Description

Technical Field

[0001] The present application relates to the technical field of steel structure welding, and in particular to a bridge steel structure welding device. Background Art

[0002] Bridge steel structure refers to a structural system constructed using steel in bridge construction. This structure usually includes the main supporting and load-bearing parts of the bridge, such as bridge beams, columns, cross beams, etc. Bridge steel structure has many advantages, including high strength, light weight, convenient construction, long life, etc., so it is widely used in bridge engineering.

[0003] At present, when installing I-shaped steel, most of them are lifted to the appropriate position by crane, and then welded manually. However, this welding method has great safety hazards and welding inaccuracy. That is, the I-shaped steel has no stable support point during the welding process, which is prone to deviation or shaking, which may lead to uneven welds or poor welding quality, and easily cause injuries to workers.

[0006] Preferably, the stable positioning mechanism includes a guide shaft fixedly connected to the inner side of the fixing frame, and the outer surface of the guide shaft is slidably connected to a slide plate. The stable positioning mechanism can stably support the I-shaped steel, thereby facilitating its safe and stable installation.

[0007] Preferably, a shift plate is fixedly connected to the top of the slide plate, a steel clamping plate is fixedly connected to the inner side of the shift plate, the inner surface of the steel clamping plate is movably clamped to the outer surface of the I-shaped steel, and the side of the steel clamping plate close to the steel beam still has a certain distance from the steel beam so as to provide a larger operating space for the I-shaped steel.

[0008] Preferably, a screw rod is threadedly sleeved on the inner surface of the fixing frame, and a knob is provided at the bottom of the screw rod.

[0009] Preferably, the top of the screw rod is rotatably connected to a shifting platform, and a lower through-shaft is fixedly provided on the inner side of the shifting platform.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The bridge steel structure welding equipment can ensure that the I-shaped steel remains relatively static during the welding process through a stable positioning mechanism, which helps to ensure the accuracy and consistency of welding work, avoid welding defects, improve welding quality, prevent structural deviation and asymmetry, and improve the stability of the entire bridge structure.

[0013] 2. The bridge steel structure welding equipment will not deviate or shake during the stable welding of I-shaped steel, which reduces the safety risks at the work site and improves safety.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-3 A bridge steel structure welding device includes a steel beam 1, a holding plate 2 is movably connected to the outer surface of the steel beam 1, a fixing frame 3 is fixedly connected to the outer surface of the holding plate 2, a fixing bolt 4 is arranged on the outer surface of the holding plate 2, and an I-shaped steel 9 is arranged above the fixing frame 3 through a stable clamping mechanism.

[0020] Through the above technical solution, the device can install the fixing frame 3 at the appropriate position of the steel beam 1 by using the fixing bolts 4 in conjunction with the clamping plate 2, and can make the I-shaped steel 9 in a stable state in conjunction with the stable clamping mechanism to facilitate accurate and safe welding thereof.

[0021] Specifically, the stable positioning mechanism includes a guide shaft 5 fixedly connected to the inner side of the fixing frame 3 , and a slide plate 6 is slidably connected to the outer surface of the guide shaft 5 .

[0022] Through the above technical solution, the two groups of guide shafts 5 are used to guide the two groups of slide plates 6 to move in opposite directions, thereby adjusting the position of the shift plate 7.

[0023] Specifically, the top of the slide plate 6 is fixedly connected with a displacement plate 7 , the inner side of the displacement plate 7 is fixedly connected with a clamping steel plate 8 , and the inner surface of the clamping steel plate 8 is movably clamped with the outer surface of the I-shaped steel 9 .

[0024] Through the above technical solution, the clamping plate 8 and the shifting plate 7 are able to stably clamp the I-shaped steel 9 as they approach each other.

[0025] Specifically, a screw rod 10 is threadedly sleeved on the inner surface of the fixing frame 3 , and a knob 11 is provided at the bottom of the screw rod 10 .

[0026] Through the above technical solution, the screw rod 10 will move along the vertical direction during the rotation of the fixing frame 3, thereby driving the shifting platform 12 at the top thereof to move synchronously.

[0027] Specifically, the top of the screw rod 10 is rotatably connected to a shifting platform 12 , and a downwardly penetrating shaft 13 is fixedly provided on the inner side of the shifting platform 12 .

[0028] Through the above technical solution, the shifting platform 12 is relatively limited by the two sets of swing bars 14 and will not rotate, but will only move up and down synchronously with the screw rod 10 .

[0029] Specifically, the outer surface of the lower through shaft 13 is rotatably connected with the swing bar 14 , and the inner side of the shift plate 7 is fixedly penetrated with an upper through shaft 15 , and the outer surface of the upper through shaft 15 is rotatably connected with the top of the swing bar 14 .

[0030] Through the above technical solution, the upper through shaft 15 cooperates with the lower through shaft 13 and the swing bar 14 to push and pull the two groups of shift plates 7, thereby achieving the effect of changing the position of the clamping steel plate 8.

[0031] Working principle: During the use of the device, before welding the I-shaped steel 9, it is necessary to first pass the fixing bolts 4 through the clamping plate 2 and fix it to the steel beam 1, so that the fixing frame 3 is stably installed in the appropriate position, and then the I-shaped steel 9 is hoisted by a crane until the I-shaped steel 9 is lifted between the two sets of clamping steel plates 8. Finally, the I-shaped steel 9 is stably supported by the stable clamping mechanism, that is, the rotating knob 11 drives the screw rod 10 to rotate. The screw rod 10 will move downward during the rotation process, and at the same time drive the shifting platform 12 connected to its top rotation to move downward synchronously. During the downward movement of the shifting platform 12, the swing bar 14 is pulled by the lower through shaft 13, so that the swing bar 14 rotates along the lower through shaft 13. During this process, the swing bar 1 The top of the two sets of shift plates 7 will rotate along the upper through shaft 15, and the shift plate 7 will be pulled by the upper through shaft 15, so that the slide plates 6 at the bottom ends of the two sets of shift plates 7 will slide along the guide shaft 5, that is, the two sets of shift plates 7 will approach each other until the clamping steel plates 8 inside the two sets of shift plates 7 will tightly clamp the I-shaped steel 9. At this time, the I-shaped steel 9 is in a stable state, which improves the safety when it is welded and installed on the steel beam 1, and will not cause deviation or shaking, reducing the safety risk at the work site, and ensuring that the I-shaped steel 9 remains relatively still during the welding process, which is conducive to the accuracy and consistency of the welding work, helps to avoid welding defects, improves the welding quality, prevents structural deviation and asymmetry, and improves the stability of the entire bridge structure.
