Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, in particular to a large steel cylinder hoisting tool. Background Art

[0002] Large steel cylindrical structures, as core components of modern infrastructure construction, are widely used in marine engineering (such as pier foundations of cross-sea bridges, offshore wind power pile foundations), port construction (such as caisson-type docks, breakwaters), bridge foundations (such as high pile caps in deep water areas) and deep foundation pit support for large buildings (such as underground continuous walls of super-high-rise buildings). Such structures usually have the characteristics of super-large diameter (more than 10 meters), super-high height (tens of meters) and super-heavy tonnage (single unit weight exceeds 1,000 tons), and their lifting operations are highly dependent on the tooling system.

[0003] Traditional tooling mostly adopts an integrated truss or frame structure. Its huge size (usually more than 30 meters in length and weighing tens of tons) requires reliance on heavy-duty transport vehicles or special ships during transportation. It is also restricted by road height and width restrictions and bridge capacity, which greatly increases logistics and time costs. At the same time, large tooling is difficult to adapt to the lifting needs of steel cylinders of different specifications and has poor versatility, which further limits the flexibility of engineering applications. The integrated structure causes local damage and requires the entire tool to be returned to the factory for repair. In addition, the size of the tooling is strongly bound to a specific project and is difficult to reuse. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-Figure 7 The specific implementation modes of the present utility model are further described in detail.

[0025] The utility model includes a lifting block 2, the top of the lifting block 2 is connected to a crane 1, the crane 1 can adjust the position of the lifting block 2, the bottom of the lifting block 2 is circumferentially arranged with a plurality of lifting ropes 3 to form a distributed bearing structure to ensure balanced transmission of the lifting force, the bottom of each lifting rope 3 is provided with a lifting ring 18, the bottom of each lifting ring 18 is provided with an assembly block 4, the outer side of the assembly block 4 is provided with two pairs of bolts 7, the two pairs of bolts 7 are symmetrically arranged with the center line of the assembly block 4 as the symmetry axis, there is a gap between each pair of bolts 7, which is convenient for the subsequent installation of nuts, and two bolts are provided on each side. 7 can further ensure the stability of assembly. Adjacent assembly blocks 4 are matched with connecting blocks 5. Each assembly block 4 is provided with an adjustment component inside. Two first clamping blocks 14 are provided on the top of the adjustment component. The two first clamping blocks 14 are symmetrically arranged with the center line of the assembly block 4 as the symmetry axis. The two first clamping blocks 14 are slidably connected to the top of the assembly block 4. Two second clamping blocks 15 are provided at the bottom of the adjustment component. The two second clamping blocks 15 are symmetrically arranged with the center line of the assembly block 4 as the symmetry axis. The two second clamping blocks 15 are slidably connected to the bottom of the assembly block 4. The first clamping blocks 14 and the second clamping blocks 15 are symmetrically arranged with the center line of the assembly block 4 as the symmetry axis. The second clamping block 15 cooperates with the adjacent connecting block 5. A groove 8 is provided at the bottom of the connecting block 5. The groove 8 cooperates with the second clamping block 15. When the steel cylinder needs to be clamped, the assembly block 4 and the connecting block 5 are first assembled. The connecting block 5 is preliminarily clamped with the assembly block 4 through a plurality of bolts 7 to form a basic annular frame. Then, the first clamping block 14 is driven by the adjustment component to move outward and abut against the top of the connecting block 5. At the same time, the second clamping block 15 also moves outward synchronously and is inserted into the groove 8 of the connecting block 5. In this way, the first clamping block 14 is connected to the connecting block 5 by the bolts 7 and the first clamping block 14. With the coordinated action of the second clamping block 15, multiple assembly blocks 4 and connecting blocks 5 are quickly clamped to form a stable annular tooling body, and then nuts are installed on the top of the bolts 7 respectively to perform secondary fixation on the assembly body and the connecting block 5. This double fixing mechanism greatly improves the stability and safety of the tooling system. A plurality of hydraulic clamping claws 6 are provided at the bottom of each assembly block 4. After the tooling system is assembled, the hydraulic clamping claws 6 can further clamp and fix the steel cylinder to better adapt to steel cylinders of different diameters, thereby improving the versatility and flexibility of the tooling system.

