Description

Technical Field

[0001] The present application relates to the field of ultrasonic technology for building foundation piles, and in particular to a line collection device for ultrasonic detection of foundation piles. Background Art

[0002] Ultrasonic testing of pile foundations refers to the use of sound wave transmission method to conduct integrity testing on the concrete cast-in-place pile body with pre-embedded acoustic detection tubes. Through ultrasonic testing of pile foundations, parameters such as the strength, depth, and length of the pile foundation can be evaluated, as well as defects and damage to the pile foundation can be detected, thereby determining the reliability and safety of the pile foundation.

[0003] During the ultrasonic testing of pile foundations, the testing personnel are required to extend the testing probe to the bottom of the pile foundation to be tested, and after the probe is stabilized, gradually reel in the probe to stretch it from the bottom of the pile foundation to the top, thereby achieving all-round testing of the pile foundation. However, since each probe transmission line is usually exposed to the outside and the transmission line is generally too long, the transmission line is easily entangled with the adjacent transmission line due to shaking during the testing process. The entanglement of the transmission lines will make it difficult for the testing personnel to smoothly arrange the probe and adjust the probe position, resulting in extended testing time and reduced testing efficiency, which is obviously insufficient. Utility Model Content

[0004] In order to improve detection efficiency, the present application provides a line collection device for ultrasonic detection of foundation piles.

[0005] The present application provides a line collection device for ultrasonic detection of pile foundations, which adopts the following technical solution:

[0006] A line gathering device for ultrasonic detection of foundation piles, comprising a mounting frame, the mounting frame being ring-shaped, a detection host being provided on the mounting frame, a line gathering assembly being provided on the mounting frame, the line gathering assembly being provided below the detection host, the line gathering assembly comprising a mounting ring provided on the mounting frame, a plurality of wire wheels being rotatably connected to the mounting ring, a transmission line being wound around each of the wire wheels, an ultrasonic probe being provided at the free end of the transmission line, a retractable line assembly being provided on the detection host, the retractable line assembly being used to realize the vertical placement and lifting of the ultrasonic probe.

[0007] By adopting the above technical solution, before testing, workers will independently wind each transmission line on the corresponding wire wheel. Under the guidance of the wire wheel, each transmission line slides stably along the tangent direction of the corresponding wire wheel. The setting of the wire collection component realizes the centralized management of the transmission line, and at the same time realizes the stable movement of the transmission line when winding and unwinding, avoiding the occurrence of entanglement and knotting of the transmission line due to shaking, so that the inspection personnel can arrange the probe and adjust the probe position more smoothly, shortening the inspection time and significantly improving the inspection efficiency.

[0008] Optionally, a bracket is provided on the detection host, and the wire reel assembly includes a rotating roller rotatably connected to the bracket, and the rotating roller is provided with a winding drum corresponding to the multiple wire wheels one by one, and the fixed end of the transmission line is fixedly connected to the winding drum, one end of the rotating roller extends to the outer surface of the bracket and is coaxially fixedly connected to a rotating shaft, and the end of the rotating shaft is provided with an anti-slip handle.

[0009] By adopting the above technical solution, the arrangement of multiple winding drums provides a clear storage position for the transmission line during the winding and releasing process. The winding drum releases the transmission line smoothly as the rotating roller rotates, avoiding the chaotic release of the transmission line while ensuring the orderly retraction of the transmission line, ensuring that the transmission line will not be randomly entangled or loose, and at the same time, the non-slip handle drives multiple transmission lines to be wound and released at the same time, further improving the efficiency and neatness of the transmission line winding and releasing, thereby further improving the detection efficiency.

[0010] Optionally, a lifting assembly is provided on the mounting frame, and the lifting assembly includes a first screw and a first guide rod arranged relatively to each other, the first screw is rotatably connected to the mounting frame in the length direction, the first guide rod is fixedly connected to the mounting frame, and a mounting plate is slidably connected to the mounting frame, one end of the mounting plate is threadedly connected to the first screw, and the other end is slidably connected to the first guide rod, the detection host is fixedly connected to the bottom surface of the mounting plate by bolts, and a first motor is provided on the mounting frame to drive the first screw to rotate.

[0011] By adopting the above technical solution, when the pile foundation specifications change, in order to avoid the pile foundation affecting the position of the detection host, the detection personnel can drive the first screw to rotate through the first motor. Under the guidance of the first guide rod, the first screw drives the mounting plate to move along the length direction of the mounting frame, and the mounting plate drives the detection host to move, thereby realizing the change of the vertical position of the detection host. The setting of the lifting and lowering group enables the detection personnel to quickly adjust the placement position of the detection host, further improving the detection efficiency.

[0012] Optionally, a limiting groove is provided on the bracket, and a rotation-stop component for limiting the rotational movement of the rotating shaft is provided on the limiting groove.

