Description

Electrolytic aluminum anode repairing turn-over disc lifting machine

Technical Field

The utility model relates to a mechanical device, in particular to an electrolytic aluminum anode repairing turnover lifting machine.

Background

The anode is a device used in the production process of electrolytic aluminum, and is mostly composed of carbon blocks, also called anode blocks, steel claws and conductive rods. The carbon block is easily broken during use, and thus requires frequent repair. The main repair modes at present are: the broken residue is taken out of the electrolytic cell and sent to a repair shop. The repair workshop is provided with a residual block repair assembly line, and a plurality of sets of lifting appliances capable of sliding and walking are arranged above the assembly line. The sling is hung with a pair of hanging sleeves which can be spliced with the anode conducting rod through a cable. The anode block conducting rod of the defective product is inserted into the hanging sleeve and sent into the repairing assembly line. And hanging the repaired finished anode block on a hanging sleeve, and then separating the finished anode block from the hanging sleeve. Therefore, the assembly and disassembly of the anode block conducting rod and the lifting appliance are the conventional operation of an anode repair workshop. Heretofore, the handling operation has been often performed by a forklift. However, the difficulty of loading and unloading is high due to the heavy weight of the anode block. When the forklift is used for operation, the position of the conducting rod on the anode block is difficult to be accurately opposite to the hanging sleeve, the swinging amplitude of the hanging sleeve is large during insertion, and the stress of each cable chain is uneven. Particularly, when the insertion is completed, the supporting arm of the forklift needs to be withdrawn along the horizontal direction, and is easy to scrape with the anode block so as to aggravate swinging, so that the failure of cable breakage frequently occurs, and the loading and unloading efficiency of the anode block is seriously affected. To solve this problem, developed countries use a liftable platform, under which a parallel four bar mechanism is supported, which is operated to lift by hydraulic cylinders. The platform is arranged below the hanging sleeve of the lifting appliance, and the anode is assembled or disassembled through lifting. The platform is accurate in position, stable in lifting and difficult to damage, so that the lifting appliance is cited by a plurality of domestic enterprises. However, this device suffers from a new problem during use. Because the anode scrap block has loose structure, the fallen impurities are many, and because the platform can not be turned over, the cleaning of the impurities is laborious and time-consuming, the occupied time of the station is long, and the running operation is hindered. Therefore, some manufacturers add wheels to the lifting platform, and pull the platform away after one-time assembly is completed, and push the platform back after cleaning. Therefore, the assembly is carried out once and once, the continuity of platform operation is seriously affected, the operation efficiency is low, and the requirement of line operation is hardly met.

First embodiment: fig. 1, 2 and 3 illustrate an electrolytic aluminum anode repairing tray lift. As can be seen, the frame of the lift is a three-dimensional frame 2 consisting of a plurality of uprights 1. Four columns are illustrated in the figure, and a cubic framework is formed by connecting the bottom plate and the cross balance. The inner side of each upright post of the frame is provided with an upright slideway 9, and a lifting table 4 which can be driven by a power device to lift along the slideway is arranged in the frame. The lifting platform is a rectangular platform, and the power device is a hydraulic cylinder 3. There are also various ways of installing the hydraulic cylinder, four hydraulic cylinders are illustrated in the figure, and are respectively installed at the upper parts of the four slide ways. The piston rod 10 of the hydraulic oil cylinder is arranged in the slideway 9, and four corners of the lifting platform are connected with the piston rod 10 in the slideway through the sliding block 11. The lifting platform is provided with a supporting arm 5, and the supporting arm has a plurality of structural forms, can be two steel beams and is arranged on the lifting platform. Two cantilever arms can also be extended forwards from two sides of the front edge of the lifting platform as shown in the figure. The support arm extends out of the frame and supports a flat pallet 6 via a pallet shaft 8 and a lock 7. The pallet shaft can be fixed on two sides of the pallet and is connected with the supporting arm in a rotating way. Or can be fixed on the inner side of the supporting arm and is rotationally connected with the supporting plate. The pallet shaft is preferably located where the pallet is adjacent to the upright. The form of the lock here is also numerous: a simple plug is illustrated. The inserting shaft is inserted through the shaft hole of the supporting arm and is rotationally connected with the two sides of the supporting plate. The inserting shaft is inserted, and the supporting plate can be fixed in a flat position together with the supporting plate shaft 8 at one end of the supporting plate. Thus, the anode block group can be placed on the supporting plate and then ascend along with the lifting table. As can be seen from fig. 4, the anode blocks 12 on the pallet are arranged in groups, a plurality of steel claws 13 are fixed on the anode blocks, and upright conductive rods 14 are arranged on the steel claws. After the anode block is placed on the supporting plate, the upper end of the conducting rod is just opposite to the hanging sleeve 17 above. The hanging sleeve is hung below the hanger 15 through a cable 16. The lifting appliance 15 is a circulating track for walking and conveying materials at the upper part of a workshop, and after the supporting plate inserts the conducting rod into the hanging sleeve 17, the anode block can be conveyed to the lower assembly line by the lifting appliance for repairing. Similarly, the repaired anode block conducting rod can be detached from the hanging sleeve through the reverse process.

