Abstract
The utility model provides a slave tension device for the driving-belt of an oil pumping machine, which mainly solves the problems that the existing tension pulley is not slaved with the load change of the pumping unit, and the manufacturing cost of the unit set and the maintenance cost are high. The utility model is characterized in that the upper part of the bracket (1) is hinged with a slave shelf (4); the slave shelf (4) is fixedly connected to an acute angle shape by a cross bar (3) and a diagonal rod (4); the right end of the cross bar (3) is fixed with a clump weight (5), and the right end of the diagonal rod (4) is connected with a tension pulley (2) that is contacted with the loose edge of the belt. The slave tension device for the driving-belt of an oil pumping machine can be slaved with the load change of the pumping unit, and has the features of simple structure, low manufacturing cost of the unit set and low maintenance cost.
Description
Technical field:
The utility model relates to the used Idle wheel of oil recovery field, oil field pumping unit drivign belt, especially pumping unit drivign belt servo-actuated tension device.
Background technique:
In the work progress of oil field, along with continually developing of oil field, stratum energy consumes gradually, and some oil wells have been lost the blowing ability gradually.For the stable and high yields that guarantees crude oil, improve recovery rate, must be with the exploitation of mechanical oil recovery method to the oil well that these can not blowing.Pumping unit uses comparatively extensive in mechanical oil recovery, and the power of pumping unit, is pumped by the connecting rod drive by crank by belt transmission speed reducer by motor again, reaches the purpose of oil recovery.And 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.
The model utility content:
Can not change and servo-actuated, complex structure and separate unit cost and the high deficiency of maintenance cost along with pump load in order to overcome existing Idle wheel, the utility model provides a kind of pumping unit drivign belt servo-actuated tension device, this pumping unit drivign belt servo-actuated tension device can not only change and servo-actuated along with pump load, and has simple in structure, separate unit cost and the low characteristics of maintenance cost.
The technical solution of the utility model is: this pumping unit drivign belt servo-actuated tension device comprises Idle wheel and is fixed on the base upper bracket, the support upper articulation has arbitrary-movement articulator, arbitrary-movement articulator is fixedly connected into acute angle shape by cross bar and brace, cross bar right-hand member head is fixed with balancing weight, and brace right-hand member head is connected with the Idle wheel that touches mutually with the receding side of belt.
The beneficial effect that the utlity model has is: this pumping unit drivign belt servo-actuated tension device is owing to have arbitrary-movement articulator at the support upper articulation, and cross bar right-hand member head is fixed with balancing weight, and brace right-hand member head is connected with the Idle wheel that touches mutually with the receding side of belt.When the low load belt of pumping unit is relaxed, the Idle wheel of brace right-hand member head is fixed with under the balancing weight effect at cross bar right-hand member head, Idle wheel produces down pressure to the receding side of belt, make tension on belt, when pumping unit high capacity tension on belt, belt lifts the balancing weight of the cross bar right-hand member head Idle wheel by brace right-hand member head, thereby belt can constantly change and servo-actuated along with pump load, and simple in structure, separate unit cost and maintenance cost are low, and practical ranges is wide.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-support among the figure, 2-Idle wheel, 3-cross bar, 4-brace, 5-balancing weight.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this pumping unit drivign belt servo-actuated tension device comprises Idle wheel 2 and is fixed on base upper bracket 1, support 1 upper articulation has arbitrary-movement articulator 4, arbitrary-movement articulator 4 is fixedly connected into acute angle shape by cross bar 3 and brace 4, cross bar 3 right-hand member heads are fixed with balancing weight 5, and brace 4 right-hand member heads are connected with the Idle wheel 2 that touches mutually with the receding side of belt.When the low load belt of pumping unit is relaxed, the Idle wheel 2 of brace right-hand member head is fixed with under balancing weight 5 effects at cross bar 3 right-hand member heads, Idle wheel 2 produces down pressure to the receding side of belt, make tension on belt, when pumping unit high capacity tension on belt, belt lifts the balancing weight 5 of the cross bar right-hand member head Idle wheel 2 by brace right-hand member head, thereby belt can constantly change and servo-actuated along with pump load, and simple in structure, separate unit cost and maintenance cost are low, and practical ranges is wide.
