BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rescue device in cableway equipment for rescue of passengers from a carrier in an emergency in the field of cableway equipment.

[0002]

2. Description of the Related Art In a cableway, a rope is wound between pulleys at both ends, and a carrier can be attached to and detached from the rope, or
It is a facility that is fixed semi-permanently and transports by moving a rope and moving a carrier, using a passenger car type or a chair type as a carrier, for transporting skiers at ski resorts, or in mountain sightseeing areas It is often used for passenger transportation. In addition, recently, it is also intended to be used for general traffic in cities and general traffic in the area.

Since such cableway equipment is operated at a high place, it is necessary to promptly accommodate passengers when the operation is stopped due to a power failure or the like. For this reason, the stop is generally equipped with a backup drive means, and in an emergency, the emergency drive of the cableway equipment is carried out by this, and the equipment is equipped to carry passengers together with the carrier. However, in the case of a failure of the drive system, operation of the cableway equipment itself becomes impossible, and rescue must be performed by means such as a rescue device.

As a rescue device or instrument in such a case, generally, a descender and a rescue bag are used to lower the passenger. That is, when the conductor is on board the carrier, the rescue equipment should be provided in advance in the carrier, and if necessary, the conductor should operate to accommodate passengers in the rescue bag and To lower it. This descender is used for escape during a fire or the like, and a device equipped with a speed control function is used so that the descending speed does not accelerate beyond a certain value. Although this method or device has the advantage of being economical, it has drawbacks such as making passengers feel uneasy at high places, taking a long time to perform rescue work, and having a large work load on staff involved. In addition, in cableway equipment with a relatively small number of passengers in the carrier, the conductor is generally not on board the carrier, so in this case, the staff will use the suspension vehicle etc. Along the way, it rolls down and arrives, and the rescue work described above is performed. In this case, there is a problem that the rescue time becomes longer than that in the previous case, and the work load of the staff engaged in the rescue is particularly heavy.

In order to improve this, an apparatus or method for separately providing a rescue carrier has been proposed. For example, Japanese Patent Publication No. 47-34849, “Rescue work method for overhead cableway”, describes a device separately provided with a rescue carrier in the case of a crossover cableway. In this device, a rescue vehicle other than this is run from the mountaintop side or high-altitude side of the rope along the support line for guiding the service of the service carrier to bring the passenger closer to the service carrier, It is designed to be transferred from a regular carrier to a rescue carrier. However, this device or method requires that a single carrier is used for each vertical line.
It can be used in the case of a crossover cableway equipment having only a stand, but cannot be used in the case of a circulating cableway having a large number of service carriers.

Further, in Japanese Patent Laid-Open No. 2-204161, "Gondola Lift Rescue Device", there is proposed a rescue device or method including a rescue carrier for use in a circulation type cableway. The rescue carrier used here is an open platform workbench that uses a hanger that is slightly longer than the height of the normal carrier, and is suspended on the traveling machine so that the traveling machine rolls on the normal rope. In addition, the traveling machine is equipped with an emergency tow line, which is different from the regular support line, to reach the intended rescue carrier. Since the hanger of this emergency carrier is formed in a retracted shape so as not to interfere with the regular carrier, it is possible to pass through the side of the regular carrier, or through the outside, thus, The workbench-type carrier is laterally attached to a side of the rescued carrier, and the passengers are transferred from the serviced carrier to the rescue. In addition, the traveling machine of this rescue carrier,
In addition to the structure that allows you to pass over the gripping machine of a regular carrier, the hanger is retracted so that it does not interfere with the regular carrier, as described above, The presence of another service carrier on the way does not cause an obstacle, and it is possible to get over or pass through this and reach the position of the next service carrier for rescue.

However, the prior art device thus formed has the advantage of being able to reach the position of the service carrier of the rescue target even if the service carrier of the service is present on the way. There are such restrictions on usage. That is,
As is well known, the props of the cableway are bearing-supported or pressure-supported by the pressure-receiving loop in the cableway line. However, since the traveling machine of the rescue carrier is designed to roll on the regular support line, it can pass over the receiving ring but roll under the pressure ring. The structure is impossible.

