Description

  The present invention relates to a device for restraining a shake of a passenger vehicle stopped in a stop in a front-rear direction in a transportation facility that transports passengers using a suspended passenger vehicle.

  As a representative example of the transportation facility using the suspension type passenger car, there is a cableway facility for transporting the passenger vehicle by hanging it on a cable stretched in the air. In addition, the rail is elevated at a predetermined position in the air, the rope is stretched along the rail, and the traveling device or passenger vehicle is operated along the rail by pulling the traveling device with the passenger car suspended by the rope. A transportation facility is also known (for example, see Patent Document 1). Furthermore, it is also known as a transportation facility that has a track laid on the ground and a chassis that runs along this track. The chassis is equipped with a hanger arm to suspend a passenger car and pull the chassis with a cable. (For example, refer to Patent Document 2).

  A feature of the transportation facility using the above-described suspended passenger car is that the passenger car is configured to be swingable with respect to the traveling direction. In other words, with this configuration, even when the slope of the rail or the rope in which the passenger car moves changes, the passenger car is kept vertically suspended by its own weight. It is characterized by being kept horizontal. On the other hand, when the passenger car starts, stops, accelerates, or decelerates, the passenger car swings back and forth in the traveling direction.

  In addition, the cableway facility among the above-mentioned transportation facilities has a characteristic that the passenger vehicle swings in the lateral direction with respect to the traveling direction due to the configuration in which the passenger car is suspended from the rope. Because of this characteristic, in the cableway facilities, the platform of the stop is made wider than the width of the passenger car, and the passenger car that arrives at this position is sandwiched from both sides of the passenger car so as to buffer the lateral vibration of the passenger car. An apparatus made in this way has been proposed and put into practical use (see, for example, Patent Document 3).

  As described above, in the transportation facility using the suspension type passenger car, the passenger car is configured to be swingable back and forth in the traveling direction with respect to the rope or the rail, and thus has the following problems. In general, a suspension type passenger car is configured such that a plurality of passengers are on board. For example, a small one has a capacity of about four persons, and a large one has a capacity of hundreds of people. As described above, since a plurality of passengers board the passenger car, the floor surface of the passenger car is kept horizontal if the passengers on the passenger car are evenly distributed in the passenger car. However, if the passenger distribution is biased to either the front or rear of the passenger car, the floor surface of the passenger car also inclines in the front-rear direction corresponding to this offset load.

  When the passenger car stops at the stop in such a state, the floor of the passenger car is inclined with respect to the platform of the stop provided horizontally. There will be a step between the two. Such a step is not preferable because it induces passengers to trip, and it is difficult for a wheelchair user to pass.

A vibration absorbing material such as rubber is provided on the suspension machine 31. Passenger car 32 is suspended through. With this configuration, when the traveling inclination angle of the transporter 10 changes in the track, the suspension machine 31 or the passenger car 32 rotates with respect to the carriage 30 or the suspension frame 38, and the attitude of the passenger car 32 is always kept horizontal. It is.

  3, 4 and 5 are a front view, a plan view and a side view showing the relationship between the passenger car 32 and the platform 40 at the transporter stop position at the stop. On the side of the lower end of the passenger car 32, there is provided a passenger car step 32 a that protrudes laterally along the side surface of the passenger car 32. The upper surface of the passenger car step 32 a is substantially flush with the floor surface of the passenger car 32, and is formed to extend to a length longer than the door opening of the passenger car 32. On the stop side, a platform 40 is formed on the side of the carrier 10 at substantially the same height as the floor surface of the passenger car 32. The platform 40 is stopped at a position where the platform 40 is stopped. An opening 41 that opens in a concave shape is formed, and the opening 41 is provided with a movable step device 42.

  The movable step device 42 includes a main body frame 43 fixed to the stop, a movable frame 44 pivotally supported on the upper end portion of the main body frame 43, and an actuator 45 that rotationally drives the movable frame 44. It has. As shown in FIG. 5, the main body frame 43 has a shape in which the central part of the columnar members 43 a and 43 a that extend upward in parallel and a part near the lower part and the upper end part are connected by connecting members 43 b and 43 c in a side view. A floor plate 46 is provided at the upper end portion so as to close the opening 41 of the platform 40, and one end portion of the actuator 45 is pivotally supported via a bracket 47 at the central portion of the connecting member 43b. Further, shaft support portions 43d and 43d are formed in the upper end portions of both columnar members 43a and 43a in the direction toward the passenger car 32, and the movable frame 44 is pivotally supported here.

