Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, and in particular to a rotating shaft tooling and a gantry rotation system. Background Technology

[0002] In the field of construction machinery, especially in equipment involving gantry rotation systems, the shaft, as a core component connecting the fixed gantry and the rotating gantry, directly affects the reliability and maintenance efficiency of the equipment due to its installation stability, axial limiting capability, and ease of assembly and disassembly. Traditional shaft installation methods typically employ welding fixation, multi-bolt locking, or complex split structures, which present the following problems:

[0003] The traditional pivot requires a large number of bolts or welding to fix it to the gantry assembly, which makes the installation and disassembly process cumbersome and inefficient, especially in confined spaces or frequent maintenance scenarios.

[0004] Insufficient axial restraint means that some designs rely on shaft shoulders or additional restraints to prevent axial movement of the shaft. However, such structures are prone to loosening due to vibration or load changes and require complex processing techniques, which increases manufacturing costs.

[0005] Lock plate installation relies on the gantry. In the prior art, the lock plate is usually directly fixed around the shaft hole of the gantry assembly. This not only places higher demands on the structural strength of the gantry, but also limits the flexibility of the fit between the pivot and the gantry. Furthermore, the connection between the lock plate and the gantry must be handled simultaneously during disassembly, further increasing the complexity of the operation.

[0006] To address the aforementioned issues, there is an urgent need for a rotating shaft fixture that can simplify the installation process, reliably limit axial displacement, and reduce dependence on the gantry assembly structure. Summary of the Invention

[0007] To address the aforementioned problems, the present invention aims to provide a rotating shaft tooling and a gantry rotation system, which has the advantages of simplifying the installation process, reliably limiting axial displacement, and reducing dependence on the gantry component structure.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] This application provides a rotating shaft tooling, the technical solution of which is as follows: A rotating shaft tooling includes: a rotating shaft body, wherein a retaining ring is provided on the outer surface of its first end, the retaining ring protruding radially outward relative to the outer surface of the first end; a groove is formed inward on the outer surface of the second end of the rotating shaft body; a washer is sleeved on the first end of the rotating shaft body and located inside the annular groove of the retaining ring; the rotating shaft body between the washer and the retaining ring is used to pass through the shaft hole of a gantry assembly, the washer and the retaining ring are used to press against both sides of the shaft hole of the gantry assembly; a locking plate is fixedly connected to the washer and at least partially engaged in the groove of the second end of the rotating shaft body.

[0010] Furthermore, this application also proposes that the retaining ring is a circular retaining ring arranged circumferentially along the outer surface of the first end.

[0011] Furthermore, this application also proposes that the groove is an annular groove circumferentially disposed around the outer surface of the second end.

[0012] Furthermore, this application also proposes that the locking plate is two or more pieces, with multiple locking plates forming a ring structure, and its inner ring being embedded in the ring groove.

[0013] Furthermore, this application also proposes that the washer is provided with a threaded hole, and the locking plate is provided with a through hole; the fastening component passes through the through hole of the locking plate and is fixedly connected to the threaded hole of the washer.

[0014] Furthermore, this application also proposes that the interior of the rotating shaft body is constructed with an oil passage, the inlet of the oil passage is opened on the end face of the first end of the rotating shaft body, and the outlet of the oil passage is opened on the side of the rotating shaft body between the washer and the retaining ring.

[0015] Furthermore, this application also proposes a gantry rotation system, comprising: a fixed gantry; and a rotating gantry, which is mounted on the fixed gantry via the aforementioned rotating shaft fixture; wherein the rotating shaft body passes through the shaft holes of the fixed gantry and the rotating gantry, and the washers and retaining rings press against both sides of the shaft holes of the fixed gantry and the rotating gantry, respectively.

[0016] As can be seen from the above, the rotating shaft tooling and gantry rotation system provided in this application, through the combined pressing design of retaining ring and washer, and the fixed connection method of locking plate and washer, achieves quick disassembly and high stability without modifying the gantry component structure. At the same time, it significantly improves the system's maintenance convenience and adaptability, and has the advantages of simplifying the installation process, reliably limiting axial displacement, and reducing dependence on the gantry component structure.

