BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail lifting device, and more particularly to an elevator guide rail lifting device used when installing a guide rail.

0002

2. Description of the Related Art Conventionally, the present applicant has proposed an elevator guide rail lifting device used when installing a guide rail, as described in, for example, Japanese Patent Application Laid-Open No. 1-127587.

FIG. 5 is a perspective view showing this type of conventional guide rail lifting device, and FIG. 6 is a cross-sectional view showing a portion of an elevator hoistway. Generally, as shown in FIG. 6, in an elevator, car guide rails 4 and 5 are fixed to mutually opposing wall surfaces in a hoistway 1 via a pair of brackets 2 and 3, respectively. In this state, guide rails 4 and 5
are arranged vertically and face each other, and the car 10 moving up and down the hoistway 1 is guided by the guide rails 4 and 5. Similarly, counterweight guide rails 8 and 9 are fixed to other wall surfaces via a pair of brackets 6 and 7, respectively. In this state, the guide rails 8 and 9 are erected and are opposed to each other, so that the counterweight 11 moving up and down the hoistway 1 is guided by the guide rails 8 and 9. As shown in FIG. 5, the guide rail lifting device used when installing the guide rails 4, 5, 8, and 9 includes a first connecting member 12 that connects the car guide rails 4 and 5, and a counter. A second connecting member 13 that connects the weight guide rails 8 and 9, a third connecting member 14 that connects the first connecting member 12 and the second connecting member 13, and these connecting members 12 to 14. and a wire rope 15 for hoisting. Bolts 16 and 17 for fastening the guide rails 4 and 5, respectively, are screwed into both ends of the first connecting member 12, and similarly, the second connecting member 13
Bolts 18 and 19 for fastening the guide rails 8 and 9, respectively, are screwed into both ends of the guide rails 8 and 9, respectively. In the guide rail lifting device configured in this way, the guide rails 4, 5,
8 and 9, a first connecting member 12 is provided between the guide rails 4 and 5, and bolts 1 are attached to both ends of this connecting member 12.
By attaching the guide rails 4 and 5 via the guide rails 6 and 17, the distance between the guide rails 4 and 5 is maintained at a predetermined dimension, and similarly, the distance between the guide rails 8 and 9 is maintained at a predetermined dimension by the second connecting member 13. These connecting members 12, 1
3 is maintained at a predetermined dimension by the third connecting member 14. In this state, each of the guide rails 4, 5, 8, and 9 is erected sequentially from the bottom to the top by lifting the guide rails 4, 5, 8, and 9 via the wire rope 15 and the connecting members 12 to 14. This is designed to improve the efficiency of guide rail installation work.

0004

However, in the conventional elevator guide rail lifting device described above, the length dimension of the first connecting member 12 is set in advance according to the interval between the car guide rails 4 and 5. Therefore, if the spacing between the car guide rails is different from the above-mentioned spacing, the above-mentioned connecting member 12 cannot maintain the spacing between the car guide rails at a predetermined dimension, and the width of the car Cannot handle cases with different dimensions. Similarly, the second connecting member 13 cannot maintain the interval between the counterweight guide rails at a predetermined dimension, and cannot cope with cases where the width dimensions of the counterweights are different. Moreover, the third connecting member 14 cannot maintain the distance between the car guide rail and the counterweight guide rail at a predetermined dimension, and cannot cope with cases where the car depth dimension and the counterweight depth dimension are different. That is, when the outer dimensions of the car and the outer dimensions of the counterweight are different, there is a problem that this guide rail lifting device cannot be applied, and its versatility for various elevators is poor. In addition, when the external dimensions of the car and the external dimensions of the counterweight are different in this way, the above-mentioned guide rail lifting device cannot be applied, so it is necessary to provide another guide rail lifting device.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to provide an elevator guide that can be applied to various elevators having different outer dimensions of cars and outer dimensions of counterweights. An object of the present invention is to provide a rail lifting device.

[0006]

[Means for Solving the Problem] In order to achieve this object, the present invention provides a first connecting member that connects a pair of mutually opposing guide rails for a car, and a pair of counterweight guide rails that oppose each other. A guide rail for an elevator comprising: a second connecting member that connects the first connecting member and the second connecting member; and a cable body that lifts these connecting members. In the lifting device, at least one of the connecting members is provided with a holding means for holding the connecting member in an expandable and contractable manner.

[0007]

[Operation] Since the present invention is constructed as described above, for example, when the first connecting member, the second connecting member, and the third connecting member are all provided with holding means, the guide rail can be installed. At this time, after adjusting the length by expanding and contracting each of the connecting members described above according to the external dimensions of the car and the external dimensions of the counterweight, these connecting members are held by the holding means, and the guide rail is connected. Attach to the member, that is, maintain the distance between the car guide rails, the distance between the counterweight guide rails, and the distance between the car guide rail and the counterweight guide rail to predetermined dimensions, and then, The above-mentioned guide rail is lifted up by the cable body via the connecting member. This makes it possible to apply the present invention to various elevators having different outer dimensions of cars and outer dimensions of counterweights. It should be noted that the present invention can be applied to various elevators even if one or only two of the above-mentioned three connecting members are provided with holding means.
