In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0031] Please refer to Figures 1 to 3A preferred embodiment of the utility model provides a double-cylinder driven lifting iron remover, which mainly includes a bracket 10, a support rod 20, a driving cylinder 30, a first hanging bar 40, a second hanging bar 50 and an iron remover body 60.
[0032] like Figures 1 to 3 As shown, the bracket 10 serves as the supporting structure of the entire double-cylinder driven lifting iron remover. In this preferred embodiment, the bracket 10 includes two bracket units arranged opposite to each other. The two bracket units have the same structure. The bracket units arranged opposite to each other include bracket legs 11 located at both ends, and a bracket beam 12 is arranged between the bracket legs 11 located at both ends. The bracket legs 11 located at both ends may have different heights and different inclination angles. For example, in this preferred exemplary embodiment, the bracket leg 11 located at one end is short and has a small inclination, and the bracket leg 11 located at the other end is long and has a large inclination. At this time, a bracket beam 12 is arranged between the bracket legs 11 located at both ends and is arranged in an inclined manner. Preferably, the bracket legs 11 and the bracket beam 12 are integrally stamped and formed. In other preferred embodiments, the bracket legs 11 and the bracket beam 12 may also be fixed to each other by welding or the like. A cross bar 13 is arranged between the bracket legs 11 of the two bracket units. The cross bar 13 can enhance the structural stability of the bracket 10. The cross bar 13 can be a round bar structure or an I-beam structure. It can be fixedly installed on the bracket leg 11 by welding or the like, or it can be detachably installed on the bracket leg 11 by bolt connection or the like.
[0033] There are two support rods 20, which are transversely arranged on the bracket 10, specifically, the two ends are bolted to the bracket beam 12, and the two support rods 20 are transversely arranged and parallel to each other. In this exemplary embodiment, since the bracket beam 12 is inclined, the two support rods 20 are at different heights, specifically, the support rod 20 away from the driving cylinder 30 is higher.
[0034] There are two drive cylinders 30 to realize a dual-cylinder drive form, and the two drive cylinders 30 operate simultaneously. The drive cylinder 30 extends longitudinally, and the end of the drive cylinder 30 is rotatably connected to the bracket 10, specifically, the end of the drive cylinder 30 is rotatably mounted on the cross bar 13, and the rotation direction is upward or downward rotation around the rotation point. The drive cylinder 30 preferably adopts one of an oil cylinder, an air cylinder or an electric cylinder. In this exemplary embodiment, the drive cylinder 30 uses a hydraulic cylinder and adopts a dual hydraulic cylinder drive control form. By adopting a hydraulic system, precise control, fuel saving and environmental protection are achieved, and the control method is achieved through a hydraulic cylinder operating valve, that is, the hydraulic cylinder can be operated to achieve lifting and lowering, and the operation is flexible and convenient. At the same time, the maintenance of the hydraulic cylinder is more convenient, and it no longer costs manpower to adjust the height of the iron remover body 60 on the machine.
[0035] The first suspension bar 40 and the second suspension bar 50 are chains or ropes, or other flexible pulling objects. The first suspension bar 40 and the second suspension bar 50 should have a certain strength to bear the weight of the iron remover body 60 without breaking to avoid the iron remover body 60 falling. In this preferred embodiment, the first suspension bar 40 and the second suspension bar 50 are O-shaped chains.
[0036] One end of the first suspension bar 40 goes around a support rod 20 away from the drive cylinder 30 and then goes down, and the other end goes around another support rod 20 close to the drive cylinder 30 and then goes down, and the middle part of the first suspension bar 40 is connected to the front end of one of the drive cylinders 30. For example, in an exemplary embodiment, the end (main body) of one of the drive cylinders 30, which is a hydraulic cylinder, is rotatably connected to the bracket 10, and the front end (telescopic rod) is connected to the middle part of the first suspension bar 40. It should be understood that in the present invention, the middle part connection of the first suspension bar 40 is not limited to the middlemost part of the first suspension bar 40 or the part close to the middlemost part, and the middle part of the first suspension bar 40 can be other parts except the two ends.
