Heavy-load cradle head

Abstract

A heavy-duty cloud platform, comprising: a base, a core, a casing, a shield, and a transmission mechanism, and gravity compensation parts are respectively arranged on the end plates on both sides, and the gravity compensation parts and the shield connection plates are respectively arranged on the vertical transmission shaft and the Both sides of the end plate fixed position. By changing the weight of the gravity compensation part, the moment generated by the gravity compensation part can be equal to the moment generated by the camera and the shield connecting plate, so that the overall center of gravity of the shield structure connected to the camera falls on the center of the horizontal transmission shaft, that is On the load-bearing center of the entire heavy-duty head. When the camera rotates in the vertical direction, since the camera and the protective cover are rotating in a state of gravity balance, the camera can smoothly complete the angle conversion in the vertical direction, so that the shooting picture of the camera is more stable.

Description

technical field [0001] The present invention relates to the technical field of video cameras, specifically, a gravity compensation part is arranged on the end plates on both sides, and the center of gravity of the camera is kept stable during operation by changing the weight of the gravity compensation part, so that the vertical direction of the camera is Smooth-running heavy-duty head. Background technique [0002] The PTZ is a camera installation platform composed of two AC motors, which can drive the camera to move horizontally and vertically. There are two motors inside the gimbal, which are responsible for the up and down and left and right rotations of the gimbal respectively. The difference in working voltage also determines the overall working voltage of the gimbal, generally there are AC 24V, AC 220V and DC 24V. When receiving the up and down action voltage, the vertical motor rotates and drives the vertical transmission wheel to rotate through the reduction box; ...

AI Technical Summary

Problems solved by technology

[0009] In the actual use of the prior art heavy-duty pan / tilt combined with the camera, due to the heavy weight of the camera and the shield, the gravity distribution at the structure position of the shield is unbalanced, and its center of gravity deviates from the horizontal rotation of the movement The center, that is, deviates from the load measurement position of the heavy-duty head, so that the camera installation is not stable enough. When the camera starts to work in the vertical direction, the motor in the movement must first overcome the huge torque caused by the gravity of the camera. Due to the influence of inertia, the camera will produce an unstable working state when it is running or stopping, and this instability is particularly prominent when the camera is running at high speed and at a magnification.
