Description

  The present invention relates to a carriage of a rope pulling type carrier that pulls and carries a carrier on a laid track.

  Cable-drawing transportation equipment that pulls passenger cars and carts (hereinafter collectively referred to as “carryers”) by means of ropes is a cable car that transports personnel as passenger equipment, and transportation of goods as industrial equipment. It is known as an ink line or the like for performing the above. As a general configuration of the rope pulling type transportation equipment, a carrier is movably installed on a laid rail, and the carrier connected to the carrier is wound around and driven by a winch or a pulley so that the carrier is It is configured to move along the rail.

  As described above, the carrier in the rope pulling type transportation facility is moved by being pulled by the rope, so that the carrier itself is not provided with a drive device, and therefore the traveling sound is quiet and the structure of the rail is also low. Since it is relatively simple, there is an advantage that it is low cost, and it is excellent in that the natural environment is not impaired much. Moreover, since the movement of the transporter is not due to the frictional resistance between the wheels and the rails, the transporter can travel even when the traveling slope is steep, and is frequently used as a transportation facility on sloping ground.

  When the rope pulling type transportation equipment is used on sloping terrain, a pulley for driving the rope is installed at the stop on the summit side, the rope is wound around this pulley, and a carrier is connected to both ends of the rope. Alternatively, a system is often employed in which a carrier is connected to one end and a counterweight is connected to the other end to operate in a so-called vine manner (see, for example, Patent Document 1). In addition, there is a system that operates by winding or unwinding a rope with a winch, for example, instead of such a sliding system (see, for example, Patent Document 2).

  On the other hand, when used on flat terrain, the following configuration is generally adopted because it is necessary to apply a certain tension to the rope. First, the rope is stretched in an endless loop along the track, and the rope is wound around a plurality of pulleys provided at a stop or the like. The pulley at any one of these pulleys is configured to be movable in a state where the rope is wound, and a tension is applied to the pulley by applying a certain force to the pulley. ing. Further, a power source such as an electric motor is connected to another pulley, and the pulley is driven to rotate by this to move the rope (see, for example, Patent Document 3). The carrier is connected to a predetermined position of the looped rope and reciprocates between the stops.

  As described in each of the above-mentioned patent documents, the rope connected to the carrier is generally one, but depending on the load conditions and other safety conditions, There are cases where a method of towing a cart is adopted. In this case, it is difficult to make the lengths of the two cords exactly the same, and in order to solve this problem, the carrying device is equipped with an equalizer for adjusting the cord length, and the cords are connected to the two cords. It has been conventionally proposed to balance the tension of the rope of the book (see, for example, Patent Document 4). In addition, a configuration has also been proposed in which a pulley is rotatably provided at the bottom of the transporter, and a single rope is wound around the pulley and substantially pulled by two ropes (for example, Patent Document 5). reference).

JP 2002-87247 A JP 2002-347609 A Japanese Utility Model Publication No. 5-89140 Japanese Patent Laid-Open No. 8-133068 JP 2007-190962 A

  In such a rope pulling type transport equipment carrier, as shown in the above-mentioned document, it is required that unnecessary behavior of the towing rope does not reach the carrier as much as possible. For example, when towing a transporter with two ropes, if the diameter of each pulley that wraps and drives the two ropes is slightly different, both ropes will move with the progress of the driving stroke. Therefore, it is desirable to provide a device for balancing the difference. In addition, when the position of the rope is displaced in the left-right direction with respect to the traveling direction, a lateral force acts on the transporter. It is desirable to buffer the direction force.

  The present invention has been made in view of such circumstances, and in a rope pulling type transportation facility that pulls a carrier with two ropes, the rope that can cope with the behavior of the above ropes. The object is to provide a cart of a towed carrier.

  In order to solve the above-mentioned problem, the invention of claim 1 is a carriage of the carrier of a rope pulling type transportation facility that operates by pulling a carrier with two ropes on a laid rail, The carriage has a main body frame provided with traveling wheels that roll on the rail, a traction frame having a parallel link structure that is slidably supported by the main body frame, and a gripping machine supported at both ends of the traction frame, And a laminated rubber interposed between the main body frame and the traction frame.

  According to a second aspect of the present invention, in the carriage according to the first aspect, beams are provided at both ends of the tow frame, and the gripping machine is supported at both ends of the beam.

  According to the first aspect of the present invention, the gripping machine is provided at both ends of the traction frame of the parallel link structure, and the gripping machine is configured to be towed by gripping the rope. When a difference occurs in the amount of movement of the rope, this difference can be absorbed by the deformation of the traction frame. In addition, the main body frame is pulled by the traction frame via the laminated rubber, and when a lateral force acts on the traction frame, the laminated rubber deforms in the lateral direction, thereby causing a lateral force. Can act on the body frame.

