Abstract
The utility model relates to a handing apparatus for protecting sleeve of airspeed head, which is a spring perch arranged at the upper end of a long stainless steel pipe; the human hands are to screw left (or screw right) the adjustment screws with the help of a pair of adjustment screws and copper sleeve nuts arranged at the lower end of the stainless steel pipe through a pulley and a pull rope to open (or clamp tight) a jaw of the spring perch arranged at the upper end of the stainless steel pipe so as to extend the length of the human hand, thus enabling the aircrew to safely and conveniently load and unload the pivot cover with standing on the ground.
Description
The utility model relates to a kind of special tool that aircraft airspeed is guaranteed sheath that loads and unloads.
At present; aircraft finishes one day flight; or land to take off next time greater than under two hours the situation; in order to protect pitot, prevent the intrusion of dust storm or foreign matter, by the operating instruction requirement; the technical attendant must load onto pitot protecting sleeve (hereinafter to be referred as the air speed pipe box); thereby, after landing, aircraft loads onto the air speed pipe box, and unloading the air speed pipe box before taking off just becomes a routine operation in the normal aircraft maintenance.As prescribed, loading and unloading air speed pipe box must be handed pitot and be enclosed within the direction that is parallel to the air speed tubular axis and push away or pull out, because pitot is in the height more than 2.5 meters, standing in ground human hand reaches, must operate by means of working stand, because of this operation extremely simple, only because people's height is not enough, all will remove a big ladder just can finish at every turn, really not too convenient, as a result some technical attendant seeks and saves trouble, and operates by the action of some danger, very harmful to aircraft safety, do not meet airworthiness requirement.
The purpose of this utility model just provides the special tool of a kind of aircraft airspeed protection of pipe cover loading and unloading, prolongs the length of staff with it, and the people is stood in just can be convenient without working stand on the ground, safety by the loading and unloading of operating instruction realization to pitot.
The purpose of this utility model is achieved in that the spring perch that is loaded on long stainless steel tube one end is by pulley and stay cord, the other end at stainless steel tube is realized the action that anchor clamps are opened or clamped with hand adjustment joint screw, thereby reaches the pushing degree purpose of prolonged human.
Owing to adopt such scheme, the people is stood in just can be convenient without working stand on the ground, safety by the loading and unloading of operating instruction realization to pitot.
Below in conjunction with accompanying drawing the utility model is further specified.
The folder mouth of 1 anchor clamps among the figure, the spring of 2 anchor clamps, the upper and lower arm of the 3 anchor clamps application of forces, 5 copper sheathings, 6 pulleys, 7 nylon ropes, 8 stainless steel tubes, 9 copper sheathing mothers, 10 governing screw, 11 copper packings.
In Fig. 1, the folder mouth (1) of anchor clamps, the spring of anchor clamps (2), form spring perch with the upper and lower arm of the application of force of anchor clamps (3) and (4), its following force arm (3) is fastening with the upper end of the stainless steel tube (8) of length, one end of nylon rope (7) is fixed on the force arm (4), and by pulley (6), pass the centre hole of governing screw (10) and pad (11), make a call to a big knot at its exit end, save screw (10) advancing or retreating in copper sheathing mother (9) like this in the lower end of stainless steel tube with hand adjustment and just can realize the anchor clamps folder mouthful purpose of opening or clamping.In order to load onto the air speed pipe box, technical attendant's left hand left-handed governing screw of stainless steel tube (8) right hand (10) of holding this special tool on the ground makes and clamps folder and mouthful open, the pitot cover can be sandwiched among the mouth, dextrorotation governing screw (10) is closed up anchor clamps folder mouth, so that clamp the air speed pipe box, holding up stainless steel tube makes its upper end be in the pitot that air speed pipe box in the anchor clamps folder mouthful is parallel to aircraft, set up abreast lightly, with the left-handed governing screw of the right hand (10) anchor clamps folder mouth is opened, unclamp the air speed pipe box, can take this special tool away, finish the operation of dress air speed pipe box.The step of taking off air speed pipe box under the front dump gets final product by the opposite sequence of said procedure, thereby reach the purpose of the pushing degree of prolonged human, the utility model is owing to adopt such scheme, make the people stand on the ground without working stand just operating instruction realization easily and safely to the loading and unloading of pitot.For the length of the length design-calculated stainless steel tube that prolongs staff, can be adjusted according to the type of aircraft.
Claims (1)
1. an aircraft airspeed protection of pipe cover loads and unloads device; it is characterized in that the folder mouth [1] of anchor clamps, spring [2] and the application of force upper arm [3] of anchor clamps and the spring perch that underarm [4] is formed of anchor clamps; its following force arm [3] is fastening with the upper end of stainless steel tube [8] by copper sheathing [5]; one end of nylon rope [7] is fixed on the last force arm [4] of anchor clamps, and the centre hole that passes governing screw [10], copper sheathing mother [9] and pad [11] by pulley [6] is made a call to a big knot at its exit end.
