Abstract

The invention relates to the technical field of tower crane safety equipment, and particularly discloses a tower crane crawling ladder anti-falling device, which comprises a safety fixing strap, a safety belt, a safety belt and a safety belt, the sliding rail penetrates through the stand columns of the crawling ladder, the sliding rail is divided into two sides, and a rack and a clamping block are arranged on one side of the sliding rail in the vertical direction in parallel; the combined wheel is arranged on the sliding rail in a matched mode, the combined wheel comprises a gear and a clamping wheel connected to the side edge of the gear, a connecting rod is rotationally connected to the center position of the gear, the connecting rod is detachably connected with a fixing belt, the other end of the fixing belt is connected with one side of the safety fixing strap, a plurality of clamping blocks are arranged in the clamping wheel, and the clamping blocks are detachably connected with the fixing belt. When a worker misses the step and falls at a high speed, the gear drives the clamping wheel to rotate at a high speed, the clamping block is thrown out under the action of centrifugal force to clamp the clamping block, falling is avoided, the worker does not need to frequently detach the safety catch and then climb upwards again, and time and labor are saved.

本发明涉及塔吊安全设备技术领域，具体公开了一种塔吊爬梯防坠装置，包括：安全固定背带，套接于人体上，用于保护工作人员；滑轨，贯穿所述爬梯的立柱设置，且所述滑轨分成两侧，所述滑轨一侧竖直方向并列开设有齿条和卡位块；组合轮，匹配设于所述滑轨上，所述组合轮包括齿轮和连接于齿轮侧边的卡轮，所述齿轮中心位置转动连接有连接杆，所述连接杆可拆卸连接有固定带，所述固定带的另一端连接所述安全固定背带的一侧，所述卡轮内设有若干卡块，当发生工作人员踩空高速坠落时，所述齿轮带动卡轮高速转动，所述卡块在离心力的作用下被甩出卡住所述卡位块，避免坠落，无需频繁拆下保险扣再重新向上攀爬，省时省力。
