Description

Technical Field

[0001] This utility model belongs to the field of maintenance equipment technology, and in particular relates to a maintenance fixture for a rotary joint of a loading and unloading arm. Background Technology

[0002] A loading boom is a specialized device for transferring fluid materials between tank trucks, tank ships, and pipelines. It not only efficiently and accurately completes loading and unloading tasks but also features excellent sealing performance and explosion-proof design, effectively preventing fluid material leakage and explosions during the process. Therefore, loading booms are widely used in the petrochemical industry, liquefied natural gas receiving terminals, and other fields. The various parts of the loading boom are mainly connected by rotary joints. These joints allow relative rotation between different parts of the boom and enable them to bear loads, serving as a crucial structural component for achieving omnidirectional spatial connections.

[0003] To ensure the long-term stable operation and extend the service life of the loading arm, regular maintenance of the rotary joint is crucial. During inspection, to facilitate more in-depth inspection and repair by maintenance personnel, the inner and outer rings of the rotary joint need to be separated. However, currently, maintenance personnel typically use pliers to clamp the rotary joint and forcibly separate it using tools such as pry bars. This operation not only poses certain safety hazards but also easily damages the rotary joint, affecting its subsequent use.

[0004] Therefore, there is an urgent need for a tooling for overhauling the rotary joint of the loading and unloading arm to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a maintenance fixture for the rotary joint of the loading and unloading arm, which improves the safety and efficiency of maintenance, and also makes the rotary joint and the rotary joint of the loading and unloading arm less susceptible to damage.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A maintenance fixture for a loading / unloading boom rotary joint is provided. The rotary joint includes an inner ring and an outer ring for sealing connection. The maintenance fixture for the loading / unloading boom rotary joint includes:

[0008] The bracket includes a first support plate and a second support plate spaced apart along the separation direction, and the outer ring can be detachably installed on the first support plate;

Therefore, they should not be construed as limitations on this utility model.

[0030] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a maintenance fixture for the rotary joint of the loading and unloading arm, which improves the safety and efficiency of maintenance and makes both the rotary joint 100 and the maintenance fixture for the rotary joint of the loading and unloading arm less susceptible to damage.

[0033] See Figure 1 and Figure 2 The rotary joint 100 includes a sealed inner ring 102 and an outer ring 101. The maintenance fixture for the rotary joint of the loading / unloading arm includes a bracket 1, a first connecting plate 2, and a drive rod 3. The bracket 1 includes components along the separation direction (…). Figure 1 The first support plate 11 and the second support plate 12 are spaced apart in the X direction. The outer ring 101 can be detachably installed on the first support plate 11. One end of the drive rod 3 passes through the second support plate 12 and is threadedly connected to the second support plate 12. The other end is detachably connected to the first connecting plate 2. The first connecting plate 2 can be detachably connected to the inner ring 102. The separation direction is the extension direction of the rotary joint 100.

[0034] This rotary joint maintenance fixture for the loading and unloading arm has a drive rod 3 threadedly connected to the second support plate 12. Therefore, when the drive rod 3 is turned, it rotates and moves along the separation direction, driving the inner ring 102 to move along the separation direction via the first connecting plate 2. The inner ring 102 gradually separates from the outer ring 101. The separation operation is convenient and quick, eliminating the need for forceful separation and ensuring that the components of the rotary joint 100 are not damaged, thus improving safety during maintenance. The first support plate 11 is connected to the outer ring 101, supporting it on the bracket 1 and preventing it from moving during separation. This prevents damage to the mating surfaces between the inner ring 102 and the outer ring 101, ensuring the subsequent transmission effect of the rotary joint 100. The drive rod 3 passes through the second support plate 12, which provides support for the drive rod 3 during movement, increasing the strength of the maintenance fixture and preventing the drive rod 3 from bending or deforming due to excessive force when turning it. This further ensures the safety of the loading and unloading arm rotary joint maintenance fixture during use. The first connecting plate 2 is detachably connected to the inner ring 102, and the drive rod 3 is detachably connected to the first connecting plate 2, which facilitates workers to quickly replace the rotary joint 100 to be maintained on the bracket 1, improving maintenance efficiency.

[0035] In an optional embodiment, see [link to relevant documentation] Figure 1 and Figure 2 The first connecting plate 2 is provided with a first threaded hole, the second support plate 12 is provided with a second threaded hole, and the drive rod 3 is provided with a screw part 31 that is threadedly engaged with both the first threaded hole and the second threaded hole. The screw part 31 passes through the first threaded hole and the second threaded hole, and the thread direction of the first threaded hole is opposite to that of the second threaded hole. When separating the inner ring 102 and the outer ring 101, the screw part 31 is screwed along the thread direction of the second threaded hole so that the screw part 31 can move away from the outer ring 101. Since the thread direction of the first threaded hole is opposite to that of the second threaded hole, there is no relative rotation between the screw part 31 and the first connecting plate 2, but the first connecting plate 2 has a tendency to rotate under the action of the screw part 31. When the rotational force of screwing the first screw part 31 is greater than the frictional force between the inner ring 102 and the outer ring 101, the first connecting plate 2 will rotate and, under the influence of the thread direction of the second threaded hole, will drive the inner ring 102 to move away from the outer ring 101, thereby completing the separation of the inner ring 102 and the outer ring 101. The drive rod 3 is threadedly connected to the first connecting plate 2 through the second threaded hole, so that the drive rod 3 can be connected or separated from the first connecting plate 2, realizing the detachable connection between the drive rod 3 and the first connecting plate 2.

