Description

Technical Field

[0001] The present application relates to the field of hardness detection, and in particular to a multi-point hardness detection device for special equipment. Background Art

[0002] As one of the special equipment, the pressure pipeline has characteristics such as flammable and explosive conveying media. To ensure the safety and reliability of the pressure pipeline during use, regular inspections are required.

[0003] One of the inspection contents of the pressure pipeline includes hardness detection of the pressure pipeline. Specifically, hardness data at multiple locations within a specific area of the pressure pipeline are obtained through a hardness tester, so as to judge whether the overall strength, wear resistance, and fatigue resistance of the pressure pipeline meet the requirements.

[0004] Currently, the operation process of obtaining the hardness data of the pressure pipeline through a hardness tester is mainly completed manually. Specifically, after the operator arrives at the area to be detected of the pressure pipeline, the detection probe of the hardness tester is contacted with the outer wall of the pressure pipeline multiple times along the circumferential direction of the pressure pipeline to obtain the corresponding hardness data of the pressure pipeline.

[0005] In view of the above related technologies, in the actual operation process of the above detection method, to improve the detection accuracy, it is necessary for the operator to frequently move the detection probe of the hardness tester to contact different positions on the circumference of the pressure pipeline. On the one hand, the overall operation efficiency is low. On the other hand, during the detection process, for some pressure pipelines with a relatively high position, the operator needs to use auxiliary tools to complete the detection operation, and the overall operation is relatively inconvenient. Therefore, there is room for improvement. Summary of the Invention

[0006] In order to improve the overall operation efficiency of the hardness detection of the pressure pipeline, the present application provides a multi-point hardness detection device for special equipment.

[0007] The multi-point hardness detection device for special equipment provided by the present application adopts the following technical solutions:

[0008] A multi-point hardness detection device for special equipment includes a support frame body, a detection mechanism, and a driving mechanism;

[0009] The detection mechanism is arranged on the support frame body. The detection mechanism includes a base, a first sliding driving member, and a hardness tester. The hardness tester includes a detection probe. The detection probe is connected to the base and the detection probe is perpendicular to the plane where the support frame body is located. The first sliding driving member is drivingly connected to the base and is used to drive the base to slide in a direction perpendicular to the plane where the support frame body is located;

[0010] The driving mechanism is arranged on the support frame body. The driving mechanism includes a driving bracket, and the driving bracket is provided with a pipe-holding assembly and a driving assembly. The pipe-holding assembly is used for holding the pressure pipeline; the driving assembly is used to cooperate with the pipe-holding assembly to drive the support frame body to move circumferentially around the pressure pipeline.

[0011] By adopting the above technical solution, when detecting the hardness of the pressure pipeline, the support frame body is placed on the pipeline. After the pressure pipeline is held by the pipe-holding assembly at the driving mechanism, the driving assembly cooperates with the pipe-holding assembly to drive the support frame body to drive the detection mechanism to move circumferentially along the pressure pipeline. During the movement, the detection probe is driven to move and abut against the outer wall of the pressure pipeline by the first sliding driving member to obtain the hardness data at this place, so as to realize the multi-point automatic hardness detection of the pressure pipeline; compared with the traditional manual detection method, the overall operation efficiency of the hardness detection of the pressure pipeline is effectively improved.

[0012] Preferably, the pipe-holding assembly includes two arc-shaped clamping rods and two rotary driving members arranged on the driving bracket. The two arc-shaped clamping rods are respectively rotatably connected to both ends of the driving bracket, and the concave surfaces of the two arc-shaped clamping rods are arranged opposite to each other; the two rotary driving members are respectively drivingly connected to the two arc-shaped clamping rods, and the rotary driving member is used to drive the corresponding arc-shaped clamping rod to rotate;

[0013] The driving assembly includes a Mecanum wheel trolley arranged on the driving bracket; the Mecanum wheel trolley is located below the support frame body.

