An adjustable multi-rope hoisting device for mines

Abstract

The invention relates to an adjustable and controllable multi-rope lifting device for a mine. The adjustable and controllable multi-rope lifting device comprises a supporting table, a motor and a linkage mechanism; the upper surface of the supporting table is fixedly connected with a first stabilizing table; the motor is located on the right side of a first idler wheel and connected with a rotating shaft on the right side of the first idler wheel through a coupling; and the upper end of the linkage mechanism is engaged with a second bevel gear, the lower end of the linkage mechanism is engagedwith a first bevel gear, and a first locking rope penetrates through the upper end of a first sliding wheel to move downwards, so that the first locking rope drives objects on the lower portion of the mine to be conveyed. Through the linkage mechanism, the motor can simultaneously control starting and stopping of the first idler wheel and a second idler wheel; during object conveying, if the objects are light, an electromagnet in the linkage mechanism can be energized, so that a clamping plate is disengaged with an upper rectangular groove, and in this way, electricity energy can be saved; and when the objects are heavy, the electromagnet is deenergized, an upper driving shaft and a lower driving shaft are connected through the clamping plate, in this way, the conveying environment can besafer, and the conveying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mines, in particular to an adjustable multi-rope lifting device for mines. Background technique [0002] Mine refers to an independent production and operation unit that has a certain level of mining ore mining. A mine mainly includes one or more mining workshops or pits, mines, open pits, etc., and some auxiliary workshops. Most mines also include ore dressing plants. Mine hoisting is Refers to the transportation of ore, coal, waste rock or gangue along the mine shaft, as well as lifting personnel, equipment and equipment, etc. The classification of mine hoisting methods is shown in the table, among which wire rope hoisting is the most widely used. It is lifted and taken out from the mine, which is convenient for the stable operation of mine work. [0003] Existing lifting devices for mines usually use ropes to lift and pull objects in or under mines. In this way, one or two ropes are usually used to as...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of adjustable multi-rope hoisting device for mines, to solve the problem that the existing hoisting devices for mines proposed in the above-mentioned background technology usually use ropes to lift and pull articles in the mine or under the mine, In this way, one or two ropes are usually used to assist the lifting in order to unload the force, but just increasing the number of ropes cannot make the whole lifting process more stable, and cannot effectively increase the working speed of the lifting, so it cannot be accelerated very well. The working efficiency of the lifting, the usual lifting device can't adjust its own height according to the height of the items in the mine, so it can't better complete the problem of maximizing the unloading force
