[0002] Salt spray test is an environmental test that mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. At present, the test of pipeline anti-rust performance is usually carried out by spraying salt spray on the pipeline surface so that the pipeline is fully in contact with the salt spray, so as to test the pipeline's anti-rust performance.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN209559730U discloses a salt spray tester for exhaust pipe production, wherein the pipe to be tested is horizontally clamped and fixed inside a test box by a fixing device, and the salt spray settles on the upper side of the pipe to be tested. When a certain amount of salt spray gathers on the upper side of the pipe to be tested, it will flow downward along its outer side due to gravity, and drip after gathering on the bottom side, resulting in poor uniformity of salt spray distribution on the outer side of the pipe to be tested, thereby affecting the test effect.

[0004] Therefore, it is necessary to design an anti-rust performance testing device that can improve the uniformity of salt spray distribution on the outside of the pipeline and ensure the test effect to solve the current technical problems. Summary of the invention

[0010] A frame plate is provided inside the inner box below the roller, and the four sides of the frame plate are fixedly connected to the inner side of the inner box.

[0011] The frame plate is evenly provided with water-permeable holes.

[0012] The roller comprises a roller body, and a plurality of anti-slip rings are evenly sleeved on the outer side of the roller body along the axial direction thereof.

[0013] The outer side of the anti-skid ring is provided with anti-skid protrusions in a circumferential array, and the anti-skid protrusions and the anti-skid ring are an integral structure.

[0022] like Figure 1 and 2 As shown, the rust-proof performance testing device comprises an outer box body 1, a control cabinet 3 is arranged on one side of the outer box body 1, a cover body 2 is arranged on the top of the outer box body 1, an inner box body 4 is arranged inside the outer box body 1, a spray device 5 is arranged in the center of the inner box body 4, and a plurality of groups of roller assemblies are symmetrically arranged on both sides of the inner box body 4, the roller assembly has two rollers 7 rotatably connected with the side surfaces of the inner box body 4, and a roller driving mechanism 8 for driving the rollers 7 to rotate synchronously in the same direction is arranged on the outer side of the inner box body 4; in this embodiment, when performing a salt spray test, the two ends of the pipeline to be tested are respectively placed on two roller assemblies corresponding to the two sides of the inner box body 4, and the salt spray is sprayed outward from the spray device and evenly settles downward, and the roller driving mechanism 8 drives the rollers 7 to rotate synchronously in the same direction at a uniform speed, and when the rollers 7 drive the pipeline to be tested placed above them to rotate at a uniform speed, the salt spray is evenly settled on the outer surface of the pipeline to be tested, thereby improving the uniformity of the distribution of the salt spray on the outer side of the pipeline and ensuring the test effect.

[0023] In some embodiments, as a specific implementation of the roller drive mechanism 8, the roller drive mechanism 8 has a drive shaft 82 rotatably arranged on the outside of one end of the inner box body 4, and a drive motor 81 is arranged on the drive shaft 82 to drive it to rotate. A driven sprocket 84 coaxially connected to the roller 7 is arranged on the outside of the inner box body 4, and a driving sprocket 83 corresponding to the driven sprocket 84 is arranged at the end of the drive shaft 82. The driving sprocket 83 and the driven sprocket 84 are connected by a transmission chain 85. The driven sprockets 84 at the ends of the roller 7 are evenly connected to the same transmission chain 83. The driving motor 81 drives the drive shaft 82 to rotate, and the drive shaft 82 drives the driving sprockets 83 at both ends thereof to rotate synchronously in the same direction. At the same time, the two driving sprockets 83 drive the two transmission chains 85 to rotate synchronously in the same direction, and the rollers 7 on both sides of the inner box body 4 are driven to rotate synchronously in the same direction at a uniform speed through the two transmission chains 85.

[0024] As a specific installation method of the drive shaft 82 , a shaft seat 86 is symmetrically rotatably arranged on the drive shaft 82 , and the shaft seat 86 is fixedly arranged on the outer side of one end of the inner box body 4 , and the drive shaft 82 is rotatably mounted on the outer side of one end of the inner box body 4 through the shaft seat 86 .

[0025] In some embodiments, the driving motor 81 is fixedly disposed on the outer side of one end of the inner box body 4, and the driving motor 81 is a reduction motor.

[0026] In some embodiments, a frame plate 6 is provided on the inner side of the inner box body 4 below the roller 7, and the frame plate 6 is fixedly connected to the inner side of the inner box body 4 on all sides. The setting of the frame plate 6 can prevent the tube body to be tested from sliding to the inner bottom of the inner box body when the tube body to be tested is placed on the roller assembly, making it difficult to take out.

[0027] In some embodiments, water-permeable holes 61 are evenly formed on the frame plate 6 , and the salt mist above the frame plate 6 can be settled into the lower part thereof through the water-permeable holes 61 for easy collection.

[0028] In some embodiments, Figure 3 As shown, the roller 7 has a roller body 71, and a plurality of anti-skid rings 73 are evenly mounted on the outer side of the roller body 71 along its axial direction. The anti-skid rings 73 can increase the friction between the pipe body to be tested and the roller 7, thereby avoiding slipping between the pipe to be tested and the roller 7 during the test. Specifically, an annular groove matching the anti-skid ring 73 is provided on the outer side of the roller 7.

[0029] In some embodiments, the outer side of the anti-slip ring 73 has anti-slip protrusions 74 in a circular array. The anti-slip protrusions 74 and the anti-slip ring 73 are an integrated structure. The provision of the anti-slip protrusions 74 can further increase the friction between the pipe body and the roller 7, thereby avoiding slippage between the pipe to be tested and the roller 7 during testing.

[0030] As a more specific implementation of the anti-slip ring 73, the anti-slip ring 73 is a rubber ring or a silicone ring.

[0031] In some embodiments, a baffle plate 72 is fixedly and concentrically arranged on one end of the roller body 71 close to the driven sprocket 84. When the pipe to be tested is placed on the roller 7, the end of the pipe to be tested abuts against the side of the baffle plate 72. When rotating, the pipe to be tested can be prevented from contacting the inner box body 4, thereby avoiding wear on the inner box body 4. Specifically, the baffle plate 72 and the roller body 71 are an integral structure; the roller body 71 and the driven sprocket 84 are coaxially connected.
