Description

Technical Field

[0001] This invention relates to the field of seismic testing equipment technology, and in particular to a seismic strength testing device for bridge foundation piles. Background Technology

[0002] Seismic testing equipment for bridge foundation piles is divided into three categories: excitation equipment (low-strain hammers, high-strain hammers, steady-state vibrators, static load jacks) used to simulate earthquake impact / vibration; sensing equipment (accelerometers / force / displacement sensors, acoustic transducers) to collect data on pile stress, deformation, and acoustics; and data equipment (acquisition instruments, professional analysis software) to process data and generate indicators. The purpose of testing is to verify core indicators such as pile bearing capacity, dynamic stiffness, and concrete integrity, to identify defects such as cracks and voids in the piles, and to ensure that they can withstand impact during earthquakes without settling or fracturing. This prevents insufficient overall seismic performance of the bridge due to pile failure, and is a fundamental guarantee for bridge seismic safety. The detection method using acoustic transducers typically involves pre-burying 2-4 acoustic logging tubes, placing the transmitting and receiving transducers in different tubes, and filling the tubes with clean water as a coupling agent. The transducers are raised synchronously, and the acoustic parameters of the sound waves passing through the cross-section of the pile are measured point by point. The location and extent of defects are determined by criteria such as sound velocity, amplitude, and PSD, and the profile curve and textual conclusions are output. In order to ensure that the transducers are raised synchronously, the four cables must be pulled at a uniform speed and synchronously to ensure that all transducers are in the same depth plane. This way, the acoustic wave data collected are from the same cross-section, and the CT imaging is accurate.

[0003] Existing cable lifting methods mostly rely on manual operation using lifting supports. During testing, multiple cables are connected to transducers at one end, extend into corresponding sonic logging tubes, and then converge at the lifting support. Because the lifting support is usually only installed on one side, the cable lengths from each sonic logging tube to the support are inconsistent. Furthermore, manual operation makes it difficult to accurately control the lowering / lifting dimensions of each cable, which easily leads to transducer depth deviations. It is also impossible to quickly and accurately confirm whether all transducers are at the same pile depth plane. If the cable lengths relative to the lifting support can be standardized, the convenience and consistency of transducer depth adjustment will be greatly improved, ensuring the accuracy of the test data. Therefore, based on the above problems, this invention provides a bridge foundation pile seismic strength testing device to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a seismic strength detection device for bridge foundation piles. By setting a support component and a cable control component, the support component can adapt to different sizes of foundation piles and uneven detection sites. With multi-point horizontal adjustment, it can conveniently ensure that the transducers are kept on the same horizontal plane. The cable control component can symmetrically arrange four cables and unify their lengths to the lifting bracket, realizing precise synchronization of the transducer depth, quickly bringing the transducers to the same detection plane, meeting the detection requirements of the acoustic transmission method. Through the above settings, the problems in the existing traditional manual cable lifting method can be solved, such as the uneven cable routing lengths of the acoustic logging tubes caused by the unilateral arrangement of the lifting bracket, and the difficult control of the scale by manual labor, which easily leads to depth deviation of the transducers.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A seismic strength detection device for bridge foundation piles, including a lifting bracket and transducer cable wires. At a position where one end of the transducer cable wire is far from the lifting bracket, there is a support component for assisting in adjusting the horizontal position of the acoustic logging tube. The support component is connected to the transducer cable wire; a cable control component for controlling the routing of the transducer cable wire, and the cable control component is connected to the support component.

[0006] Optionally, the support component includes a vertical sleeve sleeved on one end of the transducer cable wire. A second support plate is clamped at the bottom of the vertical sleeve. A spring is fixedly connected to the bottom center of the second support plate. The bottom of the spring is rotationally connected to a first support plate. Uniformly distributed positioning grooves and second insertion holes are respectively formed through both ends of the first support plate and the second support plate. Lifting machines are fixedly connected to the bottoms of both ends of the first support plate and the second support plate. A lifting column is fixedly connected to the top center of the second support plate, and the cable control component is fixedly connected to the top of the lifting column.

