Problems solved by technology

[0003] However, the most likely problem when the pipeline is installed on the ground is that it is perishable. To solve this problem, it is common to spray an anti-corrosion coating on the outside of the pipeline, but at present, when spraying the pipeline, it is common to spray the pipeline through the nozzle during the rotation process. Spraying, but in this process, the rotational speed of the pipe and the moving speed of the nozzle will affect the thickness

Embodiment Construction

[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0023] Such as Figure 1-6 As shown, an urban underground pipeline spraying anti-corrosion device includes a lower moving track 1 and an upper moving track 2 .

[0024] The lower moving track 1 is provided with two opposite moving seats 3, and the lower moving track 1 is rotatably connected with two first ball screw screws 11, the moving seat 3 slides on the lower moving track 1, and the two first ball screws The bar 11 is threadedly connected with the two moving seats 3 respectively, and the first ball screw 11 is fixedly connected with the output end of the first motor 12 fixed on the lower moving track 1 .

[0025] The first motor 12 can be used to drive the first ball screw 11 fixedly connected thereto to rotate, and then the rotation of the first ball screw 11 can drive the moving seat 3 to slide on the lower moving track 1 .

[0026] Such as fig...

Abstract

The invention belongs to the field of underground pipeline machining equipment, and particularly relates to an urban underground pipeline spraying anti-corrosion device. The device comprises a lower moving track and an upper moving track, two oppositely-arranged moving seats are arranged on the lower moving track, and fixing mechanisms for fixing a pipeline are arranged on the moving seats. A material spraying mechanism is arranged on the upper moving track, and a first control valve and a second control valve which are used for controlling the material spraying speed are arranged in the material spraying mechanism. The material spraying speed and the material spraying range of a spray head are changed through the rotating speed of the pipeline, the moving speed of the spray head and the distance between the spray head and the pipeline, then automatic adjustment can be achieved in the process, and the spraying uniformity of the pipeline can be accurately ensured without operation of personnel; and therefore, the pipeline has a better spraying effect.

Description

technical field [0001] The invention belongs to the field of underground pipeline processing equipment, and in particular relates to a spraying anticorrosion device for urban underground pipelines. Background technique [0002] Underground pipelines are pipelines laid underground to transport liquids, gases or loose solids. Underground pipelines are arranged below the ground, which can greatly reduce the occupied space of the pipelines, and the setting of underground pipelines can also avoid the gap between pedestrians, vehicles, etc. and the pipelines. In the case of pipeline damage caused by direct contact, and for hot water pipelines, etc., the installation of pipelines underground can also perform functions such as heat preservation, thereby reducing heat volatilization during pipeline transportation. [0003] However, the most likely problem when the pipeline is installed on the ground is that it is perishable. To solve this problem, it is common to spray an anti-corros...
