Background technique

In the process of mechanical assembly, for large and high-weight cylindrical products, operators are also required to assemble various functional components such as various cables, conduits, and small finished products inside and outside. Therefore, it is required that the large and high-weight cylindrical finished product cannot directly contact the ground, but be lifted off the ground by other devices to a certain height until the optimum installation height for the operator is met. Therefore, the device for lifting it must have functions such as high strength and good flexibility. The current conventional method and tooling is to lift the large/high-weight finished main structure from the structure installation area to the small cables, conduits, and finished products area by a sky crane, and then the operator uses N ordinary brackets and manually Raise the ordinary brackets slowly, and then carry out the lifting work one by one. Although the above-mentioned method can also satisfy the installation work of the large/high-weight cylindrical finished product, it also shows some room for improvement. One is that the previous bracket tray was manually lifted by the operator. Due to the influence of the service life and the weight of the bracket itself, two operators are required to operate a lifting screw to complete this work. Not only increases the difficulty of the work, but also increases the intensity of the work. The 2nd, whole lifting work needs more than two operators to finish, therefore also increased the number of work virtually, and work efficiency is not high.
