Problems solved by technology

[0004] The inventors have found that the joints of the current multi-degree-of-freedom pan / tilt are connected in series, which leads to a large moment of inertia of the load on the first joint axis, resulting in a decrease in dynamic performance or a large drive power; in addition, the power supply between the joints Or the communication cable swings back and forth with the movement of the joint, and there are problems of cable entanglement and fatigue damage

Embodiment 1

[0034] The full-fixed cable two-degree-of-freedom large-load electric pan / tilt of this embodiment includes a base component, a turntable component, a pitch component, a first drive component, and a second drive component;

[0035] The first drive part and the second drive part are installed on the base part in parallel; the first drive part is used to adjust the pitch angle of the pitch part relative to the turntable part; the second drive part is used to drive the turntable part relative to Adjust the yaw angle in the horizontal plane on the base part;

[0036] This embodiment adopts a structure in which the first drive part and the second drive part are installed in parallel on the base part, which significantly reduces the moment of inertia of the turntable part, thereby improving the dynamics of the turntable yaw motion and reducing the yaw drive of the turntable. Motor power and energy consumption.

[0037] The cables and signal lines in the first driving part are collec...

Embodiment 2

[0056] This embodiment also provides a device, which includes the fully fixed cable two-degree-of-freedom large-load electric pan-tilt as described in the first embodiment.

[0057] The full-fixed cable two-degree-of-freedom large-load electric pan / tilt of this embodiment adopts the method of parallel arrangement of two joint drives, which reduces the moment of inertia of the load on the first joint axis, and also avoids the problems of cable winding and fatigue damage.

Abstract

The invention belongs to the technical field of pan-tilts, and provides a full-fixed cable two-degree-of-freedom large-load electric pan-tilt and equipment. Wherein, the platform includes a base part, a turntable part, a pitch part, a first drive part and a second drive part; the first drive part and the second drive part are installed in parallel on the base part; The pitching part is used to adjust the pitch angle relative to the turntable part; the second drive part is used to drive the turntable part to adjust the yaw angle in the horizontal plane relative to the base part; the cables and signal lines in the first drive part Collected into the first drive component cables to be connected to the drive control unit of the first drive component to form a closed-loop control loop of the first drive component; the cables and signal lines in the second drive component are collected into the second drive component The cable is connected to the driving control unit of the second driving part to form a closed-loop control loop of the second driving part.

Description

technical field [0001] The invention belongs to the technical field of pan-tilts, and in particular relates to a full-fixed cable two-degree-of-freedom large-load electric pan-tilt and equipment. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the rapid development of machine vision, wireless communication and automation technology, visual sensors on ground mobile equipment and aircraft, directional transmitting or receiving devices in various fields, high-pressure water guns on fire-fighting robots, surveillance cameras or searchlights in fixed places, etc. During the work process, it is necessary to frequently adjust the posture or perform continuous trajectory tracking. Usually, only two azimuth angles of horizontal rotation and pitch need to be adjusted to meet the work requirements. At this time, a two-degree-of-freedom gimbal c...