[0014] By adopting the above technical solution, when installing the hardness detection device on the pressure pipeline, the support frame body is moved to abut the Mecanum wheel trolley against the surface of the pressure pipeline, and the two arc-shaped clamping rods of the holding assembly are respectively located on both sides of the pressure pipeline; the two rotary driving members are respectively used to drive the corresponding arc-shaped clamping rods to swing towards the direction close to the pressure pipeline, so as to hold the pressure pipeline by the two arc-shaped clamping rods, realizing the connection between the driving mechanism and the pressure pipeline; through the setting of the Mecanum wheel trolley, after the pressure pipeline is held by the pipe-holding assembly, the Mecanum wheel trolley can cooperate with the pipe-holding assembly to drive the support frame body to rotate circumferentially around the pipeline, so as to facilitate the multi-point hardness detection of the pressure pipeline by the detection mechanism on the support frame body; at the same time, the Mecanum wheel trolley can cooperate with the pipe-holding assembly to drive the support frame body to move along the axial direction of the pressure pipeline, facilitating the flexible movement of the hardness detection device to the next detection area of the pressure pipeline, and there is no need to frequently disassemble and assemble the hardness detection device, effectively improving the convenience of the hardness detection device during the detection operation.

[0015] Preferably, two groups of driving mechanisms are provided, and the two groups of driving mechanisms are respectively connected to the front and rear ends of the support frame body.

[0016] By adopting the above technical solution, the support frame is supported and limited by the driving mechanisms at the front and rear ends of the support frame, which is conducive to making the hardness detection device more stable when moving along the circumference of the pressure pipeline or along the axial direction of the pressure pipeline.

[0017] Preferably, the drive assembly further includes a second sliding drive member, which is drivingly connected to the Mecanum wheel trolley and is used to drive the Mecanum wheel trolley to move in a direction perpendicular to the plane where the support frame is located.

[0018] By adopting the above technical scheme, in the process of the hardness detection device moving along the axial direction of the pressure pipe through the cooperation of the front and rear end driving mechanisms, when encountering obstacles such as pipeline flanges, the third sliding drive member at the front end driving mechanism of the support frame can first drive the corresponding Mecanum wheel trolley away from the surface of the pressure pipe, and at the same time, the pipe holding assembly at the front end driving mechanism can release the holding of the pressure pipe to release the connection between the front end driving mechanism and the pressure pipe; then the rear end driving mechanism of the support frame continues to drive the support frame to continue to move along the axial direction of the pressure pipe, and after the support frame and the front end driving mechanism have passed the obstacle, the connection between the front end driving mechanism and the pressure pipe is restored, and the connection between the rear end driving mechanism and the pressure pipe is released, and the front end driving mechanism drives the support frame to drive the rear end driving mechanism to continue to move along the axial direction of the pressure pipe until the rear end driving mechanism passes over the obstacle, and finally the connection between the rear end driving mechanism and the pressure pipe is restored, so that the hardness detection device can climb over the obstacle, effectively ensuring the obstacle-crossing ability of the hardness detection device during the movement of the pressure pipe.

[0019] Preferably, a plurality of universal wheels are evenly arranged on the inner concave surface of the arc-shaped clamping rod.

[0020] By adopting the above technical solution, when the pressure pipe is held by the pipe holding assembly, the corresponding arc clamp rod is driven by the rotary drive member to swing in the direction close to the pressure pipe, and the universal wheel on the arc clamp rod is abutted against the surface of the pressure pipe; subsequently, when the Mecanum wheel trolley of the driving mechanism cooperates with the pipe holding assembly to drive the support frame to rotate circumferentially along the pressure pipe or move along its axial direction, the universal wheel can rotate accordingly, effectively reducing the friction between the arc clamp rod and the pressure pipe, and limiting the interference of the pipe holding assembly with the movement of the hardness detection device on the pressure pipe.

[0021] Preferably, the arc-shaped clamping rod is provided with a third sliding driving member corresponding to the universal wheel, and the third sliding driving member is drivingly connected to the corresponding universal wheel for driving the corresponding universal wheel to move towards or away from the inner concave surface of the arc-shaped clamping rod.

