Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for ensuring the verticality of bored piles. Background Technology

[0002] With the increasing global emphasis on clean energy, the photovoltaic industry has experienced rapid development. Large-scale photovoltaic power plant construction requires a stable and reliable foundation to support the photovoltaic linkages, ensuring the photovoltaic modules maintain good performance and stability during long-term use. Micro-hole cast-in-place piles, due to their strong adaptability and good load-bearing capacity, have been widely used in photovoltaic linkage foundation engineering. The verticality of micro-hole cast-in-place piles directly affects their load-bearing capacity, seismic performance, and synergy with the superstructure. Excessive verticality deviation may lead to uneven stress on the pile body, tilting and fracture, or overall structural instability.

[0003] Referring to the existing technology CN213952222U - Drilled Cast-in-Place Pile Hole Verticality Control Device, it includes a stable base, support rod A, support rod B, collar A, collar B, and telescopic rod; a hinge base A1 is longitudinally symmetrically arranged at the top of the stable base, and a hinge base B1 is laterally symmetrically arranged at the top of the stable base; a hinge base A2 is symmetrically arranged on the outer side of the collar A, and a hinge base B2 is symmetrically arranged on the outer side of the collar B; there are two support rods A, whose bottom ends are hinged to hinge base A1, and whose top ends are hinged to hinge base A2 on the collar A; there are two support rods B, whose bottom ends are hinged to hinge base B1, and whose top ends are hinged to hinge base B2 on the collar B; this utility model can effectively control the verticality of the drilled cast-in-place pile during the construction process.

[0004] In the prior art, the stabilizing base is fixed to the ground. However, due to the unevenness of the ground, the stabilizing base cannot be fixed horizontally. Furthermore, since no buffer components are set, it cannot buffer external impacts (such as the impact force generated by punching), which affects the stability and verticality of the entire device and cannot improve stability. Utility Model Content

[0005] The present invention aims to provide a device for ensuring the verticality of bored piles, in order to solve the problem that the existing technology cannot buffer external impacts, which affects the stability and verticality of the entire device and fails to improve stability.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A device for ensuring the verticality of bored piles includes a base, with lifting components installed around the bottom of the base. Each lifting component includes a support leg, a motor fixed to the base, and a bidirectional lead screw driven by the motor. A lead screw seat is installed at the end of the bidirectional lead screw, and a connecting rod is hinged between the support leg and the corresponding lead screw seat. The device also includes a sleeve fixed to the base, with a positioning tube slidably connected to the sleeve along its axis. Furthermore, it includes multiple buffer components distributed along the circumference of the positioning tube. Each buffer component includes a sleeve with a movable buffer rod. A spring is provided between the buffer rod and the sleeve. One end of the sleeve is hinged to the base, and the end of the buffer rod away from the sleeve is hinged to the positioning tube.

[0008] The working principle and beneficial effects of this utility model:

[0009] First, adjust the height of one or more sides according to the undulations of the ground to ensure the base is placed horizontally on the ground. Specifically, a motor drives a double-acting lead screw to rotate, which in turn drives the lead screw seats on both sides to slide synchronously. The lead screw seats drive a connecting rod to rotate, and the connecting rod pushes the support legs downwards or upwards, thus adjusting the height of the support legs. This, combined with the support legs around the base, ensures the base is placed horizontally on the ground, correcting any tilting and adjusting the verticality of the positioning tube. The drill rod of the drilling rig drills downwards through the positioning tube. The impact force generated by ground vibration is transmitted through the base to the positioning tube, which slides up and down. This sliding motion causes the buffer rod to move within the sleeve, compressing the spring for cushioning. Combined with the rotation of the buffer rod and sleeve, this partially converts the horizontal or tilting force into axial pressure or tension on the sleeve and buffer rod, thus reducing vibration and minimizing the impact on the stability and verticality of the entire device, improving its overall stability.

[0010] Compared with the prior art, this application uses lifting components around the bottom of the base to adjust the height of one side of the base, so that it is placed horizontally on the ground, thereby correcting the tilt of the base and achieving the purpose of adjusting the verticality of the positioning tube; through the buffer component, the horizontal or tilting force is partially converted into axial pressure or tension on the sleeve and buffer rod, causing the spring to compress and play a shock absorption role, thereby reducing the impact on the stability and verticality of the entire device and improving the stability of the device.

[0011] In some embodiments, the positioning tube is fixedly sleeved with a branch tube, and the branch tube is fixedly sleeved with a fastening sleeve. The fastening sleeve facilitates alignment with the drill end of the drilling rig.

[0012] In some embodiments, the fastening sleeve is provided with external threads. The external threads facilitate connection with the body of the drilling rig.

[0013] In some embodiments, a mounting bracket is installed on top of the base, and the mounting bracket is equipped with a level. The level is used to quickly calibrate the level of the base.

