[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] When installing a steel structure, a suspension device is often needed for hoisting and installation to facilitate the completion of the installation work. After the steel structure is lifted by an electric hoist, the steel wire rope is prone to swing. Due to the self-weight of the steel structure plus inertia, the swing amplitude of the steel wire rope continues to increase. If the steel wire rope is not maintained in time, a large swing amplitude is likely to cause the steel wire rope to break. After the steel wire rope breaks, the steel structure falls, not only is the steel structure prone to damage, but also it poses a safety hazard to the surrounding operators.

Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 This application will be further described in detail below.

[0023] The embodiments of this application disclose a suspension device for steel structure installation. Refer to Figure 1 and Figure 2A suspension device installed in a steel structure comprises a cross beam 1, a support column 2 is fixedly connected to the bottom of the cross beam 1, a bottom plate 3 is fixedly connected to the bottom of the support column 2, a universal wheel 13 is fixedly connected to the bottom of the bottom plate 3, a reinforcing plate 12 is fixedly connected to the surface of the bottom plate 3, one side of the reinforcing plate 12 is fixedly connected to the surface of the support column 2, an electric hoist 4 is movably connected to the surface of the cross beam 1, a steel wire rope 5 is wound around the surface of the electric hoist 4, a buffer mechanism 6 is arranged on one side of the support column 2, and an anti-fall mechanism 7 is arranged on the inner wall of the support column 2;

[0024] The anti-fall mechanism 7 includes a connecting plate 701, which is slidably connected to the inner wall of the support column 2, and one side of the connecting plate 701 is fixedly connected to a second connecting seat 702, and the inner wall of the second connecting seat 702 is rotatably connected to an anti-fall rod 703, and the inner cavity of the anti-fall rod 703 is slidably connected to an adjusting rod 704, and a positioning hole 705 is opened on the surface of the anti-fall rod 703, and the inner cavity of the adjusting rod 704 is movably connected to an elastic positioning block 706, and the elastic positioning block 706 is fixedly connected to the inner wall of the positioning hole 705. The suspension device forms a gantry through the crossbeam 1 and the support column 2, and the gantry ensures its support through the bottom plate 3. The anti-fall rod 703 can be mutually connected along the second connecting seat 702. After the steel structure is lifted up, the anti-fall rod 703 is rotated inwards, and the spacing between the two sets of anti-fall rods 703 is adjusted according to the volume of the steel structure to ensure that the steel structure can fall onto the anti-fall rod 703 when it falls accidentally. After adjustment, the anti-fall rod 703 is fixed in position by a fixing bolt. If the volume of the steel structure exceeds the protection range of the anti-fall rod 703, the adjusting rod 704 is extended, wherein the buffer mechanism 6 can assist in strengthening the protection of the steel structure, and then the steel structure is transported by the universal wheel 13, so that the suspension device can avoid the direct fall of the steel structure when the wire rope 5 breaks as much as possible through the anti-fall mechanism 7, thereby improving the safety of the suspended transportation of the steel structure.

[0025] Reference Figure 2 and Figure 3 A connecting hole 707 is provided on the surface of the connecting plate 701, and a second guide rod 8 is fixedly connected to the inner wall of the support column 2. The surface of the second guide rod 8 cooperates with the inner wall of the connecting hole 707. By setting the second guide rod 8, the connecting plate 701 can be regarded as the main structure for connecting the anti-fall mechanism 7 with the support column 2. The stability of the connection between the anti-fall mechanism 7 and the support column 2 is improved by the cooperation between the second guide rod 8 and the connecting hole 707.

[0026] Reference Figure 3, a buffer plate 9 is slidably connected to the surface of the second guide rod 8. A buffer layer 10 is fixedly connected to the top of the buffer plate 9, and a second spring 11 is fixedly connected to the bottom of the buffer plate 9. The second spring 11 is sleeved on the surface of the second guide rod 8, and one end of the second spring 11 is fixedly connected to the surface of the bottom plate 3. By providing the buffer plate 9 and the second spring 11, if the steel structure accidentally falls onto the anti-fall mechanism 7, a downward pressure will be generated. The connecting plate 701 and the buffer plate 9 will displace downward due to the downward pressure and compress the second spring 11. The second spring 11 absorbs the downward pressure, so as to buffer the steel structure and the anti-fall mechanism 7.

