Description

[Detailed Description of the Invention] [Industrial field of application] The present invention facilitates the smooth release of the cords of the towed lines in the grips of the gripping device of the automatic circulation type cableway, especially the double type single line automatic circulation type cableway. The present invention relates to a sliding structure of a gripping device for moving.

[Prior Art] In an automatic circulation cableway, a towline is endlessly circulated between pulleys arranged at terminals at both ends (referred to as a stop. The same applies below), and a carrier is suspended. The gripping device is gripped by a towing line, and a carrying device is operated along with the circulation of the towing line to carry the carrier, which is often used for sightseeing in mountainous areas and transportation in ski resorts.

Conventionally, as the automatic circulation type cableway, a single-line automatic circulation type cableway which operates a passenger car type or a chair type carrier by using only one line of the towline has been generally used. A double-track single-line automatic circulation cableway has been proposed in which a relatively large passenger car is operated using a cable to increase the transportation capacity. There are mainly two types of double-type single-track automatic circulation type cableways that have been proposed so far.

FIG. 5 (a) shows a gripping device 101 provided in the center, and grips 103, 103 for gripping a towing cord (not shown) are extended outwards on both sides. 101
In the figure, one suspension device 106 is hung and a carrier 107 is suspended. Inside the terminal, the hanger 109,109 fixed to the fixed position 109a such as the ceiling beam of the terminal building
Thus, the rails 108, 108 are supported, and the guide rollers 105, 105 provided on the gripping machine 102 are guided to and transferred by the rails 108, 108. Such a method has been proposed, for example, in French Patent No. 2525981 "Ropeway with two towing cables", and since the gripping device 101 is located inside the two-row tow line, this term has not yet taken root. Although it is not, it is referred to as "internal formula" here for the sake of classification.

The one shown in FIG.
2 and 112 are provided on both sides, and grippers 113 and 113 for gripping a towline (not shown) are inwardly extended, and the grippers 112 and 112 are mutually connected by using a connecting member 114. In addition to being connected, the suspension machines 116, 116 for the left and right ones are suspended from the gripping machines 112, 112 to suspend the carrier 117. In the terminal, rails 118, 118 are supported by a hanger 119 fixed to a fixed position 119a such as a ceiling beam of the terminal building, and guide rollers 115, 115 provided to the grippers 112, 112 or the connecting member 114 are attached to the rails 118, 118. It is guided and rolls. This system has been proposed and proposed by the same applicant as that of the present application, for example, in Japanese Patent Application No. 62-295834 "Passenger Car Suspension Structure of Double Track Automatic Circulation Cableway and Gripping Device". In this method, since the gripping machine is located on both outer sides, it will be referred to as "external type" here.

In addition to this, there are known types in which a suspension machine is hung sideways, and these have their respective characteristics.

[Problems to be Solved by the Invention] Although the internal and external devices have their respective characteristics as described above, the following is common to both types when the gripping device grips or releases the device. There is a problem.

6 (a) and (a) show the gripping device in the case of the external type.
This shows the mutual relationship between the grippers 113 of the 111.
First, in FIG. 6 (A), the grips 113, 113 are opposed to each other, and the main parts of the gripping machines 112, 112 are located outside the grips 113, 113, respectively, but not shown. Here, the fixed grippers 113a, 113a and the movable grippers 113b, 113b cooperate with each other to grip the towing lines 120 or 120.

FIG. 6 (a) shows the appearance at the time of shooting. Here, the movable grippers 113b and 113b are opened as shown in the figure, and the towing lines 120 and 120 are ejected or released at positions 120 'and 120' (shown by chain lines) of the towing lines in the direct downward direction to perform the line release. Of.

However, the distance C between the tow lines 120, 120 is stretched to a constant value, and the distance between the grippers 113, 113 is also an arrangement distance that matches the distance C. When detaching the tow lines from the position 120 ', 120', the fixed gripper 1
The hook-shaped tip portions 113c and 113c of 13a and 113a are obstacles.
That is, at the time of release, the towing lines 120, 120 must be disengaged to the positions of the towing lines 120 ', 120' indicated by the chain line immediately below, but at the time of this detachment, the towing lines 120, 120 are fixed grippers. It is necessary to move over the tip portions 113c and 113c of the 113a and 113a.

