Problems solved by technology

[0009] (1) The advantage of using jackscrew adjustment is that the structure is simple and easy to use, but there are also irreplaceable shortcomings, the adjustment range is limited, and the labor intensity of employees is not fundamentally reduced
[0010] (2) The advantage of using the tensioner for adjustment is that the effect is obvious. However, due to the addition of a set of pressure wheels and a set of friction pairs, the energy consumption is increased. At the same time, because the tensioner is installed on the outside of the belt, winter It is easy to delaminate the belt during production and accelerate the damage of the belt
The disadvantage is that the actual wear degree of the belt cannot be judged in time, and early warning cannot be achieved. At the same time, manual inspection and monitoring are required, the efficiency is low, and automation cannot be realized.

Embodiment 1

[0033] An intelligent belt tension constant maintaining device includes a motor sliding base and a constant tension maintaining mechanism. The motor sliding base includes a motor base, a sliding rod, and a driving screw. The drive motor base makes reciprocating linear motion on the slide bar.

[0034] The constant tension maintaining mechanism includes a motor, a drive sprocket, a first sprocket, a drum, a gravity bucket, a second sprocket, and a third sprocket.

[0035] The drive sprocket is set on the output shaft of the motor, the first sprocket is connected to the drive sprocket through a chain, and the first sprocket and the second sprocket are coaxially arranged with the drum; the gravity bucket is hooked to the drum by winding the drive rope; The third sprocket is arranged at the end of the driving screw rod.

[0036] The third sprocket is connected to the second sprocket through a chain transmission; wherein, the first sprocket and the second sprocket are one-way spro...

Embodiment 2

[0038] An intelligent belt tension constant maintaining device also includes a torque amplification box, the torque amplification box is provided with an input sprocket and an output sprocket; the input sprocket is connected to the second sprocket; the output sprocket is connected to the second sprocket Three-sprocket drive connection.

[0039] There is a gear set inside the torque amplification box. Using the principle of leverage, the torque transmitted from the second sprocket to the input sprocket is amplified and transmitted to the output sprocket, so as to achieve the effect of producing a large tensioning torque with a small input torque.

Embodiment 3

[0041] An intelligent belt tension constant maintaining device also includes a motor controller and a position sensor, the position sensor is connected to the motor controller, and the position sensor includes an upper limit position sensor and a lower limit position sensor; the upper limit position sensor is arranged on the The upper limit position of the gravity barrel, the offline position sensor is set at the lower limit position of the gravity barrel.

[0042] The motor controller has functions such as motor start and stop, motor speed regulation, etc., and is used to control the motor.

[0043] The position sensor is a proximity position sensor, which is used to sense the position of the gravity barrel and transmit the switch signal to the motor controller at the same time.

Description

technical field [0001] The invention relates to a belt tension constant maintaining device for oil production equipment in an oil field, in particular to an intelligent belt tension constant maintaining device. Background technique [0002] The pumping unit is the main oil extraction equipment for oil extraction, and most of them are applied to the belt transmission mechanism, and the power is transmitted by the belt. In the production process, the performance of the belt will become lower and lower due to material aging, wear, and the influence of the ambient temperature, resulting in belt slippage and reduced transmission efficiency, thereby reducing the production efficiency of petroleum equipment. Therefore, after a period of production It is necessary to adjust the belt tension or replace the belt to maximize the transmission efficiency. Therefore, adjusting the tension of the belt or replacing the belt is a routine work of the oil production team and one of the import...
