The invention relates to a pulley fixing device and a lifting device. The pulley fixing device comprises a pulley which comprises a first protective plate and a second protective plate which are oppositely arranged in the first direction and connected with each other, and an interlayer space is defined between the first protective plate and the second protective plate; the limiting assembly is connected to the first protection plate and the second protection plate and located in the interlayer space. The fixing plate is used for being arranged on a connecting structure of the whole string of insulators to be replaced and a high-altitude wire; wherein the pulley is provided with a first end and a second end, and the second end is closer to the fixing plate than the first end; a limiting structure is arranged at one end of the fixing plate close to the second end; the interlayer space is configured to be capable of containing part of the fixing plate, the limiting structure is exposed out of the interlayer space so that the limiting structure can be connected to the first protection plate and the second protection plate in a clamped mode, and the limiting assembly can abut against the fixing plate. According to the technical scheme, the fixing stability of the tackle on the high-altitude fitting can be improved, and the operation risk is reduced.
本申请涉及一种滑车固定装置及起重装置。该滑车固定装置包括:滑车,包括沿第一方向相对设置且彼此连接的第一护板和第二护板,第一护板和第二护板之间限定出夹层空间;限位组件,连接于第一护板和第二护板,且位于夹层空间内;及固定板,用于设于待更换整串绝缘子与高空导线的连接结构上;其中,滑车具有第一端和第二端,第二端较第一端更靠近固定板设置;固定板靠近第二端的一端设有限位结构;夹层空间配置为能够容置部分固定板,且限位结构外露于夹层空间,以使限位结构卡接于第一护板和第二护板上,限位组件能够抵靠于固定板上。本申请的技术方案能够提高滑车在高空金具上固定的稳定性,降低操作风险。
