Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a detection mechanism for the strength of ship pipelines. Background Art

[0002] Pipeline strength testing is to use higher air pressure to check the tightness of the pipeline. The test pressure depends on the pipeline gas pressure level and the pipeline material. Under normal circumstances, the test pressure is 1.5 times the design gas pressure, but the steel pipe shall not be lower than 0.3Mpa, the plastic pipe shall not be lower than 0.1Mpa, and the cast iron pipe shall not be lower than 0.05Mpa.

Example

[0023] See also Figure 1 - Figure 4, the utility model provides a technical solution: a ship pipeline strength detection mechanism, comprising: a pipe to be tested 1, the pipe to be tested 1 is used for transporting materials;

[0024] A detection device 2, the detection device 2 is used to detect the strength of the tube 1 to be tested, and the outer surface of the detection device 2 is rotatably connected to the inner wall of the tube 1 to be tested;

[0025] The detection device 2 includes a main board 11, a connecting rod 12 is fixedly connected at the center of the outer surface of the main board 11, a pneumatic rod 13 is fixedly connected to the outer surface of the connecting rod 12, a partition 14 is fixedly connected to the end of the connecting rod 12 away from the main board 11, a hydraulic rod 18 is fixedly connected to the inner wall of the partition 14, a sliding rod 16 is fixedly connected to the top of the hydraulic rod 18, a ball 15 is rotatably connected to the inner wall of the sliding rod 16, a supporting spring 17 is fixedly connected to the bottom end of the sliding rod 16, and the hydraulic rod 18 works to make the sliding rod 16 at the top slide in the partition 14, so that the ball 15 is rotated and connected to the inner wall of the sliding rod 16, and the supporting spring 17 is fixedly connected to the bottom end of the sliding rod 16. The ball 15 abuts against the inner wall of the tube 1 to be tested. Since the center lines of the two hydraulic rods 18 in the partition 14 coincide with each other and the extension of the hydraulic rods 18 is the same, the slide bar 16 connected to the hydraulic rod 18 moves the ball 15 to the same distance outside the partition 14, which can ensure that the center line of the partition 14 and the center line of the inner diameter of the tube 1 to be tested are on the same horizontal plane. The outer surface of the partition 14 away from the main board 11 is fixedly connected with a cleaning device 3. The cleaning device 3 first enters the tube 1 to be tested to clean up the dirt in the pipeline to avoid affecting the detection of the inner wall of the pipeline by the detection pneumatic rod 13.

[0026] The outer surface of the ball 15 is rotatably connected to the inner wall of the tube to be tested 1, the outer surface of the slide rod 16 is slidably connected to the inner wall of the partition 14, and the outer surface of the slide rod 16 is also slidably connected to the inner wall of the main board 11. The end of the support spring 17 away from the slide rod 16 is fixedly connected to the inner surface of the main board 11, and the outer surface of the support spring 17 is also fixedly connected to the inner wall of the partition 14. The ball 15 in the slide rod 16 in all directions on the partition 14 is pressed against the inner wall of the tube to be tested 1 by the support spring 17. The cleaning device 3 includes a rotating motor 4, and the output end of the rotating motor 4 is fixedly connected to a rotating shaft 5, the outer surface of the rotating shaft 5 is fixedly connected to a fixing sleeve 6, the inner surface of the fixing sleeve 6 is fixedly connected to a tension spring 7, and the top of the tension spring 7 is fixedly connected to a scraper 8. The inner wall of the scraper 8 is provided with a water flow groove 9, and the inner wall of the scraper 8 is slidably connected to a water outlet component 10. The water outlet component 10 facilitates the cleaning agent in the scraper 8 to be thrown onto the inner wall of the pipe.