That is, FIG. 9 is an explanatory diagram showing the relationship between the receiving device 108a and the rescue carrier 130 in the prior art. The rope 104 is the receiving device 1 at the position of the column.
. 08a of the receiving ring 109a, 109a ... The common carrier 110 is a gripping machine 111 and the rope 1
04 will be operated. On the other hand, the rescue carrier 130
An open type cage 133 is suspended by a hanger 132 on a traveling machine 131 having traveling wheels 131a, 131a, and the traveling wheels 131a, 131a roll on the rope 104. In this configuration, when performing rescue work, the traveling wheels 131a and 131a are connected to the receiving device 108.
It is possible to pass along the rope 104 supported by the receiving rings 109a, 109a ...
Further, since it is possible to pass over the upper surface of the gripper 111 of the service carrier 110 that is in service, as long as the receiving devices 108a, 108a are used in the route on the way, up to the position of the service carrier 110 that is being rescued It is possible to reach and perform rescue work.

FIG. 10 is an explanatory diagram showing the relationship between the pressure cord device 108b and the rescue carrier 130 when the pressure cord device 108b is used.
The 8b pressure rings 109b, 109b ... Support the pressure lines. The rescue carrier 130 includes traveling wheels 131a, 13a.
Since 1a has a structure rolling on the rope 104, as is apparent from the drawing, in order to pass the position of the pressure cord device 108b, the traveling wheels 131a and 131a are connected to the pressure cord 109.
As shown by the arrow 134 between the b, 109b, ... And the rope 104, it is necessary to interrupt and pass, which is impossible. Depending on the unevenness of the terrain, a cable pulling device is often installed in the cableway, so
Therefore, there is a drawback that the area or range where the rescue is possible is extremely limited.

[0010]

SUMMARY OF THE INVENTION In order to solve such a problem, Japanese Patent Application Laid-Open No. 2-54535, “Rescue Device for Cableway”, which has been previously filed by the applicant of the present application, has been published. -53535 "Rescue device in cableway" and the like. Of these, the former is constructed by circulating a rescue rope with a drive device of a system different from this along the outside of the regular circulation path in the cableway equipment, and suspending a rescue carrier on it. Is. The rescue carrier is configured such that the rescue carrier main body can be moved up and down by a lifting means and a driving means along a hanger of the carriage suspended from a gripping machine. When going to the rescue operation, if the rescue carrier body is lowered to the lowered position, it is possible to reach through to the desired rescue carrier position without interfering with the regular carrier in the course along the way, Here, the rescue carrier body is raised to the same level as that of the rescued carrier device so as to be substantially side-by-side, and passengers are transferred to the rescue device to perform rescue.

In the latter case, the rescue rope provided with a drive device of a system different from that of the usual rope is also circulated along the outside of the circulation path of the ordinary rope in the cableway equipment, and the rescue rope is used for this purpose. The rescue carrier is configured by suspending the carrier, but the rescue carrier is obtained by suspending the rescue carrier main body through a telescopic hanger on a gripping machine. When the telescopic hanger is expanded and contracted by the driving means, the rescue carrier body can be moved up and down. When going to the rescue operation, lower the rescue carrier body to the lowered position, and even if there is a service carrier on the way, pass through it without interfering with it and reach the position of the required service carrier for rescue. It is possible to carry out rescue work by raising the level of the rescue carrier to a high level.

These prior arts have been able to be effectively used by eliminating the above-mentioned drawbacks, but further include the following improvements.

That is, in the above-mentioned device, the rescue rope is constructed so as to circulate in the outer region of the circulation path of the usual rope, and the strut arms supporting the rescue rope are supported in both outer directions. There is a problem in that the structure must be extended, the strut structure becomes large, and the width of the cableway line site becomes large. In addition, in order to make the levels of the rescue carrier and the rescue carrier coincide with each other, each rescue carrier must be provided with a lifting mechanism having a relatively complicated structure.

