Head sheave / hoisting sheave / sheave pulley / guide pulley for mine hoist Product Introduction Guide wheel device can transport the whole under the premise of swimming round and fixed wheel adopts integral cast joint structure, wheel hub, wheel rim for cast steel materials, spoke for the channel steel, after welding the whole annealing process again.
Guide shaft using middle carbon alloy steel forging whole, adopting the structure of the cast joint pulley, equipped with PVC or nylon liner, protect the wire rope.
Imported or domestic spherical roller bearings, also can install bearing temperature measuring element.
In order to prolong the service life of wire rope, rim inside wedge liner with wear-resisting, withstand voltage, using D660 (1010) or nylon liner.
1) eccentric layout: on one side of a winding wheel have replaced bearing dismantling space, can not remove the pulley mechanism, only for bearing maintenance and replacement.
2) symmetry layout: relative with four wheels on both sides of the two bearing seat is symmetrical, but need to replace the bearing shell, only to remove the pulley mechanism.
sheave pulley and the common malfunction and technical guide wheel
1) to the problem of old structure pulley sliding bearing to burn tile should improve lubrication way; Because of the pulley is installed on the derrick, daily maintenance inconvenience, should add temperature alarm device, so as to timely maintenance to prevent the tile burning failure, or the original sliding bearing replacement into rolling bearing structure
2) for old structure pulley rope groove without liner, can no longer add padding on the original rope groove, need to change a gasketed pulley, adjacent assembly size can remain motionless, and installation
3) for mountain transportation difficulties or have some difficulties in roadway transportation in underground mine, the pulley is (guide wheel) change the structure into two or four and a half of head sheave.
