Description

Technical Field

[0001] This utility model relates to the technical field of foundation pile testing equipment, and in particular to a portable foundation pile acoustic transmission testing device. Background Technology

[0002] Acoustic transmission testing is a non-destructive testing technology for foundation piles based on the propagation characteristics of sound waves. By placing sound wave transmitting and receiving transducers inside a pre-set acoustic tube in the foundation pile, the changes in the propagation speed, amplitude, and frequency parameters of sound waves in the concrete medium are used to determine whether there are internal defects such as voids, cracks, and segregation in the pile body. This technology is widely used in the quality inspection of cast-in-place concrete piles and precast piles in building, bridge, and water conservancy projects, and is a key means to ensure the bearing capacity and structural safety of foundation piles.

[0003] Traditional acoustic wave transmission testing devices for foundation piles mainly consist of acoustic wave transmitting transducers, receiving transducers, data acquisition hosts, cables, and telescopic supports. In use, multiple acoustic logging tubes must first be pre-embedded in the foundation pile. Testing personnel then carry the device to the pile location, manually deploy the telescopic support, and fix the transducer position. The transducer is connected to the host via cables, and data is collected point-by-point by synchronously raising and lowering the transducer. However, traditional devices have large telescopic supports that lack integrated storage structures, requiring separate lifting during transport, increasing manpower. Furthermore, the transducers and cables lack organized storage components, resulting in messy and tangled wiring on-site, affecting testing efficiency. The data acquisition host and support are separate designs, and components are damaged due to bumps during movement.

[0004] To address the challenges of transporting traditional equipment, existing technologies have integrated the testing device, consolidating the data acquisition host and cables into a mobile housing. This housing facilitates overall transport. During use, personnel push the housing to the testing point, unfold the telescopic mechanism, and begin testing. After testing, the telescopic mechanism is disassembled and stored. However, existing technology still has problems. The telescopic mechanism and the mobile housing are separate designs, requiring manual handling during unfolding and storage. This is because the telescopic mechanism lacks a rigid connection to the mobile housing and cannot move synchronously with it. This necessitates repeated manual handling by personnel during site changes, increasing labor intensity and potentially causing component damage due to hand movement. This frequent handling is particularly problematic in construction sites with dense pile foundations, impacting testing progress and operational safety. Utility Model Content

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a portable acoustic wave transmission detection device for foundation piles, including a movable housing 1, which provides an installation foundation and housing space for the various components of the device. A fixing mechanism 2 is provided on the top of the movable housing 1 to realize the detachable fixing of the telescopic mechanism 3 to the movable housing 1. The telescopic mechanism 3 is provided on the top of the fixing mechanism 2, which can extend in multiple directions to adapt to different detection needs. A lid 4 is rotatably connected to the top of the movable housing 1, which can cover the top of the movable housing 1 to protect the internal components. Multiple winding drums and coils 5 are fixedly connected to the bottom of the inner wall of the movable housing 1 to store and organize the cables of the probes 6. The probes 6 are electrically connected to the left side of the multiple winding drums and coils 5, and are inserted into the acoustic tube to transmit and receive acoustic signals. A buffer pad 7 is provided in the middle of the inner wall of the movable housing 1 to provide shock absorption and buffer for the internal components and protect the data acquisition host 8. The data acquisition host 8 is provided on the top of the inner wall of the movable housing 1 to receive and process the detection data transmitted by the probes 6.

[0037] The fixing mechanism 2 includes a base 201, which provides an installation platform for other components of the fixing mechanism 2. The base 201 is fixedly connected to the top left side of the movable housing 1. Two spherical grooves 202 are opened on both the left and right sides of the inner wall of the base 201, which cooperate with the ball 205 to achieve locking and fixing. A slider 203 is slidably connected to the inner wall of the base 201, which slides along the inner wall of the base 201 to realize the storage and unfolding of the telescopic mechanism 3. Two springs 204 are fixedly connected to both the left and right sides of the inner wall of the slider 203, which provide elastic force to the ball 205 to keep it in the locking state with the spherical grooves 202. The opposite sides of the multiple springs 204 are fixedly connected to each other. A ball 205 is fixedly connected to the base 201 and cooperates with the spherical groove 202 to fix the slider 203 in the base 201. Multiple balls 205 are respectively engaged with the corresponding spherical grooves 202. A strap assembly 206 is provided on the top right side of the movable box 1 to further strengthen the connection between the telescopic mechanism 3 and the movable box 1. The strap assembly 206 includes two strap buckles 2061 to fix the end of the belt 2062. The two strap buckles 2061 are respectively fixedly connected to the front and rear sides of the top right side of the movable box 1. A belt 2062 is fixedly connected between the adjacent strap buckles 2061 to achieve binding and fixation around the telescopic mechanism 3.