[0022] By adopting the above technical solution, when the diameter of the pressure pipeline to be detected changes, the corresponding universal wheel can be driven to move by the third sliding drive member, so that the universal wheel can abut against the outer periphery of the pressure pipeline, which is beneficial to improving the overall adaptability of the hardness detection device.

[0023] Preferably, a cleaning mechanism is further included. The cleaning mechanism is arranged on the support frame body. The cleaning mechanism includes two cleaning components. The two cleaning components are respectively located on the opposite sides of the detection mechanism. The cleaning component includes a brushing part and a fourth sliding drive member. The fourth sliding drive member is drivingly connected to the brushing part and is used to drive the brushing part to move in a direction perpendicular to the plane where the support frame body is located.

[0024] By adopting the above technical solution, when the pressure pipeline is exposed to the external environment for a long time, sundries such as bird droppings are likely to adhere to its surface, which is extremely likely to interfere with the contact of the detection probe of the subsequent hardness tester; through the setting of the cleaning mechanism, before the hardness of the pressure pipeline is detected by the detection mechanism, first, the fourth sliding drive member drives the brushing part to move and abut against the surface of the pressure pipeline, and then the driving mechanism drives the support frame body to drive the two brushing parts to move along the circumferential direction of the pressure pipeline, so as to remove the sundries adhering to the surface of the pressure pipeline through the brushing part, which is beneficial to reducing the interference of the sundries adhering to the outer periphery of the pressure pipeline on the subsequent hardness tester detection probe.

[0025] Preferably, the brushing part includes a support plate and a steel wool brush, and the steel wool brush is connected to the bottom of the support plate.

[0026] By adopting the above technical solution, through the setting of the steel wool brush, it is beneficial for the brushing part to better brush off the sundries on the surface of the pressure pipeline.

[0027] Preferably, the cleaning mechanism further includes a flushing air pipe, and the flushing air pipe is externally connected to a gas source; the flushing air pipe is arranged vertically downward and is arranged close to the detection mechanism.

[0028] By adopting the above technical solution, during the process that the driving mechanism drives the support frame body to drive the two brushing parts to move along the circumferential direction of the pressure pipeline to brush off the sundries on the outer periphery of the pressure pipeline, compressed air is blown towards the pipeline surface by using the flushing air pipe to assist in blowing off the sundries remaining on the surface of the pressure pipeline, which is convenient for more thoroughly removing the sundries on the surface of the pressure pipeline.

[0029] Preferably, the base is provided with a connecting sleeve for the detection probe. The detection probe passes through the connecting sleeve, and a limiting bolt is threadedly arranged on the outer periphery of the connecting sleeve, and the limiting bolt abuts tightly against the detection probe.

[0030] By adopting the above technical solution, the detection probe can be stably installed on the base, which reduces the possibility of the detection probe falling off when the supporting frame rotates circumferentially around the pressure pipe. At the same time, the detection probe can be detachably installed on the base. When the hardness testing device is subsequently transported and stored, the detection probe of the hardness tester can be taken out and stored separately to reduce the possibility of it being damaged by bumps.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. The driving assembly cooperates with the pipe holding assembly to drive the support frame to rotate along the circumference of the pressure pipeline, so that the detection mechanism on the support frame can perform multi-point hardness detection on the pressure pipeline, effectively improving the overall hardness detection efficiency of the pressure pipeline.

[0033] 2. The Mecanum wheel trolley is used through the driving assembly. After the pressure pipe is held by the pipe holding assembly of the driving mechanism, the Mecanum wheel trolley can cooperate with the pipe holding assembly to drive the support frame to drive the detection mechanism to rotate around the pressure pipe. At the same time, the Mecanum wheel trolley can cooperate with the pipe holding assembly to drive the support frame to move along the axis of the pressure pipe, so as to flexibly move the hardness detection device to the pressure pipe detection area.

[0034] 3. By arranging driving mechanisms at both ends of the support frame, on the one hand, the driving mechanisms at the front and rear ends can be used to support and limit the support frame, which is conducive to making the subsequent hardness detection device more stable when moving around the circumference of the pressure pipeline or around the axis of the pressure pipeline; on the other hand, when the subsequent hardness detection device encounters an obstacle during its movement along the pressure pipeline, the driving mechanisms at the front and rear ends of the support frame can cooperate to climb over the obstacle.

