Abstract

The invention relates to conveyor engineering, in particular, to inclined belt conveyors. It is intended for use as a braking device during the reverse movement of the belt with a load during emergency stops of the conveyor. The goal is to increase the operational reliability of the device and reduce tape wear. The device includes a roller (P) 1 with an axis 2 installed in the groove 3 of the rollers 4. It is installed on the hinge 5 attached to the conveyor's position and can be rotated in the direction opposite to the direction of movement of the conveyed belt (L) 8 and has a stop 7. On The conveyor 6 is placed in front of the roller 4 and a vertical support (VO) 3 is installed with a longitudinal guide cut 14. The braking elements 9 are attached to the brackets 11 and 13. They are made as installed with the possibility of longitudinal and transverse movements relative to the BO 13 sectors. The working surface of the latter is lined with friction material. In the event of an emergency in case of breakage of L 8 or its reverse course, under the influence of friction forces between L 8 and P 1, axis 2 moves in a groove 3 of the upper part of the roller support 4. Roller support 4 rotates on hinge 5 to the left, and surface P 1 comes in contact with the friction surface 10 of the braking element 9 fixed on BO 13. Stop, P 1 inhibits L 8. 1 Cpl-ly, 4 ill.

The invention relates to a conveyor construction, in particular to inclined belt conveyors, and is intended for use as a braking device during reverse movement of a belt with load during emergency stops of the conveyor.

The purpose of the invention is to increase the operational reliability of the device and reduce belt wear.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 is a section. Л-А in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 — node I in FIG. 1. A device for trapping the conveyor belt contains a roller I with an axis 2 installed in the groove 3 of the upper part of the roller 4. In the lower part of the roller 4 is mounted on the hinge about, attached & pt to the 6 of the conveyor, and has a stop 7, turning the roller 4 4 1 cent 8. The braking element 9 is made in the form of a sector, the working surface KOTOpoi o is lined with friction material K), for example rubber, and has crown 11, in which the jaws of the notches 12 are made 12. The braking elements 9 are fixed by kropts1teyn 1 ver- tikalpoy 1 to the support 13, which in the upper part also has guide recesses 14. The support 13 prikreplepa stava bolt 15 to the conveyer 6.

The device works as follows.

During the brake operation of the conveyor but the material is transported in nap1), the auger arrow (fig. 1) under the action of friction between lepta 8 and roller 1 axle 2 in the groove, the upper part of the roller supports 4 is displaced in Kpaiinee right position (fig. 4), - on the roller 4, the 4-pa joint of the hinge 5 is turned to the right by a certain angle, while yntjp 7 limits its further rotation. When the roller 1 is wrenched under the action of the force of the pulley on the tape 8, the ro-picoopor 4 is rotated to the right to minimize the resistance to the movement of the tape 8.

In the event of an emergency when the tape breaks or is reversed under the action of friction between the tape 8 and roller 1, axis 2 moves into the groove 3 of the upper part of the roller 4 and causes it to turn on the hinge 5 to the left. In this case, the surface of the roller 1 comes into contact with the friction surface 10 of the brake element 9 until it stops. When you stop the roller 1 increases the power of friction between the roller 1 and the tape 8, causing it to brake and then stop (Fig. 1-3).
