Description

Technical Field

[0001] The invention relates to the technical field of steel structure assembled buildings, in particular to a hoisting device and a hoisting method for modular houses. Background Art

[0002] Modular construction is a process of splitting a building into modular "units". The module structure, decoration, water and electricity, equipment pipelines, bathroom facilities and other construction processes are efficiently completed in the factory, and then quickly assembled into the entire building on site through reliable connection technology. This technology moves the building from the construction site into the factory, greatly shortens the construction period and reduces the difficulty of construction. It is one of the green construction methods with the highest degree of industrialization in the current construction.

[0003] The modular method of steel structure is widely used in single- and multi-story smart houses, cultural and tourism cabins and other buildings. From the characteristics of modular buildings, it can be seen that each module unit is a complete structural system composed of top beams, bottom beams and columns. Adjacent modules transfer loads and coordinate deformation through corresponding connection nodes, so that multiple units form an overall structure of a certain scale.

[0004] After the above installation is completed to form a single cabin, it is often necessary to lift and assemble according to actual requirements to form a multi-cabin structure to adapt to different scenarios due to functional requirements. The conventional lifting method is to set lifting lugs at relevant locations of the module, and to complete the lifting of a single module by connecting the crane hook with the reserved lifting lugs during on-site construction. This lifting method has the following disadvantages:

[0005] 1. The lifting lugs often protrude from the surface of the structure and need to be removed after lifting, otherwise it will affect the subsequent module assembly. If the modules need to be reassembled according to the needs, the lifting lugs need to be re-welded before lifting again, which is time-consuming and labor-intensive.

[0006] 2. The upper lifting tools are not highly adaptable, and the length is generally fixed, which cannot be adjusted according to the size of the building. At the same time, the upper lifting tools are large in size, which also brings inconvenience to warehousing and transportation. Summary of the invention

[0007] The object of the present invention is to provide a hoisting device and a hoisting method for modular houses to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions: A hoisting device for modular houses, comprising a hoisting member, wherein the hoisting member comprises a left telescopic beam and a right telescopic beam, and two connecting beams are installed between the left telescopic beam and the right telescopic beam. The sizes of the left telescopic beam and the right telescopic beam are adjusted based on the house to be hoisted, and can be applied to houses of various sizes, with a wide range of applications;

[0009] A lifting lug assembly, wherein the lifting lug assembly is provided in a plurality of pieces and the lifting lug assembly is disassembled and mounted on both ends of the left telescopic beam and the right telescopic beam. The disassembly can reduce the volume and facilitate transportation;

[0010] The lifting ear assembly includes a main body, which is a hollow structure, and a rotating part is rotatably installed in the main body, and the rotating part has a lifting ear. Four elastic buckles are installed between the rotating part and the main body, and the elastic buckles are inserted into the ends of the left telescopic beam and the right telescopic beam for clamping. The rotating part is rotated to control the elastic buckles to separate from the left telescopic beam and the right telescopic beam. The lifting ear assembly is easy to remove and the lifting efficiency of the rent is improved.

[0011] Furthermore, the lifting ear assembly is detachably connected to a house via an elastic buckle, and the house includes corner columns. The corner columns and the surfaces of the left telescopic beam and the right telescopic beam are all provided with holes, and the elastic buckle is connected to the holes. The preset holes do not require welding of the house or installation of lifting ears, thereby reducing the workload of welding before lifting and cutting after lifting.

[0012] Furthermore, the left telescopic beam and the right telescopic beam are composed of three sections of pipes with successively smaller cross-sections, which is convenient for telescopically adjusting the length of the left telescopic beam and the right telescopic beam. A plurality of elliptical bolt holes are provided on the surface of the pipes, and bolts are screwed into the elliptical bolt holes. The pipes are fixed with bolts to ensure that the pipes will not shorten.

[0013] Furthermore, the elastic buckle includes a telescopic block and a flange fixed on the telescopic block. A spring is provided on the surface of the telescopic block. The other end of the spring is connected to a rotating member. A fixing buckle for fixing the spring is provided on the surface of the rotating member. The telescopic block is supported by the spring to ensure that the telescopic block is stably stuck in the hole without falling off, which is safe and reliable.

[0014] A method for hoisting a hoisting device for a modular house comprises the following steps:

[0015] Step 1: Prefabrication: Select a number of steel materials and corner columns to prefabricate the house, and process holes on the surface of the corner columns;

[0016] Step 2, debugging: select corresponding connecting beams, left telescopic beams, and right telescopic beams based on the length and width of the house, adjust the lengths of the left telescopic beams and the right telescopic beams, and connect them with connecting beams;

[0017] Step 3, fixation: turn the rotating part of the lifting ear assembly to control the four telescopic blocks to move into the main body, insert the main body into the holes on the surface of the left telescopic beam, the right telescopic beam and the corner column, and the spring pushes the telescopic blocks to clamp the holes;

[0018] Step 4: Hoisting: Connect the four-claw hook to the crane and the left telescopic beam and the right telescopic beam to hoist the house;

[0019] Step 5, Disassembly: Turn the rotating part to control the four telescopic blocks to separate from the hole, and remove the lifting ear assembly.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) Holes are preset in the corner columns of the house, and telescopic blocks are used to connect the lifting lug assembly to the house with the holes. There is no need to weld the lifting lugs on the house structure, which reduces the workload of welding before lifting and cutting after lifting. The detachable lifting lug assembly is used as the stress point, and the overall stress of the upper lifting parts is reasonable, which will not affect the exterior finish of the house, the internal structural components, and home appliances and home furnishings, and meet the needs of integrated building decoration.

[0022] (2) The size of the left telescopic beam and the right telescopic beam can be flexibly adjusted according to the length of the house to be hoisted, which solves the disadvantage that traditional hoisting tools can only be used for hoisting houses of a single size. It has a wide hoisting range and strong adaptability, and can be used for on-site hoisting of houses of various sizes.

[0023] (3) After the lifting is completed, the lifting lugs, left telescopic beam and right telescopic beam can be removed to complete the dismantling work. They can be reused many times.

[0024] (4) The left and right telescopic beams are sized to enable quick installation through elliptical bolt holes; they can be quickly disassembled and retracted after lifting, and their small size makes them easy to transport and store. BRIEF DESCRIPTION OF THE DRAWINGS
