Abstract
Description
Technical Field
[0001] This application relates to the field of transmission and bearer technology, and in particular to an auxiliary measuring device and a communication pipeline laying equipment. Background Technology
[0002] With the development of communication information technology, the increased transmission throughput places higher demands on the dimensional accuracy and installation quality of communication pipes. However, in daily testing in product testing laboratories and mechanical performance laboratories, the dimensional measurement and sampling point positioning of communication pipes face significant challenges. Specifically, the diverse pipe specifications require the use of different measuring tools such as vernier calipers and micrometers, and the various testing methods used, such as the "six-point method" and "orthogonal method," demand high proficiency in tool use and method selection from testing personnel. Traditional measurement relies on manual sampling point location and marking, which is prone to errors due to uneven pipe cross-sections, visual angle errors, and improper human operation, leading to measurement point deviations and affecting quality tracking and accurate product quality feedback.
[0003] Currently, measuring tools often focus on fixing and limiting functions during pipe measurement. Specifically, fixing components are used to secure the pipe to be measured, preventing deviations caused by pipe movement during measurement, and limiting components are used to limit the position of the pipe, reducing errors. However, these measuring tools are more focused on measurement fixation assistance than positioning assistance, and most are designed for a single type of pipe, only suitable for measuring one size of pipe, resulting in poor versatility. Utility Model Content
[0004] This application is made in view of the above-mentioned problems. This application provides an auxiliary measuring device and a communication pipeline laying equipment.
[0005] According to one aspect of this application, an auxiliary measuring device is provided, comprising:
[0006] The auxiliary measuring body includes a first hollow conical pedestal and a second hollow conical pedestal symmetrically arranged vertically. The first and second hollow conical pedestals are integrally formed. The diameter of the first hollow conical pedestal gradually increases along the direction approaching the second hollow conical pedestal, while the diameter of the second hollow conical pedestal gradually decreases along the direction away from the first hollow conical pedestal. The maximum diameter ends of the first and second hollow conical pedestals are connected to each other. Multiple marking slots are provided through the circumferential direction of the conical surface of the second hollow conical pedestal. The multiple marking slots are evenly distributed in a circular array around the central axis of the auxiliary measuring body. Each marking slot extends along the generatrix of the conical surface of the second hollow conical pedestal. The top of the marking slot is close to the maximum diameter end of the second hollow conical pedestal. The maximum diameters of both the first and second hollow conical pedestals are 110mm to 150mm, and the minimum diameter of both the first and second hollow conical pedestals is 15mm to 30mm. The minimum diameter of the first hollow conical pedestal is larger than that of the second hollow conical pedestal.
[0007] Compared with existing technologies, the auxiliary measuring device in this application includes an auxiliary measuring body, which comprises a first hollow conical platform and a second hollow conical platform symmetrically arranged vertically. The first and second hollow conical platforms are integrally formed, ensuring structural stability and avoiding errors introduced during measurement due to component loosening, thus providing a rigid reference for pipe fitting and sampling positioning. The diameter of the first hollow conical platform gradually increases along the direction closer to the second hollow conical platform, and the maximum diameter ends of the first and second hollow conical platforms are connected to each other, with the minimum diameter being larger than the minimum diameter of the second hollow conical platform, facilitating operator grip or positioning of the device. The diameter of the second hollow conical platform gradually decreases along the direction away from the first hollow conical platform, with a minimum diameter of 15mm to 30mm and a maximum diameter of 110mm to 150mm. Through the tapered surface with gradually changing diameter, pipes with smaller inner diameters are inserted deeper, while pipes with larger inner diameters are inserted shallower, thereby enabling fitting of communication pipes with different inner diameters, achieving fitting of multiple specifications of pipes, and solving the problem of existing technologies "only suitable for a single size". Multiple marking slots are arranged circumferentially on the conical surface of the second hollow conical stage, allowing operators to directly contact the pipe surface using marking tools through these slots, avoiding marking misalignment caused by visual errors. Furthermore, the marking slots are evenly distributed in a circular array around the central axis of the auxiliary measurement body, with twelve equally divided rings corresponding to fixed positioning points in the circumferential direction. This directly matches the equal sampling requirements of detection methods such as the six-point method and orthogonal method. Each marking slot extends along the generatrix of the conical surface of the second hollow conical stage, covering the entire conical surface from the largest diameter end to the smallest diameter end. Regardless of the pipe insertion depth, the corresponding sampling position can be found through the slots.
