Paint spraying device for cutter base body of shield tunneling machine

Abstract

The invention discloses a paint spraying device for a cutter base body of a shield tunneling machine. The paint spraying device comprises a box body, a paint spraying chamber is arranged in the box body, a partition plate is arranged on the left side of the paint spraying chamber, a fixing mechanism is arranged on the partition plate, the cutter base body is fixed to the fixing mechanism, a rotating motor is arranged on the left side of the partition plate, the output end of the rotating motor penetrates through the partition plate and is connected with the fixing mechanism, an arc-shaped first sliding rail is fixed to the top of the paint spraying chamber through a vertical rod, a sliding block is mounted on the first sliding rail in a sliding mode, and an electrostatic spraying head is fixed to the bottom of the sliding block. The cutter base body is fixed through the fixing mechanism, and then the cutter base body is driven to rotate through the rotating motor, so that the spraying effect is more uniform; the electrostatic spraying head is arranged on the arc-shaped first sliding rail in a sliding mode and slides back and forth for spraying of the surface of the cutter base body, it can be guaranteed that all the surfaces can be evenly painted, the spraying effect is good, and the probability of later supplementary spraying is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of shield machine tool processing equipment, in particular to the technical field of a shield machine tool substrate painting device. 【Background technique】 [0002] The shield machine is a special engineering machine used for the excavation of subway tunnels, drinking water projects, and river-crossing tunnels. It has the functions of excavating and cutting soil, conveying soil muck, assembling tunnel lining, and measuring and guiding deviation correction. It is mainly used for urban subway construction Units, railway road tunnels and drinking water projects, etc. Various knives such as edge scrapers, cutters, leading knives, shell knives and hobs are installed on the shield machine cutter head. The shield machine cutter is a cutting tool for the cutterhead of the shield machine. It is installed on the spoke base of the cutterhead of the shield machine and rotates with the cutterhead together with other ...
