A protection device based on sand blowing and spraying on the mounting edge of the casing

Abstract

The invention discloses a protection device based on sandblast spray coating of casing installation edge spigots. The protection device based on the sandblast spray coating of the casing installationedge spigots comprises a protection mechanism and a loading and unloading mechanism, wherein the protection mechanism is composed of a fixed bottom seat, a first rotation cavity, a rotation motor, a first belt pulley, a first rotation shaft, a second belt pulley, a rotation plate, a bottom baffle, a first support pillar, a fixed installing seat, an electric telescopic rod, a second support pillar,fixed clamp grooves, a protection barrel, a clamping air cylinder, resetting clamp grooves, fixed clamp plates, a first electromagnet, a driving case, a switching motor, a driving worm, a driving worm wheel and a switching shaft. The protection device based on the sandblast spray coating of the casing installation edge spigots avoids manual clamping, is convenient and quick, saves trouble and labor, can enable a casing to rotate through the rotation motor so as to perform spray coating on the casing in work due to the fact that the rotation motor and the switching motor are arranged, improvesprocessing efficiency of the spray coating, and cannot influence normal use of a non-spraying face of the casing and achieves an adequate protection function for the casing in the sandblast spray coating process.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device based on sand blowing and sand spraying at the edge of the casing installation, and belongs to the technical field of sand blowing and spraying. Background technique [0002] In the production process of the gas turbine casing, sand blasting and spraying treatment is required, and the front and rear mounting edge spigots of the compressor casing need to be sand blasted and sprayed. The two ends of the interior need to be protected during the spraying process. The existing protection device is not convenient for loading and unloading the casing, and manual clamping cannot be avoided. During sand blowing and spraying, it will affect the normal use of the non-sprayed surface of the casing, and cannot fully protect the casing. Contents of the invention [0003] The object of the present invention is to provide a protection device based on sandblasting and sand spraying on...
