Embodiment
A kind of described boom hoisting for preventing that zinc coat from damaging includes two locking units, and the locking list described in two
It is connected between member by steel wire rope.
As shown in Figures 1 to 4, described locking unit includes inner ring 1 and outer ring 2, and is provided with described outer ring 2 outstanding
Ear 21.Retainer 3 is provided between described inner ring 1 and outer ring 2, be provided with described retainer 3 two rows be used for accommodate rolling
The pocket hole of kinetoplast 4, and the pocket hole described in each row is distributed uniformly and circumferentially, and rolling element 4 is provided with described pocket hole.
As shown in figure 8, the middle part vertically of the inner surface of described inner ring 1 is provided with bellmouth 13, the bellmouth
13 front end (using the less one end of diameter before, similarly hereinafter) is provided with the first hole 11, and the rear end of the bellmouth 13 is provided with
Two holes 12.The inner surface setting of described bellmouth 13 has some T-shaped chutes 14 vertically, and T-shaped described in several
Chute 14 is along the circumferential direction uniform.As shown in Figure 3 and Figure 4, latch segment 7 is provided with described T-shaped chute 14, and such as Fig. 9 institutes
Show, the outer surface of described latch segment 7 (using close to the side of the inner surface of bellmouth 13 as outside, similarly hereinafter) on be provided with it is described
The T-shaped sliding block 71 that is engaged of T-shaped chute 14.Described latch segment 7 can slide along T-shaped chute 14.
As shown in figure 3, being provided with the first end cap 5 in the first described hole 11, the first described end cap 5 is that section is T-shaped
Rotary structure, and first through hole in the axial direction is provided with the first described end cap 5, after first end cap 5
End is resisted against on the front end face of the latch segment 7.Between the first described end cap 5 and inner ring 1 can by the way of grafting,
Threaded connection can be used, when using being threadedly coupled, less one end of diameter of the first described end cap 5 is provided with outer spiral shell
Line, internal thread is provided with first hole 11.
As shown in figure 3, being provided with the second end cap 6 in the second described hole 12, the second described end cap 6 is that section is T-shaped
Rotary structure, and the second through hole in the axial direction is provided with the second described end cap 6, before second end cap 6
End is resisted against on the rear end face of the latch segment 7.Less one end of diameter of the second described end cap 6 is provided with external screw thread, institute
State in the second hole 12 and be provided with internal thread.
During work, the first end cap 5 positioned at the front end of inner ring 1 is pulled down first, being then set to described locking unit needs
The outside for the tower material to be lifted by crane, then the second end cap of turn 6, makes the second end cap 6 travel forward, and then promotes latch segment 7 forward
Slide, due to bellmouth 13, diameter is smaller more forward, therefore during latch segment 7 moves forward, gradually tightens up, final to embrace
Tight tower material, realize being relatively fixed for inner ring 1 and tower material, then lifted by crane by steel wire rope, during lifting inner ring 1 relative to
Outer ring 2 is rotated, and inner ring 1 is fixed relative to tower material.First end cap 5 is set herein, primarily to when not working, avoids locking
Tight block 7 skids off from inner ring 1, when operating, it is necessary to remove the first end cap 5.
Further, in order to avoid latch segment 7 interferes when travelling forward with described inner ring 1, while do not work
When, the both ends of the latch segment 7 can reliably be fixed, as shown in figure 8, the diameter M in first hole 11 is more than the taper
Ultimate range N between the relative T-shaped chute 14 of the less one end of diameter in hole 13, the first through hole of first end cap 5
Diameter K be less than the bellmouth 13 the less one end of diameter relative T-shaped chute 14 between ultimate range N.It is described
The diameter Q in the second hole 12 is less than the diameter P of one end being relatively large in diameter of the bellmouth 13.
When further, in order to increase work, the contact area between the latch segment 7 and tower material, ensure locking can
By property, as shown in figure 9, the outer surface of the latch segment 7 is and the described taper identical arc surface of bellmouth 13, the locking
The inner surface of block 7 is the arc surface coaxial with the outer surface of the inner ring 1.
Further, described latch segment 7 is made using quality of rubber materials.
Reliably locked when further, in order to ensure work, locking nut is provided with (in figure on the second described end cap 6
It is not shown).
