The main structure of the drilling rig

1, car chassis: the chassis of the truck as the walking mechanism of the drill, according to the research and development and design requirements of the rotary drilling rig. 2, hydraulic support device: the use of radial leg bearing rotary drilling rig. The outrigger has a total of eight hydraulic cylinders. After the horizontal hydraulic cylinder is extended, the vertical hydraulic cylinder drives the outrigger to support the ground with good stability. In the lifting operation, all the load does not pass through the frame but directly acts on the leg, can reduce the frame bearing and reduce the height of the center of gravity, in order to protect the chassis from damage. 3, control, control system: control, control mechanism is mainly composed of a variety of hydraulic valves, solenoid valves and joystick hydraulic system, installed in the transparent copilot. 4, main, pay hoist structure: main hoist for drilling pipe, drilling tool lifting. After the vehicle-mounted rotary drilling rig is in place, the main hoist releases the wire rope, so that the drill pipe drives the drill tool down along the column track. After hitting the ground, the power head drives the drill bit to drill. After the drill bit is filled with soil, the main hoist and reel the wire rope, and the drill pipe and drill bit are put out of the hole for unloading. The main function of winding is to cast the steel cage into the hole after drilling. At the same time, winch can lift materials, if no additional winch can also achieve simple lifting. 5, rotary and adjustment mechanism: through the rotary mechanism rotary fine-tuning and adjusting mechanism before and after the pile hole, about 90 degrees of rotation for unloading operation. 6. Power head: The power head drives the drill bit and is the key working component of rotary drilling. When the power head drives the bit to rotate, different bits can be changed according to different geological conditions to meet the requirements of various working conditions. This product can deal with hard stratum without pressurization by vibration and impact, and quickly enter into rock. At present, this technology belongs to the first one in China, and the impact device adopted is introduced from abroad. 7, drill pipe and drill bit: telescopic drill pipe is the main working parts of the car rotary drilling rig, through the telescopic mechanism set together, in order to extend the depth of drilling, telescopic drill pipe form is also very unique, is independently developed by our company and used in this product. There are many kinds of rotary drilling mechanism drilling, different drilling tools are suitable for different geological environment, mainly short auger bit, rotary bucket, core bit, reaming bit, etc..
