Sling rotation-stopping steering gear and helicopter

Abstract

The invention belongs to the technical field of slings, and relates to a sling rotation-stopping steering gear and a helicopter. The sling rotation-stopping steering gear is provided with a rigid frame, a gyroscope is mounted in the middle of the frame, the end of the gyroscope is connected with a motor through a coupling, and a storage battery is fixedly mounted on the position, on the outer sideof the motor, of the inner wall of the frame through bolts; the power end of the storage battery is electrically connected with the motor through a waterproof switch mounted on the frame; an upper hoisting ring is movably mounted at the upper end of the frame through an upper bearing, and a lower hoisting ring is movably mounted at the lower end of the frame through a thrust bearing; and oil seals are arranged on the outer sides of the upper bearing and the thrust bearing correspondingly. By introducing the bearings, circumferential sliding fit between slings and a rotation-stopping device isachieved; the transverse motor drives a vertical inertial wheel to rotate, friction force between the rotation-stopping device and the slings is overcome, and stability is improved; and the storage battery provides rotating electric power for the transverse motor, and waterproofness is ensured through a water sealing structure.

Description

technical field [0001] The invention belongs to the technical field of slings, in particular to a sling anti-rotation steering gear and a helicopter. Background technique [0002] At present, when helicopters at home and abroad are carrying out cable hoisting operations, there is a problem that the steel wire ropes of the hoisted personnel will accelerate the rotation under the torsion of the winch rope device, and due to the influence of airflow fluctuations, the torsion of the sling released by the upper rotating shaft is relatively large. Large, the steel wire rope rotates at an accelerated rate under the torsion of the winch rope controller, which leads to instability in the operation process and threatens the safety of the operators. [0003] In summary, the existing problems in the prior art are: when helicopters at home and abroad are carrying out cable hoisting operations, due to the influence of airflow fluctuations, the torsional force of the upper spinning shaft r...

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: when helicopters at home and abroad are carrying out cable hoisting operations, due to the influence of airflow fluctuations, the torsional force of the upper spinning shaft releasing the sling is relatively large, and the torsion force of the personnel in the winch rope arrangement is relatively large. The accelerated rotation of the lower wire rope causes instability in the operation process and threatens the safety of the operators
