Description

Technical Field

[0001] This invention relates to the field of grinding and rust removal technology, and in particular to a device for grinding and rust removal of pipes. Background Technology

[0002] Pipelines are devices made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. They are widely used in building construction, water and electricity projects, and daily life. However, after prolonged use or storage, moisture molecules in the air can cause rust to form on the outer surface of pipes. If not addressed promptly, this can affect the lifespan of the pipes. Traditional rust removal methods often rely on manual labor, significantly increasing the workload for workers. This is not only time-consuming and labor-intensive but also ineffective in completely removing rust.

[0003] Pipeline installation is a routine installation project in industrial installation. Generally speaking, pipelines are prone to corrosion, and rust removal is necessary to ensure project quality. Traditionally, this is done manually, but due to limitations in pipeline inner diameter and length, the process is difficult, inefficient, and produces poor rust removal quality.

[0004] When removing rust from pipes, it is necessary to thoroughly clean the rust from both the inner and outer walls of the pipes, and to polish the inner wall completely to ensure the service life of the pipes. The pipes should also be kept clamped and operated at low speed to ensure the stability of the pipes and the thoroughness of the cleaning during the rust removal process. Summary of the Invention

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a pipe grinding and rust removal device, which includes a grinding unit 100 and a fixing unit 200. Through the cooperation of the grinding unit 100 and the fixing unit 200, the driving component 101 drives the grinding component 102 to grind and remove rust from the inner wall of the pipe, and drives the spraying component 103 to spray a small amount of rust remover to ensure thorough rust removal from the pipe. The fixing rust removal component 104 slowly advances to grind the outer wall of the pipe. The rotating fixing component 201 clamps and fixes the pipe and drives the pipe to rotate at a uniform speed to ensure uniform grinding. The auxiliary rotation support component 202 supports the pipe and assists the rotation of the pipe to ensure the stability of the pipe rotation.

[0035] Specifically, the grinding unit 100 includes a drive assembly 101, a grinding assembly 102 disposed on one side of the drive assembly 101, a spraying assembly 103 disposed on one side of the grinding assembly 102, and a fixed rust removal assembly 104 disposed on the top of the grinding assembly 102.

[0036] The fixing unit 200 includes a rotating fixing component 201 and two sets of auxiliary rotating support components 202 disposed on one side of the rotating fixing component 201.

[0037] In summary, this invention, through the cooperation of a grinding unit and a fixing unit, supports the pipeline and assists in its rotation to ensure stability during rotation. It clamps the pipeline and drives it to rotate stably, resulting in more uniform grinding. The grinding component grinds and removes rust from the inner wall of the pipeline at low speeds, while the spraying component sprays a small amount of rust remover under centrifugal force to avoid waste. The rotating fixing component then makes close contact with the pipeline and moves slowly forward to grind and remove rust from the outer wall. At high speeds, under centrifugal force, the polishing plate contacts and polishes the inner wall of the pipeline, ensuring the inner surface of the pipeline remains in a long-term passive state and significantly improving its corrosion resistance.

[0038] Example 2

[0039] Reference Figures 1-10This is the second embodiment of the present invention. This embodiment provides a pipe grinding and rust removal device, which includes a grinding unit 100 and a fixing unit 200. Through the cooperation of the grinding unit 100 and the fixing unit 200, the driving component 101 drives the grinding component 102 to grind and remove rust from the inner wall of the pipe, and drives the spraying component 103 to spray a small amount of rust remover to ensure thorough rust removal from the pipe. The fixing rust removal component 104 slowly advances to grind the outer wall of the pipe. The rotating fixing component 201 clamps and fixes the pipe and drives the pipe to rotate at a uniform speed to ensure uniform grinding. The auxiliary rotation support component 202 supports the pipe and assists the rotation of the pipe to ensure the stability of the pipe rotation.

