Description

Technical Field

[0001] This invention relates to the field of edge burr grinding technology for guardrails, and more particularly to an edge burr grinding machine for highway guardrails. Background Technology

[0002] Burrs are a common and unavoidable phenomenon in machining processes. They affect many aspects of the manufacturing process, including machining accuracy, part calibration during clamping, machine usage requirements, positioning during reprocessing, worker safety, and the final appearance quality of the parts. High-speed guardrails also develop burrs on the cut surface after machining, affecting product functionality and worker safety; therefore, these burrs need to be removed. The most common deburring grinding mechanism is surface grinding, which drives a high-speed rotating grinding wheel to remove burrs from the workpiece's end face. This method is labor-intensive, inefficient, and lacks precision.

[0003] The edge deburring machine for highway guardrails, with announcement number CN107498114B, has a grinding mechanism mounted on a worktable. An adjustment mechanism is connected to the grinding mechanism to adjust its reciprocating movement along the length of the worktable. A drive mechanism is mounted on the grinding mechanism to drive it to grind. The grinding mechanism includes a base plate, an inclined platform, and a crank-connecting rod assembly. The inclined platform is fixed to the base plate, and the crank-connecting rod assembly is fixed to the inclined surface of the inclined platform. A file is located at the end of the crank-connecting rod assembly away from the inclined platform. The drive mechanism is connected to the crank-connecting rod assembly so that the file's movement trajectory is "D"-shaped. This movement trajectory includes an arc segment and a straight segment, with the arc segment above the straight segment and the straight segment parallel to the slope of the inclined platform. This edge deburring machine can efficiently and precisely grind the burrs generated on the cut surface of highway guardrails after cutting, reducing labor burden.

[0004] The above technical solution cannot quickly adjust the position and angle of the guardrail, which makes it impossible to effectively respond to changes in the shape of the guardrail surface and to carry out efficient finishing treatment after the guardrail is formed. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an edge burr grinding machine for highway guardrails.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A burr-removing machine for highway guardrails includes a mounting base, a fixed frame fixed to one side of the mounting base, a support frame fixed to the upper side of the fixed frame, the support frame being located at the upper end of the mounting base, an adjustment mechanism on the support frame, a linkage rod on the adjustment mechanism, a moving mechanism at the lower end of the linkage rod, a fixed plate and a rotating plate on the moving mechanism, and the lower ends of the fixed plate and the rotating plate on opposite sides being hinged to each other. A control mechanism is provided on one side of the rotating plate, and an abutting plate is provided on the control mechanism. A vertical plate is fixed on one side of the rotating plate, and a driving mechanism is provided on the vertical plate. The driving mechanism is provided with a positioning rod and a support shaft. A grinding part is detachably connected to one end of the support shaft. A linkage assembly is rotatably sleeved on the support shaft. The positioning rod is disposed through the rotating plate on the side away from the fixed plate. The lower end of the positioning rod is fixed to the upper end of the linkage assembly. Three linkage shaft rods are provided on the upper end of the vertical plate and the rotating plate. Two linkage shaft rods are rotatably sleeved on the side of the vertical plate close to the rotating plate from top to bottom. The other linkage shaft rod is rotatably sleeved on the upper end of the rotating plate. A rope assembly is sleeved on all three linkage shaft rods. A synchronization rod is fixed between the rope assembly and the positioning rod. The contact plate and the rope assembly are fixedly connected.

[0007] Compared with the prior art, the present invention can adjust the height and angle of the fixed plate as needed, and can adjust the position and angle of the rotating plate to fully realize the adjustment of the position of the grinding part, so that the grinding part can fully adapt to the shape and structure of the guardrail; and can make the grinding part rotate to perform grinding operations on the surface and edges of the metal guardrail, thereby removing burrs from the edges of the guardrail.

[0008] Preferably, the adjusting mechanism includes a first motor assembly fixed to one side of the support frame, a sleeve rotatably sleeved on the support frame, transmission wheels fixed to the ends of the output shafts of the sleeve and the first motor assembly, a transmission belt sleeved between the two transmission wheels, a shaft assembly penetrating through the sleeve, a linkage rod penetrating through the shaft assembly, the linkage rod slidably sleeved on the shaft assembly, a lifting mechanism provided on the linkage rod, and the lifting mechanism connected to the upper end of the fixed frame.

