AI Technical Summary
The existing rope protectors have problems such as insufficient strength, large sliding friction coefficient on the contact surface, and low drag efficiency in high altitude operations and rope rescue. Especially when multiple ropes are used at the same time, the protector loses its rotation function, causing the rolling friction to become sliding friction.
The module combination rope protector is adopted to connect multiple identical modules through hinge hinges to achieve flexible combination and rotation of modules. The sliding friction of the rope is converted into rolling friction by using a U-shaped groove pulley to reduce friction.
It achieves efficient protection under multiple terrain and multiple ropes, reduces the friction resistance of ropes, improves work efficiency, and is suitable for situations with different rope numbers.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fire rescue equipment, and in particular to a modular combined rope protector. Background Art
[0002] In aerial work, rope rescue, caving, firefighting and other activities, it is often necessary to use ropes to suspend, drag and lower on sharp or rough corners such as corners, rocks, eaves, and window sills. During the sliding of the rope, on the one hand, the high temperature generated by the sliding friction will cause the rope to turn black or even deform; on the other hand, the rough contact surface will damage the rope skin. When the tight rope is cut by a sharp object, it is very likely to break, leading to a more serious chain reaction. Ropes are the most important tool to connect life. Caring for ropes is caring for life, so it is particularly important to develop equipment to protect ropes.
[0003] There are three types of rope protectors on the market: fiber rope sheaths and pads, plastic rope protection plates, and metal rope protection wheels. 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 large contact surface sliding friction coefficient; the metal rope protection wheel uses the rotation of the pulley to achieve rope rolling friction, but when the protector is subjected to two or more ropes moving in opposite directions at the same time, the pulley will lose its rotation function, causing the rolling friction to become sliding friction, so its dragging efficiency is still not high. Summary of the invention

DETAILED DESCRIPTION
[0023] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0024] Please refer to Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a modular combined rope protector, comprising a first module 100, a second module 200, a third module 300, a fourth module 400, a fifth module 500 and a sixth module 600 which are movably connected in sequence.
[0025] The first module 100 includes a U-shaped groove pulley 110, a rotating platform 120 and a base 140. The U-shaped groove pulley 110 is fixed on the rotating platform 120 through a bearing bracket 130. In this embodiment, the outer ring edge diameter of the U-shaped groove pulley 110 is enlarged and protrudes to form a U-shaped groove. Preferably, the groove depth of the U-shaped groove pulley 110 is 12 mm, which is larger than the domestic universal rescue rope with a rope diameter of 10.5 mm and 11 mm, so that the rope can be confined in the U-shaped groove to prevent it from slipping out. In actual use of the present invention, the U-shaped groove pulley 110 converts the sliding friction of the rope into rolling friction by rotation when the rope moves, thereby effectively reducing friction resistance.
[0026] The rotating platform 120 includes an upper rotating platform 121 and a lower rotating platform 123. The upper rotating platform 121 is provided with a through hole 122 inside and covers the lower rotating platform 123. A retaining ring 124 is provided in the through hole 122. The retaining ring 124 is clearance-matched with the through hole 122 and is connected to the boss 141 by screws. The lower rotating platform 123 is cylindrical and a circular ring support platform 126 is provided at its lower end.
[0027] An angular contact ball bearing 125 is provided inside the rotating platform 120. Specifically, the angular contact ball bearing 125 is limited between the upper rotating platform 121 and the lower rotating platform 123, and the retaining ring 124 and the support platform 126 respectively press against the upper surface and lower surface of the inner ring of the angular contact ball bearing 125, and the upper rotating platform 121 and the support platform 126 respectively press against the upper surface and lower surface of the outer ring of the angular contact ball bearing 125, thereby fixing the rotating platform 120 on the angular contact ball bearing 125.
[0028] The base 140 is square and has a cylindrical boss 141 on its upper surface. The rotating platform 120 is located above the base 140, and the boss 141 is sleeved on the inner ring of the angular contact ball bearing 125, so that the rotating platform 120 can rotate around the axis of the boss 141 under the action of the angular contact ball bearing 125. A plurality of hexagon socket head screws 150 are evenly arranged on the lower surface of the base 140. By loosening or tightening each of the hexagon socket head screws 150, the length of each of the hexagon socket head screws 150 can be adjusted to adapt to an uneven surface.
[0029] The second module 200, the third module 300, the fourth module 400, the fifth module 500 and the sixth module 600 have the same structure as the first module 100, and the first module 100 and the second module 200, the third module 300 and the fourth module 400, the fifth module 500 and the sixth module 600, the second module 200 and the third module 300, the fourth module 400 and the fifth module 500 are respectively connected by the first hinge 700, the second hinge 800, the first hinge 900 and the second hinge 1000. The third hinge 900, the fourth hinge 1000, and the fifth hinge 1100 are connected at each of the bases 140. In this embodiment, the first hinge 700, the second hinge 800, and the third hinge 900 are respectively located at a corner of each of the corresponding bases 140 to realize the rotation of each module in the horizontal plane; the fourth hinge 1000 and the fifth hinge 1100 are respectively located on the side of each of the corresponding bases 140 to realize the rotation of each module in the vertical plane, thereby adapting to surfaces with angles or curves such as wall corners and rocks.
[0030] In the present invention, the first module 100, the second module 200, the third module 300, the fourth module 400, the fifth module 500 and the sixth module 600 can be flexibly combined into a variety of different forms by rotating different angles in the horizontal and vertical planes, so as to adapt to the situation of different numbers of ropes in the rope system, please refer to Figure 4-Figure 9 , Figure 4-Figure 9 The following are typical combinations that can be used for 1-6 rope systems (the present invention includes but is not limited to these six combinations).
