Description

Technical Field

[0001] The present application relates to the technical field of fixtures, and particularly to a multi-purpose track fixture. Background Art

[0002] As an important protective structure for the inner wall of a ship, the marine thin-film enclosing system is crucial for ensuring the heat insulation effect and compressive capacity of storage tanks, which are usually used to transport key substances such as liquefied natural gas. Therefore, its sealing performance and connection performance must meet extremely high standards.

[0003] During the construction process of the marine thin-film system, the construction and welding of the shielding layer are particularly crucial. However, traditional welding methods mainly rely on manual operation, which undoubtedly increases the complexity of operation and the risk of errors when facing large storage tanks and numerous welding positions. Due to the large number and wide distribution of welding positions, manual welding is prone to problems such as poor sealing performance and unstable connection, thus affecting the safety and reliability of the entire system.

[0004] To solve this problem, people have begun to use fixtures to assist in the welding process of the shielding layer. The fixtures are installed at the grommet positions of the shielding layer. By connecting the fixtures of two adjacent shielding layers, the welding stability can be significantly increased. However, there are still some deficiencies in the existing fixture designs. As Figure 1 shown, the grommet positions of the shielding layer 6 have grooves 61 on both sides. The clamping plates of the fixture usually clamp on the side of the grommet position of the shielding layer 6 with the groove 61. However, the fitting effect between the clamping plate and the groove 61 at the grommet position directly affects the stability of the fixture installed on the shielding layer 6. If the fitting effect is poor, it may cause the fixture to loosen or fall off, thereby affecting the welding quality of the shielding layer and the stability of the overall structure. Therefore, a fixture that increases the stability of clamping on the shielding layer is needed. Summary of the Invention

[0005] In order to increase the stability of the fixture installed at the grommet position of the shielding layer, the present application provides a multi-purpose track fixture.

[0006] The multi-purpose track fixture provided by the present application adopts the following technical solutions:

[0007] A multi-purpose track fixture includes a connecting portion, a fixing portion, a movable portion, a fixing component, and an inflation component installed on the connecting portion. The fixing portion and the movable portion clamp on both sides of the shielding layer with grooves. The fixing component is used to fix the movable portion to the connecting portion. The inflation component includes a sliding plate, two groups of first air bags, and two groups of second air bags. The two groups of first air bags are respectively installed on the sides of the fixing portion and the movable portion close to each other. The two groups of second air bags are both installed on the connecting portion. The two groups of first air bags are respectively communicated with the two groups of second air bags. The sliding plate is used to squeeze the second air bags.

[0008] By adopting the above technical solution, the fixing part and the movable part respectively clamp the position of the shielding layer with the groove from both sides, and the fixing component is used to stably fix the movable part and the connecting part. When the sliding plate in the inflation component squeezes the second airbag, the gas flows into the first airbag to make it expand, so that the first airbag closely fits the inner wall of the groove of the shielding layer.

[0009] Continuing to inflate makes the first airbag expand further, which can better fit the irregular surface in the groove, eliminate the tiny gaps, and increase the contact area and clamping accuracy. This design not only enhances the stability between the fixture and the shielding layer, but also effectively avoids the problems of loosening or falling off caused by insufficient clamping, thus improving the quality of the shielding layer welding and the stability of the overall structure.

[0010] Optionally, the fixing component includes a sliding rod, a fixing rod, a positioning semi-ring and a torsion spring. The fixing rod is installed on the connecting part, and the sliding rod is installed on the movable part; the positioning semi-ring is hinged to the sliding rod and is used to sleeved on the outer wall of the fixing rod. The positioning semi-ring is provided with a positioning block, and a plurality of positioning grooves for the positioning block to be inserted are opened on the outer wall of the fixing rod; the torsion spring is installed between the positioning semi-ring and the sliding rod, and the elastic force of the torsion spring is used to drive the positioning block to be inserted into the positioning groove under normal state.

