Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention accommodates a transverse truck in each parking section formed in multiple stages along a hoistway in which an elevator pallet platform ascends and descends. In an elevator type parking system in which cars are transferred between the pallet platform and the traversing truck, accidents caused by abnormalities of the parked vehicle, such as the impact opening of the car door and the impact opening of the back door during driving, can be avoided. This relates to a safety device designed to prevent such occurrences.

(Prior Art) The above-mentioned type of elevator-type parking device includes, for example, a system in which the front wheels and rear wheels of a car are placed on a fork-shaped pallet stand of an elevator, and one suspension or drive is carried out simultaneously at the same height and synchronously. It is equipped with a fork member consisting of four independent comb-like arms and a lock-like arm that are raised and lowered by a chain, and each of these fork members connects to an inner guide rail installed on both sides of the hoistway. It is configured to move up and down while being guided by parallel outer guide rails.

(Problem to be Solved by the Invention) However, one of the accidents that occur in the above-mentioned elevator parking system is when the door of a car is opened due to an impact while the elevator carrying a car is operating up or down. In many cases, this type of accident not only damages the vehicle, but also damages the frame of the parking device, causing serious damage.

In addition, when passing a car between the elevator's fork-shaped pallet platform and the transverse fork truck and entering the warehouse, it is necessary to check whether the car is over the height or the back door is open, otherwise the car will enter and exit the warehouse smoothly. Failure to carry out these checks may lead to unexpected accidents.

The purpose of the present invention is to check the height of a car in advance while going up and down in an elevator or when handing over a car.

(Function) In FIG. 1, since the left and right parking spaces 3 are the same, only the right side will be explained. In order to park the car 2, the elevator drive mechanism 9 is activated in advance to move the fork-shaped pallet of the elevator 5. The stand 11 is set at the lowest position, that is, the waiting position for warehousing.

When the automobile 2 moves forward and rides on the fork-shaped pallet platform, the elevator or the automobile pallet platform is raised by driving the elevator drive mechanism. In this case, the frame elevating drive mechanism 40 is activated in advance. Each detection bar 55 with a tape switch, which forms the detection frame by operating to bring the detection frame 41 into the raised position, is connected to a fixed tape installed in each parking lot 3.
It occupies the inner lower position of the ring 7.

In this state, the detection frame 41 is lowered in advance, and the elevator 5 is lowered and the fork-shaped pallet stand 11 is lowered.
When the door of the automobile 2 placed in the elevator is opened, the door touches any of the horizontal detection bars 55 with tape switches of the detection frame 41, so that the elevator drive mechanism 9 is operated and the elevator drive mechanism 9 is activated. The system is designed to prevent accidents by bringing the elevator to an emergency stop. Next, do you manually completely lock the door opening of the automobile 2?

Alternatively, if the car 2 is normally loaded on the fork-shaped pallet stand 11 of the elevator 5 without the doors being open from the time of parking, the pallet stand may be moved to a predetermined parking area 3 (the 4th floor in the illustration) and then The fork carriage 6 is raised to a height where it can ride on the underside of the pallet stand and then stopped.

Next, as shown in FIG. 2, the frame elevating drive mechanism 40
When the detection frame 41 is raised to the solid line position, if the height of the car 2 is over or the back door is open, the horizontal detection bar 55 with tape switch of the detection frame or the base of the tape switch is detected. In order to touch either or both of the bars 56 and 57, the second sensor 61 of the frame lifting/lowering drive mechanism 40 is activated to emergency stop the lowering of the detection frame to prevent an accident. It has become.

On the other hand, in order to store a car 2 that can be parked in a predetermined parking section 3 without detecting over-height or opening of the back door by the tape switch-equipped horizontal detection bar 55 and the tape switch base detection bar 56, 57, it is necessary to When the trolley traverse mechanism 26 is activated to cause the traverse fork trolley 6 to traverse in the direction of the arrow, the traversal fork trolley travels on the fixed rail 7, moves onto the fixed rail 8 of the hoistway 4, and moves to the fork-shaped pallet.

Next, when the elevator 5 is operated to lower the fork-shaped pallet stand 11, the fork members 11a, llb:llc on which the automobile 2 is placed.

Lid comb-like arms 35a, 35b: 35c.

35d is a comb-like arm 23°24 of the transverse fork carriage 6
At the same time as passing through, the automobile 2 is transferred to these comb-like arms, that is, the transverse fork truck 6. Subsequently, when the elevator 5 operates, the fork-shaped pallet platform 11 descends and reaches the lowest position, and the transverse fork carriage 6 on which the automobile 2 is placed is pulled in the direction of arrow B by the operation of the transverse mechanism 26.

The vehicle reaches the fixed rail 7 and is allowed to enter the parking section 3.

In addition, when leaving the car 2, it is sufficient to perform the operation in the opposite direction to that when entering the car.In addition, in the operation process described above, while the elevator 5 is going up and down, the horizontal detection bar 55 with a tape switch is lowered in advance. In this state, door opening is detected, but opening of the back door is not detected.

Furthermore, when the horizontal detection bar 55 with a tape switch is normally stopped, the second sensor 61 is used, and in the case of an abnormality, when the second sensor 61 detects or does not detect it, the first sensor
The sensor 60 is used to stop the horizontal detection bar with a tape switch, and for this purpose, the first sensor 60
Since it is necessary to sense or detect it later than the second sensor 61, it is necessary to set Ω and 〉ρ2.6 (Effects of the Invention) The present invention is configured as described above.

This produces the effects described below.

(1) On both sides of the elevator hoistway, a detection frame with the function of detecting the opening of a car door is installed so that it can be moved up and down, so that when a car placed in the elevator opens its door. - The detection frame detects the opening of the door and stops the drive of the elevator drive mechanism, and the elevator ascent and descent is brought to an emergency stop, thereby preventing the occurrence of an accident.

(2) On both sides of the elevator hoistway, a detection frame is provided that can move up and down and has the function of detecting whether the height of the car is over or the back door is opened. When the vehicle exceeds the height or the back door is opened, the detection frame detects the height exceeds or the back door is opened, and stops driving the frame lifting/lowering drive mechanism, and the movement of the traversing trolley comes to an emergency stop to prevent an accident from occurring. This can be prevented.
