Lifting hook monitoring device for tower crane

Abstract

The invention discloses a lifting hook monitoring device for a tower crane, and relates to the technical field of lifting hook monitoring. The lifting hook monitoring device comprises a base, the left side of the top of the base is fixedly provided with a fixing plate, the right side of the fixing plate is fixedly provided with a driving motor, the output end of the driving motor is fixedly provided with a telescopic rod, a movable plate is fixedly mounted on the right side of the telescopic rod, a left supporting plate is fixedly mounted on the left side of the top of the fixed plate, a fixed frame is fixedly mounted on the right side of the left supporting plate, a fixed rod is fixedly mounted in the fixed frame, and a lifting hook body is fixedly mounted on the outer side of the fixed rod. According to the lifting hook monitoring device for the tower crane, the driving motor and the telescopic rod are arranged, the movable plate is pushed to move, pulling force is generated on a lifting hook body and a lifting hook neck, a control displayer is arranged, whether the lifting hook body deforms under ultimate pulling force or not is monitored, and therefore whether the lifting hook body is qualified or not is detected.

Description

Technical field[0001]The present invention relates to the field of hook monitoring, and is specifically a hook monitoring device for tower cranes.Background technique[0002]Tower crane is a lifting device on the construction site, also known as "tower crane", hooks are the most used spreaders in lifting equipment, which is required to hang on the steel wire rope of the lifting mechanism by means of a tube set. Items, and once the hook is damaged, it is very important to cause major personal injury and death, so the safety of hooks is very important to the lifting machinery.[0003]Current hooks during use, hook normal performance defects, materials are not met, mechanical wear, etc., in the lifting weight, and it is difficult to find hook in daily detection of hooks. The deformation occurred during use, resulting in an accident that has been detached from the hook, thereby causing personal casualties and property damage.Inventive content[0004]It is an object of the present invention to...

AI Technical Summary

Problems solved by technology

[0003] During the use of the current hooks, the hooks often deform greatly when lifting heavy objects due to performance defects, substandard materials, mechanical wear, etc., and it is difficult to find the hooks in the daily inspection of the hooks. Deformation during use leads to accidents in which heavy objects fall off the hook, resulting in casualties and property losses
