The specific embodiment
In each figure, in principle same reference marker is used for same parts.At each figure middle clamp plate formula switch locking frame 20 is to be illustrated from pure principle or from the details of this locking frame, so that locking has the tongue 12,14 of stock rail 16,18 or keeps the distance with stock rail.The tongue 12 that has stock rail 16 in Fig. 1 and Fig. 2 is by locking, and the tongue 14 of stock rail 18 usefulness but is opened in contrast.
The component design of each tongue 12,14 or stock rail 16,18 is given in configuration to be same and to arrange by looking-glass symmetry.Therefore respectively one of parts are described.
It is departure point that locking folder 34 supports 38 with clamping plate, clamping plate be supported on Figure 11-1,11 and Figure 12 in detailed introduction is arranged.Also being called as tongue connecting cleat support 38 has the U-shaped basic components 40 of a band side lever 42,44.By a bolt 54 that the side lever 44 on clamp cheek 30,32 and top is hinged.Bolt 46 is connected first axle that distributes on tongue 12 y directions.
Two board- like tongue links 46,48 for the reason of simplifying, are claimed that the tongue link is a link by basic components 40 rotary supportings below. Link 46,48 has a rectangular hole 50,52 respectively distolateral, and these two holes were connected bolt 54 at 46,48 o'clock at mounting and connection parts and contact, and this tie bolt passes basic components 40 and perpendicular to first distribution from oneself side.Therefore tie bolt 54 connects second axle, and link 46,48 can rotate around second axle.Link 46,48 its Background Region and the section that has a slot 50,52 contact and forwardly the zone keep the distance each other so that the flange of rail 56 of supporting tongue 12 and fix this flange of rail.The tie bolt 58 that for this reason distributes between link 46,48, this bolt can contact the flange of rail 56 of tongue 12.As shown in figure 12, tie bolt 58 is a departure point with the opening 67,68 of link 46,48.
Pressure-containing member or clamping part 70 act at the S shape of lateral plan middle and lower part longitudinal extension or the outside face of Z-shaped link 46, and pressure-containing member or clamping part are by board-like design-calculated and by the 72 real application forces that add of two belleville springs on link 46,48 and centre part 60 directions in the operation for example.Belleville spring 72 is supporting the bottom surface of board-like clamping part or pressure-containing member 70 in a side, is supporting the inboard of basic components 40 bottom side levers 42 at opposite side.In order to adjust, if possible, can be at belleville spring 72 and bearing cap shim 74 of side lever 42 installed inside.
Create this possibility by relevant therewith structure design, be that the tongue connecting cleat supports 38 basic components 40 and locking to press from both sides 34 holding positions constant, just not stock rail 16 vertically on carry out activity, although for example should be along stock rail 16 displacements based on temperature fluctuation tongue 12.This point has been done the explanation of pure principle by Fig. 4,5 and 6.The motion of link 46,48 is fixed between the link of the tongue flange of rail 56, can see that by this flange of rail clamping plate support 38 centre part 60 and basic components 40.All adjust for each parts of easy reason along common line 76, in this respect Fig. 4 shown one compare with zero-bit-the tongue stroke of mm, Fig. 5 has shown zero-bit, Fig. 6 shown one compare with zero-bit+motion of the tongue of mm, these demonstrations all are principles.Scheme drawing is seen people, and clamping plate support 38 and are not subjected to the influence of tongue 12 still the holding position is constant.This point is essential, is that the locking folder 34 of departure point must nothing places between the locking frame 20 obliquely because support 38 with clamping plate, with assurance as prescribed locking and release point tongue 12.
In order in the scope of necessity, to guarantee to support the sliding motion that carries out desired freedom from repairs on 38 piles of surfaces together, stipulated lubricating as from Figure 12, can knowing at clamping plate.The line that dense stroke goes out should be able to show the stroke of lubricant.People see, distributing along the center shaft of centre part 60 axle heads 66, first has the port 69 of lubricant reservoir.This port 69 is sealed with a lubricant head in upper area, so that can supply of lubricant in the scope of necessity.Can be in the outer end with a lid 73 sealing lubricant head 71, lubricant head can screw in the outer end, top of basic components 40 top side levers 44.
First port 69 leads in the groove 75 that distributes in basic components 62 bottom surfaces of centre part 60, and groove changes in the hole 68 that can contact basic components 62, and groove 78,80 is a departure point with this hole again, is distributed in the outside face of basic components 62.Groove 80 changes in the longitudinal slot 82 of axle head 64 distributions then.This longitudinal slot 82 is connected with groove 84,86, and groove 84,86 enters 46,48 piles of surfaces together of link.
