Description

Technical Field

[0001] This utility model relates to the field of magnetic flaw detectors, specifically a magnetic flaw detector for special equipment. Background Technology

[0002] A magnetic flaw detector is a device used for non-destructive testing, primarily for detecting surface and near-surface defects in ferromagnetic materials and their components.

[0003] In the comparative case, patent publication number CN216116105U, this utility model relates to a portable bracket for a special equipment testing instrument, including a mounting plate and a support portion for supporting the mounting plate. Two sets of clamping devices are symmetrically arranged on the mounting plate. Each set of clamping devices includes a first clamping plate, a second clamping plate, a return spring, and a telescopic rod. A sliding groove extending longitudinally from the inside to the side wall is formed on the upper surface of the mounting plate. A slide bar is fixedly mounted on the first clamping plate. A return spring and a telescopic rod are arranged in the sliding groove. One end of the return spring and the telescopic rod are fixedly connected to the slide bar, and the other end is fixedly connected to the side wall of the mounting plate. The second clamping plate is mounted on one end of the first clamping plate by a wing bolt. This utility model allows a small special equipment testing instrument to be placed between the two first clamping plates of the two sets of clamping devices. The first clamping plates clamp the instrument, and under the action of the return spring, the two first clamping plates drive the slide bar to slide within the sliding groove. This allows it to adapt to different models of small special equipment testing instruments and clamp their bottoms.

[0004] However, in implementing the relevant technology, the portable bracket of the aforementioned special equipment detector was found to have the following problems. In the comparative case, the first clamp is used for clamping, and under the action of the return spring, the two first clamps drive the slide bar to slide in the sliding groove, which can adapt to different models of small special equipment detectors and clamp their bottoms. The existing magnetic detection detector requires a tool to generate magnetizing current, and the tool and power supply are two separate entities that cannot be combined for carrying, which reduces the convenience of using the magnetic detection detector.

[0005] Therefore, the design of the magnetic detector needs to be modified to effectively prevent the problem that the magnetic detector needs to be paired with a tool to generate magnetizing current, but the tool and the power supply are two separate entities that cannot be combined for portability. Utility Model Content

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides a magnetic detection instrument for special equipment, comprising:

[0024] Power supply unit 1, electromagnetic yoke 2 is placed on the left side of power supply unit 1, and auxiliary mechanism 3 is fixedly connected to the left side of power supply unit 1;

[0025] The auxiliary mechanism 3 includes a placement box 31, an L-shaped tray 32, a cross plate 33, and a rectangular frame 34. The placement box 31 is fixedly connected to the left side of the power supply unit 1. The L-shaped tray 32 is movably connected to the front and back ends of the left side of the placement box 31. The right side of the L-shaped tray 32 extends into the interior of the placement box 31. The cross plate 33 is fixedly connected to the inside of the L-shaped tray 32 and located inside the placement box 31. The rectangular frame 34 is slidably connected to the top and bottom of the cross plate 33. The left and right sides of the rectangular frame 34 are fixedly connected to one side of the inner wall of the placement box 31. The connecting mechanism 4 is fixedly connected to the front end of the L-shaped tray 32 and located inside the placement box 31.

[0026] refer to Figure 4 The connecting mechanism 4 includes a sliding sleeve 41, a fixed rod 42, and a connecting rod 43. The sliding sleeve 41 is fixedly connected to the front end of the L-shaped tray 32 and inside the placement box 31. The fixed rod 42 is fixedly connected to the right side of the inner wall of the placement box 31. The left side of the fixed rod 42 passes through the left side of the sliding sleeve 41 and is fixedly connected to the left side of the inner wall of the placement box 31. The connecting rod 43 is fixedly connected to the front end of the sliding sleeve 41. The operating mechanism 5 is slidably sleeved on the front end of the connecting rod 43.

[0027] As a technical optimization of this utility model, by setting the connecting mechanism 4, the sliding sleeve 41 can move left and right with the connecting rod 43. The sliding sleeve 41 moves horizontally on the surface of the fixed rod 42, thereby keeping the moving direction of the sliding sleeve 41 stable and avoiding the phenomenon of the sliding sleeve 41 tilting during the movement.

[0028] refer to Figure 4 The operating mechanism 5 includes a cross slide bar 51, a handle 52, and a cross rectangular frame 53. The front end of the connecting rod 43 is slidably sleeved with the cross slide bar 51. The front end of the cross slide bar 51 passes through the front end of the placement box 31 and is fixedly connected with the handle 52. The inner cavity of the placement box 31 is sleeved on the surface of the connecting rod 43 and is horizontally fixedly connected with the cross rectangular frame 53.

