Description

Technical Field

[0002] In the field of pipeline maintenance, when it is necessary to replace the anti-corrosion lining of a pipeline, the lining usually needs to be softened to facilitate removal. Traditional methods often involve using a spray gun to heat and soften the lining inside the pipeline. However, it is difficult to precisely control the temperature and heating area of ​​the spray gun, which can easily lead to local overheating or uneven heating of the pipeline. This not only affects the softening effect of the lining but may also damage the pipeline itself. The spray gun has low heating efficiency and is cumbersome to operate, requiring frequent manual adjustments to the position and angle of the spray gun.

[0003] To address the aforementioned problems, this invention provides a pipe corrosion-resistant lining softening device. It uses a heating element to soften the lining from the inside of the pipe, and simultaneously controls the pipe rotation via a servo motor during the heating process to achieve uniform heating, effectively avoiding localized overheating. This provides convenient conditions for the next step of removing the lining, significantly improving the efficiency and quality of lining removal. Utility Model Content

[0047] In a preferred embodiment, the heating component 6 includes a heating tube 601, which is arranged at the center of the first pad 404 and the second pad 503. The heating component 6 is mounted on the third bracket 5.

[0048] The second bracket 4 is installed close to the pipe, and the third bracket 5 is used to control the forward and backward movement of the heating element 601.

[0049] A pipe corrosion-resistant lining softening device is used as follows: When using this pipe corrosion-resistant lining softening device, firstly, select the first pad 404 and the second pad 503 according to the pipe specifications, find the heating tube 601 with the corresponding outer diameter, and install the second pressure plate 504 to initially fix the heating tube. After this accessory is installed, move the first bracket 3 to the side close to the fixed bracket 2, and use a hoisting device to place the pipe to be softened into the device. Pass the pipe through the first through hole 204 on the fixing ring 201 of the fixed bracket 2 and the second through hole 307 on the first bracket 3. Then, firstly tighten the first bolt 207 and the second bolt 306 below the pipe, adjust the first clamping block 206 and the second clamping block 304, observe the scale lines on the side of the first clamping block 206 and the second clamping block 304, and place a level on the top of the pipe to adjust it so that the pipe is horizontal and located at the center.

[0050] After the pipeline adjustment is completed, tighten the second bolts 306 in other positions to adjust the position of the second clamping block 304 on the second guide rail 303 to clamp the pipeline. Manually operate the hoisting device to pull the first bracket 3 so that the other end of the pipeline is flush with the fixed bracket 2. Then tighten the first bolts 207 in other positions to adjust the position of the first clamping block 206 on the first guide rail 205 to clamp the pipe and complete the pipeline fixing.

[0051] After the pipe is fixed, move the heating element 601 on the third bracket 5 so that the heating element 601 is fully inserted into the pipe. Note that it should be kept concentric during the insertion process. After the heating element 601 is moved into place, install the first pressure plate 403 to completely fix the heating element 601.

[0052] After the heating element 601 is fixed, the servo motor 203 is started. The drive gear 208 at the output shaft end of the servo motor 203 meshes with the outer circle of the first rotating ring 202. The servo motor 203 drives the drive gear 208 to rotate, thereby driving the first rotating ring 202 to rotate. Since the first through hole 204 is located at the center of the first rotating ring 202, the pipe fixed in the first through hole 204 will also rotate. When the pipe starts to rotate under the drive of the fixed bracket 2, the heating element 601 of the heating assembly 6 is started, and the heating element 601 begins to heat the anti-corrosion lining of the pipe. Because the pipe is rotating, a more uniform heating effect is achieved, effectively improving the quality and efficiency of lining softening.

[0053] Once the liner has softened to a standard removable state, stop the servo motor and use external tools to remove the liner from the pipe. During the removal process, adjust the temperature as needed to facilitate the removal of the pipe liner.
