Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrier transfer device for transferring a carrier that has released a rope at a stop of an automatic circulation type cableway on a rail.

[0002]

[Prior art]

 The driving force of the transfer device for decelerating transfer, accelerating transfer and forwarding transfer of the carrier that released the rope that circulates at high speed for passengers getting on and off at the stop of the automatic circulation ropeway is to wind the rope. It has a structure in which a sprocket wheel is fitted concentrically with the driving pulley described above, the driving force is taken out by the chain and transmitted to the transfer tire by the reduction gear and the propeller shaft, and a dedicated electric motor for driving the transfer device is provided. For example, there is a device that detects the moving speed of the cord and controls the number of rotations so that the carrier has a predetermined transfer speed.

However, in the transfer device of the former configuration, the transmission path of the driving force becomes long, and when the driving pulley also functions as a tension device, the transfer device moves in the cableway direction, The positional relationship with the transfer tires arranged along the rail and pivotally attached changes. Therefore, since it is necessary to make the structure capable of coping with this, the driving force transmitting portion has a complicated and large-scale structure. In the latter structure, which has a dedicated electric motor to obtain the driving force, a detector for detecting the transfer speed and a controller for adjusting the rotation speed of the electric motor by the speed signal from the detector are required. become.

[0004]

[Problems to be solved by the device]

 As described above, the structure of the mechanical device for obtaining the driving force for transferring the carrier at a predetermined speed in the conventional stop tends to be a large-scale and complicated device. This is because the rigging machine of the transporter is operated by gripping and releasing the rope, so it is necessary to make the transport speed of the rope and the transporter speed uniform at the gripping or releasing position. Since the carrier is transferred based on the moving speed of the rope, a long propeller shaft is installed to rotate in a narrow space, and it is covered with a cover for safety. It was necessary and hindered maintenance and inspection. Also, in the case of a drive device using an electric motor, the entire device can be made small, but it is somewhat inferior to the device of mechanical interlocking structure in terms of reliability with respect to speed tuning of the carrier and the rope in the event of an abnormality. There was a problem.

In order to solve the above-mentioned problems, the present invention does not use an electric motor dedicated to a transfer device, and simplifies the structure to reduce the size, and has reliability in speed tuning of the rope and the carrier. Then, it is to provide a driving force take-out device for transporting a carrier, which has performance equivalent to that of the conventional device.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a driving force take-out device for transferring a carrier that has released a rope on a rail arranged at a stop of an automatic circulation type cableway, in which the rail is provided inside the stop. Of a plurality of receiving wheels arranged side by side to guide the rope along the rails, two drive pulleys fitted to the respective rotating shafts of a pair of adjacent receiving wheels, and above the rail. A transfer tire that is arranged in parallel with the transfer tire and rotates by pressing the gripping device of the transporter; and a transfer pulley that is located on a vertical line approximately midway between the two drive pulleys and is pivotally attached to and connected to the transfer tire. A belt for transmitting the rotational force of the two drive pulleys to the transfer pulley, and a driven pulley that is positioned above the transfer pulley and is movably pivoted up and down to adjust the tension of the belt. And the rotation of the receiving ring described above due to the movement of the rope. The so as to transfer the carriage is transmitted to the transfer tire.

[0007]

[Action]

 Of the multiple receiving wheels that make up the receiving device for supporting and guiding the ropes that circulate in the automatic circulation cableway stop, each rotating shaft fitted with adjacent receiving wheels is driven. Fit the pulley. Next, a transfer pulley is fitted on the shaft of the transfer tire for transferring the gripping machine of the carrier, which has released the rope with the rails arranged in the stop, by frictional force. Furthermore, a driven pulley that can move up and down is fitted over the transfer pulley.

