Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope pulling type transportation facility that pulls and carries a carrier on a laid track, and in particular, the rope pulling that can operate the carrier even if the shape of the track is concave. It relates to type transportation equipment.

  A cable-traction system such as a cable car or an incline is used to extend and stretch the cable along the rail on which the vehicle travels, and to connect the vehicle to the cable and connect the cable along the track. It is a transport facility that operates by pulling a vehicle by being driven to move. In this way, the rope pulling type transportation equipment has the rope extending in the line, and therefore the guide roller is arranged at predetermined intervals in the line so as to support and guide the rope. The article is supported.

  The structure of the vehicle in these rope pulling type transportation facilities is generally a structure in which the rope is connected to the center lower part of the vehicle, and the guide roller disposed in the track is suspended from the rope. In general, a configuration using a guide roller that supports the rope from below is used so as not to come into contact with the cable. In this configuration, the guide roller is disposed below the lower end portion of the vehicle so that the vehicle and the guide roller do not come into contact with each other when the vehicle passes. During operation of the vehicle, when the vehicle passes through the position of the guide roller, the strip leaves the guide roller upward, and after passing the vehicle, the strip descends and is supported by the guide roller again.

  The configuration of such a general line has a disadvantage in that the longitudinal cross-sectional shape of the line is limited because only the guide roller that supports the rope is arranged on the line below. In other words, in order for all the guide rollers arranged in the track to support the rope from below, the profile of the track is such that the start and end points of the track are connected by a straight line. Or it is necessary to set it as the longitudinal cross-sectional shape of the track | line used as the parabola which considered the droop by the dead weight of a rope.

  On the other hand, depending on the terrain that forms the track, there may be a depression or valley-shaped terrain in the track, and in this case, when the track is formed along the terrain, the rope rises upward in the concave part such as the depression As a result, the rope cannot be held at a predetermined height. Therefore, in order to obtain such a track shape, it is necessary to arrange a guide roller for pressing the rope from above in the concave shape portion to guide the rope along the rail or the rail. However, since the upper part of the rope is a space through which the vehicle passes, it is necessary to prevent the arrangement and structure of the guide roller from obstructing the passage of the vehicle. As a technique for solving this problem, a patent The technique described in Document 1 has been conventionally proposed.

  The prior art described in Patent Document 1 is generally configured as follows. A wheel (guide roller) that is disposed in the track and presses the rope is attached to a bar-like lever that extends in the vertical direction. The lower end portion of the lever is pivotally supported by a shaft, and the wheel can be rotated together with the lever in a direction perpendicular to the track. In addition, an operating roller is attached to the upper end of the lever. On the other hand, a rail having a U-shaped cross section that opens downward is provided in the lower part of the vehicle so as to extend in the front-rear direction of the vehicle, and this rail and the operating roller are engaged when the vehicle passes. The rail has a curved shape in which a central portion in the extending direction is curved to the side of the vehicle.

  With this configuration, when the vehicle first approaches the wheel, the rope is pushed down by the grasping device at the bottom of the vehicle to be lower than the maximum outer diameter of the wheel, and the wheel or lever does not interfere with the rope and the wheel. Is in a rotatable state. When the vehicle further approaches the wheel, the operating roller at the upper end of the lever is introduced into and engaged with the rail at the bottom of the vehicle, and the roller moves along the rail as the vehicle progresses. As described above, the shape of the rail is curved to the side near the center of the vehicle. Therefore, when the center of the vehicle passes the position of the roller, the roller moves to the side and the lever or The wheel is turned to the side, and the vehicle is allowed to pass by moving the wheel to a position where it does not contact the vehicle.

  In the prior art described in the above-mentioned Patent Document 1, since the guide roller (wheel) is rotated by a rail provided in the vehicle, the vehicle receives a lateral load when the device is operated. . Therefore, it is necessary to provide the vehicle with a guide roller or the like for restricting the movement in the left-right direction so that the vehicle does not shake due to the lateral load. Further, in the above-described conventional technology, the movable range of the induction roller (wheel) is limited due to its structure, and it cannot be used for a vehicle that does not have enough room in the lower space of the vehicle, or the induction roller. It is required that the components such as the (wheel) be configured compactly.

  This invention is made | formed in view of such a situation, Comprising: The objective is to support a rope | strand in a track | line, when the track | truck longitudinal cross-sectional shape of a cable traction type | formula transport equipment is formed in a concave shape. Therefore, there is no need to provide a special device, and it is an object of the present invention to provide a rope pulling type transportation facility that allows a vehicle to pass even in such a track shape.

  Further, the invention of claim 2 is the rope pulling transportation facility according to claim 1, wherein the carriage is provided with a passenger car suspended so as to be swingable in the front-rear direction with respect to the traveling direction. It is characterized by.

