Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to an auxiliary hoisting structure for large modular steel components. Background Technology

[0002] With the rapid development of domestic engineering construction and the gradual increase in the scale of production facilities, the design of steel structures is becoming increasingly large-scale. As steel structure installation is an essential part of engineering construction, its construction difficulty will inevitably increase. Therefore, for large-scale towering steel structures, one of the most effective methods is to assemble the steel structure components into a whole on the ground, that is, "modularization". Then, large hoisting machinery, which is essential on the construction site, is used to place the modules in place, which can ensure safety and reduce costs and increase efficiency.

[0003] In the prior art, a search revealed a Chinese patent disclosing a "large modular steel component auxiliary hoisting structure," application number "202020993953.3." This patent mainly includes a main beam with clamping units fixed to both sides. Each clamping unit includes a crossbeam fixedly connected to the main beam. Two vertical plates extend upwards through grooves connected to a first nut, and another vertical plate extends upwards through a groove connected to a second nut. The clamping screws are symmetrically provided with a first threaded section and a second threaded section, with opposite rotation directions. The first threaded section is helically connected to the first nut, and the second threaded section is helically connected to the second nut. The lower part of the vertical plates has fixing holes, and the same support rod is inserted into the fixing holes of both vertical plates. Although it can be applied to various steel components and has a wide range of applications, and the cooperation of the pressure plate and vertical plates can effectively reduce the swaying of the auxiliary hoisting structure when hoisting steel components, it still requires inserting the steel components into the equipment, making loading inconvenient and increasing the difficulty and danger of loading; it also cannot meet the hoisting requirements of longer steel components. Therefore, this utility model provides an auxiliary hoisting structure for large modular steel components to solve the problems mentioned in the background art. Utility Model Content

[0025] Reference Figure 1-4 This utility model discloses an auxiliary hoisting structure for large modular steel components, comprising a frame 1, two connecting rods 7, sliders 11, an electromagnet 3, and a center plate 2. Baffles 9 are fixedly connected to both ends of the frame 1, and limit plates 8 are fixedly connected to the side of the baffles 9 closest to the frame 1 to prevent the sliders 11 from detaching from the track. The connecting rods 7 are symmetrically fixedly connected between the limit plates 8, and two sliders 11 are slidably connected to the connecting rods 7. The sliders 11 can move horizontally on the connecting rods 7, and each slider 11 is equipped with a second cylinder 12.

[0026] When adjusting the distance, the second cylinder 12 inside the slider 11 is activated, which drives the slider 11 to move horizontally on the connecting rod 7, thereby adjusting the clamping position. The clamping assembly is used to fix the steel component.

[0027] The center plate 2 is fixedly connected to the bottom of the frame 1, and the connecting rod 7 is slidably connected to the center plate 2. The center plate 2 is located between the two sliders 11. The piston rod of the second cylinder 12 is fixedly connected to the outside of the center plate 2. The bottom of the center plate 2 is symmetrically fixed with the first cylinder 4. The bottom end of the piston rod of the first cylinder 4 is fixedly connected to an electromagnet 3. The first cylinder 4 can drive the electromagnet 3 to move up and down.

[0028] In use, after aligning the device with the steel structure, the first cylinder 4 drives the electromagnet 3 to move downwards until the electromagnet 3 is close to the steel component. Then, the electromagnet 3 activates to attract the steel component, and the first cylinder 4 lifts it to the clamping position.

[0029] Each slider 11 has a clamping assembly at its bottom. The clamping assembly includes a U-shaped plate 13 fixed to the bottom of the slider 11, a bidirectional lead screw 17 rotating inside the U-shaped plate 13, and two fixing assemblies symmetrically arranged on the bidirectional lead screw 17. The fixing assemblies include a C-shaped clamping block 14 threaded to the bidirectional lead screw 17, a third cylinder 15 fixedly connected to the inside of the clamping block 14, and an L-shaped clamping plate 16 fixed to the top of the third cylinder 15. The top of the clamping block 14 is slidably connected to the bottom of the U-shaped plate 13. Multiple buffer particles 19 are fixedly provided on the surface of the clamping plate 16. A motor 18 is fixedly mounted on the outside of the U-shaped plate 13, and one end of the central shaft of the bidirectional lead screw 17 passes through the U-shaped plate 13 and is fixedly connected to the output shaft of the motor 18.

[0030] During clamping, the motor 18 starts, driving the bidirectional lead screw 17 to rotate, thereby moving the fixing component to the appropriate position. At the same time, the third cylinder 15 starts, fixing and clamping the steel structure.

[0031] The top of the frame 1 is symmetrically fixed with fixed plates 5, and the fixed plates 5 are rotatably connected with first lifting rings 6. The top of each baffle 9 is fixed with a second lifting ring 10 to assist in the stability during lifting.

[0032] Working principle: When adjusting the distance, the second cylinder 12 inside the slider 11 is activated, which drives the slider 11 to move horizontally on the connecting rod 7, thereby adjusting the clamping position.

[0033] In use, after aligning the device with the steel structure, the first cylinder 4 drives the electromagnet 3 to move downwards until the electromagnet 3 is close to the steel component. Then, the electromagnet 3 activates to attract the steel component, and the first cylinder 4 lifts it to the clamping position.

[0034] During clamping, the motor 18 starts, driving the bidirectional lead screw 17 to rotate, thereby moving the fixing component to the appropriate position. At the same time, the third cylinder 15 starts, fixing and clamping the steel structure.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
