Description

Technical Field

[0001] This invention relates to a construction device and method for a double-layer, double-wave guardrail, belonging to the field of screening technology. Background Technology

[0002] Corrugated beam guardrails are a common traffic safety facility. They absorb impact through deformation, effectively preventing vehicles from running off the road due to loss of control, thus protecting vehicles and pedestrians. In accident-prone areas, single-layer corrugated beam guardrails may not provide sufficient protection, therefore, they need to be upgraded to higher levels. Figure 12 The double-layer, double-wave guardrail shown is designed to enhance safety and ensure that its safety performance meets the protection requirements of current regulations.

[0003] During the reconstruction, multiple additional holes are typically machined on the existing single-layer corrugated beam guardrail shoulder. Then, additional posts are inserted into these holes one by one. Finally, the disassembled single-layer corrugated beam plate is fastened to the inserted additional posts to complete the reconstruction. However, to facilitate the installation of the additional posts, the size of the machined additional holes is usually larger than the size of the additional posts, resulting in gaps between the additional posts and the additional holes after installation. To ensure the installation of the additional posts is firm and to reduce material waste, the milling material generated during the reconstruction is usually used to fill the gaps, thus achieving the reuse of waste.

[0004] Filling each gap individually with materials would increase the number of renovation procedures and time. Furthermore, some of the milled material particles are relatively large and are prone to clogging at the gap openings during the filling process, resulting in a higher probability of unfilled voids and poor filling effect, which would affect the quality of the double-layer double-wave guardrail construction.

The multiple convex wheels are respectively located in multiple inner grooves of the wave plate.

[0016] A method for constructing a double-layer, double-wave guardrail, using any one of the above-described double-layer, double-wave guardrail construction devices, includes the following steps:

[0017] The first step is pre-processing. First, multiple reinforced columns are installed at equal intervals on the right end of the disassembled upper corrugated beam plate. Then, the H-shaped top plate is installed on the reinforced columns using hexagonal bolts, so that the upper corrugated beam plate, multiple reinforced columns, and multiple H-shaped top plates form an upper corrugated guardrail structure. Then, the milled material generated from the reconstruction is put into the bottom box, so that the milled material generated from the reconstruction falls onto the upper end of the screen plate. Then, the bottom box and other components are moved by four rolling components, so that the bottom box is moved to the position where the upper corrugated guardrail structure is placed.

[0018] The second step is material loading. The first driving device drives the first bidirectional screw to rotate, thereby causing multiple first nut seats and multiple second nut seats to move outward, which in turn causes multiple first arms and multiple second arms to unfold, causing the movable frame and other parts to move to the right, and then the upper corrugated beam plate to pass through the gap between the F-type clamp and the rubber hammer and move to the appropriate position. At this time, there are two F-type clamps between two adjacent reinforced columns. Then, the second driving device drives the multi-section bidirectional screw to rotate, causing the two adjacent F-type clamps to move inward, and then multiple reinforced columns are clamped. At this time, the two transverse parts of the H-shaped top plate are respectively located in the grooves of two adjacent L-shaped plates, and the hexagonal nuts of the hexagonal bolts are located in the corresponding hexagonal sleeves. Then, the lifting device moves the U-shaped frame and other parts upward, thereby lifting the upper wave guardrail structure. Then, the upper wave guardrail structure is moved to the construction position by four rolling components and the base box and other components.

[0019] The third step is installation. The U-shaped frame and other components are moved downward by the lifting equipment, thereby moving the upper wave guardrail structure down and inserting the multiple reinforced posts on the upper wave guardrail structure into the multiple reinforced holes processed on the road shoulder. Then, the fourth drive device drives the worm gear to rotate, thereby rotating multiple convex wheels and multiple worm wheels. The multiple convex wheels and four elastic elements make the screen plate vibrate, so that the qualified milled material on the screen plate passes through the screen plate and falls into the multiple inner grooves of the wave plate. The multiple worm wheels make multiple spiral rods rotate, thereby pushing the milled material in the inner grooves of the wave plate to the opening position of the discharge pipe. The milled material is then transported through the discharge pipe into the gap formed by the reinforced posts and the reinforced holes, thereby completing the filling operation.

[0020] Step 4: Assembly. The rack moves outward using the second telescopic device, causing the ring gear and hexagonal sleeve to rotate in the opposite direction. This causes the hexagonal bolt to rotate and move outward a certain distance. Then, the push plate moves to the left along the groove using the first telescopic device, causing the H-shaped top plate to move to the left and contact the lower corrugated beam plate. Then, the hexagonal bolt is rotated forward using the second telescopic device, rack, ring gear, and hexagonal sleeve. The hexagonal bolt is then used to re-tighten the H-shaped top plate and the reinforced column, thus assembling the reinforced column and the lower corrugated beam plate.

[0021] Step 5: Remove the components. Using the second drive device and multi-section bidirectional screw, move the two adjacent F-type clamps outward, thereby releasing the clamps on the reinforced columns. At this point, the H-type top plate and L-type plate separate. Then, using the third drive device, rotate the two wheels and the rotating frame. With the assistance of multiple drive plates, multiple functional plates, and guide frames, move multiple rubber hammers up and down in a cyclical motion, thereby striking the multiple reinforced columns. Then, using the third telescopic device, rotate the L-type plate 90°, and then move the bottom box and other components, allowing the F-type clamps, L-type plates, and other components to move out of the space between the upper and lower corrugated beam plates.

[0022] The beneficial effects of this invention are:

[0023] 1. The screen plate undergoes a cyclic shaking motion through a first motor, worm gear, multiple convex wheels, and four springs. This causes the screen plate to screen the milled material, which then enters multiple inner grooves in the corrugated plate. With the assistance of multiple worm gears, multiple spiral rods rotate synchronously, pushing the milled material in the inner grooves of the corrugated plate to the right and into the discharge pipe. The discharge pipe then transports the milled material to the gap between the dense posts and the dense holes, achieving screening and synchronous multi-hole filling of the milled material. This improves the filling effect, effectively reduces construction steps and time, and effectively ensures the construction quality of the double-layer double-wave guardrail.

