Crawler Mounted Drill Rig introduction
ST180 Profile steel crawler pneumatic well drilling rig is a light, multifunctional drilling equipment. It is characterized by advanced structure, convenient use, high operation efficiency, reliability and durability. It is widely used for drilling wells, agricultural irrigation wells, geothermal air conditioning holes and other uses, especially for water intake projects in mountainous areas and rock strata. The new hydraulic technology is adopted in the drilling rig, which is equipped with large torque hydraulic motor rotation and large bore hydraulic cylinder propulsion. The labor intensity is greatly reduced, the auxiliary time is shortened, and the construction efficiency and engineering quality are improved.

System composition of well drilling rig
1, Power system is the equipment that provides energy for the whole rig.
2, Working system, equipment that works according to process requirements.
3, Transmission system, for the working system, transport, distribution of energy equipment.
4, Control system, equipment to assist the main system.
5, Auxiliary system, equipment to assist the main system.
Structure and working principle of dewatering well drilling rig
1, The structure of the whole machine is mainly composed of operating platform, grinding plate (or power head), seat frame, water pump, flap door, pipe unloader, column, drilling tool, etc.
1. The operation platform is used to control the action of various components of the hydraulic system and realize the normal operation of the drilling rig. The operation platform is composed of bench, multi-channel directional valve, counter flow valve, gear pump and hose.
2. The power head consists of motor, reducer, chuck, etc. It is mainly a mechanism that converts power into mechanical energy. The gear box is equipped with a gear handle, which can realize the rotation speed of the drill pipe,
3. The underframe is used to support the power head, and the propulsion cylinder drives the power head to drill the tower to move back and forth. It can also adjust the flatness of the whole rig, so that the rig can work normally in any terrain.
