Background

The wire rope for operation is generally a wire rope specially used for an operation and control system of a large passenger plane and a transport plane, and is mainly used for controlling the aviation wire rope of equipment such as a rudder, an aileron, an engine, a landing gear, a compass needle corrector and the like of the plane. Because the operating environment of the steel wire rope for operation is special, the steel wire rope has higher performance requirements such as corrosion resistance, tensile resistance and the like compared with the common steel wire rope. The existing steel wire rope is formed by twisting a plurality of steel wires, and in the specific use process, because the steel wire rope needs to provide huge traction force, the steel wire rope is inevitably subjected to friction and collision with the inner wall of a machine or is extruded by external force, and then the steel wire rope is damaged. Because the steel wire rope is formed by twisting a plurality of steel wires, as long as one steel wire is broken, the damage of other steel wires is further accelerated, and finally the whole steel wire rope is broken. Therefore, it is particularly important to protect the wire rope, and a new type of wire rope for operation is proposed to solve the above drawbacks.

the utility model provides a novel wire rope for control, from interior to including sinle silk, elastic protection cover, outer jacket, anti extrusion layer and wearing layer outward in proper order, the internal perisporium on anti extrusion layer evenly is provided with has elastic spacing swell, spacing swell all with the outer wall laminating of outer jacket, the internal perisporium of outer jacket evenly is provided with the stop collar that extends along outer jacket axis direction, the stop collar comprises two arc sheet structure, and the inside of stop collar has all been alternate the strand wire rope.

Preferably, the elastic protection sleeve comprises an inner protection layer and an outer protection layer sleeved outside the inner protection layer, elastic members with elasticity are uniformly distributed between the inner protection layer and the outer protection layer, and two ends of each elastic member are respectively connected with the inner protection layer and the outer protection layer.

Preferably, the steel wire strand rope comprises a glass fiber layer, a mica fireproof layer and steel wires in sequence from outside to inside, the number of the steel wires is a plurality, and the steel wires are mutually twisted.

Preferably, the wire core is composed of a plurality of strands of mutually twisted nylon ropes and a braided rope sleeve sleeved outside the nylon ropes.

Compared with the prior art, the utility model provides a novel wire rope for control possesses following beneficial effect:

1. the steel wire rope comprises the anti-extrusion layer, the wear-resistant layer and the elastic protective sleeve, so that the anti-extrusion and anti-collision performance of the steel wire rope is enhanced, and the service life of the steel wire rope is prolonged;

2. the utility model provides a stranded steel wire strand all runs through inside the stop collar, compares the twist in the conventional art and forms, the utility model provides a stranded steel wire strand can conveniently be changed after taking place to damage, is unlikely to make whole wire rope scrap.
