Description

DETAILED DESCRIPTION OF THE INVENTION (a) Object of the Invention [Industrial Application Field] The present invention relates to a clamp device used for connecting a carriage and a cable mainly in a cooperative cableway in the field of a cableway. Things.

[Prior Art] A cableway is to transport a person or an object by suspending a carrier on a cable stretched between terminals at both ends and moving the carrier with the movement of the cable. This is well known. Broadly speaking, such cableways are classified into circular cableways and articulated cableways.

The circulating cableway is a cable that is connected to a gripping machine using a rope that is stretched and circulated endlessly between the terminals at both ends, so that the carriage is operated with the movement of the cable. There are an automatic circulating cableway that allows attachment and detachment of the cable and the carriage for each operation, and a fixed circulation cableway in which the carrier and the cable are semi-permanently fixed. The connection is made with a cable rig. In addition, the formal one has a relatively small carrying device, and a relatively small one corresponding to this is used for practical use.

On the other hand, a group referred to as an articulated rope is a group of stationary ropes that are stretched between terminals and ropes that are stretched and circulated between terminals. Using this and the two carriages suspended from the traveling machine, the traveling machine is guided by the support ropes, travels, and is towed by the towing ropes. It is designed to be operated alternately, and the carrier is generally large in capacity and large in number.

In the case of such an articulated cableway, a connection by a socket is generally used for connecting the towing cord and the traveling machine or the carrier.

FIG. 8 shows a configuration of the traveling machine 100 when such a socket-type connection is used.

A carrier (not shown) is suspended below a suspension machine 101, and the suspension machine 101 is swingably suspended on a main beam 103 of the traveling machine 100 by a pin 102. Main beam 1
03 is the beam 105,105 near the both ends via the pin 104,104
The beams 105 and 105 have pins 106 and 1 respectively.
Rollers 107, 107 and 107, 107 are pivotally mounted via 06 and 106, 106. Here, the rollers 107, 107 and 107, 107 are for rolling and guiding along the supporting cable 120.

The main beam 103 has a central portion extending downward, and a socket receiving member 108 is fixed to the main beam 103. Sockets 110, 110 are pivotally connected to both ends of the socket receiving member 108 via pins 109, 109, respectively. The socket 110,1
10 has a well-known conical hollow cylindrical shape, for example, inserts the cable end of the tow cord 121a from one side into the hollow space, untwists the cable end, and melts it. The above-mentioned babbit metal or white metal is cast and solidified and connected.
The cable ends are similarly inserted and fixedly connected.

With this configuration, the traveling machine 100 is indexed by the towing line 121a, and the rollers 107, 107, 107, 107 roll on the supporting line 120, and the operation of the transporter is performed.

Although such a connection with the tow cord and the equilibrium cord has the following drawbacks, it has been widely used as the most reliable one based on experience.

[Problems to be Solved by the Invention] However, a disadvantage of this apparatus is that the above-mentioned work of alloy welding requires troublesome techniques and experience,
This has to be done in the case of the cutting operation when the distraction occurs due to the aging of the cord. Recently, synthetic fiber cores from conventional hemp cores have been widely used as rocking oil cores for ropes, but when such socket connection is performed, synthetic fiber cores are used. This type of cord cannot be used because of the risk of burning or melting. In addition, in the vicinity of the socket insertion portion near the portion where the alloy has been welded of the socket, there is a place where it is easy to cause corrosion of the rope due to intrusion of rainwater and the like, and inspection is relatively difficult, and always requires attention. .

Further, since the connection by this device is semi-permanent solidification, for example, to correct the terminal stop position of the transporter,
There is a problem that it is not possible to cope with the case where it is desired to finely adjust the position of the carrying device with respect to the cable. Or, it could not respond to a request to temporarily release the connection between the cable and the carriage for some reason.

Correspondingly, in the ropeway, at one terminal, for example, a terminal at the foot of the mountain, a garage facility for accommodating two carriages is provided, and at the end of operation, at least one of the carriages is separated from the cable and the carriages are operated alternately. For the purpose of allowing both vehicles to enter the garage of one terminal, a clamp device using a link hydraulic device instead of a socket (for example, JP-A-62-88656) has been proposed. Since the connection is performed by strongly bending the cable, there has not yet been proposed a sufficiently satisfactory cable.

