Description

Technical Field

[0001] This invention relates to the field of oil pumping units, specifically to a device and method for checking and adjusting the levelness of an oil pumping unit base. Background Technology

[0002] An oil pumping unit is a mechanical device used for oil extraction, and it is the most important lifting device in a rod-operated pumping system. Typically, the lower half of a concrete foundation is deeply buried in the ground, while the upper surface of the foundation supports the pumping unit base. Multiple sets of shims are used to adjust the level of the pumping unit base in various dimensions, including the horizontal and vertical directions, to prevent the pumping unit from tipping over during operation. Due to alternating loads during operation and the impact of rain, snow, and ice on the ground foundation, the levelness of the pumping unit base can change. Regular inspections and adjustments based on the inspection results are necessary. Currently, adjusting the pumping unit base requires the use of heavy machinery, which is not only wasteful of manpower and resources but also highly prone to accidents—a drawback of existing technology. Summary of the Invention

[0003] To overcome the shortcomings of existing pumping unit base adjustments which require the use of large machinery and waste manpower and resources, this invention provides a pumping unit base leveling inspection and adjustment device and method. This pumping unit base leveling inspection and adjustment device can detect and adjust the levelness of the pumping unit base without the need for large mechanisms, and has a simple and compact structure that is easy to operate.

[0004] The technical solution of the present invention is: a pumping unit base leveling inspection and adjustment device, including a pumping unit base, a level ruler is respectively set on the four sides above the pumping unit base, a leveling adjustment device is connected to the pumping unit base, the leveling adjustment device includes a crossbeam, two hooks are connected to the lower end of the crossbeam, the lower ends of the two hooks are respectively connected to both sides of the pumping unit base, and jacks are respectively connected to the lower ends of the crossbeam.

[0005] Furthermore, the hook includes a crossbeam hanging ring, which is fitted onto the crossbeam. The lower end of the crossbeam hanging ring is connected to a shovel hook via a connecting chain, and the shovel hook is hooked onto the base of the oil pumping unit.

[0006] Furthermore, the jack is supported on a cement foundation by a jack support, and a manual oil pump is connected to the jack.

[0007] Furthermore, the shovel hook includes a vertical plate, the upper end of which is bolted to a connecting chain, and the lower end of which is connected to a horizontally oriented flat plate.

[0008] Furthermore, there are four level rulers, which are respectively set around the upper perimeter of the pumping unit base, and the direction of each level ruler is consistent with the direction of the corresponding pumping unit base frame.

[0009] A method for adjusting the levelness of a pumping unit base, using the aforementioned pumping unit base levelness inspection and adjustment device, includes: S1. Determine whether the pumping unit base needs adjustment and the direction of adjustment based on the display of the four spirit levels; S2. Support the two crossbeams above the pumping unit base with jacks; connect the two ends of the connecting chain to the crossbeam ring and the shovel hook respectively; put the crossbeam ring on the crossbeam and hook the shovel hook onto the pumping unit base; S3. Loosen the anchor bolts of the pumping unit base and remove the shims; adjust the extension of the four jacks respectively so that the four spirit levels all show level. S4. Install the leveling pads, tighten the anchor bolts, retract the jack, and check again whether the four spirit levels are level. If they are not level, repeat step S3. If the spirit level shows that it is level, the adjustment is complete.

[0010] Furthermore, in step S2, the jack support is placed on the cement foundation, the jack is placed on the jack support, the crossbeam spans the pumping unit base, and there is a jack at the bottom of each end of the crossbeam.

[0011] Furthermore, in step S2, the length of the connecting chain is selected based on the height of the crossbeam.

[0012] Furthermore, in step S2, the height of the jack support is selected based on the height of the pumping unit base.

[0013] The present invention has the following beneficial effects: Due to the adoption of the above-mentioned solution, the pumping unit base leveling and adjustment device can smoothly complete the leveling measurement of various positions of the pumping unit base, and simultaneously adjust the leveling of the pumping unit base according to the measurement results, ensuring smooth production. Moreover, it is easy to operate. The device has a compact structure, is flexible in application, and adapts to various pumping unit models, avoiding the problem of previously requiring large hoisting equipment for adjustments. Adjustment can be completed by two people, resulting in high efficiency and low cost. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are intended only to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the components referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Depend on Figures 1 to 4 As shown, a leveling and adjusting device for a pumping unit base includes a pumping unit base 1. Four level gauges 2 are installed around the top of the pumping unit base 1, one on each side. Each level gauge 2 is fixed along the length of the side of the pumping unit base, meaning the direction of the level gauges on the two longer sides is perpendicular to the direction of the level gauges on the two shorter sides. This allows for accurate detection of the levelness of the pumping unit base 1 based on the readings of the four level gauges 2. A leveling adjustment device 3 is connected to the pumping unit base 1. Typically, two leveling adjustment devices are used in conjunction, one at each end of the pumping unit base 1. These devices can be installed as needed and removed after leveling. Several shims 5 of varying thicknesses are provided at the bottom of the pumping unit base 1. The levelness of the pumping unit base 1 is adjusted by varying the thickness of the shims 5. After leveling, the pumping unit base 1 is fixed to a concrete foundation 6 using anchor bolts 4.