[0036] Specifically, the first connecting plate 2 is provided with a connecting hole and a nut. The nut is fixed on the side of the first connecting plate 2 away from the first support plate 11. The first threaded hole is the nut hole. The first threaded hole is connected to the connecting hole. The screw part 31 passes through the connecting hole and the first threaded hole.

[0037] For example, the drive rod 3 is a screw, and the first connecting plate 2 is made of steel.

[0038] In another optional embodiment, the maintenance fixture for the rotary joint of the loading and unloading arm further includes several first fasteners, which pass through the first connecting plate 2 and are threadedly connected to the drive rod 3 to achieve a detachable connection between the drive rod 3 and the first connecting plate 2.

[0039] For example, the first fastener is a screw.

[0040] Optionally, see Figure 1 and Figure 2 The bracket 1 also includes several second connecting plates 13 extending along the separation direction. The two ends of each second connecting plate 13 are connected to a first support plate 11 and a second support plate 12, respectively. The first support plate 11, the second support plate 12, and the several second connecting plates 13 enclose a separation space 15, within which the rotary joint 100 is installed. The second connecting plates 13 connect the first support plate 11 and the second support plate 12 into a whole, improving the rigidity of the bracket 1 structure, ensuring the stability of the rotary joint 100 installed on the bracket 1, and guaranteeing the safety of the maintenance process.

[0041] For example, see Figure 1 and Figure 2 There are two second connecting plates 13, which are respectively located on both sides of the rotary joint 100. The two second connecting plates 13, the first support plate 11 and the second support plate 12 form a separation space 15 with a rectangular cross-sectional shape.

[0042] In this embodiment, the second connecting plate 13 can be disposed below the rotary joint 100, and the second connecting plate 13 is provided with a ball drop opening. A plurality of balls are disposed between the inner ring 102 and the outer ring 101. At the moment the inner ring 102 and the outer ring 101 separate, the balls will fall from between the inner ring 102 and the outer ring 101 and fall into the ball drop opening, so that the workers can quickly collect the balls and prevent the balls from rolling around.

[0043] Furthermore, the maintenance fixture for the rotary joint of the loading and unloading arm also includes a ball collection box, which is located at the ball drop outlet and is used to collect the balls of the rotary joint 100 to prevent the balls from rolling around.

[0044] Further, see Figure 1 and Figure 2The loading and unloading arm rotary joint maintenance fixture also includes a second fastener, and the bracket 1 also includes a third connecting plate 14. The third connecting plate 14 is connected to the first support plate 11 and is located outside the separation space 15. The second fastener passes through the third connecting plate 14 and can be connected to external equipment, so that the loading and unloading arm rotary joint maintenance fixture can be detachably installed on external equipment, and the reliability of the loading and unloading arm rotary joint maintenance fixture installed on external equipment is guaranteed.

[0045] For example, the external device is a fitter's platform, and the second fastener is a screw.

[0046] Optionally, see Figure 1 and Figure 2 An operating part 32 is provided at the end of the drive rod 3 away from the first connecting plate 2. The operating part 32 is configured to drive the drive rod 3 to rotate, so as to facilitate the operation of the staff.

[0047] In this embodiment, see Figure 1 and Figure 2 The drive rod 3 is made of bolt, and the operating part 32 is the head of the bolt. In other embodiments, the operating part 32 is a handle, which is held by the operator to drive the drive rod 3 to rotate.

[0048] Optionally, see Figure 1 and Figure 2 The maintenance fixture for the rotary joint of the loading and unloading arm also includes several third fasteners. The third fasteners pass through the first support plate 11 and can be fastened to the outer ring 101 to securely install the outer ring 101 to the first support plate 11.

[0049] Specifically, see Figure 1 and Figure 2 The first support plate 11 has a plurality of first through holes 111, and each of the first through holes 111 corresponds to a plurality of third fasteners. The third fasteners pass through the corresponding first through holes 111 and can be threadedly connected to the outer ring 101. The threaded connection not only ensures the firmness of the connection between the outer ring 101 and the first support plate 11, but also enables the detachable connection between the outer ring 101 and the first support plate 11.

[0050] In this embodiment, see Figure 1 and Figure 2 Multiple third fasteners are provided and spaced apart along the extension direction of the outer ring 101 to ensure the firmness of the outer ring 101 on the first support plate 11.

[0051] For example, the third fastener is a screw.

[0052] Optionally, see Figure 1 and Figure 2The maintenance fixture for the rotary joint of the loading and unloading arm also includes several fourth fasteners. The fourth fasteners pass through the first connecting plate 2 and can be fastened to the inner ring 102 to reliably connect the inner ring 102 to the first connecting plate 2.

[0053] Specifically, see Figure 1 and Figure 2 The first connecting plate 2 has several second through holes 21, each corresponding to a fourth fastener. The fourth fastener passes through the corresponding second through hole 21 and can be threadedly connected to the inner ring 102. The threaded connection not only ensures the firmness of the connection between the inner ring 102 and the first connecting plate 2, but also enables the detachable connection between the inner ring 102 and the first connecting plate 2.

[0054] In this embodiment, see Figure 1 and Figure 2 Figure 1 Figure 2 There are multiple fourth fasteners, which are symmetrically arranged about the drive rod 3 to ensure the reliability of the connection between the inner ring 102 and the first connecting plate 2.

[0055] For example, the fourth fastener is a screw.

[0056] The above are only specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model fall within the protection and disclosure scope of this utility model.
