Specific embodiment
As shown in Figure 1, a kind of connection structure of the movable pulley pin shaft of headstock gear, dynamic on two platform slings 1 including being mounted on
Pulley blocks 2 and gate lifting eye 3, the lower end of platform sling 1 are equipped with lifting hole(eyelet), and it further includes two pin shafts 4 that gate lifting eye 3, which is equipped with earhole,
In a pin shaft 4 also cross be located at the same side platform sling 1 on lifting hole(eyelet) and gate lifting eye 3 earhole, another pin shaft 4
The earhole of the lifting hole(eyelet) and gate lifting eye 3 that are placed through on the platform sling 1 of the other side.
By setting two pin shafts 4 for traditional whole pin shaft, the weight of single pin shaft is reduced, is hung for medium-sized
Tool does not need in addition to add shaft crossing device can be realized and wears axis, during wearing axis, can two pin shafts 4 wear axis behaviour simultaneously
Make, the balance of movable pulley can be realized, do not need to add counterweight, save material；Meanwhile pin shaft wear axis operation when, relative to
Pin shaft wears wheelbase from reduction also cross two platform slings, and shaft efficiency is worn in raising, and axis difficulty is worn in reduction；Compared to original single pins
Axis stress, double joint pin shaft stress, can reduce the stress of pin shaft, therefore pin shaft is lighter.
