Description

  The present invention relates to a vibration prevention structure for a slope elevator, and more particularly, to a vibration prevention structure for a slope elevator including an upper vehicle on which a person is boarded and a drive carriage that travels along a rail.

  2. Description of the Related Art Conventionally, slope elevators such as monorail cars convey a person boarding a vehicle when the vehicle moves up and down the slope. In particular, the present monorail car has a structure in which a rack is attached to the rail and a pinion engaged with the rack is driven by a motor in order to travel without slipping on a steel rail laid.

Further, in such a slope elevator, for example, as shown in Patent Document 1, it is composed of an upper vehicle on which a person is boarded, and a drive carriage (lower vehicle) that travels in conjunction with the upper vehicle, and is made of steel. It is common to run on steel rails with steel wheels.

  However, since the slope elevator as described above travels on steel rails with steel wheels, vibrations in the upper vehicle increase, and there is a risk of giving a feeling of uncomfortable riding to the boarding personnel. In particular, the vibration of the upper vehicle in the vertical direction tends to increase, and it is desired to reduce such vibration.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vibration prevention structure for a slope elevator that can mitigate vibrations of an upper vehicle.

  In order to achieve the above object, the present invention provides the following.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[Configuration of slope elevator]
1 to 3 show a monorail car 10 that is employed as a preferred embodiment of a slope elevator according to the present invention. 1 to 3 are schematic views showing the configuration of a slope elevator.

  As shown in FIG. 1, the monorail car 10 travels on a laid rail 20.

  The rail 20 is arranged with vertical square pipes having a substantially square cross section extended in the traveling direction, with a predetermined vertical interval, and is extended in the traveling direction. As shown in FIG. 1B, a rack 46 with teeth protruding downward is attached to the lower surface of the upper corner pipe of the rail 20. In addition, a power supply rail 42 made of a conductor is disposed on the upper corner pipe of the rail 20 so as to extend in the longitudinal direction.

  The monorail car 10 includes an upper vehicle 12 and a lower vehicle 14 as shown in FIG. The upper vehicle 12 is a vehicle including a cabin on which a person is boarded. The lower vehicle 14 is a vehicle having a driving device 18 that travels along the rail 20. Further, the lower vehicle 14 is provided with a holding portion 16 for holding the upper vehicle 12.

  As shown in FIG. 2, the lower vehicle 14 is provided with a cylinder 26 for tilting the holding portion 16 with the tilt shaft 24. The cylinder 26 is hydraulic and can be electrically expanded and contracted. As described above, the expansion and contraction of the cylinder 26 tilts the holding portion 16 and tilts the upper vehicle 12.

  Specifically, when the monorail car 10 is on the horizontal rail 20, as shown in FIG. 2A, the cylinder 26 is controlled to be contracted, and the monorail is placed on the rail 20 having a predetermined inclination angle. When the car 10 is present, the cylinder 26 is controlled to be extended as shown in FIG. Thus, the monorail car 10 can travel according to the inclination angle of the rails laid on the slope. In the present embodiment, the tilt angle is about 26 degrees, but the present invention is not limited to this.

  In this way, the upper vehicle 12 and the lower vehicle 14 are connected to be tiltable, and the lower vehicle 14 has a cylinder 26 (vehicle tilting portion) that tilts the holding portion 16 at an angle that makes the upper vehicle 12 horizontal. Since the upper vehicle 12 can be held horizontally, the vibration of the upper vehicle 12 in the vertical direction can be reduced even if the angle between the upper vehicle 12 and the lower vehicle 14 is not constant.

  As shown in FIG. 1B, the driving device 18 is provided with a traveling wheel 36 so as to abut from above the rail 20 and a guide wheel 37 so as to abut from the side. The drive unit 18 is provided with a pinion 34 that meshes with a rack 46 attached to the rail 20. Thus, the monorail car 10 is caused to travel by the traveling wheels 36, the guide wheels 37, and the pinions 34. The driving device 18 is driven by a motor 44 for driving the pinion 34 and the like.

  As shown in FIG. 2, the holding portion 16 is provided with a plurality of air springs 28 for holding the bottom plate frame 22 of the upper vehicle 12. The plurality of air springs 28 have elasticity in the vertical direction. The air spring 28 is a bellows type air spring. In the present embodiment, eight air springs 28 are disposed as shown in FIG. 3A, but the present invention is not limited to this.

  As described above, since the holding portion 16 that holds the upper vehicle 12 in the vertical direction is provided with the plurality of air springs 28 that have elasticity in the vertical direction, the natural frequency in the vertical direction of the upper vehicle 12 is lowered and is good. Thus, it is possible to obtain a vibration-proofing effect, and to mitigate vibrations in the upper vehicle 12.

  In the holding portion 16, as shown in FIGS. 1B and 2, oil dampers 30 are arranged at four locations on the front, rear, left and right sides of the holding portion 16 in the vicinity of the air spring 28. The oil damper 30 is a damper having elasticity in the vertical direction, and can relieve excessive vibration of the air spring 28 and shaking in the left-right direction.

  Further, as shown in FIG. 2, a rubber buffer 32 is disposed in the holding unit 16. As shown in FIG. 3A, the rubber buffer 32 is disposed at four locations on the front, rear, left and right sides of the holding portion 16 in the vicinity of the air spring 28. As shown in FIG. 3B, these rubber buffers 32 include a first rubber buffer 32a having elasticity in the front-rear direction (horizontal direction), a second rubber buffer 32b having elasticity in the left-right direction (horizontal direction), The third rubber buffer 32c is elastic in the vertical direction (vertical direction).

  As described above, since the holding portion 16 is provided with the rubber buffer 32 having elasticity in the horizontal direction, it is possible to alleviate the shake due to the impulse in the horizontal direction during traveling, deceleration, and stopping. In addition, since the holding portion 16 is provided with the rubber buffer 32 having elasticity in the vertical direction, it is possible to reduce the sinking at the time of sudden stop.

  In the holding portion 16, as shown in FIG. 1B, a rubber buffer 38 is also provided from below. The rubber buffer 38 has elasticity in the vertical direction (vertical direction). The rubber buffer 38 is supported by a support member 39 and is configured to come into contact with the holding portion 16 from below.

  As described above, since the holding portion 16 is provided with the rubber buffer 38 having elasticity in the vertical direction, it is possible to alleviate the lifting when the vehicle stops suddenly.

[Other Embodiments]
In the above-described embodiment, the pinion that meshes with the rack attached to the rail is provided and traveled by the pinion. However, the present invention is not limited to this, and travel may be performed in another manner.

  Furthermore, in the above-described embodiment, the upper vehicle and the lower vehicle are connected to be tiltable, and the holding unit is tilted at an angle that makes the upper vehicle horizontal. Even if it is not in a horizontal state, the holding portion may be tilted at a angle less than a specific tilt angle. Further, the upper vehicle and the lower vehicle may not be connected so as to be tiltable. For example, the upper vehicle and the lower vehicle may be connected so as not to be tiltable.

  As described above, some of the embodiments of the present invention have been described in detail with reference to the drawings. However, these are merely examples, and various embodiments can be made based on the knowledge of those skilled in the art including the aspects described in the section of the disclosure of the invention. The present invention can be implemented in other forms that have been modified or improved.
