Description

Technical Field

[0001] This utility model relates to the field of stain removal technology for drill pipe surfaces, and particularly to a device for removing stains from the surface of oil drill pipes. Background Technology

[0002] A drill pipe is a threaded steel pipe used to connect the surface equipment of a drilling rig to the drilling equipment or bottom hole assembly located at the bottom of the well. The purpose of the drill pipe is to transport drilling mud to the drill bit and, together with the drill bit, raise, lower, or rotate the bottom hole assembly. Drill pipes can be reused multiple times during oil and gas extraction and refining processes.

[0003] In oil extraction, the main winch is used to slowly lift the drill pipe, align the follower frame guide rail with the mast track surface, pass it through the power head key sleeve, then lower the mast and fasten the sliding lug; finally, the mast is erected again and the drilling tools are installed so that drilling can be carried out. After the drill pipe is used, it needs to be cleaned so that it can be used again next time.

[0004] Current cleaning methods typically involve manual high-pressure water guns. This method often results in water splashing everywhere, and because it's a single-person operation, when the drill pipe needs to be rotated, it requires either cleaning the water gun or finding another worker for assistance. Therefore, a device for removing dirt from the surface of oil drill pipes is proposed. Utility Model Content

At the same time, the servo motor can drive the drill rod to roll. When the drill rod rotates, the high-pressure nozzle in the cleaning frame sprays the cleaning fluid onto the surface of the drill rod.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] Example 1

[0037] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a stain removal device for the surface of oil drill pipe, including a workbench 1, a support frame 2 fixedly connected to the upper surface of the workbench 1, and a chain plate conveyor belt 8 installed on the upper surface of the workbench 1. The feature is that: a rolling mechanism 3 is provided on the outer surface of the support frame 2, and a cleaning frame 6 is fixedly connected to the upper surface of the support frame 2.

[0038] The rolling mechanism 3 includes a rotating shaft 302 inserted inside the support frame 2, and a telescopic rod 304 fixedly connected to the worktable 1 and the surface of the right support frame 2. A spring 305 is sleeved on the outer surface of the telescopic rod 304. A concave seat 306 is fixedly connected to the end of the telescopic rod 304 away from the worktable 1 and the support frame 2. A rolling roller 307 is provided inside the concave seat 306 connected to the support frame 2. An arc-shaped cleaning plate 308 is hinged to the outer surface of the left support frame 2 through a support plate. A transmission sprocket 303 is installed at both ends of the rotating shaft 302 and the rolling roller 307, as well as inside the concave seat 306. A transmission chain 301 is connected to the outer surface of the transmission sprocket 303.

[0039] Specifically, a servo motor 7 is fixedly connected to the outer surface of the workbench 1 via a support base. The output end of the servo motor 7 is fixedly connected to one end of a rotating shaft 302 inserted inside the workbench 1. A high-pressure nozzle is installed on the inner wall of the cleaning frame 6. The high-pressure nozzle is connected to a cleaning fluid storage tank via a water pipe. A water pump is installed between the cleaning fluid storage tank and the water pipe. A cleaning cotton brush that can be replaced according to the drill rod specification is installed on the outer surface of the arc-shaped cleaning plate 308. A frosted pad that increases friction is installed on the outer surface of the rolling roller 307. The thickness of the cleaning cotton brush is five to eight centimeters. A limit rod is fixedly connected to the outer surface of the support frame 2. The limit rod is inserted into the interior of a concave seat 306 near the side of the support frame 2. There are eight to ten telescopic rods 304 on the support frame 2. A limit hole for the transmission chain 301 to pass through is opened inside the support frame 2.

[0040] Furthermore, when the drill rod contacts the mounting base 501 above the worktable 1, the concave seat 306 above the worktable 1 moves downward under the action of the spring 305, thereby ensuring that the tension between the transmission chain 301 and the transmission sprocket 303 can be adjusted according to the size of the drill rod, ensuring that the drill rod can be in close contact with the arc-shaped cleaning plate 308. At the same time, the servo motor 7 can drive the drill rod to roll. When the drill rod rotates, the high-pressure nozzle in the cleaning frame sprays the cleaning fluid onto the surface of the drill rod. The impact force of the cleaning fluid and the arc-shaped cleaning plate 308 can be used to clean the dirt on the surface of the drill rod at the same time, improving the portability of drill rod cleaning.

[0041] Example 2

[0042] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. A push plate 4 is provided on the upper surface of the chain plate conveyor belt 8, and an adjustment mechanism 5 is provided between the push plate 4 and the chain plate conveyor belt 8.

[0043] The adjustment mechanism 5 includes a mounting base 501 fixedly installed on the upper surface of the chain plate conveyor belt 8, and a locking block 502 fixedly connected to the lower surface of the push plate 4. A pressing rod 503 is inserted inside the mounting base 501, and a locking groove 504 is opened inside the mounting base 501 to engage with the mounting base 501.

[0044] Specifically, the adjustment mechanism 5 also includes a crossbar 505 fixedly connected to the locking block 502 and a pressing hole 506 opened inside the mounting base 501. Compression springs 507 are provided on the outer surface of the crossbar 505 and inside the pressing hole 506. The locking block 502 is connected to a locking block 508 that engages with the mounting base 501 through the compression spring 507. The crossbar 505 is inserted inside the locking block 508. The pressing rod 503 passes through the pressing hole 506 and abuts against the locking block 508. An arc-shaped groove is opened on the upper surface of the mounting base 501. Rollers are provided on the inner wall of the arc-shaped groove. The distance between the mounting bases 501 is 20 to 30 centimeters.

[0045] Furthermore, the drill rod is placed above the chain conveyor belt 8. By pressing the pressing rod 503 inside the mounting base 501, the pressing rod 503 squeezes the locking block 508. When the locking block 508 separates from the mounting base 501, the push plate 4 can be lifted upward. Then, the position of the push plate 4 can be adjusted according to the actual length of the drill rod to ensure that the device can stably push the drill rod.

[0046] Working principle: During oil and gas extraction, when cleaning the drill rod after use is required, the drill rod is placed above the chain conveyor belt 8. If the drill rod is too long or too short, the pressing rod 503 inside the mounting base 501 is pressed, which squeezes the locking block 508. When the locking block 508 separates from the mounting base 501, the push plate 4 can be lifted upwards. The position of the push plate 4 can then be adjusted according to the actual length of the drill rod to ensure that the device can stably push the drill rod. When the drill rod contacts the mounting base 501 above the worktable 1, it can squeeze the rolling roller 307. When 307 moves to one side, the concave seat 306 above the worktable 1 moves downward under the action of the spring 305, thereby ensuring that the tension between the transmission chain 301 and the transmission sprocket 303 can be adjusted according to the size of the drill rod, ensuring that the drill rod can be in close contact with the arc-shaped cleaning plate 308. At the same time, the servo motor 7 can drive the drill rod to roll. When the drill rod rotates, the high-pressure nozzle in the cleaning frame sprays the cleaning fluid onto the surface of the drill rod. The impact force of the cleaning fluid and the arc-shaped cleaning plate 308 can be used to clean the dirt on the surface of the drill rod, improving the portability of drill rod cleaning.
