Description

Technical Field

[0001] The invention relates to the technical field of hoisting mechanisms, and in particular to magnetic hoisting equipment for flange processing and transportation. Background Art

[0002] In the process of flange processing and transportation, efficient and safe lifting equipment is essential. Although traditional magnetic lifting equipment is widely used due to its convenient operation, it has many disadvantages that are difficult to ignore. First, the existing magnetic suction equipment is prone to slippage when lifting the flange. This is because in actual working conditions, the lifting environment is complex and changeable, such as vibration, tilting, etc., which often occur, resulting in the inability to stably adsorb the flange. Once it slips, it may not only cause damage to the flange, but also pose a serious threat to the safety of surrounding equipment and personnel; secondly, when the magnetic suction equipment contacts the flange, due to the lack of an effective buffering mechanism, collision is likely to occur between the two. This collision will cause damage to the adsorption surface of the flange during long-term and frequent operation, such as scratches, dents, etc.; furthermore, in order to ensure the magnetic suction effect, the adsorption surface of the flange must be carefully cleaned before using the existing magnetic suction equipment, because if there is dust, oil or other impurities on the adsorption surface, it will significantly reduce the adsorption force of the magnetic suction equipment. However, the work of cleaning the adsorption surface is not only tedious and time-consuming, but also requires additional manpower and material resources, which reduces the overall work efficiency.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] In order to ensure the stability of the flange during the lifting and transportation of the flange and improve the reliability and safety during the transportation, as an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, a magnetic lifting equipment for flange processing and transportation described in the present invention includes an electromagnetic adsorption device 1, the upper part of the electromagnetic adsorption device 1 is detachably connected to a conveying mechanism through a lifting component, the outer side of the electromagnetic adsorption device 1 is provided with a clamping component, the lower surface of the electromagnetic adsorption device 1 is provided with an adsorption component, and a buffer component is installed on the electromagnetic adsorption device 1. When the buffer component is squeezed by the flange, it drives the clamping component and the adsorption component to work, and the lower end of the buffer component is provided with a cleaning component for cleaning the flange adsorption surface.

[0018] When in use, start the conveying mechanism, move the electromagnetic adsorption device 1 to a suitable position above the flange to be lifted, slowly lower the electromagnetic adsorption device 1, and when the flange contacts the lower end of the buffer component, turn on the electromagnetic adsorption device 1 to generate magnetic force to adsorb the flange. During the adsorption process between the flange and the electromagnetic adsorption device 1, squeeze the buffer component. The buffer component can avoid scratches, dents and other damages caused by collision between the flange adsorption surface and the electromagnetic adsorption device 1 during adsorption, thereby protecting the surface quality of the flange. At the same time, the buffer structure drives the cleaning component to work when it is squeezed, and the cleaning component is used to clean the flange adsorption surface to remove dust, impurities, etc., in preparation for subsequent adsorption. The buffer component is squeezed to drive the clamping component and the adsorption component to work, and the adsorption component enhances the adsorption effect on the flange; the clamping component clamps the flange from the outside to ensure the stability of the flange during the lifting process; after confirming that the flange is stably adsorbed and clamped, the electromagnetic adsorption device 1 is driven to rise and move to the designated location through the conveying mechanism, so as to ensure the stability of the flange when the flange is lifted and transported, and improve the reliability and safety during transportation.

[0019] In order to effectively reduce the impact force between the flange adsorption surface and the electromagnetic adsorption device 1, for example, Figure 1 , Figure 3 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 As shown, the present invention also includes that the buffer assembly includes a piston cylinder 2 vertically connected to the upper surface of the electromagnetic adsorption device 1, the two ends of the piston cylinder 2 are closed, a vertically arranged piston rod 3 is provided in the piston cylinder 2, the upper and lower ends of the piston rod 3 pass through the piston cylinder 2 and are sealed and slidably connected to the piston cylinder 2, a piston plate 4 slidably connected to the piston cylinder 2 is fixedly installed on the piston rod 3, a through-set slide groove 5 is provided in the middle part of the electromagnetic adsorption device 1, the lower end of the piston rod 3 passes through the slide groove 5 and is slidably connected to the slide groove 5, and a first spring 6 is fixedly connected between the side of the piston plate 4 away from the electromagnetic adsorption device 1 and the inner wall of the piston cylinder 2.

