The invention discloses a coal grab bucket with high safety. The coal grab bucket comprises an upper bearing beam, a bucket body arranged below the upper bearing beam and supporting rods symmetricallyarranged at the two ends of the upper bearing beam and connected with the bucket body. A beam lifting device is arranged on the upper bearing beam, and rope guide devices are arranged on the two sides of the beam lifting device; fixing plates are symmetrically arranged on the lower side of the upper bearing beam, and upper pulley blocks are arranged on the fixing plates; a steel cable bypasses the upper pulley blocks and a lower pulley block through the rope guide devices of the upper bearing beam and controls the supporting rods upwards and downwards through a mechanical structure, and the supporting rods act to drive a first connecting plate and a second connecting plate, so that a first petal body and a second petal body in the bucket body are opened and closed. Coal is grabbed throughopening and closing of the first petal body and the second petal body, and meanwhile each structure is provided with a fixing pipe set and a connecting rod set for structural reinforcement. The coalgrab bucket is simple in structure, safe and stable.