  According to the second aspect of the present invention, beams are provided at both ends of the traction frame, and a rope is supported at both ends of the beam, so that one rope is gripped by two ropes. Therefore, it is possible to bear a larger load, and even if a fault occurs in one grinder, the other one functions so that the carrier is not separated from the rope.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a longitudinal section of the track showing an example of the track of the rope pulling type transportation facility. As shown in the figure, the track of the rope-drawing transportation facility is formed by connecting a foothill stop 18 at a low altitude and a summit stop 19 at a high altitude. In addition, the rail 11 is laid, and the rope 12 is also extended along the rail 11, and the carrier 10 is pulled on the rail 11 by the rope 12 and travels. In the track, a receiving guide roller 16 and a pressing guide roller 17 are arranged to support the rope 12 in order to maintain the position of the rope 12.

  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 are rotatably provided at four lower and left and right lower end portions of the carriage 30, and these wheels roll along the rail 11 and the transporter 10 travels. 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 central portion on the outer periphery, and the concave portion engages with the upper portion of the normal rail 37, and the left and right directions of the transporter 10. Regulate the movement of

  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.

  On the upper part of the suspension frame 38, a suspension machine 31 is pivotally supported between both gate-shaped members 38a so as to be swingable in the forward and backward direction. The suspension machine 31 is provided with a passenger vehicle through a vibration absorbing material such as rubber. 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.

  4 and 5 are a plan view and a side view of the carriage 30, respectively, FIG. 6 is a view taken along the line AA in FIG. 4, and FIG. 7 is a perspective view. Incidentally, the illustrated carriage 30 travels on a sloping track as shown in FIGS. 1 to 3, and actually travels with an inclination so that the direction of the arrow B shown in FIGS. 1 and 2 becomes higher. What is to be done is shown horizontally in the figure for convenience.

  The cart 30 has a prismatic main body frame 40 that is elongated in the traveling direction, and a rectangular frame-shaped running wheel frame 41 is formed on both ends of the main body frame 40 so as to protrude from both sides. Traveling wheels 33 and 34 are rotatably supported at both ends of the frame 41. A traction frame 43 is provided near the center of the main body frame 40. The traction frame 43 is composed of a horizontal frame 44 and a vertical frame 45 which are parallel to each other, and has a link structure in which respective end portions are connected to each other by a pin 46 so as to be horizontally rotatable. The traction frame 43 is placed on the upper surface of the main body frame 40 via a slide plate 47 for reducing the frictional force, and is connected to the main body frame 40 at four locking portions 48 as described below. It has been stopped. For the slide plate 47, a generally known material or product such as an oil-free bearing formed by uniformly dispersing a solid lubricant such as graphite in a metal base material may be used.

  As shown in FIG. 6, a through hole 49 is formed in the locking portion 48 of the horizontal frame 44 in the vertical direction. On the other hand, a support member 50 is formed on the lower portion of the main body frame 40 so as to protrude sideways, and a boss portion 52 having a perforation 51 penetrating in the vertical direction is formed at the tip of the support member 50. A spherical bearing 53 is held inside the perforation 51. The spherical bearing 53 has a locking rod 54 supported at its lower end so as to be swingable. The locking rod 54 extends upward and passes through the through hole 49 of the horizontal frame 44. The upper end portion protrudes upward from the upper surface of the horizontal frame 44.

  A spring receiving seat 57 is attached to the upper end protruding portion of the locking rod 54, and a compression spring 55 is attached between the spring receiving seat 57 and the lateral frame 44. A nut 56 is screwed onto the locking rod 54 above the spring seat 57, and the compression spring 55 is compressed by tightening the nut 56, and the horizontal frame 44 is moved to the main body frame by the elastic force of the compression spring 55. It is crimped to 40 via a slide plate 47.

  A trapezoidal engagement portion 58 is formed on the lateral frame 44 located below the inclination of the track so as to protrude inward of the traction frame 43 in plan view. On the other hand, the main body frame 40 is formed with a stopper 59 protruding upward at a position corresponding to the engaging portion 58 of the horizontal frame 44, and a laminated rubber 60 is provided between the stopper 59 and the engaging portion 58 of the horizontal frame 44. It has. The laminated rubber 60 is formed by alternately laminating rubber sheets and steel plates, and has a characteristic that it is easily deformed in a direction orthogonal to the traveling direction, although the deformation of the cart 30 is small in the traveling direction. Have.

