Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to a pipeline damage detection device. Background Art

[0002] Ultrasonic flaw detection is a method of checking part defects. It generally refers to ultrasonic testing, which is a conventional non-destructive testing method. Non-destructive testing is a means of checking the surface and internal quality of the inspected parts without damaging the workpiece or the working state of the raw materials. During the inspection, ultrasonic flaw detectors are mostly used for inspection.

[0003] When inspecting smaller and lighter pipes, for the sake of ease of inspection, they are usually inspected using a portable ultrasonic detector, which is transported to the pipe stacking area before the pipes are inspected. When in use, the operator moves a handheld inspection head over the pipe surface for inspection. During the inspection, the pipe needs to be rotated for coordination. However, the handheld inspection head is inevitably subject to shaking and swaying during use, which may cause the inspected area to be inspected again, resulting in incomplete inspection of the pipe surface.

[0004] Therefore, the present invention proposes a pipeline damage detection device to solve this problem. Summary of the invention

[0005] The purpose of this application is to solve the problems in the above-mentioned background technology, and provide a pipeline damage detection device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] The pipeline damage detection device comprises a detector on which an ultrasonic probe is installed through a wire, and also comprises:

[0008] A mounting plate, which is used to carry the detector, a clamping bracket is slidably mounted on the mounting plate, the clamping bracket is used to clamp the ultrasonic probe, a fixed plate is mounted on the mounting plate, a rotating plate is rotatably mounted on the fixed plate, a resistance plate is slidably mounted on the mounting plate, a rotating plate is also rotatably mounted on the resistance plate, the resistance plate and the fixed plate are used to clamp the pipeline, a handle is eccentrically mounted on the rotating plate, the mounting plate includes an intermediate plate, side plates are hinged on both sides of the intermediate plate, the resistance plate and the fixed plate are mounted on the intermediate plate, and the detector is detachably mounted on one of the side plates;

[0009] The resistance member is installed on the mounting plate. The resistance member comprises a mounting block installed on the mounting plate. A threaded rod is threadedly connected to the mounting block. The free end of the threaded rod is used to resist the resistance plate.

[0010] Further, a receiving groove for receiving a detector is formed in the mounting plate. A sliding groove is formed in the mounting plate. A connecting plate is slidably mounted in the sliding groove. A U-shaped plate is hinged to the connecting plate. A through hole for a wire to pass through is formed in the U-shaped plate. When the connecting plate slides into the sliding groove, the rotation of the U-shaped plate on the connecting plate is restricted.

[0011] Further, a wide groove for slidably cooperating with the抵触板 (it seems there is a typo here, assuming it should be a correct part name) is formed in the mounting plate. The mounting block is movably inserted into the wide groove. A contact block rotatably connected to the threaded rod is mounted on the mounting block. A guide rod slidably cooperating with the mounting block is mounted on the contact block.

[0012] Further, the receiving groove is formed in one of the side plates. The sliding groove penetrates the side plate. A support rod is hinged to the connecting plate. A connecting rod is mounted on the mounting block. A jack is formed in the side plate. A plug rod for inserting into the jack is mounted on the connecting rod. A short rod is mounted on the contact block. A short hole for receiving the short rod is formed in the support rod. A handle plate is mounted on the other side plate.

[0013] Further, a long groove for slidably cooperating with the clamping bracket is formed in the mounting plate. A plurality of elastic plates are mounted in the long groove. The distance between adjacent elastic plates is equal to the width of the ultrasonic probe.

[0014] Further, a limiting plate is mounted on the connecting rod. A hinged plate is hinged to the limiting plate. A limiting hole is formed in the handle plate. A limiting rod for inserting into the limiting hole is slidably mounted on the hinged plate. A plurality of protrusions are provided in the limiting hole. A plurality of grooves for receiving the protrusions are formed on the limiting rod.

[0015] Further, a receiving hole for receiving the limiting plate and the hinged plate is formed in the side plate.

[0016] Further, a shielding plate is mounted on the contact block. The projection of the shielding plate on the surface of the mounting block coincides with the projections of the threaded rod and the guide rod on the surface of the mounting block.

[0017] Further, a positioning rod is mounted in the wide groove. A positioning hole for receiving the positioning rod is formed in the mounting block.

[0018] Further, an insertion block is mounted on the rotating plate. The insertion block is used to contact the inner cavity of the pipeline.

