Its design structure is simple, and wheel hub is designed as weldment, can either guarantee the normal work of head sheave, also can reduce entire head sheave
Weight, reduce enterprise's production cost.
The technical scheme adopted by the utility model is a kind of wheel hub structure for mine hoist head sheave, including phase
Mutual symmetrical two groups of semicircle hub units, two groups of semicircle hub units assemble to form wheel hub, every group of semicircle hub unit
Include two shapes semicircular plate identical with size, there are gap between two semicircular plates, is provided at least in gap
Two link blocks, link block are welded with two semicircular plates respectively, are welded with semicircle on the lateral surface of two semicircular plates
Stiffening plate, stiffening plate outer diameter is less than the outer diameter of semicircular plate, and the center of circle and the semicircular plate center of stiffening plate coincide, two and half
It is arranged in the gap of circular slab there are two the bolt mounting rod being parallel to each other, the center of bolt mounting rod, which offers, to be bolted
Hole, two groups symmetrically semicircle hub unit be attached by the bolt being mounted in bolt connecting hole.
Key block is fixedly installed on link block between two semicircular plates of wherein one group of semicircle hub unit.
The bolt mounting rod is welded to each other with semicircular plate.
When work, two groups of semicircle hub units assemble to form circular wheel hub, in the semicircular plate outer surface of wheel hub
Spoke is installed, the end of spoke connects wheel rim, that is, can be assembled into the head sheave of elevator, due between the semicircular plate of wheel hub there are
Certain gap can reduce the total quality of wheel hub, and when being applied in the head sheave that diameter is 4m, the overall weight of head sheave can be with
16-17t is dropped to from 25t, effectively reduces the overall weight of head sheave.
Described includes two groups of symmetrical semicircle hub units, and two groups of semicircle hub units assemble to form wheel hub；
The purpose being arranged in this way is: can be replaced when a semicircle hub unit is damaged wherein, be avoided entire
Wheel hub is scrapped；Such structure design is more convenient for producing and processing simultaneously, reduces production difficulty, shortens the production cycle.
Every group of semicircle hub unit includes two shapes semicircular plate identical with size, two semicircular plates
Between there are gap, at least two link blocks are provided in gap, link block is welded with two semicircular plates respectively, in this way setting
Purpose be: two semicircular plates are attached by link block, ensure that and also utilize gap shrinks wheel hub while intensity
Overall weight.
Semicircular stiffening plate is welded on the lateral surface of described two semicircular plates, stiffening plate outer diameter is less than semicircle
The outer diameter of plate, the center of circle and the semicircular plate center of stiffening plate coincide: the purpose being arranged in this way is: to increase hub centre
Working strength reduces damaged probability, is conducive to extend the service life of wheel hub.
It is arranged in the gap of described two semicircular plates there are two the bolt mounting rod that is parallel to each other, in bolt mounting rod
The heart offers bolt connecting hole, two groups symmetrically semicircle hub unit connected by the bolt being mounted in bolt connecting hole
It connects；The purpose being arranged in this way is: after every group of semicircle hub unit is assembled, using bolt by two semicircle wheel hub sets
Part carries out conjunction to form wheel hub.
The utility model has the following beneficial effects: the utility model design structure is simple, wheel hub is designed as weldment, it can
The normal work for enough guaranteeing head sheave, also can reduce the weight of entire head sheave, reduce enterprise's production cost.
