[0002] In the field of highway safety facilities, the installation of guardrails plays a vital role in reducing vehicle collision damage and protecting the safety of drivers and passengers. Traditionally, the installation of guardrails mainly relies on on-site casting, which not only has low construction efficiency, but also makes it difficult to ensure the consistency of construction quality. In order to improve construction efficiency and ensure the consistency and reliability of guardrails, prefabricated guardrail technology came into being. Prefabricated guardrails are processed and formed in the factory using a production line, and then transported to the construction site for installation, thereby improving construction efficiency.

DETAILED DESCRIPTION

[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0040] See also Figures 1 to 3 The processing equipment 1 of the prefabricated guardrail 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 of the prefabricated guardrail includes a frame 10, a mold mechanism 20, a conveying mechanism 30 and a supporting mechanism 40. The mold mechanism 20 includes two side template assemblies 210 and two clamping plate assemblies 220. Each side template assembly 210 can be movably arranged on the frame 10, and the two side template assemblies 210 are relatively spaced. Each clamping plate assembly 220 can be movably arranged on the frame 10, and the two clamping plate assemblies 220 are relatively spaced. The conveying mechanism 30 is arranged 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 template assemblies 210 and the two clamping plate assemblies 220 move relative to the frame 10 to the support mechanism 40, and can enclose a casting space together with the support mechanism 40; when demolding, each side template 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] When the prefabricated guardrail 2 is processed, the conveying mechanism 30 conveys the support mechanism 40 to the bottom of the mold mechanism 20, and controls the two side template components 210 and the two clamping plate components 220 to surround the support mechanism 40 to form a casting space. Then pour concrete into the casting space until the concrete height reaches the preset height. When the solidification strength of the concrete reaches the preset strength, the two side template components 210 and the two clamping plate components 220 are controlled to flip upward. Finally, the conveying mechanism 30 is controlled to convey the support mechanism 40 to the unloading station of the prefabricated guardrail 2. When the above-mentioned processing equipment 1 is demoulded, 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-scale flipping device with a strong load-bearing capacity, and there will be no safety accidents caused by the slipping of the prefabricated guardrail 2 during the flipping process. When demoulding, it is only necessary to control the two side template components 210 and the clamping plate components 220 to flip upward. The demoulding process is simple and convenient, and there is no risk of the prefabricated guardrail 2 falling from the mold mechanism 20 during the demoulding process, thereby improving the safety of demoulding.

[0042] See also Figure 2 and Figure 3 In one embodiment, the support mechanism 40 includes a support bottom mold 410 and a separator 420. The support bottom mold 410 is arranged on the conveying mechanism 30. The separator 420 is arranged on the support bottom mold 410. The support bottom mold 410 can enclose a casting space together with two side mold assemblies 210 and two clamping plate assemblies 220. The separator 420 is located in the casting space and can divide the casting space into two casting cavities. The two side mold assemblies 210 are symmetrically arranged relative to the separator 420. By setting the support bottom mold 410, it is convenient to support the weight of the concrete forming the prefabricated guardrail. By setting the separator 420, it is convenient to cast and form two prefabricated guardrails 2 at the same time. The two prefabricated guardrails 2 formed are arranged opposite to each other, which improves the efficiency of forming the prefabricated guardrail 2. Due to the setting of the separator 420, the two side mold assemblies 210 can be set to the same structure, reducing the structural complexity of the mold mechanism 20. In this embodiment, the separator 420 is fixed on the support bottom mold 410, for example, it can be integrally formed with the support bottom mold 410. In other embodiments, the partition 420 may also be clamped on the supporting bottom mold 410 by means of a clamping structure or the like.

[0043] See also Figure 7 In one embodiment, the support mechanism 40 further includes a clamping assembly 430, which is disposed on the top of the partition 420. The clamping assembly 430 is movable relative to the partition 420 and clamped on the side of the prefabricated guardrail 2 that faces away from the partition 420. After the prefabricated guardrail 2 is formed and demoulded, the side of the prefabricated guardrail 2 that faces away from the partition 420 is completely exposed to the outside, and the conveying mechanism 30 needs to convey the support mechanism 40 with the prefabricated guardrail 2 to the unloading station. Therefore, by setting the clamping assembly 430 to clamp the side of the prefabricated guardrail 2 that faces away from the partition 420, the possibility of the prefabricated guardrail 2 tipping over during the conveying process is reduced, thereby ensuring the stability and safety during the conveying process.

