Description

Technical Field

[0001] This utility model relates to the field of well site equipment technology, specifically a grounding electrode removal kit. Background Technology

[0002] Currently, to improve the safety of personnel and equipment operation, the ground insulation resistance of mobile steam injection boiler equipment and facilities in oilfields should be less than 4Ω, and the grounding electrode must have sufficient burial depth to meet this standard. Removing the grounding electrode is difficult, consuming a lot of manpower and time, and affecting the smooth operation of production. Furthermore, mobile steam injection boilers are frequently relocated, with approximately 13-15 grounding electrodes to be installed and removed for each boiler each time, resulting in high labor intensity for employees and extended transportation time. After standardizing the integration of grounding electrodes for mobile steam injection boiler equipment and prefabricated houses: the grounding electrode is 100cm long, 20mm thick, with a pointed bottom and an 80mm diameter, 25mm thick iron disc at the top, connected to the grounding electrode via threads. The grounding electrode is driven to the required depth by hammering the iron disc. After connection to the equipment, the ground resistance is measured to be less than 4Ω. When removing the grounding electrode, it is first rotated with pipe wrenches, then vibrated around with a sledgehammer, and this process is repeated multiple times before removal, taking approximately 20 minutes to remove one electrode. The mobile boiler has 13 or 15 grounding electrodes. Each time it is moved, removing the grounding electrodes takes 4 to 5 hours, which affects the efficiency of the overall equipment relocation. There are many existing technologies for addressing the problem of removing grounding electrodes.

[0003] Announcement No. CN213093528U discloses a grounding electrode pulling device, including a grounding rod body, a support, a rotating seat, a worm gear, a lifting column, and a connecting rod. The worm gear meshes with a worm wheel provided on the outer wall of the rotating seat. The lifting column is connected to the rotating seat through a first external thread and a first threaded hole. The grounding rod body is connected to the connecting rod. The grounding electrode is pulled out through the mutual cooperation of the meshing of the worm gear and the worm wheel, the threaded connection between the lifting column and the rotating seat, and the connection between the grounding rod body and the connecting rod.

[0004] This existing technology has a diameter limitation and cannot accommodate grounding electrodes of various sizes.

[0005] Announcement No. CN215645057U discloses a temporary grounding device for petrochemical applications, comprising a support, a grounding electrode, and a soil cleaning device. The support includes a hollow telescopic rod with outriggers. The soil cleaning device includes a sleeve, fixing bolts, and a serrated blade. The sleeve is fixed to the lower end of the telescopic rod, and the sleeve wall has an arc-shaped slot into which the serrated blade is inserted. Nuts are fixed to both ends of the serrated blade via spring frames. The lower end of the grounding electrode passes through the telescopic rod and the sleeve. During the removal of the grounding electrode, the soil attached to its outer wall is scraped off by the serrated blade for future use. Simultaneously, the springs in the spring frame provide cushioning for the serrated blade, preventing it from scratching the grounding electrode.

[0006] The existing technology has a complex structure and high manufacturing cost.

[0007] Publication No. CN115483550A discloses a novel grounding lead device. When the grounding rod needs to be replaced, the user holds the rubber sleeve and lifts the pressure rod. The pressure rod, through the connecting arm and connecting strip, presses down on the sleeve. Because the tooth profile of the toothed rod is a downward-sloping helical tooth, the limiting tooth plate matches the tooth profile of the toothed rod. Therefore, the limiting tooth plate can move downward relative to the toothed rod, causing the sleeve to move downward along the toothed rod. Pressing down on the pressure rod causes the limiting tooth plate to lock the toothed rod and lift it up, prying the grounding rod upward. By repeatedly lifting and pressing the pressure rod, the grounding rod can be pried out for replacement. The threaded post can be removed by external rotation, and the rectangular pin can be pulled out. The pressure rod can be removed and stored, thus avoiding the pressure rod occupying space when the grounding rod does not need to be replaced.

[0008] The existing technology has limitations in aperture, cannot adapt to grounding electrodes of various sizes, has a reset time during operation, and the output force is discontinuous, which is relatively time-consuming.

[0009] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0038] Example 1:

[0039] Please see Figures 1 to 3 The present invention provides a grounding electrode removal kit, which includes a grounding electrode removal device and a grounding electrode.

