Description

Technical Field

[0001] The utility model relates to the technical field of helicopter mooring, in particular to an auxiliary device for disassembling and assembling a helicopter mooring rope. Background Art

[0002] The helicopter rotor is an important part of the helicopter and is located above the helicopter. The rotor is the power source for the helicopter to take off and move forward. It generates upward lift through rotation to balance gravity, and generates forward pulling force to overcome air resistance, allowing the helicopter to fly. When a helicopter is parked on the ground, in extremely windy weather, the helicopter rotor will swing up and down continuously due to the wind. If the swing amplitude is too large, it will cause damage to the internal structure of the rotor. In order to prevent extreme windy weather from causing damage to the helicopter rotor, the staff will generally tether the parked helicopter. The tethering is generally done by the staff using a tethering rod to connect the end of the tethering rope with a pin to the pin hole on the helicopter rotor, and the other end is connected to the helicopter fuselage.

[0003] When the existing mooring rod needs to connect a mooring rope with a high height to the rotor, the mooring rod is too long and will swing during use, making it impossible to quickly and accurately put the latch into the latch hole, which is time-consuming and labor-intensive and inconvenient to use.

[0004] Therefore, those skilled in the art provide an auxiliary device for disassembling and assembling a helicopter mooring rope to solve the problems raised in the above background technology. Utility Model Content

[0023] The bottom plate 3 is internally rotatably connected to a driving gear 10, and the bottom plate 3 is also slidably connected to two tooth plates 11, which are respectively engaged with the driving gear 10 from both sides. The upper end of the bottom plate 3 is provided with two sliding grooves 13, and the upper ends of the two tooth plates 11 are fixedly connected to sliding rods 12, which pass through the sliding grooves 13 and are connected to the bottom of the clamping plate 4. When the driving gear 10 rotates, the clamping plate 4 can be driven to move through the tooth plates 11 and the sliding rods 12, so as to clamp and fix the latch, which is convenient for disassembly and assembly.

[0024] The first connecting rod 1 is rotatably connected to a telescopic rod 9, and the length of the telescopic rod 9 can be adjusted by being pulled by an external force.
