Hanging type multi-dimensional movement mechanical arm

The invention discloses a hanging type multi-dimensional movement mechanical arm. The hanging type multi-dimensional movement mechanical arm comprises a transversely-moving walking mechanism, a lifting storage mechanism, a multi-stage lifting mechanism, a swinging rotating mechanism and an installation steel frame, wherein the transversely-moving walking mechanism is arranged on a building load-bearing structure above a stage, the lifting storage mechanism is arranged on the transversely-moving walking mechanism, the multi-stage lifting mechanism is installed on the lifting storage mechanism, the swinging rotating mechanism is installed on the multi-stage lifting mechanism, the installation steel frame is installed on the swinging rotating mechanism, and an LED display or a large prop is arranged on the installation steel frame and can be driven by the transversely-moving walking mechanism, the lifting storage mechanism, the multi-stage lifting mechanism and the swinging rotating mechanism to do the two-direction transversely-moving movement, the perpendicular lifting movement and the three-direction rotating movement. The multi-dimensional movement of the LED display or the large prop can be achieved, the LED display or the large prop can be presented to field audience at the optimal position, height and angle, and the hanging type multi-dimensional movement mechanical arm has the advantages of being large in movement dimension number, wide in movement range, compact in structure, light in dead weight, convenient to store, powerful in use function, easy and convenient to operate and maintain, and the like.