The present invention has been made for the purpose of providing a rescue device in a cableway facility which is improved so as to be used more economically without impairing the features or advantages of the rescue device proposed above. It is a thing.

[0015]

To solve this problem, the present invention relates to a cord stretched by being supported and guided by a column in a cableway line that is wound between pulleys at both ends, and the cord. In a cableway facility for transporting using a regular carrier suspended on a line, a rescue rope of a system different from the system of the rope is circulatorily stretched along the inner side of the circulation path of the rope. Suspend a rescue carrier, support the rescue rope by sharing the support column in a cableway line, and at a stop of the cableway equipment, a pulley that drives or tensions the rescue rope. In addition, the pulley is provided so as to be slidable back and forth so that the tension of the rescue rope can be adjusted. By adjusting the tension of the rescue rope, the rescue carrier and the rescue In cableway equipment that is designed to match the standard height of a standard carrier. Rescue device, which is constituted as.

[0016]

The rescue device of the present invention uses the rope that is wound between the pulleys at both ends and is supported and guided by the pillars in the cableway line, and the carrier that moves with the movement of the rope. It is used in cableway equipment for transportation by means of transportation. That is, a rescue rope is circulated and stretched in a region inside the circulation path of the usual rope, and a rescue carrier is suspended from the rescue rope. In addition, the rescue rope is driven or strained at the stops at both ends by using a driving device and a tensioning device of a system different from those used for the regular rope.

The drive device comprises a slide frame which is slidably movable back and forth, and a pulley on which a rescue rope is wound and driven. It is connected to a hydraulic cylinder for pushing or pulling the sliding frame. In addition, the tensioning device also includes a pulley that is tensioned by winding a rescue rope around the periphery on a sliding frame that is slidable back and forth. It is connected to a hydraulic cylinder for pressing or pulling the sliding frame.

When the regular cableway stops unnecessarily and a rescue operation is required, a staff member works on the emergency transporter with a wireless communication device, operates the rescue power unit, and operates the required rescue carrier. To reach. At this time, when the level of the rescue carrier is not the same as that of the rescue carrier, the sliding frame of the prime mover or tension device is slid forward or backward to stretch or loosen the rescue rope. . That is, when hydraulic oil is supplied to or discharged from a hydraulic cylinder connected to a prime mover or a tensioning device by a pump, the sliding frame and the pulleys provided on the sliding frame slide forward or backward,
Therefore, the rescue rope wrapped around the pulley is tensioned by being tensioned or is reduced in tension and relaxed. Therefore, if tension is applied, the level of the rescue carrier rises, and if the tension is reduced, the level of the rescue carrier rises. Therefore, it is possible to facilitate the transfer from the regular carrier to the emergency carrier and safely perform the rescue operation.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The rescue device for cableway equipment of the present invention can be applied to any of various types of cableway equipment. Here, it is applied to the single-line automatic circulation cableway that is most commonly used at present. I will describe the case.

It is closed. Alternatively, if necessary, a dedicated outlet may be provided.

In the overall arrangement as described above, the operation of the carriers 10, 10, ... In the common cableway equipment 1 is equivalent to the mode of operation of the carrier of a general single-track automatic circulation cableway. That is, one of the pulleys 3a and 3b, for example, the pulley 3a is a driving pulley having a drive device (not shown), and therefore the other pulley 3b is a tension device (not shown). In the case of a tension pulley including the above, the pulley 3 is rotated by the drive of the drive device, and the cord 4 is circulated accordingly. When the rope 10 is gripped by the gripping machine 11 at the stop 2a on one end side, the carrier 10 is pulled in the direction of the arrow 18 as the rope 4 travels and starts in the direction of the cableway line 5. In this way, in the cableway line 5, it operates along with the movement of the rope 4 supported by the receiving device 8a, the cording device 8b, etc., and when it reaches the stop 2b on the other end side, the gripping machine 11
The cord 4 releases the cord 4, and although not shown in the figure, the vehicle is turned back along the forwarding rail and the gripping machine 11 grips the cord 4 again and departs from the stop 2b on the other end side. When the rope 4 pulls the cableway 5 in the direction of the arrow 19 and reaches the stop 2a at one end, the rope 4 is released. In this way, the passengers are transported to the departure side again and repeat the same operation. In this figure, only two carriers 10, 10 are shown in order to avoid complications, but in reality, a plurality of or a plurality of carriers are used and they are operated one after another at predetermined intervals.

