Abstract
The utility model relates to a belt tightening device, in particular to the belt tightening device for a beam unit in an oil field, which comprises a pulley used for connecting with a speed changing box and connected with a motor through a belt. The device is characterized in that a connecting roller wheel is arranged on the belt tightly, one end of the roller wheel is provided with a connecting rod, and a torsional spring is fixedly arranged on a head of the connecting rod. The belt tightening device completely avoids phenomena that the belt is lengthened and loosened caused by changes of weather and runtime extension, and the belt slips during transmission, prolongs service life of the belt, and reduces production loss caused by shutting down a machine to change the belts.
Description
(1) technical field
The utility model relates to a kind of belt stretcher, particularly a kind of oil-field oil pumper belt tightener.
(2) background technique
Beam pumping unit is big because of loading, and open-air operating mode is abominable, behind the installation belt, fluffs, produces skidding because of weather temperature variation, belt and belt pulley friction driving V band use a period of time just to be elongated, and causes belt to damage; It is even more serious to run into the skidding of sleety weather V band, blows belt if handle untimely meeting, directly influences oil well yield.
In case belt slippage idle running, belt damages, and stops the well accident, and the oil well pump of oil well can't in time be extracted crude oil out, causes oil pipe to stop up, and damages pumping unit, causes enormous economic loss; Simultaneously, replacing belt program is loaded down with trivial details, not easy to operate.
(3) summary of the invention
The utility model provides a kind of and has eliminated skidding, alleviated the oil-field oil pumper belt tightener of working strength in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of oil-field oil pumper belt tightener comprises the belt pulley that connects gearbox, and belt pulley is connected with motor by belt, it is characterized in that: closely press on the described belt to be provided with the connection running roller, running roller one end is provided with connecting rod, and torsion spring is fixed and be equipped with to link end.
The utility model utilizes torsion spring power or the gravity of self, closely contacts and compresses with the belt outer, forces belt tension, makes belt of oil pumping machine be in constant, the best running state that compresses all the time, thoroughly eliminates the belt transmission skidding.
More excellent scheme of the present utility model is:
For effectively utilizing surrounding environment, make things convenient for the fixing of connecting rod, described link end is fixed on gearbox one side.
The utility model has thoroughly been eliminated belt and has been elongated, fluffs because of factors such as changes of weather, prolongations working time; avoided the belt transmission skidding; prolonged belt working life; more reduced because of changing belt and shut down the production loss that causes; alleviated the labor intensity of changing belt; improve the transmission efficiency of belt greatly, improved the system effectiveness of pumping unit.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1 gearbox, 2 belt pulleys, 3 belts, 4 motors, 5 running rollers, 6 connecting rods, 7 torsion springs.
(5) embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.This embodiment comprises the belt pulley 2 that connects gearbox 1, and belt pulley 2 is connected with motor 4 by belt 3, closely presses to be provided with on the described belt 3 to connect running roller 5, and running roller 5 one ends are provided with connecting rod 6, and torsion spring 7 is fixed and be equipped with in connecting rod 6 terminations; Described connecting rod 6 terminations are fixed on gearbox 1 one sides.
The utility model utilizes torsion spring 7 or the gravity of self, makes running roller 5 closely contact and compress with belt 3 outers, and after the appropriateness debugging, the running of can starting shooting has effectively been avoided belt 3 transmission slips, phenomenon fluffs; Simultaneously, under the suitable elasticity of belt 3, support the upper roll wheel support, do not need the mobile motor 4 of requiring great effort again, just can change belt faster, reduced the workload of on-the-spot installation, adjustment belt.
The belt 3 of pumping unit turns round under reasonable tension, technology is adjusted automatically, eliminated suffered (tension) positive pulling force or (loose excessively) the negative pulling force of belt, and the positive pulling force that causes of working conditions change, negative pulling force alternate destroy, and in the working life of effectively having improved belt, running roller 5 is in the belt back running of rolling, without any destruction, the cornerite that rear motor 4 and belt 3 are installed increases, and the transmission efficiency of belt 3 improves greatly, the also corresponding raising of the system effectiveness of pumping unit.
Claims (2)
1. oil-field oil pumper belt tightener, comprise the belt pulley (2) that connects gearbox (1), belt pulley (2) is connected with motor (4) by belt (3), it is characterized in that: described belt (3) is gone up closely to press to be provided with and is connected running roller (5), running roller (5) one ends are provided with connecting rod (6), and torsion spring (7) is fixed and be equipped with in connecting rod (6) termination.
2. oil-field oil pumper belt tightener according to claim 1 is characterized in that: described connecting rod (6) termination is fixed on gearbox (1) one side.
