BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable gripping device for a cableway traveling machine for connecting a tow line to a traveling machine on which a carrier is suspended, mainly in the field of cableways.

0002

[Prior Art] A transit cableway is a stationary cable stretched between terminals (hereinafter referred to as a stop) and a stationary cable stretched between the pulleys between the terminals. The traveling machine is towed by the tow rope using a circulating tow rope and two carriers with passenger cars suspended from the traveling machine, and the running wheels of the traveling machine roll on the support cables. , These two carriers are operated alternately between terminals, and these carriers are generally large-capacity passenger cars that can carry from several dozen to more than 100 passengers. . In the case of the above-described intersecting cableway, sockets have generally been used to connect the traveling machine and the towline.

FIG. 13 shows the structure of a carrier 100 using such a socket type connection. A passenger car (not shown) is suspended below a suspension machine 101. Further, the suspension machine 101 is pivotably connected to a main beam 104 of a traveling machine 103 by a suspension pin 102. Next, two wheel beams 106, 106 are pivotally attached to the main beam 104 at symmetrical positions on the left and right sides of both ends thereof at the central portion by beam pins 105, 105. Further, running wheels 108, 108 are rotatably connected to the two wheel beams 106, 106 by axles 107, 107, respectively. Further, a socket holder 109 is provided at the bottom of the main beam 104.
is fixed, and the socket 111 of the tow rope 121a is connected to one side via the connecting pin 110 so as to be able to swing up and down, and the socket 111 of the balance line 121b is similarly connected to the other side via the connecting pin 110 so as to be able to swing up and down. connected in a movable manner. Furthermore, when the carrier 100 travels, the sockets 111,
The cable support holder 112, 1 is installed to prevent the cable 111 from swinging suddenly.
12 is installed. In addition, the socket 111 described above,
111 has a conical hollow shape as is well known,
A tow rope 121a or a balance rope 121b is inserted from the short diameter portion, untwisted, and then molten Babbitt metal or white metal is cast into it to solidify and connect. As described above, although the method of securing the tow rope 121a and the balance rope 121b to the carrier 100 has the following problems, it has generally been widely used as the most reliable method of securing from experience.

0004

However, the above-described method of connecting and securing a tow line or balance line to a carrier requires skill and experience appropriate to casting Babbitt metal or white metal. When the tow rope or balance rope becomes stretched after years of use and needs to be trimmed, it is necessary to perform the same operation again. In addition, cables that use synthetic fiber as the oil-impregnated core material may not be used because the synthetic fiber core may burn out or melt. In the vicinity of the socket insertion part near the part where alloy welding of the socket has been performed, there are places where rainwater etc. can easily enter and cause corrosion of the cables, and where inspection is relatively difficult, so constant care is required. Furthermore, since this connection or anchoring method is a semi-permanent fixation, there is a problem in that it cannot be used at all when, for example, it is desired to finely adjust the position of the carrier relative to the cable in order to correct the terminal stop position of the carrier. . Furthermore, it has not been possible to respond to requests for special release of the connection between the cable and the carrier for some reason.

On the other hand, in the case of a transit ropeway, one terminal, for example, a terminal at the foot of a mountain, is provided with a station building that accommodates both transporters, and at the end of normal operation,
For the purpose of accommodating two carriers, at least one of which is separated from the cable and operated alternately, into one terminal station building, a clamping device using a link hydraulic system was developed in place of a socket connection method. 62-88656 "Multi-cable type ropeway" and JP-A-1-190574 "Clamp device for cableway carrier traveling machine" for spring type clamp device
Other methods have also been proposed for connecting and anchoring cables to carriers. The present invention does not require troublesome work unlike the anchoring method using sockets, and is easy to inspect.Also, even when the connection between the cable and the carrier is to be uncoupled due to some request, the work can be easily performed, and the cable can be easily The purpose of this design was to provide a method of anchoring the cables that has a stable and reliable connection with the carrier and that does not cause damage to the cables.

[0006]

[Means for Solving the Problems] Corresponding to this object, the rope gripping device for a cableway traveling machine of the present invention provides an endless connection between a support cable stretched between terminals at both ends and a pulley at the terminals at both ends. a tow rope that circulates in a circular pattern; and at least one traveling machine having running wheels and suspending a carrier, and a gripping device for connecting to the tow rope is attached to the traveling machine; In the cableway equipment that is towed by gripping the tow rope and transporting by rolling the running wheels guided by the support rope, the rope gripping device is connected to a support body on the side of the traveling machine body. , a plurality of clamp pieces that move toward and away from the tow rope and work together to grip and release the tow rope; and a clamp that moves the plurality of clamp pieces toward the center of the tow rope. a holder, an actuation ring rotatably inserted into the clamp holder, enclosing the plurality of clamp pieces, and having a wedge-shaped groove formed on an inner circumferential surface for abutting on the working surface of the clamp piece; A rotating means for rotating a ring to generate a gripping force on the clamp piece is incorporated into a support of the traveling machine main body, and the traveling machine can be connected to or released from the tow rope. Nasu.