[0038] Specifically, before the inspection operation, the telescopic mechanism 3 is housed within the fixed mechanism 2. At this time, the slider 203 of the fixed mechanism 2 slides along the inner wall of the base 201, and the springs 204 on both sides of the slider 203 are in a compressed state, causing the ball 205 to embed into the spherical groove 202 on the inner wall of the base 201, forming a rigid engagement, which firmly fixes the telescopic mechanism 3 to the top of the mobile housing 1, preventing shaking during transportation. When the equipment needs to be moved, the operator does not need to lift the telescopic mechanism 3 by hand. The strap assembly 206 on the right side of the mobile housing 1 further strengthens the fixation: the two ends of the belt 2062 are fixed to the top of the mobile housing 1 by strap buckles 2061, and the middle section passes around the slider 307 of the telescopic mechanism 3, and is locked by buckles to form a circumferential constraint with the spherical groove 202. The locking structure with the ball 205 forms a double fixation, ensuring that the telescopic mechanism 3 and the movable box 1 become a whole. When the telescopic mechanism 3 is unfolded during testing, simply press the ball 205 inward, and the compressed spring 204 will cause the ball 205 to disengage from the spherical groove 202, allowing the slider 203 and the connected telescopic mechanism 3 to be pulled out. After the operation is completed, push the telescopic mechanism 3 back to the base 201, and the ball 205 will automatically lock into the spherical groove 202 under the restoring force of the spring 204. The belt 2062 will be re-fastened, restoring the fixed state. Through the double fixation method of mechanical locking and strap binding, the telescopic mechanism 3 is always connected to the movable box 1. The operator only needs to push the movable box 1 to move the whole thing, completely solving the inconvenience of having to carry the telescopic mechanism 3 separately in traditional equipment.

[0039] Reference Figure 4 , Figure 6 and Figure 7The telescopic mechanism 3 includes a housing 301, which provides a mounting shell for other components of the telescopic mechanism 3. The housing 301 is fixedly connected to the top of the slider 203. A support rod 302 is fixedly connected to the middle right side of the housing 301, supporting and mounting the worm gear 303 and the support assembly 9. The left end of the support rod 302 is rotatably connected to the worm gear 303, which transmits power through meshing with the gear 306. The right end of the outer wall of the housing 301 has multiple sliding grooves 304, which guide the sliding of the threaded rod 305. The inner walls of the multiple sliding grooves 304 are slidably connected to the threaded rod 305, which drives the slider 307 to extend and retract through rotation. The left ends of the multiple threaded rods 305 are fixedly connected to the gear 306, which drives the worm gear 303 to extend and retract. The device rotates downwards, with multiple gears 306 meshing with the worm gear 303. Multiple threaded rods 305 are threadedly connected to slide rods 307 on their right sides, moving axially under the action of the threaded rods 305. Slide rods 308 are slidably connected to the outer walls of the slide rods 307, sliding along the slide rods 307 to expand the support range. A worm gear 309 is rotatably connected to the front side of the outer wall of the housing 301, driving the worm gear 303 to rotate. The worm gear 309 meshes with the worm gear 303. A turntable 310 is fixedly connected to the front end of the worm gear 309, facilitating rotation by the operator to drive the worm gear 309. Lifting components 311 are provided at the right ends of the slide rods 307 to adjust the support height to adapt to different terrains. Multiple slide rods 308... Support components 9 are provided between each support rod 302 and the support rod 307 to enhance the stability of the slide rod 308 after it is deployed. The lifting component 311 includes multiple support feet 3111, which contact the ground to provide support. The multiple support feet 3111 are respectively located at the right end of the corresponding slide rod 307. The upper and lower sides of the inner walls of the multiple slide rods 307 are provided with grooves 3112 to restrict the support feet 3111 to only perform vertical movement. The multiple support feet 3111 are slidably connected to the corresponding grooves 3112. The inner walls of the multiple support feet 3111 are threaded with threaded rods 3113, which drive the support feet 3111 to extend and retract by rotation. The left ends of the multiple threaded rods 3113 are fixedly connected with worm gears 3114. Driven by the rotation, multiple sliding rods 307 are rotatably connected to worm gears 3115 on their opposite sides, driving worm wheels 3114 to rotate. Multiple worm gears 3115 mesh with their corresponding worm wheels 3114. Turntables 3116 are fixedly connected to the opposite sides of multiple worm gears 3115, facilitating the operator to rotate and drive the worm gears 3115. The support assembly 9 includes multiple support rods 901, which are rotatably connected to the bottom of support rods 302. Sliding blocks 902 are rotatably connected to the opposite sides of multiple support rods 901. Sliding grooves 903 are opened on the adjacent sides of the bottom of multiple sliding rods 308, and the multiple sliding grooves 903 are slidably connected to their corresponding sliding blocks 902.

