Description

Technical Field

[0001] This utility model relates to the field of oil pumping machine technology, specifically a device for maintaining hair braids without the need for climbing. Background Technology

[0002] The braided rod is a key component connecting the polished rod and the suspension cable of the pumping unit, and it requires maintenance quarterly. Maintenance involves checking lubrication, wear, and broken wires, ensuring there are no broken strands, no rust, and sufficient lubrication to ensure even stress distribution. Because it involves working at height, each operation requires work permits and approvals, significantly increasing well downtime and impacting well production. Furthermore, working at height carries the risk of falls. Since frequent maintenance at height is inefficient and risky, achieving automated lubrication and maintenance of the braided rod without the need for climbing is crucial for improving operational safety and maintenance efficiency.

[0003] Announcement No. CN205778760U discloses a lubrication device for the braid of an oil pumping unit, comprising: an oil storage tank and an oil delivery pipe; the oil storage tank is a cylindrical body with a cavity, the oil storage tank is fixed to the burner head of the oil pumping unit and located above the braid of the oil pumping unit, the top of the oil storage tank is provided with an oil filling hole, and the cavity of the oil storage tank is connected to the outside through the oil filling hole; one end of the oil delivery pipe is located inside the braid of the oil pumping unit, and the other end is connected to the cavity of the oil storage tank.

[0004] The existing oil tank is large and weighs over 5 kg, making it impossible to replace on the ground. Each replacement requires climbing onto the donkey's head for high-altitude work, which requires approval and invoicing procedures. When the braid bears the load, the strands are tightly connected, making it difficult to insert the oil injection needle. The strong magnetic fixing method is not very secure.

[0005] Announcement No. CN202338756U discloses a pneumatic braid maintenance device, including a pressure vessel and an air pump. The upper part of the pressure vessel is provided with an air inlet, which is connected to the air pump through a pipeline. A pressure gauge is provided at the air inlet. The bottom of the pressure vessel is provided with an oil outlet, which is connected to one end of an oil pipeline through a valve.

[0006] The existing technology suffers from drawbacks: the centralizing device is too large, installation is difficult, and a two-part plug-in connection is required, resulting in poor sealing. The lubrication time is short, and lubricant has difficulty penetrating the rope strands. Each maintenance cycle involves long downtime, reducing well start-up rate and impacting normal well production.

[0007] Announcement No. CN216280579U discloses a lubrication auxiliary device for a pumping unit's braid, comprising a trolley, an oil drum, an oil pump, a delivery pipe, a lifting mechanism, and an oiling mechanism; the oil drum is fixedly connected to the trolley; the oil pump is fixedly connected to the top of the trolley at the end away from the trolley's push rod; the input end of the oil pump is connected to the oil drum via a pipe, and the output end of the oil pump is connected to the oiling mechanism via an oil delivery pipe; the lifting mechanism is connected to the oiling mechanism; a first electric telescopic rod can raise the oiling mechanism to the top of the braid.

[0008] The existing technology requires operators to hold the electric telescopic pole for a long time, which is physically demanding and will affect the maintenance effect.

[0009] The existing technologies described above have drawbacks in practical use, including poor lubrication, loose mounting brackets, and prolonged well shutdowns requiring access to heights. To address these issues, a new, height-free braid maintenance device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] Please see Figures 1 to 4 This utility model provides a no-climbing braid maintenance device, including an adjustable fixing frame 2, an oil reservoir fixing bracket 4, and an oil reservoir 11. The adjustable fixing frame 2 is U-shaped and includes a side plate, a horizontal plate, and two side plates. The side plate and the two side plates are provided with opposing tightening screws 3 for clamping onto the donkey head 1. The oil reservoir fixing bracket 4 is connected to the horizontal plate away from the side plate. The oil reservoir 11 is locked in the oil reservoir fixing bracket 4. The bottom of the oil reservoir 11 is provided with an oil dripping pipe 15 that extends out of the oil reservoir fixing bracket 4. The oil dripping pipe 15 is used to drip oil onto the braid 6. The upper end of the oil reservoir 11 is provided with a lifting ring 10, which makes it easy to use a hook to remove the oil reservoir 11 without climbing and replenish the lubricating oil.

[0038] Furthermore, the adjustable fixing bracket 2 is used to install the oil reservoir bracket 4. The horizontal plate of the adjustable fixing bracket 2 is provided with two collinear elongated slots 5, and an oil reservoir bracket 4 is provided on each elongated slot 5, so that the two oil reservoir brackets 4 correspond to the two braids 6 respectively. The upper end of the oil reservoir bracket 4 is provided with a suspension nose 7, and the suspension nose 7 is connected to the elongated slot by bolts and nuts. Through the elongated slots 5 and the suspension nose 7, the position of the oil reservoir fixing bracket 4 can be adjusted according to the different widths of the braids 6, so that the oil reservoir 11 is always aligned with the center position of the braids 6, in order to adapt to different specifications of oil pumping unit models.

