Specific embodiments

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The purpose of the present invention is to provide a multi-functional mechanical equipment for an oil production system, which solves the impact of motor commutation on equipment components, realizes the reciprocating commutation movement of the counterweight under the condition of the same rotation direction of the driving mechanism, ensures the reliability and stability of the equipment, and improves the oil production efficiency of the equipment at the same time.

[0032] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] As Figures 1 to 11 shown, this embodiment provides a multi-functional mechanical equipment for an oil production system, including: a frame 1 and a driving mechanism 2, a driving sprocket 3, a driven sprocket 4, a reversing mechanism 5, a counterweight 6, and a lifting belt 7 arranged on the frame 1. The output shaft of the reducer 10 of the driving mechanism 2 is connected to the driving sprocket 3 through a shaft hub. The driving sprocket 3 is connected to the driven sprocket 4 through a chain 27. The reversing mechanism 5 is connected to the chain 27 and is also connected to the counterweight 6. The counterweight 6 realizes reciprocating linear motion along the frame 1 through the rolling wheels on both sides of the counterweight 6. The lifting belt 7 is preferably a wire rope core lifting belt. One end of the lifting belt 7 is connected to the counterweight 6. The lifting belt 7 bypasses the drum on the frame 1. The other end of the lifting belt 7 is connected to the well rod. The driving mechanism 2 drives the driving sprocket 3 to rotate, and the chain 27 drives the reversing mechanism 5 to move, thereby realizing the reciprocating motion of the counterweight 6 and the other end of the lifting belt 7.

[0034] Specifically, in this embodiment, the drive mechanism 2 includes a motor 8, a brake 9, and a reducer 10. The power output end of the motor 8 is connected to the reducer 10 through a coupling 11. The brake 9 is arranged between the motor 8 and the reducer 10. The brake 9 is preferably manually braked. The brake 9 is used for braking the motor 8 and the reducer 10. The power output end of the reducer 10 is connected to the hub of the driving sprocket 3. The tower-type pumping unit in the prior art uses a high-speed motor 8 connected to the reducer through a belt or other transmission means. Long-term use will cause wear of the belt. Under the condition of belt wear, it not only affects the pumping output, but also increases the manual maintenance cost due to the replacement of the belt. It is necessary to replace the belt at least four times a year on average. This embodiment adopts a structure in which the motor 8, the coupling 11 (with a brake 9) and the reducer 10 are directly connected. In this embodiment, the low-speed high-torque motor, the hub coupling are directly connected to the reducer 10, which not only reduces the installation difficulty, but also provides a certain degree of buffering, making the transmitted torque more stable and the efficiency higher, solving the problem of belt wear in the prior art, increasing the pumping output, and at the same time, it can also be connected to the reducer 10 through the brake 9 at the other end of the coupling 11. That is, while the motor 8 is connected to the reducer 10 through the coupling 11, the brake 9 can perform emergency braking in an emergency to stop the system and ensure the requirements of other on-site operations.

[0035] In this embodiment, the brake can have two methods: one is a manual brake, which uses a lead screw link mechanism to drive the braking member; the other is an automatic brake, such as an electromagnetic brake, an electro-hydraulic brake, etc.

[0036] In this embodiment, the commutation mechanism 5 includes a commutation wheel fixing plate 12, a connecting member, and a roller 15. The connecting member is located on one side of the commutation wheel fixing plate 12. The connecting member includes a connecting member body 13 and a pin shaft 14. The connecting member body 13 and the chain 27 are connected by the pin shaft 14. The connecting member is rotatably connected to the commutation wheel fixing plate 12. The roller 15 is arranged on the commutation wheel fixing plate 12 and is rotatably connected to the commutation wheel fixing plate 12. The roller 15 is located in the chute 16 of the counterweight 6. The chute 16 of the counterweight 6 is horizontally arranged, and the roller 15 can roll in the chute 16 of the counterweight 6. The driving mechanism 2 drives the driving sprocket 3 to rotate, the driving sprocket 3 drives the chain 27 to move, and the chain 27 drives the commutation mechanism 5 to move through the connecting member. When the position where the commutation mechanism 5 is connected to the chain 27 is on one side of the driving sprocket 3 or the driven sprocket 4, the chain 27 drives the commutation mechanism 5 and the counterweight 6 to move upward or downward. At this time, the position of the roller 15 in the chute 16 is close to one side of the driving sprocket 3 or the driven sprocket 4. When the position where the commutation mechanism 5 is connected to the chain 27 is commutated from one side of the driving sprocket 3 or the driven sprocket 4 to the other side of the driving sprocket 3 or the driven sprocket 4, the connecting member and the commutation wheel fixing plate 12 rotate relative to each other. At the same time, the roller 15 moves in the chute 16, moving from one end of the chute 16 to the other end. The position where the commutation mechanism 5 is connected to the chain 27 is on the other side of the driving sprocket 3 or the driven sprocket 4, and the counterweight 6 completes commutation. As the driving mechanism 2 drives the driving sprocket 3 to rotate, the chain 27 drives the commutation mechanism 5 and the counterweight 6 to move downward or upward. In this embodiment, under the condition of maintaining the same-direction rotation, the motor 8 drives the driving sprocket 3 to rotate, and the reciprocating linear motion of the counterweight 6 is realized through the commutation mechanism 5.

