The explosion-proof diesel engine monorail crane locomotive is mainly composed of a cab, a drive unit, a diesel engine main engine, a cooling unit, a speed protection trolley, a load-bearing trolley, a pull rod, a lifting beam, etc.
Main components
Swing arm semi-motor drive device
The swing-arm semi-motor drive unit consists of a hydraulic semi-motor, travel wheels, friction wheels, brakes, left and right swing arms,and a clamping cylinder.
It uses a swing-arm support structureconnected to the friction wheels via an intermediate short shaft. It has a rated traction force of 30 kN and is equipped with a working brake and a safety brake, both with a braking force of 45 kN.
Full motor drive
The full motor drive unit consists of a hydraulic full motor, travel wheels, friction wheels, guide wheels, brake devices, clamping cylinders and valve groups.
The hydraulic full motor is directly connected to the friction wheels. The advantages of this drive unit are simple structure and easy maintenance. It is equipped with a working brake and a safety brake, and the braking force is 45kN.
Host
The main engine consists of an explosion-proof diesel engine, a closed variable pump, a water wash tank, a hydraulic oil tank, a fuel tank,a diesel engine cooling system, and an automatic fire extinguishing device.
The accompanying explosion-proof diesel engine meets China III emission standards and can be safely used in high-gas and dusty environments underground.
The engine is compact, has a large torque reserve, and delivers constant torque output at low speeds.
The hydraulic parts are imported brands with high reliability. The main pump adoptsDAThe closed-loop hydraulic system ensures smooth operation and minimal pollution.
Electro-hydraulic control and fully hydraulic braking enable continuous, direct transport from the surface or pit yard to the mining face over long distances. Equipped with an automatic fire extinguishing device, it detects temperature and triggers the device for automatic fire extinguishing.
A manual trigger is also available for manual activation.
Diesel engine monorail crane cooling device
The cooling device consists of a cooling box frame, a hydraulic oil air-cooled heat dissipation system, and an electrical control system, and is generally suspended below the drive unit.
Translational semi-motor drive device
The translational semi-motor drive device consists of a hydraulic semi -motor, roller bracket, travel wheel, friction wheel, guide wheel, brake device, clamping cylinder, etc.
The translational semi-motor adopts a translation bracket structure, connected by an intermediate long shaft with a friction rated traction of 30KN, and the braking force of the brake is greater than 45KN.
