Abstract
The invention relates to a lifting hook buffering device. The lifting hook buffering device comprises a spring and a sliding block. The lifting hook buffering device is characterized in that a ring (2) is arranged at the upper end of a lifting hook (1); a hole (3) is formed in the upper part of the ring (2); the spring (4) is mounted in the hole (3); a rectangular space (5) is formed in the upper part in the ring (2); the sliding block (6) is mounted in the space; an arc-shaped groove (8) is formed in the lower end of the sliding block; clamping blocks (7) are mounted on two sides of the sliding block. According to the lifting hook buffering device, the deficiency that the bearing of the existing lifting hook suddenly changes in a lifting or detaching process because a steel wire rope and a lifting hook ring of the existing lifting hook are directly connected is overcome; the lifting hook buffering device has lots of advantages of simple structure and production process, low cost and remarkable buffer effect and is convenient to mount and use.
Description
Technical field
The present invention relates to mechanical field, the shock absorber more precisely on a kind of crane, driving load hook.
Background technology
Load hook, at machinery, handling industry uses more extensive, crane, driving has, current suspension hook, steel rope is directly connected with suspension hook ring, either large or small gap is there is between rope and ring, crane is when lifting by crane or unload, suspension hook load-bearing can produce sudden change, therefore, operative employee must gently lift by crane or put down, but the most skilled operative employee also keeps away the sudden change of this bearing capacity unavoidable, light then, cause rocking in various degree, heavy then, body can be caused to bend, today of this and exquisite speed, incompatible, although the patent of the shock absorber of existing hoisting crane goes out
Existing, but due to complex structure, difficulty is installed, cost is high, application that so far there are no.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide that a kind of structure is simple, easy to install, with low cost, the significant lifting hook buffering device of buffering effect.
The object of the invention is to adopt following technical measures to realize: a kind of lifting hook buffering device, be made up of spring, slide block, it is characterized in that: in existing suspension hook upper end, be shaped with the ring of circle or ellipse, one hole is arranged at ring Inner top, hole is built with spring, and ring internal upper part has a coffin, and slide block is arranged on space Inner, there is the groove of one one-tenth circular arc slide block lower end, connect for steel rope, fixture block is equipped with on slide block both sides, and anti-limited slip block comes off.
Remarkable result of the present invention: structure and production technology is simple, easy to install, with low cost, buffering effect is remarkable.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Below in conjunction with accompanying drawing, the present invention is further elaborated.
Detailed description of the invention
See figure
,suspension hook 1 upper end, be shaped with circle or oval ring 2, a hole 3 is arranged at ring Inner top, and hole is built with spring 4, and ring internal upper part has a coffin 5, and slide block 6 is arranged on space Inner, and there is the groove 8 of one one-tenth circular arc slide block lower end, and fixture block 7 is equipped with on slide block both sides.
Claims (2)
1. a lifting hook buffering device, be made up of spring, slide block, it is characterized in that: suspension hook is upper end (1), be shaped with ring (2), (3) ring Inner top have a hole, and hole built with spring (4), (5) ring internal upper part has a coffin, (6) slide block is arranged on space Inner, and (8) slide block lower end has the groove of one one-tenth circular arc, and fixture block is equipped with in slide block both sides (7).
