The present invention relates to a shock absorber using a wire rope made of a plurality of thin wires and having a bending elasticity, and more particularly, the wire rope is configured in a coil shape, but is configured to be generally annular, and thus 360 ° as well as up and down directions.

The wire rope buffer is a mechanism that absorbs shock and vibration by using the bending elasticity of the wire rope by winding the wire rope in a coil shape and fixing the upper part with the upper clamp and the lower part with the lower clamp. Wire ropes made by twisting dozens of thin wires are flexible to absorb shocks and vibrations. Such wire rope buffers are widely used for the buffering of various industrial machines such as communication equipment, medical equipment, and sensitive electronic equipment.

The conventional wire rope buffer is a wire rope wound in a coil shape as shown in Figure 1, the upper clamp 10 for mounting the upper end of the wire rope 1, and the lower end of the wire rope (1) It consists of a lower clamp 10 'for mounting.

The upper clamp 10 has an outer portion 10a and an inner portion 10b coupled to each other by a hexagonal groove screw 11 and a wire rope 1 is mounted between the outer portion 10a and the inner portion 10b. The lower clamp 10 'has an outer portion 10'a and an inner portion 10'b coupled to each other by a hexagonal groove screw and a wire rope 1 between the outer portion 10'a and the inner portion 10'b. Is mounted. The upper clamp 10 is formed with a spiral groove 12 for connecting to the upper machine, and the lower clamp 10 'is formed with a groove for connecting to the lower mount.

Such wire rope shock absorber is installed in the lower part of the industrial machine, for example, to prevent shock and vibration from being transmitted to the floor.

However, since the wire rope shock absorber has a straight structure, the elasticity in the winding direction of the wire rope 1, that is, in the longitudinal direction of the clamp and in the perpendicular direction thereof is different from each other. Therefore, there is a part that can not effectively absorb the shock and vibration in the transverse direction depending on the characteristics of the support object installed on the top of the wire rope.

In the conventional wire rope buffer, the clamps 10 and 10 'attaching the upper and lower ends of the wire rope 1 are coupled to the outer 10a, 10'a and the inner 10b, 10'b, respectively. The wire rope 1 is attached. Therefore, there is a problem in that the structure of the clamp is complicated and the manufacturing process is complicated, such as the combination of the outer (10a) (10 'a) and the inner (10b) (10' b) with a plurality of hexagonal groove screws (11).

The present invention is to solve the problems of the prior art, an object of the present invention is to provide a wire rope that absorbs shock and vibration more effectively by having a uniform degree of absorption ability of any angle of the transverse impact and vibration. To provide a buffer used.

Another object of the present invention is to provide a shock absorber using a wire rope that shortens the manufacturing time and lowers the manufacturing cost by simplifying the structure and manufacturing process of the clamp fixing the top and bottom of the wire rope.

The buffer using the wire rope of the present invention for achieving the above object is formed with a plurality of through holes through which the wire rope is formed at a predetermined angle in the transverse direction and the upper portion of the annular conical groove is formed on the upper surface of each through hole portion A plurality of through holes through which clamps and wire ropes pass are formed at regular angles in the transverse direction, and an annular lower clamp having a conical groove formed on a lower surface of each of the through hole portions, and a horizontal through of the upper clamp and the lower clamp. It is characterized in that it comprises a wire rope which is sequentially penetrated through the ball to form an annular coil shape and punched into the conical groove of the upper clamp and the conical groove of the lower clamp after being inserted into the through hole.

The shock absorber using the wire rope of the present invention is also characterized in that the upper clamp is formed with a spiral groove for fixing a support object on the upper side, and the lower clamp is formed with a screw hole used when being fixed to the lower mount. .

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.
