Description

Technical Field

[0001] This invention relates to the field of intelligent transportation technology, and more specifically, to an intelligent guardrail for road intersections and its manufacturing method. Background Technology

[0002] Intelligent transportation represents the future direction of transportation systems. It is a comprehensive transportation management system that effectively integrates advanced information technology, data communication and transmission technology, electronic sensing technology, control technology, and computer technology into the entire ground traffic management system, enabling it to function comprehensively and over a wide area. With urbanization, China's urban population is constantly increasing, leading to a surge in vehicles and pedestrian traffic. To better regulate traffic behavior, traffic barriers have been installed on many roads.

[0003] The high temperatures generated during the injection molding process of guardrails inside the mold are a significant concern. Current production methods for intelligent guardrails at road intersections involve waiting for the molten metal to cool down after molding before transferring them to a painting machine. This cooling process prolongs production time. Furthermore, existing methods cannot control the dripping of protective paint onto the guardrail based on its position in the painting machine, hindering the paint application process. Even after removing the guardrail from the painting machine, dripping paint continues, leading to waste and environmental pollution. Additionally, because painting and injection molding are separate processes, the high temperatures generated during injection molding prevent the drying of the paint. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A method for producing intelligent guardrails at road intersections, wherein the method is implemented by production equipment for intelligent guardrails at road intersections, and the production equipment for intelligent guardrails at road intersections includes: a fixing frame, a forming mold, and a painted plate.

[0011] The molding die includes a mold frame, a first translation template, a second translation template, and an upper translation template. The mold frame is fixedly connected to the side wall of the fixed frame. The first translation template and the second translation template are located on both sides of the mold frame, and the upper translation template is located directly above the mold frame. The mold frame, the first translation template, the second translation template, and the upper translation template fit together to form a mold cavity. An injection port is provided on the opposite side wall of the mold frame.

[0012] A rotating rod is rotatably connected to the side wall of the fixed frame. The ends of the first translation template and the second translation template are slidably connected to the rotating rod. A gear is fixedly connected to the rotating rod. A rack is fixedly connected to the side wall of the upward template. The gear meshes with the rack.

[0013] Both sides of the forming mold are provided with receiving boxes, which are fixedly connected to the fixing frame. The paint plate is fixedly connected to the side wall of the receiving box near the upper moving template, and a layer of brush bristles is fixedly connected to the side wall of the paint plate near the upper moving template.

[0014] Preferably, both ends of the rotating rod are fixedly connected to threaded rods, and the end of the threaded rod away from the rotating rod is rotatably connected to the side wall of the fixed frame. Both the first translation template and the second translation template are fixedly connected to connecting plates, and both ends of the connecting plates are threadedly connected to the threaded rods.

[0015] The end of the threaded rod is fixedly connected to a rotating shaft. The end of the rotating shaft is rotatably connected to the side wall of the fixed frame and passes through the side wall of the fixed frame. A servo motor is fixedly connected to the side wall of the fixed frame, and a redirecting shaft is rotatably connected to the fixed frame. Pulleys are fixedly connected to the redirecting shaft, the output shaft of the servo motor, and the rotating shaft. A belt is sleeved on the pulley, and multiple pulleys are driven by belts.

[0016] Preferably, the interior of the paint plate is hollow, and the end of the paint plate that contacts the receiving box is open. At least two through holes are provided on the side wall of the paint plate that connects to the brush bristles, and the through holes cooperate with the brush bristles.

[0017] Preferably, the open end of the painted plate is covered by a baffle, a push rod is fixedly connected to the side wall of the baffle, one end of the push rod passes through the side wall of the painted plate and is fixedly connected to a push block, a spring is fixedly connected to the push block, and the end of the spring away from the push block is fixedly connected to the painted plate.

[0018] Preferably, a horizontal plate is fixedly connected to the upper surface of the upward moving template, and the rack is fixedly connected to the side wall of the horizontal plate.

[0019] A limiting plate is fixedly connected to the side wall of the horizontal plate, and the limiting plate cooperates with the push block.

[0020] Preferably, the production method of the intelligent guardrail at the road intersection specifically includes the following steps:

[0021] S1: Molten metal is injected into the mold cavity through the injection port on the mold frame, and then cooled and solidified to form a protective barrier.

