Document Type and Number:
WIPO Patent Application WO/2018/095321
Kind Code:
A1
Abstract:
An automatic positioning device and method for a big arm of an umbrella driller. The device comprises a rotating arm (1) connected to a standing column (20), a supporting oil cylinder (2), a big arm (3), a verticality adjustment oil cylinder (4), a slip support (5), a drill arm (6), and a big gear wheel (7). A hydraulic motor (8) is disposed on the rotating arm (1), and an output end of the hydraulic motor (8) matches the big gear wheel (7). One end of the big arm (3) is connected to the rotating arm (1), and the other end of the big arm (3) is connected to the slip support (5). The tail end of the supporting oil cylinder (2) is connected to the rotating arm (1), and a telescopic end of the supporting oil cylinder (2) is connected to the big arm (3). The tail end of the verticality adjustment oil cylinder (4) is connected to the big arm (3), and the telescopic end of the verticality adjustment oil cylinder (4) is connected to the slip support (5). The drill arm (6) is connected to the slip support (5).The supporting oil cylinder (2) is in series connection with the verticality adjustment oil cylinder (4). The device is simple to operate, and accordingly the working difficulty is reduced and the working efficiency is improved; the method has a high precision, the dimensional orientation of a shot hole coincides with a theoretical design, and an ideal blasting effect is achieved, thereby ensuring the safety of workers, and reducing construction costs.
