Description

[0002] In the field of highway safety facilities, guardrails play a vital role in reducing vehicle collision damage and protecting drivers and passengers. Traditionally, guardrail installation relies primarily on on-site casting, a method that is not only inefficient but also difficult to ensure consistent construction quality. To improve construction efficiency and ensure the consistency and reliability of guardrails, prefabricated guardrail technology has emerged. Prefabricated guardrails are formed on a factory production line and then transported to the construction site for installation, improving construction efficiency.

DETAILED DESCRIPTION

[0039] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0040] See Figures 1 to 3 The processing equipment 1 for prefabricated guardrails in one embodiment of the present application can at least improve the convenience of demoulding and improve the safety of the demoulding process. Specifically, the processing equipment 1 for prefabricated guardrails includes a frame 10, a mold mechanism 20, a conveying mechanism 30 and a support mechanism 40. The mold mechanism 20 includes two side template assemblies 210 and two splint assemblies 220. Each side template assembly 210 can be movably set on the frame 10, and the two side template assemblies 210 are relatively spaced apart. Each splint assembly 220 can be movably set on the frame 10, and the two splint assemblies 220 are relatively spaced apart. The conveying mechanism 30 is set at the bottom of the mold mechanism 20, and the conveying direction of the conveying mechanism 30 is the direction from one side template assembly 210 to the other side template assembly 210. The support mechanism 40 is arranged on the conveying mechanism 30, and the conveying mechanism 30 is used to convey the support mechanism 40 to the bottom of the mold mechanism 20; in the mold closing state, the two side formwork assemblies 210 and the two clamping plate assemblies 220 move relative to the frame 10 to the support mechanism 40, and can form a casting space together with the support mechanism 40; when demolding, each side formwork assembly 210 can be flipped upward relative to the support mechanism 40, and each clamping plate assembly 220 can be flipped upward relative to the support mechanism 40.

[0041] During the processing of the prefabricated guardrail 2, the conveying mechanism 30 transports the support mechanism 40 to the bottom of the mold mechanism 20. The two side formwork assemblies 210 and two clamping plate assemblies 220 are controlled to surround the support mechanism 40 to form a casting space. Concrete is then poured into the casting space until the concrete reaches a predetermined height. When the concrete reaches a predetermined setting strength, the two side formwork assemblies 210 and two clamping plate assemblies 220 are controlled to flip upward. Finally, the conveying mechanism 30 is controlled to transport the support mechanism 40 to the unloading station for the prefabricated guardrail 2. During demolding, the mold mechanism 20 and the formed prefabricated guardrail 2 do not need to be flipped. Consequently, there is no need for large, heavy-duty flipping equipment, and there is no risk of the prefabricated guardrail 2 slipping during the flipping process. During demolding, only the two side formwork assemblies 210 and clamping plate assemblies 220 need to be controlled to flip upward, making the demolding process simple and convenient. There is no risk of the prefabricated guardrail 2 falling out of the mold mechanism 20 during demolding, thus improving demolding safety.

[0042] See Figure 2 and Figure 3 In one embodiment, the support mechanism 40 includes a support base form 410 and a separator 420. The support base form 410 is disposed on the conveying mechanism 30. The separator 420 is disposed on the support base form 410. The support base form 410, together with the two side formwork assemblies 210 and the two clamping plate assemblies 220, encloses a casting space. The separator 420 is located within the casting space and is capable of dividing the casting space into two casting chambers. The two side formwork assemblies 210 are symmetrically arranged with respect to the separator 420. The support base form 410 facilitates supporting the weight of the concrete forming the precast guardrail. The separator 420 facilitates simultaneous casting of two precast guardrails 2. The two precast guardrails 2 are arranged in opposite directions, improving the efficiency of the precast guardrail 2 molding process. Due to the separator 420, the two side formwork assemblies 210 can be configured with the same structure, reducing the structural complexity of the mold mechanism 20. In this embodiment, the separator 420 is fixed to the support base form 410 and, for example, can be integrally formed with the support base form 410. In other embodiments, the separator 420 may also be clamped on the supporting bottom mold 410 by a clamping structure or the like.

