Description

This application claims priority of Chinese Patent Application No. 201910002222.X , titled "CABLE CAR AND CABLE CAR CURVE PASSING STRUCTURE", filed with the China National Intellectual Property Administration on January 2, 2019, which is incorporated herein by reference in its entirety.

FIELD

The present application relates to the technical field of cable cars, and in particular to a curve passing structure of a cable car. In addition, the present application further relates to a cable car including the curve passing structure of the cable car.

BACKGROUND

At present, a typical cable car is a secured style cable car with circulating cable holder, which performs both traction and load-bearing by a single moving steel cable. Since the steel cable needs to be pre-tensioned, a travelling line of the cable car is generally a straight line, and platforms are connected by a point-to-point manner. If a curve is to be set in the travelling line, a turning wheel needs to be set at the platform, and connection between a cable car body and the steel cable needs to be released by an unhooking device. The connection with the steel cable needs to be rebuilt through the unhooking device by speeding up after the cable car body slows down to have passengers get on and off at the platform, so the cable car body cannot pass continuously.
Therefore, a technical issue to be addressed presently by those skilled in the art is to realize a continuous passing of the cable car body on the curved line.

SUMMARY

In view of this, a curve passing structure of a cable car is provided according to the present application, which realizes a cable car body continuously passing on a curved line. A cable car including the curve passing structure of the cable car is further provided according to the present application, which realizes the cable car body continuously passing on a curved line.
In order to achieve the above objects, the following technical solutions are provided according to the present application.
A curve passing structure of a cable car includes a wheel, a curved steel rail line and a linear steel cable line extending outward from an end of the steel rail line. The wheel defines a wheel groove for installing the wheel on the steel cable line and is provided with a supporting flange for supporting the wheel on the steel rail line.
Preferably, a cable groove is provided on the steel rail line. A steel cable is provided in the cable groove and extends from an end of the cable groove and out of the steel rail line, and a part of the steel cable that extends out of the cable groove forms the steel cable line.

Preferably, the steel rail line is provided on a steel rail column.
A cable car includes a cable car body, and further includes the curve passing structure of the cable car according to any one of the above, and a wheel of the curve passing structure of the cable car is connected to the cable car body.
The curve passing structure of the cable car provided according to the present application, including the wheel, the curved steel rail line and the linear steel cable line extending outward from the end of the steel rail line, and the wheel defines the wheel groove for installing the wheel on the steel cable line and is provided with the supporting flange for supporting the wheel on the steel rail line.
In the curve passing structure of the cable car, an entire line includes the linear steel cable line and the curved steel rail line.
