Abstract
The utility model discloses a rope cutting-off device comprising a rope through hole, a cutter and a power device, wherein a rope is connected with an aircraft after the rope through the rope through hole; and the power device is connected with the cutter so as to provide cutting power for the cutter to cut off the rope in the rope through hole. The rope cutting-off device can safely cut off the rope from the aircraft.
Description
Technical field
The utility model relates to rope cutting field, particularly a kind of rope shearing device.
Background technology
At present, in the transmission line construction field, using the exhibition of soaring of aircraft such as helicopter, dirigible, propeller-parachuting, unmanned plane to put rope (for example, the guiding rope) has become normality, and the guiding rope of putting of opening up is generally
Enlightening Nima rope.Enlightening Nima rope toughness is stronger, and universal cutter is difficult to rapid cut-out.Especially let slip in the journey in aircraft exhibition, in case when running into emergency and Di Nima strop and aircraft itself need be broken away from, rapidly the Di Nima rope being cut off is to influence one of key factor that aircraft security flies.
The existing mode of breaking away from mainly contains two kinds.A kind of is that propeller-parachuting is commonly used, utilize spring cutting knife (being similar to chopper) to cut off the guiding rope, but effect is not very desirable, is difficult to guarantee can both cut off at every turn.Because the spring cutting knife adopts preloading spring, retracting spring potential energy principle, can once not cut off if having, need preloading spring mechanism once more when reusing cutting knife, wasted the finite time of getting rid of the aircraft dangerous situation, the potential safety hazard that aircraft aloft flies is not still thoroughly eliminated.
Another kind of mode is that the guiding reel for rope (head) that aircraft is carried falls from aircraft unloading (throwing away).But will increase security risk under this kind mode to ground staff, equipment or other ground things.
The utility model content
One of the purpose of this utility model provides a kind of rope shearing device that can cut rope safely.
Be to provide a kind of rope shearing device to comprise: cable-through hole, cutter, power set according to the technical solution of the utility model; Rope is connected with aircraft by described cable-through hole; Described power set are connected with described cutter, provide cutting power to cut off the rope in the described cable-through hole for described cutter.
The rope shearing device that provides according to the utility model can be with rope safety cut-off from the aircraft.
Description of drawings
Fig. 1 is the structural representation of the rope shearing device that provides of the utility model embodiment;
Fig. 2 is a vertical view of shearing piston.
The specific embodiment
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.As shown in Figure 1, the rope shearing device that the utility model embodiment provides comprises: cable-through hole 6, the power set that are used to cut the cutter 4 of rope and are used for providing cutting power to cutter 4.More than each device be arranged in the cavity of forming by termination 1 and housing 5 of rope shearing device.Rope (can be strop) connects by cable-through hole 6 and aircraft (for example, helicopter, propeller-parachuting etc.).Wherein, cutter 4 is to shear piston or similar substitute.Power set comprise power supply, heating wire 2 and gunpowder 3, and power supply is connected with heating wire 2, and heating wire 2 places gunpowder 3.Wherein, power supply can provide in the following manner: unmanned airborne power supply provides power, during the state of emergency by UAV Flight Control System from trend cutter power supply, control personnel's control to special-purpose cutter power supply by unmanned plane during flying during perhaps non-emergent state.
This rope shearing device operation principle is to utilize the thrust promotion shearing piston of gunpowder to cut off high-strength guiding cord fibers, utilizes the thin portion of the thorough fusing of the moment high temperature fiber of gunpowder simultaneously.Two sending out and usefulness during use, efficient and reliability height can guarantee that in emergency circumstances rope moment breaks away from aircraft, can realize once, the function of instantaneous trip strop.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
Claims (3)
1. a rope shearing device is characterized in that, comprising:
Cable-through hole, cutter and power set; Rope is connected with aircraft by described cable-through hole; Described power set are connected with described cutter, provide cutting power to cut off the rope in the described cable-through hole for described cutter.
2. rope shearing device according to claim 1 is characterized in that, described cutter is to shear piston.
3. rope shearing device according to claim 1 and 2 is characterized in that, described power set comprise:
Power supply, heating wire and gunpowder, power supply is connected with described heating wire, and described heating wire places described gunpowder.
