Abstract

PURPOSE:To restrain the height of a cage frame by providing guide shoes on both sides of an upper beam laid between the upper parts of vertical frames so that the guide shoes are located below the upper surface of the upper beam. CONSTITUTION:Upstanding surfaces having a U-like cross-sectional shape of a plurality of upper beams 6 laid between the upper parts of vertical beams 4 face with each other, and guide shoe attaching plates 7 are laid between the upper surface and parts of the plurality of beams 6 by means of fasteners. A recess 7a fitted on a T-like guide rail with a gap therebetween is formed in each of the attaching plate 7. A guide shoe 8 located below the upper surface of each beam 7 is formed therein with a recess 8a fitted on the guide rail, and are located between the beams 6, and further, it is positioned in a recessed space in the upper part of each vertical frame 4. In this way, since the guide shoe attaching plate 7 having the recess 7a is laid between the end parts of the upper beams 6 and since the guide shoe 8 located in the recessed space in the upper part of the vertical frame 4 is attached to the lower surface of the attaching plate 7, it is possible to restrain the height of a cage frame.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement C of the structure of an elevator car frame.

(Prior Art) Figures 3 and 4 show the car frame of a conventional elevator. In the figure, (1) is the lower frame, and the car floor (2) is placed on the lower frame (1). The car compartment (2) is placed on the car floor (2).
3), and vertical frames (4) each having a concave cross section are erected at both ends of the lower frame (1). (5) are guide shoes arranged at both ends of the bottom surface of the bottom frame (1),
(6) serves to vertically guide the car frame, in other words, the car compartment (3), along guide rails (not shown), and (6) is a plurality of upper beams installed horizontally between the upper parts of the vertical frames (4). The plurality of upper beams (6) each have a concave cross section and face each other, and a guide shoe mounting plate (7) is connected between both ends of the plurality of upper beams (6) via a fastener. ) is being constructed. (8) is a guide shoe attached to this guide shoe mounting plate (7) via a fastener, and has the same function as the guide shoe (5). ) is attached via a fastener to the oil supply device (9), and this oil supply device (9) supplies lubricating oil to the recessed part of the guide shoe (8) and the fitting part of the T-shaped guide rail (not shown). It functions to facilitate vertical sliding movement of the car frame, or in other words, the car compartment (3).

Furthermore, as a prior art document of this kind, Utility Model Application Publication No. 59-1597
No., Utility Model Application Publication No. 59-15867, etc.

(II!!I) By the way, if the space required at the top of the hoistway is small, it will be difficult to store the elevator car (3), so it is necessary to compress the height of the car frame. However, in the conventional elevator car frame, the guide shoe (8) was installed via the C guide shoe mounting plate (7) on the upper surface of the upper beam (6), so it was difficult to suppress the height of the car. I couldn't do it.

The present invention was developed in view of the above points, and an object of the present invention is to provide an elevator car frame that significantly suppresses the height of the car.

(Means for Solving Problem 1111) In order to achieve the above-mentioned object, in the present invention, vertical frames are erected on both sides of the lower frame provided with the elevator car, and between the upper parts of the vertical frames there is a The structure is characterized in that guide shoes are provided at both ends of the upper beam and are located below the upper surface of the upper beam.

(Function) According to the present invention, vertical frames are erected on both sides of the lower frame provided with the elevator cab, and an upper beam is installed between the upper parts of the vertical frames, and the upper beam is provided at both ends of the upper beam. Since the guide shoes are arranged below the upper surface of the upper beam, the height of the car frame can be significantly reduced.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in FIGS. 1 and 2. In the figure, (4) is a vertical frame with a concave cross section,
) are a plurality of upper beams installed horizontally between the upper parts of the vertical frames (4), and the vertical parts of the upper beams (6), which have concave cross-sections, face each other as shown in Figure 2. Cage and multiple upper beams (6)
As shown in FIG. 2, the distance C between the upper surface ends of the guide shoe mounting plate (A) is such that the guide shoe mounting plate (A) has a T-shaped guide rail ( (not shown)
A recessed portion (7a) is cut out to fit through the gap.

(8) is a guide shoe attached to the lower surface of the guide shoe mounting plate (A) via a fastener, and the guide shoe (8) located below the upper surface of this upper beam (6) is a guide rail fitting. As shown in FIGS. 1 and 2, the recess (8a) is located between the upper beams (6) and (6), and is disposed in the recessed space above the vertical frame (4). However, (9
) is a lubricant mounted heavily on the guide shoe mounting plate (7), and this lubricant amount 0) is provided with a recess (9) that fits into the guide rail with a gap between the guide shoe (8) and the guide. Its function is to supply lubricating oil to the fitting parts of the rails to ensure smooth sliding movement of the car frame.

As described above, according to the present invention, the guide shoe mounting plate (7) having the recess (7a) is installed between the ends of the plurality of upper beams (6), and the lower surface of the guide shoe mounting plate (7) There is a guide shoe (8) located in the recessed space at the top of the vertical frame (4).
Since the height of the C1 car frame can be significantly reduced by comparing FIGS. 1 and 4, it is possible to significantly reduce the height of the C1 car frame.

(Effects of the Invention) As described above, according to the present invention, since guide shoes are provided at both ends of the upper beam and are located below the upper surface of the upper beam, the height of the car frame is significantly reduced. We can provide elevator car frames that can be used.
