Working principle of winch:
The motor drives the steel wire rope drum through the reducer,
retracts and retracts the steel wire rope, and changes the
direction through different pulleys. The main process requirements
are drum speed namely the speed of wire rope movement and brake
system. Winch belongs to a relatively simple lifting or traction
machinery.
Winch (also known as winch/electric hoist), is a small and light
lifting equipment with a drum winding wire rope or chain to lift or
pull heavy objects. The hoist can lift the weight vertically, pull
it horizontally or obliquely. Winch is divided into manual winch
and electric winch two. Now mainly with electric winch.
Electric hoist is composed of motor, transmission mechanism and
drum or sprocket, divided into wire rope electric hoist and chain
electric hoist two.
Winch can be used alone, also can be used for lifting, road
construction and mine lifting machinery components, because of
simple operation, large rope winding, easy to move and application.
Mainly used in construction, water conservancy engineering,
forestry, mining, wharf and other materials lifting or flat tow.
Matters needing attention
Hoist has the advantages of large carrying capacity, stable and
reliable lifting and wide range of running speed, application, but
due to the lack of awareness and effective use of hoist safety,
often cause production accidents.
The hoisting machine is not fixed firmly and the ground anchor is
not set firmly, resulting in the displacement and overturning of
the hoisting machine.
There is no protective device on the drum to prevent the wire rope
slippage or the protective device is set up unreasonable and
unreliable, resulting in the wire rope from the winch.
The end of the wire rope is not fixed or fixed to the requirements,
resulting in the wire rope falling off.
The hoist brake is out of position.
The shaft fatigue fracture is caused by the inaccurate positioning
of the rope drum shaft end.
Installation position
1. Set up the operation shed, and ensure that the operator can see
the conductor and the objects dragged or hoisted. The construction
process of buildings, scaffolding and stacking materials,
components, etc. should not affect the driver's monitoring of the
whole process within the scope of operation. The roof of the
operating shed in the dangerous operation area should meet the
requirements of the protective shed.
2. The foundation is solid. Winch should be as far away from
dangerous operating areas as possible, choose higher ground, strong
soil, buried anchor with steel wire rope and winch lock, the front
should be piling, winch moving and overturning.
3. Drum direction. The drum is aligned with the center of the guide
pulley, and the distance from the drum to the guide pulley is: the
grooved drum should be greater than 15 times the width of the drum,
and the non-grooved drum should be greater than 20 times, so as to
prevent the wire rope from overlapping and the guide wheel flange
and wire rope wear when the drum is running.
