Technical Field

[0001] The utility model relates to an assembly steel bridge welding tooling, belonging to the technical field of steel bridge welding. Background Technique

[0002] The assembled steel bridge has the characteristics of simple structure, light components, convenient transportation, flexible combination, rapid erection, convenient disassembly and assembly, and reusable components. At the same time, it has the advantages of large bearing capacity, strong structural rigidity and long fatigue life. It plays an important role in military transportation, disaster relief, national defense construction, water conservancy projects, road traffic and other fields at home and abroad and has been widely used.

[0003] The utility model with the patent number CN201420110564.6 discloses a large steel bridge deck. The steel bridge deck is welded by a plurality of steel bridge deck plates, the steel bridge deck plates are welded by two or more steel bridge deck units, each steel bridge deck unit is composed of several U-shaped ribs and a panel, several U-shaped ribs are welded on the panel at equal intervals, and the diaphragm connecting plate is welded with the U-shaped ribs and the panel.

[0004] The current technology has incomplete considerations and has the following disadvantages: when it is necessary to weld the adjacent first steel plate and the adjacent second steel plate together to form a large plate, if there is a problem of warping on the side of the second steel plate adjacent to the first steel plate, it is impossible to ensure the normal welding of the two steel plates without tools. This seriously affects the welding quality and reduces the welding efficiency.

[0005] To solve one of the above problems, there is an urgent need for an assembly steel bridge welding tooling. Content of the Utility Model

[0006] According to the above deficiencies in the prior art, the technical problem to be solved by the utility model is: how to utilize the downward pressure of the downward pressing component to solve the problem of warping of the second steel plate, and for this purpose, an assembly steel bridge welding tooling is provided.

[0007] The assembly steel bridge welding tooling described in the utility model includes a temporary welding base, and a hinge plate is vertically welded on the upper surface of the temporary welding base. It is characterized in that: it further includes a lever hinged to the hinge plate, a tail support seat is installed at the tail end of the lever, a downward pressing component is installed at the front end of the lever, a hinge seat is provided in the middle of the lever, and a hinge pin is detachably installed on the hinge seat, and the hinge pin passes through the hinge hole in the upper part of the hinge plate and is hinged to the hinge plate.

[0008] When it is necessary to weld the adjacent first steel plate and the adjacent second steel plate together, if the side of the second steel plate adjacent to the first steel plate has the problem of warping, it is impossible to ensure the normal welding of the two steel plates without tools. When using the tooling described in this application, it is necessary to first temporarily weld the temporary welding base to the first steel plate by using a welding machine, then connect the lever and the hinge plate by using a hinge seat and a hinge pin. At the same time, install a tail support seat at the tail of the lever and a downward pressing component at the front end of the lever. By using the downward pressure of the downward pressing component, the problem of warping of the second steel plate is solved, which is beneficial to the welding operation of the first steel plate and the adjacent second steel plate.

The upper end of the internally threaded tube penetrates through the lever and is welded to the lever. The upper end of the screw rod is vertically connected to a handle, and the bottom end of the screw rod is a pressing end. When the handle is rotated forward, the screw rod cooperates with the internally threaded tube to lower the height of the pressing end until the pressing end abuts against the second steel plate. By using the downward pressure of the downward pressing component, the problem of warping of the second steel plate is solved, which is beneficial to the welding operation of the first steel plate and the adjacent second steel plate. When the handle is rotated reversely, the screw rod cooperates with the internally threaded tube to raise the height of the pressing end and separate from the steel plate.

[0010] Preferably, the lever is of a plate-like structure, and a reinforcing rib plate A is welded on the upper surface of the lever along its length direction. The structural strength of the lever is enhanced.

The detachable connection between the lever and the tail support seat is realized, which is convenient for carrying or storing.

[0012] Preferably, a reinforcing rib plate B connected to the lever is arranged on the outer wall at the bottom of the internally threaded tube.

[0013] Preferably, two groups of downward pressing components are provided.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] For the prefabricated steel bridge welding tooling described in the present utility model, first, a temporary welding base is temporarily welded to the first steel plate using a welding machine. Then, a lever is connected to a hinge plate using a hinge seat and a hinge pin. Meanwhile, a tail support seat is installed at the tail of the lever, and a pressing component is installed at the front end of the lever. By using the downward pressure of the pressing component, the problem of the second steel plate warping is solved, which is beneficial for the welding operation between the first steel plate and the adjacent second steel plate. After the welding between the first steel plate and the adjacent second steel plate is initially completed, the temporary welding base can be knocked off from the first steel plate.

[0016] The prefabricated steel bridge welding tooling described in the present utility model saves manpower, material resources, and time during the welding operation process, and greatly improves production efficiency.

[0017] For the prefabricated steel bridge welding tooling described in the present utility model, when the handle is rotated forward, the screw rod cooperates with the internal thread tube to lower the height of the crimping end until the crimping end abuts against the second steel plate. By using the downward pressure of the pressing component, the problem of the second steel plate warping is solved, which is beneficial for the welding operation between the first steel plate and the adjacent second steel plate. When the handle is rotated backward, the screw rod cooperates with the internal thread tube to raise the height of the crimping end to disengage from the steel plate.