Of course, the cord or the towing line is a flexible body, but since a certain amount of tension is applied to the towing line 120, 120, there is resistance to detachment, and the towing line 120 or 120 has the tip portion 113c. Or, it may be caught by 113c, resulting in poor shooting. Such a poor cable-laying is called "kneading", and it may run away without decelerating when it arrives at the carrier and may collide with a structure. It is an important matter to avoid.

The above description is for the case of releasing the rope, but also in the case of the grasping rope, similarly, the fixed grippers 113a and 113a are obstructed and the towing cords 120 and 120 are movable with the fixed grippers 113a and 113a. Handshake 11
The introduction between 3b and 113b is hindered, which may result in poor gripping.

Similarly, in the case of the above-mentioned internal formula, the same phenomenon occurs.

To deal with such a problem, Japanese Patent Application No. 63-67510 “Movable gripping device of a multi-branch automatic circulation type ropeway”, which is already filed by the same applicant as the present application, faces or faces the opposite direction. A movable gripping device has been proposed and its correspondence has been proposed, in which the first and second gripping devices are connected so as to be able to move closer to each other and farther away, and which is provided with a moving means for moving this closer and further away. .

In this technique, as an example of a moving means for moving the gripping device gripping portion toward and away from the gripping device, one that is controlled by a guide roller and a guide rail is shown.

However, although the basic constitutional action is disclosed by this technique, in order to realize this as the structure of the actual gripping device under the best conditions, there are restrictions on the arrangement position of the moving means and the purpose of the movement. Therefore, further development is desired in the point that the operation is most comfortable and the operation is smooth.

The present invention is based on the above-disclosed technology, and utilizing this, the sliding portion of the external double-type single-line automatic circulating gripping device that can be practically realized by performing the moving operation particularly smoothly. The purpose is to provide the structure.

[Means for Solving the Problems] To solve this problem, the present invention circulates the two strut cords in parallel at regular intervals and grips each of them from the outside. In a gripping device for use in an external double-type single-line automatic circulation cableway for suspending and transporting a carrier to the gripping device to be released, each gripping device has a sliding pin and one of the support cords. A single gripping machine using two unit gripping machines for common gripping, and another for gripping the other one of the above-mentioned tow cords in common with each other. The other gripping machine using the two unit gripping machines, and a slide hole for guiding the sliding pins of each of the unit gripping machines are provided. The unit and the rope are connected to each other so that the grips of the unit are located inside each other so that they can move closer and farther. And a guide in which the center of rotation is at a right angle to the axis of the sliding pin and at a right angle to the moving direction of the gripping device at the outer end of the sliding pin provided for each of the connecting member and the unit gripping machine. And a sliding means structure of a double-type single-line automatic circulation type gripping device using a moving means formed by pivotally mounting a roller.

[Operation] The sliding structure of the gripping device of the present invention is applied to the gripping device of the external double-type single-line automatic circulation type cableway.

A pair of spring-type unit rigging machines for gripping the two-row parallel towed lines are located on both outer sides of the towed lines and face each other. The grippers and the grippers are connected to each other by a connecting member so as to move closer to each other and move away from each other. The construction for moving closer and farther is such that the sliding pin fixed to the lower part of the unit gripping machine can slide in the sliding hole of the connecting member, and at the outer end side of the sliding pin. It has a guide roller horizontally.
Further, the sliding pin is provided with a spring, and the elastic force of the spring urges the unit gripping machines so that they are always positioned in mutually distant directions.

When releasing the gripping device, the grippers are opened by the usual method of compressing the main spring of each unit gripping device, which is a spring-type gripping device, and then the fixed guide rail. To press the guide roller. In this way, the unit grippers at the facing position move closer to each other in the facing direction, and the towing lines escape downward without interfering with the grippers.

In the case of gripping, the operation reverse to that in the case of releasing is performed.

At the lower end of the lever 51, a pin 53 is pivotally connected to a link 54, and the link 54 is pivotally connected to the end of the rod 54 by a pin 55.

The operation of such a spring-type gripping machine is as already disclosed in the above-mentioned publication, but basically, the main spring 48
The elastic restoring force pushes the rod 45 in the direction of the arrow 56a to rotate the movable grip 40 around the pin 39 in the direction of the arrow 57a via the pin 44, the link 42, and the pin 41 to grip the strut cord 10. On the other hand, when the roller 52 is released, when the roller 52 is pressed downward by using an external guide rail (not shown), the lever 51 rotates around the pin 50, and thus the pin 53, the link 54, The rod 45 is moved in the direction of arrow 56b via the pin 55. As a result, the main spring 48 is compressed by the step 46, and the rod 45 and the link 42 are further attracted. In this state, when the movable grip 40 is thrust from the outside, the pin 41 moves in the long hole 43, and the movable grip 40 pivots around the pin 39 in the direction of arrow 57b. It will be in the released state shown in a).

