Description

Technical Field

[0001] The invention relates to the field of cable tray printing, and in particular to an automatic high-altitude printing device for cable tray identification. Background Art

[0002] Cable tray is a device that supports, protects and manages cables. It has the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. It provides certain physical protection for cables to prevent them from being damaged by external factors. It is often used for cable outlets in distribution rooms, and the application environment is mostly on the underground floor.

[0003] Cable trays are mostly used to store high-voltage and low-voltage cables. Due to the complex underground environment, most cable trays intersect with other cable trays. Therefore, relevant electrical markings, such as cable directions, high-voltage cables, and low-voltage cables, need to be sprayed after the cable trays are installed. The cable markings on some cable trays have become blurred due to a long installation time and need to be re-sprayed. The commonly used cable marking spraying or maintenance method is manual spraying, which requires a group of 2-3 people to use the prepared marking molds and stand on a ladder to spray manually. It is not only time-consuming and labor-intensive, but also wastes labor and is inefficient. There are major safety hazards in high-altitude operations, such as unstable scaffolding and improper operation, which may lead to accidents.

[0004] The prior art application with the publication number CN219615842U discloses a bridge identification spraying device, which uses the magnetic effect of a magnet bar to adsorb the bridge equipment to be sprayed together; however, it is not possible to print on the cable bridge in the sky. Currently, there is a lack of an automatic printing device that can adjust the height. Summary of the invention
