Abstract

The invention provides a full steering chassis, and belongs to the technical field of an intelligent patrolling vehicle design and manufacturing. The full steering chassis comprises a wheel with a hubmotor and a brake disk; the chassis is a square framework structure, and four cross beams are aligned in the middle part in a non-uniform manner; a lead rail base is arranged between the end beams atboth heads and the adjacent cross beams, both ends of longitudinal lead rails are fixed with the cross beams through the lead rail base; a lead screw is arranged between two longitudinal lead rails,and two end output shafts arranged on first stepping motors with double output shafts on two cross beams in the middle are connected with the lead screw through a coupling; the lead screw is fixed with the cross beams with the lead rail base and the middle part of the end beam through a vertical base angle contact ball bearing; bottom parts at both ends of a rack sleeve are provided with slide blocks matched with the longitudinal lead rails, and the middle part is provided with a nut slide block spirally matched with the lead screw; the gear is fixed with the output shaft of a second steppingmotor and meshed with a rack at the opening on the rack sleeve; a second stepping motor is fixed with the bottom part of the middle part of the chassis end beam.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of intelligent inspection vehicles. Background technique [0002] Under normal circumstances, the fixed monitoring equipment in the underground comprehensive utility gallery cannot meet the actual operation needs of the underground comprehensive utility gallery in a modern smart city due to problems such as poor mobility, low intelligence, high maintenance costs and complicated processes. For the method of manual downhole inspection, due to the long-term underground closed environment, the air is not circulated, the lighting is poor, and the space is oppressed, causing a large amount of toxic and harmful gases to gather, causing harm to the lives and physical and mental health of the staff. At present, intelligent inspection vehicles that have not been used on a large scale, because of their inflexible steering, the friction between the wheels and the ground during the steering proc...