[0011] By adopting the above technical solution, the positioning block can be selectively inserted into different positioning grooves according to needs, so as to realize the precise adjustment of the relative position between the movable part and the connecting part. This flexible position adjustment function makes the fixture more convenient and reliable when adapting to shielding layer grooves of different sizes or shapes, effectively improving the applicable range and installation accuracy of the fixture. At the same time, under the action of the elastic force of the torsion spring, the positioning block is firmly inserted into the selected positioning groove under normal state, ensuring the stable connection between the movable part and the connecting part, and further enhancing the working reliability of the whole fixture.

[0012] Optionally, the fixing component further includes a positioning part and a disassembly part. One end of the sliding rod is fixed to the sliding plate; the sliding rod is detachably connected to the movable part through the disassembly part, and the positioning part is used to fix the movable part and the connecting part.

[0013] By adopting the above technical solution, the detachable connection between the sliding rod and the movable part through the disassembly part realizes the flexible control of the airbag inflation process. Specifically, in the initial stage, when the sliding rod is connected to the movable part, pushing the sliding rod can synchronously drive the movable part and the sliding plate to move, so as to effectively squeeze the second airbag to complete the initial inflation.

[0014] After the fixed part and the movable part successfully clamp both sides of the shield layer flower knot position, the connection between the sliding rod and the movable part is released, and the movable part is firmly fixed on the connecting part by using the positioning part. At this time, further sliding the sliding rod will not only not affect the position stability of the movable part, but also act on the sliding plate alone to continuously compress the second airbag, and then provide more gas to the first airbag, ensuring that the airbag fully expands and fits tightly with the shield layer, greatly improving the stability and reliability of the fixture fixation.

[0015] Optionally, the disassembly part includes a fixed block, a first spring and an unlocking part. The movable part is provided with a movable groove, the fixed block is movably installed in the movable groove, and the sliding rod is provided with a fixing groove for the fixed block to be inserted; both ends of the first spring are respectively connected with the fixed block and the movable groove, and the elastic force of the first spring is used to drive the fixed block to be inserted into the fixing groove under normal conditions, and the unlocking part is used to push the fixed block back into the movable groove.

[0016] By adopting the above technical solution, the plug-in fit between the fixed block and the fixing groove realizes the effective fixation of the sliding rod and the movable part, ensures the stable connection between the two in the working state, and can clamp the flower knot positions of different sizes of the shield layer; and when it is necessary to cancel the fixation between the sliding rod and the movable part, the fixed block can be pushed back into the movable groove by using the unlocking part.

[0017] When it is necessary to cancel the clamping of the flower knot position of the shield layer by the fixed part and the movable part, move the sliding rod towards the side away from the fixed part. When the fixing groove is exactly opposite to the movable groove, at this time, the fixed block will quickly reset into the fixing groove under the action of the first spring, completing a new round of fixing action, and at the same time facilitating the synchronous control of the moving positions of the movable part and the sliding plate.

[0018] Optionally, the positioning part includes a plug-in block and a guiding surface. The side wall of the movable part is provided with a first plug-in groove communicated with the movable groove, the plug-in block is slidably installed in the first plug-in groove, and the connecting part is provided with a plurality of second plug-in grooves; the guiding surface is arranged on the plug-in block. When the fixed block is pushed back into the movable groove, the fixed block abuts against the guiding surface, and the guiding surface is used to guide the plug-in block to be inserted into the second plug-in groove.

[0019] By adopting the above technical solution, when it is necessary to release the fixation between the sliding rod and the movable part, the unlocking part can be used to withdraw the fixing block from the fixing groove. During this process, the fixing block can also skillfully guide the insertion block to insert into the second insertion groove on the connecting part, so as to realize the instant fixation between the movable part and the connecting part. Further, when the fixing block retracts into the movable groove, with the elastic force provided by the first spring, the fixing block always keeps in close contact with the outer wall of the sliding rod. In this way, even in this case, the insertion block can still be firmly located in the second insertion groove, avoiding the free sliding of the movable part and increasing the stability of the two sides clamped at the bowknot position.

