Description

  The present invention relates to a waterproof door device that mainly prevents water from entering and exiting a building or a parking lot.

In the waterproof door device, a waterproof door is provided in a pit (storage recess) embedded in the floor of an entrance / exit of a building or a parking lot, and the waterproof door is in a tilted state in which the opening of the storage recess is closed. From the position to the standing position where the entrance / exit is closed, it is pushed up by the turning arm of the raising / lowering device to stand. In Patent Document 1, a roller at the front end of a drive lever that swings back and forth is inserted in a gap between engagement rails provided on the back surface of the waterproof door. The roller rolls in the engagement rail and tilts the waterproof door. In Patent Document 1, since the waterproof door and the raising / lowering device are always integrally connected, the raising / lowering device does not operate both automatically and manually at the time of failure, so it is quite difficult to erect the waterproof door. There is a problem when performing inspections. In particular, if a component (swing lever, gear unit, etc.) that constitutes the raising / lowering device located under the waterproof door breaks down, the cover plate for inspection is opened and the swing is managed from there. The repair is very difficult because the lever is rotated or separated and the waterproof door is separated and the waterproof door is erected to perform repair.

  Further, when the second chain wheel 29 is rotated by driving the drive shaft 20, and the rotation arm 24 rotates about the intermediate shaft 23 via the endless chain 30 and the first chain wheel 28, the tip end portion of the rotation arm The guide roller 37 of 24a swings the waterproof door 3 upward in the up-and-down direction while moving the guide surface 26 relatively, and after the waterproof door 3 is raised by a predetermined amount, the guide roller 37 and the engaging groove 27 Are engaged with each other, and the rotating arm 24 and the waterproof door 3 are connected. Further, when the turning arm 24 is turned, the waterproof door 3 is erected while the connection between the turning arm 24 and the waterproof door 3 is maintained, and the turning arm 24 is moved in accordance with the upward movement of the guide member 25 in the tilt direction. As a result, the support arm distal end portion 22a to which the rotating arm 24 is attached is swung upward in the up-down direction around the drive shaft 20. In this embodiment, when the pivot arm 24 pivots so as to be substantially linear with respect to the support arm 22, the length of the pivot arm 24 and the support arm 22 is such that the waterproof door 3 stands substantially vertically. Is set. Further, the depth of the engagement groove 27 with respect to the guide surface 26 is perpendicular to the direction in which the rotation arm 24 extends to the guide roller 37 in a state where the rotation arm 24 and the support arm 22 are substantially linear. The force from the waterproof door 3 is set to act. In other words, in a state where the turning arm 24 and the support arm 22 are in a straight line, most of the external force (water pressure) from the waterproof door is obtained by the straight turning arm 24 and the support arm 22 via the guide roller 37. Will receive. For this reason, it is only necessary that the strengths of the rotating arm 24, the support arm 22, the drive shaft 20, the intermediate shaft 23, and the shaft member 38 can counter the external force, and the endless chain 30 hardly receives the external force from the waterproof door. It is sufficient that 30 is strong enough to raise and lower the waterproof door. A stopper 40 is disposed on the bottom plate 2d of the housing recess 2, and the stopper 40 abuts against the lower surfaces of the two support arms 22 until the waterproof door 3 rises a predetermined amount from the tilted state. Support.

  Next, the connection locking means 41 will be described. The connection locking means 41 includes a connection locking pin 42 disposed on the back side of the guide member 25 corresponding to the guide member 25, and a rotation member 43 provided on the hinge device 33 corresponding to the waterproof door base 3b.

The connection locking pin 42 is inserted and guided in the support hole 45 of the connection locking pin support member 44, and parallel to the guide surface 26 of the guide member 25, the door longitudinal direction on the opposite side of the door with respect to the engagement groove 27. It is possible to move forward and backward. The rotating member 43 is provided integrally with the second upper pivot 36a, that is, integrally with the upper end of the second link 35. The end of the connecting member 46 on the waterproof door base 3b side is rotatably connected to the rotating member 43, and the waterproof door of the connection locking pin 42 is connected to the end of the connecting member 46 on the waterproof door tip 3a side. The end on the base 3b side is rotatably connected. As the waterproof door 3 is turned upright, the rotation member 43 is rotated upward (in the right direction in FIGS. 4 and 5) integrally with the second link 35 and is moved horizontally through the connecting member 46 (FIG. 2). In this case, the lock pin 42 is moved from the unlocking position R2 below the engaging groove 27 so as not to face the engaging groove 27 (the state in which the guide member 25 and the rotating arm 24 can be separated) toward the waterproof door tip 3a side. In the upright state (FIG. 6), it is moved to a lock position R1 that engages with the back portion of the shaft member 38 engaged with the engagement groove 27 (position where the connection state of the rotating arm 24 and the guide member 25 is maintained). In addition, in the rotation from the standing state toward the horizontal position, the connection locking pin 42 is moved from the lock position R1 toward the lock release position R2 toward the waterproof door base 3b. To move. The drive device 39 is composed of the motor 16, the first and second chain wheels 28 and 29, and the chain 30, but the rotating arm 24 may be swung using a cylinder.
