Abstract
Description
Technical Field
[0001] This utility model relates to the field of guardrail production technology, specifically to an automatic palletizing device for a guardrail production line. Background Technology
[0002] Guardrails are road safety protection facilities, usually installed on both sides or in the median strip of highways, expressways, bridges, tunnels, etc. They are widely used on roads of various grades, including urban roads, national highways, provincial highways, and expressways, as well as dangerous sections of mountain roads, curves, and steep slopes. Guardrail stacking devices are equipment used to automatically stack guardrails, mainly used by guardrail manufacturers or related logistics sites in traffic engineering.
[0003] However, existing technologies still have the following problems: In the traditional production process of guardrail panels, the stacking process is usually done manually. Manual stacking has many drawbacks, such as high labor intensity. Workers are prone to fatigue due to repeated handling and stacking of guardrail panels for long periods of time, which leads to low work efficiency. Moreover, it is difficult to guarantee the accuracy and consistency of manual stacking, which can easily result in problems such as uneven stacking and positional deviations. Furthermore, the guardrail panels need to be repeatedly grasped during the handling process, which can easily lead to them falling off due to insufficient grip, increasing the danger and damage rate of guardrail panel handling. Utility Model Content
[0004] To address the issues of low palletizing efficiency and difficulty in gripping guardrails, the purpose of this invention is to provide an automatic palletizing device for a guardrail production line.
[0005] To solve the above technical problems, this utility model adopts the following technical solution: an automatic palletizing device for a guardrail production line, comprising two gantry frames, with side beams fixedly connected to the upper surfaces of both gantry frames, and a crossbeam slidably connected to the upper surfaces of the two side beams. A first lead screw is rotatably connected inside the side beam, and the outer surface of the first lead screw is threadedly sleeved with the lower surface of the crossbeam. A first motor is fixedly installed at the end of the side beam, and the output top of the first motor is fixedly connected to the side beam. A movable plate is slidably connected to the upper surface of the crossbeam, and a support frame is fixedly installed on the upper surface of the movable plate. A third motor is fixedly connected to the upper end of the support frame, and a second lead screw is rotatably connected inside the support frame. The output end of the third motor is fixedly connected to the second lead screw, and a support cross plate is threadedly sleeved on the outer surface of the second lead screw. Clamping devices are symmetrically fixedly connected to the outer surface of the support cross plate.
[0006] Preferably, the clamping device includes a top plate, one side of which is fixedly connected to a supporting cross plate. Clamping plates are symmetrically slidably connected to the lower surface of the top plate. A first cylinder is fixedly installed on the lower surface of the top plate. The output end of the first cylinder is fixedly connected to one of the clamping plates. A second cylinder and a movable plate are rotatably connected to one side and lower end of one of the clamping plates, respectively. The output end of the second cylinder is rotatably connected to the movable plate. A plurality of L-shaped claws are fixedly installed on one side of the movable plate.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes a combination of side beams, crossbeams, support frames, and clamping devices. A first motor, a second motor, and a third motor drive the crossbeam to move laterally, the moving plate to move longitudinally, and the support plate to rise and fall vertically. Combined with a transmission structure including gears, toothed plates, and lead screws and nuts, the clamping device can be moved quickly and accurately to the target position, automating the entire process of guardrail grabbing, handling, and stacking. This significantly improves stacking efficiency. In the clamping device, a cylinder pushes the clamping plate for initial clamping, a second cylinder drives an L-shaped claw to further tighten the clamp from the side, and an anti-slip pad increases friction. These multiple safeguards ensure a firm and stable clamping of the guardrail, preventing slippage and collisions during handling. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Example: Figure 1-3 As shown, this utility model provides an automatic palletizing device for a guardrail production line, including two gantry frames 11. The two gantry frames 11 serve as the support base for the entire device, providing a stable installation platform for subsequent components. Side beams 12 are fixedly connected to the upper surfaces of both gantry frames 11. First slide rails 15 are symmetrically fixedly connected to the upper surfaces of the side beams 12. Two first sliders 16 are slidably sleeved on the upper surfaces of the first slide rails 15. The upper surfaces of the first sliders 16 are fixedly connected to the lower surface of a crossbeam 13, forming a guide structure for the lateral movement of the crossbeam 13. A first lead screw 14 is rotatably connected inside the side beam 12, and the outer surface of the first lead screw 14 is threadedly sleeved to the lower surface of the crossbeam 13. A first motor 17 is fixedly installed at the end of the side beam 12, and the output end of the first motor 17 is fixedly connected to the first lead screw 14. When the first motor 17 starts, it drives the first lead screw 14 to rotate. Utilizing the threaded transmission principle, the crossbeam 13, guided by the first sliders 16 and the first slide rails 15, moves laterally along the side beam 12, adjusting to the lateral position of the guardrail.
[0013] A second slide rail 18 is symmetrically fixedly connected to the upper surface of the crossbeam 13. Two second sliders 19 are slidably sleeved on the outer surface of the second slide rail 18. The upper surface of the second sliders 19 is fixedly connected to the moving plate 10, which serves as the guide structure for the longitudinal movement of the moving plate 10. A toothed plate 25 is fixedly installed on one side of the inner surface of the crossbeam 13. A second motor 24 is fixedly installed on the upper surface of the moving plate 10. The output end of the second motor 24 passes through the moving plate 10 and is fixedly sleeved with a gear 26. The outer surface of the gear 26 meshes with one side of the toothed plate 25. When the second motor 24 runs, it drives the gear 26 to rotate. Through the meshing transmission between the gear 26 and the toothed plate 25, the moving plate 10 moves longitudinally along the crossbeam 13 under the guidance of the second sliders 19 and the second slide rail 18, moving closer to the guardrail.
