[0029] (III) Beneficial Effects

[0030] The beneficial effects of this utility model are as follows: The pipe measuring device of this utility model includes a first support frame, a translation mechanism, a first blocking mechanism, a second support frame, and a second blocking mechanism; the first blocking mechanism is slidably installed on the upper part of the first support frame, and the translation mechanism is installed in the middle of the first support frame. The output end of the translation mechanism is drivenly connected to the first blocking mechanism. The first support frame and the second support frame are arranged laterally on a straight line on the working surface, and the distance between the first support frame and the second support frame is fixed. The second blocking mechanism is fixedly installed on the upper part of the second support frame. The first support frame and the second support frame are used to place the pipe to be measured. The translation mechanism can drive the first blocking mechanism to move laterally to approach or move away from the second blocking mechanism. When the first blocking mechanism and the second blocking mechanism clamp the two ends of the pipe, the length of the pipe is measured by the lateral translation amount of the translation mechanism. Compared with the prior art, it can drive the first blocking mechanism to approach the second blocking mechanism through the translation mechanism, thereby clamping the two ends of the pipe by the first blocking mechanism and the second blocking mechanism. Finally, the length of the pipe is obtained by the translation amount of the translation mechanism. Its measurement is stable, effective, accurate, and not easily affected by external environmental interference.

[0031] The pipe measuring device of this utility model includes a second support frame comprising a chain box, a second lifting cylinder, and a second vertical guide assembly. The second lifting cylinder can drive the chain box to move up and down in the vertical direction. The chain box can release the rigid chain, and the end of the rigid chain is connected to a gauge. The gauge can extend into the inside of the pipe under the drive of the rigid chain to detect the gauge diameter.

[0032] The pipe measuring device of this utility model also includes a free stroke guide assembly and a compression spring. The free stroke guide assembly can maintain a certain distance between the first blocking mechanism and the piston rod end of the horizontal electric push cylinder. When the gauge extends from the pipe, the energy carried by the gauge will not be transferred to the piston rod of the horizontal electric push cylinder. Instead, it will be transferred by the first blocking mechanism to the compression spring through the clamping plate. The compression spring absorbs the energy from the gauge, which prevents the horizontal electric push cylinder from being subjected to energy impact and extends its service life.

Detailed Implementation

[0041] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 2 The orientation is used as a reference, and "left and right direction" is "lateral" and "front and back direction" is "vertical".

[0042] Reference Figure 1 , Figure 2 and Figure 3 This embodiment provides a pipe measuring device, including: a first support frame 2, a translation mechanism 3, a first blocking mechanism 4, a second support frame 5, and a second blocking mechanism 6.

[0043] The first blocking mechanism 4 is slidably installed on the upper part of the first support frame 2, and the translation mechanism 3 is installed in the middle of the first support frame 2. The output end of the translation mechanism 3 is drivenly connected to the first blocking mechanism 4. The first support frame 2 and the second support frame 5 are arranged laterally on a straight line on the working surface, and the distance between the first support frame 2 and the second support frame 5 is fixed. The second blocking mechanism 6 is fixedly installed on the upper part of the second support frame 5.

[0044] The first support frame 2 and the second support frame 5 are used to place the pipe 1 to be measured. The translation mechanism 3 can drive the first blocking mechanism 4 to move laterally closer to or away from the second blocking mechanism 6. When the first blocking mechanism 4 and the second blocking mechanism 6 clamp the two ends of the pipe 1, the length of the pipe is measured by the lateral translation of the translation mechanism. It should be noted that the first support frame 2 and the second support frame 5 can be fixedly set on the working surface or fixedly set on the ground. In addition, the left and right sides described in this article are... Figure 2 While orientation is the primary reference point, in actual use, due to the different positions of the observer, the directions described above may be reversed. Therefore, in this patent, "left side" and "right side" are relative concepts, not absolute directions.

