Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a regular interval operation method and apparatus for continuously maintaining the departure interval of carriages of an automatic circulation cableway at regular intervals.

A self-propelled circulation cableway connects pulleys installed at terminals (stops) at both ends, wraps an endless cable, and circulates the cable. Let me hold the rope,
This is a transportation facility that moves the carrier along with the cable. In addition, at the terminal, the rope gripping machine roams the rope and is slowly transported by a forwarding device, and passengers are boarded and alighted during this forwarding.

On the other hand, in the case of a fixed circulation cableway, a cable gripping machine equipped with a carrier is semi-permanently fixed to the endless cable at predetermined intervals, and the cable is operated in a circular manner. Since no gripping and radiating is performed at the time, the once set interval is always maintained, and there is no risk of the interval being disturbed.

However, in a fixed circulation cableway, the operating speed on the cableway line and the operating speed inside the terminal are the same, so
There is a limit to the speed at which passengers can get on and off vehicles moving within the terminal without danger, and this eventually becomes an obstacle, making it impossible to increase the operating speed of fixed circulation cableways beyond a certain limit.

However, in an automatic circulation cableway, the rope gripping machine is separated from the cable at the terminal and is sent by a forwarding device at a slow speed suitable for boarding and alighting passengers, so the operating speed on the cableway is
It is possible to freely select a vehicle without being constrained by the speed required for boarding and alighting. This feature of the automatic circulation cableway has attracted attention, and recently it has been used not only for cableways using passenger cars, but also for ski lifts using open chair carriers, where fixed circulation cableways were previously the mainstream. It is expanding and attracting attention.

However, although automatic circulation cableways have these characteristics, as mentioned above, the cables and cable grips are detachable, so unless special equipment is installed and regulated at the time of departure from the terminal, Unable to maintain constant spacing between carriers. If the spacing between the carriers is not regulated at a constant level, the spacing between the carriers may become uneven, and the carriers may be concentrated near specific points on the cable, causing problems with the strength and safety of the cable, or causing an imbalance in both the reciprocating lines of the cableway. This may occur and impair driving conditions. When the spacing between carriers becomes sparse, there will be a surplus in the planned number of carriers, which will accumulate in the terminal and impede operations, increase passenger waiting time, and cause losses due to a reduction in transportation capacity. Therefore, regular interval operation is an important prerequisite for automatic circulation cableways.

As a method or device for operating a carrier at regular intervals, for example,
609 ``Minimum departure interval automatic regulation device in a rope gripping machine for a single-track automatic circulation type passenger cableway'' JP 54-17242 ``Minimum departure interval automatic regulation device in a rope gripping machine for an automatic circulation type passenger cableway'' JP 56-25048 Others have been proposed and implemented, such as the ``Automatic Circulation Cableway Cargo Departure Control System.''

These proposals include regulating the distance between the carrier departing from the terminal and the preceding carrier at each terminal so that the carrier departs from the terminal by a certain distance or after a certain period of time, or in addition, The carriers are arranged in a line ready for departure.

In addition, the conventional method or device separately installs a spacing regulating device at both end terminals, and controls the distance when the carrier departs from one terminal for the outward journey and when it departs from the other terminal for the return journey. Departures were to be conducted with distance regulations in place.

With such a method or device that regulates departure intervals at both terminals, for example, if there is a passenger boarding problem at one terminal and it is desired to temporarily suspend the departure of a carrier, the cableway operation can be stopped at one terminal without completely stopping. It has the advantage that it can be processed by itself. However, on the other hand, if it is not economical to install the device at both terminals, or if the distance or time settings of the regulating devices at both terminals are not accurately matched, the difference in departure intervals between the two terminals will repeatedly accumulate, and one terminal will Transporters were unevenly distributed in the area, and there was a risk that they would be backed up.

Therefore, such conventional methods and devices are often used for cableways used for the transportation of passengers as well as for cableways of a relatively large scale, as well as for cableways used for the transportation of passengers, but are mainly used for one-way cableways for transporting skiers. This method is not economical when used on a cableway used solely for the transportation of passengers or on a relatively small scale cableway, and there has been a desire to develop a method or device that is simple in structure and reliable.

In response to these circumstances, the present invention provides a reliable device with a simple structure that is suitable not only for large-scale cableways but also for cableways used for transporting passengers only on one side and relatively small-scale cableways. The purpose of this study is to propose an economical method and device for operating an automatic circulation cableway at regular intervals.