[0008] It is evident that the auxiliary measuring device provided in this application can avoid the phenomenon of measurement point offset caused by factors such as uneven cross-section, visual angle, and improper human operation when the inspector uses vernier calipers to draw multiple points on the cross-section of the pipe to be measured. It also ensures the accuracy of the position, improves the inspection efficiency, and reduces human error.
[0009] According to another aspect of this application, a communication pipeline laying device is provided, including the aforementioned auxiliary measuring device.
[0010] Compared with the prior art, the beneficial effects of the communication pipeline laying equipment provided in this application are the same as those of the above-mentioned auxiliary measuring device, and will not be repeated here.
[0011] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.
[0019] Traditional measurement relies on manual sampling and marking, which is prone to errors due to uneven pipe cross-sections, visual angle errors, and improper human operation, leading to measurement point deviations and affecting quality tracking and accurate product quality feedback.
[0020] Currently, measuring tools often focus on fixing and limiting functions during pipe measurement. Specifically, fixing components are used to secure the pipe to be measured, preventing deviations caused by pipe movement during measurement, and limiting components are used to limit the position of the pipe, reducing errors. However, these measuring tools are more focused on measurement fixation assistance than positioning assistance, and most are designed for a single type of pipe, only suitable for measuring one size of pipe, resulting in poor versatility.
[0021] To address the aforementioned issues, this application provides an auxiliary measuring device to prevent measurement point offsets caused by factors such as uneven cross-section, visual angle, and improper human operation when inspectors use vernier calipers to draw multiple points on the cross-section of the pipe to be measured. This device ensures the accuracy of the measurement points, improves inspection efficiency, and reduces human error. Figure 1 This is a schematic diagram of the structure of the auxiliary measuring device according to an embodiment of this application. Figure 2 This is a bottom view illustrating an auxiliary measuring device according to an embodiment of this application. Figure 1 and Figure 2 As shown, the auxiliary measuring device includes an auxiliary measuring body 1, which includes a first hollow conical truncated platform 101 and a second hollow conical truncated platform 102 arranged symmetrically at opposite ends. The first hollow conical truncated platform 101 and the second hollow conical truncated platform 102 are integrally formed. The diameter of the first hollow conical truncated platform 101 gradually increases along the direction approaching the second hollow conical truncated platform 102, and the diameter of the second hollow conical truncated platform 102 gradually decreases along the direction away from the first hollow conical truncated platform 101. The first hollow conical truncated platform 101 and the second hollow conical truncated platform 102 are connected to each other at their maximum diameter ends. A through-beam is provided in the circumferential direction of the conical surface of the second hollow conical truncated platform 102. Multiple marking slots 1021 are provided, and these slots are evenly distributed in a circular array around the central axis of the auxiliary measuring body 1. Each marking slot 1021 extends along the generatrix of the conical surface of the second hollow conical stage 102. The top of the marking slot 1021 is close to the end with the maximum diameter of the second hollow conical stage 102. The maximum diameter of both the first hollow conical stage 101 and the second hollow conical stage 102 is 110mm to 150mm, and the minimum diameter of both the second hollow conical stage 102 is 15mm to 30mm. The minimum diameter of the first hollow conical stage 101 is larger than that of the second hollow conical stage 102. It should be understood that the number of marking slots 1021 can be either twelve or six, and can be adjusted according to the actual situation. No limitation is made here.
[0022] In practice, the operator inserts the lower part of the second hollow conical stage 102 of the auxiliary measuring device into the pipe. Because the multiple marking slots 1021 are evenly distributed in a ring and extend along the generatrix of the conical surface, the inspector can directly locate the sampling point through the corresponding marking slot 1021 according to the preset testing method. After the marking slot 1021 is located, the inspector can use tools such as vernier calipers and wall thickness micrometers to directly measure the inner diameter, outer diameter or wall thickness of the pipe at the marked sampling point. There is no need to manually find the point, which simplifies the operation and ensures the consistency of the measurement points of different inspectors and different batches, providing an accurate benchmark for quality tracking.
