Description
Technical field
The present invention relates to mining transportation apparatus field, especially a kind of scraper conveyor tail chain tightener.
Background technology
The drag conveyor conveying equipment important as coal working face, its reliable, safe efficient operation is to coal mine
Production efficiency and the economic benefit important of enterprise.With the increase of coal mining amount, drag conveyor must lead to
Increase laying length is crossed to increase conveying capacity.Haulage gear of the scraper chain as drag conveyor needs to bear in the course of work
Prodigious load.In addition scraper chain is not absolute rigid body, the effect of load can make scraper chain deform and extend, when long
Between accumulation after will lead to the loosening of scraper chain.If be tensioned not in time to the scraper chain of loosening, it will occur chain, card
The problems such as chain, chain rupture, and then influence the production of working face.Therefore it is necessary tight chain to be carried out to drag conveyor in time.
Data shows that there are two types of the tight chain modes that China mainly uses at present：Artificial tight chain and hydraulic pressure automatic tight chain.Manually
Tight chain is to block and remove the tight chain side of wherein a few pitch chain items manually in the case where worker has found that apparent loosen occurs in scraper chain
Formula.The tight chain method efficiency is low, and labor intensity is big, and artificial tight chain process middle scraper machine must be shut down, and be seriously affected
Working efficiency.Hydraulic pressure automatic tight chain realizes the tensioning to scraper chain, this method in such a way that Driven by Hydraulic Cylinder tail is flexible
It can theoretically achieve the effect that auto-tensioning, but since conditions down-hole is severe, hydraulic control component is easy failure, actual use
The effect is unsatisfactory.In addition the tight catenary system of hydraulic pressure is complicated, and purchase cost and maintenance cost are higher, so in middle and small scale coal mine
It is not promoted preferably.

On, it is keyed with steering sprocket in the middle part of steering sprocket axis, is symmetrically installed multifunctional wheel in steering sprocket both sides, multifunctional wheel passes through
Bearing is mounted on steering sprocket axis and steering sprocket shaft rotation can move relatively, and the multifunctional wheel side is gear, and the other side is
Sprocket wheel, adjustment axis be parallel to steering sprocket axis setting, adjustment axis both ends by bearing be mounted on bearing block B on, regulation handle with
Wherein one end of adjustment axis is connected, and position corresponding with the sprocket wheel of multifunctional wheel, which is equipped with, in the middle part of adjustment axis adjusts sprocket wheel, adjusts
Pitch chain wheel is keyed with adjustment axis, and the sprocket wheel for adjusting sprocket wheel and multifunctional wheel is connected by chain, the gear lower part of multifunctional wheel
It is engaged with rack, and latch segment is set in the wheel and rack engagement place of multifunctional wheel, rack is fixed with sliding rail, the sliding rail
On be provided with dovetail groove, in dovetail groove be equipped with sliding block, the bearing block A and bearing block B are each attached on sliding block.
Further, the sliding rail is fixed on aircraft tail shelf.
Advantageous effect：(1) device is by rotation of the rotation with movable sprocket of regulation handle, to by power transmission to more
On function wheel, and the movement of the transmission realization steering sprocket axis by rack-and-pinion, it is finally reached tight chain purpose, transmission parts are left
Right both sides are arranged symmetrically, and avoid the tensioning nonsynchronous problem in left and right, and whole device uses purely mechanic transmission, and cost is relatively low, can
By property height, and it can avoid the Leakage that hydraulic cylinder tension band comes；(2) device is locked using latch segment, in tight chain
After completion, latch segment is inserted into wheel and rack engagement place, front and back each one piece, realizes locking function, this mechanical lock
It is more safe and reliable；(3) chain tightener is regarded an entirety by the present invention, only need to be on the basis of existing drag conveyor to machine
Tail portion slight modification makes steering sprocket and multifunctional wheel share a steering sprocket axis, and outputs one on the aircraft tail shelf of right side
Strip slot, you can this device is fitted into drag conveyor and is used, the lowest point of the device is with highest point without departing from original
The travelling route of scraper plate does not interfere the normal work of drag conveyor；(4) the especially suitable tail of the chain tightener does not drive only
The Double chain scraper conveyor of China for realizing turning function, it is small to the transformation of former drag conveyor, using purely mechanic transmission, need not control
System participates in, simple in structure, at low cost, has extensive practicability.