[0024] 2. By using the fourth motor, multiple bidirectional screws, and multiple F-type clamps, multiple reinforced posts are synchronously clamped. Then, using the first electric push rod, multiple reinforced posts of the upper wave guardrail structure are inserted into multiple reinforced holes respectively, realizing mechanical synchronous construction operation. This effectively reduces the probability of construction failure due to errors, effectively reduces construction procedures and time, and effectively ensures the construction quality of double-layer double-wave guardrail.

[0025] 3. Using the fifth electric push rod and push plate, the H-shaped top plate is brought into contact with the lower corrugated beam plate. Then, through the fourth electric push rod, rack, ring gear, and hexagonal sleeve, the hexagonal bolts are used to restrict the installation of the H-shaped top plate. At this time, the H-shaped top plate supports the lower corrugated beam plate, thereby allowing the reinforced columns to strengthen the lower corrugated beam plate. This effectively ensures the protection level of the reconstructed guardrail. The mechanical operation between the H-shaped top plate and the lower corrugated beam plate is achieved, effectively reducing construction procedures and time, reducing the probability of damage to the lower corrugated beam plate, and ensuring normal mechanical synchronous construction operations, thus effectively guaranteeing the construction quality of the double-layer double-wave guardrail.

[0026] 4. Through a third motor, two rotating wheels, a rotating frame, and multiple drive plates, and with the assistance of a guide frame and a rectangular groove, multiple functional plates and multiple rubber hammers move up and down in a cyclical motion. This allows the multiple up-and-down moving rubber hammers to strike the multiple encrypted posts inserted into the encrypted holes, thereby compacting the milled material in the gaps between the encrypted posts and the encrypted holes. This improves the filling quality of the milled material, effectively reduces the probability of voids appearing in the gaps after filling, and effectively ensures the construction quality of the double-layer double-wave guardrail.

[0027] 5. By using multiple second electric push rods, the structure formed by multiple functional rods and multiple first flexible rods is deformed, thus making the structure V-shaped. At the same time, the second flexible rods, flexible shafts, and rectangular flexible rods are deformed, thereby deforming the multi-section bidirectional screw formed by multiple second bidirectional screws and multiple second flexible rods, the rotating frame formed by multiple rotating shafts and multiple flexible shafts, and the guide frame formed by multiple rectangular rods and multiple rectangular flexible rods. This enables effective mechanical synchronous construction of the V-shaped double-layer double-wave guardrail, effectively reducing construction procedures and time, effectively reducing the probability of damage to the lower corrugated beam plate, and effectively ensuring the construction quality of the double-layer double-wave guardrail.

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] Example 1: As Figures 1-5 As shown, a double-layer double-wave guardrail construction device is provided, including a base box 1. Four rolling components are respectively installed at the four corner positions of the lower end of the base box 1. The four rolling components work together to enable the base box 1 to move. The rolling components can be moving wheels. A wave plate 16 arranged along the length of the base box 1 is set inside the base box 1. The wave plate 16 is used to collect the screened milled material and divide the screened milled material into multiple parts. A screen plate 14 located on the upper side of the wave plate 16 is movably installed inside the base box 1. The screen plate 14 is used to screen the milled material generated during the reconstruction. Four elastic elements 13 are respectively installed between the four corner positions of the upper end of the screen plate 14 and the four corner positions of the top end of the base box 1. The four elastic elements 13 work together to make the screen plate 14 movably connected to the base box 1. The elastic elements 13 can be springs.

[0046] Multiple horizontally arranged spiral rods 15, located in multiple inner grooves of the corrugated plate 16, are equidistantly rotatably connected to the inside of the base box 1. The spiral rods 15 push the screened milling material into the discharge pipe 12. Multiple discharge pipes 12, which are arranged in a left-high-right-low angle and are connected to multiple inner grooves of the corrugated plate 16, are equidistantly connected to the right end of the base box 1. The multiple discharge pipes 12 work together to convey the milling material outward. A worm gear 18, which passes through the corrugated plate 16 and is rotatably connected to the corrugated plate 16, is rotatably connected to the inside of the base box 1. The worm gear 18 causes multiple worm wheels 17 and multiple convex wheels 19 to rotate.

[0047] The fixed part of the fourth drive device, which connects the output shaft to the worm gear 18, is installed on the outer end of the base box 1. The worm gear 18 is driven to rotate by the fourth drive device, which can be a first motor 11. Multiple worm wheels 17, which are respectively located at the outer ends of the shafts of multiple spiral rods 15 and in multiple grooves of the wave plate 16, are equidistantly meshed on the lower end of the worm gear 18. The spiral rods 15 are rotated by the worm wheels 17. Multiple convex wheels 19, which are alternately arranged with the worm wheels 17 in multiple grooves of the wave plate 16, are equidistantly arranged on the outer end of the worm gear 18. The multiple convex wheels 19 work together to make the screen plate 14 move upward.

[0048] In use, firstly, multiple reinforced posts 1001 are installed at equal intervals on the right end of the disassembled upper corrugated beam 1002. Then, the H-shaped top plate 1004 is installed on the reinforced posts 1001 using hexagonal bolts 1041, so that the upper corrugated beam 1002, multiple reinforced posts 1001 and multiple H-shaped top plates 1004 form an upper corrugated guardrail structure. Then, the milling material generated from the reconstruction is evenly poured into the bottom box 1, so that the milling material generated from the reconstruction is laid flat and falls onto the upper end of the screen plate 14. Then, the bottom box 1 and other components are moved by four moving wheels, so that the bottom box 1 is moved to the construction position and the outlets of multiple discharge pipes 12 are aligned with the multiple reinforced holes processed on the road shoulder. Then, the multiple reinforced posts 1001 of the upper corrugated guardrail structure are inserted into the multiple reinforced holes respectively.