[0009] Furthermore, the motor mounting bracket component allows the first motor assembly to be fixed to one side of the support frame. The output shaft end of the first motor assembly can be fixed with a transmission wheel via a coupling or other components, which can drive the transmission wheel to rotate. At the same time, another transmission wheel passes through and is fixed to the sleeve. A hole is opened at the end of the support frame away from the fixed frame, and a bearing is installed in the hole. The sleeve is fixed in the bearing and can rotate. The two transmission wheels can rotate synchronously via a transmission belt to drive the sleeve to rotate. During manufacturing, the transmission belt and transmission wheels can be set with a toothed structure to ensure the power transmission effect.

[0010] Preferably, the lifting mechanism includes a first electric telescopic rod rotatably connected to the upper end of the fixed frame, an arc-shaped sliding member rotatably connected to the piston rod end of the first electric telescopic rod, a shaft collar member passing through the shaft assembly, one end of the linkage rod passing through the shaft assembly and fixed to one end side wall inside the shaft collar member, the arc-shaped sliding member slidingly sleeved on the shaft collar member, and the linkage rod, shaft assembly, shaft collar member and arc-shaped sliding member being coaxially arranged.

[0011] Furthermore, the first electric telescopic rod is an existing electric telescopic component, generally comprising a circular tube, a rod body that passes through the circular tube and can move relative to the circular tube, and a motor drive component installed on one side and inside the circular tube. The motor drive component is connected to one end of the rod body located inside the circular tube, enabling the rod body to move relative to the circular tube. The extension and retraction of the first electric telescopic rod can drive the arc-shaped sliding member to change position. At the same time, due to the action of the collar member, shaft assembly, and linkage rod, the arc-shaped sliding member can only move up and down relative to the support frame. This results in the arc-shaped sliding member being able to drive the collar member to move up and down along the shaft assembly without affecting the relative rotation between the collar member and the arc-shaped sliding member. It also allows the collar member to rotate coaxially with the shaft assembly and linkage rod.

[0012] Preferably, the moving mechanism includes a third electric telescopic rod fixed to one side of the lower end of the linkage rod. The third electric telescopic rod is located at the lower end of the support frame. The piston rod end of the third electric telescopic rod is fixed to one side of the upper end of the fixed plate. The upper ends of the fixed plate and the rotating plate are jointly provided with a T-shaped groove. A T-shaped component is slidably installed in the T-shaped groove. The lower end of the linkage rod is fixed to the upper end of the T-shaped component.

[0013] Furthermore, the lower end of the linkage rod extends to the lower end of the support frame, and through the cooperation of the T-shaped piece and the T-slot, it can drive the fixed plate to rotate synchronously. At the same time, through the action of the third electric telescopic rod, the fixed plate can be moved relative to the linkage rod for adjustment as needed.

[0014] Preferably, the control mechanism includes a bearing groove formed on one side of the rotating plate, with straight rods fixed to opposite sidewalls within the bearing groove. A bearing block is slidably mounted on the straight rod, and the bearing block is located within the bearing groove. A second spring is sleeved on the straight rod, with its two ends fixed to one side of the bearing block and one end sidewall within the bearing groove, respectively. A support plate is fixed to one side of the bearing block, and a second electric telescopic rod is rotatably connected to the lower end of the support plate and one side of the fixed plate. An abutment mechanism is provided on one side of the bearing block, and the abutment mechanism is connected to the abutment plate.

[0015] Furthermore, the second electric telescopic rod can extend and retract as needed. When the second electric telescopic rod retracts, it drives the support plate to move the bearing block along the straight rod, causing the bearing block to abut against the side wall of the bearing groove near the fixed plate. This causes the rotating plate to rotate counterclockwise, making the rotating plate abut against the side wall of the fixed plate, forming a rectangle. The lower sides of the abutting ends of the fixed plate and rotating plate are connected by hinges or hinges, facilitating relative rotation between the fixed plate and rotating plate. When the second electric telescopic rod extends, it causes the bearing block to move towards the side wall of the bearing groove away from the fixed plate. During manufacturing, a suitable spring component is selected, and its elastic coefficient is fully controlled so that the bearing block applies pressure to the rotating plate through the second spring component, causing the rotating plate to rotate clockwise relative to the fixed plate. This ensures the stability of the rotating plate's rotation and its position after rotation. Moreover, the abutting operation provides power for adjusting the position of the grinding part.

