Description

Technical Field

[0001] The utility model relates to the technical field related to traffic guardrails, in particular to a punching device for on-site maintenance of guardrail panels. Background Art

[0002] As traffic guardrails improve safety levels, guardrails previously had columns every 4 meters. To improve collision resistance, columns are now installed every 2 meters. Adding columns to existing structures is typically done on-site, requiring additional mounting holes.

[0003] The utility model patent with announcement number CN219052614U discloses a device for punching holes for on-site installation of guardrail panels. It belongs to the technical field related to traffic guardrails and aims to solve the problem of the existing technology of using a magnetic drill to manually drill holes on-site. Not only is the efficiency very low, but the holes are round and the margin of movement during installation is low. A slight misalignment will affect the installation speed, which is laborious and time-consuming. In addition, the position of the manually drilled holes cannot be guaranteed to be consistent, which affects the appearance after installation. The device includes a trolley frame, a gantry, a limit sliding mechanism and a positioning mechanism; a fixed support plate is fixed across the trolley frame, a gantry is fixed above the support plate, and a hydraulic punching machine is fixed in the middle of the gantry. The punch of the hydraulic punching machine punches holes vertically downward, and a cavity that cooperates with the punch is fixed in the middle of the support plate, and the cavity and the punch are aligned with the center of the punch; the corrugated groove to be punched in the guardrail panel is stuck in the cavity; the limit sliding mechanism is used to assist the sliding feed of the guardrail panel in the horizontal direction; and the positioning mechanism is used to position the feed of the guardrail panel in the horizontal direction. The utility model is suitable for on-site replacement and installation, and can flexibly move with the engineering team replacing the guardrail. The limiting sliding mechanism and the positioning mechanism accurately position the punching position in the feed direction. The punching hole shape is a waist-shaped hole with a large movable margin, and the installation is time-saving and labor-saving.

[0004] However, the above patent still has shortcomings: although the patent can open installation holes for the guardrail panels, it does not have the function of clamping and fixing the guardrail panels. When the guardrail panels are repaired and holes are opened, the guardrail panels themselves shake or move due to vibrations of the device and accidental touch by people, which can easily lead to large errors in the hole position.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 7 The present invention describes the above technical solution in detail through the following embodiments:

[0030] A punching device for on-site maintenance of guardrail panels, comprising: a base plate 1; a fixing box 2 is fixedly connected to the top of the fixing box 2, a top plate 3 is fixedly connected to the top of the top plate 3, a guardrail panel body 4 is provided on the top of the top plate 3, and plywood 5 is provided on both sides of the guardrail panel body 4, and both ends of one plywood 5 are provided with fixing plates 6, and the fixing plates 6 are fixedly connected to the top plate 3; a rotating mechanism 7 is provided inside the fixing box 2 for controlling the plywood 5 to clamp and fix the guardrail panel body 4; a displacement mechanism 8 is provided between the two fixing plates 6 for high-precision positioning drilling of the guardrail panel body 4, the user places the guardrail panel body 4 on the fixing box 2, and then controls the two plywood 5 to move toward the guardrail panel body 4 at the same time through the rotating mechanism 7, and then the guardrail panel body 4 is clamped and fixed by the cooperation of the two plywood 5, and finally the guardrail panel body 4 is opened by the displacement mechanism 8.

[0031] like Figure 3 and Figure 4The cam 12 is connected to the first gear 10 and the second gear 11 is connected to the second gear 11 by the cam 12. The cam 12 is connected to the first gear 10 and the second gear 11 is connected to the second gear 11 by the cam 12. The cam 12 is connected to the first gear 10 and the second gear 11 is connected to the second gear 11 by the cam 12. The cam 12 is connected to the first gear 10 and the second gear 11 is connected to the second gear 11 by the cam 12. The cam 12 is connected to the first gear 10 and the second gear 11 is connected to the second gear 11 by the cam 12. When the first gear 10 rotates, it drives the second gear 11 on both sides, and the second gear 11 drives the second rotating shaft 12. The second rotating shaft 12 drives the circular plate 13. The circular plate 13 pushes the cylindrical pin 15 through the arc groove 14 inside it, and the cylindrical pin 15 drives the moving block 16. The moving block 16 moves toward the guardrail plate body 4 at the same time through the cooperation of the fixed box 2, thereby driving the two clamping plates 5 to move toward the guardrail plate body 4 at the same time. The two clamping plates 5 cooperate to clamp and fix the guardrail plate body 4, which can avoid the occurrence of large hole position errors when the guardrail plate body 4 is repaired and opened, thereby improving the accuracy of the hole position. The existing punching device for on-site maintenance of guardrail plates does not have the function of clamping and fixing the guardrail plates when the guardrail plates are repaired and opened. The guardrail plate itself shakes or moves due to the vibration of the device and the accidental touch of the personnel, which can easily lead to the problem of large hole position errors.

[0032] like Figure 5 As shown, the power mechanism 17 includes: a worm wheel 18 is provided at the bottom of the first gear 10, the worm wheel 18 is fixed to the outer surface of the first rotating shaft 9, and a worm 19 is engaged with one side of the worm wheel 18; a third rotating shaft 20 is fixedly connected at the center of the worm 19, one end of the third rotating shaft 20 is rotatably connected to the fixed box 2, the other end of the third rotating shaft 20 passes through the fixed box 2 and extends to the motor 21, the motor 21 is fixedly connected to the fixed box 2, the third rotating shaft 20 is fixedly connected to the output end of the motor 21, the motor 21 is started, the output end of the motor 21 drives the third rotating shaft 20 to rotate, the third rotating shaft 20 rotates to drive the worm 19, the worm 19 drives the worm wheel 18 to rotate, and the cooperation between the worm 19 and the worm wheel 18 realizes a self-locking function.

