Abstract
The utility model provides a kind of spring buffer crampon, including branch sleeve, pulley is provided with branch sleeve, branch sleeve bottom is provided with hook, hook is fixed on spring bumper cover, spring is provided between spring bumper cover and branch sleeve bottom, the limiting plate that limited spring cover plate moves up is provided with branch sleeve.The suspension hook can not only provide sufficient intensity, ensure to sling the basic function of object；And spring is also added inside suspension hook, play a part of pulling force and slow down, and there are multiple springs to ensure the resistance to overturning when hanging object is sling.
Description
Technical field
The utility model relates to a kind of technical field of crane equipment, and in particular to a kind of lifting with buffering effect
Suspension hook.
Background technology
In the prior art, known technology is that suspension hook is the indispensable important part of hoisting machinery, at present
The suspension hook used, using integrative-structure, to be rigidly connected, crane is during hoisting heavy, operator's misoperation,
Quickly lift weight, suspension hook can be stressed directly, cause suspension hook stress excessive, influence the life-span of suspension hook, certain safety be present
Hidden danger.Therefore, it is necessary to develop a kind of crane during hoisting heavy, there is provided the device that certain pulling force slows down, ensure work
Cheng Zhiliang.
The content of the invention
The purpose of this utility model, aiming at the deficiency present in prior art, and provide a kind of spring buffer lifting
Suspension hook, the suspension hook can not only provide sufficient intensity, ensure to sling the basic function of object；And spring is also added inside suspension hook,
Play a part of pulling force to slow down, and there are multiple springs to ensure the resistance to overturning when hanging object is sling.
This programme is achieved by the following technical measures：A kind of spring buffer crampon, including branch sleeve, even
Pulley is provided with female connector cylinder, is provided with hook in branch sleeve bottom, is the characteristics of this programme：Hook is fixed on spring bumper cover
On, spring is provided between spring bumper cover and branch sleeve bottom, is provided with what limited spring cover plate moved up in branch sleeve
Limiting plate.
Described pulley is two, and pulley is fixed on branch sleeve by pulley support.
Spring is provided with fixing groove with branch sleeve fixed connection place.Fixing groove is circle, and spring diameter is straight with fixing groove
Footpath is identical.Described spring is four, and four springs are evenly distributed on around hook.
The hook is fixed on spring bumper cover by nut.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due to linking up with top and bullet in this scenario
Spring cover plate is fixed by nut, and the limiting plate fixed in branch sleeve limits the displacement of lateral spring, and limiting plate passes through welding
It is fixed on inside branch sleeve.Transferred force to by hanger bulk on nut, nut transfers force to spring bumper cover lid, passes through
Spring bumper cover lid compression spring, the power of lifting is buffered using the elastic force of spring, by the way of being buffered to hook, reached
The influence vibrated during lifting is offset, so as to avoid suspension hook from occurring significantly rocking, avoids causing potential safety hazard；Described
There are 4 springs between spring bumper cover and branch sleeve, 4 springs, which are uniformly distributed, to be fixed on around hook, and spring is fixed on fixation
In groove, prevent suspension hook is improper from using, in suspension hook dropping process, spring occur upwards or the unexpected displacement to side.This practicality
It is new that there is simple in construction, peace to tear easy to maintenance, the advantages of economizing on resources while effectively suspension hook being avoided to rock open.Thus
It can be seen that the utility model is compared with prior art, there is substantive distinguishing features and progress, its beneficial effect implemented is also aobvious and easy
See.
