Description

Technical Field

[0001] This invention relates to the field of building technology, and more specifically to a multi-functional platform for pile foundation construction. Background Technology

[0002] Pile foundations are required during building construction. During pile foundation construction, a reinforcing cage is placed into the pile hole, and then concrete is poured into the hole to fix the pile foundation. First, a crane is used to place a pile foundation construction platform above and around the pile hole. Then, the reinforcing cage is placed into the pile hole through the pile foundation construction platform. However, the central axis of the hoisted pile foundation construction platform is easily misaligned with the central axis of the pile hole. Consequently, centering the reinforcing cage through the pile foundation construction platform can cause a deviation between the center of the reinforcing cage and the center of the pile hole, resulting in inaccurate positioning of the reinforcing cage and affecting the construction quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a multi-functional pile foundation construction platform that enables the construction platform and the pile hole to be concentric.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-functional platform for pile foundation construction, comprising:

[0005] The support frame has reinforcing plates fixed at intervals around its inner wall. The top of each reinforcing plate is provided with a hanging seat for connecting to a crane. The hanging seat is provided with a positioning unit for centering the reinforcing cage.

[0006] One or more stabilizers are circumferentially arranged on the outer wall of the support frame, and a stabilizer cylinder is fixed to the top of each stabilizer.

[0007] The lifting plate is located at the top of the support frame and slides on the stabilizing cylinder when the support frame is hoisted and moved down after the support frame coincides with the center of the pile hole.

[0008] The centering adjustment mechanism, located at the bottom of the lifting plate, is used to adjust the center of the support frame to coincide with the center of the pile hole after the plate is moved into the pile hole.

[0009] Furthermore, the lifting plate includes a support plate disposed at the center of the support frame for connecting the centering adjustment mechanism and a sliding plate detachably disposed on the support plate at equal intervals around the periphery and slidably sleeved on the outer wall of the stabilizing cylinder.

[0010] Furthermore, the centering adjustment mechanism includes a dual-axis motor disposed at the top of the support plate. One output shaft of the dual-axis motor is connected to a lead screw located below the support plate. A rectangular threaded block is threaded onto the lead screw, and a rod connecting unit that is slidably connected to the support plate is disposed on the outer wall of the threaded block.

[0011] Furthermore, the rod connection unit includes a notch formed on the outer wall of the threaded block, a swing rod is axially connected to the notch, and a push rod is provided at the end of the swing rod away from the lead screw for clamping the inner wall of the pile hole. One end of the push rod is connected to one end of the swing rod through a rotating shaft. A T-shaped slide rod is fixedly connected to the top of the push rod, and a slide rail is provided at the bottom of the support plate to slide in contact with the T-shaped slide rod.

[0012] Furthermore, the stabilizing cylinder is provided with an anti-displacement mechanism for fixing the support frame when it is placed on the ground. The anti-displacement mechanism includes a threaded rod rotatably installed on the top of the stabilizing cylinder, a gear connected to the top of the threaded rod, a through hole opened on the stabilizing seat, and an insert rod threadedly sleeved on the threaded rod, which slides through the inside of the stabilizing cylinder and passes through the through hole for insertion with the ground.

[0013] Furthermore, the inner wall of the stabilizing cylinder is fixed with symmetrically arranged limiting plates, the outer wall of the insert rod is provided with a limiting groove for the limiting plates to slide against each other, and the bottom end of the insert rod is a conical structure.

[0014] Furthermore, the stabilizing cylinder has symmetrical locking holes on both sides, and the top of the sliding plate is provided with a locking unit for connecting with the locking holes when the support frame is placed on the ground.

[0015] Furthermore, the locking unit includes a fixed frame disposed at the top of the slide plate and sleeved on the outside of the stabilizing cylinder, a receiving groove symmetrically opened on the inner wall of the fixed frame, a locking block that fits and slides inside the receiving groove and extends into the lock hole, and a spring for connecting the locking block with the inner wall of the receiving groove.

[0016] Furthermore, the other output shaft of the dual-axis motor is provided with an adjusting component for adjusting the rotation of the gear after the locking hole is connected to the locking block. The adjusting component includes a fixing ring installed on the other output shaft of the dual-axis motor. A gear ring that meshes with a plurality of the gears is concentrically sleeved on the outside of the fixing ring. A fixing rod is circumferentially arranged between the outer wall of the fixing ring and the inner wall of the gear ring.

[0017] Furthermore, the positioning unit includes an electric push rod mounted on the hanger, and the output shaft of the electric push rod is connected to a positioning plate for clamping and positioning the reinforcing cage.

