YDZ-1500/YDZ-2000/YDZ-2500The drilling rig is an electric rotary drilling rig. It is an ideal hole-forming machine for cast-in-situ piles. It reflects a multi-purpose new technology. Make the rig more usable and suitable for a wider range of formations. It is suitable for silt, clay, gravel layer, weathered rock shale, and more suitable for foundation construction of a variety of complex layers such as pebbles. Ideal equipment.

Drill Structure and Operating Principle:

1. YDZ-2500 multi-function drilling rig is composed of electric motor, reducer, vacuum pump, hydraulic oil pump, main winch, auxiliary winch, oil cylinder, power distribution box, drill frame, drill rod, drill bit.

2. Motor: Y series ordinary motor.

3. Reducer: The drilling rig is reduced to four-axis three-stage gear.

4. Sealing: When the rig is working in a sandy or muddy environment, it must be ensured that it cannot leak air and oil before it can work normally. Therefore, this machine uses a combination of mechanical seal and packing.

working principle:

1. The drilling rig's walking and steering are delivered by the oil pump to the traveling oil cylinder and steering oil cylinder through the pipeline. It is controlled by the multi-way valve, so that it can complete the forward, backward, step-type walking and left-right steering action.

2. The power unit transmits the power to the output shaft through a speed reducer through a speed reducer, which drives the drill pipe and drill bit to cut the soil. The cut mud is discharged from the drill pipe hole into the slurry pool by the mud pump. The sludge enters the circulation after passing through the sedimentation.

Cage and ash pouring of drilling rig

After the pile hole is drilled, the drill rod and drill bit are raised, and the rig moves one step backward at the same time. Use the auxiliary forehead hook above the drill rig to align the center of the pile hole, and the hoist can be used to pour the cage and commodity ash.
