Description

Technical Field

[0001] The utility model relates to the technical field of pipeline leakage monitoring, and particularly relates to an installation structure for a leakage monitoring terminal. Background Art

[0002] During pipeline welding, usually two pipelines are spliced together and then welded at the joint on the outer wall of the pipeline. For the welding of large pipelines, due to the long weld seam distance and the limited length of the welding wire, the welding process is usually discontinuous. However, the discontinuous welding process is likely to cause defects at the joint of the weld seams corresponding to adjacent two weldings, and in severe cases, the welded pipeline will leak. In addition to welding, other factors such as rubbing during pipeline transportation can also cause pipeline leakage. During pipeline production, processing, and transportation, it is very necessary to perform flaw detection on the pipeline, because this can prevent difficult-to-remedy leakage when the pipeline is officially put into use.

[0003] As a leakage monitoring terminal for pipelines, a flaw detector can detect the leakage location of the pipeline. However, for large pipelines, the method of manually holding the flaw detector for monitoring has low efficiency on the one hand and is difficult to comprehensively inspect the pipeline on the other hand.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

A support plate is fixedly installed at the upper end of the base, and a pressing plate is detachably connected to the upper end of the support plate by bolts. An electric slide rail is fixedly installed at the upper end of the pressing plate, a slider is slidably installed on the electric slide rail, a rotating support is fixedly installed at the upper end of the slider, a micro motor is fixedly installed on the rotating support, a flaw detector body is rotatably installed on the rotating support, and the output end of the micro motor is in transmission connection with the flaw detector body.

[0007] As a further technical solution, two positioning wheels are installed at the upper end of the support plate. The two positioning wheels are respectively located on both sides of the electric slide rail, and the distances from the two positioning wheels to the electric slide rail are the same.

[0008] As a further technical solution, auxiliary rollers are installed at the lower end of the pressing plate, and the axes of the two positioning wheels are symmetrical about the vertical plane where the axis of the auxiliary roller is located.

[0009] As a further technical solution, the axes of the positioning wheels and the axes of the auxiliary rollers are both parallel to the guiding direction of the electric slide rail.

[0010] As a further technical solution, inclined platforms are fixedly installed on both sides of the base, and the inclined platforms are used to provide auxiliary support for the pipeline to be tested to roll onto the support plate.

[0011] As a further technical solution, a bracket is provided at the side end of the base. A servo motor is fixedly installed at the upper end of the bracket.

Detailed implementation manners

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-3 shown, a leakage monitoring terminal installation structure includes a base 1, and the upper end surface of the base 1 is horizontal. A support plate 2 is fixedly installed on the upper end of the base 1, and a pressure plate 3 is detachably connected to the upper end of the support plate 2 by bolts. An electric slide rail 4 is fixedly installed on the upper end of the pressure plate 3, a slider 5 is slidably installed on the electric slide rail 4, a rotating support 6 is fixedly installed on the upper end of the slider 5, a micro motor 7 is fixedly installed on the rotating support 6, a flaw detector body 8 is rotatably installed on the rotating support 6, and the output end of the micro motor 7 is in transmission connection with the flaw detector body 8.

[0024] Through the above technical solutions, the main structural content of the leakage monitoring terminal installation structure is provided in this embodiment. During specific work, first place the pipeline to be tested on the upper end of the support plate 2, and then insert the pressure plate 3 into the pipeline to be tested, and fix the part of the pressure plate 3 extending out of the pipeline to be tested to the support plate 2 by bolts, forming a state where the support plate 2 and the pressure plate 3 jointly clamp the pipe wall of the pipeline to be tested. Through the setting of the slider 5 and the electric slide rail 4, the position of the flaw detector body 8 in the pipeline can be axially adjusted, and through the setting of the rotating support 6, the flaw detector body 8 can be radially adjusted to the specific flaw detection position under the drive of the micro motor 7. To sum up, the technical solution provided in this embodiment can replace the method of manually holding a flaw detector for pipeline leakage monitoring, improve the monitoring efficiency, and can perform a more comprehensive flaw detection inspection on large pipelines through multi-directional adjustment.

[0025] As Figure 2 、 5 shown, two positioning wheels 9 are installed on the upper end of the support plate 2. The two positioning wheels 9 are respectively located on both sides of the electric slide rail 4, and the distances from the two positioning wheels 9 to the electric slide rail 4 are the same. An auxiliary roller 10 is installed at the lower end of the pressure plate 3. The axes of the two positioning wheels 9 are symmetric about the vertical plane where the axis of the auxiliary roller 10 is located. The axes of the positioning wheels 9 and the axis of the auxiliary roller 10 are both parallel to the guide of the electric slide rail 4.

[0026] Through the above technical solution, this embodiment provides the structures of the positioning wheel 9 and the auxiliary roller 10. Among them, the positioning wheel 9 can perform preliminary positioning and continuous support on the pipeline to be measured. When the pressing plate 3 and the support plate 2 clamp the pipe wall of the pipeline to be measured, the positioning wheel 9 fits against the outer wall of the pipeline to be measured, while the auxiliary roller 10 fits against the inner wall of the pipeline. Therefore, while the pipeline to be measured is clamped and positioned, it can also rotate around its own axis. By controlling the rotation of the pipeline to be measured around its own axis, the flaw detector body 8 can perform more uniform flaw detection monitoring on the pipeline to be measured from multiple angles.

[0027] As Figures 1-3 shown, inclined platforms 11 are fixedly installed on both sides of the base 1, and the inclined platforms 11 are used to provide auxiliary support for the pipeline to be measured to roll onto the support plate 2.

[0028] Through the above technical solution, in this embodiment, through the setting of the inclined platforms 11, it is convenient to push the relatively heavy pipeline to the upper end of the support plate 2, that is, it is convenient for loading and unloading during the monitoring process.

[0029] As Figures 3-4 shown, a bracket 12 is provided at the side end of the base 1. A servo motor 13 is fixedly installed at the upper end of the bracket 12. The output end of the servo motor 13 is drivingly connected to a swing arm 14. A clamping assembly for clamping the pipe wall of the pipeline to be measured is installed at the end of the swing arm 14 away from the servo motor 13.

[0030] A chute 15 is formed on the swing arm 14. The clamping assembly includes a movable clamping plate 16 that is interactively connected to the chute 15. One end of the chute 15 is fixedly connected to a fixed clamping plate 17. A threaded hole is formed in the side wall at the other end of the chute 15, and a screw 18 is threadedly connected to the threaded hole. One end of the screw 18 is rotatably connected to the end face of the movable clamping plate 16.

[0031] Through the above technical solution, in this embodiment, through the coordinated movement setting of the servo motor 13, the swing arm 14, and the clamping assembly, after the movable clamping plate 16 and the fixed clamping plate 17 clamp the inner wall of the pipeline to be measured, the screw 18 is tightened, and then the swing arm 14 rotates around the output shaft under the drive of the servo motor 13, which can drive the pipeline to be measured to rotate around its own axis. It should be noted that the axis of the output shaft of the servo motor 13 must coincide with the axis of the pipeline to be measured.

[0032] The above has described a detailed description of an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