[0013] By adopting the above technical solution, when the probe detects a possible abnormal area, the probe needs to stay in the area to collect signal data of the abnormal area. At this time, the worker starts the anti-rotation component, which can effectively prevent the rotating roller from rotating accidentally, ensuring that the ultrasonic probe will not shake or change position due to the movement of the transmission line during the detection process, thereby improving the accuracy of the detection structure and reducing repeated detection or misjudgment caused by unstable transmission lines.

[0014] Optionally, the anti-rotation assembly includes an inner gear ring fixedly connected to the limiting groove, and a sliding groove is provided on the side walls opposite to the rotating shaft, and a slider is slidably connected in the sliding groove. A gear ring is commonly provided on the two sliders, and the gear ring is slidably connected to the rotating shaft. A first magnet is provided on the gear ring, and a second magnet for adsorbing the first magnet is provided on the inner side wall of the limiting groove. When the first magnet adsorbs the second magnet, the inner gear ring engages with the gear ring, and a pull ring is provided on the gear ring.

[0015] By adopting the above technical solution, when it is necessary to rotate the rotating roller, the worker pulls the pull ring outward, and the pull ring drives the gear ring to separate from the inner gear ring. At this time, the worker lifts the ultrasonic probe by turning the anti-slip handle. When the ultrasonic probe detects the existence of an abnormal area, the worker releases the pull ring, and the first magnetic block moves toward the second magnetic block under the adsorption force of the second magnetic block. The first magnetic block drives the gear ring to gradually approach the inner gear ring. When the first magnetic block and the second magnetic block are fitted, the gear ring is embedded in the inner gear ring. Since the inner gear ring is fixed in the limiting groove and cannot rotate, the gear ring cannot rotate. At the same time, under the connection between the slider and the slide groove, the rotating roller cannot rotate, thereby achieving the fixation of the position of the ultrasonic probe.

[0016] Optionally, a branching plate is provided on the mounting frame, and branching holes corresponding to the multiple wire wheels are opened on the branching plate, and the transmission line is passed through the branching holes. A driving assembly is provided on the mounting frame, and the driving assembly drives the branching plate to slide between the retractable assembly and the mounting ring.

[0017] By adopting the above technical solution, during the process of laying out the transmission lines, workers use the driving component to drive the distribution board to move between the detection host and the line collection component. During the movement of the distribution board, the layout of the transmission lines can be effectively standardized to avoid confusion such as crossing and entanglement of the transmission lines during the laying out process, ensuring that the path of the transmission lines is clear and neat, and improving the convenience and efficiency of the detection operation.

[0018] Optionally, the driving assembly includes a second screw and a second guide rod arranged opposite to each other, the second screw being rotatably connected to the length direction of the mounting frame, the second guide rod being fixedly connected to the mounting frame, one end of the branching plate being threadedly connected to the second screw, and the other end being slidably connected to the second guide rod, and a second motor is provided on the mounting frame to drive the second screw to rotate.

[0019] By adopting the above technical solution, the inspector turns on the second motor, and the second motor drives the second screw to rotate. Under the guidance of the second guide rod, the second screw drives the distribution plate to move along the length direction of the mounting frame. During the movement, the distribution plate effectively regulates the layout of the transmission line, avoiding confusion such as crossing and entanglement of the transmission line during the laying process.

[0020] Optionally, the mounting ring is detachably connected to the mounting frame via connecting bolts.

[0021] The aforementioned technical solution allows for a removable mounting ring connected to the mounting frame via bolts, making assembly and maintenance of the cable hub device extremely convenient. During installation, inspectors can easily secure the mounting ring to the mounting frame using the bolts, eliminating the need for complex tools and tedious installation steps. The mounting ring can also be quickly removed for repair, cleaning, or component replacement, improving work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application provides a line hub component that centrally manages the transmission line and ensures stable movement of the transmission line during winding and unwinding, preventing the transmission line from shaking and causing entanglement and knotting. This allows inspection personnel to arrange and adjust the probe position more smoothly, shortens inspection time, and significantly improves inspection efficiency.

[0024] 2. This application provides a lifting assembly; the lifting assembly enables the vertical position of the detection host to be changed, allowing the detection personnel to quickly adjust the placement of the detection host, further improving the detection efficiency;

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] An embodiment of the present application discloses a line collection device for ultrasonic detection of foundation piles.

