Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car frame having a floor, a vertical frame and an upper frame.

[0002]

2. Description of the Related Art FIGS. 4 and 5 are views for explaining a conventional elevator car frame. FIG. 4 is a perspective view and FIG. 5 is a front view.

Conventionally, an elevator car frame has, for example, as shown in these drawings, a floor 1 and a lower frame 2 forming a floor portion.
And a vertical frame 4 that is integrally provided at the lower end with a bracket 3 that is fastened to the lower frame 2 and that is provided in pairs on both sides of the lower frame 2, and an upper beam 5 that is connected to the upper part of these vertical frames 4. .. In addition,
Each of the above-mentioned vertical frames 4 is made of L-shaped steel arranged in parallel, and the upper frame 5 is made of, for example, C channels arranged in parallel. The floor 1 is placed on a vibration-proof rubber 6 provided on the lower frame 2. 7 is each vertical frame 4
Are tie rods for reinforcement arranged on both sides of. Reference numeral 8 denotes a bracket provided on the upper beam 5, to which one end of a wire rope 9 for raising and lowering is fixed.

[0004]

If the gap between the sill 10 installed on the floor 1 and the sill 11 at each landing hall is different from the standard size, it is necessary to adjust it so that it is within the standard size. .. When such adjustment is necessary, conventionally, the bolts at the fastening portions of the lower frame 2 and the bracket 3 are loosened and adjusted, or the guide shoe fastened to the lower side of the emergency stop device 12 fastened to the lower frame 2. The sill 10 is adjusted so that the sill 10 approaches the sill 11 or the sill 10 separates from the sill 11 by loosening the bolts at the connecting portion with. However, since the upper beam 5 is connected by the vertical frame 4 and the bracket 8, the floor 1 and the like swings in the left-right direction around the upper beam 5 portion when adjusted by the above method, and the floor 1 horizontally moves accordingly. The vertical frame of the vertical frame 4 may be out of alignment, or the entire frame of the car may be twisted. In addition, it is necessary to perform centering work to obtain a more troublesome horizontal level and vertical level. ..

The present invention has been made in view of the above-mentioned circumstances in the prior art, and an object of the present invention is to make an adjustment between sills while maintaining the levelness of the floor and the verticality of the vertical frame. It is to provide a car frame.

[0006]

In order to achieve this object, the present invention connects a floor portion, a pair of vertical frames standing on both sides of the floor portion, and an upper portion of these vertical frames. In an elevator car frame having an upper beam, a first elongated hole extending horizontally in the floor and the vertical frame, and movably fastened via a bolt inserted into the first elongated hole Means to
And a second horizontal extension of the upper beam and the vertical frame.
And at least one of means for movably fastening the bolt through the second long hole.

[0007]

If the gap between the floor sill and the building floor sill is different from the standard size, loosen the bolts inserted in the first slot, for example, and vertically through the first slot. It suffices to move the floor portion with respect to the frame. At this time, since the first elongated hole extends in the horizontal direction, the floor portion can be moved in the horizontal direction. The bolt may be fastened at the position where the desired gap is obtained. This makes it possible to adjust the sill while maintaining the levelness of the floor and the verticality of the vertical frame.

When the second elongated hole is provided, the bolt inserted in the second elongated hole is loosened instead of loosening the bolt inserted in the first elongated hole as described above. The sill gap can be adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator car frame of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a view showing a state before connection between an upper beam and a vertical frame corresponding to the direction of arrow b in FIG. 1, and FIG. It is a figure which shows the state before the connection of the upper beam and a vertical frame corresponding to the a direction arrow of FIG.

Of the reference numerals shown in FIGS. 1 to 3, those equivalent to those shown in FIGS. 4 and 5 are designated by the same reference numerals. That is, even in the embodiments shown in FIGS. 1 to 3, a floor portion including the floor 1 and the lower frame 2,
The vertical frame 4 having the bracket 3 and the upper beam 5 connected to the upper portion of the vertical frame 4 are provided.

In particular, in this embodiment, as shown in FIG. 1, the bracket 3 integrally provided on the vertical frame 4 is
A long hole 12 extending horizontally is formed, and the long hole 12 is formed.
A bolt 13 for fastening the bracket 3 and the lower frame 2 is inserted therein. Further, as shown in FIGS. 2 and 3, a plate 14 is integrally provided at an end portion of the upper beam 5, and the plate 14
1, a plate 15 is integrally provided on the vertical frame 4, a hole 17 into which the bolt 16 shown in FIG. 1 is inserted is formed in the plate 14, and a long hole 18 into which the bolt 16 is inserted is formed in the plate 15. Are formed so as to extend in the horizontal direction.

In the embodiment constructed as described above, as a result of the centering work of the car frame, there occurs a situation in which the gap between the sill 10 of the floor 1 and the sill 11 of the building is different from the standard size. In this case, for example, loosen the bolt 13 that fastens the bracket 3 and move the lower frame 2 toward the sill 11,
Alternatively, the bolt 13 may be moved in a direction away from the sill 11 and the bolt 13 may be tightened at a position where the sill gap has a reference dimension.
As a result, the sill gap can be easily set to the standard size, and since the floor 1 moves in the horizontal direction integrally with the lower frame 2, the levelness of the floor 1 is not affected, and the vertical length is also reduced. Since the frame 4 is not moved, the verticality of the vertical frame 4 is not affected, and therefore realignment of horizontality and verticality is not required.

If necessary, the bolt 16 may be loosened to move the vertical frame 4 horizontally with respect to the upper beam 5 to adjust the sill gap. Even in this case, the vertical degree of the vertical frame 4 and the horizontal degree of the floor 1 are not affected.

[0015]

According to the present invention, since it is configured as described above, it is possible to perform adjustment between sills while maintaining the levelness and verticality of the floor. There is no concern about the re-centering work after the adjustment, and the efficiency of the car frame centering work can be improved.
