Posture-variable mobile robot

Abstract

The invention relates to a posture-variable mobile robot. The posture-variable mobile robot comprises a track (1), a driving roller (3), a movable driven roller (7), a fixed driven roller (9), a track supporting mechanism (4), a rotation driving arm swinging mechanism (6) and a tensioning mechanism (11). The posture-variable mobile robot is characterized in that the track (1) is installed on the driving roller (3), the movable driven roller (7) and the fixed driven roller (9); a rolling bearing is installed inside one end of the rotation driving arm swinging mechanism (6), the inside rolling bearing is connected with an output shaft of the movable driven roller (7), and drives the movable driven roller (7) to rotate. The posture-variable mobile robot is capable of passing in a long and narrow passage through changing gesture and passing through obstacles, and can be mounted in a small lifting container for mines, so that carrying, lifting, releasing and recovering of the robot can be controlled remotely by a ground industrial-control terminal.

Description

technical field [0001] The patent of the present invention belongs to the field of robots, specifically a mobile robot with variable attitude. Background technique [0002] Once mine disasters such as flooding of shafts, stope roof fall, gas explosions, coal dust explosions, etc. occur underground in coal mines, the miners on site are often trapped in a local space underground and lose contact with the outside world, and the most urgent need for emergency rescue work in mine disasters is to obtain the accident scene in time Condition. [0003] Mine search and rescue crawler robots require a certain walking speed and good ability to overcome obstacles, such as ZL: 200820083326.4 coal mine search and rescue robot with closed crawler characteristics, this equipment mainly includes a pair of walking crawlers and a pair of swing arm crawlers, swing arm crawler Rotate around the front axle to overcome obstacles. The main purpose of this robot is to prevent foreign matter from en...

AI Technical Summary

Problems solved by technology

This robot is mainly to prevent foreign matter from entering the crawler and improve the adaptability to complex environments. However, its large size makes it unsuitable to enter the lift bin for mine disaster rescue.

For example, ZL: 201010514583.1 small variable crawler search and rescue robot. This invention mainly includes a walking mechanism and a linear push rod telescopic mechanism. The telescopic mechanism is used to overcome obstacles. This robot is small in size, but it is not an explosion-proof device and cannot be used in coal mines.