[0049] Then the first motor 11 is started, which drives the worm gear 18 to rotate, thereby causing multiple convex wheels 19 to rotate. When the protrusion of the convex wheel 19 contacts the lower end of the screen plate 14, the rotating convex wheel 19 will cause the screen plate 14 to move upward, thereby compressing the four springs and generating elastic force. When the protrusion of the convex wheel 19 separates from the lower end of the screen plate 14, the screen plate 14 will move downward under the action of the elastic force of the four springs, realizing the up-and-down cyclic shaking motion of the screen plate 14, thereby enabling the screen plate 14 to screen the milled material, and causing the screened milled material to enter the multiple inner grooves of the corrugated plate 16 respectively.

[0050] During the rotation of the worm gear 18, multiple worm wheels 17 rotate synchronously, which in turn causes multiple spiral rods 15 to rotate synchronously. This pushes the milled material in the inner groove of the wave plate 16 to the right and into the discharge pipe 12. Then, the discharge pipe 12 is used to transport the milled material to the gap formed between the densified post 1001 and the densified hole, thereby screening the milled material and performing multi-hole synchronous filling operations, improving the filling effect, effectively reducing construction procedures and time, and effectively ensuring the construction quality of the double-layer double-wave guardrail.

[0051] Example 2: To improve vehicle traffic capacity, highway guardrails are typically renovated. To save materials, the beams and slabs of the guardrail are usually dismantled for renovation. During construction, multiple additional holes are first drilled in the shoulder, and then additional posts 1001 are inserted into these holes sequentially. The dismantled beams and slabs are then fastened to the inserted additional posts 1001 to complete the renovation. However, these procedures are all performed on-site, increasing the number of steps and time required for the renovation. Furthermore, since the additional posts 1001 are installed independently, misalignment and other errors are likely to occur, increasing the probability of subsequent dismantling and installation of the beams and slabs failing to proceed properly. This can affect the construction quality of the double-layer, double-wave guardrail.

[0052] To solve the above problems, such as Figure 1 , Figure 2 and Figure 9 As shown, the lifting device is installed in the middle between the base box 1 and the U-shaped frame 2 located directly above the base box 1. The lifting device drives the U-shaped frame 2 to move up and down. The lifting device can be a first electric push rod 24, and four telescopic rods are respectively set at the four corner positions between the base box 1 and the U-shaped frame 2. The four telescopic rods work together to guide the movement of the U-shaped frame 2. The first bidirectional screw 25 is rotatably connected between the two vertical parts of the U-shaped frame 2. The first bidirectional screw 25 causes the multiple first nut seats 23 and multiple second nut seats 26 to move relative to each other. The fixing part of the first drive device, which is connected to the output shaft and the first bidirectional screw 25, is installed on the front end of the U-shaped frame 2. The first drive device drives the first bidirectional screw 25 to rotate. The first drive device can be a second motor 21.

[0053] Multiple first nut seats 23 are threaded at equal intervals to the outer front end of the first bidirectional screw 25, providing a mounting carrier for the first support arm 22. Multiple second nut seats 26 located behind the first nut seats 23 are threaded at equal intervals to the outer rear end of the first bidirectional screw 25, providing a mounting carrier for the second support arm 27. Two guide rods located on the left and right sides of the first bidirectional screw 25, passing through the multiple first nut seats 23 and the multiple second nut seats 26 and respectively slidably connected to the multiple first nut seats 23 and the multiple second nut seats 26, are symmetrically installed between the two vertical parts of the U-shaped frame 2. The two guide rods work together to guide the movement of the multiple first nut seats 23 and the multiple second nut seats 26.

[0054] Multiple first arms 22, each with one end movably mounted on the left end of a movable frame 3 located on the right side of the base box 1, are movably mounted on the right ends of multiple first nut seats 23. The first arms 22 connect the first nut seats 23 to the movable frame 3. Multiple second arms 27, each with one end movably mounted on the left end of the movable frame 3, are movably mounted on the right ends of multiple second nut seats 26. The second arms 27 connect the second nut seats 26 to the movable frame 3. The first arms 22 and the second arms 27 form a V-shaped structure that is narrower on the left and wider on the right. The first arms 22 and the second arms 27 work together to make the movable frame 3 move left and right.

[0055] The transverse portions of two L-shaped fixing plates 4 are respectively installed on the front and rear ends of the movable frame 3. The two L-shaped fixing plates 4 work together to provide a mounting carrier for components such as the multi-section bidirectional screw 54. The multi-section bidirectional screw 54 located on the right side of the movable frame 3 is rotatably connected between the two L-shaped fixing plates 4. Through the multi-section bidirectional screw 54, the two adjacent F-shaped clamping plates 5 that work together move relative to each other. Then, the fixing part of the second drive device, which is connected to the output shaft and the multi-section bidirectional screw 54, is installed on the front end of the transverse portion of the L-shaped fixing plate 4 located on the front side. Through the second drive device, the multi-section bidirectional screw 54 is driven to rotate. The second drive device can be a fourth motor 55. Multiple F-shaped clamping plates 5 that are slidably connected to the right end of the movable frame 3 are equidistantly threaded to the outer end of the multi-section bidirectional screw 54, and the two adjacent F-shaped clamping plates 5 are arranged opposite each other. Through the relative arrangement and the cooperation of the two adjacent F-shaped clamping plates 5, the densified column 1001 can be clamped.

[0056] In use, firstly, multiple reinforced columns 1001 are installed at equal intervals on the right end of the disassembled upper corrugated beam plate 1002. Then, the H-shaped top plate 1004 is installed onto the reinforced columns 1001 using hexagonal bolts 1041, thereby forming an upper corrugated guardrail structure with the upper corrugated beam plate 1002, multiple reinforced columns 1001, and multiple H-shaped top plates 1004. Then, the base box 1 and other components are moved by the moving wheels, thereby moving the base box 1 to the placement position of the upper corrugated guardrail structure.

