Principle of auger drilling machine
The main component of the auger drilling machine is the mast column of the drilling rig. The column is provided with a slideway and a gearbox that can slide up and down, and the gearbox is connected to the power The input shaft and the power output shaft, the other end of the power input shaft is connected with a hydraulic motor, the other end of the power output shaft is connected with a drill pipe, and the lower end of the drill pipe is connected with a drill bit. The up-and-down movement of the drill pipe of the drilling rig is realized by the drive device to the reduction box, which is more conducive to the rapid drilling with downward force; the reduction box can slide up and down along the slideway of the drilling rig frame to ensure the verticality of the drilling; the drill pipe is a spiral The blade drill pipe, the soil material can be returned to the ground along the blade when drilling; the power output shaft is a hollow mandrel, and the upper port of the mandrel can be connected to the concrete pouring equipment for concrete pouring.
Structure of auger drilling machine
1. Top pulley block: lifting power head and drill pipe drilling tool pulley block.
2. Power head: The three-ring deceleration mechanism is used to apply drilling pressure to the auger. Improve the stress condition of auger tools. With high load overload capacity, compact structure, low noise and long life, it is the most ideal power unit for domestic drilling rigs. It consists of two air-cooled motors, reducer, elbow, exhaust device, lifting frame and slider. When working, the two motors drive the high-speed rotation of the reducer through the coupling, and the power low-speed shaft drives the auger to rotate through the flange.
3. Auger drilling tool: The drilling rig becomes a lone L device. It is a helical drill pipe.
4. Hydraulic boom: the hydraulic device of the boom.
5. Control cab: The cab with various structures is controlled by the operator. It is located in front of the main winch at the rear of the drilling rig, and has an iron-shell structure. Windows are opened on three sides to ensure a wide field of vision.
6. Chassis: The device that supports the control room, the traveling mechanism and the slewing mechanism.
7. Walking mechanism: hydraulic walking type is adopted. When moving forward, the four outrigger hydraulic cylinders support the ground. Fold the outriggers down. The chassis is pulled forward through the contraction of the hydraulic cylinder, and the pile driver is realized through such repeated operations.
8. Rotary mechanism: driven by a medium-speed hydraulic motor through a reducer, under the cooperation of four outrigger hydraulic cylinders. The pile driver can be rotated 360 degrees.
9. Winding wire rope: the wire rope used by the windlass to lift the top motor, power head and auger.
10. Mast column: steel structure column. It is used to lift the top motor, power head, auger and hoisting cast-in-place pile reinforcement cage, with hydraulic lifting rod in the middle.
11. Hoisting winch: power device for lifting power head and auger, including motor and winch.
12. Hydraulic system: the assembly of all hydraulic devices of the drilling rig, including hydraulic pumps, hydraulic pipelines, etc.
13. Electrical system: electrical control device for the motor and power head on the top of the drilling rig.