[0027] Refer to Figure 1 and Figure 4 , the buffer mechanism 6 includes a support plate 601. The number of support plates 601 is two. A first guide rod 602 is fixedly connected to the opposite sides of the two support plates 601. A buffer block 603 is slidably connected to the surface of the first guide rod 602. A first spring 608 is fixedly connected to the bottom of the buffer block 603. The first spring 608 is sleeved on the surface of the first guide rod 602, and one end of the first spring 608 is fixedly connected to the surface of the support plate 601. A first connecting seat 604 is fixedly connected to one side of the buffer block 603. A winding roller 605 is rotatably connected to the inner wall of the first connecting seat 604. An elastic rope 606 is wound around the surface of the winding roller 605. One end of the elastic rope 606 is fixedly connected to a fixing belt 607. By providing the elastic rope 606 and the fixing belt 607, the fixing belt 607 is sleeved on the surface of the steel structure, so that the steel structure and the buffer mechanism 6 are connected into one body through the fixing belt 607 and the elastic rope 606. On the one hand, the stability of the steel structure during transportation can be increased through the fixing belt 607. On the other hand, when the steel structure accidentally falls, it drives the fixing belt 607 and the elastic rope 606 to pull the buffer block 603, so that the buffer block 603 instantaneously presses downward along the surface of the first guide rod 602 and compresses the first spring 608, thereby buffering the force of the steel structure falling through the first spring 608, assisting the anti-fall mechanism 7 to avoid the steel structure directly falling to the ground as much as possible, and further enhancing the protection of the steel structure and the surrounding operators.

[0028] Refer to Figure 4 , a driving motor 609 is fixedly installed on the surface of the first connecting seat 604. The output end of the driving motor 609 passes through the inner cavity of the first connecting seat 604 and is fixedly connected to one side of the winding roller 605. By providing the driving motor 609 and the winding roller 605 to wind and unwind the elastic rope 606, while the electric hoist 4 hooks and lifts the steel structure, the driving motor 609 drives the winding roller 605 to unwind the elastic rope 606 to extend it, so that the fixing belt 607 is connected to the steel structure. While the electric hoist 4 lifts the steel structure, the driving motor 609 drives the winding roller 605 to wind up the line, assisting in lifting the steel structure.

[0029] Working principle: the anti-fall rods 703 can be unfolded along the second connecting seat 702 to facilitate the electric hoist 4 to fix and suspend the steel structure. After lifting, the anti-fall rods 703 are rotated inwards, and the distance between the two sets of anti-fall rods 703 is adjusted according to the volume of the steel structure. The drive motor 609 and the winding roller 605 are set to reel in and release the elastic rope 606. When the electric hoist 4 hooks the steel structure, the drive motor 609 drives the winding roller 605 to release and extend the elastic rope 606, so that the fixing belt 607 is connected to the steel structure. When the electric hoist 4 lifts the steel structure, the drive motor 609 drives the winding roller 605 to reel in the wire to assist in lifting the steel structure. The anti-fall rod 703 rotates to the range of the steel structure volume and is fixed in position by the fixing bolt. If the volume of the steel structure exceeds The adjusting rod 704 is extended beyond the protection range of the anti-fall rod 703, and then the steel structure is transported by the universal wheel 13. The steel structure is connected to the buffer mechanism 6 as a whole by the fixing belt 607 and the elastic rope 606. On the one hand, the fixing belt 607 can increase the stability of the steel structure during transportation. On the other hand, when the steel structure falls accidentally, the fixing belt 607 and the elastic rope 606 are driven to pull the buffer block 603, so that the buffer block 603 is instantly pressed down along the surface of the first guide rod 602 and squeezes the first spring 608, so that the force of the steel structure falling is buffered by the first spring 608. Therefore, the suspension device can avoid the direct fall of the steel structure when the wire rope 5 breaks through the anti-fall mechanism 7, thereby improving the safety of the steel structure suspension transportation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
