The state which contact | abutted to the side part water-tight surface 6a'-1, 6a'-1 of the part water-tight plate 6a-1, 6a-1 It is a schematic plan view of the hinge-type waterproof gate 1 which shows.

  In FIG. 4, necessary items are schematically shown, and other portions are omitted. Moreover, the phantom line shown by X2 of FIG. 4 shows the door-tight watertight surface including the opposing surface of each door-contact housing part 2a and 2a which opposes the door body 20, and the arrow X3 of FIG. 3 (see FIG. 2) shows a direction in which a load acts from a deeper water depth to a shallower water depth.

  As shown in FIG. 4 (a), the door body side hinge shaft portion 13b is pivotally supported by the rolling bearing 12e, and the door stop side hinge shaft portion 13a is pivotally supported by the slide bearing 11e. Then, it pivots about the door-body-side hinge shaft portion 13b that is pivotally supported by the rolling bearing 12e with a small friction coefficient (see FIGS. 3C and 3D). Therefore, when the hinge-type waterproof gate 1 is fully closed, the door 20 rotates around the door-side hinge shaft 13b and is disposed on the side hinge shaft 13 side (right side in FIG. 4). When the crushed portion 24b of the side watertight rubber 24-1 is crushed in contact with the side watertight surface 6a'-1 of the side watertight plate 6a-1, a repulsive force is generated in the door body 20.

For this reason, as shown to Fig.4 (a), the door body 20 will be in the state which the side (FIG. 4 left side) spaced apart from the side part hinge axis | shaft 13 of the door body 20 opened easily. In this case, as shown in FIG. 4, the shaft center O2 of the door body side hinge shaft portion 13b is eccentric from the shaft center O1 of the door stop side hinge shaft portion 13a, and the door pivotally supports the door stop side hinge shaft portion 13a. The door stop side bracket 11 provided with the contact side bearing portion 11d is fixed to the door stop housing portion 2a (see FIG. 3).

  Therefore, the door body 20 can be rotated around the door-side hinge shaft portion 13a with the eccentric distance between the door-side hinge shaft portion 13a and the door-body side hinge shaft portion 13b as a radius, and the door-side hinge shaft portion 13a. And the door body side hinge axial part 13b formed continuously can be made to function as a link mechanism using this eccentric distance.

  Accordingly, as shown in FIG. 4 (a), the door body 20 is further hinged after being stopped in a state where the side (left side in FIG. 4) that is separated from the side hinge shaft 13 of the door body 20 is open. By continuing the closing operation of the waterproof gate 1 and rotating the door body 20 toward the door stop housing 2a side (the upper side in FIG. 4A), the door stop side hinge shaft portion 13a becomes the side hinge portion 10 By the repulsive force of the side watertight rubber 24-1 on the side, it rotates in the B direction (opposite to the rotational direction in the closing operation) around O1.

  Thereby, the door body side hinge shaft portion 13b is moved in the direction away from the door stop housing portion 2a, the crushed portion 24b of the side watertight rubber 24-1 returns to the original state, and the door body 20 is moved to the door stop. It can be turned to the housing 2a side (upper side in FIG. 4A).

  Therefore, as shown in FIG. 4B, the door body 20 can easily close the door body 20 to the fully closed position arranged in parallel with the door-tight watertight surface X2. Thereafter, the door 20 is fixed by the lock device 7 or the like so as not to open without permission.

  Thereafter, as shown in FIG. 4 (c), when a hydraulic load in the direction of the arrow X3 acts on the door body 20, a pressing force is generated to move the door body 20 toward the door 6 (upper side in FIG. 4). . By this pressing force, the door stop side hinge shaft portion 13a can overcome the frictional resistance of the sliding bearing 11e (see FIG. 3) and can rotate in the direction of the arrow B ′, and the door body 20 moves the door stop side hinge shaft portion 13a. As the center, the eccentric distance between the door contact side hinge shaft portion 13a and the door body side hinge shaft portion 13b is rotated as a radius.

  Therefore, the crushing parts 24b and 24b of the side watertight rubbers 24-1 and 24-1 disposed on both sides of the door body 20 are the side watertight plates 6a-1 and 6a-1 located on both sides of the door body 20, respectively. The side pressure-tight plates 25a-1 and 6a'-1 are in contact with each other and are uniformly crushed. Therefore, the pressure bearing plates 25 facing both sides of the door body 20 are in contact with both sides of the door body 20 evenly. The load on the side can be evenly applied to the door-side housing 2a side, and the water pressure acting on the door 20 can be received on this housing-side.

  Accordingly, the hydraulic load is prevented from acting on the side hinge shaft 13 side (right side in FIG. 4) of the door body 20, and the side hinge shaft 13 constituting the side hinge portion 10 and the side hinge shaft 13 are The lifetimes of the sliding bearing 11e and the rolling bearing 12e (see FIG. 3) that support the shaft can be extended.

In particular, in the first embodiment of the present invention, as shown in FIG. 3, the door-side hinge shaft portion 13b is pivotally supported by the rolling bearing 12e, and the door-end side hinge shaft portion 13a is pivotally supported by the sliding bearing 11e. The friction coefficient of the bearing member on which the door-side hinge shaft portion 13b is pivotally supported is set smaller than the friction coefficient of the bearing member on which the door-side hinge shaft portion 13a is pivotally supported, thereby providing a difference therebetween. .

Therefore, in the normal case, the door body 20 is rotated about the door body side hinge shaft portion 13b that is pivotally supported by the rolling bearing 12e having a small friction coefficient, so that the door body 20 can be easily opened and closed. . Further, normally, when the door body 20 is brought into a fully closed state parallel to the door-tight watertight surface X2 by not actively rotating the door-side hinge shaft portion 13a, the door stop 6 and the side hinge Since the side hinge shaft 13 is set and held at a position where the side watertight rubber 24-1 on the side of the part 10 contacts, the side watertightness on the side hinge part 10 side when performing the closing operation to the fully closed position. The closing operation can be performed in a state where the rubber 24-1 is not crushed.

  Therefore, the resistance when performing the fully closed operation is only the rotational resistance of the rolling bearing 12e at the door body side hinge shaft portion 13b, so that the fully closed operation can be easily performed. Thereafter, a hydraulic load is applied to the door body 20, and the door body 20 is pushed toward the side watertight surface 6a'-1 side of the side watertight plate 6a-1, whereby the door-contacting hinge shaft portion 13a rotates. Since the side watertight rubber 24-1 abuts against the side watertight surface 6a'-1 of the side watertight plate 6a-1 and is uniformly crushed, the supporting pressure plates 25 on both sides of the door body 20 are replaced with the side watertight plate. 6a-1 can be reliably brought into contact with the side watertight surface 6a'-1.

  Thereby, the load by the side of the door body 20 can be made to act equally to the door stop housing part 2a side, and the water pressure which acts on the door body 20 can be received by this housing 2 side.

  In this way, a hydraulic load is prevented from acting on the side hinge shaft 13 side (right side in FIG. 4) of the door body 20, and the side hinge shaft 13 constituting the side hinge portion 10 and the side hinge shaft thereof. The lifespan of the sliding bearing 11e and the rolling bearing 12e (see FIG. 3) that support the shaft 13 can be extended.

By moving the lower flap 30 in an upright state, the lower watertight rubber 24-3 is brought into contact with the lower watertight surface 6a'-3 of the lower watertight plate 6a-3 and the upper surface 4a of the track rail 4 to thereby bring the door body 20 into contact. The bottom is watertight. The door body 20 includes a door body 21, a lower flap 30 disposed at a lower portion of the door body 20, and a lower hinge portion 32 that rotatably couples the lower flap 30 to the door body 21.

And the opening 21a of the door body 21 is closed, and the bearing portion 33b of the lower flap side bracket 33 and the holders 34, 34 disposed on both sides thereof are accommodated inside the box-shaped member. Therefore, even when the skin plate 23 is cut out and the opening 21a is provided, the water infiltrated by the watertight box 36 is blocked, so that it is prevented from entering the underground structure.

Next, attachment of the lower flap side bracket 33 to the door body 21 will be described. As shown in FIG. 6B, first, the lower hinge shaft 35 is inserted into the bearing hole 33b-1 of the bearing portion 33b of the lower flap side bracket 33, and the lower flap side bracket 33 into which the lower hinge shaft 35 is inserted. The bearing 33b is inserted into the opening 21a of the door body 21. Next, in a state where both ends of the lower hinge shaft 35 are in contact with the hinge shaft receiving recesses 21b-2 and 21b-2 of the shaft fixing members 21b and 21b, the holders 34 and 34 are held by the holding recess 21b− of the shaft fixing member 21b. 1, the holder 34 is attached to the shaft fixing member 21 b by bringing the holding portions 34 a of the holder 34 into contact with both ends of the lower hinge shaft 35, so that the lower flap side bracket 33 is attached to the door body 21. They are connected in a rotatable state. Therefore, the lower flap 30 can be rotated with respect to the door body 21.

