Abstract

The invention provides a bridge chord member obstacle avoiding and line returning device and a using method thereof. The using method comprises the following steps of left side preliminary positioning, left side final positioning, left datum point determining, right side preliminary positioning, right side final positioning, right datum point determining and chord member top plate datum line drawing. The problems that an existing wire returning method and tool are not high in precision and complex and time-consuming in operation are solved. The line returning precision and efficiency are improved, and the line returning device can be flexibly suitable for line returning of various types of chord members; the device is reasonable in structure, light in self weight and convenient to use, hold and carry.

Description

technical field [0001] The invention belongs to the technical field of using methods of positioning tooling, and in particular relates to a bridge chord obstacle avoidance return line device and a using method thereof. Background technique [0002] In the process of assembling and positioning the chords of truss bridges, it is necessary to drill a group of connecting bolt holes at the end of the chord box mouth, and then connect the chords through splicing plates. Therefore, the relative position accuracy between the bolt hole groups at the end of the box mouth will directly affect the through-hole ratio of the connecting bolts when the rods are assembled, and then affect the stressed structure of the bridge; while the relative position accuracy of the bolt hole groups on the chord, It mainly depends on the marking accuracy of the operator's hole group. [0003] At present, most of the marking lines of the box mouth hole group of the chord are based on the box mouth end fac...
