Description

  The present invention relates to an elevator car maintenance apparatus and an elevator apparatus.

  Normally, maintenance equipment is installed at the top of the elevator hoistway, so maintenance workers get on the elevator car and perform maintenance work. For example, Patent Document 1 discloses an elevator car maintenance work jig that can mechanically limit the ascending of a car before a maintenance worker gets on the elevator car.

JP 2012-20800 A

  In the above-mentioned Patent Document 1, the lift of the car is mechanically limited by the maintenance work jig in advance, but if the maintenance worker does not get on the car, it will reach the maintenance device located at the elevator hoistway top. I can't figure it out. Therefore, when it is found that the maintenance device cannot be reached after getting on the car, there is a problem that the inspection work position cannot be adjusted unless the car is once lowered from the car.

  The present invention has been made in consideration of the above points, and intends to propose an elevator car maintenance device and an elevator device capable of adjusting the inspection work position without adjusting the elevator car. .

  In order to solve such a problem, in the present invention, an inspection work floor installed on an elevator car, a work floor driver for raising the inspection work floor, and a guide rail for guiding the rise of the inspection work floor An elevator car maintenance device is provided.

  According to such a configuration, by raising the work floor and approaching the maintenance device located above the elevator car, maintenance work on the car with high workability and safety can be performed without raising the car. Furthermore, by grounding the guide rail that guides the work floor on the car to the ceiling of the hoistway, the ascent of the car can be mechanically restricted to ensure safety.

  According to the present invention, the inspection work position can be adjusted without adjusting the elevator car, and the workability and safety of maintenance work on the car can be improved.

1 is an overall configuration diagram of a car maintenance apparatus according to an embodiment of the present invention. It is a top view of the car maintenance apparatus concerning the embodiment. It is an installation figure of the guide rail for work concerning the embodiment. It is detail drawing of the check work floor concerning the embodiment.

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

  First, an overall configuration of an elevator car maintenance apparatus according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 1, a maintenance device 1 is attached to the top of an elevator hoistway 2. A maintenance worker who performs maintenance work on the elevator gets on the car 3 and then installs the work floor guide rail 4 on the car.

  The on-car maintenance device is installed on the car 3 in advance. When the inspection work is not performed, the inspection work floor 5 of the car maintenance device is installed at the lowest position on the car 3.

  The maintenance worker installs the fall prevention fence 6 after installing the work floor guide rail 4. The inspection work floor 5 of the car maintenance device rises along the work floor guide rail 4 to a position where it reaches the maintenance device 1 and is inspected by a maintenance worker.

  FIG. 2 is a top view of the car maintenance device. A car frame 7 is provided above the car 3, and a work floor guide rail 4 and an inspection work floor 5 are installed on the car frame 7. Further, the fall prevention fence 6 is installed to secure an inspection work space, and is installed outside the work floor guide rail 4.

  FIG. 3 is a view in which the work floor guide rail 4 is installed on the upper portion of the car 3. The work floor guide rail 4 is installed after the maintenance worker gets on the car 3. A guide rail receiver 8 is installed on the car frame 7 in advance.

  The guide rail receiver 8 has a cylindrical shape, and is inserted into one end of the work floor guide rail 4 and fastened with a guide rail fixing bolt 9 to be fixed. A guide rail position detection switch 10 is provided on the guide rail receiver 8. In the state where the work rail 4 is inserted into the guide rail receiver 8, the power supply of the car maintenance device is not turned on.

  FIG. 4 is a structural diagram of the inspection work floor 5 of the car maintenance device. A work driver 11 is provided under the inspection work floor 5. The work driver 11 has a shape like an electric panda graph jack, for example, and can raise the inspection work floor 5 electrically.

  An inspection work floor position detection switch 12 is provided below the inspection work floor 5. The inspection work floor position detection switch 12 is pressed when the inspection work floor 5 is at the lowest position.

  For example, when the inspection work floor 5 is at the lowermost limit position, the work driver 11 is folded, so that the inspection work floor position detection switch 12 is pressed by a part of the work driver 11. It is good. Further, when the inspection work floor 5 is not at the lowermost limit position, that is, when the work driver 11 is driven by the maintenance worker and the inspection work floor 5 is raised, the inspection work floor position detection switch 12 is not pressed. It becomes a state.

  When the inspection floor position detection switch 12 is not depressed, the maintenance worker can safely perform maintenance inspection work by controlling the elevator car 3 not to move up and down.
