Description

Technical Field

[0001] The present invention relates to the field of bridge engineering equipment, and in particular to a rapid casting and forming device and a forming method for a bridge crash wall. Background Art

[0002] Bridge crash barriers play a vital role in bridge construction, effectively preventing vehicles from running off the bridge deck and ensuring driving safety. With the continuous development of bridge construction, higher requirements are being placed on the construction quality and efficiency of bridge crash barriers. However, existing bridge crash barrier casting technology has many shortcomings.

[0003] Existing methods for conveying and distributing pouring materials are relatively simple. They typically rely on simple pipes, lacking effective diversion devices. This results in uneven distribution of pouring material within the formwork, necessitating multiple adjustments and additional pours, significantly extending the pouring time. For example, during the pouring of crash barriers on some large bridges, the inability to quickly and evenly fill the formwork with material can cause the entire pouring process to take hours or even days, severely impacting construction progress.

[0004] Vibration is a key step in ensuring pouring quality, but existing vibrating equipment and methods have limitations. Traditional vibrating equipment is often only able to vibrate locally, failing to achieve a comprehensive and uniform vibration effect. Furthermore, the vibration process is prone to uneven vibration, resulting in insufficient density of the poured material in some areas, affecting the overall strength and durability of the bridge's crash barrier. Furthermore, the operation of vibrating equipment is complex, requiring frequent manual adjustments to position and force, which increases the labor intensity and time costs of construction workers.

[0005] During formwork installation, existing technologies lack effective positioning and fixing measures. Formwork is prone to displacement and deviation, resulting in inaccurate dimensions and uneven surfaces after pouring the bridge crash barrier. For example, deviations in the installation angle and position of the formwork can cause the crash barrier to tilt or twist, affecting both its aesthetics and its crashworthiness.

[0006] Due to imperfections in the pouring and vibration processes, existing technologies struggle to ensure uniform density of the poured material throughout the formwork. Honeycombing and pockmarked surfaces may appear in some areas, reducing the strength and impermeability of the bridge crash barrier. These defects can cause cracks and spalling over long periods of use, shortening the service life of the bridge crash barrier.

[0007] Different bridge designs have varying requirements for crash barriers, and consequently, for height and angle. However, existing casting equipment often lacks flexible height and angle adjustment capabilities. The construction of crash barriers for bridges of varying specifications requires the replacement of different equipment or complex modifications, increasing construction costs and time.

[0008] In summary, the existing bridge crash wall casting and molding technology has many shortcomings in construction efficiency, molding quality, equipment flexibility and demoulding. Therefore, a bridge crash wall rapid casting and molding device and molding method are proposed. Summary of the Invention

An installation shaft is installed under the annular ring, and a template flipping mixing wheel is provided on the installation shaft.