[0020] When in use, start the conveying mechanism, move the electromagnetic adsorption device 1 to a suitable position directly above the flange to be lifted, turn on the electromagnetic adsorption device 1 to generate magnetic force, and as the electromagnetic adsorption device 1 approaches the flange and starts to adsorb, the flange is attracted by the magnetic force and moves upward to the electromagnetic adsorption device 1, and the flange contacts and squeezes the lower end of the piston rod 3. After the piston rod 3 is squeezed, it slides upward along the slide groove 5 in the middle of the electromagnetic adsorption device 1, and the piston rod 3 drives the piston plate 4 to move upward synchronously in the piston cylinder 2. The first spring 6 between the side of the piston plate 4 away from the electromagnetic adsorption device 1 and the inner wall of the piston cylinder 2 is squeezed and compressed by the piston plate 4. The elastic deformation of the first spring 6 generates a reverse force, which plays a buffering role, effectively reducing the impact force between the flange adsorption surface and the electromagnetic adsorption device 1, and protecting the surface quality of the flange.

[0021] In order to facilitate the cleaning of the adsorption surface of the flange, for example, Figure 3 , Figure 7 , Figure 8 , Fig.10 , Fig.11As shown, the present invention also includes that the cleaning component includes a cavity 7 arranged in the piston rod 3, the lower end surface of the piston rod 3 is provided with a first air outlet 9 connected to the cavity 7, the lower side surface of the piston rod 3 is connected to a plurality of groups of circumferentially distributed second air outlet holes 10, the upper part of the piston rod 3 near the upper surface of the piston plate 4 is provided with an air vent 11 connected to the cavity 7, a sealing ring 31 is slidably connected in the cavity 7, the lower part of the sealing ring 31 is connected to a positioning slide rod 32, a second spring 33 is sleeved on the positioning slide rod 32, the lower end of the positioning slide rod 32 passes through the lower end of the piston rod 3 and is connected to the elastic block 8, and the second air outlet 10 is opened after the sealing ring 31 moves up.

[0022] When in use, during the process of the electromagnetic adsorption device 1 adsorbing the flange, the flange is attracted by the magnetic force and moves upward and gradually approaches the electromagnetic adsorption device 1. When the flange and the electromagnetic adsorption device 1 are close, they are first squeezed to the lower end of the positioning slide rod 32. While the positioning slide rod 32 moves in the cavity 7, it also drives the piston rod 3 to move upward. The piston plate 4 also moves upward in the piston cylinder 2. The air in the piston cylinder 2 is squeezed, and the squeezed air enters the cavity 7 in the piston rod 3 through the vent hole 11. Since the flange squeezes the lower end of the positioning slide rod 32 in the early stage, the second air outlet 10 is blocked by the sealing ring 31, and the air entering the cavity 7 is only The air discharged from the first air outlet 9 directly impacts the middle of the flange adsorption surface, blowing the dust and impurities on the surface to the edge of the flange; as the distance between the flange and the electromagnetic adsorption device 1 gets closer, the positioning slide bar 32 is squeezed and completely moves upward, thereby driving the sealing ring 31 to move upward and open the second air outlet 10, and because the flange and the lower end surface of the piston rod 3 are in contact, the air output of the first air outlet 9 will be greatly reduced; at this time, the air discharged from the second air outlet 10 further cleans the dust and impurities moved to the edge of the flange, realizing sequential cleaning from the middle of the flange to the edge, ensuring that the entire adsorption surface can be effectively cleaned; During the cleaning process, the elastic block 8 fixedly connected to the lower surface of the piston rod 3 can buffer the impact force between the piston rod 3 and the flange, preventing the hard collision between the two from causing damage to the flange and the end surface of the positioning slide rod 32.