In the falling stroke of the lifting platform, if impurities on the supporting plate need to be cleaned, the inserting shaft of the locking device can be pulled out, and the supporting plate can swing downwards around the axial direction of the supporting plate to be inclined or vertical as shown in fig. 5, so that the impurities on the supporting plate can fall into the lower trench 18. Obviously, the engagement or disengagement of the insert shaft and the supporting plate can be performed in an automatic control mode such as hydraulic pressure or the like, or can be performed manually. Because the pallet is flat with the support arm in the initial position, the insertion shaft is easy to install. When the impurities need to be cleaned, the anode block is hung, only the impurities are on the supporting plate, the weight is not large, and the inserting shaft is not difficult to manually extract.

The trench is also of a plurality of forms, and the trench is shown as an example at the front side of the frame, and two inclined blanking plates 19 are arranged in the trench to form a trapezoid section with wide upper part and narrow lower part. A vibration feeding plate 20 is arranged below the blanking plate, the vibration feeding plate is slightly inclined, a spring support is arranged below the vibration feeding plate, and a polarizer 21 is also arranged below the vibration feeding plate. Thus, the falling impurity materials can be sent away through vibration. Generally, the vibration feeding plate has a length of about 6m, and can feed materials to the main sealing machine for harmless treatment. The structure is simple, no station is occupied, the front side of the lifting machine can still carry out the procedures of feeding, overturning, discharging and the like, the upper and lower synchronization of the front side area and the rear side area is realized, and the stations are combined, so that the working efficiency is greatly improved.

Second embodiment: the improvement on the first embodiment. As shown in fig. 6, 7 and 8, there are two support arms, wherein at least one of the support arms is provided with a hydraulic tilt cylinder 22. The hydraulic tilt cylinder is one of hydraulic cylinders, and a plurality of enterprises such as Shanghai Xun Hao hydraulic technology limited companies exist in China for production and sales. The structure of the hydraulic swing cylinder is various, and a gear rack swing cylinder is exemplified in the figure. The cylinder is internally provided with a rack piston 23, namely, one side of the piston is provided with a rack which is meshed with a set of gears 24, and a gear shaft 25 extends outwards. The hydraulic tilt cylinder is characterized in that the piston and the gear synchronously move. The piston is pushed by high-pressure oil to move along the axial direction, so that the gear can be driven to swing at a certain angle, and the gear stops rotating when the movement of the piston stops. The hydraulic swing cylinder is arranged on the support arm, the gear shaft 25 of the hydraulic swing cylinder extends out in the horizontal direction and is connected with the support plate shafts fixed on the two sides of the support plate, so that the support plate can be driven to move, the support plate can be horizontally arranged, the support plate can swing, and the movement is sensitive, stable and reliable.

