Fire-reconnoitering and fire-extinguishing robot and operation method thereof

Abstract

The invention discloses a fire-reconnoitering and fire-extinguishing robot. The fire-reconnoitering and fire-extinguishing robot comprises a caterpillar chassis, a fire-extinguishing water cannon anda reconnoitering mechanism, wherein the fire-extinguishing water cannon and the reconnoitering mechanism are arranged on the caterpillar chassis; the caterpillar chassis is composed of a chassis body,a chassis shell, a suspension cross beam, driving wheels, a driven wheel set, support belt wheel sets, bearing wheel sets, damping plate sets, elastic components, an approach wheel set, tensioning mechanisms, an obstacle avoidance assembly, a warning assembly, a driving assembly, a controller, a wireless transmission assembly, caterpillar assemblies, a dustproof cover plate, searchlights and a lithium battery. Through the fire-reconnoitering and fire-extinguishing robot, the problem of slippage and removal between the driving wheels and the caterpillar is solved; the efficient transmission between the driving wheels and the caterpillar is achieved; the adhesion performance between a suspension system with the caterpillar in the obstacle surmounting process is ensured; the stability of therobot when surmounting the obstacles and climbing can be also improved; the function of tensioning the suspension system on the robot is achieved; the safety and the stability of movement of the robot are further improved; the maintenance difficulty and the usage cost of the robot are reduced.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a fire-fighting reconnaissance and fire-extinguishing robot and a working method thereof. Background technique [0002] Firefighters have many disadvantages in the rescue or investigation of accident sites such as high-risk fires, and the application of fire detection and fire fighting robots was born. The fire reconnaissance and fire extinguishing robot can replace the firefighters to realize the fire extinguishing function in the periphery. At the same time, removing the hose can replace the firefighters to enter the dangerous disaster accident scene to realize the reconnaissance and even rescue functions, so the development prospect is broad. [0003] However, on the one hand, the on-site environment in fire and other scenes is extremely harsh, especially there are many obstacles on the ground or in space, which poses a huge challenge to the robot's obstacle-surmoun...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a fire-fighting reconnaissance and fire-fighting robot. Aiming at the driving efficiency and stability of the current driving wheel and crawler belt, the high-efficiency transmission function between the driving wheel and the crawler belt is realized through the gear-shaping driving wheel and the matching crawler belt; Insufficient climbing and obstacle performance of the system, by designing a double-row and double-row composite approach wheel to ensure the fit performance of the suspension system and the track during the obstacle-crossing process, the robot’s obstacle-climbing and climbing ability is significantly improved; for the tension of the robot suspension system The disadvantages of the mechanism, through the wedge-shaped tensioning mechanism, the tensioning function of the upper suspension system of the robot is realized to ensure the tightness of the robot's track movement, thereby further improving the safety and stability of the robot's movement and reducing the difficulty of robot maintenance
