[0027] refer to Figure 1 to Figure 5 The embodiment of the present application provides a quick-connect pipe docking device, which may include a base 1, a fixed plate 2, a movable plate 3, two groups of fixed components and two pipes 5. The base 1 has a first seat surface and a second seat surface arranged opposite to each other in a first direction, and the first direction is the same as the thickness direction of the base 1; the fixed plate 2 is fixed to the side of the first seat surface away from the second seat surface; the movable plate 3 is arranged on the side of the first seat surface away from the second seat surface and has the freedom to move along the second direction, the fixed plate 2 is located on the moving path of the movable plate 3, and the second direction is perpendicular to the first direction; the two groups of fixed components are arranged opposite to each other on the side of the fixed plate 2 and the movable plate 3 away from the base 1 in the second direction; the two pipes 5 are connected to the two groups of fixed components in a one-to-one correspondence and the axial directions are the same as the second direction.

[0028] A quick pipe docking device proposed in an embodiment of the present application connects two pipes 5 to two sets of fixed components respectively. The two pipes 5 are coaxially arranged at this time and the axial direction is the same as the second direction. At this time, the movable plate 3 is pushed to move along the second direction so that the movable plate 3 is close to the fixed plate 2. The movable plate 3 drives the corresponding pipe 5 to be close to the corresponding pipe 5 of the fixed plate 2, and finally the ends of the two pipes 5 that are close to each other are made to collide with each other or be separated by a predetermined distance. In this way, the pipes 5 can be docked with each other with high stability to ensure the subsequent welding quality, wherein the predetermined distance can be selected according to actual welding needs.

[0029] Specifically, Figure 1 As shown, the first direction is the X direction, which is also the thickness direction of the base 1 , the second direction is the Y direction, the base 1 can be rectangular, then the second direction Y can be the length direction of the base 1 , and the subsequent third direction is the Z direction, which is the width direction of the base 1 .

[0030] It should be understood that the pipe quick docking device can be placed on the ground when in use, in which case the first direction X is the same as the direction of gravity, and the first seat surface is located above the second seat surface.

[0031] refer to Figure 1 In an exemplary embodiment, the pipe quick docking device may also include a first slide rail 61, a limiting portion 62 and a telescopic member 63, the first slide rail 61 is fixed to the side of the first seat surface away from the second seat surface and extends along the second direction Y, the movable plate 3 is slidably matched with the first slide rail 61; the limiting portion 62 is fixed to the side of the movable plate 3 away from the fixed plate 2; the telescopic member 63 is connected between the movable plate 3 and the limiting portion 62 and has the freedom to telescope along the second direction Y.

[0032] Specifically, the telescopic member 63 can be a hydraulic cylinder, which has a cylinder body and a piston rod, wherein the cylinder body is connected to the limiting portion 62, and the piston rod is connected to the movable plate 3. When the hydraulic cylinder is working, the piston rod is extended and retracted along the second direction Y, thereby pushing or pulling the movable plate 3 along the second direction Y to approach or move away from the fixed plate 2. During the process, the movable plate 3 slides on the first slide rail 61, so that the two pipes 5 can be connected or separated by controlling the extension and retraction of the hydraulic cylinder.

[0033] Further, such as Figure 1 As shown, there are two first slide rails 61, and the two first slide rails 61 are spaced apart in the third direction Z. The hydraulic cylinder is located between the two first slide rails 61, and the movable plate 3 slides with the two first slide rails 61 at the same time, so that when the hydraulic cylinder pushes or pulls the movable plate 3, the sliding of the movable plate 3 is more stable.

[0034] refer to Figure 1 to Figure 3In an exemplary embodiment, the fixing assembly arranged on the fixing plate 2 may include two supporting parts 41, a mounting seat 42, a motor 43, a pulley 44 and a belt 46. The two supporting parts 41 are arranged on the fixing plate 2 at intervals in the second direction Y, and the pipeline 5 is arranged on the side of the two supporting parts 41 away from the fixing plate 2; the mounting seat 42 is arranged on the fixing plate 2; the motor 43 is fixed to the side of the mounting seat 42 away from the fixing plate 2 and the axial direction of the output shaft is the same as the second direction Y; the pulley 44 is sleeved on the outer periphery of the output shaft of the motor 43; one end of the belt 46 is connected to the pulley 44, and the other end is connected to the fixing plate 2 through a force measuring assembly. The belt 46 bypasses the pipeline 5 and provides a force for the pipeline 5 to fit the two supporting parts 41; the belt 46 is located between the two supporting parts 41.

[0035] Specifically, when connecting the pipe 5, the pipe 5 is placed on the two support parts 41. At this time, the axial direction of the pipe 5 is the same as the second direction Y, and the belt 46 passes around the top of the pipe 5. The motor 43 is controlled to rotate forward, and the motor 43 drives the pulley 44 to rotate synchronously. When the pulley 44 rotates, the belt 46 is wrapped around the pulley 44. At this time, the belt 46 is tightened. The tightened belt 46 applies a force to the pipe 5 to fit the support part 41, so that the pipe 5 can be connected to the corresponding fixed component.

