Description

Technical Field

[0001] The utility model relates to the technical field of pile driver drilling, in particular to a spiral drilling device of a pile driver. Background Art

[0002] A pile driver is a pile-driving machine used for piling. During the construction process, a pile driver is usually used to drill holes in the ground, and then steel bars are embedded in the holes and concrete is poured to build a solid foundation pile. Common pile driver drilling methods include spiral, impact, grab, dry drilling, wet drilling and immersed tube drilling. Among them, the spiral drilling pile driver has been widely used due to its high precision, high controllability, wide range of applications and easy operation.

[0003] The spiral drilling pile driver mainly includes a spiral drill rod, a driving device, and a lifting device. When working, the driving device drives the spiral drill rod to rotate, and at the same time the lifting device drives the spiral drill rod to rise and fall, so as to transport the soil in the hole, thereby achieving the purpose of drilling. However, in the process of drilling holes in the ground, the traditional spiral drilling pile driver has a large construction noise, which is easy to cause noise pollution. In addition, when the spiral drill rod outputs the soil into the hole, it is difficult to control the falling direction and position of soil blocks, stones, etc., which is easy to injure operators or passers-by and vehicles, thereby posing a safety hazard. While outputting the soil, the soil on the spiral drill rod floats everywhere, which is easy to cause air pollution. Utility Model Content
