  The operations (i) and (ii) as described above are often repeated for the number of stops of the elevator, and the workability is reduced. In particular, when the number of stop floors is relatively large, such as a high-speed elevator, the work time is significantly increased. Further, when positioning a part, an operation of drawing a ruled line is generated for the target part, but there may be a case where a ruled line cannot be drawn for the design surface of the target part.

  According to the elevator hall device construction marker of the present invention, the laser beam emission is performed so that the emission control unit indicates the machining position of the hall device to be machined as the laser beam incident position based on the inputted design information. Since the optical axis angle of the laser beam of the means is controlled, the operations (i) and (ii) as in the conventional method are unnecessary, and the processing position can be shown even on the design surface. It is possible to efficiently perform the positioning operation of the processing position of the landing equipment.

In addition, the car-side control device 20 can communicate with the control panel 3 via the control cable 12 that connects the upper part of the hoistway 1 and the car 5.

  The pair of laser beam generators 21A and 21B and the laser beam generation controller 23 are detachably attached to the upper surface of the upper beam of the car frame 8. Further, the pair of laser beam generators 21A and 21B are arranged at intervals in a direction (left and right direction in FIG. 2) in which the pair of car guide rails 10A and 10B face each other. Here, the car frame 8 is arranged so as to connect the pair of car guide rails 10A and 10B in the horizontal direction, that is, to coincide with the rail core (reference line X) of the car guide rails 10A and 10B in the horizontal direction. ing. The pair of laser beam generators 21A and 21B are also arranged so as to coincide with the rail cores of the car guide rails 10A and 10B in the horizontal direction.

  Laser beam generators 21A and 21B emit laser beams α and β, respectively. The laser beam generators 21A and 21B can change the optical axis angle (irradiation angle) of the laser beams α and β in the horizontal direction and the vertical direction (having an optical axis angle adjustment mechanism). The laser beam generation control device 23 controls the emission start / exit stop and the optical axis angle of the laser beams α and β of the laser beam generation devices 21A and 21B. The laser beam generation control device 23 is connected to the car-side control device 20 and can communicate with the car-side control device 20.

  In the laser beam generation control device 23, design information converted in advance into 3D (three-dimensional) data is inputted and registered. This design information is information indicating the layout of each device in the hoistway 1 and is information including the processing position of the landing device 30 and the like. In the laser beam generation control device 23, position information of the laser beam generation devices 21A and 21B with the car 5 as a reference is input and registered in advance.

  Further, the laser beam generation control device 23 receives car position information from the control panel 3 via the car-side control device 20 and the control cable 12. The laser beam generation controller 23 calculates the positions of the laser beam generators 21A and 21B in the hoistway 1 based on the position information of the laser beam generators 21A and 21B in the car 5 and the car position information. .

  Further, the laser beam generation control device 23 calculates the incident positions of the laser beams α and β on the landing device 30 side from the positions of the laser beam generation devices 21A and 21B in the hoistway 1. Based on the design information, the laser beam generation control device 23 then adjusts the laser beam generation devices 21A, 21A, 21B so that the calculated incident positions (display positions) of the laser beams α, β on the hall device 30 side coincide with the processing positions. The optical axis angles of the laser beams α and β of 21B are controlled, and the laser beams α and β are emitted from the laser beam generators 21A and 21B.

  Here, when there are a plurality of machining positions on the same landing floor, the control contents of the optical axis angles of the laser beams α and β by the laser beam generation control device 23 for each of the plurality of machining positions are formed into a program pattern. By forming the program pattern in this way, a plurality of machining positions can be sequentially switched and shown in a machining order registered in advance. Further, at each landing floor, the laser beam generation control device 23 can sequentially switch and indicate a plurality of processing positions with the same operation pattern.

The optical axis angle can also be controlled. Further, the laser beam generation control device 23 receives an end operation indicating that one work process has been completed from a work terminal, a computer, or the like, and sequentially shows a plurality of processing positions corresponding to the work procedure. The optical axis angles of the laser beams α and β of the beam generators 21A and 21B are controlled.

  Further, the laser beam generation control device 23 outputs information on the processing position of the landing equipment 30 to be processed to a work terminal / computer, or a notification means (not shown) such as a speaker in the car room 9, Through this notification means, the processing order and processing contents are guided (instructed) to the worker by at least one of characters, video and audio. This also functions as a work procedure guide for workers.

  Next, positioning work using the laser beams α and β will be described. FIG. 3 is a flowchart showing a positioning operation using the laser beams α and β. In FIG. 3, for simplicity, the laser beam generation control device 23 is described as an emission control unit.
