BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a traversing platform which is used as a stop for cableway equipment such as a crossing cableway and is commonly used as a carriage for both reciprocating tracks.

[0002]

2. Description of the Related Art As a typical example of a cableway facility for transporting by transporting a carrier along two-way ropes stretched at an elevated position, there is an articulated cableway. In the cableway, landings or platforms for the respective vehicles are fixed in parallel at the stops at both ends corresponding to the vehicles that operate on both the round-trip lines. However, such facilities are generally large-scale, and there are cases where it is economically difficult to install the facilities, particularly in steep terrain.

As one measure for solving such a problem, a configuration of a "trailing type platform device for cableway" filed on May 29, 1993 by the same applicant as the present application has been proposed. I have. In this traversing platform device for cableways, a platform provided with a carry-in entrance that almost conforms to the shape of the carrier is used as a platform for passengers to get on and off at the stop, and at the ground or in a fixed position. Is provided with traversing guide means, and the platform is driven by traversing drive means provided with an electric motor or the like so as to be able to traverse two positions between both reciprocating lines. In addition, when the carriage arrives at one side of the reciprocating line at the stop, the platform is positioned on one side of the traversing path of the traversing guide means, the arrival of the carriage is stopped here, and the passenger is treated for getting off and getting on. Let them do it. Next, after the carriage has departed to the cableway, the traversing drive means is driven, the platform is guided by the traversing guide means, traversed to the other end of the traversing guide means and stopped at a predetermined position, and the carriage on the other side is moved. It is intended to be accepted.

However, since such a traversing platform device is commonly used for both reciprocating carriages, it is necessary to ensure that the platform switching operation is correctly completed when the carriage is received. Especially necessary from. If the switching operation is not proper, there is a danger or inconvenience that the arrival carrier collides with the platform, or the carrier enters and arrives when the platform is not prepared and passengers cannot get on and off. The purpose of the present invention is to solve such a problem and to provide a safety device that allows a carriage to enter a stop only when the traversing platform is correctly traversed. .

In the cableway equipment, a platform detector that detects the position of the platform and outputs a platform signal, a carrier detector that detects the location of the carrier at a stop and outputs a carrier signal, and a passage of the carrier in an operation line. A passage detector that detects and outputs a passage signal, and a control unit that inputs the platform signal, the carrier signal, and the passage signal to control the traversal of the traversing platform and intermittent operation of the carriage. It is configured as a traversing platform safety device.

[0006]

n, a traversing command signal sdpn for issuing an operation command to the traversing drive means 22n of the traversing platform 20n is output from the control means CON. Further, a cable drive command signal sdc for instructing the drive of the pulley 6n or the towing cable 7 to be intermittent is output from the control means CON to the cable drive device 8. This control means CON is configured using cpu or the like.

Next, the operation or operation of the present apparatus will be described with reference to FIGS. 2 to 3 and FIGS. FIG.
FIG. 5 is a flowchart showing the operation of the transporter and the traversing platform, FIG. 5 is a flowchart showing the operation of each detector, and FIG. 6 is an operation diagram of each detector.

First, in FIG. 2, the traversing platform 20m of the stop 2m is located on the A-line side, and the transporter 10a is stopped here. Further, the traversing platform 20n of the stop 2n is located on the B line side, and the transporter 10n is stopped here. This state corresponds to the state of “A” in FIGS. 4, 5 and 6. At the stop 2 m, the platform detector Pma on the A-line side detects the “location” of the traversing platform 20 m and outputs the platform signal spma. , And the carry detector Cma detects the “location” of the carry 10a and outputs the carry signal scma. In addition, the platform detector Pmb on the B line side detects “absence” of the traversing platform 20m, and the carrier detector Cmb detects “absence” of the carrier 10b. on the other hand,
At the stop 2n, the platform detector Pnb on the B line side detects the “location” of the traversing platform 20n and outputs a platform signal spnb, and the carrier detector Cnb detects the “location” of the carrier 10b and performs Signal s
cnb is output. Further, the platform detector Pna on the A-line side detects "absence" of the traversing platform 20n, and the carrier detector Cna detects "absence" of the carrier 10a. This state corresponds to “A” in FIG.
Pma = 1, Pmb = 0, Pna = 0, Pnb
= 1 and Cma = 1, Cmb = 0, Cna = 0, Cnb
= 1. The states of the pass detectors Lma, Lmb and Lna, Lnb are all returned to zero as Lma = 0, Lmb = 0, and Lna = 0, Lnb = 0. Here, a state in which each detector detects a detection target and outputs a signal is indicated by “1”, and a state in which no signal is output is indicated by “0”. In the operation diagram of FIG. 6, the horizontal axis indicates the transition of time, and the operation state of each detector is shown. The hatched portion indicates the signal output state "1". I will respond.

