Description

Technical Field

[0001] This application relates to the field of concrete pipe pile testing technology, and in particular to a PHC concrete pipe pile crack resistance testing device. Background Technology

[0002] PHC concrete pipe piles, also known as prestressed high-strength concrete pipe piles, are hollow cylindrical precast concrete components made using a pre-tensioned prestressed centrifugal molding process and then cured under high-pressure steam.

[0003] The published patent document CN118547730A discloses a PHC concrete pipe pile crack resistance testing device, which includes a bottom support, a plug mechanism, a radial adjustment mechanism, an axial adjustment mechanism, and a clamping mechanism. The plug mechanism includes two end caps; the radial adjustment mechanism includes a sliding ring and a ring frame, with the ring frame fixed to the bottom support and the sliding ring rotatably mounted on the ring frame; the axial adjustment mechanism includes a semi-circular slide rail, a track seat, a slider, and a locking device, with the track seat fixed to both ends of the semi-circular slide rail and the top of the sliding ring fixedly connected to the track seat; the clamping mechanism includes a clamping device and a cylinder, with the clamping device clamping onto the pipe pile and the cylinder fixed to the slider, the front end of the cylinder hinged to the clamping device. The orientation of the cylinder on the clamping mechanism is adjusted by the radial and axial adjustment mechanisms, thereby applying pressure to the pipe pile in different directions, and simultaneously applying axial pressure and tension to the pipe pile.

[0004] In actual use, the locking knob needs to be manually adjusted before the cylinder position can be adjusted, which requires a large amount of manual labor and has low efficiency in inspecting pipe piles.

[0005] Therefore, this application provides a PHC concrete pipe pile crack resistance testing device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this application provides a PHC concrete pipe pile crack resistance testing device, which overcomes the deficiencies of existing technologies and aims to solve the problem that in actual use of the above devices, the locking knob needs to be manually adjusted before the cylinder position can be adjusted, resulting in a large amount of manual labor and low testing efficiency for pipe piles.

[0007] To achieve the above objectives, this application provides the following technical solution: a PHC concrete pipe pile crack resistance testing device, comprising a left half support, a right half support, and a concrete pipe pile. A clamping mechanism is installed on the top of the left half support, and the concrete pipe pile is installed between the left half support and the clamping mechanism through the clamping mechanism. An axial adjustment mechanism is provided around the periphery of the concrete pipe pile, and a radial adjustment mechanism is provided above the left half support. The radial adjustment mechanism includes a servo motor, which is fixedly installed on the top of the left half support. A driving bevel gear is fixedly installed at the output end of the servo motor. A vertical plate is fixedly installed on the top of the left half support on one side of the servo motor. A rotating shaft is rotatably connected to one side of the vertical plate. A driven bevel gear is fixedly installed on the outer surface of the rotating shaft, and the driven bevel gear meshes with the driving bevel gear. A fixing block is fixedly installed on the outer surface of the rotating shaft on one side of the driven bevel gear. A second hydraulic rod is fixedly installed on the top of the fixing block, and the telescopic end of the second hydraulic rod is fixedly installed at the bottom end of the axial adjustment mechanism.

[0008] By adopting the above technical solution, the concrete pipe pile is clamped and fixed by the clamping mechanism, and the pressure block is used to conduct crack resistance tests on the concrete pipe pile. The servo motor drives the active bevel gear to rotate, and the active bevel gear meshes with the driven bevel gear to drive the rotating shaft to rotate. The rotating shaft is linked to the rotation of the fixed block, and the fixed block drives the axial adjustment mechanism to rotate through the second hydraulic rod, thereby adjusting the radial position of the pressure block. This allows the pressure block to apply pressure to different radial positions of the concrete pipe pile. The axial position of the pressure block is adjusted by the axial adjustment mechanism, thereby conducting crack resistance tests on the concrete pipe pile. By controlling the servo motor to automatically adjust the radial position of the pressure block, the labor intensity of the workers is greatly reduced, while the detection efficiency of crack resistance tests on PHC concrete pipe piles is improved.

[0009] As a preferred embodiment of this application, the axial adjustment mechanism includes a rectangular frame, which is fixedly installed at the telescopic end of the second hydraulic rod. A reciprocating motor is fixedly installed inside the rectangular frame, and a screw is fixedly installed at the output end of the reciprocating motor. A moving block is threaded onto the outer surface of the screw, and a slider is fixedly installed at the bottom end of the moving block. A groove matching the slider is provided at the bottom of the rectangular frame, and a rectangular plate is fixedly installed at the bottom end of the slider. A first hydraulic rod is fixedly installed at the bottom end of the rectangular plate, and a pressure block is fixedly installed at the telescopic end of the first hydraulic rod.