[0040] The grounding electrode removal device includes a removal body 1 and a base 3, and the removal body 1 and the base 3 are connected by a bracket 2.

[0041] The lifting body 1 includes a housing 1.1. A first axle and a second axle are horizontally rotatably mounted through the housing 1.1. The first axle is connected to a rotating handle 1.2 outside the housing 1.1. A small gear 1.6 is provided inside the first axle of the housing 1.1. A large gear 1.3 is provided inside the second axle of the housing 1.1. The small gear 1.6 meshes with the large gear 1.3. A rope winding disc 1.7 is provided inside the second axle of the housing 1.1. The large gear 1.3 and the rope winding disc 1.7 are separated by a bushing. A steel wire rope 1.4 is fixedly connected to the rope winding disc 1.7. A hook 1.5 is fixedly mounted on the movable end of the steel wire rope 1.4.

[0042] The grounding electrode 4 includes a nail rod with an iron disc at the upper end. The connecting plate 5 is fixedly welded to the end of the nail rod of the grounding electrode 4 near the iron disc. The connecting plate 5 has a connecting hole that matches the hook 1.5.

[0043] The first and second wheel shafts are rotatably connected to the housing 1.1 via copper bushings or bearings, and the first and second wheel shafts are positioned by setting nuts at both ends of the first and second wheel shafts.

[0044] Among them, the pinion with 1.6 teeth has fewer teeth than the gear with 1.3 teeth.

[0045] Among them, wire rope 1.4 plays the role of force transmission. Wire rope 1.4 can also be replaced with other high-strength ropes, such as high-strength nylon rope.

[0046] The hook 1.5 is connected to the wire rope 1.4 at one end and hooked to the grounding electrode at the other end, serving as a medium for connecting the wire rope 1.4 and the grounding electrode 4.

[0047] When the lifting body 1 is working, the rotating handle 1.2 drives the small gear 1.6 to rotate, and the small gear 1.6 drives the large gear 1.3 to rotate. The large gear 1.3 drives the steel wire rope 1.4 to rotate and bear the tension.

[0048] In use, the hook 1.5 on the device hooks onto the connecting hole on the connecting plate 5 at the top of the grounding electrode 4. In special cases, the wire rope 1.4 is wrapped around the connecting plate 5 of the grounding electrode 4 once, and then secured with the hook 1.5. Rotating the handle 1.2 causes the wire rope 1.4 to move through the meshing of the large gear 1.3 and the small gear 1.6. Rotating the handle 1.2 with even force tightens the wire rope 1.4, while maintaining a stable force to avoid breaking it. The wire rope 1.4 is rotated and retracted into the winding reel 1.7, slowly removing the grounding electrode 4. Alternatively, hooking the grounding electrode with the hook 1.5 and rotating the handle 1.2 drives the gear to tighten the transmission rope, causing the hook 1.5 to move upwards, slowly removing the grounding electrode 4 from the ground, reducing manpower and improving work efficiency.

[0049] This utility model has a simple and lightweight structure, can be operated by one person, and can remove one grounding electrode in a maximum of 5 minutes, which is 15 minutes faster than the existing well site grounding electrode removal scheme. Removing 13 grounding electrodes only takes about 60 minutes, which reduces the labor intensity of employees, shortens the time for relocation and connection work, and improves work efficiency.

[0050] Example 2:

[0051] Based on Example 1, in this example, two connecting holes are provided on the connecting plate 5. When the hook 1.5 is damaged, the hook 1.5 is removed and the wire rope 1.4 is wound and fixed multiple times through the two connecting holes, so that the wire rope 1.4 and the connecting plate 5 have a large contact area, which facilitates hookless pulling.

[0052] In this embodiment, the housing 1.1 has a rope passage notch on its lower end face, the base 3 has a central opening, the rope passage notch is within the projection of the central opening of the base 3, the diameter of the iron disc is smaller than the central opening of the base 3, and the length of the bracket 2 is greater than the length of the grounding electrode, so that the lifting body 1 can be placed directly above the grounding electrode 4, improving the force transmission efficiency and further accelerating the speed of lifting the grounding electrode 4.
