Spherical hinge positioning and mounting system based on three-dimensional laser scanning and application method thereof

Abstract

The invention belongs to the field of bridge construction, and particularly relates to a spherical hinge positioning and mounting system based on three-dimensional laser scanning and an application method thereof. The system comprises a control machine, a three-dimensional laser scanner, monitoring point prisms and a driving system, the monitoring point prisms are installed on all monitoring points, and the monitoring points are arranged on the surface of a spherical hinge positioning framework, the surface of a sliding way positioning framework, the surface of a spherical hinge sliding way and the surface of a bearing platform concrete of a swivel bridge. The system is applied to a spherical hinge mounting and adjusting construction process of the swivel bridge, and particularly relates to a mounting process of the spherical hinge sliding way and the spherical hinge positioning framework, and a three-dimensional laser scanning technology is introduced to replace traditional manual measurement and position adjustment, so that the measurement precision is improved, the labor cost is reduced, the construction efficiency is improved, and the adjusting effect is improved.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a three-dimensional laser scanning-based ball joint positioning installation system and an application method thereof. Background technique [0002] Swivel bridge construction is a construction method in which the bridge structure is poured or spliced ​​at a non-design axis position, and then put in place by swivel. This construction method converts the operation above the obstacle into the operation on the shore or near the ground. According to the rotation direction of the bridge structure, it can be divided into vertical rotation construction method, horizontal rotation construction method and the method of combining horizontal rotation and vertical rotation. , railways, highways, etc. The swivel system of the swivel bridge consists of a lower turntable, an upper turntable, a ball joint, a slideway, and a traction system. During the swivel process, a jack pulls ...

AI Technical Summary

Problems solved by technology

[0004] (1) More survey technicians and construction operators need to be invested, which increases the construction cost;

[0005] (2) Due to the large volume of related components and the large amount of data collected at the measuring points, it brings a large workload to the staff;

[0006] (3) Measuring technicians and construction operators need to restrict each other, and the waiting time for monitoring or adjustment is long, which further reduces the construction efficiency