[0045] The working process of the pipe measuring device in this embodiment is as follows: First, the pipe to be measured 1 is placed on the first support frame 2 and the second support frame 5; second, the translation mechanism 3 drives the first blocking mechanism 4 to translate to the right, so that the first blocking mechanism 4 abuts against one end of the pipe 1; third, the translation mechanism 3 continues to drive the first blocking mechanism 4 to translate to the right, so that the other end of the pipe 1 abuts against the second blocking mechanism 6. At this point, since the distance between the first support frame 2 and the second support frame 5 is fixed, the length of the pipe 1 can be obtained by the translation amount of the translation mechanism 3.

[0046] Combination Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the first support frame 2 includes a first lifting cylinder 201, a housing 202, and a first vertical guide assembly. The cylinder body of the first lifting cylinder 201 is supported on the working surface. The piston rod of the first lifting cylinder 201 passes through the bottom plate of the housing 202 and connects to the inner wall of the housing 202. The working surface is provided with first vertical guide assemblies on both sides of the housing 202, and the first vertical guide assemblies provide vertical guidance for the housing 202.

[0047] Specifically, the first vertical guide component of this embodiment includes two first lifting rails 203 and a plurality of first composite rollers 204. The two first lifting rails 203 are respectively arranged vertically on the working surfaces of the left and right sides of the housing 202. The outer surfaces of the housing 202 on both sides are provided with a plurality of first composite rollers 204 corresponding to the installation areas of the first lifting rails 203. The first composite rollers 204 are placed inside the first lifting rails 203 and can roll up and down along the first lifting rails 203.

[0048] In this embodiment, the translation mechanism 3 includes a horizontal electric cylinder 301 and a horizontal guide assembly. The horizontal guide assembly is disposed between the cover plate 205 of the housing 202 and the first blocking mechanism 4, and the horizontal guide assembly provides lateral guidance to the first blocking mechanism 4;

[0049] The housing 202 is fixedly equipped with a horizontally extending electric cylinder 301. The right side of the cover plate 205 is provided with a top opening. The piston rod end of the horizontal electric cylinder 301 is provided with a connector. After the connector passes through the top opening, it forms a driving connection with the first blocking mechanism 4.

[0050] Furthermore, the first blocking mechanism 4 includes a first side plate 401, a second side plate 402, and two symmetrically arranged bent side plates 403. Each of the two bent side plates 403 has an integrally formed upper vertical plate, a middle connecting plate, and a lower vertical plate. The two lower vertical plates are connected to the second side plate 402 on the side closest to the second support frame 5. The second side plate 402 is driven by the piston rod end of the horizontal electric push cylinder 301. The two upper vertical plates are connected to the first side plate 401 on the side furthest from the second support frame 5. The first side plate 401 is used to abut against the pipe fitting 1. It should be noted that the first side plate 401 is an M-shaped baffle.

[0051] The horizontal guide assembly includes two horizontal rails 302 and a plurality of second composite rollers 303. Two horizontal rails 302 extending laterally are arranged side by side on the upper surface of the cover plate 205. The lower vertical plates of the two bent side plates 403 are located between the two horizontal rails 302, and the second composite rollers 303 are arranged on the side of the lower vertical plates facing the horizontal rails 302. The second composite rollers 303 are placed inside the horizontal rails 302 and are able to roll horizontally along the horizontal rails 302.

[0052] During operation, the piston rod of the horizontal electric cylinder 301 extends and abuts against the second side plate 402 through the connector. The second side plate 402 drives the entire first blocking mechanism 4 to move to the right along the horizontal track 302, eventually causing the first side plate 401 to abut against the left end of the pipe 1.

[0053] In this embodiment, the second support frame 5 includes a chain box, a second lifting cylinder, and a second vertical guide assembly.

[0054] The cylinder body of the second lifting cylinder is supported on the working surface, and the end of the piston rod of the second lifting cylinder is hinged to the front side of the chain box. The working surface is provided with a second vertical guide assembly on the rear side of the chain box, and the second vertical guide assembly provides vertical guidance to the chain box. The second lifting cylinder is used to drive the chain box to lift and lower. The chain box is used to wind up and release the rigid chain. The end of the rigid chain is connected to a gauge, which can extend into the interior of the pipe 1 to check the gauge size of the pipe 1.