The present invention has been made in view of the above-mentioned circumstances, and the work is not troublesome as in the socket type. Therefore, the work is easy at the time of constructing the cableway, and also at the time of trimming the rope or updating the rope. Easy and easy inspection and fine-tuning when correcting the position of the carriage with respect to the cable.Even if there is a request to disconnect the cable from the cable due to any request It is intended to provide a stable and reliable semi-permanent connection between the cable and the carrier of the cable, and to provide a clamping device that does not cause damage to the cable. is there.

(B) Configuration of the Invention [Means for Solving the Problems] In response to this object, a clamp device for a cableway carrier according to the present invention includes a stationary cable stretched between terminals at both ends, and a terminal at both ends. An endlessly circulated running rope between the end and a traveling machine having a plurality of rollers to be rolled along the stationary rope, wherein the transporter is suspended via a suspension machine.

Next, a second embodiment of the present invention will be described. Third
FIG. 4D shows a case where the method of clamping the towing line 21 of the clamp device 30 is partially different. That is, the third
In the clamp device 30 shown in FIG. 3A, the pin 57 is disposed vertically above the towing line 21 when the towing line 21 is clamped, whereas in FIG. The lever is moved so that the center line 94 connecting the center of the pin 57 with the perpendicular 93 extending downward and the center of the tow cord 21 in the sandwiched state forms an angle θ.
The clamping member 54a and the clamping member 40a of the clamp body member 31 are formed. Other configurations are equivalent to the configuration of 30 of the clamp device described in the first embodiment.

[Operation] Also in the cableway equipment using the clamp device 30 of the present invention, a two-way support line is stretched as a stationary cable between terminals at both ends. The reciprocating line supports are each composed of one or two supports, and any of them can be adopted depending on the design requirements.However, in the description of this embodiment, the case where two supports 20 and 20 are used is shown. This is equivalent to the case of the conventional device.

Next, the tow cord as a moving cable is stretched between pulleys arranged at terminals at both ends, and spliced or rubbed to reciprocate the support cable, and endlessly reciprocate along a double track. Exceeded cyclable in direction. This point is different from the conventional device in that the towing line 121a and the balancing line 121b are endless with the pins 109 and 109 and the sockets 110 and 110 of the traveling machine 100 interposed therebetween, as shown in FIG.

Here, the towing line 21 used in the present embodiment is shown by circulating one strip endlessly.

The two rows of rollers 13, 13,..., 13, 13,... Of the traveling machine 1 are adapted to roll and be guided along the supporting ropes 20, 20, respectively. Are the main beam 4 via the roller beam 11 and the balance beam 9, respectively.
The load from the main beam 4 is evenly transmitted to the supports 20 and 20 in a balanced manner.

On the other hand, a suspension machine 2 is swingably attached to the main beam 4 via a central suspension pin 3, and a carrier (not shown) is suspended below the suspension machine 2.

Next, the main beam 4 of the traveling machine 1 is fixedly equipped with four clamp devices 30, 30, 30.

In this case, if one clamp device is described, the springs 90, 90 are respectively connected to the terminal members 85, 8 in the casings 80, 80.
The connecting beam 70 is pressed in the direction of the arrow 91 by pressing the large diameter portions 76, 76 from the preload state by the elastic force between the 5 and the large diameter portions 76, 76 of the rods 75, 75. The connecting beam 70 further indexes the connecting member 65 in the direction of arrow 91 via nuts 69, 69, and further pulls the vicinity of the upper end of the lever 50 in the direction of arrow 91 via pins 64, links 60, 60 and pin 63. .

Here, a clamping member 40 is provided at a horizontal position below the bracket portion 38 of the clamp body member 31, while the lever 50 is pivotally attached to the clamp body member 31 by a pin 57 and the clamping member 40 is located below the clamping member 40. Since the holding member 54 is provided at a position facing the member 40, if the tow cord 21 is positioned between the holding member 40 and the holding member 54, the upper part of the lever 50 can be pulled in the direction of arrow 91. As a result, the lever 50 rotates around the pin 57 in the direction of the arrow 92, and the groove 42 and the groove 55 firmly grip and grasp the towing line 21.

In this way, the other clamping devices 30, 30, 30, 30 also operate completely equally.

