Definitions
- the invention relates to plants for the production of aluminum by igneous electrolysis according to the Hall-Héroult process. It relates more particularly to the handling devices used in said factories.
- Aluminum metal is produced industrially by igneous electrolysis, namely by electrolysis of alumina in solution in a bath of molten cryolite, called electrolyte bath, according to the well-known Hall-Héroult process.
- the electrolyte bath is contained in cells, called “electrolysis cells", comprising a steel box, which is coated internally with refractory and / or insulating materials, and a cathode assembly located at the bottom of the cell.
- Anodes typically made of carbonaceous material, are partially immersed in the electrolyte bath.
- the assembly formed by an electrolysis tank, its anodes and the electrolyte bath is called an electrolysis cell.
- the factories contain a large number of electrolysis cells arranged in a line, in buildings called halls or electrolysis rooms, and electrically connected in series using connecting conductors, so as to optimize the floor occupation of factories.
- the cells are generally arranged so as to form two or more parallel lines which are electrically linked together by end conductors. The electrolysis current thus cascades from one cell to the next.
- an electrolysis plant requires work on the electrolysis cells, including the replacement of used anodes. by new anodes, the removal of liquid metal from the cells and the removal or addition of electrolyte.
- the most modern factories are equipped with a lifting and handling unit comprising an overhead crane, which can be translated above and along the electrolysis cells, and a trolley fitted with several handling elements and intervention (often called "tools"), such as shovels and hoists.
- the handling member which is intended for handling and moving loads such as anodes comprises a clamp capable of gripping the load, called a "handling clamp".
- a clamp capable of gripping the load
- this clamp is placed near the rod of the anode intended to be gripped, then closed on the rod sufficiently to allow the anode to be lifted. The anode is then moved, then positioned or deposited in the desired location.
- the Applicant has therefore sought handling tongs which make it possible to avoid these drawbacks while remaining reliable, simple and of reduced bulk.
- the subject of the invention is a handling clamp intended for the industry of the production of aluminum by igneous electrolysis, capable of gripping a charge by a gripping member (called a "rod” thereafter) fixed to said charge, and comprising locking means capable of preventing the opening of the clamp when the load is suspended by the latter.
- the handling clamp according to the invention which is intended to grip a load provided with a rod, comprises: - at least one movable gripping member, typically a jaw, having an open position and a closed position,
- - connecting means capable of limiting the axial displacements of the rod in the clamp between a first so-called “low” position and a second so-called “high” position when the gripping member (s) are in the closed position
- At least one locking system preferably mechanical, capable of blocking the said gripping member (s) in the closed position when it is locked (or “engaged"), said locking system being locked when the rod is in the low position and unlocked (“disengaged") when the rod is in the high position.
- the Applicant has had the idea of providing the clamp with a locking system which is locked or unlocked by the mere movement of the rod in the clamp.
- the locking system blocks the gripping member (s) in the closed position, preventing the opening of the clamp and the release of the rod.
- the locking is therefore controlled by the presence and the position of the rod in the clamp, which avoids untimely drops of the load in the event of failure of the actuation means of the movable gripping member (s) of the clamp.
- the invention also relates to the use of the handling tongs according to the invention in an aluminum production plant by igneous electrolysis, in particular for handling anodes made of carbonaceous or other material.
- the invention also relates to a lifting and handling unit comprising at least one load handling member (typically anodes) provided with a handling clamp according to the invention.
- load handling member typically anodes
- FIG. 1 illustrates a typical electrolysis room, seen in section, intended for the production of aluminum.
- FIG. 2 illustrates, in profile view, a handling clamp according to the invention.
- FIG. 3 illustrates, in profile view, the mobile elements of a handling clamp according to the invention.
- FIG. 4 illustrates a handling clamp according to the invention, seen in longitudinal section along two perpendicular planes (planes A-A and B-B).
- FIG. 5 illustrates the operation of the locking system of the handling clamp according to the invention using a particular example.
- Electrolysis plants for the production of aluminum include a liquid aluminum production area which includes one or more electrolysis rooms (1).
- each electrolysis room (1) comprises electrolysis cells (2) and at least one lifting and handling unit, or "service machine", (6, 7, 8 , 9, 10).
- the electrolysis cells (2) are normally arranged in rows or rows (typically side-by-side or head-to-head), each row or row typically comprising one or more hundreds of cells.
- Said cells (2) comprise a series of anodes (3) provided with a metal rod (4) intended for fixing and electrical connection of the anodes to a metallic anode frame (not illustrated).
- the anode rod (4) is typically of substantially rectangular or square section.
- the lifting and handling unit (6, 7, 8, 9, 10) is used to carry out operations on the cells such as changing the anode or filling the feed hoppers with ground bath and A1F 3 electrolysis cells. It can also be used to handle various loads, such as tank elements, pockets of liquid metal or anodes.
