[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] A pipe quality testing device, such as Figures 1 to 3 As shown, it includes: a test chamber 1 and a rotating mounting plate 11. A through groove is provided on one side of the test chamber 1 to facilitate the loading and unloading of pipes, and a rotating heat insulation door 3 is rotatably installed on this side. The rotating heat insulation door 3 closes the test chamber 1 to facilitate aging tests.
[0024] The front of the test chamber 1 is fixedly equipped with a light-shielding and heat-insulating glass 2, and the back of the test chamber 1 is fixedly equipped with an aging tester 9. The aging tester 9 performs aging tests on the pipes. The front of the light-shielding and heat-insulating glass 2 is equipped with light-shielding aluminum foil cloth, which can block the light emitted by the aging tester 9 and reduce heat dissipation.
[0025] A mounting sleeve 4 is fixedly connected to the top of the testing chamber 1. A hardness tester 5 is slidably installed inside the mounting sleeve 4. The inner cavity of the mounting sleeve 4 penetrates the top of the testing chamber 1, so that the testing probe of the hardness tester 5 can be inserted into the testing chamber 1 to test the hardness of the pipe.
[0026] The bottom of the inner cavity of the mounting sleeve 4 is fitted with a protective rotating plate 10 via a coil spring. Figure 2 As shown, when the pipe is not being tested for hardness, the protective rotating plate 10 closes the inner cavity of the mounting sleeve 4 to facilitate aging experiments; when the pipe is being tested for hardness, the hardness tester 5 is pressed down directly so that the test probe of the hardness tester 5 extends into the test chamber 1.
[0027] The aging tester 9 does not perform pipe hardness testing during operation. When the aging tester 9 is turned off, pipe hardness testing can be performed. Therefore, during the pipe quality inspection process, hardness testing can be performed on the pipe at multiple points before, during and after the aging experiment, thereby improving the accuracy of pipe quality inspection.
[0028] The rotating mounting plate 11 is located inside the detection chamber 1, and the axis of the rotating mounting plate 11 is perpendicular to the side wall of the detection chamber 1. A connecting rotating cylinder 12 is fixedly connected to the side of the rotating mounting plate 11 away from the rotating heat insulation door 3. One end of the connecting rotating cylinder 12 penetrates one side wall of the detection chamber 1 and is rotatably connected to the detection chamber 1 through a bearing. A driven gear 13 is fixedly installed at the extended end of the connecting rotating cylinder 12.
[0029] A motor bracket 6 is fixedly installed on the bottom side of the test chamber 1 connected to the connecting drum 12. A drive motor 7 is fixedly installed on the top of the motor bracket 6. A drive gear 8 is fixedly installed on the output shaft of the drive motor 7. The drive gear 8 meshes with the driven gear 13.
[0030] The inner cavity of the connecting drum 12 passes through the rotating mounting plate 11, and the connecting shaft 14 is rotatably mounted in the inner cavity of the connecting drum 12. A control handle 16 is fixedly mounted on one end of the connecting shaft 14 near the drive motor 7, and a locking nut 15 is threaded onto the outer wall of the connecting shaft 14 at that end. The locking nut 15 is close to the connecting drum 12. When the locking nut 15 is tightly fitted with the connecting drum 12, the connecting shaft 14 and the connecting drum 12 are relatively fixed.
[0031] The other end of the connecting shaft 14 is welded with a connecting turntable 17. The connecting turntable 17 is located on the side of the rotating mounting plate 11 near the mounting sleeve 4, and a positioning square post 18 is integrally formed on the side of the connecting turntable 17 near the mounting sleeve 4. The positioning square post 18 is coaxial with the connecting turntable 17.
[0032] Multiple limiting plates 19 are equidistantly arranged on the outer wall of the positioning column 18. The limiting plates 19 are fixed to the connecting turntable 17 by bolts. A transmission threaded rod 20 is provided between two adjacent limiting plates 19. One end of the transmission threaded rod 20 is rotatably connected to the positioning column 18.
[0033] One end of the transmission threaded rod 20 is threadedly connected to the connecting slider 21, and the other end is fixedly installed with the driven bevel gear 24. A clamping pin 22 is fixedly installed on one side of the connecting slider 21. Multiple clamping pins 22 are inserted into the inside of the pipe and then move along the diameter of the pipe to fit against the inner wall of the pipe, thereby fixing the pipe.
[0034] A limit block 23 is provided on the side of the driven bevel gear 24 near the connecting slider 21. The limit block 23 is rotatably connected to the transmission threaded rod 20 and is fixedly connected to two adjacent limit plates 19.
[0035] Multiple driven bevel gears 24 are meshed with a fixed bevel gear ring 25. The fixed bevel gear ring 25 is fixedly connected to the rotating mounting plate 11 and is rotatably sleeved on the outer wall of the connecting turntable 17 to improve the stability of the connecting turntable 17.
[0036] Working principle:
[0037] Please refer to Figures 1 to 3 Assemble the device as shown in the figure;
[0038] In use, the pipe to be tested is first fitted onto the outside of multiple clamping posts 22. Then, the locking nut 15 is loosened, and the connecting shaft 14 is rotated clockwise by controlling the rotating handle 16. The connecting shaft 14 drives the connecting turntable 17 to rotate synchronously. The connecting turntable 17 drives the driven bevel gear 24 to rotate synchronously through the connecting transmission threaded rod 20. The driven bevel gear 24 meshes with the fixed bevel gear ring 25, which is fixedly connected to the rotating mounting plate 11, causing the driven bevel gear 24 to rotate counterclockwise. The driven bevel gear 24 rotates, causing the transmission threaded rod 20 to rotate counterclockwise, which in turn moves the connecting slider 21 away from the positioning square post 18, causing the clamping post 22 to fit against the inner wall of the pipe. After the pipe is clamped and fixed, the locking nut 15 is tightened, the drive motor 7 is started, and then the rotating mounting plate 11 is driven to rotate at a constant speed through the connecting rotating drum 12. The aging tester 9 is turned on to conduct the aging test. Before, during and after the aging test, the hardness of the pipe is tested at multiple points, while the drive motor 7 is kept off.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
