The invention relates to a lifting machinery industry, and specifically to belt covers used in the mining industry.

The aim of the invention is to increase the reliability of the operation of the conveyor by reducing the dynamic loads on its travel wheels.

FIG. 1 shows the end of the belt conveyor, general view; in fig. 2 - view L in fig „1; figs 3 and 4 are disks, general view, embodiments.

The belt conveyor consists of a load-carrying belt placed on the transverse cross members 1 with the running wheels 2 along their condes. Traverses. 1 are connected to each other by a depot body 3, enveloping the sprocket 4 on the condom sections, mounted on the axes x 5,

The running wheels 2 are mounted on the upper 6 and lower 7 guides. Along the axles of the axle 5, transition elements are installed, made in the form of discs 8, which function as brake elements. Wheels 8 interoperable: from its surface to the surface. when the running wheels 2 run around them, the kondew 4 is rolled around them. The discs 8 are lined with elastic frictional material 9 (Fig. 2),

The disks 8 can be made entirely of elastic material (Fig, 3),

FIG. Figure 4 shows an embodiment of a disk 8 in the form of a hub 10 rigidly fixed on the axis x 5 of one of the sprockets, the rim 11 lined with frictional material and the elastic element 12 of the twist connecting them.

The conveyor works as follows.

When the conveyor operates, the running wheels 2 move along the guides 6 and 7 with the linear speed V, and the angular rotation speed of the running wheels along the lower guide 7 Wj., W. After finishing the movement along the lower direction (with the 7, the running wheels 2, with their surface of the katani, enter into the zone ™ action with the surface of the wheels 8, performing portable dvizhenie with an angular velocity (-W (j), At

The running wheels of the cam 8, pressed against the diset, are relative, having an angular velocity (the absolute angular velocity is W (, -W4), bends around the sprocket 4 and

They are driven to the top of the track 6, accelerating on it to the required angular velocity in the opposite direction (Fig. 1).

Similarly, work occurs when the conveyor moves in the opposite direction (when the traveling wheels move from the upper guide 6 to the lower 7).

The disk 8 (Fig. 3) works as follows.

 The kinetic energy of the drive wheel 2, when interacting with the disk, transforms into the potential energy of the torsional deformation of the elastic disk.

After stopping the wheel 2 relative to the disk, the potential energy of torsional deformation is spent on spinning wheel 2 in the opposite direction. In order to synchronize the operation of the elastic brake disc 8, its rigidity is determined by selecting the number and diameter of the holes in it.

This ensures a smooth. unstressed transition of the traveling wheels 2 from one guide to another.

When the brake disc 8 (FIG. 4) is operating, the energy of the traveling wheel 2 is stored in elastic elements 12. Synchronization of the transition of the traveling wheels 2 from the guide to the guide is carried out by selecting the stiffness of the elastic torsion elements 12.

Lining the friction material of the rim 11 prevents slippage of the wheel 2, which increases the speed of the conveyor.

The proposed conveyor allows braking and smoother acceleration of the conveyor wheels by changing speeds when moving from one track to another, moving the conveyor in any direction, which reduces wear on the travel wheels and increases rolling bearing durability.
