Problems solved by technology

[0008] However, although the existing machine-room-less elevator has the above-mentioned advantages, on the other hand, there is the following problem: because the rail supports the load of the elevator, the size of the rail becomes larger, and when the lifting stroke becomes higher, the corresponding The track accounts for a large proportion of the cost of the elevator, which is the main reason for the high cost

Embodiment approach 1

[0022] figure 1 It is a top view of the machine-room-less elevator of Embodiment 1, figure 2 It is a diagram schematically showing the relationship between the car and the beam of the machine-room-less elevator according to the first embodiment. image 3 is shown from figure 1 A diagram of the state of the main structural elements of the machine room-less elevator observed in the transverse direction (arrow III).

[0023] The elevator has a car 5 moving up and down in a shaft defined by a shaft wall 10 , a counterweight 14 , a pair of left and right car guide rails 15 , and a pair of left and right counterweight guide rails 16 . The left and right pair of car guide rails 15 and the left and right pair of reusable guide rails 16 respectively extend up and down in the hoistway. In the first embodiment of the counterweight rear type, the counterweight 14 is arranged behind the car 5 (on the opposite side of the landing) in plan view.

[0024] The car 5 is disposed between a ...

Embodiment approach 2

[0036] Next, based on Figure 4 Embodiment 2 of the present invention will be described. Figure 4 It is about this embodiment 2 and image 3 Figures in the same way. In addition, this Embodiment 2 is the same as the said Embodiment 1 except the part demonstrated below.

[0037] In Embodiment 2, the arrangement of the hoisting machine and the car-side return sheave in the configuration of Embodiment 1 is replaced. That is, the hoisting machine 6 in Embodiment 2 is installed on the first supporting beam portion 1 , and the car-side return sheave 12 is installed on one beam member of the third supporting beam portion 3 .

[0038] Also in the second embodiment configured in this way, the same advantages as those in the first embodiment described above are obtained. Moreover, in this Embodiment 2, compared with the case where a traction machine is installed in the 3rd support beam part, there exists an advantage that the maintenance space of a traction machine can be ensured e...

Embodiment approach 3

[0040] Next, based on Figure 5 and Figure 6 Embodiment 3 of the present invention will be described. Figure 5 and Figure 6 Respectively about this Embodiment 3 and figure 1 and image 3 Figures in the same way. In addition, this Embodiment 3 is the same as the said Embodiment 1 except the part demonstrated below.

[0041] In Embodiment 1 of the side-positioned counterweight type, the counterweight 14 is arranged on the side of the car 5 in plan view, and the return sheave is not required. Above the uppermost floor beam 4 are provided a first support beam portion 101 , a second support beam portion 102 , and a third support beam portion 103 .

[0042] The first support beam portion 101 includes a pair of beam members extending horizontally and on the same straight line. The first support beam portion 101 does not extend continuously in a manner spanning between the pair of beam members of the uppermost floor beam 4 , but the pair of beam members of the first support ...

Abstract

A machine room-less elevator is provided with: a car (5) ascending and descending within a hoistway of a building; a counterbalance weight (14) ascending and descending in the direction opposite the direction of movement of the car; a rope (7) for suspending the car and the counterbalance weight; and a hoist (6) for driving the rope. A support beam which does not support the load of the building but supports the load of at least the car, the counterbalance weight, the rope, and the hoist is supported by a floor beam (4) of the uppermost story of the building.

Description

technical field [0001] The present invention relates to machine room-less elevators. Background technique [0002] For example, as disclosed in Patent Document 1, in an elevator hoistway, a car and a counterweight are installed so as to be able to move up and down. These cars and counterweights are suspended on ropes driven by traction machines. Furthermore, by driving the ropes by the traction machine, the car and the counterweight move up and down in directions opposite to each other. [0003] In addition, most machine-room-less elevators make the rails support the load of the elevator. By making the rails support the load of the elevator, it becomes a structure that does not depend on the building side as much as possible, so there are few requirements for the building structure at the design stage (study on the position of the beam bearing the load, etc.) (short design time), and more The advantage of using the track as a reference point to accurately find the locatio...
