Description

The present invention relates to a prime mover of a rope-towed transportation facility that pulls a carrier by a rope to transport passengers and goods.

Passenger cars and trolleys (hereinafter collectively referred to as carriers) are towed by ropes to transport them. The rope-towed transportation equipment is a cable car that transports personnel as passenger equipment and transports goods as industrial equipment. It is known as an incline or the like. As a general configuration of a rope tow type transportation facility, a carrier is movably installed on a laid track, and a rope connected to the carrier is wound and driven by a pulley, so that the carrier is put on the track. It is configured to move along. In addition, a ropeway in which a support rope suspended in the air is used as a track and a carrier is towed by a rope along this track is also a type of rope tow type transportation equipment.

In such a rope tow type transportation facility, a prime mover for driving the rope is arranged at the stop on the mountaintop side, and the rope is wound around the prime mover provided in the prime mover to carry the carrier at both ends of the rope. A method is often adopted in which a carrier is connected to one end of a rope and a counterweight is connected to the other end to operate in a so-called pulley manner (see, for example, Patent Document 1). There is also a method in which the ropes are stretched in a loop between the stops and a carrier is connected to the ropes to operate (see, for example, Patent Document 2). The driving device includes a driving pulley around which a rope is wound, a speed reducer in which an output shaft is connected to the driving pulley, and an electric motor connected to an input shaft of the speed reducer. As the prime mover rotates, the cord wound around it is driven by the frictional force between it and the prime mover.

In this way, since the rope obtains a driving force by the frictional force with the driving pulley, it is necessary to increase the winding angle of the rope around the driving pulley depending on the specifications of the equipment. For this reason, conventionally, a plurality of pulleys are arranged in the stop, and the rope is wound around the prime mover multiple times through these pulleys to secure the required winding angle (for example, a patent). Reference 3).

However, if a plurality of pulleys are installed in this way, the equipment becomes expensive and the required space becomes large, which is uneconomical. The present invention has been made in view of such circumstances, and a rope that requires less space due to a simple configuration and can secure a large winding angle of the rope to the prime mover. It is intended to provide a prime mover for towed transport equipment.

In order to solve the above problems, the invention of claim 1 lays or suspends a track between stops, connects a pulley to a carrier traveling along the track, and provides the pulley at the stop. One of the ropes extending from the driving pulley in a rope towing type transportation facility in which the rope is wound around the driving pulley of the driving device and the driving pulley is rotationally driven so that the rope pulls and transports the carrier. A receiving deflection wheel that supports the strips from below, a pressure cord deflection ring that supports the other rope extending from the driving pulley from above, and a rope extending from the pressure cord deflection ring in front of the driving pulley. A first guide pulley around which a strip is wound and a second guide pulley around which a rope extended from the receiving deflection wheel is wound in front of the prime mover, and the prime mover is a track including the track. The rope is inclined in a direction orthogonal to the above, and is characterized in that the rope intersects left and right in a plan view between the receiving deflection wheel and the pressure rope deflection wheel and the driving pulley.

According to the present invention, the space required is small due to the simple configuration, and the winding angle of the cord to be wound around the driving pulley can be increased.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a vertical cross section of a track showing an example of a track of a rope towed inclined transportation facility, and FIG. 2 is a plan view of the track. As shown in the figure, the railroad track is formed by connecting the foothills stop 10 at a low altitude and the mountaintop stop 11 at a high altitude, and connects both stops 10 and 11 to form two rows. Two sets of tracks 12 are laid in parallel, and the ropes 13 are extended along the tracks 12. One end of the cord 13 is connected to a carrier 14a running on a set of tracks 12, the middle portion is wound around a prime mover 15 provided at the mountaintop stop 11 and folded back, and the other end is of another set. It is connected to the carrier 14b on the orbit 12. The carriers 14a and 14b connected to the rope 13 in this way move in opposite directions along the track 12 between the two stops 10 and 11 by driving the prime mover 15.

FIG. 3 is a front view of the prime mover, FIG. 4 is a side view of the prime mover, and FIG. 5 is a plan view of FIG. In the following description, the direction corresponding to the upper side in FIG. 5 is expressed as the right direction and the lower side is expressed as the left direction, and the direction corresponding to the right side in FIG. 5 is the front direction or the track side direction, and the left side is the rear direction. Express as.

First, the prime mover 15 is provided with a prime mover 24 that is driven by winding a cord 13. The driving pulley 24 is fixed to the output shaft of the speed reducer 25, and both the driving pulley 24 and the speed reducer 25 are tilted so that the right side is the lower side in the direction orthogonal to the railroad track. A shaft joint 26 is connected to the input shaft of the speed reducer 25, and the other end of the shaft joint 26 is connected to the electric motor 27. With this configuration, by driving the electric motor 27, the driving pulley 24 is rotationally driven in both clockwise and counterclockwise directions via the speed reducer 25.

A disc plate 31 is mounted on the input shaft of the speed reducer 25, and a disc brake 32 that sandwiches and brakes the disc plate 31 is provided. Further, a brake frame 30 is erected on the side of the prime pulley 24, and a pulley brake 33 that clamps and brakes the rim portion of the prime pulley 24 is mounted on the brake frame 30. The brakes 32 and 33 operate when the carriers 14a and 14b are stopped at the stops 10 and 11 or when an abnormality occurs during operation to stop the rotation of the prime pulley 24 or the movement of the rope 13.

A guide pulley frame 28 is fixedly installed in the track side direction of the prime mover 24, and the first guide pulley 20 and the second guide pulley 21 are rotatably supported on the left and right sides of the guide pulley frame 28. doing. Both the first guide pulley 20 and the second guide pulley 21 rotate in the horizontal direction, and the second guide pulley 21 is at a higher position than the first guide pulley 20. The cord 13 wound around the first induction pulley 20 is deflected inward from the track side toward the driving pulley 24 in a plan view, and extends so as to enter the left side of the driving pulley 24. Further, the cord 13 wound around the second induction pulley 21 is deflected inward from the track side toward the driving pulley 24 in a plan view, and extends so as to enter the right side of the driving pulley 24.

A deflection wheel frame 29 is erected on the drive pulley 24 side of the first guidance pulley 20 and the second guidance pulley 21, and the deflection wheel frame 29 includes a receiving deflection wheel 22 and a pressure line deflection wheel 23. Is rotatably supported in the vertical direction. The receiving deflection wheel 22 supports the cord 13 from below, whereby the cord 13 is deflected downward in the direction of the driving pulley 24 and extends. Further, the pressure cord deflection wheel 23 supports the cord 13 from above, whereby the cord 13 is deflected upward in the direction of the prime mover 24 and extends. In this way, the left and right cords 13 stretched between the first guide pulley 20 and the second guide pulley 21 and the prime mover 24 are vertically separated from each other at positions where they intersect each other in a plan view. They do not interfere with each other.

With the above configuration, when the angle θ at which the ropes 13 intersect in a plan view (see FIG. 5) is set to, for example, 90 °, the winding angle of the ropes 13 on the prime mover 24 is 270 °, and a large winding angle is secured. be able to. Therefore, even when the frictional force between the driving pulley 24 and the rope 13 increases and the tension difference between the left and right ropes 13 is large, the pulley 13 and the driving pulley 24 do not slide. The pulley 13 can be driven. In the above explanation, the cableway tow type transport facility in which the carriers 14a and 14b move along the track 12 laid on the ground has been described, but the carrier is operated along the support rope suspended in the air. The prime mover of the present invention can also be applied to a ropeway, a circulation type cableway in which a carrier is operated by a rope that circulates between stops, and the like.