The installation mode of the hydraulic tilt cylinder mainly comprises two modes: a set of hydraulic tilt cylinders are arranged on a supporting arm on one side of a supporting plate, a concentric shaft seat is arranged on a supporting arm on the other side of the supporting plate and used for supporting a supporting plate shaft on the other side of the supporting plate, and the action of the supporting plate is controlled by the hydraulic tilt cylinders on one side. The other is that a set of hydraulic swing cylinders are respectively arranged on the supporting arms at the two sides of the supporting plate and are connected with the supporting plate shafts at the two sides of the supporting plate to jointly control the action of the supporting plate. Both of these approaches have advantages, which are all feasible.

As shown in figure 9, after the supporting plate moves upwards to complete the action of installing the anode block, the hydraulic swing cylinder moves downwards to drive the supporting plate to turn around the supporting plate shaft to be in an inclined or vertical state, impurities on the supporting plate fall into a lower trench, slide onto the vibration feeding plate along the blanking plate and then are sent to the main adhesive tape machine for harmless recovery treatment.

Third embodiment: the improvement is based on the foregoing embodiments. As shown in fig. 10, 11 and 12, the three-dimensional frame 2 is composed of four upright posts 1. The inner side of each upright post is provided with an upright slideway 9, and a lifting table 4 which can be driven by a power device to lift along the slideway is arranged in the frame. The lifting platform is a rectangular platform, and the power device is a hydraulic cylinder 3. There are also various ways of installing the hydraulic cylinder, four hydraulic cylinders are illustrated in the figure, and are respectively installed at the upper parts of the four slide ways. The piston rod 10 of the hydraulic oil cylinder is arranged in the slideway 9, and the four corners of the lifting platform are connected with the piston rod in the slideway through the sliding block 11. The lifting platform is provided with a supporting arm 5 which can stretch and retract along the horizontal direction under the drive of the power mechanism. The support arm has a plurality of structural forms, and the support arm is exemplified by a support arm with reference to fig. 16, 17 and 18 and is composed of two steel beams, the lower part of the support arm is supported by a pulley 27, and the upper part of the support arm is pressed by a pressing roller 26. The pulley and the press roller are fixed on the lifting platform. A rack 30 is arranged below the steel beam, a driving gear 28 driven by a hydraulic motor is arranged above the lifting table or on the inner side of the slideway, and the driving gear is matched with the rack on the lower side of the steel beam to drive the supporting arm to perform telescopic action. The hydraulic motor may be mounted on the lifting table, not shown, as it is conventional. One end of the support arm extends out of the frame and the outer end thereof is provided with a rotation shaft hole 31. The pallet illustrated in fig. 13, 14, 15, and 18 is a rectangular plate surface, and pallet shafts 8 are provided on both sides of the front end portion, and are fitted in the shaft holes 31 at the outer ends of the support arms. The inner edge of the supporting plate is propped against the frame and is in sliding fit. In order to reduce friction force and enable sliding to be smooth and labor-saving, rollers 29 can be arranged on two corners of the inner side edge of the supporting plate, and the rollers are propped against the outer sides of the stand columns.

The pallet is erected or tilted when the support arm is retracted within the frame. When the support arm extends to the outside of the frame, the outer edge of the support plate moves forward along with the support arm, and the inner edge of the support plate swings downwards around the outer support plate shaft, so that the whole support plate is horizontally arranged on the support arm, namely, the state shown in fig. 10 and 18. On the contrary, when the support arm is contracted inwards towards the frame, the outer side edge of the support plate moves along with the inner side edge, the inner side edge cannot move inwards due to the blocking of the upright post, and the support plate can only tilt or stand along the upper hem of the frame, namely, the state shown in fig. 20.

