DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a multifunctional mechanical equipment for an oil production system, which solves the impact of motor reversing on equipment parts and realizes the reciprocating reversing movement of the counterweight body of the driving mechanism under the same steering condition, thereby ensuring the reliability and stability of the equipment and improving the oil production efficiency of the equipment.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 11 As shown, this embodiment provides a multifunctional 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 hub, the driving sprocket 3 and the driven sprocket 4 are connected through a chain 27, the reversing mechanism 5 is connected to the chain 27, and the reversing mechanism 5 is 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 steel wire rope core lifting belt, one end of the lifting belt 7 is connected to the counterweight 6, the lifting belt 7 passes around the drum on the frame 1, and 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 driving 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 a manual brake. 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 pumping unit of the prior art adopts a high-speed motor 8 connected to the reducer through a belt or other transmission method. Long-term use will cause belt wear. Under the condition of belt wear, not only the oil extraction output is affected, but also the replacement of the belt increases the labor maintenance cost. The belt needs to be replaced at least four times per year on average. The present embodiment adopts a structure in which the motor 8, the coupling 11 (with the brake 9) and the reducer 10 are directly connected. The present embodiment directly connects the reducer 10 through a low-speed and high-torque motor and a hub coupling, which not only reduces the difficulty of installation, but also provides a certain degree of buffering, making the torque transmission more stable and more efficient, solving the problems caused by belt wear in the prior art and increasing the oil extraction output. At the same time, the brake 9 at the other end of the coupling 11 can also be connected to the reducer 10, which not only realizes that the motor 8 is connected to the reducer 10 through the coupling 11, but also the brake 9 can implement emergency braking in an emergency situation to realize the parking of the system and ensure the needs of other operations on site.

[0035] In this embodiment, there are two types of brakes: one is a manual brake, which uses a screw-connecting rod mechanism to drive the brake member; the other is an automatic brake, such as an electromagnetic brake, an electric hydraulic brake, etc.

[0036] In this embodiment, the reversing mechanism 5 includes a reversing wheel fixing plate 12, a connecting member and a roller 15. The connecting member is located on one side of the reversing wheel fixing plate 12. The connecting member includes a connecting member body 13 and a pin 14. The connecting member body 13 and the chain 27 are connected by the pin 14. The connecting member is rotationally connected to the reversing wheel fixing plate 12. The roller 15 is arranged on the reversing wheel fixing plate 12. The roller 15 is rotationally connected to the reversing wheel fixing plate 12. The roller 15 is located in the slide groove 16 of the counterweight body 6. The slide groove 16 of the counterweight body 6 is horizontally arranged, and the roller 15 can roll in the slide groove 16 of the counterweight body 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 reversing mechanism 5 to move through the connecting piece; when the position where the reversing mechanism 5 is connected to the chain 27 is located on one side of the driving sprocket 3 or the driven sprocket 4, the chain 27 drives the reversing mechanism 5 and the counterweight 6 to move upward or downward. At this time, the position of the roller 15 in the slide groove 16 is close to one side of the driving sprocket 3 or the driven sprocket 4; when the position where the reversing mechanism 5 is connected to the chain 27 is located on the driving sprocket 3 or the driven sprocket 4, the chain 27 drives the reversing mechanism 5 and the counterweight 6 to move upward or downward. During the process of reversing one side of the wheel 4 to the other side of the driving sprocket 3 or the driven sprocket 4, the connecting piece and the reversing wheel fixing plate 12 rotate relative to each other. At the same time, the roller 15 moves in the slide groove 16 from one end of the slide groove 16 to the other end of the slide groove 16. The position where the reversing mechanism 5 is connected to the chain 27 is located on the other side of the driving sprocket 3 or the driven sprocket 4. The counterweight 6 completes the reversal. As the driving mechanism 2 drives the driving sprocket 3 to rotate, the chain 27 drives the reversing mechanism 5 and the counterweight 6 to move downward or upward. In this embodiment, the motor 8 drives the driving sprocket 3 to rotate while maintaining the same direction of rotation, and realizes the reciprocating linear motion of the counterweight 6 through the reversing mechanism 5.

[0037] The present embodiment also includes a sprocket wheel spacing adjustment mechanism, which includes a support frame 17, a fixed plate 18, an adjustment plate 19, a lifting structure 22 and a guide pin shaft 23. The shaft seat 20 of the driven sprocket 4 is arranged on the adjustment plate 19, and the adjustment plate 19 is located above the fixed plate 18. The adjustment plate 19 and the fixed plate 18 are connected by fixing bolts 21. The fixing bolts 21 are preferably four and are respectively arranged at the four corners. The lower end of the guide pin shaft 23 is welded to the fixed plate 18, and the guide pin shaft 23 passes through the positioning hole of the adjustment plate 19. The fixed plate 18 is arranged on the support frame 17. The lifting structure 22 is preferably a jack. The lifting structure 22 is arranged on the support frame 17. The telescopic end of the lifting structure 22 can pass through the through hole on the fixed plate 18 and contact the adjusting plate 19. The support frame 17 is arranged on the frame 1. When the center distance between the driving sprocket 3 and the driven sprocket 4 needs to be adjusted, the fixing bolts 21 are loosened, and the lifting structure 22 is extended or contracted to change the distance between the adjustment plate 19 and the fixed plate 18. When the adjustment is to a suitable position, a pad can be added appropriately. After the adjustment is completed, the fixing bolts 21 are tightened. The guide pins 23 ensure that the adjustment plate 19 and the shaft seat 20 of the driven sprocket 4 can only move in the vertical direction during the adjustment process. The sprocket wheel spacing adjustment mechanism can accurately complete the adjustment of the center distance between the driving sprocket 3 and the driven sprocket 4, thereby ensuring the normal operation of the transmission.

