Description

Technical Field

[0001] The invention relates to the technical field of metal finishing treatment, in particular to a pipeline inner wall grinding and cleaning device. Background Art

[0002] In many industrial applications, the quality of the inner wall of metal pipes plays a vital role in the safety, efficiency and life of the entire system. In the direction of liquid flow, the roughness, sediment accumulation and corrosion of the inner wall will significantly affect the flow efficiency of the fluid and increase maintenance costs. In the direction of the transmission physical line, some metal pipe walls are prone to sharp and uneven locations such as burrs after rough processing. Cables are easily scratched by sharp burrs during transportation, thus affecting the service life of the cables.

[0003] In existing conventional construction scenarios, manual processing methods are inefficient and unstable. When faced with low-strength metals or other materials, inappropriate or excessive construction methods can easily damage the pipe wall. The sharp end of the inner wall can also easily cause damage to the hands of construction workers. In some cases, grinders are used for processing. However, conventional grinders are limited in size and cannot cope well with pipe walls of different inner diameters. Manual adjustment is often required, and efficiency still needs to be improved. After the ordinary grinding method is completed, additional processes are still required to clean the debris in the pipe wall.

[0004] Therefore, a pipeline inner wall grinding and cleaning device is needed that can automatically adapt to pipe walls of different inner diameters, monitor the grinding status, achieve a uniform grinding effect without damaging the pipe wall, and has the function of cleaning debris to meet the needs of the existing environment.

DETAILED DESCRIPTION

[0035] 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.

[0036] Example 1

[0037] Reference Figure 1 to Figure 5 , this embodiment provides a pipeline inner wall grinding and cleaning device.

[0038] The stabilizing mechanism 100 is used to fix the entire pipeline inner wall grinding and cleaning device on one side of the pipeline to be processed. The control platform 101 can operate and control the movement of the device. A display screen is also provided on the surface of the control platform 101 to facilitate the staff to read and control. A limit plate 102 is also fixedly provided on one side of the control platform 101. Three locking components 103 are provided on the outer wall of the limit plate 102. The locking components 103 are used to clamp and limit the pipe mouth of the pipeline to be processed to ensure that the whole device can be fixed firmly for subsequent grinding treatment. The outer wall of the limit plate 102 is fixedly provided with a locking hole 102a, and each locking hole 102a corresponds to a locking component 103. The locking component 103 can slide along the inner wall of the locking hole 102a, and the bottom of the locking component 103 is elastically connected to the bottom of the locking hole 102a. Under the action of elastic force, the locking component 103 can clamp the pipeline to be processed.

[0039] The motion mechanism 200 can continuously move in the pipeline to clean the pipeline wall. A conductive rod 201 is fixedly arranged on the side of the limit plate 102 facing the pipeline. A sliding cylinder 202 is arranged on the outer wall of the conductive rod 201. The sliding cylinder 202 itself can move horizontally along the conductive rod 201. The sliding cylinder 202 is electrically connected to the control platform 101. Under the operation of the control platform 101, the sliding cylinder 202 can be manipulated to move linearly along the conductive rod 201 in the pipeline. A power ring 203 is rotatably arranged on the other side of the sliding cylinder 202. The power ring 203 is also electrically connected to the control platform 101. The control platform 101 can control the power ring 203 to rotate. The power ring 203 is the core rotation drive structure of the entire device. A cleaning ring 204 is rotatably arranged on the outer wall of the sliding cylinder 202. The cleaning ring 204 itself does not rotate. When the power ring 203 rotates, it can contact the cleaning ring 204 and drive the cleaning ring 204 to rotate synchronously.

[0040] The adjustment mechanism 300 is used to control the adaptability of the cleaning ring 204 to pipes with different inner diameters. The outer wall of the power ring 203 is elastically provided with a telescopic lever 301, and the telescopic lever 301 is located between the power ring 203 and the cleaning ring 204. A corresponding groove is provided on the inner wall of the cleaning ring 204, and a matching card plate 302 is slidably provided in the groove, and the other end of the matching card plate 302 is connected to the groove by a spring. Since the groove is arc-shaped, the sliding track of the matching card plate 302 is also annular. The inner side of the matching card plate 302 extends through the cleaning ring 204 and faces the direction of the power ring 203. When the power ring 203 rotates, the telescopic lever 301 will contact and push the matching card plate 302. After the telescopic lever 301 continues to squeeze the matching card plate 302 to the limit position, the matching card plate 302 can no longer move, so the cleaning ring 204 at this time will be driven to rotate synchronously under the rotation of the power ring 203.

[0041] The outer wall of the cleaning ring 204 is provided with a grinding head 303, and the bottom of the grinding head 303 is elastically connected to the cleaning ring 204. One end of the matching card plate 302 is connected to the groove by a spring, and the other end is provided with a clamping protrusion facing the grinding head 303, which is clamped and matched with the grinding head 303. In the default state, the grinding head 303 is in a compressed state and locked by the clamping protrusion of the matching card plate 302. Only when the power ring 203 starts to move, it drives the movement of the matching card plate 302 and unlocks the grinding head 303. The grinding head 303 is thus released and extended until it contacts the inner wall of the pipe to be polished. Under the action of the elastic force, the grinding head 303 can fully contact the inner wall of the pipe and perform the grinding process under the continuous rotation of the power ring 203.

