Description

Technical Field

[0001] This invention belongs to the field of steel plate transportation technology, and particularly relates to a magnetic guide device for transporting steel plates. Background Technology

[0002] Marine engineering equipment is the practical foundation for realizing marine resource development and a key focus of marine construction. The manufacturing process of marine equipment requires the processing of a large amount of steel plates, among which the transportation of these plates is a crucial step. However, existing methods of transporting steel plates have several drawbacks: In shipbuilding, marine engineering, and other fields, the transportation and scheduling of steel plates are widespread, with the steel hoisting and loading processes consuming a significant amount of manual labor. Due to the limitations of workshop operating conditions, steel plate transportation typically utilizes equipment such as bridge cranes. The distance between the driver and the work position creates obstacles to observation, making it difficult to guarantee precise steel plate movement. The accuracy of purely manual command cannot be effectively guaranteed. Traditional steel plate guiding devices are mostly ordinary magnetic blocks, which are difficult to separate from the steel plate and are easily damaged and broken, posing significant challenges to the applicability and durability of the devices. At the same time, the fixed attraction force of traditional magnetic blocks cannot be adapted to steel plates of different thicknesses and weights; if the attraction force is too strong, the magnetic block will stick to the steel plate, and if it is too weak, it will easily fall off. Existing guiding devices rely on a single anti-slip structure, which has limited anti-detachment effect, posing safety hazards of device slippage and detachment during hoisting. In addition, traditional technologies rely on manual observation and hand gestures, resulting in large positioning errors and the inability to monitor the device's working status in real time, creating safety blind spots.

[0003] Therefore, there is an urgent need to design a magnetic guide device for transporting steel plates to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetic guide device for transporting steel plates, which enables flexible adjustment of the magnetic attraction strength.

[0005] To achieve the above objectives, the specific technical solution of the steel plate transport magnetic guide device of the present invention is as follows: A magnetic guide device for transporting steel plates includes: a rope clip, an upper magnetic component, a lower magnetic component, a fixed shaft, and a handle; The upper magnetic attraction assembly includes an upper housing, an upper adjusting magnetic sheet, and an upper adjusting unit. The upper adjusting magnetic sheet and the upper adjusting unit are both disposed inside the upper housing. One end of the upper adjusting unit is fixedly connected to the upper adjusting magnetic sheet, and the other end of the upper adjusting unit is fixedly connected to the inner sidewall of the upper housing. The lower magnetic attraction assembly includes a lower housing, a lower adjusting magnetic sheet, and a lower adjusting unit. The lower adjusting magnetic sheet and the lower adjusting unit are both disposed inside the lower housing. One end of the lower adjusting unit is fixedly connected to the lower adjusting magnetic sheet, and the other end of the lower adjusting unit is fixedly connected to the inner sidewall of the lower housing. The upper housing and the lower housing are connected by a fixed shaft; The cable clip is located at the upper end of the upper housing; One end of the handle is fixedly connected to the lower housing, and the other end of the handle is detachably connected to the cable buckle.

[0006] Furthermore, the steel plate transport magnetic guide device also includes a pressure sensor and a controller. The pressure sensor is located inside the lower housing and is electrically connected to the input terminal of the controller. The output terminal of the controller is electrically connected to the upper adjustment unit and the lower adjustment unit.

[0007] Furthermore, the steel plate transport magnetic guide device also includes a wireless transmission unit, and the pressure sensor is signal-connected to the wireless transmission unit.

[0008] Furthermore, the steel plate transport magnetic guide device also includes a laser emitter, which is embedded in the side of the cable buckle, and the emission direction of the laser emitter is consistent with the extension direction of the fixed shaft.

[0009] Furthermore, the steel plate transport magnetic guide device also includes an anti-detachment component, which includes an anti-slip baffle and an anti-slip bushing. The anti-slip baffle is fixedly provided at the lower end of the upper housing and the upper end of the lower housing, and the anti-slip bushing is provided inside the cable buckle.

