Description

Technical Field

[0002] With the widespread use of GIL (gas-insulated metal-enclosed transmission line), the shortcomings of GIL transmission lines have also been exposed. Although GIL transmission lines have large transmission capacity, high safety, and space saving, tiny particles or dust layers inside can affect the safe operation of the equipment and make fault location difficult. At present, when installing GIL, people enter the GIL pipeline to clean the sharp corners, burrs, and dust layers inside the pipeline. Faced with a series of factors such as small space, limited vision, human limitations, and substandard ambient air particle size, after the GIL is installed, equipment failures caused by tiny particles or dust layers gradually increase, and it is becoming increasingly difficult to meet the existing line operation and maintenance requirements. Under different pipeline diameters, even if manual cleaning is used, there are many inconveniences due to the different body shapes of workers. The dust layer of particles floating after cleaning will also affect the health of workers.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] Example 1 Reference Figures 1 to 3 The present embodiment provides a pipe polishing device adapted to different pipe diameters, including: a support mechanism 100 for stably setting the entire pipe polishing device on the pipe to be processed, a matching claw 105 is also provided opposite to the stabilizing claw 101 for matching with each other, the stabilizing claw 101 and the matching claw 105 are connected by a main shaft 103, and the stabilizing claw 101 and the matching claw 105 are respectively fixedly arranged on both sides of the pipe to be processed, so as to ensure that the entire pipe polishing device is stable and will not loosen and fall.

[0032] The main control assembly 102 is fixedly installed on one side of the stabilizing claw 101, and the pipe grinding device can be operated through the main control assembly 102. The adjustment mechanism 200 is sleeved on the main shaft 103, and the center of the adjustment mechanism 200 is the rotating assembly 201. The rotating assembly 201 and the main control assembly 102 are electrically connected. The rotating assembly 201 can be directly operated by the main control assembly 102, so that the rotating assembly 201 can translate and rotate along the main shaft 103.

[0033] The cleaning ring 202 is fixedly arranged on the outside of the rotating assembly 201 and is fixedly connected to the rotating assembly 201. When the rotating assembly 201 moves, the cleaning ring 202 will also move with it. An adjustment shaft 202a is rotatably embedded in the outer wall of the cleaning ring 202, and a rotating scraper 205 is fixedly arranged on the outside of the adjustment shaft 202a. In the default state, the adjustment mechanism 200 is stored on one side of the stabilizing claw 101. When the entire device is started, the adjustment mechanism 200 rotates clockwise while moving toward the other side of the pipeline.

[0034] Since there is no force restricting the adjusting shaft 202a, the adjusting shaft 202a will rotate clockwise under the centrifugal force generated by the high-speed rotation of the adjusting mechanism 200. A rotating scraper 205 is provided on the outside of the adjusting shaft 202a, and the rotating scraper 205 will rotate and unfold with the adjusting shaft 202a. The unfolding range of the rotating scraper 205 will be determined according to the diameter of the pipe. The larger the diameter, the greater the unfolding degree of the rotating scraper 205. Finally, the rotating scraper 205 will still fit the inner wall of the pipe, and use the matching teeth 205a on the surface of the rotating scraper 205 to clean the inner wall of the pipe to be processed. The high-speed rotation makes the inner wall of the pipe be polished smoother.

[0035] Example 2 Reference Figures 1 to 6 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the other side of the adjustment shaft 202a is located between the cleaning ring 202 and the gear ring 203, and a lever 202a-1 is fixedly arranged on this side, and the gear ring 203 is rotatably arranged on the outer wall of the rotating assembly 201, and the toothed side of the gear ring 203 faces the cleaning ring 202 side, and the gear ring 203 itself is located between the rotating assembly 201 and the cleaning ring 202. The lever 202a-1 is located inside the toothed side of the gear ring 203 and meshes with the gear ring 203.

[0036] Under the action of the centrifugal force generated by the high-speed rotation of the adjusting mechanism 200, the adjusting shaft 202a will rotate in the same direction. When the adjusting mechanism 200 rotates clockwise, the rotating scraper 205 will rotate and expand along with the adjusting shaft 202a. The expansion range of the rotating scraper 205 will be determined according to the diameter of the pipe. The larger the diameter, the greater the expansion range of the rotating scraper 205. In the end, the rotating scraper 205 will still fit the inner wall of the pipe.

[0037] Since the lever 202a-1 is meshed with the toothed ring 203, the rotating scraper 205 follows the movement of the adjusting shaft 202a, and the toothed ring 203 also starts to rotate. The rotating assembly 201 is fixedly provided with a control hole 201a in the horizontal direction, and the locking unit 204 is arranged in the control hole 201a. The locking unit 204 is elastically connected to the rotating assembly 201 to ensure that the locking unit 204 has the ability to reset after being pushed.

[0038] A one-way torsion bar 204a is provided at one end of the locking unit 204, and a limit block 204a-1 is fixedly installed on the top of the one-way torsion bar 204a. The limit block 204a-1 extends into the gear ring 203 and meshes with the gear ring 203. The one-way torsion bar 204a can only rotate in one direction. Therefore, when the rotating scraper 205 is unfolded to drive the gear ring 203 to move, it will not be blocked by the one-way torsion bar 204a and the limit block 204a-1. The one-way torsion bar 204a is only used to prevent the reverse movement of the gear ring 203 from causing the rotating scraper 205 to shrink and affect the grinding effect.

