DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined object, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0020] In view of the problem that the metal powder debris generated in the light reflection process of the existing pressure pipeline detection device is not cleaned in time, and manual cleaning is time-consuming and laborious, the present application designs a special equipment pressure pipeline quality detection device capable of automatically collecting metal powder debris, which is described in detail below.

[0021] In the traditional pressure pipeline detection process, manual feeding and discharging has the problem of low efficiency, and the manual operation speed is difficult to meet the demand of rapid detection in large-scale industrial production. At the same time, manual feeding and discharging also has certain labor danger, and the operator may be injured by heavy objects when carrying heavy pipelines, and there is a risk of being pinched by machines when operating around the equipment. Therefore, the present embodiment proposes a special equipment pressure pipeline quality detection device to improve the detection efficiency and reduce the labor intensity and danger.

[0022] Please refer to Figures 1-7 ​The embodiment provides a special equipment pressure pipeline quality detection device, which comprises a detection table 10, a detection table 10 provided with a detection station; a feeding mechanism 20, the feeding mechanism 20 is arranged on one side of the detection table 10, and is used for conveying a pipeline to the detection station; a discharging mechanism 30, the discharging mechanism 30 is arranged on the other side of the detection table 10, and is used for conveying the pipeline from the detection station; a testing mechanism 40, the testing mechanism 40 is arranged on the upper side of the detection table 10, and is used for detecting the hardness of the pipeline; wherein the detection station is provided with a positioning groove 11 for placing the pipeline, the positioning groove 11 is provided with an ejection mechanism 50, the ejection mechanism 50 has a first state and a second state; when the ejection mechanism 50 is in the first state, the pipeline is accommodated in the positioning groove 11; when the ejection mechanism 50 is in the second state, the ejection mechanism 50 acts on the pipeline, so that the pipeline moves away from the positioning groove 11 to the discharging mechanism 30.

[0023] It can be understood that the special equipment pressure pipeline quality detection device of the embodiment, the detection table 10 as a core platform, sets the detection station for receiving the pipeline and detecting the pipeline; the feeding mechanism 20 is connected with one side of the detection table 10, and is responsible for accurately conveying the pipeline to be detected to the detection station; the discharging mechanism 30 is located on the other side of the detection table 10, and is used for moving the pipeline away from the detection station after detection is completed. The positioning groove 11 on the detection table 10 provides a stable placing position for the pipeline, ensures that the position of the pipeline is fixed during detection, and ensures that the testing mechanism 40 can accurately act on the pipeline. The ejection mechanism 50 is the key to realize automatic discharging. In the first state, the pipeline can be stably accommodated in the positioning groove 11; when the detection is completed and switched to the second state, the ejection mechanism 50 acts on the pipeline by using the elastic principle, gives the pipeline an action force in the direction of the discharging mechanism 30, so that the pipeline moves away from the positioning groove 11 and smoothly moves to the discharging mechanism 30, and the discharging action is completed.

[0024] In a possible implementation process, the pipeline to be detected is conveyed to the detection station from one side of the detection table 10 under the action of the feeding mechanism 20, and is stably placed in the positioning groove 11 of the detection table 10. At this time, the ejection mechanism 50 is in the first state, so that the pipeline can be accurately positioned and stably placed, and preparation is made for subsequent detection. The testing mechanism 40 starts to work, detects the hardness of the pipeline located in the detection station, that is, applies a detection force to the corresponding part of the pipeline or uses other detection means to obtain relevant data of the hardness of the pipeline, and completes the quality detection task. When the detection is completed, the ejection mechanism 50 is switched to the second state, an upward ejection force is generated and acts on the bottom of the pipeline, the pipeline overcomes the restraint force of the positioning groove 11, moves away from the limitation of the positioning groove 11, and moves towards the discharging mechanism 30. After receiving the pipeline, the discharging mechanism 30 carries the pipeline away from the detection area, so as to make space for the detection of the next pipeline. The whole feeding and discharging and detection process is circularly performed.

