Description

Technical Field

[0001] The utility model relates to the technical field of pipeline inner wall spraying, in particular to a pipeline inner wall spraying device with an adjustable support range. Background Art

[0002] Background technology: In industrial and civil pipeline applications, the use of inner wall coatings enhances the corrosion resistance of pipelines and prolongs their service life. Pipeline inner wall spraying is usually intended to provide corrosion protection, wear protection, and chemical reaction isolation, thereby ensuring the purity of the transported medium and the safety of the pipeline.

[0003] However, in the prior art, the inner wall spraying operation of large pipelines often requires workers to directly enter the pipeline to perform hand-held spraying, which has multiple inconveniences and risks. First, the narrow operating space limits the operating efficiency, and workers are exposed to potentially harmful chemicals for a long time, making it difficult to maintain a safe distance, increasing health risks. In addition, when traditional hand-held spraying equipment is used to handle small-diameter pipelines, it is difficult to evenly apply the spray material due to the small space and difficult operation, which often leads to problems such as uneven coating thickness and incomplete coverage, affecting the final spraying quality and protective effect.

[0004] Therefore, for the inner wall spraying operations of large and small diameter pipes, it is urgent to develop a new type of equipment that is more efficient, safe and can ensure spraying uniformity. Utility Model Content

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1-Figure 4 As shown, the utility model provides a pipe inner wall spraying device with an adjustable support range: comprising a fixed plate 1 and a connecting plate 2, an adjusting mechanism is arranged between the fixed plate 1 and the connecting plate 2, and the adjusting mechanism is used to drive the moving end to move according to different pipe diameters;

[0032] A spraying mechanism is provided on one side of the fixed plate 1, and the spraying mechanism realizes spraying on the inner wall of the pipeline by rotating multiple spraying ends;

[0033] The adjusting mechanism comprises a bidirectional screw rod 3, a rotating ring 4, a sleeve 5, a sliding rod 6 and a moving nut 7. The bidirectional screw rod 3 is rotatably connected between the fixed plate 1 and the connecting plate 2. The rotating ring 4 is rotatably connected to the middle of the bidirectional screw rod 3. The sleeve 5 is equidistantly fixedly connected to the outside of the rotating ring 4. The sliding rod 6 is slidably connected to the inside of the corresponding sleeve 5. The moving nut 7 is symmetrically threadedly connected to the outside of the bidirectional screw rod 3.

[0034] In summary: the rotation of the bidirectional screw rod 3 can drive the two movable nuts 7 to move, so that the two movable nuts 7 are moved closer to or farther away from each other.

[0035] like Figure 1-Figure 4As shown, the adjustment mechanism also includes a fixed block 9, a roller 10, a connecting rod 11 and a light rod 12, the fixed block 9 is fixedly connected to the corresponding sliding rod 6, the outer side of the moving nut 7 is equidistantly fixedly connected with a connecting ear 8, the roller 10 is rotatably connected to the corresponding fixed block 9, the connecting rod 11 is rotatably connected between the corresponding fixed block 9 and the corresponding two connecting ears 8, the fixed plate 1 and the connecting plate 2 are equidistantly fixedly connected with the light rod 12, the light rod 12 is fixedly connected to the rotating ring 4, and the light rod 12 is slidably connected to the corresponding moving nut 7;

[0036] In summary: when the two movable nuts 7 approach each other, the connecting rod 11 will drive the sliding rod 6 to rise, so that the roller 10 will rise, thereby increasing the diameter range between the multiple rollers 10, and vice versa, it will become smaller, so as to adapt to pipes of different diameters.

[0037] like Figure 1-Figure 4 As shown, the spraying mechanism includes an adjusting arc plate 13, an arc rod 14, a moving block 15, and a spring 16. The adjusting arc plate 13 is fixedly connected to one side of the fixed plate 1 at equal distances. The adjusting arc plate 13 is set to a hollow structure. The arc rod 14 is fixedly connected to the inside of the corresponding adjusting arc plate 13. The moving block 15 is slidably connected to the outside of the corresponding arc rod 14. The moving blocks 15 are all slidably connected to the corresponding adjusting arc plate 13. The spring 16 is sleeved on the outside of the arc rod 14 and is located between the corresponding adjusting arc plate 13 and the moving block 15.

