Description

Technical Field

[0001] The invention belongs to the technical field of non-standard machinery, and in particular relates to a prefabricated plate transportation and installation device in a long pipeline. Background Art

[0002] The vacuum tube high-speed train is a new transportation system that uses long pipelines and bridge deck systems as carriers, uses superconducting magnetic levitation technology to achieve train separation from the ground, thereby eliminating friction resistance, and uses internal pipelines close to vacuum to greatly reduce air resistance, ultimately achieving a theoretical train speed of more than 1000km / h. Among them, prefabricated panels are one of the core parts of the bridge deck system. The relevant technologies of prefabricated panel transportation and installation devices are currently representative of the following aspects:

[0003] (1) The patent "A Convenient Concrete Precast Panel Transport Device" (patent number CN215851344U) provides a convenient concrete precast panel transport device, which can complete the transportation and unloading of precast panels, increasing the convenience of precast panel transportation; however, during the unloading process, this mechanism cannot transport the precast panels to the designated location, and does not have intelligent functions such as stopping at the designated location. The subsequent installation of precast panels in long pipelines still requires a lot of manpower and material resources;

[0004] (2) The patent "A prefabricated board transportation fixture and prefabricated board transportation device" (patent number CN212074872U) discloses a prefabricated board transportation fixture and a prefabricated board transportation device, which greatly improves the transportation efficiency and reliability of prefabricated boards in long pipelines, while ensuring the surface quality of prefabricated boards. However, this device simply transports prefabricated boards in long pipelines, and the transportation position needs to be manually controlled. The subsequent installation of prefabricated boards in long pipelines still takes a lot of time;

[0005] (3) The patent "A cement precast panel installation device for bridge construction" (patent number CN212077658U) discloses a cement precast panel installation device for bridge construction, which can raise the precast panel to a specified height to match the installation size, and can also fix the precast panel during installation, thereby protecting the precast panel. However, this device cannot transport the precast panel in the pipeline of a large factory, so the early transportation of the precast panel still requires a lot of manpower and material resources;

[0006] (4) The patent "A cement prefabricated board installation device for bridge construction" (patent number CN213061702U) discloses a cement prefabricated board installation device for bridge construction, which can realize the transmission of the prefabricated board to be installed to the accurate position first, and can adjust the installation angle of the prefabricated board. Compared with manpower, the installation efficiency of the device is greatly improved. However, this device cannot transport prefabricated boards in long pipelines, so the early transportation of prefabricated boards still requires a lot of manpower and material resources.

[0007] Based on the current research on the transportation and installation of precast panels, in order to meet the requirements of reducing the magnetic resistance in the vacuum pipeline magnetic levitation environment and improving the installation efficiency and installation accuracy of precast panels in the bridge deck system in long pipelines, a precast panel transportation and installation device in long pipelines is urgently needed.
