Description

Technical Field

[0001] This utility model relates to the field of percussion pile machine technology, specifically to an impact angle adjustment mechanism for the square hammer of a percussion pile machine. Background Technology

[0002] A drilling pile driver consists of a pile hammer, a pile frame, and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods (commonly known as a gantry) at the front of the pile frame and is lifted by a hoisting hook. The pile frame is a steel tower structure with a winch at the rear for lifting the pile and pile hammer. During operation, the impact angle of the hammer needs to be adjusted using an angle adjustment mechanism.

[0003] The existing impact angle adjustment mechanism of the square hammer of the drilling pile driver adjusts the impact angle of the hammer by rotating the vertical plate with a hydraulic rod and adjusting its tilt angle to ensure that the square hammer is directly above the pile hole. However, the above method lacks an auxiliary positioning mechanism, which leads to frequent fine adjustments to ensure that the adjustment is in place. This affects the adjustment efficiency and results in low adjustment performance and poor use effect. Therefore, there is an urgent need for an impact angle adjustment mechanism for the square hammer of the drilling pile driver to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention employs an auxiliary positioning mechanism consisting of an adjusting shaft, a level sensor, a servo motor, a detection plate, and a laser positioning device. When the impact angle of the hammer is adjusted via a hydraulic rod, the level sensor detects the levelness of the detection plate during the rotation of the upright plate. The servo motor drives the adjusting shaft to rotate, ensuring the detection plate remains level. This allows the laser point emitted by the laser positioning device to serve as an auxiliary reference for the operator, enabling adjustment of the hammer's position and angle based on the laser point. This ensures the hammer and the pile hole are aligned on the same axis, allowing for rapid and efficient adjustment and improving overall performance. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-3 As shown, the impact angle adjustment mechanism of the square hammer of the perforating pile driver in this embodiment includes symmetrically arranged supports 2, with a vertical plate 1 installed between the supports 2. Two sets of hydraulic rods 4 are symmetrically installed on one side wall of the vertical plate 1. The angle and orientation of the hammer block 8 can be adjusted by adjusting the inclination of the vertical plate 1. The fixed part of the hydraulic rod 4 is provided with a mounting seat 3. Both ends of the side wall opposite to the hydraulic rod 4 of the vertical plate 1 are provided with fixed seats 14. An adjustment shaft 10 is installed between the fixed seats 14. One end of the adjustment shaft 10 is connected to a servo motor 13, which can drive the detection plate 9 to rotate to ensure that it is always in a horizontal state. Two sets of detection plates 9 are symmetrically installed on the adjustment shaft 10. A laser positioning instrument 12 is fixed at the bottom center of each detection plate 9, which can provide auxiliary reference for the operator during the adjustment process. One set of detection plates 9 is equipped with a level sensor 11, which can detect the levelness of the detection plate 9.

Mounting holes are provided on both the mounting base 3 and the supports 2. The upright plate 1 and the hydraulic rod 4 are fixed on the corresponding bearing frame through the supports 2 and the mounting base 3. The hydraulic rod 4 drives the upright plate 1 to rotate, and the angle and orientation of the hammer block 8 can be adjusted by adjusting the inclination of the upright plate 1.

[0026] like Figures 1-3In this embodiment, the fixed base 14 is welded to the upright plate 1, the adjusting shaft 10 is rotatably installed between the fixed bases 14, the output shaft of the servo motor 13 is fixedly connected to one end of the adjusting shaft 10, the detection plate 9 is fixed on the adjusting shaft 10, the laser positioning instrument 12 is connected to the detection plate 9 by screws, the horizontal sensor 11 is connected to the detection plate 9 by screws, and the horizontal sensor 11 is electrically connected to the servo motor 13. When the impact angle of the hammer block 8 is adjusted by the hydraulic rod 4, during the rotation of the upright plate 1, the horizontal sensor 11 detects the levelness of the detection plate 9 and drives the adjusting shaft 10 to rotate through the servo motor 13 to keep the detection plate 9 always horizontal. This allows the laser point emitted by the laser positioning instrument 12 to serve as an auxiliary reference for the workers.

[0028] The specific implementation process of this embodiment is as follows: The upright plate 1 and hydraulic rod 4 are fixed on the corresponding bearing frame by the support 2 and the mounting base 3, and one end of the wire rope 7 is fixed on the winch. During use, the hydraulic rod 4 drives the upright plate 1 to rotate, and the angle and orientation of the hammer block 8 can be adjusted by adjusting the tilt of the upright plate 1. During the rotation of the upright plate 1, the level sensor 11 detects the levelness of the detection plate 9 and drives the adjustment shaft 10 to rotate through the servo motor 13 to keep the detection plate 9 always level. This allows the laser point emitted by the laser positioning instrument 12 to serve as an auxiliary reference for the workers. The orientation and angle of the hammer block 8 can be adjusted according to the laser point to ensure that the hammer block 8 and the pile hole are on the same axis. On the one hand, it can be quickly adjusted to the correct position with high adjustment efficiency, and on the other hand, it can improve its use effect.
