Embodiment Construction

[0027] In order to ensure uniform coating and improve spraying quality, the present invention provides an adjustment device, which includes: a radial adjustment component, one end of the radial adjustment component is connected to one end of the first mounting plate; a spray gun, the One end of the spray gun is connected to the other end of the first mounting plate; the walking part is connected to the other end of the radial adjustment part; the rotating support arm is connected to the radial adjustment Between one end of the component and the other end of the radial adjustment component, wherein, when the device is spraying the pipeline, the walking component is close to the surface of the pipeline, and the radial adjustment component automatically radially adjusts the spray gun. The distance is adjusted so that the distance between the spray gun and the surface of the pipe is always consistent during the spraying process, ensuring the spraying quality.

Abstract

The invention discloses an adjusting device. The adjusting device comprises a radial adjusting part, a spray gun, a travelling part and a rotary support arm, wherein one end of the radial adjusting part is connected with one end of a first mounting plate, one end of the spray gun is connected with the other end of the first mounting plate, the travelling part is connected with the other end of the radial adjusting part, and the rotary support arm is connected between two ends of the radial adjusting part. When the adjusting device is arranged on a spray pipeline, the travelling part clings to the surface of the pipeline, the radial adjusting part can automatically adjust radial distance of the spray gun, and the distance between the spray gun and the pipeline surface is always kept uniform during spraying, so as to ensure spraying quality. Accordingly, the coating is uniform and spraying quality is improved.

Description

technical field [0001] The invention belongs to the technical field of oil and gas pipeline welding joint spraying, and in particular relates to an adjusting device. Background technique [0002] After the oil and gas pipeline welder, the joint part of the pipeline needs to be coated and repaired. At present, the most widely used is to use liquid polyurethane spraying equipment to spray the joint part of the pipeline. [0003] Liquid polyurethane spraying equipment uses a rotatable device to spray on the surface of the pipe. Due to the ellipticity of the pipe itself and the assembly gap between the pipe and the rotating device, there will be a gap between the spray gun and the surface of the pipe during the rotation of the rotating device. The frequent changes in the distance of the coating lead to uneven coating, which affects the quality of spraying and increases the loss of coating. [0004] Based on this, in order to improve the quality and efficiency of spraying, a sp...
