Description

Technical Field

[0001] This application relates to the field of pile foundation testing technology, specifically to an auxiliary device for pile foundation testing. Background Technology

[0002] Pile foundation testing is an engineering testing activity that uses professional technical means to assess the single pile bearing capacity and pile integrity of a pile foundation, aiming to ensure the reliability and safety of building foundations. Static load testing is recognized as the most direct and reliable method for testing the vertical compressive bearing capacity of piles. However, during static load testing, workers may easily overlook minute changes in the pile foundation, leading to inaccurate pile foundation testing.

[0003] Therefore, there is an urgent need for an auxiliary device for pile foundation testing to solve the problem of insufficient accuracy in pile foundation testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an auxiliary device for pile foundation testing, which has the advantage of improving the accuracy of pile foundation testing and solves the problem of insufficient accuracy in pile foundation testing.

[0005] To achieve the above objectives, this application provides the following technical solution: an auxiliary device for pile foundation testing, comprising a base and a support plate welded to the top of the base, a testing mechanism being provided between two sets of support plates, and an indicating mechanism being provided on the outside of the support plate;

[0006] The detection mechanism includes a support rod, a threaded rod, a connecting plate, a connecting block, a support sleeve, a support frame, and a clamping plate. The two ends of the support rod are fixedly connected to the inner side of the connecting plate. The connecting plate is rotatably connected to the slot inside the support plate. The outer sides of the two ends of the threaded rod are rotatably connected to the inner side of the connecting plate. The inner side of the connecting block is threadedly connected to the threaded rod. The inner side of the connecting block is slidably connected to the outer surface of the support rod. One end of the support sleeve is fixedly connected to the outer side of the connecting block. The support frame is slidably connected to the inner side of the support sleeve. The support frame is provided with a scale for reading horizontal displacement. The clamping plate is rotatably connected to the inner side of the support frame.

[0007] By detecting the horizontal displacement and offset angle of the pile foundation, staff can easily and accurately observe changes in the pile foundation, thus improving the accuracy of pile foundation testing.

[0008] Preferably, the inner side of the clip is an arc-shaped plate.

[0009] Preferably, a knob is installed at one end of the threaded rod, and the threaded rod is connected to the connecting disc via a bearing.

[0010] Preferably, the threads on both sides of the threaded rod are in opposite directions.

[0011] Preferably, the indicating mechanism includes a support block, an indicating disk, and an indicating arrow. The support block is welded to the outside of the support plate, the outside of the support block is welded to the inside of the indicating disk, the outside of the indicating disk is provided with an angle, and the indicating arrow is fixedly connected to the rod extending from the support rod.

[0012] Preferably, the extension of the support rod is rotatably connected to the inside of the indicator dial.

[0013] In summary, this application includes at least one of the following beneficial effects:

[0014] 1. This auxiliary device for pile foundation testing adjusts the position of the connecting blocks. When two sets of connecting blocks approach each other, the connecting blocks drive the clamping plates to approach each other through the support sleeve and support frame. The two sets of clamping plates are clamped on the outside of the pile foundation. When the pile foundation shifts downward, the clamping plates will drive the support frame to slide inside the support sleeve, thereby detecting the amount of horizontal position shift of the pile foundation, which makes it convenient for staff to observe the small changes of the pile foundation.

[0015] 2. This auxiliary device for pile foundation testing, when the pile foundation shifts downward, the clamping plate drives the connecting plate to rotate through the support frame, support sleeve and support rod. When the connecting plate rotates, it drives the indicator arrow to rotate. When the indicator arrow rotates, it indicates the angle on the indicator plate, thereby determining the offset angle of the pile foundation. By detecting the horizontal displacement and offset angle of the pile foundation, the staff can easily and accurately observe the changes in the pile foundation, thus improving the accuracy of pile foundation testing.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1-4 An auxiliary device for pile foundation testing includes a base 1 and a support plate 2 welded to the top of the base 1. A testing mechanism is provided between the two sets of support plates 2, and an indicator mechanism is provided on the outside of the support plate 2.

