Abstract
A vehicle for external inspection of tubing conformed by a body with a magnetic traction arrangement in its lower part and at least one inspection device mounted on the body; In which the magnetic drive arrangement includes two front magnetic wheels, a rear magnetic wheel coupled to two servomotors, one for controlling longitudinal advancement and another rudder servomotor for controlling the spin or rotation of this third wheel, and wherein the magnetic drive arrangement Inspection consists of a laser sensor coupled to a linear actuator.
Claims16
A vehicle for external inspection of pipes comprising:
- a base, an upper cover arranged on the base forming a vehicle housing;
- a master card;
- a slave card connected to the master card;
- a pair of preferably straight, left and right magnetic traction wheels;
- a pair of intelligent servomotors each coupled to its corresponding front traction wheel;
- a servomotor housing for receiving or housing the intelligent servomotor;
- a servomotor support of front wheel, wherein the servomotor housing is engaged;
- an encoder on each front traction wheel, each being externally coupled to a front wheel support;
- a wheel bearing by means of which the front wheel drive shaft is coupled to the front wheel support;
- a rear traction wheel longitudinally aligned between the front wheels, the rear traction wheel formed by a rudder servo motor support cover fixed to the base, a support of rudder servo motor coupled to the rudder wheel bearing holder, an intelligent rudder servomotor coupled to the support of rudder servomotor, a rudder wheel bearing holder coupled to the base piece, a rudder bearing, a rear wheel support, which has a circular head coupled to the intelligent rudder servo motor and wherein the rudder bearing is also engaged, so that the rear wheel support is rotatable by controlling said rotation by the intelligent rudder servomotor, said rear traction wheel is coupled to a rear intelligent servo motor, so as to direct the translational advancement of the rear wheel, said rear servo motor is housed in a servo motor housing which is coupled to a rear wheel servo motor support;
- a laser sensor coupled to a slidable linear actuator to inspect the external corrosion of the pipes.
