[0035] See also Figure 1-Figure 13 In an embodiment of the present invention, a detection device for a nickel alloy seamless pipe comprises a bracket 1 and a protective shell 2. Preferably, the protective shell 2 is installed on the bracket 1, and a conveying member for conveying the nickel alloy seamless pipe is provided below the bracket 1 corresponding to the protective shell 2. When in use, when the seamless pipe needs to be detected, the seamless pipe is placed on the conveying member and the seamless pipe is moved by the conveying member. A detector 21 for detecting the nickel alloy seamless pipe is installed in the protective shell 2, and a driving component 3 for driving the detector 21 to move is provided on the protective shell 2, and then the driving component 3 is started to allow the detector 21 to detect the seamless pipe.

[0036] In the process of inspecting nickel alloy seamless pipes, dust will inevitably adhere to the detection head of the detector 21. In order to ensure the cleanliness of the detection head and the accuracy of the detection data, a cleaning component 5 for cleaning the detection head of the detector 21 is provided on one side of the protective shell 2. In order to allow the cleaning component 5 to automatically move to clean the detection head of the detector 21, an inflation component 4 for driving the cleaning component 5 to move relative to the detector 21 is provided on the top of the cleaning component 5.

[0037] The cleaning assembly 5 includes an outer shell and a cleaning plate 53; the outer shell is fixedly arranged at the bottom end of one side of the protective shell 2, the inflatable assembly 4 is arranged on the top of the outer shell, a hollow column 55 is slidably embedded in the cleaning plate 53, the cleaning plate 53 is arranged in the outer shell through the hollow column 55, the end of the hollow column 55 away from the cleaning plate 53 passes through the side wall of the outer shell and is connected with the end of the inflatable assembly 4, a first spring 54 is arranged between the end of the cleaning plate 53 away from the protective shell 2 and the inner wall of the outer shell, a first fixing block 56 is arranged at the end of the cleaning plate 53 close to the protective shell 2, and a guide assembly 52 is arranged on the top of the inner wall of the outer shell. At the connection between the cleaning plate 53 and the first fixed block 56 corresponding to the guide component 52, a winding roller 51 corresponding to the guide component 52 is arranged on the inner wall of the shell, and cleaning paper is arranged on the winding roller 51, and a storage box 6 corresponding to the cleaning plate 53 is arranged on the bottom of the inner wall of the shell, and the side wall of the protective shell 2 close to the storage box 6 is provided with an output port for the storage box 6 to slide out the detector 21 corresponding to the storage box 6, and a clamping component is arranged on the storage box 6 to clamp the end of the cleaning paper in cooperation with the first fixed block 56, and the storage box 6 can also collect the cleaning paper after use to avoid the cleaning paper falling after use and affecting the detection work.

[0038] It should be noted that the conveying member realizes the functions of horizontal conveying of seamless pipes and rotation of seamless pipes placed thereon, and the conveying member and the detector 21 are both common devices for detecting nickel alloy seamless pipes in the prior art. The specific working principle and structure will not be described in detail here. A protrusion is provided on the storage box 6, and the protrusion is provided at the output port and is flush with the height of the first fixed block 56. When the cleaning plate 53 moves relative to the protective shell 2, the storage box 6 is pushed to move by the cooperation of the first fixed block 56 and the protrusion. The main body of the storage box 6 is a drawer-type structure that can be slidably pulled out, so that it is convenient for personnel to clean the cleaning paper after use. The winding roller 51 is assembled in the shell by personnel, and the cleaning paper wound on the winding roller 51 is specially used for cleaning the detection head of the detector 21. The guide assembly 52 includes two guide rollers and a guide plate; the two ends of the guide roller and the guide plate are connected to the shell through a fixed support plate, and the two ends of the guide roller are rotatably connected to the support plate. The two ends of the guide plate are fixedly connected to the support plate, and the end of the guide plate is inclined toward the first fixed block 56. When assembling the winding roller 51, the personnel first pulls the cleaning paper out from the winding roller 51 and passes it between the two guide rollers. Under the action of the guide plate, it hangs down between the first fixed block 56 and the clamping assembly. The guide roller can prevent the cleaning paper from wrinkling and affecting its use. There is a distance between the first fixed block 56 and the storage box 6. When the cleaning plate 53 pushes the first fixed block 56 to move relative to the protective shell 2, since the end of the cleaning paper is not clamped, the end of the cleaning paper refers to the position of the first fixed block 56 at this time, which is equivalent to moving toward the cleaning plate 53 on the first fixed block 56. However, after the movement, the clamping assembly can also clamp the end of the cleaning paper. The hollow column 55 is hollow. When the inflatable assembly 4 is driven, the cleaning plate 53 is pushed to move relative to the protective shell 2 through the hollow column 55. The bottom of the first fixed block 56 is flush with the bottom of the cleaning plate 53 and is spaced apart.

