Crawler belt type dredging robot

InactiveCN108166606ASolve the current situation of difficult dredgingPowerfulSewer systemsHydraulic cylinderSynchronous motor
The invention discloses a crawler belt type dredging robot, and belongs to the technical field of environmental protection equipment. The crawler belt type dredging robot includes a dredging reamer device, a turnover mechanism, a double-arm pushing mechanism, a dredging robot body and a hydraulic system. An overturning hydraulic cylinder drives a bucket to turn over downward, the turn-over angle of the overturning hydraulic cylinder is set to be 35 degrees, and it is ensured that after dredging, residual sludge of the bucket can smoothly fall down. Big connection beams are connected with a left walking crawler belt and a right walking crawler belt respectively, at the same time, a base is provided for four supporting square steels, the speed of a walking motor is controlled by controllingthe displacement of a valve element of a load-sensitive proportional multi-way valve, a synchronous motor ensures synchronous advancing of the crawler belts, two-way electromagnetic throttles ensure left turning and right turning of the walking motor, and thus the walking crawler belts can stably walk. The robot is simple and reliable in structure, at the same time, sludge is conveyed efficiently,the dredging efficiency is largely improved, the robot can be suitable for dredging tasks of drainage pipelines large in pipe diameter and box culverts, and the problem that at present, the dredgingprocesses of existing drainage pipelines large in pipe diameter and existing box culverts are difficult is solved.
