Demounting, mounting and maintenance tool for flotation machine

Abstract

The invention discloses a demounting, mounting and maintenance tool for a flotation machine. The demounting, mounting and maintenance tool for the flotation machine comprises a machine base platform (A), a movable support bracket (B), a fixed support bracket (C), a movable rail trolley (D), a hydraulic lifting system (E) and a maintenance support plate system (F), wherein the movable support bracket (B) and the fixed support bracket (C) are oppositely installed at the right end of the machine base platform (A); the movable rail trolley (D) is installed at the left end of the machine base platform (A); the hydraulic lifting system (E) is mounted on the movable rail trolley (D); the maintenance support plate system (F) is installed above the hydraulic lifting system (E); the machine base platform (A), the movable support bracket (B), the fixed support bracket (C), the movable rail trolley (D), the hydraulic lifting system (E) and the maintenance support plate system (F) integrally form the demounting, mounting and maintenance tool. According to the demounting, mounting and maintenance tool, the flotation machine is more convenient to maintain, time and labor are saved, the replaced new assemblies of the flotation machine are prevented from causing scratches and damage in the process of mounting, assembly accuracy is improved, existent potential safety hazards when the flotation machine is disassembled and assembled are eliminated, and a premised guarantee is provided for stabilizing indicators in beneficiation.

Description

technical field [0001] The invention relates to a maintenance tool, in particular to a disassembly and maintenance tool for a flotation machine. Background technique [0002] Flotation machine is a mineral processing equipment widely used at home and abroad. The flotation system in the beneficiation process needs to work continuously for 24 hours. The flotation machine needs to be immersed in the flotation tank. Under the continuous impact and wear of the pulp flow and the corrosion of the chemical agent, the flotation machine is prone to failure. The maintenance of the flotation machine The main contents are: the replacement of impeller and cover plate (also called rotor and stator), the adjustment and replacement of bearings, the replacement of main shaft protection sleeve, and the number of flotation machines used in large and medium-sized flotation plants is large, and it cannot be used in flotation For direct repair on the selected tank, it is necessary to lif...

AI Technical Summary

Problems solved by technology

[0003] In actual production, maintenance workers use bridge cranes to hoist the flotation machine as a whole and move it to the maintenance site. The bearing body of the flotation machine is framed by rails or channel steel, while the center tube needs to be suspended by a crane all the time. When replacing the impeller and cover plate, multiple workers need to hold the loose impeller and cover plate with their hands at the same time. Due to the heavy weight of the disassembled parts, it is easy to cause accidental injury and pose a safety hazard. When replacing new components, in order to ensure that the impeller and cover plate The gap between the shafts is kept within the specified range, and at the same time, the concentricity of the impeller and the cover plate must be ensured to ensure that the radial gap is equal to the surroundings. It is necessary for the maintenance workers and the crane workers to closely cooperate with the lifting and lowering of the crane to center , not only time-consuming and labor-intensive, but also the effect is poor. Often the installation gap is not in place, and the workers are forced to use a sledgehammer to repeatedly hit the impeller to force it forward, resulting in scratches on the smooth part of the impeller and the spindle tip. When installing the bearing, it is easy to cause damage to the inner side of the bearing. Gnawing wear occurs between the main shaft and the smoothness between the components is reduced or even damaged. Insufficient assembly accuracy at any point will directly reduce the service life of the flotation machine, reduce the operating rate, and cause poor flotation indicators. influences