[0057] Then the second motor 21 is started, thereby driving the first bidirectional screw 25 to rotate, thereby causing multiple first nut seats 23 and multiple second nut seats 26 to move outward, thereby causing multiple first arms 22 and multiple second arms 27 to unfold, thereby causing the movable frame 3 and other parts to move to the right, so that there are two F-type clamps 5 between two adjacent encrypted columns 1001.

[0058] Then, the fourth motor 55 is started to drive the multi-section bidirectional screw 54 to rotate, thereby causing the two adjacent F-type clamps 5 to move inward. Then, the multiple F-type clamps 5 are used to synchronously clamp the multiple encrypted posts 1001. Then, the first electric push rod 24 is started to drive the U-shaped frame 2 and other components to move upward, thereby lifting the upper wave guardrail structure. Then, the upper wave guardrail structure is moved to the construction position through the four rolling components and the base box 1 and other components, and the multiple encrypted posts 1001 of the upper wave guardrail structure are aligned with the multiple encrypted holes respectively.

[0059] Then, the first electric push rod 24 causes the U-shaped frame 2 and other components to move downward, thereby moving the upper wave guardrail structure downward and causing multiple densified posts 1001 on the upper wave guardrail structure to be inserted into multiple densified holes processed on the road shoulder, realizing mechanical synchronous construction operation, effectively reducing the probability of failure to construct normally due to errors, effectively reducing construction procedures and time, and effectively ensuring the construction quality of double-layer double wave guardrail.

[0060] Then, milling material is conveyed into the gap between the densified post 1001 and the densified hole through the discharge pipe 12. Cement concrete is then used to fasten the densified post 1001. This completes the installation of the upper wave guardrail structure at the location of the lower wave guardrail structure formed by the lower wave beam plate 1003 and multiple old posts 1005. This creates a double-layer double-wave guardrail, thereby improving the protection level of the guardrail. The lower wave guardrail structure can be rebuilt using the disassembled upper wave beam plate 1002, saving a lot of materials and having good economic efficiency.

[0061] Example 3: Highway guardrail reconstruction is generally carried out by dismantling the beams and plates of the guardrail. To reduce the reconstruction process and time, the dismantled guardrail beams and plates are first assembled with multiple reinforced posts 1001 in the factory to form a reinforced structure. During construction, multiple reinforced posts 1001 of the reinforced structure are simultaneously inserted into the reinforced holes using mechanical synchronous construction. However, to ensure the protection level of the double-layer double-wave guardrail formed by reconstruction, plates are generally used to connect the reinforced posts 1001 to the beams and plates of the old guardrail. Since the beams and plates of the old guardrail are generally corrugated, if the plates are installed on the reinforced posts 1001 first during mechanical operation, the plates are prone to impact with the beams and plates of the old guardrail, which may cause damage to the beams and plates of the old guardrail and affect the quality of the reconstructed guardrail. This makes it impossible for the mechanical synchronous construction to operate normally. If the plates are installed after the reinforcement structure is constructed, it will affect the construction process and time.

[0062] To solve the above problems, such as Figure 1 , Figure 7 , Figure 8 , Figure 12 , Figure 13 and Figure 14 As shown, multiple mounting plates 51 are respectively set on the right ends of multiple F-type clamps 5. The mounting plates 51 provide mounting carriers for L-type plates 53. The vertical part of the L-type plates 53, whose horizontal part is located directly below the F-type clamps 5, is hinged to the right end of the mounting plates 51. Two adjacent L-type plates 53 are arranged opposite each other. The L-type plates 53 provide mounting carriers for components such as the second telescopic device. A groove 535 is formed in the horizontal part of the L-type plate 53, which extends outward from the inner end to the left end of the L-type fixed plate 4. The groove 535 provides mounting space for components such as the push plate 536. The vertically arranged push plate 536 is slidably connected in the groove 535. The push plate 536 pushes the H-type top plate 1004 to move to the left. The movable part of the first telescopic device, whose fixed part is installed on the right wall inside the groove 535, is set on the right end of the push plate 536. The first telescopic device drives the push plate 536 to move left and right. The first telescopic device can be a fifth electric push rod 537.

[0063] A hexagonal sleeve 533, extending into the groove 535 and located on the left side of the push plate 536, is rotatably connected to the outward end of the transverse portion of the L-shaped plate 53. The hexagonal bolt 1041 rotates via the hexagonal sleeve 533. A ring gear 532, located on the outer side of the L-shaped plate 53, is positioned on the outer end of the hexagonal sleeve 533. The hexagonal sleeve 533 rotates via the ring gear 532. A transversely arranged rack 534 meshes with the upper end of the ring gear 532. The ring gear 532 rotates via the rack 534. A fixing part is then positioned... The movable part of the second telescopic device at the outward end of the horizontal part of the L-shaped plate 53 is connected to the right end of the rack 534. The rack 534 is driven to move left and right through the second telescopic device. The second telescopic device can be a fourth electric push rod 531. The fixed part of the third telescopic device, which is located on the lower side of the mounting plate 51 and whose movable part is movably mounted on the left end of the vertical part of the L-shaped plate 53 and is arranged with the left side higher than the right side, is movably mounted on the right end of the F-shaped clamp 5. The L-shaped plate 53 is driven to rotate through the third telescopic device. The third telescopic device can be a third electric push rod 52.

[0064] Before use, multiple reinforced posts 1001 are installed at equal intervals on the right end of the disassembled upper corrugated beam plate 1002. Then, the H-shaped top plate 1004 is installed onto the reinforced posts 1001 using hexagonal bolts 1041. Then, the fourth motor 55 and multiple bidirectional screws 54 are rotated to synchronously clamp the multiple reinforced posts 1001 using multiple F-shaped clamps 5. At this time, the two transverse parts of the H-shaped top plate 1004 on the reinforced post 1001 are respectively located in the grooves 535 of the two adjacent L-shaped plates 53, and the hexagonal nuts of the hexagonal bolts 1041 are located in the corresponding hexagonal sleeves 533. Then, the multiple reinforced posts 1001 on the upper corrugated guardrail structure are mechanically inserted into the multiple reinforced holes.

