ladder

Abstract

The invention relates to the field of fire fighting lifesaving and in particular relates to a rope ladder. The rope ladder comprises a first guide rope, a second guide rope, a third guide rope, first pedaling parts and second pedaling parts, wherein the first guide rope, the second guide rope and the third guide rope are sequentially arranged in parallel; the first pedaling parts are arranged between the first guide rope and the second guide rope, and are vertical to the first guide rope and the second guide rope; the second pedaling parts are arranged between the second guide rope and the third guide rope, and are vertical to the second guide rope and the third guide rope; the second pedaling parts are arranged between the extension lines to the third guide rope of the adjacent first pedaling parts. The rope ladder comprises the three guide ropes. When people climb with the rope ladder, the second guide rope is held, the gravity centers of the hands, feet and body is in a same vertical plane, and the rope ladder is prevented from twisting in the left and right directions during climbing, so that the body balance is easily controlled. Therefore, a transverse pedal is not required to stabilize the rope ladder, and the rope ladder is convenient to carry.

Description

technical field [0001] The invention relates to the field of fire fighting and lifesaving, in particular to a soft ladder. Background technique [0002] Ladder is a climbing tool that people use in order to go back and forth between two places with a certain height difference. [0003] The soft ladder in the related art, such as figure 1 As shown, it is composed of two soft ropes 109 and a pedal 110, and the pedal 110 is arranged between the two soft ropes 109 and is perpendicular to the soft rope 109. When people are climbing, because the soft rope is unstable, the soft ladder will shake, and it is easy for people to step on the air, thereby causing danger. In order to solve the above-mentioned problems, people will be provided with horizontal palm pedals 111 every several pedals 110, and the horizontal palm pedals 111 are respectively arranged on two soft ropes 109 and are perpendicular to the soft ropes 109. The length of the horizontal palm pedal 111 will be more than...

AI Technical Summary

Problems solved by technology

[0004] But this structure in the related art does not prevent the soft ladder from shaking. When people climb the soft ladder in the related art, they still shake from side to side, so it is difficult for people to balance their bodies, thus causing dangers such as stepping on the air.

And, the length of horizontal palm pedal 111 is very long, and it is also inconvenient to carry
