A gap is reserved between the upper countercurrent partition plate 1 and the middle countercurrent partition plate 2, and an upper layer belt passes through the gap; there is a space between the middle counter-flow baffle 2 and the lower counter-flow baffle 3, through which the lower belt passes.
Go up to articulate on the counter current baffle 1 and have a fly leaf 6, fly leaf 6 passes through rope 5 and is connected with hand calabash 4, and it is rotatory to drive fly leaf 6 through hand calabash 4, and the casing of hand calabash 4 is fixed on the wall body.
When the air door is used, the upper countercurrent partition plate 1, the middle countercurrent partition plate 2 and the lower countercurrent partition plate 3 are fixed on the wall of the air door according to the positions of the belts, so that the upper-layer belts can pass through the space between the upper countercurrent partition plate 1 and the middle countercurrent partition plate 2, and the lower-layer belts can pass through the space between the middle countercurrent partition plate 2 and the lower countercurrent partition plate 3.
When the belt normally discharges coal, the rope 5 pulls the movable plate 6 to rotate and open by rotating the hand-operated hoist 4, so that the normal coal discharging of the belt is ensured; when the belt stopped, the hand calabash 4 was rotated in the antiport, and under the effect of gravity, 6 antiports of fly leaf were closed, blocked the amount of wind. The requirement of roadway ventilation can be guaranteed under the condition that coal is not influenced, and dust in the roadway is effectively reduced.
The following steps: the upper countercurrent partition plate 1, the middle countercurrent partition plate 2 and the lower countercurrent partition plate 3 can be made of steel plates, so that the cost for purchasing a countercurrent device and the engineering quantity for removing a belt and installing a coal chute on a channel are saved, the cost and the investment of construction are saved, and great convenience is brought to production.
Further, the wall-mounted elevator further comprises a pulley, wherein the pulley is arranged on the wall body, and a rope 5 is connected with the pulley; when the pulley is not arranged, the hand hoist 4 needs to be arranged above the movable plate 6 so as to drive the movable plate 6 to rotate; however, the operation is inconvenient when the hand-operated hoist is arranged above the hand-operated hoist, so that the hand-operated hoist 4 can be connected with the rope 5 through the pulley by arranging the corresponding pulley, and the rope 5 is in an inverted U shape, so that the hand-operated hoist 4 can be arranged at a position lower than the movable plate 6, and the operation is convenient.

One end of the rope 5 is connected with the hand hoist 4, and the other end of the rope 5 passes through the first pulley 7 and the second pulley 8 to be connected with the movable plate 6. Therefore, the position of the hand-operated hoist 4 can be arranged at a place convenient to operate by arranging the pulley block, and the rope 5 can be prevented from falling off by arranging the two pulleys.
Above-mentioned hand block 4 can adopt among the prior art common structure can, hand block 4 has two-way self-locking function moreover, can prevent the unexpected rotation of fly leaf 6.
Further, although the hand hoist 4 in the prior art has a self-locking function, in order to avoid the failure of the self-locking mechanism and cause the movable plate 6 to rotate accidentally, the upper backflow partition plate 1 is provided with a limiting mechanism, and the movement of the movable plate 6 is limited by the limiting mechanism. After the movable plate 6 is opened, the position is limited through the limiting mechanism, and the movable plate 6 is prevented from being accidentally closed in the running process of the belt.
Furthermore, the limiting mechanism is a bolt 10, the bolt 10 is connected with the upper countercurrent partition plate 1 in a sliding mode, a sliding block 11 is fixed on the bolt 10, and a corresponding sliding groove 12 is formed in the upper countercurrent partition plate 1.
After the movable plate 6 is driven by the hand-operated hoist 4 to rotate upwards for opening, the bolt 10 is pushed to move, and the bolt 10 blocks the movable plate 6, so that the movable plate 6 is limited to rotate, and a limiting effect is achieved; when the movable plate 6 needs to be closed, the bolt 10 is pulled to move reversely, so that the bolt 10 does not block the movable plate 6 any more and does not limit the movement of the movable plate, and the movable plate 6 can be closed in a downward rotating mode by reversely rotating the hand-operated hoist 4.
Further, the slide block 11 is a T-shaped slide block, and the slide groove 12 is a T-shaped slide groove.
Further, although the arrangement of the bolt 10 can play a limiting role, when the position of the bolt 10 is arranged higher, the controller is inconvenient to slide; therefore, the wall-mounted lifting device further comprises a lifting lever 13 and a connecting rod 14, wherein the connecting rod 14 is fixedly connected with the plug pin 10 or the sliding block 11, the connecting rod 14 is provided with a connecting groove 15, one end of the lifting lever 13 can extend into the connecting groove 15 and can move in the connecting groove 15, and the other end of the lifting lever 13 is hinged with the wall. When in use, the driving lever 13 is pushed left and right to rotate so as to drive the bolt 10 to slide along the sliding groove 12.
Further, a handle 16 is disposed on the shift lever 13, and the shift lever 13 is driven to rotate by the handle 16.
Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
