Extension shaft guide used for lifting counter level in mine shaft

Abstract

The invention discloses an extension shaft guide used for lifting counter level in a mine shaft, belonging to the field of mine shaft equipment; the extension shaft guide comprises an upper fixed shaft guide and a lower fixed shaft guide which are distributed on a same shaft line; the upper fixed shaft guide is internally sleeved with a movable shaft guide and is internally provided with an oil cylinder; the upper end of the oil cylinder is fixed in the upper shaft guide; a piston rod of the oil cylinder extends out of the lower end of the oil cylinder; the extending end of the piston rod is connected with the upper end of the movable shaft guide; and when the piston rod extends, the movable shaft guide connects the upper fixed shaft guide and the lower fixed shaft guide. When in working, the device can lift the movable shaft guide by the oil cylinder and then can carry out carriage in and out and the mine car can enter and go out smoothly. When the oil cylinder works, the piston rod is pushed to descend so as to lead the movable shaft guide to connect the upper fixed shaft guide and the lower fixed shaft guide; therefore, the lifting of a container can pass smoothly and uninterruptedly along the vertical direction. The extension shaft guide solves the technical problem that the container needs to reduce speed to pass when being lifted, thus greatly improving the operating efficiency.

Description

technical field [0001] The invention relates to a mine shaft equipment, in particular to a tank road. Background technique [0002] In mine vertical shaft hoisting, there is generally one entry and exit level underground, but there are also cases where multiple entry and exit levels are set. Except for the deepest underground level, the rest of the underground levels are intermediate levels. Because the intermediate level has both the in-and-out operation of the lifting container, and the operation that the lifting container needs to pass through the intermediate level at full speed, for the lifting container of the end tank road. When it is necessary to enter and exit the car, it is required that the tank road must be disconnected to allow the mine car to enter and exit smoothly. However, the disconnected tank road cannot allow the lifting container to pass through at full speed, and the "Coal Mine Safety Regulations" stipulates that it must pass through at a reduced speed...

Problems solved by technology

However, the disconnected tank road cannot allow the lifting container to pass through at full speed. The "Coal Mine Safety Regulations" stipulates that it must pass through at a reduced speed, which will greatly affect the lifting efficiency.
