[0001] The present invention relates to the technical field of steel polishing equipment, in particular to a steel polishing device for construction engineering and a use method thereof. Background Art

[0002] In industrial production and the construction industry, the demand for steel is huge. Due to the requirements of process and quality, the outer surface of the steel needs to be ground and polished when processing steel. Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media.

[0003] When polishing construction steel, it is usually necessary to clamp and fix the construction steel first, and then polish the construction steel by moving the grinding wheel. However, when clamping and fixing the construction steel, the operation of fixing one end of the construction steel is relatively cumbersome, and since it is clamped and fixed at one end, it is necessary to change the direction and perform a second polishing on the clamping position during the polishing process, which affects the continuity of the polishing. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a steel polishing device for construction engineering, comprising a support plate, a support column fixedly connected to the bottom of the support plate, a slide rail fixedly connected to the top of the support plate, a fixed plate fixedly connected to the top of the support plate, and an anti-tilt assembly rotatably connected to the inner wall of the support plate;

[0005] A sliding polishing mechanism, comprising a steel pipe, an electric telescopic rod for rotating and polishing the steel pipe, a sliding bracket, a motor, a grinding wheel, a protective cover, and an automatic clamping mechanism for limiting and clamping the steel pipe;

[0006] The outer wall of the electric telescopic rod is fixedly connected to the top of the support plate, the outer wall of the sliding bracket is slidably connected to the outer wall of the slide rail, the outer wall of the sliding bracket is fixedly connected to the outer wall of the electric telescopic rod, the outer wall of the motor is fixedly connected to the inner wall of the sliding bracket, the outer wall of the grinding wheel is fixedly connected to the outer wall of the motor, the outer wall of the protective cover is fixedly connected to the outer wall of the sliding bracket, and the outer wall of the steel pipe is rotatably connected to the outer wall of the grinding wheel.

[0007] Preferably, the automatic clamping mechanism includes an arc-shaped bracket 1 that is slidably connected to the inner wall of the support plate, a roller is rotatably connected to the inner wall of the arc-shaped bracket 1, a spring plate is fixedly connected to the bottom of the arc-shaped bracket 1, and a hydraulic pipe 1 is fixedly connected to the inner wall of the support plate. After the steel pipe is placed on the arc-shaped bracket 1, the arc-shaped bracket 1 will move downward due to the gravity of the steel pipe. When the arc-shaped bracket 1 moves downward, the spring plate is synchronously driven to move. When the spring plate moves, the hydraulic oil at its bottom will be squeezed, causing the hydraulic oil to enter the hydraulic pipe 1.

[0008] Preferably, the automatic clamping mechanism also includes a hydraulic rod 1 fixedly connected to the inner wall of the support plate, the top of the hydraulic rod 1 is fixedly connected to a rotating shaft 1, the outer wall of the rotating shaft 1 is rotatably connected to an arc-shaped bracket 2, the outer wall of the arc-shaped bracket 2 is fixedly connected to a rotating shaft 2, the outer wall of the rotating shaft 2 is rotatably connected to the inner wall of the arc-shaped bracket 1, and a cleaning limiting assembly is fixedly connected to the outer wall of the roller. The hydraulic oil enters the hydraulic rod 1 through the hydraulic pipe 1, allowing the hydraulic rod 1 to extend upward. When the hydraulic rod 1 extends upward, the rotating shaft 1 pushes the arc-shaped bracket 2, causing the arc-shaped bracket 2 to rotate around the rotating shaft 2 as the axis, so that the arc-shaped bracket 1 and the arc-shaped bracket 2 can form an embracing state around the steel pipe.

