Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is applied to gripping a gripping machine in a double-type single-track automatic circulation cableway that circulates and transports two parallel towlines. The present invention relates to a device for performing gripping by approximately synchronizing even when there is a speed difference between the supporting lines, and to a device for performing a safety measure when the speed difference is larger than a predetermined value.

[Prior Art] An automatic circulation cableway is a grip that suspends and circulates an endless hauling line between pulleys arranged at terminals at both ends (referred to as a stop. The same applies hereinafter). The rope is gripped by the tow line, and the transport is carried out along with the circulation operation of the tow line for transporting, and it has recently been remarkably frequently used for transporting skiers and sightseeing in mountainous areas. This is generally known.

Here, conventionally, only one line of the tow line that also functions as a tow line for supporting and suspending the carrier is used, and the capacity of the carrier is 4 to 8
People have been generally practiced. However, in order to further increase the transportation capacity, a cableway facility of a type in which a larger number of carriers are used and load lines are shared by using two tow lines in parallel has recently been proposed and proposed. This type of cableway equipment is a double mono cable cableway (DM
C), double-type single-track automatic circulation type cableway, double-branch towline automatic circulation type cableway, etc., but unified terms have not been established.

In the present specification, the following description is made using the term of double-type single-track automatic circulation type cableway.

In the conventional single-track automatic circulation type cableway, the transporter moves slowly along the rail installed in the terminal while passengers get on and off, and then is accelerated by the acceleration transfer device until it reaches the speed equal to the speed of the towline. After this, the rigging machine is designed to grab a single-line tug and depart into the cableway line. As the above-mentioned acceleration transfer device, a device in which a large number of pneumatic rubber tire wheels are arranged side by side to push the gripping machine at the peripheral portion is generally used.

In such a configuration relationship, in the case of a single-track automatic circulation type cableway, it is necessary that the speed of the towing cord and the speed of the gripping machine match at the time when the above-mentioned gripping operation is performed, If there is a difference in speed, a relative stumbling may occur, which may cause wear of the towing line or the grip of the gripping machine, or may impair the riding comfort. On the other hand, as a device for synchronizing the speed of the towed line and the speed of the transfer device, for example, the actual exploitation Sho 57-113269
It has been proposed in Japanese Laid-Open Publication "Chairway Departure Arrival Arrival Pushing Device".

On the other hand, in the case of the double-type single-line automatic circulation type cableway, two strut cords are circularly moved in parallel in the cableway line so that the gripping machine grips two parallel strut cords simultaneously or commonly. However, the basic operation in the terminal is equivalent to that of the conventional single-track automatic circulation type cableway. In addition, the point that it is necessary to synchronize the speeds of the gripping machine and the towing lines is basically the same when starting the gripping machine.

FIGS. 5A, 5B, 5C, 5D, 5E, and 5C exemplify the circulation structure of the towlines that can be or may be used in the double-single-line automatic circulation cableway.

FIG. 5A shows a driving pulley 52 driven by a common driving shaft 53.
a, 52b and tension pulleys 55a, 55b independently pivoted to the tension shafts 56a, 56b, respectively, are used as the driving pulley 52a and the tension pulley 55a.
A tow cable 57a circulates between the drive pulley 52b and the tension pulley.
Another towline 57b circulates with 55b. Tension axis 56
The a and 52b are separately tensioned by tensioning means (not shown) such as a weight or a hydraulic device. In the cableway line 58, gripping machines 59, 59 ...
Have a common grasp.

FIG. 5 (a) shows a driving pulley 62 commonly driven by a driving shaft 63.
a, 62b, and tension pulleys 65a, 56b pivotally attached to a common tension shaft 66 so as to be respectively rotatable, using a single strut cable 67
In which the tension shaft 66 is tensioned by a tensioning means (not shown). In the cableway line 68, the tow lines 67 and 67 formed by a double loop are arranged in parallel, and the lanyards 69, 69, ... This support line circulation structure has been proposed, for example, in Japanese Patent Laid-Open No. 62-17058 “Automatic Circulation Cableway Double Strand Circulation Structure”.