[0033] Reference Figure 1 and Figure 2 A line collection device for ultrasonic detection of pile foundations includes a mounting frame 1, which is annularly mounted on the ground, with the length direction of the mounting frame 1 being perpendicular to the length direction of the pile foundation. A detection host 2 for ultrasonic detection is provided on the mounting frame 1, and brackets 21 are fixedly connected to the opposite side walls of the detection host 2. A wire reel assembly 3 is provided between the two brackets 21. The wire reel assembly 3 includes a rotating roller 31 rotatably connected between the two brackets 21, and a plurality of winding drums 32 are fixedly connected to the rotating roller 31. A transmission line 01 is wound on each winding drum 32, and a fixed end of each transmission line 01 is fixedly connected to the winding drum 32, and a free end is fixedly connected to an ultrasonic probe 02 for extending to the inside of the pile foundation. One end of the rotating roller 31 extends to the outer surface of the bracket 21 and is coaxially fixedly connected to a rotating shaft 33. The end of the rotating shaft 33 is fixedly connected to an anti-slip handle 34.

[0034] Reference Figure 1 and Figure 2 A wire gathering assembly 4 is provided on the mounting frame 1, and the wire gathering assembly 4 is provided below the detection host 2. The wire gathering assembly 4 includes a mounting ring 41 that is detachably connected to the mounting frame 1 through a connecting bolt 5. A wire pulley 42 corresponding to a plurality of winding disks 32 is rotatably connected to the mounting ring 41. The free end of each transmission line 01 extends downward and is wound around the wire pulley 42, and the ultrasonic probe 02 hangs below the wire pulley 42.

[0035] In order to ensure the stability and firmness of the pile foundation construction and avoid potential safety hazards, the pile foundation needs to be inspected after the pile foundation construction is completed. At this time, the mounting frame 1 is placed in a suitable inspection position, and the worker independently winds each transmission line 01 on the corresponding wire wheel 42. Then the inspector rotates the anti-slip handle 34 clockwise, and the anti-slip handle 34 drives the rotating roller 31 to rotate. When the rotating roller 31 rotates, the transmission line 01 wound on the winding drum 32 is released. As the transmission line 01 is released, the ultrasonic probe 02 will move along the wire wheel 42. The tangential direction slides steadily into the interior of the pile foundation. At the same time, the transmission line 01 falls steadily under the guidance of the corresponding wire wheel 42 to prevent the transmission line 01 from shaking and getting tangled. After reaching the detection position, the worker uses the ultrasonic probe 02 to detect the bottom of the pile foundation. After the detection is completed, the data is recorded and judged. Then, the anti-slip handle 34 is turned counterclockwise, and the rotating roller 31 drives the transmission line 01 to be retracted on the winding drum 32, so that the ultrasonic probe 02 is lifted along the length direction of the pile foundation, thereby realizing all-round detection of the interior of the pile foundation.

[0036] To sum up, the setting of the line hub component 4 realizes the centralized management of the transmission line 01, and at the same time realizes the stable movement of the transmission line 01 when winding and releasing the line, avoiding the occurrence of shaking and entanglement of the transmission line 01, thereby making it smoother for the inspection personnel to arrange the probe and adjust the probe position, shortening the inspection time and significantly improving the inspection efficiency.

[0037] Reference Figure 1 and Figure 2 A lifting assembly 6 is provided on the mounting frame 1, and the lifting assembly 6 includes a first screw 61 and a first guide rod 62 arranged opposite to each other. The length directions of the first screw 61 and the first guide rod 62 are parallel to the length direction of the mounting frame 1, wherein the first screw 61 is rotatably connected to the mounting frame 1, and the first guide rod 62 is fixedly connected to the mounting frame. A mounting plate 63 is slidably connected to the mounting frame 1, one end of the mounting plate 63 is threadedly connected to the first screw 61, and the other end is slidably connected to the first guide rod 62. The detection host 2 is fixedly connected to the bottom surface of the mounting plate 63 by bolts, and the top of the mounting frame 1 is fixedly connected to the first motor 64, and the output shaft of the first motor 64 is coaxially fixedly connected to the first screw 61.

[0038] When the pile foundation specifications change, in order to prevent the pile foundation from affecting the position of the detection host 2, the detection personnel can drive the first screw 61 to rotate through the first motor 64. Under the guidance of the first guide rod 62, the first screw 61 drives the mounting plate 63 to move along the length direction of the mounting frame 1, and the mounting plate 63 drives the detection host 2 to move, thereby realizing the change of the vertical position of the detection host 2. The setting of the lifting and lowering group allows the detection personnel to quickly adjust the placement position of the detection host 2, further improving the detection efficiency.

