Basic composition
The core drill is composed of rotary mechanism, feeding mechanism, lifting mechanism, transmission mechanism, control device, base and other basic parts. Due to different types of drilling rigs, some core drilling rigs may also be equipped with control measuring instruments or other accessories.
The rotary mechanism of the drilling rig is called rotary device, which is used to drive the drilling tool to rotate and realize the continuous rock breaking of the drill bit. There are three types of gyrators of core drilling rig: vertical shaft type, rotary table type and mobile type. The classification of core drilling rig comes from this.
The lifting mechanism is used to lift the drilling tool, casing or other things. Most drilling rigs are specially equipped with lifting mechanism, which is generally called "elevator", while some drilling rigs are not equipped with lifting mechanism. For example, in mobile rotary drilling rigs, the function of elevator is realized by the cooperation of power head and feeding mechanism.
The feeding mechanism is used to adjust and maintain the axial load on the drill bit at the bottom of the hole, and feed the drilling tool according to the drilling speed of the drill bit to keep the drill bit drilling continuously.
The transmission mechanism is used to drive the power transmission from the power machine of the drilling rig to each working mechanism of the drilling rig. The power transmission mode of drilling rig includes organic transmission, semi hydraulic transmission and full hydraulic transmission.
The control device is used to distribute power, adjust the movement speed of each working mechanism of the drilling rig, and change the movement direction and form of the working mechanism. The operating mechanism of mechanical transmission drilling rig is generally set together with relevant components, while the operating mechanism of hydraulic transmission drilling rig is mostly set together as an independent component, which is called console.
purpose
The core drilling rig is mainly used for the general survey and exploration of metal and non-metallic solid minerals. In addition, it can also be used for engineering geological exploration, hydrogeological investigation, general survey and exploration of oil and gas fields and water well drilling.
