Description

Technical Field

[0001] This invention relates to the field of steel structure processing technology, and in particular to a steel structure grinding device. Background Technology

[0002] Steel structures are one of the main types of building structures. Replacing concrete structures with steel structures can reduce the amount of sand, stone, and cement used, thus mitigating the damage to non-renewable resources. Steel structures require grinding during fabrication.

[0003] During the grinding process of steel structures, the temperature of the upper surface of the steel structure and the grinding disc will rise rapidly. If the upper surface of the steel structure and the grinding disc are not cooled down in time, it will lead to damage to the steel structure and the grinding disc, reducing their service life. Therefore, a steel structure grinding device is proposed. Summary of the Invention

[0004] The present invention aims to solve the technical problem of how to reduce the temperature of the steel structure and the grinding disc during the grinding process, and prevent damage to the steel structure and the grinding disc, by providing a steel structure grinding device.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A steel structure grinding device includes four support columns, a base, two support plates, a top plate, two vertical plates, a fixing mechanism, a grinding device, a laser detection device, an air blowing cooling device, and a control panel.

[0007] The base is horizontally positioned above the four support columns, and the bottom of the base is fixedly connected to the top of each of the four support columns.

[0008] Two support plates are vertically symmetrically positioned above the base, arranged in a left-right configuration, with the bottom of each support plate fixedly connected to the top of the base.

[0009] The top plate is horizontally positioned above the two support plates. The bottom surface of the top plate has a groove, and the bottom of the top plate is fixedly connected to the top of the two support plates respectively.

[0010] Two vertical plates are symmetrically positioned above the base, between two support plates, and the bottoms of the two vertical plates are fixedly connected to the bottom of the base.

[0011] The fixing mechanism is located above the base, between the two vertical plates, and is connected to the two vertical plates.

[0012] The grinding device is located above the base and below the top plate, and is connected to the top plate.

[0013] The laser inspection device is located above the base and below the grinding device, and is connected to two vertical plates.

[0014] The air blowing cooling device is located above the base and behind the laser detection device. The air blowing device is connected to the base, the laser detection device, and the grinding device.

[0015] The control panel is located at the front of the base and is fixedly connected to the base. The control panel is electrically connected to the fixing mechanism, the grinding device, and the laser detection device.

[0016] When using this device, the staff fixes the square steel structure in place using the fixing mechanism. Then, the staff starts the grinding device through the control panel and grinds the entire surface of the steel structure. During the grinding process, the grinding effect of the steel structure surface is detected by a laser detection device, and the temperature of the steel structure surface is reduced by an air cooling device.

[0017] Furthermore, the two vertical plates are fixedly connected to the base with bolts.

[0018] This allows the steel structure to be stably fixed in place, and the horizontal plate to move stably.

[0019] Furthermore, the top plate is fixedly connected to the two support plates by welding.

[0020] This allows the mounting box to move and operate the grinder.

[0021] Furthermore, the fixing mechanism includes two first cylinders, two clamping plates, and two protrusions.

[0022] Two first cylinders are positioned above the base, symmetrically arranged between two vertical plates. The extension and retraction directions of the two first cylinders are horizontal, and the two first cylinders are fixedly connected to the two vertical plates respectively.

[0023] The two clamps are perpendicular to the telescopic ends of the two first cylinders, respectively, and are set above the base, on the opposite sides of the telescopic ends of the two first cylinders. The two clamps are fixedly connected to the telescopic ends of the two first cylinders respectively.

[0024] Two protrusions are located on the top of the base, symmetrically positioned on the opposite sides of the two clamping plates, and are fixedly connected to the two clamping plates respectively.

[0025] When it is necessary to fix the steel structure, the workers insert the square steel into a protrusion. Then, the workers activate the two first cylinders through the control panel. The extension and retraction ends of the two first cylinders drive the two clamps to move towards each other. The two clamps drive the two protrusions to move towards each other. The two clamps and the two protrusions work together to firmly fix the steel structure. Then, the workers close the first cylinders through the control panel.

[0026] Furthermore, there are gaskets on the opposite sides of both clamps.

[0027] This allows the steel structure to be stably fixed.

[0028] Furthermore, the grinding device includes a first motor, a first threaded rod, a slider, a second cylinder, a mounting box, a grinding machine, and a grinding disc.

