipes in a pipe gallery. Background technique [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, horizontal transportation is mostly carried out after pouring flat floors, which consumes a lot of sewage materials, and it is necessary to wait for the ground strength to meet the requirements before transportation, which takes a long time. Contents of the invention [0003] In view of the above technical problems, the present invention proposes a transport device and method for large-diameter heavy steel pipes in the pipe gallery,...
