Description

Technical Field

[0001] This utility model belongs to the field of length measuring instrument technology, specifically relating to a pipe length measuring device applied to intelligent building construction. Background Technology

[0002] In building construction, measuring the length of pipes (such as water supply and drainage pipes, HVAC pipes, cable conduits, etc.) is a crucial step in installation, acceptance, and cost accounting. Traditional measurement methods mainly rely on manual methods using measuring tapes or rangefinders. For example, a Chinese patent provides an instrument for measuring pipe length (patent publication number: CN220322207U). This instrument uses a spring to support a clamping plate, improving its stability. A sliding connection between a first slide rail and a first slider moves a movable plate, further enhancing its stability. Simultaneously, a first rubber pad adheres to the inner wall of the pipe, increasing friction between the clamping plate and the pipe's inner wall, thus improving the clamping plate's stability.

[0003] While the aforementioned technical solutions can effectively measure pipe length, using a measuring tape is prone to errors, and its accuracy is affected by the tensile strength and bending of the tape. Furthermore, it cannot measure curved pipes. Laser rangefinders, on the other hand, require high flatness of the pipe end face, and multiple calibrations are necessary when measuring irregularly shaped pipes (such as elbows and tees), making the operation time-consuming and labor-intensive. Therefore, there is currently a lack of a measuring device capable of quickly measuring the length of pipes that are straight or curved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pipe length measuring device for intelligent building construction, which solves the problem that current length measuring equipment cannot quickly detect the length of pipes that are straight or curved, resulting in the need to improve construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipeline length measuring device applied to intelligent building construction includes a support housing arranged directly above the pipeline and a plurality of sliders movably arranged on one side surface of the support housing. The support housing is rectangular in the horizontal plane, and the sliders are evenly spaced along the length direction of the support housing. Each slider is arranged along the width direction of the support housing and slides vertically through the bottom end of the support housing. A limiting component for synchronously fixing each slider is provided between each slider and the support housing. Two rollers moving along the width direction of the support housing are rotatably connected to the bottom end of the support housing, and the two rollers are symmetrically arranged about the axis in the length direction of the support housing. The outer surface of each roller is flush with the outer surface of the corresponding support housing. Two wheel number sensors respectively corresponding to the two rollers are arranged in the support housing. A display screen is arranged on the upper end surface of the support housing, and the display screen and the two wheel number sensors are commonly electrically connected to a control module arranged in the support housing.

[0007] Furthermore, a plurality of chutes respectively corresponding to the sliders are provided on the inner wall of the support housing. An elastic component is provided between each slider and the support housing. The elastic component includes sleeves arranged on both sides in the length direction of each slider and fixing rods. The two fixing rods are respectively arranged vertically in the corresponding chutes. The sleeves are all slidably arranged on the corresponding fixing rods. Springs are also coaxially sleeved on each fixing rod, and the two ends of the springs respectively abut against the upper end surface of the sleeve and the inner wall of the top end of the chute.

[0008] Furthermore, the limiting component includes iron blocks respectively arranged on both sides in the length direction of each slider and electromagnets corresponding to the iron blocks. The iron blocks are all embedded on the surface of the slider; the two electromagnets are arranged in the support housing and are symmetrically arranged about the axis in the length direction of the support housing; the two electromagnets are electrically connected to the control module.

[0009] Furthermore, connecting brackets that rotate in the vertical plane are jointly hinged on both side surfaces in the length direction of the support housing. A connecting sleeve is arranged on the surface of the connecting bracket, and the connecting sleeve is detachably connected to a support rod.

[0010] Furthermore, the outer surface of each roller is covered with a flexible anti-slip material.

[0011] Furthermore, each slider is in a "U" shape in the vertical plane.

[0012] Furthermore, an opening communicating with the inside is provided on the upper end surface of the support housing, and an upper cover is detachably connected to the upper end of the support housing. The display screen is arranged on the upper end surface of the upper cover.

[0013] The beneficial effects of the present utility model are as follows:

[0014] This invention achieves rapid and accurate measurement of pipe length through the collaborative design of a support shell and multiple sliders, combined with limiting components and roller structures. The sliders adaptively conform to the outer surface of the pipe to form an arc-shaped limit, ensuring stable movement of the rollers along the pipe axis. Combined with a roller count sensor and intelligent calculation module, it can accurately measure the length of straight or curved pipes, and display the results intuitively on a screen. The elastic components and electromagnet limiting design enhance the stability and reliability of the sliders, while the flexible anti-slip design effectively reduces roller slippage, and the support rod expands the measurement range. Furthermore, for scenarios with obstacles at both ends of the pipe, the program automatically compensates for the width of the support shell, effectively solving the measurement blind spot problem. The overall lightweight structure (e.g., the "U"-shaped slider) and modular design (removable top cover) balance portability, ease of maintenance, and cost advantages, significantly improving the efficiency and accuracy of pipe length measurement at construction sites.