In response to this purpose, the present invention provides a carrier equipped with a rope gripping machine,
A cable circulating between the pulleys of the terminals at both ends, equipment for moving the carrier, that is, a forwarding device disposed at each terminal of the terminal to route the carrier from the arrival side to the departure side, and each terminal of the terminal. an acceleration device disposed at the terminal and interposed in the departure route of the carrier to accelerate the carrier; and a deceleration device disposed at each terminal and interposed in the arrival route of the carrier to decelerate the carrier. In an automatic circulation type cableway, in which the carrier is transported by moving the carrier along with the circulation of the cable, the carrier is allowed to depart only at one of the terminals at both ends by regulating the carrier at regular intervals. and a device configured such that the operating speed of each device of the carrier operation equipment and the operating speed of the cable are always maintained in a proportional speed, and the control is regulated by the constant interval forwarding device. The carrier is characterized in that the constant interval relationship between the carriers that departed is maintained during one cycle of the carriers, and the carriers are operated so as to return in synchronization with the timing of rotation of the constant interval forwarding device.

However, only the carriage 2 is shown as a representative in the drawing.

First, the A terminal 10a will be explained.

A deceleration device 20b is disposed in the section from the vicinity of the rope point 12b to the vicinity of the point 13b, and is configured to reduce the speed of the carrier 2 from the operating speed of the rope 1. In addition, in the section from the vicinity of point 14b to the vicinity of gripping point 15b, an accelerator 30

However, due to frictional force, the vehicle is sequentially decelerated in the direction of the arrow 24, and the deceleration is completed when it reaches near the position of the tire 21f.

The deceleration device 20b of the B terminal 10b is also a device disposed between the rope point 12b and the point 13b, and the tangential speed of the peripheral edge of the tire 21f on the most driven side is equal to the operating speed of the turning and forwarding device 50. The driving means 29b drives the driving means 29b.

Next, the accelerator 30a (30b) is for accelerating the carrier 2 from the vicinity of the point 14a (14b) to the vicinity of the gripping point 15a (15b), and for example, the device shown in FIG. 3 is used.

The specific configuration is similar to that of the deceleration device 20a (20b), but the moving direction of the carrier 2 is different.

To explain the accelerator 30a of the A terminal 10a, it moves along the rail 16a from near the point 14a to the gripping point 15a.

In this way, the rope gripping machine 3
is sequentially accelerated in the direction of arrow 34 by frictional force while rolling on the rail 16a with the running wheels 5a, 5b and in contact with the peripheral edges of the tires 31f, 31e, 31d, 31c, 31b, 31a, and near the tire 31a. to complete the acceleration.

The accelerator 30b of the B terminal 10b is also connected to the point 14b.
This is a device disposed between the vicinity and the gripping point 15b, and the tangential speed of the peripheral edge of the tire 31f on the most driven side is determined to be approximately equal to the 50 motion speed of the turning and forwarding device, and the driving means 39b Driven by.

For example, the one shown in FIG. 4(a) is used as the regular interval feeding device 40 disposed in the A terminal 10a.

The constant interval feeding device 40 has a flexible traction band 41 wound endlessly along a guide rail 42 and circulated in the direction of an arrow 48 by a drive wheel 43. In addition, the circulation path of the traction belt 41 is located at the point 13 as shown in FIG.

The route from near 3a to point 14a is taken along the rail 16a.

The traction belt 41 is equipped with a plurality of engagement means 44a, 44b, . The distance between the coupling means (for example, 44a and 44b, 44b and 44c, etc.)
・) is set for each constant value P. Therefore, the developed total length of the traction band 41 is set to be an integral multiple of P.

As the traction belt 41, for example, a chain can be used, and as the drive wheel 43, a sprocket wheel can be used, and as the engaging means 44a, 44b...44g, for example, a pin as shown in FIG. 4(b) can be used. Two opposing ratchets 46a and 46b are pivotally connected to 45a and 44b and are constantly biased in the directions of arrows 47a and 47b by springs (not shown).

Note that the driving wheels 43 are driven by a driving means 49, which will be described later.

The return and forwarding device 50 disposed in the B terminal 10b has the following structure as shown in FIG. 5(a).

