Problems solved by technology

However, the weight of the generator itself is only more than 2 tons, and it cannot be lifted and transported completely by the diesel engine and the generator at each lifting point, because the lifting lugs of the generator cannot bear the weight of the entire diesel generator set

Embodiment Construction

[0056] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] like Figure 1 to Figure 3 As shown, the assembled diesel engine and generator includes diesel engine 1 and generator 2 .

[0058] The diesel engine 1 includes a flywheel disk and a flywheel housing. like Figure 1 to Figure 4 As shown, the generator 2 includes a casing 21, a stator 22, a rotor 23, a bearing and a cover plate (not shown). The front end of the casing is covered with a protective plate 25, and the stator 22 is arranged in the casing 21. A bearing is installed at the rear end of the rotor 23, the bearing is installed in the casing 21, the cover plate is installed on the end face of the casing away from the bearing through bolts, that is, the cover plate is installed on the front end surface of the casing, and the middle part of the cover plate is provided with There is a support hole, the end of the rotor 23 away...

Abstract

The invention discloses assembly, transfer and storage methods for a diesel engine and a generator. A rotor is suspended through a fastening strip for assembly of the generator in the assembly method. Transferring is carried out through a hanger, and the lengths and the load capacity of a first lifting rope, a second lifting rope and a third lifting rope in the hanger are calculated in the transfer method; and transfer and storage are supported through a support frame in the storage method. By using the methods disclosed by the invention, when the diesel engine and the generator are assembled, the fastening strip is convenient and fast to assemble and disassemble, the occupied space is small, assembly is not affected and the cost of the fastening strip is low; when the diesel engine and the generator are transferred, one lifting point of the diesel engine and two support seats of the generator are selected as lifting points, two lifting points of the generator are symmetrically distributed and the three lifting points have stability, so that balance lifting of a whole system can be ensured; and the lengths and the minimum load capacity of the lifting ropes are determined through calculation, and the first lifting rope, the second lifting rope and the third lifting rope are combined into the hanger, so that the design time and the manufacturing cost are reduced.

Description

technical field [0001] The invention relates to a method for assembling, transferring and storing a diesel engine and a generator. Background technique [0002] The single bearing generator has bearing support at the end and no bearing support at the front end. After assembly, it is supported by connecting with the flywheel disk of the diesel engine. [0003] The rotor fixing method of the finished single bearing generator is as follows: the distance between the rotor and the casing is positioned through the front cover plate, that is, the rotor is fixed in the center area of ​​the cover plate by bolts, and the outer ring of the casing and the cover plate is screwed. This ensures that the rotor is level. [0004] During the assembly process, the front cover plate needs to be removed, because the contact surface between the casing and the cover plate is the installation surface that cooperates with the diesel engine. That is, the rotor is connected with the flywheel disc, a...