  According to the first aspect of the present invention, the rope is stretched on both sides of the rail, and the rope is connected to both sides of the carrier to be pulled. With this configuration, a space that avoids the incision guide roller can be easily formed on the side of the transporter. Therefore, it is only necessary to arrange the incision guide roller at a predetermined position, and it is not necessary to use a special device. Moreover, since the incline guide roller is provided on the outside of the rail, maintenance and inspection can be easily performed.

  According to the second aspect of the present invention, since the passenger car can be rotated in the front-rear direction even if the gradient of the track changes, the horizontal attitude of the passenger car can always be maintained.

The shape of the track shown in the figure passes from the foothill stop 18 through a steeply steep slope 20 to a gentle slope 21 near the middle, and then steeply again to the summit stop 19 again. The portion 22 is formed. In the steeply inclined portions 20 and 22 in the track, a receiving guide roller 16 that supports the rope 12 from below is arranged to support the drooping of the rope 12, while on the other hand, in the vicinity of the summit side of the gently inclined portion 21 In order to prevent the cord 12 from floating upward, the cord guidance roller 17 as an “upper cord guidance roller” and a “lower cord guidance roller” that supports the cord 12 by pressing it from above is disposed.

  FIG.1 and FIG.2 is the front view and side view of the carrier 10 which operate | move with a rope pulling type transport equipment. The transporter 10 includes a carriage 30, a suspension frame 38, a suspension machine 31, and a passenger car 32. Traveling wheels 33 and 34 and lifting prevention wheels 35 are rotatably provided at four lower and right and left lower end portions of the carriage 30 and roll along the rails 11. As shown in the figure, the rail 11 has a configuration in which a normal rail 37 used in a railway or the like is fixed to the upper portion of the H-shaped steel 36, and the rail 11 combined in this way is included in the track. Two rows are laid parallel to the horizontal direction. Of the traveling wheels 33, 34, the traveling wheels 33 in one of the left and right rows have a concave outer central portion that engages with the upper portion of the normal rail 37, and the left and right directions of the transporter 10. Restrict movement. Further, the lifting prevention wheel 35 is in contact with the upper part of the inner surface of the H-shaped steel 36 to prevent the transporter 10 from lifting upward.

  The carriage 30 is provided with a grinder 39 projecting from both sides in the vicinity of the center in the front-rear direction, and the carriage 30 and the rope 12 are connected by grasping the rope 12 by the grinder 39. The gripping machine 39 is a spring-type gripping machine 39 employed in, for example, a cableway or the like, and the gripping mechanism 39 is actuated or released by causing the deforming force of the spring built in the gripping machine 39 to act or be released. The machine 39 and the rope 12 can be connected or detached. The carriage 30 connected to the rope 12 with such a configuration moves while being pulled by both sides of the carriage 30 as the rope 12 moves.

  A suspension frame 38 is fixed to the upper portion of the carriage 30. The suspension frame 38 is formed by forming a gate-shaped member 38a in a gate shape in a side view on both the left and right sides, and connecting the lower portions of the gate-shaped member 38a with a connecting member 38b to form a frame shape. A space for accommodating the passenger car 32 is provided inside the suspension frame 38. The connecting member 38b at the front end portion and the rear end portion of the suspension frame 38 is formed with a connecting member 38c projecting downward at a position away from both side end portions, and is fixed to the upper portion of the carriage 30. Thus, the suspension frame 38 and the carriage 30 are connected. The lateral width of the suspension frame 38 is configured to be larger than the lateral width of the carriage 30.

At the top of the suspension frame 38, it has been pivotally supported to the traveling longitudinal direction pendant machine 31 between Ryomon shape member 38a, in the suspension device 31 via the vibration-absorbing material such as rubber The passenger car 32 is suspended. 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.

  Next, the aspect of the rope 12 extended between the foothill stop 18 and the summit stop 19 will be described with reference to FIG. A driving device 40 for driving the rope 12 is provided in the foothill stop 18. The drive device 40 includes drive pulleys 41, 41, a speed reducer 42, and an electric motor 43. The output shaft of the speed reducer 42 is arranged in the horizontal direction and extends to both sides. The drive pulleys 41 and 41 are connected to both ends of the output shaft so as to rotate in the vertical direction, and both the drive pulleys. The rope 12 is wound around the 41 and 41. An electric motor 43 is connected to the input shaft of the speed reducer 42, and the drive pulleys 41 and 41 are rotationally driven in the same direction via the speed reducer 42 by driving and controlling the motor 43. The drive device 40 is assembled on, for example, a single frame (not shown), and these are integrated so as to be movable back and forth in the line direction. By applying a certain force toward the wire, the tension of the rope 12 in the track is kept constant.