[0043] See also Figure 7 In one embodiment, the support mechanism 40 further includes a latching assembly 430, which is disposed on top of the divider 420. The latching assembly 430 is movable relative to the divider 420 and latched on the side of the prefabricated guardrail 2 facing away from the divider 420. After the prefabricated guardrail 2 is formed and demolded, the side of the prefabricated guardrail 2 facing away from the divider 420 is completely exposed. The conveying mechanism 30 needs to convey the support mechanism 40 with the prefabricated guardrail 2 to the unloading station. Therefore, by providing the latching assembly 430 to latch the side of the prefabricated guardrail 2 facing away from the divider 420, the possibility of the prefabricated guardrail 2 tipping over during conveyance is reduced, thereby ensuring stability and safety during conveyance.

[0044] Specifically, the latch assembly 430 includes a latching member 431 and a rotational drive member 432. The latching member 431 includes a connecting portion 433 and a latching portion 434 disposed on the connecting portion 433. The end of the connecting portion 433 away from the latching portion 434 is connected to the rotational drive member 432. The rotational drive member 432 is disposed on the partition 420 and is used to drive the latching member 431 to rotate so that the latching portion 434 can rotate to the side of the prefabricated guardrail 2 facing away from the partition 420. The latching portion 434 restricts the prefabricated guardrail 2 to the partition 420, reducing the possibility of the prefabricated guardrail 2 moving.

[0045] In this embodiment, there are two clamping members 431 , and the rotating driving member 432 can drive the two clamping members 431 to rotate toward the two casting cavities respectively, and can be respectively clamped on the prefabricated guardrails 2 located on both sides of the partition 420 .

[0046] In this embodiment, the cross-section of the casting cavity is largest when located on the support base mold 410. Specifically, the end of the prefabricated guardrail 2 with the larger cross-section is located at the bottom, while the end with the smaller cross-section is located at the top. This allows the prefabricated guardrail 2 to be more stably positioned on the support base mold 410 after demolding, reducing the possibility of the prefabricated guardrail 2 tipping over after demolding.

[0047] See Figure 1 、 Figure 4 and Figure 5 In one embodiment, the processing equipment 1 further includes an oil spraying mechanism 50, which is disposed on the conveying mechanism 30. The conveying mechanism 30 is used to transport the oil spraying mechanism 50 to the bottom of the mold mechanism 20. The two side formwork assemblies 210 and the two clamping plate assemblies 220 can be movable relative to the frame 10 to surround the oil spraying mechanism 50. The oil spraying mechanism 50 is used to spray mold release oil onto the inner walls of the side formwork assemblies 210 and the inner walls of the clamping plate assemblies 220. By providing the oil spraying mechanism 50, mold release oil can be sprayed onto the side formwork assemblies 210 and the clamping plate assemblies 220. This facilitates subsequent demolding by driving the side formwork assemblies 210 and the clamping plate assemblies 220 to flip after the prefabricated guardrail 2 is formed, thereby improving the convenience of demolding. After the conveying mechanism 30 transports the formed prefabricated guardrail 2 away from the mold mechanism 20, the conveying mechanism 30 transports the oil spraying mechanism 50 to the mold mechanism 20, effectively improving the efficiency of the processing and molding of the prefabricated guardrail 2.

[0048] Specifically, the oil spraying mechanism 50 includes an oil spraying body 510, a nozzle 520, a rotating driving member 530, an oil pump 540 and an oil storage tank 550. The oil spraying body 510 is arranged on the conveying mechanism 30, and the nozzle 520 is rotatably arranged on the oil spraying body 510. The rotating driving member 530 is used to drive the nozzle 520 to rotate on the oil spraying body 510. An oil spraying channel is formed in the nozzle 520. The oil pump 540 and the oil storage tank 550 are both arranged on the oil spraying body 510. The oil pump 540 connects the oil spraying channel with the space inside the oil storage tank 550. The oil pump 540 is used to pump the demoulding oil in the oil storage tank 550 to the oil spraying channel. The oil pump 540 can spray the demoulding oil stored in the oil tank 550 onto the side template assembly 210 and the splint assembly 220 through the nozzle 520, and the rotating drive member 530 can synchronously drive the nozzle 520 to rotate so that the demoulding oil sprayed out by the nozzle 520 can be more evenly adhered to the side template assembly 210 and the splint assembly 220.

