Description

Technical Field

[0001] This invention belongs to the technical field of raw material tape cleaning equipment, specifically relating to an adaptive pressure gauge thread raw material tape cleaning device. Background Technology

[0002] When installing pressure gauges, to prevent leakage of liquid media in the pipeline, PTFE tape is usually wrapped around the threaded joint of the pressure gauge. The PTFE tape forms a protective layer on the threaded joint and also has the effect of preventing corrosion. Because the PTFE tape is wrapped tightly, during the calibration process of the pressure gauge, the calibration personnel need to use tools such as saw blades and knives to clean the PTFE tape from the thread surface. Existing technology has designed electric thread cleaning equipment for cleaning PTFE tape, which can reduce the difficulty of cleaning PTFE tape.

[0003] Chinese patent document CN202222663853.6 discloses a raw material tape cleaning machine, including a drive unit with a negative pressure vacuum device installed on it. The machine also includes a rotating disk and a dust collection pipe. The rotating disk is mounted on the dust collection pipe and rotates in conjunction with it. The drive end of the drive unit is linked to the rotating disk, and a brush head is mounted on the rotating disk. This raw material tape cleaning machine uses the drive unit to rotate the brush head, causing the metal bristles on the brush head to scrape off the raw material tape, reducing the difficulty of cleaning. However, this cleaning machine can only peel raw material tape from a single pressure gauge at a time. On-site inspections often require the maintenance of multiple voltmeters, and different voltmeters may have different thread sizes and materials. Existing raw material tape cleaning equipment is insufficiently adaptable to different types of voltmeters. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure gauge thread cleaning device with a simple structure and reasonable design that can adaptively adjust the pressure gauge thread to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

The inspector rotates the two pressure gauges to simultaneously peel off the PTFE tape from the threaded joints of the two pressure gauges. Before peeling off the PTFE tape using the cleaning device, the inspector can synchronously adjust the height of the two first pulleys and the first tensioning wheel through the position adjustment component to match the height of the cleaning space with the outer diameter of the threaded joint of the pressure gauge.

[0008] As a further optimization of the present invention, the position adjustment assembly includes a mounting frame fixed inside the housing, a first slider slidably disposed in the middle of the mounting frame, and second sliders slidably disposed on both sides of the first slider. The first slider is rotatably connected to two first tensioning wheels via two mounting plates. Two first pulleys are rotatably disposed at the front ends of the two second sliders. The two second pulleys and the two second tensioning wheels are rotatably connected to the mounting frame.

A third gear is meshed on both sides of the first gear, and the two third gears mesh with the two first gears respectively. A gear drive component is provided on the housing.

[0009] As a further optimization of the present invention, the gear drive component is a second motor fixed to the top of the housing, and the output end of the second motor is fixed to the top of the first lead screw. The ratio of the number of teeth of the first gear to the number of teeth of the second gear is 1 / 2. The belt between the first pulley and the second pulley and the belt between the first pulley and the first tensioning pulley are both perpendicular to the horizontal plane.

[0010] As a further optimization of the present invention, the housing is provided with a size detection component, which includes a fixed block fixed to the top of the housing and a measuring block abutting against the fixed block. A guide member is fixed to the housing and slides with the measuring block. A spring is provided between the end of the guide member away from the measuring block and the measuring block. A position sensor is provided on the side of the measuring block away from the fixed block.

[0011] As a further optimization of the present invention, the guide is a slide rail fixed to the top of the housing, a connecting rod is fixed to the end of the measuring block away from the fixed block, the connecting rod is slidably disposed on the inner side of the slide rail, the position sensor is fixed to the end of the slide rail away from the measuring block, and the top of the ends of the fixed block and the measuring block that abut against each other are both provided with chamfers.

[0012] As a further optimization of the present invention, two opposing through holes and two limiting components are provided on the front side wall of the housing. The limiting components include an electric push rod fixed to the front end of the housing and a stop plate fixed to the output end of the electric push rod. A sliding groove corresponding to the stop plate is provided on the side of the through hole near the limiting component. Two positioning detection components are provided on the front side wall of the housing, and the two positioning detection components are respectively located at the top of the two through holes.

[0013] As a further optimization of the present invention, the brush head includes an installation roller, an installation groove opened at the rear of the installation roller, an assembly hole opened at the front of the installation roller, and a metal ring fixed at the front of the installation groove. The front ends of the first pulley and the second pulley are both fixed with connecting posts corresponding to the installation groove, and the connecting posts are provided with a first electromagnet.

