AI Technical Summary
When the existing pile feeders apply force at the end of the prefabricated pile, it is difficult to ensure that the pile feeder is directly above the prefabricated pile, resulting in uneven force being applied during the downward movement of the prefabricated pile in the soil layer, which may lead to the deflection or burst of the pile body.
An anti-eccentric static pressure pile feeder is designed. By setting up an anti-eccentric component in the pile feeder assembly, including axle rod, gear, tooth plate, limit block, spring, fixing block, fixing rod and pull ring, the interaction of these components is used to ensure that the pile feeder is located directly above the end of the prefabricated pile, and the position of the main steel pipe is adjusted so as to align it with the center of the prefabricated pile.
By setting up anti-eccentric components, it is possible to ensure that the prefabricated piles are subjected to uniform force during the downward movement of the soil layer, avoiding the pile body skew or bursting, and improving the construction quality. At the same time, the design can adjust the overall length according to the distance to be moved down, and is suitable for deeper positions, improving the practicality of the pile feeder.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile drivers, in particular to an anti-eccentric static pressure pile driver. Background Art
[0002] Precast piles are now widely used in pile foundations of buildings because of their factory-made, static pressure or hammer construction, which can meet the requirements of different geological conditions and different working conditions. A static pressure pile driver is a static pressure pile driving device used to drive precast piles deep into the soil.
[0003] However, the existing pile drivers usually apply force directly on the top of the precast pile to drive it in. But when the pile driver presses on the end of the precast pile, it is difficult to ensure that the pile driver presses directly on the top of the precast pile, which can easily cause the force application point of the precast pile to deviate, resulting in uneven force on the precast pile during its downward movement in the soil layer, thereby causing construction quality defects such as pile body deflection or even bursting.

[0008] Preferably, the pile driver assembly comprises a main steel pipe, a screw rod is inserted into the interior of the main steel pipe, a guide block is fixedly provided below the screw rod, a top block is fixedly installed above the screw rod, a nut pair is connected to the outer wall of the screw rod, and a steering rudder is fixedly provided on the outer wall of the nut pair.

[0013] Preferably, the main steel pipe is provided with a groove corresponding to the guide block, and the nut pair is rotatably connected to the main steel pipe.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The new static pressure pile driver can draw a diameter line at the end of the precast pile in advance by setting the anti-eccentricity component, and place the main steel pipe at the end of the precast pile so that the two pull rings are located directly above the diameter line. Pull out the pull ring, and the pull ring drives the fixed rod and the tooth plate to move. The tooth plate drives the gear to rotate, and the two pull rings move symmetrically. The distance between the two pull rings and the edge of the precast pile is measured, and the position of the main steel pipe is adjusted so that the distance between the two pull rings and the edge of the precast pile is consistent. After the position adjustment of the main steel pipe is completed, release the pull ring. Under the elastic force of the spring, the tooth plate will return to the initial position, so that the main steel pipe is directly above the precast pile, so that the precast pile is evenly stressed during the subsequent downward movement in the soil layer, avoiding accidents.
[0016] 2. The new static pressure pile driver can adjust the total length according to the required downward moving distance. The steering wheel can be turned to drive the nut pair to rotate, the nut pair drives the screw rod to move upward, and the screw rod drives the top block to move upward, thereby extending the total length and being able to deliver piles to deeper positions, thus improving practicality.