Such a state is set as an initial state and the transporter 1
Departure or departure of 0a, 10b is performed. Here, when the departure of the transporters 10a and 10b is performed as shown in "A" in FIG. 4, the transporter detector Cm as shown in "A" in FIGS.
Since a and Cnb indicate that the transporter 10a or 10b is “absent”, the detection of “present” is stopped, and the transporter signals scma and scn are output.
b is no longer sent, that is, the state of the carrier detector Cma changes from 1 to 0, the state of the carrier detector Cnb also changes from 1 to 0,
Each is switched.

Next, as described with reference to FIG. 2, a passage detector Lma is provided on the A-line side at a place where the carriage passes near the stop 2m, and a passage detector Lmb is provided on the B-line side.
In addition, a passage detector Lna is provided on the A-line side also at a place where the carriage passes near the stop 2n, and a passage detector Lnb is provided on the B-line side. Detect and output the passing signal. That is, the transporter 10
When a and 10b progress, corresponding to "U" in FIG.
In (c), the passage detector Lma detects the passage of the carrier 10a on the A line side, the state of the carrier detector Lma is switched from 0 to 1, and a passage signal slma is output, and the B line side The passage detector Lnb detects the passage of the carrier 10b, the state of the passage detector Lnb is switched from 0 to 1, and a passage signal slnb is output.
Sent to

On the other hand, in the control means CON, "D"
, Cma = 0, Cnb = 0, and Lma = 1, L
It is allowed to proceed to the next step in the flow of FIG. 5 on condition that nb = 1. That is, Cma = 0, Cnb
= 0, the transporters 10a, 10b have completed the departure from the traversing platforms 20m, 20n, and under the condition of Lma = 1, Lnb = 1, both the transporters 10a, 10b are enough from the stop 2m or 2n. It is determined that it is possible to traverse the traversing platform in the next step.

As described above, when the transporters 10a and 10b reach the position sufficiently far from the stop 2m or 2n and the traversing platforms 20m and 20n can traverse, as shown in FIG. When the traversing command signals sdpm and sdpn are output from the control means CON, the traversing operation of the traversing platforms 20m and 20n shown in FIG. 4 is executed. That is, at the stop 2m as shown in FIG. 2, the traversing platform 20m is guided along the guide rails 24 and 25 from the A-line side by the driving of the traversing drive means 22m, and switches to the B-line side as shown by a chain line. . And in the stop 2n, the traversing drive means 22n
, The traversing platform 20n is guided along the guide rails 24 and 25 from the B-line side, and is switched to the A-line side as shown by a chain line.

When this switching operation is completed as shown in FIG. 4 "f", as shown in FIG. 5 "f", at the stop 2m, the platform detector Pmb becomes the traversing platform 20m.
Is detected as “present”, the state of the platform detector Pmb is switched from 0 to 1, and the platform signal spmb is output. On the other hand, the platform detector Pma detects that the traversing platform 20m is “absent” and detects the platform detector Pm.
The state of a changes from 1 to 0. Similarly, at the stop 2n, the platform detector Pna detects that the traversing platform 20n is "present", and the state of the platform detector Pna changes from 0 to 1 to output the platform signal spna. , The platform detector Pnb detects that the traversing platform 20n is “absent”, and the state of the platform detector Pnb changes from 1 to 0.

During this time, the transporter 10a further travels in the operation line in the direction of arrow 4, and the transporter 10b also travels in the operation line in the direction of arrow 5. When the transporters 10a and 10b approach the vicinity of the other stop 2b or 2a, they pass through the position of the passage detector Lna or Lmb, and the passage is detected as indicated by "" in FIG. That is, in response to "g" in FIG. 4, in "g" in FIG. 5, the passage detector Lna detects the passage of the A-side carrier 10a, and the state of the passage detector Lna changes from 0 to 1.
And the passing signal slna is output, the passing detector Lmb detects passage of the B-side carrier 10b, and the state of the passing detector Lmb is switched from 0 to 1 to pass the passing signal slna. slmb is output and sent to the control means CON.

On the other hand, the control means CON confirms that Pna = 1 and Pmb = 1, that is, that the switching of the traversing platforms 20m and 20n has been completed, as shown in FIG. As a condition, the process proceeds to the next step "K" in the flow of the figure, and entry to the stop 2n or 2m is permitted. However, if the condition is not satisfied, the flow branches to the right side of the flow of the figure. I do. In "S", in the control means CON, Lna = 1. It is monitored whether Lmb = 1 or not, and if this condition is not met, the transporters 10a and 10b still have the passage detector Lna or Lmb.
, That is, it is considered that the vehicle is not approaching the stop 2n or 2m, the flow branches to the right in the flow of the figure, and is looped back to monitor the transition. To continue. Here, Lna = 1. Lm
If the condition of b = 1 is met, the transporters 10a, 10b
Is regarded as having passed the position of the passage detector Lna or Lmb and approaching the stop 2m, 2n, and the traverse platform 20m, 20n
Is determined to be incomplete.