Next, the cableway equipment 21 for rescue will be described. As shown in FIGS. 1 and 2, at the stop 2a on the one end side, the pulley 2 is provided in the inner region of the circulation path of the above-mentioned regular rope 4.
3a is pivotally mounted, and in this case, the pulley 23a is the prime mover 4a.

On the other hand, on the sliding frame 43, the pulley 23a is rotatably mounted on a shaft 46 via a speed reducer 44. A drive device 45 is connected to the speed reducer 44, and the pulley 45 is driven by the drive device 45. 23a is rotated. As the drive device 45, a diesel engine or the like, or an electric motor or the like that is driven by using a power source of a system different from that of the usual cableway equipment is used, and the pulley 23a is rotated by the drive of the drive device 45. . Further, rollers 47, 47 ... Are pivotally attached to the sliding frame 43, engage with the guide rail 42, and are guided by the guide rail 42 to move back and forth. The protruding portion 43c at the end of 43 and the protruding portion 4 at the end of the guide rail 42 described above.
A hydraulic cylinder 48 is interposed between 2c and the cylinder 2c so that it can expand and contract. Also, the hydraulic cylinder 48 has hydraulic piping 49c.
A hydraulic pump 49 is connected via the above, and hydraulic oil is supplied or discharged.

Further, as shown in FIGS. 1 and 2, a pulley 23b is also pivotally installed in the inner region of the circulation path of the commonly used rope 4 at the stop 2b on the other end side. The pulley 23b is a tensioning device 50. The tensioning device 50 is a tensioning pulley, and the tensioning device 50 is configured to be slidable back and forth as needed. As shown in FIG. 8, the tension device 50 has a guide rail 52 fixedly mounted on an underframe 51 in a fixed position. On the other hand, sliding frame 5
A pulley 23b is rotatably pivoted on the shaft 3 by a shaft 56. The sliding frame 53 has rollers 57, 57 ...
Is engaged with the guide rail 52 and guided by the guide rail 52 to move back and forth. A hydraulic cylinder 58 is provided between the protruding portion 53c at the end of the sliding frame 53 and the protruding portion 52c at the end of the guide rail 52.
Is extensible. And hydraulic cylinder 58
Is connected to a hydraulic pump 59 via a hydraulic pipe 59c,
The hydraulic oil is supplied or discharged.

A rescue rope 24 is wound endlessly between the pulley 23a and the pulley 23b. In the cableway line 5, as shown in FIGS. 3 and 4, the rescue rope 24 is a rope receiving device 28a, 28a or a pressure rope device 28b, 28b provided on the lower portion of the pillar arm 7 or 7 of the pillars 6,6.
It is guided by the bearing or the cord. The rope receiving devices 28a, 28a for the rescue rope 24 and the pressure rope devices 28b, 28b are the rope receiving devices 8a, 8a or the pressure ropes 8a, 8a for the common rope 4 in the strut arm 7 or 7. It is fixedly provided in a region inside the cord devices 8b, 8b.

