Therefore, the production of marine pipeline is very important, as a process of shipbuilding, it is necessary to achieve "opening red" with quality and quantity.

[0003] The pipeline of different systems is complex on the ship, and multiple bend angles of spatial three-dimensional bent pipe may appear. The current pipe bending machine can only bend one bend angle at a time, and after bending one bend angle, the clamp needs to be loosened, and then the size and angle of the second bend angle are determined according to the drawing calculation arc length. If the two bends are 0 degrees, i.e. plane bending, only a level ruler is needed to measure the angle. If it is a spatial three-dimensional bend, the second bend has a corner relative to the first bend, and the corresponding arc length needs to be calculated according to the pipe diameter and corner angle, which is time-consuming and laborious, and requires high skill level of construction personnel. If the pipe is long, a little error in the corner will cause a large size error of the whole pipe, affecting the installation on the ship.

[0053] In this embodiment, a specific embodiment of a spatial three-dimensional pipe bending measuring device is provided. The magnet 1 is used to fix the spatial three-dimensional pipe bending measuring device on the pipe, because the state of the angle is not a rotation in a plane, but can be any azimuth position in space, so the device should be directly installed on the pipe, the goniometer 3 is used to measure the exact angle of rotation, and the base 4 is used to connect to the pipe, because the diameters of the pipes are different, the opening of the first V-shaped groove 41 can adapt to various pipe diameters, which helps to solve the technical problem that there is no way to manufacture a pipe with high-precision angle under a spatial angle in the prior art.

[0054] In an embodiment, the base 4 is a cuboid structure, and the first V-shaped groove 41 penetrates along the length direction of one side of the base 4.

[0055] In the embodiment, the specific structure of the base 4 and the specific implementation of the first V-shaped groove 41 are provided. The base 4 adopts a relatively regular structure, which facilitates the goniometer 3 to find the reference position. When the pipeline is in a horizontal state initially, the reference position is relatively easy to obtain when the base 4 has a regular structure.

[0056] In an embodiment, the goniometer mounting seat 2 is arranged at one end of the magnet 1.

[0057] In the embodiment, the goniometer mounting seat 2 is arranged on the magnet 1, and the goniometer 3 is arranged thereon.

In an embodiment, the present application further provides a pipe bending device, which comprises a driven wheel disc 5 and a driving clamp mold 6, a fixing device 7 and a spatial three-dimensional pipe bending measurement device.

[0061] The driven wheel disc 5 rotates along the central axis, and the recess 51 with an arc-shaped cross section is arranged along the edge of the driven wheel disc 5.

In an embodiment, the fixing device 7 comprises a first clamp plate 71 and a second clamp plate 72.

[0067] The second clamping plate 72 is arranged in the same direction as the first clamping plate 71, and one end of the first clamping plate 71 and the second clamping plate 72 is close to the passive wheel disc 5.

[0068] In the embodiment, a specific structure of the first clamping plate 71 and the second clamping plate 72 is provided. The close to the passive wheel disc 5 is to make the part with the maximum stress deformation when the pipe is bent to be in the holding state of the clamping device, so that the bending deformation of the pipe is minimized. As shown in the figure, Figure 6 When the first part is bent, the space three-dimensional pipe measuring device can be changed to the current position, and the above bending process is repeated again.

[0069] In an embodiment, the pipe bending device further comprises a pipe bending machine body 8 capable of moving the pipe in the length direction.

[0070] In the embodiment, a specific implementation of the pipe bending machine body 8 is provided, which can continuously send out the straight pipe to the position of the passive wheel disc 5 and the active clamping die 6 for bending to form the pipe.

[0071] In an embodiment, the active clamping die 6 has a second V-shaped groove 61 or a semicircular arc groove matching the diameter of the pipe in the length direction of the pipe.

[0072] In the embodiment, a second V-shaped groove 61 is provided in the active clamping die 6 to fix the straight pipe. The semicircular arc groove can prevent damage to the straight pipe during bending to some extent, so that the pipe is deformed.

[0073] Figure 7 The figure shows the flowchart of a pipe bending method in another embodiment of the present application. As shown in the figure, Figure 7 In an embodiment, the present application further provides a pipe bending method based on the pipe bending device as described, which comprises:

[0074] S101, clamping the pipe along the first V-shaped groove 41 of the base 4.

[0075] In this step, a specific step of clamping the pipe along the first V-shaped groove 41 of the base 4 is provided. The goniometer 3 is in a vertical state with the front facing the end of the straight pipe, which is convenient for reading.

[0076] S102, the magnet 1 is attached to the pipe near the base 4 and clamps the base 4.

[0077] In this step, a specific step of attaching the magnet 1 to the pipe near the base 4 and clamping the base 4 is provided.

[0078] S103, the active clamping die 6 is rotated to bend the pipe by the driving device.

[0080] S104, reading the reading of the goniometer 3 as a measurement result.

[0081] In this step, a specific step of reading the reading of the goniometer 3 as a measurement result is provided.

[0082] In this embodiment, based on the above process, the process of bending the straight pipe for the first time can be read data.

[0083] In an embodiment, based on the pipe bending device, after the step of reading the reading of the goniometer 3 as a measurement result, the method further comprises:

[0084] Loosen the active clamp 6, move the pipe along the length direction by a predetermined size through the pipe bending machine body 8, and proceed to the next bending.

[0085] In this embodiment, a specific embodiment of loosening the active clamp 6, moving the pipe along the length direction by a predetermined size through the pipe bending machine body 8, and proceeding to the next bending is provided. After the first bending is completed, the pipe bending machine body 8 will extend the straight pipe forward by a predetermined size, and finally repeat the above steps to complete the second bending process. In this way, multiple bending angles can be formed, and this way can construct multiple bending angles in space.

[0086] Figure 8 The structure diagram of the spatial three-dimensional pipe measuring device provided on the pipe in another embodiment of the application is shown in FIG. Figure 8 As shown in the drawing, the pipe in the drawing is the result of multiple angle bending. After the first bending, the subsequent bending angles are no longer regular directions, but spatial directions. The prior art cannot accurately position them. For example, the angle between section A and section B in Figure 8 can only be measured by a protractor, and the measurement of the protractor in the irregular direction of space is very inaccurate, and its reference surface is also very difficult to determine and align. However, the spatial three-dimensional pipe measuring device in the application adopts a spatial reference method. The goniometer 3 can measure the angle itself. The goniometer 3 reference is positioned on the bent pipe. Therefore, no matter how complex the pipe is, accurate measurement can be performed. As long as one section is placed on the reference table, the relative angle of the other end can be measured. For example, section A is placed horizontally, and the first adjacent bend is also placed horizontally. Then, the relative angle of section B can be measured.

[0087] It should be noted that the straight pipe, the elbow pipe, and the goniometer mounting seat 2 can be attracted by the magnet 1.

Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and the modification or equivalent replacement is also regarded as falling within the protection scope of the present application.
