Description

Technical Field

[0001] The invention relates to the technical field of gas generator sets, and in particular to a skid-mounted base for a gas generator set. Background Art

[0002] The base of the gas generator set serves as the mounting base for the engine, generator and various supporting parts, and bears a large assembly weight. Therefore, the base is subjected to a large vertical force during the lifting process, which requires the base to have sufficient strength to ensure its reliability and life.

[0003] The inventors found that the existing bases are mostly welded I-beams, and the overall bearing capacity is limited. They can only carry units with a power of 500-800kW. When the unit power reaches 2000kW, it cannot meet the load-bearing requirements and the unit cannot operate smoothly and reliably. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a skid-mounted base for a gas generator set, in which both the bottom beam and the cross beam adopt a square tube structure with strength and rigidity superior to that of I-beams, and the cross beam and the bottom beam are through-welded, which not only makes the overall structure of the gas generator set base simple and compact, but the through-welding connection method makes the connection between the bottom beam and the cross beam more stable and the force transmission effect better, thereby greatly improving the strength and rigidity of the base and solving the problem of limited bearing capacity of the existing generator set base.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In the first aspect, the present invention provides a skid-mounted base for a gas generator set, comprising a bottom beam and a cross beam of a square tube structure, wherein two bottom beams are provided, the two bottom beams are arranged opposite to each other, a plurality of cross beams are arranged between the two bottom beams, the cross beams penetrate the bottom beams and are welded to the bottom beams, and a support base for supporting the generator set is fixedly provided on the bottom beam and the cross beams.

[0007] As a further implementation method, the support base is composed of a machine base plate, a supporting rib plate and vertical ribs. The machine base plate is horizontally arranged, and the machine base plate is connected to adjacent bottom beams and cross beams through a plurality of supporting rib plates and a plurality of vertical ribs.

[0008] As a further implementation, the vertical reinforcement is welded on the cross beam.

[0009] As a further implementation method, each of the machine base plates is correspondingly connected to two cross beams.

[0010] As a further implementation method, the support rib is provided with an engine mounting bolt hole / generator mounting bolt hole.

[0011] As a further implementation, the cross beam is inserted into the bottom beam and extends outward.

[0012] As a further implementation, the end surface of the crossbeam is sealed by reinforcing ribs.

[0013] As a further implementation, a bottom plate is fixedly provided at the bottom of the bottom beam, and a plurality of bottom plates are provided, and the plurality of bottom plates are spaced apart along the length direction of the bottom beam.

[0014] As a further implementation method, a lifting lug is further provided, and the lifting lug passes through the bottom beam and is welded to the bottom beam.

[0015] As a further implementation, the lifting lug is movable.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) The bottom beam and the cross beam of the present invention are both made of square tube structures with strength and rigidity superior to I-beams. The cross beam and the bottom beam are through-welded, which not only makes the overall structure of the gas generator base simple and compact, but also the through-welding connection method makes the connection between the bottom beam and the cross beam more stable and the force transmission effect better, thereby greatly improving the strength and rigidity of the base.

[0018] (2) Each machine base plate of the present invention is connected to two corresponding cross beams to form a rigid stretcher-type structure. Compared with the wide-body cantilever structure of the existing base, it has higher strength and rigidity and better supporting stability.

[0019] (3) The cross beam of the present invention is inserted into the bottom beam and extends outward, which is convenient for welding operation, ensures welding quality and compactness of the structure, and improves the welding strength and stability between the cross beam and the bottom beam.

[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] As introduced in the background technology, the existing bases are mostly welded by I-beams, and the overall bearing capacity is limited. They can only carry units with a power of 500-800kW. When the unit power reaches 2000kW, it cannot meet the load-bearing requirements and the unit cannot operate smoothly and reliably. In order to solve the above technical problems, the present invention proposes a skid-mounted base for a gas generator set.