[0029] The first motor is located on the side of the top plate. The shaft of the first motor passes through the top plate. The axis of the shaft of the first motor is parallel to the extension and retraction direction of the extension and retraction end of the first cylinder. The first motor is fixedly connected to the top plate.

[0030] The first threaded rod is horizontally disposed at the lower part of the top plate and is located in the groove. The axis of the first threaded rod coincides with the axis of the rotating shaft of the first motor. One end of the first threaded rod is fixedly connected to the rotating shaft of the first motor, and the other end is rotatably connected to the top plate.

[0031] The slider is vertically positioned at the bottom of the top plate and sleeved on the outside of the first threaded rod. The slider and the first threaded rod are helically connected.

[0032] The second cylinder is located below the slider. The extension and retraction direction of the second cylinder is vertical. The top of the second cylinder is fixedly connected to the bottom of the slider.

[0033] The mounting box is located below the second cylinder, and the top of the mounting box is fixedly connected to the telescopic end of the second cylinder.

[0034] The grinder is located inside the mounting box, near the top inner wall of the mounting box. The axis of the grinder's rotation is vertical, and the shaft of the grinder runs vertically through the bottom of the mounting box. The top of the grinder is fixedly connected to the top inner wall of the mounting box.

[0035] The grinding disc is positioned horizontally below the mounting box, with its axis coinciding with the axis of the grinding machine's rotating shaft. The grinding disc is fixedly connected to the rotating shaft of the grinding machine.

[0036] When the steel structure needs to be polished, the operator starts the polisher and the second cylinder via the control panel. The polisher operates, and its rotating shaft drives the polishing disc to rotate. The second cylinder operates, and its telescopic end moves the mounting box downwards. The mounting box moves the polisher downwards, and the polisher moves the polishing disc downwards. When the polishing disc contacts the upper surface of the steel structure, the operator closes the second cylinder via the control panel, and the polishing work can then begin.

[0037] When it is necessary to thoroughly grind the upper surface of the steel structure, the staff controls the first motor shaft to rotate forward through the control panel. The first motor shaft drives the first threaded rod to rotate forward, the first threaded rod drives the slider to move to the right, the slider drives the second cylinder to move to the right, the extension end of the second cylinder drives the mounting box to move to the right, the mounting box drives the grinder to move to the right, the grinder drives the grinding disc to move to the right, and the grinding disc can then thoroughly grind the upper surface of the steel structure.

[0038] Furthermore, the laser detection device includes two round rods, a horizontal plate, two mounting blocks, a laser emitter, a receiver, a connecting rod, a telescopic rod, and a spring.

[0039] Two round rods are arranged symmetrically on the upper part of the base, one in front of the other, between the two vertical plates and below the first cylinder. The two ends of the two round rods are fixedly connected to the two vertical plates respectively.

[0040] The horizontal plate is positioned above the base, between the two vertical plates. The front and rear parts of the horizontal plate are respectively fitted onto the outside of the two round rods, and the horizontal plate is slidably connected to the two round rods along the two round rods.

[0041] Two mounting blocks are vertically positioned above the horizontal plate, arranged one in front of the other, with the bottom of each mounting block fixedly connected to the top of the horizontal plate.

[0042] The laser emitter is positioned above the mounting block near the front side, and the laser emitter emits light at an angle downwards. The laser emitter is fixedly connected to the mounting block on the front side.

[0043] The receiver is positioned above the rear mounting block, and is at the same horizontal level as the laser emitter. The receiver is fixedly connected to the rear mounting block.

[0044] The connecting rod is positioned horizontally at the rear of the mounting box, perpendicular to the rear surface of the mounting box, and is fixedly connected to the rear of the mounting box.

[0045] The telescopic rod is vertically positioned above the horizontal plate, below the connecting rod, and behind the receiver. The bottom end of the telescopic rod is fixedly connected to the top of the horizontal plate, and the top end of the telescopic rod is fixedly connected to the connecting rod.

[0046] The spring is vertically positioned above the horizontal plate and sleeved on the outside of the telescopic rod. The bottom of the spring is fixedly connected to the top of the horizontal plate, and the top of the spring is fixedly connected to the connecting rod.

