The pumping unit base is a rectangular steel frame welded by I-beams or channel steels, and is placed on a concrete foundation. After long-term use, due to reasons such as foundation subsidence and cement weathering, the pumping unit base becomes unlevel. Every year in the heavy oil oilfield operation area, a large number of pumping unit bases need to be leveled. The unlevel pumping unit base will cause a series of production and environmental protection problems such as the distortion of the central shaft of the pumping unit, the wear of the reducer bearings, and the misalignment of the wellhead and oil leakage.

Specific implementation mode

[0021] The present utility model is not limited by the following embodiments, and the specific implementation mode can be determined according to the technical solution of the present utility model and the actual situation.

[0022] In the present utility model, for the convenience of description, the description of the relative position relationship of each component is carried out according to the layout mode of the attached drawings of the specification. For example, the position relationships such as front, back, up, down, left, and right are determined according to the layout direction of the attached drawings of the specification. Figure 1 The position relationships such as front, back, up, down, left, and right are determined according to the layout direction of the attached drawings of the specification.

[0023] The present utility model will be further described below in conjunction with the embodiments and the attached drawings:

[0024] Embodiment 1: As shown in the attached Figures 1 to 5As shown in the figure, the level adjusting tool for the pumping unit base includes a housing 1, a cover 2 and a rotary handle 3. The right end of the housing 1 is detachably installed with the left end of the cover 2. A strip-shaped cavity 4 with an opening to the right and penetrating up and down is provided at the rear of the right side of the housing 1. A rack 5 with its lower end located below the housing 1 is slidably installed in the strip-shaped cavity 4. A trapezoidal cavity 6 with an opening to the right and narrowing from front to back is provided at the front of the right side of the housing 1. The rear end of the trapezoidal cavity 6 is connected to the strip-shaped cavity 4. Corresponding to the position of the trapezoidal cavity 6, the cover 2 bulges to the right to form an oval housing 7 with a smaller upper part and a larger lower part. The inner cavity of the oval housing 7 is connected to the trapezoidal inner cavity. A speed reduction gear set meshed with the front side of the rack 5 at the rear end is provided in the trapezoidal cavity 6. The left end of the speed reduction gear set is rotatably installed on the inner side wall of the left end of the housing 1, and the right end of the speed reduction gear set is rotatably installed on the oval housing 7. An input hole penetrating left and right is provided in the upper part of the oval housing 7. The input shaft of the speed reduction gear set passes through the input hole and is fixedly installed with the middle part of the rotary handle 3. A locking mechanism is provided between the outer side of the right part of the input shaft of the speed reduction gear set and the right side of the oval housing 7. The locking mechanism can prevent the input shaft of the speed reduction gear set from reversing.

[0025] By setting it in this way, the rotary handle 3 can drive the input shaft of the speed reduction gear set to rotate. The speed reduction gear set can reduce the rotational speed of the input shaft 31 and at the same time increase the output torque of the speed reduction gear set, so as to more labor-savingly drive the rack 5 to slide downward in the strip-shaped cavity 4, causing the housing 1 and the cover 2 to rise relative to the rack 5, realizing a function similar to that of a jack in the prior art. Thus, the operator can use this device to lift the pumping unit base upward alone to restore the pumping unit base to a horizontal state again.

[0026] In the locked state of the locking mechanism, it can effectively prevent the input shaft of the speed reduction gear set from reversing, so that the speed reduction gear set can never reverse, thereby preventing the rack 5 from retracting, keeping the extended length of the rack 5 always unchanged, and then always reliably supporting the pumping unit base, effectively solving the problem that the jack in the prior art cannot bear weight for a long time.

[0027] This device can bear all the weight of the support point of the pumping unit base, meeting the installation and operation requirements of the level adjusting tool.

[0028] During the use process, several such devices can be placed in the lifting points of the type III pumping unit, that is, in each U-shaped operation space between the channel steel base 45 and the cement base 46. The operator manually rotates the rotary handle 3 according to the detection results of a level detector such as a spirit level, and drives the rack 5 to move downward relative to the housing 1 through the speed reduction gear set to increase the height of this device, so as to jack the reducer base back to its original position and make the pumping unit base in a horizontal state again.