[0040] Specifically, the grinding unit 100 includes a drive assembly 101, a grinding assembly 102 disposed on one side of the drive assembly 101, a spraying assembly 103 disposed on one side of the grinding assembly 102, and a fixed rust removal assembly 104 disposed on the top of the grinding assembly 102.

[0041] The fixing unit 200 includes a rotating fixing component 201 and two sets of auxiliary rotating support components 202 disposed on one side of the rotating fixing component 201.

[0042] Furthermore, the drive assembly 101 includes a support column 101a, a cylinder 101b disposed on the top of the support column 101a, a hydraulic rod 101c movably connected to the cylinder 101b, a sliding plate 101d disposed on one side of the hydraulic rod 101c, a sliding groove 101e disposed on the bottom of the sliding plate 101d, a drive motor 101f fixedly connected to one side of the sliding plate 101d, a rotating rod 101g disposed on one side of the drive motor 101f, a first belt drive ring 101h disposed on one side of the rotating rod 101g, and a transmission belt 101i disposed within the first belt drive ring 101h.

[0043] Furthermore, the polishing assembly 102 includes a polishing roller 102a, a polishing surface 102b disposed on one side of the polishing roller 102a, three sets of telescopic grooves 102c disposed on one side of the polishing roller 102a, two sets of telescopic sleeves 102d fixedly connected to the bottom of the telescopic grooves 102c, a telescopic rod 102e movably connected to the top of the telescopic sleeves 102d, a polishing plate 102f fixedly connected to the top of the telescopic rod 102e, and a first telescopic spring 102g fixedly connected at both ends to the top of the telescopic rod 102e and the bottom of the polishing plate 102f, respectively.

[0044] Furthermore, the spraying assembly 103 includes a storage tank 103a, a rust remover storage space 103b disposed inside the storage tank 103a, a telescopic cylinder 103c fixedly connected to the bottom of the rust remover storage space 103b, a telescopic column 103d movably connected to the top of the telescopic cylinder 103c, a sealing plate 103e fixedly connected to the top of the telescopic column 103d, a spraying plate 103f disposed at the bottom of the sealing plate 103e, a plurality of spray holes 103g disposed on one side of the spraying plate 103f, and a second telescopic spring 103h fixedly connected at both ends to the top of the telescopic cylinder 103c and the bottom of the sealing plate 103e, respectively.

[0045] Preferably, the drive motor 101f is started in low-speed operation mode, driving the rotating rod 101g to rotate. The grinding roller 102a rotates accordingly. The cylinder 101b is activated to push the hydraulic rod 101c forward, causing the sliding plate 101d to move forward within the sliding groove 101e. This causes the grinding roller 102a to move forward and contact the inner wall of the pipe, grinding the inner wall. During the rotation of the storage tank 103a, the telescopic column 103d, which is movably connected to the top of the telescopic cylinder 103c, pulls the second telescopic spring 103h forward under the action of centrifugal force, pushing the storage tank 103a forward. The sealing plate 103e moves forward, exposing the bottom spray plate 103f, thus releasing the sealing setting. The rust remover in the storage space 103b inside the storage box 103a is sprayed in small amounts and evenly onto the inner wall of the pipe through several sets of spray holes 103g on the spray plate 103f under the action of centrifugal force of rotation, making the grinding smoother and the rust removal more thorough. Under the action of gravity, the rust remover will slowly accumulate at the bottom of the pipe, so that there will be more rust remover on the contact surface between the grinding roller 102a and the pipe grinding, which can better clean the rust on the inner wall of the pipe.

