Description

Technical Field

[0001] The invention belongs to the technical field of transportation devices, and particularly relates to a tunnel steel pipe transportation device with a special bearing beam. Background Art

[0002] At present, during the tunnel construction process, pipeline laying is required. Usually, the pipeline has a large diameter, a long distance, and high construction difficulty. For pipeline laying over a distance of thousands of kilometers, the transportation and laying of large-diameter pipelines are quite difficult. It is necessary to transport the pipelines into the narrow tunnel, lift each pipeline in turn and then align the mouths, and weld adjacent two pipelines into a connected pipeline. Due to the limitation of the space in the tunnel, large equipment such as pipe lifting machines used outside the tunnel cannot enter the tunnel for construction. Therefore, in the existing pipeline laying process, the transportation and adjustment methods of pipelines mainly use simple devices or special equipment. The simple devices and special equipment are suitable for single working conditions, have a low degree of automation, low transportation and adjustment efficiency, and are prone to bumps during the pipeline transportation process and poor docking accuracy.

[0003] Referring to the Chinese patent application with the publication number CN111677534A, it discloses an operation vehicle for tunnel lining pipeline transportation, disassembly and assembly, including a bearing beam and a transportation trolley for supporting the bearing beam to move. A pipeline position and attitude adjustment device is installed on the bearing beam. This invention is provided with a pipeline attitude adjustment device. When the pipeline reaches the installation position, the configured pipeline attitude adjustment device can be used to adjust the attitude of the lining pipeline. When the roundness error of the pipe orifice exceeds the standard, the roundness requirement can be achieved by using a pipe expanding mechanism to support the inner wall of the pipeline, and then the precise docking with the already installed pipeline can be completed. However, the bearing beam of this transport vehicle is fixed and cannot move, and its adaptability to pipelines of different lengths is poor, and no protection device is installed on this transport vehicle, so the safety of construction workers cannot be guaranteed.
