Abstract

PURPOSE:To generate appropriate frictional force and tractive force between a grip and a rope by using reaction obtained from the third track for the positional movement of a middle pin on a link mechanism constructed by two or more arms with pins on both ends to put the moving side grip in press contact with the fixed side grip via a rope at the middle. CONSTITUTION:A spring push plate 10 is connected to another pin on the second arm 14 so that the second arm 14 as well as the spring push plate 10 can move straight to the direction of a fixed grip around the pin. With the movement of a vehicle or equipment, the third track 6a inserted under a roller 15 lifts up the roller 15 and thereby a moving side grip moves to the direction of the fixed side grip 8, contacts a rope 4 and then obtains sufficient gripping force and tractive force by a rope gripping dish spring 12 compressed by reaction from the third track.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel rope railway pulled by a rope, an automatic circulation ropeway, etc. When the vehicle started to accelerate and accelerated, and reached the same speed as the line that was always running, the line was gripped, the driving force was obtained from the line, and the line traveled on a steep slope and approached the next station. At this time, it relates to a gripping machine attached to the underframe of a transportation system vehicle or transporter that releases a rope and enters the station yard by a method such as a chain, a belt, a side rope, a linear motor, or a self-propelled vehicle. is there.

[0002]

2. Description of the Related Art There is an automatic circulation cableway as a traffic system for traveling as described in the preceding paragraph. The rigging machine used for this is
The gripping spring is always compressed and gripped, and when released, the gripping spring is further compressed to open the grip. Also, using a link mechanism with dead points,
It is locked by a complicated mechanism that passes dead points with great force.

[0003]

The prior art has the following drawbacks. (A) Since the opening size of the grip is small, when the vehicle or the carrier swings while gripping, the cord may not be inserted into the grip. According to one example, the spring compression stroke for grip opening is 20 mm, the opening size of the grip is 56.5 mm when the cord diameter is φ45 mm, and the gap between the cord and the cord that should be a margin of the grip is 11.5 mm.
There is nothing. I want this gap to be at least 50 mm. (B) Similarly, since the opening size is small, the angle at which the grip wraps the cord is small, and therefore in a system in which the grip travels while lifting the cord, the cord may slip off the grip. (C) When the opening size is large, the force for gripping the cord is small, and therefore the traction force is small, which is not practical. (D) As the cord is used, it becomes thinner due to aging,
Although the gripping force is small, it was not possible to adjust this because of the structure of the conventional one. (E) The lock mechanism is complicated, and when locking,
In addition, it has been reported from the past that an accident that requires a large amount of force when unlocking, an accident that cannot be locked, a line stop due to an erroneous signal that it is not locked, and an accident that the lock cannot be unlocked.

[0004]

[Means for Solving the Problems]

(B) Inserting the third track (6a) under the roller (15) in FIG. 2, and inserting the third track (6b) over the roller (15) in FIG. By finding a new configuration in the machine, it is possible to obtain a sufficient opening size, a sufficient angle at which the grip wraps the cord, and a sufficient gripping force to grip the cord. (B) In FIG. 2, the thickness can be easily increased by laying a thin iron plate on the arm stopper plate (17), and when the movable side grip (9) grips the cord,
The distance between the spring pressing plate (10) and the fixed river grip (8) becomes small, and it is possible to cope with the thinning due to the aging change of the rope. In the conventional grip, such adjustment is impossible because the compressive force always acts on the spring. (C) In FIGS. 2 and 3, the first arm (13) and the second arm
The force for moving the pin up and down between the arm (14) and the arm (14) is 1/8 to 1/9 of the compressive force. By using such a weak force, it is easy to find a new structure for the lock mechanism. -Locks securely and can be unlocked.

[0005]

[Operation] In FIGS. 2 and 3, there are pins at both ends of the first arm (13). One pin is fixed to the rigging frame (7). The first arm (13) can rotate around this pin. First arm (13)
The second arm (14) is connected to the other pin of the first arm (13) and the first arm (13) and the second arm (14) can rotate around the intermediate pin. Second arm (1
The spring pressing plate (10) is connected to the other pin of 4), and the second arm (14) and the spring pressing plate (10) can rotate around this pin. However, the spring pressing plate (10) has a structure that linearly moves in the direction of the fixed grip, as shown in the figure. In FIG. 2, as the vehicle or the carrier moves, the third track (6a) inserted under the roller (15) lifts the roller (15), so that the movable grip (9) is fixed. )
The gripping disc spring (12) is compressed by the reaction force from the third orbit until the gripping cord spring (12) is moved to the direction (1) and comes into contact with the cord (4) to obtain sufficient gripping force / traction force. Since the moving amount of the movable side grip is not related to the spring coefficient of the gripping spring, a sufficient moving amount can be set. This makes it possible to obtain a sufficient opening size, a sufficient angle at which the grip wraps the cord, and a sufficient gripping force to grip the cord. Roller (1
When 5) is lifted by the third track (6a) and the arms (13) and (14) are crimped to the arm stopper plate (17), they are surely locked by the force of the gripping disc spring (12) as shown. It In FIG. 3, the third track (6) inserted on the roller (15) along with the movement of the vehicle or the carrier.
When the movable grip (9) is moved in the direction away from the fixed grip (8) by pushing down the roller (15) by b), the intermediate pin between the arms (13) and (14) causes the arm (13) to move. After passing through the straight lines of (14) and (14), the movable side grip (9) is retracted to a predetermined position due to the force released from the compressed state of the gripping belleville spring (12) and the self weight of the arm, and the rope is pulled. (4) falls and is released.
A weak spring may be used in order to more reliably retract the movable grip (9). There is also a method of fixing the handle to the first arm (13) in the vicinity of the pin on the side of the first arm (13) which is not the intermediate pin in order to move the intermediate pin up and down, and moving the tip of the handle by the third orbit. . Also, the first
In order to securely crimp the arm (13) and the second arm (14) to the arm stopper plate (17), a spring may be inserted into the vertical mechanism of the intermediate pin.

EXAMPLE An explanation will be given with reference to FIGS. 1, 2, and 3. The vehicle or carrier starts from the station. At this time, the driving force is provided by a chain, a belt, a side rope other than the rope (4), a linear motor, a built-in motor, or the like. The third track (6a) for gripping rope is installed at a point where the speed is the same as the speed of the rope (4) which is always driven, and the rail is lowered to the position where the rope is between the grips. Then, grab it by the above method, lock it by the above method, and run. Since it is a rope tow run, it can run on steep slopes that are not possible with other drive methods. The vehicle or carrier can start at short intervals of about 30 seconds. When approaching to the next station, the third track (6b) for cable laying is installed, and the line is laid down by the above method, and the vehicle or carrier travels with other power to enter the station and stop. The vehicle or carrier that arrives at the terminal station turns back, enters the down line at the point, and stops at each station while returning to the starting station.

[0007]

EFFECTS OF THE INVENTION By using the gripping device and the locking device that utilize the third track of the present invention, the conventional steel rope railway, which was only capable of making two round trips between two stations, can be operated at multiple stations. In the meantime, it will be transformed into a transportation system that departs from trains at short intervals and mass transportation, and it can be provided as an urban transportation system, not to mention mountains. The transportation system according to the present invention has a low construction cost and a driverless operation, so that the operation maintenance cost can be reduced.