The above is a description of the configuration of an example of the spring-type gripping machine used in the present invention, but it is also possible to use various known spring-type gripping machines. Next, a part related to the sliding part structure of the gripping device characteristic of the present invention will be described.

A description will be given with reference to FIG. 2A together with FIG. 3A used for the above description. The frame 31 of the unit gripping machine 30 is shown in FIG.
As described above, the side walls 31a, 31a are formed on the left and right in the front view.
As shown in FIG. 3A, a bracket 61 is fixed between the side wall portions 31a, 31a and extends slightly downward, and a pin receiving portion 61a having a hole 62 is formed in the bracket 61. . The rear wall portion 33 of the frame 31 also extends slightly downward to form a bracket 63, and a pin receiving portion 63a having a hole 64 is formed in the bracket 63. The hole 62 and the hole 64 are coaxial with each other. It is located on the top and is perforated. A sliding pin 65 is inserted through the holes 62 and 64. As shown in FIG. 3 (A), the sliding pin 65 is a rod of equal diameter.
The neck portion 67 has a fork-like bifurcated shape via a step 66, and a guide roller 69 is horizontally pivotally attached to the neck portion 67 using a pin 68 to form the moving means 60. The sliding pin 65 is inserted into the holes 62 and 64 as described above, the step 66 is brought into contact with the pin receiving portion 63a, and the pin receiving portion 61a and the sliding pin 65 are, for example, locked. A fixing relationship is established by using the driving pin 73 and the like. In this way, the sliding pin 65 is integrally fixed to the frame 31 or the unit gripping machine 30.

Next, the sliding hole 65 of the connecting member 20 is externally fitted to the sliding pin 65 at the intermediate portion between the pin receiving portion 61a and the pin receiving portion 63a, and the connecting member 20 is attached to the sliding pin 65 with respect to the sliding pin 65. They are connected so that they can slide relative to each other. A spring 70 and a spring seat 71 are provided between the connecting member 20 of the sliding pin 65 and the pin receiving portion 63a.
Is extrapolated. The spring seat 71 is for maintaining the alignment of the spring 70. As assembled in this manner, the elastic force of the spring 70 causes the frame 31 to the unit gripping machine 30 to the connecting member 20.
Is always pulled toward arrow 72a.

Next, the operation of the sliding portion structure of the device of this embodiment will be described.

FIG. 4 shows the overall relationship in which the unit grippers 30, 30 of the gripping device 1 face each other. As described above, the unit gripping machines 30 and 30 in the figure are overlapped with the other unit gripping machines 30 and 30, respectively, but the movements are equally and jointly performed. Further, FIGS. 3 (A) and 3 (A) show the details of one unit gripping machine 30, of which FIG. 3 (A) shows that one unit gripping machine 30 is located on the left side of the figure. It has been moved to.

First, in FIG. 4, the unit grippers 30, 30 are opposed to each other and are connected by the connecting member 20 via the sliding pins 65, 65. Guide rollers 5, 5 are pivotally attached to the pins 5a, 5a, which are cantilevered to the connecting member 20, respectively. On the other hand, rails 7a, 7b are suspended and fixed at a fixed position, and the guide rollers 5, 5 roll on the rails 7a or 7b. In the rails 7a and 7b shown in this figure, one rail 7a is a groove rail and the other rail 7b is a flat rail. This is because if one guide roller 5 is guided by making one rail 7a a groove type, the course of the gripping device 1 can be determined without deviation, and the other guide roller 5 can be determined.
Is capable of following and rolling on the flat rail 7b.
Therefore, it is needless to say that both rails may be of groove type, if there is a particular need.

Next, the unit gripping machine 30, 30 shown in FIG.
As shown in (a), it is a spring-type gripping machine. The technique of the main body of the gripping machine of this type has already been disclosed and clarified as described above, and since it is not a direct feature of the present invention, its operation will be summarized. Since the book and the unit gripping machine 30 grip the tow cord 10 with the fixed grip 35 of the grip part 3 and the movable grip 40 by the elastic force of the main spring 48, when it is released. Is
Roller by guide rail (not shown) in fixed position
When 52 is pressed down, the main spring 48 is pressed and compressed through the lever 51, the link 54, and the rod 45, and the movable grip 40 is rotated to open the grip 3. 3 (a), (a) and FIG. 4 all show the grip portion 3 in an open state.

