[specific embodiment]
Further specify the present invention below in conjunction with accompanying drawing.
Single-shaft double-pin hinge type gate mechanism can be reduced to three-link mechanism, as shown in Figure 1, because single shaft (13) links to each other with single shaft connecting rod (11,12), and single shaft connecting rod (11,12) is fixed on the cabin body (1) by cabin body arc (5), easily the position of notice of invitation axle (13) is fixed, the bearing pin that double-pin (19,20) forms is movable axis, can move with front pin connecting rod (8,9) and gate, so the position is indefinite, link to each other with bearing pin connecting rod (9,10) between single shaft and double pin axle.If bearing pin connecting rod (9,10) length all is L, single shaft connecting rod (11,12) length all is L1, and front pin connecting rod (7,8) length all is L2.The design objective of single-shaft double-pin hinge type gate mechanism is to make the arm of force of whole mechanism the shortest, namely guaranteeing under the prerequisite that the pivot structure function realizes, bearing pin connecting rod (9,10) L, single shaft connecting rod (11,12) L1, front pin connecting rod (7,8) L2 should be the shortest.
Under the perfect condition, when the gate is closed, sell the position relationship of connecting rod (7,8), bearing pin connecting rod (9,10) and single shaft connecting rod (11,12) before supposing as shown in Figure 1, single shaft can not be parallel (namely with the axis of cabin body (1) with the plane at the axis place of double pin axle
), otherwise single shaft connecting rod (11,12) and bearing pin connecting rod (9,10) can " dead point " occur in single shaft (13) cooperation place, the angle of establishing between the axis of the axis of bearing pin connecting rod (9,10) and cabin body (1) is
When supposing single shaft (13) turned entirely as 360 °, double pin axle is limited rotating shaft, and determining of single shaft (13) position is relevant with the ability of regulating two end face of flange, supposes that the two end face of flange distance of not fitting is s, do not fit apart from s for compensation, the rotational angle of single shaft (13) is
From figure, can get following geometric relationship:
S is that front pin connecting rod (7,8) is along the miles of relative movement (two end face of flange dislocation displacement) of vertical cabin body axis direction in the formula 1, in the design of single-shaft double-pin hinge type gate mechanism, dislocation displacement s can make the seal ring on the flange be subject to shearing force and lose efficacy, so should avoid or make the value of s minimum as far as possible.By formula 1 as can be known, the rotational angle of single shaft (13) is very little, can think definite value, and the length of bearing pin connecting rod (9,10) L also is definite value, so the angle of dislocation displacement s and bearing pin connecting rod (9,10) axis and cabin body (1) axis
Cosine relevant, when
Time dislocation displacement is minimum, after namely the gate is closed under the perfect condition, the axis of bearing pin connecting rod (9,10) should with the dead in line of front pin connecting rod (7,8).
When the gate moves, select different axles to have different situations as full rotating shaft.Suppose that bearing pin is full rotating shaft, the running orbit at gate was minimum when the gate opened and closed around bearing pin, and it is less that the gate moves required space, and this moment is comparatively desirable as full rotating shaft with double pin axle.But with double pin axle as full rotating shaft, when the gate is in open mode, upper lower bearing pin connecting rod (9,10) power that is subject to is not at bearing pin connecting rod (9,10) in the plane at place, linkage is subject to the support reaction that gate gravity causes, connecting rod on the bearing pin (9) is subjected to pulling force, bearing pin lower link (10) is subjected to thrust, two power and bearing pin connecting rod (9,10) the plane angulation at place is near 90 °, because upper lower bearing pin connecting rod (9,10) be the flat steel shelf structure, better to the power supporting effect in plane steelframe plane of living in, and to planar power supporting effect is not relatively poor.
From above-mentioned analysis as can be known, single-shaft double-pin hinge type gate mechanism should not select double pin axle as full rotating shaft.Single shaft (13) is as full rotating shaft, when the gate moves, the plane steelframe basic bit that the plane steelframe that front pin connecting rod (7,8) forms and bearing pin connecting rod (9,10) form is in same plane, and gate (4) center of gravity also is in this plane substantially, by strengthening the intensity of the plane steelframe that plane steelframe that front pin connecting rod (7,8) forms and bearing pin connecting rod (9,10) form, can offset gate (4) deadweight to the force and moment of steelframe.
When structure design, stress unit adopts also definite relevant with full rotating shaft of plain bearing or antifriction-bearing box, stress unit in the full rotating shaft should adopt antifriction-bearing box, the antifriction-bearing box stress unit can be born larger force and moment, and full rotating shaft is done 360 ° when entirely turning, and antifriction-bearing box is less than plain bearing operation friction force.It mainly is to consider that its corner is less that the plain bearing stress unit is adopted in the limit rotating shaft, and plain bearing can satisfy its designing requirement, and the plain bearing process and assemble is convenient.
According to conclusions design single-shaft double-pin hinge type gate mechanism as shown in Figure 2, the single-shaft double-pin hinge type gate mechanism assembly drowing as shown in Figure 3.The upper stress unit of single shaft (13) is mainly realized by cylindrical roller bearing I (23), bear radial weight on the single shaft (13) with the cylindrical roller bearing II (24) of the lower stress unit of single shaft, the lower stress unit of single shaft (13) also comprises axial roller bearing III (25), and this bearing is only born axial force.The upper stress unit of bearing pin is top bearing shell (21), and the lower stress unit is bottom bearing shell (22), and top bearing shell is only born radial weight, and bottom bearing shell is not only born radial weight but also bear axial load.
Further specify compensate function when occurring gate flange (3) end face and cabin body flange (2) end face when single-shaft double-pin hinge type gate mechanism is closed at the gate and not fitting below in conjunction with accompanying drawing 1.Single-shaft double-pin hinge type gate mechanism be because the linkage distortion that the error of process and assemble and gate deadweight cause 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.Only need this moment single shaft (13) and collaborative little rotation of double-pin (19,20) can guarantee that gate end face of flange and cabin body end face of flange fit tightly.
The limit gyration is determined by expansion screw (27) regulating spring (26) amount of compression on the limit rotation mechanism (17,18).One end of limit bull stick (15,16) is connected respectively on the front pin connecting rod (7,8), locates and bear the shearing force of rotation with straight pin, is tightened by bolts and bears overturning couple, and limit bull stick (17,18) can rotate with the gate.The other end both sides of limit bull stick are connected with set screw (27), spring (26) amount of compression of installing in the set screw compression stop groove realizes the adjusting of limit gyration, the position of limit gyration and adjustable spring (26) is relevant with the length of bound bull stick, its structure principle chart as shown in Figure 4, by getting among the figure:
W=tu/ (u-v) formula 2
Because u is infinitely great, so t=w, i.e. the distance dependent of the axial adjustment at gate distance and set screw (27), and irrelevant with the length v of position-limited lever, this conclusion is conducive to reduce the distance between single shaft axis and limit shaft axis, makes the stressed more reasonable of linkage.
Single-shaft double-pin hinge type gate mechanism as can be known in sum: the collaborative little rotation by single shaft (13) and double pin axle (19,20) fits tightly gate flange (3) and cabin body flange (2); By making gate flange (3) be parallel to better cabin body flange (2) around double pin axle (19,20) fine setting, bearing pin connecting rod (9,10) and gate flange (3) design can be reduced in a plane perpendicular to axial gate flange (3) the dislocation displacement of cabin body (1) the largelyst.
