The invention relates to a conveyor transport, namely the steeply inclined belt conveyors.

Known steeply inclined belt conveyor, comprising a support frame with guide rails for moving the chassis trucks, which are carrying the tape, the envelope of the drive and tension drums, and pivotally connected to the chassis of the bogie beam with gruzoperevozki partitions that are mounted on the traverse with the possibility of contact with the load-carrying surface of the belt. Beam made telescopic. They have limited rotation around its axis. This provides a adjust to any misalignment of the walls into position in the loading area of the conveyor [1].

The disadvantage of this conveyor is the inability cleaning tape from the adhered particles cargo simple mechanical means, and the fall of the tape with cargo in case of emergency its breakage.

the envelope holding the drive and tail drums endless conveyor belt, on the sides which are uniformly attached charms, each of which is provided with rollers rolling on the established on both sides of the conveyor rails and pivotally connected with pendants gruzoperevozki partitions. Each of the suspensions in the lower part provided with two projections, which use the fingers and the sleeve with a gap mounted two rigidly mounted on the bushing plate, between which is fixed to rotate in the plane perpendicular to the longitudinal axis of the conveyor, gruzoperevalka partition, which is pressed under the action of gravity on the freight branch of the pipeline to the working surface of the tape, and running branches diverging from the tape, freeing it for cleaning. Gruzoperevalka partitions are made of elastic material [2].

The disadvantage of this pipeline is that console mount elastic gruzoperevalki partitions suspensions denying them the necessary rigidity and ability to hold the load on the ribbon. This reduces the pipe at high angles of slope. In addition, if the alarm tape possible injury to operating personnel. The lack of pipeline and in that case briansuda. In this position it can cause breakage and other moving this guide suspensions. This can lead to failure of the pipeline.

Object of the present invention is reliable movement of cargo on steeply inclined road.

This goal is achieved by the fact that the proposed device according to the invention contains envelope drive and tail drums endless tape on the sides which are uniformly attached charms, each of which is provided with two rollers rolling on the established on both sides of the conveyor rails and pivotally connected with pendants gruzoperevalka partitions.

New in the claimed invention is that gruzoperevalka partitions are made in the form of elements, capable of changing its spatial curvature, primalsense under the action of gravity on the freight branch of the pipeline to the working surface of the tape, while the carrying capacity Gruzovaya partition is determined based on the weight of the load branches tape and angle of inclination of the conveyor, i.e., must be defined by the ratio of

< / BR>
where N is the carrying capacity Gruzovaya partitions, N.;

n - factor plannig to the longitudinal axis of the conveyor, which each suspension connected with pendants opposite side of the tape;

- the angle of the conveyor, hail.

Defined based on the proposed load-carrying capacity gruzoperevalki partitions guarantees them from destruction and the fall of the tape with cargo down in case of emergency its breakage, which increases the security service and the reliability of the pipeline. In addition, in the case of fastening to the belt of one of the suspensions of the latter being connected gruzoperevozki partitions with other pendants, retains its position and does not violate the mode of movement of the tape. This ensures reliable operation of the pipeline. Each pendant is connected with pendants opposite sides of a conveyor belt.

Such gruzoperevalka partitions, adapting to the curved surface of the tape under the action of its own weight and cargo to securely hold the load on the inclined belt, which increases the reliability of operation of the conveyor at high angles of slope. The length of the elements is such that flattened parts of the tape they take rectilinear shape. In this tensioned position they are nearly touching the working surface of the tape and didn't hinder her eyes the

When carrying out the invention may be obtained from the technical result consists in the fact that applied in the proposed pipeline gruzoperevalka partitions in the form of carnerosana with pendants elements with spatial flexibility to ensure reliable operation of the pipeline at high angles of slope and defined based on the proposed load-bearing capacity of the walls increases the security service of the pipeline.

In Fig.1 shows a side view of the steeply inclined conveyor with suspension ribbon of Fig. 2 - view And on top of working branch of the conveyor of Fig.3 - view B bottom at idle branch of the conveyor of Fig.4 shows a cross section of the linear part of the pipeline (section b-b of Fig.1).

Steeply inclined conveyor with hanging ribbon includes installed on poles 1 and 2 of the frame of the conveyor drive 3 and the terminal 4 of the reels on which is placed the endless belt 5 driven by the actuator (Fig.1). On the sides of the conveyor belt 5 is uniformly fixed right and left suspension 6, provided with the upper 7 and lower 8 supporting rollers (Fig.2) based with the possibility of free rolling on tubular rails 9. To suspensions pivotally mounted gruzoperevalka peotonix circuits. Each pendant is connected with pendants opposite side of the conveyor belt (Fig.2, type a). Length gruzoperevalki partitions such that flattened parts of the tape they take a rectangular shape (Fig.3, view B).

The pipeline works as follows. When a rotation with drive drive pulley 3 tape 5 is attached to a forward movement (to the right in Fig. 1). When this tape 5 carries attached to its sides charms 6 (Fig. 4) that by them the upper 7 and lower 8 support rollers roll freely on the tubular guide 9 (Fig.4). A hinge mounted on the suspension gruzoperevalka partitions 10 (Fig.4) adapted to the curved surface of the working branch of the tape under the action of its own weight and the load (Fig.4). In this position gruzomateriala partitions 10, Nativas as flexible strands, preventing sliding of cargo on an inclined belt. When vypolazhivaniem tape at idle branches (Fig.2) gruzomateriala partitions take rectilinear form, relate to the working surface of the tape and prevent the treatment from the adhered particles of known cargo, including, and mechanical means.

In the case of the Avars is Oh according to the expression (1), not destroyed and hold the tape is loaded on the drum 3 and 4, preventing it from falling down with the load and injury to operating personnel.

Technical and economic advantage of the invention lies in the fact that in the proposed conveyor pivotally connected with pendants gruzoperevalka partitions are made in the form of elements, capable of changing its spatial curvature, effectively prevent the sliding of the cargo on the tape. It helps to transport cargo at large angles of inclination of the conveyor. Being extended in a straight line and located directly at the surface of the blank branch tape, gruzoperevalka partitions do not interfere with the cleaning tape with the aid of known devices. Gruzoperevalka partitions, having a load capacity specified by the proposed expression (1), hold the tape on the reels during a disaster its breakage, which reduces the risk of injury to personnel and reduces the cost of restoring the health of the pipeline.
