Embodiment Construction
[0038] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0039] combine Figure 1 to Figure 4 As shown, a steel box girder butt detection assembly of the present invention is schematically shown, which is used for butt jointing of the first steel box girder 1 and the second steel box girder 2 . Wherein, the first steel box girder 1 has been erected, and the second steel box girder 2 is a bridge component to be docked (to be installed).
[0040] The steel box girder docking detection assembly includes a positioning frame 3 , an adjustment mechanism 4 , a light spot emitting device 5 and a light spot receiving device 6 .
[0041] like figure 2As shown, the positioning frame 3 includes a base 31 and a first positioning bracket ...

The invention relates to the field of bridge construction, in particular to a steel box girder butt-joint detection assembly. A positioning bracket and a light spot emitting device are both arranged on a first steel box girder; an adjusting mechanism and a light spot receiving device are both arranged on a second steel box girder; and a pushing device is used for being matched with the positioningbracket so as to finely adjust the relative positions of two steel box girders. The light spot emitting device can emit two crossed rays; the light spot receiving device detects the distance betweenthe two steel box girders according to light spots generated by the rays; the light spot emitting device can also detect the included angle of the two steel box girders on the horizontal plane throughthe rays; the operator of hoisting equipment can operate the hoisting equipment and the pushing device according to data detected by the light spot receiving device and the light spot emitting device, that is to say, in the butt joint stage of the steel box girder, manual observation of a safety worker or a commander is not needed, an operator can visually know the posture of the steel box girders in real time so that posture adjustment can be rapidly conducted, and existing hoisting precision and hoisting speed can be better broken through.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a steel box girder butt joint detection component and a butt joint method. Background technique [0002] Steel box girders, also known as steel plate box girders, are commonly used structural forms for long-span bridges. During the construction of such bridges, several sections of steel box girders need to be erected on bridge piers, and two adjacent steel box girders Splicing with each other, several sections of steel box girders form a complete bridge deck. [0003] At present, in the butt joint construction stage of steel box girders, engineering hoisting equipment is generally used to lift the steel box girders to be butt jointed, and a number of safety officers or commanders are arranged on the completed steel box girders to handle the jointing of the steel box girders. Observing the posture to direct the operator of the lifting equipment to operate correctly. Due to the...
