Safety precaution system for gantry crane

Abstract

The present invention discloses a safety precaution system for a gantry crane. The safety precaution system comprises displacement sensors, a central processing unit, cameras and an electromagnetic valve, wherein the displacement sensors are respectively arranged on the two support legs of the gantry crane and for transmitting the collected support leg information to the central processing unit, the camera is used for collecting the information of the images on the front track and the rear track of the support legs and transmitting the collected image information to the central processing unit, the central processing unit judges the position of the support leg according to the position information of a plurality of the displacement sensors, judges whether the two support legs are positioned in the same horizontal direction, and judges whether the safety hidden danger exists on the track according to the image information collected by the cameras, the electromagnetic valve turns off the power of the gantry crane according to the command of the central processing unit, and when the central processing unit turns off the power of the gantry crane through the electromagnetic valve, the central processing unit concurrently controls the braking system of the gantry crane to compulsively brake so as to achieve the safe production.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a safety protection system for a gantry crane. Background technique [0002] At present, in the field of large-scale cargo handling and ship welding, gantry cranes are commonly used for large-scale equipment hoisting machinery, but in practical applications, many safety accidents are caused by the negligence of the driver, often because The two outriggers of the gantry crane shifted, causing the entire gantry crane to collapse. Contents of the invention [0003] The object of the present invention is to propose a safety protection system for gantry cranes to achieve the advantages of safe production in view of the above problems. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A safety protection system for gantry cranes, including a displacement sensor, a central processing unit, a camera and a solenoid v...
