Background technology
At present, with the continuous improvement of coal in China comprehensive mining machineryization injustice, overlength, heavy fully mechanized face transloading equipment
Use it is more and more extensive, pretension needed for drag conveyor, scraper blade elevating conveyor chain is increasing, traditional mechanical gear for conveyer
Chain tightener, individual prop, the chain tightener of oil cylinder and other modes are substituted by a kind of hydraulic tightener for motorcycle engine chain in succession.Hydraulic tightener for motorcycle engine chain is pacified
Loaded on the shaft coupling between drag conveyor parallel power portion's upper reducer and motor, by controlling fluid motor-driven to subtract
The straight-tooth drive parallel power portion shaft coupling of fast device realizes the tensioning of conveyor chain, and hydraulic motor leans on spring braking, and hydraulic pressure is released
Put and drive the tensioning and braking holding realized to conveyor chain.It is state-of-the-art chain tightener currently on the market.
It is well known that hydraulic motor is very high to driving medium requirement, it usually needs suitable specific hydraulic fluid could be realized
Normal phase normal operation.And producer is designed for convenience of period, usually high pressure breast used in hydraulic support is directly used in fully-mechanized mining working
Change liquid, and because emulsion pressure used in fully mechanized coal face is larger (being usually 31.5MPa), uses, emulsify after need to being depressurized by pressure reducing valve
Again usually because there is phenomena such as matching deficiency often using unit management problem in the proportioning of liquid concentration.Therefore tens of thousands of member
Hydraulic motor, often because of driving medium problem, spoilage is higher, and adds maintenance difficulty and labor intensity, substantially reduces equipment
Homes Using TV.
Influenced by fully-mechanized mining working emulsion quality, because the debris such as impurity in emulsion, bad sealing can often block and caused by
Valve group is operated to block, because the hydraulic motor of tensioning is, hydraulic pressure release, spring-loaded, by wearing piece and returns that liquid is not smooth etc. to be influenced,
Often result in that band-type brake is out of control, add danger injured when causing conveyer maintenance personal's chain link.
In conclusion when scraper conveyer chain tensioning at present disconnects chain, also can be completely achieved safety without one kind can
The chain tightener leaned on.In view of this, design and manufacture a kind of effectively realize effectively to be tensioned when drag conveyor disconnects chain, and letter
