Description

[Detailed description of the invention] Industrial application field The present invention relates to a safety device in the event of a fire in a multi-story parking lot.

Conventional technology Conventionally, when a fire breaks out in a multi-story parking lot, a sensor detects the heat, rings a bell and announces the occurrence of a fire, and then automatically lowers the shutter and fires a fire inside the multi-story parking lot. The fire was extinguished by supplying halon gas.

Problems that the invention aims to solve By the way, when the parking lot is full or when entering and exiting the parking lot is a hassle, you may park your vehicle at the entrance where the shutter is located. If a fire occurs under these conditions, the automatic shutter will cause damage to the vehicle. In contrast, recently, a system has been provided that automatically stops the shutter from lowering when a car hits the entrance/exit area. However, in this type, the shutter does not completely close the entrance and exit, so it is not possible to extinguish the fire using halon gas.

Means for Solving the Problem In order to solve the above problem, the safety device for a multi-story parking lot of the present invention detects cars at the entrance of a multi-story parking lot that is equipped with an automatic shutter connected to a fire detector at the entrance. A timer is provided that outputs an abnormal signal when a detection signal from the vehicle detection device is continuously input for a predetermined period of time or more, and an alarm device is provided that issues an alarm based on the abnormal signal from the timer.

Effect: According to this configuration, a car passing through the entrance/exit is detected by the car detection device, and the detection device from this detection device is input to the timer, but since the detection time is within the set time of the timer, the alarm device is activated. This alarm device does not issue an alarm. However, when the car is stopped at the entrance/exit area for a predetermined amount of time, the alarm device is activated by the output from the timer and issues a warning to the driver.

Embodiment An embodiment of the present invention will be described below based on the drawings.

FIGS. 1 and 2 show an example of a multi-story parking lot. Reference numeral 1 denotes a building, which has a loading/unloading work space 2 in the center and a plurality of floors on both sides of the loading/unloading work space 2. That is, the first floor 5, the second floor 6, the third floor 7, and the fourth floor 8 are formed by the pillar members 3 erected at appropriate intervals and the beam members 4 passed between the pillar members 3. 2nd to 4th floor 6,7,
8 has multiple parking areas (racks) 10 in the horizontal direction 9.
are formed into sections. These parking sections 10 are comprised of a pair of support rods in the horizontal direction 9 attached to the beam member 4 and a plurality of idle rollers attached to these support rods. The parking section 10 on the first floor 5 is divided by drawing white lines on the floor. On the first floor 5 in the loading/unloading work space 2, there is a pallet 1 for mounting on a vehicle.
A lift device 12 is provided for lifting the floor 1 to each floor 6, 7, 8. This lift device 1
2 consists of a drive unit 14 disposed in a recess 13 formed in the floor, a pantograph (a cylinder device may be used) 15 for telescopic vertical movement, and a lifting platform 16 attached to the upper end of the pantograph 15. When the lifting table 16 is lowered to its lowest position, the upper surface of the pallet 11 placed thereon is set to be flush or almost flush with the floor. Note that the number of lift devices 12 installed may be either single or multiple. Within the loading/unloading work space 2, trolleys 17 that can freely run in the horizontal direction 9 are provided corresponding to each of the second and higher floors 6, 7, and 8, respectively. This truck 17 has a pair of main frames 18 in the horizontal direction 9.
A pair of left and right sub-frames 19 connected between the ends of the main frame 18 form a framework with a lift space 20 in the center, and the running wheels attached to the ends of the main frame 18 are By supporting the running rail 21 provided on the lower surface of the carrying-in/out work space 2 of each floor 6 to 8, it is possible to move freely in the horizontal direction 9, and the running drive device is provided on the trolley 17 side. The trolley 17 is provided with a delivery device 22 that can freely deliver the pallets 11 to and from the parking section 10. This delivery device 22 includes a pair of movable tables 23A, 23B supported by the sub-frame 19 and movable in the horizontal direction 9, and these movable tables 23A, 2.
3B, a plurality of support rollers attached to the upper surfaces of both movable platforms 23A and 23B, and chain conveyors attached to the movable platforms 23A and 23B. 24 is a car, and a stopper 26 for receiving the wheels 25 is located on the pallet 1.
It is provided in 1. Near the entrance/exit 27, 1
A turntable 28 is provided on the fifth floor.

A shutter 30 that is moved up and down by a drive device 29 is disposed at each of the plurality of entrances and exits 27 . Appropriate location in a multi-story parking lot (behind the ceiling, etc.)
Fire detectors (sensors) 31 are arranged, and these fire detectors 31 are connected to the drive device 29. As shown in FIGS. 1 and 3, the entrance 2
7 is provided with a phototube type vehicle detection device 32 that emits a light beam to the side, for example. and car detection device 32
is connected to a timer 33 that outputs an abnormal signal when the detection signal from the vehicle detection device 32 is continuously input for a set time or more, and the timer 33 is further connected to the timer 33.
The timer 33 is connected to an alarm device 34 that issues an alarm in response to an abnormal signal from the timer 33.

In the multi-story parking lot with the above configuration, the parking work is carried out by first lowering the elevator platform 16 using the lift device 12,
The pallet 11 placed thereon is made flush with the floor surface of the first floor 5, and a car 24 is moved onto the pallet 11. The car 24 parked at a fixed position on the pallet 11 is raised together with the pallet 11 by the operation of the lift device 12, but at this time, the carts 17 on floors 6 to 8 to be stocked are placed directly above the lift device 12. At the same time, the movable bases 23A, 2
3B are spaced apart from each other. Therefore, the pallet 11 is positioned above the movable platforms 23A, 23B through the expanded elevating space 20, and then moved closer together with the movable platforms 23A, 23B and lowered by lowering the elevating platform 16. , the pallet 11 can be transferred to the trolley 17. Next, the trolley 17 is caused to run and stopped facing the target parking section 10,
The vehicle can then be stored in the parking section 10 by operating a chain conveyor or the like.

It should be noted that unloading can be performed by performing the reverse operation to that described above.

When a fire breaks out in a multi-story parking lot, the fire detector 31 detects the heat and smoke, issues various warnings, and then activates the drive device 29 to activate the shutter 3.
0 and close the entrance/exit 27. Thereafter, halon gas is supplied (details are omitted).

A vehicle 24 passing through the entrance/exit 27 is detected by a vehicle detection device 32
The detection time is determined by timer 3.
3 (for example, 5 seconds), no abnormality signal is output from the timer 33 to the alarm device 34, and this alarm device 34 does not operate. However, when the car 24 stops for longer than the set time, an abnormal signal is output from the timer 33 to the alarm device 34.
This alarm device 34 is activated and issues an alarm, such as an announcer or a buzzer, to the driver.

Effects of the Invention According to the safety device for a multi-story parking lot according to the present invention having the above configuration, when the vehicle is parked at the entrance/exit portion for a predetermined period of time, this can be detected and the warning device can issue a warning to the driver. Therefore, by faithfully following the warning, the driver can always clear the entrance/exit area, and the shutter can be reliably closed in the event of a fire emergency.
