Description

Technical Field

[0001] The invention relates to the field of engineering construction auxiliary equipment, in particular to an adjustable rotary pile steel pipe column positioning device. Background Art

[0002] At present, ground pile construction usually uses full-rotation drilling rigs for drilling. The full-rotation drilling rig is driven by a power device to rotate the drilling rig rotary device, thereby driving the drill rod with a drill bit to rotate. The drill rod is hollow and the drill bit cuts the soil. The power device drives the drill rod to rotate. The hydraulic device on the full-rotation drilling rig provides a downward vertical force to press the drill rod into the ground to form a guard arm. The soil in the drill rod is taken out through the peripheral equipment, and the steel pipe column below is poured with concrete. When the concrete is initially set, the full-rotation drilling rig and the drill rod are directly hoisted out by a crane for use in inserting the steel pipe column under the next pile.

[0003] The steel pipe column of rotary pile is a load-bearing column welded with steel pipes, usually divided into two parts: the column body and the column foot. The part below 2 meters at the bottom of the steel pipe column is called the column foot, and the part above 2 meters is called the column body. There are three main forms of rigid column footing of steel pipe columns: exposed column footing, external column footing and embedded column footing.

[0004] Before installing the steel pipe column, it is necessary to mark the base layer according to the design drawings, determine the installation position of the steel pipe pile, and use a level to determine the height of the steel pipe pile. The existing steel pipe column is difficult to adjust, resulting in position errors after installation. The existing steel pipe column needs to be dismantled and reinstalled. At the same time, the part of the steel pipe column exposed to the ground is higher than the full-rotation drilling rig. During the lifting process, the drill rod is likely to collide with the steel pipe column, thereby affecting the verticality of the steel pipe column. This needs to be improved.

The spacing of the lifting rod 603 is equal to the height difference between the head end and the tail end of the driving member 204. At the same time, when the driving member 204 rotates 360 degrees, the driving member 204 squeezes the slot 604 through the lifting rod 603 to make it move upward, and the moving distance is equal to the driving member 204 has a height difference between the head end and the tail end, and the card slot 604 drives the steel pipe column 601 to move upward to the height of the rotary drilling drill rod to prevent the rotary drilling column from colliding with the device when it descends to drill a hole.

Since the spur gear 103 is located in the first connecting groove 301 and meshes with the first connecting groove 301, the moving plate 302 is dynamically connected to the support platform 1. When the spur gear 103 rotates, it drives the moving plate 302 to move horizontally through the first connecting groove 301, and the moving plate 302 drives the support The frame 303 moves laterally. Since the two limit plates 402 are respectively located on both sides of the first connecting groove 301 and are in sliding contact with the first connecting groove 301, that is, when the moving plate 302 moves laterally, the moving plate 302 drives the directional moving block 401 to move laterally through the limit plates 402. Since the steel pipe column 601 and the I-shaped guide rail 602 pass through the column mounting groove 404 and are in sliding contact with the directional moving block 401, at the same time, the abutment block 403 is located in the I-shaped guide rail 602 and is in sliding contact with the steel pipe column 601, that is, the directional moving block 401 drives the steel pipe column 601 to move laterally to adjust the position. At the same time, when the column 104 is driven to rotate by toggling the push rod 105, the column 104 is rotated. The column 104 drives the meshing teeth 106 to rotate. Since the meshing teeth 106 are located in the second connecting groove 503 and meshed with the second connecting groove 503, the front and rear ends of the directional moving block 501 are in sliding contact with the directional moving block 401, that is, when the meshing teeth 106 rotate, the directional moving block 501 is driven to move longitudinally through the second connecting groove 503, and the directional moving block 501 drives the directional moving block 401 to move longitudinally along the slot 304.