As shown in FIGS. 3 and 4, the rescue carrier 30 fixedly grips the rescue rope 24 by using a fixed gripping machine 31 to be connected thereto. The suspension machine 32 is suspended under the gripping machine 31, and a rescue cage 33 is further suspended under the suspension machine 32. The cage 33 has a waist 34 covered with an outer plate 35. The upper part shows the case of a semi-open basket-shaped carrier with the opening 36.
In addition, in the case of the present embodiment, two rescue vehicles 30, 30 are stopped at the stop 2a at one end and at the stop 2b at the other end, respectively, for a total of two vehicles, so that they can be operated in parallel. Done

Next, a rescue operation performed using the rescue cableway equipment as described above will be described. Regular cableway equipment 1
If for some reason it becomes impossible to drive, rescue work will be performed using the cableway equipment 21 for rescue. A staff member carries a radio for contacting the rescue carrier 30 so that he / she can board the rescue carrier. on the other hand,
A driving staff member operates the prime mover 40 of the stop 2a to rotate the drive device 45 to rotate the pulley 23a via the speed reducer 44 and the shaft 46, and thus the rescue rope 2
With the movement of 4, the rescue carriers 30 and 30 advance into the cableway line 5 from the stop 2a or 2b, respectively. In this way, when the rescue carrier 30 reaches the position of the rescue carrier 10 of the regular cableway equipment 1, the staff member onboard the rescue carrier 30 signals the operator of the prime mover 40 with the radio of the carrier. Stop the operation.

FIG. 3 shows a state in which the rescue carrier 10 and the rescue carrier 30 are stopped substantially horizontally at the position of the column 6 having the receiving devices 8a, 8a. Here, the staff member in the cage 33 is the carrier 10
After the exit 16 provided in the passenger car body 13 is opened, the passengers in the passenger car body 13 are transferred to the cage 33 and rescued. In the case of the present embodiment, the rescue carrier 30 has a capacity of one staff member and two or more passengers who are to be rescued. In this way, the passengers are transferred to the cage 33. When the work is completed, a staff member uses a radio to contact a staff member of the driving apparatus 40 to drive the driving apparatus 4
5 is operated in the reverse rotation to the case of the previous case, and is forwarded to the stop 2a to stop the passengers, and the rescue is completed. Alternatively, if necessary, the passengers who have been moved forward and rescued can be alighted at the stop 2b. When one rescue is completed, the same procedure is further repeated to perform the rescue operation of the other rescued carrier 10.

Further, FIG. 4 shows a state in which the rescue carrier 10 and the rescue carrier 30 are stopped substantially sideways at the position of the column 6 having the cording devices 8b, 8b.
In this case as well, the rescue procedure is exactly the same as the above case.

In both cases of FIGS. 3 and 4, the support column 6 or 6 is used.
The case where the rescue carrier 10 was stopped near the vehicle was explained, but in such a case, the regular cord 4 is used.
Is supported by or is supported by the receiving device 8a or the pressure device 8b, and the rescue cord 24 is also the receiving device 28.
Since it is supported by or is supported by the cable carrier a or the cable carrier 28b, there is almost no difference in height between the regular carrier 10 and the rescue carrier 30. However, when there is a carrier 10 to be rescued between the struts 6 and the middle of the struts 6, the flexures of the ropes 4 and the rescue ropes 24 do not necessarily match, and there is a difference in height between them. Is common.

In such a case, in the rescue device of the present invention, the rescue rope 24 is stretched or loosened so that the carrying heights of the rescue ropes are substantially the same and the rescue work is performed.
That is, the standard level of the rescue carrier 30 is the rescue carrier 10
If the level is higher than the standard level, the staff member on board the rescue carrier 30 communicates wirelessly to, for example, the stop 2
The tension of the rescue rope 24 is adjusted by operating the motor 40 of a. In FIG. 7, when the pump 49 is operated to discharge the hydraulic oil from the hydraulic cylinder 48, the telescopic rod 48c of the hydraulic cylinder 48 is shortened, and the sliding frame 43 is pulled through the protruding portion 43c to guide the guide roller. By guiding 47 and 47 to the guide rail 42, the sliding frame 43 slides in the direction of arrow 60. Therefore, the pulley 23a provided on the sliding frame 43 also moves in the direction of the arrow 60, and accordingly the rescue rope 24
Is relaxed, the flexure of the rescue rope 24 in the cableway line 5 is increased, and the level of the rescue carrier 30 is lowered. In this way, when the height of the rescue carrier 30 is approximately the same as the height of the rescue carrier 10, the operator of the stop 2a stops the relaxation of the rescue rope 24 by communication communication by the radio of the staff, and here Rescue work is performed.

