Depth 400m Hydraulic Water Drilling Machine Crawler Large Pneumatic

ST400 water well drilling rig:

* The series of drill rig adopts a excavator crawler chassis and has strong off-road performance. The independent module design allows the drill to be mounted on the truck to increase its mobility. Two speeds of rotating and advancing speed can meet the different needs of soil and rock drilling. Combined positioner, the positioning disc can be adjusted and replaced according to different types of drill pipe and impactor, so as to ensure the accuracy and reliability of the positioning and centering. The hoisting mechanism is convenient for hoisting of drill pipe and impactor, so as to reduce the labor intensity.
* This machine can be applied to various strata, used in water well engineering, geothermal well, anchor pile hole and so on, and can be used with follow-pipe drilling. It has the advantages of whole machine hydraulic control, automatic loading and unloading drill pipe, crawler type chassis, large horsepower diesel engine, four hydraulic support leg balance, stronger terrain application ability and so on.

Application scope and characteristics of drilling rig

Water well drilling rig is a light, efficient and multi-functional rubber tyred full hydraulic drilling rig with advanced structure and
It has the characteristics of convenient use and short auxiliary time. It is widely used in drilling water wells, monitoring wells and other exploratory hole projects, especially
The utility model is suitable for drilling air conditioning holes of ground source heat pumps in urban buildings. The drill adopts down the hole drilling with compressed air
Drilling in rocks with Proctor hardness f = 6-20 has a high drilling speed.

Host structure and working principle

1. Chassis rubber wheel chassis. Drag to walk.
2. The frame of frame welding structure is welded on the chassis. When the carriage is erected, it can be connected with the frame with bolts
As a whole, improve the rigidity of the carriage.
3. The carriage with welded structure adopts hot-rolled carbon channel steel and square steel pipe as the guide rail of the swivel head,
The oil cylinder is controlled to rise and fall smoothly through the one-way throttle valve. The verticality is controlled by the level and angle gauge on the console.
4. The slewing mechanism is composed of hydraulic motor and slewing reducer. Two high-performance low-speed high torque hydraulic horses
To drive the rotary reducer, you can obtain different torque and speed.
