Problems solved by technology

This method of changing rolls is time-consuming and labor-intensive. Because the number of vehicles in the workshop is limited and the time occupied is irregular, it is often necessary to wait for driving when the equipment is changing rolls, and sometimes it is even necessary to wait for several hours before starting to change rolls, which directly affects the efficiency of roll changing And the production rhythm, and the operation of the crane requires workers to cooperate up and down, and its lifting and other operating precision is low, which increases the labor intensity of workers and the danger of operation

Abstract

The invention relates to a lifting swing arm roller replacing device. The lifting swing arm roller replacing device comprises a roller replacing rack, two swing arms, a lifting driving mechanism and aswing driving mechanism, wherein bearing parts suitable for supporting a roller shaft are arranged on the swing arms, the two swing arms can swing in a horizontal plane and are each provided with a swing arm working position where the swing arm swings to the outside of the roller replacing rack and a swing arm standby position where the swing arm is arranged in the roller replacing rack. The twoswing arms and the swing driving mechanism are driven by the lifting driving mechanism to ascend and descend together, or the two swing arms and the lifting driving mechanism are driven by the swing driving mechanism to swing together. According to the lifting swing arm roller replacing device, the lifting swing arm roller replacing device is arranged beside the equipment with the roller replacingrequirement, by means of the supporting and protecting effect of the swing arms, roller replacing operation can be conveniently and rapidly completed in an assisted mode, the roller replacing operation difficulty of maintenance personnel is effectively lowered, the workload of the maintenance personnel is lightened, and the operation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a lifting swing arm roll changing device and a roller coating unit equipped with the lifting swing arm roll changing device. Background technique [0002] In the production line in the metallurgical field, the rolls of the equipment often need to be replaced, and the help of the driving is often needed when changing the rolls. If the driving is required to hang the old roll to be replaced, after the workers remove the bearing housing and other parts, the driving will lift the old roll away. Or when the roller is installed, the new roller / grinding roller is hoisted by driving, lowered to the installation height of the roller, and the ropes of the hanging roller are disengaged after the workers have installed the parts such as the bearing seat. This method of changing rolls is time-consuming and labor-intensive. Because the number of vehicles in the work...
