Description

  The present invention relates to a prime mover that drives a rope in a rope-type transport facility that operates by suspending or towing a carrier or a vehicle with a rope.

  The cable-type transport equipment is a ropeway or other cableway that operates by hanging a carrier on a cable stretched in the air, or a steel cable railway that operates by pulling a vehicle along the rail laid on the ground. Known as. These cableways and steel cable railways do not run with power to the vehicles themselves like railways, etc., but instead connect the vehicles and transporters to the ropes and drive the ropes to move the vehicles and transporters. Therefore, it is possible to transport personnel even on steep slopes, to visit shrines and temples in the mountains, transport personnel at mountainous tourist sites, and ski resort personnel It is widely used for transportation.

  The above ropeways and steel cable railways are generally provided with a prime mover equipped with a prime mover that drives the rope at a high-side stop, and at both ends of the rope wrapped around the prime mover, vehicles and vehicles A system called a crossing type is used in which the two are connected to each other and alternately reciprocate between the stops. The prime mover includes an electric motor and a speed reducer that drive the prime mover pulley, a brake that operates when the operation is stopped, and the like, and operates the carrier and the vehicle by comprehensively controlling them ( For example, see Patent Document 1).

JP 2008-201390 A

  In ropeways and steel cable railways that operate in the manner described above, there is an imbalance in the load acting on the rope on the upline side and the downline side depending on the number of people riding on the vehicle or carrier. . For example, when there is a facility for sightseeing purposes at the high altitude side, passengers are concentrated on the carrier or vehicle on the up line side during the operation start time, and the rope tension on the side pulling this is high, and the other side Will be in a state where the rope tension is relatively low. On the other hand, during the operation end time, passengers are concentrated on the down line carrier or vehicle, and the line tension on the connected side is high, while the opposite side, that is, the upstream line tension is low. It becomes.

  Such an unbalance of the rope tension becomes a problem when braking is performed while the vehicle or the carrier is traveling on the track. That is, in the prime mover that drives the rope, as soon as a control signal for stopping operation is issued, the electric power to the motor is cut off and the brake starts operating. Until the braking force is generated in the brake, However, although there is a slight time lag, a state in which neither the driving force nor the braking force acts on the driving pulley occurs even though it is a minute time, and the vehicle and the transporter become idle. At this time, if there is an unbalance in the above-described line tension, the distance and time required for braking differ depending on the unbalanced state. In particular, in the state where the line tension on the down line side is high and the line tension on the up line side is low, the vehicle and the carrier are accelerated instantaneously, resulting in a long braking distance.

  The present invention has been made in view of such circumstances, and is a rope type that can reduce the effect of braking due to the imbalance of the line tension and can reduce the distance that the vehicle or the carrier travels idle. It aims to provide a prime mover for transportation equipment.

In order to solve the above problems, the present invention provides a driving pulley that wraps a rope to drive the rope, a reduction gear connected to the driving pulley, an electric motor connected to an input shaft of the reduction gear, A brake that brakes the prime mover pulley, and with the movement of the rope, the vehicles respectively connected to both ends of the rope run in opposite directions, and the electric power to the motor is cut off. In addition, when starting the operation of the brake, there is a cable-type transportation facility in which neither a driving force nor a braking force acts on the driving pulley, and the output shaft of the motor or the speed reducer Two flywheels are superposed on the input shaft, and when the driving force and the braking force do not act on the driving pulley, the inertial force of the flywheel acts on the electric pulley. With features To have.

  According to the present invention, the inertial force is increased by providing the flywheel on the output shaft of the electric motor or the input shaft of the speed reducer, and the influence due to the imbalance of the rope tension during braking is reduced. The running distance is shortened.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. In the following description, an embodiment using a steel cable railway as a rope-type transport facility will be described, but the present invention can also be applied to a cableway such as a ropeway. FIG. 1 is an explanatory view showing an outline of a steel cable railway. In the figure, two vehicles 11 are arranged on a rail 10 laid on an inclined surface, and reciprocate along the rail 10 between a foothill side stop and a summit side stop. Each vehicle 11 is connected to both ends of one strip 18, and the middle of the strip 18 is wound around the driving pulley 12 and the driving pulley 13 of the prime mover 50 provided at the summit stop. ing. The positional relationship between the two vehicles 11 is such that when one vehicle 11 is located at the summit stop, the other vehicle 11 is located at the foot stop. 11 is operated by a so-called vine method that travels in opposite directions.

