Description

Technical Field

[0001] The present invention relates to a testing equipment maintenance system, and in particular to a high-speed centrifugal force testing equipment tapered pipeline maintenance system and a use method thereof. Background Art

[0002] High-speed centrifugal force testing equipment is a special equipment used to test the working conditions of various components on aircraft under specific centrifugal force conditions. The high-speed centrifugal force testing equipment is equipped with a conical pipeline. By setting a rotating path on the conical pipeline of the high-speed centrifugal force testing equipment, the component to be tested moves on the rotating path. The cleanliness and smoothness of the rotating path play an important role in the motion characteristics of the object's acceleration. If there are problems with the cleanliness and smoothness, the friction of the object will increase, affecting the accelerated motion of the object, and thus affecting the measurement of the centrifugal force of the component. Therefore, the inner surface of the conical pipeline needs to be maintained regularly.

[0003] Common pipe cleaning equipment uses a motor to drive the brush head to rotate to clean the inner surface of the pipe. For non-flat surfaces, an elastic support device such as a spring cylinder is usually used to connect the motor and the brush head.

[0004] Although these two cleaning methods can effectively clean the surface of components, they still have the following defects:

[0005] 1. Manual cleaning or grinding is inefficient, and manual operation is difficult to meet the requirements of high-precision cleaning or grinding.

[0006] 2. When the elastic support device in the existing pipeline cleaning equipment is used in a tapered pipeline, its elastic force will increase as the diameter of the tapered pipeline decreases, resulting in increased pressure of the brush head on the surface of the component and failure to ensure uniform grinding.

[0007] The information disclosed in this background technology section is only intended to increase understanding of the overall background of the application and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field.

[0014] The telescopic signal input end of the linear motor is signal-connected to the telescopic signal output end of the linear motor controller, the distance signal output end of the ranging sensor is signal-connected to the distance signal input end of the linear motor controller, and the telescopic signal input end of the linear motor controller is signal-connected to the telescopic signal output end of the main controller.

The top of the pressure plate is detachably provided with a maintenance sheet, and the bottom of the pressure plate is fixedly provided with a universal joint. The universal joint is hinged to the end of the linear motor push rod, and the maintenance sheet is an elastic flat plate structure.

[0016] The pressure plate is a hard flat plate structure. The maintenance module further comprises an airbag, which is fixedly arranged on the pressure plate. The maintenance sheet is fixedly arranged on the side of the airbag far from the pressure plate.

[0017] A pressure sensor is provided between the pressure plate and the airbag. The pressure sensor is fixedly provided on the pressure plate. The pressure signal output end of the pressure sensor is signal-connected to the pressure signal input end of the wireless transmission module.

[0018] The rotation drive module is further provided with a wireless transmission module, the signal output end of the wireless transmission module is signal-connected to the telescopic signal input end of the linear motor controller, and the wireless transmission module is wirelessly connected to the main controller.

[0019] A motor lifting bracket is fixedly provided at the bottom of the rotating motor, the end of the lead screw away from the rotating motor is inserted into and fitted with the inner ring of the bearing, and a bearing lifting bracket is fixedly provided at the bottom of the outer ring of the bearing.

[0020] The maintenance sheet is a cleaning sheet or a grinding sheet.

[0021] A method for using a tapered pipe maintenance system for high-speed centrifugal force testing equipment, the method comprising:

[0022] Step 1: Install the maintenance system, place the rotary drive module on the lead screw, and manually rotate the rotary drive module to move the rotary drive module to the end of the lead screw close to the rotary motor. When the rotary drive module is in place, pass the lead screw through the tapered pipe and insert the end of the lead screw into the inner ring of the bearing. After the lead screw is inserted into the bearing, adjust the motor lifting bracket and the bearing lifting bracket to make the lead screw coaxial with the tapered pipe. When the lead screw and the tapered pipe are coaxial, proceed to the second step of selecting the working mode.

