TECHNICAL FIELD
[0001] The application relates to the technical field of pile foundation detection, in particular to a pile foundation bearing capacity detection device. BACKGROUND
[0002] Pile foundation bearing capacity detection is an important test in construction engineering, aiming to evaluate the stability and safety of pile foundation under load. Traditional pile foundation bearing capacity detection methods rely on static load test and dynamic load test. Although these methods can provide relatively accurate data, they have many inconveniences in actual operation, such as complex equipment, tedious operation, high cost, etc. In recent years, static-dynamic method testing using explosive shock waves has been gradually introduced into pile foundation bearing capacity detection. This method can quickly obtain dynamic response data of pile foundation, improving detection efficiency and accuracy.
[0003] At present, in the pile foundation bearing capacity detection device of static-dynamic method testing, the counterweight mechanism is usually arranged above the explosive barrel. The shock wave generated by the explosion of the explosive makes the counterweight mechanism rise, so that the bottom of the explosive barrel is subjected to the recoil force, and the recoil force acts on the pressure sensor on the pile foundation. By comparing the values of the pressure sensor before and after the explosion, the bearing capacity of the pile foundation is detected, so as to determine whether the bearing capacity of the pile foundation meets the requirements. In order to improve safety, the counterweight mechanism needs to move vertically, so a support and a guide mechanism are usually arranged on the outer periphery of the counterweight mechanism. The support is fixed to the ground, and the guide mechanism is arranged on the support. When the counterweight mechanism moves upward under the impact of the explosive, it can move along the guide mechanism to ensure the vertical movement of the counterweight mechanism and reduce the risk of horizontal deviation.
[0004] However, in the case of different weights of the placed counterweight mechanism, since the contact area of the support with the ground is fixed, when the counterweight mechanism deviates horizontally and contacts the guide mechanism, the stability of the support is prone to be insufficient, which not only affects the accuracy of the detection result, but also may cause safety hazards. Therefore, how to further improve the stability and adjustability of the guide support of the counterweight mechanism has become a key problem to be solved.

Unless otherwise stated, the orientation words such as "inner" and "outer" used in the present application refer to the contour of the corresponding parts.
[0039] As shown in Figure 1 , Figure 2 and Figure 3 , the present application discloses a pile bearing capacity detection device (hereinafter referred to as "device"). The device comprises a detection mechanism, a power mechanism 2, a counterweight mechanism and a supporting mechanism 4, which can effectively improve the stability and safety of the counterweight mechanism during movement.
[0040] The detection mechanism is arranged on the upper end surface of the pile foundation 200, the power mechanism 2 is arranged above the detection mechanism, and the counterweight mechanism is arranged above the power mechanism 2. The power mechanism 2 can move the counterweight mechanism upward. The support mechanism 4 includes a fixed frame and an extension frame. The bottom of the fixed frame is arranged on the ground 100, and the fixed frame is arranged around the outer periphery of the counterweight mechanism. The fixed frame moves the counterweight mechanism vertically. The design of the fixed frame enables the counterweight mechanism to move smoothly in the vertical direction, avoiding the safety hazards caused by horizontal deviation. The extension frame is slidingly connected to the fixed frame. The extension frame can be horizontally extended relative to the fixed frame, so that the extension frame can be arranged on the ground 100. The extension frame is used to selectively increase the contact area of the support mechanism 4 and the ground 100, thereby improving the guiding and supporting stability and adjustability of the counterweight mechanism. The extension frame can be horizontally extended to facilitate adjustment of the contact area of the support mechanism 4 and the ground 100, further enhancing the stability of the entire device. In addition, the telescopic extension frame can facilitate flexible adjustment of the support area according to the weight of the counterweight mechanism, so that good support effect can be maintained under different weight conditions.

The display assembly can be a computer and a display screen for receiving and displaying data from the pressure sensor. Existing mechanisms can be selected.
