Head Sheave And Guide Wheel Castings And Forgings Suitable For
Mining Hoist
1. Product description of head sheavel and guide wheel, castings and forgings
On the premise that the guide wheel device can be transported as a
whole, the traveling wheel and the fixed wheel adopt the whole
casting welding structure. The wheel hub and rim are cast steel
materials, and the spokes are channel steel. After welding, the
whole annealing process can be carried out.
In consideration of the convenience of replacing the bearing bush
for maintenance, there is room for replacing the bearing bush for
disassembly, and the guide wheel device adopts eccentric
arrangement.
The guide wheel shaft is integral forged of medium carbon alloy
steel, with cast-welded roof wheel, equipped with PVC or nylon
liner to protect the wire rope. Imported (or domestic) spherical
roller bearings, bearing temperature measuring elements can also be
installed.

3. Common faults and techniques of Head sheaves and guide wheels
castings and forgings
(1) For the burning tile problem of old structure Head head sheave
sliding bearing, the lubrication mode should be improved; Because
the crown wheel is installed on the derrick, it is inconvenient for
daily maintenance, temperature alarm signal device should be added
to timely maintain and prevent burning tile accident, or replace
the original sliding bearing with rolling bearing structure.
(2) For the old structure of the pulley without padding in the rope
groove, no padding can be added on the original rope groove, so it
is necessary to replace the pulley with padding, and the adjacent
assembly size can be kept unchanged to facilitate installation;
(3) For the mines with difficult transportation in mountainous
areas or underground roadways, the crown wheel (guide wheel) can be
replaced with a two-half structure or four-half structure.