[0037] One end of the second suspension bar 50 goes around a support rod 20 away from the drive cylinder 30 and then goes down, and the other end goes around another support rod 20 close to the drive cylinder 30 and then goes down, and the middle of the second suspension bar 50 is connected to the front end of one of the drive cylinders 30. For example, in an exemplary embodiment, the end (main body) of one of the drive cylinders 30, which is a hydraulic cylinder, is rotatably connected to the bracket 10, and the front end (telescopic rod) is connected to the middle of the second suspension bar 50. It should be understood that in the present invention, the middle connection of the second suspension bar 50 is not limited to the middlemost part of the first suspension bar 40 or the part close to the middlemost part, and the middle of the second suspension bar 50 can be other parts except the two ends.
[0038] In the utility model, the first suspension bar 40 is connected to a driving cylinder 30, and the second suspension bar 50 is connected to a driving cylinder 30. The first suspension bar 40 and the second suspension bar 50 are controlled by double-cylinder driving to realize a double-cylinder driven lifting iron remover.
[0039] The iron remover body 60 removes ferromagnetic impurities mixed in the material by generating a strong magnetic field attraction, that is, the iron remover body 60 removes iron by magnetic attraction, usually in the form of an electromagnet. The iron remover body 60 is connected to the two ends of the first suspension bar 40 and the second suspension bar 50, and is hung at a certain position and height by the pulling of the first suspension bar 40 and the second suspension bar 50. In this exemplary embodiment, the iron remover body 60 is a rectangular parallelepiped structure as a whole, and is arranged horizontally as a whole. The first suspension bar 40 and the second suspension bar 50 have four ends in total, and are respectively connected to the two sides of the two ends of the iron remover body 60.
[0040] During implementation, the iron remover body 60 is suspended at a certain position and height by the pulling of the first hanging bar 40 and the second hanging bar 50. When the height of the iron remover body 60 needs to be adjusted, when the driving cylinder 30 is retracted, the two ends of the first hanging bar 40 and the second hanging bar 50 are pulled upward, and the iron remover body 60 rises accordingly. When the driving cylinder 30 is extended, the two ends of the first hanging bar 40 and the second hanging bar 50 are driven downward, and the iron remover body 60 drops accordingly. Thus, the lifting and lowering of the iron remover body 60 is realized by the extension and retraction of the two driving cylinders 30. This method is flexible in operation. The driving method of the driving cylinder 30 does not require manpower to personally pull the iron remover, which consumes little manpower and material resources, has low maintenance costs, and is simple and easy to operate. The dual-cylinder driven lifting iron remover of the utility model is flexible and convenient to operate, and is easy to maintain. It can be widely used in various types of iron removers through the automatic lifting method of the new iron remover.
[0041] Taking into account that the conveyor belts for conveying materials are not all horizontal, they can also be set at an angle. Based on this, on the one hand, the height of the connection point with the iron remover body 60 can be adjusted by adjusting the length of the end of the first suspension bar 40 and the second suspension bar 50 connected to the iron remover body 60 to adjust the inclination of the iron remover body 60 to a certain angle. On the other hand, the inclination of the iron remover body 60 can also be adjusted to a certain angle by adjusting the position where the drive cylinder 30 is connected to the middle of the first suspension bar 40 and the second suspension bar 50.
[0042] The front end of the driving cylinder 30 is provided with a hanging ring 31, and the first hanging bar 40 and the second hanging bar 50 pass through the hanging ring 31 respectively. During implementation, the front ends of the two driving cylinders 30 are respectively provided with a hanging ring 31, the first hanging bar 40 passes through the hanging ring 31 at the front end of the driving cylinder 30 on the same side, and the second hanging bar 50 passes through the hanging ring 31 at the front end of the driving cylinder 30 on the same side. At this time, the first hanging bar 40 and the second hanging bar 50 can move in the hanging ring 31, so as to adjust the position of the first hanging bar 40 and the second hanging bar 50 acting on the hanging ring 31, so as to adjust the position where the first hanging bar 40 and the second hanging bar 50 contact the hanging ring 31 as a dividing line, and the length of the hanging bars on both sides, so as to adjust the inclination angle of the iron remover body 60. The first hanging bar 40 and the second hanging bar 50 pass through the hanging ring 31 respectively, and the two end parts respectively bypass the support rod.
