[0046] Embodiment 1

[0047] See also Figure 1 and Figure 2 A slewing bearing connector 1 provided in this embodiment is applied to a crane to realize the installation of a slewing bearing 2 of the crane and a slewing table (not shown).

[0048] Specifically, the slewing bearing connector 1 provided in this embodiment includes at least two connector bodies 10, the shape of the connector body 10 is adapted to the shape of the outer ring 2b of the slewing bearing 2, that is, it is in an arc shape, and the central angle of the connector body 10 is less than or equal to 180°.

[0049] It is understandable that, since the outer ring 2b of the slewing bearing 2 is in the shape of a ring, wherein the connector body 10 is a half ring or a section of an arc smaller than a half ring, in order to ensure the stability of the connection of the slewing bearing 2, the connector body 10 needs to be used in pairs at least.

[0050] In this embodiment, two connector bodies 10 are selected and designed. The connector body 10 is described one by one below. The central angle of the connector body 10 is less than 180°. Under the premise of ensuring the stable installation of the slewing bearing 2, the material cost is saved and the processing difficulty is reduced.

[0051] In some specific embodiments, the central angle of the connector body 10 is 90° to 175°.

[0052] Furthermore, in some other specific embodiments, the central angle of the connector body 10 is 100° to 165°.

[0053] In some other specific embodiments, the central angle of the connector body 10 is selected to be one of 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, and 160°. The above are only examples for illustration and are not intended to limit the scope of protection of the present invention.

[0054] Combined with reference Figure 3 , Figure 4 as well as Figure 5 The connector body 10 includes a first connecting plate 102, a second connecting plate 103 and a supporting rib 105. The first connecting plate 102 and the second connecting plate 103 are arranged opposite to each other, that is, they are arranged opposite to each other up and down in this embodiment. The supporting rib 105 is supported between the first connecting plate 102 and the second connecting plate 103 and is connected to the first connecting plate 102 and the second connecting plate 103.

[0055] In this embodiment, it can be understood that the first connecting plate 102 and the second connecting plate 103 are arc-shaped plates, which are arranged in parallel up and down to ensure that the connector body 10 is in an arc shape as a whole. Further, the surface of the first connecting plate 102 facing away from the second connecting plate 103 is a fan-shaped mounting surface, and similarly, the surface of the second connecting plate 103 facing away from the first connecting plate 102 is also a fan-shaped mounting surface.

[0056] Therefore, if Figure 5 As shown, through the above structure, the cross section of the connector body 10 along the width direction is I-shaped. The connector body 10 with an I-shaped structure has better mechanical properties, such as strength and bending resistance, and can better support the weight brought by the slewing bearing 2.

[0057] Furthermore, it can be understood that in the connector body 10 of the I-shaped structure, the supporting ribs 105 are located in the middle of the first connecting plate 102 and the middle of the second connecting plate 103 .

[0058] Combined with reference Figure 6The support rib plate 105 is a whole arc-shaped plate, and the support rib plate 105 has an inner arc side 105a and an opposite outer arc side 105b. The inner arc side 105a of the support rib plate 105, together with the first connecting plate 102 and the second connecting plate 103, encloses a first chamber 100a, and the outer arc side 105b of the support rib plate 105, together with the first connecting plate 102 and the second connecting plate 103, encloses a second chamber 100b.

[0059] In some specific embodiments, the first connecting plate 102, the second connecting plate 103 and the supporting rib plate 105 in the connector body 10 are an integrally formed structure. Of course, the first connecting plate 102, the second connecting plate 103 and the supporting rib plate 105 can also be formed by welding.

[0060] In some other specific embodiments, the connector body 10 can directly use H-shaped steel of national standard, that is, I-beam.

[0061] In this embodiment, in order to strengthen the structural strength of the connector body 10 and improve the compression and bending resistance of the connector body 10, a predetermined number of reinforcing ribs 106 are arranged in the first chamber 100a and the second chamber 100b. These reinforcing ribs 106 are supported between the first connecting plate 102 and the second connecting plate 103 and are welded together with the first connecting plate 102 and the second connecting plate 103.

[0062] In some specific embodiments, the reinforcing rib plate 106 is only provided in the first chamber 100a, or the reinforcing rib plate 106 is only provided in the second chamber 100b. These two structural schemes can also be implemented, but are not as stable as the structure in which the reinforcing rib plates 106 are provided in both the first chamber 100a and the second chamber 100b.

[0063] Furthermore, the reinforcing ribs 106 in the first chamber 100a and the second chamber 100b are arranged at equal intervals. In other words, the reinforcing ribs 106 divide the first chamber 100a and the second chamber 100b into multiple small chambers of predetermined sizes, so as to ensure that the first connecting plate 102 and the second connecting plate 103 are more stably stressed, thereby further strengthening the structural strength of the connector body 10.

[0064] For better distinction and understanding, this embodiment defines the fan-shaped mounting surface on the first connecting plate 102 as the first fan-shaped mounting surface 102a, and the fan-shaped mounting surface on the second connecting plate 103 as the second fan-shaped mounting surface 103a, and the first fan-shaped mounting surface 102a and the second fan-shaped mounting surface 103a are arranged opposite to each other.

