Abstract

The invention discloses a special splicing tool for a critical turboset low-pressure cylinder. The special splicing tool for the critical turboset low-pressure cylinder comprises an adjustment device used for adjusting the relative angle of the connecting position of a low-pressure cylinder lateral plate and a low-pressure cylinder end plate, and a pressing plate used for adjusting the height of a horizontal end surface at the connecting position of the low-pressure cylinder lateral plate and the low-pressure cylinder end plate. The adjustment device comprises a supporting part perpendicularly fixed to the inner side surface of the low-pressure cylinder lateral plate and an adjustment part perpendicularly connected with the supporting part, wherein one end of the adjustment part is fixedly connected with the low-pressure cylinder lateral plate, the other end of the adjustment part is in sliding connection with the supporting part, and the adjustment part and the movable end of the supporting part are fixed through a fastener. The special splicing tool for the critical turboset low-pressure cylinder can shorten the installation time of equipment, improve installation accuracy, overcome the defects of a large on-site installation tool, and reduce waste of labor resources and installation materials.

Description

technical field [0001] The invention relates to the field of splicing large cylinders, in particular to a special tool for splicing low-pressure cylinders of critical steam turbines. Background technique [0002] A steam turbine is a rotary power machine that converts the energy of steam into mechanical work, also known as a steam turbine. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. It is also possible to use the exhaust steam or intermediate steam extraction of the steam turbine to meet the heating needs of production and life. During the installation of the steam turbine unit, the accuracy of the misalignment of the horizontal middle face of the low-pressure cylinder and the accuracy of the angle between the side plate and the end plate are relatively high. Installation posed great difficulties. Contents of the invention [0003] The technical problem to be solved by the pre...
