Abstract
The utility model provides an unloading device for a coal mine main shaft. The unloading device comprises an inclined shaft rubber belt device and a coal conveyor; a funnel-shaped coal chute located under the head part of the inclined shaft rubber belt device is arranged above the coal conveyor; the upper port, located at one side directly facing the head part of the inclined shaft rubber belt device, of the coal chute is connected with a gate plate by use of a hinge; the upper end of the gate plate is erected on a supporting plate; a coal guide opening is formed between the upper port of the coal chute and the supporting plate; a coal unloader is arranged under the coal guide opening at one side; the coal unloader is arranged to form a right angle with the head part of the inclined shaft rubber belt device. The coal guide opening is opened and closed by virtue of the movement of the gate plate; when the coal conveyor is out of order, raw coal is directly fed into the coal unloader via the coal guide opening for transportation, and therefore, the damage, caused by the accumulation of the raw material in the coal chute, to the coal chute is avoided; the safety production and working efficiency of the main shaft is improved, and the working strength of workers is reduced.
Description
Technical field
The utility model relates to a kind of colliery equipment of unloading coal, and relates in particular to a kind of for colliery main shaft discharging gear.
Background technology
The raw coal of coal mining is all pooled in Bunker, and the raw coal in coal bunker is transported to aboveground again through inclined shaft sealing-tape machine, then enters and horizontally disposed belt feeder, be transported to coal preparation plant and carry out cleaned coal processing from the coal drop of its chain-drive section.During due to use, one is long; belt feeder there will be fault and shuts down suddenly; and now inclined shaft sealing-tape machine is still being worked; constantly take raw coal out of main shaft and cause the accumulation of raw coal; coal drop is caused to serious load; cause coal drop to be crushed out of shape or soldered softened, at this moment must carry out the raw coal being compacted in artificial conducting coal drop by workman, thereby come to such an extent that affect main shaft safety in production.If inclined shaft sealing-tape machine is shut down not in time, can cause a large amount of raw coal to trickle down go back to main shaft bottom, contaminated environment, and shovel coal and increased work capacity to work.
Utility model content
The utility model is exactly, in order to overcome the above problems, to provide a kind of for colliery main shaft discharging gear, prevents that raw coal from piling up and the coal drop that causes damages, and alleviates workman's working strength.
In order to achieve the above object, it is a kind of for colliery main shaft discharging gear that the utility model provides, comprise inclined shaft sealing-tape machine and coal conveyor, the funnelform coal drop that is positioned at inclined shaft sealing-tape machine chain-drive section below is located at the top of coal conveyor, described coal drop is positioned at the upper port that the is right against inclined shaft sealing-tape machine chain-drive section one side flashboard that has been connected through the hinge, and the upper end frame of described flashboard is located on stay bearing plate; Between the upper port of described coal drop and stay bearing plate, be provided with and lead coal mouth, be positioned at the side-lower of leading coal mouth and be provided with coal unloader; Described coal unloader and inclined shaft sealing-tape machine chain-drive section are at right angles arranged.
Further, the top of described flashboard is connected with driving cylinder, and described driving cylinder is electrically connected to the motor of coal conveyor by relay.
Further, described in, lead coal mouth and be positioned at inclined shaft sealing-tape machine chain-drive section parabola drop point place.
Relay in the utility model adopts moving fault relay, and during its coil no power, two contacts are closed, and after coil electricity, two contacts just disconnect.To drive cylinder to be electrically connected to the motor of coal conveyor by relay; when coal conveyor et out of order is shut down; the coil no power of relay; its two closings of contact connection circuit makes to drive cylinder to carry out work; drive hinge that air cylinder driven flashboard is connected with coal drop port along it to lateral movement in coal drop; and then shelter from obliquely the suitable for reading of coal drop, and will lead coal mouth and reveal.The raw coal that inclined shaft adhesive tape transports up from shaft bottom enters coal unloader and transports from leading coal mouth from portion, thereby has avoided raw material to damage coal drop, the safety in production that has improved main shaft inner accumulation of coal drop.While working on after the fault of coal conveyor is got rid of, coil electricity due to relay, its two contact disconnects, disconnected the pull up circuit that drives cylinder, cylinder contractile motion makes flashboard get back to original position, shelter from and lead coal mouth, the raw coal that inclined shaft sealing-tape machine transports up from shaft bottom enters coal drop, then drops in coal conveyor and transport.
So the utility model is by the motion of flashboard, reach folding and lead the object of coal mouth and coal drop upper port, when coal conveyor has fault, make raw coal directly from leading coal mouth, enter coal unloader and transport, thereby avoided raw material to damage coal drop inner accumulation of coal drop, improve safety in production and the work efficiency of main shaft, and alleviated workman's working strength.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation when coal conveyor is normally worked in the utility model.
Fig. 2 is structural representation during coal conveyor et out of order in the utility model.
In figure: 1-inclined shaft sealing-tape machine, 2-coal conveyor, 3-coal drop, 4-coal unloader, 5-hinge, 6-flashboard, 7-drives cylinder, 8-stay bearing plate.
The specific embodiment
A kind of for colliery main shaft discharging gear, comprise inclined shaft sealing-tape machine 1 and coal conveyor 2, the funnelform coal drop 3 that is positioned at inclined shaft sealing-tape machine 1 chain-drive section below is located at the top of coal conveyor 2, described coal drop 3 is positioned at a side upper port that is right against inclined shaft sealing-tape machine 1 chain-drive section and is connected with flashboard 6 by hinge 5, the upper end frame of described flashboard 6 is located on stay bearing plate 8 and is connected with and drives cylinder 7, and described driving cylinder 7 is electrically connected to the motor of coal conveyor 2 by relay; Between the upper port of described coal drop 3 and stay bearing plate 8, be provided with and lead coal mouth, described in lead coal mouth and be positioned at inclined shaft sealing-tape machine 1 chain-drive section parabola drop point place; Be positioned at the side-lower of leading coal mouth and be provided with coal unloader 4; Described coal unloader 4 is at right angles arranged with inclined shaft sealing-tape machine 1 chain-drive section.
As shown in Figure 1, during the normal work of coal conveyor 2, relay contact disconnects, and drives cylinder 7 not work, and flashboard 6 has sealed and led coal mouth, and the raw coal that inclined shaft sealing-tape machine 1 transports up from shaft bottom enters coal drop 3, then drops in coal conveyor 2 and transport.
As shown in Figure 2, during coal conveyor 2 et out of order, relay contact is connected, drive cylinder 7 work, drive flashboard 6 to move around hinge 5, and sealed the upper port of coal drop 3 and exposed and lead coal mouth, the raw coal that inclined shaft sealing-tape machine 1 transports up from shaft bottom directly enters leads coal mouth, then drops in coal unloader 4 and transport.
