Description

Technical Field

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

[0002] As a special equipment, the pressure pipeline conveys flammable and explosive media. To ensure the safety and reliability of the pressure pipeline during use, it is necessary to inspect it regularly.

[0003] One of the inspection contents of pressure pipelines includes hardness testing of pressure pipelines. Specifically, a hardness tester is used to obtain hardness data at multiple locations within a specific area of ​​the pressure pipeline to determine whether the overall strength, wear resistance, and fatigue resistance of the pressure pipeline meet the requirements.

[0004] At present, the operation process of obtaining the hardness data of the pressure pipeline through the hardness tester is mainly completed manually. Specifically, after the operator arrives at the pressure pipeline to be tested area, the hardness tester's detection probe contacts the outer wall of the pressure pipeline along the circumference of the pressure pipeline for multiple times to obtain the corresponding hardness data of the pressure pipeline.

[0005] With respect to the above-mentioned related technologies, in the actual operation of the above-mentioned detection method, in order to improve the detection accuracy, the detection probe of the hardness tester needs to be moved manually and frequently to make it contact different positions around the pressure pipe. On the one hand, the overall operation efficiency is low. On the other hand, during the detection process, some pressure pipes are located at a higher position, so the operator needs to use auxiliary tools to complete the detection work. The overall operation is relatively inconvenient. Therefore, there is room for improvement. Summary of the invention

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

[0007] The present application provides a multi-point hardness testing device for special equipment, which adopts the following technical solution: A multi-point hardness testing device for special equipment, comprising a support frame, a testing mechanism and a driving mechanism; The detection mechanism is arranged on the support frame, and the detection mechanism includes a base, a first sliding drive member and a hardness tester, and the hardness tester includes a detection probe, and the detection probe is connected to the base and the detection probe is perpendicular to the plane where the support frame is located; the first sliding drive 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 is located; The driving mechanism is arranged on the supporting frame, and the driving mechanism includes a driving bracket. The driving bracket is provided with a pipe holding assembly and a driving assembly. The pipe holding assembly is used to hold the pressure pipe; the driving assembly is used to cooperate with the pipe holding assembly to drive the supporting frame to move circumferentially around the pressure pipe.

[0008] By adopting the above technical solution, when testing the hardness of the pressure pipeline, the support frame is placed on the pipeline, and 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 to drive the detection mechanism to move circumferentially along the pressure pipeline. During the movement, the detection probe is driven by the first sliding drive member to move and abut against the outer wall of the pressure pipeline to obtain the hardness data at that location, thereby realizing multi-point automatic hardness detection of the pressure pipeline; compared with the traditional manual detection method, the overall operational efficiency of the pressure pipeline hardness detection is effectively improved.

[0009] Preferably, the pipe holding assembly comprises 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 the two ends of the driving bracket, and the inner 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; The driving assembly includes a Mecanum wheel trolley arranged on the driving bracket; the Mecanum wheel trolley is located below the supporting frame.

[0010] By adopting the above technical solution, when the hardness detection device is installed on the pressure pipe, the support frame is moved to make the Mecanum wheel trolley abut against the surface of the pressure pipe, and the two arc clamping rods of the holding assembly are respectively located on both sides of the pressure pipe; the corresponding arc clamping rods are respectively driven to swing in the direction close to the pressure pipe by the two rotary driving members, so that the pressure pipe is held by the two arc clamping rods, and the connection between the driving mechanism and the pressure pipe is realized; through the setting of the Mecanum wheel trolley, after the pressure pipe is held by the pipe holding assembly, the Mecanum wheel trolley can cooperate with the pipe holding assembly to drive the support frame to rotate around the pipe circumference, so as to facilitate multi-point hardness detection of the pressure pipe through the detection mechanism on the support frame; at the same time, the Mecanum wheel trolley can cooperate with the pipe holding assembly to drive the support frame to move along the axial direction of the pressure pipe, so as to facilitate the flexible movement of the hardness detection device to the next detection area of ​​the pressure pipe, without the need to frequently disassemble and assemble the hardness detection device, and effectively improve the convenience of the hardness detection device during the detection operation.

[0011] Preferably, two groups of the driving mechanisms are provided, and the two groups of the driving mechanisms are respectively connected to the front and rear ends of the support frame.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] Preferably, a plurality of universal wheels are evenly arranged on the inner concave surface of the arc-shaped clamping rod.

[0016] 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.

[0017] 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.

[0018] By adopting the above technical solution, when the diameter of the pressure pipe being tested changes, the corresponding universal wheel can be driven to move by the third sliding drive component so that the universal wheel can abut against the outer periphery of the pressure pipe, which is beneficial to improving the overall adaptability of the hardness testing device.

