Description
Technical field
This utility model is related to the adjusting apparatus of electric-motor drive belt, particularly a kind of driving belt take-up device, energy
Enough elasticities conveniently and efficiently adjusting electric-motor drive belt, are particularly suited for adjusting the elastic of motor of oil extractor driving belt
Degree.
Background technology
In operation process, motor imparts power to quadric chain by belt to beam pumping unit, realizes taking out
The normal production of oil machine.Adjustment and change the main contents that electric motor belt is always oil pumper maintenance, changes belt, tight
Belt, travel motor is simultaneously fixing, ensures that the elastic appropriateness of belt, four points one lines are to extend belt service life, improves and recover the oil
When rate important measures.Frequently shut down adjustment motor, that is, the workload that increased oil recovery work have impact on crude output again.Mesh
The front adjustment to motor of oil extractor belt tightness degree, mainly manually experience controls, and is displaced outwardly motor, holds out against belt
Time long, waste time and energy, and manually control the elasticity tension generally of belt.Tension on electric motor belt, makes
Become transmission resistance big, runtime efficiency reduces by 1.2% about, unit consumption rising 0.1kW h/t, and equipment fault easily, often
All there is reduction box, bearing of motor abrasion fault year, economic loss is huge.There is one kind belt top-fastener at present, be from skin
Hold out against below band, because belt inner surface is boss type, belt outer surface is plane, easily cause belt and break stock, abrasion belt breaks
Split.
Drive motor and belt adjust uncomfortable and following reasons and can affect oily well yield：
1st, because the frost mist weather that rains causes belt pulley and belt engaging surface to skid, the jig frequency of reduction oil pumper, especially under
When raining heavyly, the jig frequency of oil pumper can reduce by 0.03 0.07r/min.
2nd, in order to prevent electric motor belt serious wear from causing, fracture stops well and long the fluffing of belt run time used is beaten
Sliding, once find to shut down in time to carry out changing belt or tight belt.Change belt and the time used by tight belt is close, all used times
Long, especially sand output well is shut down and adjustment time is long, it will causes sand card to lie well, is unfavorable for oil well production.Belt tension
Degree adjustment is improper, causes transmission slip also unfavorable to bearing of motor.
Content of the invention
The purpose of this utility model is to provide a kind of driving belt take-up device, during for rod-pumped well, can accomplish not
Stop well, Quick fastening belt.Mitigate and beated the phenomenon that throws switch due to belt pine, the belt slippage causing of blowing of raining, extend transmission skin
The service life of band, it is to avoid shut down the adverse effect that adjustment belt causes to oil well production, reduces production cost, improves work effect
Rate.
The technical solution of the utility model is：A kind of driving belt take-up device includes pinch roller, and this device is additionally provided with and draws
Bar and fast pulley, submounts are provided with draw-bar seat, bearing and fixing wheel seat, and pull bar passes through and steel wire rope from draw-bar seat and bearing
Connect；Connecting rod and support are equipped with two, and one end of two connecting rods and support is arranged on the wheel shaft both sides of pinch roller, two connecting rods
The other end connected by connecting shaft, the other end of two supports is connected with bearing；The other end of steel wire rope is from the bottom of fast pulley
Face is bypassed and is connected with the connecting shaft of connecting rod；Equipped with spring between the adjusting nut of pull bar and draw-bar seat.
Compared with prior art, its significant using effect is this utility model：This device is arranged on the transmission of equipment
When above the driving belt of belt, especially oil pumper, when finding belt pine, rotate adjusting nut both stretchy pull bars, because
It is connected with steel wire rope for pull bar, steel wire rope drop-down compacting pinch roller is it becomes possible to tightening belt.When there is skidding in belt,
The single effect of the unilateral bearing in pinch roller can control and mitigate the skidding of belt.Spring plays elasticity and pulls pressure zone
The effect of wheel, not only easy to operate, and also mutually isostructural pinch roller will not damage driving belt.It is embodied in：
1st, Quick fastening belt, is not required to shut down, belt can be made to reach the adjustment standard of " four points one lines ".
2nd, drivewheel, follower are consistent with the trench structure of pinch roller three, can protect driving belt, with unilateral bearing
Pinch roller prevent rainy weather belt back skating, extend belt life.
3rd, the elasticity controllable visual of motor of oil extractor belt, is conducive to the precision management of belt.
Using this device on rod-pumped well, extend the service life of driving belt, it is to avoid shut down adjustment belt to oil
The adverse effect that well production causes, reduces production cost, improves work efficiency, have good using effect.This device
It is equally applicable to miscellaneous equipment, the driving belt of adjustment motor.
