Description

Swing type isolating device for coal mine paste filling mining

Technical Field

The utility model relates to a colliery lotion filling and exploiting equipment field specifically discloses a colliery lotion filling and exploiting's oscillating isolating device.

Background

The coal mine goaf refers to a cavity or cavity left underground after coal and other ores are conveyed away in the coal mining process, if the cavity or cavity is not filled, the ground subsides and falls, so that villages, pipelines, bridges and railways are damaged; the farmland sinks to cause large-area water accumulation and land salinization, so that the farmland cannot be cultivated, and in addition, the formation of a coal mine goaf can cause the problems of environmental pollution, low underground resource recovery efficiency, frequent underground accidents of coal mines and the like. In recent years, coal mine paste filling technology is gradually used to solve the above problems. The coal mine paste filling technology is that coal gangue, fly ash, cementing material, water, municipal solid waste, river sand and other materials are made into paste slurry and enter an underground goaf through a filling pipeline under the action of pump pressure or gravity. Through years of research and development, the coal mine paste filling technology tends to mature, and the key problems to be solved at present are to improve the filling efficiency and reduce the filling cost.

At present, the problem of isolation and leakage stoppage of a region to be filled with paste for coal mining is one of the main difficulties in improving the filling mining efficiency. If the isolation and leakage stoppage work is carried out only by adopting a manual mode, the operation is complex, the labor intensity of workers is high, the consumed time is long, the efficiency is low, the isolation and assembly of the traditional support is complex, an isolation retaining wall needs to be built by adopting a manual mode, the mechanization degree is low, the isolation angle cannot be changed according to the on-site condition, and the paste filling coal mining efficiency is seriously restricted.

Therefore, the inventor provides a swing type isolating device for coal mine paste filling mining, which takes rich design development and practical manufacturing experience in related industries for years, researches and improves the existing structure and defects so as to solve the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve traditional colliery lotion filling mining isolating device and can not change the problem of keeping apart the angle according to the in-service use condition.

In order to achieve the purpose, the basic scheme of the utility model provides a swing type isolating device for coal mine paste filling mining, which comprises a base, wherein the surface of the base is fixedly connected with a concave cylinder seat, a support plate is rotationally connected on the cylinder seat, a first cylinder is fixedly connected on the support plate, and a partition plate is rotationally connected on one side of the base, which is far away from the cylinder seat;

the concave connecting seat of baffle one side fixedly connected with is equipped with the bracing piece on the connecting seat, fixedly connected with go-between on the bracing piece, the working end fixed connection of go-between and first cylinder, sliding connection has the expansion board in the baffle both sides, one side expansion board is equipped with the card strip at the edge of keeping away from the baffle, the opposite side expansion board sets up and blocks strip assorted draw-in groove at the edge of keeping away from the baffle, the baffle one side still symmetry is equipped with the second cylinder, the equal fixed connection of working end of second cylinder is on the expansion board.

The principle and effect of this basic scheme lie in:

1. the first cylinder fixed connection who sets up can change the angle through the extension board on the go-between, and first cylinder, and the swivel becket can pass through bracing piece free rotation, like this alright with when first cylinder carries out work, first cylinder can change the relative angle of extension board along with the flexible of first cylinder pole, thereby the go-between also can rotate the angle of adaptation and drive the relative base of baffle and change working angle.

2. The expansion plates arranged on the two sides of the partition in a sliding mode are recovered when the isolating device is not used, so that a relatively narrow and small crowded mine can be greatly saved, the expansion plates can be actively pushed out through the second air cylinders arranged on the partition in the working process, the working strength of coal miners is reduced, and the isolating range is also enlarged.

3. The expansion board of one side is equipped with the card strip, and the opposite side expansion board is equipped with the draw-in groove that can agree with each other with the card strip to in every isolating device appear not hard up or the gap influences isolation effect when the cooperation is used, go on in proper order like this the card strip of preceding isolating device and the cooperation of the card strip of next isolating device together in the use, alright carry out lotion packing isolation work to whole mine.

Compared with the prior art, because the colliery is changeable at mining in-process operational environment, traditional isolating device can not keep apart the change of angle according to traditional operational environment, and what be stiff keeps apart, very big influence like this keeps apart the effect, and the utility model discloses alright with keep apart the angle according to operational environment, the expansion board that increases moreover can enlarge the isolation scope when using, has solved the problem that the crowded storage space of mine is little when idle.

Further, the cylinder block is connected with the extension board in a rotating manner and the connecting seat is connected with the support rod in a rotating manner, and the dustproof bearing is used at the joint. Because can produce a large amount of dusts among the coal mining process, if adopt traditional bearing can cause the isolating device trouble easily, sound isolation effect.

Furthermore, the two sides of the partition board are symmetrically provided with sliding chutes for bearing the expansion board. The expansion board can be pushed away conveniently, so that the stable direction is realized, and the deviation caused by the working environment can be avoided.

Further, the entire isolation device is coated with dust-proof paint. Because a large amount of dust can be generated in the coal mining process, the dustproof paint is coated to prolong the service life of the isolating device.
