Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and in particular to a pipeline pressure resistance testing device. Background Art

[0002] Pipelines are subject to tremendous pressure when in use. If there are points of uneven force or cracks on the pipeline, it may cause leakage of the transported materials and cause pollution at the least, or even cause serious hazards such as explosions. Therefore, after the pipeline is produced, it needs to be pressure tested. A special pressure test pump is used for the pipeline pressure test. The pressure test pump is connected to both ends of the pipeline to increase the pressure inside the pipeline and test whether there are any fault points on the pipeline.

[0003] In traditional pipeline pressure testing, the pipeline is usually placed on the ground, and the pressure test pump is connected to both ends of the pipeline for pressurization. During the actual test, a warning line is set around the pipeline to prevent damage to the surrounding area caused by pipeline failure and explosion. However, the pipeline cannot be fixed and supported, and it is difficult to protect the surrounding area when the pipeline explodes. This testing method has low safety and may be dangerous. Therefore, in order to improve the safety of pipeline testing, we propose a pipeline pressure test device. Summary of the invention

[0007] One end of the support plate is arranged in an inclined shape, the protection mechanism is rotatably arranged on the inclined end of the support plate, and the support mechanism is arranged on a side of the support plate away from the protection mechanism.

[0008] The support mechanism includes a stabilizing component, and there are multiple stabilizing components. The multiple stabilizing components are respectively arranged on the two support plates. The stabilizing component is rotatably connected to a support frame, and the multiple stabilizing components are staggered on both sides of the support frame. The stabilizing component is used to stably support the support frame, wherein a support plate is arranged on the support frame, and the support plate is arranged on the side of the protective mechanism away from the support plate.

[0009] The stabilization assembly includes a stabilization frame, a spring 1, a sliding rod and a support rod.

[0010] The protective mechanism includes a protective cover and an extrusion plate. The protective cover is arranged in a semicircular shape. The protective cover is rotatably arranged on the support plate. There are multiple extrusion plates, and multiple extrusion plates are arranged inside the protective cover. The extrusion plates are arranged in an arc shape. The two sides of the protective cover are respectively in contact with the two docking nozzles. The two protective covers are arranged opposite to each other. When the extrusion plates on the two protective covers are in contact with the pipeline, the tops of the two protective covers will not contact each other.

[0011] A plurality of pressing grooves are provided on one side of the protective cover close to the support plate, and the pressing grooves correspond to the support plates one by one, and the support plates are in contact with the pressing grooves on both protective covers.

[0012] The buffer mechanism includes a drive cylinder and an elastic component.

[0014] The working principle and beneficial effects of the present invention are:

[0015] 1. In the present invention, a support frame and a pressing groove are provided, and a plurality of support plates are provided on the support frame. The support plates are arranged in an arc shape. When the pipeline is tested, the pipeline is placed on the support plate for testing. When the pipeline is placed on the support plate, the support plate is pressed downward, and the support rod moves accordingly to squeeze the sliding rod, and the sliding rod slides into the stable frame, and the sliding rod squeezes the spring 1. Through the action of the spring 1, the downward movement of the support frame is supported and cushioned. When the pressure of the ruptured pipeline impacts the protective cover, the two protective covers rotate to both sides, and the two pressing grooves support the support plate as the pressing cover rotates, and the pressing cover lifts the support plate upward. Due to the weight of the pipeline, the pressing of the pipeline and the support plate on the pressing groove can also reduce the angle of the protective cover rotating to both sides due to the pressure impact, thereby strengthening the protection of the surroundings.

[0016] 2. In the present invention, by setting the protective covers, when the extrusion plates on the two protective covers contact the pipeline, the tops of the two protective covers will not contact each other. The two protective covers are set on both sides of the pipeline. The two protective covers are rotated to both sides of the pipeline through the support of the buffer mechanism, and the extrusion plates squeeze and fix the pipeline. The extrusion plates are arranged around the pipeline to squeeze and fix the pipeline in all directions to prevent the pipeline from rotating during the pressure test. When the pipeline fails and causes pressure relief, the released pressure will be released between the two protective covers through the top of the pipeline to prevent damage to surrounding equipment and workers.

