The existing crane can move along the track and has a telescopic function, but does not have a rotating function, resulting in the inability of the fire fighting and rescue cabin to accurately reach the designated position. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a rotating structure of an intelligent fire fighting jib, which increases the movement direction of the telescopic jib and enables the fire fighting cabin to quickly and accurately reach the designated position.

[0004] To solve the above technical problem, the technical solution of the utility model is: a rotating structure of an intelligent fire fighting jib, including a track provided on the roof of a building, an AGV roof crane running on the track, and a telescopic jib provided on the AGV roof crane; a rotating mounting platform is provided on the AGV roof crane, and the telescopic jib is mounted on the AGV roof crane through the rotating mounting platform; the rotating mounting platform includes a platform plate, an internal gear slewing bearing provided between the platform plate and the AGV roof crane, and a speed regulating mechanism for driving the internal gear slewing bearing. The outer ring of the internal gear slewing bearing is fixedly connected to the platform plate, the inner ring of the internal gear slewing bearing has internal teeth and is fixedly connected to the AGV roof crane, and the speed regulating mechanism includes a gear meshing with the inner ring of the internal gear slewing bearing and a motor for driving the gear, and the motor is fixed on the platform plate. The principle of the utility model: The AGV roof crane carries the telescopic jib and moves along the track, enabling the fire fighting cabin to walk around the outer wall of the building. The telescopic jib cooperates with the winch to enable the fire fighting cabin to lift and lower on the outer wall of the building. The telescopic jib is provided on the rotating mounting platform, and the rotating mounting platform can drive the telescopic jib to rotate, thereby driving the fire fighting cabin to deflect at an angle. With the cooperation of multiple movements, the fire fighting cabin can quickly and accurately reach the designated position.

[0005] As an improvement, the outer ring of the internal gear slewing bearing is fixed to the bottom of the platform plate by bolts, and the inner ring of the internal gear slewing bearing is fixed to the top of the AGV rooftop vehicle by bolts.

[0006] As an improvement, the telescopic jib is of a double-arm structure.

[0007] The beneficial effects brought by the present utility model compared with the prior art are as follows:

[0008] The AGV rooftop vehicle carries a telescopic jib and travels along the track, enabling the fire fighting cabin to travel around the outer wall of the building. The telescopic jib, in cooperation with the winch, can lift and lower the fire fighting cabin on the outer wall of the building. The telescopic jib is arranged on the rotary mounting platform, and the rotary mounting platform can drive the telescopic jib to rotate, thereby driving the fire fighting cabin to deflect at an angle. With the cooperation of multiple movements, the fire fighting cabin can quickly and accurately reach the designated position. BRIEF DESCRIPTION OF THE DRAWINGS
