The invention relates to a tunnel head used in the mining industry when driving vertical and steeply dipping workings.

The famous tub containing a suspension with a clamp and a cargo loop 1 attached in the lower part of the tub is known.

The disadvantage of this bucket is the scattering of cargo during emptying and the presence of considerable free space above the place of unloading.

Also known prokatcheskaya tub, containing, and the suspension and attached at the bottom of the tub cargo loop 2.

This bucket is raised above the discharge level and attached to its cargo loop is a flexible link of limited length, the other end of which is located at the root. During the return stroke, the bond will be held up by the bucket behind the bottom and the tub is overturned, discharging the rock.

The disadvantage of this tub is that, in order to ensure its unloading, it is necessary to have considerable free space above the unloading point.

The purpose of the invention is to provide unloading in cramped conditions.

This goal reaches 1; 1 by the fact that the tunnel head containing the suspension and the cargo loop attached at the bottom of the tub is equipped with grip flanges that are hinged on board at its upper edge.

FIG. 1 - the position of the tub when it engages with a punched trolley; in fig. 2 position of the tub during unloading; in fig. 3 - grip attached on board the tub.

The projectile tub 1 contains a suspension bracket 2 and a cargo loop 3 attached to its lower part. On board the bucket, grips 4 are mounted at its upper edge. 7 winches placed on the carriage 8, which is mounted on the monorail 9. The monorail is housed in a supplying horizontal excavation, equipped with paths for the shunting trolley 10 and the stops 11.

Claims (2)

Breeding is carried out as follows. The loaded tunnel bucket 1 is lifted and along the monorail 9 is moved to the mine trolleys 10 installed in the inlet horizontal working in the loading zone. Then, when lowering the tub, clutches 4 are brought into contact with one of the mine trolleys. Thereafter, the tubular suspension 2 is uncoupled from the rope 7, and the rope 7 is attached to the cargo loop 3. By pulling the rope, the tub is tilted around the axis of the hinge 6 through the side of the saddle trolley until the rock is poured. To prevent the trolleys from overturning in the area of their loading, stops 11 are installed. The use of the invention in the mining industry will improve the safety of work, since rock overload is carried out not at the work site, but away from it. In addition, the length of the monorail, you can load multiple trolleys without performing shunting work on their rearrangement. This invention will also simplify the design, because Tilting of the loaded bucket is carried out with the help of a lifting winch and there is no need to install unloading curves and guides. Formula of the invention A sinking tunnel containing a suspension and a cargo loop attached at the bottom of the tub, characterized in that, in order to ensure unloading in cramped conditions, it is equipped with grips that are pivotally mounted on board at its upper edge.