[0045] The following further describes the present application in detail Figure 1-8 with reference to the attached drawings.

[0046] The embodiment of the present application discloses a multi-point hardness detection device for special equipment.

The cleaning mechanism is used to clean the sundries on the pipeline surface.

[0047] Referring to Figure 2 and Figure 3, the detection mechanism 2 includes a base 21, a first sliding drive member 22, and a hardness tester; the first sliding drive member 22 is connected to the support frame 1, the first sliding drive member 22 is drivingly connected to the base 21, and is used to drive the base 21 to move in a direction perpendicular to the plane where the support frame 1 is located; the hardness tester includes a main unit and a detection probe 23; the main unit of the hardness tester is fixed to the base 21 by tying with a cable tie; the base 21 is fixedly provided with a connecting sleeve 211 corresponding to the detection probe 23, the axial direction of the connecting sleeve 211 is perpendicular to the plane where the support frame 1 is located, the detection probe 23 is inserted through the connecting sleeve 211 and the contact end of the detection probe 23 extends out of the bottom of the base 21; a limit bolt 212 is threadedly inserted through the outer periphery of the connecting sleeve 211, and one end of the limit bolt 212 extends into the inner cavity of the connecting sleeve 211 and abuts against the outer side of the detection probe 23, so as to detachably install the hardness tester on the base 21. In this embodiment, the first sliding drive member 22 adopts an electric screw linear module; the hardness tester adopts an ultrasonic hardness tester.

[0048] When performing hardness detection on the pressure pipeline, the support frame 1 is moved onto the pressure pipeline. After the pipeline is held by the pipe holding assembly 31 on the driving mechanism 3, the driving assembly 32 on the driving mechanism 3 cooperates with the pipe holding assembly 31 to drive the support frame 1 to drive the detection mechanism 2 to move circumferentially around the pressure pipeline. During this period, the first sliding drive member 22 drives the base 21 to drive the detection end of the detection probe 23 to abut against the outer periphery of the pressure pipeline, so as to obtain the hardness data of the pressure pipeline through the hardness tester, and realize the automatic detection of the multi-point hardness of the pressure pipeline.

[0049] Refer to Figure 1 and Figure 4 , two groups of driving mechanisms 3 are provided, and the two groups of driving mechanisms 3 are respectively located at the front and rear ends of the support frame 1. The driving bracket 30 is welded to the end of the support frame 1, and the driving bracket 30 and the support frame 1 are integrally arranged in a T shape.

[0050] Refer to Figure 4 and Figure 5 , the pipe holding assembly 31 includes two arc-shaped clamping rods 311 and two rotary drive members 312; the two arc-shaped clamping rods 311 are respectively rotatably connected to opposite ends of the driving bracket 30, and the concave surfaces of the two arc-shaped clamping rods 311 are arranged opposite to each other; the two rotary drive members 312 are respectively installed at both ends of the driving bracket 30, and the two rotary drive members 312 are respectively drivingly connected to the ends of the two arc-shaped clamping rods 311 to drive the corresponding arc-shaped clamping rods 311 to rotate. In this embodiment, the rotary drive member 312 adopts a reduction motor.

[0051] Refer to Figure 4 and Figure 6The driving assembly 32 includes a second sliding driving member 322 and a Mecanum wheel trolley 321; the Mecanum wheel trolley 321 is located below the support frame 1; the second sliding driving member 322 is mounted on the driving bracket 30 and the second sliding driving member 322 is drivingly connected to the corresponding Mecanum wheel trolley 321, and is used to drive the corresponding Mecanum wheel trolley 321 to move in a direction perpendicular to the plane of the support frame 1. In the embodiment, the second sliding driving member 322 adopts an electric screw linear module.

