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] Such as figure 2As shown, the positioning frame 3 includes a base 31 and a first positioning brack...

The invention relates to the field of bridge construction, in particular to a steel box girder docking detection assembly, the positioning bracket and the light spot emitting device are both arranged on the first steel box girder, and the adjustment mechanism and the light spot receiving device are both arranged on the second steel box girder. The pushing device is used to cooperate with the positioning bracket to fine-tune the relative position of the two steel box girders. The light spot emitting device can emit two intersecting rays, and the light spot receiving device detects the distance between the two steel box girders according to the light spots generated by the above rays. The light spot emitting device can also detect the angle between the two steel box girders on the horizontal plane through the above-mentioned rays, and the operator of the lifting equipment can operate the lifting equipment and the pushing device according to the data detected by the light spot receiving device and the light spot emitting device , that is, during the docking stage of the steel box girder, there is no need to rely on the manual observation of the safety officer or the commander, and the operator can intuitively and real-time know the attitude of the steel box girder, so as to quickly adjust the attitude, which is conducive to breaking through the existing hoisting accuracy and lifting speed.
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...