[0007] Optionally, the outer contour of the second support plate is in a "ji" shape, and the projected outer contour dimensions of the second support plate and the first support plate are the same.

[0008] Optionally, symmetrically distributed first sliding grooves are formed through both sides of the second support plate near the spring. First limit pins are slidably connected inside the first sliding grooves, and the outer contour dimensions of the first sliding grooves are adapted to the inner wall dimensions of the first limit pins.

[0009] Optionally, a first insertion hole is formed through the top of the second support plate near the spring. A second limit pin is inserted into the first insertion hole, and the outer contour dimensions of the second limit pin are adapted to the inner wall dimensions of the first insertion hole.

[0010] Optionally, the first support plate has symmetrically distributed second insertion holes on both sides corresponding to the positions of the first limiting pin, and the inner wall size of the second insertion hole is adapted to the outer contour size of the first limiting pin.

[0011] Optionally, the lifting column has evenly distributed first insertion holes, and the inner wall diameter of the first insertion hole is the same as the inner wall diameter of the second insertion hole.

[0012] Optionally, a rotating block is inserted into both the second socket and the first socket, and the free end of the rotating block is rotatably connected to the same connecting rod, with pulleys fixedly connected to both ends of the connecting rod.

[0013] Optionally, the control cable assembly includes a plug fixedly connected to the top of the lifting column, with evenly distributed blocking blocks snapped onto the plug, an installation block snapped onto the center of the plug, a first wire groove symmetrically distributed fixedly connected to the top of the installation block, a fixing block fixedly connected to the bottom of the installation block, a second wire groove symmetrically distributed fixedly connected to the fixing block, and a positioning clip sleeved on the transducer cable near the fixing block.

[0014] Optionally, the plug is provided with a second groove at the position of each of the multiple blocking blocks, and symmetrically distributed sliders are fixedly connected to both sides of the blocking block. The outer contour size of the slider is adapted to the inner wall size of the second groove.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up support components and control components, the support components can be adapted to foundation piles of different sizes and uneven testing sites. With the help of multi-point horizontal adjustment, it can be conveniently ensured that the transducers are kept on the same horizontal plane. The control components can symmetrically lay out four cables and unify their length to the lifting bracket, so as to achieve precise synchronization of transducer depth, eliminate the depth deviation of traditional wiring, and quickly put the transducers on the same testing plane, which meets the testing requirements of the acoustic transmission method.

[0016] By setting up a first support plate and a second support plate in conjunction, and with the compression / extension of the spring and the locking structure of the first and second limit pins, it can quickly switch to a cross-shaped stable state to meet the equipment's working needs or to be stacked and stored, saving space and facilitating transportation and retrieval. In addition, with the lifting platforms at both ends, it can adapt to uneven ground, better maintain the level of the first and second support plates, and improve the ease of operation and site adaptability.

[0017] By setting up a rotating block and connecting rod, different diameter foundation piles can be adapted by the snap-fit ​​between the second and first sockets. The pulleys at both ends of the connecting rod can precisely limit the movement of the transducer cable and prevent cable deviation. The four rows of first sockets correspond to the two ends of the first and second support plates that are crossed. The symmetrical arrangement of the connecting rods ensures that the movement paths of the four transducer cables are consistent, ensuring synchronous transducer depth. The snap-fit ​​design of the rotating block with the first and second sockets makes the whole device easy to disassemble and store, greatly improving the equipment's versatility, adaptability and ease of operation.

[0018] By setting up the first and second cable slots in combination, the bending part of the second cable slot precisely offsets the length difference of the cable routing, ensuring that the distance from the four transducer cables to the fixing block is completely consistent. This guarantees the synchronous depth of the transducers from the source. Combined with the limiting effect of the positioning clamp and the fixing block, it can not only stabilize the cable position, but also flexibly slide and adjust under external force to adapt to different testing needs. At the same time, the combination of the first and second cable slots, along with the slot structure for the plug, further standardizes the cable routing and prevents side slippage, greatly improving the accuracy, stability and convenience of the testing operation.

