Description

Technical Field

[0001] This utility model relates to the field of hose measurement technology, and in particular to magnetic induction hoses and hose measuring devices. Background Technology

[0002] Hoses are tubular products made of rubber, plastic, or composite materials, possessing excellent flexibility and toughness. They are used in various fields such as industry and chemical processing, primarily serving to transport fluids, protect objects inside the pipe, or connect different equipment.

[0003] Measuring hose length during hose use is crucial for equipment maintenance and cost control. Especially in complex working conditions, accurate length data helps control construction precision and optimize pipeline routing. Currently, hose length is primarily calculated using roller meters, with distances recorded by ink printing, laser engraving, or marking at designated locations. However, roller meters require strict operation, necessitating stable and accurate relative movement between the roller and the hose, which is susceptible to human error in practice. Furthermore, manufacturing tolerances in the roller diameter directly affect measurement accuracy. Therefore, designing a simple and highly accurate hose measuring device and a hose suitable for easy measurement is essential. Utility Model Content

[0004] This invention addresses the shortcomings of low accuracy and complex operation in existing hose measurement technology by providing a magnetic induction hose and a hose measuring device.

[0005] To achieve the above objectives, the present invention provides a hose measuring device, comprising a first mounting bracket, a sensor, at least one second mounting bracket, and a roller component. The sensor is installed inside the first mounting bracket, the second mounting bracket is installed on the first mounting bracket, and the roller component is rotatably connected to the second mounting bracket.

[0006] In one embodiment, the roller component includes a shaft, at least one first limiting plate and at least one second limiting plate, with the first limiting plate fixed to both ends of the shaft, and the second limiting plate installed between the two first limiting plates.

[0007] In one embodiment, the hose measuring device further includes a limiting block, which is movably connected to the second mounting bracket. The limiting block and the second mounting bracket form a mounting hole, and the roller component passes through the mounting hole.

[0008] In one embodiment, there is a receiving space between the second limiting plates for winding a hose.

[0009] In one embodiment, the top of the first mounting bracket has a through hole for a hose to pass through.

[0010] In one embodiment, the first mounting bracket contains a limiting rod, which is mounted above the sensor.

[0011] In one embodiment, the hose measuring device further includes a control system connected to the sensor, the control system being used to receive magnetic field information detected by the sensor.

[0012] This application also provides a magnetic induction flexible tube, including a flexible tube and a plurality of magnets, wherein the flexible tube is mounted on the aforementioned flexible tube measuring device, the magnets are fixed on the flexible tube, and the spacing between any two adjacent magnets is equal.

[0013] In one embodiment, the magnet is disposed along the axial direction of the flexible tube.

[0014] In summary, this invention provides a magnetic induction flexible tube and a tube measuring device. By uniformly fixing the magnet on the surface of the flexible tube and winding the tube around the roller component, the flexible tube will drive the magnet through the through hole and limit it within the sensing area of ​​the sensor by the limiting rod, thus ensuring the effective output of magnetic field change information. This invention can further determine the length of the flexible tube using the obtained number of peaks or peak time. The detection device is characterized by high efficiency and simple operation.

[0027] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Figure 1 This is a schematic diagram of the hose measuring device in this utility model. Figure 1 As shown, the hose measuring device includes a first mounting bracket 1, a sensor 2, at least one second mounting bracket 3, at least one limiting block 4, and a roller component 5. The sensor 2 is installed in the first mounting bracket 1, the second mounting bracket 3 is installed on the first mounting bracket 1, the limiting block 4 is movably connected to the second mounting bracket 3, the limiting block 4 and the second mounting bracket 3 form a mounting hole 6, the roller component 5 passes through the mounting hole 6, and the roller component 5 is installed on the second mounting bracket 3.

[0029] The limiting block 4 is movably mounted on the upper end of the second mounting bracket 3 and can be hinged by a pin to allow the roller component 5 to be installed or removed in the mounting hole 6. Both the limiting block 4 and the second mounting bracket 3 have through holes of matching shape. When the limiting block 4 and the second mounting bracket 3 are assembled, the two through holes will combine to form the mounting hole 6, providing a space to accommodate the roller component 5.

