Description

  The present invention relates to a device for monitoring wind force acting on a portable device used in a cableway during operation.

  The cableway is a well-known facility that operates by pulling a rope between the stops, hanging a carrier on the rope, and pulling the carrier by the rope. A strut is erected in the track of the cableway, and the rope is supported by this strut and is elevated from the ground surface with a certain distance. Therefore, the cable carriage is operated at a considerably higher height than the ground surface.

  As described above, since the cable carrier is suspended from the rope, it has the characteristic that the winder blows the carrier, and the carrier is operated at a position considerably higher than the ground surface. Because of this, careful attention must be paid to the operation during strong winds. In particular, if wind is blown to the transporter from the side with respect to the direction of travel of the transporter, the transporter will roll, and if there is a large roll on the transporter, the transporter and the support may come into contact with each other. It is.

For this reason, conventionally, wind speed is monitored by installing an anemometer on a pole or stop at a location where wind resistance is strong on the cableway, and depending on the strength of the wind speed, decelerating and stopping operations can be performed manually or automatically. (Patent Document 1).
Registered Utility Model No. 3024830

  In such a conventional method, the wind speed at a specific point is observed and used, and the operation is determined based on the wind state at the specific point. However, cable tracks are often formed on complex terrain such as mountainous areas, and the wind direction and wind speed generated at each point along the cable track are not uniform depending on the location. Since there are also changes over time, there are cases where the wind condition in the track cannot be grasped well at a small number of observation points.

  In order to solve such problems, it is necessary to monitor the wind speed by increasing the number of observation points, such as attaching an anemometer to all the struts in the track, or separately installing an anemometer strut. Although it is conceivable, there is a problem that such a facility is not economical because the cost is excessive.

In response to this problem, the present invention provides a wind direction / anemometer that is attached to a cableway carrier and measures the wind direction and wind speed and outputs data, a control device that controls the operation of the cableway at a stop, and the wind direction / anemometer. And a communication means for transmitting the data to the control device, and a wind monitoring device for a cableway carrying device, wherein a wind direction / anemometer frame framed by a pipe member is provided at a lower portion of the carrying device, and the wind direction The upper side of the anemometer frame is provided so that the anemometer / anemometer is located below the transporter, and the control device determines the cableway from the wind direction / anemometer data and the traveling speed of the transporter. The actual wind direction and wind speed at the position of the carrier on the track are calculated, and the calculated actual wind direction and wind speed are compared with the threshold values set corresponding to the actual wind direction and wind speed at the position of the carrier. do it It is characterized by controlling the road operating conditions.

  The cable monitoring device wind monitoring device of the present invention is equipped with a wind direction / anemometer attached to the carrier, and this wind direction / anemometer data is input to the cableway control device to control the operation of the cableway. Since the wind direction and the wind speed acting on the transporter are measured and controlled, it is possible to accurately detect the danger of operation and to improve the safety in operation.

Hereinafter, an embodiment of the present invention in a crossing ordinary cableway that operates using a relatively large carrier among various cableway will be described with reference to the drawings. FIG. 3 is a side view showing a line of a crossing ordinary cableway. In the figure, a support line 3 is stretched between the foot-side stop 1 and the summit-side stop 2, and a support column 4 is erected to support the drooping of the support line 3 at an almost intermediate position. ing. Furthermore, EI ropes 5 in parallel with支索3 are stretched to circulate between the two stationary field 1 by one of the drive device with the stop field 1 and 2 this Ei ropes 5 Driven and circulates in the track.

  The carrying device 6 includes a traveling machine 7 that travels along the support 3 with traveling wheels, and a passenger car 8 that is suspended on the traveling machine 7 so as to be swingable in the front-rear direction and the left-right direction. The cable is suspended in the vertical direction regardless of the inclination of the cable track or the traveling machine 7. The cable 5 is connected to the traveling machine 7, and as the cable 5 is driven and moved, the transporter 6 moves in the track, and thus the cableway is operated.

1 and 2 are a side view and a front view of the transporter 6. In the figure, a suspension member 10 is formed at the lower part of the passenger car 8 of the transporter 6 so as to protrude downward at four symmetrical positions on the front and rear and on the left and right with respect to the center of the passenger car 8. The wind direction / anemometer frame 11 framed by the pipe members (curved pipe member 12, connecting pipe member 13) is fixed.

That is, the wind direction / anemometer frame 11 is provided with a curved pipe member 12 having a shape curved in a bow shape downwardly between the front and rear suspension members 10 with respect to the traveling direction of the transporter 6. The central portion between the curved pipe members 12 is connected by a single connecting pipe member 13. An air direction / anemometer 14 is attached to the central portion of the connecting pipe member 13.

  Various types of anemometers / anemometers can be used as the anemometer / anemometer 14, but in the figure, since they are small and highly accurate, they are shown using an ultrasonic anemometer / anemometer 14. Yes. The wind direction / anemometer 14 measures the wind speed from the traveling direction and the lateral direction of the transporter 6 at predetermined time intervals, and outputs the measurement data as a digital signal or an analog signal.

The wind direction / wind speed signal output in this way is transmitted to a transmission device 15 which is mounted in the carrier 6 and constitutes a communication means. Further, the transmission device 15 stops at either the foot of the mountain or the summit. 1 and 2 , it is transmitted and inputted to a control device (not shown) for controlling the operation of the cableway. Here, the transmission device 15 is conventionally known, and for example, disclosed in Japanese Patent Laid-Open No. 2001-10486 is a wireless means between a carrier and a stop, or disclosed in Japanese Patent Laid-Open No. 6-37680. The means by the induction | guidance | derivation radio | wireless which used the rope | wire as a guide wire loop etc. are used.

  The control device receives various information related to the operation, controls deceleration, acceleration, stop, etc. of the transporter 6 and transmits signals such as the position and speed of the transporter 6 to the operation panel. It has a function to display operation information. As described above, the wind speed data of the traveling direction and the lateral direction of the transporter 6 are transmitted to the control device and input, and further, the input wind speed data and the traveling speed of the transporter 6 are calculated and synthesized. Thus, the actual wind direction and wind speed acting on the transporter 6 are calculated.

In response to the respective wind speeds in the front-rear direction, the lateral direction, and the actual direction, the control device includes thresholds such as “alarm”, “deceleration”, “stop”, etc. Value is set. The control device, by comparing the wind speed data sequence received with a threshold value, performs "issuing an alarm", "the deceleration operation carriage", the control of the operating conditions such as "stop operation" I am doing so. In addition, the wind direction and wind speed data of the control device is output and displayed on the operation panel monitored by the clerk in the stop, and is monitored by the clerk regardless of the automatic operation by the control device. I am doing so.

Generally, the cableway is most affected by the wind direction in the horizontal direction among the three types of wind directions described above (front and rear wind direction, horizontal wind direction, and actual wind direction). Some facilities are adversely affected by the wind force of a specific wind direction at a specific point. Even in such facilities, according to the present invention, the wind direction and the wind speed at the actual position of the transporter 6 are measured and calculated. Therefore, it is possible to monitor well even when the wind in a specific direction at a specific point as described above is warned.