[0010] By adopting the above technical solution, the first hydraulic rod extends to drive the pressure block to apply pressure to the concrete pipe pile. The reciprocating motor drives the screw to rotate, and the moving block moves under the action of the screw, thereby driving the pressure block to move axially. This allows the pressure block to apply pressure to different axial positions of the concrete pipe pile, improving the automation level of the pressure block's axial movement and further improving the detection efficiency of the PHC concrete pipe pile crack resistance test.

[0011] As a preferred embodiment of this application, the clamping mechanism includes a support block, which is fixedly installed on the top of the left half-support. A left-side support frame is fixedly installed on the top of the support block. The side of the rotating shaft away from the upright plate is rotatably connected to the side wall of the left-side support frame. A left-side locking block is fixedly installed on the side of the left-side support frame away from the rotating shaft. A right-side support frame is fixedly installed on the top of the right half-support. A guide mechanism is installed on the top of the right-side support frame. An electric push rod is installed on one side of the guide mechanism. An annular plate is fixedly installed on the telescopic end of the electric push rod. A right-side locking block is fixedly installed on one side of the annular plate. The left-side locking block and the right-side locking block are respectively inserted into both ends of the concrete pipe pile.

[0012] By adopting the above technical solution, one end of the concrete pipe pile is clamped on one side of the left clamping block, and then the annular plate is moved by the electric push rod, so that the right clamping block is clamped into the other end of the concrete pipe pile. The left and right clamping blocks are respectively inserted into the two ends of the concrete pipe pile, thereby clamping the concrete pipe pile and improving its practicality in use.

[0013] As a preferred embodiment of this application, a pressure sensor is fixedly installed at the bottom of the pressure block, and a display is fixedly installed on one side of the right half bracket, with the pressure sensor electrically connected to the display.

[0014] By adopting the above technical solution, the pressure applied to the concrete pipe pile by the pressure sensor is monitored in real time, and the monitoring data of the pressure sensor can be viewed on the display.

[0015] As a preferred technical solution of this application, the guiding mechanism includes a limiting sleeve, which is fixedly installed on the top of the right support frame. A connecting shaft is fixedly connected to the middle of the limiting sleeve. A guide groove is fixedly installed inside the limiting sleeve at the outer ring of the connecting shaft. A guide block is slidably connected inside the limiting sleeve at the guide groove. A third hydraulic rod is fixedly installed on the top of the guide block.

[0016] By adopting the above technical solution, when the rectangular frame rotates, the third hydraulic rod and the guide block rotate synchronously. The guide block slides in the guide groove to provide guidance and support for the rotation of the rectangular frame. At the same time, the second hydraulic rod extends and retracts according to the pipe piles with different outer diameters. When the second hydraulic rod drives the rectangular frame to move, the third hydraulic rod extends and retracts synchronously under the action of the rectangular frame, which improves the stability of the axial adjustment mechanism during adjustment.

[0017] As a preferred technical solution of this application, both the left card block and the right card block are T-shaped.

[0018] By adopting the above technical solution, and with both the left and right locking blocks being T-shaped, it is beneficial to fix pipe piles with different inner diameters.

[0019] As a preferred technical solution of this application, bearings are installed at the connection points of the rotating shaft with the upright plate and the left support frame.

[0020] By adopting the above technical solution, the smoothness of the connection between the rotating shaft and the upright plate and the left support frame is improved by the bearing, thus improving the smoothness of the rotating shaft's rotation.

[0021] As a preferred technical solution of this application, a protective cover is fixedly installed on the top of the left half bracket on the outer periphery of the radial adjustment mechanism.

[0022] By adopting the above technical solution, a protective cover is used to prevent workers from being accidentally injured when the radial adjustment mechanism is working, thus improving the safety of this device.

[0023] The beneficial effects of this application are:

[0024] 1. The concrete pipe pile is clamped and fixed by a clamping mechanism. The pressure block conducts a crack resistance test on the concrete pipe pile. By starting the servo motor, the active bevel gear is driven to rotate. The active bevel gear meshes with the driven bevel gear to drive the rotating shaft to rotate. The rotating shaft is linked to the rotation of the fixed block. The fixed block drives the axial adjustment mechanism to rotate through the second hydraulic rod, thereby adjusting the radial position of the pressure block. This allows the pressure block to apply pressure to different radial positions of the concrete pipe pile. The axial position of the pressure block is adjusted by the axial adjustment mechanism, thereby conducting a crack resistance test on the concrete pipe pile. By controlling the servo motor to automatically adjust the radial position of the pressure block, the labor intensity of the workers is greatly reduced, while improving the detection efficiency of the crack resistance test of PHC concrete pipe piles.

[0025] 2. The first hydraulic rod extends to drive the pressure block to apply pressure to the concrete pipe pile. The screw is driven to rotate by a reciprocating motor, and the moving block moves under the action of the screw, thereby driving the pressure block to move axially. This allows the pressure block to apply pressure to different axial positions of the concrete pipe pile, improving the automation level of the pressure block's axial movement and further improving the detection efficiency of the PHC concrete pipe pile crack resistance test.

