Connecting device of steel ladle turret connecting rod and fixed support pin shaft and installation method

Abstract

The invention provides a connecting device of a steel ladle turret connecting rod and a fixed support pin shaft and an installation method. The connecting device comprises a tray, a pin shaft, a supporting frame and a fixing support. The tray is erected on a steel ladle turret and is used for bearing and connecting a connecting rod on the steel ladle turret; the pin shaft is used for connecting the connecting rod borne by the tray and aligning the centers of the tray and the connecting rod; the supporting frame is connected with the steel ladle turret and used for bearing and fixing the tray; and the fixing support is connected with the supporting frame and is used for fixing the pin shaft. The connecting device of the steel ladle turret connecting rod and the fixed support pin shaft and the installation method has the beneficial effects that the arranged V-shaped tray can hoist the pin shaft needing to be mounted to a mounting plane in advance, and the specific elevation and the left-right position of the pin shaft are adjusted by increasing or decreasing gaskets on the lower portion of the V-shaped tray; and the stress of the assembled pin shaft is uniform, so that the situation that parts are damaged due to the fact that the pin shaft is hit by a sledge hammer is avoided, the construction time of equipment assembly is shortened, and the installation efficiency of the equipment assembly is improved.

Description

technical field [0001] The invention belongs to the field of equipment connection and installation, and in particular relates to a connection device and an installation method for a connecting rod of a ladle turret and a pin shaft of a fixed support. Background technique [0002] When the assembly is installed in continuous casting or ESP equipment, in the process of threading the connecting rod and the fixed support of the ladle turret, it is necessary to thread the connecting rod and the shaft support together first, and then install the bearing end covers on both sides. Due to the limitation of the hoisting space during the hoisting process, only one crane in the workshop can be used to hoist the connecting rod during assembly, and the pin shaft cannot be hoisted by the crane due to the limited space when threading the shaft. In the past, the cantilever steel was welded on the support , Use chain hoists to lift the shaft for assembly, which will affect the equipment compo...

Problems solved by technology

Due to the limitation of the hoisting space during the hoisting process, only one crane in the workshop can be used to hoist the connecting rod during assembly, and the pin shaft cannot be hoisted by the crane due to the limited space when threading the shaft. In the past, the cantilever steel was welded on the support , the chain hoist is used to lift the shaft for assembly, which will cause the equipment components to be affected by the force of the equipment welding, and the surface of the shaft is smooth during hoisting, and it is not easy to bind. It is very dangerous during the assembly process, and it is difficult to find the shaft hole.