Next, the operation of the structure of the sliding portion of the device will be described.

In FIG. 3A, the grip portion 3 of the unit gripping machine 30 is in an open state by the above-described operation. It is externally fitted to the sliding pin 65 at an intermediate position between the bracket 61 or the pin receiving portion 61a extending downward from the frame 31 of the unit gripping machine 30 and the bracket 63 or the pin receiving portion 63a. The spring 70 is stretched by the elastic force, and in this state, the unit gripping machine 30 is positioned relatively to the connecting member 20 in the arrow 72a direction. The state of the relative position between the unit gripping machine 30 and the connecting member 20 is a fixed position in a free state in which the guide roller 69 of the sliding pin 65 is not pressed, that is, in a constant state. Further, in this state, even if the grip portion 3 is opened, the tip portion 35 of the fixed grip 35 is
Since the a is an obstacle, the towline 10 cannot smoothly escape directly below.

Next, as shown in FIG. 3 (a), along with the progress of the gripping device 1 or the unit gripping machine 30, a guide rail 80 for pressurization is provided in a section prepared in a fixed manner in the terminal (stop). When entering, the guide roller 69 is pressed by the guide rail 80 and rolls along the pressure. Therefore, the frame 31 to the unit gripping machine 30 together with the sliding pin 65 move in the direction of the arrow 72b relative to the connecting member 20, the spring 70 is compressed, and the space between the pin receiving portion 61a and the connecting member 20 is reduced. A gap 75 is formed in the gap. Along with this, the grip 3 is moved in the direction of the arrow 72b, so that the strut cord 10 in the released state does not interfere with the tip portion 35a and is not damaged, and the position of the strut cord 10 immediately below is 10 '.
You can escape to.

FIG. 4 shows the state shown in FIG. 3 (a) for the unit gripping machines 30 and 30 facing each other. That is, the guide rollers 69, 69 are pressed by the guide rails 80, 80 on both sides to roll, the sliding pins 65, 65 slide in the sliding holes 26, 26 of the connecting member 20, respectively, and the springs 70, 70. Are respectively compressed to form gaps 75, 75, and the unit rigging machines 30, 30 move closer to each other. Although the tow lines 10 and 10 are stretched at a predetermined interval from each other, due to the above-mentioned operation, the tips 35 of the fixed grippers 35 and 35 are no longer present.
a and 35a do not become obstacles and are located directly below the position of the towline 1
You can escape freely to 0 ', 10' without interference.

At the position where such a line-up operation is completed, the guide rail
It is a section where 80, 80 are not installed, and the spring 7
It may be freely restored to a position where it is balanced by distraction based on the elastic force of 0,70. Although the above description has been made for the case of straddling, when the gripping is performed, the support rails 10 and 10 are similarly used as described above by using the guide rails.
It is possible to introduce it into 3 and 3 without any interference, and to perform a smooth grab.

[Effects of the Invention] In the gripping device for a double-type single-line automatic circulation type cableway, it is always necessary to consider the fact that when striking or gripping the two-row tow lines, it must be performed without interference with the grip part. And

As a proposal for a solution to this, a configuration has been disclosed in which the gripping devices that compose the gripping device are slid toward each other and away from each other. However, there is a restriction on the arrangement position of the moving means for sliding near and far such as the functional portion of the gripping device, and in order to smoothly and smoothly perform the sliding movement. The composition has not been clarified yet.

The structure of the present invention, in particular, relates to the gripping device of the external double-type single-line automatic circulation type cableway, but as a moving means for approaching and distant sliding of the gripping machines, it slides in the hole of the connecting member. Since the pin is configured to slide and the guide roller for pressing this pin is provided on the outer end of the sliding pin and on the axis center line, it is effective for sliding when the guide rail presses the guide roller. Only thrust force acts,
Sliding operation is smooth and efficient.

Further, since the pressing of each of the gripping machines facing each other is simultaneously performed from both sides by the guide rails on both sides, the pressing forces of both are balanced with each other, and therefore the lateral pressure does not act on the entire gripping device or the carrier.

Further, for example, as is apparent from FIG. 4, since there are rollers, a pushing plate, etc. near the upper surface of the gripping machine, it is difficult to dispose this moving means. There are advantages and advantages such as eliminating the difficulty of such an arrangement design.
