Problems solved by technology

[0003] At present, there are problems in the maintenance of the flotation machine: the maintenance workers use the bridge crane to move the flotation machine that has been hoisted out to the maintenance site, and the upper part of the flotation machine bearing body is simply erected with a dowel or channel steel, while the central cylinder The lower part needs to be suspended by a crane all the time. When disassembling the impeller and cover plate, several 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 to the workers, so there are many problems. big security risk
When replacing new components, in order to ensure that the axial clearance and radial clearance between the impeller and the cover plate are qualified at the same time, it is necessary for the maintenance workers to cooperate closely with the crane workers and repeatedly lift and lower the crane to center. This method is not only time-consuming and labor-intensive but also effective. Poor, often the installation gap is not in place, 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 gnawing wear between the inner side of the bearing and the main shaft, reduce the smoothness between components, and even cause component damage
In the maintenance process, no matter where the precision of the maintenance assembly is not enough, it will directly reduce the service life of the flotation machine, reduce the operation rate, and also cause adverse effects on the flotation index

Abstract

The invention relates to the field of maintenance technologies for mine machine assemblies, in particular to a tool special for overhauling a flotation machine and an overhauling method. The tool special for overhauling the flotation machine is characterized by comprising a machine base platform, a fixed supporting bracket, a movable supporting bracket, a movable track car, a hydraulic lifting system, an overhauling support plate device and a safety fence device, wherein the fixed supporting bracket, the movable supporting bracket, the movable track car, the hydraulic lifting system, the overhauling support plate device and the safety fence device are arranged on the machine base platform, and the fixed supporting bracket and the movable supporting bracket are composed of side face stand columns, bracket stand bars, transverse connecting plates, adjusting gaskets, full thread long rods and trapezoid supports with concave grooves. The tool special for overhauling the flotation machine is easy to operate and convenient for overhauling workers to use, can improve labor productivity of an enterprise substantially because the tool is high in overhauling accuracy, ensures overhauling quality, improves overhauling efficiency and can reduce labor intensity of the workers substantially, and is suitable for being popularized and used for overhauling engineer of various mine floatation machines.

Description

technical field [0001] The invention relates to the technical field of maintenance of mining machine components, in particular to a special appliance for maintenance of a flotation machine and a maintenance method. Background technique [0002] Flotation machine is a mineral processing equipment widely used in mines at home and abroad. The equipment is mainly composed of main components such as belt pulley, bearing body, central cylinder, main shaft, impeller, cover plate and suction pipe. Since the flotation system in the beneficiation process needs to work continuously for 24 hours, the flotation machine is immersed in the flotation tank, and it is prone to failure under the continuous impact and wear of the pulp flow and the corrosion of the chemical agent, so it needs regular or irregular maintenance. The main content of flotation machine maintenance is: replace the impeller and cover plate (also called rotor and stator), replace or adjust the bearing, replace the main ...
