Description
Technical Field
The utility model relates to a fixing structure for a large split assembly combining surface of a hydroelectric generating set.
Background
Under the restriction of road transportation, large parts of the hydroelectric generating set all adopt split structures, and high-strength bolts are stretched on the site of a power station to realize the compression of a combined surface between two correspondingly combined halves; in order to reduce the cost, the combined surface between two petals is compressed by adopting a bolt non-stretching mode made of common materials in the manufacturing process of the split part, and because the structure size and the weight are large, in order to avoid the situation that the combined surface is staggered or gapped in the hoisting process due to small pressing force of the combined surface, a steel plate is usually welded across the combined surface to fix the two petals. The final processing can be finished only by disassembling and combining the split pieces for multiple times in the manufacturing process of the split pieces, so the problem of cutting and welding steel plates on the split pieces for multiple times exists in the combined surface fixing mode. In order to ensure the welding quality, the welding position of the steel plate of the split piece needs to be ground flat due to the welding of a bulge generated by welding and repaired and ground flat due to the pit generated by cutting off the steel plate before welding the steel plate again after cutting off the steel plate each time, if the split piece is made of a high-strength material, the combination surface of the split piece needs to be preheated each time before welding the steel plate, the production efficiency is seriously influenced, and meanwhile, the combination surface is deformed and other product quality problems are influenced due to the preheating, welding, cutting off and repairing welding of the two sides of the combination surface of the split piece for many times. In order to avoid the above problems, it is necessary to provide a fixing structure for a large split component assembly surface of a hydroelectric generating set.
Disclosure of Invention
The utility model aims to provide a fixing structure for a combined surface of a large-scale split component of a hydroelectric generating set, which has the advantages of simple operation, strong universality, low labor intensity, high efficiency and small damage to product quality, and the technical scheme is as follows: the connecting device consists of a first bottom plate, a second bottom plate, a first connecting plate, a second connecting plate and a third connecting plate;
the split-type solar water heater is characterized in that one side of a combined face of the first base plate and the split piece is fixed through a three-face fillet weld, the other side of the combined face of the second base plate and the split piece is fixed through a three-face fillet weld, one side of the first connecting plate and the first base plate are fixed through a three-face fillet weld, the other side of the first connecting plate and the second base plate are fixed through a three-face fillet weld, two sides of the second connecting plate and the first connecting plate are fixed through a three-face groove weld, a first U-shaped groove is formed in the second connecting plate and located on the side of the combined face of the first connecting plate, two sides of the third connecting plate and the second connecting plate are fixed through a three-face groove weld, a second U-shaped groove is formed in the third connecting plate and located on the side of the combined face of the second connecting plate.
Technical effects
1. The combined surface is fixed for the first time by welding the two bottom plates on two sides of the combined surface respectively, the first connecting plate is cut at the middle position of the length to complete first valve disassembly without being directly welded with the valve splitting piece, the second connecting plate is welded on the first connecting plate to complete second valve disassembly, the second connecting plate is cut at the middle position of the length to complete third fixing of the combined surface, and the third connecting plate is cut at the middle position of the length to complete third valve disassembly; two bottom plates are cut off before delivery after the split piece is manufactured, only one-time bottom plate welding, cutting off, concave point repair welding, grinding and flattening and convex point grinding are carried out on the split piece in the whole manufacturing process, the split piece made of high-strength materials is preheated once, and the hidden danger of deformation quality of the split piece caused by the fact that steel plates are welded and cut off on the split piece for multiple times is avoided.
2. The connecting plates are cut at the middle position in the length direction to complete the valve dismantling, so that the problems of large workload and low efficiency caused by the fact that the valve is dismantled by cutting the welding seams between the first connecting plate and the bottom plate and the welding seams among the connecting plates are solved.
3. According to the utility model, the first U-shaped groove is arranged on the second link plate, the first U-shaped groove is positioned on the side of the combined surface of the first link plate, the second U-shaped groove is arranged on the third link plate, and the second U-shaped groove is positioned on the side of the combined surface of the second link plate, so that the second link plate can be directly welded on the first link plate and the third link plate when the combined surface is fixed, the problem that salient points are generated at the cut of the first link plate and the cut of the second link plate due to the cutting of the split piece when the second link plate and the third link plate are welded is solved, the operation is simple, the efficiency is high, and the labor intensity and the cost are reduced.
4. According to the utility model, three-side welding seams are adopted on two sides of the combined surface of the two bottom plates and the split component, the first connecting plate and the two bottom plates, the second connecting plate and the first connecting plate, and the third connecting plate and the second connecting plate, so that the reliability of fixing the combined surface is ensured.
5. The groove welding seams are adopted between the second connecting plate and the first connecting plate and between the third connecting plate and the second connecting plate, so that the length and the width of the three connecting plates are the same, and the problem that the fixed strength of a combined surface is reduced because the size of the rear connecting plate is smaller than that of the front connecting plate due to the fillet welding seam is solved.
6. The number of the third connecting plates can be increased or reduced according to the fixing times of the combined surfaces in the manufacturing process of the split piece, and the split piece is high in universality.
7. The split piece fixing device is novel in concept, is particularly suitable for fixing the combined surface in the manufacturing process of split pieces with large structural size and weight, and is easy to popularize.