[0017] 3. In the present invention, a driving cylinder is provided, and when the output end of the driving cylinder is extended, the protective cover can be pushed to surround the pipeline, and the extrusion plate on the protective cover surrounds and clamps the pipeline, and the elastic component can buffer the rotation of the protective cover when it is under pressure;

[0018] 4. In the present invention, by providing a sliding shaft and a second spring, when the pipeline releases pressure toward both sides, the pressure impacts the protective cover. At this time, since the output end length of the driving cylinder remains unchanged, the sliding shaft slides on the sliding groove, and the sliding rod 1 and the sliding rod 2 slide toward each other to squeeze the second spring, and at this time the protective cover rotates in a small range;

[0019] 5. In the present invention, the pipeline can be supported by setting a supporting mechanism, and the supporting plate can provide buffering when the pipeline is placed. The supporting plate can press the two protective covers, and the weight of the pipeline can also prevent the protective covers from being affected by pressure, and rotate at a larger angle. By setting a protective mechanism, the pipeline can be clamped and fixed while preventing the released pressure from impacting the surroundings and guiding the impact upward. By setting a buffering mechanism, the protective mechanism can be supported while preventing the protective cover from being damaged by a large impact to provide buffering.

DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 to Figure 6As shown, this embodiment proposes a pipeline pressure test device, including a support plate 1, a docking nozzle 2, a supporting mechanism, a protective mechanism and a buffer mechanism. Two support plates 1 are provided, and the two support plates 1 are arranged opposite to each other. Two docking nozzles 2 are provided, and the two docking nozzles 2 are respectively detachably arranged on both ends of the pipeline. The supporting mechanism is connected to the two support plates 1, and the supporting mechanism is arranged between the two support plates 1. The supporting mechanism is used to support the pipeline. There are two protective mechanisms, and the two protective mechanisms are respectively rotatably arranged on the two support plates 1. The protective mechanism is in contact with the docking nozzle 2. The protective mechanism is used to support and protect the pipeline. There are multiple buffer mechanisms, and the buffer mechanism is rotatably connected to the support plate 1. The buffer mechanism is used to buffer and support the protective mechanism. When testing the pipeline, the pipeline is placed on the supporting mechanism, and the buffer mechanism supports the protective mechanism. The protective mechanism clamps the pipeline on both sides of the pipeline and protects the surrounding of the pipeline. When a problem occurs in the pressure test of the pipeline, the pressure release in the pipeline causes an impact on the protective mechanism. The buffer mechanism supports the protective mechanism and buffers the rotation of the protective mechanism.

[0030] like Figure 1~Figure 2 As shown, one end of the support plate 1 is arranged to be inclined, the protective mechanism is rotatably arranged on the inclined end of the support plate 1, and the supporting mechanism is arranged on the side of the support plate 1 away from the protective mechanism. When the pipeline is not placed on the support plate 4, the output end of the driving cylinder 12 is shortened to drive the protective cover 9 to rotate to the side of the support plate 1.

