Abstract
Description
Technical Field
[0001] This invention relates to the field of chain inspection, and more particularly to an intelligent quality inspection device for mining chains. Background Technology
[0002] Mining chains consist of multiple links. During production, mining chains require tensile strength testing to ensure they meet requirements. During testing, when a link breaks, high-speed fragments fly in all directions. Although existing technology uses enclosures to protect personnel, the flying fragments inside the enclosures can damage clamps, hydraulic cylinders, and other testing equipment, thus reducing the lifespan of the equipment. Furthermore, the environment inside mines is harsh, containing significant amounts of moisture, dust, debris particles, and even corrosive environments like salt spray. Existing testing equipment cannot simulate the performance of the chain after use in a real-world environment, presenting significant limitations. Summary of the Invention
[0003] To overcome the drawback that when a chain link breaks, high-speed flying fragments will scatter in all directions, damaging the clamps, hydraulic cylinders, and other testing equipment, thereby reducing the service life of the testing equipment, this invention provides an intelligent quality testing device for mining chains.
[0004] Technical Solution: A smart quality detection device for mining chains includes a workbench, mounting rods, hydraulic cylinders, clamps, and connecting frames. The workbench is fixedly connected to two mounting rods; each mounting rod is fixedly connected to a hydraulic cylinder; each hydraulic cylinder's telescopic end is fixedly connected to a connecting frame; each connecting frame is connected to two clamps, and each clamp contains a tension sensor; the device also includes a drive assembly and protective cylinders; each connecting frame is fixedly connected to several spring rods; the telescopic ends of all spring rods on the same connecting frame are jointly fixedly connected to a push plate; each push plate has a cross groove; each push plate is fixedly connected to a diaphragm located within the cross groove; the workbench is connected to the drive assembly; the drive assembly is connected to two protective cylinders, and the hydraulic cylinders, clamps, connecting frames, spring rods, and push plates are located within their respective protective cylinders; each push plate is fixedly connected to several densely distributed bristles, and these bristles contact the inner wall of the protective cylinder.
[0005] Optionally, the drive assembly includes an electric guide rail and a moving block I; the worktable is fixedly connected to the electric guide rail; the moving block I is slidably connected to the electric guide rail, and the moving block I is fixedly connected to the protective cylinder.
[0006] Optionally, it also includes a hollow tube; one of the protective cylinders is fixed to the hollow tube.
[0007] Optionally, a filter screen is provided at the inlet of the hollow tube.
[0008] Optionally, it also includes a movable block II and a collection hopper; the movable block II is slidably connected to an electric guide rail; the movable block II is connected to the collection hopper.
[0009] Optionally, it also includes elastic tabs; each protective cylinder has several elastic tabs fixed to its inner wall.
[0010] Optionally, the protective sleeve is made of alloy steel.
[0011] Optionally, it also includes an annular guide rail, a slider, an electric push rod, a motor, and a wire brush; the movable block II is fixedly connected to the annular guide rail; the annular guide rail is slidably connected to the slider, and the slider is fixedly connected to the movable block II; the movable block II is fixedly connected to the electric push rod; the telescopic end of the electric push rod is fixedly connected to the motor; and the output shaft of the motor is connected to the wire brush.
[0012] Optionally, the motor's output shaft is detachably connected to the wire brush.
[0013] Optionally, it also includes a jet pipe; the telescopic end of the electric actuator is fixedly connected to the jet pipe.
[0014] The beneficial effects of this invention are: when the chain link suddenly breaks, the push plate blocks the high-speed flying fragments. After the flying fragments hit the push plate, the spring rod buffers and unloads the force on the push plate. At the same time, the diaphragm prevents the flying fragments from passing through the cross groove and damaging the clamp, thereby protecting the hydraulic cylinder, clamp and connecting frame, and avoiding direct damage to the hydraulic cylinder, clamp and connecting frame by the fragments.