[0028] like Figures 1 to 12 As shown, an embodiment of the present invention provides a bridge foundation pile seismic strength testing device, including a lifting support 1 and a transducer cable 2. A support assembly is provided at one end of the transducer cable 2 away from the lifting support 1. The support assembly is used to assist in adjusting the horizontal position of the acoustic logging tube. The support assembly is connected to the transducer cable 2 (e.g., ...). Figures 1 to 2 (As shown); control line assembly, the control line assembly is used to control the routing of transducer cable 2, the control line assembly is connected to the support assembly. The bridge foundation pile seismic strength testing equipment provided in this application is suitable for testing the seismic strength of foundation piles using the acoustic transmission method. The working principle of the acoustic transmission method is disclosed as prior art and will not be described in detail. In actual products, ultrasonic waves are used to "see through" the concrete of the pile body. During testing, transmitting and receiving transducers are placed in the acoustic tube pre-embedded in the foundation pile. The transducer emits ultrasonic waves that pass through the concrete of the pile body, and the other end receives them. By analyzing the propagation speed, amplitude, and frequency changes of the ultrasonic waves, it is determined whether the concrete is dense and whether there are defects such as voids, cracks, and mud inclusions. Areas with slow speed and weak signal are likely to be problematic areas.

[0029] By setting up support components and control components, the support components can be adapted to foundation piles of different sizes and uneven testing sites. With the help of multi-point horizontal adjustment, it can be conveniently ensured that the transducers are kept on the same horizontal plane. The control components can symmetrically lay out four cables and unify their length to the lifting bracket 1, so as to achieve precise synchronization of transducer depth, eliminate the depth deviation of traditional wiring, and quickly put the transducers on the same testing plane, which meets the testing requirements of the acoustic transmission method.

[0030] As one implementation method in this embodiment, such as Figures 1 to 12 As shown, the support assembly includes a vertical sleeve 28 fitted onto one end of the transducer cable 2. A second support plate 5 is snapped onto the bottom of the vertical sleeve 28. A spring 10 is fixedly connected to the bottom center of the second support plate 5. A first support plate 4 is rotatably connected to the bottom of the spring 10. The outer contour of the second support plate 5 is "U"-shaped. The projected outer contour dimensions of the second support plate 5 and the first support plate 4 are consistent. Symmetrically distributed first sliding grooves 11 are provided on both sides of the second support plate 5 near the spring 10. A first limiting pin 12 is slidably connected inside the first sliding groove 11. The outer contour dimensions of the first sliding groove 11 are adapted to the inner wall dimensions of the first limiting pin 12. A first insertion hole 13 is provided on the top of the second support plate 5 near the spring 10. A second limiting pin 14 is inserted into the first insertion hole 13. The outer contour dimensions of the second limiting pin 14 are consistent with the inner wall dimensions of the first insertion hole 13. The first support plate 4 has symmetrically distributed second insertion holes 15 on both sides corresponding to the positions of the first limiting pins 12. The inner wall size of the second insertion holes 15 is adapted to the outer contour size of the first limiting pins 12. The first support plate 4 and the second support plate 5 have uniformly distributed positioning grooves 8 and second insertion holes 9 through both ends. The bottom ends of the first support plate 4 and the second support plate 5 are fixedly connected to the lifting mechanism 3. The top of the center of the second support plate 5 is fixedly connected to the lifting column 6. The top of the lifting column 6 is fixedly connected to the control wire assembly. The lifting column 6 has uniformly distributed first insertion holes 7. The inner wall diameter of the first insertion hole 7 is the same as the inner wall diameter of the second insertion hole 9. Rotating blocks 16 are inserted into both the second insertion hole 9 and the first insertion hole 7. The free end of the rotating block 16 is rotatably connected to the same connecting rod 17. Pulleys 18 are fixedly connected to both ends of the connecting rod 17.

