Description

Steel pipe transport vehicle and transport and installation method for steel pipes in cavern space
Technical Field
The invention relates to the technical field of steel pipe transportation, in particular to a steel pipe transport vehicle and a method for transporting and installing steel pipes in a cavern space.
Background
In the construction process of underground engineering caverns, large objects such as steel pipes and the like are often required to be hoisted, and the steel pipes are required to be horizontally transported in the manufacturing and installation engineering process. Because the cavern space is comparatively narrow, so when transporting the steel pipe in the cavern space, receive the restriction of construction site easily, and then, generally adopt the transport vechicle to transport the steel pipe in the cavern space.
When the existing transport vehicle transports the steel pipes in the cavity space, the transport vehicle can only transport the steel pipes on a single road condition, and can not rapidly switch among a plurality of road conditions, for example, the steel pipes are difficult to switch among a plane road condition, an intrados road condition and a local step road condition. Therefore, when the steel pipe is transported in the cavern space by the existing transport vehicle, the track is generally installed in the cavern space, so that the transport vehicle can walk on the track to meet the requirements of the transport vehicle on different road conditions or meet the conversion of the transport vehicle between different road conditions, and the steel pipe is placed at the top of the transport vehicle to transport the steel pipe.
However, the way that the steel pipes are transported by the transport vehicle is realized by installing the rails in the cavern space, so that the construction cost is high and the construction efficiency is low; moreover, after the steel pipes are transported to the designated positions by the existing transport vehicle, due to the limitation of the construction site, the steel pipes are inconvenient to dismount from the transport vehicle, and the transport vehicle can only run on the track, so that the dismounted steel pipes cannot be directly butted with the installed steel pipes in the cavern space, and workers are required to adjust the positions of the transported steel pipes, so that a large amount of labor cost is consumed, and the construction efficiency is low; in addition, the transportation mode of the existing transportation vehicle is used in an environment with a narrower cavern space, namely when the sum of the height of the transportation vehicle and the diameter of the steel pipe is greater than the height of the interior of the cavern space, the steel pipe cannot be transported in the cavern space, and further great troubles are brought to the installation of the steel pipe.
