Description

Technical Field

[0001] This utility model relates to the technical field of pipe measuring devices, and more specifically, to a portable pipe diameter rapid measuring instrument. Background Technology

[0002] Currently, large-diameter municipal pipelines play a crucial role in China's booming municipal engineering construction system. Like the "blood vessels" of a city, they undertake key tasks such as water supply and drainage, gas transmission, and heat supply, ensuring the orderly and efficient operation of the city's daily life. In terms of product classification, domestic large-diameter municipal pipelines are mainly based on inner diameter series. These products are finely divided according to different inner diameter specifications, aiming to adapt to various complex and ever-changing municipal engineering application scenarios and meet the transportation needs under different flow rate, pressure, and other parameter requirements.

[0003] When measuring pipe diameter, it is essential to measure at the same vertical cross-section to ensure accurate and comparable data. However, large-diameter pipes are bulky and long, making it difficult to precisely locate them at the same vertical cross-section in practice. Measuring personnel may inadvertently cause positional deviations due to obstructed vision or limited operating space. If the positions are not at the same vertical cross-section, the measured data will not reflect the actual dimensions, leading to measurement errors. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in accurately measuring pipe diameter and to provide a portable pipe diameter rapid measuring instrument that facilitates the measurement of pipe diameter.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A portable pipe diameter rapid measuring instrument is provided, including a housing, a rotary encoder, a test rolling roller, a clamping assembly, and a display module. The rotary encoder is mounted on the housing, and the test rolling roller is connected to the input end of the rotary encoder. The clamping assembly is mounted on the housing, and a clamping gap exists between the clamping assembly and the test rolling roller. The display module is electrically connected to the output end of the rotary encoder, and the display module has a built-in data processing unit.

[0007] This portable pipe diameter rapid measuring instrument, when measuring the outer diameter of a pipe, involves placing the pipe within the clamping gap, placing the test roller against the outer wall of the pipe, and the clamping assembly against the inner wall of the pipe. Holding the outer casing, the measuring instrument is moved circumferentially along the pipe. Simultaneously, the test roller rotates on the outer wall of the pipe, driving a rotary encoder to rotate. The rotary encoder records the linear length data of the test roller's rotation in real time. When the roller completes one revolution, this linear length data represents the circumference of the pipe's outer wall. The data processing unit processes the linear length data and displays the resulting diameter data on the display module, thus completing the measurement of the pipe's outer diameter. When measuring the inner diameter of the pipe, simply flip the measuring instrument so that the test roller is against the inner wall of the pipe. By setting up test rolling rollers and clamping components, the measuring instrument is stably clamped on the pipe. The length data is obtained through a rotary encoder, and then the length data is converted into diameter by the data processing unit and displayed on the display module, which facilitates the rapid measurement of pipe diameter. At the same time, the measuring instrument has a simple structure and a small overall size, making it easy to carry.

[0008] Furthermore, the clamping assembly includes a clamping block, a sliding block, and an elastic element. The clamping block is connected to the sliding block, and a clamping gap exists between the clamping block and the test rolling roller. The sliding block is slidably connected to the housing, and both ends of the elastic element are connected to the sliding block and the housing, respectively. By setting the sliding block and the elastic element, the sliding block can be moved on the housing by compressing the elastic element, thereby changing the clamping gap and enabling the measuring instrument to measure pipes with different wall thicknesses.

[0009] Furthermore, the clamping assembly also includes a guide rod disposed on the housing, the sliding block being slidably connected to the guide rod, and the elastic element being a spring sleeved on the guide rod. By providing the guide rod, the movement of the sliding block and the spring is guided, allowing the test rolling roller and the clamping assembly to be clamped more stably.

[0010] Furthermore, the clamping assembly also includes an adjusting rod disposed on the sliding block, and the outer casing has a sliding hole through which the adjusting rod passes. By providing the adjusting rod, the sliding block can be manually moved, facilitating stable clamping of the measuring instrument on the pipe and improving measurement accuracy.

[0011] Furthermore, the outer casing is provided with a scale located at the sliding hole, and the scale is set along the sliding direction of the adjusting rod. The adjusting rod is provided with an indicator arrow. By setting the scale and the indicator arrow, when measuring pipes with different wall thicknesses, the movement of the clamping assembly drives the indicator arrow to move, so that the wall thickness of the pipe can be measured by reading the scale pointed to by the indicator arrow.

[0012] Furthermore, the clamping block is configured as a clamping roller, which is rotatably connected to the sliding block. The clamping roller and the test roller are respectively clamped on both sides of the inner and outer walls of the pipe, and roll together during movement to reduce motion resistance.

[0013] Furthermore, the clamping rollers are provided in two forms. The two clamping rollers and the test roller form a triangular structure, which makes clamping and movement more stable, thereby making the measurement results more accurate.