[0018] Compared with existing technologies, the present invention has the following advantages: By setting up a support frame, lifting plate, stabilizing seat, stabilizing cylinder, and centering adjustment mechanism, the present invention facilitates the centering adjustment mechanism's clamping of the inner wall of the pile hole, ensuring the center of the centering adjustment mechanism coincides with the center of the pile hole. This allows the center of the support frame to coincide with the center of the pile hole before placing the reinforcing cage, providing the possibility for precise positioning of the reinforcing cage. The anti-displacement mechanism design facilitates the insertion and fixing of the insertion rod to the ground, improving the connection stability between the support frame and the ground, preventing support frame displacement during reinforcing cage placement, and thus facilitating subsequent reinforcing cage construction. The locking unit design fixes the height of the support plate, providing stability for the connection between the adjusting component and multiple gears. When the dual-axis motor controls the adjusting component, multiple insertion rods can be simultaneously inserted into the ground while the push rod disengages from the inner wall of the pile hole. Disconnecting the support plate from the sliding plate facilitates the removal of the centering adjustment mechanism from inside the pile hole, providing convenience for placing the reinforcing cage within the pile hole.

[0033] like Figure 1-9 As shown, the present invention provides a multi-functional platform for pile foundation construction, comprising:

[0034] The support frame 1 has reinforcing plates 2 fixed at intervals around its inner wall. The top of each reinforcing plate 2 is provided with a hanging seat 3 for connecting to the crane. The hanging seat 3 is provided with a positioning unit for centering the reinforcing cage.

[0035] One or more stabilizing seats 5 are circumferentially arranged on the outer wall of the support frame 1, and each stabilizing seat 5 is fixedly connected to a stabilizing cylinder 6 at its top.

[0036] The lifting plate is set at the top of the support frame 1 and will slide on the stabilizing cylinder 6 when the support frame 1 is hoisted and lowered after the support frame 1 coincides with the center of the pile hole.

[0037] The centering adjustment mechanism, located at the bottom of the lifting plate, is used to adjust the center of the support frame 1 to coincide with the center of the pile hole after the plate is moved into the pile hole.

[0038] In use, by connecting the hoisting rope of the crane to the lifting base 3, the support frame 1 can be suspended and placed above the pile hole where the reinforcing cage is to be placed. However, when the support frame 1 is placed on the ground, the central axis of the support frame 1 is easily misaligned with the central axis of the pile hole. Therefore, this design incorporates a centering adjustment mechanism. The suspension of the support frame 1 by the crane will also suspend the centering adjustment mechanism. When the centering adjustment mechanism moves into the pile hole and the support frame 1 has not yet touched the ground, the crane stops working, and then the centering adjustment mechanism is activated. The center of the support frame 1 is aligned with the center of the pile hole by clamping the inner wall of the pile hole, thereby aligning the central axis of the support frame 1 with the central axis of the pile hole. Then, the crane is started. Because the centering adjustment mechanism clamps the inner wall of the pile hole, the support frame 1 will be stably lowered to the ground. During the lowering process of the support frame 1, the stabilizing cylinder 6 will slide on the lifting plate, which makes it easy for the support frame 1 to be concentric with the pile hole when it is placed on the ground. Therefore, this design effectively achieves the alignment of the center of the support frame 1 with the center of the pile hole before placing the reinforcing cage, thereby providing convenience and improving the quality of the subsequent construction of the reinforcing cage.

[0039] It should be noted that the lifting plate includes a support plate 7 located at the center of the support frame 1 for connecting the centering adjustment mechanism, and a sliding plate 8 detachably mounted on the support plate 7 at equal intervals around the circumference and slidably fitted onto the outer wall of the stabilizing cylinder 6. This design, through the detachable connection between the sliding plate 8 and the support plate 7, facilitates the removal of the sliding plate 8 from the support plate 7 after the support frame 1 is aligned with the center of the pile hole and before the reinforcing cage is placed. This allows the sliding plate 8 to move the centering adjustment mechanism out of the pile hole, making it possible to place the reinforcing cage into the pile hole within the support frame 1. It should be noted that the support plate 7 and the sliding plate 8 are connected by bolts.

[0040] It should be noted that the centering adjustment mechanism includes a dual-axis motor 9 located at the top of the support plate 7. One output shaft of the dual-axis motor 9 is connected to a lead screw 10 located below the support plate 7. A rectangular threaded block 11 is threaded onto the lead screw 10. The outer wall of the threaded block 11 is circumferentially provided with a rod connecting unit that is slidably connected to the support plate 7. With this design, by starting the dual-axis motor 9 to rotate forward, the dual-axis motor 9 drives the lead screw 10 to rotate. The threaded connection between the lead screw 10 and the threaded block 11 causes the rod connecting unit to move, facilitating the rod connecting unit to clamp the inner wall of the pile hole, thereby realizing the centering adjustment of the centering adjustment mechanism and making it possible to center the support frame 1 and the pile hole.

[0041] It should be noted that the rod connection unit includes a notch 14 opened on the outer wall of the threaded block 11. A swing rod 12 is axially connected inside the notch 14. A push rod 13 for clamping the inner wall of the pile hole is provided at one end of the swing rod 12 away from the lead screw 10. One end of the push rod 13 is connected to one end of the swing rod 12 through a rotating shaft 32. A T-shaped slide rod 15 is fixedly connected to the top of the push rod 13. A slide rail 16 is opened at the bottom of the support plate 7 to slide in contact with the T-shaped slide rod 15. With this design, when the dual-axis motor 9 rotates forward, the lead screw 10 will rotate, causing the threaded block 11 to move downward and drive the swing rod 12 to swing. The swing rod 12 will push the push rod 13 to move laterally, causing the push rod 13 to drive the T-shaped slide rod 15 to slide inside the slide rail 16, so that the four push rods 13 can expand outward, making it easier for the four push rods 13 to clamp the inner wall of the pile hole, realize the center adjustment operation, and facilitate the center adjustment of the support frame 1, so that the central axis of the support frame 1 is coaxial with the central axis of the pile hole, which provides the possibility for precise positioning of the steel cage in the pile hole later.

