BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ropeway transport device.

0003

[Prior Art] When a gondola is transported by a ropeway transport device, the gondola separates from the main rope at both ends of the ropeway or at an intermediate station and passes through the boarding and alighting section at extremely low speed in order to allow passengers to board and alight. It is necessary to decelerate after leaving the main rope, and then accelerate after getting on and off until getting on the main rope.

Conventionally, in this acceleration/deceleration structure, rubber tires are arranged at short pitches on a gondola support part, and the rubber tires are accelerated/decelerated by bringing tire groups having different rotational speeds into contact with each other.

[0005]

[Problems to be Solved by the Invention] However, this method of driving the rubber tires by changing their rotational speeds one by one requires a complicated mechanism, and the rubber tires themselves wear out, so it requires considerable maintenance. It takes. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to obtain a ropeway transport device that has a simple structure and requires no maintenance. [Structure of the invention]

[0006]

[Means for Solving the Problems] The present invention provides a ropeway transport device for transporting gondolas, in which a reaction rail is provided at the bottom of the gondola, and a linear motor is arranged on the ground side of the terminal section facing the reaction rail. , is a ropeway transport device characterized in that the linear motor is inclined with respect to the moving direction of the gondola.

[0007]

[Function] Place the reaction plate of the secondary side of the linear motor on the gondola side, and place the primary side of the linear motor on the ground opposite this reaction plate to restrain the gondola from swinging sideways when running the gondola. By tilting the primary side of the linear motor at a predetermined angle to the right or left with respect to the direction of travel in this state, the force pushing the gondola in the direction of travel is reduced compared to when it is placed in the direction of travel. , the gondola is smoothly accelerated and decelerated, and it becomes possible to freely accelerate and decelerate continuously approaching gondolas without special control.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the ropeway transport device of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a ropeway gondola and ground equipment according to the present invention, FIG. 2 is an explanatory diagram showing the arrangement of linear motors for the acceleration section and deceleration section of the ropeway transport device of the present invention, and FIG. 3 is a ropeway at a turning station. It is a top view of a conveyance device.

First, FIG. 1 shows a cross section at the station.
A gondola main body 1 is supported by a fishing arm 2 with a fishing pin 3. In the ropeway section, the fishing arm 2 engages with the main rope with a wire grip 5 and hangs down, but in stations etc., it rides on the ground side rail 7 with wheels 4 and is generally hooked with a claw or hooked onto the fishing arm 2. The upper part of the vehicle is driven by rubber tires placed on the ground.

However, in the present invention, the gondola body 1
It has a reaction rail 11 and guide wheels 12 below, and moves while being guided by the guide wheels 12 on the left and right inside of the concave pit 9 of the boarding platform 8. This pit 9
A linear motor 10 is arranged at the center of the bottom at a position facing the reaction rail 11. The wire grip operating arm 6 has a ground rail 7 partially attached to the arm tip.
is arranged, and the wire grip 5 is opened by contact with the operating arm 6, allowing it to be separated from the main rope or suspended from the main rope.

Next, FIG. 2 shows the arrangement of the linear motor 10 in an acceleration section or a deceleration section. When the gondola main body 1 moves from the linear motor 10F toward the linear motor 10A in the figure, it becomes an acceleration section, and the opposite is a deceleration section. In other words, the linear motors 10A to 10D are a group of linear motors that are driven by a power source with the same pole pitch and the same frequency. Of these, linear motor 10A is driven in the same direction as the gondola traveling direction, while linear motor 10B is driven in the same direction as the gondola traveling direction. The linear motor 10C is tilted at an angle of θ1, and the linear motor 10C is tilted at an angle of θ2.
It is tilted by 3 degrees with respect to the direction of travel of the gondola.

Here, the linear motors 10E, 10F are as follows:
In a linear motor group where the pole pitch is short, the frequency is low, or both are small, the linear motor 10E faces the same direction as the gondola traveling direction, but the next linear motor 10F is arranged at a certain angle of inclination. has been done. Further, the number of linear motor groups increases as the speed increases.

Next, FIG. 3 is an explanatory diagram showing the arrangement of the main rope and the ground side rail of the gondola turn-around section, where the main rope 13 is connected to the drive wheel 1.
5, with the right side being the arrival side and the left side being the departure side. The main rope 13 is held in the air by a steel tower (not shown) beyond the pulley 14. A ground side rail 7 is provided from a place slightly outside this pulley 14, and section A is a deceleration section and section B is a deceleration section.
is a low constant speed section, section C is an acceleration section, and section D outside of it is a high constant speed section.

