Description

  The present invention relates to a rope pulling type transportation facility for towing and transporting a vehicle with a rope, and more specifically, when a normal operation is stopped in an emergency, a rescue driving apparatus that drives a vehicle carrying passengers to a stop. About.

  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. In this case, it is also possible to configure the carriage so that it is connected to an arbitrary position of the rope by gripping and releasing the rope by means of a gripping machine (for example, Patent Documents). 4).

  In such a rope pulling type transportation facility, in preparation for when the vehicle stops on the track due to equipment failure etc. and becomes inoperable, a stairway and a passage are provided as a retreat path on the side of the rail, Passengers can walk and evacuate (see, for example, Patent Document 5).

  By the way, such a rope pulling type transportation facility is mostly installed and used outdoors, and is often provided on an inclined land as described above. Therefore, when using the above-mentioned retreat route under such conditions, it is necessary to pay attention especially to walking of children and the elderly, and in the case of rain, etc., further attention is required. Therefore, in the case where such normal operation becomes impossible, if the vehicle can be moved without driving by pulling the rope, the passenger can be safely accommodated at the stop.

  The present invention has been made in view of such circumstances, and provides a rescue driving device for a rope pulling transportation facility capable of moving a vehicle on a railway line when normal operation becomes impossible. The purpose is to provide.

  According to the first aspect of the present invention, there is provided a cable pulling-type transport facility that operates by pulling a carrier with a rope on the installed rail, a rack rail laid along the rail, and the rack provided in the carrier. A pinion that meshes with the rail, an electric motor that drives the pinion, an electric storage device that converts electric power by an inverter and supplies electric power to the electric motor, and a charge control that charges the electric storage device by controlling electric power from the electric motor And a control device for controlling the inverter.

  The invention according to claim 2 is the rescue operation device for the rope pulling transportation facility according to claim 1, wherein an electric system that charges the power storage device, and the power storage device to the electric motor via the inverter It is characterized in that it can be switched to an electric system that supplies electric power.

  Further, the invention of claim 3 is the rescue operation device for the rope pulling type transportation facility according to claim 1 or claim 2, wherein a detection piece is fixed at a predetermined position in the track, A position detector that detects a detection piece and transmits a signal to the control device, and a rotary encoder that transmits a rotation signal of the pinion or the electric motor to the control device are provided.

  According to the first aspect of the present invention, when the normal operation becomes impossible, the transporter can move by itself. According to the second aspect of the present invention, charging is not performed when the voltage of the power storage device is equal to or higher than a specified value, so that the load on the synchronous motor is reduced. Moreover, according to the invention of Claim 3, when driving | running with a synchronous motor, automatic driving | operation becomes possible.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal section of a track showing an example of a track of a 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 order to hold the position of the rope 12 in the track, a receiving guidance roller 16 and a pressure guidance roller 17 are arranged to support the rope 12.

  FIG.2 and FIG.3 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 are rotatably provided at four lower and left and right lower end portions of the carriage 30, which roll along the rail 11 and travel. The passenger car 32 is swingably attached to the suspension frame 38 via the suspension machine 31, and the attitude of the passenger car 32 is kept horizontal even if the gradient of the track changes.

  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.

  4 and 5 are a side view and a plan view of the carriage 30. A rack rail 40 is laid in parallel with the rail 11 between the left and right rails 11. The rack rail 40 may be a normal rack in which teeth are continuously formed in the longitudinal direction, but is a pin rack in this embodiment. That is, as shown in FIG. 6, the rack rail 40 is obtained by fixing rack pins 40b having a circular or trapezoidal cross section at regular intervals between left and right U-shaped steel members 40a arranged in parallel. A pinion 41 is rotatably supported on the carriage 30, and the pinion 41 is engaged with the rack rail 40.

  A pinion shaft 42 is fitted to the pinion 41. The pinion shaft 42 is rotatably supported by a bearing 43, and the pinion 41 and the pinion shaft 42 rotate together. Both ends of the pinion shaft 42 protrude to the outside of the bearing 43, a rotary encoder 44 for measuring the rotation of the pinion shaft 42 is attached to one shaft end, and the output shaft of the speed reducer 45 is attached to the other shaft end. It is connected. A brake built-in type synchronous motor 46 is connected to the input shaft of the speed reducer 45, and the shaft of the motor 46 and the pinion 41 rotate in synchronization. The rotary encoder 44 may be attached to the counter load side of the rotating shaft of the synchronous motor 46.

  Further, the cart 30 includes an inverter 47, a power storage device 48, and a control device 49, which are electrically connected. FIG. 7 is an electrical system diagram showing these connections. The synchronous motor 46 is connected to an inverter 47 through a contact 52, and the inverter 47 is connected to the power storage device 48 through a contact 53. The circuit branches between the synchronous motor 46 and the contact 52, and a power storage device 48 is connected to the branched side via the contact 51 and the charge control device 50. A control device 49 is connected to the inverter 47, and the control device 49 controls the inverter 47 based on signals from the rotary encoder 44 and a position detector 54 described later.

