Description

Technical Field

[0001] The utility model relates to a building foundation pile installation device, in particular to a building foundation pile installation calibration device. Background Art

[0002] A pile foundation is a deep foundation consisting of piles and a pedestal or a single foundation connected by columns and pile foundations. If the pile body is completely buried in the soil and the bottom of the pedestal is in contact with the soil, it is called a low pedestal pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the pedestal is above the ground, it is called a high pedestal pile foundation. Building pile foundations are usually low pedestal pile foundations. Pile foundations are widely used in high-rise buildings. There are two existing construction methods for building foundation piles, namely precast piles and cast-in-place piles. Precast piles are made by driving precast reinforced concrete piles into the ground. The advantages are material saving and high strength, and they are suitable for buildings with higher requirements. Cast-in-place piles are made by drilling holes in the construction site, placing steel bars and pouring concrete. The construction difficulty is low and there is no limit on the number of machines, but the bearing capacity is low. In comparison, most people use precast piles.

[0003] During the installation of precast piles, improperly adjusted pile angles can cause the piles to shift underground, reducing their bearing capacity. Therefore, a calibration device for pile installation is crucial. However, in existing techniques, the clamping mechanism for pile installation is not synchronized, resulting in a loss of coaxiality between the pile and the installation location, impairing installation accuracy. Utility Model Content

[0004] The main purpose of the present disclosure is to provide a construction foundation pile installation calibration device to effectively solve the problems raised by the inventor in the above background technology.

[0007] Preferably, positioning rails are fixedly installed on both sides of the top of the calibration base, and a double-threaded screw is rotatably installed between the positioning rails on both sides. A moving seat is fixedly installed on the two vertical slide rails, and the moving seat is threadedly installed on the double-threaded screw. The moving directions of the two vertical slide rails are opposite, and one end of the double-threaded screw is fixedly connected to an adjustment handle.

[0008] Preferably, a parallel limiting rod is fixedly mounted on the positioning rail, and the movable seat is slidingly sleeved on the parallel limiting rod.

[0009] Preferably, a movable opening communicating with the slide groove is opened on the side surface of the vertical slide rail, and teeth are fixedly mounted on the side surface of the guide block, and the teeth pass through the movable opening and extend to the outside of the vertical slide rail.

[0011] Preferably, the length of the movable opening is smaller than the length of the chute.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , the utility model provides the following embodiments:

[0022] A building foundation pile installation and calibration device includes a calibration base 1, a mounting through hole 2 is opened in the middle of the calibration base 1, two vertical slide rails 3 are slidably installed on the top of the calibration base 1, and the two vertical slide rails 3 are symmetrically arranged about the mounting through hole 2, a slide groove is opened on the side where the two vertical slide rails 3 are close to each other, and a guide block 4 is slidably installed in the slide groove, one side of the guide block 4 is fixedly connected to an extension arm 5, the other end of the extension arm 5 is fixedly connected to a straightening plate 6, and the midpoint between the two straightening plates 6 is coaxially arranged with the center of the mounting through hole 2.

[0023] Specifically, positioning rails 7 are fixedly installed on both sides of the top of the calibration base 1, and a double-threaded screw 8 is rotatably installed between the positioning rails 7 on both sides. A moving seat 10 is fixedly installed on the two vertical slide rails 3, and the moving seat 10 is threadedly installed on the double-threaded screw 8. The moving directions of the two vertical slide rails 3 are opposite. One end of the double-threaded screw 8 is fixedly connected to an adjustment handle 11. A parallel limit rod 9 is fixedly installed on the positioning rail 7, and the moving seat 10 is slidably sleeved on the parallel limit rod 9.

[0024] Specifically, a movable opening 12 communicating with the slide groove is opened on the side of the vertical slide rail 3 , and teeth 13 are fixedly installed on the side of the guide block 4 , and the teeth 13 pass through the movable opening 12 and extend to the outside of the vertical slide rail 3 .

[0025] Specifically, a motor base 14 is fixedly installed on the side of the vertical slide rail 3, a servo motor 15 is fixedly installed on the motor base 14, and the output end of the servo motor 15 is fixedly connected to a gear 16, the gear 16 is engaged with the teeth 13, and the servo motor 15 works to rotate the gear 16 and drive the teeth 13 to move in the movable mouth 12, and then the guide block 4 is raised and lowered.

[0026] Specifically, the length of the movable opening 12 is smaller than the length of the chute, so that when the teeth 13 move in the movable opening 12, the guide block 4 is always located in the chute to avoid separation.

[0027] The specific implementation of this embodiment is as follows: when installing the foundation pile, the adjusting handle 11 is rotated, which will drive the double-threaded screw 8 to rotate, and then the movable seat 10 moves, so that the two vertical slide rails 3 move toward each other, and the two straightening plates 6 will close and clamp the foundation pile, so that the foundation pile remains in a vertical state and avoids deviation.

[0028] When the foundation pile is aligned with the installation through hole 2, the servo motor 15 drives the gear 16 to rotate. Under the meshing transmission action of the gear 16 and the rack 13, the rack 13 drives the guide block 4 to slide in the slide groove, so that the straightening plate 6 rises and falls, thereby the foundation pile can be lowered for installation.
