  As shown in FIGS. 1 to 3, the elevator speed governor testing apparatus according to the present invention has a rotating roller 3 a that is brought into contact with a sheave 1 b of the elevator speed governor 1, and the rope is connected via the rotating roller 3 a. A speed detector 3 that detects the rotational speed of the vehicle 1 b and a speed detector holder 4 that holds the speed detector 3 on the frame 1 a of the governor 1 are configured.

  The speed detector holder 4 is attached to the speed detector holder frame 4a as an attachment portion to the frame 1a, and the relative position of the speed detector holder 4 is variable with respect to the speed detector holder frame 4a. A speed detector holding base 7 for holding the speed detector 3 is provided so that the rotating roller 3a is brought into contact with the sheave 1b.

  Then, the speed detector holder frame 4a is slid from above the side edges 11a of the frame 1a so as to engage with the side edges 11a of the frame 1a, and the elevator governor. A stopper portion 6 that makes contact with the upper edge portion 12a of one frame 1a and performs vertical positioning, a screw hole 9a, and screwed into the screw hole 9a and screwed into contact with the frame 1a to fix the tension. It has a thumbscrew 9 to perform.

  The pair of bent portions 5 and the stopper portion 6 may be integrated with the speed detector fixing jig frame 4a or may be divided parts. Of course, if a plurality of the thumbscrews 9 and the screw holes 9a are provided, the test apparatus can be more firmly attached.

  Further, the speed detector holding base 7 is rotatably connected to the speed detector fixing holder frame 4a by a speed detector holding base attaching thumbscrew 10 and the rotating roller 3a is connected to the sheave 1b at an appropriate position. Can be brought into contact.

  As shown in FIG. 5, the speed detector holding base 7 is provided with at least one hook fastener 8 in the present embodiment for fixing the speed detector 3. Yes. These hook-and-loop fasteners 8 are permanently installed on the speed detector holding base 7 by bonding, screw fixing, and the like, thereby preventing the hook-and-loop fastener 8 from dropping when the speed detector 3 is fixed, The workability is prevented from deteriorating.

  Next, a method for attaching the elevator governor test device will be described.

  In order to attach the test device to the elevator governor 1, first, the bent portion 5 of the speed detector holder frame 4a is guided downward from the upper side of the frame 1a to the side edge portion 11a, and the bent portion 5 is displaced downward.
