Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of hoisting equipment technology, and more specifically, to an integral hoisting fixture for ultra-large and ultra-long span steel trusses. Background Technology

[0002] In the field of modern architecture, large-span steel structure buildings are widely used in the construction of large-scale infrastructure such as stadiums, convention centers, and transportation hubs due to their excellent spatial performance. Taking the Bird's Nest Stadium as an example, its unique spatial steel structure shape not only highlights architectural aesthetics but also showcases the charm of large-span steel structures in architecture. As the core load-bearing component of large-span steel structure buildings, the installation quality and efficiency of ultra-large and ultra-long steel trusses directly affect the progress, safety, and cost of the entire construction project.

[0003] Traditional steel truss hoisting methods typically employ decentralized hoisting, which involves disassembling the steel truss into multiple small components, hoisting them separately, and then assembling them in mid-air. This method not only significantly increases the amount of work at height and raises the safety risks of construction, but also greatly reduces construction efficiency and extends the project duration. As the scale of buildings continues to expand and the application of ultra-large and ultra-long span steel trusses becomes more and more common, the limitations of traditional hoisting methods are becoming increasingly apparent.

[0034] like Figures 1-4 As shown, it illustrates an integral hoisting fixture for an ultra-large, ultra-span steel truss according to this disclosure, comprising:

[0035] The hoisting frame 1 has a hoisting pull ring 2 on its upper end face;

[0036] The horizontally inserted hoisting assembly 3 is located at the bottom of the hoisting frame 1;

[0037] Lifting switching component 4 is installed on the inner wall of the hoisting frame 1;

[0038] The horizontal insertion hoisting assembly 3 includes a horizontal insertion notch 3-1, which is opened inside the hoisting frame 1. The horizontal insertion notch 3-1 has an insertion hole 3-2. One end of the insertion hole 3-2 is connected to the side wall of the hoisting frame 1. A connecting shaft 3-3 is inserted into the insertion hole 3-2. A lifting tube 3-4 is provided on the side wall of the connecting shaft 3-3. The lifting tube 3-4 is fitted inside the connecting shaft 3-3. An embedding groove 3-5 is provided on the upper end face of the lifting tube 3-4.

[0039] The lifting and switching assembly 4 includes a tilting cavity 4-1, which is located on the bottom surface of the hoisting frame 1. A tilting ball 4-2 is installed inside the tilting cavity 4-1, and the tilting ball 4-2 is connected to the tilting cavity 4-1 by a pin. A tilting frame 4-3 is installed on the side wall of the tilting ball 4-2, and the tilting frame 4-3 is connected to the lifting pipe 3-4 by a pin. The connecting shaft 3-3 passes through the tilting ball 4-2.

[0040] In some examples, a hoisting frame 1 that meets the design requirements is selected to ensure that its strength and size meet the hoisting requirements of ultra-large and ultra-long span steel trusses. Four hoisting rings 2 are installed on the upper surface of the hoisting frame 1 according to the design position.

[0041] Connect the connecting bushing 6 to the hoisting frame 1 to ensure the accurate installation position of the connecting bushing 6. Its side wall has a recessed structure, which can play a specific connection or positioning role in subsequent use.

[0042] A horizontal insertion notch 3-1 is made inside the bottom of the hoisting frame 1, and an insertion hole 3-2 is made on the horizontal insertion notch 3-1 according to the design dimensions, ensuring that one end of the insertion hole 3-2 is connected to the side wall of the hoisting frame 1. The connecting shaft 3-3 is inserted into the insertion hole 3-2, and a positioning key 3-7 is set on the side wall of the connecting shaft 3-3. The lifting tube 3-4 is installed inside the connecting shaft 3-3, so that the mounting groove 3-5 set on the upper end face of the lifting tube 3-4 faces upward, so as to connect with the steel truss and other components later.

[0043] A tilting cavity 4-1 is opened on the bottom surface of the hoisting frame 1. A tilting ball 4-2 is installed in the tilting cavity 4-1 and connected to the tilting cavity 4-1 by a pin, so that the tilting ball 4-2 can rotate flexibly in the tilting cavity 4-1. A locking plate 4-6 is installed on the side wall of the swing frame 4-5. At the same time, a drive disc 8 is installed at the end of the connecting shaft 3-3, so that the locking plate 4-6 fits into the drive disc 8, which facilitates the control of the movement of the locking plate 4-6 by the drive disc 8.

[0044] like Figures 1-4As shown in the figure, this embodiment proposes that the inner sidewall of the insertion hole 3-2 is provided with a positioning keyway 3-6, and the sidewall of the connecting shaft 3-3 is provided with a positioning key 3-7, and the positioning key 3-7 and the positioning keyway 3-6 are inserted and fixed together.