[0065] At this time, the H-shaped top plate 1004 is located outside the lower corrugated beam plate 1003. Then, the fourth electric push rod 531 is activated, thereby driving the rack 534 to move outward, which in turn causes the ring gear 532 to rotate in the opposite direction, thereby causing the hexagonal sleeve 533 to rotate in the opposite direction, which in turn causes the hexagonal nut of the hexagonal bolt 1041 to rotate in the opposite direction and simultaneously causes the hexagonal bolt 1041 to move outward, thereby releasing the restriction of the hexagonal bolt 1041 on the H-shaped top plate 1004. Then, the fifth electric push rod 537 is activated, thereby driving the push plate 536 to move to the left. With the assistance of the through slots 1042 opened in the two transverse parts of the H-shaped top plate 1004, the push plate 536 contacts the H-shaped top plate 1004 and pushes the H-shaped top plate 1004 to move to the left along the groove 535, thereby causing the H-shaped top plate 1004 to contact the lower corrugated beam plate 1003.

[0066] Then, through the fourth electric push rod 531, rack 534 and ring gear 532, the hexagonal sleeve 533 is rotated in the forward direction, which in turn causes the hexagonal bolt 1041 to rotate in the forward direction and move inward, thereby allowing the hexagonal bolt 1041 to re-limit the installation of the H-shaped top plate 1004. At this time, the H-shaped top plate 1004 supports the lower corrugated beam plate 1003, so that the reinforced column 1001 can reinforce the lower corrugated beam plate 1003, thereby effectively ensuring the protection level of the reconstructed guardrail.

[0067] The mechanical operation of connecting the H-shaped top plate 1004 and the lower corrugated beam plate 1003 is realized, which effectively reduces the construction process and time, effectively reduces the probability of damage to the lower corrugated beam plate 1003, and effectively ensures normal mechanical synchronous construction operations, thus ensuring the construction quality of the double-layer double-wave guardrail.

[0068] After the construction of the double-layer double-wave guardrail is completed, the clamping operation on the densified post 1001 is first released. At this time, the H-shaped top plate 1004 and the L-shaped plate 53 are separated. Then, the third electric push rod 52 is activated, thereby driving the L-shaped plate 53 to rotate 90° around the hinge position between the L-shaped plate 53 and the mounting plate 51. This allows the L-shaped plate 53 to move between the upper corrugated beam plate 1002 and the lower corrugated beam plate 1003 in the double-layer double-wave guardrail, effectively ensuring that the L-shaped plate 53 can be separated from the reconstructed double-layer double-wave guardrail.

[0069] Example 4: To improve vehicle traffic capacity, highway guardrails are often rebuilt. To save materials, the beams and slabs of the guardrail are usually dismantled for reconstruction. During construction, multiple densified holes are first processed on the shoulder, and then densified posts 1001 are inserted into these holes sequentially. To ensure easy insertion of the densified posts 1001 into the holes, the size of the densified holes is larger than the size of the densified posts 1001. After the densified posts 1001 are inserted, gaps are formed between them and the holes. Milled material is simultaneously conveyed into these gaps using components such as the bottom box 1, sieve plate 14, and discharge pipe 12. However, the milled material in the gaps tends to be loose, resulting in a higher probability of voids appearing in the gaps after filling, leading to poor filling quality and affecting the construction quality of the double-layer double-wave guardrail.

[0070] To solve the above problems, such as Figure 1 , Figure 2 , Figure 6 and Figure 9As shown, two rotating wheels 42 are rotatably connected to the inward ends of the vertical portions of two L-shaped fixed plates 4. The two rotating wheels 42 work together to provide a mounting carrier for the rotating frame 43. The fixing part of the third drive device, which connects the output shaft to the rotating wheel 42 located on the rear side, is set on the rear end of the vertical portion of the L-shaped fixed plate 4 located on the rear side. The rotating wheel 42 located on the rear side is driven to rotate by the third drive device, which can be a third motor 41. The rotating frame 43, which is eccentrically arranged with the two rotating wheels 42, is set between the two rotating wheels 42. The rotating frame 43 provides a mounting carrier for multiple drive plates 44.

[0071] Multiple drive plates 44 are equidistantly and movably mounted on the outer end of the rotating frame 43. The drive plates 44 provide mounting carriers for the functional plates 45. Multiple vertically arranged functional plates 45 are movably mounted on the lower ends of the drive plates 44. The functional plates 45 provide mounting carriers for the rubber hammers 46. The rubber hammers 46 located on the upper side of the F-shaped clamping plate 5 are mounted on the lower middle part of the functional plates 45. The rubber hammers 46 strike the densified column 1001, forming rectangular grooves 451 that penetrate the functional plates 45 by recessing the front end faces of the multiple functional plates 45. A guide frame 47 that penetrates the multiple rectangular grooves 451 and is slidably connected to the multiple rectangular grooves 451 is set between the vertical parts of the two L-shaped fixed plates 4. The rectangular grooves 451 and the guide frame 47 work together to guide the movement of the functional plates 45.

[0072] Before use, multiple reinforced columns 1001 are installed at equal intervals on the right end of the disassembled upper corrugated beam plate 1002. Then, the H-shaped top plate 1004 is installed onto the reinforced columns 1001 using hexagonal bolts 1041, thereby forming an upper corrugated guardrail structure with the upper corrugated beam plate 1002, multiple reinforced columns 1001, and multiple H-shaped top plates 1004. Then, the fourth motor 55 and multiple bidirectional screws 54 are rotated, thereby using multiple F-type clamps 5 to synchronously clamp the multiple reinforced columns 1001. Then, the multiple reinforced columns 1001 on the upper corrugated guardrail structure are mechanically inserted into multiple reinforced holes.

