Description

The invention relates to a conveyor belt, namely, devices for preventing the cuts of the conveyor belt.

A device for maintaining the conveyor belt in the place of its loading is known, which includes a table inclined under the lena, mounted on shock absorbers of the pillars, which are fixed on the conveyor stand 1.

The constructive solution of the device will prevent foreign objects from cutting the conveyor belts, but the lack of adjustment of the installation angle of the table wing and adjustment of the gap between the belt and the table when installing the device on an existing conveyor and during operation reduces the efficiency of the device and increases the wear of the conveyor belt. as in the absence of a gap, the belt loops around the table, and with an increased gap there is a danger of cutting the conveyor belt.

. The device closest to the invention is a device for maintaining the conveyor belt at the place of its loading, comprising wings connected by one end with racks to the frame and resting the other edge on the bottom, mounted by shock absorbers on the frame, connected by supports 2.

The disadvantage of this device is the absence of installation and technological adjustments. In factories, conveyors of the same type along the width of the belt have different designs. So, for example, the angle of inclination of the extreme rollers in the hollowed roller support varies from 15 to 30 ° C. In a wide range, the height also varies from the base of the roller to the line of the rim of the drum. When replacing the conveyor belt, as well as during operation, the elasticity and the conveyor belt tension change, which leads to a change in the gap between the table and the belt, which reduces the efficiency of the device.

The aim of the invention is to increase the efficiency of the device by adjusting the gap between the belt and the bottom of the wings.

This goal is achieved by the fact that in the device for maintaining the conveyor belt at the place of its loading, including the wings, connected by one edge of the uprights c. frame and supported by another edge on the days-, shche, mounted by shock absorbers on the frame connected by supports with the stand, the supports are made in the form of eyelets with slots fixed to the ends of the frame and connected with the stand with the possibility of turning the cranks with necks located in the slots of the eyes, The slots of the lugs at one end of the frame are made wider than the slots of the lugs at the other end of the frame by the amount of the crank eccentricity, and the legs are made of two parts interconnected with the possibility of moving one relative to the other.

FIG. 1 shows a device for maintaining the conveyor belt at its loading point, side view; in fig. 2 - the same, cross section; in fig. 3 - unit for connecting the parts of the rack.

A device for maintaining the conveyor belt at its loading point is set under

 a tape 1 on a stand 2 conveyors and a joke from frame 3 with lugs 4 and shock absorbers 5 on which the bottom 6 lies freely. Wings 7 are fixed with the help of fingers 8 with a distance stop 9 on composite

5 racks made from the top and bottom. In the upper part of the rack 10 there are grooves 11 for setting the required angle of inclination of the wings, the curved roof has necks 12 and cheeks 13 installed in the brackets of the brackets 14, the necks have clamps 15 through 0 for moving the table. The locking nuts 16 are mounted on the fingers 8, the nuts 17 are mounted on the ends of the crank.

The mounting adjustment and operation of the device is carried out as follows.

In the place of loading, the rollers are removed, and a device is mounted on the conveyor base 2. By moving the fingers 8 in the grooves 11 of the upper parts of the uprights 10, the initial inclination of the wings 7, corresponding to the grooves of the roller supports of the conveyor, is established and fixed by tightening the composite uprights with the nuts 16 to the distance stops 9 fingers 8. The frame 3 is installed with eyelets 4 on the necks 12 of the cranks coaxially with mounted tape 1

using clamps 15 transverse movement of the table. When the conveyor belt 1 is loaded, the required inclination is set, and the gap between the bottom 6 mounted on the shock absorbers 5 and the tape 1 by turning the cheeks 13 is fixed by a crank 17 in the brackets of the brackets 14. At a steady flow of cargo of a specific particle size distribution to the tape 1, the bottom 6 s The wings 7 do not touch the tape due to the presence of an exposed clearance. When the load is lost, after loading, as well as when large pieces of material and mass are hit, dynamic loads arise, the tape briefly touches the wings 7 and the bottom 6, and the shock absorbers 5 damp these n iKOBbie loads.

0 If extraneous sharp objects fall into the flow (metal scrap, etc.), bottom 6 prevents penetration of the tape and jamming of sharp objects behind any conveyor element (rollers, roller stand), which prevents the cutting of tape 1. During operation, elasticity and the tension of the belt changes, the gap between the belt 1, the bottom 6 and the wings 7 disappears.

To prevent belt wear and stop of the conveyor, clearance adjustment is again performed.

The implementation of the device with the adjustment of the required tilt of the wings and the bottom,

adjustment during operation of the gap between the belt and the bottom of the wings expands the possibility of its use, allows to increase the service life of the belt, reduces downtime of the conveyor.
