Description

Technical Field

[0001] This application belongs to the field of flipping device manufacturing, specifically a flipping device for installing heavy rolling bearing housings. Background Technology

[0002] Unlike sliding bearing housings, rolling bearing housings cannot be split into two halves, making installation more difficult, especially for heavy-duty compressors. The impeller weighs over 1 ton and has a cantilever beam structure. When made into a rigid rotor, the entire rotor is very heavy. It is difficult to install the bearing housing horizontally, and it is also difficult to turn it over when installed vertically. This invention solves the problem of vertical installation and turning over. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a flipping device for installing heavy-duty rolling bearing seats, which uses a rotating frame mounted on a mounting frame and a telescopic rod. The telescopic rod drives the rotating frame to rotate, thereby turning the rolling bearing seats mounted on the rotating frame from a horizontal state to a vertical state, thus solving the problem of how to flip the seats for vertical installation.

One end of the telescopic rod is rotatably connected to the mounting frame. The projection of the connection point between the telescopic rod and the mounting frame on the base frame is located on the projection of the end of the mounting frame facing away from the center of gravity of the base frame on the base frame. The other end of the telescopic rod is rotatably connected to the rotating frame. The mounting frame is provided with a fixing device for fixing the heavy-duty rolling bearing housing. The length and width of the base frame are at least fifty times greater than the height of the base frame.

[0008] Preferably, a support block is provided on the lower surface of the rotating frame at the end away from the connecting block, near the front and rear side walls, and a rubber pad is provided on the lower surface of the support block.

[0009] Preferably, the connection between the telescopic rod and the rotating frame is located on the perpendicular bisector of the connecting line segment between the two connecting blocks.

[0019] like Figure 1-4As shown, a flipping device for installing a heavy-duty rolling bearing housing includes a mounting frame 1, a rotating frame 2, and a base frame 3. The mounting frame 1 is disposed on the upper surface of the base frame 3, and the mounting frame 1 is located on one side of the center of gravity of the base frame 3. The rotating frame 2 is rotatably disposed on the upper surface of the mounting frame 1. The mounting frame 1 is provided with a telescopic rod 4. One end of the telescopic rod 4 is rotatably connected to the mounting frame 1. The projection of the connection point between the telescopic rod 4 and the mounting frame 1 on the base frame 3 is located on the projection of the end of the mounting frame 1 facing away from the center of gravity of the base frame 3 on the base frame 3. The other end of the telescopic rod 4 is rotatably connected to the rotating frame 2. The mounting frame 1 is provided with a fixing device for fixing the heavy-duty rolling bearing housing. The length and width of the base frame 3 are at least fifty times greater than the height of the base frame 3.

[0020] In this embodiment, during use, the heavy-duty rolling bearing seat is placed on the rotating frame 2, which is initially parallel to the mounting frame 1. The heavy-duty rolling bearing seat is then fixed to the rotating frame 2 using a fixing device. The telescopic rod 4 is then extended, causing the rotating frame 2 to rotate on the mounting frame 1, thereby allowing the heavy-duty rolling bearing seat to rotate from a horizontal position to a vertical position. The projection of the connection point between the telescopic rod 4 and the mounting frame 1 onto the base frame 3, with the projection of the end of the mounting frame 1 facing away from the center of gravity of the base frame 3 onto the base frame 3, is designed to prevent the entire tilting device from tipping over during the process of the heavy-duty rolling bearing seat being erected. The fact that the length and width of the base frame 3 are at least fifty times greater than its height further ensures that the entire tilting device will not tip over during the process of the heavy-duty rolling bearing seat being erected.

[0021] As a preferred embodiment, both the mounting bracket 1 and the rotating bracket 2 are welded from square tubing and sheet metal. This simplifies the manufacturing process, facilitates its widespread adoption, and utilizes conventional materials, thus reducing manufacturing costs.

[0022] As a preferred embodiment, the upper surface of the mounting bracket 1 has two mounting blocks 5 at its left end. The connecting line between the two mounting blocks 5 is parallel to the left side wall of the mounting bracket 1. Each of the two mounting blocks 5 has a through hole 6, which are coaxial. The lower surface of the rotating bracket 2 has a connecting block 7 near the front and rear side walls. Each connecting block 7 has a pin 8, which is coaxially and rotatably connected to one of the through holes 6. With this design and arrangement, when the rotating bracket 2 is lifted by the telescopic rod 4, it rotates around the pin 8. The mounting blocks 5 and connecting blocks 7 are used to mount the pin 8.

[0023] As a preferred embodiment, a support block 9 is provided on the lower surface of the rotating frame 2 at the end away from the connecting block 7, near the front and rear side walls. A rubber pad 10 is provided on the lower surface of the support block 9. The support block 9 is provided so that when the rotating frame 2 is not rotating, the rotating frame 2 is parallel to the mounting frame 1, and the support block 9 is used to support the end of the rotating frame 2 facing away from the pin 8 when the rotating frame 2 is not rotating.

[0024] As a preferred embodiment, the connection between the telescopic rod 4 and the rotating frame 2 is located on the perpendicular bisector of the connecting line segment between the two connecting blocks 7. This arrangement ensures that the rotating frame 2 experiences uniform force when supported by the telescopic rod 4.

[0025] As a preferred embodiment, the fixing device includes a bolt 11 and a threaded hole, the threaded hole being located on the upper surface of the rotating frame 2. With this configuration, the heavy-duty rolling bearing seat can be directly locked with the bolt 11 after being placed on the rotating frame 2, which is relatively simple.

[0026] As a preferred embodiment, the telescopic rod 4 is a hydraulic telescopic rod. Hydraulic telescopic rods are more stable than pneumatic ones.