  The driving pulley 13 is driven by an electric motor 17. That is, the drive pulley 13 is connected to the output shaft 15 of the speed reducer 14, and an electric motor 17 is connected to the input shaft 16 of the speed reducer 14, and the drive pulley 13 is rotated by controlling the drive of the motor 17. Then, the rope 18 is wound and unwound. A disk plate 19 is fixed to the input shaft 16 of the speed reducer 14. A disk brake 20 acts on the disk plate 19 to brake the rotation of the electric motor 17 or the driving pulley 13. Further, a pulley brake 21 is provided at the peripheral edge of the driving pulley 13, and this pulley brake 21 acts on the peripheral edge of the driving pulley 13 to directly brake the rotation of the driving pulley 13. These disc brakes 20 and pulley brakes 21 are operated when the vehicle 11 stops at the stop, or when there is an abnormality in the equipment or the vehicle 11, and stops the operation of the steel cable railway.

  FIG. 2 is a plan view of the prime mover 50, and FIG. 3 is an AA arrow view in FIG. As described above, the prime mover 50 includes the driven pulley 12, the prime mover pulley 13, the speed reducer 14, and the electric motor 17. The rope 18 extending from the track in the direction of the arrow 18a is wound around the convection pulley 12 and the drive pulley 13 a plurality of times in order, and extends again in the direction of the arrow 18b into the track. The rope tension on the arrow 18a direction side and the rope tension on the arrow b direction side differ depending on the number of passengers boarding the vehicle 11 and the position of the vehicle 11 in the track. The driving pulley 13 includes a pulley shaft 22 that rotates as a unit. One end of the pulley shaft 22 is coupled to the output shaft 15 of the speed reducer 14 via a coupling 23. The input shaft 16 of the speed reducer 14 is connected to the output shaft of the electric motor 17 by a universal joint 24, and the rotation of the driving pulley 13 is controlled via the speed reducer 14 by controlling the driving of the electric motor 17.

  The input shaft 16 of the speed reducer 14 includes a disk plate 19, and a disk brake 20 that brakes the rotation of the disk plate 19 is installed on the outer periphery. A pulley brake 21 that brakes the rotation of the driving pulley 13 is installed at the peripheral edge of the driving pulley 13. Both the disc brake 20 and the pulley brake 21 are configured such that the disc plate 19 and the outer peripheral portion of the driving pulley 13 are sandwiched between the brake pads by the action of a spring force to be braked. By combining the hydraulic cylinders and applying hydraulic pressure thereto, the brake pad is opened and the braking force is released, and by releasing the hydraulic pressure, the braking force is applied. Therefore, there is a slight time lag until the disc brake 20 and the pulley brake 21 completely generate the braking force and until the braking force is completely released.

  FIG. 4 is a partial cross-sectional view showing a connecting portion between the speed reducer 14 and the electric motor 17. A yoke joint 26 is fitted on the input shaft 16 of the speed reducer 14, and a universal joint 24 is connected to the end surface of the yoke joint 26. A flange portion 27 is formed on the outer peripheral portion of the yoke joint 26 on the universal joint 24 side, and the disk plate 19 is fixed thereto. A yoke joint 28 is similarly fitted on the output shaft 25 of the electric motor 17, and a universal joint 24 is connected to the end face of the yoke joint 28. A flange portion 29 is formed on the outer peripheral portion of the yoke joint 28 on the main body side of the electric motor 17, and a flywheel 30 is fixed thereto. The flywheel 30 is formed of a steel material in a disc shape and has a predetermined mass. In the figure, the flywheel 30 is formed by superposing two disc-shaped steel materials.

  The flywheel 30 increases the inertial force during braking, and has the following effects. That is, when the braking force is constant, the braking distance and the braking time are such that the tension difference between the rope 18 on the winding side and the feeding side, the driving pulley 13 around which the rope 18 is wound, the reduction gear 14, the electric motor 17, etc. And the time until the disc brake 20 and the pulley brake 21 generate the braking force completely. Therefore, there is a difference in braking distance and braking time between the case where the tension difference of the rope 18 is large and the case where it is small, but the inertial force is increased by providing the flywheel 30 having a predetermined mass as described above. Therefore, the influence on the braking force due to the tension difference of the rope 18 is relatively reduced, and the distance of idling is also reduced, and the variation in the braking distance and the braking time due to the tension difference of the rope 18 is reduced. In the above description, the flywheel 30 is provided on the output shaft 25 of the electric motor 17. Needless to say, the flywheel 30 may be provided on the input shaft 16 of the speed reducer 14.
