Structure of Water Well Drilling Rig

1. Hydraulic oil pump: it is a duplex type. The large displacement pump provides power for the power head, and the small displacement pump provides power for four outrigger cylinders, landing mast cylinders, and afterburner/lifting pulley cylinders. 2. Four outriggers: small drilling equipment consists of hydraulic oil cylinder and fixed frame. The levelness of the body can be adjusted at the work site to support and stabilize the body.

3. Mast: It is a frame structure welded by the combination of giant steel pipes, channel steel and angle steel. The inner groove of the channel steel on both sides is used as the track for the power head to run up and down to ensure the verticality of the drilling hole. The lifting and lowering of the drilling mast is completed by the hydraulic cylinder.

4. Power head: gear reducer mechanism is adopted, and its low speed shaft has a large hole mandrel in the middle. The upper mouth of the mandrel can be connected with the rubber pipe interface of the concrete pouring equipment to pour concrete; The lower end of the mandrel is connected with the drill pipe and drill bit through a flange. The high-speed shaft is driven by a high-torque hydraulic motor.