[0049] In the embodiment, the spray head 520 includes a spray portion 521 and a rotating body 522 disposed on the spray portion. The rotating body 522 is hollow and has an oil inlet pipe 560 extending therethrough. The oil inlet pipe 560 has an oil injection channel formed therein. The rotating body 522 is rotatably mounted on the oil spray body 510. A spray chamber 523 is formed within the spray portion 521 and communicates with the interior space of the rotating body 522. A spray hole 524 is formed on the outer wall of the spray portion 521 and communicates with the spray chamber 523. The rotary drive member 530 can drive the rotating body 522 via a transmission member to cause the spray portion 521 to rotate relative to the oil inlet pipe 560 and the oil spray body 510. The oil inlet pipe 560 is connected to the oil storage tank 550 via an oil pump 540. The oil pump 540 pumps the demolding oil into the oil inlet pipe 560 and then into the spray chamber 523.

[0050] In one embodiment, the oil spray mechanism 50 further includes a filter 570. An oil receiving groove 512 is formed on the upper surface of the oil spray body 510. A filter hole 514 is defined on the bottom wall of the oil receiving groove 512. The filter 570 is disposed within the filter hole 514, and the filter hole 514 communicates with the interior of the oil storage tank 550. The oil receiving groove 512 allows for the recovery of mold release oil dripping from the side mold assembly 210 and the clamping plate assembly 220. The recovered mold release oil is filtered by the filter 570 and then recycled, thus avoiding waste of the mold release oil.

[0051] Specifically, the oil receiving groove 512 is an annular groove surrounding the nozzle 520. The bottom wall of the annular groove first decreases and then increases in height as it faces outward from the nozzle 520. A filter hole 514 is provided on the bottom wall at the lowest point of the annular groove. The provision of the oil receiving groove 512 allows the release oil in the oil receiving groove 512 to flow efficiently to the filter hole 514, improving recovery efficiency.

[0052] See Figure 2 、 Figure 3 and Figures 6 to 8 In one embodiment, the template mechanism further includes a first drive assembly 230 and a second drive assembly 240. The direction in which one side template assembly 210 moves away from the other side template assembly 210 is the demolding direction a, and the direction in which one side template assembly 210 moves toward the other side template assembly 210 is the clamping direction b. The first drive assembly 230 is disposed on the frame 10. The first drive assembly 230 is used to drive the two side template assemblies 210 to move the demolding distance along the demolding direction a, and then drive the side template assemblies 210 to rotate in a direction away from each other. The second drive assembly 240 is disposed on the frame 10. The second drive assembly 240 is used to drive the splint assembly 220 to flip upward or downward. Figure 2 and Figure 4 As shown, for the left side template assembly 210, the demoulding direction a is to the left, and the mold closing direction b is to the right; for the right side template assembly 210, the demoulding direction a is to the right, and the mold closing direction b is to the left.

[0053] After the precast guardrail 2 to be cast solidifies, the first drive assembly 230 drives the side formwork assembly 210 to move the demoulding distance along the demoulding direction a, and then continues to drive the side formwork assembly 210 to rotate in a direction away from each other. Since the side formwork assembly 210 is provided with an avoidance hole for the reserved steel bars of the precast guardrail 2, or a positioning column structure for forming the reserved hole of the precast guardrail 2, the first drive assembly 230 drives the side formwork assembly 210 to move the demoulding distance along the demoulding direction a first, so that the reserved steel bars exit the avoidance hole or the positioning column exits the reserved hole of the precast guardrail 22, and then continues to rotate the side formwork assembly 210 to achieve complete demoulding of the side formwork assembly 210. During the demoulding process, the driving side formwork assembly 210 moves outward first, which can avoid direct rotation, which may cause the reserved steel bars to be unable to pass through the avoidance hole or the positioning column to damage the hole wall of the reserved hole during rotation. By moving the driving side formwork assembly 210 outward first and then rotating, the convenience of demoulding is improved, and the integrity of the prefabricated guardrail 22 is ensured.

