TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, specifically relates to a building engineering piling device. BACKGROUND

[0002] Piling is a foundation construction method in building engineering, mainly used for driving or drilling piles into the ground to provide support and stability for structures. By driving piles into the deep underground, the load of the building can be transferred to more solid soil or rock, thereby improving the bearing capacity of the foundation. Moreover, pile foundations can effectively distribute the weight of the building and reduce uneven settlement of the foundation, ensuring the stability and safety of the building. At the same time, in soft or loose ground conditions, piling can significantly improve the stability of the foundation and prevent damage to the building due to soil sliding or liquefaction.

[0003] In the existing piling methods, the pile body is driven into the soil by hammering and vibrating methods. However, these two methods have the problems of high noise, low efficiency, and significant impact on the surrounding environment. Moreover, these two methods are mostly fixed, and when multiple piles are being driven, the device cannot be quickly moved. SUMMARY

Through the cooperation of the drill rod and the rotary blade, the drilling work is quickly performed, and the auxiliary assembly provides auxiliary power during drilling to reduce the resistance of the drill rod and the rotary blade during drilling. At the same time, the drill rod and the rotary blade are prevented from being blocked by foreign objects when they are separated from the ground.

[0008] The lifting module comprises lifting grooves symmetrically arranged on the moving base, first screws rotatably arranged in the lifting grooves, sliding blocks threadedly connected to the first screws, a bearing plate fixedly connected to the sliding blocks through support rods, and a brushless motor fixed to the bearing plate through a hydraulic push rod.

[0009] The lifting module controls the bearing plate connected thereto to move up and down, thereby adjusting the working height of the drill rod to adapt to the depth requirements of different pile bodies.

[0010] The side pushing module comprises a sliding groove, a second screw rotatably arranged in the sliding groove, a horizontal moving block threadedly connected to the second screw, a vibration exciter connected to the horizontal moving block through a damper, a synchronous motor arranged on one side of the sliding groove and used for driving the second screw to rotate, and an output shaft of the synchronous motor connected to one end of the second screw.

[0011] The side pushing module adjusts the position of the auxiliary component, the contact ring moves to contact the drill rod, the high-frequency vibration generated by the vibration exciter is guided to the drill rod through the guide rod and the contact ring, and in this way, the resistance encountered in the drilling process is reduced, and the resistance encountered when the drill rod and the rotary blade are lifted is reduced.

[0012] The support assembly comprises fixed blocks symmetrically arranged on the moving base, telescopic sleeves fixedly arranged on the fixed blocks and used for supporting the moving base, and telescopic arms slidably arranged in the telescopic sleeves.

[0013] The support assembly provides a stable foundation for the entire device, preventing tilting or displacement during operation.

[0014] Compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0015] 1. The brushless motor drives the drill rod to rotate, thereby effectively performing the drilling work, and the rotary blade fixed to the drill rod cooperates to effectively and quickly cut the soil, reduce the resistance during drilling, and improve the drilling efficiency.

[0016] 2. The first screw is driven by a rotating motor, and then the sliding block drives the load-bearing plate to slide up and down, so as to realize the height adjustment of the drill rod, so as to adapt to the drilling requirements of different depths.
