[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] Please combine them together Figures 1 to 4 The experimental apparatus for the oil pumping unit provided by this utility model will now be described.

[0034] The oil pumping unit experimental apparatus includes: a frame 1, a drive assembly 2, a crank 3, a connecting rod 4, a walking beam 5, and a donkey head 6. The drive assembly 2 is mounted on the frame 1 and is connected to the crank 3 for driving its rotation. The crank 3 is rotatably connected to the connecting rod 4, which is rotatably connected to and detachable from the walking beam 5. The walking beam 5 is rotatably connected to and detachable from the frame 1, and is connected to the donkey head 6. Specifically, the drive assembly 2 is fixed to the frame 1, and the walking beam 5 and donkey head 6 are fixed together with screws.

[0035] Understandably, the drive assembly 2 of the oil pumping unit experimental device is installed on the frame 1. The drive assembly 2 is connected to the crank 3 and is used to drive the crank 3 to rotate. The crank 3 is rotatably connected to the connecting rod 4. The connecting rod 4 is rotatably connected to the walking beam 5 and is detachable from the walking beam 5. The walking beam 5 is rotatably connected to the frame 1 and is detachable from the frame 1. The walking beam 5 is connected to the donkey head 6. Because the connecting rod 4 and the walking beam 5 are detachable, and the frame 1 and the walking beam 5 are detachable, the walking beam 5 can change position, thereby allowing the donkey head 6 to change its driving form, thereby improving adaptability and enhancing students' practical cognition and innovation ability.

[0036] Furthermore, since the connecting rod 4 and the walking beam 5 are detachable, as are the frame 1 and the walking beam 5, students can adjust the position of the walking beam 5 as needed, thereby improving the applicability of this oil pumping unit experimental device.

[0037] It should be noted that the drive assembly 2 can drive the crank 3 to rotate, the crank 3 in turn drives the connecting rod 4 to reciprocate, and the connecting rod 4 in turn drives the walking beam 5 and the donkey head 6 to reciprocate. The special shape of the donkey head 6, with its arc-shaped centering, can achieve alignment with the load center when simulating oil pumping. The donkey head 6 is connected to the load through a rope assembly.

[0038] In this embodiment, the installation method of the walking beam 5 has multiple implementation methods:

[0039] In one embodiment, the oil pumping experimental apparatus further includes a first connecting frame 51, a first fastener 52, a second connecting frame 53, and a second fastener 54. The first fastener 52 passes through the first connecting frame 51 and is connected to one end of the walking beam 5. The second fastener 54 passes through the second connecting frame 53 and is connected to the middle of the walking beam 5. The connecting rod 4 is rotatably connected to the first connecting frame 51, and the frame 1 is rotatably connected to the second connecting frame 53. Specifically, both the first fastener 52 and the second fastener 54 are bolts. The first fastener 52 passes through the first connecting frame 51 and is threadedly connected to one end of the walking beam 5, making the walking beam 5 detachable from the connecting rod 4. The second fastener 54 passes through the second connecting frame 53 and is threadedly connected to the middle of the walking beam 5, making the walking beam 5 detachable from the frame 1. This allows the donkey head 6 to be positioned behind the crank 3, achieving a rear-drive configuration.

[0040] In another embodiment, the oil extraction experimental device further includes a first connecting frame 51, a first fastener 52, a second connecting frame 53, and a second fastener 54. The first fastener 52 passes through the first connecting frame 51 and is connected to the middle of the walking beam 5. The second fastener 54 passes through the second connecting frame 53 and is connected to one end of the walking beam 5. The connecting rod 4 is rotatably connected to the first connecting frame 51, and the frame 1 is rotatably connected to the second connecting frame 53. Specifically, both the first fastener 52 and the second fastener 54 are bolts. The first fastener 52 passes through the first connecting frame 51 and is threadedly connected to the middle of the walking beam 5, making the walking beam 5 detachable from the connecting rod 4. The second fastener 54 passes through the second connecting frame 53 and is threadedly connected to one end of the walking beam 5, making the walking beam 5 detachable from the frame 1. This allows the donkey head 6 to be positioned in front of the crank 3, achieving a front-drive configuration.

