(5) DEVICE FOR CABLE TEST

I

The invention relates to a test technique and is intended to simulate the natural conditions of the cable when studying towing processes.

A device for testing cables and models is known, comprising a base, a trolley with a drive and blocks for the cable attached thereto, as well as a mechanism for producing oscillations of the cable l.

However, this device does not recreate all the conditions for testing a cable compared with the natural conditions of operation.

The purpose of the invention is to approximate the conditions for testing a cable to the natural conditions of its operation by providing continuous, multiple repetitive oscillations of a cable.

The goal is achieved by the fact that the device is equipped with a frame hinged on the base and made with guides for the trolley, as well as with a crank mechanism connecting the drive with the trolley, while the mechanism for creating oscillations of the cable includes a crank with the drive connected to frame by means of gi, the ends of which are pivotally attached to the frame and crank, and the connecting rod is made telescopic.

Figure 1 shows a device for testing a cable; figure 2 is the same, side view.

The device includes a base 1, on which a frame 2 with a carriage 3 and an actuator and blocks 5 mounted on a carriage 3 for a cable 6 are hingedly mounted; to create oscillations of the cable, there is a mechanism for creating oscillations 7 and the frame 2 is provided with guides 8 for a trolley, for moving which there is a crank mechanism 9 with a drive, and a mechanism for creating oscillations of a cable in a different plane includes a crank 10 with an actuator that is hinged 11 frame 2, while the connecting rod 12 is made telescopic. The device works as follows. Test cable 6, is filled in blocks 3 and unrolled from the drum or wound on a drum (not shown), imitating the release or the device towed on this cable (models. Simultaneously the cable 6, which is in blocks 5, performs reciprocating movement together with trolley 3 along frame 2, la frame 2 together with trolley 3 performs also rolling movements.The cable 6 communicates oscillations similar to oscillations that occur in the forwarding of the cable and towed models by the incident flow. generating vibrations and the movement mechanism can be isolated and their operation, may be produced in which only vozvratnopostupatelnye or trolley movement along the frame 3 at the frame 2 fixed, or only the oscillating movement of the frame 2 at the fixed carriage 3. The proposed device allows to carry out comprehensive tests

Claims (2)

W cable under conditions close to natural conditions of work. Claim 1. Device for testing a cable, containing a base, a trolley with a drive and attached blocks for a cable, as well as a mechanism for creating oscillations of a cable, so that, in order to approximate the conditions of testing a cable to full-scale conditions his work by providing continuous, repeated vibration of the cable, it is equipped with a frame hinged on the base and made with guides for the trolley, as well as a crank mechanism connecting the drive with the trolley, while the fur The bottom of the oscillation of the cable includes a crank with a drive, connected to the frame by means of a cable, the ends of which are hinged to the frame and the bearing bearing. 2. Device rt. 1, which is the fact that the connecting rod is made telescopic. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 501003, cl.