In addition to this, there is a structure in which a branching device is arranged in the low constant speed section B to retain the gondola, but this is omitted because it is not directly related to the present invention, but in the case of an actual structure, Of course it will be provided.

When the gondola main body 1 is grabbed by the wire grip 5 on the main rope 13A and enters the turning section, when the ground side rail 7 arranged on the ground side contacts the wire grip operating arm 6, the wire grip 5 loosens. Main rope 13
The wheel 4 comes off from A and transfers to the ground side rail 7, and enters the deceleration section A.

When the gondola passes over the linear motor 10A, which has a magnetic field movement speed v that is almost the same as the gondola speed at this time, and approaches the next linear motor 10B, the linear motor 1
0B has the same magnetic field moving speed v as the linear motor 10A, but since it is inclined by θ1 with respect to the moving path 16 of the gondola body 1, the speed is reduced to v cos θ when viewed from the gondola. Regarding linear motors 10C and 10D, the magnetic field movement speed is v cosθ for linear motor 10C.
2. In the linear motor 10D, as v cos θ3 and the inclination angle of the linear motor with respect to the gondola movement path increase, the apparent magnetic field movement speed of the linear motor decreases, and the gondola automatically decelerates.

Here, if the linear motor 10D is arranged inclined by θ3, the next linear motor 10E has a short pole pitch, a low power supply frequency, or a combination of both, so that the v cos θ3 of the linear motor 10D is The magnetic field movement speed v1 is configured to smoothly connect to the apparent magnetic field movement speed, and the linear motors 10A to 10
Similarly to D, the linear motors below 10F are also tilted, and the apparent magnetic field movement speed decreases.

When the linear motor is tilted with respect to the gondola movement path 16 in this way, v perpendicular to the direction of travel of the gondola is
A component force of sin θ is generated, and the gondola is pushed in one direction. This is counterbalanced by the guide wheel 12 being pressed against the side wall of the pit 9, and the force generated by this component becomes a loss and is dissipated as heat generated by the reaction rail 11.

Generally speaking, there is a 10 to 30 times difference in gondola speed between when the gondola is being transported on the main rope by the ropeway and when passengers are being boarded and disembarked at the terminal.
By preparing four to five types of linear motor pole pitches or power supply frequencies according to the present invention, it is possible to obtain a ropeway transport device having magnetic field movement speeds corresponding to the highest to lowest speeds.

On the other hand, considering the acceleration and deceleration of the gondola on the fishing arm 2 in the conventional terminal section, it is possible to make the rubber tires reach various speeds, like a device that presses and conveys rubber tires with different circumferential speeds. requires a complex drive system.

Furthermore, by forcibly driving the fishing arm 2 of the gondola by frictional force, maintenance was difficult due to wear of the tires and driven parts of the gondola arm, but according to the present invention, it is completely eliminated. Since it is a contact drive, it is easy to maintain, and it is possible to create all kinds of required speeds for the gondola using several types of linear motor sets, making it possible to simplify the entire device and eliminate maintenance, which cannot be achieved with conventional ropeway structures.

FIG. 4 is an explanatory diagram of another embodiment of the present invention. In FIG. 2, one linear motor is tilted in one direction, and the linear motors having different magnetic field movement speeds with respect to the direction of travel of the gondola are used. A component of force was generated in the direction perpendicular to the direction of travel of the gondola, but
In FIG. 4, when the linear motors 10G to 10N and 10G1 to 10N1 are arranged symmetrically with respect to the gondola movement path 16, the component forces in the left and right directions cancel each other out, and the gondola is pushed to either side by the component forces. This inconvenience is resolved.

As described above, according to the present invention, by preparing four to five types of combinations of pole pitch and drive power frequency, the speed change section from the main body of the ropeway to the terminal and back to the main body, and It becomes possible to drive gondolas that are 10 to 30 times different in travel speed in a constant speed travel section without contact. For this reason, the gondola drive device in the acceleration/deceleration section is simpler than before, and all drives are non-contact, making it possible to provide a ropeway transport device that has no wear parts and requires no maintenance. becomes.

As described above, according to the present invention, a reaction rail is provided at the lower part of the gondola, a linear motor is provided on the ground side of the terminal portion facing the reaction rail, and the linear motor is operated in the direction of movement of the gondola. Since the rope is inclined relative to the top, it is possible to obtain a ropeway transport device that has a simple structure and requires no maintenance.
