Ferris wheel

Abstract

The invention discloses a ferris wheel, comprising a ferris wheel bracket, a hollow round turntable, and a plurality of cabins and a plurality of turntable-connected traction steel cables which are circularly distributed outside the turntable, wherein column heads at two ends above the bracket are equipped with slewing bearings which are connectively integrated with a cross beam in the middle to serve as the center of the turntable, an outer ring of the slewing bearing is equipped with a steel cable disk, and two ends of all the traction steel cables are respectively connected with the steel cable disk and the turntable. Since the slewing bearing structure is adopted and inner rings of the slewing bearings are connected with the column heads and the cross beam, a flange face where the column heads are connected with the cross beam is only required to be processed so as to greatly diminish processing difficulty, and both the slewing bearings at two ends are fixedly connected, so the need of the structure of the current ferris wheel, in which the bearing at one end is fixedly installed while the bearing at the other end is flexibly installed, is not required, thereby simplifying the installation of the slewing bearings and remarkably reducing the technological requirement and the processing difficulty of entire equipment; thus the ferris wheel has reasonable structure, simple and convenient installation and low production cost.

Description

【Technical field】 [0001] The invention relates to a ferris wheel. 【Background technique】 [0002] As a ride for people to play, the Ferris wheel has become a landmark building in a city or a park. At this stage, the structure of the Ferris wheel is usually like this: it includes a hollow circular turntable, many cockpits around the turntable, and a rotating shaft located at the center of the turntable. The turntable is connected to the rotating shaft through trusses or steel cables. It is installed on the support of the Ferris wheel column through the bearings and bearing seats at both ends, such as figure 1 , 2 As shown, when working, the driving mechanism rubs against the turntable track (not shown in the figure) to drive the turntable to rotate, and realize the 360° rotation of the turntable around the rotating shaft 100 . It is required that the bearings 300 at both ends must be coaxial during installation, and the coaxiality of the positions where the bearings 300 ar...

AI Technical Summary

Problems solved by technology

At this stage, the structure of the ferris wheel determines that the coaxiality of the rotating shaft is high, and it is difficult to process the precision of the bearing installation position, and the production cost is high.

At the same time, in order to prevent the bearing from being stuck during the operation of the Ferris wheel at this stage, the general practice is to fix the bearing at one end and leave a gap for axial movement of the bearing at the other end. This requires that the column support of the Ferris wheel should have sufficient rigidity, and The installation process of the shaft is complex and difficult