[0014] In some embodiments, a limiting block is fixedly connected to the surface of the buffer rod, and a limiting groove adapted to the limiting block is formed on the inner sidewall of the sleeve. The limiting block is movably connected inside the limiting groove. This optimized solution allows the buffer rod to repeatedly compress the spring, thereby achieving better shock absorption.

[0015] In some embodiments, mounting blocks are fixedly provided around the base, and the lifting components are respectively installed within the mounting blocks. This optimization improves the stability of the bidirectional threaded rod during rotation. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: base 1, mounting block 2, connecting rod 3, support leg 4, sleeve 5, positioning tube 6, fastening sleeve 7, branch tube 8, buffer rod 9, sleeve 10, level 11, motor 12, double-acting lead screw 13, lead screw seat 14, and spring 15.

[0022] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0023] Example: A device for ensuring the verticality of bored piles, such as... Figure 1 and Figure 3As shown, the system includes a base 1, with lifting components installed at the four corners of the base 1. Each lifting component includes support legs 4 and mounting blocks 2 fixed to the base 1. The mounting blocks 2 have a hollow interior. A motor 12 is fixedly mounted on the mounting blocks 2, driving a bidirectional lead screw 13 extending into the mounting blocks 2. The ends of the bidirectional lead screw 13 are threadedly connected to lead screw seats 14. The lead screw seats 14 and the mounting blocks 2 are horizontally slidably connected. The bidirectional lead screw 13 is a transmission component with opposite thread directions at both ends, allowing it to drive two mating lead screw seats 14 to move synchronously in opposite directions when rotating. The horizontal slidable connection between the lead screw seats 14 and the mounting blocks 2 ensures smoother sliding of the lead screw seats 14. A connecting rod 3 is hinged between the support legs 4 and the corresponding lead screw seats 14.

[0024] like Figure 2 and Figure 4 As shown, the system also includes a vertically mounted sleeve 10 fixedly installed on the base 1. A positioning tube 6 is vertically slidably connected to the sleeve 10 along its axis. It also includes four buffer components distributed around the circumference of the positioning tube 6. Each buffer component includes a sleeve 5. The sleeve 10 has a movable buffer rod 9. A spring 15 is fixedly installed between the buffer rod 9 and the sleeve 5. The bottom of the sleeve 5 is hinged to the base 1, and the end of the buffer rod 9 away from the sleeve 5 is hinged to the positioning tube 6. The positioning tube 6 is pulled upwards by the four buffer components and the spring 15. A branch tube 8 is fixedly sleeved on the top of the positioning tube 6, and a fastening sleeve 7 with external threads is fixedly sleeved on the top of the branch tube 8. Levels 11 are fixedly installed around the top of the base 1. The level 11 is a commonly used positioning instrument in engineering; its structure and working principle will not be described in detail here.

[0025] First, adjust the height of one or more sides according to the undulation of the ground to make the base 1 horizontal on the ground. Specifically, when adjusting the height of one side of the support leg 4, the motor 12 on that side drives the double-acting lead screw 13 to rotate. The double-acting lead screw 13 drives the lead screw seats 14 on both sides to slide synchronously. The lead screw seats 14 drive the connecting rod 3 to rotate. The connecting rod 3 pushes the support leg 4 to move down or up, thereby achieving the purpose of adjusting the height of the support leg 4. In addition, the self-locking effect of the double-acting lead screw 13 is used to lock the position of the lead screw seat 14 when the double-acting lead screw 13 does not rotate. The level 11 on that side is used for auxiliary adjustment. With the support legs 4 around the base 1, the base 1 is placed horizontally on the ground, thereby correcting the tilt of the base 1 and achieving the purpose of adjusting the verticality of the positioning tube 6.

[0026] After the drill rod of the drilling rig passes through the positioning tube 6 and is positioned, it drills vertically downwards towards the ground. The impact force generated by the ground vibration is transmitted to the positioning tube 6 through the base 1. The positioning tube 6 slides up and down. Through the up and down sliding of the positioning tube 6, the buffer rod 9 moves inside the sleeve 5 to compress the spring 15 for buffering. In addition, in conjunction with the rotation of the buffer rod 9 and the sleeve 5, the force in the horizontal or inclined direction is partially converted into axial pressure or tension on the sleeve 5 and the buffer rod 9, which plays a role in shock absorption. This reduces the impact on the stability and verticality of the entire device and improves the stability of the device.

[0027] Compared with the prior art, this application uses lifting components around the bottom of the base 1 to adjust the height of one side of the base 1, so that it is placed horizontally on the ground, thereby correcting the tilt of the base 1 and achieving the purpose of adjusting the verticality of the positioning tube 6; through the buffer component, the force in the horizontal or tilt direction is partially converted into axial pressure or tension on the sleeve 5 and the buffer rod 9, causing the spring 15 to be compressed, which plays a role in shock absorption, thereby reducing the impact on the stability and verticality of the entire device and improving the stability of the device.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