[0023] Step 2: Select the working mode, and the operator observes the inner surface of the tapered pipe. If there are scratches or dents on the inner surface of the tapered pipe, the operator installs the grinding sheet on each pressure plate and proceeds to the third step of grinding preparation. If there are no scratches or dents on the inner surface of the tapered pipe, but there is dirt, the operator installs the cleaning sheet on each pressure plate and proceeds to the sixth step of cleaning preparation.

[0024] Step 3: Grinding preparation: the operator starts the rotating motor, the braking device and each telescopic maintenance arm through the main controller. The main controller drives the brake caliper of the braking device to clamp the lead screw. At the same time, the linear motors in each telescopic maintenance arm start working to extend the push rods of each linear motor. When the pressure on the pressure sensor reaches the pre-compression value, the pressure sensor sends a pressure signal to the wireless transmission module. After receiving the pressure signal from the pressure sensor, the wireless transmission module sends a signal to the main controller. At this time, the main controller drives the linear motor to stop working. When all linear motors stop working, the fourth step of circumferential grinding begins.

[0025] Step 4: Circumferential grinding. When all linear motors stop working, the main controller drives the rotary motor to start working. At the same time, the rotary motor drives the lead screw to start rotating, and the lead screw drives the rotary drive module to rotate synchronously. At this time, the pressure sensor continuously monitors the pressure on the pressure plate. When the pressure on the pressure plate is higher than the grinding pressure value, the main controller drives the linear motor to shorten. When the pressure on the pressure plate is lower than the grinding pressure value, the main controller drives the linear motor to extend until the pressure on the pressure plate is the same as the grinding pressure value. When the rotary encoder detects that the lead screw has rotated one circle, the rotary encoder sends a signal to the main controller and enters the fifth step of linear grinding.

[0026] Step 5: Linear grinding. After the main controller receives the signal from the rotary encoder, it controls the brake caliper of the braking device to release. At this time, the screw and the rotary drive module are disengaged from each other. The rotary drive module rotates with the screw under the friction between the maintenance plate and the tapered pipe. At this time, the screw continues to rotate to drive the rotary drive module to move linearly along the direction of the screw. At this time, the pressure sensor continuously monitors the pressure on the pressure plate. When the pressure on the pressure plate is higher than the grinding pressure value, the main controller drives the linear motor to shorten. When the pressure on the pressure plate is lower than the grinding pressure value, the main controller drives the linear motor to extend until the pressure on the pressure plate is the same as the grinding pressure value. At the same time, when the rotary encoder detects that the number of screw rotations multiplied by the screw pitch is equal to the maintenance plate length, and the pressure detected by the pressure sensor reaches the grinding pressure value, the rotary encoder sends a signal to the main controller. After receiving the signal from the rotary encoder, the main controller controls the brake caliper of the braking device to clamp and returns to the third step of circumferential maintenance. When the pressure detected by the pressure sensor is lower than the grinding pressure value and the distance sensor detects that the linear motor has extended to the maximum length, the sixth step of cleaning preparation is entered.

[0027] Step 6: Cleaning preparation. The operator blows the inner surface of the tapered pipe with high-pressure air. When there is no grinding debris on the inner surface of the tapered pipe, the operator starts the rotating motor, the braking device and each telescopic maintenance arm through the main controller. The main controller drives the brake caliper of the braking device to loosen the screw. At the same time, the linear motor in each telescopic maintenance arm starts working, shortening the push rod of each linear motor to the shortest. When the distance measuring sensor detects that the push rod is shortened to the shortest, the distance measuring sensor sends a distance signal to the wireless transmission module. After receiving the distance signal from the distance measuring sensor, the wireless transmission module sends a signal to the main controller. At this time, the main controller drives the linear motor to stop working. At the same time, the rotating motor starts working to move the rotating drive module toward the rotating motor. When the operator observes that the rotating drive module has left the tapered pipe, the operator turns off the rotating motor through the main controller and enters the seventh step of circumferential cleaning.

