Description

Technical Field

[0001] The utility model relates to the field of construction engineering, and more specifically to a guide device for hoisting a steel bar cage of a rotary pile into a hole. Background Art

[0002] The steel cage is generally made in sections. When hoisting, the four-point suspension method is used. First, the steel cage is hoisted horizontally. After the steel cage is hoisted to 0.5m from the ground, check whether the steel cage is stable. Then the main hoist slowly lifts the hook. According to the distance between the tail of the steel cage and the ground, the auxiliary hoist is commanded to cooperate with the hook lifting at any time. After the steel cage enters the hole, the distance between the bottom of the cage and the bottom of the hole is not less than 150mm. Fixed verification is carried out to avoid contact between the steel cage and the bottom of the hole, causing excessive deflection and deformation. During the placement process, the steel cage must also avoid collision and contact with the hole wall, damage the pile hole, cause the soil layer of the hole wall to fall off and collapse, cause defects at the bottom of the pile, and affect the quality of the pile. Therefore, it is necessary to guide the steel cage when it enters the hole to avoid touching the hole wall as much as possible.

It includes a first base, a connector, a slide, a guide mechanism, and a second base. The first base is erected above the pile hole and the casing, and the bottom is connected to the ground; the first base is connected to four connectors, and a slide is connected to the upper surface of each connector, and each slide can be detachably connected to a guide mechanism, and the four guide mechanisms are evenly distributed along the circumference; the second base is detachably connected to the top of the first base, and similarly, four connectors are connected to the upper surface of the second base, and a slide is connected to the upper surface of each connector, and a guide mechanism is connected to one end of each slide, and the four guide mechanisms are evenly distributed along the circumference. The utility model can play a guiding role when the steel cage is put into the hole, avoid the steel cage from colliding with the hole wall during the process of entering the hole, and improve the quality of the pile.

[0004] In the above-mentioned disclosed structure, the sliding seat is connected to the first base for combined adjustment for guidance. The circular steel cage can only be connected at a fixed position on the side, and cannot be rotated around the circle to adjust the alignment. The guiding mechanism used cannot adjust the alignment, which is not conducive to corresponding to steel cages of different diameters. The adaptability is poor and needs to be improved.