FIG. 5C shows a driving pulley 72a driven by a driving shaft 73a,
A driving pulley 72b driven by a driving shaft 73b is used, while tension pulleys 75a and 75b pivotally attached to the tension shafts 76a and 76b are used, and a tug 77a is attached to the driving pulley 72a and the tension pulley 75a. It is circulated, and a tug 77b is provided between the driving pulley 72b and the tension pulley 75b.
Is circulated, and the tension shafts 76a and 76b are separately tensioned by tensioning means (not shown). Here, the driving pulleys 72a and 72b are separately driven, but they are electrically controlled at uniform speed. In the cableway line 78, the gripping machine 7 shown schematically
9,79 ... commonly grips two parallel lines 77a, 77b.

[Problems to be Solved by the Invention] Although various circulating configurations of the towing lines other than those illustrated here are conceivable, any two-row parallel towing lines may be used. However, moving at a uniform speed in synchronization is a necessary prerequisite.

On the other hand, referring to FIGS. 5 (a), (b), and (c) of the above example, the cases of the driving pulleys 52a, 52b and the driving pulleys 62a, 62
In the case of 2b, since they are driven by the same driving shaft 53 or 63, they rotate in the same phase. Also the prime mover
Since 72a and 72b are also controlled in uniform speed, they rotate in the same phase. Therefore, at least near the prime mover, it is fully expected that the two parallel tow lines will travel at a uniform speed.

On the other hand, on the tension pulley side, it is conceivable that the uniform speed condition is easily disturbed by disturbance in the cableway line that is remote from the prime mover position, but as shown in Fig. 5 (a) (a) (c). In the case where the gripping machines in the cableway line are gripping the towing lines in parallel with each other, the towing lines are in a black state, and as a result, the towing lines can move at the same speed. I am helping to be done. Also, from the operation record of the conventional three-wire automatic circulation type cableway, there is no particular problem of the speed difference between the towlines which is harmful. It is considered that there are few opportunities to cause harmful speed difference.

However, in the case of limited conditions, for example, in the case of an initial carrier when a gripping machine or a carrier is not arranged in the cableway line, this speed difference may occur. In such a case, it is necessary to eliminate the wear of the support cord or the gripping device gripping part as much as possible between the gripping device and the support cord.

If a particularly large speed difference occurs between the two tow lines,
Even if some kind of driving abnormality occurs, in the case of the double-type single-track automatic circulation type cableway, the distance between the two support lines is large. Couples may act on the spinners, causing spin motion in general.

As described above, although the double-type single-track automatic circulation cableway is often basically equal to the conventional single-track automatic circulation cableway, there are problems inherent to the two-support tug. However, since this model has almost no construction record so far, the problem has not been examined or dealt with so far.

The present invention has been made in response to the above circumstances,
In a double-type single-line automatic circulation cableway that uses two strut cords in parallel, even if a speed difference occurs between the two strut cords that are in parallel, A device for starting the gripping machine or transporter at a synchronized speed that causes less wear, and taking a measure such as temporarily waiting for the departure of the gripping machine or transporter when the speed difference is particularly large to ensure departure safety. The purpose is to provide.

[Means for Solving the Problems] In response to the above-mentioned object, the present invention relates to a first invention relating to two configurations or devices which are correlated with respect to a common technical problem concerning the starting safety of a carrier of a double-type single-track automatic circulation type cableway. It consists of the second invention. The first aspect of the invention is to accelerate and transfer a gripping device or a carrier with a suitable synchronization speed by evaluating both speeds even if there is a speed difference between two parallel tow lines of a double-type single-line automatic circulation type cableway. It is related to the device. A second aspect of the invention relates to a device capable of performing a necessary safety process according to the step of the size when the speed difference of the supporting lines is large.

