The bottom of the workbench 1 is located directly below the top frame 14 and is equipped with two symmetrical A distributed cylinder 16, the output end of the cylinder 16 is arranged below the top frame 14, a cross plate 3 is movably inserted at both ends of the bracket 12, a clamping plate 32 is fixedly arranged at one end of the cross plate 3 close to the conveying roller 11, a rotating rod 33 is rotatably arranged at both ends of the bracket 12 below the cross plate 3, a screw rod 34 is inserted into the internal thread of the rotating rod 33 close to one end of the clamping plate 32, a vertically arranged push plate 35 is fixedly arranged at the bottom of the cross plate 3 close to one end of the clamping plate 32, the end of the screw rod 34 away from the rotating rod 33 is rotatably arranged on the push plate 35, and a linkage component is arranged between the rotating rod 33 and the top frame 14.

[0025] The linkage assembly includes a movable groove 17, which is opened at both ends of the workbench 1 and close to the middle end of the top frame 14. A bottom plate 15 is fixedly provided at the bottom of the top frame 14. Moving blocks 18 are fixedly provided at both ends of the bottom plate 15 close to the movable groove 17. The end of the moving block 18 away from the bottom plate 15 passes through the movable groove 17 and is fixedly provided with a vertically arranged toothed plate 19. A driving gear 21 is meshed at the teeth of the toothed plate 19. A first transmission shaft 22 is fixedly provided at the center of the driving gear 21. A second transmission shaft 37 parallel to the first transmission shaft 22 is provided on the outer wall of the bracket 12 near the rotating rod 33. The second transmission shaft 37 is connected to the rotating rod 33 by two meshing bevel gears 38, and the second transmission shaft 37 is connected to the first transmission shaft 22 by a belt 4.

[0026] By adopting the above technical solution, when the tooth plate 19 moves up along with the base plate 15 through the moving block 18, the tooth plate 19 will drive the driving gear 21 to rotate. At this time, the rotating rod 33 is driven to rotate through the first transmission shaft 22, the belt 4, the second transmission shaft 37 and the two meshing bevel gears 38, so that the screw rod 34 threadedly inserted on the rotating rod 33 pushes the cross plate 3 to move through the push plate 35. At this time, the two cross plates 3 will move toward each other and clamp the guardrail plate lifted by the top frame 14 at the same time.

[0028] By adopting the above technical solution, the bearing 36 is provided so that the screw rod 34 can drive the push plate 35 to move normally.

[0029] An adjusting screw 31 is rotatably provided at the middle end of the transverse plate 3, one end of the adjusting screw 31 is fixedly provided on a clamping plate 32, and two symmetrically distributed limiting rods are fixedly provided on one end of the clamping plate 32 close to the transverse plate 3, and the limiting rods are movably inserted on the transverse plate 3.

[0030] By adopting the above technical solution, the adjusting screw 31 can adjust the distance of the clamping plate 32, so that when the cross plate 3 moves, the clamping plate 32 can be driven to move to fully clamp the guardrail.

[0031] A support frame 2 is fixedly provided on the top of the outer wall of the workbench 1 near the movable groove 17, and the first transmission shaft 22 passes through the support frame 2. A slide bar 23 is fixedly provided on the side of the tooth plate 19 near the workbench 1, and the slide bar 23 can be slidably set on the workbench 1 along with the tooth plate 19.

[0032] By adopting the above technical solution, the support frame 2 can stably rotate the driving gear 21 and the first transmission shaft 22, and the slide bar 23 can stably move the tooth plate 19 vertically up and down.

[0033] A support block 41 is fixedly disposed on the outer wall of the workbench 1 and the bracket 12 near the first transmission shaft 22 and the second transmission shaft 37 , and the first transmission shaft 22 and the second transmission shaft 37 both movably penetrate the support block 41 .

[0034] By adopting the above technical solution, the support block 41 can support the first transmission shaft 22 and the second transmission shaft 37 to enable them to rotate stably.

[0035] An L-shaped baffle plate 5 is fixedly provided on one side of the top frame 14 close to the material discharging of the conveying roller 11 , and the top of a vertical end of the baffle plate 5 is higher than the top of the top frame 14 .

[0036] By adopting the above technical solution, the baffle 5 can shield the guardrail being transported, so that it stops moving after moving to the drilling position, which is convenient for subsequent lifting and drilling operations.

[0037] A rubber buffer pad 51 is provided on the clamping plate 32 and the top frame 14 at one side close to the guardrail to be clamped.

[0038] By adopting the above technical solution, the rubber buffer pad 51 is provided to avoid hard contact with the guardrail plate, thereby preventing the guardrail plate from being damaged.

[0039] Working principle: In actual use, the staff can place the guardrail plate to be drilled from the conveying roller 11 on the side away from the baffle 5. The rotation of the conveying roller 11 will drive the guardrail plate to gradually move to the bottom of the bracket 12. As the guardrail plate moves, it will abut against the baffle 5. At this time, the cylinder 16 can be driven, and the cylinder 16 will push the top frame 14 upward through the bottom plate 15. At this time, the top frame 14 will push the guardrail plate blocked by the baffle 5 to contact it, thereby lifting it up and making it separate from the conveying roller 11. At this time, the guardrail plate will stop moving. In the process of the top frame 14 moving upward, the tooth plate 19 is driven to move upward through the moving block 18. At this time, the tooth plate 19 will drive the driving gear 21 meshed with it to rotate. The driving gear 21 drives the rotating rod 33 to rotate through the first transmission shaft 22, the belt 4, the second transmission shaft 37 and the two meshing bevel gears 38, so that the screw rod 34 threaded on the rotating rod 33 passes through the push plate 3 5 pushes the cross plate 3 to move. At this time, the two cross plates 3 will move toward each other and clamp the guardrail plate lifted by the top frame 14 to avoid deviation of the drilling device body 13 during drilling. After the drilling is completed, the cylinder 16 drives the top frame 14 to move downward through the bottom plate 15. At this time, the toothed plate 19 will drive the driving gear 21 to rotate in the opposite direction. At this time, the two clamping plates 32 are away from the guardrail plate at the same time. As the top frame 14 moves downward, the guardrail plate can be contacted with the conveying roller 11 again. As the bottom plate 15 moves downward, the top of the baffle 5 also moves below the conveying roller 11. At this time, the guardrail plate after drilling is completed will be normally conveyed by the conveying roller 11, so as to be automatically unloaded. The subsequent guardrail plate can be installed with the above operation for drilling. Through the above operation, the guardrail plate can be automatically drilled and unloaded at the same time, which can greatly reduce the steps of drilling, reduce the labor of the staff and improve the drilling efficiency, thereby increasing the production rate.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