[0028] Step 7: Circumferential cleaning. After the rotary drive module leaves the tapered pipe, the operator drives the rotary motor through the main controller to start working. At the same time, the rotary motor drives the lead screw to start rotating, and the lead screw drives the rotary drive module to rotate synchronously. At this time, the pressure sensor continuously monitors the pressure on the pressure plate. When the pressure on the pressure plate is higher than the cleaning pressure value, the main controller drives the linear motor to shorten. When the pressure on the pressure plate is lower than the cleaning pressure value, the main controller drives the linear motor to extend until the pressure on the pressure plate is the same as the cleaning pressure value. When the rotary encoder detects that the lead screw has rotated one circle, the rotary encoder sends a signal to the main controller and enters the eighth step of linear cleaning.

[0029] Step 8: Linear cleaning. After the main controller receives the signal from the rotary encoder, it controls the brake caliper of the braking device to release. At this time, the screw and the rotary drive module are disengaged from each other. The rotary drive module rotates with the screw under the friction between the maintenance plate and the tapered pipe. At this time, the screw continues to rotate, driving the rotary drive module to move linearly along the direction of the screw. At this time, the pressure sensor continuously monitors the pressure on the pressure plate. When the pressure on the pressure plate is higher than the cleaning pressure value, the main controller drives the linear motor to shorten. When the pressure on the pressure plate is lower than the cleaning pressure value, the main controller drives the linear motor to extend until the pressure on the pressure plate is the same as the cleaning pressure value. At the same time, when the rotary encoder detects that the number of screw rotations multiplied by the screw pitch is equal to the maintenance plate length, and the pressure detected by the pressure sensor reaches the cleaning pressure value, the rotary encoder sends a signal to the main controller. After receiving the signal from the rotary encoder, the main controller controls the brake caliper of the braking device to clamp and returns to the third step of circumferential maintenance. When the pressure detected by the pressure sensor is lower than the cleaning pressure value and the distance sensor detects that the linear motor is extended to the maximum length, the usage method ends.

[0030] The pre-compaction value is 0.5 to 1.5 MPa, the grinding pressure value is 2.5 to 3.5 MPa, and the cleaning pressure value is 1.5 to 2.5 MPa.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention relates to a conical pipe maintenance system for high-speed centrifugal force testing equipment. The power output shaft of a rotary motor is coaxially connected to the end of a lead screw. A rotary drive module is mounted on the lead screw, and a brake device is fixedly mounted on the rotary drive module. Multiple telescopic maintenance arms are evenly arranged on the sidewalls of the rotary drive module, and the ends of the telescopic maintenance arms are fixedly mounted with maintenance modules. The rotary motor controls the rotation of the lead screw, allowing the maintenance modules to uniformly maintain the inner surface of the conical pipe, effectively improving maintenance efficiency. Therefore, this design allows the rotary motor to control the maintenance modules to uniformly maintain the inner surface of the conical pipe, effectively improving maintenance efficiency.

[0033] 2. In a conical pipe maintenance system for high-speed centrifugal force testing equipment, the present invention employs a rigid, flat plate pressure plate with an airbag fixedly mounted on it. A maintenance sheet is fixedly mounted on the side of the airbag distal to the pressure plate. When the telescopic maintenance arm extends, pressing the maintenance module against the inner wall of the conical pipe, the airbag deforms. Since the pressure within the airbag is equal, the maintenance sheet maintains the inner surface of the conical pipe with the same pressure at all locations. Therefore, this design ensures that the pressure of the maintenance sheet on the inner surface of the conical pipe is uniform at all locations, effectively improving maintenance accuracy.