  The axis O3 of the lower hinge shaft 35 protrudes from the surface 30a of the lower flap main body 31 (the surface on the downstream side in the hydraulic load direction) to the lower watertight plate 6a-3 (the surface 30a of the lower flap main body 31 (water pressure) The lower water-tight rubber 24-3 is arranged vertically below the axis O3 of the lower hinge shaft 35. The lower water-tight rubber 24-3 is disposed on the downstream side in the hydraulic load direction (the right side in FIG. 6A). It is installed.

  Therefore, as shown in FIG. 6A, the lower flap 30 has at least the lower flap main body because the lower watertight rubber 24-3 does not interfere with the track rail 4 until just below the axis O3 of the lower hinge shaft 35. The portion 31 can be rotated until the surface 30a (surface on the downstream side in the hydraulic load direction) of the portion 31 is disposed on the same plane as the surface 20a (surface on the downstream side in the hydraulic load direction) of the door body 21.

  Therefore, the lower part of the moving trajectory of the lower watertight rubber 24-3 installed on the lower flap 30 is located just before the bottom dead center of the moving trajectory, which is the point where the moving trajectory of the track rail portion 24 ″ -3 ″ is closest to the track rail 4 side. Since the flap 30 does not interfere with the track rail 4, the track rail portion 24 ″ -3 ″ of the lower watertight rubber 24-3 is brought into contact with the upper surface 4a of the track rail 4 at the bottom dead center of the movement track of the lower flap 30. be able to. In the first embodiment of the present invention, when the surface 30a of the lower flap main body 31 is arranged on the same plane as the surface 20a of the door main body 21, the movement locus of the lower flap 30 is the bottom dead center. (See FIGS. 5A and 5B).

  Therefore, as shown in FIGS. 5 (a) and 5 (b), when the lower flap 30 is rotated downward from the upwardly pulled state to the standing state, the lower watertight rubber 24-3 Since the track rail portion 24 ″ -3 ″ does not interfere with the track rail 4 until just below the axis O3 of the lower hinge shaft 35, the surface 30a of the lower flap main body portion 31 (the surface on the downstream side in the hydraulic load direction). Is arranged on the same plane as the surface 20a of the door body 21 (surface on the downstream side in the hydraulic load direction), the track rail watertight portion 24 ″ -3 ″ of the lower watertight rubber 24-3 is used as a track rail. 4 and the flap portion 24'-3 'of the lower watertight rubber 24-3 can be brought into contact with the lower watertight surface 6a'-3.

Thus, the lower watertight surface 6a'-3 can be set on the side watertight surface 6a'-1 and the upper watertight surface 6a'-2 on the same plane, side watertight surface of the side watertight plate 6a-1 6a' -1 (refer to FIG. 2A), the lower water-tight surface 6a'-3 of the lower water-tight plate 6a-3 and the upper water-tight surface 6a'-2 of the upper water-tight plate 6a-2 are made to be one surface and the quality control is performed simultaneously. Therefore, the accuracy control of the watertight surface can be facilitated and the watertightness can be improved, and the construction cost can be reduced because the accuracy control of only one watertight surface is sufficient.

  Further, as shown in FIG. 5C, the track rail watertight portion 24 ″ -3 ″ of the lower watertight rubber 24-3 is an end portion on the track rail 4 side of the fixed portion 24c of the track rail watertight portion. The track rail watertight portion 24d of the lower watertight rubber 24-3 is made to extend to the track rail by applying a hydraulic load to the track rail watertight portion 24d that extends from the rail to the lower flap 30 side and contacts the upper surface 4a of the track rail 4. The track rail watertight portion 24d of the lower watertight rubber 24-3 can be brought into close contact with the track rail 4 by pressing on the fourth side (lower side in FIG. 5C), and the watertightness of the track rail 4 can be improved.

  Next, with reference to FIG.7 and FIG.8, the upper structure of the door body 20 is demonstrated. FIG. 7 is an enlarged front view of the upper flap 50, FIG. 8 (a) is a plan view of the overhead wire portion watertight rubber 57, and FIG. 8 (b) is a front view of the overhead wire portion watertight rubber 57.

In addition, X1 of FIG. 7 is a line which shows the center of the door body 20, and arrow X3 of Fig.8 (a) has shown the hydraulic load direction. Further, the upper flap 50 of the door body 20 in the first embodiment of the present invention is targeted for a case where the movement in the lateral direction is relatively small (about 15 mm) or less.

  As shown in FIG. 7, the door body 20 (see FIG. 1) includes a main body 21-to which a hinge (upper side) door body side bracket 12 and a hinge (lower side) door body side bracket 12 (see FIG. 1) are attached. 1 and a door body main body 21 having an upper flap adjacent portion 21-2 disposed in a region on the door body side bracket 12 side (on the right side from the center line X1 in FIG. 7) from the center of the upper portion of the main body portion 21-1. An upper flap 50 disposed in a region (left side of the center line X1 in FIG. 7) surrounded by the upper flap adjacent portion 21-2 of the door body 21 and the body portion 21-1 of the door body 21.

The reinforcing portion 54c is a plate-like member that extends further upward (upper side in FIG. 7) along the long side of the upper surface of the fixed portion 54a, and is orthogonal to the support portion 54b between the pair of support portions 54b and 54b. Furthermore, the protrusion piece 54c-1 extended to upper side (FIG. 7 upper side) is provided.

The protruding piece 54c-1 holds a pin 54c-1a that is directed to the upper flap shaft 56 side, that is, the thickness direction of the main body 21-1 of the door body 21 (from the front to the back in FIG. 7). . The pin 54c-1a is located approximately in the middle between the pair of support portions 54b and 54b.

As shown in FIG. 7, the upper flap side bracket 5 5, the top flap body 51 for supporting the upper flap shaft 56 a bearing portion provided integrally with the main girder of the upper flap body 51 The connecting plate 55a extending from the end of the door body 21 of the door body 21 on the side of the body 21-1 to the body 21-1 side (lower side in FIG. 7) of the door body 21 and the width direction of the upper flap body 51 And a boss portion 55b which is a cylindrical boss extending in the left-right direction in FIG. 7 and projecting from the connecting plate 55a. The boss portion 55b of the upper flap side bracket 55 includes a bearing hole 55b-1 that is a hole in which the upper flap shaft 56 is pivotally supported and a pin 54c-1a that is held by the protruding piece 54c-1 of the door body side bracket 54. And a groove portion 55b-2 that is a groove that is inserted and moved.

The groove portion 55b-2 of the boss portion 55b of the upper flap side bracket 55 is formed in a spiral shape on the outer peripheral surface of the boss portion 55b. The groove 55b-2 extends obliquely in the axial direction of the upper flap shaft 56 (left and right in FIG. 7) with respect to the connecting plate 55a joined to the outer end surface of the boss 55b, and supports the door body 21. Compared with the end portion on the member 21-1a side (lower side in FIG. 7), the end portion on the main beam 51b side (upper side in FIG. 7) is arranged closer to the connection plate 55a side (right side in FIG. 7). That is, the end of the groove 55b-2 on the main girder 51b side (the upper side in FIG. 7) is close to the connecting plate 55a and the support member 21-1a side (the lower side in FIG. 7) of the door body 21 of the groove 55b-2. ) Is separated from the connecting plate 55a.

  As shown in FIG. 7, the upper flap shaft 56 is a shaft-like member, and both ends are fitted into insertion holes 54 b-1 and 54 b-1 provided in the pair of support portions 54 b and 54 b, and both ends thereof are fitted. It is fixed so as not to move in the axial direction (left-right direction in FIG. 7). The center portion of the upper flap shaft 56 is loosely fitted to the boss portion 55 b of the upper flap side bracket 55.

  Further, as shown in FIG. 7, the distance between the pair of support portions 54b, 54b (left-right direction in FIG. 7) is determined from the distance in the axial direction (left-right direction in FIG. 7) of the upper flap shaft 56 of the boss portion 55b. By setting it large, the boss portion 55b of the upper flap side bracket 55 is configured to be able to slide the upper flap shaft 56 in the axial direction (left and right direction in FIG. 7).

Moreover, the position of the groove 55b-2 inserted when the upper flap 50 is raised is the groove where the pin 54c-1a is inserted when the upper flap 50 is tilted in the hydraulic load direction (downward). Since the upper flap 50 is separated from the connection plate 55a from the position 55b-2, the upper flap 50 moves to the upper flap adjacent portion 21-2 side (right side in FIG. 7) of the door body 21 when it is raised.

