Problems solved by technology

[0011] First, the weight and volume of the insulating transformer 103 are very large (for example, about 300 kg). If it is to be packed into the control panel 116, the components that constitute the control panel 116 also require very high strength and large volume. become bulky
[0012] Second, as the power supply of the main circuit, the insulating transformer 103 not only has a large capacity and volume, but also has a thick diameter of the connecting cable. Therefore, if the insulating transformer 103 is packed into the control panel 116, the insulating transformer 103 and its wiring materials will occupy the entire More than one-third of the disk space
However, at the same time, various control signal lines connected between the passenger car or the lobby of the elevator are drawn from the lower part of the control panel 116, and the signals flowing in the control signal lines may be affected by the connection cables and cause malfunctions.
[0014] Based on the above reasons, the structure in which the insulating transformer 103 is housed in the transformer box 115 which is provided separately from the control panel 116 has to be used, so one of the dimensions L1, L2, and L3 (in the example shown in FIG. L2) is too large, it is difficult to reduce the overall area of ​​the machine room

no. 1 Embodiment

[0041] Fig. 3 is an explanatory diagram showing the structure in which the main part of the first embodiment of the present invention, that is, the transformer box 115 is mounted on the base 119, Fig. 3A is a top view, and Fig. 3B is a front view. The base 119 is composed of an upper frame member 119a, a lower frame member 119b, and a pillar 119c, and a free space 119d is formed between the upper frame member 119a and the lower frame member 119b. The upper end of the transformer box 115 accommodating the insulating transformer 103 is mounted on the upper side frame member 119a through the mounting plate 123 and the bolt 124, and the middle part and the lower end part of the lower side forming the upper end part are suspended in the empty space 119d. .

[0042] Fig. 4 is a block diagram of the elevator (system) of this embodiment using the installation structure of the transformer box 115 shown in Fig. 3A and Fig. 3B. The difference between FIG. 4 and FIG. 1 is that the high-f...

no. 2 Embodiment

[0046] Fig. 6 is a plan view showing an arrangement of equipment inside a machine room of an elevator system according to a second embodiment of the present invention. The difference between Fig. 6 and Fig. 5 is that the primary side of the insulating transformer 103 is connected to the power circuit breaker 102 (main power supply side) in the distribution box 121 with the first cable part 125, and the secondary side of the insulating transformer 103 is connected to the The high-frequency suppression filter 104 (power conversion device side) in the control panel 116 is connected by a second cable member 126 (however, these cable members 125, 126 are only omitted in FIG. Furthermore, shielding material 127 is used on these cable parts 125,126.

[0047] The power conversion device 129 installed in the control panel 116 is a high-frequency generator, and interference signals caused by high frequencies and the like will affect the surroundings. On the other hand, since the transf...

Embodiment 3

[0050] FIG. 7 is a front view showing a structure in which a transformer box 115 , which is a main part of a third embodiment of the present invention, is mounted on a base 119 . The difference between FIG. 7 and FIG. 3 is that the power distribution box 121 equipped with the power circuit breaker 102 is installed on the upper side frame member 119a constituting the base 119 .

[0051] In the first and second embodiments, as shown in FIGS. 5 and 6 , the distribution box 121 is disposed adjacent to the control panel 116 . However, since this position is far away from the hoist 109, if an abnormality occurs during maintenance of the hoist 109 by the operator and the power supply needs to be cut off immediately, it takes extra time to cut off the power accordingly.

[0052] Therefore, in the third embodiment, the distribution box 121 is installed on the base 119 as described above, so that the operator can quickly cut off the power supply during the maintenance work, thereby impr...

Abstract

The invention provides a apparatus arrangement structure of the elevator machine room. A transformer box (115) in which an isolation transformer (103) is received is fixed at its upper end section to a frame member (119a) with a installation plate (123) and a bolt member (124), and an inter mediate section and a lower end section that are on the lower side than the upper end section are suspendedin an empty space (119d). This construction enables the dimension for securing a predetermined inspection space to be a minimum required dimension, and as a result, the area of a machine room can be made smaller than that of conventional ones.

Description

technical field [0001] The present invention relates to a structure for arranging equipment for operating a hoist (lifting device) in a machine room of an elevator, and in particular relates to a machine room equipment arrangement structure of an elevator that effectively utilizes the space inside the machine room to realize miniaturization of the machine room. Background technique [0002] In the past, almost all elevators had a machine room. Recently, however, from the viewpoint of effectively utilizing the space in a building, among low-speed and small-capacity elevators, machine-room-less elevators that do not require a machine room have become mainstream. [0003] On the other hand, high-speed, large-capacity elevators still use machine room-equipped elevators. This machine room is a dedicated installation space for elevator components installed on the uppermost floor of the building, and hoisting machines and control panels are installed inside. bulletin. [0004] F...