[0044] Specifically, the clamping assembly 430 includes a clamping member 431 and a rotating driving member 432. The clamping member 431 includes a connecting portion 433 and a clamping portion 434 disposed on the connecting portion 433. One end of the connecting portion 433 away from the clamping portion 434 is connected to the rotating driving member 432. The rotating driving member 432 is disposed on the partition 420. The rotating driving member 432 is used to drive the clamping member 431 to rotate so that the clamping portion 434 can rotate to the side of the prefabricated guardrail 2 that is away from the partition 420. The prefabricated guardrail 2 is restricted on the partition 420 by the clamping portion 434, thereby 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 respectively in the directions of the two casting cavities, 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 the largest on the supporting bottom mold 410. Specifically, the end of the prefabricated guardrail 2 with a larger cross-section is located at the bottom, and the end with a smaller cross-section is located at the top, so that the prefabricated guardrail 2 after demoulding can be more stably arranged on the supporting bottom mold 410, reducing the possibility of the prefabricated guardrail 2 overturning after demoulding.

[0047] See also Figure 1 , Figure 4 and Figure 5 In one embodiment, the processing equipment 1 further includes an oil spraying mechanism 50, which is arranged on the conveying mechanism 30. The conveying mechanism 30 is used to convey the oil spraying mechanism 50 to the bottom of the mold mechanism 20. The two side template assemblies 210 and the two clamping plate assemblies 220 can be relatively movable relative to the frame 10 to surround the oil spraying mechanism 50. The oil spraying mechanism 50 is used to spray demoulding oil onto the inner wall of the side template assembly 210 and the inner wall of the clamping plate assembly 220. By setting the oil spraying mechanism 50, it is possible to spray demoulding oil onto the side template assembly 210 and the clamping plate assembly 220, so that after the subsequent formation of the prefabricated guardrail 2, the side template assembly 210 and the clamping plate assembly 220 can be driven to flip to complete demoulding, thereby improving the convenience of demoulding. After the conveying mechanism 30 conveys the formed prefabricated guardrail 2 away from the mold mechanism 20, the conveying mechanism 30 conveys the oil spraying mechanism 50 to the mold mechanism 20, effectively improving the processing efficiency of the prefabricated guardrail 2.

[0048] Specifically, the oil injection mechanism 50 includes an oil injection body 510, a nozzle 520, a rotating drive component 530, an oil pump 540 and an oil storage tank 550. The oil injection body 510 is arranged on the conveying mechanism 30, and the nozzle 520 is rotatably arranged on the oil injection body 510. The rotating drive component 530 is used to drive the nozzle 520 to rotate on the oil injection body 510. An oil injection channel is formed in the nozzle 520. The oil pump 540 and the oil storage tank 550 are both arranged on the oil injection body 510. The oil pump 540 connects the oil injection 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 injection channel. The oil pump 540 can spray the demoulding oil stored in the oil tank 550 onto the side template assembly 210 and the clamping plate 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 by the nozzle 520 can be more evenly attached to the side template assembly 210 and the clamping plate assembly 220.

[0049] In the embodiment, the spray head 520 includes a spray part 521 and a rotating body 522 disposed on the spray part. The rotating body 522 is hollow and penetrated with an oil inlet pipe 560, and an oil injection channel is formed in the oil inlet pipe 560. The rotating body 522 is rotatably penetrated on the oil injection body 510. A spray chamber 523 connected to the space inside the rotating body 522 is formed in the spray part 521, and a spray hole 524 connected to the spray chamber 523 is formed on the outer wall of the spray part 521. The rotary drive member 530 can drive the rotating body 522 through the transmission member to drive the spray part 521 to rotate relative to the oil inlet pipe 560 and the oil injection body 510. The oil inlet pipe 560 is connected to the oil storage tank 550 through the oil pump 540, and the oil pump 540 pumps the demoulding oil to the oil inlet pipe 560, and then pumps it into the injection chamber 523.

[0050] In one embodiment, the oil injection mechanism 50 further includes a filter 570. An oil receiving groove 512 is formed on the upper surface of the oil injection body 510. A filter hole 514 is formed on the bottom wall of the oil receiving groove 512. The filter hole 514 is provided with a filter 570, and the filter hole 514 is connected to the space in the oil storage tank 550. The oil receiving groove 512 can be provided to recover the demoulding oil dripping from the side mold assembly 210 and the clamping plate assembly 220. The recovered demoulding oil is recovered after being filtered by the filter 570, thereby avoiding waste of the demoulding oil.

