Passive anti-falling device and lifting system with passive anti-falling device
The invention provides a passive anti-falling device and a lifting system with the passive anti-falling device. The passive anti-falling device comprises a guide rail, a machine base, a trigger gear and a brake pawl, wherein an anti-falling stop lever is arranged on the guide rail, the guide rail is connected with a sliding sleeve of the machine base in a matched mode, the trigger gear is meshed with the anti-falling stop lever, the brake pawl is provided with a balance weight block, and the machine base is provided with a limiting stop block; when the guide rail ascends and descends at a constant speed, the brake pawl and the trigger gear are intermittently meshed, rotate forwards or reversely by a fixed angle and then automatically return under the action of the balance weight; and whenthe guide rail rapidly falls, the trigger gear continuously pokes the brake pawl in a non-return state to rotate reversely, and when the anti-falling stop lever falls on the trigger gear, the brake pawl is limited by the limiting stop block to stop rotating. The passive anti-falling device adopts a passive mode to prevent falling, can be used in a severe working environment, and is not influencedby mud, dust and temperature.
本发明提供一种非能动防坠装置及具有非能动防坠装置的升降系统，其中，非能动防坠装置包括导轨、机座、触发齿轮和制动棘爪，所述导轨上有防坠档杆，所述导轨和机座滑套配合相连，且所述触发齿轮与防坠档杆相互啮合，所述制动棘爪上设有平衡配重块，所述机座上设有限位挡块；所述导轨匀速升降时，制动棘爪与触发齿轮间歇性啮合正向或反向转动固定角度后在平衡配重块的作用下自动回位；所述导轨快速下坠时，触发齿轮持续拨动处于未回位状态下的制动棘爪反向转动，并在防坠档杆落于触发齿轮上时，制动棘爪受到限位挡块的限制停止转动。本发明采用非能动的方式防坠，能使用在恶劣的工作环境中，不受到泥浆、粉尘、温度、温度的影响。