The return and forwarding device 50 is configured such that a flexible traction band 51 is endlessly wound along a guide rail 52 and circulated in the direction of an arrow 57 by a drive wheel 53. In addition, the circulation route of the traction belt 51 passes through the vicinity of point 13b and the vicinity of point 14b, as shown in FIG.
In addition, the route from point 13b to near point 14b is taken along rail 16b.

The traction belt 51 includes engagement means 54a, 54b, and 54c for engaging with the suspension device 6 of the carrier 2 and returning the carrier 2.
. . , and the distance between one engaging means and the next engaging means (for example, 54a, 54b, and 54c).
) is the gap K required for the size of the suspension machine 6 to be engaged.
is set to a constant value Q at as short an interval as possible.

For example, a chain can be used as the traction belt 51, a sprocket wheel can be used as the drive wheel 53, and the engaging means 54a, 54b, 54c, etc. can be used, for example, as shown in FIGS. 5(b) and 5(c). As shown in the figure, the pin 55 connects the claw 56.
It is pivoted and engages with the suspension machine 6 by a claw 56, and is fed in the direction of the arrow 57. When engaging near point 13b, if the claw 56 and the suspension device 6 interfere, the claw 56 can escape around the pin 55 as shown by the chain line, so as to avoid interference during introduction. do.

Notwithstanding the above-mentioned examples, it is also possible to use a steel cable, a belt, etc. in addition to a chain as the traction band 51, and it is also possible to use a device equipped with a protrusion thereof as an engagement means.

The drive wheels 53 are driven by a driving means 59, which will be described later.

The forwarding devices, that is, the constant interval forwarding device 40 and the return forwarding device 50 respectively disposed in the terminals in the above description.
, reduction gears 20a, 20 disposed in each of the terminals.
In this specification, the accelerators 30a and 30b are collectively referred to as carrier operation equipment.

As mentioned above, it is equipped with transport equipment,
When operating these transport equipment, it is necessary to establish the following interlocking relationship with the operation of the cables.

First, in the A terminal 10a, the reduction gear 20a
is the driving means 29a, and the accelerator 30a is the driving means 39a.
The constant interval forwarding device 40 is driven by the driving means 49, and in the B terminal 10b, the deceleration device 20b is driven by the driving means 29b, the acceleration device 30b is driven by the driving means 39b, and the forwarding device 50 is driven by the driving means 59. and the respective driving means 29a, 39a, 49a
, 29b, 39b, 59, when the standard operating speed V of the cable 1 (the rotation speed N of the pulley 11a or 11b) is,
N1, N2, N, respectively, according to the required operating conditions of each equipment.
Set to 3, N4, N5, and N6.

However, when the operating speed of the cable changes to V'=k・V (rotational speed N'=k・N of pulley 11a or 11b),
Operating means 29a, 39a, 49a, 2 for transportation equipment
The rotation speeds of 9b, 39b, and 59 are N'1=k・N1, N'
2=k・N2, N′3=k・N3, N′4=k・N4,
It is necessary that N′5=k・N5, N′6=k・N6, that is, the operating means 29a, 39 of the transport equipment
The rotational speed of a, 49, 29b, 39b, 59 is the cable speed V
Alternatively, it is necessary to configure them so that they are always in a proportional relationship with the pulley rotation speed N and are operated in synchronization with each other.

Such conditions are necessary in order to maintain constant intervals in the carriage operation even when the cableway is operated with the operating speed V changed to a desired value.

In order to achieve such a relationship, it can be realized by configuring a mechanical or electrical interlocking relationship, and an example will be shown below.

First, the case of mechanical movement will be explained with reference to FIGS. 6(a) and 6(b).

FIG. 6(a) is a system diagram of connections for interlocking.

The cable 1 circulates between the pulley 11a and the pulley 11b, and
In the terminal 10a, the rotation is taken out from the pulley 11a, mechanically transmitted to the gearbox GA, and further branched from there, and the rotation speed is reduced or increased to the required number of rotations for each device, and the speed reduction device 20a, The rotation is transmitted to the accelerator 30a and the constant interval transfer device 40.

Similarly, at the B terminal 10b, the rotation is taken out from the pulley 11b, mechanically transmitted to the gearbox GB, and further branched from there, and the rotational speed is reduced or increased to the required number of rotations for each device, and the reduction gear 20b, The rotation is transmitted to the acceleration device 30b and the push-back feeding device 50.