[0051] Specifically, the oil receiving groove 512 is an annular groove around the nozzle 520. Along the outward direction of the nozzle 520, the bottom wall height of the annular groove first decreases and then increases. A filter hole 514 is provided on the bottom wall at the lowest point of the annular groove. By setting the oil receiving groove 512, the demoulding oil in the oil receiving groove 512 can effectively flow to the filter hole 514, thereby improving the recovery efficiency.

[0052] See also 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 a demolding direction a, and the direction in which one side template assembly 210 moves toward the other side template assembly 210 is a closing direction b. The first drive assembly 230 is disposed on the frame 10, and the first drive assembly 230 is used to drive the two side template assemblies 210 to move a 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, and the second drive assembly 240 is used to drive the clamping plate assembly 220 to flip upward or downward. Figure 2 and Figure 4 As shown, for the side template assembly 210 on the left, the demoulding direction a is to the left, and the mold closing direction b is to the right; for the side template assembly 210 on the right, 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 driving 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 the 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 to pass through, or a positioning column structure for forming the reserved hole of the precast guardrail 2, the first driving 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 forming of the prefabricated guardrail 22 is ensured.

[0054] See also Figure 3 , Figures 6 to 8 In one embodiment, the side template assembly 210 includes a template body 211, a connecting member 212, a rotating shaft 213 and a stopper 214. The connecting member 212 is connected to one end of the template body 211. The rotating shaft 213 and the stopper 214 are both arranged on the side of the connecting member 212 away from the template body 211. The direction of the stopper 214 toward the rotating shaft 213 is the demoulding direction a, and the axis of the rotating shaft 213 intersects with the demoulding direction a. The frame 10 is formed with a rotating groove 110, a connecting groove 120 and a stopper 130. The rotating groove 110 is connected with the stopper 130 through the connecting groove 120. The direction of the stopper 130 toward the rotating groove 110 is the demoulding direction a. The connecting groove 120 penetrates the frame 10 and forms a rotating opening 122 on one side of the template body 211. In the mold closing casting state, the stopper 214 is located in the stopper 130, and the rotating shaft 213 is at least partially or completely located in the rotating 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 of the template component 210 and drives the limiting member 214 to rotate in the direction of the rotating mouth 122.

[0055] By setting the positional relationship between the rotating shaft 213 and the stopper 214 and the rotating groove 110 and the stopper groove 130 on the frame 10, when the first driving assembly 230 drives the template body 211 to move, the stopper 214 is located in the stopper groove 130, thereby limiting the template body 211 to move only. At this time, by controlling the moving distance of the stopper 214 to the rotating opening 122, the demoulding distance of the template body 211 can be controlled. When the stopper 214 moves into the connecting groove 120, the limiting effect of the stopper groove 130 and the stopper 214 is eliminated, and the rotating shaft 213 can rotate in the rotating groove 110 again, and then the first driving assembly 230 can drive the template body 211 to rotate relative to the frame 10 through the rotating shaft 213. At this time, the stopper 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 driving 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, and the limiting member 214 moves into the connecting groove 120 and is located at 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 Fig. 9In this embodiment, the first driving assembly 230 includes a driving 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 a 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 another template body 211, and the other end is rotatably connected to the second moving member 234. The driving unit 231 is used to drive the first moving member 232 and the second moving member 234 to move along the demoulding direction a or the mold closing direction b. When the first moving member 232 is driven to move by the driving 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 demoulding direction a through the first linkage member 233. When the stopper 214 moves into the connecting groove 120, the limiting effect of the stopper 214 is released, and 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, and 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, without switching 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 driving unit 231 is used to drive the first moving member 232 and the second moving member 234 to move synchronously in opposite directions or in opposite directions. The driving unit 231 drives the first moving member 232 and the second moving member 234 to operate synchronously, thereby improving the demoulding and clamping efficiency of the two template bodies 211. In other embodiments, there may be two driving units 231, and the two driving units 231 drive the first moving member 232 and the second moving member 234 to move respectively.

[0059] See also Figure 3 , Figure 6 and Fig. 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, the second moving rack 2313 is connected to the second moving member 234, and the first moving rack 2312 and the second moving rack 2313 are both meshed with the transmission gear set. The driving power source 2311 is used to drive the transmission gear set to rotate, so as to drive 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 is used to realize the synchronous movement of the first moving rack 2312 and the second moving rack 2313 in opposite directions or toward each other, thereby realizing the synchronous movement of the first moving member 232 and the second moving member 234 in opposite directions or toward each other.

