Technical Field
[0001] This application relates to the field of measurement auxiliary technology, and in particular to an auxiliary device for measuring the elevation of pipe pile positions. Background Technology
[0002] In the field of building construction, pile foundation construction is a crucial foundational step, and its quality directly affects the stability and safety of the entire building. With the acceleration of urbanization and continuous advancements in construction technology, building projects of various scales and types are emerging in large numbers, placing higher demands on the precision and efficiency of pile foundation construction. Accurate pile location measurement and positioning enable the pile foundation to better bear the load of the superstructure, reduce uneven settlement and other problems, thereby extending the service life of the building. Therefore, measurement, positioning, and verification technologies are playing an increasingly important role in pile foundation construction, becoming one of the key factors determining the success or failure of the project.
[0003] In traditional pile foundation construction, various methods are used for pile location measurement and positioning. On large construction sites, the site is typically leveled first to create favorable conditions for measurement. Then, a total station is used for precise surveying and setting out to determine the points. On smaller construction sites, a plumb line is often used to determine the axis position before construction. When verifying the pile position and elevation after the pipe pile construction is completed, the conventional practice is to manually determine the center of the pipe pile, then measure the actual distance between the pile position and the axis, and compare it with the design drawings to determine whether the pile position deviation and elevation meet the requirements.
[0004] However, during the verification process after the completion of pipe pile construction, the pile core is difficult to determine precisely, and since most pipe piles are circular, manual measurement can only be performed from the approximate location of the pile core. This leads to deviations between the measurement results and the actual pile core, resulting in inaccurate deviation values. This affects the accuracy of pile position and elevation verification, potentially causing problems in subsequent construction stages and seriously impacting construction quality. Therefore, to address the difficulty in accurately determining the pile core during pipe pile verification, this application proposes an auxiliary device for measuring the pile position and elevation of pipe piles. Utility Model Content
[0005] To address the problem of accurately determining the center of a pipe pile during the verification process, this application provides an auxiliary device for measuring the elevation of a pipe pile position.
[0006] This application provides an auxiliary device for measuring the elevation of pipe pile positions, which adopts the following technical solution:
[0007] An auxiliary device for measuring the elevation of a pipe pile includes a housing, within which a central gear and an arc-shaped rack are disposed. The central gear is rotatably connected to the housing, and a rotating shaft is disposed on the central gear in a vertical direction. The end of the rotating shaft away from the central gear passes through the housing and is fixedly connected to an adjusting wheel. Three arc-shaped racks are disposed, and any one of the arc-shaped racks meshes with the central gear in a horizontal direction. The housing has three telescopic openings. One end of any arc-shaped rack extends out of the housing through the telescopic opening, and an adjustable abutment component is disposed at the end of any arc-shaped rack extending out of the housing to form an abutment fit with the outer wall of the pipe pile.
[0008] By adopting the above technical solution, three arc-shaped racks that mesh with the central gear are set up. With the help of the adjusting wheel and the rotating shaft, the arc-shaped racks can extend and retract synchronously, which can adapt to pipe piles of different diameters. The adjustable abutment component at the end of the arc-shaped rack can abut against the outer wall of the pipe pile, which facilitates the accurate positioning of the pipe pile core. This solves the problem of the difficulty in accurately determining the pile core in the pipe pile verification work and improves the accuracy of pile position and elevation verification.
[0009] Preferably, the adjustable abutment assembly includes a connecting shaft rotatably connected to the end of the arc-shaped rack and an abutment block fixedly connected to the connecting shaft, wherein the abutment block forms an abutment fit with the outer wall of the pipe pile.
[0010] By adopting the above technical solution, the connecting shaft of the adjustable abutment component is rotatably connected to the end of the arc-shaped rack, so that the abutment block can flexibly adapt to the shape of the outer wall of the pipe pile and abut against the outer wall of the pipe pile, ensuring that the device is stably placed on the pipe pile and making it easy to accurately find the position of the core of the pipe pile.
