DEVICE FOR REPAIR OF BELT CONVEYORS

one

The invention relates to devices used for the mechanization of repair and installation operations in conditions that impede the use of lifting equipment, such as in a mine.

Apparatuses for repairing belt conveyors are known, which comprise a single-drum winch with a load-carrying element and a crank.

The purpose of the invention is to fix the device on the cable bed of a belt conveyor.

This is achieved by the fact that the drum of the winch is made with a cutout along its generatrix, and the axis of the drum is made in the form of an eccentric half-sleeve.

FIG. 1 schematically shows the proposed device; in fig. 2 - fixing the device on the cable bed of the conveyor; in fig. 3 - the same, side view.

The device contains a double-rib drum / equipped with a longitudinal notch, the width of which is slightly larger than the diameter of the rope 2 of the conveyor belt, the crank 5 and the load-carrying rope or chain 4. An eccentric semi-sleeve 5 passes through the drum, when turning around its axis, the closing recess of the drum. A loop 6 is welded to the end of the half sleeve, which is joined to the loop 7 by turning the half sleeve. On the drum side there is

eye 8. The load-carrying element clings to the eyelet with hook 9. The collar has a middle hole 10 and an end hole //. A pin is inserted into the latter to prevent the knob from falling out of the loops.

The device works as follows. The drum and the eccentric sleeve 5 are mutually rotated so that the neckline opens to its full width. Then the drum is cut into the rope 2 of the conveyor roll, the sleeve 5 is rotated by 180 °, and the knob 3 is passed through loops 6 and 7. By hooking the load-carrying element 4 to the procurator 8, various repair operations can be performed, while the drum is rotated on the rope, on its axis.

To lift the tape above the roller support, the cable is passed under it, clings to the opposite rope and is pulled.

At the same time, the upper and lower branches of the tape are raised.

To shrink or overlap the tape, the tape is covered with a cable and pulled up with a drum. For hanging

or remove the rollers from the rope, the cable is attached to it and is wound up or wound from the drum. When straightening the conveyor belt, the sliding part of the rack is raised up with the same cable by means of additional

pipe supports, sleepers, etc. The subject of the invention The device for repairing belt conveyors, containing a single-drum winch with a load-carrying element and a crank, is distinguished by 5

 ff

In order to secure the device on the cable bed of the belt conveyor, the drum of the winch is cut with its shape, the axis of the drum is in the form of an eccentric half-sleeve.
