Description

Technical Field

[0001] This invention relates to the field of guardrail manufacturing technology, and in particular to a production system and process for vertically cast guardrails. Background Technology

[0002] The main function of crash barriers is to prevent out-of-control vehicles from running off the road, reducing casualties and property damage in traffic accidents. Installing crash barriers on dangerous road sections such as highways, bridges, sharp bends, and steep slopes can effectively reduce the frequency and severity of accidents, providing additional safety for drivers and passengers.

[0003] However, traditional methods of railing manufacturing often involve horizontal casting or manual assembly, which are not only inefficient but also make it difficult to guarantee product quality. For example, in mold cleaning and drying, traditional methods often rely on manual labor, which is not only inefficient but also prone to damaging the molds and affecting subsequent casting results.

[0004] Therefore, it is necessary to propose a new production system and process for guardrail manufacturing. This system realizes a fully automated production process, ensuring the accuracy and stability of each production step, thereby improving the quality and production efficiency of the guardrail.

Detailed Implementation

[0037] The technical solution of the present invention will now be described with reference to the accompanying drawings. However, the described embodiments are only some embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 6As shown, the present invention provides a production system for vertically cast guardrails, including a track device 10, and a curing kiln 20, a mold taking device 30, a cleaning device 40, a drying chamber 50, a steel bar assembly device 60, a mold closing device 70, and a feeding device 80 connected in sequence through the track device 10. A mold carriage 11 is arranged on the track device 10, wherein the mold carriage 11 includes a vertical casting mold 111 and a moving device 112 arranged at the bottom of the vertical casting mold 111. The mold carriage 11 moves on the track device 10 through the moving device 112.

[0039] Specifically, the track system is made of high-strength steel and runs throughout the entire production line system, providing a stable path for the mold carts. The track system includes straight sections, curves, and intersections to accommodate the layout requirements between different processes. Positioning points and sensors are also installed on the track to ensure accurate stopping of the mold carts at each process stage.

[0040] The mold carriage is a mobile platform that carries the vertical casting mold. It consists of a robust frame with wheels or rollers at the bottom that match the track system, and a drive system (such as an electric motor or hydraulic motor) to provide power. The vertical casting mold is mounted on the frame by bolts, clips, or other fixing methods.

[0041] like Figure 2 As shown, in this embodiment, the vertical casting mold 111 includes an inner support base 1111, and a molding plate assembly 1112 that can rotate relative to the inner support base 1111 is attached to the inner support base 1111. The molding plate assembly 1112 and the inner support base 1111 cooperate to form at least one molding cavity 1113.

[0042] Specifically, the vertical casting mold is made of high-strength alloy steel or cast iron, possessing excellent wear resistance and corrosion resistance. The mold contains an internal support base and molding plate assemblies; these components are precision-machined and assembled to ensure the dimensional accuracy and surface quality of the finished guardrail. The molding plate assemblies can be designed in different shapes and sizes to meet the design requirements of various guardrails.

[0043] like Figures 3 to 5 As shown, in this embodiment, the mold-taking device 30 includes a clamping fixture 31 and a mold-opening fixture 32. The clamping fixture 31 includes a movable frame 311 and a support base 312 slidably connected to the movable frame 311. A slide rail device 313 is provided between the movable frame 311 and the support base 312. The movable frame 311 includes a movable frame 314. A movable frame 315 is passed through the movable frame 314. A clamping device 316 is provided on the movable frame 315. A lifting device 317 and a positioning device 318 are provided between the clamping device 316 and the movable frame 314.

[0044] The mold opening fixture 32 includes a mold opening frame 321 embedded in the support base 312 and a mold opening slide 322 slidably connected to the mold opening frame 321. The mold opening slide 322 has a mold opening end 323, and a mold opening device 324 for opening the vertical casting mold 111 is provided at the mold opening end 323.

[0045] Specifically, the clamping fixture is used to safely remove the mold from the mold carrier after it has cooled and solidified. The movable frame is a robust framework structure used to support and move the entire clamping fixture, including one or more moving axes to achieve horizontal, vertical, or tilting movement. The support base is the mounting platform for the clamping device, which, through a sliding connection with the movable frame, allows for precise positioning of the clamping device above the mold. A slide rail system provides a smooth and precise sliding path for the support base, ensuring the clamping device can move accurately above the mold. The movable frame slides within the movable frame to adjust the height and angle of the clamping device to accommodate the clamping requirements of different molds. The clamping device is the core component of the clamping fixture; it is typically hydraulically or pneumatically driven and can firmly clamp the mold and prevent it from slipping. A lifting device is used to adjust the height of the clamping device to accommodate the clamping requirements of different molds. A positioning device ensures precise positional control of the clamping device during movement.