[0023] In order to ensure that the flange is stably adsorbed during the lifting process, for example, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9As shown, the present invention also includes that the adsorption component includes a plurality of groups of conical grooves 12 which are circumferentially distributed on the lower surface of the electromagnetic adsorption device 1 and are smaller at the top and larger at the bottom, a suction cup 13 is provided in the conical groove 12, and a through hole 14 connected to the conical groove 12 is provided on the upper surface of the electromagnetic adsorption device 1, and a plurality of groups of connecting tubes 15 corresponding to the through hole 14 are detachably connected to the outer side of the piston cylinder 2, one end of the connecting tube 15 is connected to the through hole 14, and the end of the connecting tube 15 away from the through hole 14 is connected to the lower part of the piston cylinder 2.

[0024] When in use, during the process of the electromagnetic adsorption device 1 adsorbing the flange, the flange squeezes the piston rod 3 of the buffer assembly, and the piston rod 3 is squeezed upward, driving the piston plate 4 to move upward in the piston cylinder 2, so that the air pressure in the lower space of the piston cylinder 2 is reduced, thereby increasing the adsorption force of the suction cup 13 in the tapered groove 12. The suction cup 13 fits tightly with the flange surface, and the tapered groove 12 structure with a small top and a large bottom helps to enhance the adsorption effect between the suction cup 13 and the flange, ensuring that the flange is stably adsorbed during the lifting process and is not easy to fall off; After the flange is lifted to the specified position, the electromagnetic adsorption device 1 is closed, the piston rod 3 descends, and the piston plate 4 moves downward; the downward movement of the piston plate 4 increases the air pressure in the lower space of the piston cylinder 2, and the suction cup 13 no longer adsorbs the flange, thereby facilitating the separation of the flange and the electromagnetic adsorption device 1.

[0025] In order to further fix the flange from the outside, for example, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 As shown, the present invention also includes that the clamping assembly includes a movable plate 16 fixedly connected to the upper end of the piston rod 3 and arranged horizontally, the edge of the electromagnetic adsorption device 1 is provided with a plurality of groups of circumferentially distributed first grooves 17, and the movable plate 16 is provided with a plurality of groups of second grooves 18 corresponding to the first grooves 17, the second grooves 18 are located at the edge of the upper surface of the movable plate 16, and the first grooves 17 and the second grooves 18 are both arranged to penetrate from top to bottom; The first groove 17 is provided with a mechanical clamp 19, and the mechanical clamp 19 is rotatably connected to the inner wall of the first groove 17 through a rotating shaft 20. The end of the mechanical clamp 19 away from the electromagnetic adsorption device 1 is provided with a waist-shaped hole 21, and the inner wall of the second groove 18 is fixedly connected with a horizontally arranged extrusion rod 22, and the extrusion rod 22 passes through the waist-shaped hole 21.

[0026] When in use, when the electromagnetic adsorption device 1 adsorbs the flange to squeeze the piston rod 3 and moves upward, the piston rod 3 drives the moving plate 16 to rise synchronously. As the moving plate 16 rises, the extrusion rod 22 fixedly connected in the second groove 18 on the moving plate 16 also rises. During the rising process of the extrusion rod 22, the mechanical clamp 19 is pushed to rotate around the rotating shaft 20 in the first groove 17. The mechanical clamp 19 gradually approaches the edge of the flange and clamps it, fixing the flange from the outside to prevent the flange from slipping during the lifting process. After confirming that the mechanical clamp 19 firmly clamps the flange, the lifting work is carried out. After the lifting is completed and reaches the specified position, the electromagnetic adsorption device 1 is closed, the piston rod 3 descends, and the movable plate 16 is driven to descend. At this time, the extrusion rod 22 descends with the movable plate 16, and the mechanical clamp 19 releases the flange with the cooperation of the waist hole 21 and the extrusion rod 22, thereby completing the lifting and transportation of the flange.

[0027] For example, Figure 1 , Figure 2 As shown, the present invention also includes that the lifting assembly includes a plurality of groups of circumferentially distributed connection seats 23 detachably connected to the upper surface of the electromagnetic adsorption device 1, and the connection seats 23 are fixedly connected with lifting ropes 24. A lifting seat 25 is provided above the electromagnetic adsorption device 1, and the ends of the lifting ropes 24 away from the connection seats 23 are fixedly connected to the lower surface of the lifting seat 25, and the upper surface of the lifting seat 25 is fixedly connected with a lifting ring 26.

