Abstract

The invention provides a fast opening device for a large-scale coupling flange plate and a fast opening method of the large-scale coupling flange plate, and belongs to disassembling tools of coupling flanges of flange end face keys. The fast opening device for the large-scale coupling flange plate comprises a connecting key matrix, a locating pin, an adjusting shim, a hollow hydraulic cylinder, a hydraulic fast connector, a hand-operated change-over valve and a movable hydraulic pump station. The fast opening device for the large-scale coupling flange plate is characterized in that an installation hole is milled in the matrix of the flange end face key of a coupling flange, a locating hole is formed in the bottom portion of the flange end face key of the coupling flange, the hollow hydraulic cylinder is installed through the locating pin, and the hydraulic cylinder is connected with the movable hydraulic pump station through the hydraulic fast connector. The fast opening device for the large-scale coupling flange plate has the advantages that under large acting force of the hollow hydraulic cylinder driven by a power hydraulic pump, the coupling flange plate can be directly and greatly opened from the inner portion, and the large-scale coupling flange plate end face can be opened conveniently. The fast opening device for the large-scale coupling flange plate is simple in structure, convenient to dismount and install, strong in dismantling capability, and small in work labor intensity.

Description

technical field [0001] The invention belongs to a tool and a method for disassembling and assembling a flange plate of a key shaft coupling on a flange end face, in particular to a quick-opening large-scale coupling flange device and a quick-opening method thereof. Background technique [0002] The flange coupling is a kind of concave and convex tenon alignment of the flange. This kind of flange coupling is easy to process, but it needs to be moved along the axial direction when disassembling. The current dismantling methods such as hammering dismantling method, equipment shaking up and down method, Flange welding as block method, etc. The above devices all exist in use and cannot automatically and quickly open the coupling flange. There are many problems at the same time, the first is high labor intensity, the second is that it is greatly affected by space, the third is unsafe, and the fourth is that it causes damage to the connected equipment, and the effect is not good. ...
