Description

Technical Field

[0001] The utility model belongs to the field of high-altitude working facilities under bridges, and specifically relates to a mobile hanging basket for installing pipeline brackets in a highway bridge section. Background Art

[0002] The construction of communication pipelines is an indispensable and important part of highways. It is not only the foundation of the three major electromechanical systems, but also an important guarantee for the communication safety of highways. Therefore, the laying of pipelines is of great significance to the construction of highways. Pipeline supports are set on the outside of highway bridges, where the pipeline supports are located in the middle of the bridge between the two lines. The pipe boxes are mainly used to lay communication silicon core pipelines, and the communication pipelines are protected by polyurethane bridge frames when crossing the bridge. At present, the length of domestic highway bridge sections is generally between 10,000 meters and 20,000 meters. All bridge sections need to be equipped with pipeline supports to install pipe boxes and subsequent communication silicon core pipeline laying. The installation of the bridge supports involved is large, the construction is difficult, the risk factor is high, and it is time-consuming and labor-intensive. In particular, the construction and installation of the supports has always been an important reason restricting the construction progress.

[0003] In the past, the installation of pipeline brackets in the bridge section was done by pre-burying the brackets in the foundation of the bridge guardrail, and fixing the pipe box on the brackets with screws through the brackets pre-buried by the civil engineering unit. Although this method can reduce the workload of mechanical and electrical pipeline bracket installation, it often happens on site that the brackets pre-buried by the civil engineering unit have large errors in the bracket position elevation due to the large amount of work, resulting in large fluctuations after the pipe box is installed. In addition, there are often inconsistencies between the requirements for bracket installation in the civil engineering design drawings and the mechanical and electrical design drawings, which makes it difficult to pass the subsequent physical acceptance. In order to minimize construction errors and complete the installation tasks in a high-quality, efficient, safe and reliable manner, in addition to forming a team of highly qualified construction workers, the construction tools used are also particularly important.