[0025] In some embodiments, the feeding mechanism 20 can be a conveyor belt type, which includes a motor, a driving roller, a driven roller, a conveyor belt and a support frame. The motor drives the driving roller to rotate, which in turn drives the conveyor belt to move, thereby conveying the pipes placed on the conveyor belt to the detection station of the detection table 10. Specifically, the pipes to be detected are placed at one end of the conveyor belt. After the motor is started, the conveyor belt operates at a preset speed and direction. The pipes gradually approach the detection table 10 as the conveyor belt moves. When the pipes reach the detection station of the detection table 10, they are accurately stopped in the positioning groove 11, completing the feeding process.

[0026] In other embodiments, the feeding mechanism 20 can also be a mechanical arm type, which includes a mechanical arm body, a driving motor, an end effector (such as a gripper, a suction device, etc.) and a control system. The mechanical arm body has multiple degrees of freedom and can control its motion trajectory through programming. Specifically, the control system controls the action of the mechanical arm body according to a preset program. The driving motor drives the joints of the mechanical arm body to move, so that the end effector moves to the position of the pipe to be fed. The end effector clamps or sucks the pipe. Then, the mechanical arm body moves the pipe along the planned path and places it on the detection station of the detection table 10.

[0027] In other embodiments, the feeding mechanism 20 can also be a track type, which includes a track, a slider, a motor and a screw rod. The track is laid according to a certain path. The slider is connected to the screw rod and the track. The motor is connected to the screw rod. The slider can slide on the track. The pipe to be fed is placed on the slider. The driving device drives the slider to move along the track. Optionally, a stopper is provided on the slider, which is used to limit the movement of the pipe relative to the slider in the direction of travel and / or in the opposite direction of travel.

[0028] It can be understood that the unloading mechanism 30 can have the same structure as the feeding mechanism 20, or can have a different structure from the feeding mechanism. Preferably, both the feeding mechanism 20 and the unloading mechanism 30 are track types. However, the track of the feeding mechanism 20 has a higher height at the end closer to the detection table 10 than at the end farther from the detection table 10. The track of the unloading mechanism 30 has a higher height at the end closer to the detection table 10 than at the end farther from the detection table 10.

[0029] In some embodiments, the opening of the positioning groove 11 is upward and inclined toward the unloading mechanism 30. When the pipe is lifted by the ejecting mechanism 50, the inclined opening of the positioning groove 11 provides a component force along the inclined direction for the pipe, so that the pipe slides downward along the inclined direction under the action of gravity and moves toward the unloading mechanism 30.

[0030] In some embodiments, the ejection mechanism 50 comprises a rubber film 51 covering the bottom of the positioning groove 11 and an elastic member 52 connected to the rubber film 51 for driving the rubber film 51 to pop up; when the ejection mechanism 50 switches to the second state, the elastic member 52 pushes the rubber film 51 to deform, thereby pushing the pipe out of the positioning groove 11 upward and making it roll to the unloading mechanism 30 along the inclined direction. Optionally, the elastic member 52 is a spring.

[0031] It can be understood that the rubber film 51 covers the bottom of the positioning groove 11, and the elastic member 52 is connected to the rubber film 51. When the ejection mechanism 50 is in the first state, the elastic member 52 is in a compressed or pre-tightened state, and the rubber film 51 is tightly attached to the positioning groove 11, thereby forming a stable support surface to enable the pipe to be stably placed in the positioning groove 11. When unloading is needed, the ejection mechanism 50 switches to the second state, and the elastic member 52 releases its stored elastic potential energy to generate an upward pushing force to drive the rubber film 51 to pop up, and the upward movement of the rubber film 51 pushes the pipe up from below to overcome the friction between the pipe and the positioning groove 11 and the action of gravity, so that the pipe is released from the restraint of the positioning groove 11 and rolls to the unloading mechanism 30 along the predetermined direction under the guidance of the inclined angle of the opening of the positioning groove 11.