[0023] It is evident that the auxiliary measuring device provided in this application can avoid the phenomenon of measurement point offset caused by factors such as uneven cross-section, visual angle and improper human operation when the inspector draws multiple points on the cross-section of the pipe to be measured using vernier calipers, and ensure the accuracy of its position. According to experimental results, when using the auxiliary measuring device provided in this application embodiment for measurement, the detection efficiency is improved by 50% and the human error is reduced by 30%.
[0024] Understandably, when the second truncated cone of the auxiliary measuring body is placed inside the pipe port, all the marking slots are at least partially exposed outside the pipe port, ensuring that the slots are visible, providing an identification benchmark for positioning, and can be adapted to multiple pipe specifications, i.e. pipes with diameters between 35mm and 110mm.
[0025] During the process of inserting the lower part of the second hollow conical stage of the auxiliary measuring device into the inside of the pipe, if the inner diameter of the pipe is small (e.g., 15mm to 20mm), the second hollow conical stage can be inserted into the pipe shallowly so that the conical surface fits tightly against the inner wall of the pipe.
[0026] If the inner diameter of the pipe is large (e.g., 100mm to 150mm), the second hollow conical platform needs to be inserted deeper into the pipe, and its conical surface near the end with the largest diameter should fit against the inner wall of the pipe.
[0027] In one alternative approach, such as Figure 1 and Figure 2As shown, the marking groove 1021 in this embodiment has a width of 3mm to 5mm, which can accommodate common marking tools (such as markers and styluses) for insertion. This avoids the problem of tools being unable to enter due to a narrow groove width, while also preventing the marking tool from wobbling and causing the marking point to shift during the marking process due to a wide groove width, ensuring precise and controllable marking action. Furthermore, this width is sufficient for inspectors to clearly observe the relative position of the groove and the pipe surface, facilitating the alignment of sampling points. At the same time, an excessively wide groove does not weaken the strength of the conical surface structure of the second hollow conical stage 102, preventing deformation of the device due to localized thinness when inserting or removing it from the pipe. Moreover, the groove depth of the marking groove 1021 is consistent with the thickness of the conical surface of the second hollow conical stage 102, ensuring that the marking tool can directly contact the pipe surface through the groove, preventing the tool from being blocked by the conical surface material due to insufficient groove depth, thus losing its marking function.
[0028] Figure 3 This is a top view illustrating an auxiliary measuring device according to an embodiment of this application. Figures 1 to 3 As shown, in this embodiment of the application, the minimum diameter end of the first hollow conical stage 101 is coaxially provided with an outer shell 103. The first hollow conical stage 101 has a first hollow cavity, and the second hollow conical stage 102 has a second hollow cavity. The upper and lower ends of the outer shell 103 are connected and communicate with the first hollow cavity. The first hollow cavity communicates with the second hollow cavity. The auxiliary measuring device also includes a level 2, which is detachably disposed inside the outer shell 103.
[0029] In this embodiment, the outer casing 103 has an overall coaxial cylindrical structure. This casing 103 provides an independent and stable housing space, preventing the level 2 from being affected by vibration or collision due to direct contact with the conical platform. Simultaneously, the coaxial arrangement ensures that the measurement reference of the level 2 is aligned with the central axis of the auxiliary measuring body 1, guaranteeing calibration accuracy. Furthermore, as an extension of the smallest diameter end of the first hollow conical platform 101, the outer casing 103 facilitates the operator's grip, preventing slippage or structural damage caused by direct contact with the conical platform.
[0030] The level 2 in this embodiment can detect the placement status of the auxiliary measuring body 1 in real time, aiming to solve the problem of unevenness or bending of the pipe, thereby improving the accuracy and reliability of the measurement. When the pipe has an irregular shape, such as an uneven cross-section or overall bending, traditional measurement methods may lead to measurement errors. The level 2 can detect the horizontal state of the tool itself, ensuring that the measuring tool is parallel to the pipe measurement cross-section, thereby eliminating measurement deviations caused by unevenness of the pipe. This function enables the device to adapt to various pipe conditions, whether the pipe is straight, bent, or has a certain curvature, and can perform effective measurements, thereby improving detection efficiency and reducing the positioning error of sampling points.
[0031] The first hollow cavity in this embodiment reduces the weight of the auxiliary measuring body 1, facilitating operation. The second hollow cavity in this embodiment is connected to the first cavity, ensuring that the central axis of the main body runs through the entire device, providing a reference for coaxial positioning of the pipe.