[0019] The beneficial effects of this application are as follows:

[0020] When this application is in use, place the detector on the mounting plate and place the ultrasonic probe on the clamping bracket. During use, rotate the threaded rod to抵触 the抵触 plate, so that the抵触 plate and the fixing plate clamp the pipeline through the rotating plate. At this time, rotating the rotating plate can make the pipeline rotate while being clamped. The ultrasonic probe is clamped and fixed by the clamping bracket, reducing the possibility of the ultrasonic probe shaking during use, thereby increasing the stability of the device during use. After use, rotate the side plate to reduce the area occupied by the entire mounting plate, facilitating the carrying of the device.

[0021] When this application is in use, first slide the connecting plate upward so that the hinge point of the connecting plate and the U-shaped plate is outside the sliding groove. Rotate the U-shaped plate to make it away from the receiving groove. After placing the detector in the receiving groove, then rotate the U-shaped plate to the position where the inner wall of the U-shaped plate contacts the detector. A guiding through hole is provided on the U-shaped plate. At this time, the hole presses on the wire. Then slide the connecting plate downward. When its hinge point with the U-shaped plate moves into the sliding groove, the rotation of the U-shaped plate is restricted, further increasing the stability of the detector during use.

[0022] When this application is in use, the mounting block is inserted into the wide groove, and the contact block faces the side of the抵触 plate. At this time, rotate the threaded rod to drive the contact block to gradually approach the抵触 plate and抵触 the抵触 plate. During the process, the axis of the guiding rod and the threaded rod are not collinear. The sliding of the guiding rod on the mounting block restricts the contact block so that it can only slide and cannot rotate with the threaded rod, increasing the feasibility of the device. All components of the抵触 member are installed on the mounting block, and the mounting block is detachably connected to the mounting plate. During use, when the threaded rod is worn out after long-term use, it is convenient to replace the抵触 member, increasing the practicality of the device.

[0023] When this application needs to be stored, remove the mounting block from the wide groove. After removal, rotate the side plate to the vertical direction. When the support rod is rotated to the above position, then insert the connecting rod into the jack through the insertion rod so that the contact block is connected to the side plate. During the process, insert the short rod into the short hole so that the support rod, mounting block, contact block and connecting rod form a structure similar to a U-shaped handle, and the handle plate is also U-shaped. When the device is stored, the handle structure formed by the handle plate or the support rod, mounting block, contact block and connecting rod provides a grasping point for the operator, further facilitating the transportation of the device.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Example

[0037] like Figure 1 - Fig.11As shown in the figure, the pipeline damage detection device proposed in the first embodiment of the present application includes a detector 1, on which an ultrasonic probe 101 is installed through a wire. The detector 1 is an existing ultrasonic detector, which is attached to the outer wall of the pipeline through the ultrasonic probe 101. After releasing ultrasonic waves to the pipeline through the ultrasonic probe 101, the ultrasonic waves are received, and then the pipeline is detected. It also includes:

[0038] A mounting plate 2, which is used to carry the detector 1. A clamping bracket 201 is slidably mounted on the mounting plate 2. The clamping bracket 201 is used to clamp the ultrasonic probe 101. During use, the detector 1 is placed on the mounting plate 2, and then the ultrasonic probe 101 is placed on the clamping bracket 201. The clamping bracket 201 includes a rod body and a plate body. The plate body is in a U shape, and the distance between the two parallel sides of the plate body is less than the width of the ultrasonic probe 101. When connecting it to the ultrasonic probe 101, the plate body is掰动 (it should be "bent" in English), so that the mutually parallel side walls are separated from each other. After the ultrasonic probe 101 is placed on the plate body, the ultrasonic probe 101 is clamped and fixed by the plate body, which increases the stability of the ultrasonic probe 101 during use;

[0039] A fixing plate 202 is installed on the mounting plate 2. A rotating plate 203 is rotatably mounted on the fixing plate 202. A抵触板 (it should be "contact plate" in English) 204 is slidably mounted on the mounting plate 2, and a rotating plate 203 is also rotatably mounted on the contact plate 204. The contact plate 204 and the fixing plate 202 are used to clamp the pipeline. A grip 205 is eccentrically installed on the rotating plate 203. During use, the pipeline is placed between the fixing plate 202 and the contact plate 204, and then the contact plate 204 is slid, so that the contact plate 204 and the fixing plate 202抵触 (it should be "contact" in English) the two ends of the pipeline, and the two of them contact the pipeline through the rotating plate 203, restricting the movement of the pipeline along its own axis direction. And the rotating plate 203 is rotationally matched with the contact plate 204 or the fixing plate 202, so that the pipeline can rotate with the rotating plate 203. During use, by rotating the grip 205, the rotating plate 203 rotates, thereby driving the pipeline to rotate, so that the surface of the pipeline can smoothly contact the ultrasonic probe 101. When this part of the detection is completed, the clamping bracket 201 is slid, so that the ultrasonic probe 101 slides along the length direction of the pipeline, so that the ultrasonic probe 101 can contact the pipeline more comprehensively, improving the detection effect of the device;

