Steel wire rope dragging type telescopic cage guide

Abstract

A steel wire rope dragging type telescopic tank road, including a channel steel upper guide rail and a channel steel lower guide rail, a movable guide rail is arranged under the channel steel upper guide rail, a pulley is installed on the inner upper part of the channel steel upper guide rail, and the inner lower part of the channel steel upper guide rail There is a baffle with arc-shaped grooves, and a limit baffle that is slidably matched with the baffle with arc-shaped grooves is welded symmetrically on the inner side of the upper end of the movable guide rail; a lifting wire rope is wound on the pulley, and one end of the lifting wire rope is connected to the hoistway. The side winch is connected, and the other end is connected with the main shaft extending into the movable guide rail. The main shaft is provided with two positioning devices at intervals and a stretching device arranged on both sides of the two positioning devices. The invention overcomes the limitation of the opening length of the intermediate horizontal tank channel, and can realize the expansion and contraction of the tank channel with a large stroke or even a super large stroke.

Description

technical field [0001] The invention relates to the field of mine hoisting equipment, in particular to a wire rope dragging telescopic tank road suitable for cage lifting. Background technique [0002] At present, cage lifting transportation is the main way of shaft personnel transportation. Shafts generally have multiple horizontal layers. When the cage reaches the horizontal layer, mine car personnel can enter and exit the cage, and take the cage to reach different horizontal layers. When mining vehicles and personnel need to enter and exit the cage, the cage tank must be disconnected to allow the mining vehicles and personnel to pass through smoothly. At this time, there are fractures in the tanks of each horizontal layer. When the cage runs through the horizontal layer due to the lack of tank guides , can not run at full speed, otherwise it is easy to cause accidents; due to the existence of tank road fractures, the cage must slow down when passing through each horizon...

AI Technical Summary

Problems solved by technology

The patent No. CN10151314A discloses a telescopic tank for raising the middle level of mine shafts, although it can solve the problem of tank fractures, but its expansion and contraction is driven by a hydraulic cylinder. The telescopic length of the cylinder is limited and it is difficult to popularize it. Therefore, it is necessary to propose a new type of telescopic tank to overcome the bottleneck of the telescopic length of the hydraulic cylinder.