[0022] S2: Start the servo motor. The output shaft of the servo motor drives the rotating shaft, threaded rod, and rotating rod to rotate through the cooperation of the pulley and belt. This drives the first and second translational templates to move in opposite directions. During the rotation of the rotating rod, the meshing of the gear and rack drives the rack, horizontal plate, and upper moving template to move upward. At this time, the mold cavity is open, which facilitates the demolding of the cooled and formed guardrail.

[0023] S3: During the upward movement of the template, when the limiting plate comes into contact with the push block, the push block is pushed towards the paint plate by the pushing of the limiting plate. The baffle is separated from the opening end of the paint plate, and the protective paint in the container flows onto the brush bristles through the through holes on the paint plate. When the guardrail moves upward and comes into contact with the brush bristles, the protective paint on the brush bristles comes into contact with the guardrail and adheres to the guardrail, thus realizing the painting treatment of the guardrail.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In this invention, rainwater is collected by the upper horizontal bar and flows into the collection box through the vertical bar for collection, thus realizing the collection and utilization of rainwater and avoiding the waste of water resources. The data is transmitted to the controller through the meteorological sensor, and the controller controls the water pump to start. The water pump inputs the rainwater collected in the collection box into the lower horizontal bar, and then sprays it out through the water outlet to water and maintain the ground near the guardrail, thereby realizing the recycling of rainwater.

[0026] 2. In this invention, the output shaft of the servo motor drives the pulley and belt to rotate, which in turn drives the rotating shaft, threaded rod, and rotating rod to rotate. This drives the first and second translational templates to move in opposite directions. Simultaneously, through the meshing of gears and racks, the rack, horizontal plate, and upper template are driven to move upward, facilitating the demolding of the formed guardrail. The pusher block is pushed towards the painting plate by the limiting plate, allowing the protective paint in the receiving box to flow through the through-holes in the painting plate onto the brush bristles. The protective paint on the brush bristles contacts and adheres to the guardrail, achieving the painting process. Simultaneously, the residual heat on the guardrail dries the protective paint adhering to it, thus improving the drying speed of the protective paint coating on the guardrail surface. This not only facilitates the injection molding of the guardrail, avoiding welding between the upper, vertical, and lower horizontal bars, but also facilitates the painting process, saving manpower and time.

[0038] Example 1 further illustrates the intelligent guardrail for road intersections and its production method proposed in this invention.

[0039] A smart guardrail for road intersections includes: guardrail 1 and collection box 2.

[0040] The guardrail 1 includes an upper horizontal bar 3, a vertical bar 4, and a lower horizontal bar 5. The two ends of the vertical bar 4 are fixedly connected to the lower surface of the upper horizontal bar 3 and the upper surface of the lower horizontal bar 5, respectively. The interiors of the upper horizontal bar 3, the vertical bar 4, and the lower horizontal bar 5 are all hollow, and the top of the upper horizontal bar 3 is open. The lower horizontal bar 5 is fixedly connected to the collection box 2, and a water outlet 6 is provided on the side wall of the lower horizontal bar 5. The lower end of the vertical bar 4 passes through the lower horizontal bar 5 and is connected to the collection box 2.

[0041] A water pump 7 is fixedly connected to the bottom of the collection box 2. The water pump 7 is connected to the lower crossbar 5 through a pipe 8. A weather sensor is fixedly connected to the guardrail 1. The weather sensor is connected to the water pump 7 through a controller. When the weather is relatively dry, the weather sensor transmits data to the controller, and the controller controls the water pump 7 to turn on. The water pump 7 pumps the water in the collection box 2 into the cavity formed between the lower crossbar 5 and the top of the collection box 2, and then sprays it out through the water outlet 6 to water the ground near the guardrail 1. This not only prevents the ground from cracking, but also reduces the flying of dust. The controller is electrically connected to the traffic light at the road intersection. When the green light appears, the water pump 7 is turned off to prevent water from splashing onto pedestrians when they pass by the guardrail 1.

