The invention relates to an automatic steel wire rope tensioning device for hoisting equipment, which comprises a connecting seat, a crank mechanism and an electronic limiting component, the crank mechanism is mounted on the connecting seat, the rear end of a crank of the crank mechanism is hinged to the connecting seat, the front end of the crank mechanism is in a cantilever state, a heavy hammer is mounted at the front end, downward pressure is applied to the crank by dead weight, and a tensioning pulley is mounted in the middle of the crank. The tensioning device is used for tensioning a steel wire rope when a heavy object is hung on the electric hoist. And the electronic limiting component is arranged on the connecting seat corresponding to the rear end of the crank. A steel wire rope tensioning task during conventional work of the lifting device can be undertaken through the mechanical structure, when the lifting device executes special lifting work or works abnormally, the mechanical structure reaches a limit position to trigger electronic limiting, power can be cut off immediately, shutdown can be performed, an alarm can be given, safety of lifting equipment can be guaranteed, and accidents are prevented.

    本发明涉及一种起重设备的钢丝绳自动张紧装置,包括连接座、曲柄机构、电子限位组件,曲柄机构安装于连接座上,曲柄机构的曲柄后端与连接座铰接,前端呈悬臂状态,且前端上安装重锤,靠自重给曲柄下压力,曲柄中间装有张紧滑轮,用于对电动葫芦吊有重物时钢丝绳的张紧;电子限位组件安状在对应曲柄的后端处的连接座上。本发明通过机械结构可承担起重装置常规工作时的钢丝绳张紧任务,当起重装置在执行特殊起吊工作、或者工作异常时,机械结构到达极限位置触发电子限位,可立即断电停机并报警,可保证起吊设备的安全并防止意外事故的发生。