[0029] As a technical optimization of this utility model, by setting the operating mechanism 5, the handle 52 can be manually pulled forward. The handle 52 moves forward and drives the cross slide bar 51 to disengage from the cross rectangular frame 53 and contact the limit, so as to realize the control of the movement of the handle 52 and the cross slide bar 51. This avoids the handle 52 and the cross slide bar 51 being unable to move when they are inside the cross rectangular frame 53, which would affect the convenience of mechanical operation.

[0030] refer to Figure 4 Cross grooves 6 are provided on the left and right sides of the surface of the cross rectangular frame 53, corresponding to the positions of the cross slide rod 51. There are several cross grooves 6, which are evenly distributed.

[0031] As a technical optimization of this utility model, the cross groove 6 can assist the cross slide bar 51 in working and also play a limiting role, avoiding the phenomenon that the cross slide bar 51 will get stuck inside the cross groove 6 due to the width of the cross groove 6 being too narrow.

[0032] refer to Figure 3 A groove 7 is provided at the bottom of the rectangular frame 34 and at the position corresponding to the cross plate 33. The groove 7 is used in conjunction with the cross plate 33.

[0033] As a technical optimization of this utility model, the sliding groove 7 can assist the cross plate 33 in working and at the same time play a limiting role, preventing the cross plate 33 from deviating during the movement.

[0034] refer to Figure 3 A rubber pad 8 is fixedly glued to the top of the L-shaped tray 32, and the rubber pad 8 is used in conjunction with the L-shaped tray 32.

[0035] As a technical optimization of this utility model, the rubber pad 8 can assist the L-shaped support plate 32 in its operation and also play a protective role, avoiding the phenomenon of scratches and wear caused by the L-shaped support plate 32 directly contacting the electromagnetic yoke 2.

[0036] The working principle and usage process of this utility model are as follows: When in use, the power supply 1 is turned on, supplying power to the electromagnetic yoke 2. The electromagnetic yoke 2 generates a magnetic field that magnetizes the workpiece. When the workpiece is magnetized, if there are defects on the surface, the increased magnetic resistance at the defect will generate leakage magnetic field, forming a local magnetic field. At this time, magnetic powder is sprinkled on, and the magnetic powder will be attracted and accumulated at the defect, thus revealing the shape and location of the defect, thereby determining its presence. After use, the handle 52 is manually pulled forward. The handle 52 moves forward, causing the cross slide rod 51 to disengage from the cross groove 6. The cross slide rod 51 disengages from the cross rectangular frame 53, releasing its restriction, and the handle 52 moves to the left. The leftward movement of the handle 52 causes the connecting rod 43 and the sliding sleeve 41 to move synchronously, while the sliding sleeve 41 moves stably on the surface of the fixed rod 42. The rear sliding sleeve 41 moves to the left, causing the L-shaped tray 32 and the cross plate 33 to move accordingly. The cross plate 33 moves horizontally inside the rectangular frame 34 through the sliding groove 7. Finally, the L-shaped tray 32 extends to the outside of the placement box 31. Then, the handle 52 is pushed backward, and the handle 52 moves backward, causing the cross slide rod 51 to re-insert into the cross groove 6. The cross slide rod 51 is inside the cross rectangular frame 53 and cannot move, thus achieving a fixing function. The fixing of the cross slide rod 51 keeps the connecting rod 43, the sliding sleeve 41 and the L-shaped tray 32 in a fixed position. At this time, the electromagnetic yoke 2 is placed on the surface of the L-shaped tray 32 for assembly, which makes it convenient for the user to pick up and put down the electromagnetic yoke 2. When the power supply 1 is moved, the electromagnetic yoke 2 is moved synchronously to avoid leaving the electromagnetic yoke 2 on site.

[0037] In summary, this magnetic detection instrument for special equipment works in conjunction with a power supply unit 1, an electromagnetic yoke 2, an auxiliary mechanism 3, a placement box 31, an L-shaped tray 32, a cross plate 33, a rectangular frame 34, and a connecting mechanism 4. When the power supply unit 1 is activated, it supplies power to the electromagnetic yoke 2, generating a magnetic field that magnetizes the workpiece. When the workpiece is magnetized, if there are defects on the surface, the increased magnetic resistance at the defect location will generate leakage magnetic field, forming a local magnetic field. After use, the electromagnetic yoke 2 is placed on the L-shaped tray 32 to combine with the power supply unit 1, facilitating easy access and allowing the power supply unit to be carried simultaneously. This avoids leaving the electromagnetic yoke 2 on-site and solves the problem that existing magnetic detection instruments require tools to generate magnetizing current, and since the tools and power supply are two separate entities, they cannot be combined for transport.