In operation, as can be seen in connection with fig. 19, the pallet is first laid flat, the lift table is placed under the frame, and one or both sets of anode blocks 12 are lifted by the forklift and placed on top of the pallet. Most of anode blocks are two groups, and the weight is more than 4 tons. The anode block is fixed by a steel claw 13, and a conductive rod 14 extending upwards is arranged on the steel claw. The anode blocks taken out from the electrolytic bath are broken and fall off integrally, and the anode blocks are required to be arranged in a tray, lifted up by a forklift and placed on a supporting plate. Generally, one tray can be loaded into two groups, and the weight of the tray is more than 8 tons. And then, starting the hydraulic oil pump to enable a piston rod of the oil cylinder to ascend and drive the lifting platform, the supporting arm, the supporting plate and the anode group above to upwards translate. After the end of the conductive rod on the anode block is inserted into the hanging sleeve 17 of the hanger 15 and locked by the hydraulic control device, the hanging action is completed. And then the cable can be conveyed to a repair line along with the operation of the lifting appliance for repair. At this time, the pallet is also provided with a tray and a large amount of broken garbage to be cleaned. For the former equipment, because the table top can not be turned over, the whole machine is required to be moved to another station for cleaning, and the operation is continued after the cleaning is carried out. The device is shown in fig. 20, the lifting platform is controlled to fall together with the supporting arm and the supporting plate, and meanwhile, the hydraulic motor is operated to drive the driving gear to reversely rotate, so that the supporting arm is driven to retract backwards, and the outer side edge of the supporting plate is driven to move inwards. Simultaneously, the edge of the inner side of the supporting plate swings upwards along the upright post, so that the supporting plate is inclined until the supporting plate is vertical, and the residual garbage on the supporting plate falls down by self weight. As shown in fig. 20, a trench 18 is formed downwardly in the ground below the pallet, and the trench passes below the present apparatus. Inclined blanking plates 19 are arranged on two sides of the trench inlet, and a vibration feeding plate 20 is arranged below the blanking plates. The vibration feeding plate can adopt a hard concave plate surface which is obliquely placed from front to back, and the polarizer 21 is arranged on the lower side surface of the plate. After the broken garbage slides down to the vibration feeding plate, the broken garbage can be pushed to the tail end of the plate surface. Generally, the stroke is about 6m, and the main adhesive tape machine can be connected for harmless treatment. Then, the lifting platform falls to the lowest point, the hydraulic system operates the driving gear to rotate forward, the supporting arm stretches forward, the supporting plate is pushed flat again, and then the anode blocks can be placed again.

The foregoing is briefly described as an assembly process for broken anode blocks. Similarly, the device can also take off the repaired anode block from the lifting appliance, and the operation process is opposite to the process, but the device has no problem of impurity cleaning. Therefore, in actual production, the method is more suitable for loading and unloading, namely, a group of anode blocks which are remained and old are inserted into the lifting appliance, then a group of anode blocks which are genuine are unloaded, and then garbage is cleaned once, so that the whole process is shorter in time and higher in operation efficiency.

Fourth embodiment: the hydraulic cylinder is improved in its mounting manner based on the third embodiment. As shown in fig. 21 and 22, two hydraulic cylinders 3 for driving the lifting table 4 to lift are respectively installed on both sides of the frame. Compared with the four cylinders in the previous example, the two cylinders are easier to synchronize in the action of the pistons, and the working performance is more stable and reliable.

Fifth embodiment: the roller mounting structure of the pallet is improved on the basis of the foregoing embodiments. As shown in fig. 23, a swing arm 32 extending toward the inside of the frame is provided at the inner side of the pallet 6, and a roller 29 is provided at one end of the swing arm. An upwardly extending and forwardly curved arcuate guide rail 33 is mounted on the lift table 4 and rollers are slidably engaged with the guide rail. When the supporting arm drives the supporting plate to move towards the direction in the frame, the roller swings forwards and upwards along the guide rail until the supporting plate is erected, and the structure ensures that the swinging of the supporting plate is more labor-saving.

To enhance the strength and stability of the frame, a reinforcing frame 34 may be added to the outside of the frame.

