Rung automatic leveling high-altitude rescue vehicle with rotary extending docking platform

Abstract

The invention relates to the technical field of fire rescue, in particular to a rung automatic leveling high-altitude rescue vehicle with a rotary extending docking platform. The high-altitude rescuevehicle comprises a chassis, a ladder frame, the rotary extending docking platform and a docking platform leveling mechanism, wherein the ladder frame moves in an amplitude-change mode in the verticaldirection; the ladder frame is provided with rung connecting rods and a plurality of leveled rungs which are arranged in parallel and spaced in a length direction of the ladder frame, the plurality of leveled rungs are hinged to the ladder frame, and the rung connecting rods are used for connecting adjacent leveled rungs in a hinge mode; and one end of the docking platform leveling mechanism is hinged to the front end of the ladder frame, and the other end of the docking platform leveling mechanism is hinged to the rotary extending docking platform, and the docking platform leveling mechanismis used for driving the leveled rungs to be adjusted in a horizontal state. In the embodiment, when traditional fixed stepped rungs are changed into the leveled rungs hinged to the ladder frame, whenthe ladder frame moves in an amplitude-change mode, the docking platform leveling mechanism drives the leveled rungs to be adjusted in a horizontal state, so that people can stepping more comfortableand safer, the rescue safety is improved, and the rescue efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of firefighting and rescue, in particular to a high-altitude rescue vehicle with a slewing extension docking platform and automatic leveling of ladders. Background technique [0002] In high-speed rail, light rail and other occasions, high-rise commercial city squares and other occasions, there are many people. In the event of fire or other emergencies, timely evacuation and rescue are required. Generally, people can be evacuated by using a ladder fire truck or a rescue device that lifts the fire truck. [0003] At present, the ladder frame of general ladder fire trucks and ascending platform fire trucks is in the form of climbing ladders, and the position of people's feet is square or round tubes, the contact area is small, and people's comfort and safety are not good; Low, the number of people rescued at one time is limited; the ladder pedal is a stepped ladder fixed on the ladder frame, which has a stron...

AI Technical Summary

Problems solved by technology

[0003] At present, the ladder frames of general aerial ladder fire trucks and fire trucks with climbing platforms are in the form of climbing ladders, and the foot position of people is square tube or round tube, the contact area is small, and the comfort and safety of people are not good; Low, the number of people rescued at one time is limited; the ladder pedal is a stepped ladder fixed on the ladder frame, which has a strong bearing capacity. In actual rescue, the boom needs different luffing angles, but the angle of the ladder pedal plane cannot be adjusted with the ladder. The luffing angle of the frame changes, and when the luffing angle differs greatly, the ladder pedals are obviously inclined relative to the horizontal plane, and the feeling of people's pedaling is not good, and people are already flustered and nervous. Dare not to go up the rescue ladder, or dare not move halfway up the rescue ladder, which seriously affects the efficiency of rescue
