Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
This utility model one buffering suspension hook, its structure is as it is shown in figure 1, include curved suspension ring 1, the two of suspension ring 1
End is fixed on horizontally disposed cover plate 2 by slotted nut 3 respectively, and the underface of cover plate 2 is arranged with spring lower seat 6 in parallel,
Cover plate 2 is connected with spring lower seat 6 by four pull rod studs 12, is provided with buffer cell between cover plate 2 and spring lower seat 6, and
Buffer cell is connected seat 10 through spring lower seat 6 and connects with suspension hook, and suspension hook connects the lower end connection of seat 10 suspension hook 9.
The upper end of every pull rod stud 12 is all passed through nut 11 and is fixed with cover plate 2, and the lower end of every pull rod stud 12 is the most all
Fixed with spring lower seat 6 by nut 11.
Buffer cell, as it is shown in figure 1, include suspension rod 15, suspension rod 15 by boom tip and bar portion through connecting and composing；Boom tip
Being nested in together with the upper semisection in bar portion in the inner chamber of guide holder 14, the top of guide holder 14 is opened wide and is provided with a circle annular table
Face, the bottom center of guide holder 14 is provided with through hole, and the middle part in bar portion makes the lower semisection in bar portion be positioned at guide holder 14 through through hole
Outward, the upper semisection in bar portion is placed in a little lift heavy buffer spring 4, and the upper end of little lift heavy buffer spring 4 contacts with boom tip,
The lower end of little lift heavy buffer spring 4 contacts with guide holder 14 intracavity bottom；The lower semisection in bar portion is placed in a secondary spring 5,
And the upper end of secondary spring 5 contacts with the bottom of guide holder 14, the lower end of secondary spring 5 contacts with spring lower seat 6；Guide holder 14
Being placed in a main spring 13 together with suspension rod 15, the upper end of main spring 13 is supported in the circular table bottom of guide holder 14,
The lower end of main spring 13 contacts with spring lower seat 6；The bottom in bar portion is connected seat 10 through spring lower seat 6 and connects with suspension hook.
Having external screw thread outside bottom, suspension rod 15 bar portion, suspension hook is provided with screwed hole in connecting seat 10, arranges in screwed hole
There is the female thread coordinated with bar portion bottom external screw thread, make the bottom, bar portion of suspension rod 15 can be connected the screw thread in seat 10 with suspension hook
Hole threaded engagement.
It is connected with suspension hook 9 as in figure 2 it is shown, suspension hook connects seat 10 by hook assembly check pin 7 and suspension hook pin assemblies 8.
This utility model one buffering suspension hook, its operation principle is specific as follows:
Suspension ring 1 are connected with crane gear, make suspension hook 9 catch on lifting thing；
If slinging matter weight is lighter:
Gravity under suspension hook 9 only makes suspension rod 15 move downward, the least lift heavy buffer spring 4 pressurized, to wink during lifting
Between inertia force produce cushioning effect；
If lifting thing is heavier:
Gravity on suspension hook 9 first makes suspension rod 15 downwards, and the least lift heavy buffer spring 4 pressurized, suspension rod 15 continues to transport downwards
Move until little lift heavy buffer spring 4 does not continues to be compressed when boom tip touches the circular table at guide holder 14 top；Now
The outside of guide holder 14 presses to main spring 13 and secondary spring 5 and is allowed to compress, thus to moment inertia force during hoisting heavy
Obtain cushioning effect.
This utility model one buffering suspension hook is designed as 5 tons, and external 5 tons of suspension hooks are not have when lifting by crane less lifting thing
Buffering, its main cause be spring be all to design by 5 tons, buffering suspension hook of the present utility model even the weight of lifting only
Having 0.1 ton, also have good buffering effect, it main reason is that it is internally provided with little lift heavy buffer spring 4；It addition, make
During with unit maximum lift heavy between 4.5 tons to 5 tons, can take down secondary spring 5, be user-friendly to, this is also an advantage over state
The bright spot of outer like product.
This utility model one buffering suspension hook, the problem of buffering effect difference when solving big suspension hook lifting lower weight.