[0046] In the high-speed operation mode of the drive motor 101f, the rotating rod 101g is driven to rotate at high speed, and the grinding roller 102a follows the high-speed rotation. The start cylinder 101b pushes the hydraulic rod 101c forward, causing the sliding plate 101d to move forward in the sliding groove 101e, and the grinding roller 102a follows forward, contacting the inner wall of the pipe. The centrifugal force under high-speed rotation is greater than the pull of the first telescopic spring 102g on the polishing plate 102f, causing the polishing plate 102f to pull the first telescopic spring 102g to drive the telescopic rod 102e to move outward. Under the restriction of the telescopic rod 102e, the polishing plate 102f can only move to slightly higher than the grinding surface 102b. Under the influence of gravity, the height is lowest when the top of the grinding roller 102a is perpendicular to the ground, and the height is highest when the bottom of the grinding roller 102a is perpendicular to the ground, making full contact with the inner wall of the pipe and polishing the inner wall of the pipe.

[0047] Furthermore, the fixed rust removal assembly 104 includes a C-shaped fixing plate 104a, a driven rod 104b rotatably connected to one side of the C-shaped fixing plate 104a, a second belt drive ring 104c disposed on one side of the driven rod 104b, three sets of sliding columns 104d fixedly connected to the bottom of the second belt drive ring 104c, three sets of sliding grooves 104e disposed on one side of the driven rod 104b, a threaded rod 104f disposed at one end of the driven rod 104b, a drive rod 104g threadedly connected to the threaded rod 104f, a connecting rod 104h disposed at one end of the driven rod 104b, a first fixing plate 104i fixedly connected to the middle of the connecting rod 104h, a sliding rod 104j disposed at one end of the connecting rod 104h, a second fixing plate 104k fixedly connected to one end of the sliding rod 104j, and a clamping member 104l fixedly connected to the bottom of the drive rod 104g.

[0048] Preferably, driven by the drive motor 101f, the rotating rod 101g rotates, and the first belt drive ring 101h rotates with the rotating rod 101g, causing the transmission belt 101i set in the first belt drive ring 101h to rotate synchronously, pulling the second belt drive ring 104c to rotate synchronously, causing the driven rod 104b to rotate as well, so that the drive rod 104g moves slowly forward under the threaded connection with the threaded rod 104f. The sliding rod 104j connected to the other end of the drive rod 104g has a smooth surface, ensuring that the drive rod 104g does not rotate with the driven rod 104b, but moves slowly on the threaded rod 104f, causing the clamping member 104l fixedly connected at the bottom to move, and the push-pull rod Driven by 104l-2, the first clamping block 104l-4 and the second clamping block 104l-6 come into contact with the surface of the pipe, pushing the limiting spring 104l-8, which is fixedly connected to one end of the first spring fixing post 104l-5 and the second spring fixing post 104l-7 respectively, to open. The retraction force of the limiting spring 104l-8 ensures that the first clamping block 104l-4 and the second clamping block 104l-6 are in close contact with the surface of the pipe, providing double clamping to the pipe and ensuring stability during grinding. The friction surfaces of the first clamping block 104l-4 and the second clamping block 104l-6 grind the surface of the pipe as the pipe rotates, following the slow movement of the drive rod 104g.

[0049] Furthermore, the rotating fixing assembly 201 includes a fixed base 201a, a motor 201b disposed on the top of the fixed base 201a, a rotating connecting column 201c rotatably connected to one side of the motor 201b, a clamping turntable 201d fixedly connected to one end of the rotating connecting column 201c, three sets of clamping grooves 201e disposed on one side of the clamping turntable 201d, a clamping spring 201f fixedly connected to one side of the clamping groove 201e, a clamping rod 201g fixedly connected to one end of the clamping spring 201f, and a clamping plate 201h fixedly connected to the top of the clamping rod 201g.

[0050] Furthermore, the auxiliary rotation support assembly 202 includes a support base 202a, two sets of movable grooves 202b disposed on the top of the support base 202a, a spring 202c fixedly connected to one end of the movable groove 202b, a T-shaped movable column 202d fixedly connected to one end of the spring 202c, two sets of fixed connecting plates 202e disposed on the top of the T-shaped movable column 202d, a fixed shaft 202f whose two ends are respectively fixedly connected to one side of the two sets of fixed connecting plates 202e, and a support wheel 202g disposed in the middle of the fixed shaft 202f.