[0042] Example 2

[0043] Reference Figures 1 to 8 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0044] The outer wall of the conductive rod 201 is fixedly provided with a docking groove 201a, and the sliding cylinder 202 can cooperate with the docking groove 201a and slide linearly along the docking groove 201a. The sliding cylinder 202 is electrically connected to the control platform 101. Under the operation of the control platform 101, the sliding cylinder 202 can be manipulated to move linearly along the conductive rod 201. The power ring 203 is also electrically connected to the control platform 101, and the control platform 101 can control the power ring 203 to rotate. The outer wall of the power ring 203 is fixedly provided with three accommodating protrusions 203a.

[0045] An airtight groove 203a-1 is provided on the surface of each accommodating protrusion 203a, a sealing sheet 203a-2 is fixedly provided on the top of the airtight groove 203a-1, and an accommodating hole 203a-3 is provided in the center of the sealing sheet 203a-2. The end of the telescopic rod 301 slides in the airtight groove 203a-1, and the upper part of the telescopic rod 301 passes through the accommodating hole 203a-3 and is located above the sealing sheet 203a-2. The bottom of the telescopic rod 301 and the bottom of the airtight groove 203a-1 are elastically connected, and the top of the telescopic rod 301 is set to a spherical surface. On both sides of the airtight groove 203a-1, two exhaust holes 203b are provided on the surface of the accommodating protrusion 203a. The exhaust holes 203b extend exhaust channels 203b-1 toward the inside of the accommodating protrusion 203a. The exhaust channels 203b-1 are connected to the inner wall of the airtight groove 203a-1, and the connection position is above the airtight groove 203a-1.

[0046] The side wall of the cleaning ring 204 is fixedly provided with a slide groove 204a, and the slide groove 204a is provided with three sections, and each section of the slide groove 204a corresponds to a matching card plate 302. The slide groove 204a is arc-shaped, and the bottom of the slide groove 204a is connected with the inner wall of the cleaning ring 204, and the matching card plate 302 can slide along the slide groove 204a in an arc. Since the bottom of the slide groove 204a is connected with the inner wall of the cleaning ring 204, the matching rod 302b fixedly provided on the inner wall of the matching card plate 302 can pass through the cleaning ring 204 and extend between the cleaning ring 204 and the power ring 203. The matching rod 302b is used to contact the telescopic lever 301. A spring 302a is fixedly provided on one side of the matching card plate 302, and the other end of the spring 302a is fixedly connected with the inner wall of the slide groove 204a. When the power ring 203 rotates, the telescopic lever 301 will contact the matching rod 302b and push the matching clamping plate 302, and the matching clamping plate 302 can no longer move. At this time, the cleaning ring 204 will be driven to rotate synchronously under the rotation of the power ring 203, and a limit bolt 302c is fixedly provided on the other side of the matching clamping plate 302, and the limit bolt 302c will move with the matching clamping plate 302.

[0047] In the default state, the entire pipeline inner wall grinding and cleaning device uses low power to grind the inner wall of the pipeline. In order to prevent some pipeline materials from being not hard enough, directly using high power grinding may damage the pipeline. The power ring 203 rotates in the low power state, first using the telescopic lever 301 to contact the matching rod 302b to drive the matching clamping plate 302 to move, and the limit bolt 302c follows the movement of the matching clamping plate 302 to release the lock on the grinding head 303, so that the grinding head 303 is released and extended. Under the action of elastic force, the grinding head 303 can fully contact the inner wall of the pipeline and perform grinding under the continuous rotation of the power ring 203.

[0048] In the low power state, the top of the telescopic lever 301 contacts the matching rod 302b. Even if the bottom of the telescopic lever 301 and the airtight groove 203a-1 are elastically connected, it will not be affected because the rotation speed of the power ring 203 is not fast in the low power state and is controlled within a reasonable range. When it is necessary to increase the power to meet the needs of different environments, it is only necessary to increase the rotation speed of the power ring 203 by operating the control platform 101. At this time, the whole device is in a high power state. After the speed of the power ring 203 is increased, the telescopic lever 301 will break the original force range when in contact with the matching rod 302b. The bottom of the matching rod 302b is set as an inclined surface, and the telescopic lever 301 will be pushed by the bottom of the matching rod 302b, thereby descending along the airtight groove 203a-1.

[0049] When the telescopic lever 301 descends along the airtight groove 203a-1, it will be linked with the exhaust channel 203b-1 and the exhaust hole 203b to perform a suction movement. When the telescopic lever 301 is squeezed and descended, it will be reset under the action of the elastic connection with the bottom of the airtight groove 203a-1. At this time, the exhaust channel 203b-1 and the exhaust hole 203b will be linked to perform a push movement. Since the size of the exhaust hole 203b is very small, the reset of the telescopic lever 301 will be blocked to a certain extent under the action of air pressure, and the reset of the telescopic lever 301 will be slowed down. This step is to prevent the telescopic lever 301 from resetting too quickly under the action of elastic force, so that the telescopic lever 301 can be more conveniently dislocated with the matching rod 302b for subsequent movement.