[0040] Specifically, during unfolding, rotating turntable 310 drives worm gear 309 to rotate. Worm gear 309 meshes with worm wheel 303, causing worm wheel 303 to drive gear 306 to rotate synchronously. Gear 306 drives threaded rod 305 to slide in slide groove 304. Threaded rod 305 engages with slide rod 307, pushing slide rod 307 to extend horizontally. Simultaneously, slider 902 in support assembly 9 slides along slide groove 903, and support rod 901 unfolds to form a triangular support, enhancing the stability of slide rod 308. When adjusting the height, rotating turntable 3116 drives worm gear 3115 to rotate worm wheel 3114, causing threaded rod 3113 to drive support foot 3111 along slide rod 304. 07. Axial telescopic adjustment adapts to different detection depth requirements. When encountering uneven road surfaces, the extension length of the corresponding support foot 3111 can be adjusted individually. Stable support is achieved through threaded self-locking. When retracting, the turntable 310 is rotated in the opposite direction, the threaded rod 305 rotates in the opposite direction, the slide rod 307 retracts into the outer shell 301, the gear 306 drives the worm gear 303 to reset, the support rod 901 of the support assembly 9 folds, the slider 902 slides back to the initial position of the slide groove 903, and the overall structure shrinks to its minimum volume, making it easy to fix and integrate with the movable box 1. Through the deceleration and force amplification characteristics of the worm gear and the precise control of the threaded transmission, this mechanism achieves the dual advantages of labor-saving operation and stable support, solving the problem of cumbersome adjustment of traditional telescopic structures.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The top of the outer casing 301 is provided with a sliding groove 10, which provides a path and guide for the sliding of the winding seat 11. The inner wall of the sliding groove 10 is slidably connected to the winding seat 11. Moving along the sliding groove 10 adjusts the placement position of the probe 6 cable. The front top of the movable housing 1 is fixedly connected to two door latches 12, which cooperate with hooks 13 to lock the cover 4. The front top of the cover 4 is fixedly connected to two hooks 13, which engage with the door latches 12 to fix the cover 4. The two hooks 13 engage with the corresponding door latches 12 respectively.

[0042] Specifically, the winding base 11 can slide along the slide groove 10 on the top of the outer casing 301, which makes it convenient to adjust the storage position of the probe 6 and the cable according to the detection requirements, and avoid the cable tangling. When the box cover 4 is closed, the hook 13 on its front side is aligned and engaged with the door latch 12 of the movable box body 1, so as to realize the secure closure of the box cover 4 and protect the internal equipment. When opening, the latch is released by pulling the latch, and the hook 13 is disengaged, so the box cover 4 can be opened, which is convenient to operate.

[0043] Reference Figure 1 , Figure 2 and Figure 5A support rod 14 is fixedly connected to the left side of the mobile box 1, supporting the handrail 15 and fixing it at a suitable height. The handrail 15 is fixedly connected to the top of the support rod 14, which is held by the operator to push the mobile box 1.

[0044] Specifically, the support rod 14 on the left side of the mobile housing 1 is vertically fixed, and the handle 15 on its top forms an easy-to-grip operating end. When moving the equipment, the operator holds the handle 15 and transmits the thrust through the support rod 14, which can easily push the mobile housing 1 to move as a whole without bending over or lifting by hand, thus improving the convenience of handling, especially when moving the site or adjusting the detection position.

[0045] Working principle: Before testing, when the device reaches the designated position of the acoustic tube, it is first filled with clean water as a coupling medium. The box cover 4 is opened, and the winding drum and coil 5, the probe 6 and the data acquisition host 8 are taken out from the movable box 1. The probe 6 is pulled out from the winding drum and coil 5 and placed in the corresponding acoustic tube. Then, the data is recorded through the data acquisition host 8. After the test is completed, the fixing mechanism 2 is retracted into the telescopic mechanism 3. At this time, the ball 205 expands outward under the elastic action of the spring 204 and engages with the spherical groove 202 to fix the telescopic mechanism 3. Then, the belt 2062 is wrapped around the slide bar 307 and engaged with the strap buckle 2061 to fix it. This effectively solves the problem of the telescopic mechanism 3 needing to be carried by hand and improves portability.

[0046] When the telescopic mechanism 3 needs to be deployed, pull the slide bar 308. The slider 902 slides along the slide bar 308 under the pulling force of the support rod 901, so that multiple slide bars 308 can be easily deployed horizontally and fixed. Then, shake the turntable 310, which drives the worm gear 309 to rotate. Through the meshing transmission between the worm gear 309 and the gear 306, the gear 306 and the threaded rod 305 are driven to rotate, thereby driving the slide bar 307 to extend, realizing the vertical deployment of the slide bar 308. If the road surface is uneven, shake the turntable 3116. Through the turntable 3116, the worm gear 3115 is driven to adjust the extension and retraction of the support foot 3111 to adapt to the road surface, avoiding the inconvenience of having to squat down and manually tighten the telescopic mechanism 3.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
