Abstract

(57) [Abstract] [Purpose] [Structure] When a carrier of an automatic circulation type cableway operates on a cableway line, it may oscillate to the left or right due to the influence of load conditions and wind pressure. Sometimes, the guide wheel of a gripping machine is introduced into a guide rail that opens like a horn to correct the posture to a normal posture. However, at the time of this introduction, it was a cause of giving a shock to the carrier and impairing the riding comfort. In the structure of this device, the vicinity of the tip end of the guide rail is movably suspended and supported by elastic means, and is guided so as to be vertically slidable by using a sliding guide mechanism. Even if the guide wheel enters a vertically biased position, the impact is mitigated and the ride comfort of the carrier is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an introduction portion of a guide rail that guides a guide roller of a gripping machine at a stop of an automatic circulation type cableway.

[0002]

[Prior art]

 The automatic circulation type cableway is wrapped between pulleys pivotally installed at the stops at both ends, and the circulating rope is used to detachably grip the gripper, and the carrier suspended from the gripper is searched. It is a facility that operates and transports along with the movement of articles. This automatic circulating cableway is a single-track or double-track single-line automatic circulating cableway that uses only one or a plurality of towlines that also support and tow a carrier, and a towline and carrier to support the carrier. A double-line or three-line automatic circulation type cableway using a single or multiple tug ropes is used in practice. Here, conventional techniques will be described for the case of the most frequently used single-track automatic circulation cableway.

FIG. 9 shows a state of the carrier 310 in the cableway line. The carrier 310 suspends a passenger car 312 to a gripping machine 320 via a suspending machine 311, and grips a cord 303 with a grip part 322 extending from a main body 321 of the gripping machine 320. . The body portion 321 is provided with a rod-shaped guide wheel shaft 325, and a guide wheel 324 is pivotally attached to an end of the guide wheel shaft 325. Further, traveling wheels 323 and 323 are pivotally attached to the main body 321.

The transporter 310 thus grips the cord 303 with the gripper 320 in the cableway line, and the gripper 320 is supported only by the cord 303 and is suspended. Therefore, the traveling wheels 323, 323 and the guide wheels 324 are in a free state without rolling. Therefore, while the carrier 310 is operating on the cableway line, the carrier 310 moves around the line 303 due to the change of the center of gravity position due to the load state of the passenger car 312 due to the load condition of the empty vehicle or the loaded vehicle, the fluctuation of the side wind pressure to the passenger car 312, and the like. Rolling swing is possible in the direction of 314a or 314b, and accordingly, the guide wheel 324 of the gripping machine 320 is also vertically displaced in the direction of arrow 315a or 315a about the rope 303.

FIG. 10 shows a case where the carrier 310 has entered the stop. In the gripping machine 320 that has entered the stop, the vicinity of the grip 322 is introduced on the rope guide wheel 313 together with the rope 303, and the guide wheel 324 is introduced inside the guide rail 330 that is a groove type in a front view. It will be started rolling. After that, the traveling wheels 323, 323 are introduced into the groove-shaped main rail 304 to start rolling, and the rolling of the traveling wheels 323, 323 and the rolling of the guide wheel 324 allow the traveling wheels 323, 323 to grip. The attitude of the rope 320 is determined. After that, the pressing guide wheel 326 pivotally attached to the main body 321 rolls while being pressed by a pressing guide rail (not shown) provided correspondingly, and the gripping machine 320 It prevents the rise of. In addition, the grip-and-release wheel 328 pivotally attached to the end of the lever 327 provided on the main body 321 is pressed to release the cord 303 from the grip-and-attach portion 322. The pressing guide wheels 326 and the grip-and-release wheels 328 are not directly related to the technology of the present invention, and thus are omitted here, but such a spring-type gripping machine 320 is, for example, the present application. It is already known as described in Japanese Examined Patent Publication No. 4-25911 “Main spring failure detection device for cableway gripping machine” and Japanese Utility Model Publication No. 3-51254 “Opening structure of gripping machine” proposed by a person. ing.

As shown in FIG. 9, the guide wheel 324 is displaced in the substantially vertical direction by the rolling swing of the carrier 310 in the cableway line, but next, the gripping machine 320 enters the stop. When doing so, as shown in FIG. 10, the guide wheels 324 are introduced into the guide rails 330 to correct the posture of the gripping machine 320. In order to smoothly perform this introducing operation, it has been conventionally performed that the tip end portion 332 into which the gripping machine 320 enters the guide rail 330 has a horn-shaped or divergently-opened shape.

[0007]

FIG. 11 shows a state near the tip portion 332 of a conventional guide rail 330, in which an arrow 329 indicates the approaching direction of the gripping machine 320, and the guide rail 330 indicates a wheel. It opens in the shape of a cone or a divergent shape.

When the guide wheel 324 of the gripping machine 320 enters with a bias toward the upper side, for example, at the position 324u of the guide wheel, it comes into contact with the upper guide surface 334u and rolls and then converges to the center next. The posture of the gripping machine 320 is corrected. Similarly, when the guide wheels 324 of the gripping machine 320 are biased downwardly at the guide wheel position 324d, they come into contact with the lower guide surface 334d and gradually converge to the center while rolling. 20 postures are corrected. However, the guide wheel 324 is thus introduced to the upper or lower guide surface 334u or 334d of the guide rail 330, and when a collision occurs, it is accompanied by an impact, which is transmitted to the passenger car and impairs the riding comfort. Since this tendency is expanded with the improvement of, the improvement has been required.

