Description

Technical Field

[0001] The utility model relates to the technical field of oilfield pumping unit maintenance, in particular to a multifunctional maintenance tool for a suspension rope and bare rod of an oil pumping unit. Background Art

[0002] During the oil extraction process, the suspension rope (braid) of the oil pump, as a component connecting the donkey head and the bare rod, plays a very important role in the operation of the equipment; but since the mining environment is generally harsh, with much rain and strong sandstorms in spring and drought in summer, sand adheres to the braid. The sand is highly alkaline and is easily attached to the braid for a long time, causing the braid to rust and break, so the braid needs to be maintained frequently. Usually, the maintenance of the oil pump braid is done manually, climbing to the top of the donkey head and manually using an oil pot to pour oil along the braid. This has great safety risks and poor maintenance effects. The oil has the problem of drifting and polluting the well site, and the surface of the braid cannot be cleaned, and safety and timeliness cannot be guaranteed. At the same time, when personnel stand on the operating table to maintain the rope braid, they can only maintain part of the rope braid, not all of it. There is a high risk of personnel climbing and there are certain hidden dangers. Utility Model Content

[0029] Embodiment 1:

[0030] like Figure 1 , 2 4, a multifunctional maintenance tool for a suspended rope polished rod of an oil pumping unit, comprising: a rust removal and oil brushing device and a medium conveying device;

[0031] The rust removal and oil brushing device comprises: a cavity 2 formed by two semi-cylindrical cavities with aligned sides, one end of the semi-cylindrical cavity side is connected by a cavity connecting hinge 8, and the other end is provided with a locking device 3, a medium conveying hole 4 is provided in the middle of the outer side of the semi-cylindrical cavity, a medium conveying rod connection 7 is provided below the medium conveying hole 4, a brush connecting hole 5 is provided at the upper part of the inner side of the semi-cylindrical cavity, a cleaning brush 12 connected to the cavity 2 through the brush connecting hole 5, and a cavity sponge 13 is installed below the cleaning brush 12;

[0032] The medium conveying device comprises: a medium conveying rod 9, a medium conveying pump 15 connected to the medium conveying rod 9; a connecting ring 14 is provided at the upper end of the medium conveying rod 9, a medium outlet 11 is provided near the connecting ring 14, and a medium inlet 10 is provided at the lower end of the medium conveying rod 9;

[0033] The medium conveying device is rotatably connected to the medium conveying rod connection 7 on the rust removal and oil brushing device through the connecting ring 14.

[0034] When the maintenance personnel are working, they close the cavity and wrap the hair braid in the middle, use the cleaning brush and sponge in the cavity to mix the medium and maintain the hair braid. The cleaning brush can effectively remove the stains and rust on the surface of the hair braid, and then the medium is evenly applied through the sponge to improve the maintenance effect; the maintenance personnel control the cavity through the medium delivery rod to maintain the hair braid, which greatly reduces the safety risks of the maintenance personnel, and the medium delivery rod and the cavity are rotatably connected, which is easier to operate when used; the medium is stably input into the cavity through the medium delivery pump to prevent excessive overflow of the medium, reduce the use of the medium, and avoid environmental pollution.

[0035] Specifically, Figure 2 , 6 As shown, four guide wheels 1 are respectively arranged on the upper and lower parts of the cavity 2 .

[0036] Exemplarily, two guide wheels are disposed on the upper and lower sides of each semi-cylindrical cavity, and the two guide wheels on the same end form an angle of 90 degrees, which can better limit the sliding direction of the cavity during operation.

[0037] Specifically, Figure 5 As shown, the locking device 3 is fixed by a lock nut 6 .

[0038] Exemplarily, the two semi-cylindrical cavities are locked and fixed by a locking nut to ensure that the cavity wraps the hair braids tightly during operation, and at the same time, prevent the injected medium from leaking and causing environmental pollution.

[0039] Specifically, Figure 1 , 7 As shown, the medium conveying rod connection 7 is a cylindrical U-shaped slot, and the connecting ring 14 is embedded in the slot and fixed by a bolt to achieve a rotatable connection.

[0040] Specifically, Figure 1 As shown, the medium delivery pump 15 is a hydraulic pump.

[0041] Exemplarily, the engine oil or butter or a mixture of engine oil and butter is evenly mixed in advance and put into a hydraulic pump, and the hydraulic pump is turned on to smoothly transport the medium into the cavity for maintenance use.

[0042] Specifically, Figure 3 As shown, the sponge 13 in the cavity is detachably installed.

[0043] For example, after long-term use, the sponge in the cavity will cause wear and dirt, affecting the maintenance effect. It can be removed and replaced with a new sponge to ensure better adhesion of the medium and maintenance effect.

[0044] Specifically, the cleaning brush 12 is a wire brush.

[0045] Specifically, Figure 2 As shown, two cleaning brushes 12 are arranged in each of the semi-cylindrical cavities.

[0046] Exemplarily, two cleaning brushes are installed in the semi-cylindrical cavity, which can better remove stains and rust stains on the braids and achieve better maintenance effects.

[0047] Specifically, the medium outlet 11 is connected to the medium delivery hole 4 through a hose.

[0048] Embodiment 2:

[0049] In some embodiments, after arriving at the well site, first pour butter or engine oil or a mixture of butter and engine oil into the hydraulic pump, and use a hose to connect the hydraulic pump to the medium input port of the medium delivery rod; merge the two semi-cylindrical cavities, surround the middle of the cavity with a braid, tighten it with a locking nut, and then start the hydraulic pump. Under the action of pressure, the medium passes through the hose, the medium delivery rod, and the medium delivery port and enters the cleaning brush and sponge in the cavity; the staff holds the medium delivery rod and moves it up and down to control the movement of the cavity on the braid, cleans the oil stains on it, and maintains it.

[0050] The use of the above maintenance tools for maintenance greatly reduces the amount of lubricating oil used. The traditional method uses 0.5 kg of lubricating oil to maintain a braid, while the above maintenance tools only require 0.2 kg of lubricating oil or less to maintain the entire braid; and the time for maintaining a braid is reduced from 40 minutes to 30 minutes, saving maintenance time and increasing production efficiency. A certain oil field production area currently has 80 pumping wells, with a daily oil output of 1040.5 tons. The annual production affected by stopping wells for braid maintenance is: 1040.5 tons / 24 hours (hourly oil production) * 0.17 hours (quarterly production affected by braid maintenance) * 4 = 29.48 tons / year (annual production affected by braid maintenance). Based on 2,000 yuan per ton of oil, the annual income can be increased by 58,960 yuan.

[0051] It should be noted that the above-mentioned specific implementation methods can enable those skilled in the art to more fully understand the invention of the utility model, but do not limit the invention of the utility model in any way. Therefore, although this specification has described the invention of the utility model in detail with reference to the drawings and embodiments, those skilled in the art should understand that the invention of the utility model can still be modified or replaced by equivalents. In short, all technical solutions and improvements that do not deviate from the spirit and scope of the invention of the utility model and their improvements should be included in the protection scope of the patent of the invention of the utility model.
