Lifting appliance for disassembling and assembling vertical grinding roller sleeve

Abstract

The invention relates to the technical field of lifting appliance equipment, and discloses a lifting appliance for disassembling and assembling a vertical grinding roller sleeve. The lifting appliance comprises a grinding roller sleeve body, a check ring is arranged on the outer surface of the outer side of the grinding roller sleeve body, and multiple sets of mounting bases are arranged on the outer surface of the outer side of the check ring. Lifting hooks are arranged on the inner sides of the mounting bases and located on the outer surface of the bottom of the grinding roller sleeve body, first connecting rods are arranged at the tops of the lifting hooks and located on the inner sides of the mounting bases, and lifting bases are arranged on the outer surfaces of the tops of the corresponding first connecting rods. Second connecting rods are arranged in the lifting bases and located on the inner sides of the connecting rods on the two sides, positioning blocks are arranged at the bottoms of the corresponding second connecting rods and located in the check ring, and pressing bases are arranged at the bottoms of the positioning blocks and located on the outer surface of the top of the grinding roller sleeve. According to the lifting appliance for disassembling and assembling the vertical grinding roller sleeve, the grinding roller sleeve is fixed in a disassembling and assembling mode, the grinding roller sleeve can be automatically pressed during hoisting, and the stability during transportation is improved.

Description

technical field [0001] The invention relates to the technical field of sling equipment, in particular to a sling for dismounting and assembling roller sleeves of vertical mills. Background technique [0002] As an energy-saving, mature and stable grinding and drying equipment, vertical mills are widely used in the cement industry, such as raw material vertical mills, coal powder vertical mills, mineral powder vertical mills, etc. The roller sleeve of the vertical mill is not only an important part of the vertical mill, but also a wearing part of the vertical mill equipment. Because the working mechanism of the vertical mill is to grind the material between the roller sleeve and the grinding disc, the roller sleeve of the vertical mill wears quickly and needs to be replaced frequently. Since the shutdown of the vertical mill has a great impact on production, the reliability of the vertical mill is very important. If the time for changing the roller sleeve of the vertical mi...
