Description

[Detailed Description of the Invention] This invention relates to improvement of an elevator tension wheel. FIG. 1 is a plan view of a conventional elevator tension wheel. In Fig. 1, 1 is a counterweight, 2 is a guide rail for the counterweight, and 3 is a mounting bracket for a tension wheel that is attached to the guide rail 2 for the counterweight, the lower end of which is fixed to the elevator tension wheel 4. . 5 is a governor rope.

In the elevator tension wheel having the conventional structure as described above, the mounting angle θ of the tension wheel mounting bracket 3 attached to the counterweight guide rail 2 has to be changed for each customer's order, and the above-mentioned tension wheel mounting In order to obtain the optimum mounting angle θ for each customer's order, it was necessary to draw the fittings 3 each time and carefully manufacture the mounting fittings 3 for the tension wheel.

This invention was made based on the above-mentioned circumstances, and aims to provide an elevator tension wheel that can change the mounting angle of the mounting bracket of the elevator tension wheel attached to a guide rail.

Embodiments of the elevator tension wheel of this invention will be described below with reference to the drawings.

FIG. 2 is a plan view showing the configuration of one embodiment of the present invention. In the figure, the same parts as in FIG. 1 are designated by the same reference numerals, and the explanation thereof will be omitted, and the parts different from those in FIG. 1 will be described.

As is clear from comparing FIG. 2 with FIG. 1, in FIG. In addition, a threaded rod 6 is installed between the mounting bracket 3 and the tension wheel 4, and both ends of the rod 6 are screwed and fixed with nuts 7. By adjusting at a predetermined position, the mounting angle θ of the mounting bracket 3 to the guide rail 2 can be freely adjusted.

FIG. 3 is a plan view showing the structure of another embodiment of the elevator tension wheel of this invention. In the case of FIG. 3, instead of the threaded rod 6 in FIG. 2, a turnbuckle 8 is installed between the mounting bracket 3 and the tension wheel 4 as a mounting angle adjustment mechanism for the mounting bracket 3.
The same effects as in FIG. 2 can be obtained.

As described above, according to the elevator tension wheel of this invention, a mounting bracket adjustment mechanism such as a threaded rod and a nut or a turnbuckle is provided between the tension wheel mounting bracket and the elevator tension wheel, and the tension wheel mounting bracket Since the mounting angle θ to the guide rail can be changed arbitrarily, there is no longer a need to create manufacturing drawings for tension wheel mounting brackets for each customer's order and create a product for each order, as was the case in the past. ,
It can be applied to any order and only needs to be adjusted during installation. This eliminates the need for drawings for each order, making manufacturing easier and reducing costs.