[0039] During specific use, when no detection is performed, the detector 21 is located near the top of the inner wall of the protective shell 2, and the inflation component 4 is in an uninflated state. The cleaning plate 53 is retracted in the shell under the action of the first spring 54, and the end of the cleaning paper on the winding roller 51 is between the first fixed block 56 and the clamping component, and the clamping component is in an expanded state at this time; when it is necessary to detect the seamless pipe, first start the conveying member to move to the two end positions of the bracket 1 respectively, and then place the seamless pipe on the conveying member, and then start the driving component 3 to make the detector 21 extend downward from the protective shell 2 to detect the seamless pipe, and at the same time, the driving component 3 makes the inflation component 4 move upward to inflate. When the detection of the seamless pipe is completed, the driving component 3 is used to The detector 21 moves and resets, and the inflation component 4 is triggered to squeeze the gas, driving the cleaning plate 53 to move relative to the detector 21 through the hollow column 55. The movement of the cleaning plate 53 causes the first spring 54 to be stretched. When the first fixed block 56 is in contact with the storage box 6, the clamping component clamps the end of the cleaning paper, thereby ensuring that the cleaning plate 53 can pull the cleaning paper from the winding roller 51 when it moves toward the detection head of the detector 21. Then the cleaning plate 53 pushes the storage box 6 to continue to move toward the detection head of the detector 21, and cleans the detection head with the cleaning paper. When the cleaning plate 53 moves and completes the cleaning of the detector 21, the inflation component 4 releases pressure, so that the cleaning plate 53 moves and resets under the action of the first spring 54.

[0040] like Figure 4-Figure 8 As shown, the clamping assembly includes a lower pressure plate 63; the lower pressure plate 63 is fixedly connected to the inner wall of the storage box 6 corresponding to the first fixed block 56, and a third spring is arranged between the end of the storage box 6 away from the lower pressure plate 63 and the outer shell, and the side wall of the storage box 6 is provided with a connecting column 62 for sliding, and the top of the connecting column 62 is fixedly connected to the upper pressure plate 61, and a return spring is arranged between the end of the connecting column 62 away from the upper pressure plate 61 and the inner wall of the storage box 6. When the storage box 6 is pushed by the cleaning plate 53, the return spring enables the storage box 6 to automatically return to its original position, and a protrusion is arranged on the bottom surface of one end of the storage box 6 close to the third spring, and a sliding groove adapted to the protrusion is opened at the bottom of the inner wall of the outer shell. The sliding groove and the protrusion can cooperate to limit the sliding direction and position of the storage box 6, so as to achieve a better use effect, and a dividing assembly for cutting cleaning paper is arranged above the output port in the outer shell.

[0041] Further, such as Figure 7-Figure 8 , Fig.13As shown, two groups of round rods 66 are provided at both ends of the upper pressure plate 61, and two groups of triangular blocks 65 are slidably connected in the side wall of the protective shell 2. The top of the triangular block 65 is slidably fitted with the round rod 66, and a movable plate 64 is slidably fitted on the side of the triangular block 65 close to the cleaning plate 53. The triangular block 65 can slide relative to the detector 21 in the side wall of the protective shell 2, and the end of the movable plate 64 away from the triangular block 65 is slidably embedded in the side wall of the cleaning plate 53, and the movable plate 64 can slide up and down on the side wall of the cleaning plate 53, and the bottom of the inner wall of the shell is slidably embedded near the protective shell 2. There is an L rod 10 for limiting the protrusion, and the end of the L rod 10 close to the slide groove is set with an inclined surface, and the inclined surface of the L rod 10 faces the third spring. A compression spring is arranged between the end of the L rod 10 away from the inclined surface in the horizontal direction and the outer shell, and the top end of the L rod 10 is slidably matched with one group of movable plates 64. The movable plate 64 is slidably embedded in the side wall of the cleaning plate 53 through a cylinder and a support spring. The movable plate 64 can slide up and down on the cylinder. The support spring is sleeved on the outer periphery of the cylinder and supports the movable plate 64, so that the movable plate 64 slides downward under the action of external force.

