Description

  The present invention relates to a door device provided in a vehicle of a cable car, and more particularly to a door device of a cable car vehicle that prevents the door of the vehicle from opening when the vehicle is running.

  A cable car connects a vehicle to both ends of a rope, wraps this rope around a pulley installed at the top of the mountain, and rotates the pulley to drive the vehicle along a rail laid on the ground. Many of them are used as a transportation for climbing slopes for sightseeing in high places and scenic visits to shrines and temples at the top of the mountain.

  A general cable car is roughly configured as follows. Two vehicles are arranged on a rail laid on an inclined surface, and travels back and forth between the foot-side stop and the summit-side stop along this rail. Each vehicle is connected to both ends of a single rope, and the rope is wound around a driving pulley provided on the summit side. The positional relationship between the two vehicles is such that when one vehicle is located at the stop on the summit side, the other vehicle is located at the stop on the mountain side. It is operated by the so-called vine method that travels in the direction.

  Since the cable car vehicle is towed and moved by the cable as described above, it does not have a driving device for traveling, and is not suitable for in-vehicle devices that require electric power such as interior lights. Electricity is supplied from a battery mounted on the vehicle or an overhead line stretched along the track. The door of the vehicle is opened and closed by electric power or aerodynamic force, and electric power for driving and controlling the door is also supplied from this battery or overhead wire. A crew member is on board the vehicle in order to monitor the track condition and cope with an emergency, and the opening and closing of the door of the vehicle is performed by the crew member operating keys and buttons in the vehicle. The technology related to the door of such a cable car vehicle is disclosed in Patent Document 1 as to a cable carrying device that is an approximate technical field.

  A crew room is provided at both ends of the vehicle. In this crew room, various operation switches such as a horn, an emergency brake, and an electric light are arranged and operated by the crew depending on the situation. As described above, the opening and closing of the door is also due to the operation of the crew, and there is no guarantee that there will be no human error such as a button that opens the door accidentally pressed during operation. Therefore, conventionally, the device is configured such that the door does not operate while the vehicle is moving, even if there is an erroneous operation such as a button for operating the door. For example, the vehicle is provided with a tachometer that is linked to the rotation of the wheels, and a signal from this tachometer is input to a control device that controls the opening and closing of the door. Some facilities are configured to determine whether or not the door can be opened and closed.

JP-A-5-270401

  However, devices such as the above-described tacho generator are expensive, and since they are precision devices, the calibration and overhaul of the output signal must be performed regularly, and maintenance and inspection are also expensive. In addition, there are equipments that do not originally have equipment such as the above-mentioned tachometer generator in the vehicle, and even if you try to install the equipment after such a vehicle, it can be installed depending on the installation space, wheel structure, etc. There was something impossible.

  The present invention has been made in view of the above circumstances, and is a cable car vehicle door device that can be easily applied even to an existing vehicle while having a low-cost configuration of equipment. The purpose is to provide.

  According to a first aspect of the present invention, in a cable car vehicle that is driven by a rope, the door operation switch that opens and closes the door of the vehicle and the rotation that detects the rotation of the wheel provided in the wheel portion of the vehicle are provided. A detector; a door engine that opens and closes the door; and a door control device that controls the operation of the door engine based on signals from the door operation switch and the rotation detector, and the rotation detector. Includes a rotation plate fixed to the wheel, and a detection sensor that outputs a pulse signal by the rotation of the rotation plate.

  According to a second aspect of the present invention, in the door device for the cable car vehicle according to the first aspect, the rotary plate has perforations formed at equal intervals on the same circumference.

  According to a third aspect of the present invention, in the door device for the cable car vehicle according to the second or third aspect, the rotation detector includes two detection sensors for one rotation plate. It is said.

  According to a fourth aspect of the present invention, in the door device for the cable car vehicle according to any one of the first to third aspects, the rotation detectors are individually provided on the different wheel portions.

  According to the present invention, the rotation of the wheel is detected by the rotation plate fixed to the wheel and the switch for detecting the rotation plate, and it is possible to detect the movement and stop of the vehicle without using expensive equipment and the like. Can be installed even in spaces. Further, since the rotating plate is configured to form perforations at equal intervals on the same circumference, it is easy to form and process perforations at arbitrary intervals, and the number of pulses of the pulse signal generated thereby can be reduced. It can be set appropriately, and the strength of the entire rotating plate is not significantly reduced.

  Furthermore, by having two detection sensors for one rotating plate, the door can be normally controlled by other detection sensors even if one detection sensor fails. By using a configuration in which the rotation detectors are individually provided on the different wheel portions, the door can be normally controlled even if a failure occurs in one rotation detector.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a cable car vehicle 10.