[0025] Example 1:

[0026] like Figure 1 and 2 As shown, this embodiment proposes a rotating shaft fixture, including a rotating shaft body 1, a washer 4, and a locking plate 5. A retaining ring 2 is provided on the outer surface of the first end of the rotating shaft body 1, protruding radially outward relative to the outer surface of the first end; a groove 3 is formed concavely on the outer surface of the second end of the rotating shaft body 1. The washer 4 is fitted onto the first end of the rotating shaft body 1 and located inside the annular groove of the retaining ring 2; the rotating shaft body 1 between the washer 4 and the retaining ring 2 is used to pass through the shaft hole of the gantry assembly, and the washer 4 and the retaining ring 2 are used to press against both sides of the shaft hole of the gantry assembly. The locking plate 5 is fixedly connected to the washer 4 and is at least partially engaged in the groove 3 at the second end of the rotating shaft body 1. Through the combined design of the retaining ring 2, the washer 4, and the locking plate 5, this solution enables the rotating shaft fixture to achieve rapid assembly and disassembly with high stability without modifying the structure of the gantry assembly, significantly improving the system's maintenance convenience and adaptability. Specifically, the retaining ring 2 and the washer 4 press against both sides of the shaft hole of the gantry assembly to ensure stable installation of the rotating shaft; the locking plate 5 is fixed on the washer 4, and the locking plate 5 also engages in the groove 3 to form an axial lock, further restricting the axial movement of the rotating shaft. Thus, this technical solution solves the technical problems of installation stability, axial limiting capability, and ease of assembly and disassembly of the rotating shaft fixture in the gantry rotation system. Compared with existing technologies, it has higher installation efficiency and better maintenance convenience.

[0027] Furthermore, the retaining ring 2 is a circular retaining ring circumferentially arranged along the outer surface of the first end. Specifically, the retaining ring 2 is designed as a ring, and its shape perfectly matches the outer surface of the first end, ensuring that the retaining ring 2 can fit tightly against the outer surface of the shaft body 1. As a preferred embodiment, the retaining ring 2 can be directly fixed to the outer surface of the shaft body 1 by hot pressing or cold pressing, or fixed by welding, bolting, or integrally formed on the shaft body 1. In addition, the material of the retaining ring 2 can be high-strength alloy steel or stainless steel to improve its wear resistance and deformation resistance. In this regard, the retaining ring 2, as part of the shaft tooling, is designed as a circular retaining ring circumferentially arranged along the outer surface of the first end of the shaft body 1. This design ensures the stability and uniformity of the retaining ring 2 on the shaft body 1. Through this circumferential arrangement, the retaining ring 2 can effectively protrude radially outward, thereby providing a uniform pressing force between the shaft body 1 and the shaft hole of the gantry assembly, enhancing the axial limiting capability and installation stability of the shaft tooling. This design simplifies the structure of the rotating shaft tooling, improving its application efficiency and maintenance convenience in the field of engineering machinery. Therefore, the circular design of the retaining ring 2 not only solves the problems of inconvenient disassembly and insufficient axial limiting in traditional rotating shaft installation methods, but also reduces the dependence on the gantry assembly structure, achieving rapid disassembly and high stability.

[0028] Furthermore, the groove 3 is an annular groove circumferentially arranged around the outer surface of the second end. The annular groove can be formed by machining methods such as turning, milling, or casting, and its depth and width can be optimized according to the size and material properties of the locking plate 5. As a preferred embodiment, the depth of the annular groove is slightly less than the thickness of the locking plate 5 to ensure that the locking plate 5 can be partially embedded in the groove 3 while maintaining sufficient contact area to enhance connection stability. In addition, the cross-sectional shape of the annular groove can be rectangular, trapezoidal, or arc-shaped, and the specific shape can be adjusted according to the structure and installation requirements of the locking plate 5. Therefore, by providing an annular groove circumferentially on the outer surface of the second end of the shaft body 1, the locking plate 5 can be partially engaged in the groove 3, thereby significantly enhancing the connection stability between the locking plate 5 and the shaft body 1. This design not only simplifies the installation process of the locking plate 5 but also improves the overall structural strength of the shaft tooling. Compared with existing technologies, this solution does not rely on complex bolt connections or welding fixation, reducing the difficulty of disassembly and assembly, while avoiding connection loosening problems caused by vibration or load changes, effectively solving the technical problem of unstable connection between the locking plate 5 and the shaft body 1.

[0029] In a further embodiment, the locking plate 5 comprises two or more pieces, forming a ring structure, with its inner ring embedded in an annular groove. Specifically, the shape of the inner ring of the locking plate 5 matches the shape of the annular groove, allowing the locking plate 5 to be tightly fitted into the groove 3. As a preferred embodiment, the inner ring of the locking plate 5 can be designed with a structure featuring protrusions or grooves to further enhance the fitting stability with the annular groove, while also achieving circumferential limitation. By designing the locking plate 5 as two or more pieces and forming a ring structure, the inner ring of the locking plate 5 can be fitted into the annular groove of the rotating shaft body 1. This design enhances the installation stability of the locking plate 5, and the combination of multiple locking plates 5 improves the compatibility between the locking plate 5 and the rotating shaft body 1, solving the problem of traditional locking plate installation relying on the gantry assembly structure. Compared with the prior art, the technical solution of this application not only simplifies the installation process but also significantly improves the system's maintenance convenience and adaptability, possessing high practical value.

