Description

[0002] In bridge engineering construction, shear pin welding is a key link of steel-concrete composite structure construction. Based on the existing technology, it is found that the traditional welding method mainly relies on manual positioning and operation, and there are problems such as insufficient welding gun posture control precision and shear pin skewing, resulting in poor welding quality consistency and large labor intensity of workers.

[0003] Especially prominent is that in the existing process, a porcelain ring is usually placed in advance on the surface of the bridge structure, and then the shear pin is inserted into the porcelain ring by manual operation.

The porcelain ring is a key component for ensuring the quality of weld formation, and the accuracy of its position is directly related to the welding effect. Once the porcelain ring is moved in construction, it will cause poor molten pool protection, irregular weld formation, and even defects such as loose shear pin welding and perpendicularity out-of-tolerance, which seriously affects the connection strength and durability of the structure.

[0045] After welding, the storage box 1211 needs to be moved up to separate from the shear nail 3, the upper electric sliding block 1202 is controlled to start moving up along the electric sliding rail 1201, so as to drive all the connected parts to move, so that the welding gun 204 moves up to reset, the lower electric sliding block 1202 is controlled to start moving up along the electric sliding rail 1201, the storage box 1211 is driven to move up by the lower electric sliding block 1202, so that the storage box 1211 moves up to separate from the shear nail 3, then the electric push rod in all the moving parts 11 is controlled to retract, so that the whole device is supported by the electric pulleys in the two moving parts 11, the electric pulleys are controlled to drive the whole device to move, after moving to the next welding position, the electric push rod in the moving part 11 is controlled to extend, so that the whole device is supported by the electric push rod in the moving part 11, the shear nail 3 is conveyed in the above same way, and the shear nail 3 is welded on the surface of the bridge structure.

[0046] In the further preferred embodiment of the present application, as shown in the accompanying drawings, Figure 12 The storage box 1211 is further provided with an electric clamp 301.

[0050] After the shear bolt 3 is broken, the external device pump machine is controlled to start operation to suck air, so that the negative pressure is generated in the conduit 302, the negative pressure is generated in the two suction pipes 303, the porcelain ring 4 fragments are sucked through the two suction pipes 303, the broken porcelain ring 4 is sucked and removed, the subsequent porcelain ring 4 cleaning process is further simplified, the overall work efficiency is improved, and when the shear bolt 3 is welded, harmful smoke is generated, at this time, the electromagnetic valve arranged in the suction pipe 303 is controlled to start operation, the passage in the suction pipe 303 is reduced, the external device pump machine is controlled to start operation to suck air, the harmful smoke is sucked through the two suction pipes 303, and the passage in the suction pipe 303 is reduced, so that the pressure of the suction pipe 303 is enhanced when the pump machine is operated under the rated power, thereby the harmful smoke diffused in the air is conveniently sucked.

[0051] As shown in the further preferred embodiment of the present application, Figure 5 The storage tank I 2 is hingedly connected with the upper cover 401, and the storage tank I 2 is fixedly connected with the gas conveying pipe 402.

[0052] In the embodiment, the pump machine for conveying gas is connected with the gas conveying pipe 402 in advance. After the shear pins 3 are installed in the storage tank I 2, the conveying pipe 210 and the storage tank II 211, the upper cover 401 is manually closed, so that the storage tank I 2 is in a closed state, and the electric actuator II 212 is controlled to drive the sliding plate 213 to move to close the circular hole 21101 of the storage tank II 211 which is not connected with the conveying pipe 210. Then, the hot gas can only flow out through the lower opening of the storage tank II 211. Then, the pump machine is controlled to start to convey hot gas into the gas conveying pipe 402. The hot gas enters the storage tank I 2 through the gas conveying pipe 402, and enters the storage tank II 211 through the conveying pipe 210. Finally, the hot gas flows out through the lower opening of the storage tank II 211 and blows to the surface of the bridge structure. In this process, the hot gas flows through all the shear pins 3, so that all the shear pins 3 are preheated. The hot gas blows to the surface of the bridge structure, so that the welding points on the surface of the bridge structure are preheated. Thus, most of the water and moisture on the surface of the welding area is effectively evaporated and dispersed. At the same time, the temperature difference between the welding seam and the bridge structure is reduced, so that the volume change gradient in the heating and cooling process is flattened, thereby effectively reducing the welding residual stress. It can be applied to different temperature environments.
