Description

Technical Field

[0001] This utility model relates to the field of steel pipe flaw detection technology, and in particular to a magnetic particle flaw detection device for galvanized steel pipes. Background Technology

[0002] Galvanized steel pipes are steel pipes coated with a layer of zinc through hot-dip galvanizing or electro-galvanizing, which serves to prevent corrosion and rust. Magnetic particle testing equipment is a device used to detect surface and near-surface defects in ferromagnetic materials. After galvanizing, galvanized steel pipes need to be inspected for the presence of gaps on their surface.

[0003] Existing technologies, such as patent CN216926683U, disclose a magnetic particle flaw detection device for seamless steel pipe inspection. This patent uses a flaw detector and also includes a base plate. The top surface of the base plate is provided with two sets of positioning components for positioning the pipe. The base plate is provided with a sliding component for driving one set of positioning components to slide along the extension direction of the pipe. The other set of positioning components is slidably connected to the base plate through a sliding component. A flaw detection bracket is provided between the two positioning components, and a flaw detection cylinder is rotatably connected to the flaw detection bracket. This utility model device solves the problems of traditional magnetic particle flaw detectors having a simple shape and structure, requiring manual adjustment of the position of the magnetic particle flaw detector during use, and thus having certain limitations, time-consuming and labor-intensive, in order to detect flaws in seamless steel pipes of different lengths.

[0004] In daily operation, during the spray testing of steel pipes, the existing equipment has a problem: due to excessive spraying force, the material is easily splashed out of the chamber after contacting the surface of the steel pipe, and spills around the equipment, causing pollution to the surrounding environment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where material splashes out of the casing during the spraying process, causing pollution to the surrounding environment. This invention proposes a magnetic particle inspection device for galvanized steel pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic particle inspection device for galvanized steel pipes, comprising a housing, a power unit, a connecting frame, a nozzle, and a cylinder. The power unit is fixedly connected inside the housing, the connecting frame is fixedly connected to the side of the housing, the nozzle is fixedly connected inside the connecting frame, and the cylinder is fixedly connected inside the housing. A blocking assembly is fixedly installed inside the housing, the blocking assembly comprising a blocking plate and a backing plate. The blocking plate is slidably disposed on the inner wall of the housing, the backing plate is fixedly connected to the side of the cylinder, and a connecting plate is fixedly connected to the side of the blocking plate near the cylinder. The backing plate abuts against the lower surface of the connecting plate. A connecting block is fixedly connected to the inner wall of the housing, a sliding rod is fixedly connected inside the connecting block, and a connecting arm is slidably connected to the surface of the sliding rod.

[0007] A fixing block is fixedly connected to the end of the connecting arm away from the slide rod. The fixing block is fixedly connected to the side of the baffle plate close to the connecting plate. By setting the connecting arm, the baffle plate can be limited to move, reducing the difficulty of the baffle plate moving smoothly during use.

[0008] A first spring is sleeved and connected to the surface of the slide rod.

[0009] One end of the first spring is fixedly connected to the surface of the connecting arm, and the end of the first spring away from the connecting arm is fixedly connected to the lower surface of the connecting block. The first spring is provided to facilitate the application of a restoring force to the connecting arm.

[0010] An auxiliary component is installed inside the housing. The auxiliary component includes a filter frame and a pull plate. The pull plate is fixedly connected to the upper surface of the filter frame and inserted into the surface of the housing. The filter frame is inserted into the interior of the housing. By setting the pull plate, the filter frame can be limited in movement, reducing the difficulty of moving and cleaning the filter frame during use.

[0011] A first filter plate is fixedly connected inside the filter frame, and a second filter plate is fixedly connected inside the filter frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up a blocking component, when inspecting a steel pipe, a cylinder moves the steel pipe upwards, and then a power unit clamps and rotates the steel pipe to magnetize it. Then, a nozzle inside the connecting frame sprays material onto the surface of the steel pipe. When the cylinder moves, it drives the abutment plate to move, which in turn moves the connecting plate. The moving connecting plate then moves the blocking plate, causing the connecting arm to move on the surface of the sliding rod. When the connecting arm moves, it causes the first spring to deform and generate elastic force. By setting up the blocking component, the splashing material during the spraying process is effectively blocked, preventing it from splashing out of the housing. This reduces the pollution of the surrounding environment caused by splashing material during the spraying process, as is common in existing equipment. This blocking component effectively blocks splashing material, improving the cleanliness of the equipment.

