The anti-falling pulley block provided by the invention not only solves the problem that a rope falls off when the pulley is lifted to a high position in the hoisting process, but also can brake when the extension and release are too fast, plays a role in lubricating the rope bent by passing through the pulley for a long time, and is convenient to recover after braking is finished, so that the hoisting efficiency is improved. According to the technical scheme, the hoisting device comprises a hoisting frame and a hoisting box located below the hoisting frame, the hoisting frame and the hoisting box are connected through a pulley block, and a hoisting ring is fixedly connected to the lower end of the hoisting box. A lower pulley which corresponds to the upper pulley in position and is obliquely arranged is arranged in the hoisting box, a hoisting wire is arranged between the upper pulley and the lower pulley, and the hoisting wire inlet and outlet part of the lower pulley corresponds to the upper pulley in position.
本发明提供的一种防脱型滑轮组,不仅解决了在进行吊装过程中滑轮的升降到高处时绳索脱落的问题,同时还能够对伸缩放出过快时进行制动,同时对长时间经过滑轮弯曲的绳索起到润滑的作用,同时在制动结束后方便恢复,其解决的技术方案是,包括吊装架,起吊箱位于吊装架下方,起吊架与起吊箱之间经滑轮组进行连接,起吊箱下端固定连接有吊环,其特征在于,所述滑轮组包括位于吊装架上横向转动连接的多个上滑轮,起吊箱内设有与上滑轮位置相对应且斜向布置的下滑轮,上滑轮和下滑轮之间设有起吊线,下滑轮起吊线进出部位分别与上滑轮位置相对应。
