Description

Technical Field

[0001] This utility model relates to the field of steel pipe measuring equipment, and in particular to a high-temperature steel pipe size measuring device. Background Technology

[0002] Steel pipes are tubular materials made of steel. They are divided into seamless steel pipes and welded steel pipes. The production process of seamless steel pipes involves piercing a solid billet or steel ingot into a hollow tube, and then rolling it into a steel pipe of the required size. Seamless steel pipes are long strips of steel with a hollow cross-section and no seams around the perimeter. In the production process of high-temperature steel pipes, accurate dimensional measurement can ensure that the quality of the product meets the design requirements and avoid safety hazards caused by dimensional deviations. Especially in high-temperature environments, dimensional changes may affect the strength and stability of the steel pipe. Therefore, dimensional measurement of high-temperature steel pipes is very important.

[0003] In industries such as steel production, petrochemicals, and power, high-temperature steel pipes are widely used to transport high-temperature, high-pressure media, such as steam and hot oil. The dimensional accuracy of these high-temperature steel pipes plays a crucial role in the safe operation and performance of equipment. However, existing steel pipe dimensional measuring devices have many problems when measuring high-temperature steel pipes. Conventional measurement methods often require the measuring personnel to adjust the position of the measuring tool multiple times, perform multi-point measurements, and then calculate the average value. This operation is cumbersome and time-consuming. Moreover, in high-temperature environments, it is difficult for measuring personnel to operate close to the steel pipe for extended periods, further reducing measurement efficiency. For example, on steel plant production lines, measuring personnel need to measure the dimensions of a large number of high-temperature steel pipes in high-temperature, high-dust environments. Traditional measurement methods seriously affect production progress. Therefore, we propose a high-temperature steel pipe dimensional measuring device to solve the above problems.

[0023] 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.

[0024] Please see Figures 1-4 In this utility model, a high-temperature steel pipe dimension measuring device includes a support base 1. A square support plate 2 and a fine-tuning component 3 are fixedly connected to the outer surface of the support base 1. A laser displacement sensor 4 is provided at the top of the fine-tuning component 3. A square frame 5 is fixedly connected to the outer surface of the square support plate 2. An electric push rod 6 is fixedly connected to the upper surface of the square frame 5. A transmission disk 7 is fixedly connected to the output end of the electric push rod 6. Two sets of short rods 8 are fixedly connected to the outer surface of the transmission disk 7. A clamping plate 9 is fixedly connected to the outer surface of each set of short rods 8. A long connecting rod 10 is fixedly connected to the outer surface of the transmission disc 7. A receiver 11 is fixedly connected to the front end of the long connecting rod 10. A V-shaped seat 16 is fixedly installed on the upper surface of the square support plate 2 by multiple fastening nails 18. Protective pads 17 are provided on the outer surface of the pressing plate 9 and the outer surface of the V-shaped seat 16. The protective pads 17 are made of high-temperature resistant materials. For example, aluminum silicate ceramic fiber cotton is mainly made of high-purity alumina and silicon dioxide and other raw materials through a special process of melting and blowing or spinning. It has a soft texture, fine and long fibers, and a well-distributed structure. The device features uniformity and a temperature resistance exceeding 1000℃, with long-term operating temperatures reaching over 1000℃. It can even withstand higher temperatures in the short term without deformation or melting, ensuring clamping force while preventing damage to the steel pipe surface. Furthermore, the laser displacement sensor 4 and receiver 11 utilize high-temperature resistant materials. For example, the sensor's measuring head is made of special high-temperature resistant materials, such as zirconia ceramic, capable of withstanding temperatures above 1500℃. The laser displacement sensor 4 emits a laser beam, which, in conjunction with the receiver 11, measures the time from emission to reflection, thus accurately calculating the outer diameter of the steel pipe. This meets the high-precision requirements for measuring the dimensions of high-temperature steel pipes. The support base 1 provides stable support for the entire device. The square support plate 2 and square frame 5 are used to install other components. The electric push rod 6 drives the transmission disc 7, clamping plate 9, and other components to fix the high-temperature steel pipe. The long connecting rod 10 and receiver 11 work in conjunction with the laser displacement sensor 4 for dimensional measurement. The V-shaped seat 16 facilitates the placement of the high-temperature steel pipe.

