Electric box turnover device

Abstract

The invention relates to an electric box turnover device. Lifting lugs are symmetrically arranged on the top of an outer shell. The device is characterized in that: the shell has a convex framework with an opening; a bracket is arranged between front and back walls; a speed reducer is arranged on the bracket; a turnover motor is connected with the speed reducer and arranged above the speed reducer and in a groove of the shell; the two sides of the speed reducer are symmetrically connected with transmission shafts through couplings; the other end of each transmission shaft is supported on the side wall of the shell through a bearing; each transmission shaft is provided with a plurality of link chain sprockets; the transmission shafts and the link chain sprockets are fixed through keys and keyways; slots and slot grooves are formed on the link chain sprockets at equal intervals; and the widths of the slots and the slot grooves are respectively matched with the width and thickness of the link chain sprockets. The electric box turnover device can realize the controlled motion and stop 360-degree forward and reverse continuous or joggle electric turnover of a sand box, has low rotating speed and high turnover efficiency, stably operates and can be used for the turnover and close of the sand box, the inclined spraying of a flow coating sand box, the turnover of a casting mold and a tool and the turnover of large castings during processing.

Description

technical field [0001] The invention relates to an electric box turning device, which is an electric suspension turning machine used for sand box turning and moving. Background technique [0002] The practical large-scale sand box in the non-mechanized molding section of the foundry workshop often needs to lift the mold to the place where the sand is placed. After the sand is placed, it is necessary to turn over the box. Turn the sand box at a certain angle to spray the paint, and then lift and transport it. Turning over can complete the process of box closing and box opening. These tasks used to be done manually or with the assistance of ordinary crane spreaders. The labor intensity is high, the work efficiency is low, and it is not safe. The sand boxes and molds of some large castings have to be lifted and turned over. Continue to the next process of modeling, and some large castings need to be turned over for painting, cleaning and other processes, but the existing equipm...