[0038] The present embodiment further includes a lubricating oil pump 28, which is disposed on the frame 1 and 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 lubrication work in a timely and quantitative manner, achieve economical and effective lubrication, and ensure 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 for a distance, which usually requires a large special equipment vehicle to move the unit, resulting in high costs. In order to solve the problem of difficult unit movement, the present embodiment also includes a unit movement mechanism, which includes a unit movement wheel 24, a unit movement drive structure 25, a fixed seat and a positioning column structure. The unit movement wheel 24 can be connected to the frame 1 to separate the frame 1 from the installation base, converting the sliding friction force into rolling friction force, greatly reducing the friction resistance of the unit movement, thereby reducing the driving force during the unit movement and saving energy consumption; the unit movement drive structure 25 is preferably a short-stroke hydraulic cylinder, and the unit movement drive structure 25 is preferably a short-stroke hydraulic cylinder. The stroke of the machine driving structure 25 is preferably 800mm, and a 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 space of the multifunctional mechanical equipment of the oil production system. The machine moving distance can also be achieved by moving the machine through the machine moving driving structure 25. For example, a short-stroke hydraulic cylinder with a stroke of 800mm is used for moving the machine. The short-stroke hydraulic cylinder can also achieve a moving distance of 1500mm through a two-stage machine moving operation; the power output end of the machine moving driving structure 25 is connected to the frame 1, and the machine moving driving structure 25 can drive the frame 1 to move. The fixed end of the moving structure 25 is provided with a connecting pin 29, and the groove 31 of the fixing seat 30 opens upward, and the connecting pin 29 can enter the groove 31 of the fixing seat 30. The fixing seat 30 is used to be set in the pit 32 of the installation base. When moving the machine, the fixing seat 30 is placed in the pit 32 of the installation base. The connecting pin 29 of the fixed end of the moving machine driving structure 25 is set in the groove 31 of the fixing seat 30. The fixing seat 30 provides support for the moving machine driving structure 25. The moving machine driving structure 25 works and completes one machine moving. When it is necessary to continue moving the machine, the connecting pin 29 is removed from the fixing seat The connecting pin 29 is pulled out or lifted from the groove 31 of the frame 30, so that the connecting pin 29 is disengaged from the fixing seat 30, and the fixing seat 30 is moved to another pit 32 of the installation foundation. The moving machine driving structure 25 is connected to the fixing seat 30 again through the connecting pin 29 to move the machine for the second time. The moving machine driving structure 25 of this embodiment adopts the method of connecting the connecting pin 29 with the fixing seat 30, which is easy to install and convenient for on-site construction; each positioning column structure is respectively located on both sides of the frame 1, and each positioning column structure includes a plurality 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, the moving machine wheel 24 is installed at the lower part of the tower pumping unit to reduce the friction resistance between the pumping unit and the installation foundation, thereby reducing the thrust required for the moving operation, thereby avoiding damage to the equipment due to excessive force, and then using the moving machine driving structure 25 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 to avoid position deviation, and can also ensure that it can reliably return to its original position when resetting. After the oilfield operation, the pumping unit is restored to its original position under the action of the moving unit driving structure 25, the moving unit wheel 24 is removed, the pumping unit is fixed, and the moving unit operation is completed. This embodiment reduces the use of related machinery and personnel through the moving unit mechanism, and the operation is simple and economical.

[0040] The present embodiment adopts chain 27 transmission, and the power is provided by motor 8 and reducer 10 to realize the rotational movement of driving sprocket 3, driven sprocket 4 and chain 27, and then through the reversing mechanism 5 fixed to the chain 27 and the slide groove 16 on the counterweight body 6, while the driving sprocket 3, driven sprocket 4 and chain 27 rotate, the reversing mechanism 5 completes reciprocating motion on both sides of the driving sprocket 3 and the driven sprocket 4, thereby realizing the reciprocating motion of the counterweight body 6. The present embodiment drives the driving sprocket 3 by the motor 8, so that the driving sprocket 3, the driven sprocket 4 and the chain 27 always move in the same direction. The motor 8 of the present embodiment rotates forward continuously without reversing, so as to realize the reciprocating linear motion of the counterweight body 6, which 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 body 6, it can also realize the smooth operation at a higher speed, thereby improving the working efficiency and realizing the higher production capacity of the tower pumping unit.

[0041] After the pumping unit has been working for a period of time, the oilfield workers need to perform maintenance operations on the oil well, and they need to pull out the well rods. At this time, the multifunctional tower pumping unit can replace the well repairing unit and pull out the pumping rods, thus realizing the combined functions of pumping and well repairing, reducing the investment in mechanical equipment and greatly reducing maintenance costs.

[0042] This embodiment realizes the machine moving through the machine moving mechanism, and no longer relies on special equipment vehicles to move the machine, thus saving well repair costs.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