[0054] See Figure 3 、 Figures 6 to 8 In one embodiment, the side formwork assembly 210 includes a formwork body 211, a connector 212, a rotation axis 213, and a stopper 214. The connector 212 is connected to one end of the formwork body 211. The rotation axis 213 and the stopper 214 are both located on the side of the connector 212 away from the formwork body 211. The direction of the stopper 214 toward the rotation axis 213 is the demolding direction a, and the axis of the rotation axis 213 intersects the demolding direction a. The frame 10 is formed with a rotation groove 110, a connecting groove 120, and a stopper 130. The rotation groove 110 communicates with the stopper 130 through the connecting groove 120. The direction of the stopper 130 toward the rotation groove 110 is the demolding direction a. The connecting groove 120 extends through the side of the frame 10 facing the formwork body 211 to form a rotation opening 122. In the closed mold casting state, the stopper 214 is located within the stopper 130, and the rotation axis 213 is at least partially or entirely located within the rotation groove 110. In the demolding state, the first driving component 230 is used to drive the template body 211 to move along the demolding direction a, the rotating shaft 213 moves along the demolding direction a into the rotating groove 110, the limiting member 214 moves into the connecting groove 120 and is aligned with the rotating mouth 122, and the first driving component 230 drives the template body 211 to continue to move so that the rotating shaft 213 rotates in the rotating groove 110 and drives the template body 211 to rotate in the direction away from the other side template component 210 and drives the limiting member 214 to rotate toward the rotating mouth 122.

[0055] By setting the positional relationship between the rotating shaft 213 and the limiting member 214, and in relation to the rotating groove 110 and the limiting groove 130 on the frame 10, when the first drive assembly 230 drives the template body 211 to move, the limiting member 214 is located within the limiting groove 130, thereby restricting the template body 211 to movement. At this time, by controlling the movement distance of the limiting member 214 to the rotating opening 122, the demolding distance of the template body 211 can be controlled. When the limiting member 214 moves into the connecting groove 120, the restrictive effect of the limiting groove 130 and the limiting member 214 is eliminated, and the rotating shaft 213 can rotate within the rotating groove 110 again. At this time, the first drive assembly 230 can drive the template body 211 to rotate relative to the frame 10 via the rotating shaft 213. At this time, the limiting member 214 can rotate out of the rotating opening 122 around the axis of the rotating shaft 213 without interfering with the rotation of the rotating shaft 213. By virtue of the different positions of the rotating shaft 213 and the limiting member 214 at different times, the template body 211 is effectively moved first and then rotated.

[0056] Specifically, in the demolding state, the first drive assembly 230 is used to drive the template body 211 to move along the demolding direction a. The rotating shaft 213 moves into the rotating groove 110 and abuts against the inner wall of the rotating groove 110 facing the limiting groove 130. At this time, the limiting member 214 moves into the connecting groove 120 and aligns with the rotating opening 122. By the rotating shaft 230 abutting against the inner wall of the rotating groove 110, the stability and reliability of the rotation of the rotating shaft 213 can be improved, thereby improving the stability of the rotation of the template body 211.

[0057] See also Figure 9In this embodiment, the first drive assembly 230 includes a drive unit 231, a first moving member 232 and a first linkage member 233, a second moving member 234 and a second linkage member 235. One end of the first linkage member 233 is rotatably connected to one template body 211, and the other end is rotatably connected to the first moving member 232. One end of the second linkage member 235 is rotatably connected to the other template body 211, and the other end is rotatably connected to the second moving member 234. The drive unit 231 is used to drive the first moving member 232 and the second moving member 234 to move along the demolding direction a or the clamping direction b. When the first moving member 232 is driven to move by the drive unit 231, when the limiting member 214 is located in the limiting groove 130, the first moving member 232 drives the template body 211 to move along the demolding direction a through the first linkage member 233. When the limiting member 214 moves into the connecting groove 120, the limiting effect of the limiting member 214 is released. At this time, the first moving member 232 continues to move, and can drive the template body 211 to rotate around the axis of the rotating shaft 213 through the first linkage member 233. Then, the driving unit 231 only needs to drive the first moving member 232 to move, so that the template body 211 can be moved first and then rotated when demolding. There is no need to switch the driving mode of the driving unit 231 according to the active position of the template body 211. Similarly, the driving unit 231 drives the second moving member 234 and the second linkage member 235 in the same way to drive the other template body 211 to move.

