The invention discloses an automatic adjusting system of a safety lifting device. The automatic adjusting system comprises a lifting mechanism and a safety mechanism. The lifting mechanism comprises a lifting arm, a hinge and a lifting rod; the lifting arms are divided into a long lifting arm and a short lifting arm in proportion; the long lifting arm is connected with the short lifting arm through the hinge; the safety mechanism is connected with the short lifting arm through the lifting rod; when interference resistance is encountered in the lifting process, the long lifting arm and the short lifting arm overcome resistance torque through the hinge to automatically adjust the needed angle to act on the lifting rod, and therefore the safety mechanism is lifted. The structure of the lifting arm is optimized, unsmooth interference lifting caused by abnormal lifting in the action process of lifting the safety tongs is avoided, safe and stable lifting is promoted, and safe braking and resetting of the safety tongs are guaranteed; the device is compact in structure, high in stability and convenient to mount.

    本发明公开了一种安全提拉装置自动调整系统,包括提拉机构和安全机构;所述提拉机构包括提拉臂、铰链和提拉杆;所述提拉臂按比例分成长提拉臂和短提拉臂;所述长提拉臂与所述短提拉臂之间通过所述铰链链接;所述安全机构通过所述提拉杆与所述短提拉臂连接;当提拉过程中遇到干涉阻力,所述长提拉臂与所述短提拉臂之间通过所述铰链克服阻力力矩自动调整所需角度作用于所述提拉杆从而提拉所述安全机构。本发明优化提拉臂结构,避免提拉安全钳动作过程中的非正常提拉导致的干涉提拉不顺畅,促使安全稳定提拉,保证安全钳的安全制动及复位;本发明结构紧凑、稳定性高并且安装方便。
