Description

  The present invention relates to a method for installing a shared bracket device for an elevator.

  Generally, the elevator for observation and the elevator with a trunk take a so-called counterweight that falls off in a direction in which a counterweight runs in a direction orthogonal to the direction of the front of the car.

  And in the above-described method of making the counterweight fall sideways, a main bracket member for fixing a car guide rail for guiding the raising and lowering of the car, and the counterweight that is connected via the car and the rope and lifts up and down like a fishing bottle. It is common to adopt a common bracket structure in which a counter bracket member for fixing a counterweight guide rail that guides lifting and lowering is integrally connected.

  In the conventional shared bracket structure, one end of the counter bracket member is fixed to the hoistway wall and the counterweight guide rail is fixed, and the other end of the pair of counter bracket members is connected to the cage. It has been known that it is formed in a substantially U-shape having a main bracket member for fixing a guide rail for use (see Patent Document 1).

And as a positioning fixing method of this shared bracket, after first positioning and fixing the first fixing member used to fix the pair of counter bracket members to the hoistway wall,
The counter bracket member to which the main bracket member is attached is positioned with reference to a counter centering reference line that hangs down from the top of the hoistway, and one end thereof is welded and fixed to the first fixing member.

Then, a second fixing member for gripping and fixing the car guide rail is positioned and welded to the main bracket member using the main centering reference line.

  By the way, according to the common bracket positioning and fixing method of the above prior art, the timing of welding and fixing the first fixing member and the counter bracket member, and the second fixing member and the main bracket member is dispersed. There was a problem of lowering welding work efficiency.

  In addition, the counter bracket member and the second fixing member have to be positioned and fixed following the dimension from the reference line, and there is a problem that the work is complicated.

  The present invention has been made to solve the above-mentioned disadvantages, and an object of the present invention is to provide a method for installing a shared bracket device for an elevator that makes welding work efficient and facilitates positioning work.

In order to achieve the above object, the present invention comprises a pair of counter bracket members, one end of which is fixed to a hoistway wall via a first fixing member and which fixes a counterweight guide rail, and a car guide rail. In an installation method of a shared bracket device for an elevator formed in a substantially U-shape including a second fixing member for fixing and a main bracket member for connecting the other ends of the pair of counter bracket members. The pair of first fixing members are positioned and fixed to the hoistway wall, and the counter bracket member to which the main bracket member is attached is positioned with reference to a counter centering reference line hanging from the hoistway top. Then, after temporarily fixing one end of the counter to the first fixing member using a temporary fixing member, the counter centering reference line and the first fixing member are temporarily fixed. The second fixing member is positioned by using the fixing guide device indicating the fixing position of the second fixing member by matching with the reference portion, and temporarily fixed to the main bracket member using the temporary fixing member. After
The first fixing member and the counter bracket member, and the second fixing member and the main bracket member are fixed by welding, and finally the temporary fixing member is removed.

  According to the present invention, as described above, after temporarily fixing with the temporary fixing member, the first fixing member and the counter bracket member, and the second fixing member and the main bracket member are continuously fixed by welding. Therefore, the welding work efficiency can be improved.

  Moreover, according to this invention, a 2nd fixing member can be easily positioned using a fixed guide apparatus, without using a reference line.

  According to the elevator bracket mounting method of the present invention, the welding operation can be made efficient and the positioning operation can be facilitated.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  First, the structure of the elevator common bracket positioning apparatus using the installation method of the present invention will be described with reference to FIG. FIG. 5 is a perspective view showing a configuration of a shared bracket device for an elevator installed in the present invention.

  In the figure, a common bracket device for an elevator has a counter bracket member 2 whose one end is fixed to a hoistway wall via a first fixing member 1 and a counterweight member guide rails 5a and 5b, and a car guide. It includes a second fixing member 4 that fixes the rail 6, and has a main bracket member 4 that connects between the other ends of the pair of counter bracket members 2.

  Next, the installation method of the elevator common bracket positioning device according to the present invention will be described with reference to FIGS. 1 to 3 are perspective views showing a method for installing the shared bracket device for an elevator according to the present invention, and FIG. 4 is a plan view showing a method for installing the shared bracket device for an elevator according to the present invention.

  First, as shown in FIG. 1, the pair of first fixing members 1 are positioned and fixed to the hoistway wall with reference to the counter centering reference lines 7a and 7b hanging from the top of the hoistway.

  And after connecting between the other ends of a pair of counter bracket member 2 with the main bracket member 3, this counter bracket member 2 is positioned on the basis of the counter centering reference lines 7a and 7b, and is in a temporarily positioned state. The one end side is temporarily fixed to the first fixing member 1 by using a temporary fixing member 8a such as a giant clam vise.

  In this state, as shown in FIG. 2, the counter bracket member 2 is used by using the inserts 9a and 9b with reference to the counter centering reference lines 7a and 7b hanging from the hoistway top portion indicating the fixing position of the counter bracket member 2. The counter bracket member 2 is hit with a hammer or the like (not shown) so as to be positioned, and is fixed using the temporary fixing member 8a.

  In this state, as shown in FIG. 3, as the positioning of the second fixing member 4, the positioning reference portion 10a of the fixed guide device 10 is aligned with the counter centering reference lines 7a and 7b hanging from the top of the hoistway.

  Further, as shown in FIG. 4, after the fixed guide device 10 is temporarily fixed to the pair of counter bracket members 2 using the temporary fixing member 8b, the fixed guide device 10 is aligned with the second fixing member positioning guide portion 10b of the fixed guide device 10, and The two fixing members 4 are placed on the main bracket member 3 and temporarily fixed using the temporary fixing member 8c.

  Then, after removing the temporary fixing member 8b and the fixing guide device 10, the first fixing member 1 and the counter bracket member 2, and the second fixing member 4 and the main bracket member 3 are fixed by welding, respectively. The installation work of the present invention is completed by removing the temporary fixing members 8a and 8c.

  As described above, according to the present invention, the second fixing member 4 can be easily positioned using the fixed guide device 10 without using the reference line. In addition, since the welding operation can be performed continuously, the work efficiency is improved.