[0037] This embodiment further includes a sprocket wheel pitch adjusting mechanism, which includes a support frame 17, a fixing plate 18, an adjusting plate 19, a jacking structure 22 and a guiding pin shaft 23. The shaft seat 20 of the driven sprocket 4 is arranged on the adjusting plate 19. The adjusting plate 19 is located above the fixing plate 18. The adjusting plate 19 and the fixing plate 18 are connected by fixing bolts 21. Preferably, there are four fixing bolts 21, which are respectively arranged at the four corners. The lower end of the guiding pin shaft 23 is welded to the fixing plate 18. The guiding pin shaft 23 passes through the positioning hole of the adjusting plate 19. The fixing plate 18 is arranged on the support frame 17. The jacking structure 22 is preferably a jack. The jacking structure 22 is arranged on the support frame 17. The telescopic end of the jacking structure 22 can pass through the through hole on the fixing plate 18 and contact the adjusting plate 19. The support frame 17 is arranged on the frame 1. When it is necessary to adjust the center distance between the driving sprocket 3 and the driven sprocket 4, loosen each fixing bolt 21, extend or contract the jacking structure 22 to change the distance between the adjusting plate 19 and the fixing plate 18. When the appropriate position is adjusted, pads can be appropriately added. After the adjustment is completed, tighten the fixing bolts 21. Each guiding pin shaft 23 ensures that during the adjustment process, the adjusting plate 19 and the shaft seat 20 of the driven sprocket 4 can only move in the vertical direction. The sprocket wheel pitch adjusting mechanism can accurately complete the adjustment of the center distance between the driving sprocket 3 and the driven sprocket 4, thus ensuring the normal operation of the transmission.

[0038] This embodiment further includes a lubricating oil pump 28. The lubricating oil pump 28 is arranged on the frame 1. The lubricating oil pump 28 is used to add lubricating oil to the chain 27, the driving sprocket 3 and the driven sprocket 4. The lubricating oil pump 28 is controlled by a PLC and can complete the lubrication work regularly and quantitatively, realizing economical and effective lubrication and ensuring the reliable operation of the chain 27, the driving sprocket 3 and the driven sprocket 4.

