Description
Technical Field
[0001] This utility model relates to the field of oilfield oil production engineering technology, and in particular to a donkey head alignment detection device for an oil pumping unit. Background Technology
[0002] Pumping units, as a common type of rod-pumped oil production equipment, are widely used in oil fields. The pumping head, as one of its indispensable key components, plays a crucial role in the operation of the pumping unit. Located at the front end of the walking beam of the pumping unit, the pumping head is connected to the polished rod via a suspension cable. Under the combined action of the crank, connecting rod, and walking beam, it reciprocates up and down around the support bearing, thereby driving the pump plunger downhole to move up and down, which is key to realizing oil extraction.
[0003] During normal operation of an oil pumping unit, the suspension cable connected to the pumping head should always be positioned directly above the wellhead to ensure the polished rod can move vertically up and down. However, in practice, installation errors, wear and tear from long-term use, or uneven load distribution can easily lead to misalignment of the pumping head. This not only negatively impacts the pumping unit's efficiency but also significantly increases safety risks. The current technology requires operators to frequently climb to unload the pumping head and adjust its position, resulting in low efficiency and increased operational risks. Summary of the Invention
[0004] (a) Technical problems to be solved This invention provides a detection device for the alignment of the pumping unit's donkey head, which overcomes the problem in the existing technology that when the donkey head of the pumping unit is misaligned, operators need to climb up multiple times to unload and adjust its position, resulting in low work efficiency and increased operational risks.
[0005] (II) Technical Solution To achieve the above objectives, this utility model provides a donkey head alignment detection device for an oil pumping unit, comprising: a fixed plate, a projection pen, a projection adjustment plate, a locking bolt, a base, a slide rail, a front pressure plate, a rear pressure plate, and a tightening bolt; The base is made of a magnetic metal material. The base includes a crossbeam and two rectangular support structures. The crossbeam is a rear pressure plate. The two rectangular supports are evenly distributed on the same side of the rear pressure plate. Tightening the bolts fixes the position of the base by connecting the front pressure plate and the rear pressure plate. The rear pressure plate has three semi-circular grooves on the side away from the base, and the plane between the grooves is a platform. The platform part of the rear pressure plate has threaded holes. The front pressure plate has three semi-circular grooves on one side, which are corresponding to the platform of the rear pressure plate. The other side of the front pressure plate has a protruding rectangular structure. The rectangular structure has threaded through holes. The threaded through holes and threaded holes are matched. The tightening bolt connects the front pressure plate and the rear pressure plate through the threaded holes and through holes to fix the position of the base. When the tightening bolt is tightened, the platform parts of the front pressure plate and the rear pressure plate fit tightly together, and the semi-circular groove parts corresponding to them form three round holes in total. The fixing plate is made of magnetic material and is magnetically connected to the base. The fixing plate has a rotating shaft buckle on one side and the projection adjustment plate has a rotating shaft on one side. The projection adjustment plate and the fixing plate are connected by the rotating shaft structure. Both the fixing plate and the projection adjustment plate have threaded holes that match the locking bolts. The two threaded holes are located on the same vertical line. The upper surface of the projection adjustment plate has two grooves. The projection pen is installed in the grooves and connected to the projection adjustment plate. The slide is a rectangular structure with an elliptical hole in the center. The slide has two locking bolts, namely a first locking bolt and a second locking bolt. The first locking bolt passes through the elliptical hole of the slide and connects to the projection adjustment plate to fix the raised height of the adjustment plate. The second locking bolt passes through the elliptical hole and connects the slide and the fixing plate.
[0006] Preferably, the projection adjustment plate rotates via a rotating shaft structure to adjust the vertical height between itself and the fixed plate, thereby moving the first locking bolt and the slide rail.
[0007] Preferably, when the projection adjustment plate adjusts its height, it moves the projection pen to change its height.
[0008] Preferably, the projection pen is a laser pen, and the projection pen is equipped with a switch. When the switch is turned on, the projection pen emits a straight laser beam.
[0009] (III) Beneficial Effects This invention provides a device for aligning the pumping unit's pumping head. When the pumping unit's pumping head is misaligned, the device connects the front and rear pressure plates by tightening bolts to fix the position of the base. A projection adjustment plate connected to the base is fixed by a fixing plate, and a projection pen is connected to it. The height of the fixing plate is adjusted, and the position is fixed by locking bolts. The device uses the laser beam emitted by the projection pen as a reference to align the pumping unit's pumping head, thus completing the adjustment operation in one step. This avoids the need for multiple unloading operations at height, improving work efficiency and operational safety. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0015] In the description of this utility model, it is necessary to understand that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "top", and "bottom" are all based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of this utility model and simplify the description, and is not intended to indicate or imply that the indicated component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0016] like Figure 1-3 As shown, the present invention provides a donkey head alignment detection device for an oil pumping unit, comprising a fixing plate 1, a projection pen 2, a projection adjustment plate 3, a locking bolt 4, a base 5, a slide rail 6, a front pressure plate 7, a rear pressure plate 8, and a tightening bolt 9.