  Next, the vertical frame 45 on both sides of the traction frame 43 is provided with a beam pin 61 projecting laterally at the center, and the beam 42 is pivotally attached to the beam pin 61 so as to be rotatable in the vertical direction. At both ends, a grinder 39 is pivotally attached so as to be rotatable in the vertical direction. As described above, the grinder 39 grasps the rope 12 extending on both sides of the carriage 30, and the carriage 30 is pulled by the rope 12.

  Next, the operation of the carriage 30 having the above configuration will be described. First of all, when the lengths of the ropes to be pulled by the left and right ropes 12 are the same, that is, when the carrier 10 is pulled in the direction of the summit direction (arrow B) by the same tension, the tension of the ropes 12 is grasped. The trolley 39 acts on the traction frame 43 via the beam 42, and the stopper 59 of the main body frame 40 is pressed from the engaging portion 58 of the traction frame 43 via the laminated rubber 60 to pull the entire carriage 30. As described above, since the slide plate 47 for reducing friction is interposed between the traction frame 43 and the main body frame 40, the frictional force between the traction frame 43 and the main body frame 40 is slight. The force pulling the carriage 30 is mainly the pressing force of the laminated rubber 60 acting on the stopper 59 of the main body frame 40. Further, in this case, since the tensions of the right and left ropes 12 are the same, the forces acting on the left and right of the tow frame 43 are the same, and the plan view shape of the tow frame 43 is kept rectangular as shown in FIG. Towed as it is.

  The above description is for the case of moving in the direction of the summit. However, in the case of moving in the direction of the summit, that is, in the direction opposite to the arrow B, the moving direction of the rope 12 is opposite, but the inclination of the track. Since the weight of the carrier 10 acts in the direction of the foothill, the force of the weight acts on each part, so that the shape of the carriage 30 is the same as above even when the carrier 10 moves in the direction of the foothill. .

  Next, for example, when an imbalance occurs in the tension of the right and left cable 12 during the movement of the transporter 10 due to a difference in pulley diameter of each drive pulley that drives the left and right cable 12 or poor synchronization. The tow frame 43 is deformed, and the right and left grinders 39 move back and forth to keep the tension in equilibrium. That is, as described above, the traction frame 43 has a link structure in which the end portions of the horizontal frame 44 and the vertical frame 45 are respectively connected by the pins 46, and the horizontal frame 44 and the vertical frame 45 facing each other on a horizontal plane are kept parallel. It can be deformed. In addition, since the traction frame 43 and the main body frame 40 are in contact with each other with the frictional force reduced through the slide plate 47, the traction frame 43 has a structure that can easily slide with respect to the main body frame 40. With such a configuration, when there is a difference in tension between the right and left ropes 12, the traction frame 43 is deformed into a parallelogram shape, so that the left and right grinders 39 move relatively in the front-rear direction. Thus, the tension of the right and left ropes 12 is balanced.

  Next, when the position of the rope 12 is shifted in the left-right direction for some reason, a force in the left-right direction acts on the grinder 39 that grips the rope 12. It is not preferable that the force acts on the main body frame 40. Therefore, in such a case, the following operation is performed so that a lateral force does not act on the main body frame 40. That is, as described above, the laminated rubber 60 interposed between the main body frame 40 and the traction frame 43 has a characteristic of easily deforming in the left-right direction of the left-right direction. Even when the compressing force is received, that is, when the transporter 10 is being pulled, the tow frame 43 can easily move in the left-right direction with respect to the main body frame 40. As a result, when a lateral force acts on the grinder 39 or the traction frame 43, the traction frame 43 slides relative to the body frame 40 in the lateral direction, and the lateral force acts on the body frame 40. There is nothing to do.

  As described above, the form in the case of applying the rope pulling type transportation facility to the sloping ground has been described, but the configuration of the carriage 30 in the case of traveling on a flat ground with little height difference will be described below. When operating on an inclined ground as described above, since the weight of the transporter 10 acts in the traveling direction, it was possible to tow by one horizontal frame 44 of the tow frame 43. When performing, it is necessary to make a traction force act in any direction before and behind the running direction. Therefore, in this case, in addition to the above-described configuration, the configuration including the engaging portion 58 formed on the horizontal frame 44 of the traction frame 43 and the laminated rubber 60 is also provided symmetrically on the opposite side frame 44. The configuration. That is, the other horizontal frame 44 is formed with a trapezoidal engaging portion 58 projecting inward of the traction frame 43 in plan view, and between the engaging portion 58 and the stopper 59 of the main body frame 40. The laminated rubber 60 is provided. With this configuration, even when operating on a flat track, it can be pulled in either the front or back direction, and the function for the behavior of the rope 12 is the same as described above, regardless of whether the vehicle is traveling back and forth. Can be demonstrated.