Sixth embodiment: the centralizer of the conductive rod is added on the basis of the previous embodiment. Because the broken anode blocks are irregular in shape, after the anode blocks are placed on the supporting plate, the positions of the conducting rods on the anode blocks are not necessarily completely perpendicular to the surface of the supporting plate, and the anode blocks can be inclined to the periphery, so that the difficulty of loading the lifting appliance is increased. Thus, a set of centralizers 35 is required to centralize the conductive rods. The centralizer may take a variety of forms, examples of which are herein described as a hydraulically powered mechanism for centralizing the conductive rod.

As shown in fig. 24 and 25, the centralizer has two centralizers 36, the main body of which is a long straight rod member, and the tail end of which is provided with a bending section 37 bent outwards and mounted at the front upper part of the frame through a centralizer shaft 38. The two centralizing rods are oppositely arranged and can swing reversely around the centralizing rod shaft. A front push rod 39 is arranged on the two centralizing rods, two centralizing wheels 40 are respectively arranged at two ends of the front push rod, and the two centralizing wheels are symmetrically pressed on the outer sides of the two centralizing rods. The front push rod 39 is vertically installed at the front end of the piston rod of the righting cylinder 43. The righting cylinder is installed at the upper part of the frame along the front-back direction. At least a pair of backward pushing oil cylinders 42 are arranged at the front part of one centralizing rod, and a backward pushing rod 41 is transversely arranged at the piston rod end of each backward pushing oil cylinder.

When the hydraulic centering device works, as shown in fig. 24, the outer ends of the centering rods are separated to two sides to form a V shape, the bending sections at the tail ends of the centering rods are positioned at two sides of the piston rod of the centering cylinder and are parallel to the axis of the piston rod, the front push rod at the front end of the piston rod of the front push cylinder is vertically pressed on the two bending sections, and the centering wheels at the two ends of the front push rod are clamped at two sides of the two bending sections. When the anode block is arranged on the supporting plate 6, the lifting table 4 starts to lift, when the conducting rod on the anode block enters the height of the righting rod, the righting oil cylinder starts to work, the piston rod drives the front push rod to move forwards, after the piston rod passes over the bending section, the two righting rods are pushed to swing inwards, and the position of the righting rod is shown in fig. 25, so that the conducting rod which is inclined in the left-right direction can be pushed to the middle position. When the piston rod is stopped in the forward direction, the front push rod is just arranged at the appointed position of the rear side surface of the conducting rod, and the backward inclination angle of the conducting rod can be corrected. Meanwhile, the rear pushing oil cylinder at the front end of the righting rod works, the piston rod of the rear pushing oil cylinder drives the rear pushing rod to move backwards, and when the rear pushing rod reaches the appointed position of the front side surface of the conducting rod, the rear pushing rod stops moving, so that the forward inclined angle of the conducting rod can be corrected. Under the condition, the deflection angles of the conductive rod in the front, the back, the left and the right directions are corrected, and the conductive rod can be accurately inserted into the hanging sleeve of the lifting appliance after rising along with the lifting platform. Then, the piston rods of the centralizing oil cylinders move reversely, centralizing wheels on two sides of the front push rod return to the original position, and meanwhile, the bending sections are forced to return, so that the two centralizing rods are opened again to return to the position shown in fig. 24.

The centralizer only illustrates that the centralizing of the conducting rod can be realized, but the centralizing of the conducting rod is not limited to the centralizing mechanism, and the mechanism capable of centralizing the conducting rod belongs to the same technical scheme.

Seventh embodiment: the improvement is based on the foregoing embodiments. The lifter is provided with an automatic control device. The automatic control device is in various forms, and fig. 26 illustrates a structure in which a plurality of touch switches 44, such as a touch switch for limiting the height position of the elevating platform, a touch switch for returning the elevating platform to the initial position, a load sensor signal of the turning plate, a tilting signal of the turning plate, a start signal of the vibration feeding plate, etc., are mounted on the upright posts of the frame. Each signal source transmits signals to the processor, and the processor sends out action instructions after processing, so that the whole intelligent control is realized.