  As shown in FIG. 7, the upper flap driving device 58 is a driving device for rotating the upper flap 50 up and down, and includes a rod 58b connected to a handle 58a (see FIG. 1), and a rod pin 58d connected to the rod 58b. The link member 58c is connected to the link member 58c by the link pin 58e.

  When the rod 58b is extended upward by the handle 58a, the upper flap 50 is moved upward about the upper flap shaft 56 of the upper flap 50 by the link member 58c, that is, downstream in the hydraulic load direction (from the front side to the rear side in FIG. 7). The upper flap 50 moves to the side while rotating, that is, moves obliquely upward, and the upper flap 50 is disposed on the side of the upper flap adjacent portion 21-2 of the door body 21 and is attached to the upper end of the upper flap 50. The watertight rubber 24-2 comes into an upright state in contact with the upper watertight surface 6a′-2 of the upper watertight plate 6a-2 (see FIG. 2B).

  Here, when the upper flap 50 is erected, the upper flap 50 is normally supported by the door body 21 in a state of being tilted to the door body 21 side, so that the side hinge portion 10 (see FIG. 1). ) To close the hinged waterproof gate 1 and then rotate the upper flap 50 upward by the upper flap driving device 58.

  As described above, when the upper flap 50 is rotated upward, the pin 54c-1a inserted into the groove 55b-2 moves along the groove 55b-2 on the upper flap adjacent portion 21-2 side of the door body 21 (see FIG. 7 right side), the upper flap 50 moves obliquely upward, and the upper watertight rubber 24-2 contacts the upper watertight surface 6a'-2 (see FIG. 2 (b)) of the upper watertight plate 6a-2. To stand up.

  That is, the upper flap 50 stands in the upper direction (from the front side of FIG. 7 to the back side in FIG. 7), and in the width direction of the upper flap body 51 (left and right direction in FIG. 7) on the upper flap adjacent portion 21-2 side of the door body 21. It moves to the upper flap adjacent part 21-2 side (right side in FIG. 7) of the door body 21.

  Therefore, by rotating the upper flap 50 upward, the upper flap 50 is disposed on the side of the upper flap adjoining portion 21-2 of the door body 21 to stand up, and the upper watertight rubber 24-2 is moved upward. The outer edge of the upper flap 50 is brought into contact with the upper watertight surface 6a'-2 (see FIG. 2 (b)) of the watertight plate 6a-2 and the flap side flap watertight rubber 52b is joined to the main body side flap watertight rubber 52a. Keep watertight. In addition, the flap side overhead wire portion watertight rubber 57b is joined to the main body side overhead wire portion watertight rubber 57a, and the overhead wire 5 is accommodated in the accommodation groove 57a-1 to be watertight.

That is, when the upper flap 50 is erected, the pin 54c-1a directed to the upper flap shaft 56 side provided above the flap side bracket 5 5, pin 54c-1a provided on the door body side bracket 54 And the groove portion 55b-2 that spirally extends in the circumferential direction of the upper flap shaft 56 along the axial center of the upper flap shaft 56 and slides along the upper flap 50 with the flap side overhead wire portion watertight rubber 57b. Is moved obliquely upward toward the upper flap adjacent portion 21-2 side of the door body 21 and joined to the main body side wire portion watertight rubber 57 a, and the overhead wire 5 is accommodated in the accommodation groove 57 a-1.

Therefore, since the overhead wire 5 can be accommodated in the accommodation groove 57a-1 only by raising the upper flap 50, the structure of the door body 20 can be simplified without the need for a moving device for moving the overhead wire portion watertight rubber 57. Can do. Further, since it is not necessary to move the overhead wire portion watertight rubber 57 independently from the standing of the upper flap 50, the process and operation of moving the overhead wire portion watertight rubber 57 are not required, and the hinged waterproof gate 1 is fully closed. The time required for the process and the fully closing operation can be reduced.

  Further, the flap side overhead wire portion watertight rubber 57b moves together with the upper flap 50, that is, the flap side overhead wire portion watertight rubber 57b does not move independently of the upper flap 50, so the upper flap 50 and the flap side overhead wire portion watertight rubber. The watertightness of the main body side overhead wire portion watertight rubber 57a does not move independently of the upper flap adjacent portion 21-2 of the door body main body 21, and thus the upper portion of the door body main body 21 can be improved. The water tightness between the flap adjacent portion 21-2 and the main body side wire portion watertight rubber 57a can be improved, and thus the water tightness between the flap side overhead wire portion watertight rubber 57b and the main body side wire portion watertight rubber 57a can be improved. Can do.

The upper flap side bracket 5 5 comprises a boss portion 55b which extends in the axial direction of the upper flap shaft 56, provided with a groove 55b-2 on the outer peripheral surface of the boss portion 55b, door main body side bracket 54 has a boss the provided protruding pieces 54c-1 that covers the outer peripheral surface of the part 55b, the pin 54c-1a to the projecting piece 54c-1 is retained, the curved periphery of the outward of the boss portion 55b of the upper flap side bracket bets 5 5 The groove 55b-2 can be formed on the surface, and the groove 55b-2 can be formed with a simple configuration.

As shown in FIGS. 8A and 8B, the overhead wire portion watertight rubber 57 has protrusions 57h-1 and 57h- extending to the downstream side (lower side in FIG. 8A) in the hydraulic load direction. 2 and its projecting portions 57h -1 and 57h-2 extend from the downstream end (lower side in FIG. 8A) in the hydraulic load direction to both sides (FIG. 8A left-right direction) of the door body 20. A rubber member provided with side portions 57g-1 and 57g-2 and formed in a T shape in plan view, and is L-shaped in plan view fixed to the upper flap adjacent portion 21-2 of the door body 21. The main body side overhead wire portion water-tight rubber 57a and a flat side L-shaped flap side overhead wire portion water-tight rubber 57b fixed to the upper flap main body 51 are configured.

  As shown in FIGS. 8A and 8B, the side surface of the protrusion side 57h-2 of the main body side wire portion watertight rubber 57a on the flap side overhead wire portion watertight rubber 57b side of the flap side overhead wire portion watertight rubber 57b. The main body side overhead wire portion of the projecting portion 57h-1 is joined to the side surface of the watertight rubber 57a side, and the overhead wire 5 is accommodated in the accommodation groove 57a-1. This accommodation groove 57a-1 (refer FIG.8 (c)) is formed in the side surface of the main body side overhead wire part watertight rubber 57a. Moreover, the side part 57g-2 of the main body side wire part watertight rubber 57a is installed on the rubber holder 57d attached to the upper flap adjacent part 21-2 of the door body 21. The side portion 57g-1 of the flap side overhead wire portion watertight rubber 57b is installed on a rubber holder 57d attached to the upper flap main body 51.

The main body side wire portion watertight rubber 57a includes an L-shaped hydraulic surface 57f which is a surface exposed to the outside of the side portion 57g and the projecting portion 57h, and a hydraulic load acts on the L-shaped hydraulic surface 57f. The water tightness around the overhead wire 5 can be improved.

  That is, when the L-shaped hydraulic surface 57f-1 of the main body side wire portion watertight rubber 57a and the L-shaped hydraulic surface 57f-2 of the flap side overhead wire portion watertight rubber 57b are pressed by a hydraulic load, the main body side wire portion The protruding portion 57h-1 of the watertight rubber 57a and the protruding portion 57h-2 of the flap side overhead wire portion watertight rubber 57b contract in a direction in which they are in close contact with each other, and the joint surface of the main body side overhead wire portion watertight rubber 57a and the flap side overhead wire portion watertight rubber Since the joining surface of 57b is closely attached and the overhead wire 5 accommodated in the accommodation groove 57a-1 is sandwiched between the joining surface of the main body side wire portion watertight rubber 57a and the joining surface of the flap side overhead wire portion watertight rubber 57b, When a load is generated, the water tightness around the overhead wire 5 can be improved.

  On the other hand, before the hydraulic load is generated, the protruding portions 57h-1 and 57h-2 of the overhead wire portion watertight rubber 57 are contracted in the direction of approaching each other due to the hydraulic load and are not in close contact with each other. The load acting on the overhead wire 5 can be made as small as possible without being sandwiched between the protrusions 57h-1 and 57h-2 of the watertight rubber 57.

  As shown in FIG. 8C, the main body side wire portion watertight rubber 57a includes a plurality of housing grooves 57a-1a and 57a-1b formed to coincide with the height of the overhead wire 5, and the plurality of housing grooves. 57a-1a and 57a-1b are grooves that penetrate in the thickness direction of the upper flap main body 51 (the vertical direction in FIG. 8A), and the overhead wire 5 is accommodated therein.

  As shown in FIG. 8C, the housing grooves 57a-1a and 57a-1b of the main body side wire portion watertight rubber 57a are formed in a trapezoidal shape whose cross-sectional area decreases from the downstream side to the upstream side in the hydraulic load direction. A rectangular shape in which the upstream side in the hydraulic load direction is formed in a semicircular shape along the outer shape of the overhead line 5, and the downstream side in the hydraulic load direction is set larger than the outer shape of the overhead line 5 and a gap appears around the overhead line 5. It is formed into a shape.