[0007]

[Operation] The structure in which one or two stationary ropes are stretched between the terminals at both ends as a reciprocating track for the carriage to run is equivalent to the conventional method. Next, the towline as a movable rope is spliced or twisted between pulleys pivotally installed at the terminals at both ends so that it can be run endlessly in forward and reverse directions along the reciprocating track of the support rope. has been done. The present invention relates to a rope gripping device for connecting a tow rope to a traveling machine of a carrier, and this rope gripping device connects a plurality of clamp pieces that are movable toward the center of the tow rope so that they are concentric with the tow rope. They are guided by the clamp holder located above so that they are arranged evenly on the circumference of the towline in cross-section. Further, an actuation ring is rotatably inserted into the clamp holder. A wedge-shaped groove is formed in the inner circumferential surface of the actuating ring in the tangential direction at a position where the operating surface formed on the opposite side of the gripping surface of the clamp piece abuts. In this way,
When the actuation ring is rotated, the wedge-shaped groove also rotates, and the wedge-shaped groove surface slides tangentially on the working surface of the clamp piece, which is equally spaced on the cross-sectional circumference of the towline, and at the same time, the clamp piece also rotates. The gripping surface of the clamp piece moves toward the center of the tow rope and comes into contact with the tow rope. When the actuating ring is further rotated from this state, a component force is generated between the operating surface of the clamp piece that is in contact with the wedge-shaped groove surface and toward the center of the towline in response to this rotational force. This component force becomes the gripping force of the towline.

Next, the rotating means for applying rotational force to the actuating ring has hinge brackets fixed and extending at substantially symmetrical positions on the outer circumference of the actuating ring, and one hinge bracket is provided with a compressed disc spring. A pull rod that applies repulsive force to the tension side to provide rotational force is connected, and a push rod that applies the repulsive force of the compressed disc spring to the push side to provide rotational force is connected to the other hinge bracket. Eggplant. Further, adjustment bolts are provided so that the amount of compression of each disc spring described above can be changed. In this way, optimum gripping force of the towline can be obtained. Further, by making the above-mentioned clamp holder and actuating ring divisible in the circumferential direction, it is also possible to grip a tow rope which is twisted into an endless shape.

Effects of the Invention The effects of the gripping device of the present invention having the above-described structure will be described. In the conventional method of securing a towline to a traveling machine using a socket, the untwisting condition of the end of the cable, the cleaning of the untwisted part, the method of casting Babbitt metal or white metal, etc. must be adjusted accordingly during the socket work. It requires skill and experience, and in the case of mountainous areas, the work environment is harsh and it is difficult to make sufficient arrangements. Cables using synthetic fibers as an oil-impregnated core material cannot be used because they require labor and heat is applied to the cables. In addition, once the tow rope is tied to the traveling machine using the socket, it becomes a semi-permanent fixed relationship, and over time the tow rope becomes stretched and the weight used to tension the tow rope touches the floor. The towline must be trimmed and the socket operation described above must be performed again. Furthermore, when it is desired to finely adjust the relative positions of two carriers, socket work must be performed in the same manner, and although the reliability of the anchorage is high, there is a problem in that there is no flexibility in adjustment, inspection, etc.

The rope gripping device of the present invention is attached to the main beam of a traveling machine to fasten the towline to the traveling machine, and is attached to and separated from the towline in a cylindrical clamp holder to grip and release the rope. A combination of a plurality of clamp pieces for guiding the towline and a plurality of clamp guides for guiding the clamp pieces toward the center of the tow line is included. Further, an actuation ring for moving the above-mentioned clamp piece toward the center of the towline and for applying a gripping force to the towline is rotatably inserted into the clamp holder. A wedge-shaped gradient groove is formed on the inner peripheral surface of the actuating ring so as to be in contact with the clamp piece. In addition, a push rod and a pull rod are pivoted and extend parallel to the tangential direction of the outer circumference by sandwiching the actuation ring, and the compression of the disc spring applies a pushing force to the push rod and a pulling force to the pull rod, giving rotational force to the actuation link. is generated, and the direction of the force is changed to the pushing force of the clamp piece at the inclined groove part, which becomes the gripping force of the towline. In addition, if the compression of the disc spring is released, the acting force on the bush rod and pull rod disappears, and the actuating ring can be easily rotated in the opposite direction to the one used when gripping the rope, and the clamp piece has no gripping force and cannot be used to tow the rope. wander around In addition, the above-mentioned clamp holder and actuation ring have a structure that can be divided in the circumferential direction, so that the tow rope can be held even after the tow rope is connected in an endless manner, and the tow rope can be held on the traveling machine. can.

[0022] As described above, since the towline can be easily secured to the traveling machine using the rope gripping device of the present invention, the conventional socket work is no longer necessary, and only a splicing work is required. Also,
Since no heat is applied to the towline as in socket work, cables with an oil-impregnated core made of synthetic fiber can also be used as the towline. In addition, because the towline anchorage point, that is, the rope gripping point, can be easily changed, it is possible to move the gripping point after a certain cumulative number of trips and tow the rope in a place where there is no fatigue, resulting in safer operation. Ru. Furthermore, after each carrier arrives at the terminals at both ends, the tow rope of one carrier is released from the traveling machine, and only the other carrier is operated. It is also possible to accommodate it in a terminal.
