The invention belongs to the technical field of tower cranes, and particularly relates to a tower crane with a steel wire rope detection system, which comprises a cockpit, a cross beam, a balancing weight, a walking platform and a steel wire rope. A steel wire rope is pressed by a lower pressing area on an installation frame and an upper pressing area on a sliding frame body through an electric push rod, the steel wire rope drives a detection module to move together, in the state, scrapers on an upper installation sliding block and a lower installation sliding block make contact with the steel wire rope, and a second sensor is close to the steel wire rope but does not make contact with the steel wire rope. The upper installation sliding block and the lower installation sliding block slide on the sliding frame and the installation frame in a reciprocating mode to scrape sundries on the steel wire rope in a reciprocating mode, and meanwhile the second sensor detects reciprocating of the steel wire rope to confirm whether the magnetic field of the steel wire rope changes or not. If yes, the tower crane is controlled to stop working; if the magnetic field is not abnormal, the electric push rod is controlled to restore the sliding frame body to the initial state.
本发明属于塔吊技术领域,尤其涉及一种塔吊带钢丝绳检测系统的起重机,它包括驾驶舱、横梁、配重块、行走平台、钢丝绳,在使用过程中,当第二传感器检验到钢丝绳上磁场的变化后,通过电动推杆使得安装架上的下压紧区域和滑动架体上的上压紧区域将钢丝绳压紧,钢丝绳带动检测模块一起运动,而且此状态下,上安装滑块和下安装滑块上的刮板接触钢丝绳,第二传感器靠近钢丝绳但未接触钢丝绳;上安装滑块和下安装滑块在滑动架和安装架上往复滑动对钢丝绳上的杂物起到往复刮除作用,同时第二传感器对钢丝绳往复进行检测以确认钢丝绳的磁场是否变化。若确实有变化则控制塔吊停止工作;若磁场没有异常则控制电动推杆使得滑动架体恢复到初始状态。
