Description
Technical Field
[0001] This utility model relates to the field of spraying equipment technology, specifically to a spraying device for anti-corrosion coating in anti-corrosion pipe processing. Background Technology
[0002] Due to the inherent properties of steel pipes, those without any anti-corrosion treatment will have a very short lifespan under normal use. Therefore, steel pipes manufactured today undergo general anti-corrosion treatment unless otherwise specified.
[0003] Currently, the spraying process for anti-corrosion pipelines is usually carried out manually using handheld spray guns. However, this method, which relies on touch, has limited precision and cannot accurately control the thickness of the coating on both the inside and outside of the pipeline. Furthermore, the spraying of the inner walls of some large-diameter anti-corrosion pipelines often requires manual entry, which is a confined space operation. This method is difficult and dangerous for personnel, inefficient, and unsuitable for steel pipes whose inner diameter does not meet the requirements for personnel entry, thus having significant limitations. Utility Model Content
[0004] To address the aforementioned technical problems, an anti-corrosion coating spraying device for anti-corrosion pipe processing is provided. This technical solution solves the problems mentioned in the background art, where the current anti-corrosion pipe spraying process is usually carried out manually using a handheld spray gun. However, the accuracy of manual handheld spray gun spraying, which relies on feel, is limited, and the thickness of the coating on the inside and outside of the anti-corrosion pipe cannot be precisely controlled. At the same time, the spraying of the inner wall of some large-diameter anti-corrosion pipes often requires manual entry. This method is a confined space operation, which is difficult for personnel to operate and has certain dangers. It is also inefficient and not suitable for steel pipes whose inner diameter does not meet the requirements for personnel entry, thus having significant limitations.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A corrosion-resistant coating spraying device for processing corrosion-resistant pipes includes a base plate, a lifting cylinder is provided at the top of the base plate, a corrosion-resistant pipe body is provided at the top of the lifting cylinder, an inner wall spraying mechanism is provided inside the corrosion-resistant pipe body, a gantry frame is provided at the top of the base plate, a second lead screw is provided inside the gantry frame, and an outer wall spraying mechanism is provided at the bottom of the gantry frame. The inner wall spraying mechanism includes a mounting frame, inside which a first fixing rod is fixedly installed. A first lead screw is rotatably installed on the left side of the first fixing rod. A fixing member is provided on the outer right side of the first fixing rod. A first connecting rod is rotatably installed on the inner side of the fixing member. Three sets of the first connecting rods are arranged in a circumferential array. The other ends of the three sets of the first connecting rods are rotatably installed on the bottom end of the movable block. The three sets of the movable blocks are movably installed in the movable groove opened at the bottom end of the movable plate.
[0006] Preferably, a movable block is threadedly connected to the outer surface of the first lead screw, and a second connecting rod is rotatably mounted on the inner side of the movable block. Three sets of the second connecting rods are arranged in a circumferential array, and the other ends of the three sets of second connecting rods are rotatably mounted on the bottom end of the movable plate.
[0007] Preferably, each of the three sets of movable plates has two sets of movable wheels on its outer side, and each of the three sets of movable wheels has a driven bevel gear on one side. Each of the three sets of movable plates has a second motor on its rear side, and each of the three sets of second motors has a driving bevel gear fixedly installed at its output end. Each of the three sets of driving bevel gears meshes with the driven bevel gear.
[0008] Preferably, a spray head is provided on the right side of the mounting bracket, and a first spray nozzle is connected to the right side of the spray head. Several sets of spray heads are arranged in a circular array on the outer side of the spray head.
[0009] Preferably, a first motor is provided on the left side of the mounting bracket, and the output end of the first motor is fixedly installed on the left side of the first lead screw.
[0010] Preferably, the lifting cylinder is provided in two sets, and an arc-shaped bracket is fixedly installed at the top of each set of lifting cylinders. The two sets of arc-shaped brackets are respectively located at the bottom of the left and right sides of the anti-corrosion pipe body.
[0011] Preferably, the top of the gantry frame is provided with a slot, and a second lead screw is rotatably installed inside the slot. One end of the second lead screw is fixedly installed at the output end of the third motor. A slider is threadedly connected to the outer surface of the second lead screw, and an outer wall spraying mechanism is provided at the bottom end of the slider.
[0012] Preferably, the outer wall spraying mechanism includes an upper spraying component and a lower spraying component. The lower spraying component is rotatably mounted on one end of the upper spraying component via a rotating component. The upper and lower spraying components are connected by a flexible hose. An upper clamping plate is provided at the other end of the upper spraying component. A clamping groove is formed on the outer surface of the top of the upper clamping plate. A lower clamping plate is provided at the bottom end of the lower spraying component. A second fixing rod is rotatably mounted at the bottom end of the lower clamping plate. A clamping block is fixedly mounted on the top of the second fixing rod via a movable component. A second spraying pipe is provided on the front side of the upper spraying component. Spray heads are provided on the inner walls of both the upper and lower spraying components.
