DJE130-V/H Omnidirectional High-Pressure Jet Grouting Drilling Rig

I. Product Features

1. Full-process online construction management system that automatically monitors and controls construction parameters. Suitable for a variety of complex geological conditions; adopts full rotation, semi-rotation, and full-angle rotation, and relies on vertical, horizontal, inclined, and other techniques to achieve multi-degree-of-freedom construction.

2. Torque monitoring: real-time monitoring of the grouting status to prevent the drill tool from seizing or twisting off in complex underground environments.

3. Displacement monitoring: precise adjustment of the power head's lifting distance.

4. Angle monitoring: enables full-circle, semi-circle, and arbitrary-angle sector swing jetting.

5. Speed monitoring: stable and uniform rotation speed is the prerequisite for ensuring uniform grouting.

6. Mechanical locking ensures the drill tool is clamped when no power source is input: it adopts a mid-drive method, and the five-jaw chuck uses an inclined wedge structure that can clamp the drill tool at any position. Compared with the top-drive method, the equipment height is greatly reduced.

II. Technical Parameters

III. Main Assemblies

1. Hydraulic transmission part, including the power source, control section, and actuators. Power is provided through the hydraulic system to achieve various actions and functions. All hydraulic components are required to be imported brands.

2. Electrical control part, including high-voltage control and low-voltage control. All electrical components use imported parts. It monitors and provides feedback on each action of the equipment, and adjusts each action through the feedback electrical signals to achieve automation.

3. Gearbox part: adopts a two-stage gearbox with a reduction ratio of i=5.6. The first-stage shaft of the gearbox is equipped with a speed-measuring element, and the bearings in the gearbox use tapered roller self-aligning bearings.

4. Rotation and traveling part, including the crawler chassis, frame, outriggers, etc.

5. Power part, including the five-jaw chuck mechanical locking mechanism, the five-jaw chuck hydraulic release mechanism, the power head lifting mechanism, and the hollow-shaft rotation mechanism.

6. Mast rotation part, composed of a slewing support bearing, jacking cylinder, and guide sleeve: it realizes full-machine rotation within a range of ±90°. Function: expands the machine's operational flexibility and space.

7. Safety protection facilities: safety guards and warning signs are provided for the equipment's moving parts, slewing spreader, working platforms, auxiliary facilities, and electrical devices.