[0034] 3. In the method for using a conical pipeline maintenance system for high-speed centrifugal force testing equipment disclosed herein, the power output shaft of the rotary motor is connected to the detection end signal of a rotary encoder. A braking device is fixedly installed on the rotary drive module. The telescopic maintenance arm is a linear motor equipped with a distance sensor for measuring the length of the push rod. A pressure sensor for measuring the pressure on the pressure plate is also installed within the maintenance module. A controller collects data measured by the distance sensor and pressure sensor via a signal collector and controls the movement of the rotary motor and braking device based on this data. Therefore, this design can precisely control the movement of the rotary motor and braking device based on the push rod length, the pressure on the pressure plate, and the rotation angle of the rotary motor, effectively improving maintenance accuracy.

[0052] The maintenance sheet 72 is a cleaning sheet or a grinding sheet.

[0053] A method for using a tapered pipe maintenance system for high-speed centrifugal force testing equipment, the method comprising:

[0054] Step 1: Install the maintenance system, sleeve the rotation drive module 4 on the screw 3, and manually rotate the rotation drive module 4 to move the rotation drive module 4 to the end of the screw 3 near the rotating motor 1. When the rotation drive module 4 is in place, pass the screw 3 through the tapered pipe 9 and insert the end of the screw 3 into the inner ring of the bearing 32. After the screw 3 is inserted into the bearing 32, adjust the motor lifting bracket 11 and the bearing lifting bracket 31 to make the screw 3 coaxial with the tapered pipe 9. When the screw 3 is coaxial with the tapered pipe 9, proceed to the second step of selecting the working mode.

[0055] Step 2: Select the working mode, and the operator observes the inner surface of the tapered pipe. If there are scratches or dents on the inner surface of the tapered pipe, the operator installs the grinding sheet on each pressure plate 71 and proceeds to the third step of grinding preparation. If there are no scratches or dents on the inner surface of the tapered pipe, but there is dirt, the operator installs the cleaning sheet on each pressure plate 71 and proceeds to the sixth step of cleaning preparation.

[0056] Step 3: Grinding preparation: the operator starts the rotating motor 1, the brake device 42 and each telescopic maintenance arm 6 through the main controller 5. The main controller 5 drives the brake caliper of the brake device 42 to clamp the screw 3. At the same time, the linear motor 61 in each telescopic maintenance arm 6 starts to work, so that the push rod of each linear motor 61 extends. When the pressure on the pressure sensor 75 reaches the pre-compression value, the pressure sensor 75 sends a pressure signal to the wireless transmission module 8. After receiving the pressure signal from the pressure sensor 75, the wireless transmission module 8 sends a signal to the main controller 5. At this time, the main controller 5 drives the linear motor 61 to stop working. When all the linear motors 61 stop working, the fourth step of circumferential grinding is entered.

[0057] Step 4: Circumferential grinding. When all linear motors 61 stop working, the main controller 5 drives the rotary motor 1 to start working. At the same time, the rotary motor 1 drives the lead screw 3 to start rotating, and the lead screw 3 drives the rotary drive module 4 to rotate synchronously. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the grinding pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the grinding pressure value, the main controller 5 drives the linear motor 61 to extend until the pressure on the pressure plate 71 is the same as the grinding pressure value. When the rotary encoder 2 detects that the lead screw 3 rotates one circle, the rotary encoder 2 sends a signal to the main controller 5 and enters the fifth step of linear grinding.

