Description

Description: FIELD OF THE INVENTION The present invention relates to a guide rail centering device for an elevator.

[Background of the Invention]

Recently, as disclosed in JP-A-55-48182 as an elevator installation method, the floor plate of the elevator car is moved by a permanently installed traction machine, and a worker rides on the floor plate of the car. A new type of equipment has been developed to perform work such as entrance and exit sill, three-way frame, wiring, and piping. Actually used as an elevator guide rail centering device by this method Sho 57-19607
No. 2 publication is proposed.

However, as shown in FIGS. 3 and 4, this device has a mounting mechanism for the device when the clearance dimension 1,1 ′ between the hoistway walls 8,8 ′ and the guide rails 1,1 ′ is small. Engagements 16,1
There is a problem that the 6'tightening handles 17, 17 'interfere with the hoistway walls 8, 8', and the centering device cannot be mounted on the guide rails 1, 1 '. Further, the riding comfort of the elevator is greatly affected by the degree of opposition α ° (shown in FIG. 4) called twist of the guide rails 1, 1 ′. Therefore, in order to measure this twist, it is necessary to provide special devices 10 and 11, and there is a drawback that it is troublesome to correct this due to the occurrence of twist.

In addition, 2,2 'are piano wires for centering, 3 is a main frame of the centering device, 4 and 4'are ruler plates fixed to both ends of the main rod 3, and 10
Is a measuring line connecting the fixed points on the ruler plates 4 and 4'at both ends, and 11 is a scale plate which projects in the middle of the longitudinal direction of the main rod 3 and shows the amount of twist.

[Object of the Invention]

An object of the present invention is to provide a guide rail centering device for an elevator, which is easy to perform centering operation and can be mounted on a guide rail without causing twisting.

[Outline of Invention]

The feature of the present invention is that the main rod (3) and a ruler plate fixed to the end of the main rod (3) and having a mechanism for holding the guide rail (1) and a notch for fitting with the centering piano wire. In the elevator guide rail centering device including (4), the ruler plate (4) has a surface (4a) in contact with one side surface of the guide rail (1) and a surface (4e) in contact with the tip surface. In addition, a shape corresponding to the horizontal cross section of the guide portion (1a) of the guide rail (1) is cut out, and as a result, a stopper (4b) is formed and a connecting bolt (5) is formed on the stopper (4b). A pressing plate (6) is attached so that it can be tightened and loosened by means of the surface (4a) of the ruler plate (4) and the pressing plate (6) to hold the guide rail (1). Especially.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In these figures, 5 and 5'are connecting bolts corresponding to the screw rods 15 and 15 'shown in FIGS. 3 and 4, and 6 and 6'are the engaging elements 16 shown in FIGS. It is a pressing plate corresponding to 16 '.

The ruler plates 4 and 4 ′ have surfaces 4a and 4a ′ that come into contact with one surface of the guide rails 1 and 1 ′, and the guide portion 1 of the guide rails 1 and 1 ′.
The cutouts have a shape substantially corresponding to the horizontal cross section of a, 1a ', and as a result, stoppers 4b, 4b' are formed. Also,
The ruler plates 4 and 4'are cutouts 4c and 4 that fit the piano wires 2 and 2 '.
It has c ′ and indices 4d, 4d ′.

When centering the guide rails 1 and 1 ′, first, on one side surface of the guide rails 1 and 1 ′ that are separated from each other and are erected in parallel, the surfaces 4a and 4a ′ of the ruler plates 4 and 4 ′, Guide rail 1,
Make sure that surfaces 4e and 4e 'are in contact with the tip surface of 1',
Next, on the other side of the guide rails 1, 1 ',
6a, 6a 'is applied and the handle 17, 17' is rotated to screw in the connecting bolts 5, 5 ', and the pressing plates 6, 6'are attached to the ruler plate 4,
Tighten and fix to 4 '. This allows the guide rail
The guide portions 1a, 1a 'of 1, 1'are clamped and held by the surfaces 4a, 4a' of the ruler plates 4, 4'and the surfaces 6a, 6a 'of the pressing plates 6, 6'.

After mounting the centering device on the guide rails 1, 1'in such a state, the indicators 4d, 4d 'of the notches 4c, 4c' of the ruler plates 4, 4 '.
Perform centering by moving the centering device together with the guide rails 1 and 1'to fit the piano wires 2, 2 '.

According to the embodiment thus constructed, the ruler plate 4 and the ruler plate 4'are connected by the main rod 3 in parallel and at right angles, so that the guide rails 1, 1'are in a twist-free state.
Therefore, it is not necessary to measure the twist using a special device. Further, since the guide rail centering device can be gripped by the guide rails 1 and 1'without interfering with the hoistway walls 8 and 8 ', even if the inner dimension of the hoistway is minimized, the guide rail 1 can be easily held. , 1'can be erected at a predetermined position. As a result, the centering work efficiency of the guide rail can be improved, and accordingly, the installation work efficiency of the elevator can be improved.

〔The invention's effect〕

ADVANTAGE OF THE INVENTION According to this invention, the operation | movement at the time of centering is easy, moreover, it can be attached to a guide rail without causing a twist to a guide rail without producing a twist, and centering work of a guide rail compared with the past. There is an effect that the efficiency can be improved and the installation work efficiency of the elevator can be improved accordingly.