[0051] Furthermore, the clamping member 104l includes a fixing block 104l-1 fixedly connected to the bottom of the drive rod 104g, a push-pull rod 104l-2 disposed at the bottom of the fixing block 104l-1, a fixing rod 104l-3 disposed on one side of the push-pull rod 104l-2, a first clamping block 104l-4 rotatably connected to the fixing rod 104l-3, a first spring fixing post 104l-5 disposed on one side of the first clamping block 104l-4, a second clamping block 104l-6 rotatably connected to the fixing rod 104l-3, a second spring fixing post 104l-7 disposed on one side of the second clamping block 104l-6, and a limiting spring 104l-8 whose two ends are respectively fixedly connected to one end of the first spring fixing post 104l-5 and one end of the second spring fixing post 104l-7.

[0052] Furthermore, the sliding rod 104j is configured as a smooth surface, and both the first belt drive ring 101h and the second belt drive ring 104c are adapted to the transmission belt 101i.

[0053] Furthermore, the polishing plate 102f is lower than the height of the grinding surface 102b, and the maximum length of the telescopic rod 102e pushes the polishing plate 102f higher than the height of the grinding surface 102b.

[0054] It should be noted that when the cylinder 101b pushes the hydraulic rod 101c, the hydraulic rod 101c contacts the sliding plate 101d, pushing the sliding plate 101d to slide in the sliding groove 101e, which drives the rotating rod 101g to move forward. The first belt drive ring 101h moves forward accordingly. Under the pull of the transmission belt 101i, the three sets of sliding columns 104d fixed at the bottom of the second belt drive ring 104c move forward in the three sets of sliding grooves 104e, avoiding the clamping part 104l from losing the grinding target and causing failure due to the pulling of the driven rod 104b. When placing the pipe, first push open the clamping rod 201g on one side of the clamping turntable 201d, and place one end of the pipe in. Under the pull of the clamping spring 201f, the three sets of clamping rods 201g clamp one end of the pipe. Pull the T-shaped moving column 202d to move the spring 202c to one side, placing the pipe on the support wheel 202g. Release the pull on the T-shaped moving column 202d. The rebound force of the spring 202c pulls the T-shaped moving column 202d to move in the moving groove 202b and make close contact with the pipe surface, so that the four sets of support wheels 202g support the pipe. The motor 201b drives the clamping turntable 201d to rotate at a constant speed, so that the pipe clamped by the three sets of clamping rods 201g rotates with it. The support wheel 202g assists in rotating with the pipe, ensuring the stability of the pipe during rotation.

[0055] In use, this invention has a total of three usage processes. The first process involves placing the pipe to be polished. First, push open the clamping rods 201g on one side of the clamping turntable 201d, and place one end of the pipe inside. Under the pull of the clamping springs 201f, the three sets of clamping rods 201g clamp one end of the pipe. Pulling the T-shaped moving column 202d causes the spring 202c to move to one side, placing the pipe on the support wheels 202g. Then, release the pull on the T-shaped moving column 202d. The rebound force of the spring 202c pulls the T-shaped moving column 202d to move within the moving groove 202b, making close contact with the pipe surface. This allows the four sets of support wheels 202g to support the pipe. The motor 201b drives the clamping turntable 201d to rotate at a constant speed, causing the pipe clamped by the three sets of clamping rods 201g to rotate accordingly. The support wheels 202g assist in following the pipe's rotation, ensuring the stability of the pipe during rotation.

