Embodiment 3

[0046] This example discloses a flexible lifting device suitable for large-scale products. As a preferred embodiment of the present invention, that is, in Example 1, the frame body includes a load-bearing base plate 2.1 and side panels arranged at both ends of the load-bearing base plate 2.1. The baffle plate 2.2 and the side baffle plate 2.2 are detachably connected to the load-bearing bottom plate 2.1 through the connecting bolt 2.3. The bracket 2 of this technical solution adopts the matching structure of the load-bearing base and the side baffle 2.2, wherein the side baffle 2.2 can effectively prevent the product from rolling down from the load-bearing base 2.1, which improves the reliability of the technical solution during use. In addition, a detachable connection is set between the load-bearing base and the side baffle 2.2, and the side baffle 2.2 can be removed from the bearing before the frame of the aircraft body is placed and before the lifting unit is disassembled. ...

Abstract

The invention relates to the technical field of mechanical assembly, in particular to a flexible lifting device suitable for large products and a lifting method. The flexible lifting device comprises a control cabinet, a display unit and at least one lifting unit; each lifting unit comprises a lifting mechanism and a bracket; each lifting mechanism comprises two same lead screw lifters and a power device for controlling the two lead screw lifters to synchronously ascend or descend; a frame body is provided with two sensing assemblies in one-to-one correspondence with the two lead screw lifters; and each sensing assembly comprises a displacement sensor and a pin shaft sensor which are electrically connected with an electrical control system. According to the technical scheme, an electric appliance control system is matched with the power device, automatic ascending or descending of the lifting unit is achieved, the mode that a large product is lifted manually is replaced, the working intensity of operators is effectively reduced, the bearing capacity and the lifting height can be observed through a displayer, a powerful basis is provided for adjusting the lifting height of a bracket unit, and a good foundation is laid for stably lifting the product.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a flexible lifting device and a lifting method suitable for large-scale products. Background technique [0002] Large-scale product assembly, manufacturing or transportation must be parked stably and reliably to ensure product stability and safety when large components are installed or when a large number of operators board the product for operation, so multi-point / surface support is adopted. As the assembly or manufacturing process advances, the installation materials continue to increase, the product weight continues to increase, the center of gravity of the product changes continuously, and the stress on each support point also changes accordingly. The product is prone to structural deformation or stress damage. [0003] At present, traditional bracket-type lifting tooling is mainly used for product support and posture adjustment, but the traditional bracket-type l...
