Background

With the rapid development of national economy of China, the demand of ores is increased year by year, and underground ore mining is generalized. In the process of underground ore mining, after a series of processes, ore is conveyed to a storage bin by a mine car and is lowered to each point, and the ore is conveyed to a skip bucket through a belt to be lifted to the ground surface. Each silo is a vital part for mining ore downhole, as damage to the plates inside the silo is increasing over long periods of production.

The necessary body that the feed bin was stored as an ore in the mine production in the pit, reproduction in-process, the inside damage of feed bin can take place for inevitable, if not in time maintenance, the ore will directly strike the bulkhead, will lead to the bulkhead weak upper shed to collapse, but also can fall and cause equipment damage and bodily injury, will lead to whole production line whole to stop production, produces the economic loss of great, brings serious threat for safety in production.

At present, due to the defects and shortcomings of underground stock bin structures, field conditions and the like, a fixed platform cannot be erected for long-term maintenance, so that the maintenance is difficult, the danger coefficient is high, and the maintenance efficiency is low. The main problems are represented as follows:

(1) the high-altitude suspension maintenance difficulty of the operators who do not fix the maintenance platform on the site with the structural problem of the storage bin is avoided;

(2) an operator with the depth of 12 meters in the storage bin adopts a traditional ascending ladder, and when the operator stands on the ascending ladder to carry out maintenance operation, the ascending ladder swings with a large gravity center and unstable standing points, so that the danger coefficient is high;

(3) the operation of climbing ladder left and right does not protect the aerial work of operating personnel and does not depend on and only need one to hold up steady can the maintenance operation, causes one-hand operation, and maintenance efficiency is low.
