[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0028] Sheet metal parts often need to be turned around during the bending and splicing process, and the angles need to be changed constantly during splicing. Especially for large components, manual handling can easily cause problems such as scratches and deformation of the workpieces. If a sling is used, the existing sling cannot adapt well to the sheet metal parts, has poor applicability, and cannot be well applied to different panels. In view of this point, a sling suitable for sheet metal parts is designed, and the specific structure is as follows.

[0029] See also Figures 1 to 4 The large sheet metal hanger includes two frame frames 1, two extension plates 2 and a net bag portion 3 located outside the two extension plates 2. The net bag portion 3 is used to hold the sheet metal. The bottom center of the frame frame 1 is connected to the top of the extension plate 2, and a hanging portion 4 is connected between the tops of the two frame frames 1.

[0030] See also Figures 1 to 4 In order to adjust the containing area, a winding shell 5 is installed on the opposite side of the two extension plates 2. A notch is provided at the bottom of the winding shell 5. A winding rod 6 is rotatably connected to the inner center of the winding shell 5. In order to rotate the winding rod 6, a rotating motor 7 is installed on one side of the winding shell 5. The driving end of the rotating motor 7 is connected to the end of the winding rod 6 through a coupling.

[0031] The outer periphery of the winding rod 6 is wound around the corresponding end of the corresponding net bag part 3. The net bag part 3 is designed to pass through the slot. Therefore, when the rotating motor 7 is started, it will drive the winding rod 6 to wind and unwind the net bag part 3, thereby realizing the adjustment of the containing area of ​​the net bag part 3.

[0032] See also Figure 1 , Figure 3 and Figure 4 In order to adjust the storage area, an adjustment straight tube 9 is provided between the two adjacent sides of the two frames 1. The two sides of the adjustment straight tube 9 are designed to be open, and a side-connected straight rod 8 is provided at the opening. The side-connected straight rod 8 and the opening are designed to be adapted and form an anti-rotation design. A connecting portion is provided at the end of the side-connected straight rod 8, and the connecting portion is fixed to the frame 1 by bolts. In order to drive the side-connected straight rod 8, adjustment is performed. For adjustment, an electric device such as a hydraulic rod or a telescopic rod can be selected. Although the use of an electric device can play a role in driving movement, the telescopic space margin is required for the telescopic movement of the electric device such as the hydraulic rod or the telescopic rod. For example, if it is a hydraulic rod, there must be enough space at the bottom to store the length of the fixed portion of the hydraulic rod, which leads to a waste of space and easily increases the volume of the device. In view of this point, another adjustment structure is designed, and the specific structure is as follows;

[0033] A cavity is provided at the center of the adjusting straight tube 9, and a plurality of bevel gears 11 are provided on the inner circumference of the cavity. The plurality of bevel gears 11 are selected according to actual conditions, and three bevel gears are preferably provided in this design. The plurality of bevel gears 11 are meshed with each other, and the centers of the bevel gears 11 on both sides are connected with adjusting screws 10, and the portion where the adjusting screws 10 penetrate the adjusting straight tube 9 is designed to be rotatably connected, and a threaded hole is provided at the center of the side connecting straight rod 8, and the threaded hole and the adjusting screw 10 are designed to be threadedly connected;

[0034] In order to achieve driving, a driving motor 12 is installed at the top center of the adjusting straight tube 9. The driving end of the driving motor 12 passes through the adjusting straight tube 9 and is connected to the corresponding bevel gear 11 through a coupling, so that when the bevel gear 11 in the center rotates, multiple bevel gears 11 can rotate synchronously.

[0035] In order to assist stability, a hook portion 13 is provided on the outer side of the edge connecting straight rod 8 and the adjustment straight tube 9, and a secondary blocking net can be hung between the hook portion 13 and the outer bottom of the net bag portion 3. The secondary blocking net can be designed with specific elasticity and have hooks at both end shells to achieve hanging and fixing.

[0036] The above-mentioned components and electrical equipment are all existing technologies or existing feasible technologies. The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0037] How it works

[0038] When the large sheet metal lifting device is needed, the driving motor 12 is started according to the size of the sheet metal, driving the bevel gear 11 to rotate, so that the bevel gear 11 on the side rotates, so that the two adjusting screws 10 rotate synchronously, and due to the adaptation and limiting effect of the opening of the side connecting straight rod 8 and the adjusting straight tube 9, the position of the side connecting straight rod 8 is further moved to the required spacing;

[0039] Then start the two rotating motors 7 to drive the two winding rods 6 to rotate, wind or unwind the net bag part 3, adjust the holding range of the net bag part 3, place the sheet metal parts inside the net bag part 3, hang the hanging part 4 on the external lifting equipment, and then use the auxiliary blocking net for mobile transportation.