[0025] Each clamping plate 9 has an indicator rod 12 fixedly connected to its outer surface. Two scale posts 13 are fixedly connected to the upper surface of the square support plate 2. The indicator rods 12 and scale posts 13 work together to visually display the position of the clamping plate 9, allowing operators to easily understand the fixing status and position adjustment of the steel pipe. This helps improve measurement accuracy and operational convenience. When adjusting the position of the clamping plate 9 to fix high-temperature steel pipes of different diameters, operators can observe the position of the indicator rods 12 on the scale posts 13 to directly observe the measurement distance. The fine-tuning component 3 includes an electric cylinder 301 fixedly installed on the outer surface of the support base 1. A horizontal connecting plate 302 is fixedly connected to the output end of the electric cylinder 301. A laser displacement sensor 4 is fixedly installed on the upper surface of the horizontal connecting plate 302. The outer surface of the horizontal connecting plate 302 is fixedly connected to... Two drag rods 303 are provided, and two guide grooves 304 are opened on the outer surface of the support base 1. Each guide groove 304 is slidably connected to a slide rod 305. The top of each slide rod 305 is fixedly connected to the bottom surface of the cross plate 302. When it is necessary to measure high-temperature steel pipes with different outer diameters, the position of the cross plate 302 is adjusted by the electric cylinder 301, which in turn drives the drag rods 303 and the laser displacement sensor 4 to move, so that the laser displacement sensor 4 can accurately align with the steel pipe for measurement, thereby meeting the measurement needs of high-temperature steel pipes of different sizes and improving the measurement accuracy. Moreover, during the process of fine-tuning the position of the laser displacement sensor 4, the slide rod 305 slides smoothly in the guide groove 304, ensuring that the cross plate 302 and the laser displacement sensor 4 can accurately move to the required position, so as to achieve accurate measurement of high-temperature steel pipes.

[0026] The outer surface of the square support plate 2 is provided with a notch 19 that matches the laser displacement sensor 4, so as to avoid the laser displacement sensor 4 from colliding with the square support plate 2 when it moves up and down. Two round sliding columns 14 are fixedly connected to the inner wall of the square frame 5. Each round sliding column 14 has a sliding plate 15 slidably connected to its outer surface. One end of each sliding plate 15 is fixedly connected to the outer surface of the short rod 8. When the electric push rod 6 pushes the transmission plate 7 to fix the pressure plate 9 to fix the high temperature steel pipe, the sliding plate 15 slides on the round sliding column 14 to ensure that the pressure plate 9 can move smoothly and accurately to the appropriate position and stably fix the steel pipe, so as to provide a guarantee for accurate measurement. The controller 20 and the display 21 are fixedly installed on the right side of the support base 1. The laser displacement sensor 4, the receiver 11 and the display 21 are all electrically connected to the controller 20 through wires. The worker can start the measuring device through the controller 20. After the laser displacement sensor 4 and the receiver 11 measure the size of the high temperature steel pipe, the data is transmitted to the controller 20. The controller 20 displays the result on the display 21. The worker can directly read the measurement data without manual calculation, which greatly improves the measurement efficiency and data accuracy.

[0027] The working principle of this utility model is as follows:

[0028] When measuring a steel pipe, simply place the pipe on the V-shaped seat 16, then start the electric push rod 6 to move the transmission disc 7 downwards. The movement of the transmission disc 7 will move the short rod 8 and the clamping plate 9, so that the two clamping plates 9 will press the two ends of the steel pipe together. At the same time, the movement of the transmission disc 7 will also move the long connecting rod 10 and the receiver 11. After the clamping plates 9 press the steel pipe together, the electric cylinder 301 can be started to move the horizontal connecting plate 302 and the drag rod 303, so that the two drag rods 303 contact the surface of the steel pipe. At the same time, the laser displacement sensor 4 will be moved upwards to a suitable position. Then, the laser displacement sensor 4 can emit a laser beam and reflect it in conjunction with the receiver 11. The distance is calculated based on the reflected light, thereby accurately measuring the outer diameter of the steel pipe. This device can quickly and accurately measure the size of the steel pipe when producing high-precision high-temperature steel pipes. Through the use of the controller 20, the measurement results can be displayed on the display 21.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
