The invention relates to an external climbing safety protection device for a control tower crane, in particular to the technical field of control tower crane protection, which comprises a lifting device, a climbing frame and an anti-falling device. Synchronous meshing of the two climbing gears and the tooth edge sliding rail is guaranteed through the arranged driving motor and transmission gear, double-side meshing lifting points are formed, traditional single-side meshing is replaced, the lifting stability of the lifting device is improved, meanwhile, the probability of falling of the lifting device is reduced by increasing meshing force bearing points, and the lifting device is convenient to use. In addition, the service life of the lifting device is prolonged; when the lifting device suddenly falls, the first ratchet wheel and the second ratchet wheel are blocked by the first ratchet wheel and the second ratchet wheel, falling of the lifting device can be interrupted, meanwhile, the two second ratchet wheels and the first ratchet wheel are integrally distributed in a triangular shape, a stable triangular anti-falling area is formed, stress is evenly distributed, and therefore the lifting device stably stops falling.
本发明涉及一种用于塔台起重机的外爬升安全防护装置,具体涉及塔台起重机防护技术领域,包括:升降装置、攀爬架和防坠装置。本发明通过设置的驱动电机和传动齿轮保证了两个爬升齿轮和齿边滑轨的同步啮合,形成了双侧啮合升降点,以此代替传统的单侧啮合,不仅利于提高升降装置的升降稳定性,同时还通过增加啮合受力点来减小升降装置发生下坠的概率,此外也利于提高升降装置的使用寿命;当升降装置突发下坠时,棘爪一、棘爪二对棘轮一、棘轮二的阻挡可中断升降装置的下坠,同时两个棘轮二和棘轮一整体呈三角形分布,形成稳定的三角形防坠区且受力分布均匀,使得升降装置稳定的停止下坠。