[0014] A support frame 20 is fixedly installed on the upper surface of the movable plate 10. A third motor 21 is fixedly connected to the upper end of the support frame 20. A second lead screw 22 is rotatably connected inside the support frame 20. The output end of the third motor 21 is fixedly connected to the second lead screw 22. A support cross plate 27 is threaded onto the outer surface of the second lead screw 22. Guide rods 23 are symmetrically fixedly connected to the outer surface of the support frame 20. Both guide rods 23 pass through the support cross plate 27 and slide against the inner wall of one side of the support cross plate 27. After the third motor 21 starts, it drives the second lead screw 22 to rotate. Under the threaded transmission, the support cross plate 27 moves vertically up and down along the guide rods 23, reaching the height of the guardrail. Clamping devices 28 are symmetrically fixedly connected to the outer surface of the support cross plate 27.
[0015] The clamping device 28 includes a top plate 29, one side of which is fixedly connected to a supporting horizontal plate 27. A third slide rail 30 is symmetrically fixedly installed on the lower surface of the top plate 29. The lower surface of the third slide rail 30 is slidably sleeved with a clamping plate 31. A first cylinder 32 is fixedly installed on the lower surface of the top plate 29. The output end of the first cylinder 32 is fixedly connected to one of the clamping plates 31. By extending and retracting the first cylinder 32, the clamping plate 31 can be pushed to slide on the third slide rail 30, initially achieving clamping of the guardrail. A second cylinder 33 and a movable plate 34 are rotatably connected to one side and lower end of one of the clamping plates 31, respectively. The output end of the second cylinder 33 is rotatably connected to the movable plate 34. Multiple L-shaped claws 35 are fixedly installed on one side of the movable plate 34. When the second cylinder 33 is working, it drives the movable plate 34 to rotate, causing the L-shaped claw 35 to move and further grab the guardrail from the side, enhancing the clamping stability. Anti-slip pads are fixedly installed on one side of both clamping plates 31 to increase the friction between them and the guardrail, preventing the guardrail from slipping during transportation. Through the coordinated movement of the above components, the grabbing, transportation and stacking operations of the guardrail are realized.
[0016] Working principle: Two gantry frames 11 serve as the supporting foundation for the entire device, with side beams 12 fixedly connected above them. A first lead screw 14 is rotatably connected inside the side beams 12, and a first motor 17 installed at the end of the side beams 12 is connected to the first lead screw 14. When the first motor 17 starts, it drives the first lead screw 14 to rotate. Since the first lead screw 14 is threadedly connected to the lower surface of the crossbeam 13, the crossbeam 13 slides on the upper surface of the side beams 12 under the threaded transmission action generated by the rotation of the lead screw. Simultaneously, the first slide rail 15 on the upper surface of the side beams 12 and the first slider 16 slidably connected to it provide guidance and stability, ensuring that the crossbeam 13 can move smoothly laterally along the side beams 12. A toothed plate 25 is fixed to one side of the inner surface of the crossbeam 13. A gear 26 is fixedly sleeved at the output end of the second motor 24 mounted on the movable plate 10 after passing through the movable plate 10, and the gear 26 meshes with the toothed plate 25. When the second motor 24 operates, it drives the gear 26 to rotate. The meshing action of the gear 26 and the toothed plate 25 causes the movable plate 10 to slide on the upper surface of the crossbeam 13. The second slide rail 18 on the upper surface of the crossbeam 13 and the second slider 19 slidably sleeved thereon provide stable guidance and support for the longitudinal movement of the movable plate 10, ensuring that the movable plate 10 can move longitudinally along the crossbeam 13. A support frame 20 is fixedly mounted on the movable plate 10. A third motor 21 at the upper end of the support frame 20 is connected to a second lead screw 22 internally. A support plate 27 is threaded onto the outer surface of the second lead screw 22. When the third motor 21 starts, it drives the second lead screw 22 to rotate, causing the support plate 27 to move vertically up and down along the guide rod 23 via threaded transmission. The guide rod 23 is symmetrically fixedly connected to the outer surface of the support frame 20, passes through the support plate 27, and slides against one inner wall. Its function is to ensure the stability and accuracy of the support plate 27 during vertical movement. A clamping device 28 is symmetrically and fixedly connected to the outer surface of the supporting horizontal plate 27. The top plate 29 of the clamping device 28 is fixedly connected to the supporting horizontal plate 27. The third slide rail 30 on the lower surface of the top plate 29 is slidably sleeved with the clamping plate 31, and the output end of the first cylinder 32 mounted on the lower surface of the top plate 29 is fixedly connected to one of the clamping plates 31. When the first cylinder 32 operates, it pushes the clamping plate 31 to slide on the third slide rail 30, achieving initial clamping of the guardrail. Simultaneously, a second cylinder 33 rotatably connected to one side of one of the clamping plates 31 drives the movable plate 34 to rotate. Multiple L-shaped claws 35 fixedly mounted on one side of the movable plate 34 then move accordingly, further strengthening the clamping effect on the guardrail and preventing it from falling off during the clamping process.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