[0058] Step 5: Linear grinding. After the main controller 5 receives the signal from the rotary encoder 2, it controls the brake caliper of the brake device 42 to release. At this time, the screw 3 and the rotary drive module 4 are separated from each other. The rotary drive module 4 rotates with the screw 3 under the action of the friction between the maintenance plate 72 and the tapered pipe 9. At this time, the screw 3 continues to rotate and drives the rotary drive module 4 to move linearly along the direction of the screw 3. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the grinding pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the grinding pressure value, the main controller 5 drives the linear motor 61 to shorten. The machine 61 is extended until the pressure on the pressure plate 71 is the same as the grinding pressure value. At the same time, when the rotary encoder 2 detects that the number of rotations of the screw 3 multiplied by the pitch of the screw 3 is equal to the length of the maintenance sheet 72, and the pressure detected by the pressure sensor 75 reaches the grinding pressure value, the rotary encoder 2 sends a signal to the main controller 5. After receiving the signal from the rotary encoder 2, the main controller 5 controls the brake caliper of the braking device 42 to clamp, and returns to the third circumferential maintenance step. When the pressure detected by the pressure sensor 75 is lower than the grinding pressure value, and the distance sensor 63 detects that the linear motor 61 is extended to the maximum length, the sixth cleaning preparation step is entered.

[0059] Step 6: Cleaning preparation. The operator blows the inner surface of the tapered pipe with high-pressure air. When there is no grinding debris on the inner surface of the tapered pipe, the operator starts the rotating motor 1, the braking device 42 and each telescopic maintenance arm 6 through the main controller 5. The main controller 5 drives the brake caliper of the braking device 42 to release the screw 3. At the same time, the linear motor 61 in each telescopic maintenance arm 6 starts to work, so that the push rod of each linear motor 61 is shortened to the shortest. When the distance sensor 63 detects that the push rod is shortened to the shortest, the distance sensor 63 sends a distance signal to the wireless transmission module 8. After receiving the distance signal sent by the distance sensor 63, the wireless transmission module 8 sends a signal to the main controller 5. At this time, the main controller 5 drives the linear motor 61 to stop working. At the same time, the rotating motor 1 starts to work to move the rotating drive module 4 in the direction of the rotating motor 1. When the operator observes that the rotating drive module 4 leaves the tapered pipe, the operator turns off the rotating motor 1 through the main controller 5 and enters the seventh circumferential cleaning step at the same time.

[0060] Step 7: Circumferential cleaning. After the rotary drive module 4 leaves the tapered pipe, the operator drives the rotary motor 1 through the main controller 5 to start working. At the same time, the rotary motor 1 drives the lead screw 3 to start rotating, and the lead screw 3 drives the rotary drive module 4 to rotate synchronously. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the cleaning pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the cleaning pressure value, the main controller 5 drives the linear motor 61 to extend until the pressure on the pressure plate 71 is the same as the cleaning pressure value. When the rotary encoder 2 detects that the lead screw 3 rotates one circle, the rotary encoder 2 sends a signal to the main controller 5 and enters the eighth step of linear cleaning.

[0061] Step 8: Linear cleaning. After receiving the signal from the rotary encoder 2, the main controller 5 controls the brake caliper of the braking device 42 to release. At this time, the screw 3 and the rotary drive module 4 are separated from each other. The rotary drive module 4 rotates with the screw 3 under the friction between the maintenance sheet 72 and the tapered pipe 9. At this time, the screw 3 continues to rotate and drives the rotary drive module 4 to move linearly along the direction of the screw 3. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the cleaning pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the cleaning pressure value, the main controller 5 drives The moving linear motor 61 is extended until the pressure on the pressure plate 71 is the same as the cleaning pressure value. At the same time, when the rotary encoder 2 detects that the number of rotations of the screw 3 multiplied by the pitch of the screw 3 is equal to the length of the maintenance plate 72, and the pressure detected by the pressure sensor 75 reaches the cleaning pressure value, the rotary encoder 2 sends a signal to the main controller 5. After receiving the signal from the rotary encoder 2, the main controller 5 controls the brake caliper of the braking device 42 to clamp, and returns to the third circumferential maintenance step. When the pressure detected by the pressure sensor 75 is lower than the cleaning pressure value, and the distance sensor 63 detects that the linear motor 61 is extended to the maximum length, the usage method ends.

[0062] The pre-compaction value is 0.5 to 1.5 MPa, the grinding pressure value is 2.5 to 3.5 MPa, and the cleaning pressure value is 1.5 to 2.5 MPa.

