Caterpillar-type driving system of patrolling robot

Abstract

The invention relates to a caterpillar-type driving system of a patrolling robot. The caterpillar-type driving system comprises a driving wheel assembly, a driving wheel shaft fixed piece, a side frame, a caterpillar plate, drag chain wheels, thrust wheels, end covers, thrust wheel fixed pieces, a guide wheel, a caterpillar pin, a tensioning nut, a movable piece, a tensioning bolt, a tensioning fixed piece, drag chain wheel fixed pieces, a guide wheel supporting piece and a control part, wherein the driving wheel shaft fixed piece is fixedly arranged on the side frame by a bolt; a shaft of the driving wheel assembly is fixedly mounted at the front end of the side frame by the driving wheel shaft fixed piece; the driving wheel assembly is engaged with grooves at the two sides of a caterpillar chain; the two drag chain wheels are fixedly arranged on the side frame by the drag chain wheel fixed pieces; the four thrust wheels are fixedly arranged on the side frame by the thrust wheel fixed pieces; the guide wheel is connected with the movable piece by the guide wheel supporting piece; and the two end covers are respectively and fixedly arranged on each of the outer sides of the thrust wheels and the guide wheel. The invention designs an effective caterpillar driving system by utilizing a wheel hub motor; and the caterpillar-type driving system is simple in structure and convenient to operate and the speed control is more accurate.

Description

technical field [0001] The invention relates to a patrol robot crawler driving system, which is used for driving a patrol crawler mobile robot. Background technique [0002] Accidents caused by earthquakes and other disasters in recent years have become more and more frequent, and how to conduct effective on-site detection and rescue in the shortest time after the accident has become a topic that more and more scholars have begun to pay attention to. From the big explosion accident of the Chernobyl nuclear power plant in the former Soviet Union to the 5.12 in Wenchuan, and then to the Fukushima earthquake and nuclear power plant accidents, people are increasingly using robots to detect dangerous accident sites and take rescue measures. The patrol robot can replace people and animals to enter the dangerous scene to detect the scene situation, and send the scene information to the operators outside the scene to help the staff to carry out rapid and effective rescue measures. ...

AI Technical Summary

Problems solved by technology

However, the crawler patrol robots in the past were basically driven by fuel engines or traditional motors. Due to the problems of gearboxes, differentials or motor reducers, the structure of the crawler drive system is complicated, and the speed control is more complicated.