[0026] The adjusting component includes a transmission block 9, which is rotatably connected to the inner side of the assembly block 4. The inner side of the transmission block 9 has a polygonal depression, and the transmission block 9 can be driven to rotate through the polygonal interface. A first bevel gear 10 is provided on the outer side of the transmission block 9, and a second bevel gear 11 is meshed on the outer side of the first bevel gear 10. A bidirectional threaded rod 12 is provided on the inner side of the second bevel gear 11. The middle part of the bidirectional threaded rod 12 is rotatably connected to the assembly block 4. The transmission block 9 drives the fixedly connected first bevel gear 10 to rotate, and the first bevel gear 10 drives the meshed second bevel gear 11 to rotate, thereby realizing the rotation of the bidirectional threaded rod 12.

[0027] Two moving blocks 13 are provided on the outer side of the bidirectional threaded rod 12. The two moving blocks 13 are symmetrically arranged with the radial center line of the bidirectional threaded rod 12 as the symmetry axis. The bottom of the moving block 13 is slidably connected with the assembly block 4. The rotation of the bidirectional threaded rod 12 can drive the threadedly connected moving blocks 13 to move outward or inward at the same time. The outer side of each moving block 13 is interconnected with the inner side of the first clamping block 14 and the second clamping block 15. The moving block 13 can drive the corresponding first clamping block 14 and the second clamping block 15 to move synchronously.

[0028] A rack 16 is provided at the outer end of the moving block 13 on one side, and a spur gear 17 is provided at the top of the rack 16. The outer side of the spur gear 17 is connected to a lifting ring 18. When the moving block 13 on one side moves, the rack 16 at the outer end can be driven to move, and the rack 16 can drive the spur gear 17 meshing at the top to rotate, thereby driving the lifting ring 18 to rotate. That is to say, when the assembly block 4 is not installed with the connecting block 5, the lifting ring 18 will be in a horizontal state and hidden at the top of the assembly block 4. When the assembly block 4 is installed with the connecting block 5, the spur gear 17 can be driven to rotate, and the lifting ring 18 can be driven to rotate upward to a vertical state, and then hoisting is carried out. After the hoisting is completed, it continues to be adjusted to a horizontal state and hidden inside the assembly block 4, which is convenient for batch stacking and transportation.

[0029] When the utility model is used, when clamping the steel cylinder, the assembly block 4 and the connecting block 5 are first assembled, and the connecting block 5 is preliminarily clamped with the assembly block 4 through a plurality of bolts 7 to form a basic annular frame. Then, the first clamping block 14 is driven by the adjustment component to move outward and abut against the top of the connecting block 5. At the same time, the second clamping block 15 is also synchronously moved outward and inserted into the groove 8 of the connecting block 5. In this way, through the coordinated action of the bolts 7, the first clamping block 14 and the second clamping block 15, the plurality of assembly blocks 4 and the connecting block 5 are quickly clamped to form a stable annular tooling body, and then the bolts 7 are installed on the top of the bolts 7 respectively. The assembly and the connecting block 5 are fixed for the second time. This double fixing mechanism greatly improves the stability and safety of the tooling system. At the same time, it drives the spur gear 17 to rotate, and drives the lifting ring 18 to rotate upward to a vertical state, and then hoisting is carried out. A plurality of hydraulic clamping claws 6 are provided at the bottom of each assembly block 4. After the assembly of the tooling system is completed, the hydraulic clamping claws 6 can further clamp and fix the steel cylinder, better adapt to steel cylinders of different diameters, and improve the versatility and flexibility of the tooling system. After the hoisting is completed, the lifting ring 18 is adjusted to a horizontal state and hidden inside the assembly block 4, which is convenient for batch stacking and transportation of the assembly blocks 4.
