Description

Technical Field

[0001] The utility model relates to the technical field of building construction tooling, in particular to a construction positioning auxiliary device for rigid composite piles. Background Art

[0002] Reinforced composite piles are a type of composite foundation piles. The construction method is to first drive in a cement mixing pile, and before the cement solidifies, insert a prefabricated pipe pile at the center of the cement mixing pile. During the downward pressure of the prefabricated pipe pile, an extrusion force will be generated on the cement mixing pile, making the cement mixing pile and the soil more tightly combined. The friction between the pipe pile and the cement composite pile is greater, and ultimately the reinforced composite pile has a better supporting effect and is not easy to sink into the soil.

[0003] The construction of reinforced composite piles requires the cooperation of equipment for driving cement mixing piles and equipment for driving prefabricated pipe piles. Due to the large size of the equipment, construction needs to be carried out in turns. When the prefabricated pipe piles are driven in, the construction needs to be carried out before the cement is solidified. This not only places requirements on the construction speed, but also on the driving position of the prefabricated pipe piles. The existing construction method is for multiple workers to manually lift the prefabricated pipe piles in a lifting state and cooperate with the lifting equipment to position them. This is not only labor-intensive, but also involves great risks. To this end, we propose a construction positioning auxiliary device for reinforced composite piles to solve the above problems.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 , a construction positioning auxiliary device for a rigid composite pile, comprising a positioning frame, wherein the positioning frame is provided with a guide assembly;

[0023] The guide assembly includes a plurality of bearing seats fixedly connected to the positioning frame, the bearing seats are rotatably connected to a first shaft, and the bearing seats are rotatably connected to a plurality of second shafts, the first shaft and the second shaft are fixedly provided with a rope shaft, and a pull rope is wound around the rope shaft, and the end of the pull rope away from the rope shaft is fixedly connected to a jacket;

[0024] In this design, when in use, multiple rope shafts can be used to drive the pull ropes to pull the jacket synchronously in different directions, thereby moving the jacket to the center point of the positioning frame, ultimately achieving the purpose of rapid positioning;

[0025] A driving mechanism is provided at one end of the first shaft, and a first bevel gear is fixedly connected to an end of the first shaft away from the driving mechanism, and second bevel gears are fixedly connected to both ends of the second shaft, the first bevel gear and the second bevel gear are meshed with each other, and two adjacent second bevel gears are meshed with each other, and one of the second shafts is provided with a second bevel gear only at one end;

[0026] In this design, when carrying out the construction of the rigid composite pile, the user determines the piling point according to the design requirements, and then sets the construction positioning auxiliary device at the piling point. At the same time, the prefabricated pipe pile is first hoisted near the positioning auxiliary device, and the piling point is located at the center of the positioning frame. Then the user first carries out the cement pile driving operation. During the cement pile driving operation, the prefabricated pipe pile can be clamped and fixed by the jacket. After the cement pile driving operation is completed, the cement pile driving equipment moves away. At this time, the user hoists the prefabricated pipe pile and drives the prefabricated pipe pile driving equipment to the vicinity of the piling point.

[0027] When the lifting device is lifted, the lifting lever is tightened, and the lifting lever is tightened, so that the lifting lever is tightened, and the lifting lever is tightened, so that the lifting lever is tightened, and the lifting lever is tightened. When the lifting lever is lifted, the lifting lever is tightened, and the lifting lever is tightened, the lifting lever is tightened, and the lifting lever is tightened. When the lifting lever is lifted, the lifting lever is tightened, and the lifting lever is tightened, the lifting lever is tightened, and the lifting lever is tightened

[0028] Furthermore, the positioning frame includes an annular base frame, a plurality of ground anchors are provided on the annular base frame, the upper end of the annular base frame is fixedly connected to a support leg, and the support leg is fixedly connected to a cross frame, the cross frame can be annular or polygonal, and a large space is reserved in the middle of the cross frame so as not to hinder the construction of the piling equipment. The cross frame is also provided with a lifting lug for facilitating the user to move the entire auxiliary device, and the ground anchor is used to fix the annular base frame to ensure that the positioning frame will not be displaced as a whole under the drive of the prefabricated pipe pile when the prefabricated pipe pile is positioned. The bearing seat is fixedly connected to the cross frame, and a guide rail is also fixedly connected to the cross frame. The jacket is slidably connected to the guide rail, wherein the guide rail is used to further adjust the prefabricated pipe pile when the prefabricated pipe pile moves to a position close to the cross frame to ensure that the prefabricated pipe pile is in a vertical state at this time.

[0029] Furthermore, the jacket comprises a C-shaped shell, a slider is fixedly connected to the C-shaped shell, the slider is slidably connected to the guide rail, the pull rope is fixedly connected to the side wall of the C-shaped shell, and a pipe clamp is sleeved on the C-shaped shell;

Not only will there be no interference with the cross frame when rotating the shaft rod, but it is also more labor-saving when used. A ratchet is provided in conjunction with the ratchet teeth. On the one hand, it is convenient to prevent the first shaft rod from rotating when the user lifts the crank handle. On the other hand, it is also used to prevent the rope shaft from rotating under the tension of the pull rope, thereby ensuring the stability of the positioning device when adjusting the position of the prefabricated pipe piles.

The guide jacket that can be replaced by the extension frame slides into the guide rail. At the same time, the extension frame made of elastic material allows a larger error and will not be damaged by the swing of the prefabricated pipe piles, so it is safer and more practical.

[0034] Furthermore, the number of the second shafts is not less than three. Under this design, the total number of rope shafts is not less than four, and the multiple rope shafts are arranged in a circular manner to ensure that the multiple jackets are evenly stressed in multiple directions, ensuring that the jackets can be pulled toward the center line of the horizontal frame.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