[0055] During operation, the chain box releases the rigid chain and drives the rigid chain to move to the left. The movement of the rigid chain causes the gauging gauge to enter the interior of pipe 1 and check whether the gauging size of pipe 1 meets the standard.

[0056] Furthermore, the second vertical guide assembly includes two lifting rails and multiple third composite rollers. Two second lifting rails extending vertically are provided on the working surface, and multiple third composite rollers are provided on the rear side of the chain box corresponding to the installation area of ​​the second lifting rails. The third composite rollers are placed inside the second lifting rails and can roll up and down along the second lifting rails.

[0057] The chain box drives the rigid chain and the gauge into the pipe 1 until the gauge extends from the left end of the pipe 1. However, when the gauge extends from the left end of the pipe 1, the huge energy carried by the gauge will impact the first blocking mechanism 4, and then be transmitted to the horizontal electric push cylinder 301, causing damage to the internal structure of the horizontal electric push cylinder 301.

[0058] To prevent the energy carried by the gauge from impacting the horizontal electric actuator cylinder 301, the pipe measuring device in this embodiment also includes a free stroke guide assembly and a compression spring 9. The free stroke guide assembly includes a guide bracket 7 and a fourth composite roller 8. The two bent side plates 403 have notches 405 in the mounting area adjacent to the second side plate 402. The notches 405 are used to accommodate the guide bracket 7. The piston rod end of the horizontal electric actuator cylinder 301 is connected to the guide bracket 7 through a connector. The fourth composite roller 8 is provided on both longitudinal sides of the guide bracket 7. The fourth composite roller 8 is placed in the horizontal track 302 and can roll horizontally along the horizontal track 302.

[0059] Two ear plates are respectively provided on the horizontal sides of the upper surface of the cover plate 205. A spring guide rod 10 extending horizontally is provided between the two ear plates. A clamping plate 11 is slidably sleeved in the middle of the spring guide rod 10. The two ends of the clamping plate 11 are respectively fixedly set on the lower vertical plates of the two bent side plates 403. A compression spring 9 is sleeved on the periphery of the spring guide rod 10, and one end of the compression spring 9 abuts against the clamping plate 11, while the other end of the compression spring 9 abuts against the ear plate on the left side of the cover plate 205.

[0060] The working process of the idle stroke guide assembly and the compression spring 9 in this embodiment is as follows:

[0061] First, the horizontal electric cylinder 301 pushes the idle stroke guide assembly to move to the right, the compression spring 9 is released, and the first blocking mechanism 4 is pushed to move to the right through the clamping plate 11.

[0062] Secondly, when the horizontal electric push cylinder 301 pushes the idle stroke guide assembly to contact the second side plate 402 of the first blocking mechanism 4, the horizontal electric push cylinder 301 and the compression spring 9 together push the front right side of the first blocking mechanism 4 to move until the first side plate 401 of the first blocking mechanism 4 abuts against one end of the pipe 1; the horizontal electric push cylinder 301 continues to extend, pushing the front right side of the pipe 1 to move until the other end of the pipe 1 abuts against the second support mechanism 6. At this time, the horizontal electric push cylinder 301 stops working, and the length of the pipe 1 is calculated by the extension of the piston rod of the horizontal electric push cylinder 301.

[0063] Next, after the pipe 1 is measured, the horizontal electric push cylinder 301 pulls the idle stroke guide assembly back 50mm. At this time, the compression spring 9 drives the first blocking mechanism 4 to abut against the pipe 1. The chain box drives the rigid chain and the gauge to enter the pipe 1 and move along the axial direction of the pipe 1. When the gauge extends from the left end of the pipe 1, the energy carried by the gauge will be transferred to the first blocking mechanism 4. The first blocking mechanism 4 transfers the energy to the compression spring 9 through the clamping plate 11, so that the compression spring 9 absorbs the energy from the gauge. At this time, since there is a certain distance between the second side plate 402 of the first blocking mechanism 4 and the idle stroke guide assembly, the energy will not directly impact the horizontal electric push cylinder 301.
