[specific embodiment]

Further specify the present invention below in conjunction with accompanying drawing.

Quasi double-hinge mechanism can be reduced to three-link mechanism, as shown in Figure 1, because hinge rear axle 10 links to each other with hinge bonnet 11,15, and hinge bonnet 11,15 is fixed on the cabin body 1, easily know the stationkeeping of hinge rear axle 10, hinge front axle 8 is owing to linking to each other with hinge protecgulum 9,14 and moving with gate 4, so the position of hinge front axle 8 is indefinite.Link to each other with hinge connecting rod 9,14 between two hinge axis, establishing the hinge length of connecting rod all is L.Hinge bonnet 11,15 is connected on cabin body 1 or the cabin body flange 2, and length all is L1, and the other end is connected on the hinge rear axle 10.Hinge protecgulum 7,13 1 ends are connected on the gate flange 3, and the other end is connected on the hinge front axle 8, and length all is L2.The design objective of quasi double-hinge gate mechanism is to make the arm of force of whole linkage the shortest, is promptly guaranteeing that hinge protecgulum 7,13L2, hinge connecting rod 9,14L, hinge bonnet 11,15L1 should be the shortest under the prerequisite that the hinge arrangement function realizes.

Under the perfect condition, when gate 4 is closed, the position of supposing hinge protecgulum 7,13, hinge connecting rod 9,14 and hinge bonnet 11,15 concerns as shown in Figure 1, the plane at two hinge axis, 8,10 axis places can not parallel with the axis of cabin body 1 (being α ≠ 0), otherwise hinge bonnet 11,15 and hinge connecting rod 9,14 can " dead point " occur in hinge rear axle 10 cooperation places, and the angle of establishing between the axis of the axis of hinge connecting rod 9,14 and cabin body 1 is α.Suppose hinge rear axle 10 as 360 degree during full rotating shaft, hinge front axle 8 is limited turning cylinder, it is relevant with the ability of regulating two end face of flange that the position of hinge rear axle is determined, suppose that two end face of flange do not fit distance for w, for compensation is not fitted apart from w, the rotational angle of hinge rear axle is β, can get following geometric relationship from figure:

$s=2L\sin \left(\frac{\mathrm{\β}}{2}\right)\·\cos (\frac{\mathrm{\β}}{2}+\mathrm{\α})$ Formula 1

S is that hinge protecgulum 7,13 is along the miles of relative movement (two end face of flange dislocation displacement) of vertical cabin axon to direction in the formula 1, in the design of quasi double-hinge gate mechanism, dislocation displacement s can make the seal ring on the flange be subjected to shearing force and lose efficacy, so should avoid or make the value minimum of s as far as possible.By formula 1 as can be known, the rotational angle of hinge rear axle 10 is very little, can think definite value, the length of hinge connecting rod 9,14L also is definite value, so s is relevant with the cosine of the angle α of hinge connecting rod 9,14 axis and cabin body 1 axis in the dislocation displacement, when α 90 spends time dislocation displacement minimum, after promptly the gate is closed under the perfect condition, the axis of hinge connecting rod 9,14 should with the dead in line of hinge protecgulum 7,13.

Left side figure is that the back scheme drawing is closed at gate 4 under the perfect condition among Fig. 2, when the gate is opened, selects different axles as full rotating shaft, has two kinds of different situations.Suppose that hinge front axle 8 is full rotating shaft, shown in figure among Fig. 2; Suppose that hinge rear axle 10 is full rotating shaft, shown in right figure among Fig. 2.As can be seen from the figure, the running orbit minimum at gate when the gate opens and closes around hinge front axle 8, it is less that the gate moves required space, and this moment is comparatively desirable as full rotating shaft with hinge front axle 8.But, with the hinge front axle as full rotating shaft, when the gate is in open mode, the power that is subjected to of hinge connecting rod 9,14 is not in the plane at hinge connecting rod place up and down, upper hinge connecting rod 9 is subjected to the tensile force f that gate gravity P derives, following hinge connecting rod 14 is subjected to the thrust F1 that deadweight P in gate derives, and two power are spent near 90 with the plane angulation at hinge connecting rod place.Because up and down the hinge connecting rod is the plane steel framed structure, and is better to the power load effect in plane, steelframe place, plane, and to planar power load effect is not relatively poor.