[0036] It should be understood that when the pipeline 5 needs to be disassembled or after welding is completed, the motor 43 is controlled to reverse, and the motor 43 drives the pulley 44 to rotate synchronously. When the pulley 44 rotates, the belt 46 wrapped around the pulley 44 is gradually released. At this time, the belt 46 is loose, and the pipeline 5 can be pulled out.

[0037] It should be noted that the belt 46 is located between the two support parts 41 , so that the force on the pipeline 5 is more balanced, which facilitates the connection of the pipeline 5 .

[0038] refer to Figure 2 In an exemplary embodiment, the force measuring assembly may include a positioning block 451 and a dynamometer 452, wherein the positioning block 451 is disposed on a side of the fixing plate 2 facing away from the base 1; the dynamometer 452 is connected to a side of the positioning block 451 facing away from the fixing plate 2, and an end of the belt 46 away from the pulley 44 is connected to the dynamometer 452.

[0039] Specifically, the pipe quick docking device of the present application can not only dock metal pipes for welding, but also dock plastic pipes for subsequent hot-melt connection.

[0040] It should be understood that when connecting the plastic pipe, after the belt 46 is tightened, the tension gauge 452 will have the tension on the corresponding end of the belt 46, so as to calculate the pressure on the plastic pipe, prevent the plastic pipe from being deformed due to excessive pressure, and ensure that the subsequent plastic pipe can be used normally.

[0041] In an exemplary embodiment, the tension meter 452 has a hook, and the tension meter 452 is configured to display a corresponding tension value in response to the tension applied to the hook; a connecting ring is provided at one end of the belt 46 away from the pulley 44, and the connecting ring is detachably connected to the hook.

[0042] Specifically, when connecting the pipe 5, the staff can hold the connecting ring and pull the belt 46 to make the belt 46 pass over the top of the pipe 5, and then hang the connecting ring on the hook of the tension gauge 452. In this way, when the pipe 5 is long, the pipe 5 can be directly placed on the corresponding support part 41, and then the belt 46 can be operated, without inserting the pipe 5 between the belt 46 and the support part 41.

[0043] It should be understood that after welding is completed, the belt 46 is first loosened, and then the connecting ring is removed from the hook, and the welded pipe can be removed without pulling the pipe out from between the belt 46 and the support part 41, which is more convenient and quick to use.

[0044] refer to Figure 3 to Figure 5 In an exemplary embodiment, the fixing assembly arranged on the fixing plate 2 may also include a second slide rail 47 and a third slide rail 48, the second slide rail 47 is fixed on the fixing plate 2 and extends along the third direction Z, the mounting seat 42 is slidably engaged with the second slide rail 47, and the third direction Z is respectively perpendicular to the first direction X and the second direction Y; the third slide rail 48 is fixed on the fixing plate 2 and extends along the third direction Z, and the positioning block 451 is slidably engaged with the third slide rail 48.

[0045] Specifically, the second slide rail 47 extends along the third direction Z, and the mounting seat 42 slidably cooperates with the second slide rail 47, so that the mounting seat 42 can slide along the third direction Z; similarly, the third slide rail 48 extends along the third direction Z, and the positioning block 451 slidably cooperates with the third slide rail 48, so that the positioning block 451 can slide along the third direction Z.

[0046] Wherein, if the belt 46 is in the following state before being tensioned: Figure 3 In the state shown, when the motor 43 works to drive the belt 46 to be tightened, since both the mounting seat 42 and the positioning block 451 can slide along the third direction Z, the belt 46 will be tightened to drive the mounting seat 42 and the positioning block 451 to approach each other in the third direction Z until the portion of the belt 46 close to the mounting seat 42 and the positioning block 451 extends along the first direction X. Figure 5 As shown, the belt 46 is tensioned at this time, and the force exerted by the belt 46 on the pipe 5 toward the base 1 is twice the value measured by the dynamometer 452. This makes it easy to calculate the force exerted on the pipe 5 and to control when to stop the motor 43 to complete the connection of the pipe 5.

[0047] refer to Figure 1 to Figure 3In an exemplary embodiment, the support portion 41 may include a support column 411 and a cushion block 412, the support column 411 is fixed to a side of the fixing plate 2 away from the base 1 and extends along the first direction X; the cushion block 412 is fixed to an end of the support column 411 away from the fixing plate 2; a side of the cushion block 412 away from the support column 411 is provided with an arc-surface recessed structure having a depth direction the same as the first direction X; the pipe 5 and the arc-surface recessed structure have two contact areas opposite to each other in the third direction Z.

[0048] Specifically, the pipe 5 is arranged on two corresponding pads 412. When the pad 412 is provided with an arc-surface concave structure with a depth direction the same as the first direction X on one side of the support column 411, the pipe 5 conflicts with the arc-surface concave structure, so that the connection of the pipe 5 is more stable.

[0049] Further, such as Figure 3 As shown, the pipe 5 and the arc-surface recessed structure have two relative contact areas in the third direction Z, so when the pipe 5 is connected to the pad 412, it is difficult for the pipe 5 to roll along the periphery, that is, it is difficult for the pipe 5 to rotate. In this way, the connection of the pipe 5 is more stable, which effectively improves the quality of subsequent metal pipe welding or plastic pipe hot-melt connection.

[0050] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
