Description
Technical field
The utility model relates to a kind of elevator belt, relates in particular to a kind of high-temperature-resistant steel wire wire rope core elevator belt.
Background technology
Elevator belt is widely used in the closely vertical mass transport such as building materials, mine, harbour, iron and steel, and both convenient and swift, production efficiency is high again, is the necessary means that modernization material in enormous quantities is carried continuously.
At present, the resistance to effect of heat of general fire resistant hoisting belt is bad, service life is short, its major cause is in use, the heat of high-temperature material is easily rapidly to the band internal delivery, this just causes the easy aging breach of rubber cover of band, and the glue-line of band and skeleton wire rope core break away from, cause with the cripetura in service life.
Therefore, be necessary prior art is done further improvement.
Summary of the invention
The purpose of this utility model is to provide the tectal aging breach of a kind of effective prevention and heat of high temperature to the high-temperature-resistant steel wire wire rope core elevator belt with internal delivery.
For reaching aforementioned purpose, a kind of fire resistant hoisting belt of the utility model, it comprises anti-tear layer, lower anti-tear layer, described anti-tear layer with lower anti-tear layer between the core glue-line and be wrapped in the evenly distributed longitudinal steel wire wire rope cores of in described core glue-line some, wherein said anti-tear layer top is provided with thermal insulation layer, is provided with lower thermal insulation layer below described lower anti-tear layer.
According to an embodiment of the present utility model, the thickness of described upper thermal insulation layer and lower thermal insulation layer is respectively 1-10mm.
the beneficial effects of the utility model: compared with prior art, a kind of high-temperature-resistant steel wire wire rope core of the utility model elevator belt, by pasting one deck thermal insulation layer above upper anti-tear layer with below lower anti-tear layer, make coefficient of thermal conductivity reduce, and then effectively stop heat to the elevator belt internal delivery, and upper thermal insulation layer of the present utility model and lower thermal insulation layer adopt and are mixed with asbestos fiber, the ethylene propylene diene rubber of aramid fiber short fibre and adhesives, the aging breach that can effectively stop glue-line, the aging disengaging of protective core glue-line and Steel cord, extended the life-span of load-transfer device, and increased the brute force of elevator belt, reduced the damage rate of load-transfer device, reduced productive costs, improved production efficiency.The heat resisting temperature of elevator belt of the present utility model can reach more than 180 ℃, can extend 2-3 service life doubly.
Description of drawings
Fig. 1 is the structural representation of a kind of high-temperature-resistant steel wire wire rope core of the utility model elevator belt.
In figure, the upper thermal insulation layer of 1-, the upper anti-tear layer of 2-, 3-core glue-line, 4-Steel cord, anti-tear layer under 5-, thermal insulation layer under 6-.
The specific embodiment
See also Fig. 1, the structural representation of a kind of high-temperature-resistant steel wire wire rope core elevator belt that it provides for the utility model.As shown in Figure 1, a kind of high-temperature-resistant steel wire wire rope core elevator belt in the utility model, some evenly distributed longitudinal steel wire wire rope cores 4 during it comprises anti-tear layer 2, lower anti-tear layer 5, the core glue-line 3 between upper anti-tear layer 2 and lower anti-tear layer 5 and is wrapped in described core glue-line 3.Laying depth is the upper thermal insulation layer 1 of 1-10mm above upper anti-tear layer 2, laying depth is the lower thermal insulation layer 6 of 1-10mm below lower anti-tear layer 5, by above upper anti-tear layer 2 and lower anti-tear layer 5 below lay thermal insulation layer 1 and lower thermal insulation layer 6 can effectively stop the heat of material to the elevator belt internal delivery.In this embodiment, the thickness of described thermal insulation layer 1,6 is 1-10mm, and in other embodiments, the concrete thickness of this thermal insulation layer 1,6 can be decided according to the temperature of outside material and the structure of elevator belt self.
According to preferred embodiment of the utility model, described upper thermal insulation layer 1 adopts the ethylene propylene diene rubber that is mixed with asbestos fiber, aramid fiber short fibre and adhesives to make with lower thermal insulation layer 6.Described in the utility model, asbestos fiber is preferably chopped fiber, and its length is 1-5mm, and this is because chopped fiber is easy to mix.The utility model is when being mixed into ethylene propylene diene rubber with asbestos fiber, aramid fiber short fibre and adhesives; because the asbestos fiber coefficient of thermal conductivity is low; can effectively stop heat to internal delivery; the peel strength that aramid fiber short fibre can improve sizing material can effectively stop the aging breach of anti-tear layer and lower anti-tear layer; the aging disengaging of protective core glue-line and Steel cord; and then extended service life of load-transfer device, and the utility model processing is simpler, has reduced productive costs.
The technological process of production of a kind of high-temperature-resistant steel wire wire rope core of the utility model elevator belt is: on the production line of steel wire rope core forming cart, be equipped with thermal insulation layer 1 from top to bottom on Steel cord, upper anti-tear layer 2, core glue-line 3, lower anti-tear layer 5, then lower thermal insulation layer 6 forms made-up belt with them through pressing, and then sulfuration becomes finished product on vulcanizing press.
the utility model high-temperature-resistant steel wire wire rope core elevator belt, on it, thermal insulation layer and lower thermal insulation layer adopt and are mixed with asbestos fiber, the ethylene propylene diene rubber of aramid fiber short fibre and adhesives is made, and thermal insulation layer is laid on the skin of anti-tear layer and lower anti-tear layer, the aging breach that can not only effectively stop anti-tear layer and lower anti-tear layer, the aging disengaging of protective core glue-line and Steel cord, but also reduced coefficient of thermal conductivity, can stop the heat of outside material to the elevator belt internal delivery by actv., played good thermal insulation effect, the resistance to elevated temperatures of the elevator belt that improves, and increased the brute force of elevator belt, reduced the damage rate of load-transfer device, saved cost, the work efficiency that improves simultaneously.
Above-mentioned explanation has fully disclosed the specific embodiment of the present utility model.It is pointed out that being familiar with any change that the person skilled in art does the specific embodiment of the present utility model does not all break away from the scope of claims of the present utility model.Correspondingly, the scope of claim of the present utility model also is not limited only to previous embodiment.