[0065] Among them, a predetermined number of assembly holes 100 are provided on the first fan annular mounting surface 102a, and a predetermined number of assembly holes 100 are also provided on the second fan annular mounting surface 103a, and the assembly holes 100 on the first fan annular mounting surface 102a pass through the first connecting plate 102 and the assembly holes 100 on the second fan annular mounting surface 103a pass through the second connecting plate 103. It can be seen that the first connecting plate 102 and the second connecting plate 103 both have the function of connection.

[0066] In some specific embodiments, the first connecting plate 102 can be used to connect the slewing bearing 2 or to connect the turntable, and at the same time, the second connecting plate 103 can be used to connect the slewing bearing 2 or to connect the turntable. The purpose of this design is to ensure that the connector body 10 does not need to distinguish between the front and back when in use, which is more convenient to use and can save steps in processing.

[0067] In this embodiment, an example is given in which the first connecting plate 102 is used to install the slewing bearing 2 and the second connecting plate 103 is used to connect the slewing table.

[0068] Since the structures of the slewing bearing 2 and the turntable are different, and the width of the turntable is smaller than the diameter of the slewing bearing 2, after the traditional slewing bearing 2 is installed on the turntable, the slewing bearing 2 cannot be completely in contact with the turntable, but a part of the slewing bearing 2 extends out of the turntable.

[0069] Based on the above reasons, in order to adapt to the standard production of the slewing bearing 2 and the slewing table, the number of the assembly holes 100 opened on the first sector annular mounting surface 102a should correspond to the number of the assembly holes 100 on the outer ring 2b of the slewing bearing 2, and the number of the assembly holes 100 opened on the second sector annular mounting surface 103a should correspond to the number of the assembly holes 100 on the slewing table. It can be understood that the assembly holes 100 on the first sector annular mounting surface 102a are arranged along the arc length of the first connecting plate 102, and the assembly holes 100 on the second sector annular mounting surface 103a are concentrated in the middle of the second connecting plate 103.

[0070] It can be understood that the assembly hole 100 provided on the first connecting plate 102 penetrates into the first chamber 100a, and the purpose of such arrangement is that the first connecting plate 102 will not interfere with the rotation of the inner ring 2a of the slewing bearing 2 when connecting the outer ring 2b of the slewing bearing 2. The assembly hole 100 provided on the second connecting plate 103 partially penetrates into the first chamber 100a, and the other part can also penetrate into the second chamber 100b.

[0071] Furthermore, in order to ensure the stability of the slewing bearing 2 after installation, the first annular installation surface 102a and the second annular installation surface 103a need to be polished, which can be done manually with a grinding machine or machined with CNC equipment.

[0072] Considering that the workload of manual grinding is too large, the labor intensity is increased, and it is not suitable for mass production, this embodiment adopts CNC equipment for processing, specifically, a milling machine is used to perform a first-level milling process on the first fan annular mounting surface 102a and the second fan annular mounting surface 103a, and then a grinder or manual secondary fine processing is performed to ensure the flatness and roughness of the first fan annular mounting surface 102a and the second fan annular mounting surface 103a, so as to effectively avoid the problem of instability of the slewing bearing 2 after installation.

[0073] When in use, the fastener 3 passes through the assembly hole 100 of the first connecting plate 102 and the assembly hole 100 on the outer ring 2b of the slewing bearing 2, that is, the connection of the slewing bearing 2 is realized. The fastener 3 passes through the assembly hole 100 of the second connecting plate 103 and the assembly hole 100 on the turntable, that is, the connection of the connector body 10 and the turntable is realized.

[0074] In this embodiment, the fastener 3 is a bolt assembly, which includes a bolt and a nut. Furthermore, the bolt can also be replaced by a double-headed screw.

[0075] Therefore, the arrangement of the first chamber 100a and the second chamber 100b can facilitate the tool to tighten the nut. At the same time, it can be understood that the arrangement of the reinforcing rib plate 106 should not interfere with the movement of the tool.

[0076] The slewing bearing connector 1 provided in this embodiment realizes the transition connection between the slewing bearing 2 and the turntable through the connector body 10. Therefore, under the premise of not changing the sizes of the slewing bearing 2 and the turntable, by changing the diameter and position of the assembly holes 100 on the first connecting plate 102 and the second connecting plate 103 in the connector body 10, the connection between different slewing bearings 2 and different turntables can be realized, which is flexible and convenient and does not affect the standardized production of the slewing bearing 2 and the turntable.

[0077] In addition, in the prior art, the slewing bearing 2 and the turntable are directly connected by bolts. However, threaded holes are processed on the turntable, and the thread strength is not completely reliable. In contrast, this embodiment uses a combination of bolts and nuts to connect the slewing bearing 2 and the turntable, thereby obtaining excellent connection strength and reliability.

