Problems solved by technology

For the large-scale spoke cable ferris wheel with a disc diameter of 110m that rides over the bridge to be built in the river, due to the limitation of the site conditions, a large crane cannot be used. Therefore, it is difficult to realize the installation and construction method of the conventional wheel disc. of

Embodiment

[0040] Taking the Ferris wheel installation of 110m in Tianjin Yongle Bridge as an example below, the installation and construction method of the present invention will be further described in detail.

[0041] The supporting frame of the ferris wheel in this embodiment is a herringbone door-type steel box frame. The height of the tower top from the standing water surface is 67m, and it rides on the banks on the upper and lower sides of the bridge. Connecting to the top of the herringbone tower is a main shaft with a diameter of 2.8m and a span of 21m. The wheel of the Ferris wheel is a turntable formed by tensioned radial steel cables and steel pipe truss tires, and is a flexible structure that rotates slowly around the horizontal main axis supported by herringbone steel towers on both sides. There is a raceway disc driven by the friction wheel on the outer ring. On the outer ring of the roulette, 48 sedan chairs that can carry 8 people are hung at equal distances.

Abstract

The invention discloses a towed rotary vertical section-to-section assembling construction system for a large-sized spoke type ferris wheel disc. An assembling construction method comprises the following steps: equally dividing a ferris wheel rim into a plurality of sector sections; mounting a lambdoid tower, connecting a rotary traction subsystem and a rotary vertical plane stabilizing subsystem in the assembly system, conveying a temporary support beam group to a position to be hoisted under a ferris wheel shaft, and vertically hoisting temporary support beams; mounting and folding each section of wheel rim by adopting a mode of unidirectional rotation of the wheel rim and section-to-section assembly, and mounting the temporary support beams and a spoke rope during the assembly of each section of wheel rim; preliminarily adjusting the wheel disc, namely tensioning each radial rope of the wheel disc twice to 50 percent; tensioning and adjusting radial ropes and tangential ropes to 70 percent so as to achieve the conversion of a structural system, adjusting the end and radial bounce of the wheel disc to accord with design requirement, and finally tensioning the radial ropes and the tangential ropes to 100 percent; and mounting a cage hanger and a drive roller way positioned on the periphery of the wheel disc.

Description

technical field [0001] The invention relates to a method for installing and constructing a wheel bridge, in particular to a system for installing and constructing a wheel disk of a large-scale spoke type ferris wheel. Background technique [0002] The main structure of the Ferris wheel (also known as the cable car) is generally composed of a supporting tower, a main shaft, a wheel, a cockpit, and a driving device. Discs can be divided into truss-type discs with rigid structures, spoke-beam discs, spoke-cable discs with flexible structures, and spoke-beam-cable hybrid discs. The diameter is generally 30-80m, and the diameter of large ferris wheel discs has reached 100-160m. . The existing installation method of large ferris wheel disc mainly contains integral horizontal assembly method, such as the famous "London Eye" Ferris wheel in Britain; the full truss type Ferris wheel can adopt the vertical installation method that rotates circle by circle from the center outward.
