The most common lifting appliance in a hoisting mechanism of a crane is a lifting hook, but when an object is hung, the object on the lifting hook often falls off, so that safety accidents are easy to happen.
Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model aims to provide an anti-drop's lifting hook for tower crane.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an anti-drop's lifting hook for tower crane, includes pulley holder and lifting hook, the lifting hook includes the connecting rod of fixed connection in the pulley holder bottom, the bottom fixedly connected with sill bar of connecting rod, the vertical ascending gag lever post of sill bar tip fixedly connected with, the spout that runs through its top is seted up to the gag lever post, sliding connection has the locating lever in the spout, the sliding tray that runs through its upper surface is seted up to the sill bar, sliding connection has the butt pole in the sliding tray, the sill bar seted up communicate in the spread groove of spout and sliding tray, sliding connection has the actuating lever in the spread groove, the butt pole the bottom with the tip of actuating lever is the inclined plane of parallel and butt, the bottom of gag lever post with the tip of actuating lever is the inclined plane of parallel and butt.
Through adopting above-mentioned technical scheme, when carrying out the hoist and mount operation, hang into the couple with the lifting rope in, under the effect of lifting rope for the butt joint pole lapse, thereby drive the actuating lever and slide towards the locating lever, thereby drive the locating lever upwards slide, and make its top support tightly in the lower surface of pulley seat, thereby prevent that the lifting rope from taking place to drop, guarantee the stability of hoist and mount operation.
The utility model discloses further set up to: the top end fixed connection of butt joint pole has the butt joint board of level setting, the butt joint pole is located the cover and is equipped with the spring between butt joint board and the sill bar.
Through adopting above-mentioned technical scheme, the lifting rope is hung in the butt plate surface, when carrying out the hoist and mount operation, drives the butt plate decline and makes the spring compressed to drive the locating lever upward movement, accomplish the back when the hoist and mount operation, under the effect of spring elasticity, make butt plate and locating lever reset, in the time of the operation of being convenient for, promote the stability of couple during operation.
The utility model discloses further set up to: and the lower surface of the pulley seat is provided with a positioning groove for the positioning rod to be inserted.
Through adopting above-mentioned technical scheme, when carrying out the hoist and mount operation, locating lever upward movement, in its top inserted the constant head tank, when further preventing that the lifting rope from droing, guarantee the stability of locating lever in the course of the work.
