Description

Technical Field

[0001] The invention relates to the field of spiral steel pipe processing, and in particular to a multi-angle anti-corrosion paint spraying device for spiral steel pipe processing. Background Art

[0002] Spiral steel pipe is a pipe made by welding steel strips or steel coils in a spiral shape. It is widely used in the fields of oil, natural gas, water supply, drainage, etc. Its manufacturing process makes the spiral steel pipe have good mechanical properties and welding properties, which is suitable for high-pressure and large-diameter transportation needs.

[0003] When spiral steel pipes are used to transport media such as oil, natural gas, and water, they are prone to rust when exposed to humid or corrosive environments. Solid spray painting on their surface can form a protective film to prevent moisture and oxygen from contacting the surface of the steel pipe, thereby playing an anti-corrosion role.

[0004] Spiral steel pipes usually need to be clamped and positioned before spraying the inner wall, which can prevent the spiral steel pipes from shifting or rolling during the spraying process, thereby ensuring the uniformity and accuracy of the spraying. In the prior art, according to actual use needs, when replacing spiral steel pipes of different diameters for inner wall spraying, the spraying distance needs to be adjusted each time the replacement is performed. This is because when the spraying distance is appropriate, the paint can better adhere to the surface of the steel pipe and enhance the adhesion of the coating. If the distance is too large, the paint may be affected by air resistance when reaching the surface, reducing the adhesion. The distance between the nozzle and the steel pipe surface will significantly affect the quality of the paint spraying, and adjusting the spraying distance will cause the spraying process to become longer, reducing production efficiency.

[0005] Therefore, it is necessary to propose a multi-angle anti-corrosion painting device for spiral steel pipe processing to solve the above problems. Summary of the invention

[0018] Beneficial Effects

[0019] Compared with the prior art, the present invention provides a multi-angle anti-corrosion paint spraying device for spiral steel pipe processing, which has the following beneficial effects:

[0020] 1. The multi-angle anti-corrosion paint spraying device for spiral steel pipe processing utilizes the elastic force and elasticity of the supporting spring to support the spiral steel pipe. The two positioning columns can move up and down to adapt to the clamping and positioning of spiral steel pipes of different diameters. When the two inclined columns are in contact with the end of the spiral steel pipe away from the vertical plate, the two inclined columns can approach each other, the second spring is further compressed, and the spiral steel pipe will also move toward the direction close to the vertical plate until it contacts the surface of the vertical plate. Then, the two inclined columns will fit with the inner wall of the spiral steel pipe, and the clamping plate will be in close contact with the end of the spiral steel pipe away from the vertical plate. The first spring is gradually compressed to clamp and position the spiral steel pipe. When replacing spiral steel pipes of different diameters for inner wall painting, rapid clamping and positioning can be achieved, thereby improving painting efficiency.

[0021] 2. The multi-angle anti-corrosion paint spraying device for spiral steel pipe processing, when both inclined columns enter the interior of the spiral steel pipe, due to the setting of the friction block, most of the reaction force generated by the compression of the support spring is offset by the friction between the friction block and the L-shaped column, so that the positioning column and the spiral steel pipe can maintain the position when they are clamped and positioned, and when the rotating column is adjusted and rotated, the stability of the T-shaped column and the inclined column can be guaranteed. That is, according to actual needs, when replacing spiral steel pipes of different diameters for inner wall painting, the distance between the drying mechanism and the nozzle and the inner wall of the spiral steel pipe is fixed, and there is no need to adjust the spraying distance every time it is replaced, so as to ensure the quality of the paint spraying, save adjustment time, make the spraying process more efficient, shorten the overall production cycle, and the fixed spraying distance can ensure the consistency of the coating thickness and quality of each steel pipe, improve the uniformity of the coating, and ensure the consistency of the anti-corrosion effect.

[0022] 3. The spiral steel pipe is processed with a multi-angle anti-corrosion paint spraying device. When the two inclined columns enter the interior of the spiral steel pipe, the drying mechanism can dry the inner wall of the spiral steel pipe to remove moisture from the inner wall. The dry surface can better combine with the sprayed paint, enhance the adhesion of the coating, and ensure the uniform thickness of the coating. It can be dried immediately after painting to speed up the curing process of the coating and ensure that the coating is firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that the positioning mechanism 3 can temporarily place and position the spiral steel pipe. When the spiral steel pipe is placed on the surface of the two positioning columns 35, the positioning columns 35, the lifting columns 32 and the support blocks 34 will move downward, and the support spring 33 will be compressed. The elastic force of the support spring 33 can be used to support the spiral steel pipe.