[0063] The principle of the present invention is described as follows:

[0064] The PID parameters of the main controller 5 in this design are set as follows:

[0065] Proportional gain: 56.37;

[0066] Integral gain: 320.0;

[0067] Differential gain: 0.1018.

[0068] In this design, the extended length of each linear motor 61 is detected by a distance measuring sensor 63.

[0070] A method for using a tapered pipe maintenance system for high-speed centrifugal force testing equipment, the method comprising:

[0071] Step 1: Install the maintenance system, sleeve the rotation drive module 4 on the screw 3, and manually rotate the rotation drive module 4 to move the rotation drive module 4 to the end of the screw 3 near the rotating motor 1. When the rotation drive module 4 is in place, pass the screw 3 through the tapered pipe 9 and insert the end of the screw 3 into the inner ring of the bearing 32. After the screw 3 is inserted into the bearing 32, adjust the motor lifting bracket 11 and the bearing lifting bracket 31 to make the screw 3 coaxial with the tapered pipe 9. When the screw 3 is coaxial with the tapered pipe 9, proceed to the second step of selecting the working mode.

[0072] Step 2: Select the working mode, and the operator observes the inner surface of the tapered pipe. If there are scratches or dents on the inner surface of the tapered pipe, the operator installs the grinding sheet on each pressure plate 71 and proceeds to the third step of grinding preparation. If there are no scratches or dents on the inner surface of the tapered pipe, but there is dirt, the operator installs the cleaning sheet on each pressure plate 71 and proceeds to the sixth step of cleaning preparation.

[0073] Step 3: Grinding preparation: the operator starts the rotating motor 1, the brake device 42 and each telescopic maintenance arm 6 through the main controller 5. The main controller 5 drives the brake caliper of the brake device 42 to clamp the screw 3. At the same time, the linear motor 61 in each telescopic maintenance arm 6 starts to work, so that the push rod of each linear motor 61 extends. When the pressure on the pressure sensor 75 reaches the pre-compression value, the pressure sensor 75 sends a pressure signal to the wireless transmission module 8. After receiving the pressure signal from the pressure sensor 75, the wireless transmission module 8 sends a signal to the main controller 5. At this time, the main controller 5 drives the linear motor 61 to stop working. When all the linear motors 61 stop working, the fourth step of circumferential grinding is entered.

[0074] Step 4: Circumferential grinding. When all linear motors 61 stop working, the main controller 5 drives the rotary motor 1 to start working. At the same time, the rotary motor 1 drives the lead screw 3 to start rotating, and the lead screw 3 drives the rotary drive module 4 to rotate synchronously. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the grinding pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the grinding pressure value, the main controller 5 drives the linear motor 61 to extend until the pressure on the pressure plate 71 is the same as the grinding pressure value. When the rotary encoder 2 detects that the lead screw 3 rotates one circle, the rotary encoder 2 sends a signal to the main controller 5 and enters the fifth step of linear grinding.

[0075] Step 5: Linear grinding. After the main controller 5 receives the signal from the rotary encoder 2, it controls the brake caliper of the brake device 42 to release. At this time, the screw 3 and the rotary drive module 4 are separated from each other. The rotary drive module 4 rotates with the screw 3 under the action of the friction between the maintenance plate 72 and the tapered pipe 9. At this time, the screw 3 continues to rotate and drives the rotary drive module 4 to move linearly along the direction of the screw 3. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the grinding pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the grinding pressure value, the main controller 5 drives the linear motor 61 to shorten. The machine 61 is extended until the pressure on the pressure plate 71 is the same as the grinding pressure value. At the same time, when the rotary encoder 2 detects that the number of rotations of the screw 3 multiplied by the pitch of the screw 3 is equal to the length of the maintenance sheet 72, and the pressure detected by the pressure sensor 75 reaches the grinding pressure value, the rotary encoder 2 sends a signal to the main controller 5. After receiving the signal from the rotary encoder 2, the main controller 5 controls the brake caliper of the braking device 42 to clamp, and returns to the third circumferential maintenance step. When the pressure detected by the pressure sensor 75 is lower than the grinding pressure value, and the distance sensor 63 detects that the linear motor 61 is extended to the maximum length, the sixth cleaning preparation step is entered.

