Description

[Detailed explanation of the invention] This invention is based on the idea of stretching a steel cable between the peak of a mountain with a strong slope and a mountain base, or between a valley between mountains.
This invention relates to a double-track cableway winch device that transports passengers or cargo by suspending a carrier from the steel cable.

FIG. 1 is a diagram showing a conventional cableway winch device. A cableway 1 is wound around the capstan 2 of the cableway winch 6, and the cableway 1 has a towing line 1a on one side and a return line 1b on the other side, and a tail force balance device 10 is provided on the return line 1b.

The power balance device 10 is a device for absorbing the elongation of the cableway 1 due to its own weight and the load of transported cargo.
It consists of two metal static pulleys 4, 4 and one metal movable pulley 3 to which a counterweight 5 is attached.

A conventional cableway winch device having such a configuration includes a cableway winch 6 and a tail force balance device 10.
Since it is a separate body, a large space is required, and the vertical movement distance of the movable pulley 3 needs to be about 8 m considering the extension and safety of the cableway 1 itself.
For this reason, the iron tower for fixing the static pulleys 4 and 4 is also at least 8
m or more was required, and the load applied to cableway 1 varies considerably depending on the material being transported and the amount of transport.
If the load is too large, there is a problem that the movable pulley 3 to which the counterweight 5 is attached rises too much and may come off, which is dangerous.

In view of the above-mentioned circumstances, the present invention integrates the cableway winch 6 and the tension holding device 10, thereby creating a safe cableway winch that does not take up much space and prevents the movable pulley 3 from coming off unexpectedly. A force balance device is provided.

The details of the present invention will be explained below with reference to FIGS. 2 and 3. In these figures, the same members, portions, and components as shown in FIG. 1 are designated by the same reference numerals. Second
Figures A and B show a cableway winch tail force balance device of the present invention, in which a plurality of cableways 1 are wound around a capstan 2 driven by an electric motor, with one end being a tow rope 1 and the other end being a return rope 1b. The last winding 1c or a plurality of windings of the cableway 1 having multiple windings is provided long, and it is connected to one or more tension adjusting metal wheels 11.
It is wrapped around. As a result, one or more turns of the cableway are wound around the capstan 2 and the tension adjustment wheel 11 in the form of an open belt.

The tension adjustment wheel 11 is rotatably supported by a clevis 12, and the clevis 12 is provided so as to be slidable back and forth within a certain range. That is, the structure is such that it does not move over a sliding width of 15 or more. On the other hand, a connecting cable 13 is stretched between the rear end locking part of the clevis 12 and the counterweight 5, and the connecting cable 13 connects the first rolling wheel 4a at a position on the lateral extension of the clevis 12, 2nd wheel 4
The struts 14 are connected via the struts 14 that each support the
A counterweight 5 is suspended from the second roller 4b at the upper end. The support column 14 can be laid down.

According to the above configuration, when the cableway 1 is stretched due to its own weight and the load of the transported materials, the tension of the entire cableway 1 decreases, and a difference occurs between the tensions at both ends of the clevis 12. As a result, the counterweight 5
By descending downward (in the R direction in the figure), the tension adjustment wheel 11 slides backward (in the P direction in the figure), so that the tension at both ends of the clevis 12 is always equal. Therefore, the tension of the cableway 1 is maintained constant regardless of the extension of the cableway. As shown in FIG. 3, a plurality of tension adjustment wheels 11 are provided in parallel and supported, and a freely rotatable free wheel 2a is provided adjacent to the capstan 2, so that the tension adjustment wheels 11 can be rotated freely. The cableway 1 wound around one side may be wound around the free wheel 2a and then wound around the other side of the tension adjustment wheel 11, and then the cableway 1 may be used as a return cable. When doing so, the sliding shaft 15 can be shortened.

As explained above, the cableway winch tail force balance device according to the present invention includes a capstan driven by an electric motor, a clevis provided at the rear of the capstan so as to be slidable back and forth, and a rotatably supported shaft on the clevis. a tension adjustment wheel, a post installed behind the clevis, a first wheel installed at the bottom end of this support, a second wheel installed at the top end of the support, and a locking wheel at the rear end of the clevis. A connecting cable having one end locked and connected to the capstan, the connecting cable being wound around the second rolling wheel via the first rolling wheel, and a counterweight suspended from the other end of the connecting cable, the connecting cable being wound around the capstan. Since the last turn of the cableway is wrapped around the tension adjustment wheel, installation of the device can be completed in a short time.
Maintenance and inspection are also easy. Furthermore, when moving the installation location, the entire device can be moved at once, making the work easier, and cost savings as there is no need to assemble the tension holding device each time as in the past.