[0009] Preferably, the automatic clamping mechanism also includes a hydraulic pipe 2 fixedly connected to the inner wall of the support plate, a hydraulic rod 2 fixedly connected to the top of the support plate, a sliding block slidably connected to the inner wall of the support plate, the outer wall of the sliding block is fixedly connected to the outer wall of the hydraulic rod 2, and the top of the sliding block is fixedly connected to a guide wheel. Taking advantage of the characteristic that the arc bracket 1 will be pressed down after the steel pipe is placed on the arc bracket 1, two spring plates are provided. After the steel pipe is placed on the arc bracket 1, the arc bracket 1 will move downward under the gravity of the steel pipe. When the arc bracket 1 moves downward, the spring plate is driven to move synchronously. When the spring plate moves, it squeezes the hydraulic oil at its bottom, so that the hydraulic oil enters the hydraulic rod 1 through the hydraulic pipe 1, allowing the hydraulic rod 1 to extend upward. When the hydraulic rod 1 extends upward, the arc bracket 2 is pushed by the rotating shaft 1, so that the arc bracket 2 can rotate The second shaft rotates about the axis so that the arc bracket 1 and the arc bracket 2 can form an embracing state with the steel pipe. At the same time, the hydraulic oil under the spring plate will also enter the hydraulic rod 2 through the hydraulic pipe 2, thereby pushing the sliding block and the guide wheel to move, so that the guide wheel contacts and squeezes the steel pipe. When the steel pipe is lifted up and taken out, the spring plate rebounds to make the hydraulic oil flow back, and the hydraulic rod 1 and the hydraulic rod 2 retract, so that the arc bracket 2 and the guide wheel are reset. Through the operation of the above components, the steel pipe can be automatically clamped when it is placed, avoiding the tedious operation of adjusting the clamping before polishing. At the same time, through the embracing clamping of the arc bracket 1 and the arc bracket 2, the grinding wheel can perform continuous polishing from beginning to end when polishing the steel pipe, avoiding the need to change one end to continue polishing during polishing, which affects the continuity of polishing and work efficiency.

[0010] Preferably, the anti-tilt assembly includes a rotating rod rotatably connected to the inner wall of the support plate, a half gear is fixedly connected to the outer wall of the rotating rod, a connecting rod 1 is fixedly connected to the outer wall of the half gear, the outer wall of the connecting rod 1 is fixedly connected to a rotating shaft 3, the outer wall of the rotating shaft 3 is rotatably connected to the inner wall of the arc-shaped bracket 1, and utilizing the above-mentioned characteristic that the arc-shaped bracket 1 will be pressed down, two connecting rods 1 are provided, and when the arc-shaped bracket 1 is lowered by the gravity of the steel pipe, the connecting rod 1 is synchronously driven by the rotating shaft 3 to rotate downward with the rotating rod as the axis, and when the connecting rod 1 rotates downward, it drives the rotating rod and the half gear to rotate together, and when the half gear rotates, it synchronously drives the other end When the half gear at one end rotates, when the half gear at the other end rotates, it will drive the connecting rod 1 at the other end to rotate downward with the rotating rod at the other end as the axis, and then drive the arc-shaped bracket 1 at the other end to move downward through the rotating shaft 3 at the other end. Through the operation of the above components, when the weight at both ends of the steel pipe is unequal and the weight on one side is heavier, the arc-shaped bracket 1 on both sides can be lowered to the same position through the half gear and the connecting rod 1, so that the steel pipe can be kept in a relatively horizontal state, so as to facilitate its subsequent polishing and avoid the steel pipe from tilting during polishing, so that the contact pressure between the grinding wheel and the steel pipe at different positions is different, thereby affecting the polishing of the steel pipe.

[0011] Preferably, the cleaning limiting assembly includes a rotating block fixedly connected to the outer wall of the roller, a counterweight block is slidably connected to the inner wall of the rotating block, an arc spring plate 1 is slidably connected to the inner wall of the arc bracket 1, a connecting rod 2 is fixedly connected to the outer wall of the arc spring plate 1, and the outer wall of the connecting rod 2 is slidably connected to the inner wall of the arc bracket 1. When the steel pipe rotates rapidly, it will drive the roller and the rotating block to rotate together. When the rotating block rotates, the centrifugal force will cause the counterweight block to move outward. When the counterweight block moves outward, it will push the arc spring plate 1 to move outward synchronously.

[0012] Preferably, the cleaning limiting assembly also includes a cleaning scraper fixedly connected to the outer wall of the connecting rod 2, an arc-shaped slide buckle is slidably connected to the inner wall of the arc-shaped spring plate 1, and an arc-shaped spring plate 2 is slidably connected to the inner wall of the arc-shaped bracket 1. The outer wall of the arc-shaped spring plate 2 is fixedly connected to a piston plate, and the outer wall of the piston plate is slidably connected to the inner wall of the arc-shaped bracket 1. When the counterweight block moves outward, it will push the arc-shaped spring plate 1 and the arc-shaped spring plate 2 to move outward synchronously. When the arc-shaped spring plate 1 moves outward, the cleaning scraper is driven to move outward together through the connecting rod 2, so that the cleaning scraper and the roller change from contact to non-contact. When the arc-shaped spring plate 2 moves, it will push the piston plate to move outward.

