Detection and maintenance device and method for long nozzle holder of continuous casting machine

Abstract

The invention discloses a detection and maintenance device for a long nozzle holder of a continuous casting machine, which comprises a bracket, an upper pressing mechanism and a force measuring unit, and is characterized in that the bracket comprises a bottom plate, an annular supporting plate and a plurality of supporting columns arranged on the bottom plate, and the annular supporting plate is arranged above the bottom plate through the supporting columns; the upper surface of the annular supporting plate is provided with a plurality of hitching legs matched with the rotary buckles on the upper half portion of the clamping device. The upper pressing mechanism is arranged on the bottom plate and is used for upwards pressing the lower half part of the clamping device; and the force measuring system is used for detecting the pressure between the upper pressing mechanism and the lower half part of the pressing clamp holder in real time. The invention further discloses a detection and maintenance method. According to the invention, maintenance personnel can rapidly detect and maintain the clamp holder without dismounting the spring, and the maintenance efficiency of the clamp holder is improved.

Description

technical field [0001] The invention relates to a long nozzle of a continuous casting machine, in particular to a detection and maintenance device and a method for a long nozzle holder of a continuous casting machine. Background technique [0002] It has become a trend in continuous casting operations that the continuous casting machine disassembles and assembles the long shroud from the ladle to replace the manual labor. The robot realizes the function of disassembling and assembling the shroud through the gripper. The structure of the long nozzle holder is as follows Figures 1 to 2 As shown, it mainly includes upper and lower parts. The upper part 1 is in the shape of a twist button, which can be hung on the sliding nozzle mechanism of the ladle by rotating; the lower part 2 is used for placing the long nozzle and nozzle positioning; the upper and lower parts pass through Four preloaded springs 3 are connected. When the robot screw the gripper onto the ladle, as the scr...

Problems solved by technology

[0004] At present, there is only one offline spring testing tool for the inspection and maintenance of the shroud holder. Only after the spring is removed from the holder can the tool be used to test the elastic properties of each spring one by one. The entire inspection process Cumbersome and limited detection range

For the lubrication and maintenance of the holder spring, since the upper and lower parts of the holder are clamped by the spring in the normal assembly state, it is necessary to lubricate the spring rod between the upper and lower parts, and the spring must also be removed from the holder. It can only be realized after the holder is removed, resulting in the inability to realize the timely maintenance of the holder during the production turnover
