Abstract
The utility model relates to a belt tensioner, in particular to a self-operated belt tensioner used for tensioning a belt of an oil pumping machine for an oil well. The self-operated belt tensioner consists of a limit rod, lever beam hinge pin, a lever beam, a tensioning wheel hinge pin, a tensioning wheel, a counterweight and a supporting frame, and is characterized in that the counterweight is loosely sleeved at one end of the lever beam, the tensioning wheel is fixed at the other end of the lever beam through the tensioning wheel hinge pin, and is used for tightly pressing the belt of the oil pumping machine based on the lever principle, the lever beam is connected with the supporting frame through the lever beam hinge pin, and the limit rod is welded on the supporting frame. The self-operated belt tensioner has the beneficial effects that the belt cannot be damaged, the tightness of the belt can be adjusted automatically, the phenomena of elongating, loosening and slipping caused by long-time operation are avoided, the loss in transmission is avoided to the maximum degree, yield of the oil well is increased, loss of the belt is reduced, energy consumption is decreased, and labor intensity of workers is relieved.
Description
Technical field:
The utility model relates to a kind of belt tension mechanism, particularly a kind of self-powering type belt tightener that is used for the tensioning belt of oil pumping machine.
Background technique:
The pumping unit in oil field is by the belt pulley transmission of motor pulley through belt drive pumping unit, and is big because of loading, long operational time, and belt can slowly be elongated, fluffs, skid, and causes pumping unit idle running, has directly influenced oil well yield.Particularly viscous crude, ultra thick oil well are because the idle running of pumping unit, and the oil well pump of oil well can't in time be discharged crude oil, forms oil pipe and stops up, and the down-hole pumping unit is damaged, and causes serious economy loss.
The way that solves belt slack at present mainly is to adjust the degree of tightness of belt through the position of manual work adjustment motor, has increased working strength of workers.Because the particularity in oil field, the oil well distribution disperses, scope is wide, and oil well idle running can only lean on artificial tours of inspection just can learn; So adjust also untimelyly, adjustment lags behind, and transmission efficiency reduces; The belt rapid wear also can increase cost of production because of the belt slippage dry grinding produces high temperature scaling loss belt sometimes.
Summary of the invention:
In order to overcome the deficiency of existing technology, the utility model provides a kind of pumping unit self-powering type belt tightener, and this self-powering type belt tightener can be adjusted the elasticity of belt automatically, prevents that belt slippage from causing pumping unit idle running.
The utility model solves the technological scheme that its technical problem adopted: a kind of self-powering type belt tightener; Form by position-limited lever, lever beam bearing pin, lever beam, Idle wheel bearing pin, Idle wheel, counterweight and supporting frame; Its characteristic part is: the counterweight pine is enclosed within lever beam one end; Idle wheel is fixed on the lever beam the other end and utilizes lever principle to be pressed on the belt of oil pumping machine through the Idle wheel bearing pin, and the lever beam is connected with supporting frame through lever beam bearing pin, and position-limited lever is welded on the supporting frame.
The beneficial effect of the utility model is: do not damage belt; Can adjust the tightness of belt automatically, avoid avoiding the phenomenon that throws switch to greatest extent because of long operational time elongates, fluffs, the generation of skidding; Improved oil well output; Reduce the belt loss, and reduced energy consumption, also alleviated working strength of workers simultaneously.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1 position-limited lever, 2 lever beam bearing pins, 3 lever beams, 4 Idle wheel bearing pins, 5 Idle wheels, 6 belts, 7 counterweights, 8 supporting frames.
Embodiment:
In conjunction with accompanying drawing an embodiment is described:
Among the figure: cylindric counterweight 7 pines are enclosed within on the lever beam 3; And can move above that, with the adjustment arm of force, that the long-time running of the belt 6 on being fixed on pumping unit takes place is lax, when elongating; Counterweight 7 presses the lever bearing pin 2 of lever beam 3 on supporting frame 8 by gravity and rotates; Drive lever beam 3 the other ends and be installed in cylindric Idle wheel 5 on the Idle wheel bearing pin 4, be pressed on lax belt 6 outers, thereby adjusted the tightness of belt 6 along with belt 6 upwards produces displacement.The rotation amplitude of position-limited lever 1 control lever beam 3.