[0047] When it is necessary to inspect the grinding effect on the upper surface of the steel structure, the connecting rod drives the telescopic rod and spring to move to the right. The telescopic rod and spring drive the horizontal plate to move to the right. The horizontal plate drives the two mounting blocks to move to the right. The two mounting blocks drive the laser emitter and receiver to move to the right. The operator starts the laser emitter through the control panel. The laser emitter emits a laser beam that shines on the upper surface of the steel structure. The upper surface of the steel structure refracts the laser beam. After refraction, the laser beam is received by the receiver. The receiver transmits the laser signal to the control panel. The operator can then measure and analyze the characteristics of the reflected light through the control panel, thereby inspecting the grinding effect on the upper surface of the steel structure.

[0048] Furthermore, the laser emitter illuminates the steel structure surface at the point on the left side of the grinding disc.

[0049] This allows the laser emitted by the laser emitter to be directed at the polished surface of the steel structure.

[0050] Furthermore, the air-blowing cooling device includes a cylinder, piston, piston rod, cooling box, suction pipe, exhaust hose, air-blowing head, and two one-way valves.

[0051] The cylinder body is located above the base and behind the vertical plate, with the bottom of the cylinder body fixedly connected to the top of the base.

[0052] The piston is vertically positioned inside the cylinder and slides along the inner wall of the cylinder.

[0053] The piston rod is positioned laterally on the left side of the cylinder body. One end of the piston rod is fixedly connected to the piston, and the other end of the piston rod passes through the left side of the cylinder body and is fixedly connected to the cross plate.

[0054] The cooling box is located above the base, on the side of the cylinder away from the piston rod, and is fixedly connected to the top of the base.

[0055] The intake pipe is horizontally positioned above the base, between the cylinder and the cooling box. One end of the intake pipe is connected to the cooling box, and the other end is connected to the cylinder.

[0056] The air blowing head is angled and positioned at the bottom of the mounting box, penetrating through the bottom of the mounting box, and is fixedly connected to the mounting box.

[0057] The exhaust hose is located at the top of the cylinder block. One end of the exhaust hose is connected to the cylinder block, and the other end of the exhaust hose passes through the mounting box and is connected to the blower head.

[0058] Two one-way valves are respectively installed inside the intake pipe and the exhaust hose, and the two one-way valves are fixedly connected to the intake pipe and the exhaust hose respectively.

[0059] When it is necessary to reduce the surface temperature of the steel structure, the piston rod moves the piston to the left, and the piston drives the cold air in the cooling box to enter the cylinder through the suction pipe and the one-way valve. The piston rod then moves the piston to the right, and the piston pushes the cold air in the cylinder through the one-way valve, the exhaust hose, and the blower head to blow onto the surface of the steel structure. The blown-out cold air reduces the surface temperature of the steel structure and blows away the debris generated during grinding.

[0060] Furthermore, it includes several bristles, which are vertically arranged at the bottom of the horizontal plate. The upper ends of the bristles are fixedly connected to the bottom of the horizontal plate, and the lower ends of the bristles are tightly attached to the base.

[0061] Several brush bristles clean the debris that falls onto the upper surface of the base, causing the debris to gather together and making it easier for staff to remove it later.

[0062] The beneficial effects of this invention are:

[0063] 1. This invention, by setting up a cooling box, suction pipe, cylinder, air blowing head, plug rod and other structures, enables cold air to be blown onto the upper surface of the steel structure and the grinding disc during the grinding process, thereby reducing the temperature of the steel structure and the grinding disc, preventing damage to the steel structure or the grinding disc, and the blown cold air can also blow away the debris generated during grinding.

[0064] 2. This invention, by setting up two mounting blocks, a laser emitter, a receiver, and other structures, enables the laser emitter to emit laser light onto the upper surface of the steel structure, the receiver to receive the refracted laser light, and then transmit the data to the control panel, making it convenient for staff to inspect the polishing effect of the steel structure.

[0065] 3. By setting up a connecting rod, telescopic rod, spring and other structures, the present invention compresses the telescopic rod and spring when the mounting box moves the grinding machine and grinding disc down to grind the steel structure. This allows the vibration generated during grinding of the steel structure to be transmitted to the telescopic rod and spring, thereby buffering and reducing the vibration.

