Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a static pressure pile structure with high stability. Background Art

[0002] Static pile driving is a method of pile foundation construction. It involves driving prefabricated piles into the soil using a static pile driver's weight and a counterweight on the driver's frame to provide a counterforce. Advantages of static pile driving: It completely avoids the vibration, noise, and pollution caused by hammering. Therefore, construction is noiseless, vibration-free, impact-free, and pollution-free.

[0003] In the related art, when the pile is pressed in, the pile cannot be kept completely vertical due to the force applied, and the pile is prone to tilting. Adjusting the verticality of the pile is troublesome and the adjustment accuracy is low. Utility Model Content

The screw transmission can further improve the stability during limiting and reduce the possibility of pile shaking.

[0008] Preferably, the synchronization component includes two first transmission shafts rotatably connected to the base, a second transmission shaft for transmitting and connecting the two first transmission shafts, and a drive motor for driving the second transmission shaft to rotate. A worm is fixedly connected to the first transmission shaft, and one end of the screw is fixedly connected to a worm wheel. The worm wheel and the worm are engaged with each other for transmission, and the first transmission shaft and the second transmission shaft are transmitted through a bevel gear.

[0009] Through the above technical solution, the second transmission shaft is driven to rotate by the driving motor, and then transmitted to the first transmission shaft through the engagement of the bevel gear. After the first transmission shaft rotates, the worm gear is driven to rotate through the worm, thereby further increasing the torque and improving the stability of the screw rod, so that the sliding blocks on both sides move synchronously in the same direction, which is convenient for vertical adjustment.

[0010] Preferably, the pile hole is connected to the outside on a side away from the second transmission shaft.

[0011] Preferably, a support rod is connected below the base, and a universal wheel is provided on the side of the support rod away from the base.

The second transmission shaft is driven to rotate by the driving motor, and then transmitted to the first transmission shaft through the meshing of the bevel gear. After the first transmission shaft rotates, the worm gear is driven to rotate by the worm, thereby further increasing the torque and improving the stability of the screw rod, so that the sliding blocks on both sides move synchronously in the same direction, which is convenient for verticality adjustment.

It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0017] Reference Figure 1A high-stability static pressure pile structure includes a base 1, a pile hole 2 is opened on the base 1, sliding grooves 3 are set on both sides of the pile hole 2, and the sliding grooves 3 are arranged oppositely. In order to improve the stability during pile pressing, a limiting component 4 is set on the sliding groove 3.

The abutment block 7 is used to abut and limit the pile body, thereby improving the stability of the pile body when it is pressed in and reducing the possibility of the pile body tilting.

[0019] Reference Figure 1 and 2 A screw rod 8 is rotatably connected in the sliding groove 3 , the screw rod 8 is threadedly connected and passes through the sliding block 5 , and the sliding block 5 slides in the sliding groove 3 through the rotation of the screw rod 8 .

[0020] Reference Figure 1 and 2 In order to facilitate the adjustment of the verticality of the pile body, a synchronization component is provided on the base 1 to drive the screw rods 8 in the two sliding grooves 3 to rotate synchronously.

[0021] Reference Figure 1 and 2 The synchronization component includes two first transmission shafts 9 rotatably connected to the base 1, a second transmission shaft 10 for connecting the two first transmission shafts 9, and a driving motor 11 for driving the second transmission shaft 10 to rotate.

[0023] Reference Figure 1 and 2 In order to make the sliding blocks 5 on both sides rotate synchronously in the same direction, the threads on the two screws 8 have the same rotation direction, and the threads on the two worms 12 have opposite rotation directions. When the second transmission shaft 10 rotates, the first transmission shafts 9 on both sides rotate in opposite directions. Therefore, setting worms 12 with opposite thread rotation directions can make the screws 8 on both sides rotate in the same direction at the same time.

[0024] Reference Figure 1 and 2 The pile hole 2 is connected to the outside at the side away from the second transmission shaft 10. The connection can facilitate the movement of the base 1, and the base 1 can be removed after the pile body is pressed in.

The transmission through the screw rod 8 can further improve the stability during limiting and reduce the possibility of pile body shaking. The second transmission shaft 10 is driven to rotate by the driving motor 11, and then transmitted to the first transmission shaft 9 through the engagement of the bevel gear 14. After the first transmission shaft 9 rotates, the worm gear 13 is driven to rotate through the worm 12, thereby further increasing the torque, and can improve the stability of the screw rod 8, so that the sliding blocks 5 on both sides move synchronously in the same direction, which is convenient for verticality adjustment.