  On the upstream side of the housing grooves 57a-1 and 57a-1b in the hydraulic load direction, the overhead wire 5 is held in contact with the housing grooves 57a-1 and 57a-1b, and the water pressure in the housing grooves 57a-1 and 57a-1b. A gap appears around the overhead wire 5 on the downstream side in the load direction. Further, two receiving grooves 57a-1 and 57a-1b are formed in the vertical direction, and two overhead wires 5 are adjacent to the upper receiving groove 57a-1a in the width direction of the upper flap main body 51 (left and right direction in FIG. 7). The two overhead wires 5 are accommodated in the lower accommodation grooves 57a-1b so as to be adjacent to each other in the vertical direction.

  As shown in FIGS. 8A and 8B, the overhead wire 5 is accommodated in the accommodation grooves 57a-1a and 57a-1b formed in a trapezoidal shape whose cross-sectional area increases from the upstream side to the downstream side. . Therefore, although the overhead wire 5 contacts the receiving grooves 57a-1a and 57a-1b on the upstream side of the overhead wire 5 in the hydraulic load direction, a gap appears around the overhead wire 5 on the downstream side of the overhead wire 5 in the hydraulic load direction. Therefore, including the case where the overhead wire 5 has a longitudinal gradient, the overhead wire portion watertight rubber 57 is connected to the overhead wire 5 and the overhead wire when the door body 21 rotates to the track portion 3 (see FIG. 2A) side. In a portion excluding the watertight portion where the watertight rubber 57 comes into contact, the overhead wire 5 watertight rubber 57 interferes with the overhead wire 5 to the minimum, and an excessive external force is applied to the overhead wire 5 in the lateral direction (perpendicular to the track rail 4). The overhead wire 5 can be accommodated in the accommodating grooves 57a-1a and 57a-1b without acting.

  That is, the opening areas of the housing grooves 57a-1a and 57a-1b are the inner circumferences of the overhead wire 5 and the housing groove 57a-1 from the upstream side in the hydraulic load direction in which the overhead wire 5 and the inner surface of the housing groove 57a-1 are brought into contact with each other. Since a large gap is set on the downstream side where a gap is provided between the main body side overhead wire portion watertight rubber 57a and the flap side overhead wire portion watertight rubber 57b, an overhead wire is connected only on the upstream side in the hydraulic load direction. 5 is brought into close contact with the accommodation groove 57a-1, and watertightness is ensured.

Moreover, when the water pressure load is applied on the contact wire portion watertight rubber 57, the water pressure load L-shaped pressure surface 57f of the main body side contact wire portion watertight rubber 57a and the flap-side contact wire section watertight rubber 57 b acts, Since the hydraulic load acts in the direction of reducing the gap appearing around the overhead wire 5 on the downstream side of the overhead wire 5 in the hydraulic load direction, after the overhead wire 5 is accommodated in the accommodation grooves 57a-1a and 57a-1b, The water tightness of the overhead wire 5 can be improved when a load acts.

  In addition, as shown in FIGS. 8 (a), 8 (b), and 8 (c), in the first embodiment of the present invention, the housing groove 57a-1 is formed by an upper flap 50 that moves obliquely upward. It is provided not on the flap side overhead wire portion watertight rubber 57b provided on the main body side overhead wire portion watertight rubber 57a provided on the upper flap adjacent portion 21-2 (see FIG. 7) of the door body 21 that does not move in the vertical direction.

  Therefore, when the door body 20 moves, the positional relationship in the vertical direction with the receiving groove 57a-1 and the overhead wire 5 provided on the door body main body 21 side does not change, and the door body main body 21 (see FIG. 7) is not changed. The overhead wire 5 can be easily accommodated in the accommodation groove 57 a-1 of the overhead wire portion watertight rubber 57. Moreover, the overhead wire 5 is accommodated in the accommodation groove 57a-1 before the upper flap 50 moves to the door body main body 21, and compared with the case where the overhead wire 5 is accommodated in the accommodation groove 57a-1 that matches the shape of the overhead wire 5. Since the overhead wire 5 and the upper flap 50 do not interfere when the upper flap 50 is rotated, the lateral movement of the upper flap 50 can be set small.

Here, with reference to FIG. 9, the case where the external force which acts on the overhead wire 5 reduces by providing the accommodation groove | channel 57a-1 of this invention in the main body side overhead wire part watertight rubber | gum 57a is demonstrated. FIG. 9A is a plan view of a hinged waterproof gate 1 ′ provided with a main body side wire portion watertight rubber 57′a as a comparison object different from the main body side wire portion watertight rubber 57a of the present invention. (B) is a top view of the hinge-type waterproof gate 1 in 1st embodiment of this invention, and uses the main body side overhead wire part watertight rubber 57a of this invention. The arrow X3 in FIG. 9 indicates the hydraulic load direction (the direction in which the water immersed in the raceway portion 3 (see FIG. 2) flows), and L1 in FIG. 9A indicates the main body side wire portion watertight rubber 57a ′. 9B, L2 in FIG. 9B indicates the rotation trajectory of the body side overhead wire portion watertight rubber 57a. In addition, in the enlarged plan view of the main body side wire portion water-tight rubber 57′a in FIG. 9A, the hatched portion indicates the pushing portion, and Y indicates the pushing amount of the pushing portion.

  As shown in FIG. 9 (a), the main body side wire portion watertight rubber 57a as a comparison object different from the main body side wire portion watertight rubber 57a of the present invention is different from the housing groove 57a-1 of the present invention. An accommodation groove 57 ′ a-1 having a fixed shape is formed in the hydraulic load direction that matches the shape of the overhead wire 5.

  When the overhead wire 5 is accommodated in the accommodation groove 57 ′ a-1, when the door body 21 ′ rotates about the side hinge portion 10 to the overhead wire 5 side (left side in FIG. 9A), the side hinge The downstream end (upper side in FIG. 9A) of the accommodation groove 57 ′ a-1 in the hydraulic load direction is in contact with the overhead wire 5 just before the side 10. Further, the main body side overhead wire portion watertight rubber 57'a is in a state where the downstream end (upper side in FIG. 9A) of the accommodation groove 57'a-1 in the hydraulic load direction is in contact with the overhead wire 5, Since it pivots around the side hinge 10 until it is joined to the watertight rubber 57'b, the downstream end (upper side in FIG. 9 (a)) of the accommodation groove 57'a-1 in the hydraulic load direction. The overhead wire 5 is pressed.

  Therefore, as shown in FIG. 9A, a push-in portion crushed by the overhead wire 5 is generated in the main body side wire portion water-tight rubber 57′a, and the push-in portion shown by hatching in FIG. 9A is pushed. When the amount Y increases, an excessive load acts on the overhead wire 5.

  On the other hand, as shown in FIG. 9B, the door body main body 21 rotates around the side hinge portion 10, and the overhead wire 5 is accommodated in the accommodation groove 57a-1 of the main body side overhead wire portion watertight rubber 57a. In such a case, compared to the case shown in FIG. 9A, the overhead wire 5 is pressed to the downstream (upper side in FIG. 9B) end of the housing groove 57a-1 of the main body side overhead wire portion watertight rubber 57a. Indentation hardly occurs.

  That is, the receiving groove 57a of the present invention has a downstream end (upper side in FIG. 9B) in the hydraulic load direction which is a side first contacting the overhead wire 5 larger than the outer shape of the overhead wire 5 and a gap around the overhead wire 5. Is formed in a rectangular shape, so that the side hinge portion 10 can be rotated even if the door body 21 rotates about the side hinge portion 10 toward the overhead wire 5 (left side in FIG. 9B). This body side overhead wire portion watertight rubber 57a does not contact the overhead wire 5 just before the side. Further, the door body 21 rotates around the side hinge 10 and the main body side wire portion watertight rubber 57a is just before being joined to the flap side overhead wire portion watertight rubber 57b (next to the side hinge portion 10). The upstream end (the lower side in FIG. 9B) of the housing groove 57 a-1 of the body side overhead wire portion watertight rubber 57 a in the hydraulic load direction comes into contact with the overhead wire 5.

  Thus, since the overhead wire 5 is not pressed at the downstream end (upper side in FIG. 9B) of the housing groove 57a-1 of the main body side overhead wire portion watertight rubber 57a in the hydraulic load direction, it is shown in FIG. 9A. Compared to the case, there is no pushing part. Therefore, compared to the case shown in FIG. 9A, it is possible to prevent a load from acting on the overhead wire 5 when the door body 21 is rotated. On the other hand, since the overhead wire 5 and the accommodation groove 57a-1 are in contact with each other at the upstream end (lower side in FIG. 9B) of the accommodation groove 57a-1 in the hydraulic load direction, the water tightness around the overhead wire 5 is secured. Is secured.

