Description

Technical Field

[0001] The present invention belongs to the technical field of engineering construction equipment, and particularly relates to an auxiliary welding device and method for a heavy steel panel and a profiled steel stiffening beam. Background Art

[0002] Generally, heavy steel panels with a thickness of 18 inches or less are mainly designed to be used as flue wall panels or other equipment wall panels. However, large-area steel panels often have a certain degree of flexibility, resulting in a low surface flatness of the steel panel and being unable to support independently.

[0003] Due to the characteristics of large area, unevenness, and inability to support independently of the heavy steel panel, in the prior art, I-shaped steel is often welded on the back as a stiffening beam to improve strength and flatness. However, since both the steel panel and the stiffening beam are heavy steel materials, when welding directly, some parts cannot be closely fitted and cannot be adjusted. Forcing welding will result in different weld heights at each contact surface, thus affecting the construction quality. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary welding device and method for closely fitting a heavy steel panel and a profiled steel stiffening beam, so as to solve the problem that the heavy steel panel and the stiffening I-beam cannot be closely fitted and it is inconvenient to adjust the welding position during welding in the prior art.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] An auxiliary welding device for a heavy steel panel and a profiled steel stiffening beam includes a gantry fixedly arranged on the steel panel. The gantry includes a liftable crossbeam. A connecting piece is sleeved on the crossbeam. The lower end of the connecting piece is fixedly connected with a jack that presses vertically downward. The stiffening beam is arranged on the upper end surface of the steel panel and is pressed by the output end of the jack to press the steel panel and the stiffening beam to be closely fitted for welding operation;

[0007] The connecting piece includes a sleeve, a slideway opened on the side surface of the sleeve, and a plurality of backing plates arranged in the sleeve and below the crossbeam. Among them, the outer peripheral surface of the crossbeam and the sleeve are connected by right-angle fixing pieces and fastening bolts passing through adjacent right-angle fixing pieces.

[0008] As a further optimized scheme of the present invention, spherical supports are arranged on the right-angle fixing pieces inside the sleeve. A steel wire rope is arranged between the two spherical supports. And in the same plane, the steel wire ropes are cross-arranged and a limiting tube is sleeved at the intersection point.

[0009] As a further optimized scheme of the present invention, turnbuckles are arranged on the steel wire ropes.

[0010] As a further optimization scheme of the present invention, the cross-section of the stiffening beam is specifically in an I-shaped structure.

[0011] As a further optimization scheme of the present invention, the gantry is fixed to the steel panel by welding.

[0012] As a further optimization scheme of the present invention, a buckle is welded to the upper end surface of the steel panel, and the gantry is detachably arranged on the steel panel through the buckle.

[0013] As a further optimization scheme of the present invention, a spirit level placement plate is horizontally arranged outside the sleeve.

[0014] A method for auxiliary welding of a heavy steel panel and a profiled steel stiffening beam by using the auxiliary welding device described in any one of the above, the method comprising the following steps:

[0015] Step 1: According to the position where the stiffening beam and the steel panel are to be welded, fix the gantry on the upper surface of the steel panel so that the stiffening beam is directly below the gantry;

[0016] Step 2: Sleeve the sleeve on the cross beam, fix the jack base on the lower surface of the sleeve, and then adjust the position of the sleeve on the cross beam so that the jack is directly facing the stiffening beam;

[0017] Step 3: According to the height that the jack needs to press and the stroke distance of the jack, adjust the position of the cross beam in the sleeve in the vertical direction, and fix the sleeve through the right-angle fixing piece and the fastening bolt;

[0018] Step 4: Fill the space inside the sleeve and below the right-angle fixing piece with a backing plate;

[0019] Step 5: Start the jack to press the upper end of the stiffening beam, press the steel panel and the stiffening beam until they are closely fitted, and then perform the welding operation.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1) By setting a connecting piece between the cross beam of the gantry and the jack, compared with directly setting a fixing bolt in the slideway, a right-angle fixing piece is arranged between the inner walls of the connection between the cross beam and the sleeve in the present invention, and the right-angle fixing piece here can be made of an elastic material, so that by performing flexible pressurization on the right-angle fixing piece inside the fastening bolt, the rigid fixing of the pressurization of the fastening bolt is weakened, avoiding damage to the screw thread of the screw rod caused by rigid positioning of the fastening bolt, thereby achieving the effect of elastic fixing, so that the connecting piece in the present invention can be used for multiple auxiliary welding operations, improving the service life of multiple disassembly and assembly;

[0022] 2) In the present invention, the steel wire ropes are cross - arranged in the same plane, and a limiting tube is sleeved at the intersection point. Flower basket screws are provided on each steel wire rope. By adjusting the flower basket screws, the cross - arranged steel wire ropes are tightened to fix the right - angle fixing pieces, so that multiple right - angle fixing pieces and the fastening bolts connected thereto form a relative whole. Thus, during the process of the jack pressing the stiffened beam, the welding seam height error caused by eccentricity and shaking can be effectively prevented. Through the setting of the limiting tube, when the cross - arranged steel wire ropes form a cross - connection through the flower basket screws, the flower basket screws will not rotate under the limitation of the limiting tube, and the steel wire ropes can always remain in a taut state, thereby improving the stability of the overall connection within the casing.