[0066] 4. By setting up a horizontal plate and several brush bristles, the present invention enables the brush bristles to sweep away the debris that falls onto the base during the polishing of the steel structure and the debris blown onto the base by the air blown head, so that the debris is concentrated together and convenient for subsequent workers to remove the debris.

[0073] like Figure 1-4 As shown, the technical solution adopted by the present invention to solve its technical problem is:

[0074] A steel structure grinding device includes four support columns 1, a base 2, two support plates 3, a top plate 4, two vertical plates 5, a fixing mechanism, a grinding device, a laser detection device, an air blowing cooling device, and a control panel 33.

[0075] The base 2 is horizontally positioned above the four support columns 1, and the bottom of the base 2 is fixedly connected to the top of the four support columns 1 respectively.

[0076] Two support plates 3 are vertically symmetrically arranged above the base 2, in a left-right arrangement, and the bottom of the two support plates 3 are fixedly connected to the top of the base 2 respectively.

[0077] The top plate 4 is horizontally positioned above the two support plates 3. The bottom surface of the top plate 4 has a groove, and the bottom of the top plate 4 is fixedly connected to the top of the two support plates 3 respectively.

[0078] Two vertical plates 5 are arranged symmetrically above the base 2, between two support plates 3, and the bottoms of the two vertical plates 5 are fixedly connected to the bottom of the base 2 respectively.

[0079] The fixing mechanism is located above the base 2, between the two vertical plates 5, and is connected to the two vertical plates 5.

[0080] The grinding device is located above the base 2 and below the top plate 4, and is connected to the top plate 4.

[0081] The laser detection device is located above the base 2 and below the grinding device, and is connected to the two vertical plates 5.

[0082] The air blowing cooling device is located above the base 2 and behind the laser detection device. The air blowing device is connected to the base 2, the laser detection device, and the grinding device.

[0083] The control panel 33 is located at the front of the base 2 and is fixedly connected to the base 2. The control panel 33 is electrically connected to the fixing mechanism, the grinding device, and the laser detection device.

[0084] When using this device, the staff fixes the square steel structure using the fixing mechanism, and then starts the grinding device through the control panel 33. The grinding device grinds the entire surface of the steel structure. During the grinding process, the grinding effect of the steel structure surface is detected by the laser detection device, and the temperature of the steel structure surface is reduced by the air cooling device.

[0085] The two vertical plates 5 are fixedly connected to the base 2 by bolts.

[0086] This allows the steel structure to be stably fixed in place, and the horizontal plate 17 to move stably.

[0087] The top plate 4 is fixedly connected to the two support plates 3 by welding.

[0088] This enables the mounting box 13 to drive the grinder 14 to move and operate.

[0089] The fixing mechanism includes two first cylinders 6, two clamping plates 7, and two protrusions 8.

[0090] Two first cylinders 6 are positioned above the base 2, symmetrically arranged between the two vertical plates 5. The extension and retraction directions of the two first cylinders 6 are horizontal, and the two first cylinders 6 are fixedly connected to the two vertical plates 5 respectively.

[0091] The two clamping plates 7 are perpendicular to the telescopic ends of the two first cylinders 6, respectively, and are set above the base 2, on the opposite sides of the telescopic ends of the two first cylinders 6. The two clamping plates 7 are fixedly connected to the telescopic ends of the two first cylinders 6 respectively.

[0092] Two protrusions 8 are positioned above the base 2 and symmetrically positioned on opposite sides of the two clamping plates 7. The two protrusions 8 are fixedly connected to the two clamping plates 7 respectively.

[0093] When it is necessary to fix the steel structure, the staff inserts the square steel into a protrusion 8, and then the staff starts the two first cylinders 6 through the control panel 33. The extension and retraction ends of the two first cylinders 6 drive the two clamps 7 to move towards each other. The two clamps 7 drive the two protrusions 8 to move towards each other. The two clamps 7 and the two protrusions 8 work together to firmly fix the steel structure. Then the staff closes the first cylinders 6 through the control panel 33.

[0094] There are gaskets on the opposite sides of both clamps 7.

[0095] This allows the steel structure to be stably fixed.

