The invention provides a climbing device for carrying people on a tower crane.The climbing device comprises a tower crane body and a lift car, and further comprises a hoisting system, a braking systemand an anti-falling emergency stop device which are connected with the lift car; the braking system comprises two vertically-arranged braking cylinders; the lift car is connected to the braking cylinders in a sleeved mode and can move up and down along the braking cylinders; braking wheel cylinders embedded with the braking cylinders are arranged at the positions where the top and the bottom of the lift car are connected with the braking cylinders in a sleeved mode; and the braking system further comprises braking elements arranged in the braking wheel cylinders, and the lift car achieves braking through friction force of the braking elements on the braking cylinders. Accidental sudden falling is prevented through lifting of the hoisting system, stopping starting and speed regulation of the braking system and the anti-falling emergency stop device, ascending and descending of personnel can be rapidly achieved, the efficiency problem and the safety problem caused by the inconvenience of getting on and off the tower crane are solved, and operation safety is guaranteed while rapid operation is achieved. The device is simple to operate, high in safety coefficient, convenient, quick, time-saving and labor-saving, and the working efficiency of the tower crane can be improved.
本发明提供一种用于塔吊载人的爬升装置,包括塔吊塔身和轿厢,还包括与轿厢连接的起重系统、制动系统和防坠急停装置,所述制动系统包括两根竖直布置的制动圆柱,所述轿厢套接于制动圆柱且可沿制动圆柱上下运动,所述轿厢顶部和底部与制动圆柱套接处设置有嵌套制动圆柱的制动轮缸,所述制动系统还包括设置于制动轮缸内的制动元件,所述轿厢通过制动元件对制动圆柱的摩擦力实现制动。通过起重系统升降,制动系统停止启动及调速,防坠急停装置防止意外急坠,可快速实现人员上升及降落,克服了因上下塔吊不便带来的效率问题及安全问题,在快速运行的同时保证了运行安全。本发明操作简单,安全系数高,方便快捷,省时省力,可提升塔吊工作效率。
