[0002] A pumping unit is a device used to extract oil or natural gas from underground wells. It typically consists of several key components, including a pump, motor, transmission system, and control system. The pumping unit belt's primary function is to transmit power from the motor to the pump shaft, driving the unit. Specifically, when the motor starts, power is transmitted via the belt to the pump shaft, causing it to rotate and, in turn, drive the unit to pump oil. Therefore, the pumping unit belt plays a crucial role in the pumping process. However, existing pumping unit belts, after operating for a certain period of time, are exposed to sunlight or crack, causing them to deform, stretch, or become loose, resulting in the unit's inability to operate normally. Traditional belt adjustment structures are irrational, resulting in poor adjustment effectiveness and difficulty in operation.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0017] Pumping unit belt tension adjustment device, such as Figure 1 As shown, it includes a base plate 1, and guide components 3 are respectively provided on both sides of the base plate 1. A supporting component 2 is slidably connected between the two guide components 3. A fixing component 9 is provided between the supporting component 2 and the base plate 1. Tension adjustment components 4 are respectively provided on both sides of the fixing component 9. The two ends of the tension adjustment component 4 are respectively fixed to the supporting component 2 and the base plate 1.

[0018] The supporting assembly 2 comprises a U-shaped frame 202, with two inner walls formed with axial holes. A steering column wheel 201 is positioned between the two inner walls. The ends of the steering column wheel 201 fit within the two inner walls of the U-shaped frame 202. The guiding assembly 3 comprises a stopper plate 301, one end of which is fixedly attached to the surface of the base plate 1. A stopper slot 302 is defined on the end of the stopper plate 301 facing away from the base plate 1. The stopper slot 302 cooperates with the supporting assembly 2. The ends of the U-shaped frame 202 fit between the stopper slots 302, and the ends of the U-shaped frame 202 are slidably connected to the stopper plates 301.

[0019] The tension adjustment assembly 4 includes a telescopic rod 401, which is arranged between the two limit plates 301. One end of the telescopic rod 401 is fixed to the plate surface of the base plate 1, and the other end is fixed to the side of the U-shaped frame 202 away from the steering column wheel 201; a spring 402 is mounted on the telescopic rod 401, and the two ends of the spring 402 are respectively in contact with the plate surface of the base plate 1 and the U-shaped frame 202.

[0020] The fixing assembly 9 includes a positioning ring 8, which is fixed to the side of the U-shaped frame 202 away from the steering column wheel 201. The positioning ring 8 is arranged between the two telescopic rods 401. The positioning ring 8 is equipped with a movable hook 7. The end of the movable hook 7 away from the positioning ring 8 is fixed to a rope 6. The end of the rope 6 away from the positioning ring 8 is fixed to a fixing block 5. The fixing block 5 is fixed to the surface of the base plate 1. The base plate 1 is a rectangular plate with a plurality of through holes.

[0021] The working principle of the present invention is as follows: when replacing the oil pumping unit belt, the steering column wheel 201 is pressed to compress the spring 402, and the spring 402 will shrink at this time. Then, the movable hook 7 can be hung on the positioning ring 8 on the U-shaped frame 202, and then the U-shaped frame 202 can be limited under the connection of the positioning ring 8 and the rope 6. At this time, the steering column wheel 201 will be away from the belt, which is convenient for the staff to replace the belt. When the belt is replaced, the movable hook 7 is removed from the positioning ring 8, so that the U-shaped frame 202 can be driven by the elastic force of the spring 402 to make the steering column wheel 201 tighten the oil pumping unit belt.

[0022] The adjusting device is fixed at a specified position by the base plate 1, and the base plate 1 provides an installation basis for the two guide components 3 and the two tension adjustment components 4. Then, the two tension adjustment components 4 can provide elastic support to the top holding component 2, so that the top holding component 2 can provide elastic force to the oil pumping unit belt, and thus the oil pumping unit belt can always maintain the required relaxed state, so as to improve the smooth operation of the oil pumping unit belt. The two guide components 3 can provide smooth guidance for the top holding component 2, so as to prevent the top holding component 2 from tilting when supporting the belt, further ensuring the stability of the top holding component 2 supporting the belt.

[0023] This utility model reconstructs and innovates the automatic adjustment structure and installation component setting method, and designs a new, simple and practical adjustment device to further meet the on-site needs of oilfield pumping unit belt tension adjustment, improve production efficiency, and continuously improve the level of oilfield ground construction. This utility model meets the actual needs of oilfields and solves the problem of belt loosening caused by long-term operation during the operation of the pumping unit. It can be installed and used on pumping units of different models and produced by different manufacturers currently used in oilfields, improving the working efficiency of the pumping units. The installation of this utility model provides a new method and new ideas for oil and gas pumping unit equipment and even related industries.