[0073] The milling material is then fed into the gap between the encrypted post 1001 and the encrypted hole using the discharge pipe 12. At the same time, the third motor 41 is started, which drives the rear rotating wheel 42 to rotate. With the assistance of another rotating wheel 42, the rotating frame 43 rotates around the center line of the rotating wheel 42. This causes the upper part of multiple drive plates 44 to rotate with the rotating frame 43. With the assistance of the guide frame 47 and the rectangular groove 451, multiple functional plates 45 move up and down in a cyclical motion, which in turn causes multiple rubber hammers 46 to move up and down. The multiple up and down moving rubber hammers 46 are used to strike the multiple encrypted posts 1001 inserted into the encrypted holes, thereby compacting the milling material in the gap between the encrypted post 1001 and the encrypted hole. This improves the filling quality of the milling material, effectively reduces the probability of voids in the gap after filling, and effectively ensures the construction quality of the double-layer double-wave guardrail.

[0074] Example 5: To improve vehicle traffic capacity, highway guardrails are often rebuilt. To save materials, the beams and plates of the guardrail are usually dismantled for reconstruction. To reduce the number of reconstruction steps and time, the dismantled guardrail beams and plates are first assembled with multiple reinforced posts 1001 in the factory to form a reinforced structure. During construction, a mechanical synchronous construction device is used to simultaneously insert the multiple reinforced posts 1001 of the reinforced structure into the reinforced holes to form a double-layer double-wave guardrail. At this time, the clamping structure in the mechanical synchronous construction device is in a straight line. However, high-protection guardrails are generally required at highway corners. The required double-layer double-wave guardrail is V-shaped, which makes it impossible to construct the V-shaped reinforcement structure in one go. It is generally constructed in two stages, which increases the probability of damage to the lower wave beam 1003 at the docking position, affecting the construction steps and time.

[0075] To solve the above problems, such as Figure 10 and Figure 11As shown, a plurality of second electric push rods 31, movable rods 32, multiple functional rods 33, and multiple first flexible rods 34 form a movable frame 3. The other ends of multiple first support arms 22 and multiple second support arms 27 are movably mounted on the left end of the movable rod 32. The movable rod 32 provides a mounting carrier for the second electric push rods 31 and other components. The fixing parts of the multiple second electric push rods 31 are equidistantly arranged on the right end of the movable rod 32. The second electric push rods 31 drive the corresponding functional rods 33 to move. The multiple functional rods 33 are then respectively connected to the multiple second... The movable part of the electric push rod 31 is movably connected to provide an installation carrier for components such as the F-type clamp plate 5 through the functional rod 33. Two F-type clamp plates 5 are symmetrically and slidably connected at the right end of the functional rod 33. The front end of the transverse part of the L-type fixing plate 4 located on the rear side is connected to the rear end of the functional rod 33, and the rear end of the transverse part of the L-type fixing plate 4 located on the front side is connected to the front end of the functional rod 33 located on the front side. A first flexible rod 34 is installed between two adjacent functional rods 33, and the two adjacent functional rods 33 are flexibly connected through the first flexible rod 34.

[0076] Multiple second bidirectional screws 541 and multiple second flexible rods 542 form a multi-section bidirectional screw 54. The second bidirectional screws 541 are located to the right of the functional rod 33, and the second flexible rods 542 are located to the right of the first flexible rod 34. The rear end of the second bidirectional screw 541 located on the rear side is rotatably connected to the front end of the lateral part of the L-shaped fixing plate 4 located on the rear side, and the front end of the second bidirectional screw 541 located on the front side is rotatably connected to the rear end of the lateral part of the L-shaped fixing plate 4 located on the front side. The output shaft of the fourth motor 55 is connected to the second bidirectional screw 541 located on the front side. A second flexible rod 542 is provided between two adjacent second bidirectional screws 541, so that the two adjacent second bidirectional screws 541 are flexibly connected through the second flexible rod 542.

[0077] Multiple rotating shafts 431 and multiple flexible shafts 432 form a rotating frame 43. The rotating shafts 431 located on the rear side are mounted on the front eccentric position of the rotating wheel 42 located on the rear side, and the rotating shafts 431 located on the front side are set on the rear eccentric position of the rotating wheel 42 located on the front side. Flexible shafts 432 are installed between two adjacent rotating shafts 431, and the two adjacent rotating shafts 431 are flexibly connected through the flexible shafts 432. Multiple drive plates 44 are movably mounted on the outer ends of the multiple rotating shafts 431 respectively.

[0078] Multiple rectangular rods 371 and multiple rectangular flexible rods 372 form a guide frame 47. The rear end of the rectangular rod 371 located on the rear side is connected to the front end of the vertical part of the L-shaped fixed plate 4 located on the rear side, and the front end of the rectangular rod 371 located on the front side is connected to the rear end of the vertical part of the L-shaped fixed plate 4 located on the front side. A rectangular flexible rod 372 is installed between two adjacent rectangular rods 371. Multiple rectangular rods 371 are then passed through multiple rectangular slots 451 respectively, and the rectangular rods 371 and the rectangular slots 451 are slidably connected. The rectangular rods 371 and the rectangular slots 451 work together to guide the movement of the functional plate 45.

[0079] In use, firstly, multiple reinforced columns 1001 are installed at equal intervals on the right end of the disassembled upper corrugated beam plate 1002. Then, the H-shaped top plate 1004 is installed onto the reinforced columns 1001 using hexagonal bolts 1041, thereby forming an upper corrugated guardrail structure with the upper corrugated beam plate 1002, multiple reinforced columns 1001, and multiple H-shaped top plates 1004. Then, the base box 1 and other components are moved by the moving wheels, thereby moving the base box 1 to the placement position of the upper corrugated guardrail structure.

[0080] If the required upper guardrail structure is V-shaped, one or more second electric push rods 31 are activated to drive the corresponding functional rods 33 to move and cause the corresponding first flexible rods 34 to deform. This causes the structure formed by multiple functional rods 33 and multiple first flexible rods 34 to deform, thus making the structure V-shaped. At the same time, the second flexible rods 542, flexible shafts 432 and rectangular flexible rods 372 are deformed, thus causing the multi-section bidirectional screws 54 formed by multiple second bidirectional screws 541 and multiple second flexible rods 542, the rotating frame 43 formed by multiple rotating shafts 431 and multiple flexible shafts 432 and the guide frame 47 formed by multiple rectangular rods 371 and multiple rectangular flexible rods 372 to deform.

