Abstract

The invention provides an anti-falling cover plate. The anti-falling cover plate comprises a cover plate main body, wherein a suspension connection part comprises a suspension cross beam and bolts; two ends of the suspension cross beam press against the outer side wall of a rotary barrel body; the cover plate main body is arranged in an opening in the side wall of the rotary barrel body; and the cover plate main body is connected with the suspension cross beam through the bolts so as to seal the opening of the rotary barrel body. According to the anti-falling cover plate disclosed by the invention, the suspension connection part is suspended and connected to the opening in the side wall of the rotary barrel body; when the rotary barrel body rotates, the bolts press the suspension cross beam on the rotary barrel body; the suspension cross beam suspends the cover plate main body, so that the vibration on the cover plate main body can be dispersed to the suspension cross beam; and therefore, looseness of the bolts is effectively avoided, and falling of the anti-falling cover plate provided by the invention is prevented.

Description

technical field [0001] The invention relates to the technical field of anti-off sealing devices, in particular to an anti-off cover plate. Background technique [0002] The manhole cover is a key component installed on the rotating cylinder of the ball mill. It is fixed on the rotating cylinder of the ball mill by bolts. Since it rotates with the cylinder during work, the bolts are easy to loosen, posing a threat to production safety. Contents of the invention [0003] The main purpose of the present invention is to provide a fall-off prevention cover to solve the problem that the manhole cover is easy to fall off in the prior art. [0004] In order to achieve the above object, the present invention provides a fall-off prevention cover plate, which includes: a cover plate main body; a suspension connection part including a suspension beam and bolts, and the two ends of the suspension beam abut against the outer wall of the rotating cylinder Above: the main body of the cov...