[0013] Preferably, the cleaning limiting assembly also includes a connecting tube fixedly connected to the inner wall of the arc-shaped bracket 1, a fixed block fixedly connected to the inner wall of the arc-shaped bracket 1, the inner wall of the fixed block is fixedly connected to the outer wall of the connecting tube, and the inner wall of the fixed block is fixedly connected to the arc tube. When the steel tube is polished, the steel tube rotates rapidly. When the steel tube rotates rapidly, it drives the roller and the rotating block to rotate together. When the rotating block rotates, the centrifugal force causes the counterweight block to move outward. When the counterweight block moves outward, it pushes the arc spring plate 1 and the arc spring plate 2 to move outward synchronously. When the arc spring plate 1 moves outward, the cleaning scraper is driven to move together through the connecting rod 2. The cleaning scraper moves outward, so that the contact with the roller changes to non-contact. After the polishing of the steel pipe is completed, the rotation speed of the steel pipe will gradually decrease, and the rotation speed of the roller and the rotating block will be reduced synchronously. At this time, the centrifugal force is reduced, and under the action of the arc spring plate 1, the counterweight block begins to retract. At the same time, the cleaning scraper will continue to contact the roller, so that the cleaning scraper can scrape and clean the surface of the roller, avoiding the debris generated during the polishing of the steel pipe from sticking to the roller and affecting the clamping of the arc bracket 1 and the arc bracket 2. At the same time, the surface of the roller is only cleaned when the roller rotates slowly, which can avoid accidents such as damage to the roller and the cleaning scraper when the roller rotates faster, or reducing their service life.

[0014] Preferably, the cleaning restriction assembly further comprises a telescopic rod fixedly connected to the outer wall of the arc tube, the outer wall of the telescopic rod is fixedly connected to the inner wall of the arc bracket 1, the outer wall of the telescopic rod is fixedly connected to a friction ring, the outer wall of the rotating shaft 2 is fixedly connected to a fixed ring block, the outer wall of the fixed ring block is rotatably connected to the inner wall of the arc bracket 1, and utilizing the above-mentioned characteristics that when the counterweight block moves outward, it pushes the arc spring plate 2 to move outward, and two piston plates are provided. When the arc spring plate 2 moves, it pushes the piston plate to move outward, and when the piston plate moves outward, the hydraulic oil at its bottom enters the fixed block through the connecting pipe, and the hydraulic After the oil enters the fixed block, it will enter the telescopic rod through the arc tube, causing the telescopic rod to extend outward. When the telescopic rods at both ends extend outward, the friction rings at both ends will be driven to move synchronously, causing the friction rings to contact and squeeze the fixed ring block, making the fixed ring block unable to rotate under the squeezing, thereby controlling the rotating shaft 2 and the arc-shaped bracket 2 to prevent them from rotating. When the arc-shaped spring plate 2 rebounds, it drives the piston plate to reset, and at the same time the hydraulic oil refluxes, and the telescopic rod and friction ring are reset synchronously. Through the operation of the above components, the rotation of the arc bracket 2 can be limited when polishing the steel pipe, thereby avoiding the displacement of the steel pipe during rapid rotation, which in turn causes danger.

[0015] A method for using a steel polishing device for construction engineering includes the following steps:

[0016] S1: Install the device: Before using the device, install it in the required position, place the steel pipe on the arc bracket, and make one end of the steel pipe contact the fixed plate, and then turn on the power of the electric telescopic rod and motor;