[0042] The lower end of the vertical rod 4 passes through the lower horizontal rod 5 and extends into the interior of the collection box 2. The upper horizontal rod 3 is connected to the collection box 2 through the vertical rod 4, and a horizontally arranged filter screen 9 is fixedly connected to the open end of the upper horizontal rod 3. The filter screen 9 can filter out particulate matter in the rainwater to prevent particulate matter from entering the collection box 2 and causing blockage of the water pump 7. The collection box 2 is connected to the water supply system through a pipe, so that the water in the collection box 2 can be easily filled when the water level in the collection box 2 is low.

[0043] Working principle: The collection box 2 is buried underground, and the lower crossbar 5 is fixed to the collection box 2 using existing technologies such as bolts. In rainy weather, the weather sensor transmits data to the controller, which controls the water pump 7 to shut off, preventing the water pump 7 from releasing water from the collection box 2 during rainy weather, thus avoiding water waste. The rainwater falling into the upper crossbar 3 flows into the collection box 2 through the vertical bar 4 and is collected, realizing the collection and utilization of rainwater and avoiding water waste. In sunny weather when the ground is relatively dry, the weather sensor transmits data to the controller, which controls the water pump 7 to turn on. The water pump 7 inputs the rainwater collected in the collection box 2 into the lower crossbar 5, and then sprays it out through the water outlet 6 to water and maintain the ground near the guardrail 1, preventing the ground from cracking, thus realizing the recycling of rainwater.

[0044] Example 2

[0045] The following technical features are added based on Embodiment 1:

[0046] A method for producing intelligent guardrails at road intersections is provided. The method for producing intelligent guardrails at road intersections is implemented through production equipment for intelligent guardrails at road intersections. The production equipment for intelligent guardrails at road intersections includes: a fixing frame 10, a forming mold 11, and a painted plate 12.

[0047] The molding die 11 includes a die frame 13, a first translation template 14, a second translation template 15, and an upper translation template 16. The die frame 13 is fixedly connected to the side wall of the fixing frame 10. The first translation template 14 and the second translation template 15 are located on both sides of the die frame 13, and the upper translation template 16 is located directly above the die frame 13. The die frame 13, the first translation template 14, the second translation template 15, and the upper translation template 16 fit together to form a die cavity 17. An injection port is provided on the opposite side wall of the die frame 13.

[0048] The mold frame 13 and the upper moving template 16 have strip-shaped protrusions on their opposite sidewalls. These protrusions facilitate the formation of the hollow portions inside the upper horizontal bar 3 and lower horizontal bar 5. The strip-shaped protrusions on the mold frame 13 have at least two rectangular holes. At least two fixing rods are fixedly connected to the strip-shaped protrusions on the upper moving template 16. The number of fixing rods and rectangular holes corresponds to the number of vertical bars 4 on the guardrail 1. During injection molding, the lower ends of the fixing rods contact the bottom of the rectangular holes, facilitating the formation of the portion of the vertical bar 4 inside the lower horizontal bar 5 in the guardrail 1. The first and second moving templates 14 have fixed... The first translation template 14 has a rectangular protrusion, and the thickness of the rectangular protrusion on the first translation template 14 is greater than the thickness of the rectangular protrusion on the second translation template 15. The rectangular protrusion on the first translation template 14 has at least two strip grooves. Through the cooperation of the fixing rod and the strip groove, it is easy to form the hollow vertical bar 4 in the guardrail 1 during injection molding. The second translation template 15 has multiple horizontal bars horizontally arranged on the lower side of the rectangular protrusion. The number of horizontal bars is consistent with the number of water outlet holes 6 on the guardrail 1. During injection molding, the horizontal bars contact the side wall of the strip protrusion on the lower horizontal bar 5, which facilitates the formation of the water outlet holes 6 on the lower horizontal bar 5.

[0049] A rotating rod 18 is rotatably connected to the side wall of the fixed frame 10. The ends of the first translation template 14 and the second translation template 15 are slidably connected to the rotating rod 18. A gear 19 is fixedly connected to the rotating rod 18. A rack 20 is fixedly connected to the side wall of the upper translation template 16. The gear 19 meshes with the rack 20. The rotating rod 18 is located on both sides of the forming mold 11, which facilitates driving the two ends of the first translation template 14 and the second translation template 15 to move simultaneously, preventing one end of the first translation template 14 and the second translation template 15 from shifting during the translation process.

