Abstract

The invention relates to one set of auxiliary overturning device, in particular to one set of auxiliary overturning device for turbine base frame plate hoisting to solve the problems that according to a turbine base frame plate in the prior art, when gantry milling is carried out, an upper plane of the turbine base frame plate needs to be milled firstly, then the base frame plate is overturned, a bottom plane is milled, dangerousness is caused to an operator in the overturning process, the safety of the operator cannot be guaranteed, a workpiece is damaged, and work efficiency of the operator is reduced. The overturning device comprises two overturning mechanisms. Each overturning mechanism comprises an L-shaped tensioning block, a fixing and locking nut, an overturning frame, a cylinder and a plurality of ejecting pieces, wherein the cylinder is fixedly installed on the overturning frame, an external thread is machined at the other end of the cylinder, a first through hole is machined in one end of the L-shaped tensioning block, a second through hole is machined in the other end of the L-shaped tensioning block, the external thread end of the cylinder penetrates through the second through hole, and the fixing and locking nut is fixedly installed at the external thread end. The opening ends of the two overturning frames are opposite, and the auxiliary overturning device is used when the turbine base frame plate is machined.

Description

technical field [0001] The invention relates to a set of auxiliary turning devices, in particular to a set of auxiliary turning devices used for hoisting the base frame plate of a steam turbine. Background technique [0002] The base plate of the steam turbine is a cuboid steel plate. During the gantry milling process, it is necessary to mill the upper plane and then turn over and mill the bottom surface. In the past, this process was directly hoisted with a wire rope and turned over manually, which was dangerous to the operator and could not guarantee the safety of the operator. Safety, there is a possibility of bumping the processed surface, causing damage to the workpiece and reducing the work efficiency of the staff. Contents of the invention [0003] The present invention solves the problem that the steam turbine base plate in the prior art needs to mill the upper plane and then turn over and mill the bottom surface during the gantry milling process. During the turnin...