[0081] Then, by rotating the second motor 21 and the first bidirectional screw 25, multiple first nut seats 23 and multiple second nut seats 26 move outward, thereby causing multiple first arms 22 and multiple second arms 27 to unfold, thereby causing the movable frame 3 and other parts to move to the right, so that there are two F-type clamps 5 between two adjacent encrypted columns 1001.

[0082] Then, the fourth motor 55 drives the rotation of the multi-section bidirectional screw 54 formed by the second bidirectional screw 541 and the second flexible rod 542, thereby causing the two adjacent F-type clamps 5 to move inward. Then, the multiple F-type clamps 5 are used to clamp the multiple densified posts 1001 synchronously. Then, the first electric push rod 24 is used to lift the upper wave guardrail structure. Then, the upper wave guardrail structure is moved to the construction position through four rolling components and the base box 1 and other components, and the multiple densified posts 1001 of the upper wave guardrail structure are aligned with the multiple densified holes respectively.

[0083] Then, the first electric push rod 24 causes the U-shaped frame 2 and other components to move downward, thereby moving the upper wave guardrail structure downward and causing multiple encrypted posts 1001 on the upper wave guardrail structure to be inserted into multiple encrypted holes processed on the road shoulder. Then, milling material is fed into the gap formed between the encrypted posts 1001 and the encrypted holes. At the same time, the third motor 41, two rotating wheels 42, a rotating frame 43 formed by multiple rotating shafts 431 and multiple flexible shafts 432, and multiple drive plates 44 are used. With the assistance of the guide frame 47 formed by multiple rectangular rods 371 and multiple rectangular flexible rods 372 and rectangular grooves 451, multiple functional plates 45 are made to move up and down in a cyclical manner, thereby causing multiple rubber hammers 46 to move up and down. Thus, the multiple rubber hammers 46 moving up and down are used to strike the multiple encrypted posts 1001 inserted into the encrypted holes.

[0084] Then, cement concrete is used to secure the densified posts 1001, thereby completing the installation of the upper wave guardrail structure at the location of the lower wave guardrail structure formed by the lower wave beam 1003 and multiple old posts 1005. This results in the upper wave guardrail structure and the lower wave guardrail structure forming a V-shaped double-layer double-wave guardrail, enabling effective mechanical synchronous construction of the V-shaped double-layer double-wave guardrail. This effectively reduces construction procedures and time, reduces the probability of damage to the lower wave beam 1003, and effectively ensures the construction quality of the double-layer double-wave guardrail.

[0085] A method for constructing a double-layer, double-wave guardrail, using any of the above-mentioned double-layer, double-wave guardrail construction devices, includes the following steps:

[0086] Step 1: Pre-processing. First, install multiple reinforced columns 1001 at equal intervals on the right end of the disassembled upper corrugated beam plate 1002. Then, install the H-shaped top plate 1004 onto the reinforced columns 1001 using hexagonal bolts 1041. This forms an upper corrugated guardrail structure with the upper corrugated beam plate 1002, multiple reinforced columns 1001, and multiple H-shaped top plates 1004. Then, put the milled material generated from the reconstruction into the bottom box 1, so that the milled material generated from the reconstruction falls onto the upper end of the screen plate 14. Then, move the bottom box 1 and other components using four moving wheels, thereby moving the bottom box 1 to the position where the upper corrugated guardrail structure is placed.

[0087] The second step is material loading. The second motor 21 drives the first bidirectional screw 25 to rotate, causing multiple first nut seats 23 and multiple second nut seats 26 to move outwards. This, in turn, causes multiple first supports 22 and multiple second supports 27 to unfold, thereby moving the movable frame 3 and other parts to the right. This allows the upper corrugated beam plate 1002 to pass through the gap between the F-type clamping plate 5 and the rubber hammer head 46 and move to the appropriate position. At this point, there are two F-type clamping plates 5 between each two adjacent reinforced columns 1001. Then, the fourth motor 55 drives the multi-section double... Rotate the screw 54 to move the two adjacent F-type clamps 5 inward, thereby clamping multiple reinforced columns 1001. At this time, the two horizontal parts of the H-type top plate 1004 are respectively located in the grooves 535 of the two adjacent L-type plates 53, and the hexagonal nuts of the hexagonal bolts 1041 are located in the corresponding hexagonal sleeves 533. Then, the first electric push rod 24 moves the U-shaped frame 2 and other components upward, thereby lifting the upper wave guardrail structure. Then, the upper wave guardrail structure is moved to the construction position by four moving wheels and the base box 1 and other components.

[0088] The third step is installation. The first electric push rod 24 moves the U-shaped frame 2 and other components downward, thereby moving the upper wave guardrail structure down and inserting the multiple densified posts 1001 on the upper wave guardrail structure into the multiple densified holes processed on the road shoulder. Then, the first motor 11 drives the worm gear 18 to rotate, thereby rotating the multiple convex wheels 19 and multiple worm wheels 17. The multiple convex wheels 19 and four elastic elements 13 make the screen plate 14 vibrate, thereby allowing the qualified milled material on the screen plate 14 to pass through the screen plate 14 and fall into the multiple inner grooves of the wave plate 16. The multiple worm wheels 17 rotate the multiple spiral rods 15, thereby pushing the milled material in the inner grooves of the wave plate 16 to the opening position of the discharge pipe 12. The discharge pipe 12 then transports the pushed milled material into the gap formed by the densified posts 1001 and the densified holes, thereby completing the filling operation.