[0058] Specifically, the drive unit 231 is used to drive the first movable member 232 and the second movable member 234 to move synchronously in opposite directions or toward each other. By having the drive unit 231 synchronously drive the first movable member 232 and the second movable member 234 to operate synchronously, the demolding and clamping efficiency of the two mold plates 211 can be improved. In other embodiments, two drive units 231 can also be provided, and the two drive units 231 respectively drive the first movable member 232 and the second movable member 234 to move.

[0059] See Figure 3 、 Figure 6 and Figure 9 In one embodiment, the driving unit 231 includes a driving power source 2311, a transmission gear set, a first moving rack 2312, and a second moving rack 2313. The first moving rack 2312 is connected to the first moving member 232, and the second moving rack 2313 is connected to the second moving member 234. Both the first moving rack 2312 and the second moving rack 2313 are meshed with the transmission gear set. The driving power source 2311 is used to drive the transmission gear set to rotate, thereby driving the first moving rack 2312 and the second moving rack 2313 to move synchronously in opposite directions or toward each other. The transmission gear set enables the first moving rack 2312 and the second moving rack 2313 to move synchronously in opposite directions or toward each other, thereby achieving synchronous opposite-direction or opposite-direction movement of the first moving member 232 and the second moving member 234.

[0060] In this embodiment, there are two first movable racks 2312 and two second movable racks 2313. The two first movable racks 2312 are spaced apart, and the two second movable racks 2313 are respectively located outside the two first movable racks 2312 and spaced apart from the first movable racks 2312. The transmission gear set includes a driving gear 2314, a first gear 2315, and two second gears 2316. The driving gear 2314 is meshed with the first gear 2315 and is located between the two middle first movable racks 2312. Each second movable rack 2313 is meshed with an adjacent first movable rack 2312 via a second gear 2316. The driving power source 2311 is used to drive the driving gear 2314 to rotate forward or reverse. The two first movable racks 2312 are both connected to the first movable member 232, and the two second movable racks 2313 are both connected to the second movable member 234. By providing two first movable racks 2312 to synchronously drive the movement of one template body 211, the reliability of driving the template body 211 can be improved. Similarly, by providing two second movable racks 2313 to synchronously drive the movement of the other template body 211, the reliability of driving the template body 211 can be improved. The movement direction of each first movable rack 2312 and second movable rack 2313 is determined by the driving gear 2314, the first gear 2315 and the two second gears 2316, so that synchronous movement toward or away from each other is achieved. During use, it is only necessary to control the driving power source 2311 to drive the driving gear 2314 to rotate forward or reverse.

[0061] In one embodiment, the number of the first moving members 232 and the first linkage members 233 is at least two, each first linkage member 233 is connected to a corresponding first moving member 232, each first linkage member 233 is spaced apart along the length of the template body 211, and each first moving member 232 is connected to two first moving racks 2312. The number of the second moving members 234 and the second linkage members 235 is at least two, each second linkage member 235 is connected to a corresponding second moving member 234, each second linkage member 235 is spaced apart along the length of the template body 211, and each second moving member 234 is connected to two second moving racks 2313. Since the length dimension of the prefabricated guardrail 22 is relatively large, and thus the length dimension of the template body 211 is relatively large, the reliability of the drive can be improved by providing at least two first moving members 232 and first linkage members 233 to synchronously drive the movement of the template body 211.

[0062] For example, in this embodiment, the number of the first moving members 232 and the number of the first linkage members 233 are both two, and the two first linkage members 233 are evenly spaced and arranged on one template body 211. The number of the second moving members 234 and the number of the second linkage members 235 are both two, and the two second linkage members 235 are evenly spaced and arranged on the other template body 211.

