Technical Field

[0001] This utility model relates to the field of pipe piles, and more particularly to the field of testing the concrete strength of pipe piles. Specifically, it refers to a device for automatically testing the concrete strength of pipe piles at multiple points using a rebound hammer. Background Technology

[0002] Manually using handheld rebound hammers to test the concrete strength of pipe piles is inefficient, and the results vary from test to test, requiring data to be handwritten or entered. Furthermore, manual inspections on the production line are generally done by sampling, which cannot guarantee the quality of every single pipe pile. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for automatically multi-point testing of concrete strength of pipe piles using a rebound hammer, which is simple in structure, accurate in measurement, and has a wide range of applications.

[0004] To achieve the above objectives, the present invention provides a device for automatically testing the concrete strength of pipe piles at multiple points using a rebound hammer, as follows:

[0005] The device for automatically testing the concrete strength of pipe piles at multiple points using a rebound hammer is characterized by the following: the device includes a pipe pile support structure and a strength testing structure. The strength testing structure includes a rebound hammer and a Y-motion component. Both the pipe pile support structure and the strength testing structure are installed on the ground. The rebound hammer is mounted on the Y-motion component, which supports vertical movement. The pipe pile is placed above the pipe pile support structure, and the strength testing structure is located below the pipe pile. The rebound hammer moves vertically via the Y-motion component and contacts the outer layer of concrete of the pipe pile.

[0006] Preferably, the Y-movement component includes a vertical slide rail and a guide cylinder. The vertical slide rail is vertically installed on the ground, the rebound spring is installed on the guide cylinder, and the guide cylinder is installed in the vertical slide rail. The guide cylinder moves up and down in the vertical slide rail, driving the rebound spring to move up and down.

[0007] Preferably, the strength detection structure further includes an X-movement component, which includes an X-movement motor, a slide rail, a lead screw, a nut, and a moving plate. The slide rail is fixed to the ground, the lead screw is installed inside the slide rail, and both ends of the lead screw are connected to the inner walls of the slide rail on both sides. The X-movement motor is installed on the side of the slide rail and is connected to the lead screw. The outer surface of the lead screw has a helix. The nut is installed on the lead screw and located in the slide rail, and the nut meshes with the helix of the lead screw. The moving plate is installed above the nut, and the Y-movement component is installed above the moving plate. The X-movement motor drives the lead screw to rotate, causing the nut to move along the helix of the slide rail, and also causing the Y-movement component on the moving plate to move.

[0008] Preferably, the pipe pile support structure includes a lifting platform, a power unit, a reducer, a drive sprocket, a chain, and idlers. The idlers include a drive idler and a driven idler, which are mounted side-by-side on the upper surface of the lifting platform. The pipe pile is placed between the drive idler and the driven idler. The power unit and the reducer are both mounted on the side of the lifting platform. The reducer is connected to the power unit. The drive sprocket is mounted on the reducer. Gears are mounted on the side of the drive idler. The chain wraps around the gears and drive sprocket of the drive idler. The power unit drives the reducer and rotates the drive sprocket, which in turn rotates the drive idler via the chain, and the pipe pile moves via friction.

[0009] Preferably, the pipe pile support structure further includes a guide rod, which is installed inside the lifting platform and located below the active and driven rollers. The guide rod supports vertical lifting, and when the guide rod rises, it drives the rollers to rise.

[0010] Preferably, the pipe pile support structure further includes a conveying structure, which is installed above the lifting platform. The conveying structure supports forward movement, is in close contact with the pipe pile, and drives the pipe pile forward when the conveying structure moves forward.

[0011] This device, which enables automatic multi-point testing of concrete strength in pipe piles using a rebound hammer, significantly improves testing efficiency by changing the manual, single-point testing mode. Through the movement and rotation of the pipe pile or the rebound hammer, automatic multi-point rapid testing is achieved, greatly shortening testing time and aligning with the continuous production rhythm of the production line, thus significantly improving overall production efficiency. In terms of accuracy, the high-strength digital display rebound hammer, combined with stable mechanical transmission, avoids testing errors caused by varying force and angle during manual operation. Automatic data acquisition and transmission eliminate handwritten input errors, ensuring data accuracy and reliability. It also assists in optimizing and adjusting the production process. Regarding flexibility and scalability, the testing method can be adjusted according to actual needs, and the number of rebound hammers can be increased or decreased to adapt to different working conditions, making it widely applicable.

[0040] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.

[0041] This utility model discloses a device for automatically testing the concrete strength of pipe piles at multiple points using a rebound hammer. The device includes a pipe pile support structure and a strength testing structure. The strength testing structure comprises a rebound hammer 2 and a Y-motion component 3. Both the pipe pile support structure and the strength testing structure are installed on the ground. The rebound hammer 2 is mounted on the Y-motion component 3, which supports vertical movement. The pipe pile is placed above the pipe pile support structure, and the strength testing structure is located below the pipe pile. The rebound hammer 2 moves vertically via the Y-motion component 3 and contacts the outer layer of concrete of the pipe pile 1.

[0042] In a preferred embodiment of the present invention, the Y-moving component 3 includes a vertical slide rail and a guide cylinder. The vertical slide rail is vertically installed on the ground, and the rebound device 2 is installed on the guide cylinder. The guide cylinder is installed in the vertical slide rail, and the guide cylinder moves up and down in the vertical slide rail, thereby driving the rebound device 2 to move up and down.