[0017] S2: Encircling clamping: After placing the steel pipe on the arc-shaped bracket 1, the arc-shaped bracket 1 will be forced to move downward, and drive the spring plate to move, so that the spring plate squeezes the hydraulic oil at its bottom, so that it enters the hydraulic rod 1 through the hydraulic pipe 1, and the hydraulic rod 1 is extended, pushing the arc-shaped bracket 2 through the rotating shaft 1, and rotating around the rotating shaft 2 as the axis, forming an embracing state for the steel pipe.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that after the steel pipe is placed on the arc-shaped bracket 1, the arc-shaped bracket 1 will be pressed down, and two spring plates are provided. After the steel pipe is placed on the arc-shaped bracket 1, the arc-shaped bracket 1 will move downward due to the weight of the steel pipe. When the arc-shaped bracket 1 moves downward, it will synchronously drive the spring plates to move. When the spring plates move, they will squeeze the hydraulic oil at the bottom thereof, so that the hydraulic oil enters the hydraulic rod 1 through the hydraulic pipe 1, and the hydraulic rod 1 extends upward. When the hydraulic rod 1 extends upward, the arc-shaped bracket 2 is pushed by the rotating shaft 1, so that the arc-shaped bracket 2 rotates with the rotating shaft 2 as the axis, so that the arc-shaped bracket 1 and the arc-shaped bracket 2 can form an embracing state with respect to the steel pipe. At the same time, the hydraulic oil under the spring plates will also The hydraulic oil enters the hydraulic rod 2 through the hydraulic pipe 2, thereby pushing the sliding block and the guide wheel to move, so that the guide wheel contacts and squeezes the steel pipe. When the steel pipe is lifted up and taken out, the spring plate rebounds to make the hydraulic oil return, and the hydraulic rod 1 and the hydraulic rod 2 retract, so that the arc bracket 2 and the guide wheel are reset. Through the operation of the above components, the steel pipe can be automatically clamped when it is placed, avoiding the tedious operation of adjusting the clamping before polishing. At the same time, through the embracing clamping of the arc bracket 1 and the arc bracket 2, the grinding wheel can perform continuous polishing from beginning to end when polishing the steel pipe, avoiding the need to change one end to continue polishing during polishing, which affects the continuity of polishing and work efficiency.

[0020] (2) The present invention utilizes the above-mentioned characteristic that the arc-shaped bracket 1 will be pressed down, and sets two connecting rods 1. When the arc-shaped bracket 1 is lowered by the gravity of the steel pipe, the connecting rod 1 is synchronously driven by the rotating shaft 3 to rotate downward with the rotating rod as the axis. When the connecting rod 1 rotates downward, it drives the rotating rod and the half gear to rotate together. When the half gear rotates, it synchronously drives the half gear at the other end to rotate. When the half gear at the other end rotates, it drives the connecting rod 1 at the other end to rotate downward with the rotating rod at the other end as the axis, and then drives the arc-shaped bracket 1 at the other end to move downward through the rotating shaft 3 at the other end. Through the operation of the above components, when the weight of the two ends of the steel pipe is unequal and the weight of one side is heavier, the arc-shaped brackets 1 on both sides can be lowered to the same position through the half gear and the connecting rod 1, so that the steel pipe remains in a relatively horizontal state, so as to facilitate its subsequent polishing and avoid the steel pipe from tilting during polishing, so that the contact pressure between the grinding wheel and the steel pipe at different positions is different, thereby affecting the polishing of the steel pipe.

[0021] (3) The present invention utilizes the characteristic that the steel pipe rotates rapidly when it is polished. When the steel pipe rotates rapidly, it drives the roller and the rotating block to rotate together. When the rotating block rotates, it is acted upon by centrifugal force and causes the counterweight block to move outward. When the counterweight block moves outward, it pushes the arc spring plate 1 and the arc spring plate 2 to move outward synchronously. When the arc spring plate 1 moves outward, it drives the cleaning scraper to move outward together through the connecting rod 2, so that the cleaning scraper and the roller change from contact to non-contact. After the polishing of the steel pipe is completed, the rotation speed of the steel pipe will gradually decrease. Low, synchronously reduce the speed of the roller and the rotating block, at this time the centrifugal force is reduced, under the action of the arc spring plate 1, the counterweight block begins to retract, and at the same time the cleaning scraper will continue to contact the roller, so that the cleaning scraper can scrape and clean the surface of the roller, avoiding the debris generated when polishing the steel pipe adhering to the roller and affecting the clamping of the arc bracket 1 and the arc bracket 2. At the same time, the surface of the roller is cleaned only when the roller rotates slowly, which can avoid the accidental damage of the roller and the cleaning scraper or reduce their service life when the roller rotates faster.

