Lower sheave group, includes the lower sheave of downslide wheel carrier and the setting of two horizontal symmetricals, and lower sheave is set on downslide wheel carrier Portion, two inside of downslide wheel carrier middle and lower part are equipped with two pairs of lower clump weights.
Further, upper clump weight is located at below top sheave, is fixedly connected with downslide wheel carrier by bolt;Lower clump weight is located at The side-lower of lower sheave, the outer rim along lower sheave are cut into arc, are fixedly connected with downslide wheel carrier by welding.
Further, it is equipped with arcuate guide batten along top sheave outer rim below top sheave, is oriented to batten and passes through bolt and downslide Wheel carrier is fixedly connected.
Further, downslide wheel carrier lower part is equipped with suspension hook connecting hole, the hook assembly for connecting handling weight.
Another aspect according to the present utility model provides a kind of derrick crane, which includes before State the lifting hook pulley component described in any one of first aspect.
The utility model has the beneficial effects that:
1, by the way that upper clump weight is arranged on top sheave frame, lower clump weight is set on downslide wheel carrier, handling group can be increased The own wt of part reduces tenesmus amount Lc values so as to tense this section of steel wire rope between travelling jack and main tower;Also may be used This section of steel wire rope between travelling jack and crane arm end is tensed, tenesmus amount Lc ' values are reduced;
2, upper clump weight is connect by bolt with top sheave frame, can be convenient for the dismounting of upper clump weight, be replaced, with adjustable pulley The weight of component effectively increases the versatility and interchangeability of lifting hook pulley component
3, lower clump weight cuts camber along the outer rim of lower sheave, and the guiding batten being arranged below top sheave, can Guiding role is played to steel wire rope when installing steel wire rope on top sheave and lower sheave.

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:
By the way that upper clump weight is arranged on top sheave frame, lower clump weight is set on downslide wheel carrier, handling component can be increased Own wt reduce tenesmus amount Lc values so as to tense this section of steel wire rope between travelling jack and main tower;Also it can draw Tightly this section of steel wire rope between travelling jack and crane arm end reduces tenesmus amount Lc ' values;Existing derrick crane is in lifting When arm lengths are 70m, using the lifting hook pulley component in the utility model, tenesmus amount can reduce 20% ~ 30%, can effectively reduce The case where generating interference between the steel wire rope of difference derrick crane in the operation of multimachine group, reduces construction safety risk.
For the technique effect of the utility model is better achieved, it is further preferable that upper clump weight is located at below top sheave, lead to Bolt is crossed to be fixedly connected with downslide wheel carrier;Lower clump weight is located at the side-lower of lower sheave, and the outer rim along lower sheave is cut into arc, It is fixedly connected with downslide wheel carrier by welding;It is equipped with arcuate guide batten along top sheave outer rim below top sheave, it is logical to be oriented to batten Bolt is crossed to be fixedly connected with downslide wheel carrier.Upper clump weight is connect by bolt with top sheave frame in the utility model, can be convenient for upper The dismounting of clump weight is replaced, and with the weight of adjustable pulley component, effectively increases versatility and the exchange of lifting hook pulley component Property;Lower clump weight cuts camber along the outer rim of lower sheave, and the guiding batten being arranged below top sheave, can be in top sheave Guiding role is played to steel wire rope with when installing steel wire rope on lower sheave.
Another aspect according to the present utility model provides a kind of derrick crane, which includes before State the lifting hook pulley component described in any one of first aspect.