[0011] Preferably, the side of the arc-shaped rack near the adjusting wheel has an anti-detachment groove along the length of the arc-shaped rack, and an anti-detachment pin is fixedly connected inside the housing, with the anti-detachment pin and the anti-detachment groove forming an embedded sliding fit.
[0012] By adopting the above technical solution, the anti-detachment pin and the anti-detachment groove on the arc-shaped rack form an embedded sliding fit, which can prevent the arc-shaped rack from detaching from the central gear and the housing during telescopic movement, ensuring the stability and reliability of the device operation and ensuring the normal operation of the measurement work.
[0013] Preferably, a limiting block is fixedly connected to the side of the arc-shaped rack away from the adjusting wheel along the length direction of the arc-shaped rack, and a limiting track is provided inside the housing, with the limiting block and the limiting track forming an embedded sliding fit.
[0014] By adopting the above technical solution, a limiting block is provided on the side of the arc-shaped rack away from the adjusting wheel, and a limiting track is provided inside the housing to form an embedded sliding fit with it. This allows the arc-shaped rack to slide stably along the limiting track during movement, preventing the arc-shaped rack from shaking or deviating during extension and retraction, and improving the stability and accuracy of the extension and retraction of the arc-shaped rack.
[0015] Preferably, the arc-shaped rack is provided with a scale.
[0016] By adopting the above technical solution, a scale is set on the arc-shaped rack, which makes it easy to read the diameter of the pipe pile corresponding to the extension length of the arc-shaped rack. This helps to improve the accuracy of the measurement, avoid errors caused by manual estimation, and thus improve the accuracy of the pipe pile position elevation measurement.
[0017] Preferably, the housing is provided with a bearing, and the rotating shaft is coaxially and fixedly connected to the bearing.
[0018] By adopting the above technical solution, the housing is equipped with a bearing and the rotating shaft is coaxially and fixedly connected to the bearing, which can reduce the friction when the rotating shaft rotates, improve the smoothness of the adjustment wheel rotation and the stability of the device, reduce wear, and extend the service life of the device.
[0019] Preferably, a pile center marker rod is provided on the side of the housing opposite to the adjusting wheel.
[0020] By adopting the above technical solution, a pile center marker rod is set on the side of the housing away from the adjusting wheel, which can accurately point to the pile center position, making it easier to identify and mark the pile center position and improve the accuracy of pile position and elevation verification.
[0021] Preferably, a locking nut is threaded onto the rotating shaft, and the locking nut forms an abutting fit with the housing.
[0022] By adopting the above technical solution, a locking nut is threaded onto the rotating shaft. After the arc-shaped rack extends to the required measurement length, the locking nut can be rotated to abut against the housing, thereby preventing the arc-shaped rack from loosening due to external force during the measurement process, which helps to improve the accuracy of measuring the pile position and elevation.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The rotating adjusting wheel drives the central gear to rotate, and the three arc-shaped racks meshing with it extend and retract through the telescopic port. They cooperate with the adjustable abutment component to abut against the outer wall of the pipe pile, so as to accurately determine the pile center, avoid the deviation of manual measurement, and improve the accuracy of pile position and elevation verification. The anti-detachment pin and the anti-detachment groove on the arc-shaped rack form an embedded sliding fit, which can prevent the arc-shaped rack from detaching from the central gear and the housing during telescopic movement. The limit block and the limit track form an embedded sliding fit, which can make the arc-shaped rack slide stably along the limit track during movement, and prevent the arc-shaped rack from shaking or deviating during telescopic movement.
[0025] 2. The arc-shaped rack is equipped with a scale, which can directly measure relevant data of the pipe pile, saving measurement time and improving measurement efficiency. The bearing and the rotating shaft are coaxially fixed, which can reduce the friction when the rotating shaft rotates, improve the smoothness of the adjustment wheel rotation and the stability of the device. A pile center marking rod is set on the side of the housing away from the adjustment wheel, which makes it easy to identify and mark the pile center position, improving the accuracy of pile position and elevation verification. A locking nut is threaded on the rotating shaft. Rotating the locking nut can abut against the housing, thereby locking the extension length of the arc-shaped rack. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.
