Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to an on-line temperature measuring device for thermal spraying on the inner wall of a pipeline. Background Technique

[0002] Thermal spraying on the inner wall of a pipeline is a technology that uses a heat source to heat the spraying material to a molten or semi-molten state and spray and deposit it on the surface of the inner wall of the pretreated pipeline at a certain speed to form a coating, which can endow the inner wall of the pipeline with multiple functions such as anti-corrosion, wear resistance, and insulation, so as to achieve the purpose of saving materials and energy.

[0003] At present, the inner wall of the pipeline mainly conducts spraying operations through a sprayer. However, when the sprayer sprays out overheated paint, it is easy to cause local overheating of the pipe wall and the coating, thereby affecting the adhesion and uniformity of the coating, resulting in problems such as a decline in the material properties of the inner wall of the pipeline or peeling of the coating.

[0004] The reason for this problem is that currently, the sprayer is mainly driven to slide on the inner wall of the pipeline for spraying operations. Since the original paint will be preheated during the spraying process of the sprayer, when the overheated paint is sprayed out by the sprayer, it is easy to cause local overheating of the pipe wall and the coating, thereby affecting the adhesion and uniformity of the coating, resulting in a decline in the material properties of the inner wall of the pipeline or peeling of the coating. In view of the deficiencies of the existing technology, we propose an on-line temperature measuring device for thermal spraying on the inner wall of a pipeline to solve the above problems.

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] By providing an on-line temperature measuring device for thermal spraying on the inner wall of a pipeline in an embodiment of the present application, the problem that the inner wall of the pipeline is mainly sprayed by a spraying device, and the overheated coating sprayed by the spraying device is likely to cause local overheating of the pipe wall and the coating, thereby affecting the adhesion and uniformity of the coating and causing a decline in the material performance of the inner wall of the pipeline or peeling of the coating is solved.

[0026] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation modes.

[0027] An embodiment of the present utility model discloses an on-line temperature measuring device for thermal spraying on the inner wall of a pipeline.

[0028] According to the attached Figures 1-5 As shown, an on-line temperature measuring device for thermal spraying on the inner wall of a pipeline includes a temperature detector 1. A bottom of the temperature detector 1 is provided with an assembly mechanism 2. The assembly mechanism 2 is installed at a tail of a spraying device;

[0029] The assembly mechanism 2 includes an assembly table 21, a movable plate 22, a limiting plate 24, and a convex strip 27;

[0030] The assembly table 21 is rotatably connected to the outer peripheral wall of the sprayer. The assembly table 21 is used to rotate the temperature detector 1. The movable plate 22 is movably inserted into the top of the assembly table 21. The convex strip 27 is fixedly connected to the bottom of the temperature detector 1. The convex strip 27 is slidably connected to the top of the movable plate 22. The limiting plate 24 is slidably connected to the inside of the movable plate 22. The limiting plate 24 is clamped at the end of the convex strip 27. The limiting plate 24 is used to fix the temperature detector 1.

[0031] A chute 221 is formed in the top of the movable plate 22. The convex strip 27 is slidably connected to the inside of the chute 221.

[0032] The limiting plate 24 penetrates through the side wall of the chute 221. A dial 242 is fixedly connected to the end side of the limiting plate 24. The dial 242 is slidably connected to the side wall of the movable plate 22. By pinching the two dials 242, the two limiting plates 24 can be driven to contract inside the movable plate 22. At this time, the temperature detector 1 can be disassembled and assembled in the chute 221 at the top of the movable plate 22.

[0033] A spring 241 is fixedly connected to the end of the limiting plate 24. The end of the spring 241 is fixedly connected to the inside of the movable plate 22. The spring 241 is used to reset the limiting plate 24. After releasing the dial 242, the limiting plate 24 and the dial 242 can be reset by the elastic force of the spring 241. At this time, the limiting plate 24 will penetrate through the chute 221 accordingly to fix the temperature detector 1.

[0034] The assembly mechanism 2 further includes an electric telescopic rod 23 and a gear 25;

[0035] The electric telescopic rod 23 is fixedly connected to the top of the assembly table 21. The gear 25 is rotatably connected to the inside of the sprayer. A driving member such as a motor is provided inside the sprayer, and the output shaft of the motor is connected to the gear 25. The gear 25 can be driven to rotate by the motor.

[0036] The end of the electric telescopic rod 23 is fixedly connected to the bottom of the movable plate 22. The electric telescopic rod 23 is used to move the movable plate 22. The movable plate 22 can be driven to lift by the drive of the electric telescopic rod 23, which is convenient for adjustment according to pipes of different sizes. The temperature detector 1 on the movable plate 22 can be made to approach the inner wall of the pipe, which is convenient for measuring the temperature of the paint sprayed on the inner wall of the pipe. The detected data will be imported into the computer in real time for recording.

[0037] An internal tooth groove 26 is formed in the inner wall of the assembly table 21. The internal tooth groove 26 meshes with the gear 25. The gear 25 is used to rotate the assembly table 21. The assembly table 21 can be driven to rotate by the gear 25. At the same time, the assembly table 21 can drive the temperature detector 1 to rotate, which is convenient for measuring the temperature inside the pipe in all directions and improves the comprehensiveness of the detected data.

[0038] The specific functions of the temperature detector 1 can refer to the wireless intelligent online temperature detection device with the model number DWWK.

[0039] When the utility model is in use, first, by pinching two groups of paddles 242, two groups of limiting plates 24 can be driven to contract inside the movable plate 22. At this time, the convex strip 27 on the temperature detector 1 can be inserted into the sliding groove 221 at the top of the movable plate 22. Then, release the paddle 242, and the elastic force of the spring 241 can reset the limiting plate 24 and the paddle 242. At this time, the limiting plate 24 will penetrate through the sliding groove 221 accordingly to fix the temperature detector 1. Secondly, the spraying device can be placed on the inner wall of the pipeline for support, and then the movable plate 22 is driven to move upward by the electric telescopic rod 23 until the temperature detector 1 is close to the inner wall of the pipeline. Finally, drive the spraying device to perform spraying operation on the inner wall of the pipeline. At the same time, the motor can drive the gear 25 to rotate, and through the gear 25, the assembly table 21 and the temperature detector 1 can be driven to rotate, and the temperature detector 1 can then perform real-time temperature measurement on the coating after spraying on the inner wall of the pipeline.
