Description

Technical Field

[0001] The utility model relates to the technical field of crane monitoring devices, in particular to a crane safety monitoring device. Background Art

[0002] Crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called overhead crane, overhead crane, and crane. Cranes are used intensively in some large shipyards, ports and other places. In some occasions, cranes work alternately during use. The operators are inside the operating room and cannot observe the front of the crane's travel direction and the side of the hoisted goods well. They cannot detect obstacles in time, so there are certain safety hazards. Therefore, it is urgent to design a crane safety monitoring device.

[0003] In order to solve the above technical problems, a Chinese utility model patent with the authorization announcement number CN215479264U discloses a crane safety monitoring device. When the monitoring device is used, the electric telescopic rod can drive the slider to move, the slider movement will drive the slideway movement, and the slideway movement will drive the camera movement. Since the camera and the connecting block are hinged, the monitoring angle of the camera can be adjusted, further increasing the monitoring range, avoiding the current monitoring device without the function of adjusting the angle, resulting in the occurrence of monitoring blind spots, thereby improving the use effect of the monitoring device;

[0004] Although the technical solution provided by the utility model solves the problem of blind spots in monitoring when the existing crane monitoring device is in use, in the above solution, when the angle of the monitoring device needs to be adjusted, the camera can only be driven to adjust the vertical angle by controlling the extension of the electric telescopic rod. In actual use, there are blind spots in monitoring not only in the vertical direction, but also in the horizontal direction. If the angle of the camera can only be adjusted in a single direction, there will still be safety hazards, and it is not convenient to use. Utility Model Content