[0050] Both sides of the molding die 11 are provided with receiving boxes 21, which are fixedly connected to the fixing frame 10. The paint plate 12 is fixedly connected to the side wall of the receiving box 21 near the upper moving template 16, and a layer of brush bristles 22 is fixedly connected to the side wall of the paint plate 12 near the upper moving template 16. The top of the receiving box 21 is provided with a feed port, which is covered with a cover plate to facilitate the injection of protective paint into the receiving box 21.

[0051] Both ends of the rotating rod 18 are fixedly connected to threaded rods 23. The end of the threaded rod 23 away from the rotating rod 18 is rotatably connected to the side wall of the fixed frame 10. Both the first translation template 14 and the second translation template 15 are fixedly connected to connecting plates 24. The two ends of the connecting plates 24 are threadedly connected to the threaded rods 23. The threads on the threaded rods 23 at both ends of the rotating rod 18 are arranged in opposite directions. When the rotating rod 18 drives the two threaded rods 23 to rotate, it is convenient for the two threaded rods 23 to simultaneously drive the first translation template 14 and the second translation template 15 to move towards each other or in the same direction.

[0052] A rotating shaft 25 is fixedly connected to the end of the threaded rod 23. The end of the rotating shaft 25 is rotatably connected to the side wall of the fixed frame 10 and passes through the side wall of the fixed frame 10. A servo motor 26 is fixedly connected to the side wall of the fixed frame 10, and a redirecting shaft 27 is rotatably connected to the fixed frame 10. Pulleys 28 are fixedly connected to the redirecting shaft 27, the output shaft of the servo motor 26, and the rotating shaft 25. A belt 29 is fitted on the pulley 28. Multiple pulleys 28 are driven by the belt 29. The belt 29 winds around the redirecting shaft 27. When the pulley 28 is in contact with the upper surface of the belt 29, the belt 29 drives the two rotating shafts 25 to rotate through the pulley 28. The two rotating shafts 25 rotate in opposite directions, and the two gears 19 rotate in opposite directions as well. This makes it easy for the two gears 19 to drive the upper moving template 16 to move up or down at the same time. In addition, the threads of the threaded rods 23 connected to the two ends of the connecting plate 24 are set in opposite directions, which makes it easy for the two threaded rods 23 to drive the connecting plate 24 to move horizontally at the same time.

[0053] The interior of the paint plate 12 is hollow, and the end of the paint plate 12 that contacts the receiving box 21 is open. At least two through holes 30 are provided on the side wall of the paint plate 12 that connects to the brush bristles 22. The through holes 30 cooperate with the brush bristles 22.

[0054] A baffle 31 covers the open end of the painted plate 12. A push rod 32 is fixedly connected to the side wall of the baffle 31. One end of the push rod 32 passes through the side wall of the painted plate 12 and is fixedly connected to a push block 33. A spring 34 is fixedly connected to the push block 33. The end of the spring 34 away from the push block 33 is fixedly connected to the painted plate 12.

[0055] A horizontal plate 35 is fixedly connected to the upper surface of the upward template 16, and a rack 20 is fixedly connected to the side wall of the horizontal plate 35.

[0056] A limiting plate 36 is fixedly connected to the side wall of the horizontal plate 35. The limiting plate 36 cooperates with the push block 33. The end of the push block 33 away from the push rod 32 is hemispherical, which makes it easy for the limiting plate 36 to push the push block 33 towards the paint plate 12. A horizontally set fixing plate is fixedly connected to the fixing frame 10. A vertical plate is fixedly connected to the fixing plate. The upper end of the vertical plate extends to the upper side of the push block 33. The limiting plate 36 is slidably connected to the vertical plate, which makes it easy for the limiting plate 36 to drive the upper moving template 16 to move up and down. The height of the limiting plate 36 is consistent with the height of the guardrail 1.

