High-altitude rescue fire fighting truck

Abstract

The high-altitude rescue fire fighting truck comprises a rescue platform, a lifting life-saving system and a ladder assembly, and the lifting life-saving system comprises a lifting sliding hopper, a first conveying chain, a first driving chain wheel, a second conveying chain, a second driving chain wheel and a driven chain wheel which are connected with the ladder assembly in a sliding mode. The two ends of the lifting sliding bucket are connected with the conveying chains respectively, when the lifting sliding bucket slides up and down, movement of the lifting sliding bucket can be well stabilized, left-right shaking is avoided, meanwhile, compared with connection of a pulley and a rope, connection of the chain wheels and the chains is more stable and not prone to slipping, and therefore sliding stability can be improved, and rescue safety can be improved. The stable up-down lifting is achieved only through one fixed pulley, two driving wheels and two chains, and compared with an existing traction structure with four fixed pulleys, one driving wheel and one rope, the traction structure is simpler, more stable and easy to install.

Description

Technical Field

[0001] The utility model relates to the technical field of fire trucks, in particular to a high-altitude rescue fire truck. Background Art

[0002] At present, the rescue of personnel in high-rise buildings is mainly carried out by ladder trucks, which can reach up to more than 70 meters. However, due to the low efficiency, it is very difficult for the rescued personnel to descend from the ladder to the ground. People who are afraid of heights, the elderly, the weak or the injured cannot descend, and the ladder truck is needed to retract the ladder, which is slow and the rescue efficiency is very low. The existing patent CN 203620134U discloses a high-altitude rescue fire truck, which has a lifeboat that can be raised and lowered for escape installed in parallel on a traditional load-bearing telescopic arm. However, the lifeboat uses ropes and four fixed pulleys to cooperate with traction to achieve sliding, and the structure is relatively complicated. Since one end of the lifeboat is suspended by a rope, it is easy to shake during the descent, so its stability is also problematic. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a high-altitude rescue fire truck, which can improve the heat dissipation efficiency without increasing the water inlet pressure of the coolant and the gap between the inner and outer pipes.

[0004] In order to solve the above technical problems, the utility model discloses a high-altitude rescue fire truck, comprising a rescue platform for temporarily receiving trapped persons at a height, a lifting and rescuing system for transferring trapped persons in the rescue platform, a ladder frame for lifting the rescue platform and serving as a guide rail for the lifting and rescuing system to lift up and down; the lifting and rescuing system comprises a lifting bucket slidably connected to the ladder frame, a first transmission chain, a first driving sprocket, a second transmission chain, a second driving sprocket, and a driven sprocket;

[0005] The first driving sprocket and the second driving sprocket are arranged at the bottom of the ladder frame, and the first driving sprocket is located above the second driving sprocket;

[0006] One end of the first conveying chain is drivingly connected to the first driving sprocket, and the other end of the first conveying chain is fixedly connected to the first end of the lifting slide;

[0007] One end of the second conveying chain is drivingly connected to the second driving sprocket, and the other end of the second conveying chain is fixedly connected to the second end of the lifting slide via the driven sprocket; the first end of the lifting slide is farther away from the driven sprocket than the second end of the lifting slide; the rotating shaft of the driven sprocket is fixed on the top of the ladder frame.

[0008] As an optional embodiment, the ladder frame is a telescopic arm, which is lifted or lowered by connecting with a hydraulic rod arranged below it.

[0009] As another optional embodiment, it also includes a vehicle-mounted gun system for extinguishing fires, reducing temperatures, and removing smoke.

[0010] As another optional embodiment, two ends of the bottom of the lifting slide are respectively provided with C-shaped structures that embrace the outer wall surface of the ladder frame to enable the lifting slide to be slidably connected to the ladder frame.

[0011] As another optional implementation, the first end and the second end of the lifting slide are both arranged on the C-shaped structure.

[0012] As another optional embodiment, the rescue platform is provided with lighting fixtures, water cannons and a rescue tool box, and the rescue tool box contains gloves, a safety helmet, a respirator, a fireproof suit and an oxygen cylinder.

[0013] As another optional implementation, the lifting slide is made of fireproof and heat-insulating material.

[0014] As another optional embodiment, a respirator and an oxygen cylinder are arranged in the lifting bucket.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0016] This embodiment connects transmission chains to the two ends of the lifting slide respectively, so that the movement of the lifting slide can be better stabilized when the lifting slide slides up and down to avoid left and right shaking. At the same time, the connection between the sprocket and the chain is more stable and less likely to slip than the connection between the pulley and the rope, thereby improving the stability of sliding and contributing to improving the safety of rescue. Relatively stable up and down lifting can be achieved by only one fixed pulley, two driving wheels and two chains. Compared with the existing traction structure of four fixed pulleys, one driving wheel and one rope, it is simpler, more stable and easier to install. BRIEF DESCRIPTION OF THE DRAWINGS
