A grey cast iron machining auxiliary device

Abstract

The invention relates to the technical field of cast iron processing, and discloses a gray cast iron processing auxiliary device, comprising a grinding mechanism, which also includes a motor. A driving column is rotatably connected to the inner wall of the motor. The motor drives the driving column to rotate through a driving gear. The driving column drives the mounting plate to rotate synchronously through a mounting plate. When the driving column reaches a certain rotation speed, the mounting plate and the cross will generate centrifugal force. The centrifugal force will drive the configuration slider and the rotating rod to move outward, forcing the rotating rod to contact the inclined surface of the inclined surface. As the rotation speed continues to increase, the force of the rotating rod to expand outward continues to increase. Finally, the rotating rod forces the inclined surface to move sideways along the through hole of the cross, so that the inclined surface loses its restriction on the tooth pattern and the tooth ring. At this time, a reset spring and an outward push spring will release the accumulated mechanical power. The outward push spring releases the mechanical power to directly push the grinding plate to fit closely to the inner wall of the pipe, and the reset spring releases the power to force the tooth ring to rotate.

Description

Technical Field

[0001] The invention relates to the technical field of cast iron processing equipment, in particular to a grey cast iron processing auxiliary device. Background Art

[0002] Gray cast iron is the most widely used type of cast iron. It is a cast iron with a large amount of flake graphite dispersed in the pearlite (or ferrite) matrix. Slow cooling during pouring can promote graphitization to obtain gray cast iron. It is distinguished from white cast iron by its gray-black fracture. Gray cast iron is generally classified as a brittle material, but it still has a certain amount of deformation work absorbed by external forces and exhibits a certain toughness. Its carbon content is generally 2.8%-4.0%. Due to its good pouring performance, it is widely used in castings with more complex structures, and even for pouring pressurized containers. Gray cast iron products include manhole covers, water filters, valves and other products.

[0003] Among them, after the water filter pipe is processed, it is often necessary to grind and polish it to prevent rust from appearing inside the water pipe. However, due to the narrow inner wall diameter of the pipe, it is difficult for workers to grind the deeper parts of the pipe. In order to improve the grinding efficiency of the equipment, the following solutions are proposed to address the above problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a gray cast iron processing auxiliary device, including a grinding mechanism, the grinding mechanism also includes a motor, the inner wall of the motor is rotatably connected to a driving column, and the end of the driving column away from the motor is fixedly connected to a mounting plate;

[0005] The control mechanism includes a tooth pattern formed on the outer wall of the mounting plate, a reset spring fixedly connected to the inner wall of the mounting plate, a fixed column fixedly connected to one end of the reset spring away from the mounting plate, a limit frame fixedly connected to the inner wall of the mounting plate, and an inner wall of the through hole of the limit frame rotatably connected to the outer wall of the fixed column;

[0006] The driving mechanism includes a tilting gear 1 fixedly connected to the end of the driving column away from the mounting plate, a fixed square plate fixedly connected to the side wall of the motor, a rotating column 1 is rotatably connected to the top of the fixed square plate, a tilting gear 2 is fixedly connected to the top of the rotating column 1, and the side wall of the tilting gear 2 is meshed with the side wall of the tilting gear 1.

[0007] Preferably, the grinding mechanism also includes a sliding rod slidably connected to the inner wall of the mounting plate, the end of the sliding rod away from the mounting plate is fixedly connected to the grinding plate, the side wall of the grinding plate is fixedly connected to the inclined grinding plate, and the bottom of the grinding plate is fixedly connected to a sliding gear rod.

[0008] Preferably, the grinding mechanism also includes a gear ring rotatably connected to the inside of the mounting plate, the inner wall of the gear ring is fixedly connected to the outer wall of the fixed column, an arc panel is fixedly connected to the side wall of the motor, the end of the arc panel away from the motor is slidably connected to the side wall of the mounting plate, the output shaft of the motor is fixedly connected to a driving gear, and a plurality of outward push springs are fixedly connected to the side wall of the mounting plate, the ends of the plurality of outward push springs away from the mounting plate are fixedly connected to the outer wall of the grinding plate, and the characteristic of controlling the outward extension of the sliding gear rod by the rotation angle of the gear ring is utilized, so that when the grinding plate is working, the grinding plate contacts the rust spots of the pipeline and removes thinner rust marks. When the equipment contacts the thicker rust on the inner wall of the pipe, the inclined surface of the inclined grinding plate will first contact the rust and remove part of the rust. At this time, when the grinding plate and the inclined grinding plate contact the thick rust, the grinding plate will be blocked and a reaction force will be generated, forming a force that presses the grinding plate to reset. This force will be transmitted to the gear ring through the sliding gear rod, and the gear ring will be evenly dispersed to the remaining sliding gear rods, causing multiple grinding plates to shrink synchronously. When the grinding plate encounters large pieces of rust, it can shrink multiple grinding plates to ensure that the equipment remains unchanged at the center point, avoid large protrusions, cause the center of gravity of the equipment to shift, and affect the rust removal effect.

