Module combined type rope protector

Abstract

The invention provides a module combined type rope protector. The module combined type rope protector comprises a first module, a second module, a third module, a fourth module, a fifth module and a sixth module, wherein all the modules are movably connected in sequence. The first module comprises a U-shaped groove pulley, a rotary platform and bases. The U-shaped groove pulley is fixed to the rotary platform, an angular contact ball bearing is arranged in the rotary platform, a boss is sleeved with the angular contact ball bearing, and the first module and the second module, the third moduleand the fourth module, the fifth module and the sixth module, the second module and the third module, and the fourth module and the fifth module are connected at the positions of the bases correspondingly. The module combined type rope protector has the beneficial effects that the multiple same modules are movably connected at different positions of the bases through all hinges, all the modules can be flexibly combined and transformed according to terrains and actual use requirements, and therefore the module combined type rope protector can be suitable for the multiple terrains and the situation that multiple ropes are simultaneously used.

Description

technical field [0001] The invention relates to the technical field of fire fighting and rescue equipment, in particular to a modular combined rope protector. Background technique [0002] In high-altitude operations, rope rescue, caving, fire-fighting and other activities, it is often necessary to use ropes for suspension, dragging up and rope down operations at sharp or rough corners such as wall corners, rocks, eaves, window sills, etc. During the sliding process of the rope, on the one hand, the high temperature generated by the sliding friction will cause the rope to be heated and blackened or even deformed; on the other hand, the rough contact surface will damage the rope skin. There is a risk of a rupture, with a more serious chain reaction. Rope is the most important tool to connect life, and to love rope is to love life, so it is particularly important to develop equipment for protecting rope. [0003] There are currently three types of rope protectors on the mark...

AI Technical Summary

Problems solved by technology

The first two types of protectors use the surface of the protector to isolate rough and sharp objects, but these two types of protectors have the disadvantages of insufficient strength and a large sliding friction coefficient on the contact surface; the metal rope protection wheel uses the rotation of the pulley to realize the rolling friction of the rope. , but when the protector bears two or more ropes moving in opposite directions at the same time, the pulley will lose its rotation function, resulting in rolling friction changing to sliding friction, so its dragging efficiency is still not high