[0060] In this embodiment, the number of the first moving rack 2312 and the second moving rack 2313 is two, the two first moving racks 2312 are arranged at intervals, and the two second moving racks 2313 are respectively located on the outsides of the two first moving racks 2312 and are respectively arranged at intervals from the first moving 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 moving racks 2312, each second moving rack 2313 is meshed with the adjacent first moving rack 2312 through 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 moving racks 2312 are connected to the first moving member 232, and the two second moving racks 2313 are connected to the second moving member 234. By setting two first moving racks 2312 to synchronously drive a template body 211 to move, the reliability of driving the template body 211 can be improved. Similarly, by using two second moving racks 2313 to synchronously drive another template body 211 to operate, the reliability of driving the template body 211 can be improved. The moving directions of each first moving rack 2312 and second moving rack 2313 are limited by the driving gear 2314, the first gear 2315 and the two second gears 2316 to achieve synchronous movement toward or away from each other. 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 member 232 and the first linkage member 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 arranged at intervals along the length direction 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 member 234 and the second linkage member 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 arranged at intervals along the length direction 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 large, which leads to the large length dimension of the template body 211, the reliability of the drive can be improved by arranging at least two first moving members 232 and the first linkage member 233 to synchronously drive the template body 211 to move.

[0062] For example, in this embodiment, the number of first moving members 232 and 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 second moving members 234 and 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.

By setting the driving cavity 140, the installation of the driving unit 231 can be easily realized, and by setting the first movable groove 150 and the second movable groove 160, the installation and movable drive of the first movable member 232 and the second movable member 234 can be easily realized. Moreover, 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, interference of the movement of each component can be avoided, and the linkage movement between the components can be effectively realized.

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

[0065] Specifically, one end of each second driving assembly 240 is rotatably connected to the corresponding clamping plate assembly 220, and the other end is rotatably connected to the frame 10, and the second driving assembly 240 can be extended to drive the corresponding clamping plate assembly 220 to rotate relative to the frame 10.

[0066] In other embodiments, the number of the second drive assembly 240 may be one, and one second drive assembly 240 drives the two clamping plate assemblies 220 to rotate synchronously toward or away from each other. For example, the second drive assembly 240 may be a gear rack structure, which is synchronously driven to move toward or away from the two racks on both sides by driving the gear 2314 to rotate. For example, the second drive assembly 240 may be a nut screw structure, which is synchronously driven to move toward or away from each other by driving the screw rod to rotate.

[0067] See again Figure 1 In one embodiment, the number of the mold mechanisms 20 is at least two, and each mold mechanism 20 is arranged above the conveying mechanism 30 at intervals along the conveying direction of the conveying mechanism 30.

[0068] In one embodiment, the number of conveying mechanisms 30 is at least two, and each conveying mechanism 30 is arranged in parallel and spaced apart, and at least two mold mechanisms 20 are correspondingly arranged on each conveying mechanism 30, and the processing equipment 1 also includes two transverse docking mechanisms 60, and the two transverse docking mechanisms 60 are respectively located at the two ends of the conveying mechanism 30, one transverse docking mechanism 60 is used to convey the support mechanism 40 to one end of the conveying mechanism 30, and convey the support mechanism 40 to the conveying mechanism 30, and the other transverse docking mechanism 60 is used to convey the support mechanism 40 conveyed by the conveying mechanism 30 out of the area where the conveying mechanism 30 is located.

In this embodiment, the concrete feeding mechanism 70 can be a concrete mixer truck, and the concrete is directly poured into the pouring space by the concrete mixer truck. In other embodiments, the concrete feeding mechanism 70 can also be a device for storing concrete that is transported to one side of the mold mechanism 20 through a conveying guide rail.

[0070] In one embodiment, the processing equipment 1 further includes a transfer mechanism 80, which is arranged on one side of the conveying mechanism 30, and the two opposite ends of the transfer mechanism 80 are respectively connected to the two transverse docking mechanisms 60; the processing equipment 1 also includes a steel cage feeding mechanism, which is connected to the transfer mechanism 80, and the steel cage feeding mechanism is used to convey the steel cage to the support mechanism 40. By setting the transfer mechanism 80, it is convenient to realize the steps of unloading the prefabricated guardrail 2 and loading the steel cage, and it is also possible to place redundant support mechanisms 40 and other structures 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 also Figures 1 to 3 In one embodiment, the present application also describes a processing method for a prefabricated guardrail 2, which is applied to the processing equipment 1 in any of the above embodiments. Specifically, the processing method includes:

[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 supporting mechanism 40 , and the steel cage is installed on the supporting 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 injection mechanism 50 to facilitate the subsequent demoulding of the prefabricated guardrail 2, and then the steel cage is placed on the support mechanism 40 to facilitate the loading of the steel cage at one workstation, thereby improving the convenience of loading the steel cage.

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.