[0014] As a further optimization of the present invention, the housing is provided with a support component, which is located on the front side of the cleaning component. The support component includes a guide rod fixed inside the front side of the housing, two mounting frames slidably disposed on the guide rod, a plurality of first mounting holes opened on the upper part of the mounting frames, a plurality of second mounting holes opened on the lower part of the mounting frames, a second electromagnet fixed inside the first mounting holes and the second mounting holes, and an assembly rod fixed inside the second electromagnet. The surfaces of the assembly rod and the connecting column are provided with anti-slip layers. The assembly rod is used to assemble the brush head. The housing is provided with a frame driving component.

[0015] As a further optimization of the present invention, the frame drive component includes a third motor fixed to one end of the housing and a bidirectional lead screw fixed to the output end of the third motor. The two sides of the bidirectional lead screw are respectively threaded to two mounting frames. A support rod is fixed in the middle of the front sidewall of the housing. The bidirectional lead screw and the guide rod both pass through the support rod.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) This invention uses a first motor in conjunction with two first pulleys, two second pulleys, and a belt to drive four brush heads to rotate. The inspector can rotate two pressure gauges and simultaneously peel off the PTFE tape from the threaded joints of the two pressure gauges. Before peeling off the PTFE tape using the cleaning device, the inspector can synchronously adjust the height of the two first pulleys and the first tensioning pulley through the position adjustment component to match the height of the cleaning space with the outer diameter of the threaded joint of the pressure gauge. This cleaning device can adapt to pressure gauges of different sizes and can clean the PTFE tape on two pressure gauges at the same time, improving the cleaning effect.

[0018] 2) This invention measures the size of the pressure gauge threaded connector using a size detection component. The cleaning device automatically controls the position adjustment component based on the measurement results. The position adjustment component adjusts the spacing between the brush heads on the upper and lower sides, enabling the cleaning device to adaptively adjust the size of the threaded connector. At the same time, the limit component stops the threaded connector, making it easier for the calibration personnel to control the lateral position of the pressure gauge, thereby improving cleaning efficiency and the convenience of cleaning the PTFE tape.

[0019] 3) The present invention provides a support component on the housing. On the mounting frame of the support component, different columns of mounting rods are equipped with brush heads of different materials, which can replace the brush heads on the cleaning component. When the first electromagnet is de-energized and the second electromagnet is energized, the brush head on the cleaning component is transferred to the corresponding mounting rod. After moving the mounting frame, when the first electromagnet is energized and the second electromagnet is de-energized, the corresponding brush head is assembled onto the connecting column of the cleaning component, thus avoiding damage to the threaded joint of the pressure gauge due to mismatched brush head bristle materials.

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] First Embodiment

[0033] like Figure 1-4As shown, an adaptive pressure gauge thread cleaning device includes a housing 1 and a cleaning assembly 2 disposed inside the housing 1. The cleaning assembly 2 includes two first pulleys 21 disposed on the upper left and right sides of the housing 1 and two second pulleys 22 disposed on the lower left and right sides of the housing 1. Two first tensioning pulleys 23 are disposed between the two first pulleys 21 and two second tensioning pulleys 25 are disposed between the two second pulleys 22. Brush heads 24 are fixedly mounted on the front ends of the first pulleys 21 and the two second pulleys 22. The two first pulleys 21 and the two second pulleys 22 are connected by a belt, and the two first tensioning pulleys 23 and the two second tensioning pulleys 25 abut against the belt. A pulley drive is also disposed inside the housing 1. The pulley drive is a first motor 26 fixed on the bottom wall of the housing 1 by a mounting platform. The output end of the first motor 26 is fixed together with one of the second pulleys 22. Two symmetrical cleaning spaces are formed between the brush heads 24 on the two first pulleys 21 and the brush heads 24 on the two second pulleys 22. The height of the cleaning space is slightly smaller than the outer diameter of the pressure gauge threaded connector. When the threaded connectors of the two pressure gauges are inserted into the cleaning spaces, the four brush heads 24 are in close contact with the two threaded connectors. After the first motor 26 is started, the first motor 26 drives the four brush heads 24 to rotate through the two first pulleys 21, the two second pulleys 22 and the belt. The inspector can rotate the two pressure gauges in his hand by 180 degrees to remove the raw material tape on the threaded connectors of the two pressure gauges at the same time.