[0009] Preferably, the control mechanism also includes a cross fixedly connected to the side wall of the fixed column, a configuration slider is slidably connected to the inner wall of the cross, a rotating rod is slidably connected to the inner wall of the configuration slider, a sliding baffle is slidably connected to the inner wall of the through hole of the cross, and one side of the sliding baffle is provided with a slope. When the above-mentioned equipment is in operation, the rotation angle of the gear ring will control the extension degree of the sliding gear rod. After the cross is disconnected from the tooth pattern, the rotation angle of the gear ring will directly affect the extension length of several sliding gear rods, and the extension length of the sliding gear rod will simultaneously control the extension length of multiple grinding plates, so that the lengths of multiple grinding plates reaching the center of the equipment are equal. Through the application of the above-mentioned components, it is ensured that the center of the installation plate and the center of the pipeline are at the same horizontal position during the operation of the equipment, so as to avoid the deviation of the center of gravity of the rotation of the grinding mechanism due to different lengths of the sliding rods, which affects the grinding effect and ensures uniform cleaning of various positions inside the pipeline.

[0010] Preferably, the control mechanism also includes an inclined surface provided at the side wall of the sliding baffle, and a push spring is fixedly connected to the side wall of the sliding baffle, and one end of the push spring away from the inclined surface is fixedly connected to the side wall of the cross. Before using the device, the staff rotates the cross, and the cross controls the multiple sliding rods to contract through the gear ring. At this time, the reset spring and the push spring are affected by the rotation of the cross, which will accumulate mechanical power. Finally, the entire device is placed in the inner wall of the pipeline, and the power supply of the motor is turned on. The motor drives the driving column to rotate through the driving gear, and the driving column drives the mounting plate to rotate synchronously through the mounting plate. When the driving column reaches a certain speed, the mounting plate and the cross will generate centrifugal force, and the centrifugal force will drive the configuration The slider and the rotating rod move outward, forcing the rotating rod to contact the inclined surface of the inclined surface, and as the rotation speed continues to increase, the outward expansion force of the rotating rod continues to increase, and finally the rotating rod forces the inclined surface to move sideways along the through hole of the cross, so that the inclined surface loses its restriction on the tooth pattern and the gear ring. At this time, the reset spring and the push-out spring will release the accumulated mechanical power. The release of the mechanical power by the push-out spring will directly push the grinding plate close to the inner wall of the pipe, and the release of power by the reset spring will force the gear ring to rotate. The rotation of the gear ring will drive the sliding rod and the grinding plate to extend outward. Through the application of the above components, the grinding plate is made to be close to the inner wall of the pipe, and as the mounting plate rotates, the grinding plate will clean the inner wall of the pipe in an orderly manner.

[0011] Preferably, the driving mechanism further comprises a telescopic rod fixedly connected to the side wall of the fixed square plate, one end of the telescopic rod away from the fixed square plate is rotatably connected to a rotating column 2, and the top of the rotating column 2 is fixedly connected to a driving wheel.

[0012] Preferably, the driving mechanism also includes a slide rail fixedly connected to the side wall of the motor, a sliding turntable is slidably connected to the inner wall of the slide rail, a pulling spring is fixedly connected to the side wall of the sliding turntable, and one end of the pulling spring away from the sliding turntable is fixedly connected to the top of the slide rail.

