Feeding device for subway grille main reinforcement conveying

A feeding device for subway grille main reinforcement conveying, comprising two-layer chain plate conveyor arranged at an upper and a lower interval, the chain plate conveyor is a climbing structure with one end high and one end low, two ends of the chain plate conveyor are fixedly connected to a support frame, and the chain plate conveyor is erected on a working plane through the support frame, the upper and lower two-layer chain plate conveyor provides power through a motor reducer connected to a drive sprocket of the chain plate conveyor, a higher end of the chain plate conveyor is provided with a position detection sensor, the position detection sensor is configured to detect a position of a main reinforcement, and control a start and a stop of the motor reducer and a grasping of the main reinforcement by a manipulator through feeding back the position of the main reinforcement to a main control system;

• each layer of chain plate conveyor comprises two sets arranged at left and right interval, and a first gap is provided between the two sets of chain plate conveyors to facilitate the manipulator to explore and grasp the main reinforcement;
• and
• several mounting holes are arranged on a chain plate of the chain plate conveyor in a rectangular array, and some of the mounting holes are configured to be detachably fixed with a limit block, several limit blocks form a clamping array, and the main reinforcement is placed on the chain plate conveyor along a second gap between the limit blocks and is fixed by a clamping of the adjacent limit block, a feeding conveying of the main reinforcement is realized through the two-layer chain plate conveyor arranged at the upper and the lower interval, and a simultaneous transmission of the main reinforcement with two different curvatures is realized through the clamping array formed by the limit blocks.