[0042] It should be noted that the stabilizing cylinder 6 is equipped with an anti-displacement mechanism for fixing the support frame 1 when it is placed on the ground. The anti-displacement mechanism includes a threaded rod 19 rotatably mounted on the top of the stabilizing cylinder 6, with a gear 26 connected to the top of the threaded rod 19. The stabilizing seat 5 has a through hole 4, and an insert rod 21 is threadedly sleeved on the threaded rod 19, slidingly inserted into the inside of the stabilizing cylinder 6 and passing through the through hole 4 for insertion into the ground. With this design, when the gear 26 rotates, it will drive the threaded rod 19 to rotate. Through the threaded connection between the slide rail 16 and the insert rod 21, the insert rod 21 will slide downward on the inner wall of the stabilizing cylinder 6, facilitating the insertion of the insert rod 21 into the ground and achieving the positioning of the support frame 1. This effectively prevents the support frame 1 from shifting when placing the reinforcing cage, thereby providing stability for the subsequent construction of the reinforcing cage.

[0043] It should be noted that the inner wall of the stabilizing cylinder 6 is fixed with symmetrically arranged limiting plates 20, and the outer wall of the insertion rod 21 is provided with a limiting groove 22 for the limiting plates 20 to slide against each other. The bottom end of the insertion rod 21 has a conical structure. This design facilitates the stable raising and lowering of the insertion rod 21 through the sliding operation of the limiting plates 20 and the limiting groove 22, making it easier for the insertion rod 21 to be inserted into the ground to fix the support frame 1, effectively preventing the support frame 1 from shifting on the ground.

[0044] It should be noted that the stabilizing cylinder 6 has symmetrically arranged locking holes 18 on both sides, and the top of the sliding plate 8 is provided with a locking unit for connecting with the locking holes 18 when the support frame 1 is placed on the ground. This design, through the connection between the locking unit and the locking holes 18, makes it possible for the gear 26 to move and for the insertion rod 21 to be inserted into the ground.

[0045] It should be noted that the locking unit includes a fixing frame 17 disposed at the top of the slide plate 8 and sleeved on the outside of the stabilizing cylinder 6, a receiving groove 23 symmetrically formed on the inner wall of the fixing frame 17, a locking block 24 that slides against the inside of the receiving groove 23 and extends into the inside of the locking hole 18, and a spring 25 for connecting the locking block 24 with the inner wall of the receiving groove 23. With this design, since the end of the locking block 24 contacts the outer wall of the stabilizing cylinder 6, the spring 25 will be in a compressed state. When the slide plate 8 drives the fixing frame 17 to slide on the stabilizing cylinder 6, after the locking block 24 aligns with the locking hole 18, the elastic force of the spring 25 will cause the locking block 24 to insert into the locking hole 18, thus connecting the slide plate 8 and the stabilizing cylinder 6, thereby fixing the height of the support plate 7.

[0046] It should be noted that the other output shaft of the dual-axis motor 9 is provided with an adjusting component for adjusting the rotation of the gear 26 after the lock hole 18 is connected to the locking block 24. The adjusting component includes a fixing ring 27 installed on the other output shaft of the dual-axis motor 9. A gear ring 29 that meshes with and is connected to a plurality of gears 26 is concentrically sleeved on the outside of the fixing ring 27. A fixing rod 28 is circumferentially arranged between the outer wall of the fixing ring 27 and the inner wall of the gear ring 29. With this design, once the locking block 24 is fixed to the locking hole 18, the gear ring 29 and the gear 26 will mesh, improving the connection stability between the gear ring 29 and the gear 26. Then, the dual-axis motor 9 is started to reverse, and the dual-axis motor 9 drives the fixed ring 27 to rotate, which in turn drives the gear ring 29 to rotate through the fixed rod 28, making it easier to rotate multiple gears 26 and providing power for the insertion rod 21 to move down and insert into the ground. At the same time, the dual-axis motor 9 reverses, which will cause multiple push rods 13 to move closer to the lead screw 10 and break the clamping on the inner wall of the pile foundation, thereby facilitating the pulling of the support plate 7 to move the centering adjustment mechanism out of the pile hole.

[0047] It should be noted that the positioning unit includes an electric push rod 30 mounted on the hanging base 3, and the output shaft of the electric push rod 30 is connected to a positioning plate 31 for clamping and positioning the reinforcing cage. With this design, when the connection between the support plate 7 and the sliding plate 8 is disconnected, the worker can lift the support plate 7, which will cause the centering adjustment mechanism to move upward and disengage the gear ring 29 from the gear 26. Simultaneously, the centering adjustment mechanism will disengage from the pile hole, effectively making it possible to place the reinforcing cage within the pile hole.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