In addition, axle head 64 is supported on the sliding bearing sleeve 90,92, and these of two sliding bearing sleeves are installed in the link on top, and another is installed on the following part connecting part of opening 61,63, and axle head 64 extends in these two openings.Opening 68 on top side lever 44 also correspondingly is equipped with a sliding bearing sleeve, and axle head 66 just is distributed in this bearing carrier ring.
First port on the axle head 66 or through hole 69 change over to and are arranged in second port 98 of tie bolt 58 in-to-ins.Second port 98 changes over to down in the lubricant reservoir 100 in the part connecting part 46 then, and groove 102 is stretched over down in the outside face of part connecting part 46 by second port 98, so that make clamping part and pressure-containing member 70 obtain desired lubricating.Coat sliding coating can in addition clamping part and pressure-containing member 70, just as doing on 62 piles of the basic components of giving centre part 60 surface and the surface of last part connecting part 48 together.
Therefore above-mentioned parts have and can move mutually in the scope of necessity, if it is adjustable relatively on it is vertical to face the tongue 12 of stock rail 16.
As seeing from Fig. 3, Figure 13, the bar 24,26 of locking frame 20 is passed by eccentric bolt 110,112.Supported by top eccentric bolt 110 at this corresponding bearing 28.Owing to used eccentric bolt 110, corresponding bearing 28 therefore bar 24,26 vertically on adjusted.
Same structure is arranged on eccentric bolt 112, therefore need not to further specify.
Shown in Fig. 7,8,9, running roller parts 122 are departure point with eccentric bolt 112, and these running roller parts are designed to the elasticity roller.Running roller parts 122 are called as the 5th running roller parts below.
Just can adjust distance between them by rotating eccentric bolt 110,112, so that by connecting rod the clamp cheek 30,32 that distributes between corresponding bearing 28 and the 5th running roller parts 122 is highly adjusted in the scope of necessity, link supports is on running roller parts 122.
Can see from Figure 14, Figure 15 that in addition cylindrical terminal block is supported on the sliding sleeve 111,113.Sliding sleeve wants the first-selected slip brass of using to make.Therefore can adjust eccentric bolt 110,112 without a doubt, particularly when needs are adjusted again.
As seeing from Figure 16, Figure 17, each clamp cheek-what introduce here is that clamp cheek 32-has an intermediate bar 124, and the external crossbar 126 of inverse bending is a departure point with this intermediate bar terminal.The external crossbar that is called as first external crossbar 126 that upwards straightens in the diagram supports 38 by bolt 46 and tongue connecting cleat and spins.At this bolt 46 anti-rotation device is housed.
Can see that clamp cheek 32 is identical with the clamp cheek that links to each other with tongue 14 of right side introduction among Fig. 1.The structure that will reemphasize parts whereby is identical.
The intermediate bar 124 of clamp cheek 30,32 interconnects by bolt 130 by its spacing, and this bolt is carrying the elasticity running roller 132 that is called as first running roller parts, and it is the corresponding bearing 28 of departure point that the elasticity roller contacts with locking frame 20 when tongue 12 lockings.
Exposing of 30,32 second external crossbars 128 of clamp cheek another bolt 133 is arranged between the terminal, this bolt is carrying second running roller parts 134 that can contact first crescent moon board slot 136.First crescent moon board slot is made up of a longitudinal rod 138 and a transverse bar 140 that bends towards longitudinal rod 138 on connecting rod 36 bottom surface directions that stretches along the longitudinal axis of connecting rod 36.Therefore first crescent moon board slot 136 has a L geometric figure.This longitudinal rod 138 and transverse bar 140 all first-selection a wedge angle is arranged.Another bolt 142 that is carrying the 3rd running roller parts 144 in addition is a departure point with the transitional region of pressing close to stock rail between intermediate bar 124 and first external crossbar 126.The 3rd running roller parts 144 can contact second crescent moon board slot 146 in each clamp cheek 30,32.This crescent moon board slot 146 roughly be distributed in connecting rod 36 vertically on.
The bolt 147 that is carrying the 4th running roller parts 148 at last is a departure point with first external crossbar 126 of clamp cheek 30,32 and the transitional region of intermediate bar 124.The bottom supporting of connecting rod 36 is on the 4th running roller parts.
