[0025] Embodiment, please refer to the drawings Figures 1-4 A steel structure lifting support device, the steel structure lifting support device includes a lifting frame 10, the lifting frame 10 is inverted U-shaped structure. Lifting frame 10 area is installed with lifting assembly 20, and lifting frame 10 is installed with lifting plate 30 connected with lifting assembly 20.

[0026] The bottom of lifting plate 30 is provided with two symmetrical sliding grooves 31, and a cavity 32 is arranged between the two sliding grooves 31. The clamping mechanism 50 is installed on the lifting plate 30, the clamping mechanism 50 includes two first lead screws 53 rotatably connected to the two sliding grooves 31 and penetrating into the cavity 32, a clamping block 51 symmetrically and slidingly connected to the two first lead screws 53, a first motor 52 installed at the top of the cavity 32, a drive bevel gear 54 located inside the cavity 32 and connected with the output shaft of the first motor 52, and two driven bevel gears 55 connected with one end of the inner side of the two first lead screws 53 and meshed with the drive bevel gear 54.

[0027] In this embodiment, it should be noted that the bottom of the lifting frame 10 of the device is provided with an opening, so that the lifting plate 30 can be lowered to the bottom through the lifting assembly 20, and then the clamping mechanism 50 can clamp and lift the steel structure on the ground, without lifting the steel structure, saving time and effort, and the device can simultaneously lift two steel structures, effectively improving the work efficiency.

[0028] In addition, it should be noted that the electrical components of the device are externally connected to the power supply and electrically connected to the conventional controller.

[0029] Specifically, please refer to the accompanying drawings Figure 2 The two sides of the lifting frame 10 are provided with lifting grooves. The lifting assembly 20 comprises a second lead screw 22 rotatably connected in the two lifting grooves, a nut seat 23 symmetrically installed on the two second lead screws 22, a drive wheel 24 installed on the top of the two second lead screws 22, a transmission belt 25 sleeved on the two drive wheels 24, a second motor 21 installed on the top of the lifting frame 10 and having an output end connected with one of the second lead screws 22, and two nut seats 23 connected with the lifting plate 30.

[0030] In this embodiment, it should be noted that through the operation of the second motor 21, the synchronous rotation of the two second lead screws 22 can be realized by cooperating with the drive wheel 24 and the transmission belt 25, and then the stable lifting of the lifting plate 30 driven by the two nut seats 23 is realized.

[0031] Specifically, please refer to the accompanying drawings Figure 1 The two bottom sides of the lifting frame 10 are provided with moving wheels 40.

[0032] In this embodiment, it should be noted that the moving wheels 40 can facilitate the movement of the device, so as to be moved to a suitable area.

[0033] Specifically, please refer to the accompanying drawings Figure 1 The clamping block 51 is of Z-shaped structure, and when the nut seat 23 is located at the bottommost position of the lifting groove, the bottom horizontal height of the clamping block 51 is consistent with the bottom horizontal height of the moving wheel 40.

[0034] In this embodiment, it should be noted that when the lifting plate 30 is located at the bottommost position, the height of the clamping block 51 can ensure the clamping of the steel structure at the bottommost position.

[0035] Specifically, please refer to the accompanying drawings Figure 3 The two clamping blocks 51 are embeddedly installed with rubber pads 56 on the side close to each other.

[0036] In this embodiment, it should be noted that the rubber pads 56 can increase the frictional resistance to ensure the clamping effect of the steel structure.

[0037] Specifically, please refer to the accompanying drawings Figure 3 The two sides of the lifting plate 30 are provided with two sets of clamping mechanisms 50.

[0038] In this embodiment, it should be noted that the two sets of clamping mechanisms 50 can effectively ensure the clamping effect of the steel structure on both sides, so as to prevent the steel structure from falling during lifting and avoid danger.

[0039] Specifically, please refer to the accompanying drawingsFigure 2 A positioning nail 60 is installed through the center of the lifting plate 30, and the positioning nail 60 and the lifting plate 30 are connected by internal and external threads.

[0040] In this embodiment, it should be noted that the device is prone to tilting when lifting the steel structure because the steel structure is not light, at which time the positioning nail 60 needs to be rotated and turned into the ground, thereby stabilizing the lifting frame 10 and increasing stability. Meanwhile, the device preferably ensures that two steel structures are simultaneously lifted.

[0041] The specific operation mode of the device is as follows:

[0042] In use, the device is first fixed at a suitable position by the positioning nail 60, and then the steel structure is placed in position. The second motor 21 is started, and the driving wheel 24 and the transmission belt 25 are driven to synchronously rotate the two second lead screws 22, and the two nut seats 23 drive the lifting plate 30 to descend, so that the lifting plate 30 descends to the top of the steel structure. Then the first motor 52 is started, the driving bevel gear 54 is engaged with the driven bevel gear 55 to drive the two first lead screws 53 to synchronously and oppositely rotate, so that the two clamping blocks 51 are close to each other to clamp the steel structure. Then the second motor 21 is operated again to lift the steel structure with the lifting plate 30.

[0043] The device has been described above in conjunction with the drawings, and it is obvious that the specific implementation of the device is not limited by the above mode. As long as the method concept and technical solution of the device are adopted for non-essential improvements or the concept and technical solution of the device are directly applied to other occasions without improvement, they are within the protection scope of the device.