[0033] like Figure 4 and Figure 6As shown, there are sliding grooves 22 on both sides of the movable block 16, and the fixed box 2 is fixedly connected with a limiting slide 23 near the sliding groove 22. The movable block 16 is slidably connected to the limiting slide 23 through the sliding groove 22, which can limit the movable block 16 so that the movable block 16 can slide flexibly inside the fixed box 2.

[0034] like Figure 7 As shown, the displacement mechanism 8 includes: a screw 24 is rotatably connected between the two fixed plates 6, one end of the screw 24 passes through the fixed plate 6 and extends to the turning handle 25, the turning handle 25 is fixedly connected to the screw 24, the outer surface of the screw 24 is threadedly connected to an adjusting block 26, the top of the adjusting block 26 is fixedly connected to a support frame 27, the end of the support frame 27 away from the adjusting block 26 is fixedly connected to a hydraulic cylinder 28, the telescopic end of the hydraulic cylinder 28 is fixedly connected to a hole punching machine 29, and a hole punching machine 29 is provided with a hole punching head 30 at the bottom; two sliding rods 31 are provided at the bottom of the screw 24, the two ends of the sliding rod 31 are fixedly connected to the fixed plate 6 respectively, the adjusting block 26 is slidably connected to the sliding rod 31, the user rotates the turning handle 25, the turning handle 25 drives the screw 24 to rotate, and the screw 24 While rotating, it drives the adjusting block 26, and the adjusting block 26 slides horizontally through the cooperation of the slide rod 31. The adjusting block 26 drives the support frame 27, and the support frame 27 drives the hydraulic cylinder 28. The hydraulic cylinder 28 drives the hole opening machine 29 and the hole opening head 30 to move, thereby achieving the purpose of adjusting the hole opening position. Finally, the hole opening machine 29 and the hydraulic cylinder 28 are started. While the hole opening machine 29 drives the hole opening head 30 to rotate at high speed, the telescopic end of the hydraulic cylinder 28 drives the hole opening machine 29 to move downward, thereby making the hole opening head 30 open a hole in the guardrail body 4. Not only can the hole opening machine 29 and the hole opening head 30 be controlled to move and adjust according to the position of the hole required, but also the accuracy of the displacement of the hole opening machine 29 and the hole opening head 30 is improved, thereby improving the practicality of the device.

[0035] like Figure 2 and Figure 4 As shown, a damping pad 32 is provided on one side of the splint 5 close to the guardrail body 4. The damping pad 32 is fixedly connected to the splint 5, thereby increasing the friction between the contact surface of the splint 5 and the guardrail body 4 and thus improving the stability of the clamping.

[0036] like Figure 1 and Figure 3 As shown, universal wheels 33 with braking function are provided at the four corners of the bottom of the base plate 1. The universal wheels 33 are fixedly connected to the base plate 1 respectively, making it convenient for users to move the device and further facilitate users to perform on-site maintenance of the guardrail body 4 on the road.

[0037] Working principle: The user places the guardrail body 4 on the fixed box 2, and then starts the motor 21. The output end of the motor 21 drives the third shaft 20 to rotate. The rotation of the third shaft 20 drives the worm 19, and the worm 19 drives the worm wheel 18 to rotate. The cooperation between the worm 19 and the worm wheel 18 realizes the self-locking function. The worm wheel 18 drives the first shaft 9, and the first shaft drives the first gear 10. While the first gear 10 rotates, it drives the second gears 11 on both sides. The second gear 11 drives the second shaft 12, and the second shaft 12 drives the circular plate 13. The circular plate 13 pushes the cylindrical pin 15 through the arc groove 14 inside it. The cylindrical pin 15 drives the moving block 16 to move. The block 16 moves toward the guardrail board body 4 at the same time through the cooperation of the fixing box 2, and then drives the two clamping plates 5 to move toward the guardrail board body 4 at the same time. The two clamping plates 5 cooperate to clamp and fix the guardrail board body 4, and can clamp and fix guardrail board bodies 4 of different sizes, avoiding the occurrence of large hole position errors when the guardrail board body 4 is repaired and opened, thereby improving the accuracy of the hole position. The existing punching device for on-site maintenance of guardrail boards does not have the function of clamping and fixing the guardrail boards. When the guardrail boards are repaired and opened, the guardrail boards themselves shake or displace due to the vibration of the device and the accidental touch of personnel, which can easily lead to the problem of large hole position errors in the openings.

[0038] The user rotates the handle 25, and the handle 25 drives the screw 24 to rotate. The rotation of the screw 24 drives the adjusting block 26, and the adjusting block 26 slides horizontally through the cooperation of the slide bar 31. The adjusting block 26 drives the support frame 27, and the support frame 27 drives the hydraulic cylinder 28. The hydraulic cylinder 28 drives the hole opening machine 29 and the hole opening head 30 to move, thereby achieving the purpose of adjusting the hole opening position. Finally, the hole opening machine 29 and the hydraulic cylinder 28 are started. While the hole opening machine 29 drives the hole opening head 30 to rotate at high speed, the telescopic end of the hydraulic cylinder 28 drives the hole opening machine 29 to move downward, thereby causing the hole opening head 30 to open a hole in the guardrail plate body 4. Not only can the hole opening machine 29 and the hole opening head 30 be controlled to move and adjust according to the position of the hole required, but also the accuracy of the displacement of the hole opening machine 29 and the hole opening head 30 is improved, thereby improving the practicality of the device.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
