When the clamping tables move, they drive the contact plate, the first clamping rod and the second clamping rod to move synchronously. When the contact plate contacts the column, the contact plate moves toward the inside of the accommodating groove, so that the first connecting rod on the contact plate squeezes the extrusion rod. The extrusion rod rotates around the lever, forcing the other end of the extrusion rod to push the second clamping rod and move toward the column. While the first clamping rod clamps the column, the first connecting rod further clamps the column.

This process can make the equipment more firmly connected to the ground, so that the equipment is not easily moved, which is beneficial to improving the stability of the equipment and the safety of construction; The disassembly mechanism 6 includes a movable plate 601, which is attached to the upper surface of the upper base plate 2. Both ends of the movable plate 601 are fixedly connected with sliding columns 602. Both sides of the upper base plate 2 are fixedly connected with fixed blocks 603. The upper surface of the fixed block 603 is slidably connected with a control column 604. The lower surface of the control column 604 is fixedly connected with a second tooth plate 605. The lower surface of the sliding column 602 is fixedly connected with a fixed column 606. A clamping block 607 is provided on the lower surface of the sliding column 602.

After the equipment is used, the control column 604 on the fixed block 603 is pressed downward to make the second tooth plate 605 and the block 607 misaligned. At this time, the block 607 will no longer be bound, and then under the action of the assist spring, the movable plate 601 on the sliding column 602 returns to its initial state; this process can make the equipment after use convenient and quick to detach from the column pile, achieve the effect of convenient disassembly, and help improve work efficiency.

[0014] Working principle: Before use, push the U-shaped device from the U-shaped part to the column pile exposed on the ground, so that the U-shaped device fits the column pile; Then, the movable plate 601 is pulled up and then rotated, so that the other end of the movable plate 601 moves to the top of the sliding column 602, and then the movable plate 601 is inserted into the sliding column 602, and the movable plate 601 is pulled so that the movable plate 601 and the column pile are engaged with each other. In the process of pulling the movable plate 601, the block 607 and the second tooth plate 605 contact each other, and the teeth on the second tooth plate 605 force the block 607 to deflect, and then reset under the action of the positioning spring, and finally the block 607 will move along the first tooth plate 605. The second tooth plate 605 moves with the sliding column 602 to realize the unidirectional movement of the movable plate 601. After the equipment is used, the control column 604 on the fixed block 603 is pressed downward to dislocate the second tooth plate 605 and the clamping block 607. At this time, the clamping block 607 will no longer be bound, and then the movable plate 601 on the sliding column 602 will return to the initial state under the action of the assisting spring. This process allows the equipment to be easily and quickly separated from the column pile after use, achieving the effect of convenient disassembly, which is conducive to improving work efficiency. After the equipment is engaged with the column pile, the external motor is started to rotate the semi-threaded rod 502. The rotation of the semi-threaded rod 502 will drive the connecting plates 504 at both ends of the threaded sleeve rod 302 to move along the direction of the semi-threaded rod 502, so that the sliding extrusion plate 505 under the connecting plate 504 connected to the connecting fixing rod 503 squeezes the extrusion block 507, and finally makes the drill bit 506 under the extrusion block 507 move downward and insert into the bottom surface. While the drill bit 506 moves downward, the push plate 513 under the extrusion column 508 squeezes the push plate 511, so that the push plate 511 pushes the push block 510 under the telescopic push rod 509 to extend, and finally makes the push block 510 insert into the ground. This process can make the equipment more firmly connected to the ground, so that the equipment is not easily moved, which is beneficial to improving the stability of the equipment and the safety of construction. The column to be connected to the column pile is hoisted by an external crane so that the column is above the column pile, and the external motor is started to rotate the semi-threaded rod 502. The rotation of the semi-threaded rod 502 drives the threaded sleeve rod 302 on the semi-threaded rod 502 to move along the direction of the semi-threaded rod 502, and at the same time, the clamping platform 303 connected to the threaded sleeve rod 302 moves synchronously. When the clamping platform 303 moves, it drives the contact plate 311, the first clamping rod 309 and the second clamping rod 310 to move synchronously. When the contact plate 311 contacts the column, the contact plate 311 moves toward the inside of the accommodating groove, so that the first connecting rod 307 on the contact plate 311 squeezes the squeezing rod 306. When the semi-threaded rod 502 rotates, it drives the transmission chain, so that the worm 316 at both ends of the transmission chain moves synchronously, and finally the first tooth plate 313 meshing with the turbine 317 moves upward. When the first tooth plate 313 moves upward, it pushes the upper base plate 2 on the connecting rod 312 to move upward. This process allows the equipment to be easily and quickly separated from the column pile after use, thereby achieving the effect of convenient disassembly and improving work efficiency.