[0050] Example 3

[0051] Reference Figures 1 to 12 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0052] The outer wall of the cleaning ring 204 is fixedly provided with three adjustment grooves 204b, and each adjustment groove 204b corresponds to a grinding head 303. A connecting block 303a is fixedly provided at the other end of the grinding head 303, and the connecting block 303a and the adjustment groove 204b are connected by an elastic telescopic rod 303a-1. A telescopic hole 204b-1 is fixedly provided at the bottom of the adjustment groove 204b, and the other end of the connecting block 303a passes through the telescopic hole 204b-1 and is located between the cleaning ring 204 and the power ring 203, and the bottom of the connecting block 303a is set as a parallelogram surface. A limiting hole 204b-2 is fixedly provided on the side wall of the adjustment groove 204b, and the limiting hole 204b-2 is connected to the slide groove 204a through and the limiting hole 204b-2 is docked with the limiting bolt 302c. A locking groove 303a-2 is fixedly provided on one side of the connecting block 303a facing the limiting hole 204b-2 to cooperate with the limiting bolt 302c, ensuring that when the device is in the default non-starting state, the grinding head 303 is locked through the locking cooperation between the locking groove 303a-2 and the limiting bolt 302c.

[0053] A sensing terminal 303a-3 is fixedly provided on the top of each connection block 303a. The sensing terminal 303a-3 is electrically connected to the control platform 101. The sensing terminal 303a-3 can monitor the inner wall condition of the pipeline in real time and transmit it back to the operation terminal 101a on the control platform 101 for the staff to view.

[0054] The bottom of the connecting block 303a is set as a parallelogram surface. When the power needs to be increased to meet the needs of different environments, the rotation speed of the power ring 203 is accelerated, and the whole device is in a high-power state. After the speed of the power ring 203 is accelerated, the telescopic lever 301 will break the original force range when it contacts the matching rod 302b. The bottom of the matching rod 302b is set as an inclined surface. The telescopic lever 301 will be pushed by the bottom of the matching rod 302b, thereby descending along the airtight groove 203a-1. Under the action of air pressure, the resetting of the telescopic lever 301 becomes slower. At this time, the telescopic lever 301 will be in the power ring 203. The power ring 203 rotates and contacts the inclined surface of one side of the connecting block 303a. The movement of the power ring 203 will drive the telescopic lever 301 to press against the connecting block 303a. The inclined surface causes the connecting block 303a to continuously receive an upward force, so that the grinding head 303 can press against the inner wall of the pipe more efficiently and firmly. Compared with the low-power state, the grinding head 303 only presses against the inner wall of the pipe under the action of the elastic telescopic lever 303a-1. At this time, the contact between the grinding head 303 and the inner wall of the pipe is more sufficient. In addition, the rotation speed of the power ring 203 is accelerated. At this time, the overall grinding efficiency of the device is improved, and it can be used to deal with harder and more difficult to handle inner walls of pipes. When not in contact with the telescopic lever 301, the matching card plate 302 will also be reset under the action of the spring 302a, but because the connecting block 303a is already in an ascending state at this time, the stop bolt 302c on one side of the matching card plate 302 will press against the connecting block 303a, so that the connecting block 303a will not retract as much as possible, so that the grinding head 303 and the inner wall of the pipe are more fully contacted.

[0055] When the device needs to be reset to return the extended grinding head 303 to its original position, it is only necessary to operate the power ring 203 to quickly rotate through the operation terminal 101a. The telescopic lever 301 will follow the power ring 203 to repeat the previous movement process in reverse, and finally contact the other side of the bottom of the connecting block 303a. The other side of the bottom of the connecting block 303a is also a slope. Under the rotation of the power ring 203, the connecting block 303a will be gradually driven to retract. When the connecting block 303a retracts to the initial position, the positioning groove 303a-2 on one side of the connecting block 303a will be aligned with the limit bolt 302c, and the limit bolt 302c can enter the connecting block 303a again to lock the connecting block 303a. The operation terminal 101a simultaneously controls the sliding cylinder 202 to return along the conductive rod 201.

[0056] An exhaust fan is provided inside the sliding cylinder 202, and a trigger button 202a is provided at the end of the sliding cylinder 202. The trigger button 202a is electrically connected to the exhaust fan inside the sliding cylinder 202. When it is necessary to blow away the debris inside the pipeline, it is only necessary to use the operation terminal 101a to drive the sliding cylinder 202 to move to the end of the conduction rod 201, so that the trigger button 202a at the end of the sliding cylinder 202 contacts the side wall of the limit plate 102, thereby pressing the trigger button, and the exhaust fan moves and directly blows the inner wall of the pipeline through the exhaust hole 202b opened at the front end of the sliding cylinder 202. After the blowing is completed, it is only necessary to control the sliding cylinder 202 to move forward and release the trigger button 202a, and the whole blowing process is completed.

[0057] 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.
