DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cableway device in which a load is supported by a track installed in the air and a carrier is towed by a tow line, and in particular,
The present invention relates to a device capable of automatically stopping and starting a carrier at a station and maintaining a state of gripping a towed line even when an impact is applied to the carrier during movement.

(Prior Art) Conventionally, in mountainous areas and the like, luggage has been carried by using a cableway device, and recently, the cableway technology has been widely used in ski lifts and the like, and steep slopes have been used. It is designed to safely and efficiently perform the transport operation on various slopes. Among the above-mentioned general cableway devices, two types are known: a device that uses one cable wire and a compound cable device that uses two cable wires. In the case of a device for carrying relatively light loads, a single-line device is used as these cableway devices, and when carrying a large amount of loads or when a load carried by one carrier is large. In many cases, a multi-line type device that uses two cables, a track and a tow line, is used.

In the double-track type cableway device, the rail is arranged at a fixed position, the traveling sheave of the carrier is guided, and the carrier is moved using the tow line arranged in parallel with the rail, The hauling device is locked to the towed line and the hauling device is automatically released so that the cargo can be easily handled at the station.

And in the cableway device,
Provide a guide rail for releasing the pendulum at the station,
It is known that the sheave provided on the upper portion of the pendulum is used to release the towed rope when the sheave is mounted on the guide rail. In addition to the above-mentioned conventional example, as means for automatically releasing the tow line, for example
There is an example as shown in Japanese Patent No. 8253. The automatic releasing means for a pendulum shown in this conventional example is provided with a lever that engages with a guide rail at an end thereof, and by swinging the lever, a pendulum is provided by using a cam and a spring. It is possible to automatically grasp and release the towed rope.

(Problems to be Solved by the Invention) However, in the conventional device as described above,
If any impact or the like is applied to the lanyard while the carrier is moving, the sheave, arm, etc. will oscillate, and the rocking member will not be able to grip the tow line, causing the carrier to run out of control. There may be problems such as The problem that the above-mentioned impact is applied to the lanyard also occurs, for example, when the carrier oscillates due to the wind, but especially when passing the supporting portion of the railroad track by the tower, Therefore, a large impact is likely to occur. In addition, although various safety devices are provided to this carrier for problems such as runaway, especially in the case of a device with a large load that the carrier bears, even if the safety device operates, Subsequent recovery work requires a lot of trouble and time.

However, since the conventional cableway device is mainly intended to carry luggage such as earth and sand or ore, a relatively simple gripping mechanism is often used. On the other hand, in the case of a lift device or the like for passengers, a very complicated safety device is often provided, and applying such a complicated mechanism to a device for luggage is There are many problems in the construction cost of the device and maintenance.