[0013] Compared with the prior art, the beneficial effects of this utility model are: First, by setting up an inner wall spraying mechanism, a first motor drives a first lead screw to rotate, causing a moving block to move. This, in turn, drives a movable plate to move via a second connecting rod. Simultaneously, the rotation of a first fixed rod drives the first connecting rod, causing the movable block to move within a movable groove. This allows the movable wheel on the outer side of the movable plate to fit against the inner wall of the pipe. The second motor then drives a driving bevel gear to mesh with a driven bevel gear, causing the movable wheel to rotate. This facilitates the movement of the inner wall spraying mechanism within the pipe. The inner wall is then sprayed via a first spraying connector and a spray head. No manual entry into the pipe is required, avoiding the dangers of confined space operations and improving operational safety. Second, by setting up an outer wall spraying mechanism, a third motor drives a second lead screw to rotate, causing a slider to move. This, in turn, moves the outer wall spraying mechanism. The upper and lower spraying components open and close via rotating parts and locking blocks, facilitating the spraying of the outer wall of the anti-corrosion pipe. This achieves automated spraying of the outer wall of the anti-corrosion pipe, eliminating the need for manual hand-held spray guns and improving spraying efficiency and accuracy.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0017] Reference Figure 1-5 As shown, an anti-corrosion coating spraying device for processing anti-corrosion pipes includes a base plate 1. A lifting cylinder 2 is provided at the top of the base plate 1. An anti-corrosion pipe body 3 is provided at the top of the lifting cylinder 2. There are two sets of lifting cylinders 2. An arc-shaped bracket 201 is fixedly installed at the top of each set of lifting cylinders 2. The two sets of arc-shaped brackets 201 are respectively provided at the bottom of the left and right sides of the anti-corrosion pipe body 3. An inner wall spraying mechanism 4 is provided inside the anti-corrosion pipe body 3. A gantry frame 5 is provided at the top of the base plate 1. A second lead screw 6 is provided inside the gantry frame 5. An outer wall spraying mechanism 7 is provided at the bottom of the gantry frame 5.
[0018] In this scheme, the synchronous extension and retraction adjustment of two sets of lifting cylinders 2 achieves precise positioning of the anti-corrosion pipe body 3 in the vertical direction, which is convenient for matching the spraying operation requirements of different pipe diameters. Secondly, by setting the curved support structure with arc bracket 201, the contact area is increased, which effectively reduces the risk of shaking of the anti-corrosion pipe body 3 during the spraying process. Furthermore, by setting the second lead screw 6 inside the gantry 5, the outer wall spraying mechanism 7 is stably suspended above the anti-corrosion pipe body 3, ensuring the continuity of the spraying operation. Moreover, by driving the outer wall spraying mechanism 7 along the axial direction of the anti-corrosion pipe body 3 through the thread drive, a uniform coverage effect of the outer wall coating is achieved.
[0019] Reference Figure 2-3As shown, the inner wall spraying mechanism 4 includes a mounting frame 401. A spray head 416 is provided on the right side of the mounting frame 401. A first spraying pipe 417 is connected to the right side of the spray head 416. Several sets of spray heads are arranged in a circular array on the outer side of the spray head 416. A first fixing rod 402 is fixedly installed inside the mounting frame 401. A first lead screw 404 is rotatably installed on the left side of the first fixing rod 402. A first motor 403 is provided on the left side of the mounting frame 401. The output end of the first motor 403 is fixedly installed on the left side of the first lead screw 404. A fixing member 405 is provided on the outer surface of the right side of the first fixing rod 402. A first connecting rod 406 is rotatably installed on the inner side of the fixing member 405. Three sets of first connecting rods 406 are arranged in a circular array. The other ends of the three sets of first connecting rods 406 are rotatably installed on the bottom end of the movable block 407. The three sets of movable blocks 407 are movably installed in the movable groove 409 opened at the bottom end of the movable plate 408.
[0020] In this scheme, the first motor 403 drives the first lead screw 404 to rotate, realizing the linear displacement of the moving block 410. Then, the second connecting rod 411 drives the movable plate 408 to expand radially. The axial displacement of the moving block 410 drives the second connecting rod 411 to move synchronously, realizing the rapid adaptation of the spray head 416 to the inner wall of different pipe diameters, ensuring that the spray head assembly maintains a constant distance from the inner wall.
[0021] Reference Figure 2-3 As shown, a movable block 410 is threadedly connected to the outer surface of the first lead screw 404. A second connecting rod 411 is rotatably mounted on the inner side of the movable block 410. Three sets of the second connecting rods 411 are arranged in a circumferential array. The other ends of the three sets of second connecting rods 411 are rotatably mounted on the bottom end of the movable plate 408. Two sets of movable wheels 412 are provided on the outer side of each of the three sets of movable plates 408. A driven bevel gear 413 is provided on one side of each of the three sets of movable wheels 412. A second motor 414 is provided on the rear side of each of the three sets of movable plates 408. A driving bevel gear 415 is fixedly mounted on the output end of each of the three sets of second motors 414. The three sets of driving bevel gears 415 mesh with the driven bevel gears 413 respectively.
