Description

Technical Field

[0001] This application relates to the field of testing device technology, and more specifically, to a testing device for the strength of building pile foundations. Background Technology

[0002] With the increasing construction of large and super-large bridges, the application of ultra-long and long-diameter bored piles is becoming more and more widespread. After the pile foundation is poured, when the concrete age is greater than 14 days and the concrete strength reaches more than 80% of the design strength, the concrete strength of the pile foundation must be tested by a qualified unit with corresponding testing technology and rich testing experience.

[0003] The prior art document CN221461294U provides a testing device for large-diameter cast-in-place pile construction. The frame and connecting frame form a circular mounting cavity with the cooperation of the connecting components, allowing the device to be installed at any position on the pile foundation. The sliding block is located on one side of the frame, and the drilling rig is installed on the sliding block. The connecting components are located on the side of the frame near the connecting frame, and the driving components are located on the side of the frame near the sliding block. During testing, after the device is fixed, the sliding block is moved by the action of the driving components, which drives the drilling rig to move and drill. Then, the control system compares the test results with the standard curve of concrete strength according to the drilling time and drilling depth to obtain the tested concrete strength value. This improves the efficiency and accuracy of pile foundation strength testing during use.

[0004] Although the device has many beneficial effects, it still has the following problems: once the staff fixes the frame on the outside of the pile foundation, it is difficult to adjust the detection position of the pile foundation. If the detection position needs to be adjusted, the staff needs to disassemble and reassemble the frame, which can easily reduce the flexibility of the device when it is used. In view of this, we propose a building pile foundation strength testing device. Utility Model Content

[0005] This application provides a building pile foundation strength testing device, which solves the technical problem in the prior art where, after the operator fixes the frame to the outside of the pile foundation, it is difficult to adjust the testing position of the pile foundation. If the testing position needs to be adjusted, the operator needs to disassemble and reassemble the frame, which easily reduces the flexibility of the device during use. The device achieves the technical effect of allowing the operator to adjust the position of the connecting plate after fixing the first and second plates to the pile foundation, thereby facilitating flexible testing of different positions of the pile foundation without the need for the operator to disassemble and reassemble the first and second plates, thus improving the flexibility of the device during use.

[0006] This application provides a building pile foundation strength testing device, including: a first plate and a second plate;

[0007] Both the first and second sleeve plates have multiple through holes on both sides of their front surfaces. Bolts are installed in the holes, and nuts are threaded onto the outside of the bolts. The bottom of the first sleeve plate is equipped with a testing mechanism for testing the strength of the pile foundation.

[0008] The detection mechanism includes a connecting plate located at the bottom of the first sleeve plate. A through groove is formed at the bottom of the connecting plate, and a vertical plate is connected to the through groove via a screw drive. A first motor is installed on one side of the vertical plate, and a drill rod is fixedly connected to one end of the output shaft of the first motor. Sliding grooves are formed at the bottom of both the first sleeve plate and the second sleeve plate, and a slider is fixedly connected to the top of the connecting plate. The slider is slidably connected to the sliding groove.

[0009] By adopting the above technical solution and setting up a testing mechanism, after the staff fixes the first set of plates and the second set of plates on the pile foundation, the staff can adjust the position of the connecting plate, which facilitates flexible testing of different positions of the pile foundation without the need for the staff to disassemble and reassemble the first set of plates and the second set of plates, thereby improving the flexibility of the device when in use.

[0010] Optionally, both the slider and the groove have a T-shaped cross-section.

[0011] By adopting the above technical solution, and by setting both the slider and the groove cross-section to be T-shaped, this special shape design increases the stability of the slider in the groove, prevents the risk of the slider accidentally sliding out of the groove during circumferential rotation, and achieves the effect of enhancing the stability and safety of the device.

[0012] Optionally, the bottom of the outer wall of both the first and second sleeve plates is provided with multiple insertion holes, and a fixing plate is fixedly connected to one side of the top of the connecting plate. A sliding connecting rod for cooperating with the insertion hole is passed through one side of the fixing plate.

