The invention discloses an unpowered automatic hook grabbing and unloading lifting appliance and a lifting frame. The lifting appliance comprises a lifting sliding block assembly, an unpowered lifting hook and a self-locking guide mechanism, the unpowered lifting hook comprises a first rotating shaft, an inner connecting rod, an outer connecting rod, an inner claw, an outer claw and a second rotating shaft; a positioning balancing weight is mounted on the second rotating shaft; a self-locking hook is rotationally arranged on the first rotating shaft, a hook part of the self-locking hook is clamped on the second rotating shaft, and the side edge of the hook part is rotationally connected with the bottom of the self-locking guide mechanism through a traction assembly. According to the self-locking hoisting device, firstly, a hoisting ladle is pressed through a positioning balancing weight to enable a rope to protrude, when a self-locking guide mechanism is located at a limiting position and a hoisting sliding block assembly moves to an upper limit position from the lower portion, a traction assembly drives a self-locking hook to be disengaged from a second rotating shaft, and an inner claw and an outer claw achieve the hooking action; when the self-locking guide mechanism is located at the limiting position and the lifting sliding block assembly moves downwards from the upper limit position, the traction assembly drives the self-locking hook to hook the second rotating shaft, and the inner claw and the outer claw achieve the hook unloading action. In the whole process, automatic hook grabbing and unloading are achieved without manual work or other external force, and therefore efficiency is improved, and cost is saved.

    一种无动力自动抓钩卸钩吊具及吊架,该吊具包括起吊滑块组件,无动力吊钩,以及自锁导向机构;无动力吊钩包括第一转轴,内连杆,外连杆,内爪,外爪,以及第二转轴;第二转轴上安装有定位配重块;第一转轴上转动设有自锁挂钩,自锁挂钩的钩部卡在第二转轴上,且钩部的侧边通过牵引组件与自锁导向机构的底部转动连接。本发明中,先通过定位配重块将吊包压住使得绳索凸起,当自锁导向机构处于限定位置,且起吊滑块组件由下运动至上限位置时,牵引组件带动自锁挂钩从第二转轴上脱离,内爪和外爪实现抓钩动作;当自锁导向机构处于限定位置,且起吊滑块组件由上限位置往下运动时,牵引组件带动自锁挂钩勾住第二转轴,内爪和外爪实现卸钩动作。整个过程,无需人工或其它外力而实现自动抓钩卸钩,从而提高效率和节约成本。