[0034] The cleaning component 2 is equipped with a position adjustment component 3 on its rear side. The position adjustment component 3 is used to adjust the height of the first pulley 21 and the first tensioning pulley 23 to control the spacing between the upper and lower brush heads 24. Before using the cleaning device to remove the raw material tape, the inspector first adjusts the height of the two first pulleys 21 through the position adjustment component 3 so that the height of the cleaning space matches the outer diameter of the pressure gauge threaded connector. This allows the cleaning device to adapt to pressure gauges of different sizes and to clean the raw material tape on two pressure gauges at the same time, thus improving the cleaning effect.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the position adjustment assembly 3 includes a mounting bracket 31 fixed inside the housing 1, a first slider 32 slidably disposed in the middle of the mounting bracket 31, and second sliders 33 slidably disposed on both sides of the first slider 32, as shown. Figure 3As shown, the mounting frame 31 consists of a horizontal plate, an inverted L-shaped plate, and three linear guide rails fixed between the horizontal plate and the inverted L-shaped plate. Mounting plates are fixed on both sides of the first slider 32. The first slider 32 is rotatably connected to two first tensioning wheels 23 via the two mounting plates. Two first pulleys 21 are rotatably mounted at the front ends of the two second sliders 33. Two second pulleys 22 and two second tensioning wheels 25 are rotatably mounted at the front end of the inverted L-shaped plate of the mounting frame 31. A first lead screw 34 is rotatably mounted at the center of the front side of the top of the inverted L-shaped plate of the mounting frame 31. The first slider 32 is threaded onto the first lead screw 34. Second lead screws are rotatably mounted on both sides of the top of the inverted L-shaped plate of the mounting frame 31. 35, and the two second lead screws 35 are respectively threadedly connected to the two second sliders 33. The first lead screw 34 is fixedly provided with a first gear 36 on the outside, and the two second lead screws 35 are fixedly provided with a second gear 37 on the outside. The first gear 36 is meshed with a third gear 38 on both sides, and the two third gears 38 are respectively meshed with the two first gears 36. The two third gears 38 are rotatably connected to the top wall of the housing 1 through a rotating shaft. The tops of the first lead screw 34 and the two second lead screws 35 are rotatably located at the top wall of the housing 1. The housing 1 is provided with a gear drive component, which is a second motor 39 fixedly provided at the top of the housing 1, and the output end of the second motor 39 is fixedly provided at the top of the first lead screw 34.

[0036] When the second motor 39 drives the first lead screw 34 to rotate, it can drive the first slider 32 to slide along the guide rail of the mounting bracket 31. The first slider 32 drives the two first tension wheels 23 to move up or down through the mounting plate. At the same time, the first lead screw 34 drives the first gear 36 to rotate. The first gear 36 drives the two second gears 37 to rotate in the same direction through the two third gears 38. Thus, the two second gears 37 drive the two second sliders 33 and the first pulley 21 on the second sliders 33 to move up or down along the guide rail through the second lead screw 35. It should be noted that the ratio of the number of teeth of the first gear 36 to the number of teeth of the second gear 37 is 1 / 2. The belts between the first pulley 21 and the second pulley 22, as well as the belts between the first pulley 21 and the first tensioning wheel 23, are all perpendicular to the horizontal plane. The thread direction of the two second lead screws 35 is the same as that of the first lead screw 34, and the pitch of the two second lead screws 35 is also the same as that of the first lead screw 34. Therefore, the vertical movement of the first pulley 21 is half the vertical movement of the first tensioning wheel 23, which allows the belt to be kept taut through the first tensioning wheel 23 while adjusting the first pulley 21. Additionally, a handle 8 is provided at the top center of the housing 1 to improve the portability of the cleaning device. A rectangular waste tray 9 is movably arranged at the bottom inner side of the housing 1. The rear end of the waste tray 9 fits against the front end of the mounting bracket 31. The outer periphery of the waste tray 9 protrudes upward to form a side wall of the tray body. The inner edge of the side wall of the tray body is chamfered. After the PTFE tape is peeled off, it falls into the waste tray 9. A handle is provided at the right end of the waste tray 9. The waste tray 9 can be pulled out from the inside of the housing 1 by the handle to collect and process the waste PTFE tape. In other embodiments, the third gear 38 can be omitted. In this case, a larger first gear 36 and a second gear 37 are required, but the ratio of the number of teeth of the first gear 36 to the second gear 37 remains unchanged. It should be noted that the thread direction of the two second lead screws 35 should be opposite to that of the first lead screw 34 to ensure that the sliding direction of the second slider 33 is consistent with that of the first slider 32. Furthermore, the third gear 38 can also be replaced by a rack and a corresponding limiting structure.