[0032] Further, the ejection mechanism 50 further comprises a connecting sleeve 53, a connecting line 54, a winding wheel 55, and a first driving device 56. The bottom of the positioning groove 11 is provided with a mounting groove 12, one end of the elastic member 52 is connected to the bottom of the mounting groove 12, the bottom of the mounting groove 12 is provided with an annular groove, the connecting sleeve 53 is sleeved on the outside of the elastic member 52 and slidably embedded in the annular groove, the connecting sleeve 53 is connected to the rubber film 51, one end of the connecting line 54 is connected to the connecting sleeve 53, the other end of the connecting line 54 is connected to the winding wheel 55, and the first driving device 56 is drivingly connected to the winding wheel 55. When the ejection mechanism 50 is in the first state, the first driving device 56 drives the winding wheel 55 to rotate forward by a preset number of turns to shorten the connecting line 54 between the connecting sleeve 53 and the winding wheel 55, the elastic member 52 is compressed and limited by the connecting sleeve 53 in the mounting groove 12, and the rubber film 51 is attached to the positioning groove 11. When the ejection mechanism 50 is in the second state, the first driving device 56 releases the limitation on the winding wheel 55, and the elastic force of the elastic member 52 drives the winding wheel 55 to rotate reversely to elongate the connecting line 54 between the connecting sleeve 53 and the winding wheel 55, and the connecting sleeve 53 is pushed by the elastic member 52 into the positioning groove 11 to make the rubber film 51 pop up. The winding wheel 55 and the first driving device 56 can be arranged inside the detection table 10.

[0033] It can be understood that the feeding mechanism 20 delivers the pipe to the detection station of the detection table 10, at this time the ejection mechanism 50 is in the first state, and the test mechanism 40 detects the hardness of the pipe. After the detection is completed, the control system triggers the ejection mechanism 50 to switch to the second state, the first driving device 56 releases the restriction on the winding wheel 55, the elastic restoring force of the elastic member 52 drives the winding wheel 55 to rotate in the opposite direction, the connecting line 54 is released, the connecting sleeve 53 slides outward along the annular groove, the connecting sleeve 53 pushes the rubber film 51 to deform upward and bulge, and the rubber film 51 lifts the pipe to make the pipe separate from the positioning groove 11. In the embodiment, through the forward and reverse driving control of the first driving device 56 on the winding wheel 55, the length of the connecting line 54 can be adjusted, so that the compression and release degree of the elastic member 52 is accurately controlled, and the lifting and resetting actions of the rubber film 51 are accurate and synchronous, which helps to improve the reliability and stability of the unloading action.

[0034] In some embodiments, due to the fatigue and reduced elasticity of the elastic member 52 caused by long-term use of the ejection mechanism 50, a new elastic member 52 needs to be replaced. In the embodiment, one end of the elastic member 52 abuts against the bottom of the mounting groove 12, and the other end abuts against the inside of the connecting sleeve 53. When the elastic member 52 needs to be replaced, the connecting sleeve 53 needs to be removed to replace the new elastic member 52. In order to cope with the above situation and meet the demand of convenient replacement of the elastic member 52, the thickness of the wall of the connecting sleeve 53 is the same as the groove width of the annular groove, the connecting sleeve 53 is provided with a first hook for hanging one end of the connecting line 54, and the slot of the mounting groove 12 is provided with a second hook for hanging one end of the connecting line 54. Thus, when the new elastic member 52 needs to be replaced, the connecting sleeve 53 can be lifted by external force and the first hook of the connecting sleeve 53 and the connecting line 54 can be separated, and then one end of the connecting line 54 can be connected to the second hook of the mounting groove 12. At this time, the connecting sleeve 53 can be smoothly taken out of the annular groove and the mounting groove 12, and the connecting line 54 can be kept at the second hook and taken out to be connected to the first hook of the connecting sleeve 53 again. After the new elastic member 52 is replaced, the ejection force of the ejection mechanism 50 is restored, the rubber film 51 can normally lift the pipe, the unloading reliability is guaranteed, and the normal operation and detection quality of the detection device are maintained.

[0035] In some embodiments, the first driving device 56 includes a first driving motor and a shaft coupling, the first driving device 56 is connected to the shaft coupling, and the shaft coupling is connected to the winding wheel 55.

[0036] In some embodiments, the testing mechanism 40 comprises a rack 41, a hardness tester 43, and a second driving device 42 for driving the hardness tester 43 to move in the vertical direction. The second driving device 42 drives a fixed block 44 to move in the vertical direction, and the hardness tester 43 moves synchronously. The rack 41 provides guidance and support for the fixed block 44, ensures the stable and linear movement of the fixed block 44 and the hardness tester 43 in the vertical direction, avoids the hardness tester 43 from deviating or shaking during the detection process, and ensures the accuracy of the detection results.