Next, the belt is wound around the two drive pulleys, the transfer pulley, and the driven pulley, and the driven pulley is moved upward to apply tension to the belt. As a result, a frictional force is generated between the two drive pulleys and the transfer pulley and the belt, which is opposed to the transfer force of the carrier. Further, depending on the diameter ratio of the groove of the belt between the drive pulley and the transfer pulley, the carrier is set to have a predetermined moving speed based on the moving speed of the rope.

In this way, the mechanism for obtaining the driving force of the acceleration transfer device, the deceleration transfer device and the forward transfer device can be simplified and downsized. In addition, since the moving speed of the rope is used as a reference, even if the operating speed of the carrier, that is, the moving speed of the rope is changed, when the carrier departs from the stop, it is accelerated and transferred by the acceleration transfer device. It also ensures that the speed is synchronized when squeezing.

The rail 6 and the rail 7, which are U-shaped or horseshoe-shaped in a plan view, are decelerated, forwarded, and accelerated, and passengers get on and off during this period.

The foothill stop 2 and the summit stop 3 have a structure in which the left and right sides are substantially symmetrical in plan view, and the transfer of the carriers 9, 9, ... Is performed in substantially the same state. The situation of transfer of the carriers 9, 9, ... At the stop 2 will be described.

FIG. 2 is a plan view showing an enlarged view of the foothill bus stop 2 shown in FIG. 1, and illustrates a more detailed situation regarding the transfer of the carriers 9, 9, .... Along the U-shaped rope 6 arranged at the foothill stop 2, the deceleration transfer device 20 on the arrival side, followed by the semi-circular forwarding transfer device 21 along the pulley 4, and further on. An acceleration transfer device 22 is provided on the departure side.

In this way, the carrier 9 that has now grasped the rope 8 and arrived at the foothill stop 2 from the direction of the arrow 13 of the cableway line 14 releases the rope 8 and moves it to the carrier 9 a by the deceleration transfer device 20. Then, it is decelerated and transferred to a low speed or a very low speed. Next, the passenger is alighted from the low-speed carrier 9a, and the carrier 9a becomes empty. The emptied carrier 9a is circulated and transferred at a low speed on the semicircular rail 6 as the carrier 9b by the transfer and transfer device 21 and turned to the outgoing side. When the carrier 9b is forwarded and transferred at a low speed to the rail 6 on the departure side, passengers waiting at the boarding position board. When the carriage 9b, on which the passengers have finished riding, is accelerated and transferred as the carriage 9c from the acceleration transfer device 22 to reach the same degree as the circulating rope 8, the rope 8 is gripped again and the rope is guided in the direction of arrow 11. Depart for track 14.

Next, the deceleration transfer device 20 for transferring the carriers 9, 9, ... In the stop, the driving transfer device 21 for obtaining the transfer force incorporated in the transfer transfer device 21 and the acceleration transfer device 22. The detailed structure of the part will be described with reference to FIGS. What is shown in the figure is a driving force output device 15 incorporated in the acceleration transfer device 22.

Among the rope receiving devices arranged to support and guide the ropes 8 along the route in which the ropes 8 circulate at a high speed at the foot of the foothold 2, the ropes attached to the accelerating transfer section on the departure side. A pair of adjoining receiving wheels 36 for supporting and guiding the rope 8 and driving pulleys 45, 45 which rotate integrally with the receiving wheel 36 are fitted to the receiving device.

FIG. 4 shows the detailed structure in a partial cross section. The wheel core 37 of the receiving wheel 36 is brought into close contact with the rotating shaft 41 by the clamp bush 39. A drive pulley 45 is fitted on a shaft end portion 41a on the side opposite to the side where the wheel core 37 is fixed, and further, a washer 46 is pressed from the outside to prevent the bolt 47 from coming off. In this way, the rotary shaft 41 having the receiving ring 36 fixed to one end and the drive pulley 45 fixed and fitted to the other end is rotatably attached to the housing 42 by the bearing 43 and the bearing 44. The drive pulley 45 is similarly fitted to the rotary shaft 41 for the other receiving wheel 36.

