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 an end head includes a heat shrinkable sleeve that can be installed on the end head and a 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 cross-linked by irradiation to make a heat shrinkable sleeve. The body is sheathed in the wedge-shaped metal socket device at the end, heated by an open flame, and the sleeve is contracted and shaped to tightly adhere to the wedge-shaped metal socket at the end. Then wind or bond the modified glass fiber with flame retardant and thermal insulation properties 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 material is added to the glass fiber, and then fused at 300°C to 360°C t...

Embodiment 2

[0032] A high-temperature protection structure for an end head includes a heat shrinkable sleeve that can be installed on the end head and a 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 cross-linked by irradiation to make a heat shrinkable sleeve. The body is sleeved in the wedge-shaped metal socket device at the end, heated by an open flame, and the sleeve is contracted and shaped to tightly fit the wedge-shaped metal socket at the end. Then wind or bond the modified glass fiber with flame retardant and thermal insulation properties on the outer surface of the heat shrinkable sleeve.

[0033] The difference from Example 1 is that the mass ratio is 20% SiO 2 , 35% B 2 O 3 , 10% Sb 2 O 3 , 10% TiO 2 , 10% CaO, 5% Al 2 O 3 , 5%MgO, 5%K 2 The nano inorganic substance of O is added to the glass fiber, and then fused at 300°C to ...

[0035] A high-temperature protection structure for an end head includes a heat shrinkable sleeve that can be installed on the end head and a 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 cross-linked by irradiation to make a heat shrinkable sleeve.

Abstract

The invention relates to a novel end head high-temperature protection structure and novel traction rope end head structure. The end head high-temperature protection structure comprises a heat-shrinkable sleeve which can be mounted on an end head as well as a modified glass fiber which coats the heat-shrinkable sleeve and has flame-retardant and heat-insulation performance; and the end head high-temperature protection structure is characterized in that the heat-shrinkable sleeve is made of a heat-shrinkable shape memory material. The traction rope end head structure comprises an end head for fixing a rope body, a modified glass fiber arranged on the surface of the end head and a modified glass fiber coating the surface of the heat-shrinkable sleeve; and the traction rope end head structureis characterized in that the heat-shrinkable sleeve is made of a shape memory material. The novel end head high-temperature protection structure and traction rope end head structure have the beneficial effects that the situation that a locking function is influenced due to the fact that the temperature of the end head is too high under extreme high-temperature conditions can be avoided, so that the rope body of the end head of an elevator rope does not melt, deform, loosen and slide off when being subjected to heating, and thus accidents can be completely avoided.

Description

Technical field [0001] The invention relates to a traction rope end structure, in particular to a high temperature protection structure and a traction rope end structure capable of preventing high temperature softening. Background technique [0002] The 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 synthetic fiber rope made of the above-mentioned fibers mixed and twisted in a certain proportion has a strength of 3 to 5 times that of a steel wire, and a weight of only about 1 / 4 of that of a steel wire, and does not decompose or melt under high temperature conditions. [0004] Therefore, synthetic fiber rope made of PBO ...
