Levelling device for large shell type component

Abstract

The invention discloses a levelling device for a large shell type component. A pedestal is welded above a supporting seat; a cushion block is positioned above the supporting seat; a thrust oblique body is positioned in a groove of the pedestal and is provided with a horizontal hole; the surface of the cushion block is provided with a lower semicircular groove; a power screw sequentially passes through the lower semicircular groove of the cushion block and the horizontal hole of the thrust oblique body; a lifting oblique body is positioned above the thrust oblique body; a rubber cushion is fixedly arranged at the upper surface of the lifting oblique body through a bolt II; a pressing plate passes through the rubber cushion body and is used for covering the upper portion of the pedestal; an upper semicircular groove of the pressing plate is capable of covering the upper portion of the power screw. According to the levelling device disclosed by the invention, a lifting platform pushed by a screw is designed, and the screw is applied with a torque by two mutually-matched oblique bodies so that stable lifting of the lifting platform can be realized. The levelling device is capable of satisfying levelling of a large shell, also small in input torque, convenient to operate, good in lifting stability, and capable of improving the levelling efficiency for the large shell and shortening the working time for levelling the shell.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a leveling device for large casing parts. Background technique [0002] The assembly of large-scale boxes is generally based on large-scale shell parts, and other parts are installed in the shell. Due to the large size, it is necessary to cooperate with the crown block during the assembly process and level it by adding shims. This method Not only is it inconvenient to operate, it takes a long time for leveling, but it also has the disadvantage of being unstable when lifting. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a leveling device for large casing parts. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a leveling device for large shell parts, which is characterized in that it includes a support seat, a base, a pressure plate, a bolt one, a ru...