[0039] During oilfield maintenance operations, the pumping unit needs to be moved backward by a certain distance. Usually, large special equipment vehicles are required for the machine moving operation, resulting in relatively high costs. To solve the problem of difficult machine moving, this embodiment further includes a machine moving mechanism. The machine moving mechanism includes machine moving wheels 24, a machine moving drive structure 25, a fixed seat, and a positioning column structure. The machine moving wheels 24 can be connected to the frame 1 to separate the frame 1 from the installation foundation, converting the sliding friction into rolling friction, greatly reducing the friction resistance during machine moving, thereby reducing the driving force during machine moving and saving energy consumption. The machine moving drive structure 25 is preferably a short-stroke hydraulic cylinder, and the stroke of the machine moving drive structure 25 is preferably 800 mm. The two-stage or multi-stage machine moving operation mode is adopted to reduce the length of the bottom base of the frame 1, that is, to reduce the floor area of the multi-functional mechanical equipment of the oil production system. The same machine moving distance can be achieved by moving the machine through the machine moving drive structure 25. For example, when using a short-stroke hydraulic cylinder with a stroke of 800 mm for machine moving, the short-stroke hydraulic cylinder can achieve a machine moving distance of 1500 mm through the two-stage machine moving operation. The power output end of the machine moving drive structure 25 is connected to the frame 1, and the machine moving drive structure 25 can drive the frame 1 to move. The fixed end of the machine moving drive structure 25 is provided with a connecting pin 29. The groove 31 of the fixed seat 30 opens upward, and the connecting pin 29 can enter the groove 31 of the fixed seat 30. The fixed seat 30 is used to be arranged in the pit 32 of the installation foundation. During machine moving, the fixed seat 30 is placed in the pit 32 of the installation foundation, and the connecting pin 29 at the fixed end of the machine moving drive structure 25 is arranged in the groove 31 of the fixed seat 30. The fixed seat 30 provides a supporting force for the machine moving drive structure 25. The machine moving drive structure 25 works to complete one machine moving. When continuous machine moving is required, the connecting pin 29 is pulled out or lifted from the groove 31 of the fixed seat 30 to disengage the connecting pin 29 from the fixed seat 30. The fixed seat 30 is moved to another pit 32 of the installation foundation, and the machine moving drive structure 25 is connected to the fixed seat 30 again through the connecting pin 29 for the second machine moving. The machine moving drive structure 25 of this embodiment adopts the connection method of the connecting pin 29 and the fixed seat 30, which is easy to install and convenient for on-site construction. Each positioning column structure is located on both sides of the frame 1 respectively. Each positioning column structure includes a number of positioning columns 26 arranged along the moving direction of the frame 1, and each positioning column 26 is fixed on the installation foundation. In this embodiment, by installing machine moving wheels 24 at the lower part of the tower-type pumping unit, the friction resistance between the pumping unit and the installation foundation is reduced, so that the thrust required for the machine moving operation is reduced, thereby avoiding damage to the equipment due to excessive force. Then, the machine moving drive structure 25 is used to realize the forward and backward movement of the pumping unit. The positioning column structures on both sides can ensure that the pumping unit moves backward along a straight line, avoiding position deviation, and can also ensure its reliable return to its original position during reset. After oilfield operations, after the pumping unit returns to its original position under the action of the machine moving drive structure 25, the machine moving wheels 24 are removed and the pumping unit is fixed, and the machine moving operation is completed. This embodiment reduces the usage amount of relevant machinery and personnel through the machine moving mechanism, and the operation is simple and economical.

[0040] In this embodiment, a chain 27 is used for transmission, and power is provided by a motor 8 and a reducer 10 to realize the rotational motion of the driving sprocket 3, the driven sprocket 4 and the chain 27. Then, through the reversing mechanism 5 fixed to the chain 27 and the chute 16 on the counterweight 6, while the driving sprocket 3, the driven sprocket 4 and the chain 27 are rotating, the reversing mechanism 5 makes reciprocating motions on both sides of the driving sprocket 3 and the driven sprocket 4, thereby realizing the reciprocating motion of the counterweight 6. In this embodiment, the motor 8 drives the driving sprocket 3, so that the driving sprocket 3, the driven sprocket 4 and the chain 27 always move in the same direction. The motor 8 of this embodiment rotates continuously in the forward direction and does not need to reverse to realize the reciprocating linear motion of the counterweight 6. It can not only solve the impact of the forward and reverse rotation of the motor 8 on the equipment parts, but also overcome the impact load faced by the forward and reverse rotation of the motor 8. On the basis of ensuring the smooth reciprocating motion of the counterweight 6, it can also realize smooth operation at a higher speed, thereby improving the work efficiency and achieving higher production capacity of the tower-type pumping unit.

[0041] After the pumping unit has worked for a period of time, oilfield workers need to carry out maintenance operations on the oil well. At this time, a rod pulling operation needs to be carried out on the rod string. At this time, the multi-functional tower-type pumping unit can replace the workover rig to carry out the rod pulling operation on the sucker rod, realizing the composite functions of pumping and workover, reducing the investment in mechanical equipment, and greatly reducing the maintenance cost.

[0042] In this embodiment, the machine moving is realized through the machine moving mechanism, and it no longer relies on special equipment vehicles for machine moving, saving the workover cost.

[0043] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