[0016] Preferably, the abutting mechanism includes a notch formed on one side of the upper end of the rotating plate, the lower end of the notch and the top of the bearing groove are connected through the notch, the abutting plate is slidably installed in the notch, a first spring is fixed on one side wall of the abutting plate and the notch, a partition is provided through the notch, the lower end of the partition extends into the bearing groove, the partition is fixedly connected to the bearing block, and the partition is disposed on one side of the abutting plate.

[0017] Furthermore, by selecting a suitable first spring component, the position of the contact plate component can be fixed by the first spring component to prevent the contact plate component from moving arbitrarily. When the bearing block drives the partition component to move towards the contact plate component, the contact plate component will squeeze the first spring component. At the same time, the contact plate component will drive the rope assembly to move. When the contact plate component moves towards the fixed plate, the rope assembly will drive the positioning rod to descend through the synchronous rod component. The descent of the positioning rod component will cause the linkage assembly to push the support shaft to descend, so that the grinding part will descend. In addition, during use, the moving speed of the partition component should be fully controlled so that the partition component moves at an appropriate speed. This will ensure that the elasticity of the first spring component is released slowly and avoid the contact plate component from reciprocating.

[0018] Preferably, the drive mechanism includes a second motor assembly mounted on one side of the rotating plate, an adaptation mechanism is provided on the side of the vertical plate away from the rotating plate, and synchronous pulleys are mounted on the other end of the support shaft, the end of the piston rod of the second motor assembly, and the adaptation mechanism, and a synchronous belt is sleeved between the three synchronous pulleys.

[0019] Furthermore, the second motor assembly can drive the synchronous pulley fixed to it to rotate, which in turn drives the synchronous belt to make the other two synchronous pulleys rotate. It can drive the grinding parts to rotate through the support shaft, so that the grinding parts can grind and deburr the highway guardrail. In actual use, the grinding parts and support shaft are detachably connected for easy replacement.

[0020] Preferably, the adaptation mechanism includes an elastic telescopic component installed on the side of the vertical plate away from the rotating plate, a sliding member is installed on the elastic telescopic component, the sliding member is slidably installed inside the vertical plate, and a rotating shaft is fixed to one side of one of the synchronous pulleys, the rotating shaft being rotatably sleeved on one side of the sliding member.

[0021] Furthermore, the elastic telescopic component consists of a rod and a vertical spring sleeved on the rod. A sliding member is sleeved on the rod, and the lower end of the sliding member is fixed to the vertical spring inside the elastic telescopic component. The sliding member is located inside the vertical plate and at the upper end of the vertical plate. When the support shaft drives the synchronous pulley fixed to it to descend, the synchronous belt will apply pressure to the synchronous pulley on one side of the vertical plate. This causes the synchronous pulley to drive the sliding member to squeeze the vertical spring and descend. The action of the vertical spring ensures a reverse force, allowing the synchronous belt to be fully tensioned.

[0022] Preferably, the upper end of the mounting base is provided with a clamping assembly, which is located at the lower end of the support frame.

[0023] Furthermore, the clamping components can effectively secure the highway guardrails for grinding and deburring operations.

[0024] Preferably, a through opening is provided on one side of the shaft assembly, and a lifting block is slidably installed in the through opening. The two ends of the lifting block are respectively fixed to one side of the linkage rod and the side wall inside the shaft collar.

[0025] Furthermore, the cross-section of the shaft assembly is C-shaped, and the lifting block passes through the C-shaped opening. That is, when the shaft assembly rotates, the side wall of the opening abuts against the lifting block, causing the lifting block to drive the linkage rod and the shaft collar to rotate coaxially, and the rotation of the shaft collar will not affect the operation of the arc-shaped sliding component.