[0063] See Figures 9 to 11 In one embodiment, a driving cavity 140 is further provided on the frame 10. The driving cavity 140 is located on the side of the rotating shaft 213 facing away from the template body 211. The driving unit 231 is arranged in the driving cavity 140. The frame 10 is further provided with a first moving groove 150 and a second moving groove 160. The length directions of the first moving groove 150 and the second moving groove 160 are both in the demolding direction a. The first moving groove 150 and the second moving groove 160 are both located between the driving cavity 140 and the rotating groove 110, and one end of the first moving groove 150 and one end of the second moving groove 160 are both aligned with the driving cavity. 140 is connected, the other end of the first movable groove 150 passes through one side wall of the frame 10, and the other end of the second movable groove 160 passes through the other side wall opposite to the frame 10. One end of the first movable member 232 is arranged in the first movable groove 150 and can move in the first movable groove 150, and the other end extends out of the first movable groove 150 and is rotatably connected to the first linkage member 233. One end of the second movable member 234 is arranged in the second movable groove 160 and can move in the second movable groove 160, and the other end extends out of the second movable groove 160 and is rotatably connected to the second linkage member 235. By setting the driving cavity 140, the installation of the driving unit 231 can be facilitated, and by setting the first movable groove 150 and the second movable groove 160, the installation and mobile drive of the first movable member 232 and the second movable member 234 can be facilitated. By setting the driving cavity 140 at the top, the first movable groove 150 and the second movable groove 160 at the middle, and the rotating groove 110, the connecting groove 120 and the limiting groove 130 at the bottom, the interference of the movement of each component can be avoided, and the linkage movement between the components can be effectively realized.

[0064] See Figure 2 In one embodiment, there are two second drive assemblies 240, each of which is used to drive the rotation of the two clamping plate assemblies 220. By providing two second drive assemblies 240 to drive the rotation of the two clamping plate assemblies 220, it is convenient to control the demolding separately and ensure the reliability of the demolding.

[0065] Specifically, one end of each second drive assembly 240 is rotatably connected to the corresponding clamping plate assembly 220, and the other end is rotatably connected to the frame 10. The second drive assembly 240 is retractable to drive the corresponding clamping plate assembly 220 to rotate relative to the frame 10. For example, the second drive assembly 240 can be a hydraulic drive structure, or the second drive assembly 240 can also be an electric push rod or other structure.

[0066] In other embodiments, the number of second drive assembly 240 can be one, with one second drive assembly 240 driving the two clamping plate assemblies 220 to rotate synchronously toward or away from each other. For example, the second drive assembly 240 can be a rack and pinion structure, which drives the two racks on either side to move synchronously toward or away from each other by rotating the driving gear 2314. For example, the second drive assembly 240 can be a nut and screw structure, which drives the screw to rotate to achieve synchronous movement of two nuts disposed at different threaded positions toward or away from each other.

[0067] See again Figure 1 In one embodiment, there are at least two mold mechanisms 20, each of which is spaced apart above the conveying mechanism 30 along the conveying direction of the conveying mechanism 30. The number of support mechanisms 40 matches the number of mold mechanisms 20, and the conveying mechanism 30 can simultaneously transport each support mechanism 40 to the bottom of the corresponding mold mechanism 20. By providing at least two mold mechanisms 20 and cooperating with corresponding support mechanisms 40, each mold mechanism 20 can simultaneously process the prefabricated guardrail 2, thereby improving the processing efficiency of the prefabricated guardrail 2.

[0068] In one embodiment, there are at least two conveying mechanisms 30, each of which is arranged in parallel and spaced apart. At least two mold mechanisms 20 are correspondingly arranged on each conveying mechanism 30. The processing equipment 1 also includes two transverse docking mechanisms 60, which are respectively located at both ends of the conveying mechanism 30. One transverse docking mechanism 60 is used to transport the support mechanism 40 to one end of the conveying mechanism 30 and transport the support mechanism 40 to the conveying mechanism 30, and the other transverse docking mechanism 60 is used to transport the support mechanism 40 transported by the conveying mechanism 30 out of the area where the conveying mechanism 30 is located. The provision of the transverse docking mechanism 60 facilitates the transport of structures such as the support mechanism 40 to the conveying mechanism 30 or the output of the conveying mechanism 30. By providing at least two conveying mechanisms 30, the processing efficiency of the prefabricated guardrail 2 can be further improved.

