Problems solved by technology

The steel wire rope is made of metal material, which is of high quality, but it is still not light enough for installation and transportation
[0008] Synthetic fiber rope is easy to soften and deform under high temperature environment, thus affecting the locking function of the end, resulting in failure, causing the rope body to fall off and causing safety accidents

Embodiment 1

[0029] A high-temperature protection structure for a terminal, comprising a heat-shrinkable sleeve that can be installed on the terminal, and modified glass fiber coated on the outer surface of the heat-shrinkable sleeve. The end is a wedge-shaped metal socket end, and the heat-shrinkable sleeve is composed of trans-1,4-polyisoprene, which is made into a heat-shrinkable sleeve through irradiation and cross-linking. Put it in the wedge-shaped metal socket device at the end, heat it with an open flame, and the sleeve shrinks and forms and fits closely to the wedge-shaped metal socket at the end. Then, the modified glass fiber with flame-retardant and heat-insulating properties is wound or bonded on the outer surface of the heat-shrinkable sleeve.

[0030] The modified glass fiber is: the mass ratio is 30%Na 2 SiO 3 , 35% B 2 o 3 , 10% Sb 2 o 3 , 10%TiO 2 , 5% Al 2 o 3 , 5% MgO, 5% Fe 2 o 3 The nano-inorganic substances are added to the glass fiber, and then fused at 3...

Abstract

The invention relates to an end high temperature protection structure and a traction rope end structure. The end high temperature protection structure includes a heat shrinkable sleeve that can be installed on the end, and a modified heat-resistant heat-insulating sleeve coated on the heat shrinkable sleeve. It is characterized in that: the heat shrinkable sleeve is made of heat shrinkable shape memory material. The traction rope end structure includes. The end for fixing the rope body, the heat shrinkable sleeve arranged on the surface of the end, and the modified glass fiber coated on the surface of the heat shrinkable sleeve, are characterized in that: the heat shrinkable sleeve is made of shape memory material. The present invention is beneficial in that under extreme high temperature conditions, the end temperature is prevented from being too high to affect the locking function, so that the rope body of the elevator rope end does not melt, deform, loosen or slip when heated, thereby completely avoiding accidents.

Description

technical field [0001] The invention relates to a structure of the end of a traction rope, in particular to a high temperature protection structure of the end and a structure of the end of the traction rope which can prevent high temperature softening. Background technique [0002] Elevator traction rope is an important part of the elevator system, and the mainstream of the existing elevator traction rope is steel wire rope. [0003] PBO fiber, aramid fiber, etc. have excellent properties such as ultra-high strength, high modulus, temperature resistance, acid and alkali resistance, light weight, and good dimensional stability, so they are ideal materials for making high-strength ropes. The strength of the synthetic fiber rope made by twisting the above fibers in a certain proportion is 3 to 5 times that of steel wire, and its weight is only about 1 / 4 of that of steel wire. It will not decompose or melt under high temperature conditions. [0004] Therefore, the synthetic fib...