[0017] like Figure 2 As shown, the base 5 is made of magnetic metal material. The base 5 includes a crossbeam and two rectangular support structures. The crossbeam is the rear pressure plate 8. The two rectangular supports are evenly distributed on the same side of the rear pressure plate 8. The front pressure plate 7 and the rear pressure plate 8 are connected by tightening bolts 9 to fix the position of the base 5 and make the base 5 stably fixed above the pumping unit's suspension clamp.
[0018] like Figure 3As shown, the rear pressure plate 8 has three semi-circular grooves on one side. Centered on the polished rod, three semi-circular grooves with a diameter of 28mm and a spacing of 12mm are provided. The plane between the grooves is a platform, and the platform part has threaded holes. The front pressure plate 7 has three semi-circular grooves on the side near the rear pressure plate 8, corresponding to the rear pressure plate 8. The other side has a protruding rectangular structure. The rectangular structure part has threaded through holes corresponding to the threaded holes of the rear pressure plate 8. The tightening bolt 9 passes through the threaded through holes of the front pressure plate 7 and the threaded holes of the rear pressure plate 8, and after tightening, it fixes the position of the base 5. When the tightening bolt 9 is tightened, the platform parts of the front pressure plate 7 and the rear pressure plate 8 fit tightly together. The semi-circular grooves on both sides form three round holes. The middle round hole is the polished rod placement hole, and the round holes on both sides are for placing the two braids of the pumping unit.
[0019] like Figure 1-2 As shown, the fixing plate 1 is made of magnetic material and is magnetically fixed to the base 5. A rotating shaft buckle is provided on one side of the fixing plate 1. A rotating shaft is provided on one side of the projection adjustment plate 3, and the projection adjustment plate 3 is connected to the fixing plate 1 via the rotating shaft structure. The projection adjustment plate 3 can be lifted via the rotating shaft structure to form a certain angle with the fixing plate 1. A threaded hole is provided on one side of the fixing plate 1, and the projection adjustment plate 3 has a threaded hole on the same side and corresponding to the fixing plate 1. These two threaded holes are matched with locking bolts 4.
[0020] like Figure 3 As shown, the projection adjustment plate 3 has two grooves on the side away from the rotating shaft. With the light rod as the center point, the distance between the two grooves is 23.5mm. These grooves are used to install and fix the projection pen 2. The projection pen 2 is equipped with a switch. When the projection pen 2 is turned on, it can emit a straight laser beam.
[0021] like Figure 1-2 As shown, the slide 6 has a rectangular structure with an elliptical elongated hole in the center. The slide 6 has two locking bolts 4, namely a first locking bolt 41 and a second locking bolt 42. The first locking bolt 41 passes through the elliptical elongated hole of the slide 6 and is fixedly connected to the projection adjustment plate 3. The second locking bolt 42 passes through the elliptical elongated hole of the slide 6 and is fixedly connected to the fixing plate 1. The second locking bolt 42 is located below the first locking bolt 41.
[0022] When the projection adjustment plate 3 is lifted by the rotating shaft structure, it drives the projection pen 2, which is fixedly installed in the groove of the projection adjustment plate 3, to move. The position of the projection adjustment plate is fixed by the first locking bolt 41, so that the projection pen 2 is placed at the required height. At the same time, it prevents the projection adjustment plate 3 from slipping due to its own weight, which would cause the laser emitted by the projection pen 2 to be unstable, thereby improving the work efficiency of the operator.
[0023] It is important to note that in practical work, it is best to choose a laser pointer that emits colored laser light as the projection pen 2 so that the emitted laser beam can be observed during the day.
[0024] It should be noted that the 8-type oil pumping unit was selected as the test machine for this embodiment. The diameter and spacing of the semi-circular grooves and the spacing of the laser pointer mounting grooves set in the above content can be adjusted accordingly according to the work requirements.
[0025] The following is a detailed description of the actual working scenario of a donkey head alignment detection device for an oil pumping unit.
[0026] In practical work, the front pressure plate 7 and the rear pressure plate 8 are connected by tightening bolt 9 to fix the position of the base 5. The fixing plate 1 is magnetically connected to the base 5. The projection adjustment plate 3 is connected to the fixing plate 1 through a rotating shaft. The projection adjustment plate 3 is provided with a groove to fix the projection pen 2. The projection adjustment plate 3 can be fixed to a fixed height by the locking bolt 4 set in the slide 6. The projection pen 2 is turned on and the laser beam it emits can be used to conveniently observe the adjustment of the donkey head alignment. This allows the adjustment operation to be completed in one go, avoiding the need to climb up and unload the donkey head multiple times, improving work efficiency and reducing operational risks.