Next, to push and rotate the traction plates 61 1, 61, ... of the gripping machines 60, 60, ... of the transporters 9, 9, ... To accelerate and transfer the transporters 9, 9 ,. One of the plurality of transfer tires 23, 23, ... Constituting the acceleration transfer device 22 is attached with a pulley 25 for transmitting rotation to a tire shaft 24 to which the transfer tire 23 is attached, and by a nut 27. Prevents the tire shaft 24 from coming off. Further, a flange portion 28a is formed on the drive shaft 28 on the side surface of the pulley 25, and the end surface is joined by a bolt (not shown) so as to be positioned concentrically. Next, a transfer pulley 29 is fitted to the shaft end portion 28b on the opposite side where the flange portion 28a is formed, and a washer 30 is attached from the outside of the transfer pulley 29 to hold it with a bolt 31 to prevent it from coming off. In this way, the transfer tire 23 and the transfer pulley 29 are integrated. In this way, the drive shaft 28 in which the transfer tire 23 and the transfer pulley 29 are concentrically provided and integrated with each other is rotatably supported by the bearings 33 and 33 mounted in the housing 32 with the collar 34 interposed therebetween. To wear.

Further, a driven pulley 49 is provided above the transfer pulley 29. The structure of the driven pulley 49 is such that the shaft 52 is rotatably attached to the housing 54 by bearings 53, 53. The driven pulley 49 is attached to the shaft end of the shaft 52, the washer 51 is attached from the outside, and the bolt 50 presses the washer 51. The housing 54 pivotally attached to the driven pulley 49 is moved upward to tension the belts 48, 48, and then fixed to the bracket 68 by bolts 55, 55, 55, 55.

Thus, the two grooves formed on the two drive pulleys 45, 45, the transfer pulley 29, and the driven pulley 49 are located in the same plane, and as shown in FIG. The endless belts 48, 48 are fitted into the belt and wound about half a turn.

A plurality of transfer tires 23, 23, ... Which are arranged in the same row as the transfer tire 23 that rotates integrally with the above-mentioned transfer pulley 29, have two grooves, a large-diameter groove 25a and a small-diameter groove 25b. 25, 25, ... Are mounted on the same core. At this time, in the case of the acceleration transfer device 22 shown in FIG. 3, the pulleys 25 adjacent to each other in the direction of the arrow 11 which is the moving direction of the rope 8 are arranged in the order of combination of the large diameter groove 25a and the small diameter groove 25b. The belt 26 is wound endlessly. In the same manner, the belt 26 is sequentially wound around the combination of the large diameter groove 25a and the small diameter groove 25b. That is, regarding the pair of transfer tires 23, 23 adjacent to each other, the transfer tire 23 located on the side on which the carrier 9 advances rotates faster. Thus, in FIG. 3, the rotation of the transfer tires 23a, 23b, 23c, and 23d becomes faster in this order. Based on the rotation of the transfer tire 23c that rotates integrally with the transfer pulley 29, the transfer tire 23d located on the right side in the figure rotates faster, and the transfer tires 23a and 23b located on the left side rotate slowly. To do.

As shown in FIG. 3, when the rope 8 moves in the direction of the arrow 11, the ropes 36, 36 that come into contact with the rope 8 and guide the rope 8 are supported by the rubber tires 38, 38. The frictional force generated between the cord 8 and the cord 8 rotates in the directions of the arrow 57 and the arrow 57. As a result, the rotary shafts 41, 41 frictionally joined to the wheel cores 37, 37 by the clamp bushes 39, 39 and the drive pulleys 45, 45 fitted to the shaft end portions 41a, 41a also rotate integrally. As a result, the rotational force is transmitted by the belts 48, 48 wound around the drive pulleys 45, 45, the transfer pulley 29 rotates in the direction of arrow 56, and the drive shaft 28 and the transfer pulley 29 rotate in the direction of arrow 56. Then, the pulley 25 and the tire shaft 24 rotate, and the transfer tire 23c rotates. At the same time, the rotation of the transfer tire 23c is sequentially transmitted to the adjacent pulleys 25, 25, ... By the belts 26, 26, ... And the transfer tires 23a, 23b and 23d rotate.