FIG. 6(b) explains the above in more detail, including the arrangement relationship.

That is, at the A terminal 10a, the rotation of the pulley 11a is extracted and transmitted to the gearbox G using the chain transmission device CNA.
1A, and then connect gearbox G with transmission shaft S1A.
Connected to 2A, and branched from here to each device to transmit rotation. That is, transmission shaft S2A, gearbox G3A (driving means 2
9a) to drive the deceleration device 20a, and the transmission shaft S3A,
The accelerator 30a is driven through the gearbox G4A (driving means 39a), and the transmission shaft S4A and the gearbox G5A (
The constant interval feeding device 40 is driven via the driving means 49). For example, a propeller shaft is used for each transmission shaft S1A, S2A, S3A, S4A, and a gearbox G
1A, G2A, G3A, G4A, and G5A are used to change the direction of power transmission and to reduce or increase the rotation speed to a required number.

The B terminal 10b is also configured in exactly the same manner.

With this configuration, the number of rotations of the pulley 11a or 11b is in a proportional relationship with the operating speed of the cable 1, and therefore the operating speed of the carrier moving equipment is also in an interlocking relationship with the operating speed of the cable 1. can be maintained.

Next, another example of an electrically interlocking relationship will be described.

FIG. 7(a) is a system diagram of connections for interlocking, and
Figure (b) also shows the arrangement relationship. Pulley 1
A cable 1 circulates between 1a and a pulley 11b. The A terminal 10a is equipped with a roller RA that rotates following the cable 1, and by detecting the rotational speed of the roller RA, the cable speed detector DRA sends a signal corresponding to the cable speed to the controllers C1A, C2A, and C3A. sending. Speed reducer 20a
is driven by a variable speed electric motor M1A (driving means 29a), and a motor speed detector D1A is attached to the variable speed electric motor M1A to detect the rotational speed of the variable speed electric motor M1A and send a signal to the controller C1A. are giving feedback. The controller C1A compares the two input signals, and if there is a deviation, controls the variable speed electric motor M1A to make the rotation correspond to the cable speed. Similarly, the accelerator 30
In case a, the cable speed detector DRA and motor speed detector D
2A signal causes controller C2A to start variable speed electric motor M2A (
The driving means 39a) is controlled and driven, and also in the case of the constant interval feeding device 40, the controller C3A controls the variable speed electric motor M3A (driving means 49) according to the signals from the rope detector DRA and the motor speed detector D3A. It is controlled and driven.

The B terminal 10b is also configured in the same manner as described above, using rollers RB and rope speed detectors DRB.

In this way, even if the electrical interlocking relationship is configured, each device can follow the operating speed of the cable 1 and operate at a proportional speed.

The constant interval relationship of the method for moving a carrier at constant intervals according to the present invention, which is carried out using the apparatus configured as described above, will be explained.

The speed, carrier interval, and carrier time interval of the cable and transport device are as follows.

Speed of cable 1: V m/s Car interval in cable 1: S m Car interval in cable 1: T s Operating speed of fixed interval forwarding device 40: v1 m/s Car interval in fixed interval forwarding device 40 Carrier interval: s1 m Carrier time interval in fixed interval forwarding device 40: t1 s return forwarding device 50
Operating speed: v2 m/s Carrier spacing in the return and forwarding device 50: s2 m Cargo interval in the return and forwarding device 50: t2 Pitch of the engaging means 44 of the s constant interval forwarding device 40: P m Also, at the normal cable speed On the other hand, the operating speed of each layer equipment is set to be slow, but the speed ratio is as follows.

i1 V/v1 i2 V/v2 When operating, V, v1
, v2, the preset relationship is always maintained as V i1·v1=i2·v2 . In addition, the other deceleration devices and acceleration devices also maintain interlocking relationships in operation.

Furthermore, if one carrier 2 is engaged with each of the engaging means 44a, 44b, . =P, which is equal to the pitch of the engagement means 44. The carrier time interval at this time is t1=s1/v1.

Next, the carriers 2 pass through the acceleration device 30a, grip the cables 1, and depart one after another onto the cableway. Preceding in route 1,
The relationship between the following carriages is such that the carriage time interval T is maintained as T=i1, and the carriage interval is S=V・T=i1・v1・T=i1・s1, that is, the carriage interval s1 in the constant interval forwarding device 40 The distance is i1 times that of .

