[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-9 This utility model provides a caster fixture applicable to the field of gas turbines, specifically a caster fixture for gas turbine entry and exit from the nacelle, including mounting seats 21 disposed on both sides of the gas turbine base frame 2 and caster devices 3 detachably fixed on the mounting seats 21 for supporting the gas turbine when exiting the nacelle.

[0031] Caster device 3 includes:

[0032] The support plate 31 is fixedly connected to the mounting base 21 by connecting bolts 311;

[0033] The movable part 32 is angle-adjustable and is located at the lower end of the support plate 31 and abuts against the track 1;

[0034] Adjusting member 33 is disposed on support plate 31 and connected to moving member 32, and is used to adjust the installation angle of moving member 32 on track 1. Track 1 includes axial track 12 arranged axially and transverse track 13 arranged transversely on axial track 12.

[0035] It should be noted that during operation, when the gas turbine being transported at sea is being moved out of the hull, the caster device 3 is fixed to the mounting plate 211 on the mounting base 21, and then the moving part 32 is transported onto the track 1 to move the gas turbine out of the hull. The installation angle of the moving part 32 is adjusted by the adjusting part 33, so that the gas turbine can move axially and laterally on the track 1. The caster device 3 is fixed to the gas turbine base frame 2 by four sets of matching connecting bolts 311. The adjusting part 33 adjusts the lateral and longitudinal directions of the caster device 3. This method can be applied not only to land-based units, but also takes into account the tilting and swaying motion characteristics of offshore platforms. It has the characteristics of fixed movement direction of directional casters, and also meets the engineering practical requirements of sliding reversal. This enhances the stability and reliability of the equipment being moved out of the hull, reduces the requirements of the width of the track 1 for the gas turbine being moved out of the hull, and improves the efficiency of the gas turbine being moved out of the hull.

[0036] In one embodiment, the movable member 32 includes a support frame 321 disposed at the lower end of the support plate 31, a bolt shaft 322 spaced through the support frame 321, and a roller 323 sleeved on the bolt shaft 322 and located inside the support frame 321. A bearing 324 is disposed between the roller 323 and the bolt shaft 322.

[0037] This design is for reference. Figures 1-6 The support plate 31 and the support frame 321 are connected by bolts to ensure that the bottom surface of the support plate 31 is flush with the bottom surface of the gas turbine base frame 2. The length of the support frame 321 is slightly less than the length of the support plate 31. The total height of the roller 323 and the support frame 321 is the height of the base frame 2 from the track 1. The roller 323 allows the gas turbine to slide easily across the track 1 during movement, reducing frictional resistance and improving the smoothness of movement. Moreover, the directional roller 323 is more stable during movement than the universal wheel. The support frame 321 provides a stable support for the roller 323, ensuring that the roller 323 can remain stable when bearing the weight of the gas turbine and is not easily deformed or damaged. The bolt shaft 322 is spaced through the support frame 321, which enhances the structural strength of the entire moving part 32 and enables it to withstand greater loads. As vulnerable parts, the roller 323 and bearing 324, as well as the design of the bolt shaft 322, make the entire moving part 32 easy to disassemble and assemble, and convenient for maintenance and upkeep.

[0038] In one embodiment, the adjusting member 33 includes a pivot bolt 331 passing through the support plate 31 and connected to the support frame 321, and a positioning bolt 332 disposed on the support plate 31 and connected to the support frame 321. The support plate 31 has a fixing hole 3103 for installing the pivot bolt 331, and a first positioning hole 3101 and a second positioning hole 3102 for installing the positioning bolt 332. The first positioning hole 3101 and the second positioning hole 3102 are equidistant from the fixing hole 3103. The support frame 321 has a connecting hole 32101 for fixing the pivot bolt 331 at the position corresponding to the pivot bolt 331, and an adjusting hole 32102 for fixing the positioning bolt 332 at the position corresponding to the positioning bolt 332. The adjusting hole 32102 is positioned corresponding to the second positioning hole 3102 and the first positioning hole 3101.

[0039] This design is for reference. Figure 5 The pivot bolt 331 serves as a rotating shaft, allowing the support frame 321 (which in turn drives the roller 323) to be angled relative to the support plate 31. This allows the tooling to adapt to movement in different directions along the track 1, improving the tooling's flexibility and adaptability. The positioning bolt 332 engages with the adjustment hole 32102 of the support frame 321 through the first positioning hole 3101 and the second positioning hole 3102. This allows the support frame 321 to be securely fixed in position after the angle is adjusted. When the positioning bolt 332 is fixed in the first positioning hole 3101, the support frame 321 is parallel to the base frame 2. When the positioning bolt 332 is fixed in the second positioning hole 3102, the support frame 321 is perpendicular to the base frame 2. This dual positioning design ensures the tooling remains stable during movement, possessing both the characteristics of directional casters fixing the direction of movement and meeting the engineering practical requirements of sliding reversal. This enhances the stability and reliability of the equipment during its outboard operation.

[0040] Example 2

[0041] In one embodiment, the adjusting member 33 further includes a rotating rod 341 that passes through the support plate 31 and is connected to the support frame 321, a rotating disk 342 fixed to the upper end of the rotating rod 341, and a fixing bolt 343 that passes through the rotating disk 342. The fixing bolt 343 passes through the support plate 31 and is fixedly connected to the support frame 321. The rotating disk 342 has a mounting hole 34201 for mounting the fixing bolt 343.

[0042] This design is for reference. Figures 7-9The rotating rod 341 is connected to the support frame 321, allowing the operator to easily adjust the angle of the support frame 321 (and roller 323) by manually rotating the rotating rod 341. The operator can more precisely control the rotation angle of the support frame 321 through the rotating disk 342, meeting the high precision requirements for angle adjustment, making the adjustment process of the roller 323 more intuitive and convenient. The fixing bolt 343 passes through the rotating disk 342 and the support plate 31 and is fixedly connected to the support frame 321, ensuring the stable connection of the adjusted support frame 321. The mounting hole 34201 opened on the rotating disk 342 makes the installation and removal of the fixing bolt 343 simpler and more convenient.

[0043] In one embodiment, a reinforcing rib 312 is fixed on the support plate 31.

[0044] This design is for reference. Figure 4 ,as well as Figure 5 The support plate 31 adopts an L-shaped design, and the reinforcing ribs 312 are fully welded to the support plate 31 to improve the structural strength. The reinforcing ribs 312 do not interfere with the bolts on the support plate 31. As an additional structure of the support plate 31, the reinforcing ribs 312 can significantly improve the strength and rigidity of the support plate 31, so that the support plate 31 can withstand greater loads and stresses without easily deforming or breaking.

[0045] In one embodiment, a limiting strip 11 is provided on the track 1 to restrict the roller 323.

[0046] This design is for reference. Figures 1-5 The existence of a gap between the roller 323 and the limiting strip 11, and the height of the limiting strip 11 being less than the distance from the vertical plate of the support frame 321 to the track 1, allows the limiting strip 11 to restrict the lateral movement of the roller 323 on the track 1, ensuring that the roller 323 always travels along the predetermined track 1 direction, which helps to improve the stability of the equipment or tooling during operation and reduce shaking or tilting caused by the offset of the roller 323.

[0047] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