[0013] Preferably, the driving mechanism also includes a transmission belt sleeved on the outer wall of the rotating column one, and the end of the transmission belt away from the rotating column one is rotatably connected to the outer wall of the rotating column two, and the bottom of the telescopic rod is fixedly connected with an extrusion spring. Utilizing the characteristic that the above-mentioned motor rotates through the driving column, a driving mechanism is arranged inside the device. When the driving column rotates, the driving column drives the other two inclined gears two to run synchronously through the inclined gear one, and the force of the rotation of the inclined gear two is transmitted to the rotating column two through the transmission belt, and the rotating column two drives the top driving wheel to rotate, wherein the telescopic rod is limited to the effect of the thrust of the extrusion spring. When the device is in use, the thrust of the extrusion spring will force the side wall of the driving wheel to be close to the inner wall of the pipe. When the inclined gear one rotates, Fig. 9The G and F of the middle drive wheels will provide a forward thrust, and the other two drive wheels have no power source. The four drive wheels are in contact with the inner wall of the pipe. While preventing the motor from rotating, the two powered drive wheels will drive the entire device to move along the inner wall of the pipe, thereby cleaning the inner wall deep inside the pipe.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention aims to solve the problem that the inside of the pipeline is difficult to clean. A grinding mechanism and a driving mechanism are arranged inside the device. Before using the device, the staff rotates the cross, and the cross controls the multiple sliding rods to contract through the gear ring. At this time, the return spring and the push-out spring are affected by the rotation of the cross, which will accumulate mechanical power. Finally, the whole device is placed on the inner wall of the pipeline, and the power supply of the motor is turned on. The motor drives the driving column to rotate through the driving gear, and the driving column drives the mounting plate to rotate synchronously through the mounting plate. When the driving column reaches a certain speed, the mounting plate and the cross will generate centrifugal force, which will drive the configuration slider and the rotating rod to move outward, forcing The rotating rod contacts the inclined surface of the inclined surface, and as the rotation speed continues to increase, the outward expansion force of the rotating rod continues to increase. Finally, the rotating rod forces the inclined surface to move sideways along the through hole of the cross, so that the inclined surface loses its restriction on the tooth pattern and the toothed ring. At this time, the reset spring and the push-out spring will release the accumulated mechanical power. The release of the mechanical power by the push-out spring will directly push the grinding plate close to the inner wall of the pipe, and the release of power by the reset spring will force the toothed ring to rotate. The rotation of the toothed ring will drive the sliding rod and the grinding plate to extend outward. Through the application of the above components, the grinding plate is made to be close to the inner wall of the pipe, and as the mounting plate rotates, the grinding plate will clean the inner wall of the pipe in an orderly manner.

[0016] (2) The present invention utilizes the characteristic that the motor rotates through the driving column, and a driving mechanism is arranged inside the device. When the driving column rotates, the driving column drives the other two inclined gears 2 to run synchronously through the inclined gear 1, and the force of the rotation of the inclined gear 2 is transmitted to the rotating column 2 through the transmission belt, and the rotating column 2 then drives the top driving wheel to rotate. Among them, the telescopic rod is limited to the effect of the thrust of the extrusion spring. When the device is in use, the thrust of the extrusion spring will force the side wall of the driving wheel to be close to the inner wall of the pipe. When the inclined gear 1 rotates, Fig. 9 The G and F of the middle drive wheels will provide a forward thrust, and the other two drive wheels have no power source. The four drive wheels are in contact with the inner wall of the pipe. While preventing the motor from rotating, the two powered drive wheels will drive the entire device to move along the inner wall of the pipe, thereby cleaning the inner wall deep inside the pipe.

[0017] (3) The present invention utilizes the characteristic that when the above-mentioned equipment is in operation, the rotation angle of the gear ring will control the extension length of the sliding gear rod. After the cross is disconnected from the tooth pattern, the rotation angle of the gear ring will directly affect the extension length of several sliding gear rods, and the extension length of the sliding gear rod will simultaneously control the extension length of multiple grinding plates, so that the lengths of multiple grinding plates reaching the center of the equipment are equal. Through the application of the above-mentioned components, it is ensured that the center of the installation plate and the center of the pipeline are at the same horizontal position during the operation of the equipment, avoiding the deviation of the center of gravity of the grinding mechanism due to different lengths of the sliding rods, which affects the grinding effect, and ensures uniform cleaning of various positions inside the pipeline. In addition, when the equipment is in use, the push spring pushes the grinding plate to move outward, so that the grinding plate is tightly attached to the inner wall of the pipeline, and the extrusion spring pushes the telescopic rod, forcing the driving wheel to extend outward and contact the inner wall of the pipeline. Through the push of the push spring and the extrusion spring, the driving wheel and the grinding plate are always in contact with the inner wall of the pipeline, so that the equipment can be used for rust removal on the inner wall of pipelines with different diameters.