[0026] The beneficial effects of this invention are: 1. The clamping assembly can clamp the highway guardrail to ensure its stability on the upper part of the mounting base, so as to control the grinding parts to perform grinding and deburring operations on the surface and edges of the highway guardrail. 2. By extending and retracting the first electric telescopic rod, the arc-shaped sliding component can drive the collar component to rise and fall relative to the shaft assembly. The collar component can drive the linkage rod to rise and fall through the lifting block. The rise and fall of the linkage rod can achieve the purpose of initially adjusting the height of the grinding component, which is convenient for quickly adapting to the structure of the highway guardrail. 3. The first motor assembly, two transmission wheels and transmission belt enable the sleeve to drive the shaft assembly to rotate. The shaft assembly drives the linkage rod to rotate through the lifting block. The linkage rod drives the fixed plate to rotate through the T-shaped part, quickly adjusting the relative position of the grinding part and the mounting base. 4. When the second electric telescopic rod retracts, it causes the support plate to drive the straight rod to contact the side wall of the bearing groove near the fixed plate. The partition plate squeezes the contact plate to move towards the fixed plate, which drives the rope assembly to operate. It also causes the synchronous rod to drive the positioning rod to descend. The positioning rod drives the support shaft and grinding parts to descend through the linkage assembly, which can perform grinding and deburring operations on the vertical surface of the highway guardrail. 5. By extending the second electric telescopic rod, the bearing block can push the rotating plate relative to the fixed plate through the second spring, which can adjust the angle and position of the grinding part to adapt to the inclined surface of the highway guardrail, so as to carry out grinding and deburring operations. 6. Through the action of the elastic telescopic component and the sliding component, the synchronous belt can apply pressure to the synchronous pulley on the sliding component, so that when the position of the synchronous pulley on the support shaft changes, it also changes accordingly, and can also ensure that the synchronous belt is always in a taut state, ensuring stable power transmission.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1-8 A deburring machine for highway guardrails includes a mounting base 1. Control components and cable components can be installed in the mounting base 1 to connect with automated components within the device and control their operation. A fixing frame 3 is fixed to one side of the mounting base 1, and the fixing frame 3 and the mounting base 1 are secured by bolts to ensure the stability of their relative positions. A support frame 6 is fixed to the upper side of the fixing frame 3, and the support frame 6 and the fixing frame 3 are also connected and secured by bolts. The support frame 6 is located at the upper end of the mounting base 1. A clamping assembly 2 is provided at the upper end of the mounting base 1, and the clamping assembly 2 is located at the lower end of the support frame 6. The clamping assembly 2 effectively clamps the highway guardrail, ensuring its positional stability and facilitating the deburring operation of the grinding component 19. In actual operation, a rotating tube is provided at one end of the clamping assembly 2 extending from the mounting base 1, allowing it to rotate and clamp both sides of the highway guardrail, enabling movement.

[0030] In this embodiment, the support frame 6 is provided with an adjustment mechanism, and the adjustment mechanism is provided with a linkage rod 12. The adjustment mechanism includes a first motor assembly 7 fixed to one side of the support frame 6. A sleeve 23 is rotatably sleeved on the support frame 6. Both the sleeve 23 and the output shaft of the first motor assembly 7 are fixed with transmission wheels 24. A transmission belt 22 is sleeved between the two transmission wheels 24. A shaft assembly 5 is passed through the sleeve 23. The linkage rod 12 is passed through the shaft assembly 5 and is slidably sleeved on the shaft assembly 5. The first motor assembly 7 is installed on one side of the support frame 6 through a motor frame. The output shaft of the first motor assembly 7 is connected to the transmission wheel 24 through a coupling so that the transmission wheel 24 rotates with the output shaft of the first motor assembly 7. The transmission wheel 24 can cause the transmission belt 22 to drive the other transmission wheel 24 to rotate. The other transmission wheel 24 can drive the sleeve 23 to rotate. The transmission wheel 24 and the sleeve 23 are fixedly connected and can rotate synchronously. The sleeve 23 and the shaft assembly 5 are fixedly connected. When the sleeve 23 rotates, it can cause the shaft assembly 5 to rotate.

