Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, and more specifically to a hoisting balancing device for moving super-large PC components and superimposed plates. Background Art

[0002] With the rapid development of the construction industry, precast concrete (PC) components and composite panels have been widely used in the construction field due to their high efficiency, environmental protection, stable quality and other advantages. Especially in large public buildings, bridges, tunnels and other projects, their use is becoming more and more common. However, there are many challenges in the lifting and moving of these large components.

[0003] Due to its large size and heavy weight, it is easy to shake or tilt during the lifting process, which not only affects the construction efficiency but also may cause safety accidents.

[0004] Traditional lifting equipment can only provide simple lifting functions, but cannot adjust the balance of components in real time during the lifting process. Different PC components and laminated boards may differ in size, weight and shape, and traditional lifting equipment often has difficulty adapting to these differences. Utility Model Content

[0005] In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides a hoisting balancing device for moving super-large PC components and laminated plates. The hoisting balancing device can adjust the balance state of the component in real time during the hoisting process to ensure the stability and safety of the hoisting process. It can adapt to the hoisting requirements of PC components and laminated plates of different sizes, weights and shapes. It reduces manual operations and improves hoisting efficiency and accuracy. It solves the stability, accuracy and efficiency problems faced by traditional hoisting equipment when hoisting large components.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A hoisting and balancing device for moving super-large PC components and composite plates comprises a balancing frame, ear plates, rope pulleys and steel wire ropes. The balancing frame adopts a rectangular frame structure. Four groups of ear plates are symmetrically arranged on the long sides of the balancing frame. Multiple groups of rope pulleys are symmetrically arranged on the two long sides of the balancing frame. Corner rope pulleys are arranged on the four corners of the bottom of the balancing frame. The steel wire rope passes through all the rope pulleys and the corner rope pulleys. A lifting and hoisting assembly is hung on the steel wire ropes between adjacent rope pulleys and between the rope pulleys and the corner rope pulleys.

[0008] The lifting and hoisting assembly includes a pulley, a locking card, a lifting chain and an anti-drop hook. A connecting hook is provided at the bottom of the pulley, the connecting hook is connected to the locking card, the top of the lifting chain is connected to the locking card, and the bottom of the lifting chain is connected to the anti-drop hook.

[0009] The pulley adopts a self-locking positioning pulley device.

[0010] The pulley is slidably arranged on the steel wire rope.

[0011] The four corners of the balancing frame are provided with mounting seats, and the bottom of the mounting seats is provided with moving wheels.

[0012] The rope passing wheel is provided with a self-locking structure.

[0013] Three groups of rope pulleys are arranged on the long sides of the balancing frame.

[0014] The turning angle is connected to the balance frame through a rotating shaft through the top of the rope pulley.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The setting of ear plates on the balance frame facilitates the connection of lifting devices during lifting, so as to lift the balance frame and the PC components and composite plates below; the setting of rope pulleys and corner rope pulleys realizes the overall series connection through wire ropes, and realizes multi-point lifting. Compared with the single lifting point structure, it shares the force on the lifting point, realizes the balance of lifting force, ensures the balance and reliability of lifting of PC components and composite plates, and prevents damage. Multiple lifting and hoisting components are set between the rope pulleys, so that the load is shared by multiple points, the fatigue damage of the lifting rope is reduced, and the safety of the lifting construction is ensured; due to the different lifting point positions of different lifting and hoisting components on the balance frame, and the different uniformity of the center of gravity distribution of PC components and composite plates, the lifting and hoisting components move along the rigid rope under the action of the rope pulley and corner rope pulley, thereby adjusting the height of each lifting point, and finally achieving self-balancing.

[0017] It is convenient for lifting and positioning, improves the accuracy of positioning, greatly reduces the effective height required for component lifting, speeds up lifting efficiency, and ensures construction progress. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figures 1 to 4 As shown, a lifting and balancing device for moving super-large PC components and composite plates includes a balancing frame 1, an ear plate 2, a rope pulley 3 and a wire rope 5. The balancing frame 1 adopts a rectangular frame structure. Four groups of ear plates 2 are symmetrically arranged on the long sides of the balancing frame 1. The ear plate 2 is used to connect the lifting rope. Multiple groups of rope pulleys 3 are symmetrically arranged on the two long sides of the balancing frame 1. Corner rope pulleys 4 are arranged at the four corners of the bottom of the balancing frame 1. The wire rope 5 passes through all the rope pulleys 3 and the corner rope pulleys 4. The wire rope 5 is arranged around the balancing frame 1 between adjacent rope pulleys 3 and between the rope pulley 3 and the corner rope pulley 4. A lifting and hoisting assembly 6 is hung on the wire rope 5. The bottom of each lifting assembly 6 is connected to the oversized PC component or laminated plate to be lifted, and the balance frame 1 is lifted. Due to the different positions of the lifting points and the different uniformity of the center of gravity distribution of the components, the heights of the lifting assemblies 6 at different points are different during lifting. Under the action of the wire rope 5, each lifting assembly cooperates with each other, moves on the wire rope 5, adjusts the height of each lower lifting part, and finally achieves self-balancing. Ensure the balance and reliability of the lifting of the component or laminated plate.

[0026] Preferably, the lifting and hoisting assembly 6 includes a pulley 7, a locking card 9, a lifting chain 10 and an anti-drop hook 11.

The slide 7 is slidably arranged on the wire rope 5, and the anti-drop hook 11 is used to connect with the object to be lifted.

[0027] Preferably, the pulley 7 adopts a self-locking pulley device. During lifting, when each lifting and hoisting assembly moves on the wire rope 5 and achieves self-balancing, the pulley 7 is locked to prevent it from deflecting during the lifting process.

[0028] Preferably, the pulley 7 is slidably arranged on the steel wire rope 5 .

[0029] Preferably, mounting seats 12 are provided at the four corners of the balancing frame 1, and moving wheels 13 are provided at the bottom of the mounting seats 12. The provision of the moving wheels 13 facilitates the balancing frame 1 to move on the ground and change the construction position.

[0030] Preferably, a self-locking structure is provided on the rope pulley 3. After each hoisting assembly 6 achieves self-balancing, the wire rope 5 is tightened, and the height of each hoisting assembly 6 during hoisting is determined. The self-locking of the rope pulley 3 locks the wire rope 5, thereby ensuring the stability of the hoisting process.

[0031] Preferably, three groups of rope pulleys 3 are arranged on the long sides of the balancing frame 1 .

[0032] Preferably, the top of the corner rope pulley 4 is connected to the balance frame 1 through a rotating shaft. The corner rope pulley 4 can rotate in the horizontal direction to meet the movement of the wire rope 5.

[0033] The circumference of the wire rope 5 is greater than the circumference of the balance frame 1, the lifting device is connected to the ear plate 2, and the lifting and hoisting assembly 6 is connected to the component or the composite plate for lifting. Under the action of the wire rope 5, each lifting and hoisting assembly cooperates with each other, moves on the wire rope 5, adjusts the height of each lower lifting part, and finally achieves self-balancing. After achieving balance, the rope wheel 3 and the pulley 7 are locked to ensure the stability of lifting.