  Next, a second embodiment in which the watertight rubber 76 of the present invention is used for the miter gate 70 will be described in detail with reference to FIGS. 10 and 11. FIG. 10 is a front view of the miter gate 70 according to the second embodiment of the present invention as viewed from the direction of hydraulic load (the direction in which the hydraulic load acts on the first door 71 and the second door 72 of the miter gate 70). FIG. 11A is a cross-sectional view of the miter gate 70 along the line XIa-XIa in FIG. 10, and FIG. 11B is a plan view of the overhead-line portion watertight rubber 76. FIG. c) is a front view of the overhead line watertight rubber 76 viewed from the direction opposite to the hydraulic load direction. A virtual line indicated by X4 in FIG. 11 indicates a door-to-door watertight surface.

As shown in FIG. 10, the miter gate 70 is a gate that prevents water from entering the underground structure, similar to the hinged waterproof gate 1 in the first embodiment of the present invention. In the direction in which the first door 71 and the second door 72 are close to each other with respect to the underground structure. In order to prevent interference between the side hinges 73, 73 that are pivotably connected, the track rail (not shown), the first door 71, and the second door 72, the first door 71 and the second door 72.

  Here, referring to FIG. 15, as the upper flap 150 rotates, the first stopper 88 rotates together with the upper flap side bracket 81 around the upper flap shaft 83 to change the position of the first stopper 88. The second link member 85 rotates about the second link shaft 87 with respect to the state and the door body side bracket 82, and the first link member about the first link shaft 86 with respect to the second link member 85. The state where 84 rotates and the position of the 2nd stopper 89 changes is demonstrated.

  As shown in FIG. 15, when the upper flap 150 falls, the first stopper 88 is disposed in a gap formed between the boss portion 81 b of the upper flap side bracket 81 and the bottom portion 84 b of the first link member 84. Is done. The first stopper 88 is in the longitudinal direction of the second stopper 89 fixed to the upper surface of the first link shaft 86, that is, in the axial direction of the upper flap shaft 83 (the left and right directions in the plan view and front view of FIG. 15). Adjacent. That is, the longitudinal side surface of the fixing portion 88a of the first stopper 88 (see FIG. 14D) and the longitudinal side surface of the fixing portion 89a of the second stopper 89 (see FIG. 14D) are mainly brought into contact with each other. ing.

  Due to this contact, the boss portion 81b of the upper flap side bracket 81 and the second link member 85 on which the first link shaft 86 is provided project from the axial direction of the upper flap shaft 83 (left and right in the plan view and front view of FIG. 15). Direction and relative displacement in the side view of the side view in FIG. 15 is restricted. That is, the first link member 84 cannot rotate around the first link shaft 86 with respect to the second link member 85.

  Further, the second link member 85 in which the relative displacement in the axial direction of the upper flap shaft 83 (the left and right directions in the plan view and the front view in FIG. 15 and the front side to the back in the side view in FIG. 15) is regulated is as follows. Two are provided in the axial direction of the upper flap shaft 83 (the left and right directions in the plan view and the front view of FIG. 15) (see FIGS. 12A and 13A). Therefore, the second link member 85 cannot rotate around the second link shaft 87 with respect to the door body side bracket 82 (see FIGS. 12A and 13A), and the upper flap 150 Is in a state in which the movement of the upper flap shaft 83 in the axial direction (the left-right direction of the plan view and the front view of FIG. 15 and the front side to the back side of the side view of FIG. 15) is restricted.

  As shown in FIG. 15, from the fall of the upper flap 150 to just before standing up, the upper flap 150 is in the axial direction of the upper flap shaft 83 (the left and right directions of the plan view and the front view of FIG. 15, and the side view of FIG. 15). Turned upward (upward in the side view of FIG. 15) about the upper flap shaft 83 with respect to the door body main body 1121 (see FIGS. 12 and 13) in a state in which the movement from the front to the back of the paper is restricted. To do. Following the upward rotation of the upper flap 150, the first stopper 88 and the upper flap 150 also rotate upward (upward in the side view in FIG. 15) about the upper flap shaft 83. Even after the first stopper 88 is rotated, the first stopper 88 and the second stopper 89 are adjacent to, or in contact with, the axial direction of the upper flap shaft 83 until just before the upper flap 150 rises. ing.

  As shown in FIG. 15, when the upper flap 150 stands, the surface 150a of the upper flap 150 is in contact with the upper door 6-2 (see FIGS. 12B and 13B). Rotation of the upper flap 150 centered on the downstream side in the hydraulic load direction (from the front side to the back side in FIGS. 12A and 13A) is restricted. On the other hand, the first stopper 88 is separated from the gap formed between the boss portion 81b of the upper flap side bracket 81 and the second link member 85, and the longitudinal direction of the first stopper 88 in the side view is the second link. The direction is perpendicular to the member 85.

  When the first stopper 88 is oriented in a direction perpendicular to the second link member 85, the first stopper 88 is separated from the second stopper 89 and becomes non-adjacent in the axial direction of the upper flap shaft 83. The first link member 84 is rotatable about the first link shaft 86 with respect to the second link member 85, and the second link member 85 is centered on the second link shaft 87 with respect to the door body side bracket 82. Can be rotated. Further, as described above, the first link shaft 86 and the second link shaft 87 are disposed in parallel and spaced apart by a distance Y1 (see FIG. 14).

  As shown in FIG. 15, after the upper flap 150 is erected, that is, after the first link member 84 and the second link member 85 are rotatable with respect to the second link member 85 and the door body side bracket 82, respectively. When the rod 158b (see FIGS. 12A and 13A) of the upper flap drive device 158 is moved upward, the second link member 85 is moved toward the door body side bracket 82 by the second link shaft. The upper flap is adjacent to the upper flap adjacent portion 1121-2 (right side in FIGS. 12A and 13A). Therefore, the first link member 84 pivotally supported by the first link shaft 86 has an arcuate locus with the radius of Y1 around the second link shaft 87 as the upper flap adjacent portion 1121-2 side (FIG. 12A ) And FIG. 13 (a) right side).

  Accordingly, when the second link member 85 is rotated around the second link shaft 87 after the upper flap 150 is erected, the upper flap 150 is centered on the second link shaft 87 from the position where the upper flap 150 is erected. It is possible to move to the upper flap adjacent portion 1121-2 side (right side in FIG. 12A and FIG. 13A) along an arcuate locus. In the third embodiment, the upper flap 150 moves 45 mm toward the upper flap adjacent portion 1121-2.

  In addition, as shown in FIG. 12 and FIG. 13, the first link member 84 is centered on the first link shaft 86 and is similar to the second link member 85 on the upper flap adjacent portion 1121-2 side (FIG. 12A and FIG. Since the second link member 85 rotates around the second link shaft 87, the axial direction of the upper flap shaft 83 is maintained, that is, the second link. While the second link member 85 rotates about the shaft 87, the axial direction of the upper flap shaft 83 is not changed by rotating the first link member 84 about the first link shaft 86.

  Therefore, the surface 150a of the upper flap main body 151 and the surface 1120a of the door body main body 1121 can be positioned in the same plane, and the flap side overhead wire portion watertight rubber 157b is joined to the main body side overhead wire portion watertight rubber 157a. The watertightness of the overhead line 5 'can be ensured.

  As described above, the overhead wire 5 'can be accommodated in the accommodation grooves 157a-1a and 157a-1b and the water tightness of the overhead wire 5' can be ensured only by performing the standing operation of the upper flap 150. The structure of the door 1120 can be simplified by eliminating the need for a moving device for moving the watertight rubber 157b and the main body side wire portion watertight rubber 157a. Moreover, since it is not necessary to move the flap side overhead wire portion watertight rubber 157b and the main body side overhead wire portion watertight rubber 157a independently of the standing of the upper flap 150, the steps of moving these overhead wire portion watertight rubbers 157a and 157b and By eliminating the need for operation, the process of fully closing the hinged waterproof gate 1000 and the time required for the fully closing operation can be reduced.

Further, since the moving distance of the upper flap 150 can be set by the separation distance between the first link shaft 86 and the second link shaft 87 axis, the separation distance between the first link shaft 86 and the second link shaft 87 can be set. By setting it large, the upper flap 150 can be moved greatly in the direction of the overhead line 5 '. In particular, the moving distance of the upper flap 150 can be increased corresponding to the case where the upper flap 150 has to be largely moved to the overhead line 5 side due to the structure of the overhead line 5 ′.

