Abstract

The invention provides a power head device and system and a control method. The power head device comprises a lifting basket outer frame, a push-pull assembly, a power head assembly and connecting assemblies. One end of the push-pull assembly is connected with the top of the lifting basket outer frame. The other end of the push-pull assembly is connected with the power head assembly. The power head assembly comprises a power head body arranged in the lifting basket outer frame and a power head drill bit outwards extending to the bottom of the lifting basket outer frame. The two sides of the power head body are slidingly connected with the inner wall of the lifting basket outer frame so that the power head body can rise or fall in the lifting basket outer frame. The connecting assemblies are arranged on the outer walls of the two sides of the lifting basket outer frame and used for being connected with locking structures on a truss. The power head device provides sufficient and stable feeding force, conveniently and rapidly performs drilling and is high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a power head device, a power head system and a control method. Background technique [0002] High-pressure rotary jet grouting is to rotate and lift the spray rod with nozzles at the bottom after reaching the deep underground, and pump high-energy fluid and cement slurry at the same time to form isolated or regularly arranged cylindrical columns underground. Process of cement-soil consolidation. In order to reduce costs and improve efficiency, in recent years, self-forming holes are often used in the link of how to send spray booms underground. [0003] At present, there are three methods of self-forming holes for high-spray grouting: gravity pressure, oil cylinder chain pressure and full chain pressure. [0004] Among them, the gravity pressure method is to use the self-weight pressure of the power head to drill downward. When encountering a hard stratum, the spr...