[0028] When in use, one end of the lifting rope 24 is fixedly connected to the connecting seat 23 to ensure a stable connection; then the other end of the lifting rope 24 away from the connecting seat 23 is connected to the corresponding lower surface of the lifting seat 25, so that the lifting rope 24 is evenly distributed and tightly fixed on the lower surface of the lifting seat 25, and the lifting ring 26 on the upper surface of the lifting seat 25 is connected to the conveying mechanism, and then the conveying mechanism is started, and the lifting ring 26 and the lifting seat 25 are controlled to rise or fall through the conveying mechanism, thereby driving the lifting rope 24, the connecting seat 23 and the electromagnetic adsorption device 1 to lift the flange and transport the flange to the designated position.

[0029] Exemplarily, as shown in FIG2 , the present invention further includes that the conveying mechanism includes a gantry 27 , an electric hoist 28 is provided on the gantry 27 , and the lifting ring 26 is detachably connected to the electric hoist 28 by a buckle.

[0030] When in use, align the lifting ring 26 with the buckle of the electric hoist 28, put the lifting ring 26 into the buckle, ensure that the lifting ring 26 is in full contact with the buckle, and then operate the buckle to close it, completing the detachable connection between the lifting ring 26 and the buckle of the electric hoist 28, and rely on the electric hoist 28 to drive the lifting ring 26, the lifting assembly, and the magnetic lifting equipment and flange below to rise slowly. When the flange rises to a suitable height, rely on the electric hoist 28 to move along the track of the gantry 27 to lift the flange to the designated location, thereby completing the lifting operation of the flange.

[0031] For example, 3. Figure 4 As shown, the present invention also includes that a replaceable anti-skid pad 29 is provided on the surface of the mechanical clamp 19 , and the anti-skid pad 29 is made of polyurethane material; a self-lubricating bearing 30 is connected between the rotating shaft 20 and the inner wall of the first groove 17 .

[0032] When in use, when the electromagnetic adsorption device 1 adsorbs the flange to squeeze the piston rod 3 and drives the movable plate 16 to rise, the squeezing rod 22 on the movable plate 16 pushes the mechanical clamp 19 to rotate around the rotating shaft 20. Since a self-lubricating bearing 30 is connected between the rotating shaft 20 and the inner wall of the first groove 17, the self-lubricating bearing 30 can reduce the friction force when the mechanical clamp 19 rotates, so that the mechanical clamp 19 can smoothly rotate around the rotating shaft 20 in the first groove 17, thereby stably clamping the flange; During the clamping process, the anti-skid pad 29 on the surface of the mechanical clamp 19 contacts the surface of the flange. The anti-skid pad 29 made of polyurethane material increases the friction force to prevent the flange from slipping out of the mechanical clamp 19 during the lifting process.