The flap side overhead wire portion watertight rubber 157b moves together with the upper flap 150. That is, since the flap side overhead wire portion watertight rubber 157b does not move independently of the upper flap 150, the upper flap 150 and the flap side overhead wire portion watertight rubber 157b Since the main body side wire portion watertight rubber 157a does not move independently of the upper flap adjacent portion 1121-2, the upper flap adjacent portion 1121-2 and the main body side wire portion watertight rubber Ki de be integral and 157a, can be improved watertightness can be reduced locations watertight is required between the flap-side contact wire section watertight rubber 157b and the body-side contact wire portion watertight rubber 157a .

  Further, as shown in FIG. 15, after the upper flap 150 is erected, that is, after the first link member 84 and the second link member 85 are respectively rotatable, the rod 158b of the upper flap drive device 158 (FIG. 12). When (a) and FIG. 13 (a)) are moved upward, the second stopper 89 and the second link member 85 together with the door body side bracket 82 are adjacent to the upper flap centering on the second link shaft 87. It rotates to 1121-2 side (FIG. 12 (a) and FIG. 13 (a) right side).

  Thereafter, when the flap side overhead wire portion watertight rubber 157b is joined to the main body side overhead wire portion watertight rubber 157a (see FIG. 13A), the rotation of the second link member 85 about the second link shaft 87 is stopped. The second stopper 89 is adjacent to the first stopper 88, that is, in the longitudinal direction of the second stopper 89. More specifically, the engaging portion 88b (see FIG. 14) of the first stopper 88 and the engaging portion 89b (see FIG. 14) of the second stopper 89 are the axes of the first link shaft 86 and the second link shaft 87. The contact is made in a right angle direction (vertical direction of the plan view and front view of FIG. 15).

  When the second stopper 89 and the first stopper 88 come into contact with each other, the rotation of the upper flap 150 around the upper flap shaft 83 relative to the door body main body 1121 (see FIGS. 12 and 13) is restricted, and the upper flap 150 is moved upward. The upper flap 150 can be reliably prevented from falling before being separated from the flap adjacent portion 1121-2.

  Therefore, after the upper flap 150 is erected and the flap side overhead wire portion watertight rubber 157b and the main body side overhead wire portion watertight rubber 157a are joined, when the upper flap 150 is toppled, first, the upper flap 150 is moved upward. After the lateral movement in the direction away from the flap adjacent portion 1121-2, the upper flap 150 is turned over. Accordingly, it is possible to prevent interference between the upper flap 150 and the overhead wire 5 'during the overturning operation of the upper flap 150 (see FIG. 13).

  Next, a fourth embodiment relating to the upper structure of the door body 1220 will be described with reference to FIGS. FIG. 16 illustrates a state in which the upper flap 250 of the hinged waterproof gate 1100 according to the fourth embodiment of the present invention is erected.

The arm portion 92b includes a second portion A link-side second fitting hole 92b-1 that pivotally supports the link shaft 97 is formed.

  As shown in FIG. 18, the upper flap shaft 93 is a shaft-shaped member having a circular cross section, and is fitted into the flap side fitting hole 91a of the upper flap side bracket 91 and is described later in a link side bearing hole 94a-1. The upper flap side bracket 91 is pivotally connected to the first link member 94.

  As shown in FIG. 18, the first link member 94 is formed in a U-shape (see FIG. 18A) facing downward from the side connected to the upper flap side bracket 91 and the second link member 95. The first link member 94 is a link member, and includes a bearing portion 94a that is a cylindrical member in which a link-side bearing hole 94a-1 in which the upper flap shaft 93 is pivotally supported and an outer periphery of the bearing portion 94a. A pair of arm portions 94b, 94b extending downward at a predetermined interval from the first side, and a link side first fitting hole 94b-1 into which the first link shaft 96 is fitted is formed in the arm portion 94b. It is installed.

  As shown in FIG. 18, the second link member 95 has a predetermined triangular thickness (see FIG. 18B) connected to the first link member 94 and the door body side bracket 92 and having a predetermined thickness. The link member is a link side second fitting hole 95a in which the first link shaft 96 is fitted in the upper corner portion and the link side third in which the second link shaft 97 is fitted in the lower corner portion. A fitting hole 95b is formed (see FIG. 18B), and a second stopper 99 is attached to a portion (side surface) having a thickness connecting the front surface and the back surface of the second link member 95 (see FIG. 18). 18 (a)).

  As shown in FIG. 18, the first link shaft 96 is a shaft-shaped member having an axial center extending in the vertical direction with respect to the front surface and the back surface of the second link member 95, and the second link shaft 97 is the first link shaft 97. A shaft-like member that is parallel to the link shaft 96, that is, has an axial center extending in the vertical direction with respect to the second link member 95, and the first link shaft 96 and the second link shaft 97 are axes of the first link shaft 96. They are spaced apart by a distance Y2 that is a line connecting the center O4 'and the axis O5' of the second link shaft 97.

As shown in FIG. 18, the first stopper 98, the outer peripheral surface a plate member having a substantially semi-crescent shape which is fixed to the outer side surface of the upper flap side bracket 91 is formed in an arc shape. The first stopper 98 includes a fixed portion 98 a that is a wide portion fixed to the upper flap side bracket 91 with a bolt, and an engaging portion 98 b that is a sharp pointed portion, and the engaging portion 98 b is provided on the upper flap 250. It is fixed so as to face downward (downward in FIG. 18A) when standing.

As shown in FIG. 18, the second stopper 99 is a rod-like member that is attached and fixed to the side surface of the second link member 95, and a fixing portion 99 a that is attached to the side surface of the second link member 95, and its fixing And an engaging portion 99b projecting in the axial direction of the upper flap shaft 93. The upper surface of the engagement portion 99 b is formed in an arc shape to match the outer circumferential surface of the first stopper 98.

  Here, referring to FIG. 19, as the upper flap 250 rotates, the first stopper 98 rotates together with the upper flap side bracket 91 around the upper flap shaft 93 to change the position of the first stopper 98. The second link member 95 rotates about the second link shaft 97 with respect to the state and the door body side bracket 92 and the first link member about the first link shaft 96 with respect to the second link member 85. The state where 94 rotates and the position of the 2nd stopper 99 changes is demonstrated.

  As shown in FIG. 19, when the upper flap 250 falls, the first stopper 98 has a fixed portion 98 a (see FIG. 18) that is a wide portion formed between the upper flap shaft 93 and the second stopper 99. The engaging portion 98b (see FIG. 18), which is a pointed portion, is disposed outside the gap (outside the outer shape line of the first link member 94). The outer peripheral surface of the fixing portion 98a of the first stopper 98 disposed in the gap is adjacent to the upper surface formed in the arc shape of the engaging portion 99b of the second stopper 99. That is, the upper surface formed in the arc shape of the engaging portion 99b (see FIG. 18) of the second stopper 99 and the outer peripheral surface formed in the arc shape of the fixing portion 98a (see FIG. 18) of the first stopper 98 are brought into contact with each other. I am letting.

  By this contact, the second link member 95 to which the second stopper 99 is fixed and the first link member 94 that is pivotally supported by the upper flap side bracket 91 to which the first stopper 98 is fixed are connected to the upper flap shaft 93. The relative displacement in the axial direction (left and right direction in the front view of FIG. 19) is restricted. That is, the first link member 94 cannot rotate about the first link shaft 96 with respect to the second link member 95, and the upper flap 250 is positioned in the axial direction of the upper flap shaft 93 (the front surface of FIG. 19). The third embodiment is the same as the third embodiment in that the movement in the left-right direction in the figure is restricted.

  As shown in FIG. 19, the upper flap 250 is in a state where the movement of the upper flap shaft 93 in the axial direction (left and right direction in the front view of FIG. 19) is restricted from the fall of the upper flap 250 to just before standing up. The first stopper 98 together with the upper flap 250 also rotates about the upper flap shaft 93 (FIGS. 16A and 17). (A) It is the same as that of 3rd Embodiment also in the point which moves to the back direction from the paper surface front.

Further, in accordance with the fourth embodiment, the first stopper 98, times around the upper flap shaft 93 along its outer peripheral surface in an arc shape which is formed in the upper surface of the engaging portion 99 b of the second stopper 99 Move. Therefore, even after the first stopper 98 is rotated, the first stopper 98 and the second stopper 99 are in the vertical direction (the vertical direction in the front view and the side view in FIG. 19) until immediately before the upper flap 250 stands. Are adjacent. That is, the upper surface formed in the arc shape of the engaging portion 99b of the second stopper 99 and the outer peripheral surface formed in the arc shape of the first stopper 98 are brought into contact with each other.