[0010] Furthermore, both the outer surfaces of the upper and lower housings are provided with horizontal and vertical stripes.

[0011] Furthermore, an upper annular groove is provided at the bottom of the upper housing, and the upper adjusting magnet is nested inside the upper annular groove.

[0012] Furthermore, a lower annular groove is provided on the top of the lower housing, and the lower adjusting magnet is nested inside the lower annular groove.

[0013] Furthermore, the cable clip is provided with a fixing component, which is used to fix the cable.

[0014] Furthermore, the fixing component adopts one or a combination of bolts, buckles, and straps.

[0015] The magnetic guide device for transporting steel plates of the present invention has the following advantages: 1. Flexible magnetic attraction adjustment and wide compatibility: The upper and lower adjustment units drive the adjustment magnetic sheet to move, realizing multi-level adjustment of magnetic attraction strength. It is suitable for steel plates weighing 0.5 to 5 tons and with a thickness of 8 to 50 mm, which expands the compatibility range by 67% compared with traditional magnetic blocks. The adapter and magnetic surface can be replaced, making it suitable for various lifting equipment and flat and non-flat steel plates, with strong versatility. 2. Precise and efficient positioning with reduced operational difficulty: The laser emitter projects a positioning spot, which, combined with manual tensioning and guidance, reduces the positioning error to ±5mm, improving efficiency by 90%~95% compared to traditional manual command; the transportation time for a single steel plate is reduced from 8 minutes to 3 minutes, significantly improving transportation efficiency and reducing reliance on operator experience; 3. Excellent anti-detachment performance and comprehensive safety protection: The anti-detachment component constructs a protection system from the two core contact points of the device and the steel plate, and the device and the rope. Combined with the increased friction from the stripes on the shell surface, it reduces the probability of anti-detachment failure from ≥5% to ≤0.1%. The pressure sensor, controller and wireless transmission unit form a status monitoring system that provides real-time feedback on adsorption pressure and automatically alarms in case of abnormality to avoid sudden safety accidents. 4. Sturdy and durable structure, convenient and labor-saving operation: The upper and lower shells are connected by a double-headed flange short pipe fixed shaft, which has good overall impact resistance and a continuous service life of ≥10,000 times, which is 233% higher than that of traditional magnetic blocks; the device is easy to separate from the steel plate, and only one operator is needed to transport a single steel plate, which reduces the labor input by 50%~67% compared with the traditional method. 5. Strong environmental adaptability and diverse applicable scenarios: In environments ranging from -20℃ to 60℃, the magnetic attraction strength of the device decreases by ≤5%, the laser positioning accuracy remains unbiased, and the wireless transmission module operates normally; Under harsh working conditions where the rust level on the steel plate surface is ≤3mm and the oil stain coverage is ≤10%, the adsorption pressure is still ≥4000N, with no slippage phenomenon, which can meet the needs of various working environments such as workshops and factories.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0020] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes a magnetic guide device for transporting steel plates.

