Description

yCTPOi iCTBO TO MECHANIZED BOARD

There are known devices for a mechanized shield for the incineration of inclined mine workings, including a platform, trolleys, a rail track, a conveyor, stop devices and a block paver.

In these devices, the blocks are supplied to the block-laying unit with a nominal hoist, a shuttle carriage and a roller table, which does not allow production to occur at an angle of more than 2 °.

The proposed device differs from the known ones in that it is equipped with a mechanism for moving the trolleys and feeding the blocks to the block spreader, made in the form of a carriage with a turning beam fixed to it rotatably in two mutually perpendicular planes. This ensures penetration efficiency.

FIG. Figure 1 shows the on-display device at the time when the block carriages were located on the conveyor; in fig. 2 - placement of the equipment complex in the transverse section of the generation of a single-track pa section.

On the technological platforms J, which are articulated with each other and connected to the tunnel shield 2, there is a rail track 3, including single-track and double-track (warm-up) sections, with which the trolleys 4 and block 5 move.

On the track, locking devices 6 are installed to hold the trolleys and block cars in the desired position. Reloader 7, located on the upper beams of the front platforms, serves to load a wagon; to breed. A mechanism consisting of a movable carriage 8, a winch .9 with a friction pulley, a rope W and deflecting rollers is used to move the trolleys and feed the blocks.

The carriage 8 is provided with a turntable 12, which can move in vertical and horizontal iloscule, which makes it possible to use it to feed the blocks to the block spreader. On the carriage there is a gap of blocks of traveling wheels, each of which consists of three wheels located in the vertical and horizontal planes. This allows the carriage of the engine to drive rail to the rail irrespective of the direction of load on the turn beam. In addition, such a number of traveling wheels allows the kag-net to freely pass large joint gaps between the guide rails. These vases are required when driving curved workings.

the forms (along the shield) the carriage moves, and on the left side there is a passage for people. Both branches of Kanaia are at the same distance from the axis of the platforms. With this arrangement, in the case of penetration of curvilinear workings, one branch of the rope is lengthened, and the other is shortened by the same amount, which eliminates the possibility of breaking or weakening the rope.

The work involves two trains; one includes only trolleys, the other includes trolleys and block cars.

The device works as follows.

From the shaft of the shaft to the turnout, with the help of a self-propelled vehicle of the type PMK-2b, the composition of empty trolleys is delivered, which is attached to the carriage by means of a connecting cable 13 and is fed under the conveyor. As the breed loads, the composition moves to the warm-up. After loading, the trolleys occupy one track of the turnout, and the second track, which includes trolleys and block carts, is fed onto another track. This composition is attached to the carriage and fed under the conveyor. The PMK-2v self-propelled trainer takes the loaded trolleys and transports them to the trunk of the shakht.

After feeding the train under the blockage conveyor, they are held in place by a locking device, and the trolleys, as they are loaded, move to the warm-up. On the turnout, loaded wagons are held by a stopper.

the device, and the carriage moves to the blocks, unloading the blocks and feeding them to the shield block. For iodachi blocks to the block paver, the pivot beam is fixed at an angle a to the axis of generation so that the axis of the stackable block coincides with the axis of the block paver.

After unloading and installing the blocks, the empty blocks with a carriage are fed to the warm-up. At this time, the composition of the empty cars is fed to the free track clearance and the cycle repeats.

When driving horizontal workings, the carriage can simultaneously serve as a pusher. For this, its rotary beam is fixed in a position that is non-regular to the axis of production.

Subject invention

A device to a mechanized shield for conducting inclined and curved mine workings, including a platform, trolleys, a rail track, a conveyor, locking devices and a block paver, characterized in that, in order to ensure efficient penetration, it is equipped with a mechanism for moving the trolleys and feeding blocks to the block paver, in the form of a movable carriage with a swivel beam fixed to it rotatably in two mutually non-perpendicular planes.