[0078] Embodiment 2

[0079] See also Figure 1-Figure 7 This embodiment provides a slewing bearing connector 1, which is a further improvement on the above embodiment 1. The main difference compared with the above embodiment 1 is:

[0080] Please refer to Figure 7In the present embodiment, the support rib 105 has a Z-shaped coiled structure. It can be understood that the support rib 105 is supported between the first connecting plate 102 and the second connecting plate 103 in a Z-shaped coiled manner, or can also be supported between the first connecting plate 102 and the second connecting plate 103 in an S-shaped coiled manner.

[0081] This embodiment is supported on the first connecting plate 102 and the second connecting plate 103 by Z-shaped winding. Compared with the first embodiment, it is not necessary to add the reinforcing rib plate 106, and the effect of adding the reinforcing rib plate 106 in the first embodiment can be achieved.

[0082] Embodiment 3

[0083] See also Figure 1-Figure 7 This embodiment provides a slewing bearing connector 1, which is a further improvement on the basis of the above-mentioned embodiment 1 or embodiment 2. The main difference between the above-mentioned embodiment 1 or embodiment 2 is:

[0084] For details, please refer to Figure 3 , Figure 4 as well as Figure 5 In the present embodiment, considering that the thickness of the first connecting plate 102 and the second connecting plate 103 is limited, if the first connecting plate 102 and the second connecting plate 103 are directly milled, the thickness of the first connecting plate 102 and the second connecting plate 103 will be smaller, thereby reducing the strength of the first connecting plate 102 and the second connecting plate 103.

[0085] Furthermore, the connector body 10 also includes a first flange reinforcement plate 101 and a second flange reinforcement plate 104, wherein the first flange reinforcement plate 101 is arranged on the first fan-annular mounting surface 102a of the first connecting plate 102, and is used to improve the structural rigidity and reinforcement of the first connecting plate 102, and the second flange reinforcement plate 104 is arranged on the second fan-annular mounting surface 103a of the second connecting plate 103, and is used to improve the structural rigidity and reinforcement of the second connecting plate 103.

[0086] Further, the first flange reinforcement plate 101 covers the area on the first fan annular mounting surface 102a where the assembly hole 100 is provided, and the second flange reinforcement plate 104 covers the area on the second fan annular mounting surface 103a where the assembly hole 100 is provided. It can be understood that the central angle of the first flange reinforcement plate 101 is greater than the central angle of the second flange reinforcement plate 104, and the purpose of such arrangement in this embodiment is to save the cost of material investment.

[0087] In this embodiment, both sides of the first flange reinforcement plate 101 and the second flange reinforcement plate 104 can be milled to ensure that both sides of the first flange reinforcement plate 101 and the second flange reinforcement plate 104 are smooth and flat surfaces. In this way, the first connecting plate 102 and the second connecting plate 103 are not milled, and the mechanical structure performance of the first connecting plate 102 and the second connecting plate 103 is ensured.

[0088] Furthermore, the milled first flange reinforcement plate 101 is welded to the first fan-shaped annular mounting surface 102a of the first connecting plate 102, and the second flange reinforcement plate 104 is welded to the second fan-shaped annular mounting surface 103a of the second connecting plate 103, that is, the first flange reinforcement plate 101 and the second flange reinforcement plate 104 are both welded to the connector body 10 to form an integrated structure.

[0089] Finally, the first through hole 101a is processed in the first flange reinforcement plate 101, and the second through hole 104a is processed in the second flange reinforcement plate 104, so that it can be ensured that the first through hole 101a corresponds to the assembly hole 100 on the first connecting plate 102 one by one, and the second through hole 104a corresponds to the assembly hole 100 on the second connecting plate 103 one by one.

[0090] In some specific embodiments, after the first flange reinforcement plate 101 is welded to the first fan-annular mounting surface 102a of the first connecting plate 102 and the second flange reinforcement plate 104 is welded to the second fan-annular mounting surface 103a of the second connecting plate 103, the first through hole 101a and the assembly hole 100 on the first connecting plate 102 are processed together, and the second through hole 104a and the assembly hole 100 on the second connecting plate 103 are processed together to ensure that the first through hole 101a corresponds one-to-one with the assembly hole 100 on the first connecting plate 102, and the second through hole 104a corresponds one-to-one with the assembly hole 100 on the second connecting plate 103.

[0091] In some other specific embodiments, after the first flange reinforcement plate 101 is welded to the first fan-annular mounting surface 102a of the first connecting plate 102 and the second flange reinforcement plate 104 is welded to the second fan-annular mounting surface 103a of the second connecting plate 103, the first flange reinforcement plate 101 and the second flange reinforcement plate 104 are processed by a milling machine, and then the first through hole 101a and the assembly hole 100 on the first connecting plate 102 are processed together, and the second through hole 104a and the assembly hole 100 on the second connecting plate 103 are processed together.

[0092] The slewing bearing connector 1 provided in this embodiment has the same advantages as those of the first or second embodiment described above, and at the same time ensures that the structural rigidity and reinforcement of the first connecting plate 102 and the second connecting plate 103 are improved without changing the mechanical structural performance of the first connecting plate 102 and the second connecting plate 103.