[0032] Figure 4 This is a split schematic diagram illustrating an auxiliary measuring device according to an embodiment of this application. For example... Figures 1 to 4 As shown, in this embodiment, a limiting groove 1031 is provided at the upper end of the inner wall of the outer casing 103, and the level 2 is detachably disposed within the limiting groove 1031. By providing the limiting groove 1031 at the upper end of the inner wall of the outer casing 103, the level 2 is forced to maintain a preset relative position with the outer casing 103 during installation (e.g., the measuring reference surface of the level 2 is completely in contact with the groove surface of the limiting groove 1031). Furthermore, combined with the coaxial relationship between the outer casing 103 and the first hollow conical truss 101, it can further ensure that the measuring reference of the level 2 is strictly aligned with the central axis of the auxiliary measuring body 1, avoiding errors in subsequent levelness, coaxiality, and other measurement results due to installation misalignment of the level 2. Moreover, it also allows the level 2 to be stably placed within the outer casing 103.
[0033] For example, such as Figure 4 As shown, the bottom of the limiting groove 1031 in this embodiment of the application is provided with a light source input through hole b, which is connected to the first hollow cavity.
[0034] In practical implementation, in environments with insufficient lighting, operators can first observe the horizontal status of the auxiliary measuring device using a level 2 installed inside the housing 103. Adjusting the overall posture of the device (e.g., rotating or tilting the housing 103) until the level 2 indicates the main body is horizontal ensures the measuring tool is parallel to the pipe's measuring cross-section. Next, the operator can illuminate the interior of the first hollow cavity through the light source input hole b. The light travels along the first hollow cavity into the second hollow cavity and presents multiple light pillars through multiple marking slots 1021, thus marking the light source in low-light environments. Inspectors can use portable light sources such as mobile phone flashlights to directly project the sampling points onto the pipe surface. This function is particularly important in special scenarios, such as when inspecting goods directly at the point of shipment, especially in low-light conditions. The visible light-assisted positioning design considers the collimation of the light and the uniformity of the sampling points, ensuring clear visibility of the measurement points. This design allows light to be directly projected onto the pipe surface, forming clear measurement point marks, making operation more intuitive and accurate for inspectors.
[0035] Figure 5 This is a partially enlarged view of A in the auxiliary measuring device according to an embodiment of this application. For example... Figures 1 to 5As shown, in this embodiment of the application, the outer shell 103 is provided with a fastening component 104. The level 2 is detachably mounted in the limiting groove 1031 through the fastening component 104, so that the level 2 will not easily fall off after being placed, ensuring the stability of the level 2 after installation and reducing the occurrence of accidental loss of the level 2.
[0036] For example, such as Figure 5 As shown, the fastening assembly 104 in this embodiment includes a fastening seat 1041 and a fastening bracket 1042. The fastening seat 1041 is disposed on both sides of the level 2. The outer shell 103 has a pick-and-place slot 1032 at a position corresponding to the fastening seat 1041. The inner sidewall of the pick-and-place slot 1032 is provided with the fastening bracket 1042. The fastening seat 1041 and the fastening bracket 1042 are fastened together. In this embodiment, the fastening seat 1041 serves as the connecting carrier of the level 2, fixed on both sides of the level 2, and is equivalent to the connecting interface of the level 2. Its structure matches the fastening bracket 1042, providing basic support for fastening and ensuring the integration of the level 2 itself and the connecting component, thus preventing the level 2 from shifting during installation. In this embodiment, the fastening bracket 1042 can serve as a mating interface of the outer shell 103 and is disposed on the inner sidewall of the pick-and-place slot 1032, forming a precise fastening with the fastening seat 1041. In the locked state, the level 2 can be fixed in the limiting groove 1031 by mechanical clamping force, so as to realize the limiting of the level 2 after placement. The level 2 can be easily removed through the outer shell 103, so that the level 2 will not easily fall off after placement, ensuring the stability of the level 2 after installation and reducing the occurrence of accidental loss of the level 2.
[0037] It is understood that the buckle in this embodiment is a small block or sheet structure. The buckle includes a fixed end and a snap-fit end connected to the fixed end. The fixed end is the base of the buckle, and its shape perfectly matches the contours of the two side walls of the level. If the side wall of the level is flat, the fixed end is a flat rectangular block; if the side wall of the level is curved, the fixed end is an arc-shaped piece. Operators can fix the fixed end of the buckle to the side wall of the level by adhesive or screws. The snap-fit end of the buckle is the core part that enables the buckle to snap its fit. It is located on the side of the fixed end away from the level and has an elastic protrusion or hook-like structure. The specific shape must match the buckle frame.