[0042] Optionally, the power mechanism 2 comprises a power bucket 21 and a bucket cover 22, the power bucket 21 is used to carry the power source, and the power bucket 21 is arranged above the pressure sensor 11. The bucket cover 22 is arranged on the bucket opening at the upper end of the power bucket 21, and the bucket cover 22 is connected with the counterweight mechanism, so that the bucket cover 22 can move synchronously with the counterweight mechanism. The design of the power bucket 21 and the bucket cover 22 ensures the effective carrying and stable placement of the power source, and through the connection of the bucket cover 22 and the counterweight mechanism, the synchronous movement of the power mechanism 2 and the counterweight mechanism is realized, so that the power source in the power bucket 21 can drive the counterweight mechanism, thereby the high-pressure recoil force acts on the pressure sensor 11 to detect the bearing capacity. The power source can be gunpowder and the necessary ignition structure, and the power bucket 21 has sufficient strength; since the detection of the bearing capacity of the pile foundation 200 by the static and dynamic method has been the prior art, the specific structure and principle will not be described here, and the appropriate structure and method can be selected as needed.
[0043] As shown in Figure 1 , Figure 2 and Figure 3 , optionally, the counterweight mechanism comprises at least one counterweight block 31, and the counterweight block 31 can be driven by the impact of the power mechanism 2 to make the recoil impact force act on the detection mechanism, thereby detecting the bearing capacity. The counterweight block 31 can be made of cast iron or concrete material, which has high density and stability; when a plurality of counterweight blocks 31 are arranged, the plurality of counterweight blocks 31 are detachably connected and stacked.
[0044] Optionally, the fixing frame comprises a support 411 and a plurality of guide members 412, the bottom of the support 411 is arranged on the ground 100, and the support 411 is used to erect the guide members 412. The guide member 412 is provided with a guide through hole 4121, and a plurality of guide members 412 are arranged in layers, so that the axes of a plurality of guide through holes 4121 coincide and form a vertically extending guide channel, and the guide channel is used for vertical movement of the counterweight mechanism, so that the counterweight mechanism always maintains a vertical direction during upward and downward movement, thereby improving the stability and safety of the device and reducing the safety hazards caused by horizontal deviation of the counterweight mechanism. At the same time, since each guide member 412 is assembled and connected, the assembly and disassembly are facilitated, the portability and maintenance convenience of the device are improved, and the number of guide members 412 can be selectively increased or reduced according to the rising height of the counterweight mechanism. The support 411 can be made of steel, which has high strength and rigidity to ensure the stability of the entire device. The material of the guide member 412 can also be selected from steel or other high-strength materials to ensure the durability and stability of the guide member 412. For example, steel has high strength and rigidity, and alloy material has good corrosion resistance.
[0045] As shown in Figure 1 , Figure 2 and Figure 3As shown, the support mechanism 4 comprises a limiting piece 413 and a fastener 414. The upper end of the limiting piece 413 is hinged to the outer side wall of the guide piece 412, and the limiting piece 413 is attached to the outer side wall of the guide piece 412. The lower end of the limiting piece 413 can extend beyond the lower end surface of the guide piece 412, so that the lower end of the limiting piece 413 can be attached to the outer side wall of the adjacent guide piece 412. The limiting piece 413 attached to the outer side wall of the guide piece 412 can strictly align the adjacent guide pieces 412, improve the assembly accuracy, optimize the guiding effect of the guide channel, and reduce the risk of safety hazards caused by the horizontal offset of the counterweight mechanism. The outer side wall of the guide piece 412 is provided with a fastening hole 4122. One end of the fastener 414 is connected to the lower end of the limiting piece 413, and the other end of the fastener 414 is used to connect the fastening hole 4122 of the adjacent guide piece 412. The connection of the fastener 414 can enhance the connection strength between the guide pieces 412, improve the stability of the entire support mechanism 4, and improve the reliability and accuracy of the pile foundation 200 bearing capacity detection. The limiting piece 413 and the fastener 414 are arranged on opposite sides of the guide piece 412 to optimize the limiting and connecting effects.
[0046] The limiting piece 413 can be made of steel material, which has high strength and rigidity. The fastener 414 can be a bolt, and the fastening hole 4122 is a screw hole to ensure the firmness and reliability of the connection. The upper end of the limiting piece 413 is connected to the outer side wall of the guide piece 412 through a hinge structure, which can rotate freely within a certain range to facilitate the adjustment of the position and the disassembly of the guide piece 412. The hinge structure can adopt a shaft sleeve structure to ensure the flexibility and stability of the limiting piece 413 during rotation. The lower end of the limiting piece 413 extends beyond the lower end surface of the guide piece 412 and is attached to the outer side wall of the adjacent guide piece 412, which is fixed by the fastener 414 to prevent the guide piece 412 from loosening in the vertical direction. This design enables the multiple layers of guide pieces 412 to maintain a stable structure when impacted, enhancing the anti-vibration capability of the device.