[0042] It should be noted that: Please refer to Figure 4 The lower pressing plate 63 and the first fixing block 56 are staggered so that when the first fixing block 56 is separated from the lower pressing plate 63, the upper pressing plate 61 and the lower pressing plate 63 cooperate to continuously clamp; Figure 8 The triangular block 65 is a right-angled trapezoidal structure, and the inclined surface of the triangular block 65 faces the detector 21. A through hole is opened on the side wall of the triangular block 65 close to the storage box 6. A baffle plate that is horizontal to the inclined surface of the triangular block 65 is rotatably arranged on one side of the inclined surface of the through hole. The size of the through hole allows the round rod 66 and the movable plate 64 to pass through together. The length of the extended end of the round rod 66 is greater than the width of the movable plate 64. When the round rod 66 passes through the through hole, the baffle plate will be pushed open in the direction of the detector 21, and the movable plate 64 will not contact the baffle plate when passing through the through hole. When the round rod 66 moves away from the detector 21, the movable plate 64 will not contact the baffle plate. During dynamic reset, since the upper end of the baffle is rotatably connected to the through-hole, the baffle will rotate and reset under the action of gravity after being pushed open, and the lower end of the baffle is adapted to the through-hole, so after the baffle is rotated and reset, it will cooperate with the bottom surface of the through-hole and will not rotate again, so that the round rod 66 can slide upward through the baffle on the inclined surface of the triangular block 65 to the top of the triangular block 65, and the end of the movable plate 64 close to the cleaning plate 53 is set as an inclined surface, so that when the movable plate 64 is reset, the inclined surface structure of the movable plate 64 close to the cleaning plate 53 cooperates with the through-hole, so that the movable plate 64 slides downward and resets through the through-hole.

[0043] When in use, when the inflatable component 4 does not drive the cleaning plate 53, the reset spring is in a stretched state, and the L rod 10 cooperates with one of the groups of movable plates 64 in the shell, so that the end of the L rod 10 does not extend into the slide groove, and the compression spring is compressed; when the detector 21 completes the detection and shrinks in the protective shell 2, the inflatable component 4 drives the cleaning plate 53 to move relative to the detector 21 through the hollow column 55, so that the first fixed block 56 moves relative to the storage box 6, and the movement of the cleaning plate 53 causes the movable plate 64 to push the triangular block 65 toward the direction of the detector 21. The movement of the triangular block 65 separates the top from the round rod 66, and the connection column 62 is pulled downward by the action of the reset spring, so that the upper pressure plate 61 moves downward to connect with the lower pressure plate 63 and the first The fixed block 56 cooperates to complete the clamping of the end of the cleaning paper, and the upper pressure plate 61 moves downward to make the round rod 66 move downward and press the movable plate 64 downward. At this time, the cleaning plate 53 continues to move toward the detector 21 and pushes the storage box 6 to move. The storage box 6 moves to make the protrusion slide in the slide groove. When the storage box 6 and the cleaning plate 53 move and extend into the protective shell 2 to the maximum distance, the splitting component is triggered to split the cleaning paper on the cleaning plate 53. At the same time, when the cleaning of the detection head is completed, since one group of movable plates 64 is separated from the L rod 10, the compression spring pushes the L rod 10 into the slide groove, so the protrusion will cooperate with the end of the L rod 10 and be limited by the L rod 10 when it moves, so that when the inflation component 4 is depressurized, the cleaning plate 53 is released through the first spring 54. First, it returns to the shell, and the cleaning paper has been cut, and the clamping assembly continues to clamp the cleaning paper, so the cleaning plate 53 returns to its initial state at this time. Under the action of gravity, the cut and used cleaning paper falls into the storage box 6, and the further movable plate 64 returns to its initial state with the cleaning plate 53. One group of movable plates 64 cooperates with the L rod 10 again and makes the L rod 10 move toward the compression spring, so that the end of the L rod 10 is separated from the protrusion, so that the storage box 6 is moved away from the detector 21 through the third spring, so that the round rod 66 cooperates with the inclined surface of the triangular block 65. When the cleaning plate 53 moves toward the detector 21, the movable plate 64 pushes the triangular block 65 to move toward the detector 21 on the side wall of the protective shell 2. A certain distance, so the triangular block 65 will first move in the opposite direction to the initial state when cooperating with the round rod 66, and the round rod 66 slides upward to the top of the triangular block 65 under the action of the triangular block 65 and the baffle, so that the upper pressure plate 61 moves upward and separates from the lower pressure plate 63, and the clamped end of the cleaning paper is released, and under the action of gravity, it completely falls into the storage box 6, which is convenient for collection and cleaning, and the upper pressure plate 61 moves upward to make the connecting column 62 move upward, so that the reset spring is stretched. Since the dividing component is arranged near the output port, the end of the cleaning paper will fall on the first fixed block 56 under the action of the guide plate and the length is sufficient for the clamping component to clamp after the cleaning plate 53 moves, and there is no need for personnel to manually load it every time cleaning.

