Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the protection scope of the present invention.

[0027] See also Figure 1 as well as Figure 2 As shown, this embodiment discloses a rust removal device for a drill pipe 101 used for oil exploration drilling work, comprising a support assembly, a driving device and a rust removal device, wherein the support assembly is used to support the drill pipe 101 to be rusted; the driving device is connected to the support assembly, and the driving device is used to drive the drill pipe 101 to rotate; the rust removal device is located below the drill pipe 101, and the rust removal device is used to be slidably installed on the support assembly through the driving device;

[0028] Among them, a dust cover 102 is provided on the support component, and the dust cover 102 has a slide groove 103 that communicates with the inside of the dust cover 102, and the rust removal device is used to slide with the slide groove 103 after passing through the slide groove 103; two dust-proof components are provided on the dust cover 102, and the dust-proof component is connected with the rust removal device. The dust-proof component includes a mounting rod 104, a dust-proof net 105, a roller 106 and a mounting cover 107, and the mounting cover 107 is arranged above the dust cover 102, and the mounting rod 104 is installed on the rust removal device, and the roller 106 is rotatably installed inside the mounting cover 107, one end of the dust-proof net 105 is connected to the roller 106 and is used to be wound on the roller 106, and the other end is fixedly connected to the mounting rod 104, and a clockwork spring is provided on the roller 106, and one end of the clockwork spring is connected to the roller 106, and the other end is connected to the mounting cover 107;

[0029] The utility model mainly comprises a supporting assembly, a driving device and a rust removing device. In actual use, the staff first installs the drill rod 101 that needs to be rust removed on the supporting assembly, and then starts the driving device. After the driving device is started, the drill rod 101 is driven to rotate. At the same time, the driving device controls the rust removing device to slide on the supporting device. The rust removing device removes rust stains on the surface of the drill rod 101 during the sliding process. In this process, when the rust removing device slides, the dustproof net 105 on one side of the rust removing device is pulled out, and the dustproof net 105 on the other side is rolled up, and the rust stains fall on the dustproof net 105. When the dustproof net 105 is rolled up, the rust stains are collected together. After the rust removal is completed, the dustproof net 105 is completely removed, cleaned, and reinstalled for reuse. The advantage of such a setting is that the rust stains can be collected, which is convenient for the staff to clean the equipment.

[0030] In some embodiments, the support assembly is used to be installed on the base 108; in actual use, the main function of the base 108 is to provide support for the support assembly and the rust removal assembly.

[0031] In some embodiments, there are two support assemblies, which are symmetrically arranged on the base 108. The support assemblies include a support table 109, a support frame 110 and a three-jaw chuck 111. The support table 109 is installed on the base 108, the support frame 110 is installed on the support table 109, and the three-jaw chuck 111 is rotatably installed on the support frame 110. The drill rod 101 is used to be installed on the three-jaw chuck 111, and the three-jaw chuck 111 is connected to the driving device.

[0032] During actual use, the driving device drives the three-jaw chuck 111 to rotate and then drives the drill rod 101 fixedly clamped on the two three-jaw chucks 111 to rotate. At the same time, the driving device drives the rust removal component to remove rust from the drill rod 101 while the drill rod 101 rotates.

[0033] In some embodiments, the driving device includes a motor 112 and a transmission mechanism. The motor 112 is mounted on the base 108 , and the motor 112 is connected to the three-jaw chuck 111 through the transmission mechanism.

[0034] In actual use, the motor 112 rotates to drive the three-jaw chuck 111 to rotate through the transmission mechanism.

[0035] In some embodiments, the transmission mechanism includes a driving sprocket, a driven sprocket 113 and a chain. The driving sprocket is fixedly mounted on the output shaft of the motor 112 , the driven sprocket 113 is fixedly mounted on the three-jaw chuck 111 , and the chain is mounted on the driving sprocket and the driven sprocket 113 .

[0036] In actual use, the motor 112 rotates to drive the driving sprocket to rotate, and the driven sprocket 113 rotates along with the driving gear due to the engagement of the chain. Since the driven sprocket 113 is fixedly mounted on the three-jaw chuck 111, the motor 112 rotates to drive the three-jaw chuck 111 to rotate together.

[0037] In some embodiments, the output shaft of the motor 112 is also connected to a ball screw 117, the other end of the ball screw 117 is rotatably connected to a support platform 109 away from the motor 112, and a screw nut is fixedly installed on the rust removal device, and the ball screw 117 and the screw nut cooperate with each other.

[0038] During actual use, after the motor 112 rotates, it will also synchronously control the rotation of the ball screw. Since the screw nut and the ball screw cooperate with each other, the rotation of the ball screw will drive the rust removal device fixedly connected to the screw nut to slide on the base 108. The forward and reverse rotation of the motor 112 controls the rust removal device to perform reciprocating motion on the base 108. During the sliding process, the rust removal device removes rust from the drill rod 101. The advantage of this arrangement is that the drill rod 101 can be derusted in all directions, thereby ensuring the rust removal quality of the drill rod 101.

[0039] In some embodiments, the rust removal device includes a laser generator 114, a moving seat and a laser rust removal gun 115. The screw nut is fixedly mounted on the moving seat. The moving seat is slidably matched with the base 108. The laser generator 114 is mounted on the moving seat. The laser rust removal gun 115 is located directly below the drill rod 101. The laser rust removal gun 115 is connected to the laser generator 114. The laser generator 114 is used to remove rust from the drill rod 101 by emitting a laser through the laser rust removal gun 115. The mounting rod 104 is mounted on the outer surface of the laser generator 114.

[0040] In actual use, the laser rust removal gun 115 is located directly below the drill rod 101, and the laser generator 114 emits laser light through the laser rust removal gun 115 to clean the rust stains on the drill rod 101;

[0041] It should be noted that, in this embodiment, the laser generator 114 and the laser rust removal gun 115 are a complete set of laser rust removal devices in the prior art. This embodiment only installs the laser rust removal device as a whole on the movable seat, and does not involve improvements to the overall structure of the laser rust removal device, which will not be described one by one here.

[0042] In some embodiments, the mobile seat is slidably matched with the base 108 via a sliding assembly.

[0043] In actual use, providing a sliding component can make the sliding between the moving seat and the base 108 smoother.

[0044] In some embodiments, the sliding assembly includes a sliding rail disposed on the base 108 and a sliding recess disposed at the bottom of the moving seat, and the sliding rail and the sliding recess are slidably matched.

[0045] In actual use, the purpose of providing the slide rail and the slide recess is to limit the sliding of the moving seat, so that the sliding of the moving seat is more stable.

[0046] In some embodiments, a vacuum cleaner 116 is installed on the side wall of the laser generator 114, and the vacuum cleaner 116 is used to absorb rust stains.

[0047] In actual use, in order to save the frequency of replacing the dust net 105, an interception cover is set on the outer wall of the laser generator 114. The interception cover is a funnel-shaped structure. The small end of the interception cover is connected to the laser generator 114. A dust suction port is provided under the interception cover, and the dust suction port is connected to the vacuum cleaner 116. The vacuum cleaner 116 is set to collect rust stains on the dust net 105 to improve work efficiency.
