Cableway tube three-dimensional coordinate controller and manufacturing method thereof

Abstract

The invention discloses a cableway pipe three-dimensional coordinate controller and a manufacturing method thereof. The controller comprises two flat-iron rings, an anchoring end positioning thin steel pipe, an extension end positioning thin steel pipe, a thin steel plate, multiple round steel hoops, six cableway pipe adjusting bolts, six round steel and multiple framework round steel. The cableway pipe three-dimensional coordinate controller provided by the invention can be used for solving the problem that the traditional cableway pipe is difficult to accurately position; and in the specific construction, the controller can be used for greatly reducing the measuring work as only standard parts need to be prepared, and can ensure the mounting precision. Moreover, for the cableway pipes of different lengths and different positions, only the controllers of different specifications are needed to be manufactured; and the controller utilizes less materials, is low in processing difficulty, and is widely applicable, easy to use and beneficial to site operation and use. Furthermore, the manufacturing method is simple and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of bridge construction auxiliary equipment, in particular to a cable-stayed bridge cableway pipe positioning device and a manufacturing method thereof. technical background [0002] With the rapid development of long-span bridges, the number of cable-stayed bridges continues to increase. The stay cable is the link connecting the main tower and the main girder on the cable-stayed bridge, and the cableway tube is an important component that anchors the two ends of the stay cable to the main tower and the main girder respectively. In order to prevent the cable from being damaged due to the friction between the cable and the nozzle of the cable pipe, and the additional bending moment caused by the eccentricity of the anchor point exceeding the design value, high requirements are placed on the position accuracy of the three-dimensional space coordinates of the center of the cable pipe. . In the past, the method...

AI Technical Summary

Problems solved by technology

However, when the length of the cable-stayed bridge is long, the towers are high, and the construction conditions are complex, the positioning and construction measurement of the cableway tube will be more difficult. As a result, the role of high-precision measuring instruments is often not fully utilized.
