The invention relates to the technical field of pantograph lifting devices, and discloses a protection device for effectively protecting a pantograph lifting device during high-speed driving. The protection device comprises a base, and a movable groove is formed in the base. According to the protection device for effectively protecting pantograph lifting device during high-speed driving, a motor drives a rotating shaft to rotate through a transmission shaft, a rotating block is fixedly connected to the rotating shaft, a third-stage supporting rod is fixedly connected to the rotating block, and the bottom end of a baffle is fixedly connected to the third-stage supporting rod, so that the rotating shaft rotates to slowly lift a baffle plate. The upper end of the baffle plate is fixedly connected with a second-level supporting rod, the second-level supporting rod rises along with the baffle plate. When the second-level supporting rod moves to the dead angle of the supporting rotating shaft, the first-level supporting rod is pushed to move backwards, the first-level supporting rod is connected with a connecting rod and a sliding block, and when the sliding block moves to the position of a left ejector block, the second-level supporting rod is fixed and cannot move. The upper end of the baffle plate is fixed. The pantograph lifting device can be effectively protected after the baffle plate is completely fixed.
本发明涉及升弓装置技术领域,且公开了一种在高速行驶中有效保护升弓装置的防护装置,包括底座,所述底座的内部开设有活动槽。该在高速行驶中有效保护升电后弓的防护装置,电机马达通过传动轴带动转轴转动,转块固定连接在转轴上,三级支撑杆固定连接在转块上,挡板的底端固定连接在三级支撑杆上,所以转轴的转动会缓慢升起挡板,挡板的上端固定连接有二级支撑杆,二级支撑杆随挡板一起升起,当二级支撑杆移动到支撑转轴的死角时会推动一级支撑杆向后移动,一级支撑杆与连接杆和滑块相连接,当滑块移动到左顶块处时,二级支撑杆固定完毕无法移动,实现了挡板的上端固定,挡板完全固定后可以有效的保护升弓装置。
