Description

Technical Field

[0001] This utility model relates to the field of drill pipe processing equipment, specifically to a multi-station automatic reversing cleaning device for drill pipes. Background Technology

[0002] Drill pipe is a steel pipe with threads at the tail, used to connect the drilling rig's surface equipment 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.

[0003] After use, drill pipes need to be cleaned. The upper part of the threaded section of the drill pipe has a prismatic protrusion. Existing cleaning equipment washes one side of the drill pipe by placing it under the flushing equipment. After one side is washed, it is flipped over to wash the other side. The existing cleaning equipment is inefficient. Therefore, a multi-station automatic reversing cleaning equipment for drill pipes is needed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station automatic drill pipe reversing and cleaning device that can simultaneously reversing and cleaning multiple drill pipes without requiring them to be flipped during the cleaning process, thereby improving the cleaning efficiency and effect of the drill pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station automatic drill rod reversing cleaning device, comprising a drive unit and a transmission box, wherein the transmission box has multiple output shafts, and each output shaft of the transmission box is fixedly connected to a positioning seat, wherein the positioning seat is provided with a positioning groove and a drainage groove, and drill rod limiting components and flushing components are respectively provided on both sides of the transmission box, wherein the drill rod limiting components include a limiting cylinder and a limiting plate, and the flushing components include a lifting mechanism and a seat plate, wherein multiple sets of nozzles are provided on the seat plate.

[0006] Furthermore, the driving device is specifically a motor, the transmission box is specifically a gearbox, and the output end of the driving device is fixedly connected to the input end of the transmission box.

[0007] Furthermore, there are multiple drainage channels, and these drainage channels are arranged in a circular array along the positioning channel, with the drainage channels connected to the positioning channel.

[0008] Furthermore, the limiting plate is fixedly connected to the piston rod of the limiting cylinder, and the limiting plate is offset from the positioning seat.

[0009] Furthermore, the limiting plate is provided with an inclined surface.

[0010] Furthermore, the lifting mechanism is specifically a linear module, the base plate is fixedly connected to the moving platform of the lifting mechanism, and the nozzle is fixedly connected to the base plate.

[0011] Furthermore, the nozzle is C-shaped, and the nozzle is correspondingly arranged with the positioning seat, with the spray holes of the nozzle distributed on its inner sidewall.

[0012] The beneficial effects of this utility model are as follows: by setting up a drive frame, transmission box and positioning seat, multiple drill rods can be reversed at the same time. The flushing component with liftable cleaning function can be cleaned while the drill rod is being reversed, without the need to flip it over during the cleaning process, thus improving the cleaning efficiency and cleaning effect of the drill rod.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] Example:

[0021] refer to Figures 1-4 The multi-station automatic drill pipe reversing cleaning device shown includes a drive unit 1 and a transmission box 2. The transmission box 2 has multiple output shafts, and each output shaft of the transmission box 2 is fixedly connected to a positioning seat 3. The positioning seat 3 is provided with a positioning groove 301 and a drainage groove 302. Drill pipe limiting components and flushing components are respectively provided on both sides of the transmission box 2. The drill pipe limiting component includes a limiting cylinder 401 and a limiting plate 402. The flushing component includes a lifting mechanism 501 and a seat plate 502. Multiple sets of nozzles 503 are provided on the seat plate 502.

[0022] The drive unit 1 is specifically a motor, and the transmission box 2 is specifically a gearbox. The drive unit 1 and the transmission box 2 drive multiple positioning seats 3 to rotate. Multiple drainage grooves 302 are provided on each positioning seat to drain the water flowing into the positioning groove 301 and prevent water accumulation in the positioning seat 3 during the cleaning process.

[0023] The extension and retraction of the piston rod of the limiting cylinder 401 can drive the limiting plate 402 to perform translational movement, thereby limiting and repositioning the drill rod. The limiting plate 402 is offset from the positioning seat 3 to avoid interference when the limiting plate 402 moves. The limiting plate 402 is provided with an inclined surface to facilitate the drainage of water.

[0024] The lifting mechanism 501 is specifically a linear module. The lifting mechanism 501 is used to drive the base plate 502 to rise and fall, thereby enabling the nozzle 502 to rinse the drill rod from top to bottom. The nozzle 503 is C-shaped and is set correspondingly to the positioning base 3. The water spray holes of the nozzle 503 are distributed on its inner sidewall. The C-shaped structure of the nozzle 503 can better clean the sidewall of the drill rod.

[0025] The working principle of this utility model is as follows: (Refer to...) Figure 5 During the cleaning of the drill rod, the prism section of the drill rod is placed in the positioning seat 3 along the positioning groove 301. After all the drill rods are placed, the piston rod of the limiting cylinder 401 extends, and the limiting plate 402 moves to the top of the prism section of the drill rod to limit it, preventing the positioning seat 3 from rotating together with the drill rod without longitudinal displacement. During cleaning, the positioning seat 3 is driven to rotate by the driving device 1 and the transmission box 2. During the rotation of the drill rod, the seat plate 502 is driven to rise and fall by the lifting mechanism 501, and water is sprayed by the nozzle 503 to rinse the continuously rotating drill rod.

[0026] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
