The end of the assembly end block 3 away from the assembly frame 2 is provided with a lifting hole 8. The lifting hole 8 allows the operator to lift the blade through this device, thereby improving work efficiency. Each set of assembly end blocks 3 is provided with a mounting plate 6 below. One side of the mounting plate 6 is installed corresponding to the bottom of the assembly end block 3. One side of the mounting plate 6 is fixedly connected to the assembly end block 3. The mounting plate 6 is provided with multiple sets of assembly holes 9. The mounting plate 6 and the assembly holes 9 allow the assembly end block 3 to be fitted with pulleys, thereby making it easy for the operator to transfer the blade.
[0020] A support assembly 4 is provided above the supporting beam 1. The support assembly 4 includes two sets of side support brackets 41, which are located on one side above both ends of the supporting beam 1. Each set of side support brackets 41 includes a mounting base plate 411 located above the supporting beam 1. The mounting end of the mounting base plate 411 is fixedly connected to the supporting beam 1. A support frame 412 is provided above the mounting base plate 411. The support frame 412 is T-shaped, and its lower end is fixedly connected to the mounting base plate 411. The T-shaped design of the support frame 412 enhances the strength of the side support brackets 41, thereby better supporting the blades. A top plate 413 is provided above the support frame 412. The top plate 413 is connected to the support... The first support frame 412 is fixedly connected. Multiple main support frames 42 are arranged between the two sets of side support frames 41.

A second support frame 422 is arranged above the second mounting plate 421. The second support frame 422 is H-shaped, and one lower end of the second support frame 422 is fixedly connected to one side of the second mounting plate 421. The H-shaped arrangement of the second support frame 422 enhances the overall strength of the main support frame 42, allowing for better cooperation with the side support frames 41 and main support frames 42 to support the blade. Multiple sets of reduction holes 10 are provided on the second support frame 422. The multiple sets of reduction holes 10 allow for adjustments to the main support frame 42 without affecting its strength. Weight reduction is implemented to lower the overall weight of the device, facilitating disassembly and assembly by the operator. A top plate 423 is installed above the second support frame 422, and the second support frame 422 is fixedly connected to the top plate 423. Load-bearing braided straps 43 are installed on both sides of the main support bracket 42. Grooves 11 are provided on one side of each set of top plates 413 and on both sides of the second top plate 423.

One end of the braided belt 43 is installed correspondingly to the adjusting buckle on the adjusting seat 44. The braided belt 43 supports the blade, and the adjusting seat 44 allows for adjustment of the braided belt 43. This enables the braided belt 43, in conjunction with the side support bracket 41 and the main support bracket 42, to support blades of different sizes. The braided belt 43 better conforms to the outer contour of the main blade, ensuring the stability of the main blade during transport. The overall structure of this device is simple. The supporting beam 1 and the support assembly 4 work together to stably support the main blade. At the same time, the support assembly 4 allows the device to support main blades of different sizes, facilitating quick transport of the main blade by the operator.Improve operator efficiency in handling the blades.
[0021] In this embodiment, the operator first fixes the assembly frame 2 with quick-release sleeve 5 to both ends of the supporting beam 1. Then, the operator installs the assembly end block 3 with mounting plate 6 to the assembly frame 2 using quick-release pin 7. Next, the operator installs the two sets of side support brackets 41 at the positions above both ends of the supporting beam 1. At the same time, multiple sets of main support brackets 42 are assembled between the two sets of side support brackets 41. Then, the operator assembles the adjusting seat 44 on both sides of each set of main support brackets 42 above the supporting beam 1. Finally, the operator installs the mounting end of the braided strap 43. Install the device with the groove 11 on the side support bracket 41 and the main support bracket 42, then assemble the adjusting end of the support braided belt 43 with the adjusting buckle on the adjusting seat 44. Finally, adjust the mechanical energy of the support braided belt 43 according to the size of the blade to be supported by the adjusting seat 44, so that the support braided belt 43, together with the side support bracket 41 and the main support bracket 42, can stably support the blade, thereby completing the assembly operation of this device. The operator can assemble multiple sets of this device according to the length of the main blade, thereby adapting to the support operation of main blades of different lengths.
