Camera bearing device and control method thereof

Abstract

The invention relates to a camera bearing device and a control method thereof. The camera bearing device comprises a lifting arm assembly; the holder is mounted at the lifting end of the lifting arm assembly and used for supporting a camera; the lifting arm assembly comprises a fixed arm and a multi-stage lifting arm, the fixed arm is internally provided with a hollow lifting channel, the fixed arm is fixedly arranged, and the lifting arm and the fixed arm as well as the lifting arms at all stages are sleeved in a lifting sliding manner; the lifting arm assembly further comprises a lifting steel cable mechanism and a linkage steel cable mechanism, the fixed arm and the lifting arms are in transmission connection through the lifting steel cable mechanism, the multiple stages of lifting arms are in transmission connection through the lifting steel cable mechanism, and the lifting arms are driven by the lifting steel cable mechanism to ascend and descend. The fixed arm and the lifting arms as well as the multiple stages of lifting arms are in transmission connection through linkage steel cable mechanisms, and synchronous lifting of the lifting arms at all stages is achieved through the linkage steel cable mechanisms. The camera bearing device can perform more-stage transmission and larger-range lifting, and is more stable and reliable.

Description

technical field [0001] The present invention relates to the technical field of video equipment, in particular to a camera carrying device and a control method thereof. Background technique [0002] In the radio and television industry, there is a need for shooting, which is to achieve a stable rise or fall of the camera in the vertical height, to ensure the process of rising or falling, and the whole picture can be used as the broadcast picture, and no shaking, shaking and other phenomena that affect the shooting effect are allowed. . This just needs a kind of camera carrying device to realize this function. [0003] In the prior art, usually the mechanical structure of the lifting part is mainly realized by a screw rod. Generally, it will be made into a multi-stage screw. In such a structure, the lifting height depends on the odd number of the screw and the length of the screw. The lifting speed depends on the motor speed and the pitch of the screw. In actual production ...

AI Technical Summary

Problems solved by technology

In actual production and processing, the longer the screw rod, the more difficult the processing, and the motor speed is also limited. Breaking through the lifting height and lifting speed, it is unrealistic to simply use a higher production process and a higher speed drive motor. A better structural design
