Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving device for a circulation type cableway.

[0002]

2. Description of the Related Art FIG. 5 is an explanatory perspective view showing a circulating cableway provided with a conventional receiving device. For a circulation type cableway, for example, a single-line fixed type special cableway (ski lift), a single towline 6 is wound between a pulley on the foot of the mountain (driving pulley) and a pulley on the top of the mountain (tension pulley). This is a cableway that circulates the transporter 2 fixed to the support cord 6 via the gripping device 4 and the suspension portion 3 by circulatingly driving the tow cord 6.

A plurality of struts 5 are arranged at predetermined intervals along the track (track) of the cableway, and the arm 51 of each stanchion 5 is provided with the cradle device 1A. The receiving device 1A is provided for the purpose of maintaining a predetermined position (for example, a height position) of the supporting cord 6 and smoothly passing the gripping device (grip) 4.

FIG. 6 shows a conventional receiving device (compression device) 1A.
It is a front view shown. The conventional receiving device 1A includes a bracket 73 provided at an end portion of a column arm 51, a beam 72 attached to the bracket 73, and a plurality of ropes (compression lines) rotatably supported by the beam 72. (Ring) 71.

Each of the cords 71 rotates in contact with the support cord 6 and guides the support cord 6. That is, the pressure ring 71 is always in contact with the support line 6, and it is important to affect various factors such as wear and damage of the support line 6, inertial force, and riding comfort.

[0006] Therefore, in the present pressure ring 71, a lightweight aluminum wheel core 71a lowers the rotational resistance to reduce the inertial force, and the outer peripheral groove portion 75 conforming to the diameter of the support cord 6 has a composite structure. By press-fitting the rubber liner 74 (see FIG. 5), it is possible to suppress abrasion damage of the towline 6 and improve riding comfort.

[0007]

PROBLEM TO BE SOLVED BY THE INVENTION Receiving device (pressure device)
From the viewpoint of smooth passage of the gripping device and protection of the towed lines, a limiting standard is set for the refraction angle per one impression ring and the burden load per one impression ring.

In order to comply with this legal standard, the conventional receiving device is designed so as to meet the load applied to the device and the refraction angle of the rope.
The receiving wheel is composed of two to eight wheels, and in many cases 16 wheels in combination with one column.

Further, each of these receiving loops is arranged in series with a predetermined gap therebetween. In other words, the adjacent ropes in which the rubber liner is press-fitted into the groove are arranged discontinuously with a constant gap.

Therefore, as shown in FIGS. 6 and 7, the head portion 4a of the gripping device (grip) 4 fixed to the support cord 6 is shown.
Collide with the bottoms of the groove portions 75 of the respective oppression wheels 71. Although this impact is somewhat mitigated by the rubber liner 74 press-fitted into the groove portion 75, the vibration impact generated at this time is extremely large due to the recent increase in the size of the cableway and the increase in operating speed.

Further, the gripping device (grip head 4a) is
As shown in FIG. 7, after colliding with the bottom of the groove 75, the groove 7
After being guided to the bottom of the orbit along 5, it returns to the original collision height position. At this time, the hanger (transporter 2) 31
Swings up and down in synchronization with the vertical movement of the grip head 4a.

[0012] As described above, in the conventional receiving device, the impact vibration and the vertical oscillation are repeated in a wavy manner as many as the number of the impression loops.
There was a disadvantage that gave passengers anxiety and distrust.

The present invention solves the above problems and reduces vibration when the gripping device passes through the receiving device,
It is an object of the present invention to provide a receivable device for a circulation type cableway which eliminates anxiety and discomfort given to passengers and has a good riding comfort.

[0014]

In order to achieve this object, the circulating type cableway receiving device of the present invention has the following structure. The reciprocating cableway receiving device is a receiving device that is attached to the arm of the column to maintain the rope at a predetermined position and smoothly pass the gripping device, and is an auxiliary device provided between the main pulley and the main pulley. It is characterized by comprising pulleys and one belt wound around each of these pulleys.

In the circulating ropeway receiving device having such a structure, the main pulleys arranged at the front and rear and a plurality of auxiliary pulleys arranged between the main pulleys are wound around each other by a single belt. It is set up.

With this structure, the belt is in contact with the towline, and the moving frictional force of the towline is transmitted to the pulleys via the belt to rotate. Therefore, the towline moves while being in full contact with the belt between the front and rear main pulleys (distance).

Then, the gripping device (grip head) fixed to the supporting cord passes through the receiving device while being in contact with the continuous belt. As a result, the head of the grip is the main pulley on the front side (the belt corresponding to the groove bottom of the main pulley).
Although a slight shock vibration is generated when it collides with, it then moves in contact with the endless belt which is tightly stretched.

Therefore, since the head of the grip does not collide with the groove of the rope until it passes through the main pulley on the rear side, no shock vibration is generated and a comfortable ride for passengers is realized. obtain.