As shown in FIG. 5, the transfer tires 23, 23, ... sequentially press and rotate the traction plate 61 fixed to the upper surface of the gripping machine 60 as the carrier 9 moves, thereby gripping the traction plate 61. The traveling wheels 62, 62 of the rope 60 roll and roll on the rail 6 having a concave cross section, and the carrier 9 is accelerated and transferred. At this time, by moving the driven pulley 49 in the direction of arrow 59 as shown in FIG. 3, the belts 48 and 48 are tensioned to increase the frictional force generated between the drive pulley 45 and the transfer pulley 29 and the belts 48 and 48. The belts 48, 48, the drive pulley 45, and the transfer pulley 29 are prevented from slipping when the carriers 9, 9, ... Are accelerated and transferred.

Next, when the rubber tires 38, 38 of the receiving wheels 36, 36 come into contact with the cord 8 and wear over time and the outer diameter of the rubber tires 38, 38 decreases, the movement amount of the cord 8 is reduced. The number of rotations of the drive pulleys 45, 45 increases, so that the transfer pulley 29, which is transmitted by the belts 48, 48 and rotates, and the transfer tire 23c connected to the transfer pulley 29 also rotate faster. Further, with the pulley 25 of the transfer tire 23c as the starting point of the driving force, the rotation of the transfer tires 23, 23 ,. When the transporters 9, 9, ... arrive at the stop and are decelerated and transferred by the deceleration transfer device 20, or when the transporters 9, 9, ... are accelerated and transferred by the acceleration transfer device 22 from the stop. Moreover, the speed synchronization with the rope 8 that circulates at a high speed is gradually lost. As a result, the carriers 9, 9, ... Are likely to be incompletely released upon arrival and incompletely grasped upon departure. Therefore, when the rubber tires 38, 38 of the receiving wheels 36, 36 are worn, the rubber tires 38, 38 must be replaced. However, as shown in FIG. 5, since the receiving wheels 36, 36 are arranged in a narrow space between the rail 6 and the drive pulley 45, it is necessary to have a structure that allows easy attachment / detachment.

FIGS. 6 to 8 are cross-sectional positive views for explaining the action of the clamp bushes 39 and 39 used for integrally joining the receiving wheels 36 and 36 shown in FIGS. 3 and 4 to the rotary shafts 41 and 41. It is a side view and a side view. Hereinafter, one receiving ring 36 will be described because the receiving rings 36, 36 have the same structure. A taper hole 37a is formed at the center of the wheel core 37 that constitutes the receiving ring 36, and the end face 37b is formed. Screw holes 37c, 37c, ... Are drilled at six positions on the circumference concentric with the tapered hole 37a at equal intervals.

Next, the clamp bush 39 is formed with a tapered portion 39b that fits into the tapered hole 37a formed in the wheel core 37, and as shown in FIG. Holes 39d, 39d, ... are drilled at six positions so that they are at the same positions as the screw holes 37c, 37c, ... drilled on the end face 37b of the wheel core 37, and further, three holes are screwed on the same circumference. Holes 39e, 39e, 39e can be drilled. Further, as shown in FIG. 8, a slit 39c is formed at one location on the circumference, and has a structure in which it is elastically deformed in the directions of arrows 71 and 72.

