Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to a hydraulic lifting device for steel structure construction. Background Technology

[0002] Steel structure construction refers to the process of assembling steel components into a structural system with a certain load-bearing capacity through methods such as cutting, welding, and bolting, using steel as the main material. Steel structure construction has advantages such as being lightweight, high-strength, fast in construction, and having good seismic performance, and is therefore widely used in engineering fields such as high-rise buildings, bridges, stadiums, and industrial plants.

[0003] In the existing technology, the support structure of existing steel structure construction equipment is fixed and cannot be flexibly adjusted according to the different widths of steel structure components. This makes it difficult for the same equipment to adapt to the lifting operations of steel structures of various specifications. Therefore, we propose a hydraulic lifting device for steel structure construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a hydraulic lifting device for steel structure construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic lifting device for steel structure construction includes a base, a hydraulic cylinder fixedly connected to the top of the base, a ring fixedly fitted on the outer wall of the hydraulic cylinder, a threaded mating sleeve fixedly connected to the outer wall of the ring, a mating rod threadedly connected to the inner wall of the threaded mating sleeve, a lifting plate fixedly connected to the top of the output end of the hydraulic cylinder, two strip grooves formed on the outer wall of the lifting plate, side rods slidably connected to the inner walls of the two strip grooves, gaskets fixedly fitted on the outer walls of the two side rods, multiple insertion holes formed on the inner walls of the two strip grooves, threaded holes formed on the outer walls of the two side rods, bolts threadedly connected to the inner walls of the two threaded holes, and a limiting component provided on the top of the lifting plate.

[0007] Preferably, the limiting component includes a long screw, the top of the lifting plate has an installation hole, the inner wall of the installation hole is threadedly connected to the bottom outer wall of the long screw, the outer wall of the long screw is slidably fitted with a top plate, and the outer wall of the top plate has two rectangular slots, thereby limiting the steel structure by setting the limiting component.

[0008] Preferably, the outer wall of the base is provided with multiple fixing holes for the installation of foot spikes.

[0009] Preferably, the outer wall of the bolt is slidably connected to the inner wall of the insertion hole, and the side rod is fixed in the strip groove by setting the bolt.

[0010] Preferably, the bottom of the shim is slidably connected to the top of the lifting plate, and the shim is moved by an auxiliary side rod.

[0011] Preferably, the inner walls of the two rectangular slots are slidably connected to the outer walls of the two side rods, and the auxiliary top plates of the two rectangular slots are installed between the two side rods.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution utilizes the sliding adjustment of side rods within the slot and bolt fixing to quickly adapt to steel structure components of varying widths, significantly enhancing the equipment's versatility and applicability. The combination of a top plate and side rod fixing structure, along with a rigid connection at the hydraulic cylinder output end, effectively improves overall stability during lifting, preventing steel structure swaying or displacement. Connecting multiple hydraulic cylinders via connecting rods creates stable linkage, enabling multiple units to work collaboratively and improving the construction efficiency of large steel structures. The use of bolts and long threaded rods for fixing simplifies and expedites equipment adjustment and installation, significantly reducing construction preparation time. Overall, this solution is suitable for steel structure construction needs of various specifications and shapes, significantly reducing equipment configuration costs and increasing construction flexibility.

Matching threads are machined at both ends of the mating rod 6.

[0023] Multiple hydraulic cylinders 3 distribute the flow output from the hydraulic pump to each hydraulic cylinder 3 proportionally through a flow divider and combiner valve, ensuring that each hydraulic cylinder 3 receives the same flow, thereby achieving synchronous movement.

[0024] A lifting plate 7 is fixedly connected to the top of the output end of the hydraulic cylinder 3. The lifting plate 7 is connected to the piston rod of the hydraulic cylinder 3 by a flange. Two strip grooves 8 are opened on the outer wall of the lifting plate 7. Side rods 9 are slidably connected to the inner walls of the two strip grooves 8. Gaskets 10 are fixedly sleeved on the outer walls of the two side rods 9. Gaskets 10 are made of polytetrafluoroethylene composite material.

[0025] The inner walls of the two strip grooves 8 are provided with multiple insertion holes 11, which are arranged horizontally.

The two side rods 9 can be moved along the two strip grooves 8 through the two washers 10 to adjust the distance between the two side rods 9 to meet different width requirements. Then, the two bolts 12 are screwed into the two threaded holes through the two insertion holes 11 respectively to fix the two side rods 9 in the two strip grooves 8 respectively. The top plate 13 is fitted onto the two side rods 9 through the two rectangular long slots 14.