[0076] Step 6: Cleaning preparation. The operator blows the inner surface of the tapered pipe with high-pressure air. When there is no grinding debris on the inner surface of the tapered pipe, the operator starts the rotating motor 1, the braking device 42 and each telescopic maintenance arm 6 through the main controller 5. The main controller 5 drives the brake caliper of the braking device 42 to release the screw 3. At the same time, the linear motor 61 in each telescopic maintenance arm 6 starts to work, so that the push rod of each linear motor 61 is shortened to the shortest. When the distance sensor 63 detects that the push rod is shortened to the shortest, the distance sensor 63 sends a distance signal to the wireless transmission module 8. After receiving the distance signal sent by the distance sensor 63, the wireless transmission module 8 sends a signal to the main controller 5. At this time, the main controller 5 drives the linear motor 61 to stop working. At the same time, the rotating motor 1 starts to work to move the rotating drive module 4 in the direction of the rotating motor 1. When the operator observes that the rotating drive module 4 leaves the tapered pipe, the operator turns off the rotating motor 1 through the main controller 5 and enters the seventh circumferential cleaning step at the same time.

[0077] Step 7: Circumferential cleaning. After the rotary drive module 4 leaves the tapered pipe, the operator drives the rotary motor 1 through the main controller 5 to start working. At the same time, the rotary motor 1 drives the lead screw 3 to start rotating, and the lead screw 3 drives the rotary drive module 4 to rotate synchronously. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the cleaning pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the cleaning pressure value, the main controller 5 drives the linear motor 61 to extend until the pressure on the pressure plate 71 is the same as the cleaning pressure value. When the rotary encoder 2 detects that the lead screw 3 rotates one circle, the rotary encoder 2 sends a signal to the main controller 5 and enters the eighth step of linear cleaning.

[0078] Step 8: Linear cleaning. After receiving the signal from the rotary encoder 2, the main controller 5 controls the brake caliper of the braking device 42 to release. At this time, the screw 3 and the rotary drive module 4 are separated from each other. The rotary drive module 4 rotates with the screw 3 under the friction between the maintenance sheet 72 and the tapered pipe 9. At this time, the screw 3 continues to rotate and drives the rotary drive module 4 to move linearly along the direction of the screw 3. At this time, the pressure sensor 75 continuously monitors the pressure on the pressure plate 71. When the pressure on the pressure plate 71 is higher than the cleaning pressure value, the main controller 5 drives the linear motor 61 to shorten. When the pressure on the pressure plate 71 is lower than the cleaning pressure value, the main controller 5 drives The moving linear motor 61 is extended until the pressure on the pressure plate 71 is the same as the cleaning pressure value. At the same time, when the rotary encoder 2 detects that the number of rotations of the screw 3 multiplied by the pitch of the screw 3 is equal to the length of the maintenance sheet 72, and the pressure detected by the pressure sensor 75 reaches the cleaning pressure value, the rotary encoder 2 sends a signal to the main controller 5. After receiving the signal from the rotary encoder 2, the main controller 5 controls the brake caliper of the braking device 42 to clamp, and returns to the third circumferential maintenance step. When the pressure detected by the pressure sensor 75 is lower than the cleaning pressure value, and the distance sensor 63 detects that the linear motor 61 is extended to the maximum length, the use method ends.

[0079] The pre-compaction value is 0.5 to 1.5 MPa, the grinding pressure value is 2.5 to 3.5 MPa, and the cleaning pressure value is 1.5 to 2.5 MPa.