[0037] Furthermore, such as Figure 5As shown, a size detection component 4 is provided on the housing 1. The size detection component 4 includes a fixed block 41 fixed to the top of the housing 1 and a measuring block 42 abutting against the fixed block 41. A guide member is fixed on the housing 1 and slides with the measuring block 42. A spring 43 is provided between the end of the guide member away from the measuring block 42 and the measuring block 42. A position sensor 44 is provided on the side of the measuring block 42 away from the fixed block 41. The position sensor 44 is a non-contact distance sensor, specifically an ultrasonic sensor, preferably model UB2000-F42-I-V15. The guide member is a slide rail 45 fixed to the top of the housing 1. A connecting rod 46 is fixed to the end of the measuring block 42 away from the fixed block 41. The connecting rod 46 slides inside the slide rail 45. The position sensor 44 is fixed to the end of the slide rail 45 away from the measuring block 42. The top of the ends of the fixed block 41 and the measuring block 42 that abut against each other are both chamfered. The size detection component 4 detects the size of the pressure gauge threaded connector, enabling the cleaning device to drive the position adjustment component 3 to adaptively adjust the spacing between the upper and lower brush heads 24.

[0038] like Figure 10 As shown, a power supply module is provided on the housing 1. The power supply module includes a controller located inside the rear of the housing 1 and a battery module electrically connected to the controller. A switch electrically connected to the controller is located on the top of the housing 1. When the switch is pressed, the cleaning device is powered on. The battery module supplies power to the first motor 26, the second motor 39, and the position sensor 44 through the controller. Both the first motor 26 and the second motor 36 are DC motors. A speed regulator is also provided inside the housing 1. The speed regulator is electrically connected to the controller and the first motor 26. The controller adjusts the speed of the first motor 26 through the speed regulator. A charger electrically connected to the controller is also provided inside the housing 1. After the charger is connected to the power supply, it rectifies the AC power into DC power. The battery module is charged by the controller. The calibrator inserts the threaded connector of the pressure gauge between the fixing block 41 and the measuring block 42. The measuring block 42, which was originally against the fixing block 41, now slides towards the inside of the slide rail 45. The position sensor 44 detects the position information of the measuring block 42 and transmits the collected position information to the controller. The controller calculates the moving distance of the measuring block 42 based on the position information, thereby determining the outer diameter of the threaded connector. Based on the outer diameter of the threaded connector, the controller sends a control command to the position adjustment component 3, causing the output shaft of the second motor 39 to rotate the corresponding number of revolutions, so that the first pulley 21 and the first tensioning pulley 23 move to a height position that matches the size of the threaded connector of the pressure gauge.

[0039] Furthermore, such as Figure 1As shown, two opposing through holes 5 and two limiting components 6 are provided on the front side wall of the housing 1. The through holes 5 are wedge-shaped, with both sides being arc-shaped, having a large-diameter arc surface and a small-diameter arc surface. The bottom position of the small-diameter arc surface of the through hole 5 is aligned with the lower center position of the cleaning space. The limiting component 6 includes an electric push rod 61 fixed to the front end of the housing 1 and a stop plate 62 fixed to the output end of the electric push rod 61. A groove corresponding to the stop plate 62 is provided on the side of the through hole 5 near the limiting component 6. Please refer to [link to relevant documentation]. Figure 3 Two positioning detection components are provided on the front side wall of the housing 1. The two positioning detection components are located at the top of the two through holes 5 respectively. The positioning detection components also use ultrasonic sensors, and their models are the same as those of the position sensor 44. When the pressure gauge threaded connector is inserted into the cleaning space, the lower end of the horizontally placed pressure gauge connector is controlled at the bottom position of the small diameter arc surface of the through hole 5. At this time, the pressure gauge threaded connector can be inserted into the middle position of the cleaning space. The threaded connector can be tightly attached to the upper and lower brush heads 24 to ensure cleaning efficiency. In addition, the controller is electrically connected to the electric push rod 61. While the position adjustment component 3 adjusts the height of the first pulley 21, the controller adjusts the position of the stop plate 62 through the electric push rod 61 so that the distance between the stop plate 62 and the bottom end of the small diameter arc surface of the through hole 5 is consistent with the radius of the threaded connector. When the pressure gauge threaded connector abuts against the stop plate 62, it is exactly in the middle position of the cleaning space to improve cleaning efficiency.

