A device for overhauling the inner wall of a ball mill barrel

Abstract

The invention provides an inspection device for the inner walls of ball mill barrels. The inspection device comprises an integrated frame, suspended walking units, a liner plate repair arm, a lighting and image pick-up system and a remote console, wherein a hydraulic driver and an integrated power distribution system are arranged inside the integrated frame; suspended walking units are arranged on the two ends of the integrated frame; the liner plate repair arm comprises a top clamp rocker arm and a welding and cutting rocker arm and is mounted in the middle of the integrated frame; each of the top clamp rocker arm and the welding and cutting rocker arm is provided with a shaft sleeve type rocker arm seat, a telescopic rocker arm rod and a stretching rocker arm rod; the remote console is connected with the integrated power distribution system by use of a centralized control cable. The suspended walking units of the inspection device for the inner walls of the ball mill barrels is connected with one ball mill barrel by virtue of electromagnetic attraction and is capable of moving transversely and conveniently; a damaged protective liner plate is repaired by use of the liner plate repair arm; an inspection worker can repair the damaged protective liner plate by use of the remote console outside the ball mill barrel without being injured; as a result, the inspection device for the inner walls of the ball mill barrels is reasonable in structure, simple to operate and control, and capable of working instead of the inspection workers.

Description

technical field [0001] The invention belongs to an overhaul tool, in particular to an overhaul tool which enters into the inner cavity of a ball mill barrel for overhaul work. Background technique [0002] In coal-fired power plants, cement manufacturing plants and various mineral processing plants, ball mills are often used to crush various materials such as coal, stone and ore into powder. During the operation of the ball mill, production is often stopped due to the impact and damage of the protective liner on the inner wall of the cylinder by steel balls and materials. In order to resume production in time, maintenance workers must brave the danger of high temperature, dust and toxic and harmful gases to damage their bodies. The inner chamber of the ball mill barrel repairs the damaged protective liner, so maintenance workers are often injured when working in the ball mill barrel. Contents of the invention [0003] In order to solve the problem in the prior art that ma...
