Description

Technical Field

[0001] This utility model relates to the field of cantilever bridge construction machine technology; specifically, this utility model relates to an external formwork suspension rod suitable for a curved beam intelligent cantilever bridge construction machine. Background Technology

[0002] Because in the existing technology, when the hanging basket of the intelligent suspended bridge construction machine for curved beams is suspended using fine steel threads as hangers, the fine steel threads will deform and suffer irreversible damage under the action of lateral stress. Therefore, the existing technology uses a combination of slings and hangers as the outer formwork hangers of the hanging basket as the whole.

[0003] For example, utility model patent CN220908187U provides a cantilever bridge construction machine external formwork suspension rod device, including a suspension rod body, a hanging leg, a jack, a sling, and a bottom crossbeam. The top of the suspension rod body passes through a first nut, a first steel pad, a jack, a second steel pad, and a second nut in sequence. The bottom of the suspension rod body is installed in the mounting hole of the hanging leg crossbeam through a third nut and a third steel pad. The hanging leg crossbeam is fixedly connected to the hanging leg. The bottom of the suspension rod body is connected to the top of the sling through a steel pad and a first pin. The bottom of the sling is connected to the bottom crossbeam through a second pin and a conversion frame. This utility model uses a combination of suspension rod and sling, and controls the height of the suspension rod with a hydraulic cylinder, which can accurately and quickly adjust the height of the sling. This allows for convenient and quick adjustment of the bottom formwork, and the conversion frame ensures that the external suspension rod is subjected to vertical force, guaranteeing safe and controllable force on the external suspension rod and avoiding the safety risks caused by suspension rod deformation.

[0004] However, the aforementioned existing technology directly uses slings to suspend the bottom beam. Although slings can better cope with lateral stress than rods, they are not as rigid and stable as rods, which may pose certain safety hazards. Utility Model Content

[0005] In view of this, the present invention provides an external formwork hanger suitable for a curved beam intelligent cantilever bridge construction machine, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0006] To achieve the aforementioned objectives, this utility model provides an external formwork suspension rod suitable for a curved beam intelligent cantilever bridge construction machine, comprising a suspension rod, a sling connected to the bottom of the suspension rod, and a conversion frame connected to the bottom of the sling. An anti-fall rod assembly is connected between the bottom end of the suspension rod and the top end of the rotating frame. The sling is fitted onto the anti-fall rod assembly. The anti-fall rod assembly includes an upper rod body, a lower rod body, a locking hook, a locking groove, and a locking spring. The top end of the upper rod body is connected to the bottom end of the suspension rod, and the bottom end of the lower rod body is connected to the top end of the rotating frame.

The locking hook is inserted into the upper rod, with the top end of the locking hook extending from the side of the upper rod and the bottom end of the locking hook abutting against the inner wall of the lower rod. The bottom end of the locking hook is located below the locking groove. The locking spring is located between the upper rod and the locking rod to provide a force for the locking rod to move radially outward along the upper rod. The two vertical sides of the sling press the top end of the locking hook inward from the side.

[0007] In the aforementioned external formwork suspension rod of an intelligent suspended bridge construction machine for curved beams, optionally, the ball hinge structure includes a ball seat, a ball groove, and a ball.

[0011] In the aforementioned external formwork suspension rod of an intelligent cantilever bridge construction machine for curved beams, optionally, the lower rod body is provided with pre-tensioning springs at both ends that connect the upper rod body and the lower rod body.

[0012] This utility model relates to an external formwork suspension rod for a curved beam intelligent cantilever bridge construction machine. Based on the suspension rod and sling, an anti-fall rod assembly is set up. The anti-fall rod assembly is connected to the suspension rod and the conversion frame through a ball hinge structure. It can relieve lateral stress through its own swing and extension.

Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1 to 3As shown, this utility model provides an outer formwork suspension rod 1 suitable for a curved beam intelligent cantilever bridge construction machine, including a suspension rod 1, a sling 2 connected to the bottom of the suspension rod 1, and a conversion frame 3 connected to the bottom of the sling 2. A fall arrestor assembly is connected between the bottom end of the suspension rod 1 and the top end of the swivel frame. The sling 2 is fitted onto the fall arrestor assembly. The fall arrestor assembly includes an upper rod body 4, a lower rod body 5, a locking hook 6, a locking groove 7, and a locking spring 8. The top end of the upper rod body 4 and the bottom end of the suspension rod 1, and the bottom end of the lower rod body 5 and the top end of the swivel frame, are connected by ball joints. The hinge structure connects the upper rod 4, with the bottom end of the upper rod 4 inserted into the lower rod 5 from the top end. The locking groove 7 is located on the side of the lower rod 5. The locking hook 6 passes through the upper rod 4, with the top end of the locking hook 6 extending from the side of the upper rod 4 and the bottom end of the locking hook 6 abutting against the inner wall of the lower rod 5. The bottom end of the locking hook 6 is located below the locking groove 7. The locking spring 8 is located between the upper rod 4 and the locking rod, and is used to provide the locking rod with a force that moves radially outward along the upper rod 4. The two vertical sides of the sling 2 press the top end of the locking hook 6 inward from the side.

[0020] By setting up the anti-fall bar assembly, when the end beam of the sling 2 becomes loose, the sling 2 will lose pressure on the locking hook 6. At the same time, the upper rod 4 and the lower rod 5 will slide relative to each other, and the locking hook 6 will move upward within the lower rod 5. Meanwhile, the locking spring 8 will always maintain an outward force on the locking hook 6, so that after passing through the locking groove 7, the locking hook 6 can be inserted into the locking groove 7 under the action of the locking spring 8, thereby limiting the upper rod 4 and the lower rod 5 and achieving the anti-fall effect.

[0021] The upper and lower ends of the fall arrestor assembly are connected to the hanger 1 and the conversion frame 3 respectively by a ball hinge structure. This allows the fall arrestor assembly to swing and extend accordingly when the bottom of the beam is slightly tilted or deformed, so as to better relieve the lateral stress on the hanger 1 caused by the slight tilt or deformation of the bottom of the beam and avoid deformation of the hanger 1.

[0022] Specifically, the ball hinge structure includes a ball seat 9, a ball groove 10, and a ball 11. The two ball seats 9 are fixedly installed at the bottom end of the rod 1 and the top end of the conversion frame 3, respectively. The opposite surfaces of the two ball seats 9 are provided with ball grooves 10. The two balls 11 are rotatably installed in the two ball grooves 10, and the top end of the upper rod 4 and the bottom end of the lower rod 5 are fixedly connected to the two balls 11, respectively.

[0023] Furthermore, the upper ball seat 9 is configured as an inverted "U" shaped structure, with a perforation 12 at its top for the sling 2 to pass through. The inner wall of the side of the perforation 12 supporting the sling 2 is a plane adapted to the sling 2. This configuration allows the sling 2 to be stably supported, preventing it from twisting and improving its service life and safety.

[0024] Specifically, the bottom of the lifting rod 1 is provided with a U-shaped connecting rod 13 with its opening facing downwards, and the two ends of the bottom of the connecting rod 13 are respectively fixed to the front and rear sides of the ball seat 9 located above. The through hole 12 is located between the connecting rod 13 and the ball seat 9 located above. The top of the sling 2 is effectively confined within the through hole 12, which can further improve stability and safety.

[0025] Furthermore, a sleeve plate 14 is fixedly provided at the top of the hook 6, which can be fitted over the outside of the sling 2. By providing the sleeve plate 14, the top of the hook 6 is effectively connected to the sling 2. When the sling 2 is under tension, pressure is always applied to the hook 6 through the sleeve plate 14 to ensure that the hook 6 will not malfunction. When the sling 2 breaks or loosens, the pressure on the hook 6 will be relieved.

[0026] The lower rod 5 is internally equipped with preload springs 15 that connect the upper rod 4 and the lower rod 5 at both ends. When the bottom beam tilts or moves slightly, the preload springs 15 provide buffering and damping forces during the extension and retraction of the fall arrestor assembly to further improve safety.

[0027] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