[0096] The grinding device includes a first motor 9, a first threaded rod 10, a slider 11, a second cylinder 12, a mounting box 13, a grinding machine 14, and a grinding disc 15.

The axis of the shaft of the first motor 9 is parallel to the extension and retraction direction of the extension and retraction end of the first cylinder 6. The first motor 9 is fixedly connected to the top plate 4.

[0098] The first threaded rod 10 is horizontally disposed at the lower part of the top plate 4 and is located in the groove. The axis of the first threaded rod 10 coincides with the axis of the rotating shaft of the first motor 9. One end of the first threaded rod 10 is fixedly connected to the rotating shaft of the first motor 9, and the other end is rotatably connected to the top plate 4.

[0099] The slider 11 is vertically positioned at the lower part of the top plate 4 and sleeved on the outside of the first threaded rod 10. The slider 11 and the first threaded rod 10 are spirally connected.

[0100] The second cylinder 12 is located below the slider 11. The extension and retraction direction of the extension and retraction end of the second cylinder 12 is vertical. The top of the second cylinder 12 is fixedly connected to the bottom of the slider 11.

[0101] The mounting box 13 is located below the second cylinder 12, and the top of the mounting box 13 is fixedly connected to the telescopic end of the second cylinder 12.

[0102] The grinder 14 is located inside the mounting box 13, near the top inner wall of the mounting box 13.

The top of the grinder 14 is fixedly connected to the top inner wall of the mounting box 13.

[0103] The grinding disc 15 is horizontally positioned below the mounting box 13, and the axis of the grinding disc 15 coincides with the axis of the rotating shaft of the grinder 14. The grinding disc 15 is fixedly connected to the rotating shaft of the grinder 14.

[0104] When the steel structure needs to be polished, the operator starts the polisher 14 and the second cylinder 12 through the control panel 33. The polisher 14 works, and the rotating shaft of the polisher 14 drives the polishing disc 15 to rotate.

The mounting box 13 drives the polisher 14 to move down, and the polisher 14 drives the polishing disc 15 to move down. When the polishing disc 15 contacts the upper surface of the steel structure, the operator closes the second cylinder 12 through the control panel 33, and the polishing work on the steel structure can be carried out.

[0105] When it is necessary to thoroughly grind the upper surface of the steel structure, the operator controls the first motor 9 to rotate forward through the control panel 33.

[0107] Two round rods 16 are arranged symmetrically above the base 2, one in front of the other, between the two vertical plates 5, and below the first cylinder 6. The two ends of the two round rods 16 are fixedly connected to the two vertical plates 5 respectively.

[0108] The horizontal plate 17 is positioned horizontally above the base 2, between the two vertical plates 5.

[0109] Two mounting blocks 18 are vertically positioned above the horizontal plate 17, arranged in a front-to-back pattern, with the bottoms of the two mounting blocks 18 fixedly connected to the top of the horizontal plate 17 respectively.

[0110] The laser emitter 19 is positioned above the mounting block 18 near the front side. The laser emitter 19 emits light at an angle downwards and is fixedly connected to the mounting block 18 on the front side.

[0111] The receiver 20 is positioned above the rear mounting block 18. The receiver 20 and the laser emitter 19 are on the same horizontal plane, and the receiver 20 is fixedly connected to the rear mounting block 18.

[0112] The connecting rod 21 is horizontally positioned at the rear of the mounting box 13, perpendicular to the rear surface of the mounting box 13, and is fixedly connected to the rear part of the mounting box 13.

[0114] Spring 23 is vertically positioned above horizontal plate 17 and sleeved on the outside of telescopic rod 22. The bottom of spring 23 is fixedly connected to the top of horizontal plate 17, and the top of spring 23 is fixedly connected to connecting rod 21.

[0115] When it is necessary to inspect the grinding effect of the upper surface of the steel structure, the connecting rod 21 drives the telescopic rod 22 and spring 23 to move to the right. The telescopic rod 22 and spring 23 drive the horizontal plate 17 to move to the right. The horizontal plate 17 drives the two mounting blocks 18 to move to the right. The two mounting blocks 18 drive the laser emitter 19 and receiver 20 to move to the right. The operator starts the laser emitter 19 through the control panel 33. The laser emitter 19 emits a laser beam that shines on the upper surface of the steel structure. The upper surface of the steel structure refracts the laser beam. After refraction, the laser beam is received by the receiver 20. The receiver 20 transmits the laser signal to the control panel 33. The operator can then measure and analyze the characteristics of the reflected light through the control panel 33 to inspect the grinding effect of the upper surface of the steel structure.