[0040] The mounting plate 2 includes an intermediate plate 206, and side plates 207 are hinged on both sides of the intermediate plate 206. The contact plate 204 and the fixing plate 202 are installed on the intermediate plate 206, and the detector 1 is detachably installed on one of the side plates 207. When the device needs to be carried, the side plate 207 is rotated to a direction perpendicular to the intermediate plate 206, reducing the floor area of the entire device and facilitating its handling;

[0041] The resistance member 3 is installed on the mounting plate 2. The resistance member 3 includes a mounting block 301 installed on the mounting plate 2. The mounting block 301 is threadedly connected with a threaded rod 302. The free end of the threaded rod 302 is used to resist the resistance plate 204. When the pipeline is placed between the fixed plate 202 and the resistance plate 204, the threaded rod 302 is rotated to make the free end of the threaded rod 302 resist the resistance plate 204, so that the resistance plate 204 can resist the pipeline, and then the resistance plate 204 and the fixed plate 202 clamp and fix the pipeline, thereby improving the stability of the pipeline when in use. When the pipeline inspection is completed, the threaded rod 302 is reversed to release the resistance to the resistance plate 204, and then the resistance plate 204 is slid to release the fixation of the pipeline;

[0042] Compared with the prior art, when in use, the detector 1 is placed on the mounting plate 2, and the ultrasonic probe 101 is placed on the clamping bracket 201. When in use, the threaded rod 302 is rotated to make it contact with the contact plate 204, so that the contact plate 204 and the fixing plate 202 clamp the pipeline through the rotating plate 203. At this time, rotating the rotating plate 203 can make the pipeline rotate while being clamped. The ultrasonic probe 101 is clamped and fixed by the clamping bracket 201, which reduces the possibility of shaking of the ultrasonic probe 101 during use, thereby increasing the stability of the device during use. After use, the side plate 207 is rotated to reduce the area occupied by the entire mounting plate 2, making it easier to carry the device. Example

[0043] like Figure 3 , Figure 6 and Figure 8 As shown, the second embodiment further discloses the mounting plate 2 and the abutment member 3 on the basis of the first embodiment. In the second embodiment, a receiving groove 4 for receiving the detector 1 is provided on the mounting plate 2. The depth of the receiving groove 4 is less than the thickness of the detector 1. In this embodiment, the receiving groove 4 is provided on the side plate 207. When the device is used, the detector 1 is placed in the receiving groove 4, and the position of the detector 1 on the mounting plate 2 is fixed, thereby increasing the stability of the detector 1 when in use.

[0044] The mounting plate 2 is provided with a sliding groove 5, in which a connecting plate 6 is slidably installed, and a shaped plate 7 is hingedly connected to the connecting plate 6, and a through hole 8 for the wire to pass through is provided on the shaped plate 7. When the connecting plate 6 slides into the sliding groove 5, the rotation of the shaped plate 7 on the connecting plate 6 is restricted, so that the connecting plate 6 can be rotated freely. Figure 1From the main perspective, when in use, first slide the connecting plate 6 upwards so that the hinge point between the connecting plate 6 and the shaped plate 7 is located outside the sliding groove 5, rotate the shaped plate 7 to move it away from the accommodating groove 4, place the detector 1 into the accommodating groove 4, and then rotate the shaped plate 7 to rotate it to the position where the inner wall of the shaped plate 7 contacts the detector 1. At this time, the inner wall of the through hole 8 is pressed on the wire, and then slide the connecting plate 6 downwards so that the hinge point between it and the shaped plate 7 moves into the sliding groove 5. The rotation of the shaped plate 7 is restricted, which further increases the stability of the detector 1 when in use.