[0020] Optionally, one end of the insertion block close to the second insertion groove is inclined upward, and smooth layers are provided on both the insertion block and the inner wall of the first insertion groove.

[0021] By adopting the above technical solution, setting one end of the insertion block to be inclined upward can effectively release the abutting relationship between the fixing block and the insertion block when the fixing block is reinserted into the fixing groove under the action of the spring. At the same time, due to the smooth layers provided on the insertion block and the inner wall of the first insertion groove, the frictional resistance is reduced, enabling the insertion block to slide smoothly under its own gravity, thus disengaging from the connection state with the second insertion groove and realizing the convenient unlocking function.

[0022] Optionally, the unlocking part includes a push rod, a pull rod and a connecting column. The sliding rod is provided with a pulling groove and a connecting groove. The two ends of the connecting groove are respectively communicated with the fixing groove and the pulling groove; the pull rod is slidably installed in the pulling groove, the push rod is slidably installed in the fixing groove and is used to abut against the fixing block, and the two ends of the connecting column are respectively connected with the push rod and the pull rod.

[0023] By adopting the above technical solution, the design of the unlocking part can realize the quick unlocking operation of the fixing block. Specifically, when pulling the pull rod, the connecting column drives the push rod to move, and the push rod pushes the fixing block out of the fixing groove, so that the sliding rod is disengaged from the movable part, facilitating the adjustment of the position of the movable part. This structure improves the operation convenience of the fixture, reduces the assembly time, and at the same time ensures the flexibility and stability of the fixture during use.

[0024] Optionally, a rubber layer is provided on the inner wall of the positioning semi-ring.

[0025] By adopting the above technical solution, providing a rubber layer on the inner wall of the positioning semi-ring can enhance the friction between the positioning semi-ring and the fixing rod, improve the tightness of their connection, prevent the positioning semi-ring from loosening due to vibration or external force, and thus enhance the overall stability of the fixture. This solution further ensures the reliability and safety of the fixture during use.

[0026] Optionally, a second spring is disposed inside the second airbag, and the elastic force of the second spring is used to drive the second airbag to maintain an inflated state.

[0027] By adopting the above technical solution, the second spring can effectively ensure that the second airbag quickly returns to the inflated state when not externally squeezed. When the sliding plate no longer applies pressure to the second airbag, relying on the elastic force of the second spring, the second airbag can automatically return to its initial inflated form, thereby ensuring that the fixture can always maintain good fitting performance and stability during multiple uses. At the same time, it is convenient for the user to quickly adjust and reuse the fixture, improving work efficiency.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By providing an inflation assembly, when the sliding plate squeezes the second airbag, gas flows into the first airbag to make it expand, so that the first airbag closely adheres to the inner wall of the shielding layer groove; continuous inflation makes the first airbag further expand, which can better adhere to the irregular surface in the groove, eliminate tiny gaps, and increase the contact area and clamping accuracy; it enhances the stability between the fixture and the shielding layer, and effectively avoids the loosening or falling off problems caused by insufficient clamping, thereby improving the quality of shielding layer welding and the stability of the overall structure;

[0030] 2. By providing a disassembling member and a positioning member, after the fixing part and the movable part successfully clamp both sides of the shielding layer knot position, the connection between the sliding rod and the movable part is released by using the disassembling member, and the movable part is firmly fixed on the connecting part by using the positioning member; at this time, further sliding the sliding rod will not only not affect the position stability of the movable part, but also can act on the sliding plate alone to continuously compress the second airbag, and then supply more gas to the first airbag.

[0041] The inflation assembly 4 includes a sliding plate 41, two groups of first airbags 42 and two groups of second airbags 43. The two groups of first airbags 42 are respectively adhered to the side of the fixed part 2 and the movable part 3 that are close to each other; the two groups of second airbags 43 are both arranged in the movable chamber 13, and the two groups of second airbags 43 are respectively connected with the two groups of first airbags 42 through elastic tubes; the sliding plate 41 is slidably installed in the movable chamber 13 to abut against the two second airbags 43 so as to fill the gas in the second airbags 43 into the first airbags 42.