[0031] Specifically, the first support plate 4 and the second support plate 5 are connected together by a spring 10. The center of the second support plate 5 protrudes upward. When the spring 10 is compressed by an external force, it is compressed between the first support plate 4 and the second support plate 5. At this time, the first support plate 4 and the second support plate 5 are in a cross-shaped relationship. The first limiting pin 12 slides in the first groove 11 to a position close to the first support plate 4. The first limiting pin 12 is in a horizontal state, and it engages with the second insertion hole 15. Then, the second limiting pin 14 is pressed downward, so that it is inserted into the first insertion hole 13. At this time, with the cooperation of the first limiting pin 12 and the second limiting pin 14, the cross-shaped relationship between the first support plate 4 and the second support plate 5 remains stable (e.g., Figures 1 to 8 As shown), spring 10 is in a compressed state. When the equipment is finished using, the second limiting pin 14 can be lifted upwards to facilitate the separation of the first limiting pin 12 from the second insertion hole 15. In this way, spring 10 is relieved of external pressure and is in a naturally extended state. At this time, the first support plate 4 is located below the second support plate 5. Rotating the first support plate 4 can store the first support plate 4 and the second support plate 5 in a stacked state (as shown). Figures 9 to 10 As shown), it is convenient to pick up and transport, effectively saving space. In addition, the bottom ends of both ends of the first support plate 4 and the second support plate 5 are fixedly connected to the lifting mechanism 3 (as shown). Figures 1 to 5 As shown, the lifting platform 3 is a manual screw jack. By manually operating the crank handle, the screw is rotated and engages with the internal nut. Since the nut is restricted by the structure and cannot rotate, it will move linearly along the screw, thereby driving the connected first support plate 4 and second support plate 5 to achieve lifting and lowering. Reverse cranking can control descent. Through the helical transmission between the screw and the nut, the rotational motion is converted into linear lifting and lowering motion. The working principle of the manual screw jack 3 is disclosed as prior art and will not be elaborated further. By using the multi-point lifting platform 3, it can better adapt to uneven surveying sites and facilitate maintaining the horizontal state of the first support plate 4 and the second support plate 5.

[0032] By setting up the first support plate 4 and the second support plate 5 in conjunction, and with the compression / extension of the spring 10 and the locking structure of the first limit pin 12 and the second limit pin 14, it can be quickly switched to a cross-shaped stable state to meet the working needs of the equipment or to be stacked and stored, saving space and facilitating transportation and retrieval. In addition, with the lifting platforms 3 at both ends, it can adapt to uneven sites, better maintain the level of the first support plate 4 and the second support plate 5, and improve the ease of operation and site adaptability.

[0033] Furthermore, both the first support plate 4 and the second support plate 5 are provided with positioning grooves 8 and second insertion holes 9, and the lifting column 6 is provided with uniformly spaced first insertion holes 7. The rotating block 16 can be engaged with the second insertion hole 9 and the first insertion hole 7 by utilizing the cooperation of the second insertion hole 9 and the first insertion hole 7. The rotating block 16 and the connecting rod 17 are rotatably connected, which can adapt to foundation piles of different diameters. Using the pulleys 18 provided at both ends of the connecting rod 17, after the transducer cable 2 is inserted into the second insertion hole 9 through the vertical sleeve 28, the transducer cable 2 passes above the pulley 18 at the bottom of the connecting rod 17, and then below the pulley 18 at the top of the connecting rod 17. The movement of the transducer cable 2 is limited by the cooperation of the connecting rod 17 and the pulleys 18 (e.g., ...). Figures 1 to 5 As shown), the first insertion hole 7 on the lifting column 6 has four rows, corresponding to the two ends of the first support plate 4 and the second support plate 5 in the cross-shaped state (as shown). Figure 7 As shown, by symmetrically arranging the connecting rods 17, the routing paths of the four transducer cables 2 are kept consistent. The rotating block 16 is engaged with the first socket 7 and the second socket 9 for easy disassembly and storage. In addition, the top of the elevator 3 is also fixedly connected to the first support plate 4 and the second support plate 5 by means of nuts. If necessary, the elevator 3 can also be easily disassembled.

