Embodiment Construction

[0032] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0033] 1. During the processing of the lower ball joint, three prism connection kit installation holes are precisely processed on the edge of the ball joint, and the prism connection kit is installed inside. The three prism connection kits are arranged in an equilateral triangle on the circumference of the same radius. Make sure the prism is on the plumb line after installation.

[0034] 2. Roughly adjust the positioning framework of the lower ball joint in place according to the measurement points, control the installation accuracy of the elevation and plane position of the positioning framework within ±10mm, and weld the positioning framework and the bridge bearing embedded parts under the positioning framework firmly.

[0035] 3. Hoist the lower ball joint to the positioning frame, install the locking device between the lower ball joint and the ...

Abstract

The invention belongs to the technical field of horizontal rotation construction for bridges, and particularly relates to a device and a method for accurately positioning a spherical hinge. The device and the method solve problems that repeated adjustment is required, the work efficiency is low, the accuracy is poor, and the like when a lower spherical hinge is positioned during horizontal rotation construction. The device for accurately positioning the spherical hinge comprises locking portions, fine adjustment tray sliding devices and a measuring portion. The measuring portion comprises three prisms, and the three prisms are mounted at the edge of the lower spherical hinge, are arranged along a plumb line, are mounted on the same radius circumference of the edge of the lower spherical hinge and are arranged to form an equilateral triangle. The method for accurately positioning the spherical hinge is implemented by the device for accurately positioning the spherical hinge. The device and the method have the advantages that fine adjustment operation is easy and convenient, and the spherical hinge can be accurately measured and adjusted and is high in positioning accuracy; and the spherical hinge can be quickly positioned, the positioning efficiency is high, the construction progress can be effectively accelerated, and the work efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of bridge horizontal swivel construction, and in particular relates to a precise positioning device and method for a spherical joint. Background technique [0002] At present, under special conditions such as crossing deep valleys, rapids, railways, and highways, the use of horizontal swivel technology is a common construction method for bridge superstructures, which has the advantages of not interfering with traffic and not interrupting traffic. In the swivel construction technology, the installation of the swivel device is one of the key processes, which has the difficulty of high control precision. At present, there are mainly two kinds of swivel devices used in China. The first one is a ring plane load-bearing swivel with tetrafluoroethylene as a slide plate, and the second is an axis supported by a spherical rotating shaft and supplemented by rollers (or moving jacks). Load bearing swivel. At pres...