[0014] Furthermore, it also includes a unidirectional rotation mechanism connected to the test rolling wheel. By setting up the unidirectional rotation mechanism, the rotary encoder can only rotate in one direction, avoiding accidental reverse rotation during manual operation, thereby making the measurement results more accurate.

[0015] Furthermore, the unidirectional rotation mechanism includes a ratchet, a pawl, and a reset elastic element. The ratchet is coaxially connected to the test rolling wheel, the pawl is rotatably connected to the housing, and the two ends of the reset elastic element are respectively connected to the pawl and the housing. When the test rolling wheel rotates in the forward direction, the ratchet rotates, and the reset elastic element keeps the pawl abutting against the ratchet. When the test rolling wheel rotates in the reverse direction, the pawl restricts the movement of the ratchet, thereby preventing accidental reverse rotation during manual operation and making the measurement results more accurate.

[0016] Furthermore, it also includes a power module, which is connected to the housing. Both the rotary encoder and the display module are electrically connected to the power module. By including the power module, the measuring instrument becomes easy to carry and use.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model discloses a portable pipe diameter rapid measuring instrument. By setting a test rolling wheel and a clamping assembly, the measuring instrument is stably clamped on the pipe. The length data is obtained by a rotary encoder, and then the length data is converted into diameter by a data processing unit and displayed on a display module, which facilitates rapid measurement of pipe diameter. At the same time, the measuring instrument has a simple structure and a small overall size, making it easy to carry.

[0019] 2. This utility model discloses a portable pipe diameter rapid measuring instrument. By setting a sliding block and an elastic element, the sliding block can be moved on the outer shell by compressing the elastic element, thereby changing the clamping gap and enabling the measuring instrument to measure pipes with different wall thicknesses. At the same time, by setting a scale and an indicator arrow, when measuring pipes with different wall thicknesses, the movement of the clamping component drives the indicator arrow to move, so that the pipe wall thickness can be measured by reading the scale pointed to by the indicator arrow.

[0020] 3. The portable pipe diameter rapid measuring instrument of this utility model, by setting a unidirectional rotation mechanism, allows the rotary encoder to rotate only in one direction, avoiding accidental reverse rotation during manual operation, thereby making the measurement results more accurate.

[0028] Example 1

[0029] This embodiment is a first embodiment of a portable pipe diameter rapid measuring instrument, such as... Figure 1 and Figure 2 As shown, the device includes a housing 100, a rotary encoder 200, a test rolling roller 300, a clamping assembly 400, and a display module 500. The rotary encoder 200 is mounted on the housing 100. The test rolling roller 300 is connected to the input end of the rotary encoder 200. The test rolling roller 300 is cylindrical and rolls continuously on the pipe during measurement. Its outer wall material is a common anti-slip material to prevent slippage and improve measurement stability. Specifically, the test rolling roller 300... The device can be rotatably connected to the housing 100, allowing the housing 100 to support the test rolling roller 300. A clamping assembly 400 is mounted on the housing 100, with a clamping gap between the clamping assembly 400 and the test rolling roller 300. The display module 500 is electrically connected to the output of the rotary encoder 200. The rotary encoder 200 is a commercially available encoder capable of outputting line length or rotation angle. The display module 500 has a built-in data processing unit that processes the data from the rotary encoder 200 and displays the diameter on the display module 500. Specifically, the display module 500 includes a display screen and buttons. The display screen can be set to display line length and diameter, and the data displayed on the screen can be adjusted using buttons with different functions.

[0030] It also includes a power module 700, which is connected to the housing 100. The rotary encoder 200 and the display module 500 are both electrically connected to the power module 700. By including the power module 700, the measuring instrument becomes easy to carry and use.

[0031] The working principle of this portable pipe diameter rapid measuring instrument in this embodiment is as follows:

[0032] like Figure 4 As shown, when measuring the outer diameter of a pipe, the pipe is positioned within the clamping gap. The test roller 300 is placed against the outer wall of the pipe, and the clamping assembly 400 is placed against the inner wall of the pipe. A mark is made at the starting point of the pipe measurement. The outer casing 100 is held, and the measuring instrument is moved along the circumference of the pipe. During the measurement, the test roller 300 is kept rolling on the outer wall of the pipe. The rotation of the test roller 300 on the outer wall of the pipe drives the rotary encoder 200 to rotate. The rotary encoder 200 records the linear length data of the test roller 300 in real time. When the measuring instrument returns to the starting mark position, the measurement ends. This linear length data is the circumference of the outer wall of the pipe. The linear length data is processed by the data processing unit. Specifically, the built-in program uses the formula d = The diameter is calculated using C / π, where d is the diameter and C is the circumference. The resulting diameter data is displayed on the display module, thus completing the measurement of the pipe's outer diameter. To measure the inner diameter, simply flip the measuring instrument so that the test roller 300 abuts against the inner wall of the pipe. By using the test roller 300 and clamping assembly 400, the measuring instrument is stably clamped onto the pipe. The linear length data is obtained through the rotary encoder 200, and then converted into a diameter by the data processing unit and displayed on the display module 500, facilitating rapid pipe diameter measurement. Furthermore, the measuring instrument has a simple structure and a small overall size, making it easy to carry.

