Description

Technical Field

[0001] The present application relates to the technical field of gantry trucks, and in particular to a movable gantry truck for pipeline corridor construction. Background Art

[0002] During the construction process, pipe gallery structures need to be constructed in many occasions. As an important piece of equipment for pipe gallery construction, pipe gallery trolleys have been widely used in various construction fields. In traditional pipe gallery construction, after the main body of the pipe gallery is cast, construction must continue inside the pipe gallery. The newly cast pipe gallery is long and deep, and there are no mature construction conditions. The light inside the corridor is dim. The problem faced when installing positioning brackets inside the corridor is that tedious installation procedures need to be carried out in a dim environment, especially when measuring the spacing between positioning brackets. Obviously, this is a troublesome practical problem. This problem increases the difficulty of positioning the pipe gallery brackets and has a certain impact on the construction progress, thus requiring a movable trolley to assist in movement.

[0003] Through searching, Chinese patent announcement number CN219118230U discloses a pipe gallery trolley with auxiliary bracket positioning installation. The steel formwork body of the pipe gallery trolley with auxiliary bracket positioning installation adopts steel formwork ridges through design according to the requirements of the drawings, so that the concrete is provided with bracket positioning grooves after pouring, which directly eliminates the positioning process of the bracket installation, improves the convenience of the pipe gallery bracket installation, and speeds up the construction progress.

[0004] Regarding the above-mentioned related technologies, the inventors found the following defects: 1. The horizontal width of the existing gantry is fixed and cannot be adjusted in real time according to the need to move the pipeline corridor. Therefore, each type of pipeline corridor needs to have a separately customized gantry model during the construction process, which reduces the versatility of the gantry.

[0005] 2. Since the jacking components of the existing gantry trucks are customized models, the models of the jacking components cannot be replaced in real time according to the models and sizes of different pipe corridors, which reduces the convenience of using the gantry trucks.