[0023] With the above technical solution, the base 1 is fixed to the ground by a long screw. During the pile foundation testing process, the testing mechanism is fixed to the pile foundation. The small displacement of the pile foundation is detected by the testing mechanism. The staff can observe the changes of the pile foundation through the testing mechanism, making the pile foundation testing more accurate.

[0024] Specifically, the testing mechanism includes a support rod 111, a threaded rod 112, a connecting plate 113, a connecting block 114, a support sleeve 115, a support frame 116, and a clamping piece 117. The two ends of the support rod 111 are fixedly connected to the inner side of the connecting plate 113. The connecting plate 113 is rotatably connected to the groove inside the support plate 2. The outer sides of the two ends of the threaded rod 112 are rotatably connected to the inner side of the connecting plate 113. The inner side of the connecting block 114 is threadedly connected to the threaded rod 112. The thread directions on both sides of the threaded rod 112 are opposite.

[0025] Through the above technical solution, a protrusion is provided in the middle of the support rod 111 and the threaded rod 112 to separate the two sides of the support rod 111 and the threaded rod 112. The connecting plate 113 has an I-shaped structure and can rotate inside the support plate 2.

[0026] The connecting block 114 has through holes inside that correspond to the threaded rod 112.

[0027] The connecting block 114 is internally slidably connected to the outer surface of the support rod 111. One end of the support sleeve 115 is fixedly connected to the outside of the connecting block 114. The support frame 116 is slidably connected to the inside of the support sleeve 115. The support frame 116 is provided with a scale for reading the horizontal displacement. The clamping piece 117 is rotatably connected to the inside of the support frame 116. The inside of the clamping piece 117 is an arc-shaped plate. One end of the threaded rod 112 is equipped with a knob 118. The threaded rod 112 is connected to the connecting plate 113 through a bearing.

[0028] Through the above technical solution, the support frame 116 fits tightly inside the support sleeve 115, and the arc-shaped plate on the inner side of the clamp 117 can clamp the pile foundation. When the support frame 116 slides inside the support sleeve 115, the minute changes of the pile foundation can be observed by reading the scale.

[0029] Specifically, the indicating mechanism includes a support block 211, an indicator disk 212, and an indicator arrow 213. The support block 211 is welded to the outside of the support plate 2, and the outside of the support block 211 is welded to the inside of the indicator disk 212. The outside of the indicator disk 212 is provided with an angle. The indicator arrow 213 is fixedly connected to the rod extending from the support rod 111, and the rod extending from the support rod 111 is rotatably connected to the inside of the indicator disk 212.

[0030] Through the above technical solution, the support block 211 supports the indicator disk 212. When the pile foundation shifts downward, the clamp 117 drives the connecting disk 113 to rotate through the support frame 116, the support sleeve 115, and the support rod 111. When the connecting disk 113 rotates, it drives the indicator arrow 213 to rotate. When the indicator arrow 213 rotates, it indicates the angle on the indicator disk 212, thereby determining the offset angle of the pile foundation.

[0031] In use, the operator turns the knob 118, which drives the threaded rod 112 to rotate. When the threaded rod 112 rotates, it drives the connecting block 114 to move. By adjusting the position of the connecting block 114, when the two sets of connecting blocks 114 are close together, the connecting block 114 drives the clamping plate 117 to move closer through the support sleeve 115 and the support frame 116. The two sets of clamping plates 117 are clamped on the outside of the pile foundation. When the pile foundation shifts downward, the clamping plate 117 will drive the support frame 116 to slide inside the support sleeve 115, thereby detecting the amount of horizontal position shift of the pile foundation, which makes it convenient for the operator to observe the small changes of the pile foundation.

[0032] By detecting the horizontal displacement and offset angle of the pile foundation, staff can easily and accurately observe changes in the pile foundation, thus improving the accuracy of pile foundation testing.
