Steering core drilling device and method

Abstract

The invention discloses a steering core drilling device and method which achieve rotating of a drill bit at any angle. The problem of core drilling angle limitation in the prior art is solved, and theproblems that during core drilling in the prior art, the work condition of an operator is poor, and operation is difficult are also solved; and the steering core drilling device and method can achieve steering separation of the drill bit and a motor, the motor and the operator avoid ground mortar during core drilling, and safe operation is facilitated. According to the technical scheme of the steering core drilling device, the drill bit is included, and the drill bit is connected with a driving device through a steering separation device; the steering separation device is fixedly connected with a direction changing feeding device at the bottom of the steering separation device, and then is rotationally connected with a longitudinal feeding device, so that 360-degree rotation of the drillbit is achieved; and the direction changing feeding device is connected above the longitudinal feeding device, and feeding of the drill bit in any direction can be achieved.

Description

technical field [0001] The invention relates to the field of civil engineering and construction, in particular to a steering core drilling device and method. Background technique [0002] Traditional core drilling machines are generally suitable for horizontal core drilling, vertical core drilling, and oblique core drilling, but the maximum inclination angle is generally 45 degrees. When the core is drilled from the bottom of the component upward, the mortar ground out during the core drilling process will easily flow down into the motor and flow onto the operator. The working conditions are poor and the operation is difficult, which affects safe use. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a steering core drilling device and method, which can realize the separation of the drill bit and the motor, and can realize 360-degree rotating core drilling; the motor and the operator avoid The ground ...
