Description

Technical Field

[0001] This invention relates to the field of bearing cage transport equipment, and particularly to an automatic folding transport bracket for large-size bearing cages. Background Technology

[0002] For bearing cages used in larger bearings, such as those in wind turbine bearings with a diameter greater than 3500mm, their size often makes them difficult to place flat on a transport vehicle. Therefore, bearing cages are usually placed at an angle during transport. Currently, these bearing cages are typically secured using specialized transport supports. Existing transport supports include a chassis and a support section mounted on the chassis. The bearing cage is placed at an angle on the support section to reduce its lateral dimensions. However, these existing transport supports are fixed structures, occupying a significant amount of space and making them difficult to operate when storing or transferring them. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an automatic folding transport bracket for large-size bearing cages. This bracket can automatically fold when idle, facilitating transport and storage. During use, the rear support can automatically extend, allowing the bearing cage to tilt, thus reducing the horizontal dimensions of the bearing cage and the entire transport bracket. This effectively solves the problems existing in the prior art.

[0004] To address the aforementioned problems, this invention provides an automatic folding transport bracket for large-size bearing cages, comprising: a chassis; a tray assembly disposed on the upper side of the chassis, including a tray body and a plurality of fixing members for fixing the bearing cage, the fixing members being disposed around an axis on the tray body; and a support assembly including a front support portion and a rear support portion, wherein the upper end of the front support portion is hinged to the tray body and the lower end is connected to the chassis, the upper end of the rear support portion is hinged to the tray body and the lower end is hinged to the chassis, the rear support portion being an automatically lifting and lowering rear support portion, and the tray body being able to rotate around the upper end of the front support portion when the rear support portion extends and retracts.

[0005] Furthermore, the rear support includes a scissor lift rod and an electric unit that drives the scissor lift rod to rise and fall.

[0006] Furthermore, the transport bracket also includes a guide rod disposed on one side of the rear support portion. The upper end of the guide rod is hinged to the disc body and the lower end is hinged to the chassis. The guide rod is telescopically oriented, and the rear support portion can drive the guide rod to telescopically extend and retract when it is raised or lowered.

[0007] Furthermore, the guide rod includes several sleeves inserted sequentially, and there are two guide rods in total, with the two guide rods respectively disposed on both sides of the rear support portion.

[0008] Furthermore, the front support includes a scissor lift rod and an electric unit that drives the scissor lift rod to rise and fall; a guide rod is provided on each side of the front support, and the guide rod includes a plurality of sleeves that are connected in sequence.

[0009] Furthermore, the disc body includes N support rods circumferentially spaced around the axis, and movable rods slidably connected to the support rods, with each of the fixing members respectively disposed at the outer end of the movable rod.

[0010] Furthermore, the support rod is hollow, the movable rod is slidably inserted into the support rod, the support rod is provided with a fixing hole, the movable rod is provided with a positioning hole, and the transport bracket also includes a pin that passes through the fixing hole and the positioning hole.

[0011] Furthermore, the fixing member is disposed at the outer end of the movable rod, and the fixing member includes two spaced fixing posts.

[0021] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0022] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two connected entities do not establish a connection relationship through an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0025] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] In this invention, such as Figure 1-4 As shown, an automatic folding transport bracket for a large-size bearing cage 18 is provided, comprising: a chassis 1; a tray assembly disposed on the upper side of the chassis 1, including a tray body 2 and a plurality of fixing members for fixing the bearing cage 18, the fixing members being disposed around an axis 19 on the tray body 2; and a support assembly including a front support part 3 and a rear support part 4, wherein the upper end of the front support part 3 is hinged to the tray body 2 and the lower end is connected to the chassis 1, the upper end of the rear support part 4 is hinged to the tray body 2 and the lower end is hinged to the chassis 1, the rear support part 4 is an automatically lifting and lowering rear support part 4, and when the rear support part 4 is lifted and lowered, the tray body 2 can rotate around the upper end of the front support part 3.

[0027] In use, the transport bracket of the present invention fixes the bearing retainer 18 with a fastener, making the axis of the bearing retainer 18 substantially parallel to the axis 19 of the fastener. The rear support portion 4 extends out, allowing the disc 2 to rotate upwards around the upper end of the first support portion, causing the disc 2 to tilt. This reduces the overall horizontal dimensions of the transport bracket and bearing retainer 18, facilitating transport. When the transport bracket is idle, the rear support portion 4 retracts, causing the disc 2 to rotate downwards around the top of the first support rod 201, reducing the overall height of the transport bracket. This allows for stacking of transport brackets, reducing the space occupied during transport and storage.

[0028] Therefore, the transport bracket of the present invention can tilt and lift the bearing retainer 18 when transporting it, and can be folded when the transport bracket is not in use, reducing the space occupied by the transport bracket during transportation and storage. Moreover, the folding and unfolding of the transport bracket can be completed automatically, making it convenient to use.

[0029] It should be noted that, in Figure 1 In the illustrated embodiment, the rear support 4 includes a scissor lift 5 and an electric unit 6 that drives the scissor lift 5 to rise and fall. Figure 3 As shown, the rear support rod 201 adopts a scissor-type lifting rod 5, which enables the rear support part 4 to be raised and lowered significantly, thereby increasing the rotation angle range of the disc body 2 and meeting transportation needs. Moreover, the scissor-type lifting rod 5 is driven by an electric unit 6, and can be raised and lowered by a small battery during use, making it convenient to use.