[0018] A method for rapidly casting and forming a bridge crash barrier comprises the following steps: Step 1, installing and fixing the device: installing a bridge mold pier frame at a suitable bridge construction location and ensuring that it is stable and firm; installing a casting and forming mold above the bridge mold pier frame, and embedding a steel bar column between the bridge mold pier frame and the casting and forming mold to play a reinforcing role; limiting the casting and forming mold by a limiting rod and a limiting plate, so that the limiting rod is located at the top of the bridge mold pier frame to ensure the accurate position of the casting and forming mold; Step 2: Component connection and debugging: Install the magnetic adsorption base in the center end of the casting mold and connect the casting delivery pipe; install the molding casting pipe on the top pipe of the casting delivery pipe, nest the casting forming diverter plate in the middle section, and nest the casting forming plate at the bottom end. At the same time, install the connection reinforcement plate and connecting bolts to ensure that all components are tightly connected; Check whether the casting and forming diversion pipe on the casting and forming diversion plate is accurately embedded in the casting and forming uniform casting hole on the top plate of the casting and forming plate; install the vibration motor and its related components, including the vibrating vibration frame, spring rotation frame, elastic buffer support pad, rotation frame fixed anchor point, vibrating buffer spring, spring fixing rivet, casting and vibrating vibration linkage ring and scraping partition, and debug whether their operation is normal; Install the mold adjustment arm hydraulic arm, mold adjustment arm hydraulic rotation shaft, linkage mold adjustment arm, bridge formwork pier, linkage mold adjustment arm movable frame, eccentric clamping fixed rod, protective soft rubber pad, linkage balance beam, magnetic coupling linkage rod, forming plate rib beam and forming plate angle brace, and debug; install the rotary demoulding cam, vibrating eccentric hammer, swing U-shaped groove, annular ring, installation shaft and template flip mixing wheel, and check the connection and fit between each component; Step 2, concrete delivery: Concrete is delivered to the casting delivery pipe through the forming casting pipe; the concrete reaches the casting forming diversion plate through the casting delivery pipe, and after being diverted by the casting forming diversion pipe, it flows evenly into the inner cavity of the forming template from the casting forming uniform casting holes on the casting forming plate; Step 3, vibrating and leveling: Start the vibration motor to drive the vibrating frame to vibrate, and transmit the vibration to the pouring and vibrating vibration linkage ring through the spring rotation frame and the vibration buffer spring component; the pouring and vibrating vibration linkage ring vibrates on the annular ring to vibrate the concrete in the inner cavity of the forming template to make the concrete more dense; the leveling partition scrapes the concrete surface with the movement of the pouring and vibrating vibration linkage ring to ensure the concrete surface is flat; Step 4: Mold adjustment and forming: The mold adjustment arm adjusts the hydraulic arm and the mold adjustment arm adjusts the hydraulic rotation axis to control the angle and position of the linkage mold adjustment arm; the linkage mold adjustment arm drives the bridge formwork pier frame and the linkage mold adjustment arm movable frame components to fine-tune the casting and forming process; Step 5, demoulding operation: start the magnetic coupling linkage rod to drive the rotary demoulding cam to rotate; the rotary demoulding cam drives the vibrating eccentric hammer to swing, and the vibrating eccentric hammer moves in the swing U-shaped groove to generate vibration to assist demoulding; the template flip mixing wheel rotates on the installation shaft to help separate the casting mold from the formed anti-collision wall, completing the demoulding process; Step 6: Clean the device and remove residual concrete and debris; check the wear of each component, replace and repair damaged components, and prepare for the next pouring.

[0019] The beneficial effects of this invention are as follows: The bridge mold pier frame serves as the foundational support structure for the entire device, providing stable and reliable support for the pouring operation, ensuring that the device does not shake or shift during construction, thus ensuring construction safety and stability. Furthermore, the steel columns embedded between the bridge mold pier frame and the pouring mold further enhance the overall structural strength of the device, improving its load-bearing capacity and adapting to pouring operations of varying sizes and weights.

[0020] The setting of the limiting rod and the limiting plate at the front end of the casting and forming mold of the present invention enables the casting and forming mold to be accurately installed on the bridge mold pier, ensuring the accuracy of the template installation position, thereby improving the forming accuracy of the bridge crash barrier and reducing the forming quality problems caused by template installation deviation.

[0021] The present invention utilizes a molded pouring pipe, a pouring delivery pipe, and a molded diverter plate to quickly and efficiently deliver pouring material to the inner cavity of the molded template. The molded diverter plate rationally diverts the pouring material, and then achieves uniform pouring through the molded uniform pouring holes, significantly improving pouring efficiency and shortening the construction period.

[0022] The vibrating motor in this invention drives the vibrating frame to generate vibrations. Through the cushioning and adjustment of the spring crossbar, elastic buffer support pad, and vibration buffer spring components, the vibrations are effectively transmitted to the casting material, fully compacting the material while preventing damage to the device caused by excessive vibration. The leveling baffle, under the action of vibration, leveled the casting material, further ensuring uniform distribution of the casting material and improving the quality of the bridge crash barrier.

[0023] The casting and forming lifting columns can flexibly adjust the height of the casting plate according to the casting requirements of different bridge crash barriers. The hydraulic adjustment arm drives the linkage adjustment arm through the hydraulic adjustment shaft, which can accurately adjust the position and angle of the template. This makes the device suitable for casting bridge crash barriers of various shapes and sizes, improving the versatility and adaptability of the device.

[0024] The eccentric clamping fixing rod of the present invention is combined with a protective soft rubber pad to ensure the clamping force when clamping the formwork and prevent damage to the formwork, thereby ensuring that the formwork remains stable during the pouring and vibration process and extending the service life of the formwork. The rotating demoulding cam drives the vibrating eccentric hammer to generate vibration, which is transmitted to the casting and forming disk by swinging the U-shaped groove and the annular ring, effectively loosening the connection between the formed bridge crash barrier and the formwork, reducing the difficulty of demoulding. The formwork flipping mixing wheel assists the flipping of the formwork, making the demoulding process smoother, reducing the difficulty and labor intensity of manual operation, and improving the demoulding efficiency. The structural design of each component of the device is reasonable. After demoulding is completed, the casting and forming mold and the casting conveying pipe components can be easily cleaned, and the residual casting material can be removed in time. At the same time, the connection method between the various components is convenient for disassembly and assembly, which is conducive to regular inspection and maintenance of the device, extending the service life of the device and reducing the cost of use.

