Embodiment Construction

[0035] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0036] The present invention will be described in further detail below in conjunction with specific examples, and these examples should not be construed as limiting the scope of protection claimed by the present invention. The term "comprising" when used indicates the presence of a feature, but does not exclude the presence or addition of one or more other features.

[0037] In the prior art, there is a solution in which a support rod 1 is provided at the rear end of the casing of the gas turbine for support. One end of the support rod 1 supports the shell of the gas turbine, and the other end is fixed to the ground, which has the effect of fixing and supporting the rear end of the shell of the ...

Abstract

The invention provides a support device for a gas turbine. The casing of the gas turbine constitutes a cylinder, and a support device is provided at the rear end of the cylinder. The support device includes: a support rod supporting the cylinder, one end of the support rod supports the cylinder, and one end a deflectable elongated rod fixed to the ground; and an anti-tipping assembly of the support rod, the anti-tipping assembly comprising a tilting pad bearing, the support rod at least partially passing through the tilting pad bearing, The tilting pad bearing is configured to allow the support rod to deflect at least within a preset angle range and to bear the load transmitted by the support rod. The invention supports the support bar through the tilting pad bearing, improves the strength of the support bar, prevents the support bar from toppling after deflection, and avoids the limitation of its diameter and material when designing the support bar.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to a support device for a gas turbine and the gas turbine. Background technique [0002] The casing of the gas turbine will be deformed due to thermal expansion, especially the rear end of the casing of the gas turbine is generally used as the relative dead point of the whole machine, which plays an important role in absorbing the thermal expansion and vibration of the whole machine and improving the stability of the whole machine. In the prior art, there is a long-rod support device, which is usually set as a support rod with a certain toughness, so that the support rod can absorb thermal expansion through deflection. Especially for the cylinder of the turbine in the gas turbine, there is a solution in the prior art to support the cylinder at this place by using a support rod. Specifically, during assembly, the support rod is pre-bent at a certain angle, and then under the thermal expa...