[0019] The leveling adjustment device 3 includes a crossbeam 305, which spans the pumping unit base 1 when adjusting the level. To shorten the length of the crossbeam 305 and make adjustment easier, [the following is omitted as it is not part of the technical description]. Figure 1As shown, the crossbeam 305 is parallel to the short side of the pumping unit base 1 and spans the long side of the base. Two hooks 304 are connected to the lower end of the crossbeam 305, with the lower ends of the hooks 304 connected to both sides of the pumping unit base 1. Jacks 303 are connected to the lower ends of both ends of the crossbeam 305, and jack supports 302 are provided at the bottom of each jack 303. The jacks 303 are supported on the concrete foundation 6 via the jack supports 302, and a manual oil pump 301 is connected to each jack 303. Since there are two leveling devices 3, each with a jack 303 at both ends of its crossbeam 305, this means there is one jack 303 at each of the four corners of the pumping unit base 1. By adjusting the lifting height of different jacks 303, the levelness of the pumping unit base 1 can be adjusted. Multiple jack supports 302 of different heights can be provided to accommodate pumping unit bases 1 of varying heights.

[0020] The hook 304 includes a crossbeam hanging ring 3041, see Figure 3 The cross-section of the beam hanging ring 3041 matches that of the beam 305, allowing it to be fitted onto the beam 305 and easily removed. The lower end of the beam hanging ring 3041 is connected to a shovel hook 3043 via a connecting chain 3042, and the shovel hook 3043 hooks onto the pumping unit base 1. See [link / description missing]. Figure 2 The connecting chain 3042 is bolted to the crossbeam hanging ring 3041, and similarly, the connecting chain 3042 is bolted to the hook 3043; both are detachable. Since different pumping unit bases have different heights, multiple connecting chains 3042 of different lengths can be prepared in advance and selected as needed. This significantly reduces the extension of the jack 303, making the jack support more stable and reducing the time required for leveling.

[0021] To facilitate the hook 3043 engaging with the pumping unit base 1, the hook 3043 can adopt the following structure: it includes a vertical plate, the upper end of which is bolted to the connecting chain 3042, and the lower end of which is connected to a horizontal plate. Since the pumping unit base 1 is mostly made of channel steel or I-beams, during adjustment, the plate of the hook 3043 can be inserted under the pumping unit base 1, and lifted by the jack 303, tightening the connecting chain 3042, thereby raising the pumping unit base 1.

[0022] The pumping unit base leveling and adjustment device can smoothly measure the levelness of various positions on the pumping unit base, and adjust the levelness of the base based on the measurement results to ensure smooth production. It is also easy to operate. The device is compact, flexible in application, and adaptable to various pumping unit models. It avoids the problem of previously requiring large hoisting equipment for adjustments; two people can complete the adjustment, resulting in high efficiency and low cost.

[0023] The present invention also provides a method for adjusting the levelness of a pumping unit base, using the aforementioned pumping unit base levelness inspection and adjustment device, comprising: S1. Determine whether the pumping unit base 1 needs adjustment and the direction of adjustment based on the displays of the four level rulers 2. Specifically, observe the position of the bubble in the middle of the level ruler 2. If the bubble is in the middle of the glass tube, it indicates that the direction is horizontal; if the bubble is biased to one side, it indicates that side is too high and adjustment is needed. Any unevenness in any of the four measurement positions requires adjustment.

[0024] S2. Install the two leveling devices 3 at appropriate positions before and after the pumping unit base 1. Specifically, this includes: Select a connecting chain 3042 of appropriate length and a jack support 302 of appropriate height; Based on the site conditions, four jack supports 302 were placed on the cement foundation 6, and one jack 303 was placed on each jack support 302. Two crossbeams 305 are laid across the pumping unit base 1, and a jack 303 is placed at the bottom of each end of the crossbeams 305. Connect the two ends of the connecting chain 3042 to the crossbeam ring 3041 and the shovel hook 3043 respectively; and put the crossbeam ring 3041 on the crossbeam 305, and hook the shovel hook 3043 onto the pumping unit base 1; Adjust the extension of the jack 303 by manually pumping oil pump 301 to pre-tighten the leveling device 3.

[0025] S3. Loosen the anchor bolts 4 of the pumping unit base and remove the shims 5. Adjust the four manual oil pumps 301 to adjust the extension of the corresponding jacks 303 so that all four level gauges 2 show a horizontal position, that is, the bubble on the level gauge is in the middle position of the glass tube, and at the same time, the gap between the bottom surface of the pumping unit base 1 and the upper surface of the cement foundation 6 meets the requirements.

[0026] S4. Install the shims 5, tighten the anchor bolts 4, retract the jack 303, and check again whether the four spirit levels 2 are level. If they are not level, repeat step S3. If all four spirit levels 2 show that they are level, then the surface oil pump base 1 has been leveled and the adjustment is complete.