[0045] In some examples, a positioning keyway 3-6 is provided on the inner wall of the insertion hole 3-2 so that the positioning key 3-7 is inserted and fixed with the positioning keyway 3-6, ensuring that the connecting shaft 3-3 is installed firmly and in an accurate position.

[0046] For example, such as Figure 4 As shown, the inner wall of the hoisting frame 1 is provided with a locking cavity 4-4, and a swing frame 4-5 is connected to the locking cavity 4-4 by a pin. The side wall of the swing frame 4-5 is provided with a locking piece 4-6.

[0047] In some examples, when the swing bracket 4-5 inside the locking cavity 4-4 swings, the locking plate 4-6 presses against the end face of the connecting shaft 3-3, thereby fixing the insertion position of the connecting shaft 3-3.

[0048] For example, such as Figure 1 As shown, a force-bearing shaft 5 is provided on the lower end face of the lifting ring 2. The force-bearing shaft 5 is located on the upper end face of the lifting frame 1. There are 4 lifting rings 2, and the 4 lifting rings 2 are located at the four corners of the upper end face of the lifting frame 1.

[0049] In some examples, a force-bearing shaft 5 is installed on the lower end face of each lifting ring 2, and the force-bearing shaft 5 is firmly set at the four corners of the upper end face of the lifting frame 1 to ensure uniform force and stability during lifting.

[0050] For example, such as Figure 4 As shown, a relief cavity 4-7 is provided on the lower end face of the locking cavity 4-4. The relief cavity 4-7 is connected to the locking cavity 4-4, and the locking piece 4-6 is embedded in the relief cavity 4-7.

[0051] In some examples, a relief cavity 4-7 is provided on the lower end face of the locking cavity 4-4, so that the relief cavity 4-7 is connected to the locking cavity 4-4. When the swing frame 4-5 swings, the locking piece 4-6 can be embedded in the relief cavity 4-7 to realize the locking function of the relevant components.

[0052] For example, such as Figure 1 As shown, a connecting bushing 6 is connected to the hoisting frame 1. The side wall of the connecting bushing 6 is a recessed structure. A lifting block 7 is provided on the inner side wall of the hoisting frame 1. The lifting block 7 is located on the opposite side walls inside the hoisting frame 1.

[0053] In some examples, lifting blocks 7 are installed on opposite sides of the inner wall of the hoisting frame 1 to securely fix the lifting blocks 7 in a predetermined position.

[0054] For example, such as Figure 1As shown, a drive disc 8 is provided at the end of the connecting shaft 3-3, and the locking piece 4-6 is in contact with the drive disc 8.

[0055] In some examples, drive disk 8 is used to pull out or insert connecting shaft 3-3.

[0056] For example, such as Figure 1 As shown, the side wall of the lifting block 7 is provided with a relief and fitting arc-shaped surface 9.

[0057] In some examples, the sidewall of the lifting block 7 is provided with a relief-fitting arc surface 9 for use with other components. The relief-fitting arc surface 9 is specifically designed to provide positioning when the I-beam is lifted after being inserted laterally.

[0058] In use, the corresponding part of the ultra-large and ultra-span steel truss is connected to the mounting groove 3-5 of the lifting tube 3-4 of the horizontal insertion lifting assembly 3 of the lifting clamp. It can be fixed by appropriate connectors (such as bolts) to ensure a firm connection. According to the actual lifting requirements, by operating the connecting shaft 3-3 and other components, the rotating ball 4-2, the rotating frame 4-3 and the lifting tube 3-4 are driven to move, so as to switch the lifting angle or position to adapt to different lifting conditions. When lifting tubular materials, the connecting shaft 3-3 is fully inserted into the insertion hole 3-2 by operating the drive disc 8. At this time, the connecting shaft 3-3 also passes through the lifting tube 3-4, so that the lifting tube 3-4 is fixed. At this time, the mounting groove 3-5 on the lifting tube 3-4 fixes the tubular material to prevent accidental movement or loosening during the lifting process. After the rotating swing frame 4-5 is rotated, the locking piece 4-6 is pressed against the end face of the connecting shaft 3-3, so that the insertion position of the connecting shaft 3-3 is fixed.

[0059] When hoisting the I-beam, after pulling out the connecting shaft 3-3, flip the lifting pipe 3-4 into the flipping cavity 4-1. At this time, the I-beam can be limited by the arc-shaped surface 9 on the lifting block 7 and then lifted.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
