Description

Technical Field

[0001] The utility model relates to the technical field of processing corrugated guardrail plates, in particular to an integrated device for correcting and polishing corrugated guardrail plates. Background Art

[0002] Corrugated guardrails are anti-collision facilities on highways. They are mainly used to prevent out-of-control vehicles from running off the road. Different specifications are used according to different highway grades. Due to the influence of external forces, some corrugated guardrails are deformed, and the surface of the corrugated guardrails is corroded due to long-term erosion by high temperature, wind, sand, rain, snow and vehicle exhaust, which requires correction and grinding of the corrugated guardrails.

[0003] For example, a Chinese patent with publication number CN219378489U discloses an integrated device for correcting and grinding corrugated guardrail plates, comprising: a corrector, a moving mechanism and a grinding mechanism, wherein one side of the corrector is connected to one end of the moving mechanism, and the other end of the moving mechanism is connected to the grinding mechanism; the grinding mechanism comprises a support frame, a motor, a rotating shaft, a grinding wheel, a first belt and a second belt, the motor is arranged on the side of the support frame, the rotating shaft is arranged on the support frame, and the grinding wheel is arranged on the rotating shaft; by integrating the corrector, the moving mechanism and the grinding mechanism, the corrected guardrail plates can be directly moved to the grinding mechanism for grinding through the moving mechanism, thereby realizing automation and saving the time for manual handling and transportation of the corrected guardrail plates. The guardrail plates are automatically ground by the grinding mechanism, and the grinding wheel grinds the guardrail plates more evenly and the grinding quality is higher.

[0004] This patent grinds the corrugated guardrail plate by rotating the grinding wheel, and the grinding wheel is located in the concave position of the corrugated guardrail plate. However, the specifications of the corrugated guardrail plates are different when they are recycled, and different corrugated guardrail plates have different surface waveforms. The grinding wheel of this patent is not convenient to adjust the position, so it can only be used for the processing of corrugated guardrail plates of a specific specification, and its applicability is poor.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment:

[0025] Referring to Figures 1 to 4 , a combined device for correcting and grinding a corrugated guardrail plate disclosed by the present utility model includes a fixing frame 1. The fixing frame 1 is arranged in a U-shape with an open top. Two correcting pressure rollers 2 are sequentially arranged in the fixing frame 1 from top to bottom. The corrugated guardrail plate 100 passes through between the two correcting pressure rollers 2, and the outer surface of the correcting pressure roller 2 is in contact with the corrugated guardrail plate 100.

[0026] A grinding roller 3 is arranged in the upper half of the fixing frame 1, and the outer surface of the grinding roller 3 is in contact with the top surface of the corrugated guardrail plate 100. Three rotating rods 4 are rotatably penetrated through both opposite sides of the fixing frame 1. A connecting part 5 is arranged between the correcting pressure roller 2 or the grinding roller 3 and the corresponding rotating rod 4. A driving part 6 is arranged on one side of the fixing frame 1.

[0027] In this embodiment, a gap is left between the two correcting pressure rollers 2. The corrugated guardrail plate 100 first passes through the two correcting pressure rollers 2. The correcting pressure rollers 2 extrude the corrugated guardrail plate 100, so that the corrugated guardrail plate 100 is corrected. And under the rotation of the correcting pressure rollers 2, the corrugated guardrail plate 100 is subjected to frictional force and moves towards the grinding roller 3. The grinding roller 3 rotates to grind the top surface of the corrugated guardrail plate 100 (generally, only the side of the corrugated guardrail plate 100 facing the road needs to be ground). When placing the corrugated guardrail plate 100, place its side facing the road upwards.

[0028] In a further preferred embodiment of the present utility model, as Figure 4 shown, the connecting part 5 includes a square groove 51 opened at one end of the rotating rod 4. Side grooves 52 are opened at both ends of the correcting pressure roller 2 and the grinding roller 3. A square block 53 is slidably connected in the side groove 52. A part of the square block 53 is slidably inserted into the corresponding square groove 51. Cavities 54 are opened at the centers of the correcting pressure roller 2 and the grinding roller 3. A lead screw 55 is rotatably connected in the corresponding two side grooves 52 and the cavity 54. Both ends of the lead screw 55 are inserted into the corresponding square blocks 53, and the lead screw 55 is threadedly connected with the square blocks 53. One end of both the correcting pressure roller 2 and the grinding roller 3 is rotatably penetrated through an adjusting rod 56. The adjusting rod 56 extends into the cavity 54, and the adjusting rod 56 is connected with the lead screw 55 through a belt drive.