That is, according to the first aspect of the present invention, a towline is wound between pulleys of terminals at both ends and circulates, and two tow lines are respectively stretched in parallel on both reciprocating lines of a cableway line, and a carrier is suspended and the above two lines are lined up. Using a gripping machine that grips the supporting cords in common, the gripping machine is accelerated by a transfer device at one of the terminals and starts by gripping the supporting cords, and then the other of the terminals. In one aspect, in the terminal in the double-type single-track automatic circulation type cableway, which releases the tow lines and arrives at a reduced speed, the terminals are detected by detecting the speed of each of the parallel tow lines.

It is a thing.

According to the second aspect of the present invention, the towline is wound between the pulleys of the terminals at both ends and circulates, and the two tow lines are stretched in parallel on each of the two reciprocating lines of the cableway line. Using a gripping machine that grips the supporting cords in common, the gripping machine is accelerated by a transfer device at one of the terminals and starts by gripping the supporting cords, and then the other of the terminals. In one aspect, in the terminal in the double-type single-track automatic circulation type cableway, which releases the tow lines and arrives at a reduced speed, the terminals are detected by detecting the speed of each of the parallel tow lines. First to output rope speed signal sva or svb

It is configured as a device.

[Operation] First, the operation of the starting speed tuning apparatus of the first invention of the present invention is as follows. The rope speed detector detects the speed of each of the two parallel wires and outputs a towing speed signal. Next, the transfer speed calculation means substitutes the tow cord speed signal into a predetermined relational expression to calculate and outputs the transfer speed signal. The control means outputs a control signal based on the transfer speed signal to control the rotation of the variable speed electric motor. The variable speed electric motor is provided in the transfer device and accelerates and transfers the gripping machine from a slow speed to a gripping speed.
Here, for example, if the relational expression given in advance to the transfer speed calculation means is defined as "the average speed of the two-row parallel tug ropes", this device takes both the tug rope speeds into consideration. Accelerate the rigging machine to match the average speed of.

Next, the operation of the starting safety device of the second invention is as follows.

The rope speed detector detects the speed of each of the two tow ropes and outputs a tow rope speed signal. Next, the speed difference calculating means calculates the difference between the tow cord speed signals and outputs the speed difference signal to the speed difference comparing means. On the other hand, the specific speed difference generating means sends the specific speed difference signal corresponding to the speed difference for which necessary safety measures are to be performed, to the comparing means, and the comparing means changes the value of the speed difference signal to the value of the specific speed difference signal. If so, a specific safety signal is output, which is sent to the central monitoring device of the cableway for safety measures such as operation stop. If the value of the speed difference signal does not correspond to the value of the specific speed difference signal, the operation of the tug line is continued.

[First Embodiment] This embodiment relates to a specific configuration of the starting speed tuning apparatus of the first invention of the present invention. FIG. 1 shows the entire double type single-track automatic circulation cableway provided with the apparatus of the present invention. Shows.

Driving pulleys 2a, 2b are fixed to the driving shaft 3 of the driving terminal 1, while tensioning pulleys 5a, 5b are pivotally mounted on the tensioning shafts 6a, 6b of the tensioning terminal 4, respectively. Driving pulley 2a
A towing line 7a circulates between the tension pulley 5a and the tension pulley 5a.
A tow line 7b circulates between the tension pulley 5b and the tension pulley 5b. In the cableway line 8, the two tow lines 7a and 7b are stretched in parallel, and the gripping machine 9,9 shown in the diagram is a two-line tow line 7a, 7b.
Have a common grasp. A transfer device 10 for accelerating the departure of the gripping machine and a transfer device 11 for decelerating the arrival are provided in the tension terminal 4, and similarly, the transfer devices 12, 13 are also provided in the driving terminal 1. There is. This cord circulation configuration is
It is basically equivalent to the one used in the description of the prior art of FIG.

In this embodiment, the apparatus of the present invention is provided in the tension terminal 4 having the cableway structure shown in FIG. 1 as shown in FIG. However, regardless of the present embodiment, the device of the present invention can also be adopted in other cableway configurations, for example, in the case of FIGS. 5A and 5C. Moreover, although it is suitable to use for a tension terminal, it is needless to say that it can be applied to a driving terminal or a driving tension terminal if necessary.