[0039] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The adjusting assembly 52 includes a mounting frame 521 fixedly connected to the right side of the upper surface of the bottom plate 1, a worm gear 522 is rotatably connected to the surface of the mounting frame 521, a worm 523 is meshedly connected to the lower part of the worm gear 522, the worm 523 is rotatably connected to the vertical plate 11, a first motor 524 is fixedly connected to the upper surface of the bottom plate 1 on the left side of the vertical plate 11, the output shaft of the first motor 524 is fixedly connected to the end of the worm 523 away from the worm gear 522, a first adjusting column 525 is meshedly connected to the upper part of the worm gear 522, and the first adjusting column 525 is slidably connected to the mounting frame 521;

[0040] It should be noted that the first motor 524 drives the worm 523 to rotate, the worm 523 meshes with the worm wheel 522, and then drives the worm wheel 522 to rotate, the worm wheel 522 meshes with the first adjusting column 525, and then can drive the first adjusting column 525 to move, the second adjusting column 512 and the first adjusting column 525 are connected by the connecting column 511, the first adjusting column 525 and the second adjusting column 512 move together, the adjusting component 52 can play an adjusting role, by adjusting the first adjusting column 525 and the second adjusting column 512 to move, drive the clamp 513 to clamp the spiral steel pipe; when the distance between the nozzle 47 and the vertical plate 11 is short, the first motor 524 drives the worm 523 to rotate in the opposite direction, and the delivery pump 412 delivers the paint in the storage box 413 to the nozzle 47, and the paint is sprayed out by the nozzle 47 to perform multi-angle painting.

[0041] See also Figure 4 A limiting groove 526 is provided on the surface of the first adjusting column 525, and the mounting frame 521 is slidably connected to the limiting groove 526;

[0042] It should be noted that the limiting groove 526 cooperates with the mounting frame 521 to ensure the stability of the first adjustment column 525, the connecting column 511 and the second adjustment column 512 during the adjustment and movement process.

[0043] See also Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 The clamping assembly 51 includes a connecting column 511 fixedly connected to the right side of the two L-shaped columns 12 and located at the end of the first adjustment column 525 away from the vertical plate 11. The end of the surface of the connecting column 511 away from the first adjustment column 525 is rotatably connected to the second adjustment column 512. The surface of the second adjustment column 512 is matched with a clamping plate 513. The surface of the clamping plate 513 away from the L-shaped column 12 is fixedly connected to the first spring 514. The clamping plate 513 is slidably connected to the first adjustment column 525.

[0044] It should be noted that when both inclined columns 45 enter the spiral steel pipe, the clamping plate 513 contacts the end of the spiral steel pipe away from the vertical plate 11, and as the first adjusting column 525 and the second adjusting column 512 continue to be adjusted and moved, the first spring 514 is gradually compressed, and relative movement occurs between the protrusion 417 and the spiral groove 415, driving the second adjusting column 512 to rotate, and the drying mechanism 414 can dry the inner wall of the spiral steel pipe at multiple angles, thereby ensuring the drying effect before painting, and the compression degree of the first spring 514 gradually increases. The elastic force of the first spring 514 can ensure that the spiral steel pipe is stably clamped and positioned; in the process of the second adjusting column 512 and the rotating column 41 being adjusted and rotated, the third connecting pipe 410 will also be wound around the outside of the second adjusting column 512 as the rotating column 41 rotates, and will gradually untie during the painting process of the nozzle 47, which will not affect the spraying effect.

[0045] See also Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig.10The paint spraying mechanism 4 includes a rotating column 41 fixedly connected to the second adjusting column 512 at one end away from the connecting column 511, a circular groove 42 is symmetrically opened on the surface of the rotating column 41, a T-shaped column 43 is slidably connected to the groove wall of the circular groove 42, one end of the T-shaped column 43 is fixedly connected to the second spring 44, and the other end of the T-shaped column 43 is fixedly connected to an inclined column 45, one of the inclined columns 45 is symmetrically fixedly connected to the surface of a connecting plate 46, one end of the connecting plate 46 away from the inclined column 45 is fixedly connected to a nozzle 47, a first connecting pipe 48 is fixedly connected to the lower part of the nozzle 47, and a second connecting pipe 49 is fixedly connected to the lower end of the first connecting pipe 48, and the second connecting pipe 49 is fixedly connected to the lower end of the second connecting pipe 49. The end away from the first connecting tube 48 is fixedly connected with the third connecting tube 410, and the third connecting tube 410 is sleeved on the outside of the second adjusting column 512. The end of the surface of the third connecting tube 410 away from the second connecting tube 49 is fixedly connected with the clamping plate 513. The end of the third connecting tube 410 away from the second connecting tube 49 is fixedly connected with the fourth connecting tube 411. The end of the fourth connecting tube 411 away from the third connecting tube 410 is fixedly connected with the delivery pump 412. The storage box 413 is fixedly connected to the bottom plate 1. The end of another connecting plate 46 away from the inclined column 45 is fixedly connected with the drying mechanism 414.

