Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a disassembly tool. Background Art

[0002] In the pipeline magnetic leakage internal detection method, the work requires the pipeline magnetic leakage internal detector to move in the pipeline. The pipeline magnetic leakage internal detector can obtain the corresponding information of the pipeline while moving, and then analyze the metal loss, mileage, hour and hour position and other detection information of the inner and outer walls of the pipeline through data analysis software.

[0003] In the prior art, the pipeline magnetic leakage internal detector mainly includes a probe, a magnetic component (magnetic yoke and permanent magnet, etc.) and a steel brush. The magnetic component is arranged on the two end faces of the probe, and the steel brush is sleeved on the magnetic component. During the detection process of the pipeline magnetic leakage internal detector, a magnetic path is formed between the magnetic component, the steel brush and the pipe wall. The probe obtains the above-mentioned information to be detected by detecting information such as magnetic flux. During the movement of the pipeline magnetic leakage internal detector, the steel brush in flexible contact with the pipeline will rub against the pipe wall and produce wear, and the diameter of the steel brush will become smaller. In order to ensure the detection effect of the pipeline magnetic leakage internal detector, the staff needs to use a screw-type disassembly tool to regularly disassemble and replace the steel brush. During disassembly, the screw-type disassembly tool will fix the steel brush. When the staff operates the screw to rotate to push the magnetic component to move, the steel brush will separate from the magnetic component and then be disassembled.

[0004] However, for pipeline magnetic leakage internal detectors used to detect water drive pipelines, the steel brush must be made of carbon steel, which is very easy to rust. The rusted steel brush will increase its disassembly resistance due to rust adhesion and self-expansion. It is very difficult to rotate the lead screw only by manual thrust, which not only affects the disassembly efficiency of the steel brush, but also increases the labor intensity of the staff.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In order to solve the problem that the disassembly method of the pipeline detection device in the prior art is low in efficiency and will increase the labor intensity of the workers, the present application provides a disassembly tool.

[0034] like Figures 1 to 4As shown, the disassembly tool is used to disassemble the to-be-disassembled part 101 of the detection device 1. The disassembly tool comprises a frame 10, at least two clamping structures 20, a limiting structure 30 and a driving device 40. At least two clamping structures 20 are arranged on the frame 10 and surround to form a clamping space. At least two clamping structures 20 are movably arranged to adjust the size of the clamping space to clamp the to-be-disassembled part 101. The limiting structure 30 is arranged on the frame 10, and at least part of the limiting structure 30 is located on the side of the clamping structure 20 away from the clamping space, so that after the clamping structure 20 clamps the to-be-disassembled part 101, the limiting structure 30 is limited by the clamping structure 20 to limit the movement of the clamping structure 20 away from the to-be-disassembled part 101. The driving device 40 is arranged on the frame 10 and is drivingly connected to the main structure 102 of the detection device 1. The driving device 40 drives the main structure 102 to move away from the to-be-disassembled part 101 to disassemble the to-be-disassembled part 101.

[0035] By applying the technical solution of this embodiment, the disassembly tool is used to disassemble the part to be disassembled 101 of the detection device 1. At least two clamping structures 20 are arranged on the frame 10 of the disassembly tool. The at least two clamping structures 20 are surrounded to form a clamping space and are movably arranged to adjust the size of the clamping space to clamp the part to be disassembled. The limiting structure 30 is arranged on the frame 10, and at least part of the limiting structure 30 is located on the side of the clamping structure 20 away from the clamping space, so that after the clamping structure 20 clamps the part to be disassembled 101, the limiting structure 30 limits the movement of the clamping structure 20 away from the part to be disassembled 101 by limiting the stopper with the clamping structure 20. The driving device 40 is arranged on the frame 10 and is drivingly connected to the main structure 102 of the detection device 1. The driving device 40 drives the main structure 102 to move away from the part to be disassembled 101 to disassemble the part to be disassembled 101. In this way, after the staff assembles the disassembly tool and operates the driving device 40 to start, since the driving device 40 and the clamping structure 20 are both arranged on the frame 10, and the clamping structure 20 can clamp and fix the part to be disassembled 101, the driving device 40 drives the main structure 102 to move away from the part to be disassembled 101, and the main structure 102 can produce relative displacement and separate from the part to be disassembled 101, thereby realizing the automatic disassembly of the part to be disassembled, thereby solving the problem that the disassembly method of the pipeline detection device in the prior art is low in efficiency and will increase the labor intensity of the staff. At the same time, the limiting structure 30 can limit the clamping structure 20 to prevent the clamping structure 20 from shaking or even moving away from the part to be disassembled 101, which makes it unable to stably clamp the part to be disassembled 101, which not only improves the clamping stability of the clamping structure 20, but also improves the operating reliability of the disassembly tool.