The procedure or operation for attaching or detaching the receiving wheel 36 to or from the rotating shaft 41 by using the clamp bush 39 formed in this way will be described. When the receiving ring 36 is attached to the rotating shaft 41 shown in FIG. 6, first, the clamp bush 39 is attached to the tapered hole 37a of the wheel core 37, and the holes 39d, 39d, ... Align with the screw holes 37c, 37c, ... Of the core 37 and turn the fixing bolts 40, 40 ,. Next, the receiving ring 36 having the clamp bush 39 attached to the wheel core 37 as described above is attached to the rotating shaft 41, and the rope 8 is supported at the center of the rubber tire 38 as shown in FIG. After positioning in the axial direction as much as possible, tighten the six fixing bolts 40, 40, ... Installed between the clamp bush 39 and the wheel core 37 with equal force in the order diagonally positioned. wear. At this time, the taper portion 39b of the clamp bush 39 bites into the taper hole 37a of the wheel core 37 in the direction of the arrow 70, and the radial component force generated at that time causes the taper portion 39b of the clamp bush 39 to taper as shown in FIG. The portion 39b is elastically deformed in the directions of the arrow 71 and the arrow 72, the clamp bush 39 and the rotating shaft 41 are in close contact with each other, and the receiving ring 36 and the rotating shaft 41 are integrally fastened.

Next, when removing the receiving ring 36 from the rotating shaft 41, first, loosen the six fixing bolts 40, 40, ... Between the clamp bush 39 and the wheel core 37 to remove. Further, the three fixing bolts 40, 40, 40 among them are reattached to the screw holes 39e, 39e, 39e formed at the three places shown in FIG. 8 and rotated, and as shown in FIG. Abutting on the end surface 37b. From this state, when the stop bolts 40, 40, 40 are further rotated to generate a thrust force at the screw portion, the reaction force causes the clamp bush 39 to move in the direction of the arrow 69 and the tapered portion 39b to move the wheel core 37. At the same time that the slit 39c formed in the taper portion 39b spreads in the directions of the arrows 73 and 74 due to the elastic restoring force, the clamp bush 39 and the rotary shaft 41 are easily moved out of the tapered hole 37a. The contact state is released by separating the receiving shaft 36 from the rotary shaft 41.

In this way, by using the clamp bush 39, fine position adjustment in the axial direction is possible, the cord 8 is supported at the center of the rubber tire 38 to prevent slippage, and the rotary shaft The receiving wheel 36 is fixed to 41 in an integral relationship so that the rotational force of the receiving wheel 36 caused by the movement of the rope 8 is transmitted to the drive pulley 45.

[Effect of device]

 Due to the large transport capacity of the automatic circulation cableway, the number of construction bases has increased dramatically in recent years. However, at the stop, since the carrier unleashes the rope, it is necessary to separately provide a rail for the carrier to travel and a transfer device for transferring the carrier, and the mechanical device installed at the stop is complicated. It will be massive.

The present invention is a transfer device for transferring a carrier in the above-mentioned stop, and particularly, the mechanical structure of a portion for obtaining a driving force is downsized and simplified. That is, on the route where the rope moves at high speed in the stop, two receiving wheels that are frictionally driven in contact with the rope are arranged side by side in the moving direction of the rope. Further, a drive pulley is further fitted to the rotary shaft to which each of the receiving wheels is fitted by using a clamp bush. Next, for the transfer tire that is designed to transfer the transfer device by pressing and rotating the gripping device of the transfer device, in addition to the pulley for transmitting the rotation to the adjacent transfer tire, Fit the transfer pulley onto the core. A driven pulley is pivotally mounted above the transfer pulley so as to be vertically movable. In this way, the rope that moves at high speed in the stop rotates the receiving wheel, and the driving force of the receiving wheel generated at this time is transmitted by the belt to rotate the transfer tire and transfer the carrier. Is. As a result, the transmission path of the driving force can be shortened as compared with the conventional one, so that the entire transfer device can be downsized. Further, since the rotation of the receiving wheel due to the movement of the rope is transmitted to the transfer tire by the belt, there is an effect that the drive force take-out device can have the same structure regardless of whether or not there is a tension device at the stop. In addition, since it has a mechanically connected structure, the transfer speed also changes in response to changes in operating speed, so there is reliability in terms of safety.