  The movable frame 44 has a substantially rectangular shape in plan view and can be rotated between an upright vertical state and a fallen horizontal state. When the movable frame 44 is in a horizontal state, the upper surface of the movable frame 44 has a passenger car step 32a and a passenger car step 32a. It becomes substantially flush with the upper surface of the floor board 46, and a passage surface is formed between the passenger car step 32 a and the floor board 46. The end of the actuator 45 is pivotally attached to the surface of the movable frame 44 opposite to the passage surface, and the movable frame 44 is rotated by the expansion / contraction operation of the actuator 45.

  At both ends of the movable frame 44 on the passenger car 32 side, pressing portions 48 are provided. FIG. 6 is a partial cross-sectional front view showing details of the pressing portion 48 in the horizontal state of the movable frame 44. The pressing portion 48 includes a substantially L-shaped bracket 49 that protrudes upward from the passage surface of the movable frame 44 in a horizontal state and has an upper end extending in the direction toward the passenger car 32, and the roller 50 is disposed at the tip portion of the bracket 49. The roller pin 51 is rotatably supported along the direction of movement of the passenger car 32. In this configuration, the roller 50 is located at a position protruding from the leading edge of the movable frame 44 and away from the passenger car 32, and the lower end of the roller 50 is the same as the height of the passage surface of the movable frame 44 or slightly more than the passage surface. High position.

  With such a configuration, the movable step device 42 operates as a shake restraining device for the passenger car 32 as described below. The movable step device 42 keeps the movable frame 44 in an upright state as indicated by a two-dot chain line in FIG. 3 when the transporter 10 is not located at the stop. When the transporter 10 arrives at the stop and stops at a fixed position, the actuator 45 of the movable step device 42 operates to move the movable frame 44 gently toward the passenger car 32, and accordingly, the pressing portion 48 of the movable frame 44. The rollers 50, 50 included in the above are lowered to the upper side of the passenger car step 32 a.

  In the transporter 10, when the load mounted on the passenger car 32 is biased in the front-rear direction, the passenger car 32 is inclined in the front-rear direction. For example, as shown by a two-dot chain line in FIG. Yes. When the transporter 10 is stopped in this state, the roller 50 positioned on the higher side of the passenger step 32a presses the upper surface of the passenger step 32a as the movable frame 44 rotates, and the roller 50 is lowered. Passenger car step 32a thru / or passenger car 32 rotates, and the attitude of passenger car 32 becomes level gradually. At this time, as the passenger car 32 rotates, the passenger car step 32a also moves in the front-rear direction relative to the roller 50. The passenger car step 32a can be easily moved in the front-rear direction while being pressed.

  Thereafter, when the movable frame 44 is stopped in a horizontal state, the rollers 50 and 50 restrict the vertical movement of the passenger vehicle step 32a in the vicinity of both front and rear ends of the passenger vehicle step 32a, and the horizontal state of the passenger vehicle 32 is maintained. Therefore, when passengers get on and off after this, even if a load shift occurs in the passenger car 32, the passenger car 32 is kept level, and the passenger can get on and off safely.

  Next, in the above-described movable step device 42, a different configuration of the pressing portion 48 provided in the movable frame 44 will be described with reference to FIG. In FIG. 7, a protrusion 52 is formed at the front end of the bracket 49 on the passenger car 32 side, and a slide plate 53 is fixed to the front end of the protrusion 52 and the upper surface of the passenger car step 32a. The slide plate 53 has a low friction coefficient. For example, a generally known material or product such as an oil-free bearing material formed by uniformly dispersing a solid lubricant such as graphite in a metal base material is used. Use it. According to this configuration, even when the inclined passenger car step 32a is pushed down as described above, the friction resistance between the slide plates 53 and 53 is low, so that the passenger car step 32a is easily pushed in the front-rear direction while being pressed. Can be moved to.

  Further, the slide plate 53 may be fixed through elastic means instead of the protruding portion 52. For example, as shown in FIG. 8, a rubber spring 54 may be attached to the front end of the bracket 49 on the passenger car 32 side so that the slide plate 53 is fixed to the lower end of the rubber spring 54. In this case, the lower end of the slide plate 53 provided at the tip of the rubber spring 54 may be set so as to be located slightly below the upper surface of the passenger car step 32a. With this configuration, when the passenger step 32a is depressed, the rubber spring 54 absorbs vibration and the like, and when the depression is completed, the passenger step 32a can be firmly pressed and fixed by the compression repulsive force of the rubber spring 54. As the elastic means, various springs, gas or liquid dampers, or the like may be used.

  In the above description, the structure in which the movable frame 44 performs the steadying operation and becomes a passage for the passengers is shown. However, the present invention is a method in which the passenger car swings back and forth, such as cableway equipment and monorail equipment. The present invention is applicable to facilities, and depending on the size and structure of the transporter, the passenger passage and the pressing unit that pushes down the passenger car step may be configured to operate independently.
