Embodiment 1
[0025] This embodiment provides a heavy-duty gas turbine pre-assembly method combining vertical and horizontal assembly, which is characterized in that: the heavy-duty gas turbine pre-assembly method using vertical and horizontal assembly includes vertical assembly and horizontal assembly of two parts.
[0026] According to the structural characteristics of heavy-duty gas turbines, a heavy-duty gas turbine is taken as an example to explain the technical points of this patent. figure 1 .
[0027] Assemble the third cylinder 3, the fourth cylinder 4, the first cylinder 1 and the second and second cylinders 2 in a vertical state, turn the assembled third cylinder 3 and fourth cylinder 4 to the level and drop them on the first support 6 and the second support 7, and then horizontally assemble the fifth cylinder 5 and the assembled first cylinder 1 and second cylinder 2.
[0028] According to the existing heavy-duty gas turbine structure, the pre-assembly of the cylinder is as fo...

The invention discloses a method for preassembling a heavy gas turbine in combination of vertical and horizontal assembling. The method comprises the vertical assembling and the horizontal assembling; a front installation edge and axial sizes of a third cylinder, and the front installation edge and axial sizes of a fourth cylinder are measured; a first support and a second support are adjusted to be horizontal by using a leveling instrument; the fourth cylinder is put on a platform; the third cylinder is assembled on the fourth cylinder by using a process guide piece at the vertical state; the third cylinder and the fourth cylinder which are assembled are hoisted up vertically and turned to the horizontal state; a second cylinder is arranged on the platform vertically; a fifth cylinder is turned over to be horizontal by using a length-adjustable hoisting tool; the first cylinder and the second cylinder which are assembled are hoisted up vertically; the assembled cylinders are turned over to the horizontal state; and the hoisting tool is dismantled so as to realize the preassembling of the turbine. The method has the advantages that the tooling design period and the manufacturing cost are saved; the requirements on assembling field are not so strict; and meanwhile operation personnel can perform assembly more conveniently; and the assembling period is shortened by about 1 / 4.
Description
technical field [0001] The invention relates to the field of pre-assembly of heavy-duty gas turbines, in particular to a method for pre-assembly of heavy-duty gas turbines that combines vertical and horizontal assembly. Background technique [0002] At present, the pre-assembly of heavy-duty gas turbines is all vertical assembly, that is, the cylinders are dropped on the flip base step by step, and flipped to the horizontal after the assembly is completed. Since heavy-duty gas turbines of different structures require different tooling equipment such as turning bases and walking platforms, and at the same time have relatively strict requirements on the height and size of the assembly site, it is difficult to achieve. Contents of the invention [0003] The purpose of the present invention is to realize the pre-assembly of heavy-duty gas turbines by using the existing site conditions without designing and manufacturing complex tooling for heavy-duty gas turbines of different ...