[0018] (4) The present invention utilizes the characteristic of the rotation angle of the gear ring to control the extension of the sliding gear rod. When the grinding plate is working, the grinding plate contacts the rust spots of the pipe and removes the thinner rust. When the equipment contacts the thicker rust on the inner wall of the pipe, the inclined surface of the inclined grinding plate will first contact the rust and remove part of the rust. At this time, when the grinding plate and the inclined grinding plate contact the thick rust, the grinding plate will be blocked and a reaction force will be generated, forming a force to press the grinding plate to reset. This force will be transmitted to the gear ring through the sliding gear rod, and the gear ring will be evenly dispersed to the remaining sliding gear rods, so that multiple grinding plates will shrink synchronously. When the grinding plate encounters large pieces of rust, it can shrink multiple grinding plates to ensure that the equipment remains unchanged at the center point, avoid large protrusions, cause the center of gravity of the equipment to shift, and affect the rust removal effect.

[0036] The grinding mechanism 1 also includes a gear ring 108 rotatably connected to the inside of the mounting plate 103, the inner wall of the gear ring 108 is fixedly connected to the outer wall of the fixed column 202, an arc panel 109 is fixedly connected to the side wall of the motor 101, and the end of the arc panel 109 away from the motor 101 is slidably connected to the side wall of the mounting plate 103, the output shaft of the motor 101 is fixedly connected to a driving gear 110, and a plurality of outward push springs 111 are fixedly connected to the side wall of the mounting plate 103, and the ends of the plurality of outward push springs 111 away from the mounting plate 103 are fixedly connected to the outer wall of the grinding plate 105. The rotation angle of the gear ring 108 is used to control the extension degree of the sliding gear rod 107. When the grinding plate 105 is working, the grinding plate 105 is in contact with the rust point of the pipeline. When the equipment contacts the thicker rust on the inner wall of the pipe, the inclined surface of the inclined grinding plate 106 will first contact the rust and remove part of the rust. At this time, when the grinding plate 105 contacts the thick rust with the inclined grinding plate 106, the grinding plate 105 is blocked and a reaction force is generated, forming a force that presses the grinding plate 105 to reset. This force will be transmitted to the gear ring 108 through the sliding gear rod 107, and the gear ring 108 will be evenly dispersed to the remaining sliding gear rods 107, so that multiple grinding plates 105 will shrink synchronously. When the grinding plate 105 encounters large pieces of rust, it can shrink multiple grinding plates 105 to ensure that the equipment remains unchanged at the center point, avoid large protrusions, cause the center of gravity of the equipment to shift, and affect the rust removal effect.

[0037] For example 2, please refer to Figure 4 - Fig. 9 The present invention is a gray cast iron processing auxiliary device. On the basis of the first embodiment, the control mechanism 2 also includes a cross 204 fixedly connected to the side wall of the fixed column 202, a configuration slider 205 is slidably connected to the inner wall of the cross 204, a rotating rod 206 is slidably connected to the inner wall of the configuration slider 205, a sliding baffle 207 is slidably connected to the inner wall of the through hole of the cross 204, and a slope is provided on one side of the sliding baffle 207. When the above device is operated, the rotation angle of the gear ring 108 will control the extension degree of the sliding gear rod 107. In the cross 20 After disconnecting from the tooth pattern 210, the rotation angle of the tooth ring 108 will directly affect the extension lengths of the plurality of sliding tooth rods 107, and the extension lengths of the sliding tooth rods 107 will simultaneously control the extension lengths of the plurality of grinding plates 105, so that the lengths of the plurality of grinding plates 105 reaching the center of the device are equal. By applying the above components, it is ensured that the center of the mounting plate 103 and the center of the pipeline are at the same horizontal position during the operation of the device, avoiding the deviation of the center of gravity of the grinding mechanism 1 due to the different lengths of the sliding rods 104, which affects the grinding effect, and ensures uniform cleaning of each position inside the pipeline.

