Description

Technical Field

[0001] This utility model belongs to the field of hoisting devices and relates to a large-span steel structure hoisting beam device. Background Technology

[0002] A beam lifting device is a crucial piece of equipment in building construction, especially in the construction of large-span steel structures. It is primarily used to lift large steel structural components from one location to a designated installation position. In the construction of large-span steel structures, such as large stadiums and bridges, many steel structural components are enormous in size and weight.

[0003] In terms of balanced hoisting, most devices rely on a single hoisting rope connection, making it difficult to evenly distribute the hoisting force to the hoisted components. This can lead to excessive local stress when hoisting large-span steel structures, causing deformation or even breakage of the hoisting beams, which seriously affects construction safety and progress. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a safe hoisting device for large-span steel structure beams.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A large-span steel structure lifting beam device, characterized in that it includes a metal hook component, the upper end of which is connected to a main composite lifting rope, and a crane is connected to the main composite lifting rope. A balancing lifting truss is installed at the lower end of the metal hook component, and a pair of secondary composite lifting ropes are fixedly connected to the lower end of the balancing lifting truss. The two secondary composite lifting ropes are equidistant from each other. Symmetrical hooks for securing objects are fixedly connected to the lower ends of the secondary composite lifting ropes on both the front and rear sides. The lower end of the hook for securing objects on the front side is provided with an inner hollow layer self-rotating rod, and the lower end of the hook for securing objects on the rear side is provided with an inner locking self-rotating rod. An electric rotating shaft connector is installed at the lower end of the hook for securing objects, and the two electric rotating shaft connectors are respectively connected to the corresponding inner hollow layer self-rotating rod or inner locking self-rotating rod.

[0007] In the aforementioned large-span steel structure lifting beam device, the two corresponding inner hollow layer self-rotating rods and inner locking self-rotating rods are connected to each other, and the steel structure components being lifted are clamped between multiple symmetrical hooks.

[0008] In the aforementioned large-span steel structure lifting beam device, the lower inner wall of the symmetrical hook for securing the object is fixedly connected with an anti-slip inner pad layer, which is in contact with the steel structure being lifted.

[0009] In the aforementioned large-span steel structure lifting beam device, the front and rear ends of the balance lifting truss are symmetrically fixed with reinforcing inner ribs, and the upper and lower inner walls of the inner hollow layer self-rotating rod are symmetrically provided with alignment grooves.

[0010] In the aforementioned large-span steel structure hanging beam device, grooves are symmetrically provided at both the upper and lower ends of the inner locking self-rotating rod, and an electric push rod is fixedly connected to the lower inner wall of the groove.

[0011] In the aforementioned large-span steel structure suspension beam device, the output end of the electric push rod is connected to an abutment limiting member, and the upper end of the abutment limiting member is fixedly connected to an outwardly protruding stabilizing rubber particle.

[0012] In the aforementioned large-span steel structure hanging beam device, the abutting and limiting member extends into the corresponding alignment groove opening, and the abutting and limiting member contacts the inner sidewall of the alignment groove opening.