[0045] like Figure 3 and Figure 5 As shown, in the second embodiment, a wide groove 9 is provided on the mounting plate 2 to slide with the abutment plate 204, a mounting block 301 is movably inserted in the wide groove 9, the wide groove 9 is provided on the middle plate 206, a contact block 303 rotatably connected to the threaded rod 302 is installed on the mounting block 301, and a guide rod 304 slidably matched with the mounting block 301 is installed on the contact block 303. When in use, the mounting block 301 is inserted into the wide groove 9, and the contact block 303 faces one side of the abutment plate 204. At this time, the threaded rod 302 is rotated to drive the contact block 303 to gradually approach the abutment plate 204 and When the contact plate 204 contacts with each other, the axes of the guide rod 304 and the threaded rod 302 are not colinear. The guide rod 304 slides on the mounting block 301 to restrict the contact block 303, so that it can only slide and cannot rotate with the threaded rod 302, thereby increasing the feasibility of the device. All parts of the contact member 3 are mounted on the mounting block 301, and the mounting block 301 is detachably connected to the mounting plate 2. When the device is in use, when the threaded rod 302 is worn out due to long-term use, it is convenient to replace the contact member 3, thereby increasing the practicality of the device.

[0046] like Figure 2 , Figure 6 and Figure 7As shown, in the second embodiment, the receiving groove 4 is opened on one of the side plates 207. The sliding groove 5 penetrates through the side plate 207. A support rod 10 is hinged on the connecting plate 6. The depth of the sliding groove 5 is such that when the U-shaped plate 7 slides to contact the detector 1, the hinge point of the U-shaped plate 7 and the connecting plate 6 is located within the sliding groove 5, and the support rod 10 is also located within the sliding groove 5. At this time, since the mounting plate 2 is placed on the ground or the workbench, the side away from the sliding groove 5 of the support rod 10 forms the bottom surface of the side plate 207. However, at this time, the U-shaped plate 7 still does not fit the upper surface of the side plate 207, that is, the connecting plate 6 can still slide a certain distance within the sliding groove 5. During use, when the hinge point between the U-shaped plate 7 and the connecting plate 6 is located outside the sliding groove 5, the support rod 10 is located within the sliding groove 5. After restricting the movement of the detector 1 on the mounting plate 2 through the U-shaped plate 7, rotate the side plate 207 to make it rotate to the vertical direction, and continue to push the connecting plate 6 into the sliding groove 5, so that the connecting plate 6 is further inserted into the sliding groove 5, thereby enabling the support rod 10 to move outside the side plate 207. Then rotate the support rod 10 so that the height of the free end of the support rod 10 is higher than the upper surface of the side plate 207;

[0047] A connecting rod 11 is installed on the mounting block 301. A jack 12 is opened on the side plate 207. An insertion rod 13 for inserting into the jack 12 is installed on the connecting rod 11. A short rod 15 is installed on the contact block 303. A short hole 16 for accommodating the short rod 15 is opened on the support rod 10. A handle plate 14 is installed on the other side plate 207. When storage is required, remove the mounting block 301 from the wide groove 9. After removal, rotate the side plate 207 to the vertical direction. When the support rod 10 is rotated to the above position, then insert the connecting rod 11 into the jack 12 through the insertion rod 13, so that the contact block 303 is connected to the side plate 207. During the process, the short rod 15 is also inserted into the short hole 16, so that the contact block 303 is connected to the support rod 10, thereby enabling the support rod 10, the mounting block 301, the contact block 303 and the connecting rod 11 to form a structure similar to a U-shaped handle, and the handle plate 14 is also U-shaped. When the device is stored, the handle structure formed by the handle plate 14 or the support rod 10, the mounting block 301, the contact block 303 and the connecting rod 11 provides a grasping point for the operator, further facilitating the transportation of the device;

[0048] During the process, the抵触 member 3 not only functions to抵触 the抵触 plate 204, but also can cooperate with the support rod 10 to form a handle structure, increasing the practicality of the抵触 member 3.

[0049] Such as Fig. 9 It should be noted that there is an unclear "抵触" in the original text which may need to be further clarified to ensure more accurate translation. Here it is tentatively translated as "抵触".As shown, in the second embodiment, a long groove 17 is provided on the mounting plate 2 to slide with the clamping bracket 201, and a plurality of elastic plates 18 are installed in the long groove 17. The distance between adjacent elastic plates 18 is equal to the width of the ultrasonic probe 101. The bottom of the rod body of the clamping bracket 201 is installed with a plate body slidably installed in the long groove 17. When the clamping bracket 201 slides, the plate body at the bottom of the clamping bracket 201 resists the elastic plate 18, causing it to undergo elastic deformation so that the clamping bracket 201 can pass. When the device is detected, the rotating shaft is rotated. When the plate 203 is moved, the clamping bracket 201 is limited by the elastic plate 18, which increases the stability of the clamping bracket 201 during use, and further increases the detection accuracy of the device. After a part of the pipeline is detected, the clamping bracket 201 is slid to move to the next part, and the interval of the elastic plate 18 is consistent with the width of the ultrasonic probe 101. Then, when the ultrasonic probe 101 detects the pipeline, the head end of this detection section is the tail end of the previous detection section, which can more comprehensively inspect the pipeline and improve the detection effect of the device. Example

[0050] like Figure 1 - Fig.11 As shown, the third embodiment further discloses the present application based on the second embodiment.

