Description

Technical Field

[0001] The utility model relates to the field of pipeline protection, in particular to a full-automatic pipeline anti-corrosion layer stripping experimental device. Background Art

[0002] Outdoor gas pipelines are susceptible to corrosion from groundwater, soil and atmospheric environment. Therefore, in order to protect the pipelines, the pipelines are generally covered with anti-corrosion layers. The peel strength test is a test to detect the adhesion between the anti-corrosion layer and the steel pipe. It is one of the indicators to check whether the anti-corrosion layer is qualified. The experimental process refers to SY / T4113 "Test Method for Performance of Pipeline Anti-corrosion Layer". For pipeline anti-corrosion layers with a pipe well less than 200mm, a ring specimen is used for peel strength test.

[0003] For example, the Chinese patent "A wave current strength test device for steel pipe anti-corrosion layer" with publication number CN201420792841 requires the operator to manually control the rotation of the winch, so as to cooperate with the lifting to drive the fixed clamp to peel off the anti-corrosion layer. First of all, the manual operation of the winch increases the labor burden of the staff, and the tension required for peeling can only be measured by the tensile gauge, and an accurate time-tension dynamic curve cannot be obtained. Moreover, the shape of the fixed clamp is not specified, and the figure only shows a hook-shaped structure, which makes it difficult to stably clamp the fixed anti-corrosion layer. It is easy to cause deviations in the measurement results. Utility Model Content

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0048] Please combine Figure 1 - Figure 3 The fully automatic pipeline anti-corrosion layer stripping experimental equipment of this embodiment includes the equipment that needs to be prepared before the experiment, that is, the pipeline with the anti-corrosion layer, the anti-corrosion layer is cut along the pipeline direction, and the sample strip of about 30cm is pulled out for easy clamping.

[0049] The specific experimental equipment includes an outer frame 1, and a pipeline support mechanism 2 for supporting the pipeline is arranged at the inner bottom of the outer frame 1. Specifically, the pipeline support mechanism 2 includes a support plate 21, an adjustment hole 22 is opened inside the support plate 21, an adjustment plate 23 is slidably installed in the adjustment hole 22, and one end of the adjustment plate 23 extends out of the support plate 21, and a support wheel 24 is rotatably installed at the end of the adjustment plate 23.

[0050] The supporting wheels 24 are used to contact the inner wall of the pipe. In the present embodiment, three supporting wheels 24 are provided, which can support the pipe from the inner wall of the pipe without affecting the rotation of the pipe.

[0051] In order to control the extension length of the adjustment plate 23, thereby adjusting the position of the support wheel 24, and conveniently support pipes of different sizes (inner diameters), an oblong through hole is also provided on one side of the support plate 21, and a control rod 25 is provided in the through hole. One end of the control rod 25 is fixedly connected to the adjustment plate 23, so the position of the adjustment plate 23 can be moved by the control rod 25. An external thread is provided on the control, and a fixing cap 26 is connected to the outside through a thread. When the fixing cap 26 is tightened, the fixing cap 26 and the outer wall of the support plate 21 are in contact and fit tightly, and the control rod 25 cannot drive the adjustment plate 23 to move, and the adjustment plate 23 is fixed.

[0052] The above-mentioned pipeline support mechanism 2 is provided with two groups, that is, the two groups of pipeline support mechanisms 2 jointly support the pipeline. One side of one group of pipeline support mechanisms 2 is fixedly connected with a fixed mounting plate 3, and the fixed mounting plate 3 is fixedly connected to the outer frame 1;

[0053] In order to facilitate the disassembly and assembly of the pipe belt, one side of the other set of pipe support mechanisms 2 is fixedly connected with a movable mounting plate 4, and one side of the movable mounting plate 4 is movably connected with an adjustable mounting seat 5. That is, the angles of the pipe support mechanism 2 and the movable mounting plate 4 can be adjusted, which is convenient for disassembly and assembly of the pipe.

[0054] Specifically, the adjustable mounting seat 5 includes a mounting seat plate 51 and a mounting shaft 52. The mounting seat plate 51 is fixedly connected to the outer frame 1. The mounting shaft 52 is fixedly connected inside the mounting seat plate 51, and the movable mounting plate 4 is movably sleeved on the outside of the mounting shaft 52, that is, the movable mounting plate 4 can rotate around the mounting shaft 52.

