[0028] The following further describes the present invention in detail with reference to specific embodiments, so that those skilled in the art can understand the present invention more clearly.

[0029] It should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0030] This embodiment provides a complete machine packing device for a quick-installation generator, as Figure 1 shown, which includes a bottom plate 1, a chassis 2, a pressing plate structure 3, a baffle 4, a protective layer 5 filled between the journal and the bearing bush, and a steel wire rope 6 for pulling and fixing the stator lifting lugs.

[0031] In the complete machine packing device provided in this embodiment, the chassis 2 is arranged on the bottom plate 1. The chassis 2 is used for installing the generator, and the stator, end cover, rotor, and bearings of the quick-installation generator are all fixed on the chassis 2, so that the whole quick-installation generator can be fixed on the bottom plate 1.

[0032] The difficulty in packing the complete machine lies in the protection of the journal and the bearing bush, as well as the anti-movement during transportation (including the sliding of the shaft and the chassis). Based on the above problems, in the quick-installation generator complete machine packing device provided in this embodiment, the protective layer 5 is filled in the gap between the journal and the bearing bush. The protective layer 5 can be made of a new type of composite material, which has high mechanical strength, high heat resistance grade, and good insulation performance. Tightening it in the gap between the journal and the bearing bush can play a very good protective role for the journal and the bearing bush.

[0033] Secondly, in this embodiment, the shaft head coupling is clamped by the pressing plate structure 3, and then the shaft tail is clamped by the baffle 4.

[0034] Finally, since the generator has a certain height and the stator is the heaviest and largest component, in this embodiment, it is fastened to the chassis. By pulling and fixing the stator lifting lugs with the steel wire rope 6, it is equivalent to horizontally fastening the entire generator. Thus, the fixation of each component of the generator can be completed. After the assembly is completed, all covers are closed, the oil inlet is blocked, and rust prevention treatment is also required for the rust prevention area. After all components are fixed, the whole package is wrapped and fixed with a rainproof cloth for transportation. After arriving at the site, it can be directly installed without scraping the bearing bush and without hoisting the rotor. Only the anchor bolts need to be installed according to the actual situation, which effectively reduces the transportation cost and greatly reduces the installation workload of the user.

[0035] Specifically, in this embodiment, as Figure 2 、 3As shown, the pressing plate structure 3 includes a first nut 306, a support plate 302, a pressing plate 305, and a second nut 307 arranged in sequence from left to right. The pressing plate structure 3 further includes a bolt 303 and a second base plate 301. A first through hole is provided on the side wall of the support plate 302, and a second through hole is provided on the side wall of the pressing plate 305. The bolt 303 passes through the first through hole and the second through hole at the same time. The left and right ends of the bolt 303 are respectively screwed with the first nut 306 and the second nut 307. The support plate 302 and the pressing plate 305 form a clamping structure for clamping the shaft coupling. A first fixing hole 304 adapted to the shaft head is further provided on the side wall of the support plate 302. The second base plate 301 is fixedly installed on the chassis 2, and the support plate 302 is fixedly installed on the second base plate 301.

[0036] The support plate 302 and the pressing plate 305 together form a clamping structure, which can clamp the shaft coupling. Then, the clamping structure is locked by the first nut 306 and the second nut 307. At the same time, the shaft head is inserted into the first fixing hole 304 to limit the shaft head, effectively improving the stability of the shaft coupling during transportation.

[0037] The baffle 4 is fixedly installed on the chassis 2, and the baffle 4 is provided with a second fixing hole adapted to the shaft tail. Inserting the shaft tail into the second fixing hole can complete the limit of the shaft tail.

[0038] In this embodiment, a spacer 308 can be clamped between the support plate 302 and the pressing plate 305. The thickness of the spacer 308 is equal to the thickness of the shaft coupling. The setting of the spacer 308 can make the force on the pressing plate 305 more uniform, and can prevent the pressing plate 305 from tilting or bending due to force on only one side.