On the contrary, when the level of the rescue carrier 30 is lower than the level of the rescue carrier 10, the rescue carrier 30 similarly communicates by communication, for example, at the stop. 2A is operated to tension the rescue rope 24. When the pump 49 of FIG. 8 is operated to supply hydraulic oil to the hydraulic cylinder 48,
The telescopic rod 48c of the hydraulic cylinder 48 extends and presses the sliding frame 43 via the protrusion 43c, the guide rollers 47, 47 are guided to the guide rail 42, and the sliding frame 43 slides in the direction of arrow 61. The pulley 23a moves dynamically, and thus the pulley 23a provided on the sliding frame 43 also moves in the direction of arrow 61. In this way, the tension of the rescue rope 24 is tensioned, the deflection of the rescue rope 24 in the cableway line 5 is reduced, and the level of the rescue carrier 30 is increased. In this way, when the height of the rescue carrier 30 substantially matches the height of the rescue carrier 10, the stop 2 based on the communication of the staff member.
The clerk of a stops the increase of tension of the rescue rope 24, and the rescue operation is performed there.

The above is a case where the rescue rope 24 is stretched and loosened using the motor 40 at the stop 2a, but if necessary, similarly, a tension device 50 provided at the stop 2b is used. It can also be performed using. The tensioning device 50 at the stop 2b is shown in FIG. As in the case described above, when the rescue rope 24 is loosened by wireless communication from the staff of the rescue carrier 30, the expansion rod 58c of the hydraulic cylinder 58 is shortened by operating the pump 59, and the sliding frame 53 is moved. Is pulled and slid in the direction of arrow 62. Therefore, the pulley 23b provided on the sliding frame 53 also moves in the direction of the arrow 62, whereby the tension of the rescue rope 24 is relieved, and the flexure of the rescue rope 24 in the cableway line 5 increases. , The level of the rescue carrier 30 is lowered. In this way, it is possible to perform rescue work by matching the standards of both carriers.

When the rescue rope 24 is strained, the telescopic rod 48c of the hydraulic cylinder 48 is extended by the operation of the pump 59 by wireless communication from the staff of the rescue carrier 30, and the sliding frame 43 is moved. Press and slide in the direction of arrow 63. Therefore, the pulley 23b provided on the sliding frame 43 moves in the direction of the arrow 63, the tension of the rescue rope 24 is tightened, and the flexure of the rescue rope 24 in the cableway line 5 becomes small, and The level of the carrier 30 rises. In this way, it is possible to perform rescue work while making the standards of both carriers substantially the same.

As described above, in the present embodiment, the case of being used for the automatic circulation type cableway has been exemplified, but the rescue device of the present invention is not limited to the case of the automatic circulation type cableway, and the crossing type cableway and other types. Needless to say, it is applicable to the cableway equipment of.

[0038]

As a rescue device in the case of an unscheduled stoppage of cableway equipment, various devices have been proposed up to now as an alternative to the emergency descender used for a long time, but many of them have been proposed. There is a drawback that it is not applicable to a circulation type cableway using a carrier or a rescue carrier cannot reach the position of the rescue carrier when the cable line is provided in the cableway line.

The rescue device in the cableway equipment of the present invention is stretched so as to circulate a rescue rope of a system different from the system of the service rope along the inner region of the circulation path of the serviceway equipment. In the cableway line, this rescue rope is commonly used to receive or pressure-support the pillars of the usual ropeway equipment, and at the stop, the rescue rope is placed in the area inside the usual rope. It is equipped with a pulley that drives or tensions. In addition, this pulley is slidably movable back and forth by a hydraulic cylinder so that the rescue rope can be tensioned or relieved so that the rescue carrier and the rescue carrier can be leveled. .

The device of the present invention solves the above-mentioned problems, requires only a small space for occupying a cableway for providing a rescue device, and has a compact and simple structure for the rescue carrier.
