Description

Technical Field

[0001] This utility model belongs to the field of pipe spraying technology, specifically, it relates to a pipe spraying device. Background Technology

[0002] Internal pipe coating is a technology used to prevent corrosion of the inner wall of metal pipes and improve transportation efficiency. It uses different spraying methods and coatings to evenly apply a coating to the inner wall of the pipe, forming a smooth, corrosion-resistant, and friction-reducing protective layer. Without internal corrosion protection, corrosion will occur, leading to premature scrapping.

[0003] 1. Existing equipment often uses multiple metal plates to fix metal pipes, which can lead to insecure fixing and the metal pipes rolling off, causing accidents.

[0004] 2: Most existing equipment involves manual spraying of the inner wall of pipes using a spray gun, which may result in uneven coating and consumes a lot of labor, leading to low work efficiency. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues of weak fixation and excessive time required for spraying mentioned above, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide an in-pipe spraying device. This device uses a second motor to drive a rotating rod to rotate. Due to the presence of positive and negative threads on the rotating rod, the rotation drives the clamping plate to move inwards and outwards. A clamp on the clamping plate effectively fixes the steel pipe to the base. The device also uses a third motor to drive a threaded rod to rotate. When the threaded rod rotates, it moves the storage box. A limit block is provided in the storage box. Placing the limit block into the second slot inside the nozzle achieves the effect of the storage box moving and the nozzle rotating. The storage box then pushes the nozzle to move. Because the nozzle has protrusions inside, when the nozzle moves, these protrusions follow the threaded trajectory on the threaded rod. When the nozzle rotates, the nozzle on the nozzle evenly sprays coating onto the inside of the steel pipe.

[0022] 3. Beneficial effects:

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This type of pipe spraying device uses a second motor to drive a rotating rod to rotate. Due to the positive and negative threads on the rotating rod, the rotation of the rotating rod drives the clamping plate to move in the same direction in and out. The clamps on the clamping plate effectively fix the steel pipe to the base.

[0025] This type of in-pipe spraying device uses a third motor to drive a threaded rod to rotate. When the threaded rod rotates, it moves the storage box. The storage box is equipped with a limit block, which is placed in the second slot inside the nozzle. This achieves the effect of moving the storage box and rotating the nozzle. The storage box then pushes the nozzle to move. Because the nozzle has protrusions inside, when the nozzle moves, the protrusions inside the nozzle rotate along the threaded trajectory on the threaded rod. When the nozzle rotates, the nozzle on the nozzle performs a uniform spraying effect on the inside of the steel pipe. Attached Figure Description

[0039] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0040] This utility model provides an overall structural schematic diagram of an embodiment of an in-pipe spraying device, including:

[0041] Reference Figures 1-6 This embodiment of an in-pipe spraying device includes a base 1, a moving component 2, a clamping component 3, a steel pipe 4, a fixing plate 5, a first groove 6, a sliding groove 7, a second groove 8, and a spraying component 9. The moving component 2 is located above the base 1 and to the left of the clamping component 3. The clamping component 3 is located above the base 1 and to the right of the spraying component 9. The spraying component 9 is located above the base 1 and above the moving component 2. The moving component 2 includes a first motor 201, a rotating rod 202, and a moving plate 203. The first motor 201 is fixedly connected to one side of the base 1. The output shaft of the first motor 201 is provided with the rotating rod 202. The moving plate 203 is sleeved on the outer circumferential wall of the rotating rod 202, and the rotating rod 202 and the moving plate 203 are slidably connected.

[0042] It is worth noting that, specifically, to allow the clamping plate 305 to move, the clamping assembly 3 includes a second motor 301, a rotating rod 302, a positive thread 303, a negative thread 304, a clamping plate 305, and a clamp 306. The second motor 301 is fixedly connected to one side of the base 1. The output shaft of the second motor 301 is equipped with the rotating rod 302. The outer circumference of the rotating rod 302 is provided with a positive thread 303, and the outer circumference of the rotating rod 302 is provided with a negative thread 304. The rotation of the second motor 301 drives the rotating rod 302. Since the rotating rod 302 is provided with a positive thread 303 and a negative thread 304, when the rotating rod 302 rotates, it can drive the clamping plate 305 to move in the same direction, both internally and externally.

[0043] Next, to facilitate the fixing of the steel pipe 4 by the clamping plate 305, specifically, the clamping plate 305 is sleeved on the outer circumference of the rotating rod 302, and the clamping plate 305 and the rotating rod 302 are slidably connected. A clamp 306 is fixedly connected to the top side of the clamping plate 305. The rotation of the rotating rod 302 drives the clamping plate 305 to move. When the clamping plate 305 moves, the clamp 306 on the clamping plate 305 clamps and fixes the steel pipe 4.

