A kind of synchronous plastic coating production equipment for inner and outer walls of steel pipes

Abstract

A synchronous plastic coating production device for the inner wall and the outer wall of a steel pipe comprises rotating, transmitting, supporting and pushing parts, an inner spraying system, a heating system and an outer spraying system. Each transmitting, supporting and pushing part comprises a supporting plate, wherein the cross section of the supporting plate is in a V shape, two sliding wheels are arranged on the two sides of the supporting plate, at least one sliding wheel is connected with a drive motor, and an included angle is formed between the vertical center of each sliding wheel and the vertical line of the vertical supporting plate. The inner spraying system comprises a circulation inner spraying walking trolley and a spray rod assembly arranged on the circulation inner spraying walking trolley. The heating system comprises a heating tank, and a penetrating hole is formed in the middle of the heating tank. The outer spraying system comprises a spraying box, and an outer spraying pipe is arranged in the spraying box. The synchronous plastic coating production device has the capability of synchronous plastic coating of the interior and the exterior of the pipe and also has the independent running function, plastic coating required by various technologies can be achieved, the assembly line work is adopted, and the production efficiency is high; and the spraying quality technical index can be subjected to parameterization control, and the quality is stable.

Description

technical field [0001] The invention relates to a plastic coating production equipment, in particular to a synchronous plastic coating production equipment for the inner and outer walls of a pipeline. Background technique [0002] At present, for various pipes, such as water supply and drainage pipes, heat pipes, gas pipes, oil pipelines, etc., when making internal and external plastic coatings, manual spraying is often used and then heated and solidified, and the parts are released after cooling. The working environment of manual spraying is poor, and the quality depends entirely on the operator's control and instability. The conveying methods are mostly hoisting, rollers, crawlers, and chains; the steel pipe is heated first, then hoisted on the rollers and rotated for inner wall spraying, and then driven by crawlers or chains to the outer spraying center for outer wall spraying, and the inner and outer walls are sprayed. After entering the heating and curing furnace for c...
