Description

[Detailed description of the invention] This invention is a double-track cableway winch that transports cargo by stretching a steel cable between the top and bottom of a mountain on a steep slope or in a mountain valley, and suspending a carrier from the steel cable. It is related to the device.

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 weight of the cableway 1 and the elongation due to tension, and consists of two static metal pulleys 4, 4 and one movable metal pulley 3 to which a counterweight 5 is attached. It is completed. The operation button switch 16 is attached to the main body of the cableway winch 6.

In the conventional cableway winch device having such a configuration, when the operation button switch 16 is turned off, the carrier 7 stops several seconds later. Therefore, in order to stop the carriers 17 fixed at appropriate intervals on the cableway 1 at the cableway base 18 for loading and unloading the transported cargo, the switch 16 must be turned OFF.
It is necessary to turn the switch on by estimating the distance that the switch will travel before it stops, that is, the stopping distance, and the stopping position varies depending on the operator operating the switch, which poses a problem in work efficiency. Furthermore, since the start switch is directly attached to the cableway winch, one of the workers must go to the cableway winch to press the start switch after the work is completed, resulting in a large time loss.

In view of these circumstances, the present invention uses a phototube switch to always keep the carrier 1 in the optimal position.
By installing a start switch on the work platform of the cableway base 18, the carrier 17 can be stopped immediately after work is completed.
This invention relates to a cableway winch device that is capable of starting.

The details of the present invention will be explained below based on FIGS. 2 to 4.

In these figures, the same members, portions, and components as shown in FIG. 1 are designated by the same reference numerals. 2 and 3 show a cableway winch device of the present invention, in which a capstan 2 driven by an electric motor has one end attached to a tow rope 1
a A plurality of cableways 1 are wound around the other end as a return cableway 1b. The last winding 1c of the plurality of windings of the cableway 1 is provided long and is wound around the tension adjustment wheel 11. As a result, the cableway of one turn 1c is 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 strut 14 is a diagonal member 22
It can be laid down by removing the pin 23.

The phototube switch 19, which is a stop switch,
It is installed near the cableway 1 ahead of the cableway base 18 by the stopping distance of the carrier 17..., so that the switch 19 is automatically turned off the moment the carrier 17 passes in front of the phototube switch 19. has been done.

Further, the start switch 21 is installed at an appropriate position on the workbench of the cableway base 18.

In addition, in FIG. 3, 17a is a real carrier, 17b is an empty carrier, 25 is a hanger rail, 26 is a presser supporter,
27 is the intermediate support, 8 is the grip, 29 is the passive vehicle,
30 is the anchor foundation.

Therefore, according to the above configuration, when the carriers 17... approach the cableway base 18, the phototube switch 19 installed in advance is automatically turned on.
It is turned OFF, and the carrier 17 always stops at the appropriate position on the work platform of the cableway base 18. When the work is completed, operation can be started immediately by simply turning on the start switch 21 provided on the workbench of the cableway base 18.

In addition, as shown in FIG. 4, a plurality of tension adjustment metal wheels 11 are provided in parallel and supported, and a freely rotating free wheel 2a is provided adjacent to the capstan 2.
After the cableway 1 wrapped around one side of the tension adjusting wheel 11 is wrapped around the free wheel 2a, the tension adjusting wheel 1 is wrapped around the free wheel 2a.
It is also possible to wrap it around the other side of 1 and then return to the other side. When doing so, the sliding width 15 can be shortened.

As explained above, the cableway winch 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 able to slide back and forth, a tension adjustment wheel rotatably supported by the clevis, a column erected behind the clevis, and a column provided at the lower end of the column. A first rolling wheel, a second rolling wheel provided at the upper end of the column, one end of which is locked and connected to the rear end locking part of the clevis, and the second rolling wheel is hooked around the second rolling wheel via the first rolling wheel. A cableway winch device comprises a cable and a counterweight suspended from the other end of the connecting cable, and the last turn of the cableway wound around the capstan is wound around the tension adjustment wheel. The balancing device is provided with a phototube switch that stops the capstan so that the cargo carrier stops on a work platform for loading and unloading cargo transported by the cableway, and also includes a phototube switch that stops the capstan when the capstan is stopped by the phototube switch. Since the starting switch for starting the cableway winch is provided on the workbench, the cableway winch can be operated from the cableway base 18, and unexpected accidents caused by the winch 6 can be avoided, resulting in safety. Furthermore, since the carriage is automatically stopped by the phototube switch 19, the stopping position of the carrier is always constant, allowing work to be carried out in the best possible condition and improving work efficiency. Furthermore, a skilled operator is not required to operate the carrier 17.
