Description

Technical Field

[0001] This utility model relates to the field of pipeline wall thickness detection technology, and in particular to an auxiliary device for detecting the wall thickness of pipelines in water conservancy projects. Background Technology

[0002] In water conservancy projects, pipelines serve as crucial structures for water conveyance and drainage, and their wall thickness directly impacts their safety, durability, and operational efficiency. Regularly inspecting pipeline wall thickness is a key measure to prevent leaks, ruptures, and structural failures. Currently, ultrasonic thickness gauges are commonly used for inspection. However, in practice, pipelines located at high altitudes (such as overhead or jacking sections) are often difficult to access. Inspectors must rely on ladders, scaffolding, and other auxiliary tools, which is not only inconvenient and poses safety hazards but also results in low inspection efficiency, inaccurate positioning, and a high risk of missed detections or data deviations. Furthermore, handheld equipment has poor stability when working at heights, affecting the reliability of measurement results. Therefore, there is an urgent need for a device that can assist inspectors in safely, conveniently, and accurately inspecting the wall thickness of pipelines at heights.

[0003] To address this issue, we propose an auxiliary device for detecting the wall thickness of pipelines in water conservancy projects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for detecting the wall thickness of pipelines in water conservancy projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary device for detecting the wall thickness of a water conservancy project pipeline includes a handle, a support rod fixedly connected to the top of the handle, and a first threaded rod fixedly connected to the top of the support rod. A threaded sleeve and a rectangular sleeve are sequentially fitted on the surface of the first threaded rod from bottom to top. A support assembly is fixedly fitted on the surface of the support rod, and a rectangular cover is fixedly connected to the front of the support assembly. A support platform is fixedly connected to the top of the rectangular sleeve.

[0006] Preferably, the inner ring of the threaded sleeve has an internal thread that matches the external thread of the first threaded rod, and the threaded sleeve and the first threaded rod are threadedly connected.

[0007] Preferably, a second spring is fixedly connected to the inner top end of the rectangular sleeve, and a rectangular limiting block is fixedly connected to the bottom end of the second spring. When the external force is released, the second spring pushes the rectangular sleeve to reset when the threaded sleeve moves downward. The bottom end of the rectangular limiting block is fixedly connected to the top end of the first threaded rod.

[0008] Preferably, the rectangular cover has symmetrical slots on both sides, and insert rods are inserted into the slots. The rectangular cover also has first limiting rods symmetrically inserted on the left and right sides, and the sidewalls of the first limiting rods are fixedly connected to the insert rods.

[0009] Preferably, a first spring is sleeved on the surface of the insertion rod, and the first spring is located between the first limiting rod and the side wall of the rectangular cover. One end of the first spring is fixedly connected to the side wall of the rectangular cover, and the other end of the first spring is fixedly connected to the side wall of the first limiting rod.

[0010] Preferably, the support platform has a rectangular slot on its front side and a threaded hole on its back side, and a second threaded rod is inserted into the threaded hole.

[0011] Preferably, a second limiting rod is installed inside the support platform, and a third spring is fixedly connected to the back of the second limiting rod, with the other end of the third spring fixedly connected to the inner wall of the support platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting an adjustable height support structure (such as a support rod, threaded sleeve, rectangular sleeve and first threaded rod, etc.), can flexibly adapt to the needs of pipeline inspection at different heights. Operators can complete the wall thickness inspection of pipelines at high altitudes while standing on the ground, without the need to climb or build an auxiliary platform, which significantly improves the safety and efficiency of inspection.

[0013] 2. The device is equipped with a limiting mechanism (such as a first limiting rod, a first spring, a second limiting rod, and a second threaded rod) to fix the ultrasonic thickness gauge and its probe, which can stably fix the ultrasonic thickness gauge and its probe, avoid measurement errors caused by hand shaking during high-altitude operation, improve the accuracy and consistency of the test data, and has strong practicality and promotion value.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 An auxiliary device for detecting the wall thickness of a water conservancy project pipeline includes a handle 1, a support rod 2 fixedly connected to the top of the handle 1, and a first threaded rod 14 fixedly connected to the top of the support rod 2. A threaded sleeve 5 and a rectangular sleeve 6 are sequentially fitted on the surface of the first threaded rod 14 from bottom to top. A support component 9 is fixedly fitted on the surface of the support rod 2, and a rectangular cover 3 is fixedly connected to the front of the support component 9. A support platform 7 is fixedly connected to the top of the rectangular sleeve 6.

