Further, during this time, passengers are handled near the getting off zone 26 and passengers are handled near the getting on zone 21. Next, the transporter 10 or the towing machine 11
Is accelerated to the speed synchronized with the speed of the rope 3 by the acceleration transfer device 9, and at around the point H, the towing machine 11 grips the rope 3 and starts moving in the direction of the arrow 5 b with the movement of the rope 3. .

In FIG. 1, only two transporters 10 are shown and others are omitted, but in practice, a plurality of transporters 10, 10... Are used, and at predetermined intervals or at predetermined intervals. It is operated one after another.

FIG. 2 shows details in the vicinity of the riding zone 21 in FIG. Rail 6 is in stop area 1
The carriage 10 is slowly moved along the rail 6 in the direction of the arrow 5b from the carriage position 10a to 10c through the carriage position 10b by the towing machine 11 which also functions as a traveling machine. .

The rectangular riding zone 21 is formed at the same level or slightly higher than the general floor in the area 1 of the stop, and passengers are guided in the direction of arrow 25 to enter the riding zone 21. Get on the transporters 10, 10,.
The fences 22 and 23 are provided to restrict passengers from entering the passage area of the transporter 10 from the boarding zone 21.

On the rail 6 near the riding zone 21, movable rails 31, 34 for detecting the load of the transporter are provided. As shown in FIG. 3, the rail 6 is separated into an end 6a and an end 6b in the vicinity of the riding zone 21, the vicinity of the end 6a is supported by a hanger 41a, and the vicinity of the end 6b is supported by a hanger 41b. . These hangers 41a,
41b are each suspended at a fixed position 42, for example, a ceiling beam of a building at a stop.

The movable rails 31 and 34 are interposed between the end 6a and the end 6b. That is, the support-side end 32 of the movable rail 31 is connected to the end 6a by the pin 3
7, and the tip side forms a floating end 33. A bearing-side end 35 of another movable rail 34 is pivotally connected to the end 6b by a pin 38, and the movable rail 31
The front end forms a floating end 36. Here, a hole 40 is drilled near the free end 36 of the movable rail 34, while a pin 39 provided near the free end 33 of the movable rail 31 is loosely inserted into the hole 40. Thus, the movable rails 31 are interconnected about the pin 38 so as to be pivotally displaceable within the play between the pin 39 and the hole 40.

On the other hand, another hanger 52 is suspended from a fixed position 42 in the vicinity of the loosely connected portion between the movable rails 31 and 34. An elastic member 50 and a shock absorber 51 are interposed between the hanger 52 and the lower surface near the floating end 33 of the movable rail 31. Although the elastic member 50 is shown using a spring in the drawing of this embodiment, other elastic members such as elastic rubber members that bend or displace almost in proportion to the load can also be used. is there. In addition, shock absorber 5
Numeral 1 is for suppressing excessive vertical floating displacement of the floating end 33. In addition, the free end 3 of the movable rail 31
A striker or operating member 53 is protruded near 3 and the hanger 52 is provided with an overload detector 54 using a detector such as a limit switch.

The operation and operation of the apparatus according to the present embodiment in such a configuration and arrangement will be described below.

First, in FIG. 2, the transporters 10, 10... Are transported slowly along the rail 6, and are transported at positions 10a, 10a of the transporters.
Progressing sequentially like 10b and 10c, the doors 12 and 12 are opened near the position 10a of the transporter. The passenger is guided in the direction of arrow 25 and moves from the vicinity of the position 10a of the carrier to the position 1 of the carrier.
While approaching the vicinity of 0c, the driver sequentially gets on the moving carrier 10, and the doors 12, 12 are closed near the location 10c of the carrier. Door 1
The doors 2 and 12 are automatically opened and closed in accordance with the progress of the transporter 10 in the same manner as conventionally performed. The carrying device 10 on which the passengers have finished riding is accelerated by the acceleration transfer device 9 and departs in the direction of the cableway 4.

In the vicinity of the position where the passenger has almost completed the ride on the carrier 10, that is, in the vicinity of the position 10c of the carrier in FIG.
Movable rails 31 and 34 are provided, and these movable rails 31 and 34 are loosely connected to each other by pins 39.
The carry 10 is rolled in the direction of the arrow 5b along the rail 6 by the rigging machine 11 using a chain-type transfer device or the like, as is conventionally performed, although not particularly shown, from the end 6a. It enters on the movable rail 31 and rolls.

When the carrier 10 enters the area of the movable rail 31, the movable member 31 has an elastic member 5 near the free end 33.
0, the elastic member 50 bends in proportion to, or almost in proportion to, the magnitude of the load on the transporter 10,
As shown schematically in FIG. 4, the movable rail 31 pivots about the pin 37 in the direction of the arrow 55 relatively slightly.
With this rotation, the floating end 33 and the striker or operating member 53 projecting therefrom are displaced downward. When the load of the transporter 10 is large, the descending displacement is also large, and the operating member 53 contacts the overload detector 54 to activate it. In this manner, the contact of the overload detector 54 is opened or closed, and an overload signal sl is output. Based on this, a notification to the remote monitoring center, an alarm by sound, light, or the like is issued, or the carrier 10 Safety measures, such as preventing departure, are taken.

