Description

Technical Field

[0001] The utility model discloses a rotary display screen installation mechanism for a large milling machine, belonging to the field of engineering machinery. Background Art

[0002] Milling machines usually have two display screens: the main display screen displays some system parameters, alarms and other information. The secondary display screen is the leveling system display screen. For large milling machines with a milling width of ≥ 2 meters, the operating platform is wide and the field of vision is limited. The operator cannot complete the observation of the construction conditions on both sides in the middle of the console. Therefore, it is necessary to switch between the left and right ends of the console at any time for operation. The display screen needs to move with the personnel (that is, when the personnel operate on the left, the display screen needs to be moved to the left, and when the personnel operate on the right, the display screen needs to be moved to the right). At the same time, it is necessary to consider the possible interference between the display screen and the folding and lowering of the console canopy in the transport mode. At the same time, when the leveling system is zeroed before the construction of the milling machine, it is necessary to observe the construction site at a close distance. The personnel may operate next to the fuselage. Therefore, the display screen of the leveling system has a quick-disassembly requirement, that is, the console can be taken down at any time, and the operation can be carried out next to the fuselage. After the zeroing is completed, the console can be installed back. Summary of the invention
