Description

Technical Field

[0001] The utility model relates to the technical field of fluid loading and unloading arms, in particular to an outrigger structure of a fluid loading and unloading arm. Background Art

[0002] The outrigger structure of the fluid loading and unloading arm is an important component of the loading and unloading arm system. It is responsible for directly connecting with the loading and unloading ports of transport containers such as tank trucks or tank ships to realize the loading and unloading operations of liquid or gaseous media. The outrigger arm can be extended and rotated within a certain range to adapt to the loading and unloading needs of different positions and angles. At present, the outrigger arm joints are fixed by flanges, but the flanges are only fixed to each other by screws and lack effective clamping. Therefore, when affected by external vibrations, the tightness of the fit between the flanges is difficult to ensure, and the sealing performance cannot be effectively ensured, which makes it easy for the medium to leak. In addition, when the outrigger arm needs to be disassembled, the screws need to be repeatedly loosened, which is time-consuming and labor-intensive and cannot meet the needs of quick disassembly. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an outrigger structure for a fluid loading and unloading arm, which solves the problem that when the outrigger arm needs to be disassembled, the screws need to be repeatedly loosened, which is time-consuming and labor-intensive and cannot meet the need for quick disassembly.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an outrigger structure of a fluid loading and unloading arm, comprising a column, a support block fixedly connected to the annular side surface of the column, an inner arm provided on the upper surface of the support block, a telescopic cylinder provided on the upper surface of the inner arm, an outer arm provided on the left side of the inner arm, a joint provided between the inner arm and the outer arm, flange 1 fixedly connected to the opposing surfaces of the outer arm and the inner arm, a protective ring fixedly connected to the left surface of the joint, a connecting pipe movably sleeved in the protective ring, flange 2 fixedly connected to the opposing back surfaces of the joint and the connecting pipe, and the two flanges 2 are respectively fixed to the two flanges 1 by screws.

[0007] As a preferred technical solution of the present invention, the inner wall of the protective ring is provided with two slots, and the inner walls of the two slots are fixedly connected with blocking blocks.

[0011] (3) Beneficial effects

[0012] 1. When the connecting pipe moves to the right, it pushes the two arc blocks to move together, compressing the two springs. At this time, when the outer arm is pushed to the top and rotates, the connecting pipe also rotates. At this time, the two connecting blocks fixed on the connecting pipe rotate in the slot, opening the limit, and the outer arm can be disassembled.

[0020] The embodiment of the present application provides an outrigger arm structure for a fluid loading and unloading arm, which effectively solves the problem that the outrigger arm joint is fixed by a flange. However, the flanges are only fixed to each other by screws and lack effective clamping. Therefore, when affected by external vibrations, the tightness of the fit between the flanges is difficult to ensure, and the sealing performance cannot be effectively ensured, which makes it easy for medium leakage to occur. In addition, when the outrigger arm needs to be disassembled, the screws need to be repeatedly loosened, which is time-consuming and labor-intensive and cannot meet the need for quick disassembly. Example

[0021] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the overall idea of ​​the embodiment of this application is as follows:

[0022] In view of the problems existing in the prior art, the utility model provides an outrigger structure of a fluid loading and unloading arm, comprising a column 1, a support block 2 fixedly connected to the annular side of the column 1, an inner arm 3 provided on the upper surface of the support block 2, a telescopic cylinder 5 provided on the upper surface of the inner arm 3, an outer arm 4 provided on the left side of the inner arm 3, a joint 6 provided between the inner arm 3 and the outer arm 4, a flange 7 fixedly connected to the opposite surfaces of the outer arm 4 and the inner arm 3, a protective ring 11 fixedly connected to the left surface of the joint 6, a connecting pipe 10 movably sleeved in the protective ring 11, and the joint 6 and the connecting pipe 10 are connected. The back sides of the tubes 10 are fixedly connected with flanges 2 8, and the two flanges 2 8 are respectively fixed to the two flanges 1 7 by screws. When the outer arm 4 needs to be disassembled, the outer arm 4 is pressed to the right to drive the flanges 2 8 fixed thereto to move together. The flanges 2 8 will drive the connecting tube 10 fixed thereto to move during the force process. The connecting tube 10 will push the two arc blocks 16 to move together during the movement to the right, compressing the two springs 14. At this time, when the outer arm 4 is pushed to the top and rotated, the connecting tube 10 also rotates accordingly.

[0023] Two slots 12 are provided on the inner wall of the protective ring 11, and blocking blocks 15 are fixedly connected to the inner walls of the two slots 12. Two connecting blocks 9 are fixedly connected to the annular side surface of the connecting pipe 10, and the two connecting blocks 9 are movably engaged with the two slots 12 respectively. The two connecting blocks 9 fixed on the connecting pipe 10 rotate in the slots 12, and the limit is opened, so that the outer arm 4 can be disassembled. The easy-to-disassemble design of the outer arm 4 allows for quick maintenance and repair work without disassembling the entire loading and unloading arm, thereby reducing maintenance time and cost.

[0024] The inner walls of the two card slots 12 are provided with limiting grooves 13, and arc blocks 16 are movably connected in the two limiting grooves 13. The surfaces of the two arc blocks 16 are fixedly connected with springs 14, and the two springs 14 are fixedly connected to the two limiting grooves 13 respectively. During the connection and installation process of the outer arm 4, the elastic force of the two springs 14 pushes the two arc blocks 16 to the left. This thrust can ensure the fixation of the position of the connecting pipe 10, so that the connecting pipe 10 and the protective ring 11 are tightly fitted and ensure a sealed connection. In this way, even if they are subjected to external collisions and impacts, pressure can be continuously applied to ensure stability, thereby effectively avoiding loosening and leakage at the joint 6.

[0025] Working principle:

[0026] When the outer arm 4 needs to be disassembled, the outer arm 4 is pressed to the right to move the flange 2 8 fixed thereto. The flange 2 8 will drive the connecting pipe 10 fixed thereto to move during the force process. The connecting pipe 10 will push the two arc blocks 16 to move together during the movement to the right, compressing the two springs 14. At this time, when the outer arm 4 is pushed to the top and rotated, the connecting pipe 10 also rotates accordingly. At this time, the two connecting blocks 9 fixed on the connecting pipe 10 rotate in the slot 12, opening the limit, and the outer arm 4 can be disassembled. The easy-to-disassemble design of the outer arm 4 allows for quick maintenance and repair work without disassembling the entire loading and unloading arm, thereby reducing maintenance time and cost. During the connection and installation process of the outer arm 4, the elastic force of the two springs 14 pushes the two arc blocks 16 to the left. This thrust can ensure that the position of the connecting pipe 10 is fixed, so that the connecting pipe 10 and the protective ring 11 are tightly fitted and ensure a sealed connection. In this way, even if they are subjected to external collisions and impacts, pressure can be continuously applied to ensure stability, thereby effectively preventing loosening and leakage at the joint 6.
