Description

  The present invention relates to a clutch-type brake disassembly jig device, and more particularly to a clutch-type brake disassembly jig device used in an elevator hoist.

  The elevator hoisting machine is equipped with a brake device. For example, in Japanese Patent Application Laid-Open No. 11-199150 (Patent Document 1), when an electromagnetic brake is used for the hoisting machine, the maintenance and inspection of the electromagnetic brake is performed. A method for disassembling an electromagnetic brake is disclosed. The technology disclosed herein provides a work table as a scaffold on a motor of a hoisting machine, and sequentially disassembles disassembled parts of an electromagnetic brake on the work table for inspection and maintenance.

JP-A-11-199150 (paragraph 0009, FIG. 2)

  According to the technique disclosed in Patent Document 1, there is no need to bother to take down the disassembled parts of the electromagnetic brake, which is a heavy object, to the floor of the machine room, and to perform inspection and maintenance of the electromagnetic brake safely and efficiently. It is supposed to be possible. However, inspections and maintenance are carried out by rotating the disassembled parts on the work table or changing the position or orientation. For this reason, if the disassembled parts are heavy, the inspection and maintenance takes time. In addition, the inspection / maintenance has a serious problem in the inspection / maintenance due to the adverse working environment of the hoistway.

  Further, when a clutch brake is used in the hoisting machine, the structure of the clutch brake is completely different from the structure of the electromagnetic brake, and the technique disclosed in Patent Document 1 is applied to the inspection and maintenance of the clutch brake. There is a problem that is almost impossible and leads to danger.

  The present invention has been made paying attention to the above-described problems, and provides a clutch-type brake disassembling jig device that enables safe and short-term inspection and maintenance of the clutch-type brake.

  A disassembling jig device for a clutch brake according to the present invention includes a cart formed of a rectangular plate member having a predetermined thickness, a caster attached to a lower surface portion, and a plate case juxtaposed on the upper surface of the cart. And a plurality of groove portions are formed on the upper surface of the carriage, and a lower surface portion of the plate case is detachably fitted in the groove portions, and a semicircular shape is formed inside the plate case. A hollow portion is formed, and a plurality of rollers with rotating shafts are provided at the bottom of the hollow portion.

  According to the present invention, a plurality of groove portions are formed on the upper surface of the carriage, and the lower surface portion of the plate case is detachably fitted into the groove portions, and the semicircular hollow portion is formed inside the plate case. Since a plurality of rollers with rotating shafts are provided at the bottom of the hollow portion, inspection and maintenance of disassembled parts of the clutch brake can be performed safely and in a short time.

  Preferred embodiments of a clutch-type brake disassembly jig device according to the present invention will be described below with reference to the accompanying drawings. Note that the present invention is not limited to this embodiment, and includes various design changes.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing a clutch-type brake disassembly jig device according to Embodiment 1 of the present invention. In FIG. 1, a clutch-type brake disassembly jig device (hereinafter simply referred to as a brake disassembly jig device) 10 includes a carriage 11 formed of a rectangular plate member having a predetermined thickness, and an upper surface of the carriage 11. A plurality of plate cases 12 are arranged side by side. In addition, casters 13 for moving the carriage 11 are attached to the bottom four corners of the carriage 11.

  As shown in FIG. 2, a plurality of grooves 14 are formed on the upper surface of the carriage 11, and the lower surface portion of the plate case 12 is detachably fitted into the grooves 14.

  As shown in FIG. 3, the plate case 12 is configured such that two semicircular plates 12a are arranged to face each other with a predetermined interval, and the arc portion is covered with a bottom plate 12b. In other words, the plate case 12 is formed like a ship-bottom vessel having a semicircular hollow portion therein. The plate case 12 may be formed by joining members of a semicircular plate 12a and a bottom plate 12b having a predetermined strength by welding or the like, or may be formed by drawing a plate member. .

  Further, the plate case 12 is provided with a plurality of rollers 15 with rotating shafts at the bottom of the semicircular hollow portion as shown in FIG. FIG. 5 shows an enlarged perspective view of the roller 15 with a rotating shaft.

  The plate case 12 is not limited to the shape in which the two semicircular plates 12a are arranged opposite to each other with a predetermined interval and the arc portion is covered with the bottom plate 12b. The shape plates may be arranged so as to face each other with a predetermined interval, and the side surface and the bottom surface thereof may be covered with a rectangular plate, and the hollow portion formed therein may be a semicircular hollow portion. .

  The brake disassembly jig apparatus according to the first embodiment is configured as described above. Next, a procedure for inspection and maintenance of the brake disassembly parts will be described. 6 to 8 are perspective views for explaining the inspection and maintenance procedure of the brake disassembled parts. When inspecting and servicing brake disassembly parts, first, the brake disassembly jig device 10 is set on the hoist 16 as shown in FIG. Next, as shown in FIG. 7, the plate 17 is disassembled from the hoisting machine 16 and set on the brake disassembling jig device 10. At this time, the lower portion of the plate 17 is set so as to be accommodated in the semicircular hollow portion of the plate case 12. FIG. 8 is a perspective view showing this state. 9 to 13 illustrate the above flow.

  After the plate 17 is set in the brake disassembly jig device 10 as described above, the polishing liquid stored in the spray can 18 is sprayed on the surface of the plate 17 as shown in FIG. Inspect and maintain the surface of the plate 17. When the surface of the plate 17 is inspected and maintained, a plurality of rollers 15 with rotating shafts are provided at the bottom of the semicircular hollow portion of the plate case 12, so that as shown in FIG. It can be done by rotating the plate case 12 by hand and changing the part to be inspected and maintained. After the inspection and maintenance, the carriage 11 is again adjacent to the hoisting machine 16, and the plate 17 that has been inspected and maintained is attached. In addition, since the plate case 12 can be removed from the cart 11, the wear powder after inspection and maintenance accumulated in the plate case 12 can be easily discarded.

  As described above, according to the brake disassembly jig device according to the first embodiment, the plate case 12 is fitted into the groove portion 14 formed in the carriage 11, and the carriage 11 is placed near the brake assembly when the brake is disassembled. Each time the plate 17 is installed and disassembled, each plate 17 is stored in the plate case 12. After the disassembly, the carriage 11 is moved to perform inspection and maintenance. As a result, it is possible to prevent the generated abrasion powder from being scattered outside the disassembled parts.

  In addition, the inspection and maintenance of the plate 17 can be changed by the roller 15 with the rotating shaft attached to the plate case 12 while the stored plate 17 can be easily rotated by hand. Even heavy objects can be inspected and maintained in a short time.

  Furthermore, the abrasion powder generated by inspection and maintenance accumulates at the bottom of the plate case 12 and can be prevented from scattering to other disassembled parts, and can be discarded after the plate 17 is assembled.
