Description

Technical Field

[0001] The utility model relates to the technical field of submarine pipeline maintenance, in particular to a multi-freedom submarine pipeline clamp. Background Art

[0002] Submarine pipeline clamps are used to clamp the suspended section of the pipeline, reduce fatigue damage to the pipeline caused by external factors such as ocean currents and waves, and improve the service life and safety of the pipeline;

[0003] The existing application number is CN202111476749.X, which is a maintenance support clamp for a suspended section of a submarine pipeline. The patent document discloses a locking mechanism with adjustable length on the opposite side to quickly adjust the height of the clamping mechanism to adapt to submarine pipelines with different suspended heights. Specifically, the clamp includes a clamping mechanism, a jacking mechanism and a locking mechanism. The locking mechanism includes a support column, a sleeve sleeved outside the support column and a latch. The support column is fixedly mounted on a base, the top of the sleeve is fixed on a lower support portion, and the bottom is sleeved outside the support column. The support column is provided with a plurality of first sockets spaced apart along the height direction, and a second socket aligned with one of the first sockets is provided on the sleeve. The latch is inserted into the aligned first and second sockets to position the relative positions of the sleeve and the support column and adjust the length of the locking mechanism. However, the jacking mechanism and the locking mechanism used in the patent document both have installation space requirements and cannot be arranged under a submarine pipeline with a suspended height that is too low, which has limitations. Therefore, the present application provides a multi-degree-of-freedom submarine pipeline clamp. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a multi-degree-of-freedom submarine pipeline clamp, which, on the basis of ensuring the support and clamping of submarine pipelines with different suspended heights, can also be arranged under submarine pipelines with too low suspended heights, thereby reducing the demand for installation space at the bottom of the submarine pipeline and adapting to different installation environments.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A multi-degree-of-freedom submarine pipeline clamp is provided, comprising a supporting base, a hinged plate and an L-shaped insert; the supporting base is installed on the seabed, the supporting base is connected to the L-shaped insert through two hinged plates of equal length, the two ends of the hinged plate are rotatably connected to the supporting base and the L-shaped insert respectively, a side limiter is detachably fixedly installed on the L-shaped insert, the L-shaped insert and the side limiter act together on both sides of the pipeline to clamp the pipeline.

[0007] Furthermore, the hinge plate and the support base are locked in position by fasteners.

[0008] Furthermore, a shaft rod is slidably installed between the two hinged plates, and the shaft rod is fixedly installed on an adjustment base on the seabed.

[0009] Furthermore, the outer side surface of the shaft rod abuts against the inner side surfaces of the two hinge plates at the same time.

[0010] Furthermore, the side limiter is connected to the L-shaped insert through a plurality of bolt and nut sets.

[0011] Furthermore, the L-shaped insert is provided with a sliding groove for the bolt to slide.

[0012] Furthermore, the L-shaped insert and the side limiter are respectively provided with arc surfaces matching the outer side surface of the pipeline.

[0013] Furthermore, the supporting base and the adjusting base are respectively fixedly installed on the seabed by a plurality of positioning nails.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the multi-degree-of-freedom submarine pipeline clamp of the utility model example, the hinged plate can rotate freely on the support base, so that the vertical distance between the L-shaped insert and the support base has a large adjustment range, and pipelines with different suspended heights can be supported and clamped.

[0016] 2. In the multi-degree-of-freedom submarine pipeline clamp of the utility model example, the hinged plate extends upwardly toward the side of the support base, thereby reducing the space requirement for the bottom of the pipeline, so that it can be arranged under a pipeline with a too low suspension height, reducing the requirement for installation space at the bottom of the submarine pipeline and adapting to different installation environments.

[0017] 3. In the multi-degree-of-freedom submarine pipeline clamp of the utility model example, the L-shaped insert is in an L-shaped structure, and the side limiter is installed on the horizontal part of the side of the L-shaped insert. Compared with the pipe clamp in the prior art, the installation position of the fastener is at a certain distance from the pipeline, and the installation position of the fastener is at the side of the pipeline rather than the bottom, so the demand for the installation space of the fastener is reduced and the operation is more convenient.

