Embodiment Construction
[0032] figure 1 A flowchart showing an embodiment of the present invention. refer to figure 1 As shown, a ferris wheel runner segment pre-assembly method, the Ferris wheel runner is spliced by N identical standard segments, and the pre-assembly method includes the following steps:
[0033] 101 making the N standard segments;
[0034] 102 Take out the n-th standard segment, the n+1-th standard segment and the n+2-th standard segment from the N standard segments and connect them end to end to form a pre-assembled segment;
[0035] 103 establish a three-dimensional coordinate system, and select a plurality of measurement points on the pre-assembled section;
[0036] 104 Measure the actual three-dimensional coordinate data of a plurality of said measurement points;
[0037] 105 grabbing the theoretical three-dimensional coordinate data of the measuring point in the 3D model of the Ferris wheel;
[0038] 106. Comparing the actual three-dimensional coordinate data of the meas...

The invention relates to a rotating wheel section pre-assembly method for a ferris wheel. A rotating wheel of the ferris wheel is formed by splicing N similar standard sections. The pre-assembly method comprises the following steps: manufacturing the N standard sections; selecting the nth standard section, the (n+1)th standard section and the (n+2)th standard section from the N standard sections, and connecting the selected standard sections end to end to form a pre-assembly section; establishing a three-dimensional coordinate system, and selecting a plurality of measurement points on the pre-assembly section; measuring actual three-dimensional coordinate data of the measurement points; capturing theoretical three-dimensional coordinate data of the measurement points in a 3D model of the rotating wheel of the ferris wheel; and comparing the actual three-dimensional coordinate data with the theoretical three-dimensional coordinate data of the measurement points, and if the pre-assembly section is out of size tolerance, adjusting the pre-assembly section according to the out-of-tolerance condition to eliminate the size tolerance. The pre-assembly method provided by the invention is convenient for structure manufacturing, section transportation and on-site mounting.
Description
technical field [0001] The invention relates to a method for installing and constructing a ferris wheel, in particular to a method for pre-assembling a large-scale ferris wheel. Background technique [0002] The diameter of the large Ferris wheel is larger than 100 meters, and the steel cable is usually used to fix the structure. During operation, the entire runner rotates around the horizontal axis, so the manufacturing accuracy of the runner, such as flatness and roundness, is very demanding. high. Considering that the project will be put into operation as soon as possible, the operator requires the runner to be manufactured in the workshop and installed on site at the same time, that is, the entire runner is required to be shipped and installed in batches. However, batch shipments may cause the runners to be unable to be pre-assembled as a whole. The batch shipment requires the runners to have certain interchangeability, which puts forward very high requirements for the...