[0033] The concrete pipe pile 4 is clamped and fixed by the clamping mechanism 3. The pressure block 8 applies pressure to the concrete pipe pile 4 for crack resistance testing. The servo motor 601 drives the active bevel gear 602 to rotate. The active bevel gear 602 meshes with the driven bevel gear 603, driving the rotating shaft 605 to rotate. The rotating shaft 605, in conjunction with the fixing block 607, rotates. The fixing block 607, through the second hydraulic rod 608, drives the axial adjustment mechanism 5 to rotate, thereby adjusting the radial position of the pressure block 8.

[0035] The first hydraulic rod 507 extends to drive the pressure block 8 to apply pressure to the concrete pipe pile 4. The reciprocating motor 502 drives the screw 503 to rotate, and the moving block 504 moves under the action of the thread, thereby driving the pressure block 8 to move axially. This allows the pressure block 8 to apply pressure to different axial positions of the concrete pipe pile 4, improving the automation level of the axial movement of the pressure block 8 and further improving the detection efficiency of the PHC concrete pipe pile crack resistance test.

When the rectangular frame 501 rotates, it links the third hydraulic rod 705. The 05 and guide block 704 rotate synchronously. The guide block 704 slides in the guide groove 703 to provide guidance and support for the rotation of the rectangular frame 501. At the same time, the second hydraulic rod 608 extends and retracts according to the pipe pile with different outer diameter. When the second hydraulic rod 608 drives the rectangular frame 501 to move, the third hydraulic rod 705 extends and retracts synchronously under the action of the rectangular frame 501, which improves the stability of the axial adjustment mechanism 5 during adjustment.

[0038] Working principle: The clamping mechanism 3 clamps and fixes the concrete pipe pile 4, and the pressure block 8 conducts a crack resistance test on the concrete pipe pile 4. The servo motor 601 drives the active bevel gear 602 to rotate. The active bevel gear 602 meshes with the driven bevel gear 603, driving the rotating shaft 605 to rotate. The rotating shaft 605, in conjunction with the fixing block 607, rotates. The fixing block 607, through the second hydraulic rod 608, drives the axial adjustment mechanism 5 to rotate, thereby adjusting the radial position of the pressure block 8. This allows the pressure block 8 to apply pressure to different radial positions of the concrete pipe pile 4. The axial adjustment mechanism 5 adjusts the axial position of the pressure block 8, thus conducting a crack resistance test on the concrete pipe pile 4. By controlling the servo motor 601 to automatically adjust the radial position of the pressure block 8, the labor intensity of the staff is greatly reduced, while the detection efficiency of the crack resistance test of PHC concrete pipe pile is improved. The first hydraulic rod 507 extends to drive the pressure block 8 to apply pressure to the concrete pipe pile 4. The reciprocating motor 502 drives the screw 503 to rotate, and the moving block 504 moves under the action of the thread, thereby driving the pressure block 8 to move axially. This allows the pressure block 8 to apply pressure to different axial positions of the concrete pipe pile 4, improving the automation level of the axial movement of the pressure block 8 and further improving the detection efficiency of the crack resistance test of PHC concrete pipe pile.

[0039] In this method, one end of the concrete pipe pile 4 is clamped to one side of the left clamping block 303, and then the annular plate 306 is moved by the electric push rod 305, so that the right clamping block 307 is clamped into the other end of the concrete pipe pile 4. The left clamping block 303 and the right clamping block 307 are respectively inserted into the two ends of the concrete pipe pile 4, thereby clamping the concrete pipe pile 4 and improving its practicality during use. The pressure sensor 9 monitors the pressure applied to the concrete pipe pile 4 by the pressure block 8 in real time, and the monitoring data of the pressure sensor 9 can be viewed through the display 10.

[0040] Simultaneously, when the rectangular frame 501 rotates, the third hydraulic rod 705 and the guide block 704 rotate synchronously. The guide block 704 slides in the guide groove 703 to provide guidance and support for the rotation of the rectangular frame 501. At the same time, the second hydraulic rod 608 adjusts its extension and retraction according to the pipe piles with different outer diameters. When the second hydraulic rod 608 drives the rectangular frame 501 to move, the third hydraulic rod 705 extends and retracts synchronously under the action of the rectangular frame 501, which improves the stability of the axial adjustment mechanism 5 during adjustment. Since both the left-side locking block 303 and the right-side locking block 307 are T-shaped, it is beneficial to fix pipe piles with different inner diameters.

[0041] In addition, the bearing 606 improves the smoothness of the connection between the rotating shaft 605 and the upright plate 604 and the left support frame 302 when the shaft 605 rotates, thus improving the smoothness of the rotation of the shaft 605; the protective cover 11 is used to prevent the radial adjustment mechanism 6 from accidentally injuring the staff when it is working, thus improving the safety of the device.