[0030] This application discloses an auxiliary device for measuring the elevation of pipe pile positions.
[0031] Reference Figure 1 and Figure 2An auxiliary device for measuring the elevation of pipe piles includes a housing 1, which is cylindrical. In this embodiment, the housing 1 includes a first housing 11 and a second housing 12, which are detachably fixedly connected by bolts. A central gear 2 and an arc-shaped rack 3 are disposed inside the second housing 12. The central gear 2 is rotatably connected to the second housing 12. In this embodiment, a positioning bearing 21 is coaxially fixedly connected to the side of the central gear 2 away from the first housing 11, and the positioning bearing 21 is installed at the center of the second housing 12. A rotating shaft 4 is rotatably connected to the first housing 11, with one end of the rotating shaft 4 near the center of the central gear 2 located at the center of the central gear 2, and the other end of the rotating shaft 4 away from the center. One end of the central gear 2 is fixedly connected to an adjusting wheel 5 by welding. In this embodiment, the central gear 2 has a keyway 22 at the center of the circle near the first housing 11. The shaft 4 is fixedly connected to a key 41 by welding at one end near the central gear 2, and the keyway 22 and the key 41 form a plug-in engagement. There are three arc-shaped racks 3, and any one of the arc-shaped racks 3 meshes with the central gear 2 in the horizontal direction. The second housing 12 has three telescopic openings 121. One end of any one of the arc-shaped racks 3 extends out of the second housing 12 through the telescopic opening 121, and the end of any one of the arc-shaped racks 3 extending out of the second housing 12 is provided with an adjustable abutment component 6 that forms an abutment engagement with the outer wall of the pipe pile.
[0032] In practical use, the central gear 2 is rotatably connected to the center of the second housing 12 through the positioning bearing 21 to form a stable support. The rotating shaft 4 and the plug key 41 are plugged into the keyway 22 on the central gear 2. The central gear 2 can be driven to rotate by rotating the adjusting wheel 5 in conjunction with the rotating shaft 4, thereby driving the three arc-shaped racks 3 that mesh with the central gear 2 to extend out of the housing 1 synchronously through the telescopic port 121. This allows the device to adapt to pipe piles of different diameters. The adjustable abutment component 6 at the end of the arc-shaped rack 3 can abut against the outer wall of the pipe pile, which facilitates accurate positioning of the pipe pile center.
[0033] Reference Figure 1 and Figure 2 The adjustable abutment assembly 6 includes a connecting shaft 61 rotatably connected to the end of the arc-shaped rack 3 and an abutment block 62 fixedly connected to the connecting shaft 61. In actual use, the adjustable abutment assembly 6 is composed of the connecting shaft 61 and the abutment block 62, which can flexibly adapt to the shape of the outer wall of the pipe pile and abut against the outer wall of the pipe pile, ensuring that the device is stably placed on the pipe pile and making it easy to accurately find the position of the core of the pipe pile.
[0034] Reference Figure 1 and Figure 2The arc-shaped rack 3 has a closed anti-detachment groove 31 on the side near the adjusting wheel 5 along the length of the arc-shaped rack 3. An anti-detachment pin 111 is fixedly connected by welding near the meshing point between the arc-shaped rack 3 and the central gear 2 in the first housing 11. The anti-detachment pin 111 and the anti-detachment groove 31 form an embedded sliding fit. A limit block 32 is fixedly connected by welding on the side of the arc-shaped rack 3 away from the adjusting wheel 5 along the length of the arc-shaped rack 3. A limit track 122 is provided in the second housing 12 to form an embedded sliding fit with the limit block 32.
