Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals denote the same or corresponding parts.
Embodiment 1.
Fig. 1 is a front view showing a car before renewal according to embodiment 1 of the present invention is provided, and fig. 2 is a side view showing the car as viewed from line II of fig. 1.
A pair of left and right car frame pillars 2 are fixed to a car 1 of an elevator, and a pair of left and right upper beams 3, a car floor 4, and an existing mounting arm 5 are fixed to the car frame pillars 2. The door opening/closing device 6 is fixed to the existing mounting arm 5. At least one (2 in the illustrated example) door 7 is supported in a suspended manner on the door opening/closing device 6.
Next, a method of updating an elevator door according to embodiment 1 will be described. Fig. 3 is a diagram showing a connection state of the car frame column, the existing mounting arm, and the door opening/closing device before the renewal. Fig. 4 is a diagram of the same form as fig. 3 after update. Fig. 3 and 4 each show a state in which the right side portion of the figure is viewed from the direction of fig. 2, and each of fig. 3 and 4 shows a state in which the right side structure is viewed from arrows III and IV.
First, as shown in fig. 3, before the renewal, the existing attachment arm 5 is detachably fixed to the upper portion of the car frame column 2 extending in the vertical direction by using a coupling body 21 such as a bolt. It is assumed that the mounting arm 5 is fixed to extend in a direction intersecting the car frame column 2.
Further, the existing door opening/closing device 6 is detachably fixed to the end of the existing mounting arm 5 by using a coupling body 23 such as a pair of bolts. The existing door opening/closing device 6 is provided with a positioning bolt 25 for preventing the existing door opening/closing device 6 from falling down.
In such a conventional structure, the updating is performed as follows when the installation height of the door opening/closing device is different before and after the updating.
In short, the update includes: a step of detaching the existing door opening and closing device from the existing installation arm in a state of keeping the existing installation arm which is fixed on the car frame column and supports the existing door opening and closing device; and a step of supporting the new door opening and closing device on the upper part of the height adjusting bracket, wherein the lower part of the height adjusting bracket is fixed on the existing mounting arm. The above-described steps will be described in more detail below.
First, as shown in fig. 4, the existing door opening/closing device 6 is detached from the existing mounting arm 5, and the lower portion of the 1 st portion 27a of the height adjusting bracket 27 is fixed to the existing mounting arm 5 using the coupling body 23 such as a pair of bolts.
The 1 st portion 27a of the height adjustment bracket 27 extends upward from the existing attachment arm 5, and is configured to have a substantially L-shape in a plan view.
The 2 nd portion 27b of the height adjustment bracket 27 and the new door opening/closing device 10 are fixed to the upper portion of the 1 st portion 27a of the height adjustment bracket 27 using a coupling body 29 such as a pair of bolts.
The 2 nd portion 27b of the height adjustment bracket 27 is formed in a substantially L shape in the left side part of the drawing of fig. 4. The new door opening/closing device 10 is disposed on the 2 nd portion 27b of the height adjustment bracket 27 on the opposite side of the 1 st portion 27 a. In other words, the 1 st and 2 nd parts 27a and 27b of the height adjusting bracket 27 and the new door opening/closing device 10 are sequentially connected to the connecting body 29 so as to be integrated with each other.
Further, as in the case where the door opening/closing device 6 is already provided, the new door opening/closing device 10 is provided with a positioning bolt 31 for preventing the new door opening/closing device 10 from falling down.
According to embodiment 1 described above, when the mounting heights of the door opening and closing devices before and after the update are different, the mounting position of the new door opening and closing device can be moved only in the height direction by providing the height adjustment bracket between the existing mounting arm and the new door opening and closing device. Thus, the existing mounting arm can be used for updating, a new door opening and closing device with a mounting height different from that before updating can be mounted on the existing mounting arm, and the improvement of the operability and the sharing of the door opening and closing device with other models can be realized.
Further, the mounting position of the new door opening/closing device is changed only in the height direction from the mounting position of the existing door opening/closing device. Specifically, the mounting position of the lower connecting body 23 on the height adjustment bracket is different from the mounting position of the upper connecting body 29 on the height adjustment bracket only in the height direction, and is the same in the left-right direction (door opening/closing direction) and the front-back direction (direction perpendicular to both the door opening/closing direction and the height direction). In this regard, for example, unlike the case of embodiment 1, when a bracket having a different pitch between a pair of bolts is provided on the mounting arm side and the new door opening/closing device side, it is necessary to make the shape of the mounting piece on the new door opening/closing device side a special-purpose product for updating. In contrast, if the mounting position of the new door opening/closing device is changed only in the height direction from the mounting position of the existing door opening/closing device as in embodiment 1, it is not necessary to use a dedicated fixture for the new door opening/closing device, and it is very easy to facilitate the sharing of the door opening/closing device with another model.
While the present invention has been described in detail with reference to the preferred embodiments, it is obvious that various modifications can be made by those skilled in the art based on the basic technical ideas and teachings of the present invention.