[0015] In actual environmental testing, the protective cylinder is separated by densely distributed brushes that adhere to the inner wall of the protective cylinder, preventing salt spray from flowing into the gap between the push plate and the inner wall of the protective cylinder. The diaphragm prevents the salt spray from passing through the cross groove and contacting the hydraulic cylinder, clamp, and connecting frame, thus avoiding corrosion of the hydraulic cylinder, clamp, and connecting frame by the salt spray.
[0016] By controlling the motor to start, the output shaft of the motor drives the wire brush to rotate at high speed. Then, the electric push rod is controlled to move the connected components upward until the rotating wire brush contacts the surface of the chain link. Next, the circular guide rail is controlled to make the slider drive the electric push rod and the wire brush to rotate on the surface of the chain link, thereby generating friction between the steel wire brush and the surface of the chain link. This causes the wire brush to rub and polish the surface of the chain link. After that, the chain link is subjected to salt spray testing to make the test results more consistent with actual use.

Detailed Implementation
[0019] The embodiments of the present invention will be described below with reference to the accompanying drawings.
[0020] Example 1: A smart quality detection device for mining chains, such as... Figures 1-5 As shown, it includes a workbench 1, mounting rods 2, hydraulic cylinders 3, clamps 4, and connecting frames 6; the workbench 1 is fixedly connected to two mounting rods 2; each mounting rod 2 is bolted to a hydraulic cylinder 3; each extension end of each hydraulic cylinder 3 is fixedly connected to a connecting frame 6; each connecting frame 6 is connected to two clamps 4, and a tension sensor is installed inside the clamps 4; It also includes a drive assembly, a protective cylinder 103, a spring rod 201, a push plate 202, brush thorns 203, and a diaphragm 205; each connecting frame 6 is fixedly connected to several spring rods 201; the telescopic ends of all spring rods 201 located on the same connecting frame 6 are fixedly connected to a push plate 202; each push plate 202 has a cross groove 21; each push plate 202 is fixedly connected to a diaphragm 205, and the diaphragm 205 is located in the cross groove 21; the worktable 1 is connected to the drive assembly; the drive assembly is connected to two protective cylinders 103, and the hydraulic cylinder 3, the clamp 4, the connecting frame 6, the spring rods 201, and the push plate 202 are located in the corresponding protective cylinders 103; each push plate 202 is fixedly connected to several densely distributed brush thorns 203, and the brush thorns 203 are in contact with the inner wall of the protective cylinder 103.
[0021] The drive assembly includes an electric guide rail 101 and a moving block I 102; the worktable 1 is bolted to the electric guide rail 101; the electric guide rail 101 is slidably connected to the moving block I 102, and the moving block I 102 is fixedly connected to the protective cylinder 103.
[0022] It also includes a hollow tube 204; one of the protective cylinders 103 is fixedly connected to the hollow tube 204.
[0023] The inlet of the hollow tube 204 is equipped with a filter screen to protect the inlet of the hollow tube 204 and prevent splashing fragments from entering the inlet of the hollow tube 204 and causing blockage.
[0024] It also includes a movable block II 104 and a collection hopper 1020; the movable block II 104 is slidably connected to the electric guide rail 101; the movable block II 104 is connected to the collection hopper 1020.
[0025] It also includes elastic plates 1014; each inner wall of the protective cylinder 103 is fixed with several elastic plates 1014, which buffer and unload the fragments that fly when the chain link 5 breaks, so as to prevent the high-speed flying fragments from directly hitting the inner wall of the protective cylinder 103 and damaging the protective cylinder 103.
[0026] The protective sleeve 103 is made of alloy steel, which improves its impact resistance and thus extends its service life.