[0029] In this embodiment, when the rotating rod 4 rotates, it drives the square block 53 to rotate, thereby driving the correcting pressure roller 2 and the grinding roller 3 to rotate. Two sections of threads with opposite helix directions are arranged on the outer peripheral surface of the lead screw 55, and the two square blocks 53 are respectively threadedly connected to the two sections of threads. Therefore, the rotation of the lead screw 55 drives the two square blocks 53 to move in opposite directions.

[0030] When you want to replace the correction roller 2 or the grinding roller 3, turn the adjusting rod 56, and drive the screw 55 to rotate through the belt. The rotation of the screw 55 drives the two blocks 53 to move toward each other until the two blocks 53 are completely out of the square groove 51. At this time, the correction roller 2 or grinding roller 3 can be removed, and the correction roller 2 or grinding roller 3 matching the corrugated guardrail plate 100 to be processed can be replaced, so that the block 53 is aligned with the square groove 51, and then the adjusting rod 56 is rotated in the opposite direction to insert the two blocks 53 into the corresponding square groove 51, and the correction roller 2 or grinding roller 3 is connected to the rotating rod 4.

[0031] Furthermore, a hexagonal groove is formed on the end surface of the adjusting rod 56 , and a worker can insert a hexagonal wrench into the hexagonal groove to rotate the adjusting rod 56 .

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, the driving part 6 includes a supporting frame 61 fixedly connected to the side wall of the fixing frame 1, and a motor 62 is fixedly connected to one side of the supporting frame 61. The output end of the motor 62 is transmission-connected to one of the rotating rods 4, and the outer circumferences of the corresponding two rotating rods 4 connected to the correction roller 2 are fixedly sleeved with gears 63, and the two gears 63 are meshed with each other. One of the rotating rods 4 connected to the correction roller 2 and the rotating rod 4 connected to the grinding roller 3 are connected via belt transmission.

[0033] In this embodiment, the motor 62 drives the corresponding rotating rod 4 to rotate, and the rotating rod 4 drives the other two rotating rods 4 to rotate through the gear 63 or the belt, so that the three rotating rods 4 on one side of the fixed frame 1 rotate, and the three rotating rods 4 drive the correction roller 2 and the grinding roller 3 to rotate, and drive the three rotating rods 4 on the other side of the fixed frame 1 to rotate synchronously. The two correction rollers 2 rotate in opposite directions, which can drive the corrugated guardrail plate 100 to move horizontally.

[0034] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of electric push rods 7 are fixedly connected to the inner bottom wall of the fixed frame 1, and a support plate 8 is fixedly connected to the output ends of the plurality of electric push rods 7. The support plate 8 partially extends to directly below the grinding roller 3, and the top surface of the support plate 8 is in contact with the corrugated guardrail plate 100.

[0035] In this embodiment, the support plate 8 supports the corrugated guardrail plate 100 to prevent the corrugated guardrail plate 100 from being suspended in the air and tilted and deformed after being separated from the correction roller 2. The electric push rod 7 can adjust the height of the support plate 8 to adapt to corrugated guardrail plates 100 of different specifications.

[0036] In a further preferred embodiment of the present invention, Figure 3As shown, a circulation shell 9 is fixedly connected to the upper inner half of the fixed frame 1, and a plurality of dust collector heads 10 are fixedly penetrated at the bottom of the circulation shell 9. The dust collector heads 10 are located above the corrugated guardrail plate 100. An air pump 11 is fixedly connected to the side wall of the fixed frame 1, and the input end of the air pump 11 is communicated with the circulation shell 9.

[0037] In this embodiment, the air pump 11 works to make the vacuum head 10 inhale air, thereby sucking away the dust generated by grinding on the surface of the corrugated guardrail plate 100, keeping the surface of the corrugated guardrail plate 100 clean and tidy, making it convenient to directly spray the corrugated guardrail plate 100 later.

[0038] In a further preferred embodiment of the present invention, Figure 1 As shown, a collecting box 12 is fixedly connected to the side wall of the fixing frame 1, a filter screen 13 is horizontally fixedly connected to the center of the collecting box 12, the flow shell 9 is communicated with the upper half of the collecting box 12, and the input end of the air pump 11 is communicated with the lower half of the collecting box 12.

[0039] In this embodiment, the dust sucked away by the dust collector 10 enters the collection box 12 and is blocked by the filter 13, and the clean air flow passes through the filter 13 and is pumped out by the air pump 11, thereby preventing the dust from moving into the external environment.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