[0044] like Figure 4-Figure 13As shown, the dividing assembly includes a transverse plate 9; one end of the transverse plate 9 away from the cleaning plate 53 is fixedly connected to the side wall of the protective shell 2 close to the cleaning plate 53, a fixing column 91 is slidably arranged on the transverse plate 9, and one end of the fixing column 91 close to the storage box 6 is fixedly connected to a cutting knife 93, and a second spring 95 is arranged between the cutting knife 93 and the transverse plate 9, and the transverse plate 9 is slidably embedded with a square rod 92 for limiting the movement of the fixing column 91 close to the side wall of the protective shell 2, and the square rod 92 is elastically connected to the protective shell 2, and the square rod 92 can slide in the horizontal direction relative to the transverse plate 9, and the end of the cleaning plate 53 away from the transverse plate 9 is provided with a trigger rod 94 cooperating with the square rod 92, and the trigger rod 94 can also limit the position of the cleaning plate 53, and the top of the fixing column 91 is provided with a reset mechanism for driving the fixing column 91 to move upward.

[0045] Furthermore, the reset mechanism includes a second transmission wheel 81; the top of the fixed column 91 is connected to the second transmission wheel 81 through a traction rope transmission, the second transmission wheel 81 is connected to the protective shell 2 through a connecting block, and the end of the second transmission wheel 81 away from the connecting block is connected to the first transmission wheel 8 through a belt drive, the first transmission wheel 8 is rotatably connected to the inner wall of the shell, and the end of the first transmission wheel 8 away from the shell extends into a transmission groove opened on the side of the cleaning plate 53.

[0046] It should be noted that: preferably, the square rod 92 is elastically connected to the protective shell 2 through a spring, and a limiting column is provided on the side wall of the square rod 92 corresponding to the fixed column 91. Under the action of the elastic connection between the square rod 92 and the protective shell 2, the limiting column moves relative to the fixed column 91 and extends into its side wall for limiting. The end of the first transmission wheel 8 extending into the transmission groove is provided with a gear, and the end of the transmission groove close to the trigger rod 94 is provided with teeth meshing with the gear. When the cleaning plate 53 moves relative to the protective shell 2, the first transmission wheel 8 and the L rod 10 will not contact the trigger rod 94, thereby ensuring that the cleaning plate 53 will not be stuck. One end of the traction rope is fixedly connected to the second transmission wheel 81 and the other end is fixedly connected to the fixed column 91, so that the second transmission wheel 81 pulls the fixed column 91 upward through the traction rope when it rotates.

[0047] During specific use, when the cleaning plate 53 is not driven by the inflation component 4, and the detector 21 has completed the detection and moved toward the protective shell 2, the second spring 95 is in a compressed state, the limiting column extends into the side wall of the fixed column 91 and limits the position, the cutting knife 93 is above the upper pressure plate 61, and the square rod 92 protrudes out of the side wall of the protective shell 2 under the action of elasticity; when the inflation component 4 drives the cleaning plate 53 to move relative to the detector 21, the end of the cleaning paper is clamped by the first fixed block 56 and the clamping assembly, so that the cleaning plate 53 moves through the cleaning paper to complete the cleaning of the detection head, and the trigger rod 94 moves with the cleaning plate 53 to the position of the square rod 92 and pushes the square rod 92 into the side wall of the protective shell 2, the square rod 92 moves relative to the protective shell 2, and the limiting column is separated from the fixed column 91, so that the cutting knife 93 moves relative to the cleaning plate 53 under the action of the second spring 95 resetting, and completes the cleaning. The cleaning papers are divided into pairs, so that it is convenient to store the used cleaning papers, and avoid using them again to clean the detection head uncleanly. When the cleaning is completed, the cleaning plate 53 moves to reset. At this time, the gear at the end of the first transmission wheel 8 cooperates with the teeth in the transmission groove, so that the first transmission wheel 8 drives the second transmission wheel 81 to rotate through the belt. The rotation of the second transmission wheel 81 drives the fixed column 91 to move upward by winding the traction rope. The upward movement of the fixed column 91 causes the cutting knife 93 to move upward, and the second spring 95 is compressed. Since the trigger rod 94 leaves the square rod 92, the square rod 92 is reset to the initial state under the action of the elastic connection with the protective shell 2. When the fixed column 91 moves to the limit groove thereon to correspond to the limit column, the square rod 92 moves relative to the fixed column 91 under the action of the push spring, so that the limit column and the limit groove cooperate to complete the limit, and no manual reset is required, which is convenient to use.