[0033] When the present invention is in use, one end of the lifting rope 24 is fixed to the connection seat 23 on the upper surface of the electromagnetic adsorption device 1, and the other end is connected to the lower surface of the lifting seat 25, so that the lifting rope 24 is evenly distributed and firmly connected; the lifting ring 26 on the upper surface of the lifting seat 25 is connected to the buckle of the electric hoist 28 on the gantry 27, and the electric hoist 28 is started to control the whole equipment to move to a suitable position just above the flange to be lifted; The electromagnetic adsorption device 1 is turned on to generate magnetic force. As the electromagnetic adsorption device 1 approaches the flange and starts to adsorb, the flange is attracted by the magnetic force and moves upward to the electromagnetic adsorption device 1. In this process, the flange contacts and squeezes the lower end of the piston rod 3. After the piston rod 3 is squeezed, it slides upward along the slide groove 5 in the middle of the electromagnetic adsorption device 1. The piston rod 3 drives the fixedly installed piston plate 4 to move upward synchronously in the piston cylinder 2. The first spring 6 between the side of the piston plate 4 away from the electromagnetic adsorption device 1 and the inner wall of the piston cylinder 2 is squeezed and compressed by the piston plate 4. The elastic deformation of the first spring 6 generates a reverse force, which plays a buffering role, effectively reducing the impact force between the flange adsorption surface and the electromagnetic adsorption device 1, and protecting the surface quality of the flange. During the process of the electromagnetic adsorption device 1 adsorbing the flange, the flange is attracted by the magnetic force and moves upward and gradually approaches the electromagnetic adsorption device 1. When the flange and the electromagnetic adsorption device 1 are close, they are first squeezed to the lower end of the positioning slide rod 32. While the positioning slide rod 32 moves in the cavity 7, it also drives the piston rod 3 to move upward. The piston plate 4 also moves upward in the piston cylinder 2. The air in the piston cylinder 2 is squeezed, and the squeezed air enters the cavity 7 in the piston rod 3 through the vent hole 11. Due to the initial stage of the flange squeezing the lower end of the positioning slide rod 32, the second air outlet 10 is blocked by the sealing ring 31, and the air entering the cavity 7 can only come from The air discharged from the first air outlet 9 directly impacts the middle of the flange adsorption surface, blowing the dust and impurities on the surface to the edge of the flange; as the distance between the flange and the electromagnetic adsorption device 1 gets closer, the positioning slide bar 32 is squeezed and completely moves upward, thereby driving the sealing ring 31 to move upward and open the second air outlet 10, and because the flange and the lower end surface of the piston rod 3 are in contact, the air discharge of the first air outlet 9 will be greatly reduced; at this time, the air discharged from the second air outlet 10 further cleans the dust and impurities moved to the edge of the flange, realizing sequential cleaning from the middle of the flange to the edge, ensuring that the entire adsorption surface can be effectively cleaned; During the cleaning process, the first spring 6 and the elastic block 8 connected to the lower end of the positioning slide rod 32 can buffer the impact force between the piston rod 3 and the flange to prevent the hard collision between the two from causing damage to the flange surface; As the electromagnetic adsorption device 1 is adsorbed on the flange, the buffer component is continuously squeezed, driving the piston plate 4 to move upward in the piston cylinder 2, causing the air pressure in the lower space of the piston cylinder 2 to change. When the air pressure in the lower space of the piston cylinder 2 is reduced, the adsorption force of the suction cup 13 in the conical groove 12 is increased, and the suction cup 13 fits tightly with the flange surface. The conical groove 12 structure with a small top and a large bottom helps to enhance the adsorption effect between the suction cup 13 and the flange, ensuring that the flange is stably adsorbed during the lifting process and is not easy to fall off; When the electromagnetic adsorption device 1 adsorbs the flange to squeeze the piston rod 3 to move upward, the piston rod 3 drives the moving plate 16 to rise synchronously. As the moving plate 16 rises, the extrusion rod 22 fixedly connected in the second groove 18 on the moving plate 16 also rises. During the rising process of the extrusion rod 22, the mechanical clamp 19 is pushed to rotate around the rotating shaft 20 in the first groove 17. The mechanical clamp 19 gradually approaches the edge of the flange and clamps it, fixing the flange from the outside to prevent the flange from slipping during the lifting process. After confirming that the mechanical clamp 19 firmly clamps the flange, operate the electric hoist 28 to drive the lifting ring 26, the lifting assembly, the magnetic lifting equipment below and the flange to rise slowly. After rising to a suitable height, move along the gantry 27 track to lift the flange to the designated location; after reaching the designated location, turn off the electromagnetic adsorption device 1, the piston rod 3 descends to drive the moving plate 16 to descend, and the extrusion rod 22 moves down accordingly. The mechanical clamp 19 releases the flange with the cooperation of the waist hole 21 and the extrusion rod 22, and the piston rod 3 descends to drive the piston plate 4 to move down. The downward movement of the piston plate 4 restores the air pressure in the lower space of the piston cylinder 2 to normal, which is transmitted through the connecting pipe 15, and the pressure difference in the conical groove 12 disappears, and the suction cup 13 no longer adsorbs the flange, completing the lifting and transportation work.
