Cable-driven wire rope connection device and its connection with astronomical telescope feed cabin

Abstract

The invention discloses a cable-drive steel wire rope connecting device which comprises a Y-shaped piece, a check ring, a knuckle bearing, a pin roll I, a spacer sleeve, a pin roll II, a protective plate, a tension sensor, a pin roll III, a steel wire tope connector, a steel wire rope and a connecting support. The Y-shaped piece is connected with the steel wire rope connector through the tension sensor, the connecting support is connected with the Y-shaped piece through the knuckle bearing and the pin roll I, and the connecting base is connected with a cable drive component. The cable-drive steel wire rope connecting device has the advantages that stress conditions of all steel wire ropes can be obtained timely, and a feed source cabin can be controlled more accurately; on the condition that the tension sensor is fractured, the protective plate can maintain connection of the connecting device, support the cable drive component, and prevent the cable drive component from being damaged; the connecting device has no additional bending moment, the stress condition is clear, and safety and reliability are high; the difficulty of control over the multi-freedom-degree motion of the feed source cabin is reduced; the knuckle bearing is used for connecting the connecting support and the Y-shaped piece, so that additional bending moment is prevented from being applied to the Y-shaped piece, stress intensity of the Y-shaped piece is reduced, and reliability of driving a feed source cabinet is improved.

Description

technical field [0001] The invention belongs to a steel wire rope connection device for cable machinery, in particular to an astronomical telescope cable driving steel wire rope connection mechanism. Background technique [0002] The signal receiving device of the telescope used in the astronomical field is the feed cabin. The feed cabin is arranged with multiple degrees of freedom and driven by several wire ropes. In the prior art, the connection method between the wire rope and the feed cabin is mainly a combination of a pin shaft and a rope clamp. Install. Its disadvantages are: [0003] Without a wire rope tension detection device, the tension of the wire rope cannot be accurately detected, so that the tension of the wire rope cannot be accurately controlled, and it is easy to cause uneven loads on multiple wire ropes, thereby affecting the life of the wire rope and even breaking the wire rope; [0004] In addition, in the existing steel wire rope joint form, the bendi...

Problems solved by technology

[0003] Without a wire rope tension detection device, the tension of the wire rope cannot be accurately detected, so that the tension of the wire rope cannot be accurately controlled, and it is easy to cause uneven loads on multiple wire ropes, thereby affecting the life of the wire rope and even breaking the wire rope;

[0004] In addition, in the existing steel wire rope joint form, the bending moment on the pin bearing is too large, the size of the component is large, and the weight of the mechanism is too large, which affects the rational layout of the mechanism
