[0024] Example This embodiment 1 provides a pipe deformation rate detection device, such as Figures 1-4 As shown, the specific structure is described below.
[0025] Combination Figure 1 As shown, the pipeline deformation rate detection device of this utility model mainly includes two parts: a support mechanism 1 and a detection mechanism 2. The support mechanism 1 is used to stably support the pipeline deformation rate detection device, and the detection mechanism 2 is used to detect the degree of deformation of the pipeline.
[0026] Furthermore, in combination Figure 1 As shown, the support mechanism 1 includes a tripod 102 and a base 101. The base 101 is mounted on top of the tripod 102, and a level 10 is also mounted on the base 101. During installation, the tripod 102 is mounted on the bottom of the base 101. Before testing, the length of the tripod legs and the opening angle need to be adjusted according to the actual situation to ensure that the base 101 is in a horizontal state. The horizontal state is monitored by the level 10.
[0027] In this embodiment, combined with Figure 1 , Figure 2 and Figure 3 As shown, the testing mechanism 2 includes a ring track 201 and a moving part 202. The ring track 201 includes two parts: a second semi-ring track 2012 and a first semi-ring track 2011. A rotating adjustment rod 11 is installed at the bottom of the second semi-ring track 2012. The rotating adjustment rod 11 is inserted into the top of the platform 101 and tightened by a Phillips screw.
[0028] Combination Figure 1 and Figure 4As shown, a horizontal second mounting plate 2015 is installed on each of the left and right sides of the second semi-circular track 2012, and a horizontal first mounting plate 2014 is installed on each of the left and right sides of the first semi-circular track 2011. The first mounting plates 2014 and the second mounting plates 2015 are vertically aligned. For easy connection and fixation, the first mounting plate 2014 is fixed with vertically downward-facing studs 8 and guide posts 9. The second mounting plate 2015 has mounting holes corresponding to the studs 8 and positioning holes corresponding to the guide posts 9. After the studs 8 and guide posts 9 are inserted, nuts 801 are screwed onto the studs 8 to achieve a fixed connection between the first semi-circular track 2011 and the second semi-circular track 2012. The guide posts 9 and positioning holes ensure accurate alignment between the first semi-circular track 2011 and the second semi-circular track 2012, reducing alignment deviation.
[0029] In this embodiment, combined with Figure 2 and Figure 3 As shown, the annular track 201 is made of hollow rectangular steel pipe. Inside the annular track 201, there is a cavity with a rectangular cross section. The inner side wall of the annular track 201 is provided with an annular through groove 5. The through groove 5 facilitates the extension of the distance measuring machine 3, which is used to detect the distance between the pipes.
[0030] Furthermore, the movable component 202 is block-shaped and installed inside the chamber of the circular track 201, while the rangefinder 3 is installed on top of the movable component 202.
[0031] To facilitate stable movement of the movable component 202, a sliding ring rail 6 is also installed inside the annular track 201. The sliding ring rail 6 is fixedly connected to the inner wall of the annular track 201 via a connecting rod 601. Figure 2 and Figure 3 As shown, the moving part 202 has a through hole 2021, and the curvature of the through hole 2021 is the same as that of the sliding ring rail 6. Both ends of the through hole 2021 are flared openings 2022.
[0032] The sliding ring rail 6 passes through the through hole 2021 of the moving part 202, and the moving part 202 slides along the sliding ring rail 6. The moving part 202 has a groove that connects to the through hole 2021 to facilitate the insertion of the connecting rod 601.
[0033] It should be noted that lubricant is applied to the surface of the sliding ring rail 6 to ensure smooth sliding. Furthermore, the accuracy of the sliding ring rail 6 is related to the detection accuracy, so the roundness of the sliding ring rail 6 should be as close to 0 as possible.
[0034] In this embodiment, combined with Figure 2 and Figure 3As shown, the drive mechanism 4 comprises three parts: a drive motor 401, a gear 402, and a rack 403. The drive motor 401 is mounted on the bottom of the moving part 202. The gear 402 is mounted on the bottom of the moving part 202 via a support. The output shaft of the drive motor 401 and the transmission shaft of the gear 402 are connected, allowing the drive motor 401 to drive the gear 402 to rotate. The three parts, including the rack 403, are mounted along the annular track 201, and the gear 402 and rack 403 mesh. The drive motor 401 drives the gear 402 to rotate, thereby driving the moving part 202 to move along the second semi-annular track 2012 and the first semi-annular track 2011.
[0035] Furthermore, in combination Figure 2 and Figure 3 As shown, to facilitate power supply to the drive motor 401, two wires 701 are connected to the positive and negative terminals of the drive motor 401, and the two wires 701 are respectively connected to the elastic conductive sheet 7. The elastic conductive sheet 7 is a flexible metal strip, and the elastic conductive sheet 7 is fixedly connected to the top of the moving part 202. Two annular connecting plates are installed on the inner wall of the annular track 201. The annular connecting plate in the second semi-annular track 2012 is connected to an external power source. The elastic conductive sheet 7 and the annular connecting plate abut against each other to supply power to the drive motor 401.
[0036] Furthermore, the inner wall of the annular track 201 is provided with an annular groove 2013, and the annular contact piece is disposed in the annular groove 2013. The elastic conductive piece 7 extends into the annular groove 2013 and connects with the annular contact piece. This better constrains the elastic conductive piece 7 and prevents it from deviating.
[0037] It should be noted that the drive motor 401 can be equipped with its own battery, which can provide power to the drive motor 401 when there is no external power supply. When an external power supply is available, the battery can also be charged by relying on the elastic conductive sheet 7 and the annular contact piece.
[0038] The working principle of the pipeline deformation rate detection device of this utility model is as follows: The pipe deformation rate detection device is installed outside the pipe to be tested. The drive motor 401 is started, causing the gear 402 to rotate. The gear 402 rolls on the rack 403, thereby moving the moving part 202 along the annular track 201. During the movement of the moving part 202, the elastic conductive sheet 7 slides on the annular contact plate, providing a continuous power supply to the drive motor 401. The drive motor 401 is a stepper motor. The controller built into the pipe deformation rate detection device controls the operation of the drive motor 401. By counting the number of rotations of the drive motor 401, its position on the annular track 201 can be determined.
[0039] As the moving part 202 moves, the distance measuring device 3 rotates 1° relative to the center of the circular track 201, measuring the distance from the outer wall of the pipe to the distance measuring device 3 once. After the moving part 202 moves one revolution along the circular track 201, the distance data for one revolution of the outer wall of the pipe can be obtained.
[0040] Based on the measured distance data and the known coordinates of the rangefinder 3 at each point, the computer processes and calculates the coordinates of each point on the pipe surface, and calculates the deformation rate of the pipe.
[0041] By analyzing deformation rate data, it can be determined whether the pipeline meets the design requirements and whether there are problems such as excessive deformation.
[0042] In summary, this utility model provides a pipe deformation rate detection device, which includes a support mechanism 1 and a detection mechanism 2. The support mechanism 1 includes a base 101, and a tripod 102 is provided at the bottom of the base 101.
