Scaling ladder structure for fire fighting

Abstract

The invention discloses a scaling ladder structure for fire fighting, and belongs to the technical field of fire fighting equipment. The scaling ladder structure is composed of a first-stage scaling ladder, a second-stage scaling ladder, a third-stage scaling ladder, a sliding groove, a sliding rod, motors and gears; and the first-stage scaling ladder is connected with a scaling ladder platform through a rotating shaft, the sliding groove is formed in the bottom of the first-stage scaling ladder, a sliding block is arranged in the sliding groove, the top end of the sliding rod is connected with the sliding block, the bottom end of the sliding rod is connected with the scaling ladder platform in a hinged mode, the second-stage scaling ladder is arranged inside the first-stage scaling ladder, the gears, transmission shafts and the motors are arranged between each scaling ladder and the corresponding next-stage scaling ladder, racks are fixedly arranged on the scaling ladders, and the second-stage scaling ladder is in telescopic movement with the first-stage scaling ladder through the gear rack transmission. According to the scaling ladder structure, the structure is novel, the working principle is clear, the angle, relative to the scaling ladder platform, of the first-stage scaling ladder is adjusted through the sliding groove in the bottom of the first-stage scaling ladder, thesliding block and the sliding rod, and relative movement between each stage of the scaling ladders and the corresponding next stage of the scaling ladders is formed through the gears, the motors, thetransmission shafts and the racks inside the scaling ladders, so that the fire-fighting operation efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and relates to a ladder structure for fire-fighting. Background technique [0002] The aerial ladder fire truck is equipped with a hydraulically raised platform for firefighters to climb up and fight fires in high-rise buildings, tall facilities, oil tanks, etc., rescue trapped people, rescue valuable materials and complete other rescue tasks. The vehicle is equipped with a telescopic aerial ladder, which can be equipped with a lifting bucket turntable and a fire extinguishing device, which can be used by firefighters to climb up to put out fires and rescue trapped people. It is suitable for fighting fires in high-rise buildings. [0003] However, most of the existing aerial ladder fire trucks use hydraulic structures. The larger the aerial ladder height, the greater the power required by the hydraulic pump, and the hydraulic system often has defects such as oil leakage, which bri...

AI Technical Summary

Problems solved by technology

[0004] The present invention is aimed at the hydraulic structure of the traditional aerial ladder fire truck. The larger the aerial ladder height, the greater the power required by the hydraulic pump, and the hydraulic system often has defects such as oil leakage, which brings great inconvenience to the use and affects the efficiency of fire-fighting operations. In view of the deficiencies, a fire-fighting aerial ladder structure is proposed. By changing the driving structure of the aerial ladder, the deficiencies in the existing technology are solved, and the efficiency of fire-fighting operations is further improved.
