The invention mainly relates to the field of grandstands, in particular to a hydraulic lifting type multifunctional grandstand with multiple safety protection. The device comprises a bottom frame, an outer shear fork supporting rod, an inner shear fork supporting rod and a bearing plate. Pulleys are arranged at the bottoms of the outer shear fork supporting rods in pairs and arranged on the bottom frame in a sliding mode. A hydraulic driving device is arranged between the inner shear fork supporting rod and the outer shear fork supporting rod; the stand further comprises a screw driving device, the screw driving device comprises a connecting rod, a threaded rod and a driving motor, and the connecting rod is arranged at the bottom of the outer shear fork supporting rod. A threaded hole is transversely formed in the connecting rod, a threaded rod is in threaded connection with the interior of the threaded hole, and the threaded rod is connected to the driving motor. By adopting a dual-driving mode of the hydraulic driving device and the screw driving device, stable lifting of the grandstand is realized, and when a hydraulic system fails, the screw driving device can be used as a standby system to ensure that the grandstand can be safely fixed at a certain position, so that the safety and the reliability of the grandstand are greatly improved.

    本发明主要涉及看台领域,具体的说是一种多重安全防护的液压升降式多功能看台。本发明包括底架、外剪叉支杆、内剪叉支杆和承载板;外剪叉支杆的底部成对设置有滑轮,滑轮滑动设置于底架上;内剪叉支杆和外剪叉支杆之间设置有液压驱动装置;本看台还包括螺杆驱动装置,螺杆驱动装置包括连接杆、螺纹杆和驱动电机,连接杆设置于外剪叉支杆的底部;连接杆上横向开有螺纹孔,螺纹孔内螺纹连接有螺纹杆,螺纹杆连接于驱动电机上。本发明通过采用液压驱动装置和螺杆驱动装置的双重驱动方式,实现了看台的平稳升降,并在液压系统失效时,螺杆驱动装置可以作为备用系统,确保看台能够安全地固定在某一位置,大大提高了看台的安全性和可靠性。