[0033] See also Figure 5 and Figure 6The bridge formwork pier frame 29 is respectively equipped with a linkage mold adjustment arm movable frame 30 and an eccentric clamping fixing rod 31 at both ends.

[0035] The working principle of the rapid casting and forming device for bridge crash barriers: First, the bridge mold pier frame 1 is placed in a suitable position as the basic supporting structure of the entire device. The casting and forming mold 2 is installed above the bridge mold pier frame 1. By embedding the steel bar column 3 between the bridge mold pier frame 1 and the casting and forming mold 2, the stability and structural strength of the connection between the two are enhanced. The limiting rod 5 installed at the front end of the casting and forming mold 2 is located at the top of the bridge mold pier frame 1, and the limiting plate 6 is fixed on the limiting rod 5, which is used to accurately limit the position of the casting and forming mold 2, ensure the accuracy and stability of its installation, and provide a reliable foundation for subsequent casting operations.

[0036] When the pouring operation begins, the pouring material enters the pouring delivery pipe 8 through the molding pouring pipe 9. The pouring delivery pipe 8 is fixed in the center end of the casting and molding mold 2 by the magnetic adsorption base 7 to ensure the stability of the conveying process. When the pouring material is transported to the pouring molding diverter plate 10 at the middle section of the pouring delivery pipe 8, the pouring molding diverter plate 10 diverts the pouring material. The pouring molding diverter pipe 11 arranged thereon guides the diverted pouring material to the pouring molding disk 12, and the pouring molding uniform pouring hole 25 on the top plate of the pouring molding disk 12 matches the pouring molding diverter pipe 11, so that the pouring material can flow evenly into the inner cavity 4 of the molding template, creating good conditions for the molding of the bridge crash barrier.

[0037] During the pouring process, the vibration motor 15 starts, driving the vibrating frame 16 to vibrate. The spring cross frame 17, elastic buffer support pad 18, and vibration buffer spring 20 above the vibrating frame 16 work together. The spring cross frame 17 is positioned by the cross frame fixed anchor point 19, and the vibration buffer spring 20 is fixed between the two rods of the spring cross frame 17 by the spring fixing rivet 21. These components play the role of buffering and adjusting the vibration amplitude to prevent excessive vibration from damaging the device, while ensuring that the vibration can be effectively transmitted to the casting material. The casting vibration linkage ring 22 is connected to the vibrating frame 16 and transmits the vibration to the scraping baffle 23. Under the action of vibration, the scraping baffle 23 scrapes the casting material flowing into the inner cavity 4 of the forming template to make the casting material more evenly distributed and improve the molding quality.

[0038] The casting and forming lifting column 24 between the casting and forming diverter plate 10 and the casting and forming plate 12 can adjust the height of the casting and forming plate 12 according to the actual casting needs to adapt to the casting requirements of bridge crash barriers of different specifications. The mold adjustment arm adjustment hydraulic arm 26 drives the linkage mold adjustment arm 28 to move through the mold adjustment arm adjustment hydraulic rotating shaft 27, and the linkage mold adjustment arm 28 is connected to the bridge formwork pier frame 29. The linkage mold adjustment arm movable frame 30 and the eccentric clamping fixing rod 31 at the head and tail ends of the bridge formwork pier frame 29 work together, and the protective soft rubber pad 32 in the U groove of the eccentric clamping fixing rod 31 can protect the formwork during the clamping process. Through the coordinated movement of these components, the position and angle of the formwork can be precisely adjusted to ensure that the cast bridge crash wall meets the design requirements.

[0039] See also Figure 7 A rotating demolding cam 37 is embedded beneath the magnetic coupling linkage rod 34 between the linkage balance beams 33. A vibrating eccentric hammer 38 is attached to the rotary demolding cam 37. When demolding is required, the rotary demolding cam 37 rotates, driving the vibrating eccentric hammer 38. The swinging U-shaped groove 39 within the vibrating eccentric hammer 38 connects to the annular ring 40 on the outer surface of the casting plate 12, transmitting vibrations to the casting plate 12 and assisting in the demolding process. Simultaneously, a template flipping and mixing wheel 42 mounted on the shaft 41 assists in flipping the template during demolding, making the demolding operation smoother.

