Description

Adjustable Angle Low Headroom Drilling Tools

technical field

The utility model relates to the technical field of piling equipment for construction, in particular to a drilling tool with adjustable angle and low headroom.

Background technique

The auger drill is a piling equipment that drives the auger drill bit into the ground to form a hole through the power head. For example, the long auger and the cement mixing pile machine all use the auger. At present, the power motor of the auger drilling tools on the market is driven up and down by a wire rope lock. This setting requires the gravity of the power motor itself to slide down and then the drill bit to complete the drilling. This setting leads to a higher pile frame and insufficient stability. Especially in soft soil, it is easy for equipment to tilt and collapse, resulting in construction safety hazards. When used for a long time, the support plate under the supporting hydraulic rod may warp to the four corners, which makes it difficult to achieve the fixing and supporting functions. In addition, it is not suitable for construction in special narrow and low spaces, such as bridges, culverts, building interiors, workshops, subways, municipal pole and line facilities, etc. Large and high pile frame equipment is not suitable.