[0031] In this embodiment, a lifting mechanism is provided on the linkage rod 12, and the lifting mechanism is connected to the upper end of the fixed frame 3. The lifting mechanism includes a first electric telescopic rod 4 rotatably connected to the upper end of the fixed frame 3. An arc-shaped sliding member 20 is rotatably connected to the piston rod end of the first electric telescopic rod 4. A shaft sleeve 5 is provided with a shaft collar 21. One end of the linkage rod 12 passes through the shaft sleeve 5 and is fixed to one end side wall inside the shaft collar 21. The arc-shaped sliding member 20 is slidably sleeved on the shaft collar 21. The linkage rod 12, shaft sleeve 5, shaft collar 21, and arc-shaped sliding member 20 are coaxially arranged. A through-hole 43 is opened on one side of the shaft sleeve 5. A lifting block 44 is slidably installed in the through-hole 43. The two ends of the lifting block 44 are respectively fixed to one side of the linkage rod 12 and the side wall inside the shaft collar 21. The arc-shaped sliding member 20 adopts an arc-shaped mechanism, which can fit... The first motor assembly 7 is mounted on the collar 21 and can rotate relative to the arc-shaped sliding member 20. When the shaft assembly 5 rotates, it can push the lifting block 44 to make the linkage rod 12 fixed to the lifting block 44 and the collar 21 rotate. The rotation angle of the first motor assembly 7 can be precisely controlled, which facilitates the control of the rotation angle of the shaft assembly 5. At the same time, through the cooperation of the lifting block 44 and the linkage rod 12, the T-shaped member 14 can be driven to rotate, which can precisely adjust the rotation angle of the fixed plate 8 relative to the support frame 6, that is, it can precisely adjust the rotation angle of the fixed plate 8 relative to the lower highway guardrail. Moreover, through the extension and retraction of the first electric telescopic rod 4, the arc-shaped sliding member 20 can be raised and lowered by the lifting block 44 and the linkage rod 12, so that the position height of the fixed plate 8 can be adjusted by the T-shaped member 14, and the distance between the fixed plate 8 and the lower highway guardrail can be adjusted.

[0032] In this embodiment, the lower end of the linkage rod 12 is provided with a moving mechanism, and the moving mechanism is provided with a fixed plate 8 and a rotating plate 9. The lower ends of the fixed plate 8 and the rotating plate 9 on opposite sides are hinged to each other. The lower ends of the fixed plate 8 and the rotating plate 9 on opposite sides are connected to a hinge or hinge component. When the hinge is installed, it can rotate relative to the hinge axis. When in use, the fixed plate 8 is basically in a horizontal state, that is, the rotating plate 9 can rotate.

[0033] In this embodiment, the moving mechanism includes a third electric telescopic rod 11 fixed to one side of the lower end of the linkage rod 12. The third electric telescopic rod 11 is located at the lower end of the support frame 6. The piston rod end of the third electric telescopic rod 11 is fixed to one side of the upper end of the fixed plate 8. The upper ends of the fixed plate 8 and the rotating plate 9 are jointly provided with a T-shaped groove 15. A T-shaped piece 14 is slidably installed in the T-shaped groove 15. The lower end of the linkage rod 12 is fixed to the upper end of the T-shaped piece 14. The third electric telescopic rod 11 can extend and retract. When the third electric telescopic rod 11 extends, it can push one end of the fixed plate 8 to move away from the linkage rod 12. This will cause the rotating plate 9 to move towards the linkage rod 12. The third electric telescopic rod 11 can rotate with the linkage rod 12, which can ensure the stability of the relative movement between the fixed plate 8, the rotating plate 9 and the linkage rod 12.

[0034] In this embodiment, a control mechanism is provided on one side of the rotating plate 9. The control mechanism includes an abutment plate 28. The control mechanism includes a bearing groove 34 on one side of the rotating plate 9. Straight rods 33 are fixed to opposite sidewalls within the bearing groove 34. A bearing block 32 is slidably mounted on the straight rod 33, located within the bearing groove 34. A second spring 31 is sleeved on the straight rod 33. The two ends of the second spring 31 are respectively fixed to one side of the bearing block 32 and one end sidewall within the bearing groove 34. A support plate 35 is fixed to one side of the bearing block 32. The lower end of the support plate 35 and one side of the fixed plate 8 are rotatably connected to a second electric telescopic rod 10. An abutment mechanism is provided on one side of the bearing block 32, connected to the abutment plate 28. The second electric telescopic rod 10 can extend and retract as needed. When the second electric telescopic rod 10 retracts, it drives the support plate 35, causing the bearing block 32 to extend along… When the straight rod 33 moves, the bearing block 32 and the side wall of the bearing groove 34 near the fixed plate 8 will come into contact. This will drive the rotating plate 9 to rotate counterclockwise, causing the rotating plate 9 and the side wall of the fixed plate 8 to come into contact, forming a rectangle. The lower side of the contacting end of the fixed plate 8 and the rotating plate 9 is connected by a hinge or hinge to facilitate relative rotation between the fixed plate 8 and the rotating plate 9. When the second electric telescopic rod 10 extends, the bearing block 32 will move towards the side wall of the bearing groove 34 away from the fixed plate 8. During manufacturing, a suitable spring component is selected, and its elastic coefficient is fully controlled so that the bearing block 32 can apply pressure to the rotating plate 9 through the second spring component 31, causing the rotating plate 9 to rotate clockwise relative to the fixed plate 8, ensuring the stability of the rotation of the rotating plate 9 and the stability of its position after rotation. Moreover, the contact operation can provide power for adjusting the position of the grinding part 19.

