The beneficial effects are: by setting a clamp at the bottom of the steel cable and incorporating the workpiece to be clamped into the steel structure, precise positioning is achieved through the cooperation of the clamp and the clamping hole; and by setting a positioning sleeve at the bottom of the crossbeam of the lifting device frame and a positioning pin at the top of the hanger, the steel structure will not sway due to wind after being lifted to a high altitude.

[0003] Based on the aforementioned document, lifting devices are indispensable equipment in steel structure construction, used to lift steel structure components to a designated height for installation or assembly. However, existing steel structure lifting devices have some shortcomings in their use:

[0004] On the one hand, it is difficult to balance the mobility and stability of the device. Although some devices are equipped with casters for easy movement, they are prone to displacement due to the weight and swaying of the steel structure during lifting operations, affecting construction safety. On the other hand, the effect of fixing the steel structure to prevent it from falling is not good. Traditional fixing methods are mostly single mechanical clamps. During the lifting process, the steel structure may loosen or even fall due to vibration, swaying, etc., posing a significant safety hazard. Therefore, this utility model provides a steel structure lifting device with a magnetic anti-fall structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A steel structure lifting device with a magnetic anti-scattering structure includes a base 1. Multiple sets of self-locking casters 2 are installed at the bottom of the base 1. A stabilizing component 3 is provided on the surface of the base 1. A symmetrical column 4 is installed on the top of the base 1. A support plate 5 is fixedly connected to the top of the column 4. A lifting plate 7 slides on the surface of the column 4 via a lifting component 6. A magnetic anti-scattering mechanism 8 is provided on one side of the lifting plate 7. The magnetic anti-scattering mechanism 8 includes:

[0027] The anti-scattering assembly 81 includes a placement plate 811 installed on one side of the lifting plate 7 and a drive cylinder 812 installed on the other side of the lifting plate 7. The inner wall of the placement plate 811 is fixedly connected to a symmetrical limiting rod 813. The surface of the limiting rod 813 is slidably connected to a symmetrical sliding plate 814. A connecting block 815 is installed on the top of the sliding plate 814. An anti-scattering clamp 816 is fixedly connected to the top of the connecting block 815. One side of the drive cylinder 812 is fixedly connected to the outer side of the sliding plate 814 through a piston rod.

[0028] Linkage component 82 is located inside the sliding plate 814 and is used to link the two sets of sliding plates 814 to achieve synchronous sliding.

[0029] The magnetic suction component 83 is located inside the placement plate 811 and is used to help stabilize the steel structure.

[0030] The base 1 is made of high-strength Q345 steel; the column 4 and the support plate 5 are made of Q355 high-strength structural steel; and the lifting plate is made of 45 medium carbon steel.

[0031] The top of the placement plate 811 is provided with a symmetrical sliding groove, and the connecting block 815 slides on the inner surface of the sliding groove; the inner side of the anti-scattering clamp plate 816 is equipped with an anti-slip pad.

[0032] The drive cylinder 812 uses a compact cylinder from SMC's CJP series, model CJP25-50-S.

[0033] In this embodiment, the linkage assembly 82 includes a linkage toothed plate 821 fixedly installed inside the sliding plate 814 and a linkage gear 822 rotatably installed at the bottom of the inner cavity of the placement plate 811. The surface of the linkage gear 822 meshes with one side of the linkage toothed plate 821.

[0034] In this embodiment, the magnetic suction assembly 83 includes a mounting plate 831 installed at the bottom of the inner cavity of the placement plate 811, and a magnetic suction plate 832 is provided on the top of the mounting plate 831, with the top of the magnetic suction plate 832 extending through to the outside of the placement plate 811.

[0035] The magnetic plate 832 is an electromagnetic plate structure. Its core components are an iron core made of high-purity electrical silicon steel sheets and a winding coil made of high-strength enameled copper wire. It is precision-machined, with a high lamination factor and good insulation of the iron core. The winding coil is precisely wound, insulated and moisture-proof. It has a stainless steel shell and thermally conductive filler. The output end has a high protection level. Its magnetic force can be adjusted by current. The attraction force is continuously adjustable from 500 to 5000N. It has a fast response speed, stable electrical performance, and good heat dissipation. It is controlled by a controller, which is installed at the bottom of the placement plate 811.

[0036] The anti-scattering component 81 in the magnetic anti-scattering mechanism 8, under the action of the driving cylinder 812, can drive the sliding plate 814 to slide along the limiting rod 813, so that the anti-scattering clamp 816 clamps and fixes the steel structure. The linkage component 82, through the meshing of the linkage tooth plate 821 and the linkage gear 822, can ensure that the two sets of sliding plates 814 slide synchronously, ensuring the stability of the clamping. The magnetic suction plate 832 of the magnetic suction component 83 can attract the steel structure, further enhancing the anti-scattering effect. The dual fixing method greatly improves the safety of the steel structure during the lifting process.

