The cable receiving device 20 bends the cable 21 received by the pulley 22 and guide roller 23 to the crest side, the load A applied to the cable receiving device 20 is supported by the stretch frame 19, thus no neighboring stanchions are required.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of the installation of a cable receiving device at a cableway stop, and includes automatic circulation lifts, fixed circulation lifts, automatic circulation gondolas, and Bunshi-style gondolas. It can be applied to cableway equipment such as.

[Conventional technology]

Fig. 6 shows the arrangement relationship between the mountaintop-side stations 3 and 5, which are bent to the cable receiving device 6 of the nearest support post 2, as they face the mountaintop.
At the parking lot 1, which is headed toward the next second support column (not shown) at a slope of a certain angle θ, a turnback of the cable 5 or a motive pulley 7 is arranged, so that the tension of the cable 5 is transferred to the pulley 7. The load is supported by the pillars 9a, 9b of the station structure frame 8, and finally supported by the ground 11 via the station foundations 10a, 10b.

At the nearest strut 2, the load due to the cable tension based on the bending of the cable 5 at the cable receiving device 6 portion acts, so that the strut member 1
2. The base w13 needs to have a strong member and structure that can withstand it.

(What the invention attempts to solve! 1ull) The above-mentioned conventional technology has the following problems.

(a) Since the structure frame and cable receiver frame are separate, many pillar foundations and support foundations are required, which increases construction costs.

(b) It is necessary to monitor the mountain top side carrier (not shown) from the stop 1, but the column 2 prevents the view.

(c) The cable 5 is connected to the guide roller 14 and the support column 2 in the stop l.
It must be in contact with both of the cable receivers TL6 and fulfill the function of cable receivers, but since the berth 1 support column 2 is installed on different foundations and different structures, it may cause positional errors during construction. In this case, the cable 5 is easily detached from the guide roller 14 and the cable receiving device 6, which easily causes a problem.

(d) If either the berth base 1110 or the column foundation 13 sinks due to ground subsidence, the cable 5 will similarly shift in position with respect to the guide roller 5 and the cable receiving device 6, Safe operation of cable 5 cannot be ensured.

(e) The mountaintop stop 3 shown in FIG. 6 has the following problems in addition to the problems (a), (b), and (c) in the mountaintop stop described above.

If the ground shape at the exit of the bus stop falls at a steep angle, the ground height H of the vehicle departing from the bus stop 3 will be high, requiring a protective film 6i16 for safety, and a support 4 with a high overall height, which will increase the construction cost. It is dangerous because the transporter is operated at a high position.

(f) The installation locations of the nearest support column 2 in FIG. 5 and the nearest support column 4 in FIG. 6 are extremely restricted due to topographical conditions.

The cable bending section cable receiving device that was attached to the nearest column in front of the depot has been abolished, and an overhang frame has been installed protruding from the front part (on the cable side) of the structure frame of the depot, and the cable bending section has been installed on the overhang frame. Attach the rigging device.

If necessary, the structure frame of the bus stop can be moved up and down along the upright columns, and the angle of the mounting of the overhang frame can be adjusted.

[Effect]

Since the force acting on the cable bending section receiving device is received by the structural frame of the station, there is no need to strengthen the nearest column and its foundation. There is no need for a nearby support, which improves visibility and makes it easier to drive.

When operating a cableway in both summer and winter (snowy) seasons, it is necessary to adjust the height of the cable and the stops. The above-mentioned needs can be met if the structural frame of the stop is configured to be movable up and down.

If the height of the stop is changed, the freshness of the cable to the stop will change, so the angle of attachment of the overhang frame should be adjusted.

do. The rope receiving device TL20 is constituted by a rope receiving device with an equalizing frame or a fixed type rope receiving device that can obtain an equal Rm for each wheel.

In FIG. 2, an overhang frame 27 is installed protruding from the structure frame 25 of the C1 stop 24, and a cable receiving device 26 is installed on the same frame 27. 28 is a reinforcing frame provided on the overhang frame 27. The positions of the extension frame 27 and the cable receiving device 26 are determined so that the cable 29 can be reliably received by the guide roller 30 and the cable receiving ring 26a.

The depot is shown in FIG. 2, and in the front part (cableway side) of the structure frame 18 of the depot 17 in ζ in FIG. 20 is installed on the overhang frame 19.

In a fixed circulation cableway, a pulley 22, a guide roller 2
3, the cable 21 supported by the guide roller 23 is positioned so that the cable ring 20a on the side of the guide roller 23 of the cable receiving device 20 is horizontal, and the length between them is such that a passenger can get on and off the carrier. The rope receiving device 20 installed at the installation 19 bends the cable 21 received by the pulley 22 and the guide roller 23 toward the mountain top side.

A cable receiving ring 20 forming a cable receiving device 20 in which a reaction force A of the tension T1 of the cable 21 acts on the cable receiving device 20 by each bending rope.
The number of a is such that it can sufficiently withstand the reaction force A. The load A acting on the cable receiving device 20 is supported by the overhang frame 19, transmitted through the berth structure frame 18, and finally supported by the ground reaction force at the berth foundations 10a, 10b. Therefore, at the joint between the °C overhang frame 19 and the stop frame 18, there is a counterclockwise bending moment MA due to the reaction force A, and a clockwise bending moment M due to the weight W of the cable receiving device 20 and the overhang frame 19.
8 every time it works. When the cable 21 is installed and there is no tension, only the bending moment M acts, and each time the cable 21 is installed and tension is applied, the bending moment M1 acts.Therefore, the maximum Use strong members and structures that can withstand moments.

The overhang frames 19, 27, the rope support device 26 are designed to withstand the force generated by the weight W8 of the overhang frame 27, the rope support device 26, etc. The weight of the device 20.26 and
It can withstand the reaction force caused by the tension of the cable 21. Structure and weight of station structure frame 18.25 and foundation 10.29.

FIG. 3 shows an elevator stop 31, in which a stop structure frame 32 moves up and down along stop pillars 33. When the station structure frame is raised in the direction of arrow A, the cable 21 may be detached from the cable receiving device 34 like the cable 21a. In order to prevent the cables 21 from coming off, the overhang frame 35 is pivotally supported on the berth structure frame 32 by a pivot point 36, and the overhang frame 35. Cable receiving device 3
4 downward about the fulcrum 36, and
4 should not be separated from the cable 21a. The position of the overhang frame 35 is adjusted by a turnbuckle 37 provided between the support frame 38 installed on the stop structure frame 32 and the overhang frame 35.

FIG. 4 shows an embodiment similar to that shown in FIG. 1 in which a lower cable ring 20b is installed in the cable receiving device 20, and even when the cable 21 is displaced largely, it is possible to prevent the cable from slipping off. can.

Disengagement can be prevented by extending the structural frame of the station to the cableway side and attaching a cable receiving device that supports the cable by bending it upward or downward to the above-mentioned extended frame.

The last pillar (the pillar closest to the mountaintop stop) can be abolished, reducing construction costs.

(2) By abolishing the pillars closest to the stop, visibility from the cableway stop will be improved, ensuring safe transportation of passengers.

(3) After passengers get on the carrier, it is possible to prevent accidents such as contact with the nearest pillar due to the shaking of the carrier.

(4) Abolition of the pillar closest to the bus stop will increase flexibility in the location of the bus stop.