[0040] Second Embodiment

[0041] like Figure 6 , 7 As shown in Figure 9, the difference between this embodiment and the first embodiment is that the housing 1 is also provided with a bearing component 7 for replacing the brush head 24. For different pressure gauges, the material of their threaded connectors may also be different. Common threaded connector materials include steel, stainless steel, cast iron, etc. The material of the brush bristles of the brush head 24 should also match them. The internal structure of the brush head 24 in this embodiment is also different. Specifically, the brush head 24 includes an installation roller 241, an installation groove 242 opened at the rear of the installation roller 241, an assembly hole 243 opened at the front of the installation roller 241, a metal ring 244 fixed at the front of the installation groove 242, and bristles evenly distributed on the surface of the brush head 24. The metal ring 244 is made of ferromagnetic metal. The front ends of the first pulley 21 and the second pulley 22 are both fixed with connecting posts 27 corresponding to the installation groove 242. The connecting posts 27 are provided with a first electromagnet 28 inside.

[0042] Please see Figure 8The support assembly 7 is located in front of the cleaning assembly 2. The support assembly 7 includes a guide rod 71 fixed inside the front of the housing 1, two mounting frames 72 slidably mounted on the guide rod 71, a plurality of first mounting holes 73 opened in the upper part of the mounting frames 72, a plurality of second mounting holes 74 opened in the lower part of the mounting frames 72, a second electromagnet 75 fixed inside the first mounting holes 73 and the second mounting holes 74, and an assembly rod 76 fixed inside the second electromagnet 75. The surfaces of the assembly rod 76 and the connecting post 27 are provided with anti-slip layers. The assembly rod 76 is used to assemble the brush head 24. The housing 1 is provided with a frame driving component. The frame drive unit includes a third motor 77 fixed to one end of the housing 1 and a bidirectional lead screw 78 fixed to the output end of the third motor 77. The third motor 77 is a DC motor. The battery supplies power to the third motor 77 through the controller. The two sides of the bidirectional lead screw 78 are threaded to two mounting frames 72 respectively. The height of the second mounting hole 74 is flush with the height of the second pulley 22. Brush heads 24 with the same bristle material are installed on the mounting rods 76 in the same row behind each mounting frame 72. The bristle material of the brush heads 24 installed on the mounting rods 76 in different rows behind each mounting frame 72 is different.

[0043] like Figure 6 As shown, the top of the housing 1 is equipped with multiple buttons electrically connected to the controller. The buttons are located on one side of the switch, and each button corresponds to a different bristle material. After pressing a button, the controller replaces the brush head 24 on the cleaning assembly 2. Before replacement, the mounting rod 76 on the mounting frame 72 corresponding to the first pulley 21 and the second pulley 22 is empty. The first electromagnet 28 is de-energized, and the second electromagnet 75 is energized. Under the magnetic force of the second electromagnet 75, the metal ring 244 of a set of brush heads 24 on the four connecting posts 27 drives the brush head 24 to move towards the mounting rod 76, so that the mounting roller 241 of the brush head 24 is sleeved on the outside of the mounting rod 76. The mounting rod 76 passes through the mounting hole 2. 43 and metal ring 244, driven by the third motor 77 and the bidirectional lead screw 78, move the two mounting frames 72 along the length of the housing 1, and move the four brush heads 24 that match the pressure gauge threaded connector to the front of the two first pulleys 21 and the two second pulleys 22 respectively. The first electromagnet 28 is energized and the second electromagnet 75 is de-energized. Under the magnetic force of the first electromagnet 28, the metal ring 244 on the brush head 24 drives the brush head 24 to move towards the connecting post 27, so that the mounting roller 241 of the brush head 24 is sleeved on the outside of the connecting post 27, completing the replacement of the brush head 24 and avoiding damage to the pressure gauge threaded connector due to the mismatch of the brush head 24 bristle material.

[0044] Furthermore, such as Figure 8As shown, a support rod 79 is fixed in the middle of the front side wall of the housing 1. The bidirectional lead screw 78 and the guide rod 71 both pass through the support rod 79. The end of the bidirectional lead screw 78 away from the third motor 77 is rotatably connected to the housing 1. The support rod 79 shapes the bidirectional lead screw 78 and the guide rod 71, avoiding significant deformation of the bidirectional lead screw 78 and the guide rod 71, and improving the reliability of the load-bearing component 7.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
