Description

Technical Field

[0001] This utility model relates to the field of steel truss technology, specifically a modular umbrella-shaped steel truss supportless lifting device. Background Technology

[0002] Research on the formwork construction of umbrella-shaped steel trusses for silo roofs is an important direction in the application of slipform technology in silo engineering. In silo structures, the design and construction of the roof plays a crucial role in the stability and safety of the entire silo. As a spatial structure, umbrella-shaped steel trusses offer advantages such as light weight, high strength, and rational stress distribution, effectively transferring loads and improving the load-bearing capacity of the silo roof.

[0003] In traditional steel truss lifting operations, steel beams are fixed to the top of the warehouse wall, and electric hoists are suspended at both ends of the steel beams. Two electric hoists can be suspended from one steel beam, and the steel truss is lifted using the hook device of the electric hoists. Since the steel truss on the warehouse roof is umbrella-shaped, the four electric hoists on the two steel beams can only fix the steel truss at four points. In the overall hoisting of the steel truss, the stability is poor. At the same time, when the steel truss is large and heavy, the power of the four electric hoists may not be able to support the lifting of the steel truss. Utility Model Content

[0022] Please see Figure 1-4 As shown, a modular umbrella-shaped steel truss supportless lifting device includes a silo body 1. The silo body 1 allows for the storage of materials, commonly including grain and coal. Large grain silos enable efficient and large-capacity storage, ensuring safe reserves and a stable supply of grain. In the coal sector, as a major energy resource, the storage and circulation of coal are crucial for ensuring energy supply. Silos, with their excellent sealing and storage capacity, are a common choice for coal storage. Similarly, in the mining industry, temporary storage of ore also requires... The silo is constructed to facilitate subsequent transportation and processing. It also includes fourteen sets of mounting components 2 arranged in a circular array at the top of the silo body 1. Each mounting component 2 includes a clamping plate 21 located inside the silo body 1 and a positioning plate 22 located outside the silo body 1. The clamping plate 21 and the positioning plate 22 have the same shape. A horizontal plate 23 is fixed between the clamping plate 21 and the positioning plate 22. An adjusting plate 24 is slidably connected to the outer side of the horizontal plate 23. Positioning seats 25 are fixed to the outer sides of both the adjusting plate 24 and the positioning plate 22. Bolts 2 are threaded onto the inner wall of the positioning seats 25. 6; A vertical plate 27 is fixed to the top of the horizontal plate 23, and both the vertical plate 27 and the horizontal plate 23 are set in an I-shape; a hanging plate 28 is fixed to one side of the vertical plate 27, and a through hole 29 is opened on the inner wall of the hanging plate 28; by setting fourteen sets of installation components 2 at the top of the bin 1, fourteen electric hoists 3 can be installed easily. During installation, the clamping plate 21 and the adjusting plate 24 are clamped on the bin wall at the top of the bin 1. A horizontal plate 23 is fixed between the clamping plate 21 and the positioning plate 22. The adjusting plate 24 is moved so that the distance between the clamping plate 21 and the adjusting plate 24 is the same as the wall thickness of the bin 1. When moving, the 24 slides on the horizontal plate 23, and then the bolt 26 is screwed into the positioning seat 25 on the positioning plate 22. After passing through the positioning plate 22, the bolt 26 is screwed into the positioning seat 25 on the adjusting plate 24, so that the distance between the adjusting plate 24 and the positioning plate 22 is limited, thereby fixing the clamping plate 21 and the adjusting plate 24 to the top of the bin 1. The vertical plate 27 is fixed on the horizontal plate 23, and the hanging plate 28 is fixed on one side of the vertical plate 27. The hanging plate 28 has a through hole 29, which makes it easy for the hook 32 on the electric hoist 3 to be hung inside, so that the electric hoist 3 is connected to the installation assembly 2.

[0023] Fourteen electric hoists 3 are installed on the outside of the installation components 2 for lifting the umbrella-shaped steel truss. Each of the fourteen electric hoists 3 is installed on the outside of the fourteen installation components 2. The umbrella-shaped steel truss can be lifted using these fourteen electric hoists 3. Each electric hoist 3 includes a motor drive box 31, which is located inside the housing 1. A hook 32 is fixed to the top of the motor drive box 31 and engages with the inside of the through hole 29. A chain 33, made of alloy copper, is installed inside the motor drive box 31. A connecting block 34 is located at the bottom of the chain 33, and a hook 35 is located at the bottom of the connecting block 34. The core power source of the electric hoist 3 is the electric motor inside the motor drive box 31. When the motor is powered on, it will generate rotational motion, driving the hoist winch to rotate, and lifting or lowering the steel truss through the chain 33. The winch is an important component of the electric hoist 3, responsible for winding and releasing the chain 33. The chain 33 can realize the lifting or lowering of the steel truss. The hook 32 can facilitate the connection between the motor drive box 31 and the installation component 2. The connecting block 34 can facilitate the connection between the chain 33 and the hook 35. The hook 35 can hook the umbrella-shaped steel truss and lift it.

[0024] Working principle: Fourteen sets of installation components 2 are installed at the top of the silo 1. Then, fourteen electric hoists 3 are hooked into the through holes 29 on the hanging plate 28 through hooks 32. The fourteen hooks 35 of the electric hoists 3 are symmetrically and evenly distributed to hook the steel truss beam. The computer control box is switched to manual control mode. Through manual control, the chain 33 of each electric hoist is adjusted to a basically consistent tension (by manually shaking to check the tension of the chain 33). The hoisting is initiated. Fourteen ten-ton electric hoists 3 are connected to the control box to synchronously lift the truss. When the truss is 20 cm off the ground, stability is observed for two hours to check for deformation of the truss components, silo wall clamps, and silo wall. After checking that there are no problems, a high-altitude construction safety net is installed at the bottom of the components. Then, the computer control box is switched to automatic control mode. The steel truss is synchronously lifted by computer automatic control and manual supervision. The walking speed of the electric hoists 3 is controlled at 18 cm per minute. For every 1.8 meters lifted, observation is required for 20 minutes. This process is repeated until the height of the bracket exceeds the bracket height by 150mm. Then, the bracket is installed. After all the brackets are installed, three steel trusses are lowered to the bracket positions using electric hoists, temporarily fixed by electric welding, and then adjusted and firmly welded.