[0030] In a specific implementation, the washer 4 has a threaded hole 6, and the locking plate 5 has a through hole 7. The fastening component 8 passes through the through hole 7 of the locking plate 5 and is fixedly connected to the threaded hole 6 of the washer 4. The size and position of the threaded hole 6 and the through hole 7 must be precisely matched to ensure that the fastening component 8 can pass smoothly and achieve a secure connection. The fastening component 8 can be a bolt, screw, or other fastener with a threaded structure. As a preferred embodiment, the number of threaded holes 6 and through holes 7 can be multiple to further enhance the stability of the connection. Furthermore, the materials chosen for the washer 4 and the locking plate 5 should have sufficient strength and wear resistance to withstand vibration and load changes during long-term use. Specifically, the connection between the washer 4 and the locking plate 5 is achieved through the fastening component 8. This design avoids the loosening problems caused by vibration or load changes in traditional connection methods. Through the cooperation of the threaded hole 6 and the through hole 7, the fastening component 8 can tightly fix the washer 4 and the locking plate 5, thereby improving the overall stability and reliability of the rotating shaft tooling. Compared with existing technologies, this technical solution simplifies the installation process, reduces the operational complexity during disassembly and assembly, and significantly improves the system's maintenance convenience and adaptability. As a result, the connection between washer 4 and locking plate 5 is more secure, effectively solving the loosening problem caused by vibration or load changes, and ensuring the stability and reliability of the rotating shaft fixture during long-term use.

[0031] like Figure 2As shown, the shaft body 1 has an internal oil passage 9. The inlet 10 of the oil passage 9 is located on the end face of the first end of the shaft body 1, and the outlet 11 of the oil passage 9 is located on the side of the shaft body 1 between the washer 4 and the retaining ring 2. Specifically, the inlet 10 of the oil passage 9 is located on the end face of the first end of the shaft body 1 to facilitate the injection of lubricating oil; the outlet 11 of the oil passage 9 is located on the side of the shaft body 1 between the washer 4 and the retaining ring 2 to ensure that the lubricating oil can directly act on the parts that need lubrication. As a preferred embodiment, the oil passage 9 can be designed as a straight line, a spiral, or a branch to adapt to different lubrication requirements. In addition, the diameter and length of the oil passage 9 can be optimized according to the working conditions of the shaft and the viscosity of the lubricating oil to ensure smooth flow and effective lubrication of the lubricating oil.

[0032] To address this issue, the technical solution utilizes an oil passage 9 constructed within the shaft body 1 to ensure smooth flow of lubricating oil, thereby resolving the problem of insufficient lubrication within the shaft. The well-designed inlet 10 and outlet 11 of the oil passage 9 not only facilitate lubricating oil injection but also ensure that the lubricating oil directly reaches the parts requiring lubrication, improving lubrication effectiveness and extending the shaft's service life. Compared to existing technologies, this solution eliminates the need for additional lubrication devices or complex maintenance operations, simplifying the lubrication process, reducing maintenance costs, and simultaneously enhancing the shaft's operational stability and reliability.

[0033] Example 2:

[0034] like Figure 3 As shown, this embodiment relates to a gantry rotation system, including a fixed gantry 12 and a rotating gantry 13. The rotating gantry 13 is mounted on the fixed gantry 12 via a rotating shaft fixture. The rotating shaft body 1 passes through the shaft holes of the fixed gantry 12 and the rotating gantry 13, and the washer 4 and the retaining ring 2 are respectively pressed against both sides of the shaft holes of the fixed gantry 12 and the rotating gantry 13. The rotating shaft fixture is the same as that described in Embodiment 1. This gantry rotation system mounts the rotating gantry 13 onto the fixed gantry 12 via the rotating shaft fixture, with the rotating shaft body 1 passing through the shaft holes of the fixed gantry 12 and the rotating gantry 13, and the washer 4 and the retaining ring 2 respectively pressing against both sides of the shaft holes of the fixed gantry 12 and the rotating gantry 13. This design, through the combined pressing of the retaining ring 2 and the washer 4 in the rotating shaft fixture, and the fixed connection between the locking plate 5 and the washer 4, achieves quick assembly and disassembly with high stability, while significantly improving the system's maintenance convenience and adaptability. Compared with existing technologies, this technical solution simplifies the installation process, reliably limits axial displacement, and reduces dependence on the gantry assembly structure, thereby improving the reliability and maintenance efficiency of the equipment.