[0038] In summary, the moving block 15 will compress the spring 16 when moving, and then the elastic force of the spring 16 will rebound the moving block 15 .

[0039] like Figure 1-Figure 4 As shown, the spraying mechanism also includes a spray head 17, a contact block 18, an arc groove 19 and a limit rod 20. The spray head 17 is fixedly connected to the corresponding moving block 15, and the spray head 17 is connected to an external spray material supply device. The contact block 18 is slidably connected to the bottom of the moving block 15. Arc grooves 19 are equidistantly provided on the fixed plate 1 and inside the adjusting arc plate 13. The limit rod 20 is fixedly connected to one side of the corresponding contact block 18, and the limit rod 20 extends to the inside of the corresponding arc groove 19 and is slidably connected thereto.

[0040] In summary: the nozzle 17 is a fan-shaped structure. This structure of the nozzle 17 is an existing mature technology. By limiting the type of the nozzle 17, it can be ensured that the device can perform spraying without dead angles. When the moving block 15 moves, it can drive the contact block 18 to move. The contact block 18 can move toward the moving block 15, and the arc groove 19 is high at one end and low at the other end. In this way, the contact block 18 will rise and fall when following the movement of the moving block 15.

[0041] like Figure 1-Figure 4As shown, the spraying mechanism also includes a gear ring 21, a collision block 22 and a gear 23.

The gear 23 is arranged inside the gear ring 21, and the gear 23 is meshed and connected with the gear ring 21;

[0042] In summary: when the ring gear 21 rotates, it drives the collision block 22 to contact the contact block 18 and drive it to move. After the contact block 18 moves to the preset position, its height is staggered with the collision block 22, and then the collision block 22 and the contact block 18 are reset by the spring 16 to facilitate the next contact.

[0043] like Figure 1-Figure 4 As shown, a fixing frame 24 is fixedly connected to the fixing plate 1, a driving shaft 25 is rotatably connected inside the fixing frame 24, one end of the driving shaft 25 extends to the other side of the fixing plate 1 and is fixedly connected to the bidirectional screw rod 3, one end of the driving shaft 25 is fixedly connected to a turntable 26, a driving motor 27 is fixedly connected to the fixing frame 24, and an output end of the driving motor 27 is fixedly connected to the gear 23;

[0044] In summary: the fixing frame 24 is a cross structure, which is convenient for users to grasp and fix, and the bidirectional screw rod 3 can be driven to rotate by rotating the turntable 26, and the driving motor 27 can drive the gear 23 to rotate, thereby driving the gear ring 21 to rotate through the engagement of the gear 23 and the gear ring 21.

[0045] Working principle:

[0046] In actual use, the device is placed in a pipeline, and then the bidirectional screw rod 3 is driven to rotate by rotating the turntable 26. The bidirectional screw rod 3 can drive the two moving nuts 7 to move when rotating, so that the two moving nuts 7 are close to or away from each other. When the two moving nuts 7 are close to each other, the sliding rod 6 will be driven to rise through the connecting rod 11, so that the roller 10 will rise until the roller 10 contacts the pipe wall, that is, the adjustment work is completed, and then the driving motor 27 is started. The driving motor 27 can drive the gear 23 to rotate. When the ring gear 21 rotates, it drives the collision block 22 to contact the contact block 18 and drives it to move. One end of the arc groove 19 is high and the other end is low. In this way, the contact block 18 will rise and fall when following the movement of the moving block 15, so that after the contact block 18 moves to the preset position, its height is staggered with the collision block 22, and then the collision block 22 and the contact block 18 are reset by the spring 16 so that they can contact next time, so that the inner wall of the pipeline can be sprayed without dead angles.