[0038] The control mechanism 2 also includes an inclined surface 208 opened on the side wall of the sliding baffle 207, and a push spring 209 is fixedly connected to the side wall of the sliding baffle 207. The end of the push spring 209 away from the inclined surface 208 is fixedly connected to the side wall of the cross 204. Before using the device, the staff rotates the cross 204, and the cross 204 controls the multiple sliding rods 104 to contract through the gear ring 108. At this time, the return spring 201 and the push spring 111 are affected by the rotation of the cross 204, and mechanical power will be accumulated. Finally, the entire device is placed in the inner wall of the pipeline, and the power supply of the motor 101 is turned on. The motor 101 drives the driving column 102 to rotate through the driving gear 110, and the driving column 102 drives the mounting plate 103 to rotate synchronously through the mounting plate 103. When the driving column 102 reaches a certain speed, the mounting plate 103 and the cross 204 will generate centrifugal force, and the centrifugal force will drive the configuration The slider 205 and the rotating rod 206 move outward, forcing the rotating rod 206 to contact the inclined surface of the inclined surface 208, and as the rotation speed continues to increase, the force of the rotating rod 206 to expand outward continues to increase, and finally the rotating rod 206 forces the inclined surface 208 to move sideways along the through hole of the cross 204, so that the inclined surface 208 loses the restriction on the tooth pattern 210 and the toothed ring 108, at this time the reset spring 201 and the outward push spring 111 will release the accumulated mechanical power, the outward push spring 111 releases the mechanical power and will directly push the grinding plate 105 to fit closely to the inner wall of the pipe, and the reset spring 201 releases the power and will force the toothed ring 108 to rotate, and the rotation of the toothed ring 108 will drive the sliding rod 104 and the grinding plate 105 to extend outward, through the application of the above components, the grinding plate 105 is made to fit closely to the inner wall of the pipe, and as the mounting plate 103 rotates, the grinding plate 105 will clean the inner wall of the pipe in an orderly manner.

[0039] The driving mechanism 3 further comprises a telescopic rod 305 fixedly connected to the side wall of the fixed square plate 302 , and one end of the telescopic rod 305 away from the fixed square plate 302 is rotatably connected to a second rotating column 306 , and a driving wheel 307 is fixedly connected to the top of the second rotating column 306 .

[0040] The driving mechanism 3 also includes a slide rail 308 fixedly connected to the side wall of the motor 101, a slide turntable 309 is slidably connected to the inner wall of the slide rail 308, a pull spring 310 is fixedly connected to the side wall of the slide turntable 309, and one end of the pull spring 310 away from the slide turntable 309 is fixedly connected to the top of the slide rail 308.

[0041] The driving mechanism 3 also includes a transmission belt 311 sleeved on the outer wall of the rotating column 1 303, and the end of the transmission belt 311 away from the rotating column 1 303 is rotatably connected to the outer wall of the rotating column 2 306, and the bottom of the telescopic rod 305 is fixedly connected with an extrusion spring 312. Utilizing the characteristic that the motor 101 rotates through the driving column 102, a driving mechanism 3 is arranged inside the device. When the driving column 102 rotates, the driving column 102 drives the other two inclined gears 2 304 to run synchronously through the inclined gear 1 301, and the force of the rotation of the inclined gear 2 304 is transmitted to the rotating column 2 306 through the transmission belt 311, and the rotating column 2 306 drives the top driving wheel 307 to rotate, wherein the telescopic rod 305 is limited by the influence of the thrust of the extrusion spring 312. When the device is in use, the thrust of the extrusion spring 312 will force the side wall of the driving wheel 307 to be close to the inner wall of the pipe. When the inclined gear 1 301 rotates, Fig. 9 G and F of the middle driving wheel 307 will provide a forward thrust, and the other two driving wheels 307 have no power source. The four driving wheels 307 are in contact with the inner wall of the pipe. While preventing the motor 101 from rotating, the two powered driving wheels 307 will drive the entire device to move along the inner wall of the pipe, thereby cleaning the inner wall deep inside the pipe.