[0031] like Figure 1~Figure 4As shown, the supporting mechanism includes a stabilizing component, and a plurality of stabilizing components are provided. The plurality of stabilizing components are respectively arranged on two supporting plates 1, and a supporting frame 3 is rotatably connected to the stabilizing component. The plurality of stabilizing components are staggeredly arranged on both sides of the supporting frame 3, and the stabilizing component is used to stably support the supporting frame 3, wherein a supporting plate 4 is provided on the supporting frame 3, and the supporting plate 4 is arranged on the side of the protective mechanism away from the supporting plate 1, and the stabilizing component includes a stabilizing frame 5, a spring 16, a sliding rod 7 and a strut 8, the stabilizing frame 5 is fixedly arranged at the bottom of the supporting plate 1, the spring 16 is arranged in the stabilizing frame 5, the sliding rod 7 is slidably arranged on the side of the stabilizing frame 5 close to the supporting frame 3, one end of the strut 8 is rotatably connected to one end of the sliding rod 7 extending out of the stabilizing frame 5, and the other end is rotatably connected to the supporting frame 3, and a plurality of supporting plates 4 are provided on the supporting frame 3 to support The plate 4 is set in an arc shape. When the pipeline is tested, it is placed on the support plate 4 for testing. When the pipeline is placed on the support plate 4, the support plate 4 is pressed downward, and the support rod 8 moves accordingly to squeeze the sliding rod 7. The sliding rod 7 slides into the stabilizing frame 5, and the sliding rod 7 squeezes the spring 6. Through the action of the spring 6, the downward movement of the support frame 3 is supported and cushioned. The support frame 3 supports the pipeline and supports the pipeline when the pipeline is placed on the support frame 3. This can avoid the pipeline from contacting the support plate 4 when placed and causing impact on the pipeline. The spring 6, sliding rod 7 and support rod 8 support and cushion the support frame 3. When the pipeline ruptures and causes impact on the protective cover 9, the gravity of the support plate 4 on the pressing groove 11 can also reduce the opening angle of the protective cover 9, thereby further strengthening the protective effect.

[0032] like Figure 1~Figure 4 As shown, the protective mechanism includes a protective cover 9 and an extrusion plate 10. The protective cover 9 is set in a semicircular shape, and the protective cover 9 is rotatably set on the support plate 1. There are multiple extrusion plates 10, and multiple extrusion plates 10 are set inside the protective cover 9. The extrusion plate 10 is set in an arc shape. The two sides of the protective cover 9 are respectively in contact with the two docking nozzles 2. The two protective covers 9 are set opposite to each other. When the extrusion plates 10 on the two protective covers 9 are in contact with the pipeline, the tops of the two protective covers 9 will not contact each other. The two protective covers 9 are set on both sides of the pipeline. The two protective covers 9 are supported by the buffer mechanism to rotate to the two sides of the pipeline. The extrusion plate 10 squeezes and fixes the pipeline. The extrusion plate 10 is set around and squeezes and fixes the pipeline in all directions to prevent the pipeline from rotating during the pressure resistance test. When the pipeline fails and causes pressure relief, the released pressure will impact the two protective covers 9. Since the two ends of the two protective covers 9 are in contact with the docking nozzle 2, the pressure can only be released through the upper part of the pipeline and the uncontacted gap between the two protective covers 9. The pressure is released upward into the air to prevent damage to surrounding equipment and personnel.

[0033] like Figure 1~Figure 2As shown, a plurality of pressing grooves 11 are provided on one side of the protective cover 9 close to the support plate 1, and the pressing grooves 11 correspond to the support plate 4 one by one, and the support plate 4 contacts the pressing grooves 11 on the two protective covers 9. When the support plate 4 moves downward under the weight of the pipeline, the support plate 4 gradually contacts the pressing grooves 11, and at the same time, the pressure of the support plate 4 on the pressing grooves 11 can make the two protective covers 9 surround the pipeline. When the pressure of the pipeline rupture impacts the protective cover 9, the two protective covers 9 rotate to both sides, and the two pressing grooves 11 support the support plate 4 as the pressing cover rotates, and the pressing cover lifts the support plate 4 upward. Due to the weight of the pipeline, the pressing of the pipeline and the support plate 4 on the pressing grooves 11 can also reduce the angle of the protective cover 9 rotating to both sides due to the pressure impact, thereby strengthening the protection of the surrounding area. When the support plate 4 supports the pipeline, the protective cover 9 rotates to squeeze and fix the pipeline through the multiple extrusion plates 10 arranged on the inner side.

