DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car frame of an elevator, and more particularly to a car frame of an elevator suitable for installing a guide rail erected in a hoistway.

[0002]

2. Description of the Related Art Generally, installation of a guide rail using a car of an elevator has been performed by using a car frame having a structure as shown in FIG.

FIG. 4 is a perspective view showing a car frame used for installation work of a general guide rail.

As shown in FIG. 4, a car frame 1 is a vertical frame 4 having a pair of two long members 4a and 4b facing each other with one guide rail 3 established in a hoistway 2 therebetween. When,
It has a car floor 5 supported by the lower part of the vertical frame 4 and an upper frame 6 whose both ends are connected to the upper part of the vertical frame 4. A supported work floor 7 on the car is provided.

In the car frame 1 configured as described above, an operator rides on the work floor 7 on the car, and performs centering and fixing of the guide rails by using the centering device 8.

[0006] However, in the above-described system, the work floor 7
Is a temporary member used only during installation work,
The production cost of this temporary member, or the work of mounting and removing it, required a problem in terms of cost or efficiency.

[0007] In order to solve this problem, there has been conventionally proposed an operation for installing the guide rails 3 from the car floor 5.

FIG. 5 is a plan view showing a main part of a conventional guide rail installation apparatus.

As shown in FIG. 5, the conventional guide rail installation apparatus has a fixture 10 for centering and fixing the guide rail 3 to the hoistway wall 2a, and the fixture 10 is moved up and down by anchor bolts 10a. It is configured to be fixed to the road wall 2a.

[0010] As this type of guide rail installation apparatus, for example, one described in JP-A-5-278968 can be mentioned.

[0011]

In the above-described conventional guide rail installation apparatus, when fixing the fixture 10 to the hoistway wall 2a with the anchor bolts 10a, first,
A driving hole (not shown) for driving the anchor bolt 10a to the hoistway wall 2a must be provided. However, FIG.
As shown in FIG. 5, when the driving hole is to be opened from the car floor 5, the vertical frame 4, that is, the long members 4a and 4b is located at a position facing the driving position. I couldn't do the drilling work. As a result, the fixture 10 cannot be fixed to the hoistway wall 2a, and therefore, the work of installing the guide rails 3 from the car floor 5 has not been realized. In addition, there is also a method of narrowing the long members 4a and 4b if only the boring operation is performed. However, there is also a problem that if the width is reduced, the long members 4a and 4b become obstacles and the centering device 8 of the guide rail 3 cannot be used.

The present invention has been made in view of such a situation in the prior art, and has as its object to perform an operation of setting anchor bolts for fixing a fixing tool from a car floor and an operation of centering a guide rail. The purpose of the present invention is to provide an elevator car frame that can be used.

[0013]

SUMMARY OF THE INVENTION To achieve this object, the present invention provides a pair of guide rails erected in a hoistway.
Two elongated members mutually have either toward one another by interposing the respective
A pair of vertical frames consisting, these and your floor or vertical frame is supported on the bottom, in the car frame of the elevator and a upper frame whose opposite ends are connected to the vertical frame top, front Sulfur butterfly elongate member
Of the guide rail and a straight line connecting the pair of guide rails
From the car floor side and the upper frame side,
A piece extending toward the idrail side and one of these pieces
From the part located on the side close to the cage frame side end,
Extending in the direction of the rail so as to be substantially orthogonal to the straight line.
A member having a substantially L-shaped cross section having another piece
The distance between the piece of two elongate members which are opposed to each other,
The guide rail is configured to be wider than a width of a fixture for fixing the guide rail at a predetermined position of the hoistway.

According to the present invention configured as described above, when drilling a hole for the anchor bolt for fixing the fixture,
Since the interval between the two long members is set to be wider than the width of the fixing tool, the long members do not come to a position facing the driving position and do not hinder the driving operation. In the centering work, the guide rail can be gripped from between the long members. Thus, it is possible to perform the work of setting the anchor bolts for fixing the fixture from above the car floor and the work of centering the guide rail using the centering device.
