Abstract

The invention provides a continuous deslagging device and method for a vertical shaft. The continuous deslagging device for the vertical shaft comprises a conveying system (8), a chain storage device (3) and a locking device (2), the chain storage device (3) comprises a first redirection fixed shaft group (301), a second redirection fixed shaft group (302) and a redirection movable shaft group (303), the conveying system (8) comprises a first conveying chain section (804) and a second conveying chain section (805), and the locking device (2) can lock and fix the first conveying chain section (804) and the second conveying chain section (805). According to the continuous deslagging device and method for the vertical shaft, continuous downward tunneling can be carried out along with a main machine, synchronous operation of deslagging and the main machine is guaranteed, and the conveying chain has an automatic telescopic function and has the chain storage capacity. Meanwhile, the whole conveying system is provided with a self-adaptive tensioning system, and the tensioning force of the conveying system in the operation process is guaranteed.

Description

technical field [0001] The invention relates to the field of tunnel excavation equipment, in particular to a continuous slagging device for shafts, and a continuous slagging method for shafts. Background technique [0002] During the current shaft construction process, slag discharge is a key factor affecting construction efficiency. Existing dry slagging technologies include bucket slagging, vacuum slagging, grab bucket slagging, etc. For bucket and grab slag discharge, although the operation is simple, the slag discharge is not continuous and the efficiency is low. For vacuum slag extraction, the problem of slag particles blocking the pipe occurs frequently, resulting in high energy consumption and low efficiency. How to continuously and efficiently complete shaft slag extraction is an important and difficult problem that needs to be solved urgently. Contents of the invention [0003] In order to realize the continuous slagging during the downward excavation of the sh...