[0046] It should be noted that the surface where the inclined column 45 contacts the inner wall of the spiral steel pipe may be equipped with a plurality of balls to reduce friction resistance and ensure smooth painting of the inner wall of the spiral steel pipe;

[0047] It should be noted that when both inclined columns 45 enter the spiral steel pipe, due to the setting of the friction block 36, the reaction force generated by the compression of the support spring 33 is mostly offset by the friction between the friction block 36 and the L-shaped column 12. When the clamping plate 513 contacts the surface of the end of the spiral steel pipe away from the vertical plate 11, as the second adjusting column 512 continues to move, the first spring 514 is gradually compressed, and the clamping plate 513 clamps the spiral steel pipe to position it. The positioning column 35 and the spiral steel pipe can be maintained at the position when they are clamped and positioned. Relative movement occurs between the clamping plate 513 and the second adjusting column 512, and the convex block 417 cooperates with the spiral groove 415 to drive the rotating column 41 to rotate, and the paint is transported by the delivery pump 412, and the paint passes through the fourth connecting pipe 411, the third connecting pipe 410, and the second connecting pipe 411. The nozzle 47 is connected to the pipe 49 and the first connecting pipe 48 for multi-angle spraying, and the drying mechanism 414 is used for drying. Since the nozzle 47 and the drying mechanism 414 are connected to one of the inclined columns 45 through the connecting plate 46, and the second spring 44 is in a compressed state, the spiral steel pipe is also clamped and positioned. During the rotation of the rotating column 41 and the second adjusting column 512, the distance between the nozzle 47 and the drying mechanism 414 and the inner wall of the spiral steel pipe will not change. That is, according to actual needs, when replacing spiral steel pipes of different diameters for inner wall spraying, the distance between the drying mechanism 414 and the nozzle 47 and the inner wall of the spiral steel pipe is fixed, and there is no need to adjust the spraying distance every time it is replaced, so as to ensure the quality of the paint spraying, save adjustment time, and make the spraying process more efficient.

[0048] It should be noted that the first connecting pipe 48 is a corrugated pipe; the fourth connecting pipe 411 is a hose;

[0049] A spiral groove 415 is formed on the surface of the second adjustment column 512, a round hole 416 is formed on the surface of the clamping plate 513, a protrusion 417 is fixedly connected to the hole wall of the round hole 416, and the spiral groove 415 and the protrusion 417 are installed in coordination;

[0050] It should be noted that when the connecting column 511, the first adjustment column 525 and the second adjustment column 512 are adjusted to move toward the direction close to the vertical plate 11, the clamping plate 513 will be in close contact with the end surface of the spiral steel pipe away from the vertical plate 11, the first spring 514 is gradually compressed, and relative movement occurs between the protrusion 417 and the spiral groove 415, which can drive the second adjustment column 512 to rotate, and the nozzle 47 rotates with the rotation of the second adjustment column 512, and the delivery is carried out by the delivery pump 412 to perform multi-angle spraying.

[0051] The initial state of the second spring 44 is a compressed state;

[0052] It should be noted that the reaction force generated by the compression of the second spring 44 acts on the surface of the T-shaped column 43, so that the inclined column 45 fits tightly against the inner wall of the spiral steel pipe, which can ensure the stability of the nozzle 47 and the drying mechanism 414 during the adjustment and rotation of the rotating column 41, thereby ensuring the quality of painting.

[0053] It should be noted that the drying mechanism 414 is an existing drying device for spraying paint, which includes components such as an electric heater, a fan or blower, a temperature sensor and a humidity sensor. It is an existing mature technology and will not be described in detail here. A controller can be installed on the upper surface of the base plate 1 next to the first motor 524. The drying mechanism 414, the first motor 524 and the delivery pump 412 are all electrically connected to the controller, and the controller is controlled by a computer.

[0054] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