[0089] Step 4: Assembly. The rack 534 moves outward via the fourth electric push rod 531, which in turn causes the ring gear 532 and the hexagonal sleeve 533 to rotate in the opposite direction. This causes the hexagonal bolt 1041 to rotate and move outward a certain distance. Then, the push plate 536 moves to the left along the groove 535 using the first telescopic device. This causes the H-shaped top plate 1004 to move to the left and contact the lower corrugated beam plate 1003. Then, the hexagonal bolt 1041 is rotated forward using the fourth electric push rod 531, rack 534, ring gear 532, and hexagonal sleeve 533. This allows the hexagonal bolt 1041 to be re-secured between the H-shaped top plate 1004 and the reinforced column 1001, thus assembling the reinforced column 1001 and the lower corrugated beam plate 1003.

[0090] Step 5: Remove the components. Using the fourth motor 55 and the multi-section bidirectional screw 54, the two adjacent F-type clamping plates 5 are moved outward, thereby releasing the clamping of the encrypted column 1001. At this time, the H-type top plate 1004 and the L-type plate 53 are separated. Then, using the third motor 41, the two rotating wheels 42 and the rotating frame 43 are rotated. With the assistance of multiple drive plates 44, multiple function plates 45 and guide frames 47, multiple rubber hammers 46 are moved up and down in a cyclical motion, thereby striking multiple encrypted columns 1001 respectively. Then, using the third electric push rod 52, the L-type plate 53 is rotated 90°, and then the bottom box 1 and other components are moved, so that the F-type clamping plates 5, L-type plates 53 and other components are moved out of the space between the upper corrugated beam plate 1002 and the lower corrugated beam plate 1003.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

5. A method for constructing a double-layer, double-wave guardrail, using the double-layer, double-wave guardrail construction device as described in claim 4, characterized in that, Includes the following steps: First step, pre-processing: First, install multiple reinforced columns (1001) at equal intervals on the right end of the disassembled upper corrugated beam plate (1002). Then, install the H-shaped top plate (1004) onto the reinforced columns (1001) using hexagonal bolts (1041), so that the upper corrugated beam plate (1002), multiple reinforced columns (1001) and multiple H-shaped top plates (1004) form an upper corrugated guardrail structure. Then, put the milling material generated from the reconstruction into the bottom box (1), so that the milling material generated from the reconstruction falls onto the upper end of the screen plate (14). Then, move the bottom box (1) through four rolling components, so that the bottom box (1) is moved to the position where the upper corrugated guardrail structure is placed. The second step is material loading. The first driving device drives the first bidirectional screw (25) to rotate, thereby causing multiple first nut seats (23) and multiple second nut seats (26) to move outward, which in turn causes multiple first arms (22) and multiple second arms (27) to unfold, thereby causing the movable frame (3) to move to the right, and causing the upper corrugated beam plate (1002) to pass through the gap between the F-type clamp (5) and the rubber hammer (46) and move to the appropriate position. At this time, there are two F-type clamps (5) between each of the two adjacent reinforced columns (1001). Then, the second driving device is used to drive... The multi-section bidirectional screw (54) rotates, causing the two adjacent F-type clamps (5) to move inward, thereby clamping multiple densified columns (1001). At this time, the two transverse parts of the H-type top plate (1004) are respectively located in the grooves (535) of the two adjacent L-type plates (53), and the hexagonal nuts of the hexagonal bolts (1041) are located in the corresponding hexagonal sleeves (533). Then, the U-shaped frame (2) is moved upward by the lifting device, thereby lifting the upper wave guardrail structure. Then, the upper wave guardrail structure is moved to the construction position by four rolling components and the bottom box (1). The third step is installation. The U-shaped frame (2) is moved downward by the lifting device, thereby moving the upper wave guardrail structure down and inserting the multiple densified posts (1001) on the upper wave guardrail structure into the multiple densified holes processed on the road shoulder. Then, the worm gear (18) is driven to rotate by the fourth drive device, thereby rotating the multiple convex wheels (19) and multiple worm wheels (17). The multiple convex wheels (19) and four elastic elements (13) are used to make the screen plate (14) vibrate, thereby making the qualified milling material on the screen plate (14) pass through the screen plate (14) and fall into the multiple inner grooves of the wave plate (16). The multiple worm wheels (17) are used to make the multiple spiral rods (15) rotate, thereby pushing the milling material in the inner groove of the wave plate (16) to the opening position of the discharge pipe (12). The milling material pushed is transported to the gap formed by the densified posts (1001) and the densified holes through the discharge pipe (12), thereby completing the filling operation. Step 4: Assembly. The rack (534) is moved outward by the second telescopic device, which causes the ring gear (532) and the hexagonal sleeve (533) to rotate in the opposite direction, thereby causing the hexagonal bolt (1041) to rotate and move outward a certain distance. Then, the push plate (536) is moved to the left along the groove (535) by the first telescopic device, which causes the H-shaped top plate (1004) to move to the left and contact the lower corrugated beam plate (1003). Then, the hexagonal bolt (1041) is rotated in the forward direction by the second telescopic device, the rack (534), the ring gear (532), and the hexagonal sleeve (533), and then the hexagonal bolt (1041) is used to re-tighten the H-shaped top plate (1004) and the reinforced column (1001), thereby assembling the reinforced column (1001) and the lower corrugated beam plate (1003). Step 5: Remove the F-type clamps (5) that are used together and adjacent to each other are moved outward by the second drive device and the multi-section bidirectional screw (54), thereby releasing the clamps on the encrypted columns (1001). At this time, the H-type top plate (1004) and the L-type plate (53) are separated. Then, the two rotating wheels (42) and the rotating frame (43) are rotated by the third drive device. With the assistance of multiple drive plates (44), multiple function plates (45) and guide frames (47), multiple rubber hammers (46) are moved up and down in a cycle, thereby striking multiple encrypted columns (1001) respectively. Then, the L-type plate (53) is rotated 90° by the third telescopic device. Then, the bottom box (1) is moved, so that the F-type clamps (5) and the L-type plate (53) are moved out of the space between the upper corrugated beam plate (1002) and the lower corrugated beam plate (1003).