[0043] In a preferred embodiment of this utility model, the strength detection structure further includes an X-moving component 6, which includes an X-moving motor, a slide rail, a lead screw, a nut, and a moving plate. The slide rail is fixed to the ground, the lead screw is installed inside the slide rail, and both ends of the lead screw are connected to the inner walls of both sides of the slide rail. The X-moving motor is installed on the side of the slide rail and is connected to the lead screw. The outer surface of the lead screw has a helical line. The nut is installed on the lead screw and located in the slide rail, and the nut meshes with the helical line of the lead screw. The moving plate is installed above the nut, and the Y-moving component 3 is installed above the moving plate. The X-moving motor drives the lead screw to rotate, causing the nut to move along the slide rail along the helical line, and also causing the Y-moving component 3 on the moving plate to move.

[0044] In a preferred embodiment of this utility model, the pipe pile support structure includes a lifting platform, a power component 5, a reducer, a drive sprocket, a chain, and an idler roller 4. The idler roller 4 includes a drive idler roller and a driven idler roller, which are installed side by side on the upper surface of the lifting platform. The pipe pile is placed between the drive idler roller and the driven idler roller. The power component 5 and the reducer are both installed on the side of the lifting platform. The reducer is connected to the power component 5. The drive sprocket is installed on the reducer. A gear is installed on the side of the drive idler roller. The chain wraps around the gear and the drive sprocket of the drive idler roller. The power component 5 drives the reducer and drives the drive sprocket to rotate. The chain drives the drive idler roller to rotate, and the friction drives the pipe pile to move.

[0045] In a preferred embodiment of the present invention, the pipe pile support structure further includes a guide rod, which is installed inside the lifting platform and located below the active roller and the driven roller. The guide rod supports vertical lifting, and when the guide rod is raised, it drives the roller to rise.

[0046] In a preferred embodiment of the present invention, the pipe pile support structure further includes a conveying structure, which is installed above the lifting platform. The conveying structure supports forward movement, is in close contact with the pipe pile, and drives the pipe pile forward when the conveying structure moves forward.

[0047] In a specific embodiment of this utility model, a high-strength digital rebound hammer 2 is used to automatically detect the concrete strength of the pipe pile 1, allowing for multi-point testing of each pipe pile 1. The high-strength rebound hammer 2 moves its actuator to contact the concrete surface of the pipe pile 1, detecting the concrete strength. The detected values ​​can be viewed in real-time via Bluetooth, wireless, or wired connections, and the data can also be saved to a server or storage device. The rebound hammer 2 can also be non-digital. Multi-point testing can involve detecting one location point, then moving or rotating the pipe pile 1 a certain position before the rebound hammer 2 tests again; alternatively, the pipe pile 1 can remain stationary while the rebound hammer 2 moves to multiple locations to perform multiple tests. This method of automatically detecting concrete strength at multiple points using the rebound hammer 2 can be applied not only to the pipe pile industry but also to related industries.

[0048] The rebound hammer 2 automatically performs multi-point testing of the concrete strength of the pipe pile 1, which can ensure the quality of each pipe pile 1 and reduce the intensity of manual operation. At the same time, it provides real-time feedback on the changes in the concrete strength of the pipe pile 1 and saves the test data for tracking.

[0049] Pipe pile 1 rests on roller 4. Rebound hammer 2 moves via Y-axis movement component 3 to contact the outer layer of concrete of pipe pile 1, measuring the concrete strength and displaying the data to the terminal. After rebound hammer 2 returns to its initial position, power component 5 rotates pipe pile 1 by a certain angle and stops, allowing rebound hammer 2 to contact pipe pile 1 again to measure data. This process can be repeated automatically to measure multiple sets of values.

[0050] If roller 4 is replaced with a conveyor, the concrete strength of pipe pile 1 is tested once, and then moved forward a certain distance before testing again.

[0051] If the pipe pile 1 remains stationary, an X-moving component 6 can be added to the Y-moving component 3, and the rebound hammer 2 can also detect the concrete strength at different locations of the pipe pile 1.

[0052] In special circumstances, multiple rebound hammers can be installed for testing.

[0053] The rebound hammer 2 (or digital display) automatically performs multi-point testing of the concrete strength of the pipe pile 1 and displays the test values ​​in real time. The values ​​can be transmitted, stored, and viewed via Bluetooth, wireless, or wired connection.

[0054] When the rebound hammer 2 is testing multiple points, the pipe pile 1 (workpiece) can rotate or move, or the pipe pile 1 (workpiece) can remain stationary while the rebound hammer 2 moves at multiple points to test the concrete strength at multiple locations on the pipe pile 1.

[0055] If there are special requirements, multiple rebound hammers 2 can be distributed in multiple locations to test the concrete strength of the pipe pile 1 (workpiece).

[0056] The X-axis moving assembly enables the guide cylinder to be used in automated production. The X-axis moving motor is the actuator, the lead screw is the transmission component, and the slide rail is the guide component. The rotation of the X-axis moving motor drives the lead screw to rotate, and the nut is restricted by the slide rail to move only along the spiral line of the lead screw.

[0057] The motor drives the drive sprocket via a reducer, and the chain moves accordingly, thus driving the drive roller. If the pipe pile can be directly (hoisted) placed on the drive roller, the drive roller drives the pipe pile through friction. If the pipe pile can only be moved above the roller via a conveyor line, a hydraulic cylinder or lifting platform (electric) below the roller raises the roller to contact the pipe pile, thereby causing the pipe pile to rotate through the rotation of the roller.