[0022] (4) The present invention utilizes the above-mentioned characteristic that when the counterweight block moves outward, it pushes the arc spring plate 2 to move outward, and sets two piston plates. When the arc spring plate 2 moves, it pushes the piston plate to move outward. When the piston plate moves outward, the hydraulic oil at its bottom enters the fixed block through the connecting pipe. After the hydraulic oil enters the fixed block, it enters the telescopic rod through the arc tube, causing the telescopic rod to extend outward. When the telescopic rods at both ends extend outward, they will synchronously drive the friction rings at both ends to move, causing the friction rings to contact and squeeze the fixed ring blocks, making the fixed ring blocks unable to rotate under the squeezing, thereby controlling the rotating shaft 2 and the arc bracket 2 so that they cannot rotate. When the arc spring plate 2 rebounds, it drives the piston plate to reset, and at the same time, the hydraulic oil refluxes, and the telescopic rod and the friction ring are synchronously reset. Through the operation of the above components, the rotation of the arc bracket 2 can be limited when polishing the steel pipe, avoiding the displacement of the steel pipe during rapid rotation, thereby causing danger.

When the arc-shaped bracket 301 moves downward, the spring plate 303 is synchronously driven to move. When the spring plate 303 moves, the hydraulic oil at its bottom will be squeezed, so that the hydraulic oil enters the hydraulic pipe 304.

[0040] The automatic clamping mechanism 3 also includes a hydraulic rod 1 305 fixedly connected to the inner wall of the support plate 1, and a rotating shaft 1 306 is fixedly connected to the top of the hydraulic rod 1 305, and an arc-shaped bracket 2 307 is rotatably connected to the outer wall of the rotating shaft 1 306, and a rotating shaft 2 308 is fixedly connected to the outer wall of the arc-shaped bracket 2 307.

After the steel pipe 201 is placed on the arc-shaped bracket 1 301, the arc-shaped bracket 1 301 will be pressed down, and two spring plates 303 are set. After the pipe 201 is placed on the arc-shaped support 1 301, the arc-shaped support 1 301 will move downward due to the weight of the steel pipe 201. When the arc-shaped support 1 301 moves downward, it will synchronously drive the spring plate 303 to move. When the spring plate 303 moves, it will squeeze the hydraulic oil at its bottom, so that the hydraulic oil enters the hydraulic rod 1 305 through the hydraulic pipe 1 304, and the hydraulic rod 1 305 extends upward. When the hydraulic rod 1 305 extends upward, it pushes the arc-shaped support 2 307 through the rotating shaft 1 306, so that the arc-shaped support 2 307 The second rotating shaft 308 rotates as the axis, so that the arc-shaped bracket 1 301 and the arc-shaped bracket 2 307 can form an embracing state around the steel pipe 201. At the same time, the hydraulic oil under the spring plate 303 will enter the hydraulic rod 2 310 through the hydraulic pipe 2 309, thereby pushing the sliding block 311 and the guide wheel 312 to move, so that the guide wheel 312 contacts and squeezes the steel pipe 201. When the steel pipe 201 is lifted up and taken out, the spring plate 303 rebounds to make the hydraulic oil reflux, and the hydraulic rod 1 305 and the hydraulic rod 2 310 retract, so that the arc-shaped bracket 1 301 and the arc-shaped bracket 2 307 can form an embracing state around the steel pipe 201. At the same time, the hydraulic oil under the spring plate 303 will enter the hydraulic rod 2 310 through the hydraulic pipe 2 309, thereby pushing the sliding block 311 and the guide wheel 312 to move, so that the guide wheel 312 contacts and squeezes the steel pipe 201.

Through the operation of the above components, the steel pipe 201 can be automatically clamped when the steel pipe 201 is placed, avoiding the tedious operation of adjusting the clamping before polishing. At the same time, through the embracing clamping of the arc-shaped bracket 1 301 and the arc-shaped bracket 2 307, the grinding wheel 205 can polish the steel pipe 201 continuously from beginning to end, avoiding the need to change one end to continue polishing during polishing, which affects the continuity of polishing and work efficiency.