FIG. 2 shows the configuration and connection relationship of each device in the tension terminal 4 corresponding to FIG. 1. The starting tuning device 30 according to the first invention and the starting safety according to the second invention of the present invention. Both device 40 is shown.

On the departure route 14 indicated by the arrow of the gripping machine (not shown) in the tension terminal 4, the gripping machine is almost towed from the slow speed.
A transfer device 10 is provided which accelerates to the speed of 7a, 7b. Near the position where this accelerated transfer is completed, the rigging machine pulls the cord.
Grip 7a and 7b and start in the direction of cableway line 8. Transfer device 1
A friction transfer system having a large number of rubber tire wheels arranged side by side can be used for 0, but in addition to this, for example, Japanese Patent Application No. 62-
A configuration using a linear motor proposed in No. 192107 “carrying device for ropeway and gripping machine transfer device” can also be used.

First, the starting tuning device 30 will be described with reference to FIG.

In the vicinity of the transfer device 10 at the terminal 4 and towed
Along the passage of 7a and 7b, the tow cord speed detector 20a (Dr
a) and 20b (Drb) are provided. Here, the support cord speed detector 20a (Dra) is for detecting the speed of one support cord 7a, and the support cord speed detector 20b (Drb) is the speed of the other support cord 7b. Is for detecting. Various types of support cord speed detectors 20b (Dra) or 20b (Drb) can be used. Here, the detection roller 21a or 21b is brought into contact with the support cords 7a or 7b, respectively, and the scanning speed is increased. A rotating device is used to convert the rotation into an electric signal and send it to the transfer velocity calculating means CVM as the support cord velocity signals sva and svb. When a required signal is shared for the departure safety device 40, which will be described later, the support line speed signals sva and svb are simultaneously branched and sent to the speed difference calculating means CDM.

Next, the transfer speed calculation means CVM causes the rope speed signal sva, s
Input vb, and based on this, perform a calculation according to a predetermined predetermined relationship or functional expression to generate a signal corresponding to the required operating speed of the transfer device 10, and output it as a transfer speed signal svo to the control means CNT. To do. Here, a predetermined relationship or functional expression for performing the above calculation will be described later.

Next, the control means CNT outputs a control signal sc for controlling the rotation of the variable speed electric motor M based on the transfer speed signal svo. On the other hand, the electric motor speed detector DMV attached to the variable speed electric motor M detects the rotation speed of the variable speed electric motor M and feeds it back to the control means CNT as a feedback signal sf. The control means CNT is the transfer speed signal svo,
Both of them are compared with the feedback signal sf, and if there is a deviation, the variable speed electric motor M is controlled to maintain the required operating speed of the transfer device 10.

Next, the operation of the starting tuning device 30 of the first invention will be described with reference to FIG.

First, when the ropeway is driven and the towing lines 7a and 7b move, the towing line speed detection devices Dra and Drb detect the towing line speeds Va and Vb, respectively, and thereby the towing line speed signals sva and svb, respectively.
Is output.

The next transfer velocity calculating means CVM is the above-mentioned tow cord velocity signal sva, s.
The transfer speed signal svo is output by performing an operation from vb according to a predetermined relationship. Here, the predetermined relationship is generally defined as represented by svo∝f (sva, svb), that is, the transfer speed signal svo
Is determined so as to be proportional to the function of the towing speed signals sva and svb. More specifically, if svo∝ (sva, svb) / 2 is set, the operating speed of the transfer device 10 with the average speed (Va + Vb) / 2 of the speeds Va and Vb of the tow lines 7a and 7b as the target. Can be set. If necessary, as an example, the operating speed of the transfer device 10 can be determined by targeting a speed closer to the higher speed than the average speed as described above. However, for the purpose of speed synchronization, the operating speed of the transfer device 10 is
It is appropriate to set the speed within the range of Va to Vb of a and 7b.

The transfer speed signal svo determined in this way is controlled by the control means C.
Output to NT.