[0029] After on-site verification, the longitudinal allowable deviation of the levelness of the pumping unit base is ≤3‰, and the transverse deviation is ≤0.5‰. The time for a single person to level the pumping unit base is 20 minutes per unit, which greatly shortens the shut-in time of the oil well, effectively improves the operation efficiency of leveling the pumping unit base. The adjustment process is flexible, simple and labor-saving, enabling the operators to level the base independently. After deducting the labor cost and the processing cost of this device, the adjustment operation cost is zero, enabling the leveling operation of the pumping unit base to achieve zero accidents, zero injuries and zero pollution. Moreover, it does not require the cooperation of a crane during use and is extremely suitable for oil wells where a crane cannot operate and the well site is small.

[0030] According to requirements, the right end of the housing 1 and the left end of the cover 2 are detachably installed together through threaded fasteners. To facilitate the connection between the housing 1 and the cover 2, in this embodiment, a connecting flange is provided on the outer side of the right end of the housing 1. The left end of the reduction gear set can be fixedly installed on the inner side of the left side wall of the housing 1 through a bearing seat, and the right end of the reducer can also be fixedly installed on the inner side of the right end of the oval housing 7 through a bearing seat, thereby realizing the rotational installation between the reduction gear set and the housing 1 and the cover 2. The reduction gear set can be a single-stage reduction gear set or a multi-stage two-stage reduction gear set in the prior art. To prevent dust, rainwater, etc. from falling into the strip-shaped cavity 4 and at the same time increase the contact area between the upper end of the housing 1 and the pumping unit base, a baffle can be installed at the upper end of the housing 1. The rotary handle 3 can be a handwheel, a flat handle or a trident-shaped handle, etc. in the prior art.

[0031] During specific implementation, the locking mechanism can include a support plate and a hand-tightening bolt. A support plate can be fixedly installed on the outer side of the input shaft of the reduction gear set corresponding to the position between the right end of the oval housing 7 and the rotary handle 3. The other end of the support plate is provided with a through hole from left to right, and a hand-tightening bolt is arranged in the through hole. The left end of the hand-tightening bolt is provided with a number of anti-slip teeth. An annular anti-slip tooth layer can be arranged around the axis of the input shaft 31 of the reduction gear set on the right side of the oval housing 7 corresponding to the position of the hand-tightening bolt. When the anti-slip teeth at the left end of the hand-tightening bolt are tightly pressed against the annular anti-slip tooth layer, the reverse rotation of the input shaft of the reduction gear set can be blocked, preventing the rack 5 from retracting upward.

[0032] The structure of the utility model is reasonable and compact, easy to use and operate simply. By rotating the handle 3, the input shaft of the reduction gear set can be driven to rotate, enabling the reduction gear set to drive the rack 5 to slide downward in the strip cavity 4, lifting the housing 1 and the cover 2 upward relative to the rack 5, thereby lifting the pumping unit base upward to restore the pumping unit base to a horizontal state again. During use, it can be operated by a single person, with high adjustment precision, saving time and effort, greatly shortening the shut-in time of the oil well, effectively improving the efficiency of the operation of leveling the pumping unit base. The adjustment process is flexible, simple and labor-saving, enabling the operator to independently level the operation. After deducting the labor cost and the processing cost of this device, the adjustment operation cost is zero, enabling the operation of leveling the pumping unit base to achieve zero accidents, zero injuries and zero pollution, and no crane is required during use, which is extremely suitable for oil wells where the crane cannot operate and the well site is small.

