Description

Mine lifting machine

Technical Field

The utility model relates to the technical field of mining machinery, in particular to a mine hoisting machine.

Background

There are two kinds of existing mine elevators, one is a winding elevator and the other is a multi-rope friction elevator. The two kinds of hoists have the common characteristic that the hoisting terminal load acts on the winding drum of the hoist, the winding drum bears large tension and the power consumption is high.

Lifting the terminal load includes lifting the container dead weight and the load, wherein the lifting the container dead weight is approximately half of the terminal load, and each lifting is approximately half of the dead load. The problems that mining depth is increased year by year and lifting capacity is required to be increased are all faced to mines, and the problems that lifting equipment is added or larger lifting equipment is replaced in new projects of mines are solved. Therefore, how to improve the lifting efficiency of the elevator is an urgent problem to be solved.

Detailed Description

The utility model is further described below with reference to the accompanying drawings. It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

In the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

The mine hoist comprises a driving reel wheel, a driven wheel, a lifting container, a balance dead weight container and a balance load container, wherein the driving reel wheel consists of a first driving reel wheel 1 and a second driving reel wheel 2, and the driven wheel consists of a first driven wheel 3 and a second driven wheel 4;

as shown in fig. 2 and 3, the first driving reel wheel 1 and the second driving reel wheel 2 are combined and fixed together, one end of the first main wire rope 8 is fixed on the lifting container 5, the other end of the first main wire rope 8 bypasses the first load-carrying head sheave 12 and then is fixed on the first driving reel wheel 1, one end of the second main wire rope 9 penetrates through a through hole in the center of the balance weight container 7 and then is fixed on the balance weight container 6, and the other end of the second main wire rope 9 bypasses the second load-carrying head sheave 13 and then is fixed on the second driving reel wheel 2;

as shown in fig. 2 and 4, one end of the first slave wire rope 10 and one end of the second slave wire rope 11 are respectively fixed on the lifting container 5, the other end of the first slave wire rope 10 bypasses the first balance head sheave 14, the first driven wheel 3 and the third balance head sheave 16 and then is fixed on the balance weight container 7, and the other end of the second slave wire rope 11 bypasses the second balance head sheave 15, the second driven wheel 4 and the fourth balance head sheave 17 and then is fixed on the balance weight container 7.

The first driving winding drum wheel 1 and the second driving winding drum wheel 2 are steel wire rope winding wheels or multi-rope friction wheels.

The first driven wheel 3 and the second driven wheel 4 are both provided with emergency braking devices.

The first driven wheel 3 and the second driven wheel 4 are arranged in a lifting machine room or at the top of a derrick or a well tower.

The balancing load container 6 is a cage or a skip.

A certain distance is arranged between the balance weight container 6 and the balance dead weight container 7 so as to ensure that the balance weight container 6 and the balance dead weight container 7 are not contacted.

According to the utility model, the first driving reel wheel 1 and the second driving reel wheel 2 bear the lifting of the effective load in the lifting container 5, and the first driven wheel 3 and the second driven wheel 4 bear the lifting of the dead weight of the lifting container 5. The driving reel wheel is powered, the driven wheel is unpowered, and the driven wheel has an emergency braking function.

The load-carrying head sheave and the balance head sheave are both fixed on the head sheave beam, which is the prior art.

As shown in fig. 3 and 4, when the driving reel wheels 1 and 2 are driven by power to rotate, the driven wheels 3 and 4 are driven by the lifting container 5 to rotate, and a certain gap is reserved between the balance load container 6 and the balance dead weight container 7, so that contact and collision are avoided.

When the steel wire rope 8 breaks, the lifting container 5 is required to fall, at this time, as the lifting container 5 is further connected with the two steel wire ropes 10 and 11, the steel wire ropes 10 and 11 are connected with the other end balance dead weight container 7 through the driven wheels 3 and 4 and the steel wire ropes 13 and 12, and the driven wheels 3 and 4 are braked emergently, so that the steel wire ropes 10 and 11 do not slide, the lifting container 5 is in a static state, the falling does not occur, and the personnel safety is ensured.

According to the concrete condition of the mine, whether a tail rope is added below the lifting container 5 is determined.

When the minerals are lifted, as shown in fig. 5, the lifting container 5 is filled with the minerals under the bottom of the well, the driving reel 1 rotates under the power drive, the lifting container 5 ascends from the well shaft, and the balance load container 6 descends. The lifting container 5 and the balance load container 6 are connected to the driving reel wheel and are driven up and down by power. The lifting container 5 naturally descends while the other end connected by the wire ropes 10, 11 balances the dead weight container 7.

When the driving reel 1 rotates reversely under the power drive, the balance load container 6 rises, the lifting container 5 descends under the action of the load carried by the driving reel, and the balance dead weight container 7 synchronously rises under the action of the lifting container 5. The lifting container 5 is loaded by a person who goes into a well, an empty mine car and the like, the minimum weight of the lifting container is larger than that of the balance weight container 7, and the gravity difference of the lifting container is required to generate certain acceleration so as to enable the balance weight container 6 and the balance weight container 7 to synchronously operate.

According to the concrete condition of the mine, a rope adjusting device is arranged at the joint of the steel wire ropes 10 and 11 at the top of the lifting container 5.

For the sake of comparative clarity, the comparison is made according to three designs with the existing shaft equipment conditions of the mine unchanged:

the first scheme is as follows: the existing hoisting system of the mine;

the second scheme is as follows: to increase the throughput, the lifting vessel is changed from a single-layer tank to a double-layer tank while still using a common lifting system;

third scheme: after changing into a double-layer tank, the lifting system is changed.

The third scheme is the best from the table, because the safety coefficient is the largest, and two steel ropes with the diameter of 12.5mm can be used as safety insurance, and the safety is the most reliable.

From the above table it can be seen that the third solution and the first solution increase the lifting capacity by 60%.

As can be seen from the above table, the power consumption is lowest with the third embodiment.