  The vehicle 10 is provided with wheels 11 so as to be rotatable, and a rope 14 is connected to the vehicle 10. The vehicle 10 is pulled by the rope 14 and travels on the rail 13. A crew member seat 15 is provided at both front and rear ends of the vehicle 10, and during operation of the vehicle 10, the crew member gets on the passenger seat 15 on the front side in the traveling direction to monitor the track and operate the equipment. The crew seat 15 is provided with an operation panel 16, on which various operation switches such as an emergency brake and a horn and operation switches for opening and closing the door 12 are arranged. A door 12 is provided on a side surface of the vehicle 10, and the door 12 is opened and closed by driving a door engine supplied with electric power from a battery mounted on the vehicle 10.

  Any one of the wheels 11 of the vehicle 10 includes a rotation detector that detects the rotation of the wheel 11. FIG. 2 is a side view showing the rotation detector 20, and FIG. 3 is a schematic front sectional view of the rotation detector 20.

  An axle 31 is fixedly supported between the wheel beams 30 provided on the carriage 32 of the vehicle 10, and the wheel 11 is rotatably supported on the axle 31 via a bearing 33. A disc-shaped rotating plate 21 is fixed to one side surface of the wheel 11 with a bolt 23 and rotates with the rotation of the wheel 11. A plurality of perforations 22 are formed in the rotating plate 21 at regular intervals on the same circumference.

  On the other hand, a bracket 24 in which a plate material is formed in a substantially crank shape when viewed from the front is fixed to the lower portion of the wheel beam 30 on the rotating plate 21 side. It is fixed in the 21 direction. The detection sensor 25 is disposed at a position facing the perforation 22 of the rotating plate 21, and is turned on or off as the perforation 22 passes, and a pulse signal is transmitted in proportion to the rotation of the wheel 11 or the rotating plate 21. To do. As the detection sensor 25, a non-contact type sensor such as a proximity sensor or a photoelectric sensor is used.

  FIG. 4 is a block diagram showing a control configuration of the door 12. The pulse signal generated by the rotation detector 20 is input to a door control device 34 that controls opening and closing of the door 12. In addition to the above pulse signal, the door control device 34 receives signals from a door operation switch 35 and a rotation detector invalid switch 37 provided on the operation panel 16. The door engine 36 that opens / closes and the travel indicator lamp 38 disposed on the operation panel 16 are controlled as follows.

  First, the door control device 34 determines whether or not the vehicle 10 is traveling based on the pulse signal from the rotation detector 20. For example, the number of pulses per unit time transmitted from the detection sensor 25 in the door control device 34 is counted, and if the pulse signal is not input for a set time or more, it is determined that the vehicle 10 is stopped. That is, when the pulse signal is input, it is determined that the vehicle 10 is traveling. When the vehicle 10 is determined to be stopped, when the door operation switch 35 is operated, the door control device 34 controls the door engine 36 to open and close the door 12. In this case, the door control device 34 performs control so that the travel indicator lamp 38 is turned off.

  On the other hand, when the vehicle 10 is determined to travel, the operation of the door operation switch 35 is disabled, and the opening / closing control of the door 12 is not performed even if the door operation switch 35 is operated. Further, in this case, the door control device 34 performs control so that the travel indicator light 38 is lit, so that the occupant can confirm that the rotation detector 20 is operating normally. Thus, in the door device of the present invention, whether or not the door can be opened and closed is controlled by detecting the actual rotation of the wheel 11, and even if the door operation switch 35 is erroneously operated while the vehicle 10 is traveling. The door 12 does not open.

  Next, when the rotation detector invalid switch 37 is operated, the door control device 34 can open and close the door 12 by operating the door operation switch 35 regardless of the presence or absence of the pulse signal of the rotation detector 20. Control to be. Thereby, the operation | movement confirmation of the door 12 at the time of a maintenance check etc. can be performed easily.

  In the above description, a configuration in which one detection sensor 25 is used for one rotating plate 21 is shown, but a configuration in which two detection sensors 25 are used may be employed. If comprised in this way, even if it is a case where any one detection sensor 25 fails, control can be performed based on the pulse signal of the other detection sensor 25, and safety | security increases further. Further, in addition to the configuration of the rotation detector 20 in one wheel 11, a similar configuration can be adopted for another wheel 11. If comprised in this way, even if any one rotating plate 21 or the detection sensor 25 is damaged or failed, it can control based on the signal of the rotation detector 20 with which the other wheel 11 was equipped. In any of the above cases, if a traveling indicator light 38 corresponding to each detection sensor 25 is provided on the operation panel 16, even if any one of the rotation detectors 20 breaks down, the crew member recognizes this failure. be able to.
