Boarding trestle fixed on ocean platform
The invention relates to the technical field of hydraulic engineering, in particular to a boarding trestle fixed to an ocean platform, which comprises a trestle system and a boarding buffer device, the trestle system comprises an internal tooth slewing bearing, a base, a front telescopic frame and a rear pitching frame, the base is fixedly connected with an inner ring of the internal tooth slewing bearing, and the base is fixedly connected with an outer ring of the internal tooth slewing bearing; the rear pitching frame is driven by the inner tooth slewing bearing to rotate and driven by the pitching driving device to do pitching motion, the front telescopic frame slides along the rear pitching frame, the boarding buffering device comprises an upper frame, a lower frame, a buffering air cylinder, a universal joint and a buffering roller, the upper frame is fixedly installed at the front end of the front telescopic frame, the lower frame is hinged to the upper frame, and the buffering air cylinder is fixedly installed at the front end of the front telescopic frame. The buffering air cylinder is a passive air cylinder hinged to the upper frame, the universal joint is installed at the lower end of the lower frame, and the buffering roller is connected with the universal joint. According to the device provided by the invention, the acting force of the boarding trestle on the ocean platform main body is reduced, and the safety and convenience of working personnel boarding the ocean platform are improved.
本发明涉及水利工程技术领域，尤其涉及一种固定于海洋平台的登临栈桥，包括栈桥系统及登临缓冲装置，栈桥系统包括内齿回转支承、底座、前部伸缩框架及后部俯仰框架，底座与内齿回转支承的内环固接，后部俯仰框架由内齿回转支承驱动旋转并由俯仰驱动装置驱动俯仰运动，前部伸缩框架沿后部俯仰框架滑动，登临缓冲装置包括上框架、下框架、缓冲气缸、万向节及缓冲滚筒,上框架固装于前部伸缩框架前端，下框架与上框架铰接，缓冲气缸为被动气缸铰装于上框架上，万向节安装在下框架下端部，缓冲滚筒与万向节连接。本发明提供的装置降低了登临栈桥对海洋平台主体造成的作用力，提高了工作人员登临海洋平台工作的安全性和方便性。