[0039] There may be pits or protrusions in the unpolished pipe, which will affect the working efficiency of conventional grinding equipment. Since the rotating scraper 205 can rotate and expand along with the adjusting shaft 202a, and will not shrink under the action of the one-way torsion bar 204a, it can effectively grind when encountering protrusions, and can continue to go deep into the depression for processing when encountering depressions. It is more flexible, has strong tolerance, and is adaptable to the inner diameters of pipes under various conditions.

[0040] A matching platform 104 is fixed on the outer wall of the main shaft 103 . The matching platform 104 is fixed between the stabilizing claw 101 and the adjusting mechanism 200 . A protruding matching ring 104 a is fixedly provided on the side of the matching platform 104 facing the adjusting mechanism 200 . The matching ring 104 a corresponds to the locking unit 204 .

[0041] During the operation of the entire device, the rotating scraper 205 on the adjusting mechanism 200 is in a contracted state by default, and the adjusting mechanism 200 is also in contact with the matching ring 104a on the matching platform 104. The matching ring 104a lifts up the locking unit 204 so that the limit block 204a-1 and the gear ring 203 are misaligned. At this time, the gear ring 203 and the adjusting shaft 202a are not restricted.

[0042] When the device is turned on, the adjustment mechanism 200 starts to rotate clockwise and can start to move from left to right along the main shaft 103 toward the matching claw 105 to gradually grind the inner wall of the pipe. The adjustment mechanism 200 starts to separate from the matching ring 104a, so the locking unit 204 is reset under the elastic effect, and the one-way torsion bar 204a starts to work.

[0043] When the grinding is finished and the adjusting mechanism 200 needs to be recovered, it is only necessary to operate the main control assembly 102 to make the adjusting mechanism 200 rotate counterclockwise to provide counterclockwise centrifugal force. However, at this time, under the action of the one-way torsion bar 204a, the gear ring 203 and the adjusting shaft 202a cannot rotate in the opposite direction until the adjusting mechanism 200 begins to gradually move along the main shaft 103 toward the stabilizing claw 101.

[0044] During the resetting process, the adjustment mechanism 200 begins to contact the matching ring 104a, and the matching ring 104a lifts up the locking unit 204 again, so that the limit block 204a-1 and the gear ring 203 are misaligned. Since the adjustment mechanism 200 rotates counterclockwise, the rotating scraper 205 moves back in the opposite direction under the action of the counterclockwise centrifugal force. A connecting rod 201b is fixedly installed on one side of the control hole 201a, and the other end of the connecting rod 201b is fixedly connected to the cleaning ring 202. The cleaning ring 202 is fixedly connected to the rotating assembly 201 through the connecting rod 201b and moves synchronously.

[0045] Example 3 Reference Figures 1 to 8This embodiment is based on the previous embodiment, and is different from the previous embodiment in that an operating platform 102c is provided on the surface of the main control assembly 102. The mating claw 105 is fixedly provided at the other end of the main shaft 103, and a fixture 105a is installed on the other side of the mating claw 105. The fixture 105a is used to assist in the fixed installation of the mating claw 105. An air inlet 105a-1 is fixedly provided on the outside of the fixture 105a, and external airflow can enter the pipe through the air inlet 105a-1. An absorption unit 102a is fixedly provided on the side of the main control assembly 102 facing the stabilizing claw 101. Electrostatic precipitators 106 are fixedly installed inside the absorption unit 102a and the fixture 105a, and the main control assembly 102 is electrically connected to the electrostatic precipitator 106.

[0046] By turning on the absorption unit 102a and the electrostatic precipitator 106 through the main control assembly 102, the dust particles left over from grinding can be absorbed and cleaned. Under the action of the external airflow introduced by the air inlet 105a-1, the absorption unit 102a will transport the absorbed dust particles to any container through the transmission hole 102a-1 fixedly opened on one side of the absorption unit 102a. It only requires to set a discharge pipe or a containing bag on the transmission hole 102a-1.

[0047] The auxiliary mechanism 300 is used to cooperate with the staff to monitor the operation degree of the entire device and the grinding degree of the inner wall of the pipeline. Three slide rails 301 are fixedly installed on the other side of the rotating assembly 201. The sensor 302 is set in the slide rail 301. The other end of the sensor 302 is connected to the bottom of the slide rail 301 through a tension spring. A through groove 301a is opened at the bottom of each slide rail 301, and the bottom of the sensor 302 passes through the through groove 301a.

[0048] Three driving rods 303 are fixedly arranged on the other side of the gear ring 203 to correspond to the three sensors 302. When the rotating scraper 205 is unfolded to drive the gear ring 203 to move, the gear ring 203 rotates to drive the three driving rods 303 to push the sensors 302 to move and extend out of the slide rail 301. Usually, the sensors 302 can be retracted in the slide rail 301 to be protected by the slide rail 301. The sensors 302 can monitor the cleaning of the inner wall of the pipeline under the control and cooperation of the main control assembly 102. The main control assembly 102 is electrically connected to the sensors 302, and the sensors 302 can reflect the situation in real time to the operating platform 102c set on the surface of the main control assembly 102.

[0049] During the reset process, the adjustment mechanism 200 begins to contact the matching ring 104a, and the matching ring 104a lifts up the locking unit 204 again, causing the limit block 204a-1 and the toothed ring 203 to be misaligned. Since the adjustment mechanism 200 rotates counterclockwise, the rotating scraper 205 moves in the opposite direction and retracts under the action of the counterclockwise centrifugal force. At this time, the toothed ring 203 rotates in the opposite direction and resets, and the sensor 302 is no longer pushed by the driving rod 303, and it rotates back to the original position under the action of the tension spring.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
