Abstract

A feeding device for subway grille main reinforcement conveying includes two-layer chain plate conveyor arranged at an upper and a lower interval, and 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 chain plate conveyor provides power through a motor reducer connected to a drive sprocket of the chain plate conveyor, and a higher end of the chain plate conveyor is provided with a position detection sensor. The position detection sensor can detect the position of the main reinforcement, and control the start and stop of the motor reducer and the grasping of the main reinforcement by a manipulator through feeding back the position of the main reinforcement to a main control system.

Claims (7)

1. 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.

2. The feeding device for subway grille main reinforcement conveying according to claim 1 , wherein the two sets of chain plate conveyors on a same layer are driven by the same motor reducer, the drive sprockets of the two sets of chain plate conveyors on the same layer are arranged correspondingly, and the correspondingly arranged several drive sprockets achieve torque transmission and maintain synchronization through a connecting shaft.

3. The feeding device for subway grille main reinforcement conveying according to claim 1 , wherein the chain plate conveyor is arranged in a form of a horizontal-inclined type, and the chain plate on a lower side of the chain plate conveyor is arranged in a horizontal state as a placement area of the main reinforcement.

4. The feeding device for subway grille main reinforcement conveying according to claim 1 , wherein the mounting hole and the limit block are provided with mutually compatible threads, and the limit block is screwed in the mounting hole.

5. The feeding device for subway grille main reinforcement conveying according to claim 1 , wherein a photoelectric induction sensor is selected for the position detection sensor.

6. The feeding device for subway grille main reinforcement conveying according to claim 1 , wherein both ends of the lower chain plate conveyor exceed a certain distance from the end of the upper chain plate conveyor.
