Description

  The present invention relates to an operating device that designates a support column installed upright in a ropeway track during operation of the ropeway, and automatically reduces the speed of the transporter when the transporter passes through the specified support column. .

  The ropeway 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 on the ropeway track, and the rope is supported by this strut and is elevated from the ground surface with a certain distance. Therefore, the ropeway transporter is operated at a considerably higher height than the ground surface.

  As mentioned above, since the ropeway carrier is suspended from the rope, it has the characteristic that the winder blows and causes the carrier to swing, 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, it is detected that the carrier has swung to a set angle by attaching a deflection angle detector to the carrier, and this is transmitted to the cab by ultra high frequency (UHF), and a speed control circuit for the cab is obtained. And a method of transmitting a command for deceleration or stop by a main circuit has been proposed (Patent Document 1). In addition, in the ropeway, it is generally performed that a driving staff monitors the operation state on the track, and performs a deceleration operation when the transporter passes through the support column, so that the prop position is passed at a low speed. ing.

  However, with regard to the deceleration operation by the driver, there is a difference in the skill and proficiency of the driver, so the speed of the transporter may not be in time, or conversely, the operation time may be extended because the vehicle is decelerated at an early position. there were.

  The present invention has been made in view of such circumstances, and provides an apparatus capable of accurately controlling the speed of a transporter during a strong wind of a ropeway and performing a safe operation when passing through a support column. With the goal.

Corresponding to this problem, the present invention provides a carrier that moves between stops, a rope that is connected and pulled by the carrier, a support that supports the rope, a prime mover that drives the rope, A control device for controlling the prime mover; and a transporter position detector for detecting a position of the transporter and transmitting a signal to the control device, wherein the control device stores an operation speed pattern between the stops, and the operation A driving device that automatically operates based on a speed pattern and a signal of the transporter position detector, wherein the control device receives the support column identification information for selecting a specific support column when the specific support column is input. A new driving speed pattern is generated by further setting the corresponding deceleration completion position, acceleration start position, deceleration start position, and acceleration completion position in the driving speed pattern, and the automatic operation of the carrier is performed based on the new driving speed pattern. luck It is characterized in that the automatic deceleration operation at the selected post located at is performed.

The ropeway automatic deceleration operation device of the present invention generates a new operation speed pattern in which the carrier decelerates and operates the specified strut position from the operation speed pattern stored in the control device when the strut is specified. Since the automatic operation of the transporter is performed along the new operation speed pattern, the vehicle can be safely operated because the vehicle is surely decelerated at an appropriate position. In addition, since deceleration and acceleration are always performed at a fixed position, the operation time is stabilized, and operation management becomes easy.

  Hereinafter, embodiments of the present invention in a ropeway will be described with reference to the drawings. FIG. 3 is a block diagram showing the entire ropeway. A branch 12 is stretched between the foothill stop 10 and the summit stop 11. The end of the abutment 12 on the summit stop 11 side is fixed to a concrete foundation or the like, while the abutment weight 14 is suspended from the end of the summit stop 10 side to keep the tension of the abutment 12 constant. I keep it. A carrier 16 is suspended and supported on the support 12 and moves along the support 12.

  The cable 13 is endlessly circulated and stretched between the foothill stop 10 and the summit stop 11, and is wound around the driving pulley 17 and driven at the summit stop 11. A transporter 16 is fixed to the cable 13, and the transporter 16 is operated along with the movement of the cable 13. In addition, an eaves weight 15 is suspended from the eaves 13 at the foothill stop 10, and the operation of the transporter 16 is stably performed when a certain tension is applied to the ebb 13. . These support lines 12 and the extension lines 13 are supported by a support column 23 erected in the ropeway line.

  A prime mover 19 is mechanically connected to the prime mover pulley 17 via a speed reducer 18, and a controller 22 is electrically connected to the prime mover 19 to control the rotation of the prime mover 19. The control device 22 receives a signal from a transporter position detector 21 that detects a position of the transporter 16 by transmitting a signal by the rotation of the guide pulley 24, and transmits a signal by the rotation of the prime mover 19. A signal from the speed detector 20 for detecting the speed of the vehicle is input, and the operation speed is controlled based on these signals.

