DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] like Figure 1-Figure 8 As shown, an oilfield equipment cleaning device proposed in one embodiment of the present application includes:

[0030] A cleaning frame 1, on which two supporting rollers 2 are rotatably arranged, the cleaning frame 1 comprises a frame, and legs are arranged at both ends of the bottom of the frame, the two supporting rollers 2 are rotatably arranged on the frame, and the two supporting rollers 2 are used to place the oil pipe. When cleaning, the driving force is used to drive the two supporting rollers 2 to rotate synchronously in the same direction, so that the two supporting rollers 2 can not only support the oil pipe, but also drive the oil pipe to rotate;

[0031] A movable frame 3 is slidably arranged on the cleaning frame 1. The movable frame 3 is horizontally slidably arranged on the frame. An annular tube 4 surrounding two supporting rollers 2 is arranged on the movable frame 3 through a support rod. A plurality of first nozzles 5 distributed in an annular shape are arranged in an array on the inner side wall of the annular tube 4. The outer surface of the annular tube 4 is connected with a first water pipe 6. Preferably, the free end of the first water pipe 6 is connected with an external cleaning liquid pipeline. When the oil pipe is placed on the two supporting rollers 2, the annular tube 4 is coaxially arranged with the oil pipe. The cleaning liquid is transported to the annular tube 4 through the first water pipe 6, and then sprayed out through the plurality of first nozzles 5, so as to flush the outer surface of the oil pipe. The sliding movable frame 3 moves, so that the outer surface of the oil pipe is gradually cleaned.

[0032] The U-shaped frame 7 has two ends of its opening connected to the movable frame 3. A second water pipe 8 is provided at one end of the U-shaped frame 7 away from the cleaning frame 1. A disc 9 is connected to the end of the second water pipe 8 close to the movable frame 3. A plurality of second nozzles 10 distributed in an annular manner are connected to the outer surface array of the disc 9. Preferably, the free end of the second water pipe 8 is connected to an external cleaning liquid pipeline. When the oil pipe is placed on the two supporting rollers 2, the second water pipe 8 is coaxial with the oil pipe. At this time, the sliding movable frame 3 moves, and the second water pipe 8 is coaxially inserted in the oil pipe. The cleaning liquid is transported to the disc 9 through the second water pipe 8, and then sprayed out through a plurality of second nozzles 10, thereby flushing the inner wall of the oil pipe. As the movable frame 3 moves, the inner wall of the oil pipe is gradually cleaned. Step cleaning, the overall structure of the device, the second water pipe 8 and the annular pipe 4 are coaxially arranged with the oil pipe placed on the supporting roller 2, when the movable frame 3 moves, the annular pipe 4 is sleeved on the oil pipe, and the second water pipe 8 is inserted in the oil pipe, and the first nozzle 5 and the second nozzle 10 are used to flush the outer and inner walls of the oil pipe respectively, so that the inner and outer walls are cleaned at the same time, thereby improving the cleaning efficiency. At the same time, although the oil pipe is placed on two supporting rollers 2, the two supporting rollers 2 will drive the oil pipe to rotate when they rotate synchronously, so that the outer surface of the oil pipe can be fully flushed and cleaned. The movable frame 3 slides back and forth one round, which can not only clean the inner and outer walls of the oil pipe synchronously, but also clean them twice at the same time, which not only improves the cleaning efficiency, but also improves the cleaning effect.

[0033] like Figure 3 and Figure 5 As shown, in some embodiments, a sliding rod 11 and a screw rod 12 are provided on the cleaning frame 1. Preferably, the sliding rod 11 is fixedly provided on the cleaning frame 1, and the screw rod 12 rotates and penetrates the cleaning frame 1. One end of the movable frame 3 is slidably sleeved on the sliding rod 11, and the other end is threadedly sleeved on the screw rod 12. One end of the screw rod 12 is connected to a motor 13 provided on the cleaning frame 1. A first pulley assembly 14 is connected between the two supporting rollers 2, and a second pulley assembly 15 is connected between one of the supporting rollers 2 and the screw rod 12. When the motor 13 works, its output shaft drives the screw rod 12 to rotate. Under the action of the thread and the sliding limit of the sliding rod 11, the movable frame 3 is driven to move, so that the inner and outer walls of the oil pipe are gradually cleaned. At the same time, when the screw rod 12 rotates, the second pulley assembly 15 drives one of the supporting rollers 2 to rotate synchronously. At the same time, under the linkage of the first pulley assembly 14, the other supporting roller 2 is rotated synchronously. Under the synchronous and unidirectional rotation of the two supporting rollers 2, the oil pipe is driven to rotate.