[0033] According to actual needs, the above-mentioned tool for leveling the pumping unit base can be further optimized and / or improved:

[0034] Embodiment 2: As shown in FIGS. Figures 1 to 3 4 and 5, a fixed clamping seat is fixedly installed on the left side of the housing 1. The fixed clamping seat includes a top plate 8, a back plate 9, an upper limit plate 10, a lower limit plate 11, a reinforcing rib plate 12 and a plug pin 13. The upper end of the housing 1 is fixedly installed together with the middle part of the lower side of the top plate 8. There is a boss 14 on the left side of the lower part of the housing 1, and the upper left end of the boss 14 is fixedly installed together with the lower right end of the back plate 9. The upper right end of the back plate 9 is fixedly installed together with the left end of the top plate 8. The upper limit plate 10 and the lower limit plate 11 are fixedly installed at intervals up and down on the left side of the lower end of the back plate 9, and the left end of the upper limit plate 10 is located to the left of the left end of the lower limit plate 11. A limit card slot 15 can be formed among the lower side of the upper limit plate 10, the upper side of the lower limit plate 11 and the left side of the back plate 9. A reinforcing rib plate 12 is fixedly installed between the middle part of the upper side of the upper limit plate 10 and the middle part of the left side of the back plate 9. There is at least one pin hole 16 penetrating up and down at the left end of the upper limit plate 10, and a plug pin 13 is arranged in each pin hole 16.

[0035] According to requirements, to enhance the installation strength of the back plate 9 and improve the installation strength of the reduction gear set, a reinforcing boss can be provided between the left side of the housing 1 corresponding to the trapezoidal cavity 6 and the back plate 9. In this embodiment, the front part and the rear part of the left end of the upper limit plate 10 are respectively provided with pin holes 16 penetrating up and down, and plug pins 13 are arranged in both pin holes 16.

[0036] By setting it like this, after placing this device on the lifting point, the lifting point is located in the through slot between the cement base 46 on the side of the pumping unit base and the channel steel base 45. Through the limit card slot 15, this device can be clamped on the channel steel base 45 of the five - type pumping unit, that is, the limit card slot 15 is clamped on the upper side wall of the channel steel 47. Since the upper limit plate 10 is longer than the lower limit plate 11, after inserting the bolt 13 into the corresponding pin hole 16, the bolt 13 just abuts against the left side wall of the channel steel 47. Through three - point fixation, it effectively prevents this device from tilting and loosening to the right, thus firmly and reliably fixing and installing this device on the channel steel base 45 of the pumping unit.

[0037] During use, the rack 5 extends downward, and the housing 1 and the fixed clamping seat can lift the channel steel base 45 upward together, so that the channel steel base 45 of the five - type pumping unit returns to horizontal again.

[0038] Example 3: As shown in the appendix Figure 2 , 5 As shown, an auxiliary top - pressing mechanism is provided on the lower left side of the lower limit plate 11. The auxiliary top - pressing mechanism includes a limit sleeve 17, a top rod 18, a T - shaped base 19, and a rod - shaped handle 20. The lower left side of the lower limit plate 11 is fixedly installed with the upper end of the limit sleeve 17. The inner side of the sleeve is sleeved with the outer side of the upper end of the top rod 18. The lower outer side of the top rod 18 is threadedly connected with a T - shaped base 19. A handle mounting hole that penetrates left and right is provided in the middle of the top rod 18, and a rod - shaped handle 20 is slidably installed in the handle mounting hole.

[0039] By setting it like this, the auxiliary top - pressing mechanism can form another support between the inner side of the lower side wall of the channel steel 47 and the lower side wall of the fixed clamping seat, effectively improving the clamping strength between the fixed clamping seat and the channel steel base 45 of the five - type pumping unit, and effectively preventing the fixed clamping seat from tilting, loosening, and shaking to the left during long - term use.

[0040] During use, the rod - shaped handle 20 can move left and right along the handle mounting hole to avoid the rod - shaped handle 20 abutting against the channel steel base 45. By rotating the top rod 18 with the rod - shaped handle 20, the length of the auxiliary top - pressing mechanism can be adjusted so that the auxiliary top - pressing mechanism just fits into the channel steel 47. To prevent the top rod 18 from retracting, the connecting thread between the top rod 18 and the T - shaped base 19 can be a trapezoidal thread that can achieve self - locking in the prior art or other self - locking threads that can be reused repeatedly.