[0042] A second spring 44 is provided in the second airbag 43 , and the elastic force of the second spring 44 is used to drive the second airbag 43 to return to the expanded state; that is, when the sliding plate 41 is no longer in contact with the second airbag 43 , the second airbag 43 returns to its original state under the elastic force of the second spring 44 .

[0043] Referring to Figure 3 and Figure 4 In this embodiment, the fixing component 5 includes a sliding rod 51, a fixing rod 52, a positioning semi-ring 53, a positioning member 54 and a disassembling member 55. The fixing rod 52 is fixed to the mounting housing 12, and the extending direction of the fixing rod 52 is the same as the sliding direction of the movable plate. A plurality of positioning grooves 521 are formed in the outer wall of the fixing rod 52, and all the positioning grooves 521 are arranged at intervals along the extending direction of the fixing rod 52.

[0044] Referring to Figure 4 , one end of the sliding rod 51 is fixed to the sliding plate 41. A through hole 31 is formed in the movable part 3, and the sliding rod 51 passes through the through hole 31 and is exposed to the outside. The disassembling member 55 is used to fix the sliding rod 51 to the inner wall of the through hole 31. When the disassembling member 55 cancels the fixation between the sliding rod 51 and the movable part 3, the positioning member 54 is used to fix the movable part 3 to the inner wall of the sliding groove 14.

[0045] Referring to Figure 3 , the positioning semi-ring 53 is rotatably mounted at one end of the sliding rod 51 away from the sliding plate 41. A positioning block 531 is arranged on the inner wall of the positioning semi-ring 53, and the outer diameter of the positioning block 531 is adapted to the inner diameter of the positioning groove 521. When it is necessary to fix the sliding rod 51 to the connecting part 1, by rotating the positioning semi-ring 53, the positioning semi-ring 53 is sleeved on the outer wall of the fixing rod 52, and the positioning block 531 is inserted into the positioning groove 521.

[0046] A torsion spring is installed between the positioning semi-ring 53 and the sliding rod 51. The elastic force of the torsion spring is used to drive the positioning block 531 to be inserted into the selected positioning groove 521 under normal conditions, further increasing the connection stability between the sliding rod 51 and the mounting housing 12. And in this embodiment, a rubber layer is provided in the positioning semi-ring 53, and the rubber layer is provided to facilitate sleeving the positioning semi-ring 53 on the outer wall of the fixing rod 52.

[0047] Referring to Figure 4 , the disassembling member 55 includes a fixing block 551, a first spring 552 and an unlocking part 554. An activity groove 32 is formed in the inner wall of the through hole 31. The fixing block 551 is movably installed in the activity groove 32. A fixing groove 511 for inserting the fixing block 551 is formed in the bottom wall of the sliding rod 51. Two ends of the first spring 552 are respectively fixed to the fixing block 551 and the inner wall of the activity groove 32, and the elastic force of the first spring 552 forces the fixing block 551 to move towards the side away from the activity groove 32.

[0048] Referring to Figure 5, the unlocking part 554 includes a push rod 555, a pull rod 556 and a connecting column 557. The push rod 555 is slidably installed in the fixing groove 511, and when the fixing block 551 is inserted into the fixing groove 511, the push rod 555 abuts against the fixing block 551 and moves towards one side of the fixing groove 511; the sliding rod 51 is provided with a pulling groove 512 and a connecting groove 513. The pulling groove 512 is arranged at the bottom of the sliding rod 51, and the pull rod 556 is slidably installed in the pulling groove 512. In this embodiment, a pull ring 558 is arranged at one end of the pull rod 556 away from the pulling groove 512; the connecting column 557 is slidably installed in the connecting groove 513, and both ends of the connecting column 557 are connected to the pull rod 556 and the push rod 555 respectively.

