Technical Field

The invention relates to the technical field of fire fighting equipment, in particular to multifunctional fire fighting equipment with a rotary arm support and a using method thereof.

Background

Modern fire trucks are usually equipped with steel ladders, water guns, portable fire extinguishers, self-contained respirators, protective clothing, breaking and dismantling tools, first-aid tools and the like, and some fire extinguishing devices can also carry large fire extinguishing equipment such as water tanks, water pumps, foam fire extinguishing devices and the like. The appearance of the fire fighting truck in most areas is red, and the appearance of part of special fire fighting trucks is also the same, and the top of the fire fighting truck is usually provided with a warning bell, a warning lamp and an explosion lamp. Common fire fighting vehicle types include water tank fire fighting vehicles, foam fire fighting vehicles, aerial ladder fire fighting vehicles, and the like.

At present, a single fire truck has a single application function, for example, a main equipment tool for fire extinguishing is mainly arranged on a fire truck, but equipment for realizing hoisting and traction functions is not arranged, and a plurality of fire trucks with different functions need to work at one time to complete rescue operation on site in some complex rescue sites, so that traffic jam is caused, mobility is not flexible, and the best time for accident rescue can be delayed.

In order to rescue that can be faster, aerial ladder fire engine has been designed, aerial ladder fire engine fire control is as a very important rescue equipment, at home and abroad wide use, and at present, aerial ladder fire engine's main operation mode is: the aerial ladder frame can reach the operation height through lifting and stretching, so that firefighters and fire-fighting tools can be conveyed to the high altitude, or trapped personnel can be rescued from the high altitude, and the trapped personnel can climb up and down the aerial ladder frame only through the working bucket or the related personnel. The aerial ladder vehicles with the height of 42 meters or more are basically provided with pulleys, the aerial ladder frames are used as guide rails, the aerial ladder vehicles slide up and down under the traction of steel wire ropes, and the lifting buckets can quickly slide along the aerial ladder vehicles, so that workers or rescued persons can be quickly transported at high altitude and on the ground. However, the aerial ladder vehicles with the height of 32 meters or less are rarely provided with pulleys, so that rescue workers generally enter the working bucket from a ladder or a fixed pedal in the middle of the vehicle when rescue is carried out, the working bucket falls to the ground after rescue, the rescued workers are conveyed to the ground, and if the rescued workers are more, the rescued workers need to climb the root of the ladder frame to the rotary table and reach the ground after passing through the walking table plate.

Earlier, be equipped with the ladder frame on the roof, set up the ladder on the ladder frame, when taking, pull down the ladder frame from the afterbody of vehicle earlier, pull down the ladder frame from the roof again and take off and pull down the ladder promptly the fire ladder, this kind of structural configuration can be revealed by utility model patent grant publication No. CN2580997Y, can specifically see utility model patent grant publication No. CN2839538Y (the side that the fire engine used stretches out upset ladder frame).

CN2839538Y eliminates the disadvantages of CN2580997Y, however, the technical solution provided by CN2839538Y still requires the firefighters to climb the top of the fire fighting truck, draw the ladder rack, move the ladder rack with the ladder carried thereon to a position substantially to the side of the fire fighting truck, and then press the handle connected to the ladder rack, so that the ladder rack with the ladder is tilted downward, so that the firefighters can pull out and take away the ladder rack from the fire fighting truck for the fire scene after unlocking the lock for locking the ladder;

the fire engine disclosed by CN2839538Y has the following defects that the turning ladder frame with one side extending out is used for the fire engine: firstly, the action of moving the ladder pulling frame to the side position of the vehicle is manually finished by the fire fighters, and the fire fighters climb to the roof at first, so that the action is slow, and the working strength of the fire fighters is high; secondly, the action that the ladder pulling frame carries the ladder to incline downwards is also finished by the manual work of the fire fighter, so the working strength of the fire fighter is further improved.

However, the above patents still have the following problems:

(1) the root part of the ladder frame is usually arranged at the tail part of the walking board of the fire engine, so that rescued people climb the transition part of the rotary table and the ladder frame with great effort and easily fall off from the tail part of the walking board, the safety and comfort of the people can not be ensured, the rescue speed can be influenced, and the rescue efficiency can be reduced;

(2) the application function of a single fire truck is single, for example, a main equipment tool for fire extinguishing is mainly arranged on the fire truck, but equipment for realizing hoisting and traction functions is not arranged, and in some complex rescue sites, a plurality of fire trucks with different functions need to work at one time to complete rescue operation on site, so that traffic jam is caused, mobility is not flexible, and the best time for accident rescue can be delayed;

(3) the action that the existing pulling ladder frame carries the pulling ladder to incline downwards is also finished by manual work of fire fighters, so that the working strength of the fire fighters is further increased, and the movement and the downward inclination of the pulling ladder frame are both manually operated rather than mechanically operated, so that the working difficulty of the fire fighters cannot be reduced.