As seeing from the detail drawing of Figure 18 and 19, bolt 46,133,142 all is an anti-rotation.Therefore can guarantee not occurred rotating by the rolling member 134,144 of these bolt bearings.
In addition, can also see from these figure that there is a hook-type extended part with the parallel distribution in bottom surface the bottom surface of connecting rod 36, a troffer 152 is being limited at this position.The running roller parts 122 that the front is referred to as the 5th running roller parts enter this troffer, and running roller parts 122 are being supported by eccentric bolt 112.Therefore when adjusting connecting rod 36, to during tongue 12 lockings, carry out clear and definite guiding,, otherwise may cause big application force thus so that the skew on the vertical direction does not take place to connecting rod.
In addition, with the exposing under the situation that front end keeps spacing of hook-type extended part 150, convex extended part 154 is a departure point with connecting rod 36 bottom surfaces, convex extended part 154 is called as camber member.When tongue 14 during by release fully, these parts work, that is to say that second running roller parts 134 enters the transitional region between first crescent moon board slot 136 longitudinal rods 138 and the transverse bar 140, so that connecting rod 36 rises and thereupon second running roller parts 134 fall along the direction of transverse bar 140, with the locking folder 34 that guarantees to control clamp cheek 30,32 steadily and move by connecting rod 36.Simultaneously clamp cheek 30,32 and locking folder 34 rises along with the tongue connecting cleat supports 38 together so that tongue 14 the adjustment period between rise so that after all opening, fall again.To correspondingly select camber member 154.Open position can be known from Fig. 9.Shown that in Fig. 8 tongue 14 is by the position of complete release.Locked position can be known from Fig. 7.
Scheme drawing also shows in addition, and the transitional region that intermediate bar 124 and tongue connecting cleat support between first external crossbar 126 that a side distributes is divided size by the plane, so that second crescent moon board slot 146 covered fully.Can guarantee that thus various fouls can not enter, consequently, the adjustability of locking folder 34 is protected all the time.Can also see in addition, be installed on the locking folder 34, first that rotates about it spool, can contact the 3rd running roller parts 144 of second crescent moon board slot 146 and roughly along to pass directions horizontal with connecting rod 36, the 4th running roller parts 148 that distribute on the first-selected vertical straight line.
As shown in figure 10, configuration gives the corresponding bearing 28 of first running roller parts 132 by a bearing surface 156 of being made up of two curve cambered plates, the extended part that two curve cambered plates are referred to as the dead point separates, roll running roller parts 132 and must cross this extended part, so that locking folder 34 perhaps can be removed from locked position by complete locking.Can guarantee at this dead point, release phenomenon out of control does not take place when locking point tongue 12.
Following effects power works during locking.Before tongue 12 was by locking, second rolling member 134 was positioned on the transverse bar 140 of crescent moon board slot 136. Clamp cheek 30,32 is by first axle, and just the locking folder 34 that distributes of bearing bottom and the 3rd running roller parts 144 distributing in second crescent moon board slot 146 and supported are so that form supporting role power P2.Second running roller parts, the 132 usefulness application force P3 that distribute in transverse bar 140 are supported on the inside dividing range 157 of transverse bar 140, as shown in Figure 8.First running roller parts 132 usefulness application force P4 are supported on the forward edge 158 of corresponding bearing 128 bearing surfaces 156.Locking folder 34 usefulness application force P5 are supported on its clamping plate support, just on first bearing.Tongue 12 is supported on the slide plate that does not add introduction with application force P6 in the one side.Last locking application force P7 acts between stock rail 18 and the tongue 14.For locking tongue 12 will be adjusted connecting rod 36 along the direction of arrow 212 with an application force PI among Fig. 1.
At this moment, the geometric relationship of first and second crescent moon board slot 136,146 and the distribution that contacts the running roller parts 134,144 of these crescent moon board slots all will be pressed from both sides support and the support situation of first running roller parts 136 on corresponding bearing 28 and bearing surface 156 thereof selected according to locking.For improving the 5th application force P5, along with the distance between stock rail 18 and the locking folder 34 is constantly dwindled, under the situation that first application force PI that acts on connecting rod 36 remains unchanged simultaneously substantially, the transverse bar 140 of bending or transverse bar 140 distributes on the clamping plate support according to the situation of second own running roller parts 134 bearing surface 157, and the bearing surface 157 that has longitudinal rod has like this just had a wedge angle or right angle and spool has been departure point the 3rd application force that distribute on longitudinal rod 138 directions of first crescent moon board slot 136 or after the horizontal adjustment with second running roller parts 134 thus.