Next, the carrier reaches the B terminal 10b, wanders, enters the deceleration device 20b, and decelerates, and the return and forwarding device 50
Since a plurality of engagement means 54a, 54b, . be done. Since the carrier is transported without delay in this manner, no time delay occurs, and therefore the carrier time interval is maintained at t2=T=t1. And the carrier interval is s2=v2・t2(1/i2)(V・t)=(1/i
2) S or s2(i1/i2)(v1·T) =(i1/i2)s1.

Next, the carrier 2 is sent back and guided by the return and forwarding device 50, accelerated by the accelerator 30b, grips the cable 1, and departs into the cableway toward the A terminal 10a.

The carrier time interval between the preceding and following carriers on cable line 1 is T = t2
= t1, and the carrier interval is S=V・T=i2(v2・t2)=i2・s2 or S=i1(v1・T)=i1・s1.

After circulating in this way, the carrier returns to the A terminal 10a,
Deceleration is performed by letting the cable 1 wander. At the point where deceleration is completed, that is, near point 13a in FIG. 1, the carrier becomes slow v1 or stops.

As mentioned above, during the circulation of the carrier, the time interval between the preceding and following carriers is maintained at T = t1 = t2, and when the carriers arrive at the A terminal 10a, the time interval is constant and the time interval between the carriers is constant and the time interval between the preceding and following carriers is maintained. It slows down or stops.

Here, due to the rotational operation of the constant interval feeding device 40, the engaging means 44 is moved from the rear of the carrier 2 by the arrow 4 in FIG. 1 or 4.
It advances in eight directions, catches and engages with the carrier 2, and is sent again. The subsequent carriers are also simultaneously captured and engaged by the engaging means that advance one after another, and are sent to the departure side again, continuing the circulation operation at regular intervals.

In the above configuration, it is usually sufficient to set v1=v2, but due to the relationship between the length of the cableway and the desired interval between the carriages, if the waiting time for the engaging means 44 to track the carriage 2 that has arrived near the point 16a is long, If the operating speed v2 of the turn-back device 50 is set somewhat higher or lower, the B terminal 10
Since it is possible to advance or retard the phase of the carrier moving from b to the A terminal 10a, the timing of delivery and reception can be adjusted so that the engaging means 44 tracks and engages the carrier that has completed deceleration or stopped near point 13a. can be adjusted optimally.

In order to simplify the explanation, the present invention includes each reduction gear 20a, 2.
0b, each accelerator 30a, 30b was omitted in the explanation,
Even if these devices are taken into account, as long as the interlocking relationship of operations described above is maintained, the basic relationship between the carrier spacing and the carrier time limit will remain unchanged.

Next, a case where the operating speed V of the cable is changed or changed will be described.

As mentioned above, the operating speeds of the cable and the transport equipment are always linked to maintain a proportional relationship, so the speed V when the cable speed becomes, for example, 1/2 of the standard speed V
', v1'v2', carrier time intervals T, t1, t2, and carrier intervals S, s1, s2 are as follows.

V'=V/2, v1'=v1/2, v2'=v2/2T
'=2T, t1'=2t1, t2'=2t2S'=S,
If s1'=s1 and s2'=s2, that is, the speed is set to 1/2, the time interval between the carriages will be doubled, but the interval between the carriages will not change and will remain constant.

This relationship is always maintained without changing the carriage interval even when changing to other speeds.

No matter how the operating speed of the cable is changed in this way, the constant spacing relationship of the carriers that started with the constant interval regulation performed by the constant interval forwarding device is maintained during one cycle of the carrier, and the constant spacing relationship is maintained again during one cycle of the carrier. It returns to the interval forwarding device, and this operation is repeated one after another to continue regular interval operation.

The effects and features of the method and apparatus for operating an automatic circulation type cableway carrier at regular intervals according to the present invention as described in detail above are as follows.

(A) At the A terminal 10a, the carriages circulate at a spacing of s1, on the roadway at a carriage interval of S, and at the B terminal 10b at a carriage interval of s2, and the progress of the carriage is similar to the circulation of carriages on a fixed circulation cableway. , there is no disturbance such as stagnation, and continuous and smooth circulation operation is possible.

(b) The relationship in (a) above is always maintained even if the operating speed is changed.