[0055] In order to prevent the movable mounting plate 4 from rotating, a fixed stopper 56 and a movable stopper 55 are provided on the mounting seat plate 51, and the fixed stopper 56 is fixedly connected to the mounting seat plate 51. In order to install the movable stopper 55, a mounting groove 54 is provided on the mounting seat plate 51, and a lower spring rod 53 is installed in the mounting groove 54, and the movable stopper 55 is sleeved on the lower spring rod 53.

[0056] The movable stopper 55 and the fixed stopper 56 are respectively located on both sides of the movable mounting plate 4, blocking the movable mounting plate 4 from both sides, so that the movable mounting plate 4 cannot rotate around the mounting axis 52. At this time, the angle direction of the movable mounting plate 4 is consistent with that of the fixed mounting plate 3; when the movable stopper 55 is manually controlled to move and the movable stopper 55 is away from the movable mounting plate 4 (the spring on the lower spring rod 53 is compressed), the movable mounting plate 4 can move around the mounting axis 52, which makes it convenient to disassemble and assemble the pipeline from one side of the movable mounting plate 4.

[0057] Please combine Figure 4 - Figure 6 In order to clamp and fix the pipeline anti-corrosion layer, a lifting movable frame 6 is movably connected inside the outer frame 1, and a fixing clamping mechanism 7 for clamping the anti-corrosion layer is arranged inside the lifting movable frame 6.

[0058] Specifically, the fixed clamping mechanism 7 includes a side slide block 71 and a lifting block 73. First, a fixing hole 61 is opened on the lifting movable frame 6, and the side slide block 71 is slidably installed in the fixing hole 61. One side of the side slide block 71 is set as an inclined surface, and a limiting groove 72 is opened on the inclined surface. Two side slide blocks 71 are provided.

[0059] Correspondingly, a lifting block 73 is arranged in the middle of the two side sliders 71, and both sides of the lifting block 73 are also arranged as inclined surfaces, and the inclined surfaces are fixedly connected with a limit bar 74. The limit bar 74 is slidably installed in the limit groove 72. In this embodiment, the limit groove 72 and the limit bar 74 can be arranged in a dovetail shape.

[0060] A clamping plate 75 is fixedly connected to the bottom of the side slider 71, that is, the side slider 71 passes through the fixing hole 61 on the lifting movable frame 6 and is fixedly connected to the clamping plate 75 below the lifting movable frame 6. Therefore, the side slider 71 cannot move up and down, and can only move along the fixing hole 61 direction.

[0061] When the lifting block 73 is controlled to move upward, the side sliders 71 on both sides will move closer to the middle with the cooperation of the limit groove 72 and the limit bar 74. The two clamping plates 75 are driven to move closer to the middle, and finally the anti-corrosion layer is clamped. In this embodiment, in order to prevent the anti-corrosion layer from sliding off, a conical structure can be laid on the inner side of the clamping plate 75. The conical structure is small in size and cannot pierce the anti-corrosion layer, so it is convenient to fix the anti-corrosion layer.

[0062] In order to control the movement of the lifting block 73, a connecting rod 76 is fixedly connected to the top of the lifting block 73, and the upper end of the connecting rod 76 passes through the lifting movable frame 6. In this embodiment, a limiting block 77 can also be fixedly connected to the connecting rod 76, and the limiting block 77 is fixedly connected to the connecting rod 76 to provide a limiting effect for the up and down movement of the connecting rod 76.

[0063] In summary, the lifting block 73 is driven to move upward by the connecting rod 76, and the side slider 71 can cooperate to drive the clamping plate 75 to move, so as to clamp the anti-corrosion layer. In addition, the peeling experiment also requires the anti-corrosion layer to be pulled apart. Therefore, a driving shaft 10 and a rotating drum 11 are also provided above the connecting rod 76. First, the rotating drum 11 is rotatably connected to the outer frame 1, and an internal thread is provided in the rotating drum 11. The driving shaft 10 is a threaded shaft, and the driving shaft 10 and the rotating drum 11 are threadedly connected.

[0064] In order to facilitate the detection of the time-tension dynamic curve during the anti-corrosion layer stripping process, a tensile gauge 13 is fixedly connected below the driving shaft 10, and the lower end of the tensile machine is fixedly connected to the connecting rod 76. The tensile gauge 13 can be connected to external equipment, such as a computer, so that the time-tension dynamic curve can be intuitively viewed.