[0041] Example 4: As shown in the appendix Figures 1 to 5As shown in the figure, the input shaft of the reduction gear set is drivingly connected to the rotary handle 3 through a steering gear set. The steering gear set includes a driving bevel gear 21, a driven bevel gear 22, a main transmission rod 23, an L-shaped bracket 24, and a rolling bearing 25. The outer side of the right end of the input shaft of the reduction gear set is drivingly connected to the driven bevel gear 22. The rear part of the driven bevel gear 22 meshes with the left part of the driving bevel gear 21. The middle part of the rear side of the driving bevel gear 21 is fixedly installed with a main transmission rod 23 whose rear end is located behind the housing 1. The outer side of the rear end of the main transmission rod 23 is fixedly installed with the inner side of the middle part of the rotary handle 3. The outer side of the front part of the main transmission rod 23 is sleeved with an L-shaped bracket 24. The left end of the L-shaped bracket 24 is detachably installed at the corresponding position on the right side of the cover body 2. A rolling bearing 25 is provided between the L-shaped bracket 24 and the main transmission rod 23.

[0042] By setting it like this, the rotary handle 3 and the input shaft of the reduction gear set are drivingly connected through the bevel gear set, which can change the installation direction of the rotary handle 3, enable the rotary handle 3 to be installed on the side of the device, make the rotation direction of the rotary handle 3 perpendicular to the laying direction of the channel steel 47 of the channel steel base 45, and is more convenient for the operator to operate the handle and saves the operation space.

[0043] According to requirements, to improve the interchangeability of parts, the L-shaped bracket and the rolling bearing 25 can also be replaced with a bearing seat in the prior art.

[0044] Example 5: As shown in the appendix Figure 4 As shown in the figure, it further includes an outer protective shell 26. An outer protective shell 26 that can enclose the steering gear set is detachably installed on the right side of the cover body 2 corresponding to the outer side position of the oval housing 7.

[0045] By setting it like this, the protective shell can be more conducive to preventing the bevel gear set from being eroded by rain, sand, dust, etc., protecting the lubrication of the bevel gear set, and preventing the bevel gear set from failing.

[0046] Example 6: As shown in the appendix Figures 1 to 2 As shown in FIGS. 4 to 5, the locking mechanism includes a ratchet 27, a detent pawl 28, a rotating shaft 29, and a fixing plate 30. The ratchet 27 is fixedly installed on the outer side of the input shaft of the reduction gear set. The outer side of the input shaft of the reduction gear set corresponding to the right side position of the oval housing 7 is sleeved with a fixing plate 30 whose upper end is located above the oval housing 7. The lower part of the fixing plate 30 is detachably installed on the right side of the oval housing 7. The upper end of the fixing plate 30 is rotatably installed with a rotating shaft 29. The outer side of the right end of the rotating shaft 29 is rotatably installed with a detent pawl 28. The lower end of the detent pawl 28 meshes with the upper rear end of the ratchet 27.

[0047] With such a setting, under the action of its own weight, the lower end of the stop pawl 28 can automatically engage with the upper rear end of the ratchet wheel 27, so that the driven bevel gear 22 can only rotate clockwise and cannot rotate in the reverse direction. It can automatically lock the relative position between the rack 5 and the reduction gear set, thereby automatically fixing the relative position between the rack 5 and the housing 1, simplifying the operation steps of the operator, and saving more time and effort.

[0048] When unlocking, the operator reversely rotates the stop pawl 28 with one hand to separate the lower end of the stop pawl 28 from the ratchet wheel 27, and operates the rotary handle 3 to reverse with the other hand, then the rack 5 can be retracted into the housing 1, and the device can be removed.

[0049] Embodiment 7: As shown in the attached Figures 1 to 5 figure, the reduction gear set includes an input shaft 31, an intermediate shaft 32, an output shaft 33, a first gear 34, a second gear 35, a third gear 36, a fourth gear 37 and a fifth gear 38.
