Abstract

A two-degree-of-freedom hydraulic holder comprises a lower hydraulic oscillating cylinder, an upper hydraulic oscillating cylinder and a bracket, wherein the lower hydraulic oscillating cylinder is connected into a lower oscillating cylinder fixing housing; an output shaft of the lower hydraulic oscillating cylinder vertically extends out of the upper end of the lower oscillating cylinder fixing housing; the upper hydraulic oscillating cylinder is connected into an upper oscillating cylinder fixing housing; an output shaft of the upper hydraulic oscillating cylinder horizontally extends out of the upper oscillating cylinder fixing housing; the upper oscillating cylinder fixing housing is connected to the output shaft of the lower hydraulic oscillating cylinder; a bracket is connected to the output shaft of the upper hydraulic oscillating cylinder. The holder has two rotation degree of freedom, and axes are vertically intersected; the two-degree-of-freedom hydraulic holder is driven through two hydraulic oscillating oil cylinders; an encoder is mounted on the rotating shaft of each hydraulic oscillating oil cylinder and is used for detecting the angular displacement of each oscillating oil cylinder. The wo-degree-of-freedom hydraulic holder is capable of resisting strong electromagnetic interference, high in loading capacity, high in motion stability, high in protection level, and compact in structure.

Description

technical field

[0001] The invention relates to a hydraulic cloud platform with two degrees of freedom of rotation, horizontal and pitch, and belongs to the technical field of cloud platforms. Background technique

[0002] Some large-scale camera or monitoring systems, fire or washing water guns, radars, satellite antennas, etc. need to change or continuously adjust their orientation in space during work, which requires these devices to be installed in two free spaces that can be continuously adjusted and precisely oriented. degree space on the gimbal.

[0003] Chinese patent document CN 101915341A discloses a two-degree-of-freedom pan-tilt mechanism. The pan-tilt adopts a motor drive method, including a base, a horizontal motor and a vertical motor. orientation. However, the load capacity of the electric pan / tilt is generally small. Even if a large-load electric pan / tilt is manufactured by connecting the motor in series with a large reduction ratio device, the structure s...
