Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
The first aspect of the utility model provides a kind of lifting hook pulley component, including top sheave group and lower sheave group, and two
It is connected using axis pin between person：Top sheave group, including top sheave frame 11 and top sheave 12, top sheave 12 are set on top sheave frame 11
Portion, 11 lower part of top sheave frame, two outside are equipped with a pair of upper clump weight 13；Lower sheave group, including downslide wheel carrier 21 and two levels it is right
The lower sheave 22 of setting, lower sheave 22 is claimed to be set to 21 top of downslide wheel carrier, 21 middle and lower part of downslide wheel carrier, two inside is equipped under two pairs
Clump weight 23；21 lower part of downslide wheel carrier is equipped with suspension hook connecting hole 24, the hook assembly for connecting handling weight.
Winding path of the steel wire rope on lifting hook pulley component is as shown in Figure 6, and the steel wire rope of crane arm end point is through hanging
Transport after the directive wheel on trolley is oriented to along No. 1 direction, then bypassed below two lower sheaves, then along No. 2 directions, then around
The fixed pulley crossed on travelling jack then passes around top sheave then along No. 3 directions, then along No. 4 directions, then passes around
Another fixed pulley on travelling jack, then through on travelling jack another directive wheel be oriented to after, further around crossed main tower,
Guider connection on pinnacle of a pagoda is located at the hoist engine on counter-jib.In this way, the retractable cable by hoist engine operates, you can realize
The elevating movement of pulley assembly, and such winding mode can be such that steel wire rope bears to be the 1/4 of handling weight, effectively extend steel wire rope
Service life.
The operation principle of the utility model is as follows：