[0035] In this embodiment, the abutment mechanism includes a notch 30 on one side of the upper end of the rotating plate 9. The lower end of the notch 30 and the top of the bearing groove 34 are connected through it. The abutment plate 28 is slidably installed in the notch 30. A first spring 27 is fixed on one side wall of both the abutment plate 28 and the notch 30. A partition 29 is provided through the notch 30. The lower end of the partition 29 extends into the bearing groove 34. The partition 29 and the bearing block 32 are fixedly connected. The partition 29 is located on one side of the abutment plate 28. By selecting a suitable first spring 27, the position of the abutment plate 28 can be fixed by the first spring 27 to prevent the abutment plate 28 from moving arbitrarily. When the bearing block 32... When the partition 29 moves toward the contact plate 28, the contact plate 28 will compress the first spring 27. At the same time, the contact plate 28 will move the rope assembly 25. When the contact plate 28 moves toward the fixed plate 8, the rope assembly 25 will drive the positioning rod 38 to descend through the synchronous rod 36. The descent of the positioning rod 38 will cause the linkage assembly 41 to push the support shaft 40 to descend, so that the grinding part 19 will descend. In use, the moving speed of the partition 29 should be fully controlled so that the partition 29 moves at an appropriate speed. This will ensure that the elasticity of the first spring 27 is released slowly and avoid the contact plate 28 from reciprocating.

[0036] In this embodiment, a vertical plate 17 is fixed to one side of the rotating plate 9. A driving mechanism is provided on the vertical plate 17. The driving mechanism is provided with a positioning rod 38 and a support shaft 40. The driving mechanism includes a second motor assembly 42 installed on one side of the rotating plate 9. An adaptation mechanism is provided on the side of the vertical plate 17 away from the rotating plate 9. Synchronous pulleys 39 are installed on the other end of the support shaft 40, the piston rod end of the second motor assembly 42, and the adaptation mechanism. A synchronous belt 18 is sleeved together among the three synchronous pulleys 39. The second motor assembly 42 can drive the synchronous pulleys 39 fixed to it to rotate. The synchronous pulleys 39 can drive the synchronous belt 18 to make the other two synchronous pulleys 39 rotate. The grinding part 19 can be driven to rotate through the support shaft 40, which facilitates the grinding part 19 to grind and deburr the highway guardrail. In actual use, the grinding part 19 and the support shaft 40 can be detachably connected for easy replacement.

[0037] In this embodiment, the adapting mechanism includes an elastic telescopic assembly 37 installed on the side of the vertical plate 17 away from the rotating plate 9. A sliding member 13 is installed on the elastic telescopic assembly 37 and is slidably installed inside the vertical plate 17. A rotating shaft 16 is fixed to one side of one of the synchronous pulleys 39 and is rotatably sleeved on one side of the sliding member 13. The elastic telescopic assembly 37 consists of a rod and a vertical spring sleeved on the rod. The sliding member 13 is sleeved on the rod, and the lower end of the sliding member 13 is inside the elastic telescopic assembly 37. The vertical spring is fixed, and the sliding member 13 is located inside the vertical plate 17. The sliding member 13 is located at the upper end inside the vertical plate 17. When the support shaft 40 drives the synchronous wheel 39 fixed to it to descend, the synchronous belt 18 will apply pressure to the synchronous wheel 39 on one side of the vertical plate 17. This will cause the synchronous wheel 39 to drive the sliding member 13 to squeeze the vertical spring to descend. The action of the vertical spring can ensure the reverse force, so that the synchronous belt 18 can be fully tensioned to ensure stable power rotation, so that the grinding part 19 can rotate stably.