[0046] Furthermore, the mold-opening fixture is used to open the mold and remove the finished guardrail after the mold has cooled and solidified. The mold-opening fixture includes a mold-opening frame and a mold-opening slide. The mold-opening frame is the main supporting structure of the mold-opening fixture; it is embedded in the support base and slidably connected to the mold-opening slide. The mold-opening slide slides on the mold-opening frame, and its opening end is equipped with a special mold-opening device (such as a hydraulic cylinder, pneumatic cylinder, or mechanical lever) to realize the mold opening action.

[0047] like Figure 2 As shown, in this embodiment, the molding plate assembly 1112 includes molding side plates 1114 respectively hinged to both sides of the inner support base 1111, and molding edge plates 1115 respectively hinged to both ends of the inner support base 1111. A locking device 113 and an unlocking protrusion 1131 are provided on the molding side plate 1114.

[0048] Specifically, the molding plate assembly is a crucial component of the vertical casting mold, determining the shape and size of the finished guardrail. The molding plate assembly consists of molding side plates and molding edge plates, which are hinged to the sides and ends of the inner support base, respectively. This hinged design allows the molding plate assembly to rotate to a certain extent relative to the inner support base, thus adapting to the production needs of guardrails with different shapes. The molding side plates are also equipped with locking devices and unlocking protrusions to fix the position of the molding plate assembly when the mold is closed, and to facilitate unlocking and separation of the molding plate assembly when the mold is opened.

[0049] The locking device 113 includes a positioning bolt 1132 protruding from the molded side plate 1114, a locking arm 1133 sleeved on the positioning bolt 1132, and a locking protrusion 1134 protruding from the molded side plate 1115. The locking arm 1133 is also provided with an unlocking ramp 1135.

[0050] Specifically, the locking device is a key component ensuring the stability and accuracy of the mold during mold closing. A positioning bolt protrudes from the mold side plate, serving as support and positioning points for the locking arm. The locking arm is fitted onto the positioning bolt and can rotate to a certain extent around it. A locking protrusion protrudes from the mold side plate, cooperating with the locking arm to form a locking structure. When the mold closes, the locking arm rotates and engages with the locking protrusion, locking the mold. An unlocking ramp is also provided on the locking arm for easy unlocking during mold opening.

[0051] like Figure 2 As shown, in this embodiment, the mold opening device 324 includes a lever 325 for levering the molded side plate 1114 and an unlocking member 326 for prying up the unlocking ramp 1135.

[0052] The mold opening device is a key component in the mold opening process. The mold opening device includes an unlocking component that can pry up the unlocking ramp on the locking arm, thereby disengaging the locking arm from the locking protrusion and realizing the unlocking and opening of the mold.

[0053] like Figure 3 and Figure 4 As shown, in this embodiment, the movable frame 315 includes two vertical rods 3151 arranged in the vertical direction. An upper connecting rod 3152 and a lower connecting rod 3153 are arranged in parallel between the two vertical rods 3151. The clamping device 316 includes two clamping posts 3154 extending downward from both ends of the lower connecting rod 3153, a first clamping part 3155 that is respectively hinged to the clamping posts 3154 and can rotate relative to each other, and a second clamping part 3156 that is rotatably connected to the first clamping part 3155. The lower connecting rod 3153 is also provided with an unlocking push rod 3157 corresponding to the unlocking protrusion 1131.

[0054] Specifically, the clamping device is a key component in the mold-opening process. The movable frame provides stable support and mobility for the clamping device. The clamping device consists of clamping posts extending downwards from both ends of the lower connecting rod, a first clamping part, and a second clamping part. The first clamping part is hinged to the clamping posts and can rotate relative to them. The second clamping part is rotatably connected to the first clamping part, allowing for further adjustment of the clamping angle and force. An unlocking push rod corresponding to the unlocking protrusion is also provided on the lower connecting rod, used to push the unlocking protrusion during mold opening to unlock and separate the mold.

[0055] like Figures 3 to 5As shown, in this embodiment, the molding device 30 further includes a drop protection device 33, which includes a side plate receiving column 331 for receiving the molding side plate 1115 and a side plate receiving arm 332 for receiving the molding side plate 1114.

[0056] Specifically, the anti-fall device is a safety component during the mold removal process. The anti-fall device includes side plate support pillars and side plate support arms, used to support the molding side plates and molding side plates respectively. During mold unlocking and separation, the anti-fall device prevents the mold from falling or being damaged due to loss of support, ensuring the safety and stability of the production line.