[0036] In this embodiment, there are three clamping structures 20 , and the three clamping structures 20 surround and form a clamping space to ensure that the clamping structures 20 have high clamping stability.

[0037] It should be noted that the number of the clamping structures 20 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the clamping structures 20 is two, four, five, six, seven, or more.

[0038] Specifically, since the size of the clamping space can be adjusted, the clamping structure 20 can clamp the to-be-disassembled parts 101 of different specifications and sizes, and the versatility of the disassembly tooling is also improved.

[0039] In this embodiment, the detection device 1 is a pipeline magnetic leakage internal detector.

[0040] In this embodiment, the part to be disassembled 101 is a steel brush of a pipeline magnetic leakage internal detector or a combination of a steel brush and a steel brush tray.

[0041] In this embodiment, the main structure 102 is a probe of the pipeline magnetic leakage internal detector and a magnetic component (magnetic yoke and permanent magnet, etc.) arranged on the probe.

[0042] like Figure 1 As shown, the driving device 40 is a hydraulic cylinder, one of the cylinder body 41 and the piston rod of the hydraulic cylinder is arranged on the frame 10, and the other of the cylinder body 41 and the piston rod is drivingly connected to the main structure 102. In this way, the hydraulic cylinder can provide a more stable and higher upper limit driving force for the disassembly tooling to improve the disassembly reliability of the disassembly tooling. At the same time, the above arrangement makes the arrangement positions of the cylinder body 41 and the piston rod more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0043] Specifically, the hydraulic cylinder is a puller cylinder.

[0044] In this embodiment, the cylinder body 41 is disposed on the frame body 10 , and the piston rod is drivingly connected to the main structure 102 .

[0045] In other embodiments not shown in the drawings, the piston rod is arranged on the frame, and the cylinder is drivingly connected to the main structure.

[0046] Optionally, the frame 10 has a first matching portion 11, and the clamping structure 20 has a second matching portion 21, one of the first matching portion 11 and the second matching portion 21 is a protrusion, and the other of the first matching portion 11 and the second matching portion 21 is a recess, and the protrusion extends into the recess and is slidably arranged along the extension direction of the recess. In this way, the above arrangement, on the one hand, realizes the sliding connection between the clamping structure 20 and the frame 10 through the sliding cooperation between the first matching portion 11 and the second matching portion 21; on the other hand, it makes the structure of the first matching portion 11 and the second matching portion 21 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0047] like Figure 1 and Figure 2 As shown, the clamping structure 20 includes a main body 22 and a hook portion 23, the main body 22 has a second matching portion 21, and at least two main bodies 22 surround to form a clamping space. The hook portion 23 is arranged on the main body 22, and at least part of the hook portion 23 is located in the clamping space. In the process of the driving device 40 driving the main structure 102 to move away from the part to be disassembled 101, the hook portion 23 is hooked and matched with the part to be disassembled 101. In this way, the above arrangement, on the one hand, forms a clamping space around the main body 22, that is, the part to be disassembled 101 is clamped and fixed by the main body 22; on the other hand, the hook-shaped portion 23 and the part to be disassembled 101 can prevent the part to be disassembled 101 from falling out of the clamping space through the hook-shaped portion 23 and the part to be disassembled 101, thereby improving the disassembly reliability of the disassembly tooling.