[0030] It should be noted that the electric unit 6 referred to in this invention can be an electric telescopic rod. When the telescopic rod drives the lifting rod to rise and fall during inspection, the existing scissor lift structure can be used, which will not be described in detail here.

[0031] Regarding the configuration of the rear support part 4, in addition to the scissor lift structure, other types of lift structures can also be used. For example, the rear support part 4 can directly adopt a telescopic rod.

[0032] Furthermore, the power element in the rear support 4 can be either an electric element or, in alternative embodiments, a pneumatic element.

[0033] for Figure 1 In the illustrated embodiment, a further optimization is that the transport bracket also includes a guide rod 7 disposed on one side of the rear support portion 4. The upper end of the guide rod 7 is hinged to the disc body 2, and the lower end is hinged to the chassis 1. The guide rod 7 is telescopic, and the rear support portion 4 can drive the guide rod 7 to extend or retract during lifting and lowering. This prevents the disc body 2 from moving relative to the chassis 1 in the horizontal direction, improving the stability of the disc body 2.

[0034] Specifically, regarding the arrangement of the guide rod 7, the guide rod 7 comprises several sleeves 701 inserted sequentially, and there are two guide rods 7 in total, with the two guide rods 7 respectively located on both sides of the rear support portion 4. Figure 3 As shown, by setting the first guide rod 7 on each side of the rear support part 4, the limiting force on the disc body 2 can be made more uniform.

[0035] A further optimization is that the front support part 3 includes a scissor lift rod 5 and an electric unit 6 that drives the scissor lift rod 5 to rise and fall; a guide rod 7 is provided on each side of the front support part 3, and the guide rod 7 includes a plurality of sleeves 701 that are sequentially connected. Figure 2 As shown, with this configuration, when the transport bracket is idle, the front support 3 can be lowered to its lowest position, which can further reduce the height of the disc body 2, and thus further reduce the height of the entire transport bracket.

[0036] The scissor lift 5 used in the front support part 3 has the same structure as the scissor lift 5 used in the rear support part 4.

[0037] A further optimization is that the disc body 2 includes N circumferentially spaced support rods 201 arranged around the axis 19, and movable rods 202 slidably connected to the support rods 201, with each fixing member respectively disposed at the outer end of the movable rod 202. For example... Figure 1 As shown, with this configuration, the distance between the fixed part and the axis 19 can be adjusted by sliding the movable rod 202, thus making it suitable for transporting bearing cages 18 with different radial dimensions. Moreover, when the transport bracket is idle, the movable rod 202 can be slid inward to retract it, thereby reducing the overall profile of the transport bracket and facilitating transportation and storage.

[0038] More specifically, the support rod 201 is hollow, the movable rod 202 is slidably inserted into the support rod 201, the support rod 201 is provided with a fixing hole 8, the movable rod 202 is provided with a positioning hole 9, and the transport bracket also includes a pin 10 passing through the fixing hole 8 and the positioning hole 9.

[0039] More specifically, the fixing member is disposed at the outer end of the movable rod 202. The fixing member includes two spaced-apart fixing posts 11. The two fixing posts 11 are arranged at intervals along the extension direction of the movable rod 202, and the extension direction of the two fixing posts 11 is parallel to the axis 19. The two fixing posts 11 clamp the bearing retainer 18. Figure 4As shown, when the transport bracket is in use, the fixed column is rotated to the working state, and the gap formed between the two fixed columns can accommodate the bearing retainer 18. Moreover, multiple bearing retainers 18 can be stacked at the same time. Furthermore, when the transport bracket is idle, the movable rod 202 can be pulled out. At this time, the movable rod 202 and the fixing member can be placed separately, or the movable rod 202 can be flipped so that the fixed column 11 faces downward, thereby further reducing the height of the entire disc 2.

[0040] A further optimization is that one of the fixed columns 11 is fixedly connected to the movable rod 202, and the lower end of the other fixed column 11 is provided with a connecting plate 12. The connecting plate 12 has a waist hole 13 extending along the length direction of the movable rod 202, and a mounting hole 14 is provided on the movable rod 202. The transport bracket also includes a bolt 15, which clamps the connecting plate 12 with the movable rod 202. Figure 4 As shown, this allows for easy adjustment of the gap between the two fixed posts 11, thus making it suitable for bearing cages 18 of different specifications.

[0041] A further optimization is that the transport support also includes a fixing plate 16, on which two clamping holes 17 are formed for the fixing columns to pass through, and the fixing plate 16 restricts the relative movement of the two fixing columns. Figure 4 As shown, by setting it up in this way, the two fixing posts 11 can be prevented from moving relative to each other by the fixing plate 16 when transporting the bearing cage 18, thereby improving the stability of fixing the bearing cage 18.

[0042] It should be noted that, in Figure 1 , Figure 2 , Figure 3 In order to better demonstrate the structure of the present invention, the upper ends of the scissor lifts are not connected to the disc body, and the guide rods are also not connected to the disc body. This does not affect the implementation of the present invention.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0044] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