[0057] In this embodiment, the curing kiln includes a temperature control system and a humidity control system to accelerate the hardening process of cement concrete.

[0058] The curing kiln provides a stable and suitable hardening environment for the cement concrete in the mold through temperature and humidity control systems. The temperature control system adjusts the temperature inside the curing kiln to meet the temperature requirements of different cement concrete processes during hardening. The humidity control system controls the humidity inside the curing kiln to prevent the cement concrete from cracking or lacking strength due to excessively rapid drying.

[0059] like Figure 6 As shown, in this embodiment, the cleaning device 40 includes a cleaning mobile frame 41 and a cleaning base 42 slidably connected to the cleaning mobile frame 41. A movable cleaning frame 43 capable of lifting and lowering is slidably connected to the cleaning mobile frame 41, and a cleaning roller 44 is provided at the lower end of the movable cleaning frame 43.

[0060] Specifically, the cleaning device is a cleaning equipment on the production line. The cleaning device includes components such as a cleaning moving frame, a cleaning base, and a movable cleaning frame. The cleaning moving frame provides the mobility of the entire cleaning device. The cleaning base is slidably connected to the cleaning moving frame, allowing adjustment of the cleaning device's position and angle. The movable cleaning frame is slidably connected to the cleaning moving frame and can move up and down to adapt to molds of different heights and production line layouts. Cleaning rollers are installed at the lower end of the movable cleaning frame to roll on the mold surface and remove impurities and residues.

[0061] In this embodiment, the drying chamber is equipped with a heating system and a temperature control system for drying the vertical casting mold 111 and the mold car, and an oil spraying device is provided in the drying chamber.

[0062] Specifically, the drying chamber is the drying equipment on the production line. Equipped with a heating system and a temperature control system, the drying chamber provides a stable and suitable drying environment for molds and mold carriages. The heating system generates heat and heats the air inside the drying chamber to meet the drying requirements under different material and process conditions. The temperature control system regulates the temperature inside the drying chamber, preventing overheating or undercooling from damaging the molds and mold carriages. Furthermore, the drying chamber is equipped with an oil spraying device to spray an appropriate amount of lubricating oil or rust-preventive oil during the drying process to protect the surface quality of the molds and mold carriages and extend their service life.

[0063] In this embodiment, the rebar assembly device is used to precisely assemble the rebar cage in the mold. The arrangement and quantity of the rebar cage are typically determined based on the design requirements and load-bearing capacity of the guardrail. The mold closing device is used to lock and merge the molded plate assemblies of the vertical casting mold and prepare for concrete pouring. During the mold closing process, it is necessary to ensure that the molded plate assemblies of the vertical casting mold are fully aligned and in close contact to prevent concrete leakage or defects. The feeding device is used to transport raw materials such as concrete into the mold. During the feeding process, it is necessary to control the conveying speed and quantity of concrete to ensure that the mold is filled evenly and fully.

[0064] This invention also provides a manufacturing process for vertically cast guardrails, which uses the aforementioned production system for vertically cast guardrails and includes the following steps:

[0065] Step 1: The mold car 11 in the curing kiln 20 and the hardened guardrail in the mold car 11 are transported to the mold removal device 30 via the track device 10, and the hardened guardrail is removed from the mold car 11 by the mold removal device 30.

[0066] Step 2: The mold trolley 11 is transported from the mold taking device 30 to the cleaning device 40 via the track device 10, and the vertical casting mold 111 is cleaned by the cleaning device 40.

[0067] Step 3: The mold trolley 11 is transported from the cleaning device 40 to the drying chamber 50 via the track device 10, and the vertical casting mold 111 and the mold trolley 11 are dried in the drying chamber 50.

[0068] Step 4: Transport the mold trolley 11 from the drying chamber 50 to the rebar assembly device 60 via the track device 10, and place the rebar into the vertical casting mold 111 via the rebar assembly device 60.

[0069] Step 5: Transport the mold trolley 11 from the rebar assembly device 60 to the mold closing device 70 via the track device 10, and close the vertical casting mold 111 via the mold closing device 70;

[0070] Step 6: Transport the mold trolley 11 from the mold closing device 70 to the feeding device 80 via the track device 10, and then transport the cement concrete to the vertical casting mold 111 via the feeding device 80.

[0071] Step 7: The mold car 11 is transported from the feeding device 80 to the curing kiln 20 via the track device 10. The curing kiln 20 provides appropriate temperature and humidity conditions to accelerate the hardening process of the cement concrete.

[0072] In step three, the drying chamber 50 is used to dry the vertical casting mold 111 and the mold car 11 before spraying oil.
