Description

Technical Field

[0001] This invention relates to a building pile foundation construction device, specifically a building pile foundation construction device that facilitates rapid positioning. Background Technology

[0002] In the construction of building pile foundations, the accurate positioning of the piles plays a decisive role in the overall quality and safety of the building project. Traditional pile foundation construction equipment often requires a significant amount of time for manual measurement and adjustment during positioning, which is not only inefficient but also susceptible to human error, making it difficult to guarantee positioning accuracy. Furthermore, during static pressure or hammer driving operations, the piles are prone to displacement due to the lack of effective fixing measures, further affecting construction quality and progress. With the construction industry's increasing demands for construction efficiency and quality, there is an urgent need for a building pile foundation construction device that can achieve rapid and accurate positioning and effectively fix the piles during construction.

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a construction pile foundation device that facilitates rapid positioning by significantly improving positioning efficiency and accuracy and reducing the time and error of manual measurement and adjustment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides a construction device for building pile foundations that facilitates rapid positioning. It includes a base, a first driving device connected in the middle of the base, a rotating output end of the first driving device arranged in a vertical direction and fixedly connected to a turntable arranged above the base, the turntable being able to rotate in a horizontal plane under the drive of the first driving device, a hydraulic support leg fixedly installed at the lower end of the base, and a second driving device connected to the top of the turntable, the second driving device having an up-and-down movement output end.

[0008] A guide rail frame is fixed to the top of the up-and-down motion output end via a connecting structure. A front slider and a rear slider are arranged within a slot in the guide rail frame. The bottoms of the front and rear sliders are slidably connected to a guide rail mounted on the bottom wall of the slot via a second guide rail slider structure. The upper parts of the front and rear sliders are threadedly connected to the forward and reverse thread sections of a first positive and negative threaded screw, respectively. The front and rear ends of the first positive and negative threaded screw are rotatably connected to the guide rail frame, and one end is fixed to the motor shaft of a third drive motor mounted on the guide rail frame via a coupling. A front clamping jaw is fixed on the front slider, and a rear clamping jaw is fixed on the rear slider. The front and rear clamping jaws can be joined to form a ring. Multiple sliding cavities are evenly spaced on the inner walls of the left and right clamping jaws. A compression spring is fixedly connected to the bottom of each sliding cavity, and a guide post is fixedly connected to the end of each compression spring. The guide post is slidably connected to the inner wall of the sliding cavity, and the front end of the guide post extends to the outside of the sliding cavity and has a ball socket seat. A ball head is rotatably installed in the ball socket seat.

[0009] A through hole is opened on the right side of the base. A through groove is opened on the base on the left and right sides of the through hole. The line connecting the horizontal center axes of the two through grooves is consistent with the radial direction of the through hole and is on the same line as the center point of the turntable. A movable bracket is slidably connected to each through groove. A U-shaped guide rod is fixedly connected to the top of each movable bracket located above the base. The open ends of the two U-shaped guide rods are arranged opposite each other. The two flanges of the U-shaped guide rods are inclined inward. A ball socket is opened at the outer end of each flange, and a ball head is rotatably installed in the ball socket. The bottom ends of the two movable brackets located below the base are fixedly connected to the sliding push mechanism. The two movable brackets can slide towards each other or slide apart in opposite directions along their respective through grooves under the drive of the sliding push mechanism.

[0010] The beneficial effects of this invention are as follows:

[0011] 1. Fast and accurate positioning: The turntable is driven by the third drive motor to rotate quickly and the precast concrete pile is rotated to the pile foundation point (the center of the through hole) directly above it. The third drive motor controls the first positive and negative threaded rods to move the front clamping claw and the rear clamping claw towards each other to clamp the pile body, which greatly improves the positioning efficiency and accuracy and reduces the time and error of manual measurement and adjustment.

[0012] 2. Stable clamping and construction: The guide posts, pressure springs, and ball head structures on the inner sides of the front and rear clamping claws not only provide stable pressure when clamping precast concrete piles, ensuring that the pile body will not shift during positioning and construction, but also allow the ball head to rotate within the ball socket, so as not to hinder the sinking of the pile body during static pressure or hammer driving operations, ensuring smooth construction.