[0069] In one embodiment, the processing equipment 1 further includes a concrete feeding mechanism 70, which is disposed on one side of the conveying mechanism 30 and is movable along the length of the conveying mechanism 30. The concrete feeding mechanism 70 is used to pour concrete into the pouring space. In this embodiment, the concrete feeding mechanism 70 may be a concrete mixer truck, which directly pours concrete into the pouring space. In other embodiments, the concrete feeding mechanism 70 may also be a device that stores concrete and delivers it to the side of the mold mechanism 20 via a conveyor rail.

[0070] In one embodiment, the processing equipment 1 further includes a transfer mechanism 80, which is disposed on one side of the conveying mechanism 30, with opposite ends of the transfer mechanism 80 docked with two transverse docking mechanisms 60. The processing equipment 1 also includes a rebar cage loading mechanism docked to the transfer mechanism 80 and configured to transport the rebar cage to the support mechanism 40. The provision of the transfer mechanism 80 facilitates the unloading of the prefabricated guardrail 2 and the loading of the rebar cage, and also allows redundant structures such as the support mechanism 40 to be placed on the transfer mechanism 80.

[0071] See also Figure 3 In this embodiment, after the steel cage is placed on the support mechanism 40, the locking assembly 430 on the partition 420 can be driven to lock on the steel cage, ensuring the reliability of the position of the steel cage as the support mechanism 40 moves, and preventing the steel cage from falling during transportation.

[0072] See Figures 1 to 3 In one embodiment, the present application also describes a method for processing a prefabricated guardrail 2, which is applied to the processing equipment 1 in any of the above embodiments. Specifically, the processing method includes:

[0073] Control the oil injection mechanism 50 to be delivered to the bottom of the mold mechanism 20;

[0074] Control the two side template assemblies 210 and the two clamping plate assemblies 220 to surround the oil injection mechanism 50;

[0075] Start the oil spraying mechanism 50 to spray the demoulding oil to the mold;

[0076] Control the flipping of the two side template assemblies 210 and the two clamping plate assemblies 220;

[0077] Control the oil injection mechanism 50 to leave the mold mechanism 20;

[0078] The steel cage feeding mechanism is controlled to transport the steel cage to the support mechanism 40 , and the steel cage is installed on the support mechanism 40 .

[0079] Then the locking assembly 430 is driven to be locked on the steel cage.

[0080] Before casting and forming the prefabricated guardrail 2, demoulding oil is first sprayed on the inner surface of the mold mechanism 20 through the oil spraying mechanism 50 to facilitate the subsequent demoulding of the prefabricated guardrail 2. Then the steel cage is placed on the supporting mechanism 40 to facilitate the loading of the steel cage at one workstation, thereby improving the convenience of loading the steel cage.

[0081] In one embodiment, the processing method further comprises:

[0082] Controlling the conveying mechanism 30 to convey the supporting mechanism 40 to the bottom of the mold mechanism 20;

[0083] Control the two side formwork assemblies 210 and the two clamping plate assemblies 220 to surround the support mechanism 40 to form a pouring space;

[0084] Pouring concrete into the pouring space until the concrete height reaches the preset height;

[0085] When the setting strength of the concrete reaches a preset strength, the two side formwork assemblies 210 and the two clamping plate assemblies 220 are controlled to flip upwards;

[0086] The conveying mechanism 30 is controlled to convey the supporting mechanism 40 to the unloading station of the prefabricated guardrail 2 .

[0087] During demoulding, the mold mechanism 20 and the formed prefabricated guardrail 2 do not need to be flipped, and thus there is no need to set up a large and load-bearing flipping device. During demoulding, it is only necessary to control the two side template components 210 and the splint component 220 to flip upwards. The demoulding process is simple and convenient, and the safety of demoulding is effectively improved.