[0048] like Figure 1-Figure 13 As shown, the driving component 3 includes a motor 31; the motor 31 is arranged on the bracket 1, and the output end of the motor 31 is transmission-connected with a threaded rod 32, the threaded rod 32 is rotatably arranged on the protective shell 2, and the threaded rod 32 extends into the protective shell 2. The outer thread is connected to a lifting block, and the lifting block is slidably embedded in the inner wall of the protective shell 2, and the side of the lifting block away from the protective shell 2 is fixedly connected with a mounting seat for assembling the detector 21, and the end of the threaded rod 32 away from the protective shell 2 is transmission-connected with a winding roller 33, and the end of the pull rope away from the slider is fixedly connected to the winding roller 33, and a limit component for limiting the movement of the slider is slidably embedded in the top side wall of the protective shell 2.

[0049] Furthermore, the inflation component 4 includes a telescopic tube 43; the telescopic tube 43 is arranged at the top of the outer shell, and a support rod 41 is arranged at the center of the telescopic tube 43, and a counterweight block 42 is slidably arranged on the support rod 41. The end of the telescopic tube 43 away from the outer shell is fixedly connected to the counterweight block 42, and the counterweight block 42 is slidably connected to the side of the protective shell 2 close to the cleaning plate 53 through a slider, and the top of the slider is transmission-connected to the driving component 3 through a pull rope. A connecting tube 44 is arranged at the end of the telescopic tube 43 away from the counterweight block 42, and the end of the connecting tube 44 away from the telescopic tube 43 is connected to the hollow column 55. When the telescopic tube 43 is squeezed by the counterweight block 42, the cleaning plate 53 is driven to move relative to the detector 21 for cleaning through the connecting tube 44 and the hollow column 55. The limiting assembly includes a limiting rod 7; the limiting rod 7 is slidably embedded in the side wall of the protective shell 2, and a pushing plate is provided at one end of the limiting rod 7 close to the threaded rod 32. The pushing plate is slidably matched with a top plate 71 away from the bottom surface of the winding roller 33. The top plate 71 is fixedly connected to the top surface of the lifting block away from the bottom surface of the pushing plate, and a tension spring is provided between the pushing plate and the protective shell 2.

[0050] It should be noted that the support rod 41 is a hollow structure, and a first through hole connected to the telescopic tube 43 is provided at one end close to the outer shell, a second through hole is provided above the first through hole, and a one-way valve is provided at the end of the support rod 41 away from the first through hole. When the telescopic tube 43 is stretched, the one-way valve is in an open state. When the counterweight block 42 slides downward on the support rod 41 and squeezes the telescopic tube 43, the one-way valve is in a closed state. When the counterweight block 42 slides between the second through hole and the first through hole, the gas in the telescopic tube 43 enters the support rod 41 through the first through hole and is discharged through the second through hole. When the counterweight block 42 slides upward on the support rod 41 and stretches the telescopic tube 43, due to the air pressure difference generated in the telescopic tube 43, the one-way valve is in an open state, allowing outside air to enter the telescopic tube 43.

[0051] During specific use, when the detector 21 is retracted in the protective shell 2, the lifting block is close to the position of the limit rod 7, the top plate 71 cooperates with the push plate, and the end of the limit rod 7 is separated from the slider, the tension spring is stretched, the counterweight block 42 is below the second through hole, and the counterweight block 42 is compressed; when testing, the starting motor 31 drives the threaded rod 32 to rotate, and the threaded rod 32 rotates through the thread to move the lifting block downward, so that the top plate 71 moves downward and separates from the push plate. At this time, under the action of the tension spring, the push plate and the limit rod 7 The relative counterweight block 42 moves, and the lifting block moves downward through the mounting seat to enable the detector 21 to move downward to detect the workpiece. During this process, the threaded rod 32 rotates to drive the winding roller 33 to rotate. The rotation of the winding roller 33 enables the counterweight block 42 to move upward through the cooperation of the pull rope and the slider. When the slider slides to the position of the limit rod 7, it cooperates with the limit rod 7. The limit rod 7 extends into the side wall of the slider under the action of the tension spring to limit the position, so that the position of the counterweight block 42 is limited, and the counterweight block 42 moves upward to pull the telescopic tube 43 When the cam 32 is in the state of being stretched, the tension member 32 is pulled upward and the tension member 33 is pulled back to the state in which the tension member 32 is pulled. When the cam 32 is pulled downward, the tension member 32 is pulled back to the state in which the tension member 32 is pulled back to the state in which the tension member 32 is pulled back. When the cam 32 is pulled back to the state in which the tension member 32 is pulled back, the tension member 32 is pulled back to the state in which the tension member 32 is pulled back.