Based on this, the control means CNT outputs the control signal sc to the variable speed electric motor M for control. On the other hand, the electric motor speed detector DMV attached to the variable speed electric motor M sends out the rotational speed n of the variable speed electric motor M and feeds it back to the control means CNT as a feedback signal sf based on this. In the control means CNT, the transfer speed signal svo and the feedback signal sf are compared so that (svo-sf) → 0, that is, when there is a deviation, the variable speed electric motor M is controlled to control the desired rotation speed. To get it.

The transfer device 10 is driven by the variable-speed electric motor M to accelerate and transfer the gripping device or the carrier, and the gripping device grips the towing line to start the carrier.

By operating in this way, even if there is a difference in speed between the two tow lines 7a and 7b, the transfer device 10 is operated and controlled to a desired speed that has little effect on the tow lines, gripping machine, or carrier. can do.

[Second Embodiment] Next, an embodiment relating to a specific configuration of the departure safety device 40 of the second invention will be described again with reference to FIG.

First, the arrangement structure of the tow lines 7a, 7b, etc. in the terminal 4 is as described above, and the tow line speed detector Dr.
The explanation about a and Drb is also as described above. The tow cord speed detectors Dra and Drb output tow cord speed signals sva and svb corresponding to the speeds of the tow cords 7a and 7b, respectively.

As described above, in the present embodiment, the tug speed signal sva, svb is shared with the departure speed tuning device 30 and the departure safety device 40, but may be shared in this way, or
It goes without saying that the tow cord speed detectors Dra and Drb may be provided independently of each other.

Next, the speed difference calculation means CDM inputs the towing rope speed signals sva and svb, and performs a calculation by this to generate and output the speed difference signal sd.

The next speed difference comparison means FVM inputs the speed difference signal sd and the specific speed difference signals sp1, sp2, ... For comparison. The specific speed difference signals sp1, sp2 ... Are output from the specific speed difference generating means SPM to the speed difference comparing means FVM in a single-step single type or a plurality of multi-step steps.

The specific speed difference signals sp1, sp2 ... Are predetermined according to the mutual values of the tow lines 7a, 7b. In the speed difference comparison means FVM, the specific speed difference signals sp1, sp2 are compared step by step with the speed difference signal sd for each step, and if the set conditions are met for each step, the specific security signal ss1 or ss2 ... is output to the control device for the whole cableway equipment or the central monitoring device CIP to issue an alarm,
Actions such as operation stop are taken. Alternatively, no signal is output at each stage when the set condition is not satisfied.

Next, the operation of the safety device 40 will be described with reference to the flowchart of FIG.

As described above, the tow cord speed detectors Dra and Drb are the tow cords, respectively.
The speeds of 7a and 7b are detected and the tow cord speed signals sva and svb are output. Next, in the speed difference calculation means CDM, the speed difference signals sva and svb are used for calculation, and the speed difference signal sd is output based on the calculation. That is, here, sd∝ | (sva-svb) | is calculated to calculate the speed difference, and the speed difference signal sd proportional to the absolute value is output. As far as the purpose of this device is concerned, it is possible to use the absolute value as described above, but it is necessary to also know which speed of the tug lines 7a, 7b is higher for other purposes. Is required to be a positive and negative display, not an absolute value.

The speed difference signal sd thus output is input to the speed difference comparison means FVM. On the other hand, the specific speed difference generating means SPM
, A predetermined specific speed difference signal sp1, sp2 ... Is generated in a single step or a plurality of steps and is output to the speed difference comparison means FVM. In the speed difference comparison means FVM, the towed speed difference for each step is generated. When the conditions are met as compared with the signal sd, the specific security signals ss1, ss2 ... Are output respectively.

In the embodiment shown in FIG. 4, the specific speed difference signals sp1, sp2,
Three types of sp3 are used in three stages. Depending on the magnitude of the speed difference between the stanchions 7a and 7b, a signal of a value corresponding to each critical value required for different treatment is generated. Has been done.

