The deviation of the electric winch during operation may be caused by various reasons such as mechanical failure, electrical failure, improper operation, and environmental factors. The following is a specific analysis:

1、 Mechanical malfunction

Abnormal noise and looseness of the drum

Loose bolts on the drum shell, excessive clearance between the drum shell and the supporting wheel, or cracks on the drum shell may all lead to unstable winch operation and deviation.

The loose fixing screws between the traveling drum and the liner cause relative sliding between them, which can also affect the normal operation of the winch.

Uneven arrangement of steel wire ropes

The tangled steel wire rope on the drum will accelerate the wear of the steel wire rope, and even cause the steel wire rope to slide out of the drum, resulting in the deviation of the winch operation.

Improper arrangement of the winch (such as lifting the steel wire rope at an angle that does not meet the specified requirements), lack of oil in the winch pulley (guide wheel), failure or removal of the winch rope arrangement device, improper operation and loose winding, etc., may all lead to uneven arrangement of the steel wire rope.

Gearbox malfunction

The abnormal noise and vibration generated during the operation of the reducer may be caused by the gear mesh clearance being too tight or too loose, the bearing clearance being too large, the reducer or bearing bolts becoming loose, or foreign objects falling into the reducer.

These faults will affect the transmission efficiency of the winch, leading to unstable operation of the winch.

Brake system malfunction

Malfunctions such as brake overheating, insufficient braking torque, and ineffective braking may be caused by premature, excessive, or forceful use of the brake, loose or excessively worn brake shoe bolts, or incorrect installation of brake shoes and brake wheels (or discs).

Brake system failure can seriously affect the safe operation of the winch, resulting in deviations during operation.

2、 Electrical malfunction

Motor failure

Malfunctions such as motor not turning or single-phase operation of the motor may be caused by power supply failures (such as power outages, phase breaks, motor or line grounding), failure to reset the stop button, internal faults in the starter, or broken operating cables.

Motor failure can affect the power output of the winch, leading to unstable operation of the winch.

Control button malfunction

Malfunction of operation buttons, excessive humidity, short circuit of operation wires, or grounding faults can cause the winch to fail to start or stop normally, affecting the stability of winch operation.

3、 Improper operation

Lack of operational experience

The lack of concentration and operational experience of winch operators may lead to deviations in the operation of the winch.

For example, if the over roll switch fails and the operator fails to detect and take measures in a timely manner, it may cause the mining car to rush to the front of the wheel before stopping, resulting in an accident.

violation of operating rules

Violation of regulations (such as using endless ropes to tow off track mining cars for re tracking) may result in damage to the steel wire rope due to impact force, bury potential safety hazards, and affect the stability of the winch operation.

4、 Environmental factors

roadway deformation

The deformation of the roadway and the bulging of the bottom cause the support to be misaligned, resulting in the deflection of the rollers, which may cause the conveyor belt to deviate and thus affect the stability of the winch operation.

Although this factor is more related to the conveyor belt system, tunnel deformation may also indirectly affect the layout and operating environment of the winch.

Dust and moisture

Dust and humid environments may affect the normal operation of electrical equipment, leading to an increase in electrical failures and subsequently affecting the stability of winch operation.