[0048] In this embodiment, the upper surface of the hook portion 23 is a plane.

[0049] Specifically, the detection device 1 is usually placed vertically on the work surface during the disassembly process, and the steel brush is a cylindrical structure. The hook-shaped portion 23 with a flat upper surface can be stably hung with the lower surface of the steel brush, which not only increases the hanging area between the two and improves the hanging reliability between the hook-shaped portion 23 and the steel brush, but also ensures that the upper surfaces of each hook-shaped portion 23 are on the same horizontal plane, thereby ensuring that the steel brush will not tilt or deflect during the disassembly process, further improving the disassembly reliability of the disassembly tooling.

[0050] like Figure 1 and Figure 2As shown, the second matching portion 21 is a protrusion, the first matching portion 11 is a recess, the recess is a strip hole, the main body 22 is rod-shaped and includes a first sub-rod segment 221 and a second sub-rod segment 222 connected to each other, one end of the second sub-rod segment 222 close to the first sub-rod segment 221 extends into the strip hole to form the second matching portion 21, one end of the first sub-rod segment 221 away from the second sub-rod segment 222 is located outside the strip hole, and the hook portion 23 is arranged on the second sub-rod segment 222. The disassembly tool also includes a first fastener 50, which is sleeved on the first sub-rod segment 221 and threadedly matched therewith. In the process of rotating the first fastener 50, the first fastener 50 abuts against at least part of the outer surface of the frame 10 to fix the clamping structure 20. In this way, on the one hand, the above-mentioned arrangement makes the structure of the main body 22 and the formation method of the second matching part 21 simpler, easier to process and realize, thereby reducing the processing cost of the clamping structure 20 and the processing difficulty of the staff; on the other hand, the first fastener 50 can fix the clamping structure 20 through its cooperation with the first sub-rod segment 221, that is, the frame 10, so as to prevent the clamping structure 20 from sliding and causing the clamping structure 20 to separate from the part to be disassembled 101 after the staff adjusts the position of the clamping structure 20, thereby improving the disassembly stability of the disassembly tooling.

[0051] Specifically, the first fastener 50 is a nut. When the staff rotates the nut, due to the threaded cooperation between the nut and the first sub-rod segment 221, the nut can drive the hook portion 23 set on the second sub-rod segment 222 to move. When the hook portion 23 is stably hooked with the lower surface of the steel brush and the nut is tightly abutted against the frame 10, the clamping structure 20 can be fixed by the friction between the nut and the frame 10 and the friction between the hook portion 23 and the steel brush.

[0052] Specifically, after the first fastener 50 fixes the clamping structure 20, the rod-shaped main body 22 can be vertically arranged like the vertically placed detection device 1, thereby increasing the matching area between the main body 22 and the steel brush while ensuring that the upper surface of the hook-shaped portion 23 and the lower surface of the steel brush are also horizontal planes, so as to improve the matching stability between the two and avoid deflection of the steel brush.

[0053] In this embodiment, the main body 22 is a cylindrical rod.

[0054] Specifically, a mating plane is processed on the outer peripheral surface of the end of the main body 22 forming the second mating portion 21. The mating plane ensures that the end of the main body 22 can extend into the strip hole while increasing the mating area between the two, thereby improving the sliding stability of the clamping structure 20.

[0055] Specifically, by cooperating with the matching plane and the inner wall of the strip hole, the main body 22 can also be prevented from rotating, so as to prevent the main body 22 from rotating with the first fastener 50 during the process of the staff rotating the first fastener 50, thereby preventing the first fastener 50 from being able to be fastened.

[0056] It should be noted that the structure of the main body 22 is not limited thereto, and if it is set as a square rod, the above-mentioned effect can also be achieved.