[0013] Compared with existing technologies, this large-span steel structure lifting beam device uses four sets of symmetrical hooks below the balancing lifting truss to limit the lifting of the steel structure components on the outside. During the lifting process, the inner hollow layer self-rotating rod and the inner locking self-rotating rod rotate to the bottom of the steel structure component through electric rotating shaft connectors, and achieve seamless connection between the two through a precisely designed locking structure. This design can not only effectively share the pressure during the lifting process, but also significantly improve the lifting stability of the symmetrical hooks. In addition, when the steel structure component tilts due to external factors, the inner hollow layer self-rotating rod and the inner locking self-rotating rod can timely share and support the tilting pressure through their interlocking structure, thereby preventing the steel structure component from falling accidentally at high altitudes, greatly improving the safety and reliability of long-distance lifting.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 As shown in Figure 4, this large-span steel structure suspension beam device includes a metal hook component 1. The upper end of the metal hook component 1 is connected to a main composite suspension rope 16, and a crane is connected to the main composite suspension rope 16. A balancing hoisting truss 2 is installed at the lower end of the metal hook component 1. A pair of secondary composite suspension ropes 3 are fixedly connected to the lower end of the balancing hoisting truss 2, and the two secondary composite suspension ropes 3 are equidistant from each other. Symmetrical hooks 4 are fixedly connected to the lower ends of the secondary composite suspension ropes 3 on both the front and rear sides. The lower end of the hook 4 on the front side is provided with an inner hollow layer self-rotating rod 7, and the lower end of the hook 4 on the rear side is provided with an inner locking self-rotating rod 8. An electric rotating shaft connector 6 is installed at the lower end of the hook 4. The two electric rotating shaft connectors 6 are respectively connected to the corresponding inner hollow layer self-rotating rod 7 or inner locking self-rotating rod 8.

[0023] The two inner hollow layer self-rotating rods 7 and the inner locking self-rotating rods 8, which are corresponding to each other, are connected to each other, and the steel structure hoisted component 14 is clamped between the multiple symmetrical hooks 4.

[0024] The lower inner wall of the symmetrical hook 4 is fixedly connected with an anti-slip inner pad 5, which is in contact with the steel structure being hoisted 14.

[0025] The front and rear ends of the balance hoisting truss 2 are symmetrically fixed with reinforcing inner ribs 15, and the upper and lower inner walls of the inner hollow layer self-rotating rod 7 are symmetrically provided with alignment groove slots 13.

[0026] The inner locking self-rotating rod 8 has symmetrical grooves 9 at its upper and lower ends, and an electric push rod 10 is fixedly connected to the lower inner wall of the groove 9.

[0027] The output end of the electric push rod 10 is connected to an abutment limiting member 11, which extends into the corresponding alignment groove opening 13, and the abutment limiting member 11 is in contact with the inner sidewall of the alignment groove opening 13.

[0028] In this scheme, the crane uses four sets of symmetrical hooks 4 below the balancing hoisting truss 2 to limit and lift the outer side of the steel structure component 14. During the lifting process, the inner hollow layer self-rotating rod 7 and the inner locking self-rotating rod 8 are rotated to the bottom of the steel structure component 14 through the electric rotating shaft connector 6, and the two are seamlessly connected through a precisely designed locking structure. This design can not only effectively share the pressure during the lifting process, but also significantly improve the lifting stability of the symmetrical hooks 4. In addition, when the steel structure component 14 tilts due to external factors (such as wind or improper operation), the inner hollow layer self-rotating rod 7 and the inner locking self-rotating rod 8 can timely share and support the tilting pressure through their interlocking structure, thereby preventing the steel structure component 14 from falling accidentally at high altitude, greatly improving the safety and reliability of long-distance lifting. At the same time, the reinforcing inner ribs 15 set in the balancing hoisting truss 2 further enhance the safety and reliability of the steel structure component 14. This design enhances the overall stability and deformation resistance of the equipment, ensuring efficient operation even under complex working conditions. During the engagement of the inner hollow layer self-rotating rod 7 and the inner locking self-rotating rod 8, the electric push rod 10 in the groove 9 pushes outward, causing the abutment limiting member 11 to extend into the alignment groove opening 13. The outwardly protruding stabilizing rubber particles 12 further enhance the docking stability between the two. This design not only improves the mechanical strength of the locking structure but also effectively reduces the risk of loosening due to vibration or impact. In addition, the anti-slip inner pad layer 5 further enhances the friction between the symmetrical hook 4 and the steel structure being hoisted 14, preventing slippage or displacement during hoisting, thereby ensuring the stability and safety of the hoisting operation. This solution achieves high efficiency, stability, and safety of the hoisting device through multi-level optimization design, and is particularly suitable for long-distance hoisting operations of large-span steel structures.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
