Bucket-descending-preventing protection device of mixer

Abstract

The invention relates to a bucket-descending-preventing protection device of a mixer. The bucket-descending-preventing protection device comprises an L-shaped rotary rack, a rotary rack support, a linear guide rail, a push ring, a sliding block, a sliding block mounting seat and a driving device; the L-shaped rotary rack is composed of an L-shaped plate and a push plate connected to the top end of the L-shaped plate, and the angle alpha between the push plate and a longitudinal plate of the L-shaped plate ranges from 100 degrees to 160 degrees; the L-shaped rotary rack is mounted on the rotary rack support through a pin shaft I, the sliding block is mounted on the linear guide rail in a sleeving mode and connected with the sliding bock mounting seat, and the push ring is mounted on the sliding block mounting seat through a rotary shaft; the driving device is connected with the sliding block mounting seat. In a loosened state, the push ring abuts against the push plate of the L-shaped rotary rack; in a locked state, the push ring abuts against the L-shaped plate of the L-shaped rotary rack. According to the bucket-descending-preventing protection device, protection is carried out aiming at stirring bucket descending caused by oil cylinder leakage through automatic driving of the driving device, normal operation of equipment is guaranteed, and operation convenience and equipment reliability are improved.

Description

technical field [0001] The invention relates to an anti-dripping protection device for a mixer. Background technique [0002] At present, in the stirring and mixing liter barrel equipment used in the chemical industry, electronic slurry and other industries, the liter barrel oil cylinder is generally used to drive the bracket connection seat to realize the lifting of the mixing barrel. In the liter barrel setting of this structure, there are It leads to the problem of the drop of the mixing tank, which greatly reduces the stability of the equipment. Therefore, it is often necessary to use a bolt connection method to manually tighten the bracket connection seat and the frame; or use a cylindrical pin to prevent the lifting bracket and the mixing tank from falling. The disadvantage of manually tightening the bolts to connect the bracket connection seat and the frame is that it increases the complexity of the operation, or the mixing tank is damaged due to forgetting to loosen...

AI Technical Summary

Problems solved by technology

The disadvantage of manually tightening the bolts to connect the bracket connection seat and the frame is that it increases the complexity of the operation, or the mixing tank is damaged due to forgetting to loosen the bolts and directly descends; the disadvantage of the cylindrical pin clamping method is that the oil cylinder is deformed after leakage Unable to exit, causing the device to malfunction
