Description

[Detailed explanation of the idea] Industrial applications This invention relates to a multi-story parking lot.

2. Description of the Related Art A multi-story parking garage is constructed by allowing vehicles to enter and exit a parking section formed on multiple levels using a transportation device. In order to increase storage efficiency, the vertical height (space height) of the parking area is made as low as possible. Furthermore, in order to store tall cars, for example, a parking area with a high vertical height is installed on the top floor. is forming. To this end, a height detection device is installed in the vehicle's running area, and cars that are not detected by this height detection device are parked in the normal parking area, while cars that are detected by the height detection device are parked in the parking area on the top floor. are doing.

Problems that the invention aims to solve By the way, especially recent cars have antennas, and if you leave the antenna out and forget to put it in, the height detection device will not detect the height of the car itself, but the antenna will be high. Contact with the detection device (collision)
I often do it. In this case, since the antenna has no rigidity and is easily bent or broken, the antenna itself will bend or break before the height detecting device is activated.
Furthermore, since the vehicle is stored in the parking area on the lower floor, it comes into contact with the side beams and is more likely to bend or break.

Means for Solving the Problem In order to solve the above-mentioned problems, the antenna detection device for a multi-story parking lot according to the present invention provides an antenna detecting device for a multi-story parking lot that is located in front of the detection position by the height detection device in the car running section of the multi-story parking lot.
A pair of upper and lower conductors with both ends supported by brackets are arranged in the left-right direction, and these conductors are connected to a short-circuit detection device, and an alarm is connected to this short-circuit detection device.

According to this configuration, when the antenna of a car that is about to enter the parking lot is left out, the antenna comes into contact with both conductors and short-circuits before colliding with the height detection device, and the short-circuit is detected as a short-circuit. The device will detect this and activate the alarm.

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

A turntable 28 is provided on the first floor 5 near the entrance 27. A height detection device 29 is provided in the vehicle running section between the turntable 28 and the lift device 12. As shown in FIGS. 3 to 6, this height detection device 29 includes a gate-shaped frame 30 and a left-right shaft 32 rotatably attached to the beam portion of the frame 30 via a bearing 31. , a detection plate 34 attached to the shaft 32 via a plurality of adjustable rods 33 , a balance weight 35 attached to the shaft 32 on the opposite side of the detection plate 34 , and a balance weight 35 attached to the shaft 32 on the opposite side of the detection plate 34 . a cam body 37 fixed to one end and having a recess 36 at one location in the circumferential direction;
The frame body 30 comes into contact with the circumferential surface of the cam body 37.
The limit switch 38 attached to the side and the shaft 3
a stopped plate 40 fixed to the other end of the frame 30 and having a concave portion 39 at one location; a swinging plate 42 attached to the frame 30 via horizontal pins 41 so as to be able to swing vertically; It consists of a stopper body 43 that is attached to the tip of the plate 42 and can be freely engaged with and disengaged from the recess 39 from below, and a balance weight 44 that is attached to the rear end of the rocking plate 42 to bias the engagement. is connected to the control device.

As shown in FIGS. 3, 7, and 8, a pair of left and right brackets 4 are provided in front of the front side of the detection plate 34.
A pair of conductors (such as piano wire) 46, 4 through 5
7 are arranged in the left and right direction. That is, the conductor 46,
One end of 47 is connected to bracket 4 via holder 48.
5, and the other end is supported by a tension spring 4.
9, 50 and the bracket 45 via the holder 51.
Supported by Both conductors 46 and 47 are connected to the comparator 5
2, a resistor 53, a power source 54, and the like.The comparator 52 is connected to a short circuit detection device 55 including a resistor 53, a power source 54, etc., and an alarm 56 such as a buzzer is connected to the comparator 52.

In the multi-story parking lot with the above configuration, the parking work is as follows:
First, the lifting platform 16 is lowered by the lift device 12 so that the pallet 11 placed thereon is flush with the first floor floor surface, and then the car 24 is moved onto the pallet 11. When the vehicle is imported, if the vehicle height is within the height restriction range, the vehicle is imported as is without any detection. When the vehicle height is higher than the height limit, the vehicle 24 comes into contact with the detection plate 34, so that the shaft 32
rotates, and as a result, the operating portion of the limit switch 38 comes out of the recess 36 and corresponds to the large diameter portion, turning on, and it is thus detected that the height is above the height limit. After this detection, the car 24 moves to the pallet 11.
Populated above. At this time, the warehousing floor of the car 24 has been determined. That is, when the vehicle height is within the height restriction range, the vehicle is stored on the second floor 6 or the third floor 7, and when the vehicle height is above the height restriction range, the vehicle is stored on the fourth floor 8. 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. The movable bases 23A and 23B 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 a trolley 17. Next, the trolley 17 is driven and stopped opposite the target parking section 10, and a chain conveyor or the like is operated to enter the parking section 10.

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

For example, if the car 24 is within the height limit and the antenna protrudes beyond the height limit, this car 24
4, first, as shown by the imaginary line in FIG. 8, before the antenna 57 collides with the detection plate 34, it comes into contact between the two conductors 46 and 47, causing a short circuit, and the alarm 56 issues an alarm. Accordingly, the driver only has to move the antenna 57 back and forth.

Effects of the Invention According to the antenna detection device in a multi-story parking lot according to the present invention having the above configuration, when the antenna of a car about to enter the vehicle is left out, a pair of conductors is detected before the antenna collides with the height detection device. When the short circuit is detected by the short circuit detection device and the alarm is activated, the driver confirms the alarm and withdraws the antenna, causing the antenna to bend or break. You can make inventory without having to do anything.