[0030] Combination Figure 1 and Figure 2It is understood that the roller component 5 is used to wind the hose 7, facilitating subsequent access and release of the hose 7. The roller component 5 includes a shaft 51, at least one first limiting plate 52, and at least one second limiting plate 53. The first limiting plates 52 are fixed to both ends of the shaft 51, and the second limiting plates 53 are installed between the two first limiting plates 52. A certain distance is left between the two second limiting plates 53 to provide installation space for winding the hose 7; there is also a certain gap between the first limiting plates 52 and the second limiting plates 53 to facilitate the insertion of the mounting hole 6. The shape of the shaft 51 matches the shape of the mounting hole 6. The cross-section of the shaft 51 can be circular or other shapes that facilitate rolling, while the mounting hole 6 can be circular or other shapes with the same cross-section as the shaft 51. Both the first limiting plate 52 and the second limiting plate 53 can be circular plates, or they can be designed into other shapes according to actual needs. The diameter of the first limiting plate 52 is larger than the diameter of the mounting hole 6, so that the first limiting plate 52 acts as a limit along the axial direction of the shaft 51, preventing the roller component 5 from falling off when rolling. At the same time, the height of the second mounting bracket 3 is greater than the radius of the second limiting plate 53, which can prevent the second limiting plate 53 or the hose 7 from rubbing against the top of the first mounting bracket 1 when rolling, ensuring that the roller component 5 can smoothly release the hose 7.

[0031] like Figure 2 As shown, a plurality of magnets 71 are mounted on the flexible tube 7, and the magnets 71 are arranged along the axial direction of the flexible tube 7, with equal spacing between any two adjacent magnets 71. The magnets 71 may be permanent magnets. During the production process of the flexible tube 7, the magnets 71 can be embedded in the surface of the rough blank before it enters the cooling device. When the rough blank cools and forms the flexible tube 7, the magnets 71 are fixedly connected to the flexible tube 7.

[0032] Combination Figure 1 and Figure 2 It is known that the top end of the first mounting bracket 1 has a through hole 11, which is used to pass through the hose 7.

[0033] Furthermore, the first mounting bracket 1 contains a limiting rod 8, which is installed above the sensor 2. The limiting rod 8 serves a positioning function, ensuring that the path of the flexible tube 7 follows a predetermined trajectory, preventing instability such as deviation or shaking during movement, thus creating favorable conditions for subsequent sensing operations. The flexible tube 7 passes through the through hole 11 and is constrained by the limiting rod 8, and the magnet 71 on the flexible tube 7 also forms a relatively stable path, allowing the magnet 71 to enter the sensing range of the sensor 2. The limiting rod 8 ensures the relative positional relationship between the magnet 71 on the flexible tube 7 and the sensor 2, enabling the sensor 2 to accurately and stably sense the magnet 71, providing crucial assurance for the normal operation of the entire device.

[0034] The sensor 2 is connected to the control system 9. The sensor 2 is used for magnetic field detection, and the control system 9 is used to receive the magnetic field information detected by the sensor 2. The sensor 2 can be a Hall sensor. When the magnet 71 passes by the sensor 2, the magnetic field strength sensed by the sensor 2 will change, and the Hall voltage will also change accordingly. The voltage signal detected by the sensor 2 can be received by the control system 9, and a corresponding voltage spectrum can be output. By using the control system 9 to view the peaks of the voltage spectrum and count the number of peaks, the number of magnets 71 on the hose 7 to be measured can be determined. Since the interval between the magnets 71 is a fixed value, the length of the hose 7 can be further obtained. In addition, by controlling the roller component 5 to move at a uniform speed, the length of the hose 7 can also be determined based on the peak time.

[0035] In summary, this invention provides a magnetic induction flexible tube and a tube measuring device. The magnet 71 is uniformly fixed on the surface of the flexible tube 7, and the flexible tube 7 is wound around the roller component 5. The flexible tube 7 drives the magnet 71 through the through hole 11, and the limiting rod 8 limits it within the sensing area of ​​the sensor 2, ensuring effective output of magnetic field change information. This invention can further determine the length of the flexible tube 7 using the obtained number of peaks or peak time. The detection device is characterized by high efficiency and ease of operation.

Therefore, the scope of protection of the present invention shall be determined by the appended claims.