[0052] Reference Figure 4 and Figure 5 A plurality of universal wheels 33 are also installed on the inner concave surface of the arc clamping rod 311, and the plurality of universal wheels 33 are arranged away from the inner concave surface of the arc clamping rod 311, and the plurality of universal wheels 33 are evenly distributed along the arc clamping rod 311, and the arc clamping rod 311 is provided with a plurality of third sliding drive members 34 corresponding to the plurality of universal wheels 33, the third sliding drive member 34 is installed on the outer convex side of the arc clamping rod 311 and the third sliding drive member 34 is drivingly connected with the corresponding universal wheel 33, and is used for driving the corresponding universal wheel 33 to move toward or away from the inner concave surface of the arc clamping rod 311. In the present embodiment, the third sliding drive member 34 adopts an electric cylinder.

[0053] Reference Figure 5 and Figure 7 When the hardness testing device is installed on the pressure pipe, the support frame 1 is moved so that the Mecanum wheels at both ends of the support frame 1 abut against the surface of the pressure pipe, and the two arc clamping rods 311 of the driving mechanism 3 are respectively located on both sides of the pressure pipe, and the corresponding arc clamping rods 311 are driven to move toward the direction close to the pressure pipe by the rotary driving parts 312 at both ends of the driving bracket 30 until the universal wheels 33 at the arc clamping rods 311 abut against the surface of the pressure pipe, thereby completing the holding of the pressure pipe by the pipe holding assembly 31.

[0054] The drive assembly 32 uses a Mecanum wheel trolley 321 in conjunction with a second sliding drive member 322, and utilizes the omnidirectional movement characteristics of the Mecanum wheel trolley 321; on the one hand, after the pipe holding assembly 31 completes holding of the pressure pipe, the Mecanum wheel trolley 321 can cooperate with the pipe holding assembly 31 to drive the support frame 1 to move circumferentially around the pressure pipe, so that the support frame 1 can obtain hardness data of different areas of the periphery of the pressure pipe through the detection mechanism 2; on the other hand, the Mecanum wheel trolley 321 can cooperate with the pipe holding assembly 31 to drive the support frame 1 and the detection mechanism 2 to move as a whole along the axial direction of the pressure pipe, so that the hardness detection device can be quickly moved to any detection area of ​​the pressure pipe without the need to frequently disassemble and assemble the hardness detection device.

[0055] Through the setting of the universal wheels 33, when holding the pressure pipeline by the pipe-holding assembly 31, the swing drive members 312 at both ends of the drive bracket 30 drive the corresponding arc-shaped clamping rods 311 to swing towards the direction close to the pressure pipeline until the universal wheels 33 on the concave surface of the arc-shaped clamping rods 311 abut against the surface of the pressure pipeline. Subsequently, when the Mecanum wheel trolley 321 cooperates with the pipe-holding assembly 31 to drive the support frame body 1 to move circumferentially around the pressure pipeline or move in the axial direction of the pressure pipeline, the universal wheels 33 can roll accordingly, effectively reducing the friction force between the arc-shaped clamping rods 311 and the pressure pipeline, which is beneficial to the subsequent movement of the hardness detection device on the pressure pipeline to be more smooth.

[0056] By setting the third sliding drive member 34 for driving the movement of the universal wheels 33, subsequently, when the outer diameter of the pressure pipeline changes, the position of the universal wheels 33 can be adjusted by the third sliding drive member 34 so that the universal wheels 33 can better abut against the outside of the pressure pipeline.