[0043] The first suspension bar 40 and the second suspension bar 50 of the chain are inserted with a limit pin 41 at the part passing through the hanging ring 31, and the limit pin 41 is located below the hanging ring 31. In other preferred embodiments, the limit pin 41 can also be located below and below the hanging ring 31. The iron remover body 60 has a certain weight. Under the pull of the first suspension bar 40 and the second suspension bar 50, it can generally maintain an unchanged angle under its own weight and the action of the hanging ring 31 and the first suspension bar 40 and the second suspension bar 50. However, sometimes when the double-cylinder driven lifting iron remover and its supporting device move, causing the double-cylinder driven lifting iron remover to shake or the iron remover body 60 of the double-cylinder driven lifting iron remover to contact the outside, the angle of the iron remover body 60 may change. At this time, by inserting the limit pin 41 into the part of the first hanging bar 40 and the second hanging bar 50 that passes through the hanging ring 31, the limit pin 41 cannot pass through the hanging ring 31, and the first hanging bar 40 and the second hanging bar 50 can be limited to not move in the hanging ring 31, thereby maintaining the angle of the iron remover body 60. When the angle of the iron remover body 60 needs to be adjusted, the first hanging bar 40 and the second hanging bar 50 can be adjusted by removing the limit pin 41.
[0044] Preferably, a connecting seat 32 is provided on the hanging ring 31, and the connecting seat 32 is rotatably connected to the front end of the driving cylinder 30. By providing the connecting seat 32 and the rotatably connected relationship, the pulling on the end of the driving cylinder 30 can be better adapted to during the extension and retraction process of the driving cylinder 30.
[0045] The first suspension bar 40 and the second suspension bar 50 are hung on the support rod 20. When the iron remover body 60 is lifted or moved, the first suspension bar 40 and the second suspension bar 50 may axially deflect on the support rod 20, affecting the normal use of the iron remover body 60. In a preferred embodiment, two turntables 21 are installed on each support rod 20, and the turntable 21 is coaxially rotatably installed on the support rod 20. The turntable 21 can only rotate on the support rod 20 but cannot move axially. The first suspension bar 40 and the second suspension bar 50 bypass the turntable 21. Then, by setting the turntable 21, it can be ensured that the first suspension bar 40 and the second suspension bar 50 can only be pulled at one position on the support rod 20 without axial deviation. At the same time, setting the turntable 21 can also reduce the friction between the first suspension bar 40 and the second suspension bar 50 and the support rod 20, that is, the sliding friction between the first suspension bar 40 and the second suspension bar 50 and the support rod 20 is converted into the rolling friction between the support rod 20 and the turntable 21, so that the first suspension bar 40 and the second suspension bar 50 can be pulled more smoothly, and the first suspension bar 40 and the second suspension bar 50 can also be protected to avoid damage and breakage that affect use. The turntable 21 is installed at both ends of the support rod 20, which is located just above the connection point between the ends of the first suspension bar 40 and the second suspension bar 50 and the iron remover body 60, so that the iron remover body 60 can be lifted and lowered more smoothly.
[0046] In this preferred embodiment, the lower ends of the bracket legs 11 of the bracket 10 are fixedly mounted on the external supporting structure, and the bracket 10 is not movable.
[0047] In some other preferred embodiments, the support legs 11 at one end of the two support units of the support 10 are rotatably connected to the outside, and the support legs 11 at the other ends of the two support units are provided with a driving member for driving the support units to rotate up and down. The support legs 11 can be rotatably connected to the outside through a structure such as a hinge support, and the driving member for driving the support legs 11 at the other end can be a hydraulic cylinder or a cylinder, etc., which is used to drive the support 10 to rotate around one end, so that the position and tilt angle of the iron remover body 60 thereon can be adjusted.
[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
