Description

Technical Field

[0001] This application relates to the technical field of pile driving tests, and more particularly, to a pile driving test system. Background Art

[0002] In China, the offshore wind power foundation structure mostly adopts the single-pile foundation form. This structural design is simple and the installation process is mature, which has become the mainstream choice in offshore wind power projects. However, with the continuous progress of offshore wind power technology, the application of large-diameter single piles is becoming increasingly widespread, which poses higher requirements for related test equipment and technologies.

[0003] Currently, the existing pile driving testing machines or test devices have relatively simple structures and obvious limitations. For example, a pile driving testing machine usually sets a collar under the pile hammer, and the collar is used to sleeve outside the pile body to keep the pile body stable. However, since the collar is located under the pile hammer, if the pile body needs to be hoisted into the collar, the pile hammer and other related components need to be removed first. After the pile body is hoisted, the pile hammer and other components need to be restored. This not only makes the operation complex but also affects the test efficiency. Summary of the Invention

[0004] At least one embodiment of this application provides a pile driving test system, which can simplify the operation during hoisting the pile body and improve the test efficiency.

[0005] An embodiment of this application provides a pile driving test system, including:

[0011] In an optional embodiment, a guiding track is arranged on the top of the bench, and guiding sliders are arranged on the bottom of the moving platform. The guiding sliders are slidably matched with the guiding track.

[0012] In an alternative embodiment, the guiding slider is an electric slider.

[0013] In an alternative embodiment, the lifting mechanism includes a support frame, an electromagnet, and a lifting motor. The support frame is disposed on the bench. The electromagnet and the lifting motor are respectively located on both sides of the support frame. The electromagnet is used to adsorb the pile hammer when energized. The lifting motor is connected to the electromagnet through a cable, and the lifting motor is used to wind up the cable so that the electromagnet drives the pile hammer to rise.

[0014] In an alternative embodiment, the lifting mechanism further includes a guiding rod. The guiding rod is vertically disposed on one side of the support frame. The guiding rod passes through the electromagnet and the pile hammer and is in sliding fit with the electromagnet and the pile hammer.

[0015] In an alternative embodiment, the pile stabilizing assembly further includes a driving mechanism. The driving mechanism is disposed on the bench and connected to the collar. The driving mechanism is used to drive the collar to move in the X direction and the Y direction to adjust the verticality of the pile body.

[0016] In an alternative embodiment, the driving mechanism includes an X-direction electric cylinder and a Y-direction electric cylinder.

[0017] In an alternative embodiment, the pile driving test system further includes:

[0018] a detection component for detecting the verticality of the pile body;

[0019] a controller electrically connected to the detection component and the driving mechanism. The controller is used to control the driving mechanism according to the detection information of the detection component to adjust the verticality of the pile body.

[0020] The above technical solution of the present application has the following beneficial technical effects:

[0021] In the pile driving test system according to the embodiments of the present application, since the hammering component can move horizontally relative to the gantry, during the process of hoisting the pile body, the hammering component can be first moved to one side. After the pile body is hoisted into the collar, the hammering component is then moved back to its original position.

[0033] Reference Figures 1 to 3 , an embodiment of the present application provides a pile driving test system, which can simplify the operation during hoisting the pile body and improve the test efficiency.

[0034] Specifically, the pile driving test system includes:

[0035] A gantry 10;

[0036] The hammering assembly 20, the hammering assembly 20 includes a pile hammer 21 and a lifting mechanism. The pile hammer 21 is located above the pile body 1, and the lifting mechanism is arranged on the gantry 10. The lifting mechanism is used to lift the pile hammer 21 so that it can fall from a high place to hammer the pile body 1;

[0037] The pile stabilizing assembly 30, the pile stabilizing assembly 30 includes a collar 31. The collar 31 is arranged on the gantry 10 and is located below the pile hammer 21. The collar 31 is used to sleeved outside the pile body 1 to limit the inclination of the pile body 1 during the hammering process;

[0038] Wherein, the hammering assembly 20 can move horizontally relative to the gantry 10 to allow the pile body 1 to be inserted into the collar 31 from top to bottom.

[0039] In the above solution, since the hammering assembly 20 can move horizontally relative to the gantry 10, during the process of hoisting the pile body 1, the hammering assembly 20 can be moved to one side first. After the pile body 1 is hoisted into the collar 31, the hammering assembly 20 is then moved back to its original position. This setting makes it unnecessary to disassemble and assemble the pile hammer 21 and related components when hoisting the pile body 1, thereby simplifying the operation when hoisting the pile body 1 and improving the test efficiency.

[0040] In some embodiments, the gantry 10 can adopt a gantry frame. Of course, the structure of the gantry 10 is not limited to the above-discussed manner.

[0041] In some embodiments, the gantry 10 can move horizontally. For example, linear guide rails are arranged on the bottom plate, and the bottom of the gantry 10 is installed on the linear guide rails and can move along the extension direction of the linear guide rails. In this way, the driving position can be adjusted by moving the gantry 10, which is beneficial to improving the applicability of the device. Of course, in specific settings, a limiting mechanism can also be arranged at the bottom of the gantry 10 to limit the random movement of the gantry 10.

