Description

Technical Field

[0001] This utility model relates to the field of structural reinforcement technology, and in particular to a crane slewing bearing reinforcement structure. Background Technology

[0002] During the operation of a crane, the slewing bearing plays an important role in its rotation, providing stable rotational force. In the process of using the slewing bearing, it is necessary to strengthen and stabilize it in conjunction with structures such as a base.

[0003] In practical applications, the existing slewing bearing reinforcement structures are relatively complete in structure and function, and can basically meet daily usage needs. However, the following problems still exist:

[0004] In actual use, during the rotation of the slewing bearing, the inner ring of the bearing is prone to misalignment or movement with the outer ring due to excessive external force, which can cause the inner ring to dislodge and affect the overall safety.

[0005] Therefore, this utility model provides a reinforced structure for the slewing bearing of a crane. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a reinforced structure for crane slewing bearings.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a crane slewing bearing reinforcement structure, comprising a base, an mounting groove on the inner wall of the base, a support outer ring inserted into the inner wall of the mounting groove, a support inner ring on the inner wall of the support outer ring, and a ball bearing between the support outer ring and the support inner ring; a reinforcing guide structure between the base and the support inner ring, the reinforcing guide structure comprising a connecting plate, one side of the connecting plate being fixedly connected to the outer surface of the base, and the other side of the connecting plate being fixedly connected to a support ring plate; an auxiliary disassembly and assembly structure between the base and the support outer ring, the auxiliary disassembly and assembly structure comprising a fixing ring plate, the bottom of the outer surface of the fixing ring plate being fixedly connected to the top of the support outer ring, a first threaded locking hole on the inner wall of the fixing ring plate, a second threaded locking hole on the top of the base, and threaded locking rods threadedly connected to the inner walls of the first threaded locking hole and the second threaded locking hole.

[0008] In a preferred embodiment, an annular groove is formed on the bottom of the outer surface of the support ring plate, a sliding rod is slidably connected to the inner wall of the annular groove, a rectangular auxiliary plate is fixedly connected to the bottom end of the sliding rod, a first screw hole is formed on the inner wall of the rectangular auxiliary plate, a second screw hole is formed at the bottom of the inner ring of the support, and a threaded locking rod is threadedly connected to the inner wall of the first screw hole and the second screw hole.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded locking rod, it can cooperate with the first threaded hole and the second threaded hole, thereby enabling the rectangular auxiliary plate and the inner ring of the support to be disassembled and assembled. In turn, the inner ring of the support can drive the sliding rod to slide on the inner wall of the annular groove during rotation, thereby enabling the inner ring of the support to be limited and guided.

[0010] In a preferred embodiment, a rectangular connecting block is fixedly connected to the outer surface of the support ring plate, and a support rod is fixedly connected to the bottom of the rectangular connecting block.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular connecting block and the support rod, the support ring plate and other components are prevented from fitting too tightly with the bottom components, thus avoiding contact and causing excessive friction due to mutual friction between the rectangular auxiliary plate and other components during rotation.

[0012] In a preferred embodiment, a round insert rod is fixedly connected to the bottom of the outer surface of the fixed ring plate, a round insert hole is opened at the top of the base, a threaded hole is opened at the bottom end of the round insert rod, a threaded rod is threadedly connected to the inner wall of the threaded hole, and a round stop block is fixedly connected to the bottom end of the threaded rod.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the round insert rod and the round insert hole, the first threaded locking hole and the second threaded locking hole can be quickly aligned, thereby facilitating the fixing of the threaded locking rod.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a reinforced guide structure, the inner support ring can rotate along the annular groove, driving the rectangular auxiliary plate and sliding rod to rotate during rotation. This provides auxiliary guidance and connection limit for the inner support ring, preventing it from easily becoming misaligned or detached from the outer support ring. This improves the overall safety of the inner support ring and allows for easy disassembly and maintenance. The auxiliary disassembly and assembly structure, with the help of the round insert rod and round hole, allows the first and second threaded locking holes to align quickly, facilitating the fixing of the threaded locking rod and making overall disassembly and assembly more convenient and faster.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4As shown, this embodiment provides a technical solution: a crane slewing bearing reinforcement structure, including a base 1, an mounting groove 7 on the inner wall of the base 1, a support outer ring 2 inserted into the inner wall of the mounting groove 7, a support inner ring 3 on the inner wall of the support outer ring 2, and a ball bearing 6 between the support outer ring 2 and the support inner ring 3; a reinforcing guide structure 4 is provided between the base 1 and the support inner ring 3, the reinforcing guide structure 4 including a connecting plate 41, one side of the connecting plate 41 being fixedly connected to the outer surface of the base 1, and the other side of the connecting plate 41 being fixedly connected to a support ring plate 42; an auxiliary disassembly and assembly structure 5 is provided between the base 1 and the support outer ring 2, the auxiliary disassembly and assembly structure 5 including a fixing ring plate 51, the bottom of the outer surface of the fixing ring plate 51 being fixedly connected to the top of the support outer ring 2, a first threaded locking hole 52 on the inner wall of the fixing ring plate 51, and a second threaded locking hole 52 on the top of the base 1. The inner walls of the two threaded locking holes 53, the first threaded locking hole 52, and the second threaded locking hole 53 are threadedly connected to threaded locking rods 54. By setting a reinforced guide structure 4, the inner ring of the support can rotate along the annular groove 43 during rotation, thereby providing auxiliary guidance and connection limit for the inner ring of the support, preventing it from easily becoming misaligned or disengaged from the outer ring of the support, thus improving the overall safety of the inner ring of the support and allowing for easy disassembly and maintenance. By setting an auxiliary disassembly and assembly structure 5, the first threaded locking hole 52 and the second threaded locking hole 53 can be quickly aligned under the action of the round insertion rod 55 and the round insertion hole 59, facilitating the fixing of the threaded locking rod 54 and making the overall disassembly and assembly more convenient and quick.

