The invention discloses a pull bucket with a self-locking function and capable of preventing a steel wire rope from being broken. The pull bucket comprises a pull bucket body, the steel wire rope anda rail matched with the steel wire rope; a fixing block and a control box are arranged on the pull bucket body, a locking mechanism is arranged on the rail, the locking mechanism slides along the rail, and the fixing block is connected to the locking mechanism; a wireless signal receiving device and a controller are arranged in the control box, and the locking mechanism is connected with the controller; and a tensioning force detection mechanism and a wireless signal transmitting device are arranged on the steel wire rope. According to the pull bucket, the tensioning force of the steel wire rope is monitored at any time through the tensioning force detection mechanism and the wireless signal transmitting device, and it is determined that the tensioning force is within an allowable range; and the control box and the locking mechanism are arranged on the pull bucket, the wireless signal receiving device and the controller are arranged in the control box, when the tensioning force of thesteel wire rope is smaller than the allowable range, the wireless signal transmitting device transmits an alarm signal to the wireless signal receiving device and transmits a shutdown locking signal to the controller, and the pull bucket is locked on the rail through the locking mechanism, so that the pull bucket is prevented from falling rapidly to ensure the reliability and the safety of the pull bucket.
