A vertical shaft continuous excavation hoisting system and its hoisting method

Abstract

The invention provides a vertical shaft continuous tunneling elevation system and an elevation method thereof. The system comprises a vertical elevating device which comprises a machine tail platformfeeding section, a vertical elevating section and a horizontal discharging section. A head transmission drum is arranged on the end portion of the horizontal discharging section. A tension adjusting device capable of adjusting the length, entering a vertical shaft, of a stop conveying belt on the vertical elevating device is arranged in the horizontal discharging section. The head transmission drum can carry out reciprocating linear motion in the telescoping direction of the stop conveying belt under the effect of the tension adjusting device, and a lifting adjusting device used for adjustingthe installing height of the machine tail platform feeding section is arranged on the bottom of the machine tail platform feeding section. The invention further provides the method for carrying out continuous tunneling and elevating on the continuous tunneling elevating system. According to the system and the method, continuous loading and transporting can be achieved, the working efficiency of excavation of the vertical shaft is improved, the number of times for vertically elevating the stop conveying belt connectors is reduced, the safe coefficient of the material elevating system is improved, and synchronous linkage of the stop conveying belt elevating system and an under-shaft tunneling system is achieved.

Description

technical field [0001] The invention relates to the technical field of conveying machinery, in particular to a shaft continuous excavation lifting system and a lifting method thereof. Background technique [0002] In recent years, international mining has developed from shallow open-pit mines to deep mines. The mining depth has increased. At the same time, the effective operating area has shrunk, the mining project in the ore area has dropped sharply, the working platform has narrowed, and the ore and rock transportation distance has increased. The lifting capacity gradually cannot meet the needs of its development, and the lifting capacity of the main well has become the bottleneck of the entire underground transportation capacity. At the same time, with the continuous development of my country's water conservancy industry, construction projects continue to increase, and more and more tunnels or tunnel construction projects have solved the vertical lifting capacity of the m...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a shaft continuous excavation lifting system and its lifting method, which solves the problem in the prior art that the excavation and hoisting transportation of the belt conveyor cannot form a continuous effect and affects the progress of the excavation, and the sidewall is increased with the increase of the excavation depth. The conveyor belt needs to be extended many times, resulting in many joints, low safety factor and long downtime, which affect economic benefits