[0056] In the second usage process, the inner surface of the pipe is ground at low speed. The drive motor 101f is activated in low-speed mode, causing the rotating rod 101g to rotate. The grinding roller 102a rotates accordingly. The cylinder 101b is activated, pushing the hydraulic rod 101c forward, causing the sliding plate 101d to move forward within the sliding groove 101e. This allows the grinding roller 102a to advance and contact the inner wall of the pipe, grinding it. During rotation, the storage tank 103a, connected to the top of the telescopic cylinder 103c, uses the telescopic column 103d, pulled forward by centrifugal force, to activate the second telescopic spring. Spring 103h pushes sealing plate 103e forward, exposing spray plate 103f at the bottom, releasing the sealing setting. Rust remover in storage space 103b inside storage box 103a is sprayed in small amounts and evenly onto the inner wall of the pipe through several sets of spray holes 103g on spray plate 103f under the action of centrifugal force of rotation, making grinding smoother and rust removal more thorough. Under the action of gravity, rust remover will slowly accumulate at the bottom of the pipe, so that there is more rust remover on the contact surface between grinding roller 102a and pipe grinding, which can better clean the rust on the inner wall of the pipe.

[0057] The third process involves high-speed polishing of the inner surface of the pipe. In the high-speed operation mode of the drive motor 101f, the rotating rod 101g rotates at high speed, and the polishing roller 102a follows suit. The cylinder 101b is activated, causing the hydraulic rod 101c to push forward, moving the sliding plate 101d forward within the sliding groove 101e. This causes the polishing roller 102a to move forward and contact the inner wall of the pipe. The centrifugal force under high-speed rotation is greater than the tension of the first telescopic spring 102g on the polishing plate 102f, causing the polishing plate 102f to pull the first telescopic spring 102g, which in turn moves the telescopic rod 102e outward. Under the constraint of the telescopic rod 102e, the polishing plate 102f can only move slightly above the polishing surface 102b. Due to gravity, the height is lowest when the apex of the polishing roller 102a is perpendicular to the ground, and highest when the bottom point of the polishing roller 102a is perpendicular to the ground, ensuring full contact with the inner wall of the pipe and polishing the inner wall.

[0058] In the fourth usage process, the outer surface of the pipe is polished. Driven by the drive motor 101f, the rotating rod 101g rotates. The first belt drive ring 101h rotates with the rotating rod 101g, driving the transmission belt 101i set inside the first belt drive ring 101h to rotate synchronously. This pulls the second belt drive ring 104c to rotate synchronously, causing the driven rod 104b to rotate as well. The drive rod 104g moves slowly forward under the threaded connection with the threaded rod 104f. The sliding rod 104j connected to the other end of the drive rod 104g has a smooth surface, ensuring that the drive rod 104g does not rotate with the driven rod 104b. It moves slowly on the threaded rod 104f, driving the clamping piece 104 fixedly connected at the bottom. As the push rod 104l-2 moves, the first clamping block 104l-4 and the second clamping block 104l-6 come into contact with the surface of the pipe, pushing the limiting spring 104l-8, which is fixedly connected to one end of the first spring fixing post 104l-5 and the other end of the second spring fixing post 104l-7, to open. The retraction force of the limiting spring 104l-8 ensures that the first clamping block 104l-4 and the second clamping block 104l-6 are in close contact with the surface of the pipe, providing double clamping for the pipe and ensuring stability during grinding. The friction surfaces of the first clamping block 104l-4 and the second clamping block 104l-6 grind the surface of the pipe as it slowly moves with the drive rod 104g and rotates.

[0059] In summary, this invention, through the cooperation of a grinding unit and a fixing unit, supports the pipeline and assists in its rotation to ensure stability during rotation. It clamps the pipeline and drives it to rotate stably, resulting in more uniform grinding. The grinding component grinds and removes rust from the inner wall of the pipeline at low speeds, while the spraying component sprays a small amount of rust remover under centrifugal force to avoid waste. The rotating fixing component then makes close contact with the pipeline and moves slowly forward to grind and remove rust from the outer wall. At high speeds, under centrifugal force, the polishing plate contacts and polishes the inner wall of the pipeline, ensuring the inner surface of the pipeline remains in a long-term passive state and significantly improving its corrosion resistance.