When the half gear 402 rotates, the half gear 402 at the other end is synchronously driven to rotate. When the half gear 402 at the other end rotates, it drives the connecting rod 1 403 at the other end to rotate downward with the rotating rod 401 at the other end as the axis, and then drives the arc-shaped bracket 1 301 at the other end to move downward through the rotating shaft 3 404 at the other end. Through the operation of the above components, when the weight at both ends of the steel pipe 201 is unequal and the weight on one side is heavier, the arc-shaped bracket 1 301 on both sides can be lowered to the same position through the half gear 402 and the connecting rod 1 403, so that the steel pipe 201 remains in a relatively horizontal state, so as to facilitate its subsequent polishing and avoid the steel pipe 201 from tilting during polishing, so that the contact pressure between the grinding wheel 205 and the steel pipe 201 at different positions is different, thereby affecting the polishing of the steel pipe 201.

[0043] The cleaning limiting assembly 5 includes a rotating block 501 fixedly connected to the outer wall of the roller 302, a counterweight 502 is slidably connected to the inner wall of the rotating block 501, an arc spring plate 503 is slidably connected to the inner wall of the arc bracket 301, a connecting rod 2 504 is fixedly connected to the outer wall of the arc spring plate 1 503, and the outer wall of the connecting rod 2 504 is slidably connected to the inner wall of the arc bracket 1 301. When the steel pipe 201 rotates rapidly, it will drive the roller 302 and the rotating block 501 to rotate together. When the rotating block 501 rotates, the centrifugal force will cause the counterweight 502 to move outward. When the counterweight 502 moves outward, it will push the arc spring plate 1 503 to move outward synchronously.

[0044] The cleaning limiting assembly 5 also includes a cleaning scraper 505 fixedly connected to the outer wall of the connecting rod 2 504, an arc-shaped slide buckle 506 is slidably connected to the inner wall of the arc spring plate 1 503, an arc spring plate 2 507 is slidably connected to the inner wall of the arc bracket 1 301, and a piston plate 508 is fixedly connected to the outer wall of the arc spring plate 2 507. The outer wall of the piston plate 508 is slidably connected to the inner wall of the arc bracket 1 301. When the counterweight block 502 moves outward, it will push the arc spring plate 1 503 and the arc spring plate 2 507 to move outward synchronously. When the arc spring plate 1 503 moves outward, the cleaning scraper 505 is driven to move outward together through the connecting rod 2 504, so that the cleaning scraper 505 and the roller 302 are changed from contact to non-contact. When the arc spring plate 2 507 moves, it will push the piston plate 508 to move outward.

[0045] The cleaning limiting assembly 5 also includes a connecting pipe 509 fixedly connected to the inner wall of the arc-shaped bracket 301, a fixed block 510 fixedly connected to the inner wall of the arc-shaped bracket 301, the inner wall of the fixed block 510 is fixedly connected to the outer wall of the connecting pipe 509, and the inner wall of the fixed block 510 is fixedly connected to the arc tube 511. When the steel pipe 201 is polished, the steel pipe 201 rotates rapidly. When the steel pipe 201 rotates rapidly, the roller 302 and the rotating block 501 are driven to rotate together. When the rotating block 501 rotates, the centrifugal force causes the counterweight 502 to move outward. When the counterweight 502 moves outward, it pushes the arc spring plate 1 503 and the arc spring plate 2 507 to move outward synchronously. When the arc spring plate 1 503 moves outward, the cleaning scraper 505 is driven to move outward together through the connecting rod 2 504. The cleaning scraper 505 is moved so that the contact between the cleaning scraper 505 and the roller 302 changes to non-contact. After the polishing of the steel pipe 201 is completed, the rotation speed of the steel pipe 201 will gradually decrease, and the rotation speed of the roller 302 and the rotating block 501 will be reduced synchronously. At this time, the centrifugal force is reduced, and the counterweight block 502 begins to retract under the action of the arc spring plate 1 503. At the same time, the cleaning scraper 505 will continue to contact the roller 302, so that the cleaning scraper 505 can scrape and clean the surface of the roller 302, avoiding the debris generated during the polishing of the steel pipe 201 from adhering to the roller 302 and affecting the clamping of the arc bracket 1 301 and the arc bracket 2 307. At the same time, the surface of the roller 302 is cleaned only when the roller 302 rotates slowly, which can avoid the accident of damage to the roller 302 and the cleaning scraper 505 or shortening their service life when the roller 302 rotates quickly.