[0027] Going further, such as Figures 2-4 As shown: An annular groove 43 is provided at the bottom of the outer surface of the support ring plate 42. A sliding rod 44 is slidably connected to the inner wall of the annular groove 43. A rectangular auxiliary plate 45 is fixedly connected to the bottom end of the sliding rod 44. A first screw hole 46 is provided on the inner wall of the rectangular auxiliary plate 45. A second screw hole 48 is provided at the bottom of the support inner ring 3. A threaded locking rod 47 is threadedly connected to the inner wall of the first screw hole 46 and the second screw hole 48. Under the action of the threaded locking rod 47, it can cooperate with the first screw hole 46 and the second screw hole 48, thereby allowing the rectangular auxiliary plate 45 and the support inner ring 3 to be disassembled and assembled. Thus, during the rotation of the support inner ring 3, the sliding rod 44 can be driven to slide on the inner wall of the annular groove 43, thereby limiting and guiding the support inner ring 3.

[0028] The above solutions also have the problem that the support ring plate 42 is too close to the bottom structure, which easily increases friction when the rectangular auxiliary plate 45 rotates. Figure 4As shown: In this solution, a rectangular connecting block 49 is fixedly connected to the outer surface of the support ring plate 42, and a support rod 410 is fixedly connected to the bottom of the rectangular connecting block 49. Under the action of the rectangular connecting block 49 and the support rod 410, the support ring plate 42 and other components are prevented from fitting too tightly with the bottom components, thus avoiding contact and causing excessive friction due to mutual friction between the rectangular auxiliary plate 45 and other components during rotation.

[0029] The above solution also has the problem that the first threaded locking hole 52 and the second threaded locking hole 53 need to be manually aligned, which is very time-consuming. Figure 3 and Figure 4 As shown, a round insert rod 55 is fixedly connected to the bottom of the outer surface of the fixed ring plate 51. A round insert hole 59 is opened at the top of the base 1. A threaded hole 56 is opened at the bottom end of the round insert rod 55. A threaded rod 57 is threadedly connected to the inner wall of the threaded hole 56. A round stop block 58 is fixedly connected to the bottom end of the threaded rod 57. Under the action of the round insert rod 55 and the round insert hole 59, the first threaded locking hole 52 and the second threaded locking hole 53 can be quickly aligned, thereby facilitating the fixing of the threaded locking rod 54.

[0030] Working principle:

[0031] like Figure 1-4 As shown:

[0032] When in use: the outer ring 2 of the support is engaged with the mounting groove 7. At this time, the round insert rod 55 can be inserted into the inner wall of the round insert hole 59. At this time, the first threaded locking hole 52 and the second threaded locking hole 53 are aligned, and the threaded locking rod 54 can be fixed with the first threaded locking hole 52 and the second threaded locking hole 53.

[0033] At this time, the threaded rod 57 is fixed to the threaded hole 56, so that the round stop block 58 can assist in limiting the round insert rod 55.

[0034] At this time, the threaded locking rod 47 is fixed to the first threaded hole 46 and the second threaded hole 48. When the inner ring 3 of the support rotates, it can drive the rectangular auxiliary plate 45 to rotate, thereby causing the sliding rod 44 to slide on the inner wall of the annular groove 43.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