[0057] like Figure 1 As shown, the frame 10 includes a cylindrical structure 12 and a rod-shaped structure 13. The cylindrical structure 12 is sleeved on the cylinder 41 of the driving device 40 and is coaxially arranged with the cylinder 41. The rod-shaped structure 13 is arranged on the cylindrical structure 12 and has a first matching portion 11. There are at least two rod-shaped structures 13, and at least two rod-shaped structures 13 are arranged at intervals around the central axis of the cylindrical structure 12. At least two clamping structures 20 are arranged one-to-one corresponding to the at least two rod-shaped structures 13. The cylindrical structure 12 and the cylinder 41 are threadedly matched to adjust the position of the cylindrical structure 12 on the cylinder 41 when the cylindrical structure 12 is rotated. In this way, the above-mentioned arrangement realizes the connection between the frame 10 and the cylinder body 41 through the cylindrical structure 12, and at the same time, the staff can adjust the position of the frame 10 on the cylinder body 41 by rotating the cylindrical structure 12, thereby adjusting the position of the clamping structure 20 set on the frame 10, and then adjusting the clamping position of the clamping structure 20 on the disassembled part 101, thereby improving the clamping stability of the clamping structure 20.

[0058] In this embodiment, the extending direction of the strip-shaped holes is consistent with the extending direction of the rod-shaped structure 13 .

[0059] Specifically, since each rod-like structure 13 is arranged around the central axis of the cylindrical structure 12, and the extension direction of the strip hole is consistent with the extension direction of the rod-like structure 13, the three clamping structures 20 arranged in the strip holes have high coaxiality, so as to further improve the clamping stability of the clamping structure 20 on the steel brush.

[0060] It should be noted that the number of rod-shaped structures 13 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of rod-shaped structures 13 is two, four, five, six, seven, or more.

[0061] In this embodiment, the thread provided on the cylinder body 41 is a trapezoidal thread, so as to improve the load bearing capacity of the thread structure in the vertical direction, thereby extending the service life of the disassembly tool.

[0062] like Figure 1As shown, the limiting structure 30 includes a connecting portion 31 and a limiting portion 32. The limiting portion 32 is connected to the frame 10 through the connecting portion 31. The limiting portion 32 is located on the side of the clamping structure 20 away from the clamping space and has a limiting surface 321. When the limiting structure 30 and the clamping structure 20 are in a position-limiting stop, the limiting surface 321 abuts against at least part of the outer surface of the clamping structure 20. In this way, while the above arrangement realizes the connection between the limiting portion 32 and the frame 10 through the connecting portion 31, the setting position of the limiting portion 32 is more reasonable to ensure that the limiting portion 32 can be in a position-limiting stop with the clamping structure 20.

[0063] like Figure 1 As shown, the connection part 31 includes a first connection member 311 and a second connection member 312, and the first connection member 311 is arranged on the frame 10 and has a first penetration hole 3111. At least part of the second connection member 312 is penetrated in the first penetration hole 3111. Among them, the limiting part 32 is arranged on one end of the second connection member 312 close to the clamping structure 20, and the second connection member 312 is threadedly matched with the first connection member 311, so that when the second connection member 312 is rotated, the limiting part 32 is driven to move by the second connection member 312. In this way, the staff can adjust the position of the limiting part 32 by rotating the second connection member 312, thereby ensuring that the limiting part 32 can be limited and stopped with the clamping structure 20 when the clamping structure 20 clamps the to-be-disassembled parts 101 of different specifications and sizes, thereby improving the reliability of the limit stop of the limiting structure 30.

[0064] In this embodiment, the second connecting member 312 is a bolt.

[0065] In this embodiment, there are three limiting structures 30 , and the three limiting structures 30 are arranged in a one-to-one correspondence with the three rod-shaped structures 13 .

