Abstract
The utility model relates to a lifting hook buffering device which comprises a spring and a slider, and is characterized in that the upper end of a lifting hook (1) is provided with a ring (2); the upper part in the ring is provided with a hole (3); the spring (4) is arranged in the hole; the upper part in the ring is also provided with a rectangular space (5); the slider (6) is arranged in the space; the lower end of the slider is provided with a circular arc-shaped groove (8); and both sides of the slider are provided with clamping blocks (7). The lifting hook buffering device overcomes the defects that in the prior lifting hook, the steel wire rope is directly connected with a lifting hook ring, so that weight that the lifting hook bears is suddenly changed when in lifting and unloading, and has the advantages of simple structure and production process, convenient installation and use, low cost, and significant buffering effect.
Description
Technical field
The utility model relates to mechanical field, the shock absorber on a kind of more precisely crane, the driving load hook.
Background technology
Load hook, at machinery, the loading and unloading industry is used more extensive, crane, present suspension hook is arranged in the driving, steel rope and suspension hook ring direct connection, exist either large or small gap between rope and the ring, crane is when lifting or unloading, and suspension hook load-bearing meeting produces sudden change, therefore, the operative employee must gently lift by crane or put down, but the most skilled operative employee also keeps away the sudden change of unavoidable this bearing capacity, gently then, cause rocking in various degree, heavy then, can cause body bending, today of this and exquisite speed, incompatible, though the patent of the shock absorber that existing hoisting crane is used occurs, because complex structure, difficulty is installed, the cost height is not seen application so far.
Summary of the invention,
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, easy to install, with low cost, significant load hook shock absorber of buffering effect is provided.
The purpose of this utility model adopts following technical measures to realize: a kind of load hook shock absorber, form by spring, slide block, it is characterized in that:, be shaped on circular or oval-shaped ring in existing suspension hook upper end, the ring internal upper part has a hole, spring is housed in the hole, and the ring internal upper part has a coffin, and slide block is installed in the space, there is the groove of one one-tenth circular arc the slide block lower end, connect for steel rope, fixture block is equipped with on the slide block both sides, and anti-limited slip block comes off.
Remarkable result of the present utility model: structure and production technology are simple, easy to install, with low cost, buffering effect is remarkable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The specific embodiment
Referring to figure, suspension hook 1 upper end is shaped on circle or oval-shaped ring 2, and the ring internal upper part has a hole 3, and spring 4 is housed in the hole, and the ring internal upper part has a coffin 5, and slide block 6 is installed in the space, and there is the groove 8 of one one-tenth circular arc the slide block lower end, and fixture block 7 is equipped with on the slide block both sides.
Claims (2)
1. load hook shock absorber, form by spring, slide block, it is characterized in that: suspension hook (1) upper end, be shaped on ring (2), a hole (3) is arranged at ring Inner top, and spring (4) is housed in the hole, the ring internal upper part has a coffin (5), slide block (6) is installed in space Inner, and there is the groove (8) of one one-tenth circular arc the slide block lower end, and fixture block (7) is equipped with on the slide block both sides.
2. by the described load hook shock absorber of claim 1, it is characterized in that: the shape of ring (2) is circular or oval.
