Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly pumping unit is a kind of tension device of pumping unit drivign belt.
Background technique
At present, oil recovery field by using beam pumping unit recovers the oil.Beam pumping unit through belt pulley and belt transmission, drives the walking beam to-and-fro motion by motor.The degree of tightness of belt directly affects the efficient and the cost of pumping unit.And at present general the employing has fixed Idle wheel and the dynamic Idle wheel of follow-up-type, and fixed Idle wheel is with right labor strength when having reduced adjustment, but can not servo-actuated when pump load constantly changes, and tension effects is poor; The dynamic Idle wheel of follow-up-type can reduce adjustment work, and has kept the belt tension state preferably, but complex structure, separate unit cost and maintenance cost height, fault takes place frequently and cuts and can not handle on the spot, directly has influence on its energy-saving effect, and the practical application narrow limitation is bigger.Drivign belt need be regulated the belt degree of tightness, need become flexible four fang bolts and two motor jackscrews of motor of motor at least, and having adorned belt also needs the motor centering; guarantee four one lines; at least need two people to cooperate, waste time and energy, reach more than one hour dead time.
The model utility content
The purpose of this utility model is: a kind of roller-pressing type belt tensioner is provided, by the roller-pressing type belt tensioner under the situation of motionless motor fang bolt and jackscrew, utilize two pressure rollers to move, reach the purpose of regulating the belt degree of tightness in the direction of vertical and motor pulley and speed reducer pulley centerline.
The technical solution adopted in the utility model is: the roller-pressing type belt tensioner, mainly form by main tripod, secondary tripod, pressure roller, adjusting leading screw, pressing roller holder and major-minor link press span, it is characterized in that: main tripod and secondary tripod are that shaped steel (as angle steel, channel-section steel) is welded into, and main tripod is similar right-angled triangle to secondary tripod; The right angle side of main tripod is vertically fixed on the base of pumping unit, on the fixing main tripod of end welding of major-minor link press span, is welded with secondary tripod in the other end of major-minor link press span; The hypotenuse of main tripod and secondary tripod is parallel and perpendicular to the center line of motor pulley and speed reducer belt pulley.On the hypotenuse of secondary tripod, be fixed with an adjusting leading screw.Be connected with a pressing roller holder respectively at the two ends of regulating leading screw, the end welded steel pipe of pressing roller holder, there is internal thread the end of steel pipe, and the steel pipe internal thread is connected with the outside thread of regulating leading screw.Described pressing roller holder has the pressure roller dismounting groove.A pressure roller respectively is installed in the pressure roller dismounting groove of two pressing roller holders.Two pressure rollers are pressed in the outside of belt.
There is bearing at the pressure roller two ends.Bearings mounted purpose is to reduce the wearing and tearing of pressure roller to belt.The working width of pressure roller is greater than 20～50 millimeters of belt widths.
Take out pressure roller for convenience, the opening direction of the pressure roller dismounting groove on the described pressing roller holder is towards the speed reducer belt pulley.
Be processed with slide groove on main tripod and the secondary tripod, slide groove is used for fixing the adjusting leading screw.
The beneficial effects of the utility model: the utility model utilizes this roller-pressing type belt tensioner, can realize easily changing belt and tighten belt.Lift pressure roller when changing belt, earlier belt is inserted in the speed reducer belt pulley, pressure roller then closes, fix with regulator site, compress pressure roller and get final product, only regulate two distances between the pressure roller during tight belt and get final product, can also improve simultaneously the surface of contact of belt and belt pulley, improve transmission efficiency.
Description of drawings
Fig. 1 is the utility model roller-pressing type belt tensioner structural representation.
Among the figure: 1. main tripod, 2. secondary tripod, 3. pressure roller is 4. regulated leading screw, 5. pressing roller holder, 6. major-minor link press span, 7. motor pulley, 8. speed reducer belt pulley, 9. belt.
Embodiment
Consult Fig. 1.The roller-pressing type belt tensioner mainly is made up of main tripod 1, secondary tripod 2, pressure roller 3, adjusting leading screw 4, pressing roller holder 5 and major-minor link press span 6.
Main tripod 1 and secondary tripod 2 are that channel-section steel is welded into, and main tripod 1 is similar right-angled triangle to secondary tripod 2; The right angle side of main tripod 1 is vertically fixed on the base of pumping unit, and the end welding of major-minor link press span 6 is fixed on the main tripod 1, is welded with a secondary tripod 2 in the other end of major-minor link press span 6; Main tripod 1 is parallel with the hypotenuse of secondary tripod 2 and perpendicular to the center line of motor pulley 7 and speed reducer belt pulley 8.Be processed with slide groove on main tripod 1 and the secondary tripod 2.On the hypotenuse of secondary tripod 2, be fixed with an adjusting leading screw 4.Be connected with a pressing roller holder 5 respectively at the two ends of regulating leading screw 4, steel pipe of end welding of pressing roller holder 5, there is internal thread the end of steel pipe, and the internal thread of the end of steel pipe is consistent with the outside thread of regulating leading screw 4.Connecting the steel pipe internal thread is connected with the outside thread of regulating leading screw 4.Described pressing roller holder 5 has the pressure roller dismounting groove, and there is bearing at pressure roller 3 two ends.A pressure roller 3 respectively is installed in the pressure roller dismounting groove of two pressing roller holders 5.The opening direction of the pressure roller dismounting groove on the pressing roller holder 5 is towards the speed reducer belt pulley.The working width of pressure roller 3 is greater than 30 millimeters of belt widths.Two pressure rollers 3 are pressed in the outside of belt 9.