[0015] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0024] like Figures 1-5 As shown,

[0025] A pipe length measuring device for intelligent building construction is placed on the outer surface of the pipe. It includes a support housing 1 positioned directly above the pipe and multiple sliders 2 movably disposed on one side of the support housing 1. The support housing 1 is rectangular in the horizontal plane, and the sliders 2 are evenly spaced along the length of the support housing 1 and along the width of the support housing 1. Each slider 2 slides through the bottom end of the support housing 1 in a vertical plane. A limiting component 3 is provided between each slider 2 and the support housing 1 for synchronously fixing each slider 2. Two rollers 4, which move along the width of the support housing 1, are rotatably connected to the bottom end of the support housing 1. The two rollers 4 are symmetrically arranged about the axis of the support housing 1 along its length, and the rotation centers of the two rollers 4 are both located on the axis of the support housing 1 along its width. The lower surfaces of the two rollers 4 protrude from the lower surface of the support housing 1 (see reference). Figure 4 The outer surface of each roller 4 is flush with the vertical outer surface of the corresponding support housing 1. The support housing 1 is equipped with two wheel count sensors 5, which correspond one-to-one with the two rollers 4. The working end of each wheel count sensor 5 faces the outer surface of the roller 4. The upper surface of the support housing 1 is equipped with a display screen 6, and the display screen 6 and the two wheel count sensors 5 are electrically connected to a control module (not shown in the figure, but can be a PLC or other intelligent processor) installed in the support housing 1.

[0026] As shown in the diagram, when measuring the length of a pipe, hold the support housing 1 horizontally above the pipe, ensuring that the length direction of the support housing 1 is perpendicular to the length direction of the pipe. At this point, the lower ends of each slider 2 will slide out of the support housing 1 under their own weight until they reach the bottom of their travel. Then, adjust the position of the support housing 1, ensuring that the line connecting the axes of the two rollers 4 is in the same vertical plane as the axis of the pipe. Next, move the support housing 1 closer to the pipe so that the outer surface of the pipe abuts against the bottom ends of the corresponding sliders 2. The sliders 2 abutted against the outer surface of the pipe will slide into the support housing 1. Continue moving the support housing 1 closer to the outer surface of the pipe until the outer surfaces of the two rollers 4 simultaneously abut against the outer surface of the pipe. At this point, because the bottom ends of the sliders 2 simultaneously abut against the outer surface of the pipe, the bottom surfaces of these sliders 2 together form an arc that fits against the outer surface of the pipe in the vertical plane (the specific shape is shown in the diagram). Figure 2The remaining sliders 2 that are not in contact with the outer surface of the pipe remain in their previous state (maintaining the position at the bottom of their previous stroke). At this time, the limiting component 3 fixes each slider 2 in its current position. Since multiple sliders 2 together form a shape that is in contact with the outer surface of the pipe, the support housing 1 can only slide along the axial direction of the pipe via the rollers 4. Then, the support housing 1 slides to the starting end of the pipe measurement via the rollers 4 (of course, we can also directly move the support housing 1 to the starting end of the pipe measurement, because each slider 2 has been fixed by the limiting component 3, and the shape of the pipe is consistent). The control module activates the wheel number sensor 5 and detects the rotation of the rollers 4. Then, the support housing 1 moves along the length of the pipe, and the two rollers 4 also rotate synchronously. When the support housing 1 moves to the pipe... After the end of the pipe (note that, taking one of the rollers 4 as a reference, the length that roller 4 has traveled is the measured length of the pipe), the number of rotations of roller 4 is detected by the roller number sensor 5 and the corresponding calculation is performed (the relevant calculation process and principle are existing technologies and will not be elaborated here). The length of the pipe can then be obtained, and the measured pipe length value will be displayed on the display screen 6, making it convenient for construction personnel to intuitively obtain the length. Similarly, when it is necessary to measure the length of a pipe with a curve, it is only necessary to move the support housing 1 and make the two rollers 4 travel over the curved pipe surface. Multiple sliders 2 will limit the support housing 1 to ensure that the path traveled by the two rollers 4 is the same as the axis of the pipe, while ensuring the accuracy of the final length detection. Moreover, the operation is simple and convenient, which greatly improves the construction efficiency of the workers.

[0027] Among them, when the pipes being tested are obstructed by walls or foreign objects at both ends (in combination with...) Figure 5 As shown in the diagram, at this time, the distance traveled by any roller 4 is less than the total length of the pipe being measured. To solve this problem, we can preset a corresponding program in the control module to add the width of the support housing 1 to the calculated distance to compensate for the length not traveled by the roller 4. First, before measurement, one side surface of the support housing 1 is placed against the surface of the foreign object. Then, the support housing 1 is moved to the other end of the pipe until the other side surface of the support housing 1 is against the surface of the foreign object. Through the preset program in the control module, the total length calculated by the number of rotations of the roller 4 needs to be added to the width of the support housing 1. The calculated data is the length of the pipe, which effectively solves the problem of length measurement when there are obstacles on both sides of the pipe. In addition, the combined action of multiple sliders 2 can make it abut against pipes of different diameters within a certain range, effectively expanding the applicable range of this device.