[0021] like Figures 1 to 3 As shown, a magnetic guide device for transporting steel plate 12 includes: a rope buckle 1, an upper magnetic component 2, a lower magnetic component 3, a fixed shaft 4, and a handle 5; The upper magnetic attraction assembly 2 includes an upper housing 21, an upper adjusting magnetic sheet 22, and an upper adjusting unit 23. The upper adjusting magnetic sheet 22 and the upper adjusting unit 23 are both disposed inside the upper housing 21. One end of the upper adjusting unit 23 is fixedly connected to the upper adjusting magnetic sheet 22, and the other end of the upper adjusting unit 23 is fixedly connected to the inner sidewall of the upper housing 21. An upper annular groove is provided at the bottom of the upper housing 21, and the upper adjusting magnetic sheet 22 is nested inside the upper annular groove to ensure that the upper adjusting magnetic sheet 22 is installed firmly and its movement trajectory is accurate. Preferably, both the upper adjusting magnetic sheet 22 and the lower adjusting magnetic sheet 32 ​​are made of neodymium iron boron (N52) material, which has excellent magnetic properties. Driven by the upper adjusting unit 23 and the lower adjusting unit 33, they move axially to change the contact area with the surface of the steel plate 12, thereby realizing multi-level adjustment of the magnetic attraction strength. The adjustment levels include low strength 5000N, medium strength 8000N, and high strength 12000N, which can be adapted to steel plates 12 with a weight of 0.5 to 5 tons and a thickness of 8 to 50 mm. The lower magnetic attraction assembly 3 includes a lower housing 31, a lower adjusting magnetic sheet 32, and a lower adjusting unit 33. The lower adjusting magnetic sheet 32 ​​and the lower adjusting unit 33 are both disposed inside the lower housing 31. One end of the lower adjusting unit 33 is fixedly connected to the lower adjusting magnetic sheet 32, and the other end of the lower adjusting unit 33 is fixedly connected to the inner sidewall of the lower housing 31. A lower annular groove is provided on the top of the lower housing 31, and the lower adjusting magnetic sheet 32 ​​is nested inside the lower annular groove to ensure the installation stability and adjustment reliability of the lower adjusting magnetic sheet 32. The upper housing 21 and the lower housing 31 are connected by a fixed shaft 4, which is a short pipe with a double-ended flange. The fixed shaft 4 serves to securely connect the upper magnetic suction assembly 2 and the lower magnetic suction assembly 3, and also facilitates the separation of the device from the steel plate 12. The cable clip 1 is located at the upper end of the upper housing 21. The cable clip 1 is a circular steel pipe structure. The cable clip 1 is provided with a fixing component 10. The fixing component 10 is used to fix the cable 11. The fixing component 10 adopts one or a combination of bolts, clips, and straps. In this embodiment, the fixing method of bolts and lead screws is preferred. The upper part of the cable clip 1 is provided with threaded holes and bolt holes that are compatible with the fixing component 10 to ensure that the cable 11 is firmly fixed.

[0022] Preferably, the cable clip 1 can be adapted to various lifting equipment such as bridge cranes, gantry cranes, and jib cranes by replacing the adapter connector (such as U-shaped clips or quick connectors). The length of the guide cable 11 can be adjusted within the range of 1 to 10m to meet the different needs of short-distance transportation (3 to 10m) within the workshop and medium-distance transportation (10 to 50m) within the factory area. For non-planar steel plates 12 such as curved steel plates 12 and corrugated steel plates 12, a special curved magnetic surface can be replaced. The radius of curvature of the curved magnetic surface is adapted to 500 to 2000mm. The deformation of the anti-slip edge conforms to the non-planar surface to ensure a firm adsorption. One end of the handle 5 is fixedly connected to the lower housing 31, and the other end of the handle 5 is detachably connected to the cable buckle 1. The handle 5 is made of bent hot-rolled steel plate, which has good structural strength and is convenient for operators to install, disassemble and adjust the position of the device.

[0023] Furthermore, such as Figure 4As shown, the magnetic attraction guide device for transporting the steel plate 12 also includes a pressure sensor 6 and a controller 7. The pressure sensor 6 is located inside the lower housing 31 and is electrically connected to the input terminal of the controller 7. The output terminal of the controller 7 is electrically connected to the upper adjustment unit 23 and the lower adjustment unit 33. The pressure sensor 6 is used to monitor the adsorption pressure between the magnetic attraction component and the steel plate 12 in real time. The controller 7 can automatically adjust the working state of the upper adjustment unit 23 and the lower adjustment unit 33 according to the pressure data, thereby adjusting the magnetic attraction strength and ensuring adsorption stability.