[0034] By setting up the rotating block 16 and the connecting rod 17, different diameter foundation piles can be adapted by the snap-fit ​​between the second socket 9 and the first socket 7. The pulleys 18 at both ends of the connecting rod 17 can accurately limit the movement of the transducer cable 2 and prevent the cable from deviating. The four rows of first sockets 7 correspond to the two ends of the cross-shaped first support plate 4 and the second support plate 5. The symmetrical arrangement of the connecting rod 17 ensures that the movement paths of the four transducer cables 2 are consistent, ensuring that the transducer depth is synchronized. The snap-fit ​​design of the rotating block 16 with the first socket 7 and the second socket 9 makes the whole unit easy to disassemble and store, greatly improving the equipment's versatility, adaptability and ease of operation.

[0035] As one implementation method in this embodiment, such as Figures 1 to 12 As shown, the control line assembly includes a plug 19 fixedly connected to the top of the lifting column 6. Evenly distributed blocking blocks 20 are snapped onto the plug 19. A mounting block 23 is snapped onto the center of the plug 19. A symmetrically distributed first wire groove 24 is fixedly connected to the top of the mounting block 23. A fixing block 26 is fixedly connected to the bottom of the mounting block 23. A symmetrically distributed second wire groove 25 is fixedly connected to the fixing block 26. A positioning clip 27 is sleeved on the transducer cable 2 near the fixing block 26. A second sliding groove 21 is provided on the plug 19 corresponding to the positions of most of the blocking blocks 20. Symmetrically distributed sliders 22 are fixedly connected to both sides of the blocking blocks 20. The outer contour dimensions of the sliders 22 are adapted to the inner wall dimensions of the second sliding grooves 21.

[0036] Furthermore, a plug 19 is fixedly connected to the top of the lifting column 6. The plug 19 has grooves at both ends corresponding to the first support plate 4 and the second support plate 5 for engaging the blocking block 20. Symmetrically arranged second sliding grooves 21 are provided on the grooves, which are adapted to the slider 22, facilitating the engagement or disengagement of the blocking block 20 and the plug 19. The transducer cable 2 passes through the grooves on the plug 19, and the blocking block 20 prevents the transducer cable 2 from slipping off the side. A mounting block 23 is connected to the center of the plug 19. Symmetrically distributed first wire grooves 24 are fixedly connected to the mounting block 23. Symmetrically distributed second wire grooves 25 are provided on both sides of the first wire grooves 24, and the first wire grooves 24 and second wire grooves 25 are fixed together by a fixing block 26 (e.g., ...). Figure 12 As shown in the diagram, since the lifting bracket 1 is located on one side of the plug 19, and preferably the lifting bracket 1 can be located on the extension line of the center between adjacent first cable trays 24, and since the distance of the transducer cable 2 from the two blocking blocks 20 away from the lifting bracket 1 to the fixed block 26 is greater than the distance of the transducer cable 2 from the two blocking blocks 20 close to the lifting bracket 1 to the fixed block 26, a bend is provided at one end of the second cable tray 25 away from the fixed block 26, in order to make the distance of the transducer cable 2 from the inside of the four blocking blocks 20 to the fixed block 26 equal. Furthermore, a positioning clip 27 is sleeved on the outer wall of the transducer cable 2, and the positioning clip 27 is located close to the fixing block 26. The outer contour dimension of the positioning clip 27 is larger than the inner wall dimension of the fixing block 26. In order to use the cooperation between the positioning clip 27 and the fixing block 26 to limit the position of the transducer cable 2 and facilitate the adjustment of the position of the transducer cable 2, the positioning clip 27 is a constant tension clip, which can maintain a continuous and stable clamping force through the elastic adaptive change of its own structure. The positioning clip 27 can slide on the transducer cable 2 under the intervention of external force, which facilitates the adjustment of the position of the transducer cable 2.