[0028] In this embodiment, the inner wall of the support housing 1 is provided with a plurality of grooves 7 corresponding to the sliders 2 one by one. Each slider 2 is provided with an elastic component 8 between it and the support housing 1. The elastic component 8 includes a sleeve 801 and a fixing rod 802 disposed on both sides of each slider 2 along its length. The two sleeves 801 are vertically placed and fixed on the two side surfaces of the slider 2. The two fixing rods 802 are vertically disposed in the corresponding grooves 7. The sleeves 801 are slidably disposed on the corresponding fixing rods 802. Each fixing rod 802 is also coaxially sleeved with a spring 803, and the two ends of the spring 803 abut against the upper end face of the sleeve 801 and the inner wall of the top of the groove 7, respectively.

[0029] As shown in the figure, when one end of each slider 2 extends out of the support housing 1 to its maximum distance, the corresponding spring 803 extends. At this time, one end of the slider 2 can be brought into contact with the vertically installed pipe. When the support housing 1 moves towards the pipe, the corresponding slider 2 slides into the support housing 1, and the corresponding spring 803 is compressed until the two rollers 4 respectively abut against the outer surface of the pipe. Finally, the limiting component 3 is used to fix each slider 2 in its current position. Compared with the method of slider 2 sliding out of the support housing 1 by its own weight, the use of the elastic component 8 can ensure that one end of each slider 2 can always be kept out of the support housing 1 when it is not in contact with the pipe surface. Moreover, when abutting against the pipe surface at different installation angles, multiple sliders 2 can always be pressed against the outer surface of the pipe, effectively ensuring the stability and efficiency of each slider 2.

[0030] In this embodiment, the limiting component 3 includes iron blocks 301 respectively disposed on both sides of each slider 2 along its length direction, and electromagnets 302 corresponding to the iron blocks 301. The iron blocks 301 are all embedded in the outer surface of the corresponding sleeves 801. The two electromagnets 302 are both disposed in the support housing 1 and are symmetrically arranged about the axis along the length direction of the support housing 1. The two electromagnets 302 are both electrically connected to the control module and, under the control of the control module, magnetically attract the iron blocks 301.

[0031] As shown in the figure, each slider 2 has an iron block 301 embedded on both sides of its length direction, corresponding to the electromagnet 302. When one end of the slider 2 comes into contact with the outer surface of the pipe and needs to be fixed in the current position, the electromagnet 302 is energized by the control module. The electromagnet 302 generates magnetism and attracts the iron block 301. The magnetic attraction between the electromagnet 302 and the iron block 301 is much greater than the tension of the spring 803, which can firmly fix the slider 2 in the current position. This ensures that when the support housing 1 moves along the length of the pipe, the arc formed by the bottom ends of the multiple sliders 2 in the vertical plane can stably fit with the pipe, preventing the support housing 1 from deviating and improving the accuracy of pipe length measurement.

[0032] In this embodiment, connecting brackets 9 that rotate in a vertical plane are jointly hinged to both side surfaces in the length direction of the support housing 1. A connecting sleeve 10 is provided on the surface of the connecting bracket 9, and a support rod 11 is detachably connected to the connecting sleeve 10 by means of a thread.

[0033] As shown in the figure, the support rod 11 is connected to the support housing 1 through components such as brackets and the connecting sleeve 10, which facilitates the staff to hold the support rod 11 and fix the support housing 1 on the outer surface of the pipeline. Moreover, by using the support rod 11 to indirectly drive the movement of the support housing 1, the movement range of the support housing 1 is expanded, enabling the staff to move the support housing 1 to a higher position, and indirectly expanding the measurement range of this device.

[0034] In this embodiment, the outer circumferential surfaces of all the rollers 4 are covered with a flexible anti-slip material. The flexible anti-slip material can be made of rubber, and anti-slip stripes are provided on its outer surface.

[0035] The flexible anti-slip material can effectively ensure that the rollers 4 are in contact with the outer surface of the pipeline, and increase the friction coefficient of the outer circumferential surface of the rollers 4, effectively preventing slipping during movement, and thereby indirectly improving the accuracy of pipeline length measurement.

[0036] In this embodiment, each of the sliders 2 is in a "U" shape in the vertical plane.

[0037] Combined with Figure 1 、 Figure 3 As shown, the "U"-shaped sliders 2 can effectively reduce their own weight and the cost during production, and do not affect the accuracy of measuring the pipeline length. At the same time, it is convenient for the staff to carry and turnover.

[0038] In this embodiment, an opening communicating with the inside is provided on the upper end surface of the support housing 1, and an upper cover 12 is detachably connected to the upper end of the support housing 1 through a snap structure. The display screen 6 is arranged on the upper end surface of the upper cover 12.

[0039] As shown in the figure, the detachably arranged upper cover 12 is convenient to open and display the inside of the support housing 1, facilitating the staff to maintain or service structures such as the sliders 2 and the elastic components 8, and extending the service life of this device.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