From above-mentioned analysis as can be known, quasi double-hinge gate mechanism should not select hinge front axle 8 as full rotating shaft.Hinge rear axle 10 is during as full rotating shaft, when the gate moves, the plane steelframe formed of the plane steelframe formed of hinge protecgulum 7,13 and hinge connecting rod 9,14 up and down is positioned at same plane substantially up and down, and gate gravity P also is in this plane substantially, by strengthening the plane steelframe that hinge protecgulum 7,13 up and down forms and the intensity of the plane steelframe formed of hinge connecting rod 9,14 up and down, can offset power and the moment of gate deadweight to steelframe.

According to above conclusion design quasi double-hinge gate mechanism as shown in Figure 3, the linkage assembly drowing as shown in Figure 4, the top stress unit of hinge front axle 8 is a conical bearing 12, not only bear diametral load but also bear axial force, the bottom stress unit of hinge front axle is a cylindrical bearing 16, only bear diametral load, the top of hinge rear axle 10, bottom stress unit and hinge front axle are similar.Hinge protecgulum 7,13 can be around the 8 little rotations of hinge front axle, and hinge front axle and hinge connecting rod 9,14 usefulness keys are connected and fixed, and the hinge connecting rod can rotate around hinge rear axle 10 holoaxials, and hinge rear axle and hinge bonnet 11,15 usefulness keys are connected and fixed.Little commentaries on classics of hinge front axle is shipped and resell on another market with limit by the limit commentaries on classics connecting rod 19 that is installed in hinge front axle 8 middle parts and is followed closely 20 realizations, and the other end of limit commentaries on classics connecting rod and gate 4 and gate flange 3 usefulness steelframes are fixed.

Compensate function when occurring gate end face of flange and cabin body end face of flange when closing at the gate further combined with accompanying drawing 5 explanation quasi double-hinge gate mechanisms below and not fitting.Quasi double-hinge gate mechanism be because the linkage distortion that the deadweight of the sum of errors gate of process and assemble causes can cause linkage deviation theory design attitude, thus the situation that gate end face of flange and cabin body end face of flange are not fitted when the gate occurring and closing.Left side figure is the position view that the back linkage is closed at the gate under the perfect condition among Fig. 5, when linkage deviation theory design attitude in two kinds of situation: when hinge rear axle 10 falls within the design point right side, shown in figure among Fig. 5, gate, back flange is closed at the gate, and far-end contacts in that close hinge place is gapped with cabin body flange, hinge connecting rod 9,14 conter clockwises little commentaries on classics this moment, the little commentaries on classics of hinge protecgulum 7,13 cws can compensate the two end face of flange problem of not fitting; When hinge rear axle 10 falls within the design point left side, shown in right figure among Fig. 5, gate, back flange 3 is closed at the gate, and far-end is gapped contacting near hinge position with cabin body flange 2, the little commentaries on classics of hinge connecting rod 9,14 cws this moment, the little commentaries on classics of hinge protecgulum 7,13 conter clockwises can compensate the problem that two end face of flange are not fitted.

But the gyration θ of hinge front axle 8 limited rotations size and the length L 2 of hinge protecgulum 7,13 and axially do not fit relevantly apart from w as shown in Figure 6, are analyzed its geometric relationship and are obtained:

W=L2sin θ formula 2

From formula 2 as can be known, but gyration θ one is regularly, and hinge protecgulum 7,13L2 are long more, regulates not fit greatly more apart from w, suppose hinge protecgulum 7,13 long L2=150mm, design adjustable when not fitting apart from w 〉=10mm, but need spend gyration θ 〉=3.8.
