Abstract

The utility model discloses a conveying belt which comprises an upper layer, a strength layer and a lower layer, wherein the upper layer and the lower layer are located on two sides of the strength layer respectively, the strength layer is of a single-layer structure, and the thickness of the upper layer differs from the thickness of the lower layer. According to the conveying belt, a single-layer canvas structure is adopted, laying and delaminating phenomena occurring in a using process of the strength layer of a multi-layer structure are eliminated, the service life of the conveying belt is prolonged, the weight of the conveying belt of the same strength specification is greatly reduced, and therefore the purposes of energy conservation and emission reduction are achieved.

Description

A kind of load-transfer device

Technical field

The utility model relates to a kind of load-transfer device, is specifically related to a kind of degree of utilization height, long service life and energy-saving and emission-reduction load-transfer device.

Background technology

At present, the general load-transfer device that all adopts as shown in Figure 1 of employed industrial load-transfer device on the market, the rubber layer that comprises ground floor 1 and the 3rd layer 3, and at the strength layer 2 between 1 and the 3rd layer 3 for the first time, described strength layer 2 is multi-layer compound structure, and the subject matter that the strength layer 2 of this multi-layer compound structure exists is: the tension force of each interlayer is inhomogeneous, causes strength loss easily, in use occur the layering delamination easily, reduce the service life of load-transfer device.

The utility model content

The purpose of this utility model is to provide the load-transfer device of a kind of intensity height, not delamination.

The technical solution of the utility model is, a kind of load-transfer device comprises upper strata, strength layer and lower floor, and described upper strata and described lower floor lay respectively at the both sides of described strength layer, and described strength layer is single layer structure, and the thickness of described upper strata and described lower floor is different.

In preferred embodiment of the utility model, described strength layer is individual layer canvas structure.

In preferred embodiment of the utility model, described upper strata and described lower floor are rubber layer.

In preferred embodiment of the utility model, the thickness of described upper strata and described lower floor is than being 1-10.

In preferred embodiment of the utility model, the thickness on described upper strata is 3-15mm.

In preferred embodiment of the utility model, the thickness of described lower floor is 1-5mm.

In preferred embodiment of the utility model, the width of described load-transfer device is 100-2500mm.

In preferred embodiment of the utility model, described upper strata and described lower floor directly vulcanize bonding with described strength layer respectively.

Described in the utility model is a kind of load-transfer device, adopt individual layer canvas structure, solved the layering delamination that the strength layer of multiple-structure in use occurs, improved the service life of load-transfer device, greatly reduce the deadweight of powerful specification load-transfer device of the same race, thereby realize the purpose of energy-saving and emission-reduction.