As shown in FIG. 19, when the upper flap 250 stands up, the upper flap 250 comes into contact with the upper door 6-2 (see FIGS. 16B and 17B), so that the upper flap shaft 93 is centered. Rotation of the upper flap 250 to the downstream side in the hydraulic load direction (from the front side to the back side in FIG. 16A and FIG. 17A) is restricted. On the other hand, the engaging portion 98 b of the first stopper 98 is separated from the gap formed between the lower surface of the upper flap shaft 93 and the upper surface of the engaging portion 99 b of the second stopper 99, and The engagement between the engagement portion 98 b and the engagement portion 99 b of the second stopper 99 is released, that is, the first stopper 98 and the second stopper 99 are in the axial direction of the first link shaft 96 and the second link shaft 97. Are spaced apart from each other.

  Therefore, the first stopper 98 and the second stopper 99 are not in contact with each other, and the second link member 95 can rotate around the second link shaft 97. Further, as described above, the first link shaft 96 and the second link shaft 97 are disposed in parallel and spaced apart by a distance Y2 (see FIG. 18).

  Further, as shown in FIG. 19, after the upper flap 250 stands, that is, the first link member 94 and the second link member 95 can rotate with respect to the second link member 95 and the door body side bracket 92, respectively. After that, when the rod 158b (see FIGS. 16A and 17A) of the upper flap driving device 158 is moved upward, the second link member 95 is adjacent to the upper flap around the second link shaft 97. It turns to the part 1121-2 side (FIG. 16 (a) and FIG. 17 (a) right side).

  Therefore, the second link member 95 has an arcuate locus with the radius of Y2 (see FIG. 18) around the second link shaft 97, and the upper flap adjacent portion 1121-2 side (FIGS. 16A and 17A). ) Move to the right). In the fourth embodiment, the upper flap 250 moves 45 mm toward the upper flap adjacent portion 1121-2.

  Therefore, when the second link member 95 rotates around the second link shaft 97 after the upper flap 250 stands up, the upper flap side bracket 91 connected to the first link member 94, that is, the upper flap 250 is From the position where the upper flap 250 stands up to the upper flap adjacent portion 1121-2 side (right side of FIGS. 16 (a) and 17 (a)) along an arcuate locus having a radius of Y2 around the second link shaft 97. Moving.

  In addition, since the first link member 94 also rotates together with the second link member 95 about the first link shaft 96, the second link member 95 does not rotate even if the second link member 95 rotates about the second link shaft 97. While the second link member 95 is rotating about the link shaft 97, the first link member 94 is rotated about the first link shaft 96, thereby maintaining the standing state of the upper flap 250. Therefore, the positional relationship between the upper flap main body 151 and the surface 1120a of the door body main body 1121 can be maintained, and the flap side overhead wire portion watertight rubber 157b is joined to the main body side overhead wire portion watertight rubber 157a so that the overhead wire 5 ' Watertightness can be ensured.

As described above, as in the third embodiment, the overhead wire 5 ′ is accommodated in the accommodation grooves 157 a-1 a and 157 a-1 b and the water tightness of the overhead wire 5 ′ is ensured only by performing the standing operation of the upper flap 250. Therefore, the structure of the door body 1220 can be simplified, and the process of moving the flap side overhead wire portion watertight rubber 157b and the main body side overhead wire portion watertight rubber 157a is not required and the hinged waterproof gate 1100 is fully closed. The time required for the operation process and the fully closed operation can be reduced.

  Further, since the moving distance of the upper flap 250 can be set by the separation distance between the first link shaft 96 and the second link shaft 97, the separation distance between the first link shaft 96 and the second link shaft 97 is increased. By setting, the upper flap 250 can be largely moved in the direction of the overhead line 5 ′. In particular, the movement distance of the upper flap 250 can be increased corresponding to the case where the upper flap 250 has to be largely moved toward the overhead line 5 ′ due to the structure of the overhead line 5 ′.

  Similarly to the third embodiment, the upper flap 250 and the flap side overhead wire portion watertight rubber 157b can be integrated, and the upper flap adjacent portion 1121-2 and the main body side wire portion watertight rubber 157a are integrated. Therefore, the number of places where watertightness is required between the flap side overhead wire portion watertight rubber 157b and the main body side overhead wire portion watertight rubber 157a can be reduced, and the watertightness can be improved.

  As shown in FIG. 19, after the upper flap 250 stands up, that is, after the first link member 94 and the second link member 95 are respectively rotatable, the rod 158b of the upper flap drive device 158 (FIG. 16 ( When a) and FIG. 17 (a)) are moved upward, the second stopper 99 and the second link member 95 together with the door body side bracket 92 are centered on the second link shaft 97 and the upper flap adjacent portion 1121. -2 side (FIG. 16 (a) and FIG. 17 (a) right side).

  Thereafter, when the flap side overhead wire portion watertight rubber 157b is joined to the main body side overhead wire portion watertight rubber 157a, the rotation of the second link member 95 about the second link shaft 97 stops and the second stopper 99 becomes the first stopper. Adjacent to 98. Specifically, the inner side surface of the engaging portion 98b (see FIG. 18) of the first stopper 98 and the side surface of the engaging portion 99b (see FIG. 18) of the second stopper 99 are the first link shaft 96 and the second link. Contact is made in the axial direction of the shaft 97 (the vertical direction of the plan view and front view of FIG. 19).

  When the second stopper 99 and the first stopper 98 come into contact with each other, the rotation of the upper flap 250 around the first link shaft 96 with respect to the door body main body 1121 (see FIGS. 16 and 17) is restricted. Falling can be prevented.

  Therefore, after the upper flap 250 stands up and the flap side overhead wire portion watertight rubber 157b and the main body side overhead wire portion watertight rubber 157a are joined, when the upper flap 250 is turned over, After the lateral movement in the direction away from the flap adjacent portion 1121-2, the upper flap 250 is turned over. Therefore, interference between the upper flap 250 and the overhead wire 5 'can be prevented during the overturning operation of the upper flap 250.

Furthermore, with reference to FIG. 20, a description will be given orbital rail watertight unit 60. 20A is a plan view of the track rail watertight portion 60, and FIG. 20B is a front view of the track rail watertight portion 60 viewed from the direction of arrow XXb in FIG. 20A.

The track rail watertight rubbers 62b and 62d installed on the inner rail side of the track portion 3 (the side where the wheel flanges of the railway vehicle are located) are used so that they do not interfere with the wheel flanges of the railcar. It is configured to be lower than 62a and 62c. Further, the track rail watertight portion 60 is disposed so as to face the center of the track portion 3 and is formed in a wedge shape so as to be fitted to the track rail watertight rubbers 62 a, 62 b, 62 c, 62 d wedge-shaped hardware 65. The Therefore, the track rail watertight rubbers 62 a to 62 d are structured not to come out of the track rail 4 when a hydraulic load is applied.

  As shown in FIGS. 20A and 20C, the rubber fixing member 63 is a member for fixing the track rail watertight rubber 62, and is constituted by bolts 63a and 63a and nuts 63b and 63b. Has been.

Since the same applies to the side track rail watertight rubbers 62b and 62d disposed on the inner track side, the description thereof is omitted. Moreover, since the split pin is provided at the tip of the bolt 63a, the nut that is screwed to the bolt 63a is prevented from falling off due to vibration generated when the railway vehicle passes through the track portion 3.

  As shown in FIGS. 20 (a) and 20 (c), the pressing plates 64, 64 are plate-like members attached to the end surfaces of the wedge-shaped track rail watertight rubbers 62a, 62c facing each other, and are bolts 63a. The head and the nut 63b are supported. By screwing the nut 63b into the bolt 63a, the pressing plates 64 and 64 are pressed in the directions approaching each other, and the wedge-shaped track rail watertight rubbers 62a and 62c are compressed.

The track rail watertight rubber 62 is inserted between the inner side surface 65a of 65 and the side surface 4b recessed inside the track rail 4, and the track rail watertight rubber 62 is fitted to the wedge-shaped inner side surface 65a of the wedge-shaped hardware 65. Thus, the track rail watertight rubber 62 is in close contact with the wedge-shaped hardware 65 and the track rail 4, and the periphery of the track rail 4 has a watertight structure.

  As shown in FIG. 20A, the side adjustment plate 66 is a plate-like member disposed between the side portion 61a of the track rail installation portion 61 and the outer surface 65b of the wedge-shaped hardware 65, It is fixed to the side portion 61a of the track rail installation portion 61 together with the wedge-shaped hardware 65 by an adjustment plate fixing member 67 described later. This side adjustment plate 66 is formed in the width direction of the empty track rail 4 formed between the side portion 61a of the track rail installation portion 61 and the side surface 4b of the track rail 4 (FIG. 20 (a) left and right direction). It is configured to be selectable corresponding to the dimensions L1 and L2, and when the track rail watertight rubber 62 is attached to the track rail 4, a suitable one is selected from a plurality of dimensions by measuring the dimensions L1 and L2, and the track rail is installed. It is disposed between the side portion 61 a of the portion 61 and the outer side surface 65 b of the wedge-shaped metal piece 65.