Here, at the end of the platform traversing operation of "f" in FIG. 4, if the operation is normal, each platform detector should detect this as shown in "f" in FIG. That is, if Pna = 1, the traversing platform 20n of the stop 2n is correctly positioned at the center on the A-line side and the transporter 10a can arrive, and if Pmb = 1, the stop 2m Is located in the center of the line B and is in a state where the carriage 10b can be reached. Therefore, if both of these conditions are satisfied at the same time, the arrival of the carriages 10a and 10b can be safely entered. Because it is done. If the traversing operation is incomplete, for example, if the vehicle stops unexpectedly in the middle of traversing, etc., there is a possibility that an accident will occur if the carry-in enters, and the control means CON outputs the cable drive command signal sdc. Command the stop of the rope driving device 8 and the towing line 7 or the carrying device 10a,
The operation of 10b is stopped to ensure safety.

On the other hand, in FIG.
If the condition of Pmb = 1 is satisfied, the flow of "h" in FIG. 5 proceeds downward, the operation of the transporters 10a and 10b is continued, and the transporter 10a arrives at the traversing platform 20n of the stop 2n. The carrier 10b arrives and stops at the traversing platform 20m at the stop 2m.

When the transporters 10a and 10b arrive, the transporter detector Cna detects the "location" of the transporter 10a at the stop 2n and receives the transporter detector C, as shown in FIG.
The state of na is switched from 0 to 1 and at the stop 2 m, the carrier detector Cmb detects the “presence” of the carrier 10 b and the state of the carrier detector Cmb is also switched from 0 to 1 in this way. The operation ends.

Here, in preparation for the next reverse stroke operation of the transporters 10a and 10b, the passage detectors Lma and Lma as shown by "U" in FIG.
mb and Lna, Lnb are zeroed, that is, Lma
State from 1 to 0, Lmb state from 1 to 0, Ln
The state of a is changed from 1 to 0, and the state of Lnb is changed from 1 to 0.
Is switched over. Therefore, the state of each detector at the time when the transporters 10a and 10b have arrived and the operation of one stroke has been completed is, as shown in "sa" in FIG. 5, for the platform detector, Pma = 0, Pmb = 1, and Pna = 1,
Pnb = 0, and Cma = 0,
Cmb = 1, Cna = 1, Cnb = 0, and
For the passage detector, Lma = 0, Lmb = 0, Lna
= 0, Lnb = 0, which is the initial condition for the next reverse operation.

In this way, in the case of the next reverse operation, the functions and operations are performed in the same manner as in the case of the forward operation, and the safe operation is ensured.

[Effects of the invention] In the articulated cableway, etc., corresponding to the carriages that operate both round trip lines, the landing and platform for each carriage are fixed in parallel at the stops at both ends, Such conventional equipment is generally not economical due to its large scale, and it may be difficult to install the equipment, particularly in places with steep terrain. In such places, the stop is used as a platform for passengers getting on and off,
It is configured to be able to move traverse two positions between the reciprocating lines, and when the carrier arrives on one side of the reciprocating line, the platform is positioned on one side of the traversing path and the arrival of the carrier is received here and treated as a customer. It is preferred to use a traversing platform device which is moved to the other end of the traversing path and then receives the carriage on the other side after it has left the cableway.

However, since such a traversing platform device is used for both reciprocating carriages, it is particularly necessary from the viewpoint of safety that the platform switching operation is properly performed when the carriages are received. If the switching operation is not proper, there is a danger that the arrival carrier may collide with the platform, or the carrier may enter and arrive when the platform is not prepared and passengers cannot get on and off.

In the apparatus of the present invention, a platform detector for detecting the position of the traversing platform and outputting a platform signal, a carrier detector for detecting the presence / absence of a carrier at a stop and outputting a carrier signal, A passage detector that detects passage of the carrier and outputs a passage signal, and inputs signals output from these to the control means,
The control means issues an operation command for the traversing drive means and the cord drive device based on these.

[0038] This allows the traversing platform to perform the traverse switching operation only after the carriage leaves the stop and becomes absent, and is separated and separated. If the switching is not completed correctly, the operation of the carriage is stopped. To prevent entry.

As a result, the safety of the operation of the cableway equipment using the traversing platform is ensured.