[0057] The production method of intelligent guardrails at road intersections specifically includes the following steps:

[0058] S1: Molten metal is injected into the mold cavity 17 through the injection port on the mold frame 13, and waits for it to cool and solidify to form the protective railing 1.

[0059] S2: Start the servo motor 26. The output shaft of the servo motor 26 drives the rotating shaft 25, the threaded rod 23, and the rotating rod 18 to rotate through the cooperation of the pulley 28 and the belt 29. This drives the first translation template 14 and the second translation template 15 to move in opposite directions. During the rotation of the rotating rod 18, the gear 19 meshes with the rack 20, driving the rack 20, the horizontal plate 35, and the upper moving template 16 to move upward. At this time, the mold cavity 17 is open, which facilitates the demolding of the cooled and formed guardrail 1.

[0060] S3: During the upward movement of the template 16, when the limiting plate 36 comes into contact with the push block 33, the push block 33 is pushed towards the paint plate 12 by the pushing of the limiting plate 36. The baffle 31 is separated from the opening end of the paint plate 12, and the protective paint in the container 21 flows through the through hole 30 on the paint plate 12 to the brush bristles 22. When the guardrail 1 moves upward and comes into contact with the brush bristles 22, the protective paint on the brush bristles 22 comes into contact with the guardrail 1 and adheres to the guardrail 1, thus realizing the painting treatment of the guardrail 1.

[0061] Working principle: Molten metal is injected into the mold cavity 17 through the injection port on the mold frame 13, and waits for it to cool and solidify to form the protective railing 1.

[0062] The servo motor 26 is started. The output shaft of the servo motor 26 drives the rotating shaft 25, the threaded rod 23, and the rotating rod 18 to rotate through the cooperation of the pulley 28 and the belt 29. This drives the first translation template 14 and the second translation template 15 to move in opposite directions. During the rotation of the rotating rod 18, the gear 19 meshes with the rack 20, driving the rack 20, the horizontal plate 35, and the upper moving template 16 to move upward. At this time, the mold cavity 17 is open. During the upward movement of the upper moving template 16, the formed guardrail 1 moves upward.

[0063] During the upward movement of the template 16, when the limiting plate 36 contacts the push block 33, the pushing of the limiting plate 36 pushes the push block 33 toward the painting plate 12. The baffle 31 disengages from the opening end of the painting plate 12, and the protective paint in the receiving box 21 flows through the through hole 30 on the painting plate 12 onto the brush bristles 22. When the guardrail 1 moves upward and contacts the brush bristles 22, the protective paint on the brush bristles 22 contacts and adheres to the guardrail 1, thus achieving the painting treatment of the guardrail 1. At the same time, the residual heat on the guardrail 1 dries the protective paint adhering to the guardrail 1, thereby improving the quality of the paint. The drying speed of the protective paint coated on the surface of the guardrail 1 is such that when the lower end of the guardrail 1 detaches from the brush bristles 22, the lower end of the limiting plate 36 also detaches from the push block 33. Due to the elastic force of the spring 34, the push block 33 is pushed away from the paint plate 12. At this time, the baffle 31 is attached to the end of the paint plate 12, preventing the protective paint in the receiving box 21 from continuing to flow into the interior of the paint plate 12, thereby preventing excessive protective paint adhering to the brush bristles 22 from dripping and avoiding waste of protective paint. After the protective paint on the guardrail 1 dries, the worker pulls the guardrail 1 down, causing the guardrail 1 to detach from the upper moving template 16.

[0064] After the guardrail 1 is demolded, the servo motor 26 is restarted. The servo motor 26 rotates in the opposite direction, driving the rotating shaft 25, threaded rod 23, and rotating rod 18 to rotate through the cooperation of belt 29 and pulley 28. This drives the first translation template 14 and the second translation template 15 to move towards each other. The rotating rod 18 drives the gear 19 to rotate, and through the meshing of gear 19 and rack 20, it drives the horizontal plate 35 and the upper moving template 16 to move downward. When the edges of the first translation template 14, the second translation template 15, and the upper moving template 16 are all in contact with the edges of the mold frame 13, the mold cavity 17 is in a closed state, which facilitates the injection of molten metal into the mold cavity 17, thereby facilitating the formation of the guardrail 1.
