Technical Field

[0001] This utility model relates to the technical field of belt motor auxiliary equipment, specifically to a belt tension adjustment device for an oil pumping unit motor. Background Technology

[0002] A beam pumping unit is a type of mechanical oil extraction equipment widely used in oil fields. Its core function is to convert the high-speed rotation of the ground drive motor into the low-frequency, long-stroke, high-load reciprocating linear motion of the plunger of the downhole pump using a belt, thereby lifting crude oil from the bottom of the well to the surface.

[0003] However, the existing installation methods for oil pumping units and drive motors have some drawbacks, such as:

[0004] When the belt between the pumping unit and the drive motor is too loose, the motor may run dry. The belt tension is difficult to adjust, requiring workers to disassemble and move the drive motor, which is a troublesome adjustment method.

[0005] Therefore, this utility model provides a belt tension adjustment device for an oil pumping unit motor to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a belt tension adjustment device for a pumping unit motor, so as to solve the problem of cumbersome adjustment method when adjusting the belt tension between the pumping unit and the drive motor.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0025] The following will refer to the attached reference. Figures 1 to 3 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0026] As attached Figure 1 - Appendix Figure 3 As shown, a pumping unit motor belt tension adjustment device includes a base bracket 1, a slide rail shaft 8, and a load-bearing fixing bracket 4.

[0027] Foundation bracket 1: See attached document Figure 1 and attached Figure 2 There are two anchor brackets 1. The two anchor brackets 1 are placed along the first direction y and symmetrically arranged side by side along the second direction x. The first direction y and the second direction x are perpendicular to each other. They are used to fix the device on a designated bracket or pier to install the device in a designated position. Both ends of the anchor bracket 1 are provided with horizontal adjustment mounting holes 2, which can adjust the installation position of the anchor bracket 1 and improve the assembly adaptability. A power source is fixedly connected to one of the anchor brackets 1.

[0028] Slide rail shaft 8: See appendix Figure 1 and attached Figure 2 There are two slide rail shafts 8, which are columnar. The two slide rail shafts 8 are placed along the second direction x and arranged side by side along the first direction y. Both ends of the slide rail shafts 8 are threaded with base slide rail fixing screws 10. The two base slide rail fixing screws 10 respectively abut against the two foot brackets 1, so as to fix the two slide rail shafts 8 between one end and the other end of the two foot brackets 1 respectively. The slide rail shafts 8 are arranged side by side with the power source.

[0029] Support bracket 4: See appendix Figure 1 and attached Figure 2There are two load-bearing fixing brackets 4, which are placed side by side along the first direction y and along the second direction x. Both ends of the upper side of the load-bearing fixing brackets 4 are provided with load-bearing lateral adjustment mounting holes 5. At the same time, the distance between the two load-bearing fixing brackets 4 can also be adjusted to accommodate the size of the motor, ensuring that motors with wider and narrower sizes can be installed on the load-bearing fixing brackets 4. Both ends of each load-bearing fixing bracket 4 are fixedly connected to an outer sliding sleeve 6 by screws. The outer sliding sleeve 6 is movably sleeved on the slide rail shaft 8, so that the load-bearing fixing bracket 4 slides on the slide rail shaft 8. The output end of the power source is fixedly connected to a connector 9. The other end of the connector 9 is fixed to one of the load-bearing fixing brackets 4. The power source drives the load-bearing fixing bracket 4 to slide through the connector 9. Notches 7 are provided on both sides of the load-bearing fixing brackets 4. The outer sliding sleeve 6 is fixed to the load-bearing fixing bracket 4 by screws. The notches 7 are aligned with the screws of the outer sliding sleeve 6, and the screws of the outer sliding sleeve 6 can be turned through the notches 7.

[0030] In this embodiment, refer to the appendix. Figure 3 The power source is a hydraulic power module 3. The output end of the hydraulic power module 3 is fixed on the bearing support bracket 4. The input end of the hydraulic power module 3 is electrically connected to the output end of the controller 11. The input end of the controller 11 is electrically connected to the output end of the distribution box 12.

[0031] The working principle of this device is as follows:

[0032] The distance between the two load-bearing fixed brackets 4 can be adjusted, and the load-bearing lateral adjustment mounting hole 5 is an extension hole, so that the distance between the two load-bearing fixed brackets 4 and the position of the load-bearing lateral adjustment mounting hole 5 can be adapted to the size of the drive motor. The drive motor is fixed on the two load-bearing fixed brackets 4. When the belt tension needs to be adjusted, the controller 11 controls the hydraulic power module 3 to push the load-bearing fixed brackets 4 to move, thereby driving the drive motor to move, controlling the distance between the drive motor and the pumping unit, and thus adjusting the belt tension.
