Foldable type high-altitude fire-fighting rescuing device

Abstract

The invention discloses a foldable type high-altitude fire-fighting rescuing device. The foldable type high-altitude fire-fighting rescuing device comprises a foldable type hoisting frame, a foldable type hanging ladder and a top platform, wherein a base is arranged at the lower end of the foldable type hoisting frame; the top platform is fixedly arranged at the upper end of the foldable type hoisting frame; the foldable type hanging ladder is hinged with the top platform. The foldable type high-altitude fire-fighting rescuing device further comprises a lift car; the lift car is connected with the foldable type hoisting frame and the foldable type hanging ladder by rails. According to the foldable type high-altitude fire-fighting rescuing device, the higher fire-fighting rescuing height and the larger rescuing range can be realized; the fire-fighting range and the rescuing range are not limited by the working height; the fire-fighting function is stronger and the efficiency is higher; the rescuing and conveying work is rapid and efficient; the high-altitude conveying capacity is stronger; the equipment has a self-protection capability, is low in construction cost, and is easy to manufacture.

Description

technical field [0001] The invention relates to the field of high-altitude rescue machinery, in particular to a foldable high-altitude fire-fighting and rescue device. Background technique [0002] At present, known high-altitude fire-fighting and rescue equipment mainly contains the main types such as telescopic fire-fighting aerial ladder vehicle and the high-altitude fire-fighting rescue vehicle of the telescopic boom end hinged telescopic crank arm structure. [0003] The telescopic fire-fighting aerial ladder vehicle has relatively small effective height and operating range after each section of the aerial ladder is fully extended, and can be used for fire-fighting and rescue of ordinary buildings, but is not suitable for fire-fighting and rescue of modern high-rise buildings. [0004] The high-altitude fire rescue vehicle with the end of the telescopic main arm hinged with the telescopic crank structure has a relatively large lifting height. It is currently the mainstr...

AI Technical Summary

Problems solved by technology

[0005] Fire fighting and rescue operations in high-rise buildings are mainly carried out at the height of the fire floor and above. Due to the constraints of many factors such as building structure, fire situation, site, road, and wind direction, it is difficult for high-altitude fire-fighting and rescue vehicles to The most suitable distance and position work

Limited by the support mode and support range of the vehicle chassis, the greater the height of the equipment's upward extension, the higher the center of gravity, and the greater the overturning moment formed by the extension of the operating arm, resulting in the smaller effective range of high-altitude operations, even if the equipment can meet the rescue requirements. height, it is often impossible to send the rescue platform at the end of the working arm to the desired position

[0006] In addition to the small range of high-altitude rescue operations, the currently known high-altitude fire rescue vehicles also have the problems of low rescue efficiency and low fire extinguishing efficiency:

In the process of personnel rescue and transportation, because the working platform where the fire monitor is located has deviated from its proper height and position, it is impossible to carry out effective fire extinguishing operations at the same time as personnel transportation, and its slow lifting process takes a lot of time. The actual consequences are often irreversible fire spread and loss of control, leading to increased casualties and property losses

[0009] The problems existing in the above-mentioned currently known high-altitude fire-fighting and rescue equipment have been verified in a large number of on-site operations, but the structure itself cannot overcome these defects
