Description

Technical Field

[0001] The utility model relates to the technical field of oil production machinery, in particular to an upper platform assembly structure of a tower type oil pumping unit. Background Art

[0002] Energy conservation has become a very important issue in the context of energy shortage and severe power shortage. Pumping units are the main production equipment in oil fields. For low permeability oil fields, the oil level is formed slowly, and most pumping units are idling for a long time, which will waste a lot of electricity, cause wear on the pumping units, and reduce the life of the pumping units.

[0003] Publication No. CN105545256B discloses a balanced tower type oil pumping unit. By adjusting the weight of the weight-adjusting box, when the oil pumping unit is operating normally, the driving platform rotates around the hinge axis, and there is a difference in the driving force of the driving ropes on both sides of the driving wheel. Then, the difference in traction force between the sucker rod traction rope and the counterweight box traction rope on the whole machine is reduced accordingly. At this time, the driving rope overcomes part of the friction force to work, thus producing energy-saving effects, reducing oil pumping unit wear, and extending the service life of the oil pumping unit. When the driving force difference is 1 / 2 of the weight of the oil column, the traction force of the sucker rod traction rope and the counterweight box traction rope is equal, achieving balance, and the energy-saving effect is optimal. However, the patent still has the following problems in actual use:

[0004] By adjusting the weight of the counterweight box, the pumping unit can operate normally, and the driving platform rotates around the hinge axis. There is a difference in the driving force of the driving ropes on both sides of the driving wheel, and the traction force difference between the sucker rod traction rope and the counterweight box traction rope on the whole machine is reduced accordingly. At this time, the driving rope overcomes a part of the friction force and works, thus producing an energy-saving effect. However, when installing and splicing the upper platform, most of them are done by welding, which makes it difficult to disassemble the upper platform when disassembling the main body, and the upper platform needs to be cut and disassembled, which not only increases the workload of the staff, but also increases the cost to a certain extent.

There is a difference in the driving force of the driving ropes on both sides of the driving wheel, and the traction force difference between the sucker rod traction rope and the counterweight box traction rope on the whole machine is correspondingly reduced. At this time, the driving rope overcomes a part of the friction force to work, thereby producing an energy-saving effect. However, when the upper platform is installed and spliced, most of them are done by welding, which makes it difficult to disassemble the upper platform when the main body is disassembled, and the upper platform needs to be cut and disassembled, which not only increases the workload of the staff, but also increases the cost to a certain extent.

At the same time, the oil pumping device 5 is the existing technology, and the existence of the connecting plate 6 facilitates the operation of the oil pumping device 5.

[0030] A thread groove 904 is provided inside the fixing block 903, a clamping rod 905 is slidably connected inside the thread groove 904, a clamping plate 906 is fitted and connected to the surface of the clamping plate 905, a fixing plate 907 is fixedly connected to the bottom surface of the clamping plate 906, the fixing plate 907 is fixedly connected to the thread groove 904, the fixing plate 907 is connected through the clamping rod 905, a rotating block 908 is threadedly connected inside the thread groove 904, the rotating block 908 is fitted and connected to the clamping plate 906, and bolts 909 are connected through the two sides of the fixing frame 902. Figure 4 , 5 As shown, after the staff uses tools to install the bolts 909 on both sides of the connecting block 901 on the support frame 2, they push the clamping rod 905 to make the clamping rod 905 engage with the clamping groove 12, and then rotate the rotating block 908 so that the rotation of the rotating block 908 can drive the movement of the clamping plate 906. Through the movement of the clamping plate 906, the clamping plate 906 clamps the clamping rod 905, so that the clamping rod 905 can be limited. At the same time, the clamping plate 906 is made of rubber, so that the friction between the clamping plate 906 and the clamping rod 905 is large, thereby reducing the movement between the clamping rod 905 and the clamping plate 906. At the same time, the bottom of the rotating block 908 is provided with a thread texture threadedly connected to the thread groove 904, so that when not interfered by human power, there will be no rotation between the rotating block 908 and the thread groove 904, which makes it easy to install the platform plate 3, thereby improving the installation efficiency of the platform plate 3.

[0031] The top surface of the bottom plate 1 is connected with fixing nails 8 on both sides. Figure 1 As shown, the fixing nails 8 facilitate the installation of the bottom plate 1 just above the wellhead, thereby facilitating the production operation of the oil pumping device 5.

[0032] A spring 10 is sleeved on one side surface of the slide bar 7 near the bottom, a rubber plate 11 is fixedly connected to the top surface of the spring 10, and a bottom surface of the spring 10 is fixedly connected to the bottom plate 1. Figure 3As shown, when the counterweight in the oil pumping device 5 descends, the counterweight is limited by the action of the sliding rod 7. At the same time, when the counterweight descends and contacts the rubber plate 11, the spring 10 and the rubber plate 11 make the rubber plate 11 descend. The descending of the rubber plate 11 can squeeze the spring 10, so that the spring 10 is deformed. At the same time, the spring 10 is acted on by the sliding rod 7 so that the spring 10 will not swing greatly when rebounding, so as to achieve the purpose of buffering, thereby avoiding direct contact between the counterweight and the ground. At the same time, the spring 10 is a rubber composite spring in the prior art, and the elastic force of the rubber composite spring is relatively large.

[0033] The support frame 2 is symmetrically provided with slots 12 on both sides near the top, and the slots 12 are engaged with the clamping rods 905. Figure 4 As shown, the engagement connection between the card slot 12 and the card rod 905 makes it easy to splice and install the platform board 3. At the same time, the bolts 909 can fix the fixing frame 902, the connecting block 901 and the supporting frame 2 together, thereby completing the installation of the platform board 3.

[0034] Working principle: Before using the upper platform assembly structure of this tower type oil pumping unit, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, first, by setting the fixing assembly 9, when installing the platform board 3, the platform board 3 is lifted and placed on the support frame 2 by a crane, and then the staff uses a ladder to ascend to install the platform board 3. At the same time, the staff uses tools to install the bolts 909 on both sides of the connecting block 901 on the support frame 2, and then pushes the clamping rod 905 to make the clamping rod 905 engage with the clamping groove 12, and then rotates the rotating block 908 so that the rotation of the rotating block 908 can drive the movement of the clamping plate 906, and the movement of the clamping plate 906 makes the clamping plate 906 will clamp the clamping rod 905, so that the clamping rod 905 can be limited. At the same time, the clamping plate 906 is made of rubber, so that the friction between the clamping plate 906 and the clamping rod 905 is relatively large, thereby reducing the movement between the clamping rod 905 and the clamping plate 906. At the same time, the bottom of the rotating block 908 is provided with a thread texture threadedly connected to the thread groove 904, so that when there is no human interference, there will be no rotation between the rotating block 908 and the thread groove 904, thereby facilitating the installation of the platform plate 3, thereby improving the installation efficiency of the platform plate 3.

[0035] Secondly, by providing the slide bar 7, the spring 10, and the rubber plate 11, when the counterweight in the oil pumping device 5 descends, the slide bar 7 is used to limit the counterweight, and at the same time, when the counterweight descends and contacts the rubber plate 11, the spring 10 and the rubber plate 11 make the rubber plate 11 descend. The descending of the rubber plate 11 can squeeze the spring 10, so that the spring 10 is deformed. At the same time, the slide bar 7 is used to prevent the spring 10 from swinging greatly when it rebounds, so as to achieve the purpose of buffering, thereby preventing the counterweight from directly contacting the ground.