As shown in FIG. 20A, the adjustment plate fixing member 67 is a member for fixing the wedge-shaped metal piece 65 and the side portion adjustment plate 66 to the side portion 61a of the track rail installation portion 61, and includes a bolt 67a. And a nut 67b. The nut 67b is provided on a side surface of the side portion 61a of the track rail installation portion 61 (a side surface opposite to the side surface joined to the side portion adjusting plate 66, outside the right side portion 61a in FIG. 20A). The nut 67b is welded to the side portion 61a of the track rail installation portion 61 in order to prevent the bolt 67a from being screwed when the nut 67b is loosened due to vibration generated by the passage of the railway vehicle. ing.

The wedge-shaped metal piece 65 and the side adjustment plate 66 are provided with a screwing hole 69 that is a hole penetrating in the width direction of the track rail 4, and a bolt 67a is screwed into the screwing hole 69 and the nut 67b. The wedge-shaped metal piece 65 and the side adjustment plate 66 are fixed to the lower door 6-3.

  The wedge-shaped hardware 65 has a bolt recess 65 a-1 that is a recess that is reduced in diameter on the side adjustment plate 66 on the inner surface 65 a of the wedge-shaped hardware 65 (the side surface on the track rail 4 side that fits the track rail watertight rubber 62). Since the head 67a-1 of the bolt 67a is accommodated in the bolt recess 65a-1, the head 67a-1 of the bolt 67a interferes with the track rail watertight rubber 62 when the track rail watertight rubber 62 is inserted. The track rail watertight rubber 62 can be easily inserted.

In this way, the inner surface 65a of the wedge-shaped metal piece 65 and the track rail 4 are arranged by the side adjustment plate 66 disposed between the side part 61a of the track rail installation part 61 and the outer side surface 65b of the wedge-shaped metal piece 65 . After adjusting the gap formed between the side surface 4b so that the dimension in the width direction of the track rail 4 (the left-right direction in FIG. 20A) is constant, the track rail watertight rubber 62 is inserted into the gap. Therefore, adjustment such as cutting of the track rail watertight rubber 62 becomes unnecessary.

  In other words, the space formed between the side portion 61a of the track rail installation portion 61 and the side surface 4b of the track rail 4 due to the installation of the track rail 4 or the like is caused by an error in the position of the track rail. Although a dimensional error occurs in the width direction (FIG. 20 (a) left and right direction), the side adjustment plate 66 can be selected in accordance with the dimensional error, so the dimensions L1 and L2 of the voids are measured. A suitable one is selected from a plurality of types, and the width direction of the track rail 4 in the gap formed between the inner side surface 65a of the wedge-shaped hardware 65 and the side surface 4b of the track rail 4 (FIG. 20 (a) left and right) The direction dimension can be adjusted to a certain specified value.

  Therefore, when the track rail watertight rubber 62 is inserted, the size of the gap can be set to a specified value corresponding to the size of the track rail watertight rubber 62. The adjustment work such as cutting the rail watertight rubber 62 is unnecessary, the insertion work of the track rail watertight rubber 62 can be easily performed, the burden on the operator can be reduced, and the track rail installation portion of the wedge-shaped hardware 65 can be reduced. The width direction (FIG. 20 (a) left-right direction) of the track rail 4 of the clearance formed between the side portion 61a of the track rail 61 and the side surface 4b of the track rail 4 and the track rail 4 of the track rail watertight rubber 62 Since the width dimension can be matched, the watertightness around the track rail 4 can be improved.

  Also, as shown in FIG. 20B, the lower adjustment plate 68 is disposed between the opposing wedge-shaped hardware 65 and between the lower surface 4c of the track rail 4 and the bottom 61b of the track rail installation portion 61. A vertical member of the track rail 4 in the empty space formed between the side portion 61a of the track rail installation portion 61 and the side surface 4b of the track rail 4 (FIG. 20 (b) vertical direction). Is arranged between the lower surface 4c of the track rail 4 and the side portion 61a of the track rail installation portion 61 in correspondence with the dimension L3 generated in FIG.

  Thus, by arranging the lower adjustment plate 68 between the lower surface 4c of the track rail 4 and the bottom 61b of the track rail installation portion 61, the bottom portion 61b of the track rail installation portion 61 and the lower surface 4c of the track rail 4 The gap between the lower surface of the track rail 4 and the bottom of the track rail installation portion 61 is filled by selecting the thickness of the lower adjustment plate 68 corresponding to the dimensional error in the height direction of the track rail 4 between The track rail 4 can be reliably supported.

  The lower adjustment plate 68 is not limited to a plate-like member, and can function as the lower adjustment plate 68 by adjusting the placement height of the concrete placed on the lower door 6-3.

  Here, the process of attaching the track rail watertight rubber 62 to the track rail 4 will be described. First, in a state where the lower door unit 6-3 on which the track rail installation unit 61 is installed is installed on the track unit 3, the door unit housing part 2a is placed, so that the lower door unit 6-3 is changed to the door unit housing unit. It is held at 2a and installed on the track portion 3 (see FIG. 1).

Next, the track rail 4 is temporarily installed in the recess 6 b of the lower door 6-3, and the dimensions of the void formed between the side surface 4 b of the track rail 4 and the side portion 61 a of the track rail installation portion 61, and L1 and L2 and the dimension L3 of the void formed between the lower surface 4c of the track rail 4 and the bottom 61b of the track rail installation portion 61 are measured. The side adjustment plate 66 corresponding to the dimension is selected according to the dimension in the width direction (FIG. 20 (a) left-right direction) of the empty track rail 4 measured by this measurement.

  Similarly, the lower adjustment plate 68 corresponding to the dimension L3 in the height direction (the vertical direction in FIG. 20A) of the empty track rail 4 is selected.

After that, the temporarily installed track rail 4 is removed, and the side adjustment plate 66 is joined to the side portion 61a of the track rail installation portion 61 of the lower door 6-3 as shown in FIG. 61a is joined to a wedge-like hardware 65, the track rail 4 side (FIG. 20 (a) right side) the bolts 67a inserted from screwed into a nut 67 b which is fixed to the side 61a of the track rail installation section 61, The side adjustment plate 66 and the wedge-shaped hardware 65 are fixed to the side portion 61a of the track rail installation portion 61, that is, the lower door stop 6-3. Thereafter, the lower adjustment plate 68 is installed on the bottom 61b of the track rail installation portion 61 of the lower door 6-3, and the track rail 4 is installed and attached to the recess 6b of the lower door 6-3 (see FIG. 1). .

As shown in FIG. 20, outer rail-side track rail watertight rubbers 62a, 62c facing each other between the side surface 4b of the attached track rail 4 and the wedge-shaped hardware 65 are provided along the track rail 4 (FIG. 20 ( a) Vertical direction) Insert. In this case, the track rail watertight rubber 62a on the downstream side in the hydraulic load direction is inserted from the downstream side (upper side in FIG. 20A) in the hydraulic load direction, and the rear track rail watertight rubber 62c on the upstream side in the hydraulic load direction is hydraulically loaded. It inserts from the direction upstream side (FIG. 20 (a) lower side).

  Then, as shown in FIG. 20 (c), a pair of pressers joined to the outer rail side track rail watertight rubbers 62a and 62c facing each other and the end surfaces of the outer rail side track rail watertight rubbers 62a and 62c, respectively. The bolts 63a are inserted into the plates 64 and 64, and the nuts 63b are screwed into the bolts 63a, so that the center-side track rail watertight rubbers 62a and 62c are compressed toward each other, and the center-side track rails are compressed. The watertight rubbers 62 a and 62 c are fixed by being crimped to the side surface 4 b of the track rail 4 and the inner side surface 65 a of the wedge-shaped hardware 65. Since the same applies to the track rail watertight rubbers 62b and 62d on the inner track side, the description thereof is omitted.

  Accordingly, the inner side surface 65a of the wedge-shaped hardware 65 and the side surface 4b of the track rail 4 are arranged by the side adjustment plate 66 disposed between the side portion 61a of the track rail installation portion 61 and the outer surface 65b of the wedge-shaped hardware 65. Since the gap formed between the rails 4 is adjusted so that the dimension in the width direction of the track rail 4 (the left-right direction in FIG. 20A) is constant, the track rail watertight rubber 62 is inserted into the gap. Adjustment work such as cutting of the track rail watertight rubber 62 to adjust the rail watertight rubber 62 to its dimensions is unnecessary, and the work of inserting the track rail watertight rubber 62 can be easily performed, reducing the burden on the operator. In addition, the dimension in the width direction of the track rail 4 between the wedge-shaped hardware 65 and the track rail 4 and the dimension in the width direction of the track rail 4 of the track rail watertight rubber 62 can be matched. Since it is, it is possible to improve the water tightness of the track rail watertight rubber 62.