[0029] Example 1

[0030] In a typical embodiment of the present invention, Figure 1-Figure 4 As shown, a gas generator set skid-mounted base is proposed, including a support base, a bottom beam 4 and a cross beam 5, wherein the bottom beam 4 and the cross beam 5 are both square tube structures with strength and rigidity better than I-beams, two bottom beams 4 are provided, and several cross beams 5 are provided. The two bottom beams 4 are arranged opposite to each other, and several cross beams 5 are arranged between the two bottom beams 4. The cross beam 5 is perpendicular to the bottom beam 4, and the cross beam 5 passes through the bottom beam 4 and is welded to the bottom beam 4.

[0031] Since the cross beam 5 and the bottom beam 4 are through-welded, not only the overall structure of the gas generator base is simple and compact, but the through-welding method also makes the connection between the bottom beam 4 and the cross beam 5 more stable and the force transmission effect better, which greatly improves the strength and rigidity of the base.

[0032] The support base is used for supporting the generator set. The support base is fixed on the bottom beam 4 and the cross beam 5 by welding. Specifically, the support base is composed of a machine base plate 1, a supporting rib plate 2 and a vertical rib 3. The machine base plate 1 is horizontally arranged, and the machine base plate 1 is connected to the adjacent bottom beam 4 and cross beam 5 through a plurality of supporting rib plates 2 and a plurality of vertical ribs 3.

[0033] Specifically, the support rib plate 2 and the vertical ribs 3 are perpendicular to the machine base plate 1 , and the bottom of the machine base plate 1 is connected to the bottom beam 4 and the cross beam 5 through the support rib plate 2 , and the support rib plate 2 improves its support strength and stability through the vertical ribs 3 .

[0034] The support rib plate 2 and the vertical ribs 3 are fixedly connected to the machine base plate 1, the bottom beam 4 and the cross beam 5 by welding, wherein the vertical ribs 3 are welded to the cross beam 5, and each machine base plate 1 is connected to two cross beams 5. The support rib plate 2 is provided with engine mounting bolt holes / generator mounting bolt holes for fixing the engine / generator to the support rib plate 2 together.

[0035] Since each machine base plate 1 is connected to two cross beams 5 , a rigid stretcher-type structure is formed. Compared with the wide-body cantilever structure of the existing base, the strength and rigidity are higher and the supporting stability is better.

[0036] The supporting ribs 2 and the vertical ribs 3 are used to bear the vertical static load and high-frequency dynamic load of the engine / generator. The supporting ribs 2 and the vertical ribs 3 can transfer the load to the seismic isolation foundation of the gas generator set through the bottom beam 4 and the cross beam 5.

[0037] In order to improve the welding strength and stability between the cross beam 5 and the bottom beam 4, the cross beam 5 is inserted into the bottom beam 4 and extends outward. In this embodiment, the end of the cross beam 5 extends outward from the bottom beam 4 by 5 mm to facilitate the welding operation, thereby ensuring the welding quality and the compactness of the structure.

[0038] The end surface of the cross beam 5 is blocked by a reinforcing rib, and the reinforcing rib and the end surface of the cross beam 5 are fixed by welding, so that the cross beam 5 achieves the structural effect of a closed cabin.

[0039] A bottom plate 7 is fixedly provided at the bottom of the bottom beam 4, and the bottom plate 7 is fixedly connected to the bottom beam 4 by welding. There are a plurality of bottom plates 7, which are spaced apart along the length direction of the bottom beam 4 and are mainly used for transferring the load to the foundation.

[0040] A plurality of lifting ears 6 are also provided. In the present embodiment, the lifting ears 6 pass through the bottom beam 4 and are welded to the bottom beam 4, that is, the lifting ears 6 are also through-welded to the bottom beam 4. To facilitate the welding of the lifting ears 6, the lifting ears 6 also extend outward from the bottom beam 4, with an extension length of not less than 5 mm, so as to ensure the simplicity, compactness, strength and rigidity of the overall structure of the gas generator set base.

[0041] In other embodiments, the lifting lug 6 can also be set to be movable. Specifically, when the unit is lifted, the lifting lug 6 is pulled out, and when the unit is running, the movable lifting lug is pushed into the skid-mounted base without occupying the safety passage of the gas unit.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