[0019] Preferably, it also includes a cleaning mechanism, which is arranged on the supporting frame, and the cleaning mechanism includes two cleaning components, which are respectively located on opposite sides of the detecting mechanism, and the cleaning component includes a brushing part and a fourth sliding driving member, and the fourth sliding driving 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 supporting frame is located.

[0020] By adopting the above technical solution, the pressure pipeline is exposed to the external environment for a long time, and bird droppings and other debris are easily adhered to the surface, which can easily interfere with the contact of the subsequent hardness tester detection probe; through the setting of the cleaning mechanism, before the hardness of the pressure pipeline is detected by the detection mechanism, the fourth sliding drive member first drives the brushing part to move and abut against the surface of the pressure pipeline, and then the driving mechanism drives the support frame to drive the two brushing parts to move along the circumference of the pressure pipeline, so that the debris adhered to the surface of the pressure pipeline is removed by the brushing part, which is beneficial to reduce the interference of debris adhered to the periphery of the pressure pipeline on the subsequent hardness tester detection probe.

[0021] Preferably, the scrubbing portion comprises a support plate and a steel wool brush, and the steel wool brush is connected to the bottom of the support plate.

[0022] By adopting the above technical solution and providing the steel wool brush, the scrubbing part can better remove the debris on the surface of the pressure pipe.

[0023] Preferably, the cleaning mechanism further comprises a flushing air pipe, which is connected to an external air source; the flushing air pipe is arranged vertically downward, and the flushing air pipe is arranged close to the detection mechanism.

[0024] By adopting the above technical solution, the driving mechanism drives the support frame to drive the two brushing parts to move along the circumference of the pressure pipe. In the process of brushing off the debris on the periphery of the pressure pipe, the flushing air pipe is used to blow compressed air toward the pipe surface to assist in blowing off the debris remaining on the surface of the pressure pipe, thereby facilitating more thorough removal of debris on the surface of the pressure pipe.

[0025] Preferably, the base is provided with a connecting sleeve for the detection probe, the detection probe is inserted into the connecting sleeve, a limiting bolt is threadedly inserted into the outer circumference of the connecting sleeve, and the limiting bolt is tightly pressed against the detection probe.

[0026] 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.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0028] 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.

[0029] 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.

[0039] The following is combined with Figure 1-8 This application is described in further detail.

In this embodiment, the first sliding driving member 22 adopts an electric screw linear module; the hardness tester adopts an ultrasonic hardness tester.

[0042] When performing hardness testing on a pressure pipe, the support frame 1 is moved onto the pressure pipe. After the pipe 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 pipe. 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 pipe, so as to obtain the hardness data of the pressure pipe through the hardness tester, thereby realizing automatic multi-point hardness testing of the pressure pipe.

[0043] Reference Figure 1 and Figure 4 The driving mechanism 3 is provided with two groups, 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 arranged in a T shape as a whole.

[0044] Reference Figure 4 and Figure 5 The pipe holding assembly 31 includes two arc-shaped clamping rods 311 and two rotary driving members 312; the two arc-shaped clamping rods 311 are respectively rotatably connected to the opposite ends of the driving bracket 30, and the inner concave surfaces of the two arc-shaped clamping rods 311 are arranged opposite to each other; the two rotary driving members 312 are respectively installed at the two ends of the driving bracket 30, and the two rotary driving 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 driving member 312 adopts a reduction motor.

[0045] Reference 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] Through the setting of the universal wheel 33, when the pressure pipe is held by the pipe holding assembly 31, the corresponding arc clamping rod 311 is driven by the rotary driving members 312 at both ends of the driving bracket 30 to swing in the direction close to the pressure pipe until the universal wheel 33 on the inner concave surface of the arc clamping rod 311 abuts against the surface of the pressure pipe. When the Mecanum wheel trolley 321 cooperates with the pipe holding assembly 31 to drive the support frame 1 to move around the circumference of the pressure pipe or around the axis of the pressure pipe, the universal wheel 33 can roll accordingly, effectively reducing the friction between the arc clamping rod 311 and the pressure pipe, which is conducive to smoother movement of the subsequent hardness detection device on the pressure pipe.

[0050] By providing a third sliding drive member 34 for driving the universal wheel 33 to move, when the outer diameter of the pressure pipe changes later, the position of the universal wheel 33 can be adjusted by the third sliding drive member 34 so that the universal wheel 33 can better abut against the outside of the pressure pipe.

