A method and device for relay lifting and transportation of multiple winches in the same inclined shaft

Abstract

Disclosed are a method for relaying lifting transportation of multiple winches in the same inclined shaft and a device of the method. Two or more winches conduct relaying lifting transportationin the same inclined shaft. A rail within the range of a middle-segment flatcar field where a middle-segment winch house is located is arranged to a movable reverse suspension bridge. An upper mine car can be delivered from the upper portion of the inclined shaft to the lower portion of the inclined shaft or a car field on the lower portion of the inclined shaft through a suspension bridge by closing the reverse suspension bridge. The newly added middle-segment winch house can normally operate by lifting the suspension bridge, thus the requirement of lifting transportation work of the lower portion of the inclined shaft is met, and the requirement of relaying lifting transportation of the upper portion and the lower portion of the same inclined shaft is met. According to the method and device, the requirement of down-shaft relaying lifting transportation is met, initial investment is reduced, meanwhile, the requirements of non-downward extending in early design and inclined shaft lifting needing continued downward extending in the later period are also met, the needed cost is relatively low, the construction time is short, and the effect is achieved fast.

Description

technical field [0001] The invention relates to a method and a device for relay lifting transportation of multiple winches in the same inclined shaft. Background technique [0002] In the development and transportation of inclined shafts, due to the downward extension of ore veins, inclined shafts also need to be continuously extended downwards. Since inclined shafts are completed in stages, and the time for this staged segment is relatively long, ranging from a few years to more Therefore, at the beginning of the design of the inclined shaft, in order to save investment and reduce energy consumption, the hoist load design standard of the inclined shaft will be set at a lower level, which generally meets the initial design load. The extension of the inclined shaft, the deepening of the inclined shaft, and the lifting distance of the inclined shaft has exceeded the initial setting of the hoist, the extension of the inclined shaft needs to be realized in the following two ways...

[0002] In the development and transportation of inclined shafts, due to the downward extension of ore veins, inclined shafts also need to be continuously extended downwards. Since inclined shafts are completed in stages, and the time for this staged segment is relatively long, ranging from a few years to more Therefore, at the beginning of the design of the inclined shaft, in order to save investment and reduce energy consumption, the hoist load design standard of the inclined shaft will be set at a lower level, which generally meets the initial design load. The extension of the inclined shaft, the deepening of the inclined shaft, and the lifting distance of the inclined shaft has exceeded the initial setting of the hoist, the extension of the inclined shaft needs to be realized in the following two ways: 1. Re-set one or more inclined shafts downward, so that different vertical The level road in the middle of the depth is connected by multiple inclined shafts to form a relay lift; 2. Extend the original inclined shaft, replace the hoist of the original inclined shaft, and configure a new hoist according to the required load; but adopt the first method , it is necessary to re-select the location to excavate the inclined shaft, and it is necessary to carry out geological survey and safety audit on the excavation point, which is time-consuming and expensive. The second method requires the redesign and transformation of the winch machine room, which requires high investment costs and takes a long time.
