Abstract
The utility model discloses a pneumatic interlocking anti-protrusion baffle, which comprises a pulley and two ventilation walls, wherein a baffle is hinged with the ventilation walls and is connected with a steel wire rope; and a telescopic cylinder is arranged on the steel wire rope. The steel wire rope is driven to move by utilizing the telescopic cylinder, so that the baffle is opened and closed, manual operation is not required, and the opening angle of the baffle can be well controlled. In addition, a power switch is arranged on a piston rod of the telescopic cylinder, so that the power supply of a scraper conveyer can be controlled, the conveyer can operate only when the baffle is opened, and the phenomenon that the baffle is damaged due to misoperation can be avoided.
Description
Technical field
The utility model relates to the transport in a kind of colliery, is specifically related to the retaining device that passes through when a kind of conveyer moves.
Background technology
At high gas projecting mine, control gas each safety device outstanding and the minimizing disaster all seem extremely important.When outstanding area employing conveyer is transported coal, cause distinguished and admirable reverse to cause disaster for preventing that gas is outstanding, the wind-tunnel that passes from brattice at conveyer is provided with the baffle plate of ability switch together.Its main method of operating is following: when the needs conveyer turns round, open the protrusion-dispelling baffle plate, conveyer at this moment can run well; When shutting down conveyer, the protrusion-dispelling baffle plate is put down, recover its brattice and normally act on.Existing protrusion-dispelling baffle arrangement is as shown in Figure 1; Mainly form, need the folding of manually-operated pulling counterweight control baffle plate in the time of operation, the bothersome effort of this mode of operation by baffle plate 3, wire rope 4, pulley 6 and counterweight 5; And the standard of opening of baffle plate is not easy control; In the equipment operation process, the baffle plate of stressed vibrations is landing voluntarily sometimes, and generation causes the accident.
The utility model content
The technical problem that the utility model will solve is to take a lot of trouble effort and have unsafe factor when having the operation of protrusion-dispelling baffle plate now, and a kind of simple and easy, safe pneumatic type interlocking protrusion-dispelling baffle plate of operating is provided.
The technical scheme of the utility model realizes in the following manner: a kind of pneumatic type interlocking protrusion-dispelling baffle plate, comprise pulley and two brattices, and be hinged with baffle plate on the brattice, baffle plate links to each other with wire rope, and wire rope is provided with telescopic cylinder.
The piston of said telescopic cylinder is provided with power switch, the power supply of power switch control drag conveyor.
The utility model utilizes telescopic cylinder to drive the wire rope motion, and then has realized the folding of baffle plate, does not need manually-operated and can well control the angle of baffle plate folding.In addition, the power supply that power switch can be controlled drag conveyor is set on the piston rod of telescopic cylinder, conveyer can move when having only baffle plate to open, and can avoid the phenomenon that causes baffle plate to damage because of operate miss.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 2, a kind of pneumatic type interlocking protrusion-dispelling baffle plate comprises pulley 6 and two brattices 2, is hinged with baffle plate 3 on the brattice 2, and baffle plate 3 links to each other with wire rope 4, and wire rope 4 is provided with telescopic cylinder 7.
The piston of said telescopic cylinder 7 is provided with power switch, the power supply of power switch control drag conveyor 1.Magnetic switch during said power switch.
In the utility model, constructor and baffle plate do not come in contact, and the switch of directly controlling telescopic cylinder carries out mechanically actuated and gets final product, and tighter when making the baffle plate closure, protrusion-dispelling is effective.In addition, because baffle plate 3 need be installed 2, the link wire rope 4 of one of them baffle plate 2 need pass brattice 2, and is not frayed for the protection wire rope, on brattice, penetrates 1 cun steel pipe in advance, and wire rope is passed from its steel duct.
The utility model operation sequence is following: during startup, stir the telescopic cylinder switch, by telescopic cylinder 7 controls baffle plate 3 is opened to the appropriate location; This moment, power switch was closed; At this moment be available operation start drag conveyor 1, when not needing drag conveyor 1 operation, should make drag conveyor out of service earlier; Put down baffle plate 3 again, it is closed.Having avoided occurring putting earlier baffle plate has a power failure etc. again and to draw the incident of damaging baffle plate to take place easily.