[0038] For example, if the buckle is a slot type, the fastening end is an elastic protrusion with a barb, which makes it easy to slide into the buckle slot when fastening, and in the opposite direction, it forms a clamping force.
[0039] For example, if the buckle is a protrusion type, the fastening end is a slot with a limiting notch. The inner side of the slot is provided with an arc-shaped limiting protrusion that matches the curvature of the buckle protrusion. After fastening, the limiting protrusion locks the protrusion to prevent it from falling off naturally. The opening of the slot is chamfered to guide the buckle protrusion to slide in smoothly.
[0040] The actual selection of the above-mentioned buckle and buckle seat can be adjusted according to the actual situation, and no restrictions are imposed here.
[0041] In one alternative approach, such as Figures 1 to 4 As shown, the first hollow conical truncated pyramid 101 in this embodiment includes an increasing segment 1011 and a transition segment 1012 connected to the increasing segment 1011. The outer shell 103 is disposed on the smallest diameter end of the increasing segment 1011. The diameter of the increasing segment 1011 gradually increases as it approaches the transition segment 1012. The diameter of the transition segment 1012 gradually increases as it approaches the second hollow conical truncated pyramid 102. The largest diameter end of the transition segment 1012 is connected to the largest diameter end of the second hollow conical truncated pyramid 102.
[0042] In this embodiment, the smallest diameter end of the ascending segment 1011 is directly connected to the outer shell 103. Its tapered structure, with its diameter gradually increasing as it approaches the transition segment 1012, creates a smooth transition from the smallest diameter (the connection end of the outer shell 103) to the largest diameter (the connection end of the transition segment 1012). This design evenly distributes the weight of the outer shell 103 and the level 2 throughout the ascending segment 1011, avoiding stress concentration caused by abrupt changes in diameter at the connection point between the outer shell 103 and the tapered platform (e.g., directly connecting a small-diameter outer shell 103 to a large-diameter end), thus reducing the risk of deformation at the connection point after long-term use. Simultaneously, the fact that the ascending segment 1011 shares a central axis with both the outer shell 103 and the transition segment 1012 ensures that the horizontal reference of the outer shell 103 is smoothly transferred through the ascending segment 1011 to the transition segment 1012 and the second hollow tapered platform 102, preventing reference offset due to the segmented structure and ensuring the coaxiality accuracy of subsequent pipe positioning.
[0043] In this embodiment, the diameter of the transition section 1012 gradually increases as it approaches the second hollow conical truncated pyramid 102, and the end with the largest diameter connects to the end with the largest diameter of the second hollow conical truncated pyramid 102, forming a secondary gradient from the end diameter of the increasing section 1011 to the maximum diameter of the second hollow conical truncated pyramid 102. This design avoids the abrupt diameter change that may occur when the first hollow conical truncated pyramid 101 and the second hollow conical truncated pyramid 102 are directly connected, making the connection part of the two conical truncated pyramids more uniformly stressed. Especially when the second hollow conical truncated pyramid 102 is inserted into the pipe and subjected to radial force (e.g., compression from the inner wall of the pipe), the transition section 1012 can disperse the stress through its own conical surface, preventing the connection part from breaking due to stress concentration, and improving the deformation resistance of the overall structure.
[0044] For example, such as Figures 1 to 4As shown, in this embodiment, the tapered surface of the increasing segment 1011 in this application has multiple through holes a through it in the circumferential direction. These through holes a are evenly distributed in a circular array around the central axis of the auxiliary measuring body 1, reducing the weight of the auxiliary measuring body 1 and facilitating operation. Furthermore, the operator can insert their fingers (such as the index and middle fingers) into the corresponding through holes a in the circular array. The contact between the fingers and the inner wall of the through holes a forms a "mechanical locking," preventing the hand from sliding relative to the tapered surface of the increasing segment 1011. The multiple evenly distributed through holes a allow the operator to flexibly choose the gripping point according to hand size, and the force applied by the fingers is evenly distributed circumferentially on the increasing segment 1011, preventing uneven force distribution and tilting of the device due to single-point gripping, further enhancing operational stability.