- Said unit (6, 7, 8, 9, 10) typically comprises an overhead crane (6), a carriage (7) capable of moving on the overhead crane (6), and handling and intervention devices (often called “tools") (8, 9, 10), such as a cabin (8) for the operator, a shovel or crust tongs ( not shown), a picker (not shown) or a. handling member (9) provided with a gripper or handling clamp (10). The latter member is particularly intended for handling the anodes (3), although it can also be used for handling other loads.
- the overhead crane (6) rests and travels on raceways (11, 12) arranged parallel to each other and to the main axis - and typically longitudinal axis - of the hall (and of the cell file).
- the traveling crane (6) can thus be moved along the electrolysis room (1).
- the handling clamp (10) which is intended to grip a rod (4) fixed to a load (3) - typically an anode - and provided with at least one connecting means (5, 5a, 5b), typically a cavity, comprises:
- At least one connecting means (101a, 101b) able to cooperate with the connecting means or means (5, 5a, 5b) of the rod (4) so as to limit the axial displacements of the rod (4) in the clamp (10) between a so-called “low” position and a so-called “high” position when the or each gripping member (100a, 100b) is in the closed position,
- At least one locking system capable of blocking the or each gripping member (100a, 100b) in the closed position when it is locked, and capable of being locked when the rod (4) is in the low position and unlocked when the rod (4) is in the high position.
- the gripping member or members In the open position, the gripping member or members provide sufficient space to allow insertion of the rod into the clamp.
- the or each gripping member (100a, 100b) is advantageously able to pivot around an axis (105).
- the clamp (10) typically comprises two gripping members (100a, 100b), which are advantageously able to pivot around an axis (105) specific to each gripping member or common to the two gripping members.
- the clamp (10) is then typically symmetrical with respect to an axis C, called “central axis", which can coincide with the axis of the rod (4).
- the axis (s) (105) are preferably substantially perpendicular to the axis C, so as to be substantially horizontal in use.
- the connecting means (101a, 101b) of the clamp (10) typically comprise a projection on the or each gripping member (100a, 100b) and the corresponding connecting means or means (5, 5a, 5b) of the rod ( 4) include at least one cavity.
- the projection (s) (101a, 101b) of the or each gripping member (100a, 100b) are able to cooperate with the corresponding cavity (s) (5, 5a, 5b) of the rod (4) so as to limit the displacements axial of the rod (4) between said low and high positions when the or each gripping member (100a, 100b) is in the closed position.
- the dimensions of the connecting means (101a, 101b, 5, 5a, 5b) are such that, when engaged, the rod (4) can still be moved between the high position, in which the locking system (120) is unlocked (as shown in Figure 5 (E)), and the down position, in which the locking system (120) is locked (as shown in Figure 5 (F)). This can be obtained by fitting one or more cavities (5, 5a, 5b) with sufficient clearance to allow these movements.
- the connecting means (101a, 101b) of the clamp (10) and the corresponding connecting means (5, 5a, 5b) of the rod (4) are advantageously such that they substantially limit - and possibly prevent - the rotation of the rod (4) about its axis A, which ensures precise positioning of the load attached to the rod, generally an anode.
- the clamp further comprises a clamp body (109) and a fixing means (108). The latter makes it possible in particular to fix the clamp (10) to a handling member (9).
- the locking system (120) comprises at least one locking element (102a, 102b), such as a tooth or a hook, fixed to each gripping member (100a, 100b ), and at least one movable lock (121) having at least a first position called “locking” and a second position called “unlocking", said lock (121) being:
- the locking system (120) of the clamp (10) is locked (or “engaged") when, at the same time, the gripping member (s) (100a, 100b) are in the closed position and the rod (4) is in the low position, which typically occurs when the load is suspended by the clamp (10), and it is unlocked when the rod (4) is in the high position, which typically occurs when the clamp ( 10) pushes on the rod (4).
- the clamp (10) according to the invention thus allows locking or unlocking of said locking system (120) by a simple relative movement of the rod (4) relative to the clamp (and typically in the clamp).
- the bolt locking position (121) is typically a low position and the unlocking position is typically a high position, this which allows the locking system (120) to be locked by the effect of gravity.
- the latch (121) is advantageously able to be moved along a central axis of symmetry C of the clamp (10).
- the lock (121) is typically provided with at least one cavity (126a, 126b), such as a notch or a mortise, capable of cooperating with the or each locking element (102a, 102b) so as to prohibit the movement of the or each gripping member (100a, 100b) from the closed position to the open position.
- a cavity such as a notch or a mortise
- the lock (121) has a waiting position - which is typically said locking position but which may be different from this - and is located in the clamp so that the rod (4) can move from the waiting position to the unlocking position when it is inserted into the clamp.
- the lock (121) may include a pushing member (124), such as a stud, and is capable of being moved from the standby position to said unlocking position by a pushing of the rod (4 ) - and more precisely the end (4 ') of the rod (4) - on said thrust member (124).
- Said thrust member (124) is typically located near the end (127) of the latch (121) located on the side of the opening of the clamp.
- the clamp (10) may further comprise at least one guide piece (122, 123) capable of guiding the movement of the latch (121) during its movements between its different positions.