[0046] The cleaning restriction assembly 5 also includes a telescopic rod 512 fixedly connected to the outer wall of the arc tube 511, the outer wall of the telescopic rod 512 is fixedly connected to the inner wall of the arc bracket 301, the outer wall of the telescopic rod 512 is fixedly connected to a friction ring 513, the outer wall of the rotating shaft 308 is fixedly connected to a fixed ring block 514, the outer wall of the fixed ring block 514 is rotatably connected to the inner wall of the arc bracket 301, and utilizing the above-mentioned characteristics, when the counterweight block 502 moves outward, it pushes the arc spring plate 2 507 to move outward, and two piston plates 508 are set. When the arc spring plate 2 507 moves, it pushes the piston plate 508 to move outward. When the piston plate 508 moves outward, the hydraulic oil at the bottom of the piston plate enters the fixed block 510 through the connecting pipe 509, and the hydraulic oil After entering the fixed block 510, it will enter the telescopic rod 512 through the arc tube 511, causing the telescopic rod 512 to extend outward. When the telescopic rods 512 at both ends extend outward, the friction rings 513 at both ends will be driven to move synchronously, causing the friction rings 513 to contact and squeeze the fixed ring block 514, so that the fixed ring block 514 cannot rotate under the squeezing, thereby controlling the rotating shaft 2 308 and the arc bracket 2 307 to prevent them from rotating. When the arc spring plate 2 507 rebounds, it drives the piston plate 508 to reset, and at the same time the hydraulic oil refluxes, and the telescopic rod 512 and the friction ring 513 are reset synchronously. Through the operation of the above components, the rotation of the arc bracket 2 307 can be limited when polishing the steel pipe 201, thereby avoiding the displacement of the steel pipe 201 during rapid rotation, which in turn causes danger.

[0047] The method for using the steel polishing device for construction engineering includes the following steps:

[0048] S1: Installing the device: Before using the device, first install it in the desired location, place the steel pipe 201 on the arc-shaped bracket 301, and make one end of the steel pipe 201 contact the fixed plate 103, then turn on the power of the electric telescopic rod 202 and the motor 204;

[0049] S2: Encircling clamping: After the steel pipe 201 is placed on the arc-shaped bracket 1 301, the arc-shaped bracket 1 301 will be forced to move downward, and drive the spring plate 303 to move, so that the spring plate squeezes the hydraulic oil at its bottom, so that it enters the hydraulic rod 1 305 through the hydraulic pipe 1 304, allowing the hydraulic rod 1 305 to extend, and push the arc-shaped bracket 2 307 through the rotating shaft 1 306, and rotate around the rotating shaft 2 308 as the axis, forming an embracing state for the steel pipe 201.

[0050] A specific application of this embodiment is as follows: before using the device, the device is first installed at the required position, the steel pipe 201 is placed on the arc-shaped bracket 1301, and one end of the steel pipe 201 is in contact with the fixed plate 103, and then the power of the electric telescopic rod 202 and the motor 204 is turned on. After the steel pipe 201 is placed on the arc-shaped bracket 1301, the arc-shaped bracket 1301 will move downward due to the gravity of the steel pipe 201. When the arc-shaped bracket 1301 moves downward, the spring plate 303 is synchronously driven to move. When the spring plate 303 moves, the hydraulic oil at the bottom thereof is squeezed, so that the hydraulic oil enters the hydraulic rod 1305 through the hydraulic pipe 1304, allowing the hydraulic rod 1305 to extend upward. When the hydraulic rod 1305 extends upward, the hydraulic oil is squeezed out by the rotation of the spring plate 303. The movable shaft 1 306 pushes the arc bracket 2 307, causing the arc bracket 2 307 to rotate around the rotating shaft 2 308, so that the arc bracket 1 301 and the arc bracket 2 307 can form an embracing state around the steel pipe 201. At the same time, the hydraulic oil under the spring plate 303 will also enter the hydraulic rod 2 310 through the hydraulic pipe 2 309, thereby pushing the sliding block 311 and the guide wheel 312 to move, so that the guide wheel 312 contacts and squeezes the steel pipe 201. When the steel pipe 201 is lifted up and taken out, the spring plate 303 rebounds to cause the hydraulic oil to flow back, and the hydraulic rod 1 305 and the hydraulic rod 2 310 retract, so that the arc bracket 2 307 and the guide wheel 312 are reset. Through the operation of the above components, the steel pipe 201 can be automatically clamped when it is placed. , avoiding the tedious operation of adjusting the clamping before polishing. At the same time, through the embracing clamping of the arc bracket 1 301 and the arc bracket 2 307, the grinding wheel 205 can perform continuous polishing from the beginning to the end when polishing the steel pipe 201, avoiding the need to change one end to continue polishing during polishing, which affects the continuity and work efficiency during polishing. When the arc bracket 1 301 is lowered by the gravity of the steel pipe 201, the connecting rod 1 403 is synchronously driven by the rotating shaft 3 404, and rotates downward with the rotating rod 401 as the axis. When the connecting rod 1 403 rotates downward, it drives the rotating rod 401 and the half gear 402 to rotate together. When the half gear 402 rotates, it synchronously drives the half gear 402 at the other end to rotate, and at the other end When the half gear 402 rotates, it drives the connecting rod 1 403 at the other end to rotate downward with the rotating rod 401 at the other end as the axis, and then drives the arc-shaped bracket 1 301 at the other end to move downward through the rotating shaft 3 404 at the other end. Through the operation of the above components, when the weights at both ends of the steel pipe 201 are unequal and the weight on one side is heavier, the half gear 402 and the connecting rod 1 403 can also make the arc-shaped bracket 1 301 on both sides drop to the same position, so that the steel pipe 201 remains in a relatively horizontal state, so as to facilitate its subsequent polishing and avoid the steel pipe 201 from tilting during polishing, so that the contact pressure between the grinding wheel 205 and the steel pipe 201 at different positions is different, thereby affecting the polishing of the steel pipe 201.