[0066] like Figure 1 and Figure 2As shown, the limiting part 32 includes a cylindrical connecting part 322, a plate-shaped limiting body 323 and a second fastener 324. The cylindrical connecting part 322 has a second through hole connected to its inner hole, and one end of the second connecting part 312 away from the first connecting part 311 extends into the inner hole of the cylindrical connecting part 322. The plate-shaped limiting body 323 is arranged on one end of the cylindrical connecting part 322 away from the second connecting part 312, and the plate surface of the plate-shaped limiting body 323 facing the clamping structure 20 is the limiting surface 321. At least part of the second fastener 324 is penetrated in the second through hole. Among them, the second fastener 324 is threadedly matched with the hole wall of the second through hole. In the process of rotating the second fastener 324, the second fastener 324 abuts against the second connecting part 312 to fix the second connecting part 312; and / or, the plate-shaped limiting body 323 is an arc-shaped plate. In this way, the above arrangement, on the one hand, fixes the second connecting member 312 through the abutment between the second fastener 324 and the second connecting member 312, thereby fixing the limiting portion 32; on the other hand, the structure of the limiting portion 32 is simpler, easy to process and realize, thereby reducing the processing difficulty of the staff. At the same time, the plate surface of the plate-shaped limiting body 323, which is a curved plate, is a curved surface, that is, the limiting surface 321 is a curved surface, so that the shape of the limiting surface 321 can match the outer peripheral surface of the main body 22, thereby increasing the matching area between the limiting portion 32 and the main body 22 and improving the reliability of the limiting stop of the limiting portion 32.

[0067] In this embodiment, the second fastener 324 is a bolt or a screw.

[0068] It should be noted that the structure of the plate-shaped limiting body 323 is not limited thereto and can be adjusted according to working conditions and usage requirements. If the main body 22 is a square rod, the plate-shaped limiting body 323 is also formed by connecting a plurality of plate-shaped structures in sequence to ensure that the shape of the limiting surface 321 can match the shape of the outer peripheral surface of the main body 22.

[0069] like Figure 1 , Figure 3 and Figure 4 As shown, the disassembly tool also includes a connection structure 60, through which the piston rod is driven and connected to the main structure 102, and the connection structure 60 includes a mounting portion 61, a columnar connection portion 62 and a cylindrical matching portion 63, wherein the columnar connection portion 62 is arranged on the mounting portion 61, and the columnar connection portion 62 extends into the connecting end of the main structure 102 to connect with the connecting end. The cylindrical matching portion 63 is arranged on the mounting portion 61, and the piston rod extends into the inner hole of the cylindrical matching portion 63 and is connected with the cylindrical matching portion 63. Among them, the columnar connection portion 62 and the cylindrical matching portion 63 are respectively located on both sides of the mounting portion 61. In this way, by connecting the piston rod and the main structure 102 through the specially designed connection structure 60, the connection reliability between the piston rod and the main structure 102 can be improved, thereby improving the operating reliability of the disassembly tool.

[0070] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0071] The disassembly tool is used to disassemble the parts to be disassembled of the detection device. At least two clamping structures are arranged on the frame of the disassembly tool. The at least two clamping structures are surrounded to form a clamping space and are movably arranged to adjust the size of the clamping space to clamp the parts to be disassembled. The limiting structure is arranged on the frame, and at least part of the limiting structure is located on the side of the clamping structure away from the clamping space, so that after the clamping structure clamps the parts to be disassembled, the limiting structure limits the movement of the clamping structure away from the parts to be disassembled by limiting the stopper with the clamping structure. The driving device is arranged on the frame and is drivingly connected to the main structure of the detection device. The driving device drives the main structure to move away from the parts to be disassembled to disassemble the parts to be disassembled. In this way, after the staff assembles the disassembly tool and operates the driving device to start, since the driving device and the clamping structure are both arranged on the frame, and the clamping structure can clamp and fix the part to be disassembled, the main structure can generate relative displacement and separate from the part to be disassembled during the process of the driving device driving the main structure to move away from the part to be disassembled, thereby realizing the automatic disassembly of the part to be disassembled, thereby solving the problem that the disassembly method of the pipeline detection device in the prior art is inefficient and will increase the labor intensity of the staff. At the same time, the limiting structure can limit the clamping structure to prevent the clamping structure from shaking or even moving away from the part to be disassembled, which will cause it to be unable to stably clamp the part to be disassembled, which not only improves the clamping stability of the clamping structure, but also improves the operational reliability of the disassembly tool.
