Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a mobile frame lifting device. Background Art

[0002] During the construction of a steel structure project in a comprehensive utilization land project of a vehicle depot, it is necessary to install 36 pot-type seismic isolation bearings with a weight of nearly 200 kg on the floor slab of the building, and the distance between each bearing is 9 m to 18 m. Due to the limited bearing capacity of the floor slab, traditional lifting equipment such as truck cranes and crawler cranes cannot be used.

[0003] The traditional hoisting method is to select a larger crane to lift the bearing to the installation point at the edge of the site; or after the floor slab is fully covered with roadbed boards, a truck crane with a lifting capacity of less than 25 t is selected to install it on the floor slab.

[0004] If a lifting operation radius of nearly 100 m needs to be satisfied, an extra-large crawler crane must be selected for off-site hoisting machinery, and the mechanical leasing and usage costs are very high. If the floor slab is fully covered with roadbed boards and then a light truck crane is used to install it on the floor slab, since the installation of the bearing is in the early stage of the project, all floor slabs need to be chiseled and waterproofed again, the roadbed boards need to be moved at any time, and it is difficult to position the crane. It has high requirements for the narrow construction site, large coordination difficulty, and long leasing time for the roadbed boards and the crane, resulting in high costs. Summary of the Utility Model

[0005] In view of the above problems, the purpose of the utility model is to provide a mobile frame lifting device to solve the problem that a low-load floor slab cannot bear general crane machinery for lifting and transporting items.

[0006] The utility model provides a mobile frame lifting device, including: a frame structure surrounded by four main trusses and a chain hoist arranged at the upper end of the frame structure. Among them,

[0007] Reinforcing connecting rods are arranged between two adjacent main trusses at the upper end of the frame structure, and chain hoist fixing components are arranged on each main truss at the upper end of the frame structure. Among them,

[0008] One end of the chain hoist is fixed on the chain hoist fixing component, and the other end is fixed on the component to be moved;

[0009] A component limiting assembly for the component to be moved is arranged at the lower end of the frame structure. Among them,

[0010] The component limiting assembly for the component to be moved is used to limit the component to be moved at the lower end of the frame structure and move it to the target position under the action of the chain hoist and the frame structure.

[0011] In addition, a preferred structure is that the fixed assembly of the chain block includes lug bottom plates arranged on each main truss at the upper end of the frame structure, and lugs arranged on each lug bottom plate, wherein,

[0012] Through holes are provided on each lug, and the lug is connected to one end of the chain block through the through holes.

[0013] In addition, a preferred structure is that the lug bottom plates are fixed to the upper end of the main truss by welding.

[0014] In addition, a preferred structure is that the limiting assembly for the member to be moved includes a movable baffle plate movably arranged at the lower end of one of the main trusses, and fixed baffle plates arranged at the lower ends of the other three main trusses, wherein,

[0015] The three fixed baffle plates are connected to each other to enclose a limiting space for limiting the member to be moved.

[0016] In addition, a preferred structure is that the member to be moved enters the limiting space by opening the movable baffle plate.

[0017] In addition, a preferred structure is that each reinforcing connecting rod is welded to two adjacent main trusses, and the reinforcing connecting rod is used to strengthen the acting force between adjacent main trusses.

[0018] In addition, a preferred structure is that support bottom plates are respectively arranged at the four corners of the bottom of the frame structure, and the support bottom plates are fixed to the frame structure by welding.

[0019] In addition, a preferred structure is that universal wheels are arranged on the support bottom plates, and the universal wheels are used to move the frame structure.

[0020] As can be seen from the above technical solutions, the mobile frame hoisting device provided by the present utility model forms a frame structure by the main trusses, and a chain block is arranged on this frame structure. The heavy components are moved to the target position through the chain block and the universal wheels arranged at the bottom, thereby solving the problem that the current low-load floor cannot bear general crane machinery for hoisting and transporting items. This mobile frame hoisting device has a light self-weight, a simple structure, and is convenient to manufacture. While solving the problem of hoisting heavy components, it can also save the rental costs of truck cranes, crawler cranes, and tower cranes, thereby saving costs.

Among them, a reinforcing connecting rod 2 is provided between two adjacent main trusses 1 at the upper end of the frame structure, and a chain block fixing assembly is provided on each main truss 1 at the upper end of the frame structure. One end of the chain block is fixed on the chain block fixing assembly, and the other end is fixed on the member to be moved; a limiting assembly for the member to be moved is provided at the lower end of the frame structure. The limiting assembly for the member to be moved is used to limit the member to be moved at the lower end of the frame structure and move it to the target position under the action of the chain block and the frame structure.

[0032] Specifically, the chain block fixing assembly includes a lug bottom plate 3 provided on each main truss 1 at the upper end of the frame structure and a lug 4 provided on each lug bottom plate 3. A through hole 41 is provided on each lug 4, and the lug 4 is connected to one end of the chain block through the through hole 41. The lug bottom plate 3 is fixed to the upper end of the main truss 1 by welding.

[0033] Among them, the limiting assembly for the member to be moved includes a movable baffle 7 movably provided at the lower end of one main truss 1 and fixed baffles 6 provided at the lower ends of the other three main trusses 1. The three fixed baffles are respectively a first fixed baffle 61, a second fixed baffle 62, and a third fixed baffle 63. A limiting space for limiting the member to be moved is formed by connecting the three fixed baffles (the first fixed baffle 61, the second fixed baffle 62, and the third fixed baffle 63) and the movable baffle 7. The member to be moved enters the limiting space by opening the movable baffle 7.

[0034] Each reinforcing connecting rod 2 is welded to two adjacent main trusses 1, and the reinforcing connecting rod 2 is used to strengthen the acting force between adjacent main trusses 1.

[0035] Among them, support bottom plates 8 are respectively provided at the four corners of the bottom of the frame structure, and the support bottom plates 8 are fixed to the frame structure by welding.

[0039] Step 2: Connect the other ends of the four manual hoists to the lifting lugs on the member to be moved respectively.

[0040] Step 3: Adjust the manual hoist so that the member to be moved is lifted about 100 mm off the ground.

[0041] Step 4: Close the movable baffle 7, and push the entire frame structure so that the member to be moved moves to the designated position (target position) along with the mobile frame hoisting device.

[0042] Step 5: Slowly adjust the manual hoist and install the member to be moved at the designated position.

[0043] The temporary results and states obtained in the implementation of the above process:

[0044] After Step 1 is completed, it is possible to prepare for hoisting the member to be moved.

[0045] After Step 2 is completed, after hoisting the member to be moved, it is prepared to transport the member to be moved.

[0046] After Step 3 is completed, it is for moving and transporting the member to be moved.
