Abstract
The utility model provides a sprocket device with a changeable hub for a chain-and-bucket elevator of a mine. The sprocket device is characterized in that: a hub and a pinion of the sprocket are fastened by virtue of a bolt; a positioning groove of the pinion is formed on the hub; when the sprocket is arranged, the pinion is arranged in the positioning groove of the hub, the bolt is arranged, and the sprocket can start working; and when the sprocket is maintained, the bolt is detached, the sprocket can be maintained independently, and the hub can be changed. The sprocket device provided by the utility model has the advantages that: the device has a simple structure, maintenance and changing of the hub is convenient, and the sprocket maintenance cost is reduced.
Description
Affiliated technical field
The utility model relates to a kind of chain gear apparatus of replaceable wheel hub, especially a kind of chain gear apparatus of replaceable wheel hub of mine chain bucket elevator.
Background technology
At present, mine hoist of the prior art need be provided with large-scale derrick or headframe at well head, usually through motor; Steel rope, completion such as skip bucket straight up and down promote transport, because straight up and down lifting need be shut down conversion when replacing, so work efficiency is low; Shaft section is long-pending big in addition, so great in constructing amount, occupation space is also big; Its structure more complicated, Operation and maintenance are cumbersome, and cost is high.Mounting circular ring chain-drive bucket elevator can address the above problem, but will to solve this mine chain bucket elevator sprocket wheel volume big, the big and problem of repair difficult of weight.
Summary of the invention
In order to overcome the deficiency that existing mine chain bucket elevator exists, the utility model provides a kind of chain gear apparatus of replaceable wheel hub of mine chain bucket elevator, and this apparatus structure is simple, makes the maintain and replace of sprocket hub feasible.
The utility model solves the technical scheme that its technical matters adopted: hub of chain wheel and sprocket have the positioning groove of sprocket through bolted on the wheel hub, when sprocket wheel is installed; Sprocket is installed in the positioning groove of wheel hub; Hold-down bolt again, sprocket wheel just can be started working, during the maintenance sprocket wheel; With disassembling bolts, just can keep in repair and change wheel hub separately.
The beneficial effect of the utility model is, this apparatus structure is simple, and the maintain and replace wheel hub is convenient, has reduced the sprocket wheel maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the utility model.
The specific embodiment
Can find out that by Fig. 1 the utility model hub of chain wheel (1) and sprocket (2) are fastening through bolt (3), the positioning groove of sprocket (2) is arranged on the wheel hub (1); When sprocket wheel is installed, sprocket (2) is installed in the positioning groove of wheel hub (1), again hold-down bolt (3); Sprocket wheel just can be started working; During the maintenance sprocket wheel, bolt (3) is removed, just can be keeped in repair and change wheel hub (1) separately.
