Specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in figs 1 to 6, it is a kind of that there is the electric block of breaking rope protecting, including reel 1, suspension hook 4 and fix
Movable pulley 5 on suspension hook 4, the top of the reel 1 are fixedly installed rolling wheel machine 2, and the one side of the reel 1, which is fixed, to be set
Pulley platform sling 3 is equipped with, equalizer pulley 6 is provided in the pulley platform sling 3, steel wire rope passes sequentially through movable pulley 5 and equalizer pulley
6, the both ends of the steel wire rope at the equalizer pulley 6 are fixedly installed the steel wire rope fixture block 8 close to the pulley platform sling 3.
As depicted in figs. 1 and 2, by the fixation steel wire rope fixture block 8 on 6 both ends steel wire rope of equalizer pulley, no matter when which
When one side steel wire rope is broken, corresponding steel wire rope fixture block rises card at parsing davit, ensureing that weight does not fall.This implementation
In example, distance is safely slid downwards in the presence of certain between steel wire rope fixture block 8 and pulley platform sling 3, is ensured during normal use, by
It is rocked in slight, the steel wire rope at equalizer pulley 6 remains able to certain amplitude and slides up and down, so that steel wire rope fixture block
8 installation does not interfere with the normal use of electric block.
The upper end of the steel wire rope fixture block 8 is fixedly connected with elastic compression seat 9, steel wire rope fixture block and parsing davit it
Between add elastic compression seat and reduce impact of the rope cramp to parsing davit, make hanging object steady, avoid weight bounce caused by two
Secondary harm.
In the present embodiment, the steel wire rope fixture block 8 includes two pieces of clamping plates 81 being clamped in outside the steel wire rope, two clamping plates
It is locked between 81 by multigroup bolt 82 and nut 83, is not only simple in structure compact and easy to assembly, can adjusted automatically
Just, functional evolution is high.
The suspension hook 4 includes main hook part 41, and the upper end of 41 openend of main hook part is provided with shaft 42, described
The first segment safety buckle 43 that can be rotated to it is provided in shaft 42, the lower end of the first segment safety buckle 43 is provided with can
The second segment safety buckle 44 to rotate to it, and be provided in the shaft 42 for the first segment safety buckle 43 and second
Section safety buckle 44 provides the torsionspring 46 of elastic force.
By the way that safety buckle is changed to relatively turnable two-part structure, and it is opposite with certain relative position deformation
Amount when having external force to touch or rock by mistake safety buckle is made to rotate to disengaged direction, can make the upper end phase of second segment safety buckle first
It rotates to first segment safety buckle, but its lower end is resisted against the lower end of suspension hook openend always, is in opening and is closed
State, i.e., just start to rotate is reserved location deflection between the two, and safety buckle remains fit-state with suspension hook, only when
Persistently external force is subject to act on, after reserved location deflection is covered between the two, can just make the random first safety buckle phase of the second safety buckle
The shaft of suspension hook upper end is rotated, so as to open safety buckle, greatly improves security performance.
The first segment safety buckle 43 is bending-like, and the section of the second segment safety buckle 44 is U-shaped structure, described first
The bending part of section safety buckle 43 is stretched in second segment safety buckle 44.During rotation, when the top of second segment safety buckle 44
End is turned to when being in contact with the bending part of first segment safety buckle 43, and position deflection between the two is covered, if there is still
There is lasting active force, be in general exactly to be shown to be manual operation, need to open safety buckle really.
One end of the torsionspring 46 is resisted against in the main hook part 41, and the other end is resisted against the first segment safety
On the bending part of button 43, and stretch in second segment safety buckle 44.Without external forces, second segment safety buckle 44 is being turned round
Under the action of turning spring 46, it can ensure that lower end is in close contact always with the opening portion lower end of suspension hook, avoid the occurrence of peace
Full accident.
In conclusion it is provided by the utility model it is a kind of there is the electric block of breaking rope protecting, it is flat using being held on
The steel wire rope fixture block to weigh on the steel wire rope of pulley both ends so that reserved between parsing davit and safely slide downwards distance, when one side steel wire
When rope is broken, steel wire rope fixture block rises card at parsing davit, ensureing that weight does not fall.