[0034] like Figure 5~Figure 6 As shown, the buffer mechanism includes a drive cylinder 12 and an elastic component. The drive cylinder 12 is rotatably set on the support plate 1, and the elastic component is set on the side of the protective cover 9. The output end of the drive cylinder 12 is rotatably connected to the elastic component. The elastic component is used to buffer when the protective cover 9 rotates. When the output end of the drive cylinder 12 is shortened, the protective cover 9 rotates to the top of the support plate 1. When the output end of the drive cylinder 12 is extended, the protective cover 9 can be pushed to surround the pipeline. The extrusion plate 10 on the protective cover 9 surrounds and clamps the pipeline. The elastic component can buffer the rotation of the protective cover 9 when it is under pressure.

[0035] like Figure 6As shown, the elastic component includes an elastic frame 13, a sliding groove 14, a sliding shaft 15, a sliding rod 16 and a sliding rod 2 17. The elastic frame 13 is arranged on the protective cover 9, the sliding groove 14 is opened on the elastic frame 13, the sliding shaft 15 is slidably arranged in the sliding groove 14, the output end of the driving cylinder 12 is rotatably connected to the sliding shaft 15, the sliding rod 1 16 is arranged on the elastic frame 13, the sliding rod 2 17 is slidably connected to the sliding rod 1 16, the sliding rod 2 17 is rotatably connected to the sliding shaft 15, and the sliding rod 1 16 and the sliding rod 2 17 are sleeved with a spring 2 18. When the pipeline releases pressure toward both sides, the pressure causes an impact on the protective cover 9. At this time, since the length of the output end of the driving cylinder 12 remains unchanged, the sliding shaft is in the sliding groove. When the protective cover 9 is subjected to the impact of pressure and deflected, the elasticity of the sliding shaft 15 by the spring 2 18 is buffered to a certain extent, so that the protective cover 9 can be rotated in a small range. This rotation can make the gap between the two protective covers 9 for pressure relief change to a certain extent according to the pressure, so as to avoid the impact of the internal part of the protective cover 9 from causing damage. However, when the pressure is too high, the protective cover 9 cannot be rotated any further after it is rotated to the maximum angle, so as to avoid the pressure spreading to the surroundings, thereby protecting the surroundings and reducing the possibility of damage to the buffer mechanism.

[0036] In summary, the working principle of this pipeline pressure test device is:

[0037] Fix the two docking nozzles 2 on the two ends of the pipeline, connect the docking nozzles 2 to the external pressure test pump, place the pipeline on the support plate 4, the pipeline presses the support plate 4 and the support frame 3, the support frame 3 moves downward, the support frame 3 squeezes the support rod 8, the support rod 8 pushes the slide bar 7 to slide towards the stable frame 5, the slide bar 7 squeezes the spring 1 6, at this time the support plate 4 squeezes the pressing groove 11, the output end of the drive cylinder 12 extends to push the protective cover 9 to rotate on the support plate 1, when the squeezing plate 10 contacts the pipeline, the support plate 4 moves downward under the action of the gravity of the pipeline into the pressing groove 11, at this time the support plate 4 and the squeezing plate 10 clamp the pipeline, the pressure test pump pressurizes the pipeline, when there is a fault point on the pipeline and it bursts, the pressure of the pipeline impacts the two protective covers 9, this At the same time, the two protective covers 9 rotate to both sides, the spring 2 18 is compressed and shortened, the sliding rod 16 and the sliding rod 2 17 slide close to each other, and the sliding shaft 15 slides toward the sliding rod 16 on the sliding groove 14. When the sliding shaft 15 slides on the sliding groove 14 to one end close to the sliding rod 16, the sliding shaft 15 stops sliding, and the output end of the driving cylinder 12 supports the protective cover 9 through the sliding shaft 15. At the same time, when the protective cover 9 rotates to both sides under the action of the impact, the pressing groove 11 pushes the support plate 4 upward as the protective cover 9 rotates upward, and the support plate 4 pushes the pipeline upward. At the same time, the gravity of the pipeline can reduce the rotation angle of the protective cover 9 on the one hand, and the driving cylinder 12 rotates on the support plate 1, and the pressure released by the pipeline is released through the upper part of the pipeline to prevent damage to the surrounding staff.