- the clamp (10) comprises a first guide piece (122) capable of sliding inside the lock (121) and a second guide piece (123) able to guide the 'low' end (127) of the lock (121).
- the first guide piece (122) is typically fixed to a ball joint or a transverse or axial axis.
- the second guide piece (123) also acts as a stop.
- the locking system (120) further comprises at least one return means, such as an elastic element, (125) able to cause the lock (121) to move from the unlocked position to the locked position, and able to keep it in the latter position, when the or each gripping member (100a, 100b) is in the closed position and the rod (4) is in the low position.
- the return means (125) which is typically a spring, is advantageously integrated into the lock (121) in order to isolate it from the environment and, possibly, to lubricate it, in order to maintain its elasticity and avoid its deterioration.
- the return means (125) is advantageously located in a recess inside the lock (121) and / or in a recess inside a guide piece (122) of the lock.
- the return means (125) is located partly in a recess inside the lock (121) and partly in a recess inside a guide piece ( 122) of the lock.
- the locking system (120) further comprises at least one means, called blocking means, capable of holding the or each gripping member (100a, 100b) in the open position when the lock (121 ) is in the locked position or in the standby position, as illustrated in Figures 5 (B), 4 (B) and 4 (C).
- blocking means make it possible to mechanically prohibit the closing of the clamp when the rod is not placed correctly in the latter, in particular when the rod is not placed in the clamp so as to allow the engagement of the means of connection (101a, 101b, 5, 5a, 5b) between the rod and the clamp.
- This variant also allows unhindered insertion of the rod into the clamp.
- Said locking means are advantageously formed by the bolt (121) and the locking elements (102a, 102b) which are then such that said elements are supported on the bolt when the latter is in the waiting position (typically the position locking), so as to prohibit the closing of the gripping member (s).
- the clamp (10) may further comprise one or more guide parts (103, 104) of the rod (4) to ensure satisfactory positioning of the latter between the gripping members (100a, 100b) of the clamp.
- the insertion of the rod (4) into the clamp can possibly be limited by a stop (123).
- the gripping members (100a, 100b) and / or the guide piece or pieces (103, 104) preferably define a cavity which matches the shape of the rod so as to limit, or even prevent, rotation.
- FIGS 3 and 4 illustrate a clamp (10) in which the actuation system (110) comprises two connecting rods (114a, 114b) and an actuator (112), which is typically a jack.
- the actuator (112) and the connecting rods (114a, 114b) are typically connected by a common actuation axis (1 13) fixed to the actuation rod (111) of the actuator.
- This variant has the advantage of being simple, reliable and effective.
- the pliers according to the invention advantageously comprises two movable gripping members (100a, 100b) and the latch (121) is preferably located between these two gripping members. This configuration allows a compact construction and protects the lock from impact with external elements.
- the locking system (120) is preferably entirely mechanical, such as that illustrated in FIGS. 3 to 5, in order to avoid the failure modes linked to electrical or electromechanical elements.
- the gripping members (100a, 100b) can pivot freely around their respective (or common) axis (105) and allow, in particular, positioning of the locking element (s) (102a, 102b) opposite each corresponding cavity (126a, 126b) and the engagement of the connecting means (101a, 101b, 5, 5a, 5b), typically by introduction of the projections (101a, 101b) in the corresponding cavities (5, 5a, 5b) of the rod (4).
- the gripping members (100a, 100b) are locked when the clamp (10) is pulled up and the rod (4) descends under the effect of its own weight and that of the load ( Figure 5 (E) ).
- the descent of the rod (4) is stopped by the connecting means (101a, 101b, 5, 5a, 5b).
- the locking element (s) (102a, 102b) are inserted into the corresponding cavity (ies) (126a, 126b) and cooperate with them so as to prevent the opening of the gripping members (100a, 100b) of the clamp (10) ( Figure 5 (F)).
- Lockout is effective as long as the load is suspended.
- the locking system is unlocked by raising the rod in the clamp, which is typically achieved by pressing the load.
- Such a system has the advantage of not requiring additional actuators and thus increasing the reliability of the device. It also has the advantage of ensuring a locking action independently of the weight of the load and the friction force between the connecting means (101a, 101b, 5, 5a, 5b).
- the latch (121) has a waiting position ( Figures 5 (A) and 5 (B)) which merges with the locking position ( Figure 5 (F)).
- the locking elements (102a, 102 b) cooperate with the lock (121), by pressing on the latter, so as to prevent the closing of the clamp as long as the rod (4) is not deep enough to allow alignment of the projections (101a, 101b) and cavities (5, 5a, 5b).
- the locking elements (102a, 102b) cooperate with the latch (121) by a cam effect.
- the invention also relates to a lifting and handling unit (6, 7, 8, 9, 10) comprising at least one load handling member (such as anodes) (9) provided with a handling clamp (10) according to the invention.
- the invention makes it possible to avoid dual-control systems. It also has the advantage of being practically insensitive to acceleration during handling.
- Rod typically an anode rod
- Rod connecting means typically cavities
- 101a, 101b Means for connecting the clamp, typically projections