[0039] Specifically, the horizontal plate of the adjustable fixing frame 2 is 400mm long, 60mm wide, and 6mm thick, and is made of 25# steel. The length of one side plate and the second side plate is 70mm. Two set screws 3 are designed on each of the one side plate and the second side plate. The adjustable fixing frame 2 is fixed to the upper part of the donkey head 1 by the set screws 3 on both sides.

[0040] Furthermore, the function of the oil reservoir fixing bracket 4 is to provide stable support for the oil reservoir 11. The body of the oil reservoir fixing bracket 4 is a conical sleeve 8 with openings at both the top and bottom. The upper end of the conical sleeve 8 is provided with a hanging nose 7 and a slot. The outer wall of the oil reservoir 11 is conical and matches the inner wall of the conical sleeve 8. The upper outer wall of the oil reservoir 11 is provided with a locking block. The slot and locking block can position the oil reservoir 11 so that the drip pipe is aligned with the braid 6 after the oil reservoir 11 is installed in place.

[0041] Specifically, the slot is a V-shaped notch 9, and the block is a V-shaped protrusion 14, which realizes positioning and limiting functions, ensures accurate installation, and facilitates the quick removal and installation of the oil reservoir.

[0042] Specifically, the tapered sleeve 8 is made of 1mm stainless steel plate and has an overall tapered shape of φ100*φ60*100, ensuring accurate positioning and quick installation during operation.

[0043] Specifically, the suspension nose 7 is located on the upper inner side of the conical sleeve 8, and is designed with a φ6mm hole. It is made of 1mm stainless steel plate and is connected to the conical sleeve 8 by welding. It is connected to the adjustable fixing bracket 2 by bolts. The suspension nose 7 is provided with a bend angle so that the bolt head will not obstruct the oil reservoir 11 from falling into the oil reservoir fixing bracket 4.

[0044] Specifically, the V-shaped notch 9 has a width and height of 25mm*30mm, and the V-shaped boss has a width and height of 25mm*30mm and a thickness of 5mm. The V-shaped notch 9 and the V-shaped boss 14 are precisely matched to play a positioning role, ensuring that the oil dripping pipe 15 of the oil reservoir 11 is always in the center of the braid, simplifying the operation process.

[0045] Specifically, the oil reservoir fixing bracket 4 is designed as a cone structure, which makes it easy to quickly and smoothly put in and take out the oil reservoir 11, reducing the difficulty of operation.

[0046] Furthermore, the function of the oil reservoir 11 is to store lubricating oil to provide lubrication for the braid 6. The oil reservoir 11 includes a reservoir body, which is a conical closed box. The upper end face of the reservoir body is provided with a lifting ring 10, a breather tube 12, and an oil filling port 13. The lower end face of the reservoir body is provided with an oil drain port 16, which is connected to an oil dripping pipe 15. The upper end of the outer wall of the reservoir body is provided with a V-shaped protrusion 14 for engaging with a V-shaped notch 9, so that the reservoir body is installed in the oil reservoir fixing bracket 4.

[0047] Specifically, the kettle body is made of 1mm stainless steel plate and has a tapered shape of φ95mm*φ55mm*100mm. It matches the tapered shape of the tapered sleeve 8 to achieve quick installation and removal. When filled with lubricating oil, the overall weight is about 2kg, which makes it easy to lift to a high place with special tools, such as using a rod hook for suspension.

[0048] Specifically, the lifting ring 10 is made of φ4mm stainless steel and is welded to the body of the oil container. The lifting ring 10 facilitates the use of a rod hook inserted into the ring for suspension and movement, enabling the quick removal and placement of the oil container 11.

[0049] Specifically, the oil filling port 13 has a diameter of φ10mm, is welded to the body of the container, and has a cap at the head to prevent rainwater from entering the container. The oil filling port 13 is provided to facilitate the replenishment of lubricating oil.

[0050] Specifically, the breathing tube 12 has a diameter of φ4mm and is welded to the body of the oil reservoir, so that the cavity of the oil reservoir 11 is connected to the outside world, allowing the lubricating oil to drip continuously onto the braid 6 under the action of gravity. The breathing tube is U-shaped with the opening facing downward, which can prevent rainwater from entering the oil reservoir 11.

[0051] Specifically, the oil dripping pipe 15 is a φ4mm pipe, which is connected to the oil drain port 16 by an expansion joint and is made of brass material. It can be bent at an angle while maintaining a certain rigidity to ensure that it will not shift due to wind or other factors. The oil dripping pipe 15 allows lubricating oil to drip continuously onto the braid 6.

[0052] Furthermore, the suspended nose 7 and the V-shaped notch 9 are arranged opposite each other, the lifting ring 10, the breathing tube 12, and the filling port 13 are arranged in a straight line, the lifting ring 10 is located on the outer ring, and the V-shaped boss is located on the line of symmetry of the straight line, so that the device will not have assembly interference.
