Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection tools, specifically a tapered diameter pipeline inspection tool. Background Technology

[0002] Tapered pipe gauges are specialized tools used to inspect the dimensional accuracy of tapered pipes or fittings. They work by inserting a precision tapered measuring head that matches the pipe's taper into the pipe port to detect key parameters such as taper angle consistency and contact fit, ensuring the sealing and assembly reliability of pipe connections. They are widely used in fields such as petroleum, chemical, and hydraulic systems where high precision of tapered interfaces is required, and are core testing equipment for ensuring the quality of pipeline systems.

[0003] However, tapered pipe gauges face various complex scenarios during use. In some industrial environments, the operating space and time are extremely limited. Due to space constraints and time pressure, human shaking is prone to occur during operation, causing the tapered head to deflect, which leads to inaccurate detection and affects the safety and reliability of the pipeline in subsequent use. Therefore, a tapered pipe gauge is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A tapered pipe gauge includes an aperture measuring instrument 1, a reflective sleeve 2, and a fixed plate 3. A testing frame assembly 4 is fixedly connected to the outside of the fixed plate 3 by adhesive bonding. A transmission assembly 5 is installed inside the testing frame assembly 4. A pressure signal transmission plate 6 is disposed inside the testing frame assembly 4. A fixing mechanism 7 is fixedly connected to the lower end of the pressure signal transmission plate 6. The testing frame assembly 4 includes a base 41 with a threaded hole 42 at its upper end. A pressure buffer telescopic rod 43 is fixedly connected to the upper end of the base 41, and a precision measuring device is fixedly connected to the upper end of the pressure buffer telescopic rod 43. The semi-ring 44 has an inner light strip 45, the base 41 has an inner mounting groove 46, and the bottom of the base 41 has a bottom groove 47. The transmission component 5 includes an elastic shrink belt 51, a positioning short column 52 is fixedly connected to one side of the elastic shrink belt 51, a limit ring 53 is fixedly connected to the outside of the positioning short column 52, a compression spring 54 is fixedly connected to one side of the limit ring 53, a connecting column 55 is fixedly connected through the elastic shrink belt 51, a limit plate 56 is fixedly connected to the upper end of the connecting column 55, and a spiral rotating column 57 is fixedly connected to the upper end of the limit plate 56.

[0030] As a further implementation of this solution, the aperture measuring instrument 1 and the fixed plate 3 are fixed by a spiral connection. The aperture measuring instrument 1, the reflective sleeve 2 and the fixed plate 3 are on the same axis. Several parallel annular grooves are opened on the outer side of the reflective sleeve 2. The included angle between the pressure buffer telescopic rod 43 and the base 41 is 90°. The inner diameter of the precision detection semi-ring 44 is equal to the outer diameter of the fixed plate 3. The central axis of the reflective sleeve 2 and the central axis of the light strip 45 are on the same straight line. When the light strip 45 shines on the annular groove on the outer side of the reflective sleeve 2, the reflection of the groove can be used to quickly determine whether the aperture measuring instrument 1 is perpendicular to the pipe opening end face. The pressure buffer telescopic rod 43 can buffer the precision detection semi-ring 44 when it is subjected to external force, ensuring that the precision detection semi-ring 44 is not easily damaged or deformed.

[0031] As a further implementation of this scheme, the outer side of the elastic shrink band 51 is tightly attached to one side of the inner wall of the mounting groove 46. The positioning short column 52 is set inside the mounting groove 46. There are several positioning short columns 52, which are arranged in a ring inside the elastic shrink band 51. The positioning short column 52, the limiting ring 53 and the compression spring 54 are on the same axis. One end of the positioning short column 52 is arc-shaped. The diameter of the limiting ring 53 is 1.2 times the diameter of the positioning short column 52. One end of the compression spring 54 is fixedly connected to the base 41. The positioning short column 52 is more stable and reliable when positioning the pipeline, which can effectively prevent the pipeline from shaking or shifting during the detection process, thereby ensuring the accuracy of the detection results. The setting of the elastic shrink band 51 can make the positioning short column 52 shrink quickly, which is convenient for positioning pipelines of different diameters, improving the versatility and ease of operation of the device.

[0032] As a further implementation of this solution, two fixing mechanisms 7 are provided, symmetrically distributed at the lower end of the pressure signal transmission plate 6. Each fixing mechanism 7 includes a vacuum control module 71, with a suction cup rod 72 installed at the lower end of the vacuum control module 71. A vacuum suction cup 73 is fixedly connected to the lower end of the suction cup rod 72. Half of the vacuum suction cup 73 is set in a groove 47 opened at the bottom end of the base 41. The bottom surface of the vacuum suction cup 73 is parallel to the bottom surface of the base 41. The thickness of the edge area of ​​the vacuum suction cup 73 gradually increases towards the center. The two symmetrically distributed fixing mechanisms 7 can provide a more balanced adsorption force, effectively preventing the device from shifting or shaking during the detection process. The part of the vacuum suction cup 73 is set in the groove 47, which not only increases the stability of adsorption but also makes the bottom of the entire device flatter, facilitating fixation on different planes. The design of the thickness of the edge area of ​​the vacuum suction cup 73 gradually increasing towards the center can better adapt to the slight undulations of different planes, improve the sealing and reliability of adsorption, and further enhance the stability and safety of the device during fixation.

[0033] Workflow: When using this tapered pipe gauge in environments with extremely limited operating space, the aperture measuring instrument 1 can be rotated and installed into the fixed plate 3. This forms a single unit between the inspection frame assembly 4 and the aperture measuring instrument 1. The bottom of the base 41 is aligned with the plane, and one end of the pipe to be inspected is aligned with the lower end of the fixed plate 3. At this point, the LED strip 45 installed inside the precision inspection semi-ring 44, which is fixedly connected to the upper end of the pressure buffer telescopic rod 43, will emit light. When the light strip 45 illuminates the annular groove on the outside of the reflective sleeve 2, the reflection from the groove allows for quick determination of whether the aperture measuring instrument 1 is perpendicular to the pipe opening. Simultaneously, the pressure buffer telescopic rod 43 buffers the precision inspection semi-ring 44 from external forces, preventing damage or deformation. Next, the spiral column 57 is rotated. The spiral column 57 rotates in the threaded hole 42, thus penetrating into the base 41. The spiral column 57 drives the connecting column 55 to press against the pressure signal transmission plate 6. When the pressure signal transmission plate 6 receives the pressure, it sends a signal to the vacuum control module 71. Upon receiving the signal, the vacuum control module 71 activates the vacuum suction cup 73 via the suction cup rod 72, causing the vacuum suction cup 73 to adhere to the plane, thus fixing the device. At the same time, the rotation of the spiral column 57 drives the connecting column 55 to rotate, causing the connecting column 55 to deform the elastic contraction band 51 fixedly connected inside, resulting in contraction. This causes the multiple positioning short columns 52 to move centripetally, quickly positioning the pipe to the center position at the lower end of the fixed plate 3, facilitating the detection of the pipe diameter. Even with space constraints, the operation will not be deformed, preventing inaccurate detection results.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