[0047] As shown in FIG. 1, Figure 1 , Figure 2 and Figure 3As shown, the bottom of the guide 412 is optionally provided with a plurality of guide structures 415, and the upper end of the support 411 and the guide structure 415 is provided with a plurality of guide holes 416, and the guide structure 415 and the guide hole 416 are correspondingly matched. Among them, the guide structure 415 of the lowermost guide 412 is inserted into the guide hole 416 of the support 411; among the adjacent two guides 412, the guide structure 415 of the upper guide 412 is inserted into the guide hole 416 of the lower guide 412, so that the plurality of guides 412 can be stacked on the support 411 in turn. The arrangement of the guide structure 415 enables accurate alignment between different guides 412, improves the vertical movement accuracy of the counterweight mechanism, reduces the risk of horizontal deviation caused by misalignment of the guide 412, enhances the stability of the entire support mechanism 4, effectively reduces the risk of shaking or tilting of the counterweight mechanism during the rising process, and improves the safety and reliability of the device.
[0048] As shown in Figure 1 , Figure 2 and Figure 3 , optionally, the guide structure 415 includes a cylindrical portion 4151 and a conical portion 4152, the upper end of the cylindrical portion 4151 is connected to the bottom of the guide 412, the large end of the conical portion 4152 is connected to the lower end of the cylindrical portion 4151, and the axis of the cylindrical portion 4151 coincides with the axis of the conical portion 4152. This structure design makes the guide 412 more stable when stacked and less likely to misalign. The design of the cylindrical portion 4151 and the conical portion 4152 enables the guide structure 415 to be more stable and convenient to insert into the guide hole 416, improving the alignment accuracy between the guides 412, so that the counterweight mechanism can move smoothly in the vertical direction, effectively preventing safety hazards caused by horizontal deviation of the counterweight mechanism. At the same time, the combined design of the cylindrical portion 4151 and the conical portion 4152 also simplifies the installation process and improves the assembly efficiency.
[0049] The cylindrical portion 4151 and the conical portion 4152 of the guide structure 415 can be made of steel material, which has high strength and rigidity. The diameter of the guide hole 416 is slightly larger than the diameter of the cylindrical portion 4151, usually 0.1-0.5mm, which facilitates the smooth insertion of the guide structure 415. The large end design of the conical portion 4152 makes it easier to insert the guide structure 415 into the guide hole 416, avoiding the difficulty of insertion caused by improper alignment. This design not only improves the assembly efficiency of the guide 412, but also enhances the stability and reliability of the guide 412.

The end of the horizontal telescopic member 421 is provided with a locking member 422, which can engage with the end of the sliding groove to limit the maximum extension length of the horizontal telescopic member 421. The horizontal telescopic member 421 of the telescopic frame can freely extend and retract along the sliding groove of the fixed frame, thereby facilitating the selective increase of the contact area between the support mechanism 4 and the ground 100 as needed, improving the stability and safety of the entire support mechanism 4. The design of the locking member 422 effectively limits the maximum extension length of the horizontal telescopic member 421, preventing over-extension that could cause the horizontal telescopic member 421 to completely detach, thus improving the reliability of the device. The horizontal telescopic member 421 can be made of aluminum alloy, which is lightweight and high-strength, while the locking member 422 can be made of stainless steel, which is corrosion-resistant and robust.
[0051] In other embodiments, the horizontal telescopic member 421 can be L-shaped, including a horizontal rod and a vertical rod, with the horizontal rod slidably connected to the fixed frame and the vertical rod providing support.

The support member 411 is arranged vertically or at an angle. One end of the support leg 423 is hinged in the receiving groove 4211 of the horizontal telescopic member 421, allowing the support member 411 to flexibly adjust its angle. It can provide stable support in the vertical direction and also provide additional support in the inclined state, thereby further enhancing the stability of the entire device. Multiple sets of telescopic frames can be set as needed, symmetrically arranged on both sides of the fixed frame to improve stability. When the support leg 423 is inclined, the horizontal distance between the upper end of the support leg 423 and the pile foundation 200 is less than the horizontal distance between the lower end of the support leg 423 and the pile foundation 200, so as to further improve the support stability.
[0053] It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.
