The invention discloses a special lifting appliance. The special lifting appliance comprises an upper twisting support, a lower clamping jaw locking disc and an anti-rotation inserting plate. And the upper hinged support of the lifting appliance can be connected with a hook head of the MG600t portal crane through a pin shaft. The lower clamping jaw locking disc is rotationally connected to the bottom of the upper twisting support, the lower clamping jaw locking disc is a barrel, a groove is formed in the lower side of the lower clamping jaw locking disc, a protruding protruding block is arranged on the upper portion of the drilling tool, and the protruding block of the drilling tool can penetrate through the groove to enter the lower clamping jaw locking disc to achieve rotary connection. The anti-rotation inserting plate is inserted into the lower clamping jaw locking disc and used for limiting rotation of the drilling tool located in the lower clamping jaw locking disc. Therefore, the hook head of the MG600t portal crane is reliably connected with the drilling tool through the special lifting appliance, the traditional mode of binding and hanging by using a steel wire rope and a shackle is replaced, and the special lifting appliance has the advantages of high safety coefficient, compact structure, convenience in use and long service life.
本发明公开了一种专用吊具，包括上绞支、下卡爪锁紧盘和防旋插板。吊具的上绞支可通过一根销轴与MG600t门式起重机钩头连接。下卡爪锁紧盘转动连接在上绞支的底部，下卡爪锁紧盘为筒体，下卡爪锁紧盘的下侧内部设有凹槽，钻具的上部具有凸起的凸块，钻具的凸块能够穿过凹槽进入所述下卡爪锁紧盘内实现转动连接。防旋插板插设在下卡爪锁紧盘上，用于限定位于所述下卡爪锁紧盘内的所述钻具转动。这样通过一种专用吊具将MG600t门式起重机钩头与钻具实现可靠连接，代替传统用钢丝绳、卸扣绑扎吊挂的方式，具有安全系数高、结构紧凑、使用方便、使用寿命长的诸多优点。