[0041] During use of the present invention, the bridge mold pier frame 1 is installed at a predetermined bridge construction position to ensure that it is stable and firm, providing a stable support foundation for the entire device.

[0042] Formwork Installation: Install the casting mold 2 above the bridge mold pier 1. Insert steel bars 3 between the bridge mold pier 1 and the casting mold 2 to enhance the stability of the overall structure. Simultaneously, place the limit rod 5 on top of the bridge mold pier 1 and secure the limit plate 6. Precisely adjust the position of the casting mold 2 to ensure it is properly installed.

[0043] Pipeline connection: Install the pouring conveying pipe 8 in the center end of the pouring molding mold 2 through the magnetic adsorption base 7 to ensure a firm connection. Then connect the molding pouring pipe 9 to the top pipe of the pouring conveying pipe 8 to prepare for the delivery of the pouring material.

[0044] Component inspection: Check whether the vibration motor 15 and the mold adjustment arm hydraulic arm 26 power components are operating normally, whether all connection parts are tightened, and ensure that all components of the device are in good working condition.

[0045] Height adjustment: according to the height requirement of the bridge crash wall to be cast, the casting and forming lifting column 24 is started to adjust the height of the casting and forming plate 12 to reach a suitable casting position.

[0046] Fine-tuning the angle and position: Operate the mold adjustment arm 26 to adjust the hydraulic arm, which in turn drives the linkage mold adjustment arm 28 through the hydraulic rotation axis 27. The bridge formwork pier 29, linkage mold adjustment arm movable frame 30, and eccentric clamping rod 31, connected to the linkage mold adjustment arm 28, work together to precisely adjust the angle and position of the casting mold 2. A protective soft rubber pad 32 in the U-shaped groove of the eccentric clamping rod 31 protects the formwork from damage while ensuring appropriate clamping force.

[0047] Material transportation: The stirred casting material is fed into the casting delivery pipe 8 through the molding casting pipe 9. The casting material flows downward along the casting delivery pipe 8 and reaches the casting molding diverter plate 10 in the middle section.

[0048] Diversion and uniform pouring: The casting diverter plate 10 diverts the casting material and guides the material to the casting plate 12 through the casting diverter pipe 11. The casting uniform pouring holes 25 on the top plate of the casting plate 12 allow the casting material to flow evenly into the inner cavity 4 of the forming template, starting the pouring of the bridge crash wall.

[0049] Start vibration: During the pouring process, start the vibration motor 15 at the same time. The vibration motor 15 drives the vibration frame 16 to vibrate, and the vibration is buffered and adjusted by the spring rotation frame 17 and the vibration buffer spring 20 to avoid excessive vibration and damage to the device.

[0050] Scraping operation: The casting and vibrating linkage ring 22 transmits the vibration to the scraping baffle 23. Under the action of vibration, the scraping baffle 23 scrapes the casting material flowing into the inner cavity 4 of the forming template, so that the casting material is more evenly distributed in the inner cavity 4 of the forming template, thereby improving the forming quality of the bridge crash barrier.

[0051] Vibration-Assisted Demolding: When the cast material reaches a certain set strength, demolding is required. The rotary demolding cam 37 begins to rotate, driving the vibrating eccentric hammer 38. The swinging U-shaped groove 39 within the vibrating eccentric hammer 38 connects to the annular ring 40 on the outer surface of the casting plate 12, transmitting vibrations to the casting plate 12, helping to loosen the connection between the formed bridge crash barrier and the formwork.

[0052] Template flipping: The template flipping mixing wheel 42 on the mounting shaft 41 assists in flipping the template during demolding, allowing the formed bridge crash barrier to be smoothly separated from the template. At the same time, the linked mold adjustment arm 28 can appropriately adjust the template position to facilitate the demolding operation.

[0053] Cleaning the template: After demoulding is completed, clean the casting material remaining in the casting mold 2 and the casting delivery pipe 8 in time to keep the device clean.

[0054] Component inspection and maintenance: Inspect all components of the device, such as the spring rotation frame 17 and the vibration buffer spring 20 for damage, and replace or repair damaged components in a timely manner. At the same time, lubricate the moving parts of the device to prepare for the next pouring operation.