[0027] To face Figure 1 Using the direction as a reference, the external pump is connected to the hollow tube 204. During quality inspection, a chain sample consisting of five links 5 is taken for testing. In use, the chain consisting of five links 5 to be tested is placed horizontally by the operator. Initially, the two links 5 at the rightmost and leftmost ends pass through the cross grooves 21 of the corresponding push plates 202 and are fixed on the corresponding two clamps 4. After the chain consisting of multiple links 5 to be tested is fixed on the two clamps 4 by the operator, the electric guide rail 101 is controlled to make the two moving blocks I 102 drive the corresponding protective cylinders 103 to move towards each other until the two protective cylinders 103 are tightly fastened. This protects the broken links 5 during the testing process. Then, the two hydraulic cylinders 3 are controlled to make the connecting frame 6 slowly pull the corresponding clamps 4 to move in opposite directions, so that the two clamps 4 continuously apply tension to the links 5. The tension sensor inside the clamps 4 detects the tension when the links 5 break, thereby evaluating whether the tensile performance of the links 5 is qualified.
[0028] When the chain link 5 suddenly breaks, the push plate 202 blocks the high-speed flying debris. After the flying debris hits the push plate 202, the spring rod 201 buffers and relieves the force on the push plate 202. At the same time, the diaphragm 205 prevents the flying debris from passing through the cross groove 21 and damaging the clamp 4, thereby protecting the hydraulic cylinder 3, the clamp 4 and the connecting frame 6, and preventing the debris from directly damaging the hydraulic cylinder 3, the clamp 4 and the connecting frame 6.
[0029] Considering the typically strong corrosiveness of mining environments and the complex and diverse corrosive factors, chains are used in corrosive environments, as well as in high-temperature summers and low-temperature winters. Existing testing equipment cannot simulate the performance of chains under actual environmental conditions. Therefore, after the chain link 5 is fixed to the clamp 4, the two protective cylinders 103 come into contact with each other, with their inner walls tightly sealed to enclose the testing environment. Next, an external pump is controlled to deliver moisture through a hollow tube 204 into the enclosed environment formed by the two protective cylinders 103, placing the chain link 5 in a relatively humid environment. Then, the hydraulic cylinder 3 is controlled to cause the connecting frame 6 to drive the clamp 4 to apply tension to the chain link 5, thus testing the tensile strength of the chain link 5 in the humid environment. Following this, the external pump is controlled to deliver salt spray through the hollow tube 204 into the enclosed environment formed by the two protective cylinders 103, placing the chain link 5 in a relatively salt spray environment. Then, the hydraulic cylinder 3 is controlled to cause the connecting frame 6 to drive the clamp 4 to apply tension to the chain link 5, thus testing the tensile strength of the chain link 5 in the salt spray corrosive environment. The salt spray and humid environments are then tested. After the test is completed, first control the electric guide rail 101 to move the two moving blocks I 102 away from each other, and manually remove the water vapor and salt spray remaining on the inner wall of the protective cylinder 103 to avoid residual water vapor and salt spray leading to subsequent high and low temperature environment tests. Then, control the electric guide rail 101 to move the two moving blocks I 102 closer to each other until they make contact. Then, control the external pump to deliver high temperature gas into the closed environment formed by the two protective cylinders 103 through the hollow tube 204. The chain link 5 is placed in a high-temperature environment. Then, the hydraulic cylinder 3 is controlled to apply tension to the chain link 5 using the clamp 4 to test the tensile performance of the chain link 5 in the high-temperature environment. After the high-temperature environment test is completed and the chain link 5 is restored to room temperature, the external pump is controlled to deliver low-temperature gas to the closed environment formed by the two protective cylinders 103 through the hollow tube 204. This places the chain link 5 in a low-temperature environment. Then, the hydraulic cylinder 3 is controlled to apply tension to the chain link 5 using the clamp 4 to test the tensile performance of the chain link 5 in the low-temperature environment, thereby quickly switching the test environment.