[0013] By adopting the above technical solution, when it is necessary to move the connecting plate, the staff pulls the pull plate to move the plug rod out of the plug hole, then pushes the connecting plate to the required position, and then releases the pull plate so that the plug rod is reset under the action of the spring and inserted into the new plug hole, thereby fixing the connecting plate and preventing the connecting plate from moving at will during testing.

[0014] Optionally, a pull plate is fixedly connected to one end of the insertion rod, and a spring is fixedly connected to the pull plate near the insertion rod, with one end of the spring fixedly connected to the fixing plate.

[0015] By adopting the above technical solution, when the connecting plate needs to be moved, the worker can pull the pull plate to overcome the spring force and move the plug rod out of the socket. After the connecting plate is moved to the required position, the pull plate is released, and the spring force pushes the plug rod to reset and insert it into the new socket, which simplifies the operation process of the plug rod and improves work efficiency.

[0016] Optionally, a pad is fixedly connected to the inner side of both the first and second sleeve plates, and the pad is made of rubber.

[0017] By adopting the above technical solution and setting the rubber pad, this design provides additional cushioning and friction, which helps to reduce damage to the pile foundation surface during the fixing process and increases the stability between the device and the pile foundation.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] 1. By setting up a testing mechanism, after the staff fixes the first set of plates and the second set of plates on the pile foundation, the staff can adjust the position of the connecting plate, which facilitates flexible testing of different positions of the pile foundation without the need for the staff to disassemble and reassemble the first set of plates and the second set of plates, thereby improving the flexibility of the device when in use.

[0020] 2. By setting up a fixed plate, insert rod, and insertion hole, when the connecting plate needs to be moved, the operator pulls the pull plate to move the insert rod out of the insertion hole, then pushes the connecting plate to the required position, and then releases the pull plate so that the insert rod is reset under the action of the spring and inserted into the new insertion hole, thereby fixing the connecting plate and preventing the connecting plate from moving randomly during testing.

[0021] 3. By setting a spring, when the connecting plate needs to be moved, the operator pulls the pull plate to overcome the spring force, causing the insertion rod to move out of the insertion hole; when the connecting plate is moved to the desired position, the pull plate is released, and the spring force pushes the insertion rod back to its original position and insert it into the new insertion hole, which simplifies the insertion rod operation process and improves work efficiency.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 This application discloses a building pile foundation strength testing device. The building pile foundation strength testing device includes: a first plate 1 and a second plate 2;

[0028] Both the first plate 1 and the second plate 2 have multiple openings through both sides of the front. Bolts 4 are installed in the openings, and nuts 5 are threaded on the outside of the bolts 4. The bottom of the first plate 1 is equipped with a testing mechanism 3 for testing the strength of the pile foundation.

[0029] The testing mechanism 3 includes a connecting plate 31, which is located at the bottom of the first set plate 1. A through groove is opened through the bottom of the connecting plate 31, and a vertical plate 38 is connected to the through groove through a screw drive 32. A first motor 39 is installed on one side of the vertical plate 38, and a drill rod 310 is fixedly connected to one end of the output shaft of the first motor 39. Both the bottom of the first set plate 1 and the second set plate 2 are provided with sliding grooves. A slider 33 is fixedly connected to the top of the connecting plate 31, and the slider 33 is slidably connected in the sliding groove. This allows the operator to flexibly adjust the testing position after fixing the first set plate 1 and the second set plate 2, thereby improving the flexibility of the device during use.

[0030] Reference Figure 2 and Figure 3 Both the slider 33 and the groove have T-shaped cross sections, which helps to prevent the slider 33 from falling out of the groove at will.

[0031] Reference Figure 2 and Figure 3 The lead screw drive component 32 includes a second motor, a lead screw, and a screw sleeve. A mounting groove is provided through one side of the connecting plate 31. The second motor is installed on one side of the connecting plate 31, and the output shaft of the second motor is rotatably connected in the mounting groove. The lead screw is fixedly connected to one end of the output shaft of the second motor. The screw sleeve is threaded on the outside of the lead screw and is slidably connected in the through groove. The bottom of the screw sleeve is fixedly connected to the top of the vertical plate 38, thereby facilitating the workers to drive the vertical plate 38, the first motor 39, and the drill rod 310 to move in the direction of the pile foundation.

