Description

The utility model relates to conveyors, in particular, to the connection of belts, and can be applied to conveyor belts used for transporting bulk and rocky materials over long distances.

Various connections of conveyor belts are known: for example, glued, vulcanized, as well as shell-type, articulated and bolted joints.

These compounds are often damaged due to their low tensile or abrasion strength, and their strength is below acceptable standards, in particular in the mining industry.

From the descriptions of utility models PL No. 53677 and PL No. 58750, there are known compounds for conveyor belts satisfying a number of quality requirements, however, when used for heavily loaded belts, their efficiency decreases.

The closest to the claimed utility model is a connection for tapes, consisting of upper and lower plates, which have two centrally located holes in the profiled, concave-convex oval end parts of the plates having the shape of a sector, and detachably connected by connecting bolts, which are fixed at one end in the holes of the bottom plate [PL No. 58750].

The adhesion of the conveyor belt in this design can destroy brushes and scrapers, as well as damage rubber drums.

The utility model is based on the task of creating the simplest, and therefore cheaper construction of the connection for belts, which would reduce the time of its installation to obtain optimal adhesion parameters of the conveyor belt, which would not destroy the brushes and scrapers even at high loads of the belts, and also would not cause would damage rubber drums and the mainline rollers carrying bulk and rocky material.

The problem is solved in that in the connection for tapes, consisting of a set of two profiled plates that have centrally located through holes in which the connecting element is located, the profiled plates have at least three profiled protrusions that are located on their inner surfaces, and the connecting element made in the form of a bolt, the head of which corresponds to the seat socket of the upper profiled plate.

Four profiled protrusions can be symmetrically located on the inner surfaces of the plates.

The profiled protrusions in a transverse cut have a shape close to the letter “U”.

The end of the bolt has a conical tip.

A thread can be made along the edges of the through hole of the bottom profiled plate.

A nut may be pressed into the hole in the lower profiled plate.

The utility model is illustrated by drawings.

figure 2 is a top plate in partial section, a view from the side;

figure 3 is a General view of the lower plate from the inside;

figure 4 is a bottom plate in partial section, a view from the side;

figure 5 is a General view of the connection for the tapes in the composition;

figure 6 - connection for tapes in the composition, view from the top.

The connection for tapes consists of the upper 1 and lower 2 profiled plates, which are square in shape with rounded corners and through holes 3, which are located in their central parts.

Four profiled protrusions 4 can be symmetrically located on the inner surfaces of the upper 1 (Fig. 1) and lower (Fig. 3) profiled plates.

The profiled protrusions 4 in cross section have a shape close to the letter “U”.

On the outer surface of the upper 1 profiled plate is a landing slot 5.

The upper 1 and lower 2 profiled plates are detachably connected using a connecting element 6.

The connecting element 6 is made in the form of a bolt with a thread cut on the side surface, which ends on one side with a head 7 with a cross cutout 8 (Fig.6), and on the other side with a tip 9 of a conical shape (Fig.5).

The profile of the head 7 of the connecting element 6 corresponds to the profile of the mounting socket 5 of the upper 1 profiled plate.

A nut (not shown) may be pressed in along the edges of the through hole 3 of the lower 2 profiled plate.

Mounting the connection for tapes can be carried out as follows:

First, the ends of the connecting tapes are brought closer to themselves, so that the tape is slightly stretched, and the end of the tape is cut at a right angle. After that, the ball of the tape, which corresponds to the length of the inlet, is cut and removed. Notch depth

is chosen in such a way that when the ends of the tapes are overlapped, the thickness of the joint is equal to the thickness of the tape. After laying the ends of the tapes “lap”, using the template at the junction of the tapes with a drill, make through holes 3, which correspond to the diameter of the connecting element 6. Then, through the openings 3, insert the connecting element 6, on which the upper 1 profiled plate is pre-worn. From the other side on the connecting element 6 put on the bottom 2 profiled plate and partially tighten. After mounting all components of the tape connection, they are finally tightened.

The claimed connection for belts has a simpler design, cheaper, allows you to quickly and reliably connect the belt at high loads, and also makes it possible to obtain optimal parameters for connecting the conveyor belt. The formation of three sharp protrusions on each of the flanges of the profiled plates does not lead to cutting tapes. The use of the connection for the tape according to the claimed utility model does not destroy the brushes and scrapers, and also does not cause damage to the rubber drums and the line of the rollers that carry bulk and rocky material.
