Technical Field

[0001] The present application relates to the technical field of auxiliary equipment for pile foundation construction, and in particular to auxiliary equipment for pile foundation construction. Background Art

[0002] Pile foundation construction refers to the construction process of the foundation of a building. The pile foundation consists of piles and pile caps. The construction methods of pile foundations are divided into two categories: precast piles and cast-in-place piles. During the pile foundation construction process, pouring pile foundation concrete is the top priority of construction and the key to the success of pile foundation construction. When lowering the steel cage into the pile hole, multiple sections of the steel cage need to be welded together.

[0003] During construction, usually a section of steel cage is lowered first, fixed, and then the other end of the steel cage is connected to the top of the lowered steel cage. The two adjacent steel cages are prone to offset, resulting in unstable fixation. For this reason, we propose an auxiliary equipment for pile foundation construction to solve the above problem.

[0025] A kind of auxiliary equipment for pile foundation construction, including a first limiting cylinder 10 and two first arc clamps 4, the left side surface of the first limiting cylinder 10 and the right side surface of the first limiting cylinder 10 are both provided with a first threaded hole 16, the inner wall of each first threaded hole 16 is threadedly connected with a first threaded rod 3, one end of each first threaded rod 3 is fixedly installed with a first rotating wheel 11, the outer surface of each first arc clamp 4 is fixedly inlaid with a first bearing 17, the other end of each first threaded rod 3 is fixedly installed with the inner ring of the first bearing 17, and the outer surface of each first arc clamp 4 is fixedly installed with a first limiting rod 2; specifically, the staff can drive the first threaded rod 3 to rotate by rotating the first rotating wheel 11, and by fixing one end of the two first threaded rods 3 with the inner rings of the two first bearings 17 respectively, so that each first threaded rod 3 can drive the first arc clamp 4 to adjust its position when rotating, and the two first arc clamps 4 can fasten and clamp the top of the bottom steel cage;

[0026] In this embodiment, a first limiting hole 19 is provided on the left side surface of the first limiting cylinder 10 and the right side surface of the first limiting cylinder 10, and one end of each first limiting rod 2 passes through the first limiting hole 19 and extends to the outside of the first limiting cylinder 10; three connecting rods 9 arranged in an annular manner are fixedly installed on the upper surface of the first limiting cylinder 10, and the top ends of the three connecting rods 9 are jointly fixedly installed with the second limiting cylinder 6; the front side of the second limiting cylinder 6 and the back side of the second limiting cylinder 6 are provided with a second threaded hole 15, and the inner wall of each second threaded hole 15 is threadedly connected with a second threaded rod 12, and one end of each second threaded rod 12 is fixedly installed with a second rotating wheel 5; specifically, the first limiting rod 2 cooperates with the first limiting hole 19, so that the first arc clamp 4 can remain stable when moving, and the three connecting rods 9 connect the first limiting cylinder 10 and the second limiting cylinder 6. The staff can weld the steel cages at both ends together in the gap between the three connecting rods 9, and the staff can adjust the position of the second threaded rod 12 through the second rotating wheel 5;

[0027] In this embodiment, two second arc-shaped clamps 8 are provided inside the second limiting cylinder 6, and the outer surface of each second arc-shaped clamp 8 is fixedly inlaid with a second bearing 13, and the other end of each second threaded rod 12 is fixedly installed with the inner ring of the second bearing 13; the front side of the second limiting cylinder 6 and the back side of the second limiting cylinder 6 are provided with a second limiting hole 14, and the outer surface of each second arc-shaped clamp 8 is fixedly installed with a second limiting rod 7, and one end of each second limiting rod 7 passes through the second limiting hole 14 and extends to the outside of the second limiting cylinder 6; the bottom surface of the first limiting cylinder 10 is fixedly installed with a base 1, and the bottom surface of the base 1 is provided with a through hole 18; specifically, when each second threaded rod 12 rotates, it can drive the second arc-shaped clamp 8 to move, and the second limiting rod 7 cooperates with the second limiting hole 14, so that the second arc-shaped clamp 8 can remain stable when moving, and the base 1 supports the first limiting cylinder 10.