  In such a circuit configuration, each device operates as follows. First, at the time of normal operation, that is, when the transporter 10 is operated by being pulled by the rope 12, the contact 51 is closed and the contact 52 and the contact 53 are opened in the electric circuit. When the transporter 10 moves, the pinion 41 rotates, thereby rotating the synchronous motor 46 and generating AC power. The charge control device 50 includes a rectifier circuit, a voltage control circuit, and the like. When the voltage of the power storage device 48 is lower than a specified value, the power generated by the synchronous motor 46 is energized to charge the power storage device 48 and When the voltage of the device 48 is higher than the specified value, control is performed so that the power storage device 48 is not charged. As a result, when charging is not performed, the load on the synchronous motor 46 is reduced, and the power storage device 48 can always maintain a state in which the specified power is stored.

  Next, when normal operation becomes impossible due to some abnormality, the operation of the transporter 10 can be performed as follows. In the electric circuit, the contact 51 is opened and the contact 52 and the contact 53 are closed. As a result, power is supplied from the power storage device 48 to the inverter 47, and the inverter 47 is controlled to supply power to the synchronous motor 46. At this time, the brake of the synchronous motor 46 is operated so that the synchronous motor 46 does not rotate.

  Next, the grinder 39 of the transporter 10 is opened, and the connection between the rope 12 and the transporter 10 is released. At this time, since the synchronous motor 46 is braked as described above, the transporter 10 does not move. Subsequently, when an operation start signal is transmitted to the control device 49 by a push button or the like provided on the transporter 10, the control device 49 starts control of the inverter 47 and releases the brake of the synchronous motor 46. The synchronous motor 46 that has been supplied with power from 47 rotates and the transporter 10 moves.

  The control device 49 automatically generates a speed pattern based on a signal from the rotary encoder 44, and controls the inverter 47 based on this, for example, as follows. In the traveling track, a detection piece 55 is fixed at a predetermined distance from the transporter stop position of the stops 18 and 19 (see FIG. 7). When the transporter 10 passes this position, the position detector 54 detects the detection piece 55 and transmits this signal to the control device 49. The control device 49 receives this signal, generates a deceleration pattern, controls the inverter 47 by comparing the signal from the rotary encoder 44 with the deceleration pattern, decelerates the transporter 10, and then stops the stop 18. , 19 automatically stops the transporter 10. At this time, simultaneously with the stop of the transporter 10, the brake of the synchronous motor 46 is operated to hold the transporter 10 in a fixed position. According to this configuration, automatic operation of the transporter 10 is possible.

  In the above description, the operation is performed by driving the synchronous motor 46. However, when the transporter 10 is lowered on the inclined track, the operation is as follows. In this case, the synchronous motor 46 is operated as a generator, and the regenerative power is controlled to control the speed of the transporter 10. As shown in FIG. 7, a resistor 57 is connected between the inverter 47 and the power storage device 48 via a braking unit 56, and when the regenerative power is generated in the synchronous motor 46, the braking unit 56 detects this. Then, the regenerative power is led to the resistor 57 and consumed. As a result, a braking force is generated in the synchronous motor 46, and the speed of the transporter 10 is controlled by controlling the braking force.

  Thereafter, when returning to normal operation, the operation opposite to the above may be performed. That is, the grinder 39 of the transporter 10 is grasped by the rope 12, the contacts 51, 52, 53 are returned to the normal operation state, and then the brake of the synchronous motor 46 is released. Thus, it is possible to return to the normal operation state very easily.

  As mentioned above, although embodiment by the carrier 10 which can hold and control the rope 12 was demonstrated, also in the rope pulling type | formula transport equipment which adheres the rope 12 to the carrier 10a as follows and operates. It can be implemented.

  FIG. 8 is a schematic view of a sword-type rope pulling type transportation facility. One end of the rope 12 is fixed to the carrier 10a traveling on the rail 11a. The rope 12 is wound around a drive pulley 60 provided at an upper stop, and then folded back down the track again, and a counterweight 61 is fixed to the other end. With this configuration, by driving the drive pulley 60 forward or backward, the transporter 10a and the counterweight 61 reciprocate in opposite directions. The configuration of each device such as the rack rail 40 laid on the track and the pinion provided in the transporter 10a is the same as described above.

  With this configuration, if any abnormality occurs during normal operation, the drive pulley 60 is braked to stop the operation. In this case, first, the brake of the synchronous motor 46 provided in the carrying device 10 is operated to stop and hold the carrying device 10 as described above, and the contacts 51, 52, 53 to the side supplying power to the synchronous motor 46. Switch. Next, a brake or the like acting on the drive pulley 60 is released to make the drive pulley 60 rotatable. Thereafter, the inverter 47 is controlled to start the operation of the transporter 10a. In the case of this embodiment, since the load of the transporter 10a is offset by the counterweight 61, the energy for moving the transporter 10a can be less than that of the previous embodiment, and thus the devices such as the synchronous motor 46 and the power storage device 48 The class can be configured with a lower performance than that of the above embodiment.