[0022] In this scheme, the second motor 414 drives the active bevel gear 415 to rotate and mesh with the driven bevel gear 413 to rotate, thereby realizing the autonomous feeding of the movable wheel 412 to the inner wall of the anti-corrosion pipe body 3, avoiding the instability of manual pushing. At the same time, in coordination with the first spraying pipe 417 and the spraying head 416, the uniform coverage of the anti-corrosion coating on the inner wall is ensured.
[0023] Reference Figure 1As shown, the top of the gantry frame 5 has a slot 501, and a second lead screw 6 is rotatably installed inside the slot 501. One end of the second lead screw 6 is fixedly installed at the output end of the third motor 601. A slider 602 is threadedly connected to the outer surface of the second lead screw 6, and an outer wall spraying mechanism 7 is provided at the bottom end of the slider 602.
[0024] The third motor 601 drives the second lead screw 6 to rotate, which in turn drives the slider 602 to move precisely along the slot 501. This achieves precise axial positioning of the outer wall spraying mechanism 7, ensuring that the spraying trajectory matches the outer wall of the workpiece. Through the rigid connection between the slider 602 and the outer wall spraying mechanism 7, and the transmission of the second lead screw 6, the smooth movement of the spraying mechanism is achieved, ensuring the uniformity of the coating. The slot 501 at the top of the gantry 5 guides and constrains the movement path of the slider 602, preventing deviation during the operation of the mechanism. This achieves stable linear operation of the outer wall spraying mechanism 7, and automatically maintains its current position when the third motor 601 stops, thus achieving fixed-point hovering of the outer wall spraying mechanism 7.
[0025] Reference Figure 4-5 As shown, the outer wall spraying mechanism 7 includes an upper spraying component 701 and a lower spraying component 702. The lower spraying component 702 is rotatably mounted on one end of the upper spraying component 701 via a rotating component. The connection between the upper spraying component 701 and the lower spraying component 702 is connected by a hose 703. An upper clamping plate 704 is provided at the other end of the upper spraying component 701. A clamping groove 705 is provided on the outer surface of the top of the upper clamping plate 704. A lower clamping plate 706 is provided at the bottom end of the lower spraying component 702. A second fixing rod 707 is rotatably mounted at the bottom end of the lower clamping plate 706. A clamping block 708 is fixedly mounted on the top of the second fixing rod 707 via a movable component. A second spraying pipe 709 is provided on the front side of the upper spraying component 701. Spray heads are provided on the inner walls of both the upper spraying component 701 and the lower spraying component 702.
[0026] In this solution, the hinged structure of the upper spraying component 701 and the lower spraying component 702, combined with the flexible connection of the hose 703, enables the spraying mechanism to adaptively fit complex curved surfaces, ensuring that the spray head maintains the optimal spraying distance to the outer wall of the workpiece. Secondly, a quick-locking mechanism with a locking block 708 and a locking groove 705 is provided. The upper locking plate 704 and the lower locking plate 706 are rigidly fixed by the lever action of the second fixing rod 707, achieving a quick-locking function. Furthermore, the second spraying pipe 709 simultaneously supplies material to the upper and lower spray heads, and with the guiding effect of the hose 703, the paint is evenly distributed in the upper spraying component 701 and the lower spraying component 702. By setting up a multi-point distributed spray head array and optimizing the spraying angle and coverage, the outer wall coating is formed in one step, reducing the need for repeated spraying processes.
[0027] The working principle of this utility model is as follows: First, the lifting cylinder 2 pushes the arc-shaped bracket 201 to move vertically, adjusting the height of the anti-corrosion pipe body 3. The arc-shaped bracket 201 supports the anti-corrosion pipe body 3 through its curved surface, reducing swaying. Second, the first motor 403 drives the first lead screw 404 to rotate, causing the moving block 410 to move axially. The second connecting rod 411 pushes the movable plate 408 to expand radially, causing the movable wheel 412 to contact the inner wall of the anti-corrosion pipe body 3. The second motor 414 drives the driven bevel gear 413 to rotate through the active bevel gear 415, driving the movable wheel 412 to move along the inner wall. The spray head 416 receives the coating through the first spray nozzle 417. The nozzle sprays the inner wall. Furthermore, the second lead screw 6 is driven to rotate by the third motor 601, which drives the slider 602 to move along the slot 501. The locking block 708 is embedded in the locking slot 705 to lock the upper locking plate 704 and the lower locking plate 706. The second spraying pipe 709 delivers paint to the spray head. The outer wall spraying mechanism 7 moves axially with the slider 602. The upper spraying component 701 and the lower spraying component 702 spray paint through the spray head. The hose 703 connects the upper spraying component 701 and the lower spraying component 702. The inner wall spraying mechanism 4 and the outer wall spraying mechanism 7 operate synchronously to complete the synchronous spraying of the inner and outer walls of the anti-corrosion pipe body 3, thereby reducing the processing time of the anti-corrosion pipe body 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