[0030] In actual environmental testing, the protective cylinder 103 is separated by densely distributed brush 203 adhering to the inner wall of the protective cylinder 103, preventing salt spray from flowing into the gap between the push plate 202 and the inner wall of the protective cylinder 103. The diaphragm 205 prevents salt spray from passing through the cross groove 21 and contacting the hydraulic cylinder 3, clamp 4 and connecting frame 6, thus avoiding corrosion of the hydraulic cylinder 3, clamp 4 and connecting frame 6 by the salt spray.
[0031] After the inspection is completed, any broken chain links 5 will fall into the two protective cylinders 103. At this time, the electric guide rail 101 is controlled to move the moving block II 104 to drive the collection bucket 1020 to move until the collection bucket 1020 is located at the joint of the two protective cylinders 103. Then, the electric guide rail 101 is controlled to move the two moving blocks I 102 to drive the corresponding protective cylinders 103 to move in opposite directions until the two protective cylinders 103 separate from each other. When the two protective cylinders 103 separate, the protective cylinders 103 and the brush 203 generate relative movement, and then the brush 203 brushes out the debris remaining in the protective cylinders 103, improving the cleaning efficiency.
[0032] In order to identify the source of the fragments after the chain link 5 breaks, the quality of the chain link 5 needs to be analyzed and improved. The chain link 5 needs to be painted separately. Therefore, before the test, different pigments are applied to different chain links 5, so that the surfaces of the three chain links 5 are covered with different colors. This makes it easier to identify the source of the fragments by the color applied to the fragments after the chain link 5 breaks.
[0033] Example 2, based on Example 1, such as Figure 2 and Figure 5 As shown, it also includes an annular guide rail 105, a slider 106, an electric push rod 1016, a motor 1017, and a wire brush 1018; the moving block II 104 is fixedly connected to the annular guide rail 105; the annular guide rail 105 is slidably connected to the slider 106, and the slider 106 is fixedly connected to the moving block II 104; the moving block II 104 is fixedly connected to the electric push rod 1016; the telescopic end of the electric push rod 1016 is fixedly connected to the motor 1017; the output shaft of the motor 1017 is connected to the wire brush 1018.
[0034] The output shaft of the motor 1017 is detachably connected to the wire brush 1018. After the wire brush 1018 cleans the chain link 5 for a long time, it will wear out. Therefore, the output shaft of the motor 1017 and the wire brush 1018 are detachably connected to facilitate easy manual replacement of the wire brush 1018.
[0035] It also includes a jet pipe 1019; the telescopic end of the electric push rod 1016 is fixedly connected to the jet pipe 1019.
[0036] In this embodiment, an external air pump is connected to the jet pipe 1019. To simulate the corrosion resistance of the chain link 5 after friction with other metals during operation, before the salt spray test, the motor 1017 is started, and the output shaft of the motor 1017 drives the wire brush 1018 to rotate at high speed. Then, the electric push rod 1016 is controlled to move the connected component upward until the rotating wire brush 1018 contacts the surface of the chain link 5. Then, the annular guide rail 105 is controlled to make the slider 106 drive the electric push rod 1016 and the wire brush 1018 to rotate on the surface of the chain link 5, thereby causing friction between the steel wire brush 1018 and the surface of the chain link 5, and thus the wire brush 1018 rubs and polishes the surface of the chain link 5. After that, the chain link 5 is tested for salt spray, so that the test results are more in line with actual use.
[0037] Meanwhile, considering that the residual debris and other impurities after grinding the chain link 5 will affect the salt spray adhesion effect, the surface of the chain link 5 needs to be cleaned before the salt spray test after grinding with the wire brush 1018. The external air pump is started to deliver gas into the air jet pipe 1019. After the gas is sprayed out through the air jet pipe 1019, it cleans the oil and rust on the surface of the chain link 5. During the cleaning process, the electric guide rail 101 is controlled to make the moving block II 104 drive the slider 106 and its connected components to move horizontally, so that the air jet pipe 1019 cleans all the chain links 5.