[0051] By utilizing the characteristic that the steel pipe 201 rotates rapidly when polishing the steel pipe 201, when the steel pipe 201 rotates rapidly, it drives the roller 302 and the rotating block 501 to rotate together. When the rotating block 501 rotates, the centrifugal force causes the counterweight 502 to move outward. When the counterweight 502 moves outward, it pushes the arc spring plate 1 503 and the arc spring plate 2 507 to move outward synchronously. When the arc spring plate 1 503 moves outward, the cleaning scraper 505 is driven to move outward together through the connecting rod 2 504, so that the cleaning scraper 505 and the roller 302 are changed from contact to non-contact. After the polishing of the steel pipe 201 is completed, the rotation speed of the steel pipe 201 will gradually decrease, and at the same time The rotation speed of the roller 302 and the rotating block 501 is reduced in this step. At this time, the centrifugal force is reduced, and the counterweight block 502 begins to retract under the action of the arc spring plate 1 503. At the same time, the cleaning scraper 505 will continue to contact the roller 302, so that the cleaning scraper 505 can scrape and clean the surface of the roller 302, thereby preventing the debris generated when polishing the steel pipe 201 from adhering to the roller 302 and affecting the clamping of the arc bracket 1 301 and the arc bracket 2 307. At the same time, the surface of the roller 302 is cleaned only when the roller 302 rotates slowly, thereby avoiding the accidental damage of the roller 302 and the cleaning scraper 505 or reducing their service life when the roller 302 rotates quickly.

[0052] Taking advantage of the above-mentioned feature that when the counterweight block 502 moves outward, it pushes the arc spring plate 2 507 to move outward, and two piston plates 508 are provided. When the arc spring plate 2 507 moves, it pushes the piston plate 508 to move outward. When the piston plate 508 moves outward, the hydraulic oil at the bottom thereof enters the fixed block 510 through the connecting pipe 509. After the hydraulic oil enters the fixed block 510, it enters the telescopic rod 512 through the arc tube 511, causing the telescopic rod 512 to extend outward. When the telescopic rods 512 at both ends extend outward, they will synchronously drive the friction rings at both ends. 513 moves, causing the friction ring 513 to contact and squeeze the fixed ring block 514, so that the fixed ring block 514 cannot rotate under the squeezing, thereby controlling the rotating shaft 2 308 and the arc-shaped bracket 2 307, so that they cannot rotate. When the arc-shaped spring plate 2 507 rebounds, it drives the piston plate 508 to reset, and at the same time the hydraulic oil refluxes, and the telescopic rod 512 and the friction ring 513 reset synchronously. Through the operation of the above components, the rotation of the arc-shaped bracket 2 307 can be limited when polishing the steel pipe 201, avoiding the displacement of the steel pipe 201 during rapid rotation, which in turn causes danger.