[0051] In the third embodiment, a limiting plate 19 is installed on the connecting rod 11, and a hinge plate 20 is hinged on the limiting plate 19. A limiting hole 21 is provided on the handle plate 14, and a limiting rod 23 for inserting into the limiting hole 21 is slidably installed on the hinge plate 20. A plurality of protrusions 24 are provided in the limiting hole 21, and a plurality of grooves 29 for accommodating the protrusions 24 are provided on the limiting rod 23. When storage is required, the two side plates 207 are rotated to a position parallel to each other. At this time, the hinge plate 20 is rotated, The hinge plate 20 is brought close to the handle plate 14. When the hinge plate 20 is fitted with the side wall of the handle plate 14, the limiting rod 23 is slid to be inserted into the limiting hole 21. At this time, the rotation of the hinge plate 20 is restricted, and the total length of the hinge plate 20 and the limiting plate 19 remains unchanged, thereby restricting the tendency of the insertion rod 13 to be away from the insertion hole 12, thereby increasing the stability of the connection between the mounting block 301 and the side plate 207, thereby reducing the possibility of the abutment member 3 and the side plate 207 being separated when the device is carried, thereby increasing the practicality of the device;

[0052] When the limiting rod 23 is inserted into the limiting hole 21, the protrusion 24 is inserted into the groove 29, which increases the contact area between the limiting rod 23 and the limiting hole 21, thereby increasing the connection strength between the two and increasing the stability of the device during use. When disassembly is required, the limiting rod 23 can be pulled out of the limiting hole 21 to restore the rotation of the hinge plate 20 and release the connection between the handle plate 14 and the mounting block 301.

[0053] In Embodiment 3, a receiving hole 22 for receiving the limiting plate 19 and the hinge plate 20 is formed in the side plate 207. The free end of the limiting plate 19 is in a U shape and is sleeved outside the connecting rod 11, enabling it to be detachably connected to the connecting rod 11. Since the handle formed by the抵触 member 3 and the support rod 10 is necessarily located at the receiving groove 4, that is, the placement position of the detector 1. When the device is in use, the limiting plate 19 is detached from the connecting rod 11 and then placed into the receiving hole 22, reducing the possibility that the limiting plate 19 blocks the operator's line of sight when the device detects the pipeline and increasing the practicability of the device.

[0054] In Embodiment 3, a shielding plate 25 is installed on the contact block 303. The projection of the shielding plate 25 on the surface of the mounting block 301 coincides with the projections of the threaded rod 302 and the guide rod 304 on the surface of the mounting block 301. When the mounting block 301 forms a handle structure, the shielding plate 25 is located on the upper and lower surfaces of the mounting block 301, so that when the operator holds it by hand, the operator will not directly contact the threaded rod 302 or the guide rod 304, increasing the contact area between the operator's hand and the handle structure, thereby reducing the pressure generated by the device on the operator's hand when the device is carried and increasing the comfort of the operator when carrying.

[0055] In Embodiment 3, a positioning rod 26 is installed in the wide groove 9, and a positioning hole 27 for receiving the positioning rod 26 is formed in the mounting block 301. When the device is in use and the抵触 member 3 needs to be installed, the positioning hole 27 on the mounting block 301 is aligned with the positioning rod 26, and then the mounting block 301 is inserted into the wide groove 9, so that when the mounting block 301 is inserted into the wide groove 9, the sliding of the mounting block 301 in the wide groove 9 is restricted. During use, the stability of the mounting block 301 during use is increased, and it is also convenient to install the mounting block 301, increasing the practicability of the device.

[0056] In Embodiment 3, a plug block 28 is installed on the rotating plate 203, and the plug block 28 is used to contact the inner cavity of the pipeline. When the pipeline is installed, the inner cavity of the pipeline is first sleeved on the plug block 28 located on the fixing plate 202, and then the contact plate 204 is slid to complete the connection, so that the plug block 28 can maintain a certain height even when not clamped. The plug block 28 plays a role in lifting one end of the pipeline, increasing the convenience of the device when installing the pipeline.

[0057] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
