The specific steps for improving emulsion hoist are as follows:

preparation:

Equipment inspection: Confirm that the mechanical structure of the emulsion hoist is complete and all components are undamaged. Focus on inspecting key components such as emulsion motor, gear transmission mechanism, braking unit, and chain.

Confirm the medium: Ensure that the emulsion supply is sufficient and meets the equipment requirements. Emulsions need to have fire-resistant and explosion-proof characteristics to adapt to special environments such as coal mines underground.

Cleaning up the environment: Keep the work area clean, remove obstacles, and ensure that the lifting passage is unobstructed.

Start device:

Connect power supply: According to safety regulations, connect the main power supply of the emulsion hoist.

Start motor: Operate the control device to start the emulsion motor. The motor is driven by emulsion and outputs power to the gear transmission mechanism.

Check operation: Observe the operation of the motor and gear transmission mechanism to confirm that there are no abnormal noises or vibrations.

Adjust torque and speed:

Gear transmission: The motor output shaft is adjusted to the appropriate torque and speed through a three-stage fixed axis gear transmission reduction mechanism. Reasonable backlash should be set between gears to control transmission resistance torque and starting noise.

Braking inspection: Install ratchet and pawl structures as braking units between the first and second gear transmission pairs. Before operation, it is necessary to confirm that the braking unit is working properly to ensure safety.

Lifting operation:

Connecting sprocket: The output end of the reduction mechanism is connected to the ring chain sprocket through a rectangular spline. Operate the control device to rotate the sprocket forward and backward, achieving the up and down movement of the chain.

Mounting heavy objects: Connect the lower hook on the chain to the heavy object to form a double chain structure with a movable pulley. After confirming that the connection is secure, lifting can be carried out.

Smooth lifting: Slowly operate the control device to lift the heavy object smoothly. Avoid overloading the equipment or shaking heavy objects due to rapid lifting.

Operation monitoring:

Observation of operation: During the lifting process, closely observe the operation of the emulsion hoist. Pay attention to the working status of the chain, sprocket, and brake unit to ensure that there are no abnormalities.

Adjust speed: Adjust the lifting speed according to actual needs. Avoid emergency stop or steering operations during high-speed operation to reduce equipment wear and tear.

Descent and uninstallation:

Steady descent: Operate the control device to smoothly descend the heavy object to the designated position. Avoid rapid descent that may cause heavy objects to impact the ground or damage equipment.

Unloading heavy objects: After confirming that the heavy object has landed stably, loosen the connection between the lower hook and the heavy object. Raise the hook to a safe height and prepare for the next lifting operation.

Shutdown and maintenance:

Shutdown operation: After the lifting is completed, turn off the emulsion motor and cut off the main power supply. Park the emulsion hoist in the designated location to ensure equipment stability.

Daily maintenance: Regularly inspect and maintain the emulsion gourd. Including cleaning equipment, checking gear wear, replacing emulsions, etc. Ensure that the equipment is always in good working condition.
