Abstract

The invention discloses a soft canopy automatic covering system of a chain rail type dump truck. The system is characterized by comprising a motor, a transmission shaft, a piece of sot canopy cloth, guide rails, drive sprockets and driven sprockets; the guide rails are respectively arranged two sides of a carriage; canopy rod brackets are matched on the guide rails; the canopy rod brackets are connected with the guide rails through a roller group; two canopy rod brackets on the same guide rail are connected by a fastening chain; the lower end of the last canopy rod bracket on the same guide is connected with a transmission chain through a chain locking device; a group of sprockets are arranged under the same guide rail; one end of the transmission chain is connected with the drive sprocket, and the other end of the transmission chain is connected with the driven sprocket; the two drive rotating wheels are connected through a synchronous transmission shaft; the synchronous transmission shaft is connected with the motor; and the motor is connected with a control system. As the positive and negative rotation directions are controlled, the expansion or contraction of the soft canopy cloth can be flexibly controlled, the expanding length is not limited, and the contracted canopy rods occupy small space are convenient to fix.