[0037] In this embodiment, the lifting assembly 6 includes a reduction motor 61 installed on the top of the support plate 5. One end of the output shaft of the reduction motor 61 is fixedly connected to a rope roller 62 via a coupling. A steel wire rope 63 is sleeved on the surface of the rope roller 62. One end of the steel wire rope 63 is fixedly connected to a hook 64, which is connected to the top of the lifting plate 7.

[0038] The geared motor 61 is a SEW-EUROMOTORS R-series helical geared motor, specifically model R77DT90L4 / BMG / HF / TF.

[0039] In this embodiment, a symmetrical support rod 9 is installed at the bottom of the support plate 5, and the surface of the support rod 9 is slidably connected to the inside of the lifting plate 7.

[0040] The support rod 9 can limit the up and down sliding of the lifting plate 7.

[0041] In this embodiment, the stabilizing component 3 includes a control block 31 rotatably mounted on the top of the base 1. The control block 31 is internally threaded with a stabilizing screw 32. The bottom end of the stabilizing screw 32 is fixedly connected to a stabilizing plate 33. The top of the stabilizing plate 33 is fixedly connected to a symmetrical positioning rod 34. The surface of the positioning rod 34 is slidably connected to the interior of the base 1.

[0042] The bottom of the stabilizing plate 33 is also equipped with an anti-slip pad; the positioning rod 34 is used to limit the up and down sliding of the stabilizing plate 33.

[0043] A control panel is installed on the top of the base 1, and the control panel is electrically connected to the controllers of the geared motor 61, the drive cylinder 812, and the magnetic plate.

[0044] By setting the stabilizing component 3, rotating the control block 31 can drive the stabilizing screw 32 to move downward, thereby making the stabilizing plate 33 contact the ground. Combined with the positioning function of the positioning rod 34, it can effectively enhance the stability of the device during operation and prevent the device from shifting due to shaking. At the same time, the self-locking caster 2 facilitates the movement of the device, taking into account both mobility and stability.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] Before starting work, the operator can push the device to the designated construction position. After arriving at the position, first lock the self-locking caster 2 to initially fix the device. Then, rotate the control block 31 in the stabilizing component 3. Since the control block 31 is threadedly connected to the stabilizing screw 32 and the positioning rod 34 restricts the rotation of the stabilizing plate 33, the stabilizing screw 32 will drive the stabilizing plate 33 to move downward until the stabilizing plate 33 is in close contact with the ground, thereby enhancing the stability of the device during operation and preventing the device from shifting due to the weight and shaking of the steel structure during subsequent lifting operations.

[0047] During operation, the steel structure to be lifted is placed on the placement plate 811 of the magnetic anti-scattering mechanism 8. Then, the drive cylinder 812 is started through the control panel. The piston rod of the drive cylinder 812 pushes the sliding plate 814 on one side to slide along the limiting rod 813 on the inner wall of the placement plate 811. Because the linkage tooth plate 821 on the inner side of the sliding plate 814 meshes with the linkage gear 822 at the bottom of the inner cavity of the placement plate 811, the movement of the sliding plate 814 on one side will drive the sliding plate 814 on the other side to slide synchronously through the linkage gear 822, so that the two sets of anti-scattering clamps 816 move closer to each other and clamp and fix the steel structure. At the same time, the magnetic suction plate 832 inside the placement plate 811 generates an adsorption force on the steel structure, further enhancing the fixing effect of the steel structure, forming a double fixation, and effectively preventing the steel structure from scattering during the lifting process.

[0048] Subsequently, the reduction motor 61 in the lifting assembly 6 is started through the control panel. The output shaft of the reduction motor 61 drives the rope roller 62 to rotate through the coupling. The rotation of the rope roller 62 realizes the winding and unwinding of the wire rope 63. The wire rope 63 drives the lifting plate 7 to slide along the support rod 9 at the bottom of the column 4 and the support plate 5 through the hook 64. The support rod 9 plays a guiding and supporting role for the lifting plate 7, ensuring that the lifting plate 7 remains stable during the lifting process, thereby smoothly lifting the steel structure to the specified height.

[0049] After the lifting is completed, the piston rod of the drive cylinder 812 is retracted by controlling the control panel, which drives the sliding plate 814 and the anti-scattering clamp 816 to reset, releasing the clamp on the steel structure. At the same time, the magnetic suction function of the magnetic suction plate 832 is turned off, and the steel structure can be removed from the placement plate, completing one lifting operation.