[0034] like Figure 7As shown, in some embodiments, the outer surface of the supporting roller 2 is provided with a rubber sleeve 16, and the outer surface array of the rubber sleeve 16 is provided with a plurality of rubber strips 17 distributed in a ring shape. The rubber sleeve 16 and the rubber strips 17 are provided to increase the friction between the oil pipe and the supporting roller 2, so that the oil pipe can rotate stably, ensuring the cleaning effect of its outer wall.

[0035] like Figure 2 and Figure 6 As shown, in some embodiments, the cleaning frame 1 is arranged at an angle, and the two supporting rollers 2 are located at the end with a lower inclination and are provided with a limit plate 18. By arranging the cleaning frame 1 at an angle, the oil pipe is also in an inclined state after being placed, so that the cleaning liquid can be discharged from the oil pipe more conveniently when the inside is cleaned. The limit plate 18 is provided to limit the oil pipe to prevent it from axial movement under the stress of rotation.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, a water collecting frame 19 is provided at the bottom of the cleaning rack 1. Since oil stains are attached to the inner and outer walls of the oil pipe, when the cleaning liquid is flushed thereon, the cleaning liquid will also contain oil stains. The water collecting frame 19 is provided to collect the flushed cleaning liquid, which not only facilitates the subsequent cleaning of the cleaning liquid, but also prevents the cleaning liquid from overflowing onto the ground, thereby maintaining the cleanliness of the floor of the cleaning station. Preferably, a drain pipe is connected to the water collecting frame 19 to facilitate the discharge of the collected cleaning liquid.

[0037] like Figure 1 As shown, in some embodiments, water retaining covers 20 are provided on both opposite sides of the movable frame 3. When the outer wall of the oil pipe is flushed, the cleaning liquid flushes the oil pipe under pressure, causing part of the cleaning liquid to splash. The water retaining covers 20 are provided to prevent the cleaning liquid from splashing outside the cleaning frame 1, so that the cleaning liquid can be effectively collected.

[0038] like Figure 1 As shown, in some embodiments, the cleaning frame 1 is rotatably provided with two support rollers 21 at one end with a high inclination, and the U-shaped frame 7 is overlapped on the two support rollers 21. Since the oil pipe has a certain length, the second water pipe 8 and the U-shaped frame 7 have a certain length. The second water pipe 8 has a certain gravity after water passes through it. Through the provided support rollers 21, when the movable frame 3 moves, the U-shaped frame 7 overlaps with the two support rollers 21, and the support rollers 21 support the U-shaped frame 7 and the second water pipe 8, thereby ensuring that the second water pipe 8 and the oil pipe remain in a coaxial state, avoiding contact and friction between the second water pipe 8 and the inner wall of the oil pipe, thereby improving practicality.

[0039] like Figure 6 and Figure 8As shown, in some embodiments, a plurality of support rods 22 are arranged in an array on the outer surface of one end of the second water pipe 8 close to the disc 9, and a ball 23 is rollingly inserted at the free end of the support rod 22. Since the end of the second water pipe 8 close to the disc 9 is in a suspended state, and the cleaning liquid is sprayed from the second nozzle 10 to flush the inner wall of the oil pipe, there is water flushing stress. Under the action of the stress, the end of the second water pipe 8 close to the disc 9 will shake. Through the arranged support rod 22, the ball 23 will overlap with the inner wall of the oil pipe to support the second water pipe 8, so as to prevent the shaking of the second water pipe 8 and cause the second nozzle 10 to collide with the inner wall of the oil pipe. At the same time, the ball 23 rolls and overlaps with the inner wall of the oil pipe, which not only does not affect the normal movement of the second water pipe 8, but also does not affect the normal rotation of the oil pipe.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