  At the summit stop 19, turntable pulleys 44, 44 are installed at fixed positions so as to rotate in the vertical direction, and each turnup pulley 44, 44 and the corresponding drive pulley 41, 41 of the foothill stop 18. Between these, the ropes 12 and 12 are stretched endlessly. The distance between the turn pulleys 44 and 44 and the distance between the drive pulleys 41 and 41 are slightly larger than the distance between the left and right ends of the two rails 11 and 11 in the track. The rails 11 and 11 are arranged in parallel to the sides. In addition, guide rollers 45 and 45 and guide rollers 46 and 46 are arranged on the line direction sides of the drive pulleys 41 and 41 and the folding pulleys 44 and 44, respectively, and thereby the lower rope 12 is moved upward. The vertical distance of the rope 12 is made closer in the track. In such arrangement of the rope 12, the transporter 10 is connected to and pulled by the left and right ropes 12, 12 extending upward.

  As described above, the transporter 10 is configured to be pulled by the two strips 12, and as a result, the traction force applied to the strip 12 is halved compared to the conventional configuration that is pulled by the single strip. Therefore, it is possible to employ the rope 12 having a small rope diameter. Along with this, the drive pulley 41 and the turntable pulley 44 can adopt a smaller diameter, and the receiving guide roller 16 and the indentation guide roller 17 in the track also use small ones. be able to.

  FIG. 5 is a front sectional view showing the structure of the track. Supports 51 and 51 are erected on the upper part of the concrete foundation 50 placed in the ground with a space in the left and right direction, and an arm 52 is extended in the left and right direction on the support 51 and 51. ing. In the vicinity of the upper center of the arm 52, the left and right rails 11, 11 are fixed at a predetermined interval. These concrete foundations 50 or arms 52 are appropriately provided in the track to support the rail 11. The left and right ends of the arm 52 are provided with receiving frames 53 and 53 extending upward. Incline guide rollers 17 are rotatably provided at two locations on the rail 11 side of the cable receiving frames 53 and 53, and the cable 12 is pressed and supported from above. The incline guide roller 17 is provided by arranging one or a plurality of the incline guide rollers 17 in a line in the line direction by the load received from the rope 12. Moreover, in the figure, although the incline guide roller 17 arrange | positioned at the upper part of the rope 12 is shown, when using the receiving guide roller 16 which supports the rope 12 from the downward direction, below the rope 12 The receiving guide roller 16 is disposed, and the pressing guide roller 17 and the receiving guide roller 16 may have the same structure.

  FIGS. 6 and 7 are a front view and a side view showing a state in which the transporter 10 passes through a position including the indentation guide roller 17. In FIG. 6, the right side of the center line shows a state in which the grinder 39 of the transporter 10 passes the position of the pressure guide roller 17, and this state is shown by a solid line in FIG. 7. In this state, the position where the grinder 39 grasps the rope 12 is a position slightly separated downward from the upper incision guide roller 17, and the carrier 10 approaches the position during operation. When it comes, the rope 12 is gradually pushed downward away from the cord guidance roller 17, and when the gripping device 39 passes, the cording device 39 does not touch the cord guidance roller 17 and moves to this position. pass. After this, the ridge 12 gradually rises as the carrier 10 moves away, and is again supported by contacting the traction guidance roller 17. As described above, the gripping device 39 and the indentation guide roller 17 do not come into contact with each other when the transporter 10 passes through, so that vibration associated with the passage does not occur, and riding comfort is not impaired.

  Next, the positional relationship between the suspension frame 38 of the transporter 10 and the incision guide roller 17 is as follows. The left side of the center line in FIG. 6 shows a state when the mountain side end portion of the suspension frame 38 passes through the incision guide roller 17, and this state is shown by a two-dot chain line in FIG. 7. As shown in FIG. 6, the shape of the suspension frame 38 in front view is such that the lower ends of the left and right side portal members 38a are located slightly above the indentation guide rollers 17, and the lower ends of these portal members 38a. The space is connected by a connecting member 38b having an inverted trapezoidal shape. Further, the left and right end portions of the carriage 30 connected to the lower side of the gate-shaped member 38 a are located away from the indentation guide roller 17 inward. With such a shape, a space through which the incline guide roller 17 can pass is formed below the portal member 38 a and on the side of the carriage 30, and the indentation guide roller 17 contacts the carriage 30 and the suspension frame 38. There is nothing to do. Such a configuration is also the same at the mountaintop side end of the suspension frame 38.

  As described above, the positional relationship between the crush guide roller 17 located above the rope 12 and the carrier 10 has been described. The positional relationship in the case of the receiving guidance roller 16 that supports the rope 12 from below is as follows. Become. The position where the grinder 39 of the transporter 10 grips the rope 12 is located slightly above the upper receiving guide roller 16, and when the transporter 10 approaches the position, the rope 12 is separated from the receiving guidance roller 16 and gradually lifted upward. When the gripping machine 39 passes, the gripping machine 39 passes through this position without contacting the receiving guidance roller 16. After that, the rope 12 is gradually lowered as the transporter 10 moves away, and is again supported by contacting the receiving guide roller 16. In this case, since the receiving guide roller 16 is positioned below the position of the pressure guiding roller 17, it is clear that the receiving guide roller 16 can pass without contacting the carriage 30 and the suspension frame 38.
