Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide rail centering device for an elevator, which is suitable for positioning a guide rail in a hoistway during an elevator installation process.

[0002]

[Prior Art]

 Generally, when installing an elevator, it is necessary to set guide rails for cars and counterweights in parallel in the hoistway at a predetermined interval without twisting, and centering work is performed for that purpose.

As a conventional centering device used for such centering work, as described in Japanese Utility Model Laid-Open No. 57-196072, a pair of guides erected substantially in parallel in a temporarily fixed state. It is known that gripping means for gripping the rail are provided on both sides of the employment body. With this centering device, while holding the guide rail with the gripping means, the mark engraved on the employment main body is matched with the piano wire hung in the hoistway, so that it can be used for a car or a balance. The pair of guide rails for the weight can be centered at the same time.

[0004]

[Problems to be solved by the device]

 However, even if the conventional centering device described above is used, the same centering work must be repeated for each of the pair of main guide rails (for the car) and the pair of counterweight guide rails. Since it is necessary to consider the relative position between each main guide rail and each balance weight guide rail, and it is not easy to secure the centering accuracy, there is a problem that the centering work is complicated and takes a long time.

The present invention has been made in view of the present situation of such centering work, and an object thereof is to provide an elevator guide rail centering device capable of positioning each guide rail quickly and accurately. Especially.

[0006]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to provide a main rail employment which is provided with a first employment main body and first gripping means which is supported on both sides of the first employment main body and which holds a pair of main guide rails. And a second rail body for supporting the pair of counterweight guide rails, which are supported on both sides of the second main body, and are provided with a second gripping means for gripping the pair of counterweight rails. This is achieved by providing a pair of employment connection members that connect the main rail employment and the weight rail employment.

[0007]

[Action]

 According to the above means, the distance between the first employment body and the second employment body and the positional relationship between the first gripping means and the second gripping means can be maintained by the employment connecting member. The relative position between the main guide rail and the counterweight guide rail can be easily defined, so that the working time can be significantly shortened while ensuring good centering accuracy.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. Here, FIG. 1 is a plan view showing the centering device in use in the elevator hoistway.

In FIG. 1, in the hoistway 1, a pair of main guide rails 2a and 2b are provided via rail brackets 3a and 3b, and a pair of counterweight guide rails 2c are provided via rail brackets 3c and 3d. , 2d are erected in a temporarily fixed state, and after being permanently fixed, they are guided by these guide rails 2a to 2d and ascend / descend in a direction opposite to the unillustrated rider and counterweight. . The guide rail centering device used for centering the guide rails 2a to 2d has a main rail hire 4, a weight rail hire 5, both rail hires 4, 5 in a predetermined relative positional relationship. It is mainly composed of a pair of employment connection members 6 and 7 that are kept and connected.

The main rail hire 4 includes a first hiring body 8, first gripping means 9 fixed to both sides of the hiring body 8 for holding the main guide rails 2 a and 2 b, and also of the hiring body 8. It consists of a positioning plate 10 fixed to both sides and having a mark (not shown) engraved. On the other hand, the weight rail employment 5 includes a second employment body 11 and a balancing weight fixed to both sides of the employment body 11. Second gripping means 12 for gripping the guide rails 2c, 2d. Further, at both ends of the pair of employment connecting members 6 and 7, the employment main bodies 8 and 11 are detachably fixed using bolts and the like, and these employment connecting members 6 and 7 are mutually attached. By connecting the intersecting portions, the overall shape is X-shaped.

The gripping means 9 sandwiches the guide rails 2a or 2b between the holding metal fittings 9a and 9b and tightens the fixing bolts 9c to hold them. Similarly, the holding means 12 holds the holding metal fittings 9a and 9b. The guide rail 2c or 2d is sandwiched between 12a and 12b, and a fixing bolt 12c is tightened to sandwich the guide rail 2c or 2d.

The centering operation of the guide rails using such a centering device is generally performed as follows.

First, the worker attaches the gripping means 9 to the main guide rails 2a and 2b at the height of the rail brackets 3a to 3d and clamps the gripping means 9, and also attaches the gripping means 12 to the counterweight guide rails 2c and 2d. And pinch. Next, the rail brackets 3a to 3d are moved so that the markings of the positioning plate 10 are aligned with the piano wire 13 suspended from the top of the hoistway 1, so that the guide rails 2a to 2d are lifted and lowered. Correct the position in path 1. At this time, since the distance between the employment body 8 and the employment body 11 and the positional relationship between the gripping means 9 and the gripping means 12 are maintained by the employment connecting members 6 and 7, the relative positions of the respective guide rails 2a to 2d are determined. It can be easily defined. Therefore, by this centering work, the pair of main guide rails 2a, 2b and the pair of counterweight guide rails 2c, 2d can be positioned at the same time and with high accuracy, and thus, good centering accuracy can be achieved. The work time can be shortened significantly while ensuring it.

[0014]

[Effect of the device]

 As described above, according to the present invention, since the main rail hire and the weight rail hire are connected by the hiring connecting member, the main guide rail and the counterweight guide rail can be accurately positioned at the same time. It has the excellent effect that the centering work can be performed extremely quickly.