On the other hand, in the vicinity of the floating end 33 of the movable rail 31, the floating end 36 of the opposing movable rail 34 is loosely connected via a pin 39, so that it is movable as shown in FIG. The rail 34 rotates slightly around the pin 38 in the direction of the arrow 56.

Although the transporter 10 in which no overload is detected is allowed to pass as it is, the floating end 33 and the floating end 36 have substantially the same level without any step due to the loose insertion and connection of the pins 39. Since it is at the height level,
The rope rig 11 passes through this transition part almost without step, travels in the direction of the arrow 5b through the end 6b of the rail 6, and departs from the stop area 1 via the acceleration transfer device 9.

(Second Embodiment) The present embodiment relates to the related invention of claim 2, and here, in addition to the equivalent of the device of the first embodiment, further detects the load of the transporter. A transport detector 160 is added to specify a position to be performed.

FIG. 5 shows the structure and arrangement of the present embodiment. The symbols used in the above embodiment with the 100th place added are the same as those in the above embodiment. Functions are equal. Here, in addition to the above case, a carrier detector 160 is provided at a position on the passage of the handholding machine 111 where the load of the carrier 110 is to be detected. A contact type or non-contact type sensor such as a limit switch can be used as the carry detector 160. When the carry 110 or the towing machine 111 passes this position, this is detected and the carry signal sc Is output.

FIG. 6 is a block diagram showing a system of transmission and processing of each signal. The overload signal sl output from the overload detector 154 in the figure and the carry signal sc output from the carry detector 160 are respectively input to the control device 161. In the control device 161, the carrier signal sc
And only when the overload signal sl is input at the same time,
The control signal sj is output, and the switch 162 is operated based on the control signal sj to take necessary safety measures.

The operation and operation of the above-described arrangement and signal transmission are as follows.

The manner of movement of the transporter 10 is the same as that of the above embodiment. As shown in FIG. 5, when the carriage 110 enters the movable rail 131, the elastic member 150
Deflection occurs in response to a load or weight of 10. In this way, when the transporter 110 enters the position of the transporter detector 160, the transporter detector 160 detects this and outputs a transporter signal sc
To the control device 161. On the other hand, since the movable rail 131 deflects in the elastic member 150 in response to the load of the transporter 110, the movable rail 131 causes a rotational displacement around the pin 137, and the movable rail 131 operates when the displacement amount is larger than a certain value. The use member 153 activates the overload detector 154, and thus the overload detector 154 outputs the overload signal sl.

FIG. 7 is a flowchart showing the processing in the control device 161. In the processing flow in the figure, the carrier detector 160 outputs the carrier signal sc and sends it to the control device 161 only when the carrier 110 passes through the position,
If the transporter 110 does not pass, detection is continuously waiting. The overload detector 154 sends an overload signal sl to the control device 161 only when an overload state is detected, and continues to wait for detection when the overload condition is not reached.

In the control device 161, when these carry-over signals sc and overload signals sl are simultaneously inputted,
That is, when the carry-in signal sc and the overload signal sl are under the AND condition, the control signal sj is output. According to the output of the control signal sj, the switch 162 is operated as shown in FIG. 6 to perform necessary safety measures, for example, notification to a remote monitoring center, alarm by sound or color light, or prevention of departure of the carrier 110. Safety measures can be implemented.

When only the carry signal sc is input and the overload signal sl is not input, the load of the carry is considered to be within the allowable range, and only the overload signal sl is input and the carry signal sc is input. When not performed, it is considered that the transporter 110 is not located at a suitable position for weighing, the control signal sj is not output in any case, and the processing flow in the flowchart is turned upward and traced, The state of waiting for detection is continued.

In this embodiment, as compared with the first embodiment, the position on the movable rail at which the transporter should be weighed can be specified at a fixed location. In addition, it is possible to reduce a detection error or to prevent a malfunction due to a disturbance when the transporter is not located.

[0038]

According to the present invention, the safety device for detecting the load of the carriage of the automatic circulation type cableway detects the load or the weight of the carriage near the boarding zone of the automatic circulation type cableway when the passenger is completely or almost completed. If the permissible limit is exceeded, the security officer will be notified and take safety measures.

In the riding zone of the cableway, conventionally, an attendant generally attends, and, under the supervision and guidance, counts and confirms the number of boarding passengers and allows them to board. On the other hand, cableway facilities are not only intended to be used as conventional transportation means for mountainous areas, but also for use between small and medium-sized transport aircraft for general traffic. In the field, automation, remote monitoring operation, and the like, which are performed in a new transportation system, are demanded.

In the current regulations for cableway driving, the limit for carrying on and off the vehicle is set by the capacity.
Although the detection by weight is an indirect method like the present apparatus, the present apparatus can be effectively utilized as an auxiliary means or a backup means for passenger safety in the case of automation, remote monitoring operation and the like.
