Abstract

The invention discloses an explosion-proof ball, which comprises a ball body, a ball cover, a ball cover positioning control arm, a supporting plate and a worm reduction gear. The ball cover positioning control arm is fixedly connected with the supporting plate, and the supporting plate is fixedly connected with the ball cover. The explosion-proof ball is characterized in that an arc-shaped groove at the lower end of a vertical rod of the ball cover positioning control arm is movably connected with central shafts at two ends of the ball body; a swinging rod and a torsion spring are sleeved on a swinging rod shaft hinged with the supporting plate; a chain hinged with the upper end of the swinging rod is sequentially in wrapped connection with a second guide wheel hinged on the ball body, a sprocket wheel fixedly connected onto an output shaft of the worm reduction gear, a first guide wheel hinged on the ball body, and a third guide wheel; the tail end of the chain is hinged with the ball cover; an input shaft of the worm reduction gear is fixedly connected with an output shaft of a speed increaser; an input shaft of the speed increaser is fixedly connected with a hand wheel or a motor; and a supporting wheel hinged with the lower end of the supporting plate is in contact with and matched with a bracket of the ball body. The explosion-proof ball has the advantages that the structure is simple, the ball cover is convenient to be lifted, opened and closed, the action is reliable, the self-locking of the ball cover is firm, the marching bumpiness in various road conditions is not worried, and the like.

Description

technical field [0001] The invention relates to the field of anti-terrorist detonation and is an anti-explosion ball. Background technique [0002] Existing explosion-proof balls usually use a ball cover to be placed inside the sphere, and the switch mechanism of the ball cover controls the ball cover to rise and fall in the sphere and turn around the center axis of the sphere to realize the opening and closing of the ball cover, but the switch mechanism of the ball cover structure are different. China Utility Model Authorization Notice No. CN201331310Y discloses a relatively advanced "An Explosion-Proof Ball". The ball cover switch mechanism of this explosion-proof ball is an external switch mechanism. The upper link drives the push-pull plate to swing back and forth around the center axis of the ball, and pushes and pulls the lifting arm connected to the U-shaped beam on the ball cover through the connecting rod, so that it slides along the guide shaft and swings back and...