[0037] By setting up the first cable groove 24 and the second cable groove 25 in cooperation, the bending part of the second cable groove 25 is used to accurately offset the length difference of the cable routing, so that the distance from the four transducer cables 2 to the fixing block 26 is completely consistent, ensuring the transducer depth synchronization from the source. With the limiting effect of the positioning clamp 27 and the fixing block 26, the cable position can be stabilized and can be flexibly adjusted under external force to adapt to different testing needs. At the same time, the combination of the first cable groove 24 and the second cable groove 25, together with the groove structure of the plug 19, further standardizes the cable routing, prevents side slippage, and greatly improves the accuracy, stability and convenience of the testing operation.

[0038] The working principle of the technical solution provided by this invention is as follows: In use, depending on the size of the foundation pile and the site environment, firstly, unfold the first support plate 4 and the second support plate 5, placing them in a cross-shaped state. When the spring 10 is compressed by external force, it is compressed between the first support plate 4 and the second support plate 5, making the first support plate 4 and the second support plate 5 form a cross-shaped relationship. The first limiting pin 12 slides in the first groove 11 to a position close to the first support plate 4, and the first limiting pin 12 is in a horizontal state. The first limiting pin 12 is then engaged with the second insertion hole 15. Next, the second limiting pin 14 is pressed down, so that the second limiting pin 14 is inserted into the first insertion hole 13. At this time, the first limiting pin 12... With the cooperation of the second limiting pin 14, the cross relationship between the first support plate 4 and the second support plate 5 remains stable, and the spring 10 is in a compressed state. Then, the lifting platform 3 is adjusted in sequence so that the first support plate 4 and the second support plate 5 are in a horizontal state. Then, based on the diameter of the four sonic logging tubes placed on the foundation pile, the position of the connecting rod 17 is adjusted. Since the first support plate 4 and the second support plate 5 are both provided with positioning grooves 8 and second insertion holes 9, and the lifting column 6 is provided with uniform first insertion holes 7, the rotating block 16 can be engaged with the second insertion hole 9 and the first insertion hole 7 by using the cooperation of the second insertion hole 9 and the first insertion hole 7. The rotating block 16 and the connecting rod 17 are rotatably connected, which can... Adapt to foundation piles of different diameters, then separate the blocking block 20 from the plug 19 to facilitate the insertion of the transducer cable 2. Position the lifting bracket 1 on the extension line of the center of the fixing block 26. After all equipment is in place, insert the end of the transducer cable 2 with the transducer inside the vertical sleeve 28, then pass it through the pulley 18, plug 19, and the first or second cable groove 24. The synchronous lifting and lowering of the transducer cable 2 is controlled by the transducer cable 2. The position of the positioning clamp 27 on the transducer cable 2 is used to ensure that the transducers on the four transducer cables 2 are at the same horizontal level. Then, the transducer cable... The other end of cable 2 is connected to the electrical control system for depth inspection. Then, following the standard operation of the acoustic transmission method, the transmitting / receiving transducer is placed into the acoustic tube, water is injected for coupling, and the transducer is kept synchronized through the transducer cable 2. Subsequent work such as segmented testing, data processing, and strength assessment is then carried out. This device can be adapted to piles of different sizes and uneven testing sites. With the help of multi-point horizontal adjustment, it can easily ensure that the transducers are kept on the same horizontal plane. The four cables can also be symmetrically laid out and their lengths to the lifting bracket 1 can be unified to achieve precise synchronization of transducer depth, eliminate the depth deviation of traditional wiring, and quickly put the transducers on the same testing plane, which meets the testing requirements of the acoustic transmission method.
