Next, the operation of the elevator dimension measuring apparatus having the above configuration will be described with reference to FIGS. FIG.
And as shown in FIG. 2, the said apparatus is installed on the elevator car 2. FIG. Next, as shown in FIG. 3, setting is performed so that the calculation unit 13D of the computer 13 recognizes the detailed measurement unit. For this purpose, the motor 14 is finely operated while a technician visually checks the position indicated by the laser pointer 15 by the fine movement operation unit 13A. Then, when it reaches the detailed measurement position 30, the fine movement operation is stopped. The fine movement operation is an operation in which the motor 14 is rotated at a very low speed, unlike normal measurement.

When the motor 14 is stopped at the detailed measurement position 30, the rotation angle of the motor 14 at that time is stored in the angle storage unit 13B, and the detailed measurement position is positioned in advance. In addition,

Any of those received and stored from outside may be used.

After these initial procedures, the computer 13
Based on this control program, the dimensions in the hoistway are automatically measured. This is based on the following procedure.

The height position of the car 2 in the vertical direction is obtained as a distance from the range finder to the hoistway ceiling surface 20 by a car position measuring laser range finder 12, and the measured data is stored in a storage unit 13E of the computer 13. To memorize. The horizontal distance measurement at each height position of the hoistway 1
Laser distance meter 11 for horizontal distance measurement while rotating
Is performed by scanning the periphery 360 ° horizontally. The distance from the laser distance meter 11 for measuring the horizontal distance to each unit is obtained as measurement data in comparison with the rotation angle, and is stored in the storage unit 13E of the computer 13. At the time of these measurements, at the detailed measurement position 15 recognized in advance, the measurement is performed by reducing the rotation angle of the motor 14 or combining the operation of changing the rotation direction of the motor 14.

The arithmetic unit 13D of the computer 13 executes an arithmetic operation based on the data stored in the storage unit 13E, and measures the distance between the walls based on the measurement data of the horizontal distance of each part in the hoistway 1 at each position of the elevator car 2. And rail gauge dimensions, and drawing data of the inner shape of the hoistway 1 are calculated.

The above operation is program-controlled by the computer 13. This operation will be described in more detail with reference to the flowchart shown in FIG. The motor 14 receives an origin return command from the computer 13. With this command, the motor 13 returns to the origin 1 and waits (step S05).

Next, the computer 13 acquires the rotation angle data of the motor 14 (step S10). At this time,
The computer 13 recognizes that the home position return has been completed.

Next, a laser distance meter 1 for measuring the car position
2 receives the distance measurement start command from the computer 13 and measures the distance in the vertical direction. Thereby, the computer 13 acquires the distance data in the vertical direction, converts it into the car position data by the internal operation unit 13D, and stores it in the storage unit 13E (steps S15, S20).

Next, the motor 14 receives the rotation / stop command from the computer 13, rotates by the normal rotation angle set in advance in the control program, and stands by (step S25). Thereafter, the motor 14 receives the rotation angle data acquisition command from the computer 13 and transmits the rotation angle data to the computer 13 (Step S30).

Next, the acquired rotation angle data is compared with the detailed measurement position data, and when the data reaches the detailed measurement position, the rotation angle is switched to a fine rotation angle for detailed measurement (steps S35 and S40). Otherwise, the normal rotation angle is maintained (NO in step S35).

The detailed measurement position data can have a certain range. For example, if the range is within ± 10 ° from the recognized position, this ± 10 °
When it reaches the range of °, it switches to the fine rotation angle for detailed measurement set in advance in the control program. In addition, when the value falls outside this range, the rotation angle is returned to the normal rotation angle. Furthermore, a process of returning by a certain angle when stopping beyond the detailed measurement position may be incorporated.

Next, a laser distance meter 1 for measuring a horizontal distance.
1 receives a distance measurement start command from the computer 13,
Start distance measurement. Then, the computer 13 acquires the horizontal distance measurement data and stores it in the storage unit 13E (steps S45 and S50).

Thereafter, the processes of steps S25 to S50 are repeated until the motor 14 measures a predetermined measurement range, that is, a horizontal distance of 360 °.

When the horizontal dimension measurement is completed at the car position, the car 2 is moved to the next measuring height position, thereby moving the height of the elevator size measuring device in the vertical direction. Then, at the predetermined height position, the car position is measured and the horizontal distance of each part in the hoistway 1 is measured by the processing of steps S05 to S50 as described above.

When the computer 13 completes the automatic measurement of the horizontal distance data at each height position in the hoistway 1 in this way, it calculates the distance between the walls of the hoistway 1 and the dimensions of the rail gauges. Data conversion processing is also performed, and the obtained drawing data is
3 to automatically create and output the drawing by processing it with the CAD program incorporated therein, or take it off-line from the computer 13 and process it by another computer using the same CAD program as above to automatically generate the drawing. Can be created.

Thus, in the elevator dimension measuring apparatus of this embodiment, the apparatus is installed on the elevator car, and the car is moved to automatically measure the dimensions in the hoistway at each car position. This eliminates the need for multiple personnel to work on the car for dimensional measurement work, and reduces individual differences and errors as in the case of actual measurement by human systems. , Accurate dimension measurement is possible. In addition, the horizontal distance to each part in the hoistway is measured by small angles in parts with complicated shapes, and the distance is measured by coarse angles in parts with simple shapes. The measurement time can be shortened, and necessary details can be measured more accurately than when measuring at coarse angles.