[0051] Reference Figure 5 , Figure 7 and Figure 8 The driving mechanisms 3 are arranged at both the front and rear ends of the support frame 1. On the one hand, the support frame 1 can be supported and limited by the driving mechanisms 3 at the front and rear ends, which is conducive to the subsequent movement of the support frame 1 on the pressure pipe to be more stable and smooth. On the other hand, the hardness detection device has the ability to overcome obstacles. When the hardness detection device encounters obstacles such as connecting flanges during the movement along the axis of the pressure pipe, the connection with the pressure pipe is released through the driving structure at the front end of the support frame 1. Specifically, the second sliding drive member 322 at the driving mechanism 3 at the front end of the support frame 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 pipe. At the same time, the driving mechanism 3 at the front end of the support frame 1 The rotary driving member 312 at the position drives the arc clamping rod 311 to swing in the direction away from the pressure pipe, so that the arc clamping rod 311 is away from the surface of the pressure pipe; then the rear end driving mechanism 3 of the supporting frame 1 drives the supporting frame 1 and the front end driving mechanism 3 to continue to move along the axial direction of the pressure pipe, and after the front end driving mechanism 3 and the supporting frame 1 have passed the obstacle, the connection between the front end driving mechanism 3 and the pressure pipe is restored, and the connection between the rear end driving mechanism 3 and the pressure pipe is released, and the front end driving mechanism 3 drives the supporting frame 1 to drive the rear end driving mechanism 3 to continue to move until the rear end driving mechanism 3 passes the obstacle, and finally the connection between the rear end driving mechanism 3 and the pressure pipe is restored, thereby realizing the obstacle crossing operation of the hardness detection mechanism 2.

[0052] Reference Figure 1 and Figure 2The 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 pipe through the front and rear end driving mechanisms 3, the two cleaning components 4 are located on opposite sides of the axial direction of the pressure pipe.

[0053] The cleaning assembly 4 includes a support 40, a brushing portion 41 and a fourth sliding drive member 43; the support 40 is welded to the outer side of the support frame 1; the brushing portion 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 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 member 43 is drivingly connected to the support plate 411, which 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.

[0054] Through the setting of the cleaning component 4, when the hardness data of the surface of the pressure pipe is subsequently obtained through the detection mechanism 2 on the support frame 1, the fourth sliding driving parts 43 at the two cleaning components 4 first drive the support plate 411 to drive the steel wool brush 412 to abut against the surface of the pressure pipe, and the driving mechanisms 3 at the front and rear ends of the support frame 1 cooperate to drive the support frame 1 to rotate around the pipeline. During the rotation of the support frame 1, the steel wool brushes 412 of the two brushing parts 41 will brush off the debris such as bird droppings or rust attached to the surface of the pressure pipe, thereby reducing the situation where the debris on the surface of the pressure pipe interferes with the subsequent detection mechanism 2 in obtaining the surface hardness data of the pressure pipe.

[0055] Reference Figure 2 and Figure 3 The cleaning mechanism further includes two flushing air pipes 5, which are fixed to the support frame 1 through a clamp and are arranged vertically downward; the two flushing air pipes 5 are located between the two cleaning components 4 and are arranged close to the detection mechanism 2. The support frame 1 is provided with an air source corresponding to the two flushing air pipes 5, and the two flushing air pipes 5 are connected to the air source.

[0056] By setting up the flushing air pipe 5, in the subsequent process of brushing the debris on the surface of the pressure pipe by the steel wool brushes 412 of the two cleaning components 4 driven by the support frame 1, compressed air is blown toward the surface of the pressure pipe through the flushing air pipe 5 to blow away the debris remaining on the surface of the pressure pipe, which is conducive to more thorough cleaning of the debris on the surface of the pressure pipe.

[0057] The implementation principle of the embodiment of the present application is that when the hardness of the pressure pipe is tested by the hardness testing device, the following steps are included: S1: The hardness testing device is in place: the support frame 1 is moved onto the pressure pipe, and the Mecanum wheel trolleys 321 of the driving mechanism 3 at the front and rear ends of the support frame 1 are brought into contact with the pressure pipe, and the pressure pipe is held by the pipe holding assembly 31 at the driving mechanism 3; S2: Cleaning the detection area: The fourth sliding drive member 43 at the cleaning component 4 drives the support plate 411 to drive the steel wool brush 412 to abut against the surface of the pressure pipe; the Mecanum wheel trolley 321 cooperates with the pipe holding component 31 to drive the support frame 1 to rotate around the pipe circumference, so as to use the steel wool brush 412 at the cleaning component 4 to scrub and clean the surface of the pressure pipe, and cooperate with the flushing air pipe 5 to flush the surface of the pressure pipe; after the cleaning is completed, the fourth sliding drive member 43 at the cleaning component 4 drives the support plate 411 to drive the steel wool brush 412 to separate from the surface of the pressure pipe; S3: Hardness test: The Mecanum wheel trolley 321 cooperates with the pipe holding assembly 31 to support the frame 1 to drive the detection mechanism 2 to move around the pressure pipe. During this period, the detection mechanism 2 cooperates with the detection mechanism 2 to obtain the surface hardness data of the pressure pipe, thereby realizing multi-point hardness test on the pressure pipe.
