Description

[Detailed description of the invention] This invention relates to a supporting trolley restoring device for a watertight door installed in a seawall or the like.

In this type of watertight door that opens and closes the opening by moving laterally, the fixed guide rail that guides the wheels at the bottom of the watertight door is fixed from the lower front side of the opening to the side. .

However, once the watertight door has been moved to the opening, it must be moved toward the opening using an appropriate crimping device and the gasket around the watertight door must be crimped to the frame of the opening. A recess is provided by cutting out a portion, a cart is attached to this recess, and the watertight door is moved together with the cart toward the opening.

In order to open the watertight door that was pressed against the opening to close it, the watertight door must be moved backwards along with the trolley to align the fixed guide rail and the movable rail, and then the watertight door must be moved. However, there was a problem in that the work of retracting the watertight door in this way was extremely time consuming.

The purpose of this invention is to allow the watertight door to be easily retracted when the conventional watertight door is opened.

That is, in this invention, a restoring spring is provided on the supporting cart of the watertight door, and when the watertight door closes the opening, this spring is compressed and stores energy for restoring the door.
To provide a supporting cart restoring device for a watertight door, in which the watertight door is automatically restored together with the cart by a restoring spring when pressure on the watertight door is released.

The details of this invention will be explained below based on an embodiment shown in the attached drawings.

In Figures 1 and 2, 1 is a seawall, 2 is an opening thereof, and 3 is a watertight layer.

Reference numeral 4 designates a fixed guide rail fixed in a groove 5 provided from the lower front side of the opening 2 to the left side in FIGS. 1 and 2.

Reference numeral 6 denotes wheels installed near both ends of the lower edge of the watertight layer, and as shown in FIGS. , the outer periphery has a circumferential groove that engages with the rail 4.

A part of the fixed rail 4 near both ends of the opening 2 is cut out and a recess 9 is provided at the bottom of the groove 5 in this part, and the support cart 10 is fitted into the recess 9.

As is clear from FIGS. 3 and 5, this truck 10 is supported by a pair of front and rear rollers 11, which are rotatably attached to both ends of a pair of left and right side frames 12.

Moreover, a movable rail 13 having a cross section that matches that of the guide rail 4 is mounted on the upper side of the bogie 10. When the fixed waist bogie 10 moves backward and hits the rear wall of the recess 9, the fixed rail 4 and the movable rail 13 are aligned. Make sure they line up on the line.

In addition, a restoring spring 14 that touches the front wall of the recess 9 is attached to the front of the truck 10, and when no pressing force is applied to the truck 10 in the direction of the opening 2, the spring 14 causes the truck 10 to move backward. That's how it is.

Reference numeral 15 in FIGS. 1 and 3 denotes a plurality of levers provided in the watertight layer 3, which are attached to the lower part of the door 3 by a shaft 16, and the cam 17 at the lower part and the rear wall 18 of the groove 5 are used to push the levers A. Configure.

That is, when the lever 15 is horizontal, the cam 17 is also horizontal and does not touch the rear wall 18, but when the watertight layer 3 is moved in front of the opening 2 and the lever 15 is raised, the slope 19 of the cam 17 is moved.
pushes the rear wall 18 of the groove 5, and the reaction force pushes the door 3 forward,
When the highest part 20 of the cam 17 is pressed against the rear wall 18, the watertight layer 3 moves forward most, and the packing 21 around the front surface of the watertight layer 3 is configured to come into close contact with the peripheral frame 22 of the opening 2.

Further, at this time, the wheels 6 are placed on the movable rails 13 on the truck 10, and the truck 10 is moving forward together with the door 3.

Reference numeral 23 in FIG. 1 is an upper rail provided from the upper front side of the opening 2 to the left side in FIG. It guides the plurality of horizontal wheels 24 provided.

In addition, reference numeral 25 in FIGS. 1 and 2 is a crimp fixing member that fixes the watertight layer 3 with the opening 2 closed so that it does not move from side to side. This fixing member 25 is as shown in FIGS. It is closed by screwing into bolts 28 rotatably attached to the recesses 26 on both sides of the opening 2 of the seawall 1 by means of a shaft 27, and the bolts 28 are engaged with the notches of the engaging pieces 29 on both sides of the watertight layer. The fixing member 25 is rotated to hold the retaining piece 29, and it is retracted into the recess 26 so as not to get in the way when the door 3 is opened or closed.

This invention has the above-mentioned configuration, and when the watertight layer 3 is open, each trolley 10 is moved backward by the restoring spring 14, and the fixed rail 4 and the movable rail 13 are aligned, so the door 3 can be quickly opened. The opening 2 can be closed by moving it.

In this way, when the opening 2 is closed by the door 3 and each bundle 15 is erected, the door 3 moves forward together with the cart 10 by the action of the cam 17 as described above, and the opening 2 is closed.

Furthermore, in order to open the door 3 that closes the opening 2 in this way, each lever 15 is pushed down, and when the cam 17 and the rear wall 18 of the groove 5 are released, the carriage 10 moves backward together with the door 3 by the restoring spring 14. Since the movable rail 13 and the fixed rail 4 coincide, the door 3 is moved to the left in FIG. 1 to open the opening 2.

In this invention, as described above, the restoring force is applied to the support cart 10 of the watertight layer 3 by the restoring spring 14, so when the pressing device A is released in the closed state of the watertight layer 3, the restoring spring 14 automatically restores the cart 10. Since the rails 4 and 13 are aligned upon return, this is an extremely practical device that eliminates the need for the labor-intensive work of returning the support cart to its original direction as in the past.