[0033] Example 2

[0034] This embodiment is the second embodiment of a portable pipe diameter rapid measuring instrument. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 2 and Figure 3As shown, the clamping assembly 400 includes a clamping block 410, a sliding block 420, and an elastic element 430. The clamping block 410 is connected to the sliding block 420, and there is a clamping gap between the clamping block 410 and the test rolling roller 300. The sliding block 420 is slidably connected to the outer shell 100, and both ends of the elastic element 430 are connected to the sliding block 420 and the outer shell 100, respectively. By setting the sliding block 420 and the elastic element 430, the sliding block 420 can slide on the outer shell by compressing the elastic element 430. The clamping force can be automatically adjusted according to the pipe wall height to ensure that the test rolling roller 300 maintains a constant contact pressure of 0.2-0.5N with the pipe surface, achieving real-time fit with the pipe contour, allowing this measuring instrument to measure pipes with different wall thicknesses.

[0035] The clamping assembly 400 also includes a guide rod 440, which is mounted on the housing 100. The sliding block 420 is slidably connected to the guide rod 440, and the elastic element 430 is a spring, which is sleeved on the guide rod 440. By setting the guide rod 440, the movement of the sliding block 420 and the spring is guided, making the test rolling roller 300 and the clamping assembly 400 clamp more stably. Specifically, there are two guide rods 440 and two springs, with two springs respectively sleeved on the two guide rods 440, making the support of the elastic element 430 for the sliding block 420 more stable.

[0036] Example 3

[0037] This embodiment is the third embodiment of the portable pipe diameter rapid measuring instrument. This embodiment is similar to embodiment two, except that, as Figure 2 As shown, the clamping assembly 400 also includes an adjusting rod 450, which is mounted on the sliding block 420. The housing 100 has a sliding hole 110 through which the adjusting rod 450 passes. By setting the adjusting rod 450, the sliding block 420 can be moved manually, making it easier for the measuring instrument to be stably clamped on the pipe and improving measurement accuracy.

[0038] like Figure 1 and Figure 2 As shown, the outer casing 100 is provided with a scale 120, which is located at the sliding hole 110. The scale 120 is set along the sliding direction of the adjusting rod 450, and the adjusting rod 450 is provided with an indicator arrow 451. By setting the scale 120 and the indicator arrow 451, when measuring pipes with different wall thicknesses, the movement of the clamping assembly 400 drives the indicator arrow 451 to move, so that the wall thickness of the pipe can be measured by reading the scale 120 pointed to by the indicator arrow 451.

[0039] Example 4

[0040] This embodiment is the fourth embodiment of the portable pipe diameter rapid measuring instrument. This embodiment is similar to embodiment two, except that, as Figure 3 As shown, the clamping block 410 is configured as a clamping roller, which is rotatably connected to the sliding block 420. The clamping roller and the test roller 300 are respectively clamped on the inner and outer walls of the pipe and roll together during movement to reduce motion resistance.

[0041] There are two clamping rollers. The two clamping rollers and the test roller 300 form a triangular structure, which makes clamping and movement more stable, thus making the measurement results more accurate.

[0042] Example 5

[0043] This embodiment is the fourth embodiment of the portable pipe diameter rapid measuring instrument. This embodiment is similar to embodiment one, except that, as Figure 3 As shown, it also includes a one-way rotation mechanism 600, which is connected to the test rolling wheel 300. By setting the one-way rotation mechanism 600, the rotary encoder 200 can only rotate in one direction, avoiding accidental reverse rotation during manual operation, thereby making the measurement results more accurate.

[0044] The one-way rotation mechanism 600 includes a ratchet 610, a pawl 620, and a reset elastic element. The ratchet 610 is coaxially connected to the test rolling wheel 300, and the pawl 620 is rotatably connected to the housing 100. The two ends of the reset elastic element are connected to the pawl 620 and the housing 100, respectively. When the test rolling wheel 300 rotates in the forward direction, the ratchet 610 rotates, and the reset elastic element keeps the pawl 620 abutting against the ratchet 610. When the test rolling wheel 300 rotates in the reverse direction, the pawl 620 restricts the movement of the ratchet 610, thereby preventing accidental reverse rotation during manual operation and ensuring more accurate measurement results.

[0045] Specifically, the reset elastic element can be a tension spring or a torsion spring. When the reset elastic element is a tension spring, the tension spring is mounted on the housing 100, and its two ends are connected to the pawl 620 and the housing 100, respectively. The tension spring ensures that the pawl 620 always abuts against the ratchet 610. When the reset elastic element is a torsion spring, the pawl 620 is rotatably connected to the housing 100 via a rotating shaft, and the torsion spring is sleeved on the rotating shaft, with its two ends connected to the pawl 620 and the housing 100, respectively.