[0035] In practical use, the anti-detachment pin 111 forms an embedded sliding fit with the anti-detachment groove 31 on the arc-shaped rack 3 near the meshing point between the arc-shaped rack 3 and the central gear 2, which can prevent the arc-shaped rack 3 from detaching from the central gear 2 and the housing 1 during telescopic movement. Meanwhile, the limiting track 122 forms an embedded sliding fit with the limiting block 32 on the arc-shaped rack 3, which can make the arc-shaped rack 3 slide stably along the limiting track 122 during movement, and prevent the arc-shaped rack 3 from shaking or deviating during telescopic movement.
[0036] Reference Figure 1 and Figure 2 The arc-shaped rack 3 is provided with a scale 33. In this embodiment, the scale 33 is the length of the arc-shaped rack 3 extending out, which is the corresponding diameter of the pipe pile. In actual use, the scale 33 can easily read the pipe pile diameter corresponding to the length of the arc-shaped rack 3 extending out, which helps to improve the accuracy of measurement.
[0037] Reference Figure 1 and Figure 2 The first housing 11 is equipped with a bearing 112, and the inner ring of the bearing 112 is coaxially and fixedly connected to the rotating shaft 4. The rotating shaft 4 between the bearing 112 and the adjusting wheel 5 is provided with an external thread by machining, and a locking nut 42 is threadedly connected to the rotating shaft 4. In actual use, the coaxial and fixed connection between the rotating shaft 4 and the bearing 112 can reduce the friction force when the rotating shaft 4 rotates, reduce wear, and when the arc-shaped rack 3 extends to the required measurement length, the locking nut 42 can be rotated to make it form an abutment fit with the housing 1, thereby preventing the arc-shaped rack 3 from being loosened by external force during the measurement process and improving the measurement accuracy.
[0038] Reference Figure 1 and Figure 2 The second housing 12 is provided with a pile center marking rod 7 on the side opposite to the adjusting wheel 5. In this embodiment, the pile center marking rod 7 is coaxially and fixedly connected to the positioning bearing 21. In actual use, the pile center marking rod 7 is coaxially and fixedly connected to the positioning bearing 21 located at the center of the second housing 12, which can accurately point to the pile center position, making it easy to identify and mark the pile center position.
[0039] The implementation principle of this application embodiment is as follows: The central gear 2 set inside the housing 1 is connected to the external adjusting wheel 5 through the rotating shaft 4 set in the vertical direction. The rotating adjusting wheel 5 drives the central gear 2 to drive three horizontally meshing arc-shaped racks 3 to extend synchronously along the telescopic opening 121. The end of any arc-shaped rack 3 is connected to the abutment block 62 through the connecting shaft 61 to form an adjustable abutment component 6 that adapts to the outer wall of the pipe pile. The anti-detachment pin 111 and the anti-detachment groove 31 form an embedded sliding fit, which can prevent the arc-shaped rack 3 from detaching from the central gear 2 and the housing 1 during telescopic movement, ensuring the stability and reliability of the device operation. The limiting track 122 and the limiting block 32 form an embedded sliding fit, which can prevent the arc-shaped rack 3 from shaking or deviating during telescopic movement, ensuring telescopic stability.
[0040] The scale 33 on the arc-shaped rack 3 is directly related to the diameter of the pipe pile, which helps to improve the accuracy of the measurement and thus improve the accuracy of the pipe pile position elevation measurement. The bearing 112 on the housing 1 is fixedly connected to the rotating shaft 4 on the same axis, which can reduce the friction force when the rotating shaft 4 rotates, reduce wear, and extend the service life of the device. The rotating shaft 4 is provided with an external thread and a locking nut 42 is threadedly connected. By rotating the locking nut 42, it can be made to abut against the housing 1, thereby locking the extension length of the arc-shaped rack 3. The pile center marking rod 7 on the housing 1 is precisely pointed to the pile center, which is convenient for identifying and marking the pile center position and improving the accuracy of pile position and elevation verification.
[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
