Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an assembled welding platform for curved steel trusses. Background Art

[0002] With the strengthening of my country's economic strength and the needs of social development, new materials and technologies for building structures have a broader promotion and application platform; in order to meet people's higher requirements for the use function, novelty and fashion of building products, various large-span structures have emerged. The new large-span hyperbolic truss suspension structure is widely used in various large public buildings with its advantages of large space, material saving and novel structure.

[0003] For example: the “a hyperbolic cross-truss steel structure cooling tower” disclosed in the publication (announcement) number CN205840430U; for example: the “a steel truss beam structure for a curved bridge deck” disclosed in the publication (announcement) number CN109024267B; both are curved steel truss structures that are commonly used in the prior art.

[0004] The hyperbolic truss is a curved, special-shaped spatial structure, and its components are difficult to manufacture. The web members and chord members are connected by welding, and the upper and lower chords of the truss are spatial curves. When assembling and welding, component deformation is prone to occur, and the operation is inconvenient. It is also difficult to ensure the quality of assembly and welding during high-altitude operations.

[0005] Therefore, in order to solve the above problems, it is necessary to develop an assembly welding platform for curved steel trusses that has a reasonable structure and is easy to operate. Utility Model Content

[0006] The purpose of the utility model is to provide an assembled welding platform for curved steel trusses in view of the shortcomings of the prior art; the technical solution is as follows:

[0007] An assembled welding platform for a curved steel truss comprises a first connecting base and a second connecting base arranged in parallel; a plurality of vertical first columns are installed on the first connecting base, and a plurality of vertical second columns are installed on the second connecting base, wherein the first columns and the second columns are arranged correspondingly.

[0008] A plurality of connecting bottom rods are correspondingly installed between the first connecting base and the second connecting base, and a plurality of cross braces are correspondingly installed between the first column and the second column. The first connecting base, the second connecting base, the first column and the second column are installed as a whole through the connecting bottom rods and the cross braces.

[0009] The upper ends of the first column and the second column are also installed with slide steel plates, on which sliding platforms are arranged, and automatic welding equipment is correspondingly installed on the sliding platforms on both sides, and the sliding platforms can drive the automatic welding equipment to move on the slide steel plates accordingly.

[0010] The automatic welding equipment in the present device is an existing welding equipment, so the specific structure and specific operation mode of the automatic welding equipment are not described in detail. Those skilled in the art should be aware of the structural design and working principle of the automatic welding equipment.

[0011] Furthermore, the connecting bottom rod and the cross brace are both configured as lockable sleeve-type telescopic structures, so that the distance between the first column and the second column on both sides is adjustable.

[0012] The connecting bottom rod and the cross brace in the device can be set to a telescopic structure. In the prior art, there are many telescopic structures. The device is specifically designed as a sleeve-type telescopic structure with a locking function, so that the upper and lower adjustments are integrated.

[0013] Furthermore, slideways are provided at corresponding end faces of the first column and the second column, and sliders are provided in the slideways. The positions of the sliders are determined according to the heights of the curved steel trusses to be welded, and the sliders are fixed in the slideways by detachable fasteners.

Therefore, it is very important to fix the position of the middle curved steel truss. This device achieves fixation through a limiter.

[0017] Furthermore, the limiter is a "mouth"-shaped structure, which is correspondingly mounted on the cross brace. Fasteners are provided on both sides of the limiter, and the limiter can be fixed to the cross brace accordingly through the fasteners.

[0018] In the prior art, there are many options for limiters. In the present device, the limiter is specifically set to a "mouth"-shaped structure, similar to a square frame, which can be correspondingly mounted on the cross brace, and fasteners are set on both sides. After selecting the position, it is only necessary to tighten the fasteners on both sides to fix the limiter on the cross brace, thereby fixing the curved steel truss in the middle as a whole.

[0019] Furthermore, the first connecting base and the second connecting base are configured as box-shaped channel steel or square steel; and the cross brace is configured as I-beam or H-beam.

[0020] In this device, the first connecting base and the second connecting base need to correspond to the installation columns, so they can be set to box-shaped channel steel or square steel; and the cross brace needs to support the curved steel truss, and the two ends need to be installed in the slide of the column, so it is set to I-beam or H-beam. The overall structure is very reasonable and the structure is stable and reliable.

[0023] 2) The connecting bottom rod and the cross brace in the device can be set as a telescopic structure, which can be adjusted according to the specific size of the curved steel truss. The cross brace is installed in the grooves of the columns on both sides through the slider, so that the height of the cross brace can also be adjusted according to the specific size of the curved steel truss. The structure is reasonable, the overall structure is stable and reliable, and it can adapt to the welding of curved steel trusses of different sizes;

[0024] 3) In this device, a limiter is also provided on the cross brace. When the curved steel truss is placed in place, the position of the curved steel truss can be fixed by the limiter to ensure the welding quality and reduce the construction risk. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] like Figure 1As shown, an assembled welding platform for a curved steel truss includes a first connecting base 101 and a second connecting base 102 arranged in parallel; a plurality of vertical first columns 1 are installed on the first connecting base 101, and a plurality of vertical second columns 2 are installed on the second connecting base 102, and the first columns 1 and the second columns 2 are arranged correspondingly.

[0030] A plurality of connecting bottom rods 103 are correspondingly installed between the first connecting base 101 and the second connecting base 102, and a plurality of cross braces 4 are correspondingly installed between the first column 1 and the second column 2. The first connecting base 101, the second connecting base 102, the first column 1 and the second column 2 are installed as a whole through the connecting bottom rods 103 and the cross braces 4.

[0031] A slide steel plate 7 is also installed on the upper end of the first column 1 and the second column 2. A sliding platform 8 is arranged on the slide steel plate 7. Automatic welding equipment 9 is correspondingly installed on the sliding platforms 8 on both sides. The sliding platform 8 can drive the automatic welding equipment 9 to move on the slide steel plate 7 accordingly.

[0032] The connecting bottom rod 103 and the cross brace 4 are both configured as lockable sleeve-type telescopic structures, so that the distance between the first column 1 and the second column 2 on both sides is adjustable.

[0033] like Figure 2 As shown, a slideway 3 is further provided at the corresponding end faces of the first column 1 and the second column 2, and a slider 6 is correspondingly provided in the slideway 3. The position of the slider 6 is determined according to the height of the curved steel truss to be welded, and the slider 6 is correspondingly fixed in the slideway 3 by a detachable fastener 10; and a groove 61 is provided on the slider 6, and the two side ends of the cross brace 4 are correspondingly installed in the groove 61 of the slider 6.

[0034] Limiters 5 are installed on both sides of the cross brace 4, and the positions of the limiters 5 on both sides are selected according to the positions of the curved steel trusses to be welded.
