Description

Wire rope shock absorber with stopper

technical field

The utility model belongs to the technical field of machinery, in particular to a steel wire rope shock absorber with a limiter, which is used for vibration reduction, noise reduction and impact isolation of various power machines and working machines.

Background technique

There are many types and forms of wire rope shock absorbers in the prior art, but none of them have stoppers. When the system has certain requirements for the maximum displacement of the vibration-isolated object, it is often necessary to install a separate stopper. The additional limiter complicates the damping system. In some occasions where the space is narrow, it is often impossible to install a separate limiter, so that the application of the shock absorber is limited to a certain extent.

Utility model content

Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a wire rope shock absorber with a limiter, which installs the limiter in the shock absorber so that the two can be combined into one First, it not only simplifies the layout of the vibration damping system, but also can be applied to occasions with narrow spaces.

The technical scheme of the utility model is: the steel wire rope shock absorber with its own limiter is the same as the shock absorber in the prior art, and the steel wire rope is wound in a spiral shape and fixed between the upper splint and the lower splint. The special feature is: there is a through hole in the middle of the upper splint and the lower splint, and at least one elastic element and a limit element that can limit the maximum displacement of the endless steel wire rope are sleeved on the limit screw that passes through the through hole. limit structure. The position-limiting structure is arranged between the upper and lower splints, and at the surface of the equipment rack connected with the upper splint, or at the surface of the base connected with the lower splint. The elastic element in the position-limiting structure is a butterfly spring or a helical spring. The limiting elements that cooperate with the elastic elements in the limiting structure are limiting sleeves, limiting nuts, upper and lower splints of shock absorbers, equipment racks or bases. One end of the limiting screw passes through the upper splint to connect with the frame of the vibration-isolated equipment, and the other end passes through the lower splint to connect with the base.

The utility model has the advantages of reasonable design, simple structure and easy implementation. It integrates the wire rope shock absorber and the limiter, simplifies the structure of the shock absorber system, adapts to the needs of various conditions, and broadens the use of the steel wire rope shock absorber. .

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail. As shown in accompanying drawing 1,2,3,4, described wire rope shock absorber is simple in structure, and it is made up of the helically wound steel wire rope 5 that upper splint 3 and lower splint 2 fix. As far as the shock absorber itself is concerned, it does not include the equipment rack 4 and base 1 shown in the illustration. The characteristic of the shock absorber is that it must be fixed between the base 1 and the frame 4 of the vibration-isolated equipment when used, so the utility model also uses this feature to complete the limit function. In the illustration, the base 1 and Rack 4 of the vibration-isolated equipment is shown. In Fig. 1, two limit elastic element butterfly springs 8 are sleeved on the limit screw 6, one of which is arranged between the vibration-isolated equipment frame 4 and the nut 7, and the other is between the upper splint 3 and the lower splint 2, they together with the sleeve or nut 12 form a limit mechanism. When the vibration-isolated (or shock-isolated) equipment produces a displacement that affects the normal operation of the equipment under external force excitation, the upper splint 3 fastened together with the vibration-isolated (or shock-isolated) equipment is in contact with the limit screw 6 , thereby limiting the displacement of the upper splint to achieve the purpose of spacing (the rest are the same, and will not be described in detail). In accompanying drawing 2, three limit elastic element disc springs 8 are arranged, one is arranged between the equipment frame 4 and the nut 7, and the other two are arranged between the lower clamping plate 2 and the sleeve or nut 12, and the upper clamping plate 3 Together, they form a limit mechanism. Two butterfly springs 8 are arranged in FIG. 3 , one is arranged between the equipment frame 4 and the nut 7 , and the other is arranged on the lower splint 2 . Fig. 4 has shown two belleville springs 8 and a helical spring 14, and a helical spring 8 is arranged between the equipment frame 4 and the nut 7, and another is arranged between the base 1 and the nut 7, and the helical spring 14 is arranged between the upper and lower splints 3, 2, and they form a position-limiting structure together. In Fig. 1-3, the upper end of the limit screw 6 is fixed with a nut 7, and two nuts 7 are used for locking; the lower end of the limit screw 6 is threadedly connected with the base. And the upper and lower ends of the limit screw 6 among Fig. 4 all adopt nut 7 to fix. The illustrations are only for illustration, not all protection contents of the present utility model. The position-limiting structure of the utility model can be limited in three mutually perpendicular directions of the XYZ axes, and the position-limiting amount in the vertical direction is adjustable on site.