[0116] The laser emitter 19 illuminates the steel structure surface at the point on the left side of the polishing disc 15.

[0117] This allows the laser emitted by the laser emitter 19 to be directed at the polished upper surface of the steel structure.

[0118] The air-blowing cooling device includes a cylinder 24, a piston 25, a piston rod 26, a cooling box 27, an air intake pipe 28, an exhaust hose 29, an air blowing head 30, and two one-way valves 31.

[0119] The cylinder body 24 is located above the base 2 and behind the vertical plate 5. The bottom of the cylinder body 24 is fixedly connected to the top of the base 2.

[0120] The piston 25 is vertically disposed inside the cylinder 24, and the piston 25 is slidably connected to the cylinder 24 along the inner wall of the cylinder 24.

[0121] The piston rod 26 is horizontally disposed on the left side of the cylinder body 24. One end of the piston rod 26 is fixedly connected to the piston 25, and the other end of the piston rod 26 passes through the left side of the cylinder body 24 and is fixedly connected to the cross plate 17.

[0122] The refrigeration box 27 is located above the base 2, on the side of the cylinder 24 away from the piston rod 26, and the refrigeration box 27 is fixedly connected to the top of the base 2.

[0123] The intake pipe 28 is horizontally positioned above the base 2, between the cylinder 24 and the cooling box 27. One end of the intake pipe 28 is connected to the cooling box 27, and the other end is connected to the cylinder 24.

[0124] The air blowing head 30 is obliquely disposed at the lower part of the mounting box 13, and the air blowing head 30 penetrates through the bottom of the mounting box 13 and is fixedly connected to the mounting box 13.

[0125] The exhaust hose 29 is located on the upper part of the cylinder 24. One end of the exhaust hose 29 is connected to the cylinder 24, and the other end of the exhaust hose 29 passes through the mounting box 13 and is connected to the air blower 30.

[0126] Two one-way valves 31 are respectively installed inside the intake pipe 28 and the exhaust hose 29, and the two one-way valves 31 are fixedly connected to the intake pipe 28 and the exhaust hose 29 respectively.

[0127] When it is necessary to lower the surface temperature of the steel structure, the piston rod 26 drives the piston 25 to move to the left. The piston 25 then draws the cold air from the cooling box 27 into the cylinder 24 through the suction pipe 28 and the one-way valve 31. The piston rod 26 then drives the piston 25 to move to the right. The piston 25 pushes the cold air from the cylinder 24 through the one-way valve 31, the exhaust hose 29, and the air blower 30, blowing it onto the surface of the steel structure. The blown-out cold air lowers the surface temperature of the steel structure and blows away the debris generated during grinding.

[0128] It includes several bristles 32, which are vertically arranged at the bottom of the horizontal plate 17. The upper ends of the several bristles 32 are fixedly connected to the bottom of the horizontal plate 17, and the lower ends of the several bristles 32 are tightly attached to the base 2.

[0129] Several bristles 32 clean the debris that falls onto the upper surface of the base 2, causing the debris to gather together and making it easier for staff to remove the debris later.

[0130] Working principle: When the operator uses this device, the operator inserts the square steel into a protrusion 8, and then starts the two first cylinders 6 through the control panel 33. The extension and retraction ends of the two first cylinders 6 drive the two clamping plates 7 to move towards each other. The two clamping plates 7 drive the two protrusions 8 to move towards each other. The two clamping plates 7 and the two protrusions 8 work together to firmly fix the steel structure. Then the operator closes the first cylinders 6 through the control panel 33.

[0131] Before polishing, initial preparations should be made so that the polishing disc 15, laser emitter 19, receiver 20, and several brush bristles 32 are all located on the far left. The operator controls the first motor 9 to rotate in reverse through the control panel 33. The first motor 9 rotates in reverse, causing the first threaded rod 10 to rotate in reverse. The first threaded rod 10 causes the slider 11 to move to the left. The slider 11 causes the mounting box 13 to move to the left. The mounting box 13 causes the connecting rod 21 to move to the left, causing the polishing machine 14 to move to the left. The polishing machine 14 causes the polishing disc 15 to move to the left, so that the polishing disc 15 is located on the far left.