[0013] 3. By using the second drive motor to drive the reciprocating screw to rotate, the lifting column can be moved up and down, thereby flexibly adjusting the height of the clamp-type claw to adapt to the construction needs of pile foundations of different heights, enhancing the versatility and applicability of the device. The locking universal wheels at the bottom of the base facilitate the movement of the device on the construction site, while the hydraulic outriggers provide stable support during construction, ensuring the stability of the device during operation and further improving the construction quality.

In one embodiment of the invention, the sliding pushing mechanism includes a left connecting rod 34 and a right connecting rod 35 located below the base, and the bottom ends of the two movable brackets are respectively connected to the middle of the left connecting rod 34 and the right connecting rod 35. The rear ends of the left and right connecting rods are threadedly connected to the forward and reverse threaded segments of the second forward and reverse threaded rod 32, respectively. The front ends of the left and right connecting rods are slidably connected to the left and right ends of the slide rod 33, respectively. A first fixing block 30 is fixed at each of the left and right ends of the second forward and reverse threaded rod, and a second fixing block 31 is fixed at each of the left and right ends of the slide rod 33.

[0025] Working principle:

[0026] The second drive motor 15 is started, and its output shaft drives the reciprocating screw 16 to rotate via a coupling. Since the reciprocating screw 16 is threadedly connected to the bottom of the lifting column 6, according to the principle of thread transmission, the rotation of the reciprocating screw 16 is converted into the up-and-down sliding of the lifting column 6 within the column 5, thereby adjusting the height of the front clamp 11 and the rear clamp 12 to a suitable construction height to meet different construction needs. Then, the third drive motor 10 is started, and its output shaft drives the first forward and reverse threaded screw 19 to rotate via a coupling. The forward threaded section and the reverse threaded section of the first forward and reverse threaded screw 19 are threadedly connected to the front slider 20 and the rear slider 21, respectively. As the first positive and negative threaded screw 19 rotates, the front slider 20 and the rear slider move towards each other within the guide rail 9, thereby driving the front clamping jaw 11 and the rear clamping jaw 12, which are fixedly connected to it, to move closer together and firmly clamp the precast concrete pile. The pressure spring in the inner sliding cavity 22 of the jaw provides elastic pressure, so that the ball head 25 at the front end of the guide column 24 fits tightly against the surface of the pile. At the same time, the ball head 25 can rotate within the ball socket, ensuring a stable clamping and not restricting the subsequent movement of the pile. Then, the first drive motor 18 is started, and its output shaft drives the turntable 4 to rotate on the base 1 through the reducer. When the turntable 4 rotates, it drives the connected column 5 and the lifting column 1 to rotate. The column 6, connecting block 7, connecting arm 8, guide rail 9, and the clamped precast concrete pile rotate together until the precast concrete pile is rotated directly above the through hole 13 on the base 1, with the center of the through hole 13 as the pile foundation point, completing precise positioning; then, the knob 29 is turned to drive the second positive and negative threaded rod 32 to rotate, which drives the two moving supports 27 to move closer to each other through the left connecting rod 34, so that the ball head 25 at the front end of the U-shaped guide rod frame 28 abuts against the precast concrete pile. In construction environments such as silty soil, when static pressure or hammer driving pile operations are carried out, additional support force is required to enhance the stability of the pile. Then, the precast concrete pile that has been positioned and clamped is... During the static pressure or hammer driving operation, the front clamping claw 11 and the rear clamping claw continuously clamp and fix the pile body to prevent it from shifting. The ball head 25 and the guide post 24 are coordinated by the rotation of the ball socket to adapt to the movement of the pile body during the sinking process without affecting the normal progress of the pile driving operation. After the precast concrete pile is deeply embedded and stable in the ground, the first drive motor 10 is operated in reverse to release the front clamping claw 11 and the rear clamping claw, releasing the clamping of the pile body. Then, the locking universal wheel 2 at the lower end of the base 1 is used to move the device away so that the precast concrete pile can be completely driven into place, completing the entire pile foundation construction process.
