Description

Technical Field

[0001] The utility model relates to the technical field of crane monitoring, and more specifically to a crane hoisting monitoring device. Background Art

[0002] The left and right outriggers must be supported before the crane starts working. When the road surface is uneven, or the left and right outriggers are of different lengths due to manufacturing errors, the body of the crane will tilt. Working in a tilted state will greatly reduce the lifting capacity of the crane and it is also very unsafe. At present, whether the crane body is level after the outriggers are supported is mostly judged by the operator's experience. A few cranes are equipped with a spirit level, but it can only roughly know whether the vehicle is level. The working conditions of the crane are changeable and complex, and there are often safety hazards.

[0003] A Chinese utility model patent with application number CN202321868637.3 discloses a crane body tilt detection device, including a mounting plate fixed on the crane body by a magnet, a horizontal monitoring component is arranged on the upper end of the mounting plate, a mounting shaft is rotatably connected to the lower end of the mounting plate, a bottom plate is fixedly connected to the outer peripheral surface of the mounting shaft, a tilt sensor connected to the controller is fixedly connected to the lower end of the bottom plate, the mounting shaft is driven to rotate by a driving device connected to the controller so that the bottom plate is dynamically level with the horizontal plane, and a protractor is arranged on the side of the mounting plate away from the driving device, and the center of the protractor coincides with the axis of the mounting shaft. Although the tilt angle of the crane body can be automatically detected by the coordination between the protractor, the driving device and the tilt sensor, the crane body tilt detection device is installed on the crane body by a magnet, and the adsorption force of the magnet during installation will cause the angle of the detection device to be difficult to adjust after installation.

[0004] Therefore, it is necessary to propose a crane hoisting monitoring device to solve the above problems. Utility Model Content