In this way, if the clamp devices 30, 30, 30, 30 are clamped at a desired position in the entire extension of the endless towing line 21, the clamp devices 30, 30, 30, 30 cooperate. And towing cord 21

Note that the tow cord holders 22 and 22 are hung so that the influence of the bending of the tow cord 21 in the cableway does not reach the vicinity of the ends of the holding members 40 and 54. The functions are equivalent to those used.

The present device is capable of semi-permanently and stably connecting the carrier and the towing line by firmly holding and grasping the towing line 21 in this way, but if it is necessary to disconnect the connection, a hydraulic device Jig or tool using the connecting beam 70 or lever
If the upper part 50 is pressed against the elastic force of the springs 90 in the direction opposite to the arrow 91, the holding members 40, 54 are opened, and the connection with the tow cord 21 can be easily separated.

In the second embodiment, the pin 57
Of the lever 50 so that a vertical line 93 passing through the center of the cable 50 and a center line connecting the center of the towing line 21 and the center of the pin 57 form an angle θ.
a, and the holding member 40a of the clamp body member 31 is formed, so that when releasing the holding state of the towing line 21 and releasing the towing line 21 downward, the holding member 54a is rotated in the direction opposite to the arrow 92. In this case, there is an advantage that escape and opening of the towing line 21 below are facilitated.

(C) Effects of the Invention The effects of the clamp device for a cableway carrier traveling machine according to the present invention having the above-described structure will be described below.

Conventionally, socket devices that have been commonly used include (1)
There are drawbacks in that the socket work is troublesome and (2) the connection or connection between the cable and the traveling machine is rigid and inflexible.

That is, with respect to the above point (1), appropriate skills and experience are required in performing the socket work, and it is necessary to perform the work under meticulous work management, and the work is troublesome. However, there is a drawback that a wire using synthetic fiber as an oil-impregnated core material cannot be used because heat is applied to the wire.

Regarding the point (2), as shown in FIG. 8, in the case of the conventional socket type, the socket, the pin, Socket receiving members etc. are interposed in series,
Since the cable system and the traveling machine system are not independent, there is no flexibility in the mutual relationship.

For this reason, when the rope is elongated after running for a long time and cut off, the above-mentioned socket work must be redone, and it is easy to correct the mutual position of the two carriages with respect to the rope. It was not possible to make fine adjustments or to remove one or both of the two carriers from the cable for some reason.

However, in the device of the present invention, in regard to the above point (1), by compressing or understanding the spring with a jig using a hydraulic device or the like, it is easy to pinch or release the towing, and Is easy. In addition, since there is no influence of heating on the strip by the socket alloy, any type of strip can be used.

Regarding the above point (2), the present apparatus is completely independent of the cable system and the traveling system, so that it is flexible, that is, the cutting operation corresponding to the elongation of the cable, the socket operation, and the socket operation. This can be dealt with only by processing the splice portion of the cable without the need for updating, and fine adjustment can be easily made even when it is desired to correct the position of the carriage with respect to the cable. In addition, it is possible to easily cope with a request to temporarily disconnect the carrier from the cable.

This also allows the convenience of the construction of the cableway equipment to be achieved, that is, it is possible to complete only the cable wrapping and overpassing work between the terminals at both ends completely independently of the traveling machine. After that, at the foot terminal, one traveling machine and a carrier are pinched and connected to the desired position of the cable, then this is sent to the summit terminal, and the other traveling machine and the carrier are also moved to the predetermined position of the cable at the foot terminal. The construction can be facilitated by pinching and connecting the cables.

In addition, in the case of a conventional socket-type device, in the vicinity of the socket, and in the case of the clamp type of the present device, in the vicinity of the clamp device, the rope is likely to cause fatigue due to repeated bending load. If the device is used, it is possible to perform safer cableway operation by moving and setting the traveling machine position to a rope location that has not passed such a history at every fixed cumulative number of aging operations. But,
Such a countermeasure cannot be made in the case of the conventional socket type.

In addition, this device requires the capacity of the spring to be used for the cableway, and can determine and adopt the optimum one by design, and can also increase or decrease the number of clamping devices to be equipped on the traveling machine. Thus, it is possible to provide a safe device having a rope holding or grasping force equal to or greater than that of the conventional socket type.
