Description
Technical Field
[0001] The utility model belongs to the technical field of diesel generator sets, and in particular relates to a common base for a diesel generator set. Background Art
[0002] The high-power diesel generator set for ships mainly includes a diesel engine and a generator. In the prior art, the diesel engine and the generator are installed on the same plane of an integral common base. Due to the small space in the ship's engine room, customers generally require the diesel generator set to be compact in size and highly integrated: that is, the peripheral equipment that can be installed can be installed, saving the space occupied by the peripheral equipment. The above two improvements can improve the competitiveness of the product.
[0003] However, the diesel generator sets in the prior art generally have the following problems:
[0004] (1) As the power or efficiency of the generator increases, the size of the generator increases, which makes it difficult to arrange the generator on a common base. Due to space constraints, the installation and connection between the components are not easy to operate.
[0005] (2) The plate cooler, pre-lubricating electric oil pump, oil filter and temperature control valve of the generator set are not installed on the diesel engine and the generator set, but occupy the peripheral space and are connected to the diesel engine pipeline, resulting in a less compact structure, large space occupation and low integration.
[0006] (3) If the diesel engine and the generator are installed on the same plane of the integral common base, and the center height of the generator is kept the same as the center height of the diesel engine, the part of the common base where the generator is installed needs to be widened. Due to the widening of the generator part, the shape of the upper plate of the common base is irregular, resulting in a lot of waste when cutting the steel plate; in addition, due to the widening of the generator part of the common base, the weight increases and the cost increases. And after the part of the common base where the generator is installed is widened, if multiple generator sets are required to be arranged on the ship, in order to reserve maintenance space, the distance between the two generator sets needs to be increased, and the occupied space increases. Utility Model Content

[0037] An embodiment of the utility model disclosed in the present invention is as follows Figures 1 to 4 As shown in common, the common base for the diesel generator set includes a mounting frame, which includes a base plate 100, two bottom supporting and connecting long blocks and two side uprights arranged oppositely, the two bottom supporting and connecting long blocks are respectively a first bottom supporting and connecting long block 105 and a second bottom supporting and connecting long block 107, the two side uprights are respectively a first side upright 103 and a second side upright 104, the first bottom supporting and connecting long block 105 is respectively fixedly connected to the bottom end of the first side upright 103 and one side of the base plate, the second bottom supporting and connecting long block 107 is respectively fixedly connected to the bottom end of the second side upright 104 and the other side of the base plate.
[0038] like Figure 4As shown, usually the thickness of the bottom support connecting long block is greater than the thickness of the bottom plate 100, that is, the thickness of the first bottom support connecting long block 105 and the second bottom support connecting long block 107 is greater than the thickness of the bottom plate 100. In this way, the weight can be reduced while ensuring the strength.
[0039] The installation frame is provided with a generator installation area 2, a diesel engine installation area 1 and an auxiliary installation area 3 for installing auxiliary systems.
[0040] The tops of the two side vertical plates of the diesel engine installation area 1 are respectively fixed with diesel engine mounting plates, which are respectively denoted as the first diesel engine mounting plate 101 and the second diesel engine mounting plate 102.

[0041] The position of the diesel engine mounting plate is higher than that of the generator mounting plate, that is, the mounting plane of the diesel engine is higher than that of the generator. Compared with the traditional common base, there is no need to widen the part of the common base for mounting the generator, which not only reduces the overall occupied space, but also greatly reduces the weight of the common base for the diesel engine generator set. To improve the strength, the upper and lower overlapping parts of the diesel engine mounting plate and the generator mounting plate are fixedly connected by a transition connecting rib 8.
[0042] Symmetrical vibration isolator mounting plates are fixed to the outer side walls of the two side vertical plates, respectively, and are respectively denoted as the first vibration isolator mounting plate 4 and the second vibration isolator mounting plate 5.

The lifting lug is located in the diesel engine installation area 1, and the lifting lug 12 on the first side vertical plate 103 and the lifting lug 12 on the second side vertical plate 104 are symmetrically arranged. This arrangement can prevent the common base for the diesel engine generator set from being deflected during the lifting process.
