Description

Technical Field

[0001] This utility model belongs to the field of steam turbine technology, and more specifically relates to a steam turbine chassis with an oil tank. Background Technology

[0002] Steam turbines are a type of power equipment widely used in power generation and industrial fields. During operation, they require a large amount of lubricating oil to ensure the normal operation of various components. In order to store and supply lubricating oil, steam turbines are usually equipped with chassis oil tanks (such as the published patent with publication number CN222976890U, entitled "A Skid-Mounted Oil Tank Assembly for Steam Turbines").

[0003] Traditional steam turbine chassis oil tanks are mostly fixed with several bolts. When replacing or repairing them, maintenance personnel either have to crawl directly into the chassis to carry out the repairs, which is difficult due to the limited space inside the chassis, or they have to disassemble the oil tank, but the disassembly efficiency is also low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steam turbine chassis with an oil tank, in which the oil tank is slidably mounted on the chassis. When maintenance or disassembly is required, the oil tank can be completely removed, thus facilitating maintenance, disassembly, and replacement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steam turbine chassis with an oil tank, wherein a slide rail and slider structure is provided between the oil tank and the chassis, and a slider is provided at the bottom of the oil tank, a slide rail is provided on the chassis, a sliding or detachable locking plate is provided on the side of the chassis, and a corresponding locking groove is provided on the oil tank, wherein the oil tank is fixed after the locking plate is inserted into the locking groove and fixed.

[0006] Furthermore, a support plate is provided between the chassis and the oil tank, the oil tank is mounted on the support plate, the slider is located at the bottom of the support plate, and the slot is located on the support plate.

[0007] Furthermore, one end of the support plate extends toward the side of the chassis, and a caster wheel is provided at the bottom of the extension section, with the caster wheel contacting the ground. A handle is provided at the end of the extension section.

[0008] Furthermore, a detachable fixing block is provided on the extension section of the support plate, and a positioning block is provided on both sides and the other end of the support plate. The fixing block and the positioning block form an oil tank placement area, and the outer wall of the oil tank contacts the fixing block and the positioning block.

[0009] Furthermore, the chassis is provided with a support block corresponding to the slide rail, and the support block is provided with a slide groove corresponding to the slide rail, so that the slide rail slides in the slide groove, and a limit block is provided on the slide rail to limit the sliding distance of the slide rail.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by sliding the oil tank on the chassis, the oil tank can be completely removed when maintenance or disassembly is required, thus making maintenance, disassembly and replacement more convenient.

[0016] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0017] A steam turbine chassis with an oil tank includes a slide rail and slider structure between the oil tank 1 and the chassis 2. The oil tank 1 has a slider 3 at its bottom, and the chassis 2 has a slide rail 4. The side of the chassis 2 has a sliding or detachable retaining plate 5. The oil tank 1 has a corresponding retaining groove 6 for the retaining plate 5. The retaining plate 5 is engaged with the retaining groove 6 and fixed, thus securing the oil tank 1. Figure 1As shown, in this preferred embodiment, a support plate 7 is provided between the chassis 2 and the oil tank 1, the oil tank 1 is mounted on the support plate 7, the slider 3 is located at the bottom of the support plate 7, and the slot 6 is located on the support plate 7. Figure 1 As shown, in this preferred embodiment, one end of the support plate 7 extends towards the side of the chassis 2, and a caster wheel 8 is provided at the bottom of the extension section 9, with the caster wheel 8 contacting the ground. A handle 10 is provided at the end of the extension section 9. Figure 1 As shown, in this preferred embodiment, a detachable fixing block 11 is provided on the extension section 9 of the support plate 7, and positioning blocks 12 are provided on both sides and one end of the support plate 7. The fixing block 11 and the positioning block 12 form an oil tank placement area, and the outer wall of the oil tank 1 contacts the fixing block 11 and the positioning block 12. Figure 1 and Figure 2 As shown, in this preferred embodiment, the chassis 2 is provided with a support block 13 corresponding to the slide rail 4. The support block 13 is provided with a groove corresponding to the slide rail 4, allowing the slide rail 4 to slide within the groove. A limit block (not shown in the attached figure) is provided on the slide rail 4 to limit the sliding distance of the slide rail 4. Supported by the support block 13, the slide rail 4 can slide on the support block 13, thereby increasing the length of the support plate 7 that slides out, allowing the oil tank 1 on the support plate 7 to completely slide out of the chassis 2 for easy maintenance. The limit block limits the sliding distance of the slide rail 4. Specifically, a limit block corresponding to the slider 3 is provided on the slide rail 4 to limit the maximum stroke of the slider 3. Figure 1 and Figure 2 As shown, the fuel tank 1 is placed on the support plate 7. The support plate 7 is fixed by the cooperation of the clamping plate 5 and the clamping groove 6. When the fuel tank 1 needs to be repaired, the clamping plate 5 is moved or removed so that it is removed from the clamping groove 6. The support plate 7 can then be pulled out of the chassis 2 by the handle 10. When pulled out, the slider 3 at the bottom of the support plate 7 can slide, and the slider 3 on the slide rail 4 can also slide, so that the fuel tank 1 can be completely removed from the chassis 2, making it convenient for maintenance personnel to maintain the fuel tank 1. Alternatively, the fixing block 11 on the support plate 7 can be removed so that the fuel tank 1 can be moved out laterally, or the support plate 7 can be lifted off by a crane using the lifting ring or hook on the fuel tank 1, making it easier to disassemble the fuel tank 1.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
