Transmission limit device for soft cable traction video camera

Abstract

A transmission limit device for a soft cable traction video camera comprises four support tower columns, pulley brackets, drivers, pulley sets, soft cables and a video camera. The four support tower columns are perpendicularly fixed on the ground to form a cuboid space for the video camera to move. One pulley bracket is fixed at the top end of each support tower column and used for fixing one pulley set. Each pulley set comprises a base, a pulley, a pulley shaft and a pulley support, wherein the pulley is arranged on the pulley shaft, two ends of the pulley shaft are fixed on two support lugs of the pulley support, and the pulley rotates around the pulley shaft, the base is provided with a frustum, a mounting shaft is arranged at the center of the frustum and provided with a threading hole, a ball is arranged between the frustum and the pulley support, and the pulley support rotates around the mounting shaft, and the two rotation directions are perpendicular to each other. The soft cables wind on the drivers and are jointly connected to the video camera through the pulley brackets and the pulley sets on the support tower columns. The drivers are fixedly connected to the bottom end of the support tower columns and connected with a computer to control winding and unwinding of the soft cables.

Description

technical field [0001] The invention relates to the technical field of mechanical positioning control, and further relates to a precise positioning control device for a cable-tracted camera, specifically a transmission limit device for a cable-tracted camera. Background technique [0002] At present, there are many kinds of robots in the industry that realize the positioning control of space moving objects. The driving devices for realizing the movement of objects are rigid devices such as hydraulic cylinders, air cylinders, electric cylinders, and rotary joints. Some structures use pulleys. The existing pulley is generally composed of a pulley installed on the pulley shaft and placed on the support. The pulley shaft is fixed relative to the support. The direction of rotation of the rope is perpendicular to the pulley shaft. target control. [0003] Garrett W. Brown applied for a patent "A device for supporting and transmitting a suspension system, such as a camera (SUSPENS...

AI Technical Summary

Problems solved by technology

However, the deficiencies that still exist in this patent are: the position of the driver for pulling the cable is not given, and the structure of the pulley at the top of the supporting tower for changing the direction of the cable is not described

But the deficiencies that still exist in this patent are: the structure is still relatively complicated, there is no device for reducing friction at the rotation of the pulley seat, the friction force is relatively large, and the pulley seat is easy to damage