[0132] When the mounting box 13 moves the connecting rod 21 to the left, the connecting rod 21 moves the telescopic rod 22 and the spring 23 to the left. The telescopic rod 22 and the spring 23 move the horizontal plate 17 to the left. The horizontal plate 17 moves several brush bristles 32 to the left, moves the two mounting blocks 18 to the left, moves the stopper rod 26 to the left, and moves the piston 25 to the left. The piston 25 moves the cold air in the refrigeration box 27 through the suction pipe 28 and the one-way valve 31 into the cylinder 24.

[0133] When the horizontal plate 17 moves the two mounting blocks 18 to the left, the two mounting blocks 18 move the laser emitter 19 and receiver 20 to the left, so that the laser emitter and receiver are located on the far left.

[0134] When the horizontal plate 17 moves several bristles 32 to the left, the bristles are also positioned on the far left, completing the initial preparation work.

[0135] When the steel structure needs to be polished, the operator starts the polisher 14 and the second cylinder 12 through the control panel 33. The polisher 14 works, and the rotating shaft of the polisher 14 drives the polishing disc 15 to rotate. The second cylinder 12 works, and the telescopic end of the second cylinder 12 drives the mounting box 13 to move down. The mounting box 13 drives the connecting rod 21 to move down, which in turn drives the polisher 14 to move down. The polisher 14 drives the polishing disc 15 to move down. When the polishing disc 15 contacts the upper surface of the steel structure, the operator closes the second cylinder 12 through the control panel 33, and the polishing work on the steel structure can then be carried out.

[0136] When the mounting box 13 moves the connecting rod 21 downward, the connecting rod 21 compresses the telescopic rod 22 and the spring 23, so that the vibration generated by the grinding disc 15 when grinding the steel structure can be buffered by the telescopic rod 22 and the spring 23.

[0137] When it is necessary to thoroughly grind the upper surface of the steel structure, the operator controls the first motor 9 to rotate forward through the control panel 33. The first motor 9 drives the first threaded rod 10 to rotate forward, the first threaded rod 10 drives the slider 11 to move to the right, the slider 11 drives the second cylinder 12 to move to the right, the telescopic end of the second cylinder 12 drives the mounting box 13 to move to the right, the mounting box 13 drives the connecting rod 21 to move to the right, and drives the grinder 14 to move to the right. The grinder 14 drives the grinding disc 15 to move to the right, and the grinding disc 15 can then thoroughly grind the upper surface of the steel structure.

[0138] When the mounting box 13 moves the connecting rod 21 to the right, the connecting rod 21 moves the telescopic rod 22 and the spring 23 to the right. The telescopic rod 22 and the spring 23 move the horizontal plate 17 to the right. The horizontal plate 17 moves several brush bristles 32 to the right, moves the two mounting blocks 18 to the right, moves the stopper rod 26 to the right, and moves the piston 25 to the right. The piston 25 pushes the cold air in the cylinder 24 to pass through the one-way valve 31, the exhaust hose 29, and the air blower 30 to blow onto the surface of the steel structure. The blown cold air reduces the temperature of the upper surface of the steel structure and the grinding disc, and blows away the debris generated during grinding.

[0139] When the horizontal plate 17 moves the two mounting blocks 18 to the right, the two mounting blocks 18 move the laser emitter 19 and receiver 20 to the right. The operator starts the laser emitter 19 through the control panel 33. The laser emitter 19 emits a laser that shines on the upper surface of the steel structure. The upper surface of the steel structure refracts the laser, and the refracted laser is received by the receiver 20. The receiver 20 transmits the laser signal to the control panel 33, and the operator can then measure and analyze the characteristics of the reflected light through the control panel 33 to detect the polishing effect on the upper surface of the steel structure.

[0140] When the horizontal plate 17 moves several brush bristles 32 to the right, the brush bristles 32 sweep away the debris that falls on the upper surface of the base 2, so that the debris is concentrated together, making it easier for the staff to remove the debris later.

[0141] The above embodiments are only some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.