[0029] Embodiment 1:

[0030] like Figure 1-3 As shown, this embodiment provides a multi-degree-of-freedom submarine pipeline clamp, including a support base 11, a hinged plate 12 and an L-shaped insert 13; the support base 11 is fixedly installed on the seabed through a plurality of positioning pins Ⅰ, and the support base 11 is connected to the L-shaped insert 13 through two hinged plates 12 of equal length; the hinged plate 12 extends upwardly from the side of the support base 11, reducing the space requirement for the bottom of the pipeline 1, so that it can be arranged under the pipeline 1 with a too low suspension height, reducing the requirement for the installation space at the bottom of the submarine pipeline, and adapting to different installation environments.

[0031] like Figure 1 As shown, the two ends of the hinged plate 12 are rotatably connected to the support base 11 and the L-shaped insert 13 respectively, and the side limiter 15 is detachably fixedly installed on the L-shaped insert 13. The L-shaped insert 13 and the side limiter 15 are respectively provided with arc surfaces matching the outer side surface of the pipe 1. The L-shaped insert 13 and the side limiter 15 act together on both sides of the pipe 1 to clamp the pipe 1.

[0032] The side stopper 15 is connected to the L-shaped insert 13 via a plurality of bolt and nut sets.

[0033] When the multi-degree-of-freedom submarine pipeline clamp of the present application is used to support and clamp the pipeline 1:

[0034] First, insert the L-shaped insert 13 to the lower side of the pipe 1, adjust the angle of the L-shaped insert 13, and install the side stopper 15 on the L-shaped insert 13 to clamp the pipe 1;

[0035] Then, the hinge plate 12 is manually rotated, and the support base 11 is fixed to the seabed using a plurality of positioning pins I, and then the relative angle between the hinge plate 12 and the support base 11 is locked to stably support the L-shaped insert 13 and the pipeline 1 together.

[0036] Since the support base 11, the two hinged plates 12 and the L-shaped insert 13 form a parallelogram mechanism, the two hinged plates 12 can rotate synchronously on the support base 11, so that the vertical distance between the L-shaped insert 13 and the support base 11 has a large adjustment range, and the pipes 1 with different suspended heights can be supported and clamped.

[0037] In order to increase the adjustable performance of the side stopper 15 on the L-shaped insert 13, as shown in FIG. Figure 3 As shown, a slide groove 14 for the bolt to slide is provided on the L-shaped insert 13 , so that the side limiter 15 can be quickly assembled and disassembled on the L-shaped insert 13 .

[0038] In this embodiment, the hinge plate 12 and the support base 11 are locked in position by fasteners.

[0039] Embodiment 2:

[0040] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 2 As shown, in this embodiment, a shaft rod 22 is slidably installed between the hinged plates 12, and the shaft rod 22 is fixedly installed on an adjustment base 21 on the seabed. The outer side surface of the shaft rod 22 is simultaneously in contact with the inner side surfaces of the two hinged plates 12, and the adjustment base 21 is fixedly installed on the seabed by a plurality of positioning pins II.

[0041] By changing the distance between the adjustment base 21 and the support base 11, adjusting the rotation angle of the hinge plate 12 on the support base 11, and then fixing the adjustment base 21 on the seabed, the relative angle between the hinge plate 12 and the support base 11 can be stably maintained.

[0042] In the present application, the L-shaped insert 13 is an L-shaped structure, and the side limiter 15 is installed on the horizontal part of the side of the L-shaped insert 13. Compared with the pipe clamp in the prior art, the installation position of the fastener is at a certain distance from the pipe 1, and the installation position of the fastener is on the side of the pipe 1 rather than the bottom, which reduces the demand for installation space of the fastener and makes operation more convenient.

[0043] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other.

[0044] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present utility model, the other technical features will not be described in detail here.