[0041] Furthermore, the oil extraction experimental apparatus also includes a first bearing 55 and a second bearing 56. The connecting rod 4 is rotatably connected to the first connecting frame 51 via the first bearing 55, and the frame 1 is rotatably connected to the second connecting frame 53 via the second bearing 56. This allows the connecting rod 4 to be rotatably connected to the walking beam 5, and the frame 1 to be rotatably connected to the walking beam 5. In addition, the inclusion of the first bearing 55 and the second bearing 56 reduces friction, resulting in smoother rotation of the connecting rod 4 and the walking beam 5, and smoother rotation of the frame 1 and the walking beam 5.

[0042] In one embodiment, such as Figure 1 The oil extraction experimental apparatus further includes a third bearing 7, through which the crank 3 is rotatably connected to the connecting rod 4. Thus, by providing the third bearing 7, the crank 3 and the connecting rod 4 can rotate relative to each other. Furthermore, this reduces the friction between the connecting rod 4 and the crank 3, resulting in smoother rotation of both.

[0043] In one embodiment, such as Figures 1 to 3 As shown, the drive assembly 2 includes a drive motor 21, a belt drive module 22, and a reducer module 23. The drive motor 21 is mounted on the frame 1 and is connected to the belt drive module 22. The belt drive module 22 is connected to the reducer module 23, and the reducer module 23 is connected to the crank 3. Specifically, the reducer module 23 is fixedly connected to one end of the crank 3. The drive motor 21 drives the belt drive module 22 to rotate the reducer module 23, which in turn drives the crank 3 to rotate. The crank 3 then drives the connecting rod 4, the walking beam 5, and the head 6 to reciprocate.

[0044] In this embodiment, the belt drive module 22 includes a small pulley 221, a large pulley 222, and a synchronous belt 223. The drive motor 21 is connected to the small pulley 221, which is rotatably connected to the frame 1. The large pulley 222 is rotatably connected to the frame 1 and connected to the output shaft of the reducer module 23. The synchronous belt 223 surrounds the small pulley 221 and the large pulley 222. Specifically, the drive motor 21 is fixedly connected to the small pulley 221, and the large pulley 222 is fixedly connected to the output shaft of the reducer module 23. The drive motor 21 drives the small pulley 221 to rotate, which in turn drives the synchronous belt 223 to move. The synchronous belt 223 then drives the large pulley 222 to rotate, which in turn drives the reducer module 23 to rotate, and the reducer module 23 then drives the crank 3 to rotate. The synchronous belt 223 transmits power to the small pulley 221 and the large pulley 222 through friction. In case of overload, slippage can protect the motor. The reducer module 23 can reduce the speed and increase the torque, thereby increasing the torque of the crank 3, which in turn increases the torque of the donkey head 6.

[0045] Furthermore, the belt drive module 22 also includes a tensioner 224, which is mounted on the frame 1 and used to tension the synchronous belt 223. By setting the tensioner 224, when the synchronous belt 223 becomes loose from the small pulley 221 and the large pulley 222, the tensioner 224 can tension the synchronous belt 223 to ensure the friction between the synchronous belt 223 and the small pulley 221 and the large pulley 222.

[0046] In one embodiment, such as Figure 3As shown, the oil pumping unit experimental apparatus also includes a first sensor, which is mounted on the frame 1 and used to sense the output shaft torque of the reducer. Specifically, the first sensor can be a torque sensor (not shown in the figure) to measure the torque of the reducer output shaft.

[0047] In this embodiment, the pumping unit experimental apparatus further includes a second sensor, which is mounted on the frame 1 and used to sense the rotational speed of the reducer's output shaft. Specifically, the second sensor is an angle sensor (not shown in the figure) capable of measuring the rotational speed of the reducer's output shaft.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
