hydraulic lifting mechanism

Abstract

The invention discloses a hydraulic lifting mechanism, comprising: a chassis, a lifting mechanism, an end adjustment mechanism and a holding mechanism. The hoisting mechanism is installed on the chassis, and the hoisting mechanism lifts in the vertical direction. The end adjustment mechanism is installed on the top of the lifting mechanism, and the end adjustment mechanism has four axial rotation mechanisms, and the rotating shafts of the four axial rotation mechanisms are not parallel to each other. The holding mechanism is installed on the top of the end adjustment mechanism, and the holding mechanism holds the workpiece. The hydraulic lifting mechanism of the present invention provides a two-stage lifting mechanism and a rotating mechanism with four shafts that are not parallel to each other, combined with a chassis with wheels, the workpiece held by the hydraulic lifting mechanism has sufficient flexibility and can be rotated at any angle It is fixed at any position within the maximum ceiling of the hoisting mechanism.

Description

technical field [0001] The invention relates to the field of steel structure manufacturing, and more specifically relates to a hydraulic lifting mechanism for lifting steel structure workpieces. Background technique [0002] In the production process of steel structure engineering, it is necessary to install prefabricated parts (also called workpieces) that are either profiles or plates on the main frame, and then welded and fixed. During the installation process, there are generally two methods for how to move these parts to the corresponding height position: the first method is for structural parts with large size and heavy weight. bit way. For the assembly of small structural parts with a weight of less than 100KG, mechanical hoisting is often used if it is at a high altitude. For the assembly of structural parts at a low altitude below three or four meters, most of them use a working group composed of three or five people to carry the structural parts with the help of ...

Problems solved by technology

The characteristic of this mode of operation is that although it is maneuverable and flexible, it has a large number of variables and a high risk factor, because it is in contact with metal and fire (flame spatter generated during welding, the temperature can reach above 1500 °), a little carelessness will cause accidents due to action. Inconsistency or inability to hold the parts so that the parts slip from the shoulders and hands and hurt the legs and feet
