Field of application of the invention

The invention relates to the design and arrangement of sliding and Schleißelnlagen to conveyors of all kinds to protect the sliding surfaces, supporting members and conveyor elements from premature wear.

Characteristic of the known technical solutions The known technical solutions of the attachment of sliding and Schleißeinlagen in chutes, chutes, continuous conveyor ο. ä.

Basleren mainly on gluing, welding or screw or combinations with each other.

In this case come as a deposit material metal sheets of different material grades or ceramic materials

Application.

In GB-PS 2194222 a tile wear plate for the lining of slides is shown, their shape and

Although possible Verlegungsvarianten ensure that the conveyed does not come into contact with the slide wall, but on the other hand assume that the holes for attaching the Kachelverschleißplatte to the sliding walls and the

Plate dimensions must be very tightly tolerated and very accurately manufactured, otherwise unwanted columns can

occur.

Particularly disadvantageous is the attachment of the plates with countersunk screws, as with the wear of the plates and the Screw heads wear out. As a result, not the entire plate thickness can be used as wear protection, because

after wear of the screw head, the screw shaft falls out and the plate is no longer held.

In GB-PS 2107288 a joined wear plate is protected, due to their numerous items very

consuming in their production. Since each wear plate must be screwed, the effort to prepare the chute body is very large.

With these just mentioned types of attachment, there are inevitably gaps between the inserts, which are very

unfavorable to the production process. On the one hand, there is no wear protection in the gap area and, on the other hand, these gaps can lead to considerable caking and accumulation of the conveyed material and as a result to blockages in the chutes or chutes.

In DE-OS 2508593 a tarpaulin is protected, which has a metallic support plate on the back of the Corners are provided with bolts, which the support plate on the chute or chute ο. β. fasten, One or more Aluminum oxide porcelain debris plates are attached to the backing plate by means of rubber adhesives. The Joints between the protective plates are partially filled by the rubber adhesive. Again, it must be stated

be that the technological effort to stick and burn the aluminum oxide plates on the support plates and the

Attachment of the support plates with screws on the slide body is very large and unwanted gaps between the Aluminum oxide plates are present, which ensure no uniform slippage of the transported material.

In the DD-WP106993 a design, arrangement and attachment of plate-shaped elastomeric wear parts for surface armor is protected, which is characterized in that elastomers wear material preferably hexagonal shape is glued or vulcanized on a fchenlich smaller steel sheet and this composite plate is welded onto the slide body. The composite panels are arranged so that the elastomeric wear material overlaps each other and thereby can be glued together during assembly. Since each composite panel welded and the elastomeric wear material must be glued, also here the technological preparation and manufacturing costs is very large. In addition, the interchangeability for repair purposes is not given. Other disadvantages with the o.g. Types of attachment of Schleißeinlagen result from the fact that in the welded Schleißblechen the degree of wear can be controlled and in most cases, the wear is recognized only when the slide wall itself has damage and that when screwed Schleikeinlagen no full utilization of the insert thickness is possible.

Object of the invention

The aim of the invention is the o. G. Disadvantages of the previously known solutions as far as possible to reduce and eliminate and to create new applications.

Explanation of the essence of the invention Object of the present invention is to provide a simplified design, arrangement and attachment of sliding and Schleißeinlagen, in addition to the usual Schleißeinlagen of sheet metal and ceramic and novel sliding and Schleißeinlagen Insert glass and develop new additional areas. According to the invention this is achieved in that two opposite sides of a sliding and Schleißeinlage not

perpendicular to the top and bottom, but inclined, i. thus wedge-shaped, are executed.

The sliding and Schleißeinlagen with threaded pins, which are attached to the body, has the top

(Sliding surface) of the sliding and Schleißeinlage a larger area than the bottom.

The sliding and Schleißeinlagen have no threaded pins, ie between the sliding and Schleißeinlagen with Threaded pin have a larger bottom than top. Due to the alternating arrangement of the sliding and wearing inserts with and without threaded pins, the clamping of sliding

and Schleißeinlagen only possible and thus half of the holes and preparatory work on the body can be saved.

The sliding and Schleißeinlagen made of sheet metal by means of a welded on the side threaded stud on the Body bolted. The sliding and Schleißeinlagen of glass or ceramic have on its underside a recess

wherein a verseltenes with a threaded pin sheet is glued. By this underlying the invention

Arrangement and attachment arise between the sliding and Schleißeinlagen no more columns and thus becomes

especially the problem of clogging of slides and the increased premature wear avoided.

When using the sliding and Schleißeinlagen of glass according to the invention as sliding surfaces under the conveyor belt in Aufgabestationen, Fördergutabstreicher, tables or on inner and outer gurtrelnigern o.a. is by moistening the Sliding insert optimally reduces friction and reduces wear on these assemblies. Ausführungsbelsplel

The invention will be explained in more detail below with reference to exemplary embodiments

 The accompanying drawings show

Fig. 1 and 2: combination of screwed and clamped sliding and Schleißeinlagen from sheet metal Fig. 3 and 4: combination of screwed and clamped slide and Schleißeinlagen glass Fig. 5: Arrangement of screwed and clamped sliding and Schleißeinlagen on the floor and to the

Side walls of a conveyor. On the, consisting of sheet steel, sliding and Schleißeinlage 1, with two opposite conical to each other

inclined sides, a threaded pin 2 is welded down.

The sliding and Schleißeinlage 3 with the same contours and dimensions as 1, but without a threaded pin 2 is

conversely, as the sliding and Schleißeinlage 1, d. H. with the larger surface down on the base 4, z. B.

(Slide wall) placed.

By means of three sliding and Schleißeinlagen with threaded pin 1 two sliding and Schleißeinlagen without threaded pins 3 on

the base 4 fixed and clamped.

The sliding and scarfing layers 5 made of glass or ceramic are in the same shape as the sliding and scarf layers Schleißeinlagen 1 made of sheet steel, only that they on their underside a recess (recess) 6, In the means of a Adhesive, a metal plate 7 is fixed with a threaded stud 2 welded thereto have. The sliding and Schleißeinlagen glass 8, the reverse between the sliding and Schleißeinlagen 5 on the base. 4

have the same dimensions and contours of the sides as these, but each have a smooth, flat top and bottom, i. without recess 6.

5 is the cross section of a slide 9, with screwed and clamped sliding and Schleißeinlagen 1 and 3,

which in this case have an edge bevel of 45 °, in particular. In this arrangement, three sliding and Schleißeinlagen 1 or 5 four sliding and Schleißeinlagen 3 or 8 are clamped over corner with three screwed. All these

Mounting options have the advantage that they always take place without gaps. When using sliding and wear inserts

made of glass in slides o.a. the service life is increased up to the 1of the previously used materials.

When using glass plates as sliding pads for a conveyor belt is by constantly moistening the glass plates

The friction is greatly reduced and the wear also drastically reduced.
