Description

Technical Field

[0001] This utility model relates to the field of piling devices, and in particular to a piling device for foundation construction in building engineering. Background Technology

[0002] A spiral pile driver, also known as a spiral drilling rig or spiral pile press, is a mechanical device specifically designed for driving piles (usually spiral piles) into the soil during foundation construction. It works by rotating and applying downward pressure, allowing the pile to penetrate deep into the ground, providing a stable foundation for buildings.

[0003] Utility model announcement CN217174761U discloses a piling device for building foundation construction, including a base, a support frame on one side of the base, a fixing component on the side of the base away from the support frame, a motor at the center of the support frame, and a sliding plate near the surface of the fixing component. This utility model uses a fixing component on the side of the base away from the support frame, which includes a plug and a vertical plate. During drilling, the vertical plate inside the fixing component contacts the ground, and the plug is tightly connected to the ground. This ensures the overall structure is stable under the action of the fixing component, preventing shaking during piling. However, this type of piling device also has certain shortcomings. Because the bottom end of the drill rod is pointed, and there is no protection for the drill rod in this structure, there is a certain degree of danger.

[0004] Therefore, it is necessary to provide a new piling device for foundation construction in building engineering to solve the above-mentioned technical problems. Utility Model Content

[0013] Compared with related technologies, the piling device for foundation construction of building engineering provided by this utility model has the following beneficial effects:

[0014] Rotating the rotating rod brings the two semicircular ring plates closer together, and the two semicircular ring plates align. At this time, the moving plate drives the drill rod to descend, so that the conical structure at the bottom of the drill rod passes between multiple rollers. When the drill rod descends, the rollers are pressed, causing the second spring to be compressed. Since the conical structure of the drill rod is located between the two semicircular ring plates, it plays a protective role. In addition, the multiple rollers also provide a certain degree of support for the drill rod, which reduces the wear of the threaded rod to a certain extent. Attached Figure Description

A drill rod 2 is mounted on the lifting device via a drive device. The drive device is a second motor 8, which is fixedly installed on a moving plate 6.

[0023] The lifting device includes a bracket 5, a movable plate 6, two first motors 7, and two threaded rods 23. The bracket 5 is fixedly installed on the base 1. The two threaded rods 23 are rotatably connected to both sides of the bracket 5. The two first motors 7 are installed on the top of the bracket 5. The two first motors 7 can drive the two threaded rods 23 to rotate respectively. The movable plate 6 is threadedly connected to the two threaded rods 23 and connected to the drive device. The first motors 7 drive the two threaded rods 23 to rotate, and the second motor 8 drives the drill rod 2 to rotate, so as to realize the piling and drilling work.

[0024] The moving device includes a rotating rod 9, a guide rod 10, two first side plates 11, and two second side plates 12. The rotating rod 9 is rotatably connected to the base 1, and its two ends are respectively provided with left-hand threads and right-hand threads. The two first side plates 11 are respectively fixedly connected to two semi-circular ring plates 3, and the two first side plates 11 are respectively threaded to the two ends of the rotating rod 9. The guide rod 10 is fixedly installed on the base 1, and the two second side plates 12 are respectively fixedly connected to the two semi-circular ring plates 3. The guide rod 10 is movably inserted into the through holes opened in the two second side plates 12. The rotating rod 9 is rotated so that the two semicircular ring plates 3 approach each other and are joined together. At this time, the moving plate 6 drives the drill rod 2 to descend, so that the bottom conical structure of the drill rod 2 passes between multiple rollers 4. When the drill rod 2 descends, the rollers 4 are pressed, so that the second spring 21 is compressed. Since the conical structure of the drill rod 2 is located between the two semicircular ring plates 3, it plays a protective role. In addition, the multiple rollers 4 also play a certain supporting role for the drill rod 2, which reduces the wear of the threaded rod 23 to a certain extent.

[0025] The pressing device includes a top plate 13, a mounting plate 15, multiple first inclined blocks 16, and multiple moving components. The top plate 13 is fixedly mounted on a semi-circular ring plate 3. A movable rod 14 is threadedly connected to the top plate 13. The bottom end of the movable rod 14 is rotatably connected to the mounting plate 15. The mounting plate 15 has a semi-circular ring structure, and the inner side of the mounting plate 15 is in contact with the outer surface of the semi-circular ring plate 3. Multiple first inclined blocks 16 are fixedly mounted on the bottom of the mounting plate 15. Multiple moving components are mounted on the side walls of the semi-circular ring plate 3. Block 16 can drive multiple semicircular ring plates 3 to move. The moving assembly includes a second inclined block 17, a vertical plate 18, a first spring 19, and an elastic element. The second inclined block 17 movably passes through the side wall of the semicircular ring plate 3, and the inclined surface of the second inclined block 17 is in contact with the inclined surface of the first inclined block 16. The vertical plate 18 is fixedly installed at one end of the second inclined block 17 located on the inner side of the semicircular ring plate 3.

The elastic element includes a fixed frame 20, a second spring 21, and a movable frame 22. The fixed frame 20 is fixedly connected to the second inclined block 17. The movable frame 22 is located inside the fixed frame 20, and its two ends are slidably disposed in the grooves opened on the two opposite side walls of the fixed frame 20. The movable frame 22 is rotatably connected to the roller 4. The two ends of the second spring 21 are fixedly connected to the fixed frame 20 and the movable frame 22, respectively. The position of the roller 4 can be adjusted according to the use needs. Rotating the movable rod 14 causes the mounting plate 15 to move downward. The mounting plate 15 causes multiple first inclined blocks 16 to move downward to squeeze the second inclined block 17. After being squeezed, the second inclined block 17 moves to the center of the semicircular ring plate 3, thereby changing the position of the roller 4. When rotating the movable rod 14, the movable rod 14 causes the mounting plate 15 to move upward. Under the action of the compressed first spring 19, the second inclined block 17 can move away from the center of the semicircular ring plate 3. At this time, the roller 4 moves away from the center of the semicircular ring plate 3.