  The operation speed pattern as shown in FIG. 2 is set and stored in the control device 22, and the speed corresponding to the transporter moving position detected by the transporter position detector 21 is derived based on the operation speed pattern. Then, the rotational speed of the prime mover 19 is controlled to perform automatic operation. In this driving speed pattern, the vertical axis represents the speed and the horizontal axis represents the distance. First, the transporter 16 departs the stop 53 at the very low speed 51 in response to the driving start signal, and then reaches a constant acceleration. To be accelerated. When the transporter 16 reaches the acceleration end position 54 and the speed reaches the constant speed 52, the subsequent operation is performed so as to maintain the constant speed 52. Thereafter, when it is detected from the signal of the transporter position detector 21 that the transporter 16 has reached the deceleration start position 55, the transporter 16 decelerates at a constant deceleration rate, and after sufficiently decelerating, enters the stop 56 at the very low speed 51. Enter and stop. Normal operation is performed as described above.

  Next, the ropeway track is generally long and is often operated in mountainous areas, so that during transport in strong winds, the roll of the carrier 16 is caused at a specific position in the track. In order to avoid danger, there is a case where it is desired to perform the decelerating operation of the transporter 16 with a specific support 23. Further, in this case, since the swing of the transporter 16 is affected by the number of passengers, there is little swing when it is almost full, and it may not be necessary to decelerate at the column position. .

  In such a case, automatic deceleration operation is performed as follows. First, to the control device 22, the column number for performing the deceleration operation is input, and the distance between the position at which the carrier 16 completes the deceleration with respect to the column 23 and the position where the vehicle 16 accelerates again after passing through the column 23, or A predetermined distance is set. Furthermore, it is specified and input whether the carrying device 16 to which this deceleration operation is applied is an up-loading device, a down-loading device, or an up-down and down-loading device. The control device 22 stores position data of the support 23 in advance, and the transporter 16 decelerates when the specified transporter 16 passes the specified support 23 based on the position data and the input data. The driving speed pattern is calculated and set so that the vehicle passes through the vehicle and travels along this.

  FIG. 1 shows an example in which an operation speed pattern is specifically set. The lower diagram in FIG. 1 represents the operation speed pattern set as described above, and the upper diagram schematically represents the ropeway line corresponding to the operation speed pattern. In the figure, the ascending transporter 16a travels from the foothill stop 30 in the direction of arrow A, and passes through the No. 1 strut position 32 while being decelerated at the No. 2 strut position 33. Shows the settings.

  The No. 1 support column position 32 and the No. 2 support column position 33 are stored in advance in the control device 22 as position data. Here, by selecting and inputting the No. 1 support column, the position data of the No. 1 support column position 32 is designated. The A distance X1 and a distance X2 traveling at a slow speed 38 are input to both front and rear sides of the No. 1 post position 32, or a predetermined distance is designated, and this distance is the position of the No. 1 post position 32. The acceleration start position 36 and the deceleration completion position 35 are determined by adding and subtracting to the data. The slow speed 38 is a preset speed, and is 1 m / s, for example. Subsequently, the control device 22 calculates the distance required for deceleration and acceleration from the difference between the slow speed 38 and the constant speed 52 (for example, 5 m / s) and the determined deceleration or acceleration, and the deceleration start position 34 and An acceleration completion position 37 is determined.

  Each of the above positions is set in addition to the normal operation speed pattern described above, and the automatic operation of the transporter 16a is performed along the newly generated operation speed pattern. That is, in response to the operation start signal, the transporter 16a starts operation at the slow speed 51 from the foothill stop 10 and is accelerated to a constant speed 52 after traveling a certain distance, and thereafter moves at a constant speed 52. In the control device 22, when it is detected by the signal from the transporter position detector 21 that the transporter 16 a has reached the deceleration start position 34, the transporter 16 a is decelerated by a constant deceleration until the deceleration completion position 35. Control is performed. Next, after reaching the deceleration completion position 35, the first column position 32 is safely passed at a constant slow speed 38. Thereafter, the acceleration start position 36 is detected, acceleration is started, and the constant speed 52 is restored again at the acceleration completion position 37. After that, it is the same as the normal driving speed pattern. When the transporter 16a reaches the deceleration start position 55 provided in front of the stop, deceleration starts, and then enters the stop 56 at the slow speed 51 and stops. To do.

  As described above, the case where the ascending transporter 16a performs the deceleration operation at the No. 1 strut position 32 has been described. However, it is possible to designate a plurality of struts as the designated struts. A carrier can be specified. In this case, as described above, the deceleration start position, the deceleration completion position, the acceleration start position, and the acceleration completion position are calculated and set for each carrier corresponding to the designated strut position, and each position is reflected in the driving speed pattern. What should I do?
