Abstract

PROBLEM TO BE SOLVED: To provide a one-shaft multi-car type elevator with a small minimum distance between cars and less restriction in the interval between the floors of stop stories. SOLUTION: The cars other than a car disposed at the lowest position and the car disposed just below these cars among a plurality of cars are designated as an upper car and a lower car. When the upper car stops by fully compressing a buffer installed in a hoistway on the outside of a projected surface of the lower car, the lower car stopped on the lowest story of the hoistway does not come in contact with the upper car.

Next, the operation will be described. In normal operation, the two cars are operated at an appropriate interval. Also,
For example, in the case of a rope-type one-shaft multi-car type elevator, when there is an abnormality such as when the rope is broken, the car is decelerated by the emergency stop and the operation control is performed so that the distance of the car running immediately below is always greater than the deceleration distance of the emergency stop Therefore, no collision between cars will occur. In the event that some abnormality occurs in the upper car and the two cars approach beyond the limit while the lower car stops on the lowest floor where the lower car operates, the lower car 6 of the upper car 2 presses the upper car shock absorber 4. The upper car 2 is decelerated at a predetermined deceleration to prevent collision between the cars. Since the lower car 3 and the upper car 4 do not contact each other, the safety of the passengers of the car can be ensured.

In a high-speed elevator, the deceleration distance of the emergency stop is long, and it is difficult to secure a sufficiently long distance between cars in terms of operating efficiency. In some cases, cars may collide with each other. In that case, the upper car 2 descends while being in contact with the lower car 3, and as shown in FIG.
Is compressed and stopped. The lower car 3 stops at the lowest floor level and passengers can move out of the car quickly and safely. Since a plurality of upper car shock absorbers 4 are arranged point-symmetrically with respect to the center of the upper car 2, when the upper car 2 compresses the upper car shock absorber 4, the upper car 2 tilts or the upper car shock absorber 4 tilts. No.

Next, the operation will be described. It is assumed that the lower car 3 has completely compressed the lower car shock absorber 5 and stopped due to some abnormal operation. In this state, it is also assumed that the upper car has been fully compressed and stopped in the same manner due to abnormal operation. At this time, if there is no gap between the upper car 2 and the lower car 3, the two cars collide and the lower car is fixed by the shock absorber,
The impact force may increase and affect passengers,
Bonito cage damage also occurs. This problem can be solved by disposing the shock absorbers so that the upper car 2 and the lower car 3 do not come into contact with each other as shown in FIG.

In the drawing, reference numeral 7 denotes a lower beam of a lower car which also serves as a shock absorber pressing member, and an upper car shock absorber 4 has a point on the upper surface of the lower beam of the lower car which is outside the projection plane of the car with respect to the center of the upper car. A plurality are arranged so as to be symmetrical. In addition, lower car shock absorber 5
Is installed in the pit at the bottom of the hoistway,
When the operation range of the lower car is limited above the middle floor of the building, a plurality of cars are arranged on the hoistway wall projection outside the projection plane of the car so as to be point-symmetric with respect to the center of the lower car 3. Of course, when installing the lower car shock absorber 5 in the pit at the bottom of the hoistway,
It may be located at the center of the lower car.

Next, the operation will be described. In normal operation, the two cars are operated at an appropriate interval, but if some abnormality occurs and the two cars approach beyond the limit, the upper car shock absorber 4 is moved to the lower beam 6 of the upper car 2. Presses down and decelerates the upper car 2 at a predetermined deceleration to prevent collision between the cars.

Further, when the upper car 2 approaches the lower car 3 and compresses the upper car shock absorber 4 by the lower beam 6 in a state where the lower car 3 completely compresses the lower car shock absorber 5 and stops, the lower beam 7 Receives an upward reaction force from the lower car shock absorber 5 and a downward reaction force from the upper car shock absorber 4, but the central axes of the lower car shock absorber 5 and the upper car shock absorber 4 coincide with each other. No bending stress occurs. For this reason, the required strength of the lower beam 7 can be reduced, and the moving part weight of the elevator system can be reduced.

Further, of the plurality of cars, a car other than the car arranged at the lowest position, and a car arranged immediately below the car are an upper car and a lower car, and the upper car is provided on the hoistway outside the projection plane of the lower car. When the shock absorber is fully compressed and stopped, the lower car and the upper car that have been completely compressed and stopped in the hoistway do not come in contact with each other, so that the lower car is buffered due to some abnormal operation. When the upper car is stopped by fully compressing the shock absorber due to abnormal operation, the upper car 2 and the lower car 3 are similarly stopped.
Since the two shock absorbers are arranged in a positional relationship such that the lower car and the upper car are not in contact with each other, the safety of the passengers of the car can be ensured.
