Description

Technical Field

[0001] This utility model belongs to the field of petroleum storage and maintenance technology, and more specifically, it relates to a spraying device for corrosion protection of the outer wall of oil tanks. Background Technology

[0002] Currently, the main methods for anti-corrosion spraying of large oil tanks rely on either spider-like workers operating at heights or scaffolding. Workers use scaffolding erected around the exterior of the tank as a working platform for painting and maintenance. The larger the tank, the more time is spent erecting the scaffolding. After the scaffolding is erected, workers wearing spray painting equipment perform the painting and maintenance work. This method has drawbacks such as long maintenance cycles, health hazards, and the fact that painting, scaffolding erection, and dismantling are all high-altitude operations, posing significant safety risks.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spraying device for corrosion protection of the outer wall of oil tanks, in order to achieve a more practical purpose. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a spraying device for corrosion protection of the outer wall of oil tanks, thereby solving the problem of high safety risks in the painting and maintenance of large oil tanks.

[0005] The purpose and effect of this utility model, a spraying device for corrosion protection of the outer wall of oil tanks, are achieved by the following specific technical means:

[0006] A spraying device for corrosion protection of the outer wall of an oil tank includes two sets of slide rails, which are respectively installed at the top and bottom of the outer wall of the oil tank. Each slide rail has a sliding seat slidably disposed therein, and the two sliding seats are connected by a connecting frame. A movable frame is vertically slidably disposed on the connecting frame, and a spraying device is mounted on the movable frame. The movable frame moves up and down by a drive mechanism. A main shaft passes through the sliding seat. One end of the main shaft is driven by a first motor, and the other end is provided with a spline gear. Multiple twisted gears are arrayed on the inner sidewall of the slide rail, and the spline gears mesh with the corresponding twisted gears.

[0007] Furthermore, the drive mechanism includes a chain, and sprockets are rotatably mounted on the top and bottom of the connecting frame. The two sprockets are connected by the chain. The movable frame includes a platform that is slidably mounted on the connecting frame. A spraying device is installed on the platform. An L-shaped transmission plate is provided on one side of the platform. A movable groove is opened laterally on the transmission plate, and a transmission block is slidably mounted in the movable groove. The transmission block is rotatably connected to one of the chain links on the chain, and one of the sprockets is driven by a second motor.

[0008] Furthermore, one side of the slide rail is U-shaped, and two tracks are symmetrically arranged inside the U-shaped cavity. A pulley is engaged between the two tracks, and the pulley is sleeved on the main shaft.

[0009] Furthermore, the slide block is a hollow frame, and a notch is provided on the inner side of the slide block to be locked onto the edge of the slide rail, and the main shaft passes through the hollow frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The connecting frame can rotate around the outer circumference of the oil tank by means of the sliding rails installed at the bottom and top of the oil tank. The lifting and lowering of the moving frame can drive the spraying equipment to carry out spraying work at various positions around the oil tank, making anti-corrosion spraying more convenient, eliminating the need for manual high-altitude operations, and making it safer and more reliable.

[0012] 2. The first motor drives the spline gear to rotate. The spline gear and the torsion belt make the movement of the slide more stable, overcoming the problems of slippage and wear of the roller rotating on the guide rail, and extending the service life. Attached Figure Description

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a spraying device for corrosion protection of the outer wall of an oil tank, including two sets of slide rails 2, which are respectively installed at the top and bottom of the outer wall of the oil tank 1. Each slide rail 2 has a sliding seat 7 slidably disposed therein. Figure 2 and Figure 4 As shown, one side of the slide rail 2 has a U-shaped cavity, and two tracks 201 are symmetrically arranged inside the U-shaped cavity. A pulley 702 is locked between the two tracks 201. A main shaft 701 is inserted inside the slide seat 7. The pulley 702 is sleeved on the main shaft 701. The two symmetrical tracks 201 restrict the position of the slide seat 7. The slide seat 7 then follows the sliding 702 and moves around the oil tank 1 in a circle within the annular track 2.

[0027] Among them, the inner side wall of one side of the pulley 702 is adapted to the curvature of the inner side wall of the circular track 201 to avoid the pulley 702 from rubbing and getting stuck with the inner wall of the track 201 when it moves.

[0028] The two slides 7 are connected by a connecting frame 3, which allows the two slides 7 and the connecting frame 3 to move simultaneously. A movable frame 5 is vertically slidably mounted on the connecting frame 3, and a spraying device 6 is installed on the movable frame 5. The connecting frame 3 moves around the circumference of the oil tank 1, and the movable frame 5 moves up and down, which can drive the spraying device 6 to perform spraying work at various positions around the oil tank 1. Anti-corrosion spraying is more convenient, eliminates the need for manual high-altitude operations, and is safer and more reliable. The spraying device can be composed of a paint tank, pipelines, nozzles, and a pump. The pump carries the anti-corrosion paint from the paint tank through the pipeline to the nozzle for spraying. This spraying device is existing technology and will not be described in detail.

[0029] like Figure 3 As shown, the movable frame 5 moves up and down via a drive mechanism, which includes a chain 4. Sprockets 401 are rotatably mounted on both the top and bottom of the connecting frame 3, and the two sprockets 401 are connected by the chain 4. The movable frame 5 includes a platform 501 slidably mounted on the connecting frame 3. A spraying device 6 is mounted on the platform 501. An L-shaped transmission plate 502 is provided on one side of the platform 501. A transverse movable groove 503 is opened on the transmission plate 502, and a transmission block 504 is slidably mounted within the movable groove 503. The transmission block 504 is rotatably connected to one link of the chain 4. One of the sprockets 401 is driven by a second motor. A U-shaped plate can be installed on the connecting frame 3 at the location of the sprocket 401. The sprocket 401 is located within the cavity of the U-shaped plate, and the chain 4 passes through openings on both sides of the U-shaped plate. The shaft of the sprocket 401 can be rotatably mounted on the connecting frame 3 at one end and on the U-shaped plate at the other end, increasing the stability of the sprocket 401. Figure 2 For clarity, the U-shaped plate is not shown in the image.

[0030] The second motor drives one of the sprockets 401 to rotate, and the chain 4 can drive the moving frame 5 to move up and down through the transmission plate 502. In this embodiment, a slide bar is vertically arranged inside the connecting frame 3, and the moving frame 5 is slidably locked in the slide bar.

[0031] like Figure 4 and Figure 5 As shown, one end of the main shaft 701 is driven by the first motor 704, and the other end is provided with a spline gear 703. Multiple twisted gears 8 are arrayed on the inner sidewall of the slide rail 2. The spline gear 703 meshes with the corresponding twisted gear 8. The first motor 704 drives the main shaft 701 to rotate. Originally, it would move on the track 201 by driving the pulley 702 to rotate. However, in this embodiment, the pulley 702 plays a limiting role and slides only between the two symmetrical tracks 201. The spline gear 703 drives the slide block 7 to move stably through the meshing twisted gear 8, avoiding the slippage of the pulley 702 and affecting the movement efficiency. There is no need to worry about the slippage and wear of the pulley 702, thus extending its service life.

[0032] Among them, slide 7 is a hollow frame, such as Figure 2 and Figure 4As shown, the slide block 7 has a notch on its inner side that is corresponding to the edge of the slide rail 2. The main shaft 701 passes through the hollow frame. The design of the hollow frame reduces the weight of the slide block 7 while ensuring the structural strength of the slide block 7.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
