BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an introduction portion of a guide rail for guiding a guide roller of a handgrip at a stop of an automatic circulation type cableway.

[0002]

2. Description of the Related Art In an automatic circulation type cableway, a gripping machine is detachably gripped by a rope which is wound between pulleys pivoted at stops at both ends and circulates around the pulley. This is a facility that transports the suspended carriage by moving it along with the movement of the rope. In this automatic retrieving cableway, a single-track or double-track single-track automatic recirculating cableway that uses only one or more pulling ropes that also has the effect of supporting and towing the transporter, and towing the rope and the transporter that supports the transporter. A double track or three track automatic circulation type cableway using one or a plurality of towing lines is in practical use. Here, a conventional technique will be described for the case of a single-track automatic circulation type cableway which is most frequently used.

FIG. 9 shows a state of a carrier 310 in a cableway. The carriage 310 hangs the passenger car 312 from the cable hunting machine 320 via the suspension machine 311,
Handgrip part 322 extending from main body part 321 of handgrip 320
Is gripping the cable 303. The main body 321 is provided with a rod-shaped guide wheel shaft 325, and a guide wheel 324 is pivotally mounted on an end of the guide wheel shaft 325. Further, running wheels 323 and 323 are pivotally attached to the main body 321.

[0004] In the cableway 310, the cable 303 is being gripped by the gripper 320 in the cableway line as described above.
Reference numeral 20 is supported only by the rope 303 and is suspended. Therefore, the traveling wheels 323, 323 and the guide wheels 3
24 is not rolling and is in a free state. Therefore, when the transporter 310 is operating on the cableway, the position of the center of gravity changes due to the load state of the empty or loaded passenger car 312,
Due to fluctuations in the side wind pressure on the passenger car 312, etc.,
10 is an arrow 314a or 31 centered on the cable 303
4b, the guide wheel 324 of the handgrip 320 is vertically displaced in the direction of the arrow 315a or 315a around the rope 303.

FIG. 10 shows a case where the transporter 310 enters the stop. The towing machine 32 entered the stop
At 0, the vicinity of the handgrip portion 322 is introduced together with the rope 303 onto the rope guiding wheel 313, and the guide wheel 324 is introduced into the guide rail 330 having a groove shape in a front view and starts rolling. Thereafter, the traveling wheels 323 and 323 are introduced into the groove-shaped main track 304 and start rolling, and the rolling of the traveling wheels 323 and 323 and the rolling of the guide wheel 324 cooperate to grip. The attitude of the machine 320 is determined. Thereafter, the pressing guide wheel 326 pivotally attached to the main body portion 321 is further rolled while being pressed by a pressing guide rail (not shown) provided corresponding thereto, and the lifting of the towing machine 320 is performed. Has been prevented.
In addition, a gripping release wheel 328 pivotally attached to an end of a lever 327 provided on the main body 321 is pressed to release the rope 303 from the gripping portion 322. The pressing guide wheel 326 and the gripping and releasing wheel 328 are not directly related to the technology of the present invention, and therefore are abbreviated here.
Such a spring-type gripping machine 320 is disclosed in, for example, Japanese Patent Publication No. Hei 4-25911, "A main spring failure detecting device of a cableway gripping machine", and Japanese Utility Model Publication No. 3-51, proposed by the present applicant.
It is already known as described in, for example, Japanese Patent Publication No. 254, “Opening structure of a rope rig”.

As shown in FIG. 9, the guide wheel 324 is driven by the rolling swing of the carrier 310 in the cableway.
Is displaced in almost up and down directions.
When the vehicle enters the stop, the guide wheel 324 is introduced into the guide rail 330 as shown in FIG.
A zero posture correction is performed. In order to smoothly perform the introduction operation, a distal end portion 332 into which the towing machine 320 enters the guide rail 330 is conventionally formed into a horn-shaped or flared opening.

[0007]

FIG. 11 shows a state in the vicinity of a tip portion 332 of a conventional guide rail 330, and an arrow 329 indicates the approach direction of the handgrip 320.
The guide rail 330 is open in a horn shape or a flared shape.

[0008] When the guide wheel 324 of the rope pulling machine 320 enters with a bias toward the upper side, for example, at the position 324u of the guide wheel, it gradually converges to the center while rolling while contacting the upper guide surface 334u. The posture of the machine 320 is corrected. Similarly, when the guide wheel 324 of the towing machine 320 enters in a downwardly biased manner as in the position 324d of the guiding wheel, it gradually converges to the center while rolling while contacting the lower guide surface 334d. Posture is corrected. However, the guide wheels 324 are thus not
Is introduced into the upper or lower guide surface 334u or 334d of the vehicle, and when a collision occurs, it is accompanied by an impact, which is transmitted to the passenger car and impairs the ride comfort. There was a need for improvement.

The present invention has been made in order to improve the situation described above. Even when a guide wheel enters a guide rail with a displacement up and down, there is little impact and a cableway guide which does not impair ride comfort. The purpose is to provide a movable structure of the rail.

[0010]

According to this object, the present invention provides:
A guide installed at a stop of a circulation type cableway for transporting a rope by hanging a carriage with a rope pulling machine and attached to the rope pulling machine.
In the guide rail for guiding the wheels to correct the posture of the rope handling machine, the vicinity of the distal end of the guide rail is formed as a horn-shaped opening and elastically supported using elastic means, and the guide rail is Take the fixed portion near the base end
It is configured as a movable structure of a guide rail of a cableway which is attached and guides so as to allow vertical sliding displacement near the introduction end using a sliding guide mechanism.

[0011]

The movable guide rail in the movable structure of the guideway of the cableway according to the present invention is provided near the arrival point or the departure point of the carriage at the stop of the automatic circulation type cableway. The end of the movable guide rail where the gripping machine is introduced or retracted is formed to have a horn-shaped opening, is elastically supported by using an elastic means such as a spring, and has a sliding guide mechanism. It is guided and supported to allow vertical displacement near the part. .

[0012] In the cable carrier, the towing machine causes rolling swing and side-to-side swing due to the load conditions and the influence of the wind pressure load on the cableway line. In such a state, when the towing machine enters the stop, the towing cable is grasped. The guide wheels of the machine contact the upper or lower guide surfaces of the horn-shaped movable guide rails and roll, and are gradually guided to the center of the movable guide rails to converge, thereby correcting the attitude of the towing machine. At this time, the impact of the collision of the guide wheels is absorbed by the elastic support of the movable guide rail, and the riding comfort of the carrier is improved. In addition, since the sliding guide mechanism guides the top and bottom sliding of the movable guide rail tip, the movable guide rail is suppressed from lateral runout, and the guide wheels are prevented from derailing.