[0038] In this embodiment, a grinding component 19 is detachably connected to one end of the support shaft 40, which can be replaced as needed. A linkage assembly 41 is rotatably sleeved on the support shaft 40. A positioning rod 38 is disposed through the side of the rotating plate 9 away from the fixed plate 8. The lower end of the positioning rod 38 is fixed to the upper end of the linkage assembly 41. Three linkage shaft rods 26 are provided on the upper ends of the vertical plate 17 and the rotating plate 9. Two linkage shaft rods 26 are rotatably sleeved from top to bottom on the side of the vertical plate 17 near the rotating plate 9. Two bearings are fixed on the side of the vertical plate 17 near the rotating plate 9. One end of two linkage shaft rods 26 is fixed to the inner ring of these two bearings. The other linkage shaft rod 26 is rotatably sleeved on the upper end of the rotating plate 9. During installation, a bracket can be fixed on the rotating plate 9. Bearing components are installed on the upper part, and one end of the linkage shaft 26 is fixed inside the bearing component. The linkage shaft 26 is arranged parallel to the upper end of the rotating plate 9. The three linkage shafts 26 are arranged parallel to each other. A rope assembly 25 is sleeved on the three linkage shafts 26. A synchronous rod 36 is fixed between the rope assembly 25 and the positioning rod 38. When the rope assembly 25 moves with the abutment plate 28, it can drive the synchronous rod 36 through the rope assembly 25 to make the positioning rod 38 descend. The positioning rod 38 can push the linkage assembly 41 to descend. The linkage assembly 41 can drive the support shaft 40 to descend, and the support shaft 40 can rotate relative to the linkage assembly 41 so that when the synchronous wheel 39 on the support shaft 40 rotates, it can drive the grinding part 19 to rotate to perform grinding and deburring of the highway guardrail.

[0039] In this embodiment, the abutment plate 28 and the rope assembly 25 are fixedly connected. When the abutment plate 28 can move, it will drive the rope assembly 25 to move, so that the rope assembly 25 can drive the positioning rod 38 to rise and fall through the synchronizing rod 36.

[0040] In this invention, after the highway guardrail is formed, it needs to be polished to remove burrs so that the surface of the highway guardrail is smooth. The highway guardrail is then clamped by the clamping assembly 2. The first electric telescopic rod 4 can drive the collar 21 to descend along the shaft assembly 5 through the arc-shaped sliding member 20. The collar 21 drives the linkage rod 12 to descend through the lifting block 44 so that the fixing plate 8 can descend and approach the highway guardrail. The first motor assembly 7 can drive the sleeve 23 to rotate via the transmission belt 22 and two transmission wheels 24. The sleeve 23 can drive the shaft assembly 5, which in turn can drive the linkage rod 12 to rotate via the lifting block 44. The linkage rod 12 can drive the fixed plate 8 to rotate via the T-shaped part 14. The fixed plate 8 can be moved via the third electric telescopic rod 11 to adjust the distance between the grinding part 19 and the highway guardrail. When the second electric telescopic rod 10 retracts, the support plate 35 causes the straight rod 33 and the side wall of the bearing groove 34 near the fixed plate 8 to come into contact. The partition plate 29 presses the contact plate 28 to move towards the fixed plate 8, which drives the rope assembly 25 to operate. The synchronous rod 36 drives the positioning rod 38 to descend. The positioning rod 38 drives the support shaft 40 and the grinding part 19 to descend through the linkage assembly 41, which can perform grinding and deburring operations on the vertical surface of the highway guardrail. By extending the second electric telescopic rod 10, the bearing block 32 can push the rotating plate 9 to deflect relative to the fixed plate 8 through the second spring 31, which can adjust the angle position of the grinding part 19 to adapt to the inclined surface of the highway guardrail, so as to carry out grinding and deburring operations. The second motor assembly 42 can drive one of the synchronous pulleys 39 to rotate, and drive the other two synchronous pulleys 39 to rotate through the synchronous belt 18. Through the cooperation of the elastic telescopic assembly 37 and the sliding member 13 on the vertical plate 17, the synchronous belt 18 is always kept in a taut state, ensuring stable power transmission.