[0039] Reference Figure 2 and Figure 3 The bracket 21 is provided with a limiting groove 7, and a rotation-stopping assembly 8 is provided in the limiting groove 7. The rotation-stopping assembly 8 includes an inner gear ring 81 fixedly connected to the limiting groove 7, and a slide groove 331 is provided on the side wall opposite to the rotating shaft 33. The length direction of the slide groove 331 is parallel to the axial direction of the rotating shaft 33. A slider 82 is slidably connected in each slide groove 331, and a gear ring 83 is commonly connected on the two sliders 82. The gear ring 83 is slidably connected to the rotating shaft 33, and a first magnetic block 84 is fixedly connected to the end surface of the gear ring 83 facing the rotating shaft 33. A second magnetic block 85 for adsorbing the first magnetic block 84 is fixedly connected to the inner side wall of the limiting groove 7. When the first magnetic block 84 adsorbs the second magnetic block 85, the inner gear ring 81 meshes with the gear ring 83, and a pull ring 86 is fixedly connected to the end surface of the gear ring 83 facing away from the first magnetic block 84 to facilitate the detection personnel to pull.

[0040] When it is necessary to rotate the rotating roller 31, the worker pulls the pull ring 86 outward, and the pull ring 86 drives the gear ring 83 to disengage from the inner gear ring 81. The worker lifts the ultrasonic probe 02 by turning the anti-slip handle 34. When the probe detects a possible abnormal area, the probe needs to stay in the area to collect signal data of the abnormal area. At this time, the worker releases the pull ring 86, and the first magnetic block 84 moves toward the second magnetic block 85 under the adsorption force of the second magnetic block 85. The first magnetic block 84 drives the gear ring 83 to gradually approach the inner gear ring 81. When the first magnetic block 84 and the second magnetic block 85 are in contact, the gear ring 83 is embedded in the inner gear ring 81. Since the inner gear ring 81 is fixed in the limiting groove 7 and cannot rotate, the gear ring 83 cannot rotate. At the same time, under the connection between the slider 82 and the slide groove 331, the rotating roller 31 cannot rotate, thereby achieving the fixation of the position of the ultrasonic probe 02.

[0041] Reference Figure 1 and Figure 4 A branching plate 9 is provided between the line collection component 4 and the detection host 2. The branching plate 9 is slidably connected to the length direction of the mounting frame 1. The branching plate 9 is provided with branching holes 91 corresponding to multiple wire wheels 42. Each transmission line 01 is independently passed through the branching hole 91. A driving component 10 is provided on the mounting frame 1. Specifically, the driving component 10 includes a second screw rod 101 and a second guide rod 102 arranged opposite to each other. The length directions of the second screw rod 101 and the second guide rod 102 are parallel to the length direction of the mounting frame 1, wherein the second screw 101 is rotatably connected to the mounting frame 1, and the second guide rod 102 is fixedly connected to the mounting frame. One end of the branching plate 9 is threadedly connected to the second screw 101, and the other end is slidably connected to the second guide rod 102. The top of the mounting frame 1 is fixedly connected to the second motor 103, and the output shaft of the second motor 103 is coaxially fixedly connected to the second screw 101.

[0042] The inspector turns on the second motor 103, and the second motor 103 drives the second screw 101 to rotate. Under the guidance of the second guide rod 102, the second screw 101 drives the branching plate 9 to move along the length direction of the mounting frame 1. During the movement, the branching plate 9 effectively regulates the layout of the transmission line 01, avoiding the crossing, entanglement and other confusion of the transmission line 01 during the laying process, ensuring that the path of the transmission line 01 is clear and neat, and improving the convenience and efficiency of the inspection operation.

[0043] The implementation principle of the line collection device for ultrasonic detection of pile foundations in the embodiment of the present application is as follows: when detecting the pile foundation, the mounting frame 1 is placed at a suitable detection position, and the worker independently winds each transmission line 01 on the corresponding wire reel 42. Then the detection personnel rotates the anti-slip handle 34 clockwise, and the anti-slip handle 34 drives the rotating roller 31 to rotate. When the rotating roller 31 rotates, the transmission line 01 wound on the winding drum 32 is released. As the transmission line 01 is released, the ultrasonic probe 02 will slide steadily along the tangential direction of the wire reel 42 into the interior of the pile foundation. At the same time, the transmission line 01 will fall steadily under the guidance of the corresponding wire reel 42 to prevent the transmission line 01 from shaking and getting tangled. After reaching the detection position, the worker uses the ultrasonic probe 02 to detect the bottom of the pile foundation. After the detection is completed, the data is recorded and judged. Then, the anti-slip handle 34 is rotated counterclockwise, and the rotating roller 31 drives the transmission line 01 to be re-stored on the winding drum 32, so that the ultrasonic probe 02 is lifted along the length direction of the pile foundation, thereby realizing all-round detection of the interior of the pile foundation.

[0044] The setting of the line collection component 4 realizes the centralized management of the transmission line 01, and at the same time realizes the stable movement of the transmission line 01 when winding and releasing the line, avoiding the occurrence of shaking and entanglement of the transmission line 01, thereby making it smoother for the inspection personnel to arrange the probe and adjust the probe position, shortening the inspection time and significantly improving the inspection efficiency.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