[0024] Furthermore, such as Figure 4 As shown, the steel plate 12 material transfer magnetic attraction guide device also includes a wireless transmission unit 8. The pressure sensor 6 is signal-connected to the wireless transmission unit 8. The wireless transmission unit 8 adopts the Bluetooth 5.0 protocol and can send the pressure data monitored by the pressure sensor 6 to the safety personnel's handheld terminal (such as a smartphone APP) in real time to realize remote monitoring of the adsorption state.

[0025] Furthermore, such as Figure 1 As shown, the steel plate 12 material transport magnetic attraction guide device also includes a laser emitter 9. The laser emitter 9 is embedded in the side of the rope buckle 1. The emission direction of the laser emitter 9 is consistent with the extension direction of the fixed shaft 4. The laser emitter 9 has a power of 5mW and a wavelength of 650nm. It projects a positioning light spot to assist the operator in calibrating the adsorption angle of the device and improves the guidance accuracy.

[0026] Furthermore, the magnetic guide device for transporting the steel plate 12 also includes an anti-detachment component. The anti-detachment component includes an anti-slip edge and an anti-slip bushing. The anti-slip edge is fixedly installed at the lower end of the upper housing 21 and the upper end of the lower housing 31. The anti-slip edge is made of polyurethane elastomer material, with a thickness of 5mm and protruding 3mm from the magnetic surface. Four edges are evenly distributed along the circumference of the housing. It can fit the edge of the steel plate 12 through elastic deformation to form a lateral anti-detachment constraint. The anti-slip bushing is provided inside the cable buckle 1. Preferably, it is a serrated anti-slip bushing. The anti-slip bushing is made of stainless steel, with a serration angle of 30° and a tooth depth of 1mm. It contacts the cable 11 to form a double fixation of mechanical locking and serrated anti-slip, preventing the cable 11 from loosening or slipping.

[0027] Furthermore, the outer surfaces of both the upper housing 21 and the lower housing 31 are provided with horizontal and vertical stripes. The stripes are used to increase the frictional resistance between the device and the surface of the steel plate 12, further preventing the device from slipping.

[0028] The working principle of this application is as follows: The steel plate 12 is fixed in the middle with slings. Based on the thickness and weight of the steel plate 12, the controller 7 presets the adsorption pressure threshold (e.g., adsorption pressure ≥3000N is normal, <3000N is a warning state). The device is placed horizontally 10-20cm from the edge of the steel plate 12. One to two devices are adsorbed onto a single steel plate 12, and multiple devices are used at intervals of 1.5-2m. The device is magnetically attached to the surface of the steel plate 12. The pressure sensor 6 monitors the adsorption pressure in real time and feeds it back to the controller 7. Based on the data from the pressure sensor 6, the controller 7 automatically controls the operation of the upper adjustment unit 23 and the lower adjustment unit 33, adjusting the positions of the upper and lower adjustment magnetic plates 22 and 32 to achieve the appropriate magnetic strength. The guide rope 11 is threaded into the rope clip 1 and secured with bolts. The lead screw is inserted into the opening and the guide rope 11 is fixed with a tightening torque of 30~50 N·m; the laser emitter 9 is turned on, and the adsorption angle is calibrated by the positioning spot projected by the laser beam to ensure accurate guidance direction; the safety personnel establish a connection between the handheld terminal and the wireless transmission unit 8, and after confirming that the adsorption pressure is within the normal range, they stand at a safe distance of ≥3m outside the hoisting area and tighten one side of the guide rope 11; the hoisting equipment (bridge crane, gantry crane, etc.) is started to hoist the steel plate 12, and the safety personnel tension the guide rope with a tension force of 50~100N according to the pressure data fed back by the positioning spot and the handheld terminal to guide the steel plate 12 to move safely and accurately; during transportation, if the adsorption pressure is lower than the warning value, the wireless transmission unit 8 will trigger the audible and visual alarm of the handheld terminal, and the safety personnel will take emergency measures in time.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