[0065] In addition, a motor (not marked in the figure) is installed on the outside of the outer frame 1 by screws, and the output shaft of the motor is connected to the drum 11 by a belt 12. Because the driving shaft 10 and the dynamometer 13, and the dynamometer 13 and the connecting rod 76 are fixedly connected and cannot rotate, when the motor drives the drum 11 to rotate through the belt 12, the driving shaft 10 will be driven to move upward or downward.

[0066] In addition, a through hole is provided on the lifting movable frame 6, and a fixed shaft 8 is provided in the through hole, and the fixed shaft 8 is fixedly connected to the outer frame 1, and an auxiliary spring 9 is sleeved on the outer side of the fixed shaft 8 located at the upper part of the lifting movable frame 6. The fixed shaft 8 provides a limit and guide function for the up and down movement of the lifting movable frame 6.

[0067] In summary, when the driving shaft 10 moves upward, the connecting rod 76 is driven to move upward through the dynamometer 13, and the dynamometer 13 will display the vertical tension, which is displayed through a computer connected to the outside.

[0068] It should be noted that the above description has a limit block 77 on the connecting rod 76. Before the limit block 77 below contacts the lifting movable frame 6: when the connecting rod 76 moves upward, the side sliders 71 on both sides will move closer to the middle, driving the two clamping plates 75 to move closer to the middle, and finally clamping the anti-corrosion layer.

[0069] Then the lower limit block 77 contacts the lifting movable frame 6, and the connecting rod 76 continues to rise, which will drive the entire lifting movable frame 6 to move upward.

[0070] The implementation process and principle of a fully automatic pipeline anti-corrosion layer stripping test device in the embodiment of the present application are as follows:

[0071] (I): First, adjust the position of the support wheel 24 according to the inner diameter of the pipe, loosen the fixing cap 26, and move the position of the adjustment plate 23 through the control rod 25 to adjust the position of the support wheel 24 so that the three support wheels 24 on the support plate 21 can just fit on the inner wall of the pipe. Then tighten the fixing cap 26.

[0072] (ii): To install the pipeline, first manually control the movable stopper 55 to move so that the movable mounting plate 4 can rotate around the mounting axis 52. For example, after rotating ninety degrees, it is convenient to clamp the pipeline on the outside of the pipeline support mechanism 2 connected to the fixed mounting plate 3. After the pipeline reaches the predetermined position, the movable mounting plate 4 is reset and the movable stopper 55 is released. At this time, the movable mounting plate 4 and the fixed mounting plate 3 are in the same position and direction, and both sets of pipeline support mechanisms 2 can support the pipeline from the inside.

[0073] (III): Peel off a portion of the anti-corrosion layer according to the experimental standard. Then the motor and the belt 12 drive the drum 11 to rotate. When the drum 11 rotates, it drives the driving shaft 10 to move upward. The driving shaft 10 drives the lifting block 73 to move upward through the dynamometer 13 and the connecting rod 76;

[0074] When the lifting block 73 moves upward, first, when the limit block 77 does not contact the lifting movable frame 6, the lifting block 73 will drive the side sliding blocks 71 on both sides to move closer together through the cooperation of the limit groove 72 and the limit bar 74, thereby driving the two clamping plates 75 to move closer to the middle, and finally clamp the anti-corrosion layer.

[0075] When the limit block 77 below the connecting rod 76 contacts the lifting frame 6, the connecting rod 76 continues to rise, which will drive the entire lifting frame 6 to move upward. The fixed shaft 8 plays a guiding and limiting role. When the lifting frame 6 moves upward as a whole, it will drive the anti-corrosion layer upward. At this time, since the support wheel 24 in the pipeline support mechanism 2 supports the pipeline from the inside of the pipeline, the pipeline can rotate, but cannot move up and down, so the anti-corrosion layer can be peeled off. At the same time, since the pipeline can rotate (the support wheel 24 and the adjustment plate 23 are rotatably connected). That is, it peels and rotates at the same time. The direction of the tension on the anti-corrosion layer is always in a vertical state. During the peeling process of the anti-corrosion layer, the time-tension curve is measured by the tensile meter 13.

[0076] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