[0042] In some embodiments, the gantry 10 is provided with a moving platform 11. The moving platform 11 can move horizontally relative to the gantry 10, and the hammering assembly 20 is arranged on the moving platform 11. For example, a guiding track 12 is arranged at the top of the gantry 10, and a guiding slider 13 is arranged at the bottom of the moving platform 11. The guiding slider 13 is slidably matched with the guiding track 12. When the guiding slider 13 moves along the extension direction of the guiding track 12, the moving platform 11 can move horizontally on the gantry 10, and at the same time can drive the hammering assembly 20 to move horizontally on the gantry 10, so as to move the hammering assembly 20 when hoisting the pile body 1 to facilitate leaving a hoisting space for the pile body 1. Further, the guiding slider 13 can be an electric slider, so that no complex external transmission device is required, and the installation steps and maintenance workload can be reduced.

[0043] In some embodiments, the lifting mechanism includes a support frame 22, an electromagnet 23, and a lifting motor 24. The support frame 22 is disposed on the bench 10. The electromagnet 23 and the lifting motor 24 are respectively located on both sides of the support frame 22. The electromagnet 23 is used to adsorb the pile hammer 21 when energized. The lifting motor 24 is connected to the electromagnet 23 through a cable. The lifting motor 24 is used to wind up the cable so that the electromagnet 23 drives the pile hammer 21 to rise. During specific use, the lifting motor 24 can release the cable to lower the electromagnet 23. When the electromagnet 23 contacts the top of the pile hammer 21, the electromagnet 23 can generate suction force and adsorb the pile hammer 21 when energized. Then, the lifting motor 24 can wind up the cable so that the electromagnet 23 drives the pile hammer 21 to rise. When the pile hammer 21 rises to a set height, the electromagnet 23 is powered off, and the suction force disappears, enabling the pile hammer 21 to perform a free-fall motion to achieve hammering of the pile body 1.

[0044] In some embodiments, the lifting mechanism further includes a guiding member. The guiding member is disposed on the support frame 22 and is used to guide the electromagnet 23 and the pile hammer 21. For example, the guiding member can be a guiding rod 25. The guiding rod 25 is vertically disposed on one side of the support frame 22. The guiding rod 25 passes through the electromagnet 23 and the pile hammer 21 and is slidably engaged with the electromagnet 23 and the pile hammer 21. During specific use, the guiding member can be slidably engaged with the magnet and the pile hammer 21 during the up and down movement of the electromagnet 23 and the pile hammer 21, thereby realizing the guiding of the magnet and the pile hammer 21. This can prevent the magnet and the pile hammer 21 from moving laterally during the lifting and lowering process, affecting the hammering effect.

[0045] In some embodiments, the pile stabilizing assembly 30 further includes a driving mechanism. The driving mechanism is disposed on the bench 10 and connected to the collar 31. The driving mechanism is used to drive the collar 31 to move in the X direction and the Y direction to adjust the verticality of the pile body 1. For example, the driving mechanism includes an X-direction electric cylinder 32 and a Y-direction electric cylinder 33. The X-direction electric cylinder 32 is disposed at the bottom of the bench 10 and can move relative to the bench 10 in the Y direction. The telescopic rod of the X-direction electric cylinder 32 is connected to one end of the collar 31 in the X direction. The X-direction electric cylinder 32 is used to drive its telescopic rod to extend and retract to drive the collar 31 to move in the X direction. The Y-direction electric cylinder 33 is disposed on the extension plate 14 at the bottom of the bench 10 and can move relative to the bench 10 in the X direction. The telescopic rod of the Y-direction electric cylinder 33 is connected to one end of the collar 31 in the Y direction. The Y-direction electric cylinder 33 is used to drive its telescopic rod to extend and retract to drive the collar 31 to move in the Y direction. During specific use, when the pile body 1 is inclined in the X direction, the X-direction electric cylinder 32 can drive its telescopic rod to extend and retract to drive the collar 31 to move in the X direction, thereby adjusting the verticality of the pile body 1. At the same time, the Y-direction electric cylinder 33 can move synchronously with the collar 31, so as not to limit the movement of the collar 31 in the X direction. Or, when the pile body 1 is inclined in the Y direction, the Y-direction electric cylinder 33 can drive its telescopic rod to extend and retract to drive the collar 31 to move in the Y direction, thereby adjusting the verticality of the pile body 1. At the same time, the X-direction electric cylinder 32 can move synchronously with the collar 31, so as not to limit the movement of the collar 31 in the Y direction. In this document, the X direction is the width direction of the bench 10, and the Y direction is the length direction of the bench 10.

[0046] In some embodiments, the pile driving test system further includes a detection component. The detection component is used to detect the verticality of the pile body 1. For example, the detection component can be one or more inclination sensors. During specific use, the inclination sensor can measure the inclination angle of the pile body.

[0047] In some embodiments, the pile driving test system further includes a controller. The controller is electrically connected to the detection component and the driving mechanism. The controller is used to control the driving mechanism according to the detection information of the detection component to adjust the verticality of the pile body 1. For example, after receiving the detection information (inclination angle) of the detection component, the controller can control the X-direction electric cylinder 32 and the Y-direction electric cylinder 33 to drive the collar 31 to move, thereby adjusting the verticality of the pile body 1. Of course, during specific setting, the controller can also be electrically connected to the lifting mechanism and is used to control the lifting mechanism to stop running when the pile body 1 is inclined.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included in the protection scope of this application.
