Description

Technical Field

[0001] This utility model relates to the field of outdoor spraying technology, and in particular to an automatic spraying device for vertical pressure vessels. Background Technology

[0002] Outdoor vertical pressure vessels are vertically placed pressure vessels used in outdoor environments. They are mainly used for storing and transporting various high-pressure, high-temperature, and corrosive media. In the petrochemical industry, many pressure vessels require on-site welding and assembly before painting. Currently, the painting process for outdoor vertical pressure vessels is basically manual. During the painting process, the paint can harm the physical and mental health of the operators, and the process requires repeated climbing up and down the scaffolding for high-altitude work, making the entire operation risky. Using a support frame to replace manual painting is limited by the structure of the frame itself, making it difficult to complete the entire painting process in one go. Therefore, it is necessary to design an automatic painting device for vertical pressure vessels. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic spraying device for vertical pressure vessels, which solves the problem that the current spraying process for outdoor vertical pressure vessels basically requires manual operation. During the spraying process, the paint can harm the physical and mental health of the operators. At the same time, the process requires repeated climbing up and down the high frame for high-altitude work, which is very risky. Using a bracket to replace manual spraying is limited by the structure of the bracket itself, making it difficult to complete the entire spraying process in one go.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vertical pressure vessel automatic spraying device, including a drive trolley, an automatic hook assembly, an I-beam guide rail, a top pressure wheel, a lifting bracket, a lifting hydraulic cylinder, a top platform, a spraying adjustment assembly, a spray nozzle, a material conveying pipe, and a paint tanker. A first cylinder of the automatic hook assembly is installed on one side of the drive trolley. A transverse frame is fixedly connected to the output end of the first cylinder. A second cylinder is fixedly sleeved within the transverse frame. A connecting frame is fixedly connected to the output end of the second cylinder. Hook wheels are uniformly rotatably connected to the bottom of the connecting frame. A lifting bracket is installed at the top, and a lifting hydraulic cylinder is connected in conjunction with the lifting bracket. A top platform is installed at the top of the lifting bracket, and a sliding bracket of the spraying adjustment assembly is installed on the top platform. A sliding screw is rotatably connected to the sliding bracket by a bearing. A sliding block is installed on the sliding screw. A pushing platform is fixedly connected to the top of the sliding block. A first support plate is rotatably connected to one side of the top of the pushing platform. A side support plate is installed on the top of the first support plate. A second motor is fixedly connected to one side of the side support plate. The output end of the second motor passes through the side support plate and is fixedly connected to the second support plate. A spray nozzle is fixedly connected to the second support plate.

[0005] As a further technical solution of this utility model, the automatic hook assembly consists of a first cylinder, a transverse frame, a second cylinder, a connecting frame, and a hook wheel, with the hook wheel rollingly connected to the inner wall of the I-beam guide rail.

[0006] As a further technical solution of this utility model, a top pressure wheel is rolledly connected to the outer wall of the I-beam guide rail, and the top pressure wheel is rotatably connected in the drive trolley.

[0007] As a further technical solution of this utility model, the spraying adjustment component consists of a sliding bracket, a sliding screw, a sliding block, a pushing platform, a slider, a slide rail, a first motor, a first support plate, a side support plate, a second support plate, a second motor, and a screw motor. The sliding block is connected to the sliding screw through an internally embedded ball nut. A slider is fixed at the bottom of the pushing platform, and the slider is slidably connected to the slide rail, which is fixed on the top platform.

[0008] As a further technical solution of this utility model, a lead screw motor is provided on one side of the sliding bracket, and the output end of the lead screw motor is fixedly connected to one end of the sliding lead screw.

[0009] As a further technical solution of this utility model, a first motor is fixedly connected to one side of the bottom of the jacking platform, and the output end of the first motor passes through the jacking platform and is fixedly connected to the bottom of the first support plate.

[0010] As a further technical solution of this utility model, a material conveying pipe is connected to the spray nozzle, and one end of the material conveying pipe is connected to the paint tanker.

[0011] This utility model provides an automatic vertical pressure vessel spraying device, the advantages of which are as follows: During operation, the first cylinder drives the horizontal moving frame to move outward, and then the second cylinder in the horizontal moving frame drives the connecting frame to move downward. The connecting frame then pulls the connecting trolley closer to the drive trolley, causing the hook wheel and the top pressure wheel to roll and connect to both sides of the I-beam guide rail. The I-beam guide rail, distributed in a ring around the pressure vessel, guides the movement of the drive trolley. During the movement of the drive trolley, the height of the spray nozzle is adjusted using a lifting bracket and a lifting hydraulic cylinder. This, combined with the paint tanker, completes the spraying process around the pressure vessel without manual intervention, resulting in low operational risk and avoiding harm to the operator's health from paint. During spraying, a screw motor drives the sliding screw to rotate. The sliding screw, in conjunction with the ball bearing nut embedded inside the sliding block, drives the top pushing platform to move closer to or away from the pressure vessel along the slide rail. Then, the first and second motors respectively drive the first and second support plates to rotate, adjusting the tilt angle of the spray nozzle. This convenient adjustment ensures uniform spraying. The entire spraying process can be completed in one pass, improving the practicality of the device. Attached Figure Description
