Description

Technical Field

[0001] This utility model relates to the field of steel caisson assembly and welding technology, and in particular to a large steel caisson assembly jig device that does not require marking or coding. Background Technology

[0002] Compared to conventional concrete or reinforced concrete caissons, steel caissons are more likely to meet requirements such as greater burial depth, stronger integrity, better stability, and a larger load-bearing area. Currently, larger bridge construction projects require larger caissons with deeper burial depths, making steel caissons one of the best choices for caisson foundations.

[0003] The fabrication of steel caissons mainly involves the manufacturing of individual plate units. For straight, cross-shaped, and arc-shaped segments, the primary focus is on the fabrication of inner and outer wall panels and ring plate units. In typical fabrication, a jig is erected according to the linear orientation of the steel caisson plate units. After the jig is erected, the plate units are placed on it, and then steel plates are assembled, stiffened, positioned, and welded sequentially according to the drawings. Finally, the plate units are trimmed. In traditional processes, plate unit assembly requires marking, positioning, and welding. After assembly, plumb bobs, steel tape measures, and total stations are used for measurement to ensure the assembly accuracy of the plate units. When steel structure products are fabricated in the factory, the conventional inspection method involves using steel tape measures and plumb bobs for manual measurement, which is inaccurate and inefficient. Furthermore, traditional assembly methods can easily damage the base material during construction.

[0004] This large steel caisson assembly frame, which does not require marking, is mainly used for steel caisson ring plate units and truss units. Traditional assembly methods are not very accurate and have low assembly efficiency, which directly affects the construction progress, efficiency, and quality of steel structure products. Utility Model Content

[0005] The purpose of this utility model is to provide a large steel caisson assembly frame device that does not require marking or coding, thereby solving the technical problems of low accuracy and low efficiency in the existing steel caisson assembly without marking, which directly affects the construction progress.

[0006] Using the non-marking jig of this application avoids these problems. This jig adopts a magnetic telescopic structure and is equipped with a horizontal display device and a hydraulic clamping device. When manufacturing the ring plate unit, simply align it directly with the magnetic limiting devices on both sides and fix it with the hydraulic clamping device, which is convenient and simple. This not only improves work efficiency but also avoids damage to the base material caused by plate positioning and reduces the use of stacking plates.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A large steel caisson assembly frame device without marking or coding includes a frame base plate, a magnetic limiting plate, a positioning plate, an anti-slip rubber pad, and a support base. The frame base plate is set on the support base, the anti-slip rubber pad is set on both sides of the frame base plate, the positioning plate is set on the frame base plate, and the magnetic limiting plate is movably set on the support base and is set on both sides of the frame base plate.

[0009] Furthermore, the outer side of the anti-slip rubber pad is provided with several anti-slip rubber block countersunk heads, which are fixed to the base plate of the jig frame by bolts.

[0010] Furthermore, several positioning plates are provided, and these positioning plates are set according to the positional structure of the assembled steel caisson components.

[0011] Furthermore, the support base includes support columns, a bottom support plate, and crossbars. The bottom support plate is located at the bottom of the support columns, the crossbars are located between two support columns, and the base plate of the jig is located on several crossbars.

[0012] Furthermore, the upper end of the support column is provided with several bolt holes, and the two ends of the crossbar are provided with several bolt holes. The support column and the crossbar are fixed by fastening positioning bolts. The position of the bolts connecting the support column and the crossbar is adjusted according to the size of the assembled steel caisson and the assembly height.

[0013] Furthermore, a level detection plate is provided on the base plate of the tire frame, and a level observation bubble is provided on the top of the level detection plate.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0015] This invention addresses the mass assembly of sheet metal of the same type or different sizes using magnetic limit adjustment, eliminating the need for marking during assembly. The assembly is reusable, significantly improving production efficiency. Furthermore, the device is equipped with a bubble level and a ruler to maximize assembly accuracy, thereby ensuring product quality and indirectly accelerating production. Positioning bolts accommodate different height requirements, allowing for simultaneous assembly of multiple sheet metal pieces. This reduces the need for manpower and equipment, improving both construction efficiency and product assembly quality. Attached Figure Description

However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0019] like Figure 1 As shown, a large steel caisson assembly frame device without marking or coding includes a frame base plate 1, a magnetic limiting plate 2, a positioning support plate 3, an anti-slip rubber pad 4, a hydraulic clamping device, and a support base. The frame base plate 1 is mounted on the support base, the anti-slip rubber pad 4 is mounted on both sides of the frame base plate 1, the positioning support plate 3 is mounted on the frame base plate 1, the magnetic limiting plate 2 is movably mounted on the support base and on both sides of the frame base plate 1, and the hydraulic clamping device is movably mounted on the support base and on both sides of the frame base plate 1. The magnetic limiting plate 2 uses magnetic attraction to hold the assembly components in place, the positioning support plate 3 is used to limit the position of the assembly components, the anti-slip rubber pad 4 is used to increase the friction of the assembly components and prevent them from moving, and the hydraulic clamping device is used to clamp two or more assembly components.

[0020] Assembly method: Place the base plate of the jig assembly horizontally, and connect the hydraulic clamping device to the base plate by welding. The magnetic limit assembly has a positioning plate, which is connected by tightening positioning bolts. The plate has a level observation bubble, which is connected to the plate with strong adhesive. The magnetic limit assembly is connected to the base plate with countersunk positioning bolts.

[0021] Compared with existing technologies, this positioning device assists in the positioning and assembly of rods, allowing for disassembly and movement, improving assembly accuracy, freeing up hands and enhancing safety, and improving the quality and efficiency of plate unit assembly.

[0022] In this embodiment of the utility model, a plurality of anti-slip rubber block countersunk heads 5 are provided on the outer side of the anti-slip rubber pad 4, and the anti-slip rubber block countersunk heads 5 are fixed to the base plate 1 of the jig frame by bolts.

[0023] In this embodiment of the utility model, the positioning support plate 3 is provided with several pieces, and the positioning support plate 3 is set according to the position structure of the assembled steel caisson assembly.

[0027] After the panels are placed on the jig, the finished product unit uses magnetic positioning to locate the panel units. The jig's base plate is equipped with a level indicator and a scale. Adjustments are made according to the panel unit size, and the level indicator is used to check if the panel is level. Once the panel is correctly positioned, it is clamped using a hydraulic clamping device. Anti-slip rubber blocks are placed next to the panel to prevent shifting during construction. The anti-slip rubber blocks are connected to the jig's base plate using countersunk positioning bolts. The jig's uprights and the hydraulic clamping device are equipped with fixing bolts to accommodate panels of different heights and widths. After all the above steps are completed, the panel units can be assembled. For panels of the same type and size, the jig does not require adjustment; assembly can proceed directly onto the jig without marking or positioning.
