The invention discloses a three-degree-of-freedom displacement platform for a ship, which comprises a platform surface which is always parallel to a base, the platform surface is connected with threemovable seats through connecting rod assemblies, the three movable seats are installed on three screw rods in a matched mode through thread pairs respectively, guide sleeves are arranged on the threemovable seats respectively, the guide sleeves are arranged on guide columns in a sleeving mode. The connecting rod assembly comprises a connecting rod and a Steffe hinged support, one end of the connecting rod is connected with the table top, the other end of the connecting rod is connected with the movable base through the Steffe hinged support, the upper end of the guide column is fixed to the upper end plate, the motor is fixed to the upper end of the upper end plate, the output end of the motor is connected with the lead screw, and the lower end of the guide column is fixed to the lower end plate. And the lower end plate is fixed on the base. According to the displacement platform, miniaturization of the marine three-degree-of-freedom displacement platform can be achieved, the three-degree-of-freedom displacement amount generated by the sea condition to a ship, especially the large-lift displacement amount generated by the sea condition to the ship, is compensated, and the safety of platform operation on the ship is improved.
本发明公开了一种船用三自由度位移平台,包括与底座始终保持平行状态的台面,所述台面经连杆组件与3个活动座连接,3个活动座均经螺纹副分别配合安装在3根丝杆上,所述的3个活动座上均设有导套,导套套装在导柱上,所述连杆组件包括连杆和史蒂夫铰座,连杆的一端与台面连接,连杆的另一端经史蒂夫铰座与活动座连接,所述导柱的上端固定在上端板上,上端板的上端固定有电机,电机的输出端与丝杆连接,所述导柱的下端固定在下端板上,下端板固定在底座上。该位移平台可实现船用三自由度位移平台的小型化,补偿海况对船舶产生的三自由度位移量,特别是海况对船舶产生的大升程的位移量,提高了船舶上平台作业的安全性。
