Wheel type adaptive supporting system and large-scale sightseeing big-wheel lift car

Abstract

The invention discloses a wheel type adaptive supporting system and a large-scale big-wheel vehicle lift car. The wheel type adaptive supporting system comprises a main wheel, a side wheel and a wheelrim. The wheel rim sleeves a to-be-supported object. The main wheel is arranged on the to-be-supported object relative to the inner side of the wheel rim, is in rolling contact fit with the inner side of the wheel rim and supports the to-be-supported object in the wheel rim in a self-rotating mode. The side wheel is arranged on the to-be-supported object and is in rolling contact fit with the outer side surface of the wheel rim. Compared with a traditional device, the wheel type system is more convenient, more reliable, lower in manufacturing cost and more suitable for the usage working condition of the lift car.

Description

technical field [0001] The invention relates to a slewing support technology, in particular to a slewing support technology for a car of a large sightseeing car. Background technique [0002] In recent years, with the improvement of people's living standards, people's desire for playgrounds and amusement equipment is also increasing day by day. As a landmark facility in amusement equipment, the Ferris wheel has always been favored by playgrounds and large squares. Compared with a series of high-speed and high-inertia amusement equipment such as roller coasters and large pendulums, the observation car has a series of advantages such as stability and comfort, high-level viewing, and a wide audience. [0003] Looking at the development history of China's amusement industry, in the 1980s, there were some observation cars in China, most of which were imported foreign equipment and their heights were mostly below 50 meters. In 2002, with the completion of China's first observati...

Problems solved by technology

[0009] However, the actual load is much smaller than the bearable load, so it is more than enough to use the slewing ring in this case.

Moreover, the cars of the ferris wheel have used two sets of slewing bearings. The diameter of a single slewing bearing is about 3.2 meters, and the redundancy of carrying capacity is too large, causing a lot of waste

[0010] (2) The manufacturing cost of the slewing bearing installation base is high

[0012] (3) The material of the inner and outer rings of the slewing ring is forging, which is costly

However, the blank size of forgings has a large margin, and the machining and cutting workload is relatively large, so its manufacturing cost is also high

Since the working load of the car slewing bearing is relatively small, it is too extravagant to still use alloy steel forgings to manufacture the inner and outer rings of the slewing bearing.
