Description

Technical Field

[0001] This utility model relates to the field of steel structure construction equipment, and in particular to a temporary stabilization device for aerial assembly of steel structures. Background Technology

[0002] Currently, steel structure projects are increasingly common in building construction. In steel structure installation, steel beams, columns, and other steel structural components inevitably need to be assembled in mid-air. Solving the problem of safely and conveniently assembling these components in the air is a pressing issue. Temporary supports are needed to ensure the steel structure is stable during high-altitude assembly.

[0003] Currently, the temporary stabilization methods commonly used in the aerial assembly of steel structures mostly employ scaffolding support or a single hoisting and fixing structure. Scaffolding support requires the construction of a large number of ground-based frames, which not only consumes a lot of materials and has a long construction period, but also makes it impossible to achieve precise height adjustment of components. A single hoisting and fixing structure relies on the continuous force of the lifting equipment and lacks multi-directional stabilization constraints, making it easy for components to shift due to factors such as wind and hoisting sway, affecting installation accuracy and even posing safety hazards.

[0025] Example 1

[0026] See Figures 1 to 3 This utility model provides a temporary stabilization device for steel structure aerial assembly, including a bottom frame 1 and a movable frame 2 slidably connected to the bottom frame 1. The top of the movable frame 2 is fixed to the ground by several inclined bracing systems 3, and also includes a lifting system 4 for moving the movable frame 2.

[0027] The bottom frame 1 includes two parallel rectangular frames 5, which are fixedly connected by several uprights 6. The uprights 6 are located at the four corners of the rectangular frames 5, and a connector 7 is fixedly installed on the upper part of each upright 6. The connector 7 has through holes.

[0028] The movable frame 2 includes a rectangular lifting platform 8. A sliding rod 9 is fixedly installed at each of the four corners of the lower surface of the lifting platform 8. The sliding rod 9 slides in the through hole of an adjacent connector 7.

[0029] A rectangular reinforcing frame 10 is fixedly installed on the upper part of the sliding rod 9. The reinforcing frame 10 is fixedly connected to the four sliding rods 9 respectively. A hanging ring 11 is fixedly installed at each of the four corners of the reinforcing frame 10. A set of inclined tie system 3 is installed on each hanging ring 11.

[0030] During operation, the steel structure components to be assembled are placed on the lifting platform 8. The lifting system 4 is used to gradually raise the movable frame 2, which in turn raises the upper steel structure components to the required assembly height.

[0031] Once the movable frame 2 reaches the designated position, the inclined tie system 3 is connected to the lifting rings 11 at the four corners of the reinforcing frame 10 to stabilize and pull the movable frame 2 and the upper steel structure components from multiple inclined directions, preventing swaying during assembly.

[0032] The lower ends of the two sliding rods 9 on the same side are fixedly connected by the crossbar 12;

[0033] A support frame 13 is fixedly installed at the lower part of the bottom frame 1. A lifting system 4 is set between the support frame 13 and the crossbar 12. The lifting system 4 includes two sets of parallel lifting components. The lifting components include a pair of upper supports 14 and a pair of lower supports 15. One end of the upper support 14 is installed on the crossbar 12, and the other end is connected to one end of the lower support 15. The other end of the lower support 15 is installed on the support frame 13.

[0034] The two sets of lifting components are connected by a transmission rod 16, which is coaxial with the rotation axis of the upper support 14 and the lower support 15.

[0035] An operating lever 17 is provided between the two transmission rods 16. A handwheel 18 is coaxially fixed at one end of the operating lever 17. One transmission rod 16 near the handwheel 18 is rotatably connected to the operating lever 17. A nut is provided in the middle of the other transmission rod 16, and the nut is threadedly connected to the operating lever 17.

[0036] In use, turning the handwheel 18 drives the operating lever 17 to rotate. Since the operating lever 17 is threadedly engaged with the nut of one of the transmission levers 16 and is rotatably connected to the other transmission lever 16, it will push the two transmission levers 16 closer to each other, thereby increasing the hinge angle between the upper bracket 14 and the lower bracket 15, thus pushing the crossbar 12 upward, so that the sliding rod 9 slides smoothly along the connecting piece 7 of the bottom frame 1, thereby raising the lifting platform 8.

[0037] If it is necessary to lower the height, simply turn the handwheel 18 in the opposite direction. At this time, the threaded engagement generates a reverse driving force, which increases the distance between the operating levers 17, and the lifting assembly folds down, causing the crossbar 12 to descend.

[0038] The inclined cable system 3 includes a steel wire rope 19 fixedly connected to one of the lifting rings 11. An adjusting rod 20 is provided at the movable end of the steel wire rope 19. The adjusting rod 20 includes a pull ring connected to the steel wire rope 19. A screw is fixedly provided on the pull ring, and a fastening base 21 is threadedly connected to the screw.

[0039] The base 21 includes a base plate, a number of tie rods are fixedly installed on the upper surface of the base plate, a top plate is fixedly installed at the upper end of the tie rods, and a nut is rotatably installed in the middle of the top plate, and the nut is threadedly connected to the screw.

[0040] First, install the traction base 21 in a suitable position. Make mounting holes on the base plate of the traction base 21. Fix the traction base 21 to the ground with expansion bolts. Fix one end of the steel wire rope 19 to the lifting ring 11 at the corner of the reinforcement frame 10 and connect the other end to the pull ring of the adjusting rod 20 so that the steel wire rope 19 forms a preliminary oblique pulling path.

[0041] When the nut is turned clockwise, the screw extends along the axial direction of the nut, the tension of the wire rope 19 increases, and the pulling force on the movable frame 2 is enhanced.

[0042] The length of the wire rope 19 is adjustable. When lifting the movable frame 2, the length of the wire rope 19 can be adjusted in advance according to the preset lifting height.

[0043] An inner reinforcing rod 22 is fixedly installed in the middle of the crossbar 12. The top of the inner reinforcing rod 22 is fixedly connected to the reinforcing frame 10. A limiter 23 is fixedly installed on the upper surface of the bottom frame 1. A through hole is opened on the limiter 23, and the inner reinforcing rod 22 slides in the through hole.

[0044] When the horizontal bar 12 is driven to rise by the lifting system 4, the inner reinforcing bar 22 moves upward synchronously with the horizontal bar 12 and slides vertically along the through hole of the limiter 23; when it descends, the inner reinforcing bar 22 slides downward synchronously with the horizontal bar 12, always maintaining a sliding fit state within the through hole. The limiter 23 restricts the sliding direction of the inner reinforcing bar 22 through the through hole to prevent it from shifting laterally.

[0045] When using this utility model, the steel structure components to be assembled are placed on the lifting platform 8, and the movable frame 2 is gradually raised through the lifting system 4, which in turn raises the upper steel structure components to the required assembly height.

[0046] Once the movable frame 2 reaches the designated position, the inclined tie system 3 is connected to the lifting rings 11 at the four corners of the reinforcing frame 10 to stabilize and pull the movable frame 2 and the upper steel structure components from multiple inclined directions, preventing swaying during assembly.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
