Description

Technical Field

[0001] This utility model relates to the field of pipeline displacement monitoring technology, specifically to a contact-type three-dimensional measurement device for pipeline expansion. Background Technology

[0002] In steam pipeline applications, pipeline expansion measurement presents challenges such as complex environments, large target sizes, and high accuracy requirements.

[0003] Compared to contact measurements, visual image-based measurements are more susceptible to interference and difficult to apply in this environment and under these conditions. Some contact measurements use traditional mechanical results, requiring personnel to observe and record pipeline expansion and offset information on-site. This method can only record pipeline expansion information and has low real-time performance; it is also prone to errors due to the influence of the working environment.

[0004] To improve the efficiency of real-time data collection and ease of operation for staff, it is necessary to propose further enhancements and improvements to the collection of steam pipeline expansion data.

[0005] Based on this, this utility model designs a contact-type three-dimensional measurement device for pipe expansion to solve the above problems. Utility Model Content

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A contact-type three-dimensional measurement device for pipe expansion, including a fixed base plate 7;

[0029] A scissor bracket 12 is fixedly connected to the upper end of the fixed base plate 7. The scissor bracket 12 is a scissor structure of a scissor-type heat pump mounting bracket structure disclosed in CN220750501U. The upper end of the scissor bracket 12 is connected to the lower end of the sensor base 4 through a universal ball joint 5. The upper end of the sensor base 4 is fixedly connected to the lower end of the main pipe 3. The upper end of the main pipe 3 is slidably connected to the telescopic protective tube 2. The upper end of the spring 10 is fixedly connected to the top of the inner side of the telescopic protective tube 2. The lower end of the spring 10 is... The upper end of the main pipe 3 is fixedly connected; the upper end of the telescopic protective pipe 2 is connected to the side wall of the connecting rod 8 through the universal ball joint 1; the right end of the connecting rod 8 is fixedly connected to the abutment block 11; the right end of the abutment block 11 abuts against the side wall of the pipe 9 being tested, and the right end of the abutment block 11 is provided with multiple protrusions to increase friction. The abutment block 11 is made of heat-insulating material, such as heat-insulating ceramic; the left end of the connecting rod 8 is connected to a limiting component for limiting the connecting rod 8; the lower end of the limiting component is connected to the upper end of the fixed base plate 7.

[0030] In this invention, the position of the connecting rod 8 is adjusted by the scissor bracket 12 so that the abutment block 11 abuts against the left side wall of the pipe under test 9. The pipe under test 9 expands due to heat, which drives the connecting rod 8 to move through the abutment block 11. The right end of the abutment block 11 is provided with multiple protrusions to increase friction and prevent the abutment block 11 from slipping and displacing relative to the pipe under test 9. The telescopic protective tube 2 slides relative to the main tube 3, and the spring 10 is compressed. An expansion amount is calculated by the telescopic sliding amount of the main tube 3 and the angular change of the universal ball joint 2 5. The abutment block 11 is made of heat-insulating material to prevent the connecting rod 8 from affecting the final calculation result due to thermal expansion.

[0031] The main tube 3 has a through groove inside, and a first sensor for detecting the relative displacement between the main tube 3 and the telescopic protective tube 2 is provided on the side wall of the through groove. The first sensor is electrically connected to the sensor base 4, and a data connector 6 for transmitting data is threaded to the front end of the sensor base 4.

[0032] The sensor base 4 is equipped with a distance sensor and a spatial deflection sensor.

[0033] In this invention, the telescopic sliding amount of the main pipe 3 is transmitted to the sensor base 4, and the data connector 6 transmits the position and angle change data of the sensor base 4 to the computer. The computer calculates and analyzes the spatial position change data of the device in real time, thereby obtaining the current pipeline expansion data, realizing digital and real-time monitoring, improving monitoring efficiency and the accuracy of pipeline displacement monitoring results.

[0034] The limiting assembly includes a limiting frame 13, a slide rail 14, a slide rod 15, a second spring 16, and a second sensor 17. The limiting frame 13 is fixedly connected to the upper left side of the fixed base plate 7; the right end of the limiting frame 13 is fixedly connected to the slide rail 14; the left end of the slide rod 15 is connected to the slider of the slide rail 14 through a universal ball joint 18, and the right end of the slide rod 15 is slidably connected to the left end of the connecting rod 8; the second spring 16 is sleeved on the outside of the connecting rod 8, the left end of the second spring 16 is fixedly connected to the slider of the slide rail 14, and the right end of the second spring 16 is fixedly connected to the left end of the connecting rod 8; the right end of the limiting frame 13 is fixedly connected to a second sensor 17 for detecting the deformation of the second spring 16 and the displacement of the slider of the slide rail 14.

[0035] In this invention, when the tested pipe 9 expands due to heating, the abutment block 11 drives the connecting rod 8 to move, and the connecting rod 8 slides relative to the slide rod 15. The second spring 16 contracts, and the connecting rod 8 drives the slide rod 15 to move downward under the limiting action of the slide rail 14. The second sensor 17 transmits the detected deformation of the slide rod 15 and the displacement of the slider of the slide rail 14 to the computer. Combined with the angular change of the universal ball joint 5, the data is processed to obtain another expansion amount of the tested pipe 9. The average of the two expansion amounts is taken to obtain the final expansion amount, thereby reducing errors and improving measurement accuracy.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