[0042] A specific application of this embodiment is: before using the device, the staff rotates the cross 204, and the cross 204 controls the multiple sliding rods 104 to contract through the gear ring 108. At this time, the return spring 201 and the push-out spring 111 are affected by the rotation of the cross 204, and mechanical power is accumulated. Finally, the whole device is placed in the inner wall of the pipeline, and the power of the motor 101 is turned on. The motor 101 drives the driving column 102 to rotate through the driving gear 110, and the driving column 102 drives the mounting plate 103 to rotate synchronously through the mounting plate 103. When the driving column 102 reaches a certain speed, the mounting plate 103 and the cross 204 will generate centrifugal force, and the centrifugal force will drive the configuration slider 205 and the rotating rod 206 to move outward, forcing the rotating rod 206 and the inclined surface 208 to rotate. The rotating rod 206 will contact the toothed plate 105, and as the rotation speed continues to increase, the force of the rotating rod 206 to expand outwards continues to increase. Finally, the rotating rod 206 forces the inclined surface 208 to move sideways along the through hole of the cross 204, so that the inclined surface 208 loses the restriction on the tooth pattern 210 and the toothed ring 108. At this time, the reset spring 201 and the push-out spring 111 will release the accumulated mechanical power. The push-out spring 111 releases the mechanical power and directly pushes the grinding plate 105 to fit closely to the inner wall of the pipe. The release of the power by the reset spring 201 will force the toothed ring 108 to rotate. The rotation of the toothed ring 108 will drive the sliding rod 104 and the grinding plate 105 to extend outwards. Through the application of the above components, the grinding plate 105 is closely attached to the inner wall of the pipe, and as the mounting plate 103 rotates, the grinding plate 105 will clean the inner wall of the pipe in an orderly manner.

[0043] Taking advantage of the characteristic that the motor 101 rotates through the driving column 102, a driving mechanism 3 is provided inside the device. When the driving column 102 rotates, the driving column 102 drives the other two inclined gears 2 304 to run synchronously through the inclined gear 1 301, and the rotating force of the inclined gear 2 304 is transmitted to the rotating column 2 306 through the transmission belt 311, and the rotating column 2 306 drives the top driving wheel 307 to rotate, wherein the telescopic rod 305 is limited to the effect of the thrust of the squeezing spring 312. When the device is in use, the thrust of the squeezing spring 312 will force the side wall of the driving wheel 307 to be close to the inner wall of the pipe. When the inclined gear 1 301 rotates, Fig. 9 The G and F of the middle driving wheel 307 will provide a forward thrust, and the other two driving wheels 307 have no power source, while the four driving wheels 307 are in contact with the inner wall of the pipeline. While preventing the motor 101 from rotating, the two driving wheels 307 with power will drive the entire device to move along the inner wall of the pipeline to achieve cleaning of the inner wall deep in the pipeline. When the above-mentioned device is in operation, the rotation angle of the gear ring 108 will control the extension of the sliding gear rod 107. After the cross 204 is disconnected from the tooth pattern 210, the rotation angle of the gear ring 108 will directly affect the extension length of several sliding gear rods 107, and the extension length of the sliding gear rod 107 will simultaneously control the extension length of multiple grinding plates 105, so that multiple grinding plates 105 reach the device circle. The lengths of the centers are equal. Through the application of the above-mentioned components, it is ensured that the center of the circle of the mounting plate 103 and the center of the pipeline are at the same horizontal position during operation of the equipment, so as to avoid the different lengths of the sliding rod 104, the deviation of the center of gravity of the rotation of the grinding mechanism 1, which affects the grinding effect and ensures uniform cleaning of various positions inside the pipeline. In addition, when the equipment is in use, the outward push spring 111 pushes the grinding plate 105 to move outward, so that the grinding plate 105 is close to the inner wall of the pipeline, and the extrusion spring 312 pushes the telescopic rod 305, forcing the driving wheel 307 to extend outward and contact the inner wall of the pipeline. Through the push of the outward push spring 111 and the extrusion spring 312, the driving wheel 307 and the grinding plate 105 are always in contact with the inner wall of the pipeline, so that the equipment can be used for rust removal on the inner wall of pipelines with different diameters.

[0044] By utilizing the characteristic that the rotation angle of the gear ring 108 controls the extension degree of the sliding gear rod 107, when the grinding plate 105 is working, the grinding plate 105 contacts the rust spots of the pipe and removes thinner rust. When the equipment contacts the thicker rust on the inner wall of the pipe, the inclined surface of the inclined grinding plate 106 will first contact the rust and remove part of the rust. At this time, when the grinding plate 105 and the inclined grinding plate 106 contact the thick rust, the grinding plate 105 is blocked and a reaction force is generated, forming a force that presses the grinding plate 105 to reset. This force will be transmitted to the gear ring 108 through the sliding gear rod 107, and the gear ring 108 will be evenly dispersed to the remaining sliding gear rods 107, so that multiple grinding plates 105 will shrink synchronously. When the grinding plate 105 encounters large pieces of rust, it can shrink multiple grinding plates 105 to ensure that the equipment remains unchanged at the center point, avoid large protrusions, cause the center of gravity of the equipment to shift, and affect the rust removal effect.