[0018] Furthermore, refer to Figure 4 It can be seen that the inner ring of the threaded sleeve 5 has an internal thread that matches the external thread of the first threaded rod 14. The threaded sleeve 5 and the first threaded rod 14 are threadedly connected. During use, the threaded sleeve 5 can be rotated and moved up and down along the surface of the first threaded rod 14 to facilitate the adjustment of the height of the rectangular sleeve 6 and adapt to pipes of different heights for wall thickness detection.

[0019] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the inner top end of the rectangular sleeve 6 is fixedly connected to the second spring 13, and the bottom end of the second spring 13 is fixedly connected to the rectangular limiting block 12. When the external force is released, when the threaded sleeve 5 moves downward, the second spring 13 pushes the rectangular sleeve 6 to reset by resetting. The bottom end of the rectangular limiting block 12 is fixedly connected to the top end of the first threaded rod 14. During use, the rectangular sleeve 6 can move up and down linearly along the surface of the rectangular limiting block 12. At the same time, when the rectangular sleeve 6 moves to the top end, the rectangular limiting block 12 abuts against its inner bottom, thus achieving the function of limiting.

[0020] Furthermore, refer to Figure 3 and Figure 4It can be seen that the rectangular cover 3 has symmetrical slots on both sides, and insert rods 11 are inserted into the slots. The rectangular cover 3 has first limiting rods 4 symmetrically inserted on the left and right sides, and the side wall of the first limiting rod 4 is fixedly connected to the insert rod 11. During use, the first limiting rod 4 moves linearly through the insert rod 11 to adjust the distance between the two sets of first limiting rods 4, which is convenient for use by detectors of different models and sizes.

[0021] Furthermore, refer to Figure 3 It can be seen that a first spring 10 is sleeved on the surface of the insertion rod 11, and the first spring 10 is located between the first limiting rod 4 and the side wall of the rectangular cover 3. One end of the first spring 10 is fixedly connected to the side wall of the rectangular cover 3, and the other end of the first spring 10 is fixedly connected to the side wall of the first limiting rod 4. During use, the first spring 10 pushes the first limiting rod 4 to abut against the side wall of the detector to achieve fixed positioning.

[0022] Furthermore, refer to Figure 5 It can be seen that the support platform 7 has a rectangular slot on the front and a threaded hole on the back. A second threaded rod 15 is inserted into the threaded hole. During use, the second threaded rod 15 is rotated to move and abut against the back of the second limiting rod 8, thereby facilitating the limiting of the second limiting rod 8 and realizing the limiting of the probe.

[0023] Furthermore, refer to Figure 4 and Figure 5 It can be seen that a second limiting rod 8 is installed inside the support platform 7, and a third spring 16 is fixedly connected to the back of the second limiting rod 8. The other end of the third spring 16 is fixedly connected to the inner wall of the support platform 7. During use, the third spring 16 can play a supporting and connecting role for the second limiting rod 8.

[0024] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, before the test, the staff inserts the detector into the rectangular cover 3. After the first limiting rod 4 and the first spring 10 cooperate to limit the position, the probe head is connected to the interface of the detector. Then the detector is inserted into the support platform 7, and the second threaded rod 15 is rotated to move and push the second limiting rod 8 to abut against the side wall of the probe head, thereby achieving the function of fixing and limiting. After the limiting is completed, the threaded sleeve 5 can be manually rotated to move along the surface of the first threaded rod 14 according to the height of the pipe, so as to push the rectangular sleeve 6 to move upward and realize the height adjustment, which is convenient for wall thickness testing of pipes at high positions. The operation is completed. The above is the complete working principle of this utility model.