[0027] The outer surface of the water outlet component 10 is slidably connected to the inner wall of the rotating motor 4, the outer surface of the rotating motor 4 is fixedly connected to the outer surface of the partition 14, the inner wall of the fixed sleeve 6 is slidably connected to the outer surface of the scraper 8, the rotating motor 4 is turned on to rotate the rotating shaft 5, and the top of the scraper 8 is away from the rotating shaft 5 due to the centrifugal force generated by the rotation. The water outlet component 10 includes a wooden plug 19, the top of the wooden plug 19 is fixedly connected to a retaining ring 20, the bottom of the wooden plug 19 is fixedly connected to an elastic rope 21, and the end of the elastic rope 21 away from the wooden plug 19 is fixedly connected to a threaded sleeve 22, the inner wall of the threaded sleeve 22 is threadedly connected to the outer surface of the rotating shaft 5, and the outer surface of the threaded sleeve 22 is fixedly connected to the plug rod 2 3. The outer surface of the plug 23 is slidably connected to the inner wall of the rotary motor 4, and the outer surface of the wooden plug 19 is slidably connected to the inner wall of the scraper 8. The wooden plug 19 is stuck in the scraper 8, that is, the wooden plug 19 drives one end of the elastic rope 21 connected thereto to rotate with the rotating shaft 5. The plug 23 is inserted into the rotary motor 4, and the threaded sleeve 22 translates toward the fixed sleeve 6 on the rotating shaft 5 without rotating. The threaded sleeve 22 translates while winding around the elastic rope 21, and the length of the elastic rope 21 is reduced and drives the wooden plug 19 to slide in the scraper 8. The top of the scraper 8 is moved away from the rotating shaft 5 due to the centrifugal force generated by the rotation, so that the hole on the scraper 8 is opened, and the cleaning agent in the water flow trough 9 falls onto the inner wall of the tube 1 to be tested.

[0028] Working principle:

[0029] When in use, the operator fills the scraper 8 in the cleaning device 3 with cleaning agent, and then uses the wooden plug 19 to block the outlet on the scraper 8, and then first sends the cleaning device 3 in the detection device 2 into the tube 1 to be tested, and at the same time starts the rotating motor 4 to rotate the rotating shaft 5. Since the threaded sleeve 22 in the water outlet component 10 is threadedly connected to the rotating shaft 5, and the insertion rod 23 on the threaded sleeve 22 is inserted in the rotating motor 4, the threaded sleeve 22 translates toward the fixed sleeve 6 on the rotating shaft 5 without rotating. In addition, because the wooden plug 19 in the water outlet component 10 is stuck in the scraper 8, that is, the wooden plug 19 drives one end of the elastic rope 21 connected to it to rotate with the rotating shaft 5, the threaded sleeve 22 translates and wraps around the elastic rope 21. The length of the elastic rope 21 is reduced and drives the wooden plug 19 to slide in the scraper 8, and the top of the scraper 8 is away from the rotating shaft 5 due to the centrifugal force generated by the rotation, so that the hole on the scraper 8 is opened, and the wooden plug 19 will not fall off the scraper due to the obstruction of the retaining ring 20. 8. The cleaning agent in the water trough 9 falls onto the inner wall of the tube 1 to be tested, and the dirt on the inner wall is cleaned off by the top of the scraper 8. The operator continues to move the detection device 2. The partition 14 enters the tube first. The hydraulic rod 18 works to make the slide bar 16 at its top slide in the partition 14, so that the ball 15 hits the inner wall of the tube 1 to be tested. Since the center lines of the two hydraulic rods 18 in the partition 14 coincide and the elongation of the hydraulic rods 18 is the same, the slide bar 16 connected to the hydraulic rod 18 moves the ball 15 to the same distance outside the partition 14, which can ensure that the center line of the partition 14 and the center line of the inner diameter of the tube 1 to be tested are on the same horizontal plane. The balls 15 in the slide bars 16 evenly arranged on the partition 14 are pushed against the inner wall of the tube 1 to be tested by the support springs 17, and the gaps between the balls 15 are small, so the partition 14 can assist in pushing the fallen dirt forward, so that there is no dirt between the main board 11 and the partition 14 and the inner wall of the tube 1 to be tested.

[0030] After the rotating motor 4 stops working, the scraper 8 loses the centrifugal force and is retracted by the tension spring 7. The operator inflates the pneumatic rod 13 through the air supply hole on the main board 11 through the connecting rod 12. The extended section of the pneumatic rod 13 extends and lifts up the pipe in contact with it. During the inflation process, the operator observes the deformation degree of the pipe. Since the extended length of the pneumatic rod 13 is roughly the pressure range that the pipe is designed to withstand, before the pneumatic rod 13 is fully extended, the staff observes that the pipe is severely deformed or damaged, and the pipe strength test fails. When the pneumatic rod 13 is fully extended, the pipe deformation is small and not damaged, and the pipe strength test passes, thereby testing the pipe strength.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