[0014] In this invention, by setting an auxiliary component, when the equipment filters the material after spraying, the sprayed material passes through the first and second filter plates inside the filter frame to filter impurities in the sprayed material. By setting the auxiliary component, impurities in the material after spraying are effectively filtered, reducing the situation where existing equipment easily carries impurities adsorbed on the surface of the steel pipe in the material after spraying, which affects the secondary use of the material. This auxiliary component can effectively filter impurities on the surface of the steel pipe in the used sprayed material, improving the practicality of the equipment. Attached Figure Description

The power unit 2 is fixedly connected inside the housing 1, the connecting frame 3 is fixedly connected to the side of the housing 1, the nozzle 4 is fixedly connected inside the connecting frame 3, and the cylinder 5 is fixedly connected inside the housing 1.

[0022] The following section will explain the specific settings and functions of the blocking component 6 and the auxiliary component 7.

[0023] In this embodiment: a blocking assembly 6 is fixedly installed inside the housing 1. The blocking assembly 6 includes a blocking plate 61 and a backing plate 63. The blocking plate 61 is slidably installed on the inner wall of the housing 1. The backing plate 63 is fixedly connected to the side of the cylinder 5. A connecting plate 62 is fixedly connected to the side of the blocking plate 61 near the cylinder 5. The backing plate 63 abuts against the lower surface of the connecting plate 62. A connecting block 64 is fixedly connected to the inner wall of the housing 1. A sliding rod 66 is fixedly connected inside the connecting block 64. A connecting arm 65 is slidably connected to the surface of the sliding rod 66.

[0024] Specifically, a fixing block 68 is fixedly connected to the end of the connecting arm 65 away from the slide bar 66, and the fixing block 68 is fixedly connected to the side of the blocking plate 61 near the connecting plate 62.

[0025] In this embodiment: by setting the connecting arm 65, the blocking plate 61 can be limited to move, reducing the situation where the blocking plate 61 is difficult to move smoothly when the equipment is in use.

[0026] Specifically, a first spring 67 is sleeved and connected to the surface of the slide rod 66.

[0027] Specifically, one end of the first spring 67 is fixedly connected to the surface of the connecting arm 65, and the end of the first spring 67 away from the connecting arm 65 is fixedly connected to the lower surface of the connecting block 64. The first spring 67 is provided to facilitate the application of a restoring force to the connecting arm 65.

[0028] In this embodiment: An auxiliary component 7 is installed inside the housing 1. The auxiliary component 7 includes a filter frame 71 and a pull plate 72. The pull plate 72 is fixedly connected to the upper surface of the filter frame 71. The pull plate 72 is inserted and connected to the surface of the housing 1. The filter frame 71 is inserted and connected to the inside of the housing 1.

[0029] In this embodiment: by setting the pull plate 72, the filter frame 71 can be limited to move, reducing the difficulty of moving and cleaning the filter frame 71 during use.

[0030] Specifically, a first filter plate 73 is fixedly connected inside the filter frame 71, and a second filter plate 74 is fixedly connected inside the filter frame 71.

[0031] Working principle: When inspecting steel pipes, cylinder 5 moves the steel pipe upwards, and then power unit 2 clamps and rotates the steel pipe to magnetize it. Then, the nozzle 4 inside the connecting frame 3 sprays material onto the surface of the steel pipe. When cylinder 5 moves, it drives the abutment plate 63 to move, which in turn drives the connecting plate 62 to move. When the connecting plate 62 moves, it drives the baffle plate 61 to move, which in turn drives the connecting arm 65 to move on the surface of the slide rod 66. When the connecting arm 65 moves, it drives the first spring 67 to displace and deform, generating elastic force. By setting the blocking component 6, the splashed material during the spraying process is effectively blocked, which prevents the splashed material from splashing out of the box 1. This reduces the pollution of the surrounding environment caused by the sprayed material easily splashing out of the box 1 during the spraying process of existing equipment. This blocking component 6 can effectively block the splashed sprayed material and improve the cleanliness of the equipment.

[0032] When the equipment filters the material after spraying, the sprayed material passes through the first filter plate 73 and the second filter plate 74 inside the filter frame 71 to filter impurities in the sprayed material. By setting the auxiliary component 7, the equipment can effectively filter impurities in the material after spraying, reducing the situation where the material easily carries impurities adsorbed on the surface of the steel pipe when recycling the material after spraying, which affects the reuse of the material. This auxiliary component 7 can effectively filter impurities on the surface of the steel pipe in the used sprayed material, improving the practicality of the equipment.