[0037] In some embodiments, the second driving device 42 comprises a second driving motor 421 and a driving wheel 422, a first synchronous wheel 423, a second synchronous wheel 424, a first screw rod 425, a second screw rod 426, a first sliding block 427, a second sliding block 428, and the fixed block 44. The rack 41 comprises a first vertical column and a second vertical column arranged on both sides of the testing station, and a cross beam 413 connected between the first vertical column and the second vertical column. The second driving motor 421 is installed on the cross beam 413, and the output shaft of the second driving motor 421 is vertical. The driving wheel 422 is connected to the power output end of the second driving motor 421, so that the driving wheel 422 can rotate in the horizontal plane under the drive of the second driving motor 421. The first screw rod 425 and the second screw rod 426 are vertically and rotatably installed on the first vertical column 411 and the second vertical column 412, respectively. The first synchronous wheel 423 is sleeved on the first screw rod 425, and the second synchronous wheel 424 is sleeved on the second screw rod 426. The driving wheel 422, the first synchronous wheel 423, and the second synchronous wheel 424 are connected through a synchronous belt 429, so that when the driving wheel 422 rotates, the first synchronous wheel 423 and the second synchronous wheel 424 can be driven to rotate, and the first screw rod 425 and the second screw rod 426 rotate. The first sliding block 427 and the second sliding block 428 are movably connected to the first vertical column 411 and the second vertical column 412 in the vertical direction, respectively. The first sliding block 427 is threadedly connected with the first screw rod 425, and the second sliding block 428 is threadedly connected with the second screw rod 426. The fixed block 44 is connected between the first sliding block 427 and the second sliding block 428. Therefore, when the second driving motor 421 works, the first screw rod 425 and the second screw rod 426 will synchronously rotate under the transmission, so that the first sliding block 427 and the second sliding block 428 synchronously move in the vertical direction, and the fixed block 44 translates in the vertical direction. The hardness tester 43 is connected to the lower side of the fixed block 44.

[0038] In some embodiments, a fixed block 44 is arranged between the second driving device 42 and the hardness tester 43, two ends of the fixed block 44 are slidingly connected to two sides of the rack 41 respectively, and the hardness tester 43 is connected to a side of the fixed block 44 facing the test station; wherein a mechanical switch is arranged at the limit stroke of upward movement of the fixed block 44, and the mechanical switch is electrically connected between the power supply and the first driving device 56; when the fixed block 44 is not at the limit stroke of upward movement, the mechanical switch is in a closed state, the power supply and the first driving device 56 are in a loop state, and the ejection mechanism 50 is in the first state; when the fixed block 44 is at the limit stroke of upward movement, the mechanical switch is in an open state due to being contacted by the fixed block 44, the power supply and the first driving device 56 are in an open circuit state, and the ejection mechanism 50 is in the second state; the first driving device 56 is configured to drive the winding wheel 55 to rotate forward by a preset number of turns each time it is powered on.

[0039] Specifically, when it is necessary to detect the hardness of the pipe, the second driving device 42 drives the fixed block 44 and the hardness tester 43 to move downward along the vertical direction to the detection position, at this time the mechanical switch is in a closed state, a loop is formed between the power supply and the first driving device 56, the first driving device 56 drives the winding wheel 55 to rotate forward by a preset number of turns, the elastic member 52 is compressed, the rubber film 51 is attached to the positioning groove 11, the ejection mechanism 50 is in the first state, the pipe is stably placed in the positioning groove 11, and the test mechanism 40 detects the hardness of the pipe. After detection is completed, the second driving device 42 drives the fixed block 44 and the hardness tester 43 to move upward along the vertical direction until the fixed block 44 reaches the limit stroke of upward movement, triggering the mechanical switch to be in an open state, cutting off the circuit between the power supply and the first driving device 56, and stopping the first driving device 56 from working, the elastic force of the elastic member 52 drives the winding wheel 55 to rotate reversely, pushing the rubber film 51 to deform upward, ejecting the pipe out of the positioning groove 11, and the ejection mechanism 50 is in the second state, completing the discharging action.

