In ultra-high-speed buildings, etc., in order to improve the space efficiency of buildings, etc., double-deck elevators with two-tiered cars, upper and lower cars, are used for mass transportation as vertical means of transportation in buildings. It is often used for: In this double-deck elevator, occupants can get on and off at the same time from the upper and lower cars on the floors adjacent to each other. Therefore, the distance (car interval) between the upper and lower two-stage cars is made to match the inter-floor distance of the building where the elevator is installed.
[0003]
[Problems to be solved by the invention]
However, due to architectural errors in the building, the actual floor distance may be different from the floor distance at the time of design. In particular, there may be a large error in the floor-to-story distance before and after the resident starts living in the building because the load received by the beams of the building is different. If the floor distance differs from the design value in this way, the car floor positions of the two cars do not match the hall floor position, and a step is formed between the car floor and the hall floor. Then, there is a problem that the passenger cannot stably get on and off due to the step, etc.
[0004]
Accordingly, the present invention has been made to solve the above-described problem, and the height of the floor of the upper and lower cars can be made to coincide with the floor of the hall on the floor adjacent to the upper and lower sides, so that the occupant can smoothly move. The purpose of the present invention is to provide a double-deck elevator capable of easily getting on and off.
[0005]
[Means for Solving the Problems]
The present invention relates to a double-deck elevator provided with an upper car and a lower car in a vertical direction in a car frame body, and a car interval adjusting mechanism capable of shifting at least one of the upper car and the lower car in the vertical position. It is a double deck elevator characterized by having.
[0006]
In this double-deck elevator, the car interval between the upper car and the lower car can be shifted by the car interval adjusting mechanism, and can be adjusted to the floor distance of the hall. Therefore, the car floor height of the upper car and the lower car can be made to coincide with the hall floor of the floor adjacent to the upper and lower floors, and the occupant can get on and off smoothly.
[0007]

The car frame 2 is provided in the elevator hoistway 3 so as to be vertically movable while being guided by a guide rail (not shown). The upper end of the car frame 2 is connected to a hoist of an elevator elevating mechanism (not shown) via a cord a. The car frame 2 and the following cars 5 and 6 are moved up and down by the driving force of the elevator lifting mechanism (not shown).
[0010]
The car frame 2 includes a plurality of upright frames 2a extending in the vertical direction, a lower beam 2b fixed at a position below the plurality of upright frames 2a, and an upper beam 2c fixed at a position above the plurality of upright frames 2a. A main frame is composed of a middle beam 2d fixed at an intermediate position between the plurality of standing frames 2a and a floor support 2e fixed on the middle beam 2d. A lower car 5 is disposed between the middle beam 2d and the lower beam 2b in the car frame 2. The undercarriage car 5 is fixed to the car frame 2. An upper car 6 is disposed between the upper beam 2c and the middle beam 2d in the car frame 2. The upper car 6 is vertically movably supported by a car interval adjusting mechanism 10 installed on the floor receiving frame 2e.
[0011]
As shown in detail in FIGS. 2 and 3, the car interval adjusting mechanism 10 includes a handle 11 provided on the floor receiving frame 2 e, a gear group 12 rotated by rotating the handle 11, and a gear group 12.

Next, the operation of adjusting the interval between the upper car 6 and the lower car 5 to the interval between the upper and lower holes 20 and 21 will be described. The upper car 6 and the lower car 5 are stopped in the adjacent upper and lower halls 20, 21. Here, the stop position of the elevator is adjusted to a position where the height of the car floor 5a of the lower car 5 matches the height of the hall floor 21a of the lower hall 21.
[0014]
The worker moves to a space below the car floor 6a of the upper car 6 and rotates the handle 11 of the car interval adjusting mechanism 10. Then, by the rotation of the handle 11, the gear group 12 rotates in the order of the first hypoid gear 12a, the second hypoid gear 12b, the large diameter spur gear 12d, and the four small diameter spur gears 12e. The rotation of the four small-diameter spur gears 12e causes the four ball screws 13 to rotate synchronously, and the four vibration-proof rubber stands 14 to move in the vertical direction according to the screw pitch of the ball screws 13. The upper car 6 is displaced in the vertical direction by the movement of the four rubber stands 14, and the height of the car floor 6a of the upper car 6 is adjusted to the height of the hall floor 20a of the upper hall 20.
[0015]
As described above, in the double-deck elevator 1, the car interval between the upper car 6 and the lower car 5 can be shifted by the car interval adjusting mechanism 10, and can be adjusted to the distance between the halls. Therefore, the heights of the car floors 6a and 5a of the upper car 6 and the lower car 5 can be made to coincide with the hall floors 20a and 21a of the floors adjacent to each other vertically, and the occupants can get on and off smoothly.
[0016]

May be controlled to match the car interval adjusting mechanisms 10 and 10A. In this way, the car floor 6a of the upper car 6 can be automatically adjusted to the height of the hall floor 20a.
[0027]
In the above embodiments, the upper car 6 is moved vertically by the car interval adjusting mechanisms 10 and 10A. However, the lower car 5 may be moved. The car 6 and the lower car 5 may be configured to move together.
[0028]
In the above embodiments, the car interval adjusting mechanisms 10 and 10A are installed in the double deck elevator 1, but may be installed in the single deck elevator. When installed in a single-deck elevator, it simply functions as a car floor height adjustment mechanism, allowing fine adjustment of the car stop position.
[0029]
【The invention's effect】
As described above, according to the present invention, in a double-deck elevator provided with an upper car and a lower car in the vertical direction in the car frame, at least one of the upper and lower positions of the upper car and the lower car is set. Since there is a car interval adjusting mechanism capable of shifting, the car interval of the upper car and the lower car can be shifted by the car interval adjusting mechanism, and can be adjusted to the floor distance. Therefore, the car floor heights of the upper and lower cars can be made to coincide with the floors of the halls adjacent to the floor above and below, so that the occupants can get on and off smoothly.
