Can be to special-shaped panel, slide the auxiliary stay bar with the outstanding part below of special-shaped panel in order to play the effect of stable transfer in-process panel, but need not add whole purlin after setting up like this again, so simplified the structure of bracket, reduced the material of using of bracket to set up like this also more nimble, can adjust the position of auxiliary stay bar according to the condition of different special-shaped panels.
The panel is not direct with horizontal truss or the contact of longitudinal truss, but with rubber spare contact, can avoid like this the transfer bracket to appear the damage defect such as panel surface fish tail that the tiny displacement of horizontal and vertical truss on panel surface and the transfer bracket caused when transferring panel, transfer panel, and contact with rubber spare has increased frictional force, also makes the transfer process more stable.
The auxiliary trusses on the adjacent transverse trusses are arranged in a non-parallel mode before the transfer (namely, one side rotates to the position where the auxiliary trusses cannot rotate, and the other side rotates to the position where the auxiliary trusses cannot rotate), so that after the plate is placed on the transfer bracket, the two auxiliary trusses on the adjacent transverse trusses are arranged in a V shape or triangle, and after the plate is placed on the auxiliary trusses, the plate is very stable during the transfer (the situation on the longitudinal trusses is similar) by matching with the rubber blocks or rubber balls on the auxiliary trusses. The surface of the longitudinal and transverse trusses, which is opposite to the plate, is fixedly provided with rubber balls/blocks, so that on one hand, the friction force between the longitudinal and transverse trusses and the plate is increased, and the safety during lightnings is ensured, and on the other hand, the arrangement of the rubber blocks/rubber balls is adopted, so that the plate is not in direct contact with the longitudinal and transverse trusses made of hard materials, but is in contact with the rubber blocks/rubber balls made of flexible materials, and scratches and the like caused by contact of the material and the longitudinal and transverse trusses on the lightnings brackets are avoided.
The auxiliary nylon belt is arranged at the edge of the whole transfer bracket (arranged on the transverse truss or the longitudinal truss at the outermost side), when the transfer is carried out on the plate with the conventional shape, the auxiliary nylon belt can be attached to the side end face of the plate in a manner of assisting in maintaining the stable effect of the transfer process, the length of the auxiliary nylon belt is slightly longer than that of the truss (the transverse truss or the longitudinal truss) connected with the auxiliary nylon belt, so that the auxiliary nylon belt which is not in a tight state can be attached to the side end face of the plate even though the friction section of the auxiliary nylon belt is realized before the transfer starts, and the auxiliary nylon belt can play a role of supporting the plate when the plate moves in the transfer process, so that the safety and stability of the transfer process are maintained.