[0040] In some embodiments, a plurality of installation grooves 12 are uniformly arranged at the bottom of the positioning groove 11, and one elastic member 52 is arranged in each installation groove 12, the connecting sleeve 53, the connecting wire 54 and the elastic member 52 are one-to-one corresponding, and all the connecting wires 54 are connected to the same winding wheel 55.

[0041] It can be understood that, in order to further improve the stability and reliability of the ejection mechanism 50, ensure that the pipeline is uniformly stressed during ejection, and avoid pipeline damage or ejection direction deviation caused by uneven local stress, a plurality of mounting grooves 12 are uniformly arranged at the bottom of the positioning groove 11 in the embodiment, and an elastic element 52 is arranged in each mounting groove 12. One end of the elastic element 52 is connected to the bottom of the mounting groove 12, and the other end is connected to the connecting sleeve 53. The connecting sleeve 53 is sleeved outside the elastic element 52 and embedded in the annular groove. One end of the connecting line 54 is connected to the connecting sleeve 53, and the other end is connected to the winding wheel 55. When the winding wheel 55 rotates, the movement of all connecting sleeves 53 is synchronously controlled through the connecting line 54, and the compression and expansion of all elastic elements 52 are synchronously driven, so that the rubber film 51 uniformly rises or adheres to the positioning groove 11. All connecting lines 54 are connected to the same winding wheel 55, and the forward and reverse rotation of the winding wheel 55 is uniformly controlled by the first driving device 56. When the winding wheel 55 rotates forward, all connecting lines 54 are synchronously shortened, driving the connecting sleeve 53 to move synchronously and compress the elastic element 52; when the winding wheel 55 rotates reversely, all connecting lines 54 are synchronously lengthened, driving the connecting sleeve 53 to move synchronously and release the elastic element 52.

[0042] In some embodiments, the central axis of any mounting groove 12 is positioned along the vertical direction or deviated from the central axis direction of the slot opening of the positioning groove 11, that is, the elastic force of the elastic element 52 can only provide upward elastic force and movement direction to the pipeline.

[0043] In some embodiments, the peripheral edge of the rubber film 51 is sealingly connected to the positioning groove 11. It can be understood that the peripheral edge of the rubber film 51 and the positioning groove 11 can be sealingly connected in various ways, such as bonding, clamping, welding, etc., to ensure that there is no gap between the peripheral edge of the rubber film 51 and the positioning groove 11, and to ensure that the position of the rubber film 51 in the positioning groove 11 does not deviate.

[0044] Further, the central axis of the rubber film 51 is the same as the opening direction of the positioning groove 11. Among them, the central axis of the rubber film 51 is the same as the opening direction of the positioning groove 11, which means that when the ejection mechanism 50 is in the second state, the deformation direction of the rubber film 51 is completely consistent with the direction required for the pipeline to be ejected. This alignment can ensure that the elastic force of the elastic element 52 is uniformly transmitted to the central position of the bottom of the pipeline through the rubber film 51, thereby producing the maximum ejection effect, so that the pipeline can smoothly and efficiently separate from the positioning groove 11. Conversely, if the central axis of the rubber film 51 is not consistent with the opening direction of the positioning groove 11, the elastic force of the elastic element 52 may not be effectively transmitted to the central position of the bottom of the pipeline, resulting in insufficient or uneven ejection force, affecting the pipeline discharge effect.

[0045] Further, the area of the rubber film 51 when naturally unfolded is the same as the area of the bottom surface of the positioning groove 11. In the second state of the ejection mechanism 50, the elastic member 52 releases the elastic potential energy, and the rubber film 51 uniformly bulges upward, and the matching of the area of the rubber film 51 and the area of the bottom surface of the positioning groove 11 ensures the uniform lifting force on the bottom of the pipe, avoiding uneven local stress.

[0046] In some embodiments, clamping devices are further arranged on both sides of the positioning groove 11, and the clamping devices are used to clamp the pipe in the detection station, and the line between the two clamping devices is perpendicular to the running direction of the pipe. How to arrange the clamping devices is prior art, and will not be described here.

[0047] Further, the axis direction of the pipe is perpendicular to the running direction of the pipe.

[0048] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above embodiments, which does not depart from the technical solution of the present application, is still within the scope of the present application.
