Summary of the invention
In the above-mentioned auxiliary device for wing-shaped flap swich, when the anglec of rotation θ of air-foil blade W is positioned at about 90 degree when opening, shown in Fig. 1 (b), the angle that the 1st connecting rod 13 and the 2nd connecting rod are 14 is below 180 degree, the ratio L4/L3 of the distance among the above-mentioned formula M2=M1L4/L3 is big, and it is big to open moment M2.Along with the angle of 14 on the 1st connecting rod 13 and the 2nd connecting rod moves closer to 180 degree, distance is opened moment M2 and is sharply increased than the rapid increase of L4/L3.When the 1st connecting rod 13 and the 2nd connecting rod 14 were in alignment, distance formed the dead point than L4/L3 infinity.
When air-foil blade W is in open mode, sets the value open moment M2 and air-foil blade W is overcome by the closing moment M of deadweight generation keep open mode, and, the operator is overcome open moment M2 and close air-foil blade W easily.
But air-foil blade W is long and thin thickness along the fore-and-aft direction of container, easy deformation.If air-foil blade W deforms or foozle or alignment error, will make both allocations of position deviation that the installation component 41 that is attached at the 2nd connecting rod 14 tops is fixed in air-foil blade W.In addition, the position that the position of the center of rotation w of air-foil blade W, auxiliary device for wing-shaped flap swich are fixed in container also can be because of foozle or alignment error and depart from.
If the installation component 41 on the 2nd connecting rod 14 tops is fixed in the position of air-foil blade W, when promptly the apical position of the 2nd connecting rod 14 departed from respect to the position of the center of rotation w of the center of rotation b of the 1st connecting rod or air-foil blade W, distance L 3 and distance L 4 changed respectively.If the apical position of the 2nd connecting rod 14 departs from a little, then when air-foil blade W was in open mode, the variable quantity of distance L 3 was compared very big with the variable quantity of distance L 4, and distance is also bigger than the variable quantity of L3/L4.Consequently open moment M2 and become big.
If the moment M2 that opens when causing air-foil blade to be opened because of distortion, foozle or the alignment error of air-foil blade W becomes big, then when air-foil blade W opens, air-foil blade W can take place to keep open mode, or the operator is difficult to close the problem of air-foil blade W.
Solve the conception of problem
1) notices: cause in distortion, foozle or alignment error that the apical position of the 2nd connecting rod 14 departs from, opening moment M2 when air-foil blade is opened becomes under the big situation because of air-foil blade W, if increase or shorten the length of the 2nd connecting rod 14, the variable quantity of opening moment M2 the when air-foil blade that can reduce because the distortion of air-foil blade W etc. causes is opened.
For example, air-foil blade is under the open mode, from Fig. 1 (b) as can be known, if the apical position of the 2nd connecting rod 14 to the center of rotation w of air-foil blade W lateral deviation from, the angle of inclination of the 2nd connecting rod 14 can become greatly, distance L 3 and distance L 4 increase respectively.At this moment, will diminish if shorten the angle of inclination of the 2nd connecting rod 14, the 2 connecting rods 14, the recruitment of the recruitment of distance L 3 and distance L 4 can reduce respectively.The variable quantity of opening moment M2 that the reasons such as distortion of air-foil blade W cause can reduce.
On the contrary, if the position on the top of the 2nd connecting rod 14 to a lateral deviation opposite with the center of rotation w side of air-foil blade W from, the angle of inclination of the 2nd connecting rod 14 can diminish, distance L 3 and distance L 4 can reduce respectively.At this moment, if make the 2nd connecting rod 14 elongated, the angle of inclination of the 2nd connecting rod 14 will become greatly, and the reduction of the reduction of distance L 3 and distance L 4 can reduce respectively.The variable quantity of opening moment M2 that the reasons such as distortion of air-foil blade W cause can reduce.
2) when the reasons such as distortion because of air-foil blade W cause the apical position of the 2nd connecting rod 14 to depart from, when the length of increase and decrease the 2nd connecting rod 14, can consider to prepare each how many 2nd different connecting rods of a lot of length, replace the 2nd connecting rod.But, prepare the 2nd different connecting rod of a lot of length in advance, the axle at the 2nd connecting rod two ends is pulled down respectively, in order to replace the 2nd connecting rod, so take time and energy very much.
Therefore, the 2nd link design is become can stretch, can adjust length.
Specifically, the 2nd connecting rod is made of with these two members of member that are linked to the base end side of the 1st connecting rod the member of the tip side that is linked to air-foil blade.On a member, form helical axis, on another member, form screwed hole.Two members screw togather to link by helical axis and screwed hole and are one.When a member during with respect to the rotation of another member, the screw mechanism by helical axis and screwed hole increases and decreases the length of the 2nd connecting rod.Can extend to a direction rotation, can shorten to the other direction rotation.Rotation is during 1 week, and the length of a pitch of increase and decrease screw mechanism during the rotation half cycle, increases and decreases the length of screw mechanism half pitch.Like this, the length of the 2nd connecting rod will obtain simply bit by bit adjusting with small quantity.
After the 2nd connecting rod that can stretch is linked between air-foil blade and the 1st connecting rod, when adjusting length, a member is taken off from air-foil blade or the 1st connecting rod, with respect to another member rotation, after increase or the minimizing length, again this member is linked to air-foil blade or the 1st connecting rod.
3) air-foil blade and auxiliary device for wing-shaped flap swich are installed in container respectively.Therefore, the distance between the center of rotation of the 1st connecting rod of the center of rotation of air-foil blade and auxiliary device for wing-shaped flap swich is easy to generate alignment error.
Therefore, for eliminating alignment error, can expect making air-foil blade to be rotatably mounted in the structure of auxiliary device for wing-shaped flap swich.