[0032] Reference Figure 2 and Figure 3 The mounting slot is equipped with ball bearings, and the output shaft of the second motor is rotatably connected to the mounting slot through the ball bearings, thereby reducing the friction between the output shaft of the second motor and the transmission screw when they rotate.

[0033] Reference Figure 2 and Figure 3The bottom of the outer wall of the first plate 1 and the second plate 2 are provided with multiple insertion holes. A fixing plate 34 is fixedly connected to one side of the top of the connecting plate 31. A sliding connecting rod 35 for cooperating with the insertion hole is passed through one side of the fixing plate 34, so as to facilitate the positioning of the connecting plate 31 and prevent the connecting plate 31 from moving at will.

[0034] Reference Figure 2 and Figure 3 A pull plate 36 is fixedly connected to one end of the insertion rod 35. The size of the pull plate 36 is larger than the size of both ends of the insertion rod 35, so that the staff can pull the insertion rod 35.

[0035] Reference Figure 2 and Figure 3 A spring 37 is fixedly connected to the side of the pull plate 36 near the insertion rod 35. One end of the spring 37 is fixedly connected to the fixing plate 34, and the spring 37 is sleeved on the outside of the insertion rod 35, so as to prevent the insertion rod 35 from falling out of the insertion hole at will.

[0036] Reference Figure 1 and Figure 2 Both the first set of plates 1 and the second set of plates 2 have pads 6 fixedly connected to their inner sides. The pads 6 are made of rubber, which helps to increase the friction between the first set of plates 1, the second set of plates 2 and the pile foundation.

[0037] The implementation principle of the building pile foundation strength testing device according to an embodiment of this application is as follows: When using the device, firstly, the staff securely fixes the first plate 1 and the second plate 2 to the outside of the pile foundation to be tested through bolts 4 and nuts 5 in multiple openings through both sides of their front sides. This step ensures a stable connection between the device and the pile foundation, laying a solid foundation for subsequent strength testing.

[0038] Meanwhile, the sliding connection design of the slider 33 fixedly connected to the top of the connecting plate 31 within the groove allows the connecting plate 31 to move along the direction of the groove, that is, to rotate circumferentially around the direction of the pile foundation inside the first set of plates 1 and the second set of plates 2. When the connecting plate 31 needs to be moved, the operator can pull the pull plate 36 to move the insertion rod 35 and pull the spring 37, so that the insertion rod 35 moves out of one of the insertion holes. Then the operator can push the connecting plate 31 to move the slider 33. The movement of the connecting plate 31 can drive the vertical plate 38, the first motor 39 and the drill rod 310 to move through the screw drive 32. When the drill rod 310 moves to the designated position, the operator can release the pull plate 36, so that the pulled spring 37 rebounds, so that the pull plate 36 and the insertion rod 35 reset and insert into another insertion hole, positioning the connecting plate 31, so that the drill rod 310 can be used to inspect the pile foundation at different positions.

[0039] Subsequently, the lead screw drive component 32 begins to function. As the second motor starts, its output shaft drives the lead screw to rotate. Since the threaded sleeve is fitted on the outside of the lead screw and the bottom of the sleeve is fixedly connected to the top of the vertical plate 38, the rotation of the lead screw is converted into linear motion of the sleeve and the vertical plate 38, realizing the movement of the vertical plate 38 towards the pile foundation. After the vertical plate 38 and the drill rod 310 are adjusted to the appropriate position, the first motor 39 is started. The drill rod 310, which is fixedly connected to one end of the output shaft of the first motor 39, begins to rotate to perform strength testing on the pile foundation. Finally, based on the drilling time and drilling depth used, the test results are compared with the standard curve of concrete strength to obtain the tested concrete strength value.

[0040] This application provides a building pile foundation strength testing device. By setting up a testing mechanism 3, after the staff fixes the first set plate 1 and the second set plate 2 on the pile foundation, the staff can adjust the position of the connecting plate 31, which facilitates flexible testing of different positions of the pile foundation without the need for the staff to disassemble and reassemble the first set plate 1 and the second set plate 2, thereby improving the flexibility of the device when in use.

[0041] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. Those skilled in the art can connect all electrical components in this case to their compatible power supplies via wires. Appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described above, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art, therefore, electrical control will not be described further.