[0057] Refer to Figure 5 、 Figure 7 and Figure 8 As shown in, drive mechanisms 3 are provided at both the front and rear ends of the support frame body 1. On the one hand, the support frame body 1 can be supported and limited by the cooperation of the drive mechanisms 3 at the front and rear ends, which is beneficial to the subsequent movement of the support frame body 1 on the pressure pipeline to be more stable and smooth. On the other hand, the hardness detection device is enabled to have the ability to cross obstacles. When the hardness detection device is moving along the axial direction of the pressure pipeline and encounters obstacles such as connecting flanges, the connection with the pressure pipeline is released by the drive structure at the front end of the support frame body 1. Specifically, the second sliding drive member 322 at the drive mechanism 3 at the front end of the support frame body 1 drives the corresponding Mecanum wheel trolley 321 to move so that the Mecanum wheel trolley 321 is separated from the surface of the pressure pipeline. At the same time, the swing drive member 312 at the drive mechanism 3 at the front end of the support frame body 1 drives the arc-shaped clamping rod 311 to swing away from the pressure pipeline so that the arc-shaped clamping rod 311 is away from the surface of the pressure pipeline; then the drive mechanism 3 at the rear end of the support frame body 1 drives the support frame body 1 and the front-end drive mechanism 3 to continue to move along the axial direction of the pressure pipeline. After the front-end drive mechanism 3 and the support frame body 1 both cross the obstacle, while restoring the connection between the front-end drive mechanism 3 and the pressure pipeline, the connection between the rear-end drive mechanism 3 and the pressure pipeline is released, and the front-end drive mechanism 3 drives the support frame body 1 to drive the rear-end drive mechanism 3 to continue to move until the rear-end drive mechanism 3 crosses the obstacle, and finally the connection between the rear-end drive mechanism 3 and the pressure pipeline is restored again to realize the obstacle-crossing operation of the hardness detection mechanism 2.

[0058] Refer to Figure 1 and Figure 2, the cleaning mechanism includes two cleaning components 4, which are respectively supported on opposite sides of the support frame 1, and the detection mechanism 2 is located between the two cleaning components 4; when the support frame 1 is installed on the pressure pipeline through the front and rear drive mechanisms 3 at both ends, the two cleaning components 4 are located on opposite sides in the axial direction of the pressure pipeline.

[0059] The cleaning component 4 includes a support 40, a brushing part 41 and a fourth sliding drive 43; the support 40 is welded to the outside of the support frame 1; the brushing part 41 includes a support plate 411 and a steel wool brush 412, the steel wool brush 412 is fixed to the bottom of the support plate 411, and both ends of the support plate 411 are slidably connected to the support 40 through a slide rail and slider structure, and the sliding direction of the support plate 411 is perpendicular to the plane where the support frame 1 is located; the fourth sliding drive rod is installed on the top of the base 21 and the fourth sliding drive 43 is drivingly connected to the support plate 411, and is used to drive the support plate 411 to drive the steel wool brush 412 to move in a direction perpendicular to the plane where the support frame 1 is located.

[0060] Through the setting of the cleaning component 4, when the hardness data on the surface of the pressure pipeline is obtained by the detection mechanism 2 on the support frame 1 subsequently, first, the fourth sliding drive 43 at the two cleaning components 4 drives the support plate 411 to drive the steel wool brush 412 to abut against the surface of the pressure pipeline, and the front and rear drive mechanisms 3 at both ends of the support frame 1 cooperate to drive the support frame 1 to rotate circumferentially around the pipeline. During the rotation of the support frame 1, the steel wool brushes 412 of the two brushing parts 41 brush off sundries such as bird droppings or rust blocks attached to the surface of the pressure pipeline, reducing the interference of sundries on the surface of the pressure pipeline and other situations for the subsequent detection mechanism 2 to obtain the hardness data on the surface of the pressure pipeline.

[0061] Refer to Figure 2 and Figure 3 , the cleaning mechanism further includes two flushing air pipes 5, both of the two flushing air pipes 5 are fixed on the support frame 1 through clamps, and the flushing air pipes 5 are arranged vertically downward; the two flushing air pipes 5 are located between the two cleaning components 4 and both of the two flushing air pipes 5 are arranged close to the detection mechanism 2. The support frame 1 is equipped with a gas source corresponding to the two flushing air pipes 5, and both of the two flushing air pipes 5 are connected to the gas source.

[0062] Through the setting of the flushing air pipes 5, during the process of subsequently brushing the sundries on the surface of the pressure pipeline by the steel wool brushes 412 of the two cleaning components 4 driven by the support frame 1, compressed air is blown towards the surface of the pressure pipeline through the flushing air pipes 5 to blow off the remaining sundries on the surface of the pressure pipeline, which is beneficial to more thoroughly clean the sundries on the surface of the pressure pipeline.