If this is shown by a concrete example, the specific speed difference signal of the third stage
sp3 corresponds to the case where the speed difference between the tow lines 7a and 7b is abnormally large and is not only unsuitable for the departure of the carrier, but is large enough to cause some accident. Specified speed difference signal sp3 is compared with the speed difference signal sd by the speed difference comparison means FVM, if sd ≧ sp3, the specific security signal ss3 is output to the central monitoring CIP, and the central monitoring device CIP uses the cableway Try to stop all. At this time, of course, the transfer device 10 is also stopped accordingly.

Next, the specific speed difference signal sp2 of the second stage is determined according to this speed difference when the speed difference between the tow lines 7a and 7b is slightly large and it is slightly unsuitable for starting the carrier. The speed difference signal sp2 is compared with the speed difference signal sd by the speed difference comparison means FVM, and if sd ≧ sp2, the specific security signal ss2 is sent to the central monitoring device CIP.
In this case, the central monitoring device CIP can take measures such as temporarily stopping the transfer device 10 and temporarily waiting for the departure of the carrier. However, if the standby is continued for a long time, the subsequent carrier is congested and the operation is disturbed. In this case, additional measures are required.

Further, the specific speed difference signal sp1 of the first stage is generated although the speed difference between the tow lines 7a and 7b is small. The determined specific speed difference signal sp1 is compared with the speed difference signal sd by the speed difference comparison means FVM, and if sd ≧ sp1, the specific security signal ss1
Is output to the central monitoring device CIP, and in this case, for example, this information can be shown on a display for driving monitoring to take action such as calling the driver's attention.

The above is an example of each condition when the specific speed difference signals sp1, sp2, sp3 are set to three stages, but in actual application, this stage is not limited to three stages and may be set as necessary. Needless to say, it is possible to set, and the comparison condition and the treatment can be set as necessary.

In the above description, the rope speed detecting devices 20a and 20b are roller type ones that follow the towing lines 7a and 7b, but signals should be extracted from the rotation of the tension pulleys 5a and 5b. Is also possible. It is needless to say that each of the above signals can be analog or digital, and any suitable signal can be used, and AD conversion and DA conversion can be performed if necessary.

Further, as described above, it is also apparent that the variable speed electric motor M used in the transfer device 10 can be a linear motor that directly transfers a gripping machine in addition to an ordinary rotating machine.

[Effects of the Invention] First, the effects of the starting speed tuning device for the double type single track automatic circulation type cableway according to the first aspect of the present invention will be described. Even in the conventional single-line automatic circulation cableway of a single towing line, when the gripping device or carrier is to be departed, the transport device that accelerates in synchronization with the speed of the towing line accelerates the gripping device or carrier and It was supposed to be squeezed and departed so that there was no relative speed difference with the gripping machine. This conventional device can basically be used in the case of a double-type single-track automatic circulation cableway, but if there is a speed difference between the tows for some reason, one of the tows will be synchronized. However, it does not tune to the other side, which causes relative slippage.

According to this device, when there is such a speed difference, it is possible to detect the velocities of both support lines and set the tuning speed correspondingly. If it is determined that the average speed of the tow lines is set, the gripping machine has an approximate speed between both of the tow lines, and the grip can be performed stably with less slippage. Therefore, it is possible to reduce the abrasion of the towed lines and the grip of the gripping machine.

Next, the starting safety device for a double-type single-track automatic circulation type cableway according to the second invention of the present invention obtains a speed difference from the speeds of the two tow lines, and, for example, alerts when the speed of the tow line or temporarily leaves the carrier. It is possible to take safety measures such as waiting or stopping cableway driving.

When gripping is performed with a relatively large speed difference between the two tows, the distance between the tows is generally large in the case of the double-track single-line automatic circulation cableway, so yawing or spin motion of the carrier is performed. However, this device can prevent the start of the carrier when it is not appropriate.

However, such a large speed difference occurs when a special abnormal situation occurs in the cableway, etc., and in such a case, another safety device of the main task to detect this is naturally required. Although it takes action to stop the operation, etc., even in such a case, if it is detected by this device as a difference in the towline speed due to the first cause, this device is a backup device for the safety device of the main task. It is still effective.
