Description
Technical field
The present invention relates to tamping tool equipment technical field, specifically a kind of driving dress of the mobile tamping tool of more hammers
It sets.
Background technology
Coke-oven plant's tamping coking is that furnace coal is being entered stokehold using tamping machine tamping into the briquette for being slightly less than carbonization chamber,
Then it is pushed into coking in carbonization chamber.Heap density after briquette tamping can be improved by 700kg/m3~750kg/m3 of original bulk coal
To 950kg/m3~1150kg/m3.Production practices prove, using tamping coking compared with conventional top fills coking.Furnace coal matches
Coke strenth is promoted apparent when identical；When coke strenth is identical, coking coal, rich coal can be reduced in furnace coal using tamping coking
Amount of allocating, increase the amount of allocating of bottle coal.So can Reasonable Utilizing Its Coal Resources and apparent using TAMPING COKING PROCESS
Coke making and coal blending cost is reduced, apparent economic benefit and social benefit are generated.So ensureing tamping tool equipment availability, raising is set
Standby maintenance efficiency ensures that equipment operating efficiency is most important.
Tamping tool service efficiency includes the functional reliability and working efficiency (unit interval done make work(firm by ramming) of tamping tool.
In tamping coke furnace corollary equipment operation process, the time proximity device that tamping briquette is consumed in each cycle period operates
The 40% of total time-consuming.If tamping tool failure or maintenance and repair overlong time frequent occurrence, will all seriously affect coke oven production capacity.
The type of tamping tool is more, such as more hammer movable type tamping tools that tradition uses, and operation principle is that tamping hammer carries hammer
Action is mechanical transmission-type, is through speed reducer drive to eccentric wheel, to make the power of motor by being fixed on I-steel formula firm by ramming
Hammer the mutual grip friction effect of the friction plate and rotation wheel on two sides into shape, freely falling body is fallen after tamping hammer is mentioned level altitude
Under, realize the effect that briquette is made firm by ramming to compacting.Tradition, which is fiddled with, is both provided with sector gear in the drive shaft and driven axle of hammer, because of fan
Shape gear be vulnerable part, tooth lack certain amount or because catastrophic failure leads to gear failure when just need to change sector gear, again
It is not readily removable when being replaced after installation because the sector gear wheel hub of traditional design is to forge totally enclosed type, it need to be from one, axis by installation
Sequence is removed one by one, more install again after gear changing in place, maintenance time is long and maintenance time can not produce, not only time-consuming and laborious but also shadow
Ring yield；One end of sector gear, which also coordinates with racks cylinders, to be driven, and traditional rack cylinder piston rod top is milled with rack on one side,
After some cycles, because of constantly engagement collision between abrasion or two teeth, it is also easy to produce fall tooth phenomenon, when expense is not achieved in tooth
When, it is necessary to racks cylinders are replaced, cause to waste, cannot produce when replacing cylinder and cause production loss；Therefore, how simply,
Rapidly replace sector gear easy to wear and improve racks cylinders service life, to effectively shorten maintenance and repair when
Between, manufacturing cost is reduced, the production capacity of coke oven is improved, is those skilled in the art's technical problem in the urgent need to address.
