Heavily loaded The Cloud Terrace of the present invention comprises: base, fix with the preset position of video camera, and support heavily loaded The Cloud Terrace and video camera; Movement constitutes the driving and the running part of heavily loaded The Cloud Terrace; Shell is arranged on outside the movement, surrounds and the protection movement; Guard shield is made of with the guard shield web joint that is connected end plate the end plate that is separately positioned on the shell both sides, and video camera is fixed on the guard shield web joint; Gear train, be divided into horizontal drive shaft and vertical drive shaft, movement is connected with end plate with base respectively, video camera is rotated simultaneously in the horizontal and vertical directions, gravity compensation portion is set respectively on the end plate of both sides, and gravity compensation portion and guard shield web joint are separately positioned on the both sides of vertical drive shaft and end plate fixed position.
The present invention can also adopt following technical measures:
The weight of described both sides gravity compensation portion is adjusted according to the weight of video camera and the weight distribution situation of guard shield.
The end plate that described gravity compensation portion and its are positioned at the vertical drive shaft homonymy equals to be fixed with the moment of the end plate of the guard shield web joint of video camera and respective side with respect to the vertical drive shaft fixed position with respect to the moment of vertical drive shaft fixed position.
Advantage and good effect that the present invention has are:
In the heavily loaded The Cloud Terrace of the present invention, both sides at end plate are provided with gravity compensation portion respectively, gravity compensation portion is that axle forms moment with the vertical drive shaft by end plate, by changing the weight of gravity compensation portion, can make the moment of gravity compensation portion generation and the moment equal and opposite in direction of video camera and the generation of guard shield web joint, thereby the whole center of gravity that makes the shield structure that has connected video camera falls within the center of horizontal drive shaft, promptly in the load-bearing of whole heavily loaded The Cloud Terrace in the heart.When video camera when vertical direction is rotated, because video camera and guard shield are in the state of gravitational equilibrium in rotation, the moment that video camera gravity produces is offset by the moment of gravity compensation portion, inertia when video camera rotates also is greatly reduced, the motor of movement need not to overcome the huge moment that video camera gravity produces just can make the video camera rotation, make video camera can finish angular transition on the vertical direction stably, thereby make the shooting picture of video camera more stable.
