Electric millstone tile lifting appliance

Abstract

The invention discloses an electric millstone tile lifting appliance which is composed of a rigging turnbuckle, a lifting beam, a lifting appliance body, a connecting bolt, an electric hoist, a sleeve and a millstone tile, the millstone tile and the electric hoist are connected and fixed through the lifting appliance body, the other end of the electric hoist is fixed to the lifting beam, one end of the lifting beam is fixed to a medium-speed coal mill access door frame. The other end of the lifting beam is fixed on a middle frame body lifting lug, and electric hoisting of the millstone tile in a narrow space of the coal mill is achieved. The lifting tool body is composed of an upper cantilever, a lower cantilever and a connecting beam, a special structure is designed at one end of the lifting beam to be connected with a door frame of an access door of the coal mill, and the other end of the lifting beam is fixed to a sleeve welded on site on the lifting lug of the middle frame body of the coal mill. In order to adjust the balancing requirement, the hoisting beam and the sleeve are connected and fixed through the rigging turnbuckles, so that electric hoisting of the millstone tile in the coal mill is achieved. The labor input is reduced when the millstone tile is mounted and dismounted, the overhauling efficiency of the millstone tile is improved, and the overhauling cost of the medium-speed coal mill is reduced.

Description

technical field [0001] The invention belongs to the technical field of medium-speed coal mills for pulverizing and crushing equipment, and in particular relates to medium-speed coal mill equipment for coal-fired thermal power plants, chemical plants or iron and steel smelting plants. Background technique [0002] The mill plate is the main vulnerable part of the medium-speed coal mill, which affects various operating parameters of the medium-speed coal mill. The overhaul of the grinding tile is the focus of the overhaul work of the medium-speed coal mill, which directly determines the overhaul efficiency and cost of the medium-speed coal mill. The inner space of the medium-speed coal pulverizer is narrow, and the shape of the disc tiles is irregular, which makes the maintenance and lifting of the disc tiles very cumbersome. Therefore, the maintenance and lifting work of the millstone must be simple and efficient, in order to improve the maintenance efficiency of the medium-...
