Problems solved by technology

Because in the crawling process, the ladder is subject to force, it is prone to shaking, so that the escape personnel are easy to fall from the ladder when the ladder shakes, causing secondary injuries, and the existing ladder is usually made of fire ropes. In the event of a fire, It will be broken by fire and cause damage, which makes the use of safety hazards

Embodiment 1

[0026] Such as figure 1 As shown, a kind of high-rise building fire escape ladder comprises left ladder frame 101, right ladder frame 102 and several cross bars 103 arranged between left ladder frame 101 and right ladder frame 102, described left ladder frame 101 and The right ladder frame 102 is made by winding stainless steel wires, a high temperature resistant layer is provided on the surface of the left ladder frame 101 and the right ladder frame 102, and a fixing device is provided in the middle of the cross bar 103 , the fixing device includes a fixed end 104 detachably connected to the cross bar 103, a connecting end 105 is arranged on the fixed end 104, and the connecting end 105 and the fixed end 104 A hollow ring structure is formed, one end of the connecting end 105 is hinged on the fixed end 104, a groove 106 is arranged in the middle of the other end, and a stud 107 is arranged in the groove 106, A rotating rod body 108 is provided on the polished rod cylinder in...

Embodiment 2

[0030] In this embodiment, on the basis of Embodiment 1, in order to facilitate the installation of double-ended studs, in this embodiment, preferably, through holes are respectively provided on the opposite side end faces of the groove 106, and the double-ended studs The outer diameter of the head stud 107 is smaller than the inner diameter of the through hole, and the two ends of the double-ended stud 107 pass through the through hole respectively, and the two ends of the double-ended stud 107 are respectively provided with locking Nut 111. By adopting the through-hole structure, it is possible to facilitate the installation of the double-ended studs, and at the same time, the relative rotation of the double-ended studs is facilitated to facilitate the relative rotation of the rotating rod body.

[0031] In order to facilitate the installation of the rotating rod body, in this embodiment, preferably, a threaded hole is provided on the polished rod cylinder surface of the dou...

Abstract

The invention discloses a fire-fighting escape rope ladder for a high-rise building. The fire-fighting escape rope ladder comprises a left ladder frame, a right ladder frame and a plurality of transverse rods, wherein the transverse rods are arranged between the left ladder frame and the right ladder frame; each of the left ladder frame and the right ladder frame is manufactured by winding a stainless steel wire; a high-temperature-resistant layer is arranged on the surface of each of the left ladder frame and the right ladder frame; the middle part of each transverse rod is provided with a fixing device; each fixing device comprises a fixing end detachably connected onto the corresponding transverse rod; a connecting end is arranged on each fixing end; each connecting end and the corresponding fixing end form a hollow annular structure; one end of each connecting end is hinged to the corresponding fixing end; the middle part of the other end of each connecting rod is provided with a groove; a double-end stud is arranged in each groove; and a rotating rod body is arranged on a polished rod stud surface arranged at the middle part of each double-end stud. The fire-fighting escape rope ladder has the advantages that the rope ladder is fixed outside the building by the fixing devices, so that the rope ladder is relatively stable; and the potential safety hazard due to swinging in the use process of the rope ladder is avoided.

Description

technical field [0001] The invention relates to a fire-fighting escape ladder for a high-rise building. Background technique [0002] When situations such as fires occur in high-rise buildings, firefighters often use soft ladders to help trapped people escape. Because in the crawling process, the soft ladder is subject to force, it is easy to shake, so that the escape personnel are easy to fall from the soft ladder when the soft ladder shakes, causing secondary injury, and the existing soft ladder is usually made of a fire rope. In the event of a fire, It will be broken by fire and cause damage, making it a safety hazard in use. Contents of the invention [0003] The purpose of the present invention is to provide a fire-fighting escape ladder for high-rise buildings, which can improve the problems existing in the prior art. By using a fixing device, the ladder is fixed outside the building, making it relatively more stable, and avoiding the safety of the ladder from shaki...
