DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a counter rail centering device for an elevator for centering a counterweight guide rail, that is, a counter rail.

[0002]

2. Description of the Related Art FIG. 7 is a perspective view of an elevator equipped with a conventional counter rail centering device, and FIG. 8 is a plan view of an elevator equipped with a conventional counter rail centering device.

Generally, in an elevator, as shown in FIG. 7, a pair of guide rails 3 for guiding a car 2 and a pair of counter rails 4 for guiding a counterweight (not shown) are provided in a hoistway 1. Have been. The car 2 has a car floor 6 and an upper frame 7 each having a guide shoe 5 at each end which engages with a pair of guide rails 3.
, A pair of car vertical frames 8 connecting the car floor 6 and the upper frame 7, a handrail 9 fixed to an intermediate portion of the pair of car vertical frames 8, and fixed to an upper portion of the car vertical frame 8. A protective ceiling (not shown) is provided.

A counter rail centering device 20 shown in FIG. 7 includes a grip 21 for gripping a pair of counter rails 4 and a base 22 to which the grips 21 are attached at a predetermined interval. I have.

In the conventional counter rail centering device 20 configured as described above, when centering the pair of counter rails 4, first, the guide rails 3 and the counter rails 4 are temporarily installed in the hoistway 1, and then the guide rails are aligned. The car 2 is assembled while being engaged with the rail 3, and a counterweight (not shown) is assembled while being engaged with the counter rail 4, and then the car 2 and the counterweight are connected via a rope (not shown). In the hoistway 1, it is suspended in a so-called slipper type.

[0006] Next, as shown in FIG.
The counter rail 4 is gripped by the back contact member 35 and the guide surface contact member 36, and the other grip portion 2
The other counter rail 4 is gripped by the second rear contact member 35a and the guide surface contact member 36a. Then base body 2
The distance between the indices 24 and 25 of the third guide rail 3 to the one guide rail 3 is a predetermined dimension, and the distance F from the other index 26 to the other guide rail 3 is a predetermined dimension. Is performed, the pair of counter rails 4 gripped by the grip portions 21 and 22 also move integrally, so that the pair of counter rails 4 is centered.

Alternatively, the extension line 38 from the index 24 of the base body 23 is matched with a reference position previously set at a predetermined location, for example, a centering reference line 37 provided on the car floor 6 shown in FIG. There is also a method of positioning the base body 23 so that the distance C from the end of the floor 6 becomes a predetermined dimension.

[0008] As related to this kind of prior art, there is, for example, one disclosed in Japanese Patent Application Laid-Open No. 10-36036.

[0009]

By the way, in the conventional counter rail centering device 20 described above, the base member 23 is provided.
Counter rail 4 based on the indexes 24, 25 and 26 of
When the centering is performed, the distances D, E, and F to the counter rails 3 and 4 are relatively large, and the indices 24-26 are minute, so that the distances D, E, and F are difficult to measure.
The measurement value differs depending on each operator, which affects the installation accuracy of the counter rail 4, and the measurement needs to be performed by a plurality of operators, resulting in poor workability.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances in the prior art, and has as its object to center an elevator counter rail in which a guide rail for a counterweight can be accurately set in a short time. It is to provide a device.

[0011]

In order to achieve the above object, the present invention provides a car having a car floor attached to a lower portion of a car vertical frame and a handrail attached to an intermediate portion of the car vertical frame. A counter rail core for an elevator, comprising: a base body provided on the handrail; and a gripper mounted on the base body at a predetermined interval and gripping a pair of counterrails for guiding a counterweight. In the feeding device, the base body is fixed to the car floor via the handrail, and a positioning index is provided on the car floor, and the positioning of the grip portion is performed based on the index, whereby the pair The counter rail is centered.

In the present invention constructed as described above, the base body is fixed to the car floor via a handrail, and a pair of gripping portions are mounted on the base body, and a pair of counter rails are respectively formed by the gripping portions. In the gripped state, the grip is positioned with reference to the car floor positioning index, and the pair of counter rails are centered. Thereby, the centering work of the counter rail can be performed accurately in a short time.
