それより僅かに大きくなるように寸法設定されている。As shown in FIGS. 1 to 3, in this roller exchanging tool, a first wall portion 1a having a screw hole and a second wall portion 1b facing the wall portion 1a are erected substantially parallel to each other. A U-shaped frame 1 having a U-shape and having a high rigidity, and a tip end portion of the U-shaped frame body 1 screwed into the screw hole of the first wall portion 1a of the U-shaped frame body 1 is attached to the second wall portion 1b. On the other hand, a screw member 2 that can advance and retreat, an annular blade member 3 that has an annular blade 3a and is attached to the tip end of the screw member 2, and an opening end is exposed at the tip end of the screw member 2 in the axial direction. It is mainly configured by a guide pin 4 housed and held in a pin mounting hole 2b that extends to the front, and an operating lever 2a is attached to the head of the screw member 2. In addition,
The annular blade member 3 is for cutting the inner peripheral portion of the existing urethane rubber tire 5 along the axial direction, and the inner diameter of the annular blade 3a is the maximum outer diameter of the metal shaft 6 on which the urethane rubber tire 5 is fitted. The ring-shaped blade member 3 can be detached from the tip portion of the screw member 2 because the ring-shaped blade member 3 is dimensioned to be slightly larger than the above. Further, a tapered portion 4a which is widened toward the end is formed at one end of the guide pin 4, and the maximum outer diameter of the tapered portion 4a is equal to or slightly larger than the maximum outer diameter of the metal shaft 6. It is set.

業が完了する。First, the existing urethane rubber tire 5 and the plate-shaped switch lever 8 fitted on the metal shaft 6 are positioned between the blade 3a of the annular blade member 3 and the second wall portion 1b. After setting the roller replacement tool, this annular blade member 3
Is operated toward the second wall 1b, the operation lever 2a is operated to screw the screw member 2 forward. Then, the ring-shaped blade 3a pushed into the screw member 2 is attached to the metal shaft 6
Go around the existing urethane rubber tire 5 around
Since the inner peripheral portion of the urethane rubber tire 5 is cut annularly along the axial direction, the screw member 2 is screwed by a predetermined amount, and then the thick wall portion on the outer side of the cut existing urethane rubber tire 5 is cut by a cutter or the like. By making a cut, the thick portion can be easily removed from the metal shaft 6. After that, the thin portion of the existing urethane rubber tire 5 remaining around the metal shaft 6 is picked up with pliers or the like, stretched, and then cut off with a cutter or the like, whereby the removal work of the existing urethane rubber tire 5 is completed.

しかも安全に行うことができる。That is, when the above-described roller exchanging tool is used, the operation lever 2a of the screw member 2 is operated in a space relatively easy to work in front of the narrow space in which the urethane rubber tire 5 of the door lock switch 7 is installed. By rotating the urethane rubber tire 5, the inner peripheral portion of the urethane rubber tire 5 can be cut into an annular shape. Therefore, the existing urethane rubber tire 5 can be easily removed from the metal shaft 6 only by auxiliary use of a cutter or the like. Efficiently in a short time,
Moreover, it can be performed safely.

Then, with the end surface of the guide pin 4 on the taper portion 4a side in contact with the metal shaft 6, the operation lever 2a is operated to screw the screw member 2 toward the second wall portion 1b. Pin 4 gradually becomes pin mounting hole 2b
The new urethane rubber tire 10 is pushed into the screw member 2 and moves toward the metal shaft 6 side via the taper portion 4a of the guide pin 4 although it is sunk into the inside. Therefore, by screwing the screw member 2 by a predetermined amount, the new urethane rubber tire 10 can be easily fitted onto the metal shaft 6.

になり、極めて高い実用的価値が期待できる。As described above, the roller exchanging tool according to the present invention drives the annular blade member linearly by screwing the screw member. Therefore, when the roller exchanging tool is used, Like a urethane rubber tire for a door lock switch roller, an existing roller member made of a non-hard material that is installed in a narrow space can be cut annularly along the circumference of its metal shaft. This has an excellent effect that the removal work of the roller member can be performed efficiently and safely in a short time only by using it auxiliary. If a guide pin having a tapered portion can be inserted into the pin mounting hole formed in the screw member, a new roller member can be easily attached to the metal shaft using this roller replacement tool. The property is further improved. As a result, even if a large number of urethane rubber tires for door lock switch rollers have to be replaced at a site with a large number of elevator floors, this roller replacement tool can be used to ensure that the replacement work can be completed in a short time. Therefore, extremely high practical value can be expected.
