AI Technical Summary
Technical Problem
The existing construction methods for ore chute mining mechanisms increase the safety risks for construction workers, and are also costly, time-consuming, and difficult to implement.
Method used
An inflatable annular airbag is used to seal the ore-dropping mechanism against the inner wall of the ore pass. Concrete is then lowered through the ash chute to fix the ore-dropping mechanism to the inner wall, eliminating the need for scaffolding and anchor bolt support. The lifting mechanism is controlled from outside the ore pass by a hoisting mechanism.
Benefits of technology
It reduced safety risks for construction workers, shortened the construction period, and reduced project costs and construction difficulty.

Abstract
The application provides a chute ore falling mechanism installation device and a chute ore falling mechanism construction method. The chute ore falling mechanism installation device comprises an ore falling mechanism, a lifting mechanism, a chute pipe, a ring-shaped air bag and an inflation pipe for inflating the ring-shaped air bag. The lifting mechanism drives the ore falling mechanism to ascend and descend in the chute in a way controlled outside the chute. The ring-shaped air bag is installed on the ore falling mechanism and contacts with the inner wall of the chute in an inflated way. One end of the inflation pipe is connected with the ring-shaped air bag and the other end extends to the outside of the chute. A pouring cavity is arranged between the ore falling mechanism and the inner wall. The chute pipe extends into the pouring cavity from the outside of the chute. The ore falling mechanism is installed by pouring the concrete transported by the chute pipe and the inner wall. The application avoids the risk of personnel working in the chute, reduces the security risk, shortens the construction period and reduces the construction difficulty.