[0049] When the pull rod 556 is pulled, the connecting column 557 drives the push rod 555 to move, and the push rod 555 pushes the fixing block 551 out of the fixing groove 511, so that the sliding rod 51 is disconnected from the movable part 3, facilitating the adjustment of the position of the movable part 3. This structure improves the operation convenience of the fixture, reduces the assembly time, and at the same time ensures the flexibility and stability of the fixture during use.

[0050] Refer to Figure 6 , in this embodiment, the positioning part 54 includes a plug-in block 541 and a guiding surface 542. A first plug-in groove 33 communicating with the movable groove 32 is formed in the side wall of the movable part 3, and one end of the first plug-in groove 33 away from the movable groove 32 is inclined upward; the plug-in block 541 is slidably installed in the first plug-in groove 33, and a plurality of second plug-in grooves 15 for the plug-in block 541 to be inserted are formed in the inner wall of the sliding groove 14; in this embodiment, smooth layers are provided on both the plug-in block 541 and the inner wall of the first plug-in groove 33; the provision of the smooth layer can reduce the friction between the plug-in block 541 and the first plug-in groove 33, so that the plug-in block 541 slides towards one side of the movable groove 32 under the action of its own gravity.

[0051] The guiding surface 542 is arranged on one side of the plug-in block 541 close to the movable groove 32. The side of the plug-in block 541 away from the movable groove 32 is defined as a reference surface, and the distance between the guiding surface 542 and the reference surface gradually increases from the side away from the movable groove 32 to the side close to the movable groove 32; the guiding surface 542 is used to guide the movement of the plug-in block 541 inserted on the side away from the movable groove 32.

[0052] In this embodiment, an extension groove 34 communicating with the first plug-in groove 33 is formed in the inner wall of the movable groove 32, and an extension part 559 is integrally formed on the outer wall of the fixing block 551. The extension part 559 is located in the extension groove 34 and is used to abut against the guiding surface 542 of the plug-in block 541.

[0053] When it is necessary to release the fixation between the sliding rod 51 and the movable part 3, the unlocking part 554 can be used to withdraw the fixing block 551 from the fixing groove 511. During this process, the extending part 559 abuts against the guiding surface 542, so that the plugging block 541 is plugged into the second plugging groove 15 under the guidance of the guiding surface 542, thereby realizing the fixation of the movable part 3 and the connecting part 1. After the fixing block 551 retracts into the movable groove 32, with the elastic force provided by the first spring 552, the fixing block 551 always keeps in close contact with the outer wall of the sliding rod 51. In this way, even in this case, the plugging block 541 can still be firmly located in the second plugging groove 15, avoiding the situation where the movable part 3 slips freely, and increasing the stability of clamping on the opposite sides of the bowknot position.

[0054] The implementation principle of a multi-purpose track clamp according to an embodiment of the present application is as follows:

[0055] The fixing part 2 and the movable part 3 respectively clamp the position of the shielding layer 6 with the groove 61 from both sides. By using the plugging cooperation between the fixing block 551 and different fixing grooves 511, the fixation of the movable part 3 and the connecting part 1 is realized; at this time, further sliding the sliding rod 51 will not only not affect the position stability of the movable part 3, but also act on the sliding plate 41 alone to continuously compress the second airbag 43, and then supply more gas to the first airbag 42; so that the first airbag 42 better fits the irregular surface in the groove 61, eliminates the tiny gap, and improves the contact area and clamping accuracy.

[0056] This design not only enhances the stability between the clamp and the shielding layer 6, but also effectively avoids the problems of loosening or falling off caused by insufficient clamping, thereby improving the welding quality of the shielding layer 6 and the stability of the overall structure.

[0057] In addition, the connection of two adjacent clamps can not only increase the stability during the welding process of two adjacent shielding layers 6; and tracks can be provided between two adjacent clamps to be able to set up a robotic arm for welding work; after welding is completed, the clamp can be connected to an external hoisting device to facilitate subsequent work such as packing and placing the shielding layer 6, so that the clamp has multiple uses and improves the practicability of the clamp.

[0058] The above is the preferred embodiment of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