The present invention has been made to improve the above-mentioned circumstances. Even when the guide wheels enter the guide rail with vertical displacement, the impact is small and the riding comfort is not impaired. The purpose is to provide a movable structure of the guide rail.

[0010]

[Means for solving the problem]

 For this purpose, the present invention provides a guide rail for correcting the posture of the lanyard, which is provided at a stop of a circulation type cableway in which a carrier is suspended by a lanyard for transportation. A horn-like opening is formed in the vicinity of the tip of the guide rail, and elastic support is provided by using an elastic means, and a sliding guide mechanism is used to allow vertical sliding displacement near the introduction end. It is configured as a movable structure of the guide rail of the cableway that is guided as described above.

[0011]

[Action]

 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 carrier at the stop of the automatic circulation type cableway. The tip of the movable guide rail, into which the gripping machine is introduced or withdrawn, is formed so as to have a horn-like opening, and is elastically supported by an elastic means such as a spring, and equipped with a sliding guide mechanism. It is guided and supported to allow vertical displacement near the introduction end. .

[0012] In the cableway of the transporter, rolling swaying and side-to-side swaying occur in the cableway line under the influence of load conditions and wind pressure load. In such a state, the pontoon enters the stop. And the guide wheel of the gripping machine abuts on the guide surface above or below the horn-shaped movable guide rail and rolls, gradually being guided to the center of the movable guide rail and converging, and the posture of the gripping machine is corrected. . At this time, the elastic support of the movable guide rail absorbs the impact of the collision of the guide wheels to improve the riding comfort of the carrier. In addition, since the sliding guide mechanism guides the vertical slide of the tip of the movable guide rail, it prevents lateral movement of the movable guide rail and prevents derailment of the guide wheels.

That is, the protruding members 51, 51 are fixed and protruded to the side of the movable guide rail 31, and one hole 52 or 52 is formed in each of the protruding members 51, 51. Correspondingly, supporting members 53, 53 are also fixed to the frame 35 so as to project laterally, and one hole 54 or 54 is bored in each of these supporting members 53, 53. The holes 52, 52 and the holes 54, 54 are bored so as to be located on the same axis, and the rods 55 penetrate the holes 52, 52 and the holes 54, 54. Further, captive members 56, 56 formed by screwing nuts or the like are provided on the upper and lower portions of the rod 55. The diameters of the holes 52, 52 are set to be slightly larger than the outer diameter of the rod 55, and the rod 55 is in a state of being loosely inserted in the holes 52, 52.

Next, also in the frame 36 of the suspension portion Q, the movable guide rail 31 is vertically movably supported by the sliding guide mechanism 60 as shown in FIGS. 2 and 4. That is, projecting members 61, 61 are fixed and projected to the side of the movable guide rail 31, and one hole 62 or 62 is formed in each of the projecting members 61, 61.

Is occurring. In order to prevent this and correct the posture of the gripping rope 20, the guide wheel 24 of the gripping rope 20 is guided into the movable guide rail 31 of the guide rail 30 to roll, which is the same as in the above-mentioned prior art. The description is basically the same. In order to smoothly introduce the guide wheel 24 into the movable guide rail 31, a horn portion 33 is formed near the tip end portion 32.

In FIG. 6, the guide wheel position 24d shows a case where the guide wheel 24 enters the movable guide rail 31 in a state in which the guide wheel 24 is biased downward, and the guide wheel 24 comes into contact with the lower guide surface 34d to roll. Start. The movable guide rail 31 is “rigidly” supported in the suspension portion R, but since the introduction end portion 32 is a cantilever free end, the tension spring 42, 42 extends and balances, and flexibly deforms and follows the elasticity of the member of the cantilever portion of the guide rail 31 to absorb or absorb the shock. At this time, the slide guide mechanism 50 is allowed to move up and down, and similarly the slide guide mechanism 60 is allowed to move up and down. Of the guide wheel 24 is prevented, and the derailment of the guide wheel 24 from the movable guide rail 31 is prevented.

Further, as in the case of the first embodiment, the sliding guide mechanism 250 is provided to guide and support the vicinity of the tip end 232 of the movable guide rail 231 so as to be vertically slidable. Even with such a configuration, the operation and action are the same as those in the first embodiment.

[Effect of device]

 In a cableway line, a carrier of an automatic circulation type cableway causes rolling rocking and side-to-side shake to some extent due to load conditions of the carrier and fluctuations in wind pressure load, etc. It has been conventionally practiced to introduce the wheels into guide rails that open in the shape of horns to correct the posture of the carrier or the gripper. However, the impact of the guide wheel colliding with the guide rail was transmitted to the passenger car, causing an impact and impairing the riding comfort. In particular, this tendency is increasing as the driving speed of the cableway is improved. The movable structure of the guide rail of the cableway according to the present invention is such that the vicinity of the guide rail introduction end of the guide rail is movable like a cantilever, and is elastically supported by elastic means. The guide is supported so that it can slide in any direction and limit lateral roll.

With this configuration, when the gripping device of the carrier moves into the movable guide rail, the elastic means absorbs the shock, the shock transmitted to the carrier is reduced, and the riding comfort is improved. In addition, since harmful rolling of the movable guide rail is suppressed, it is possible to prevent the guide wheel from derailing from the movable guide rail.