[0039] Among them, at least two washers 309 can be sleeved on the outside of the bolt 303. One washer 309 is arranged between the first nut 306 and the support plate 302, and the other washer 309 is arranged between the pressing plate 305 and the second nut 307. The setting of one washer 309 can prevent relative sliding between the first nut 306 and the support plate 302. Similarly, the setting of the other washer 309 can also prevent relative sliding between the pressing plate 305 and the second nut 307. In this way, when rotating the first nut 306 or the second nut 307, the distance between the first nut 306 and the second nut 307 can be stably adjusted, so that the clamping structure holds the shaft coupling.

[0040] Among them, the second through hole may be a strip-shaped hole. In this way, the bolt 303 can slide within the second through hole, that is, the pressing plate 305 can slide back and forth relative to the bolt 303 along the direction of the strip-shaped hole. In this way, the pressing area of the pressing plate 305 on the coupling can be adjusted.

[0041] The pressing plate structure 3 further includes a first reinforcing rib 310. One end of the first reinforcing rib 310 is fixedly connected to the second bottom plate 301, and the other end of the first reinforcing rib 310 is fixedly connected to the support plate 302. The setting of the first reinforcing rib 310 can enhance the stability of the support plate 302.

[0042] Among them, the second bottom plate 301 may be welded to the chassis 2, and a channel steel for enhancing the stability of the second bottom plate 301 may be provided on the chassis 2. The support plate 302 may be welded to the second bottom plate 301. One end of the first reinforcing rib 310 may be fixedly welded to the support plate 302, and the other end of the first reinforcing rib 310 may also be fixedly welded to the support plate 302.

[0043] In this embodiment, as Figure 4 、 5 shown, the baffle 4 includes a limiting plate 401 and a clamping plate 402. A limiting groove 403 adapted to the clamping plate 402 is provided on the side wall of the limiting plate 401. The clamping plate 402 is embedded in the limiting groove 403 to form a stable structure. The second fixing hole is provided on the side wall of the clamping plate 402, and the limiting plate 401 is fixedly installed on the chassis 2.

[0044] The limiting groove 403 may be a circular groove. The clamping plate 402 is embedded in the limiting groove 403 to form a stable structure, and then the shaft tail is inserted into the second fixing hole to form a stable structure, so as to limit the shaft tail, effectively improving the stability of the shaft tail during transportation. Moreover, the limiting plate 401 may be vertically arranged, so that the clamping plate 402 is equivalent to being arranged inside the limiting plate 401, without occupying the outer space, and fully reducing the floor area of the device.

[0045] Among them, the baffle 4 further includes a second reinforcing rib 405. One end of the second reinforcing rib 405 is fixedly connected to the chassis 2, and the other end of the second reinforcing rib 405 is fixedly connected to the limiting plate 401. The setting of the second reinforcing rib 405 can improve the stability of the limiting plate 401.

[0046] One end of the second reinforcing rib 405 may be fixedly welded to the chassis 2, and the other end of the second reinforcing rib 405 may also be fixedly welded to the limiting plate 401.

[0047] Among them, the side surface of the limit plate 401 is a triangular structure. This is because the limit plate 401 is vertically arranged. During installation, there is no position for welding support in the middle of the bottom of the limit plate 401 (there is no welding position on the chassis 2). If it is a triangular plate, then supports can be welded on both sides of the bottom of the limit plate 401, thereby improving the firmness of the limit plate 401.

[0048] In this embodiment, please refer to again Figure 1 , a limit block 7 for preventing the chassis 2 from sliding is provided on the bottom plate 1. The size of the limit block 7 can be selected according to the size and weight of the generator. The limit block 7 can be temporarily welded and fixed on the bottom plate 1, and the limit block 7 can be an iron block.

[0049] In this embodiment, a rubber plate 8 is provided between the bottom plate 1 and the chassis 2. The setting of the rubber plate 8 can enhance the friction between the bottom plate 1 and the chassis 2, and further improve the stability of the chassis 2.

[0050] In the present invention, the mechanisms, components, and parts for which no specific structure is described are existing structures that already exist in the prior art and can be directly purchased from the market.

[0051] The above are only the preferred implementation schemes of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