[0044] Meanwhile, to facilitate the movement of the storage box 903, the spraying assembly 9 specifically includes a third motor 901, a threaded rod 902, a storage box 903, a first slot 904, a limiting block 905, a spray head 906, a second slot 907, a protrusion 908, and a nozzle 909. The third motor 901 is fixedly connected to one side of the moving plate 203. The output shaft of the third motor 901 is provided with the threaded rod 902. The storage box 903 is fitted onto the outer circumference of the threaded rod 902. The first slot 904 is opened inside the storage box 903. The limiting block 905 is fixedly connected to the side of the storage box 903 away from the moving plate 203. Manually starting the third motor 901 rotates the threaded rod 902, which in turn moves the storage box 903 forward.

[0045] Meanwhile, to facilitate the rotation of the nozzle 906, specifically, the nozzle 906 is fixedly connected to the side of the storage box 903 away from the moving plate 203. A second slot 907 is formed inside the nozzle 906, and the second slot 907 is fitted onto the outer circumferential wall of the limiting block 905, with the second slot 907 and the limiting block 905 being rotatably connected. By providing the limiting block 905 on the storage box 903, when the limiting block 905 is placed inside the second slot 907 of the nozzle 906, the nozzle 906 can rotate under the action of the limiting block 905 and the second slot 907.

[0046] Meanwhile, to facilitate the rotation of the spray head 906, specifically, a protrusion 908 is fixedly connected inside the spray head 906, and the protrusion 908 is located within the thread of the threaded rod 902. A nozzle 909 is fixedly connected to the outer circumference of the spray head 906. Because the protrusion 908 is located within the thread of the threaded rod 902, when the threaded rod 902 rotates, it drives the spray head 906 to rotate. The nozzle 909 on the spray head 906 then sprays the inner wall of the steel pipe 4, achieving the desired coating effect.

[0047] Meanwhile, to facilitate the placement of the steel pipe 4 onto the base 1, specifically, a first groove 6 is formed on the top of the base 1, and the rotating rod 202 is located inside the first groove 6. A sliding groove 7 is formed inside the first groove 6, and the sliding groove 7 is fitted onto the bottom of the moving plate 203. A fixing plate 5 is provided on the top of the base 1, and the steel pipe 4 is placed on the top of the fixing plate 5. A second groove 8 is formed on the top of the base 1, and the rotating rod 302 is located inside the second groove 8. The steel pipe 4 is placed onto the base 1 through the fixing plate 5 provided on the base 1.

[0048] The models of the devices or equipment mentioned in this article are as follows:

[0049] The model of the first motor 201 can be: YE3-100;

[0050] The model number of the second motor 301 can be: YE3-59;

[0051] The model number of the third motor 901 can be: YE3-130.

[0052] Combination Figures 1-6 The following is a specific usage process of an in-pipe spraying device according to this embodiment:

[0053] 1. Based on the actual usage, first place the steel pipe 4 on the fixing plate 5 on the base 1, then manually start the second motor 301. The output shaft of the second motor 301 drives the rotating rod 302 to rotate. Since the surface of the rotating rod 302 is provided with positive thread 303 and negative thread 304, when the rotating rod 302 rotates, it can drive the clamping plate 305 to move in the same direction in the same direction under the action of the positive thread 303 and negative thread 304. When the clamping plate 305 moves, it clamps and fixes the steel pipe 4 on the fixing plate 5.

[0054] 2. After the steel pipe 4 is fixed, manually start the first motor 201. The output shaft of the first motor 201 rotates, driving the rotating rod 202 to rotate. When the rotating rod 202 rotates, it drives the moving plate 203 to move. When the moving plate 203 moves, it moves the nozzle 906 into the steel pipe 4. When the nozzle 906 moves into the steel pipe 4, manually start the third motor 901. The output shaft of the third motor 901 drives the threaded rod 902 to rotate. The rotation of the threaded rod 902 moves the storage box 903. When the storage box 903 moves, a limit block 905 is set in the storage box 903. The limit block 905 is placed in the second slot 907 in the nozzle 906, realizing the effect of the storage box 903 moving and the nozzle rotating.

[0055] 3: Then, the nozzle 906 is moved by the storage box 903. Since there is a protrusion 908 inside the nozzle 906, when the nozzle 906 moves, the protrusion 908 inside the nozzle 906 follows the thread track on the threaded rod 902, so that the nozzle 906 rotates and sprays the inside of the steel pipe 4 evenly.

[0056] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
