Description

Technical Field

[0001] The invention belongs to the field of sling equipment, relates to cathode carbon blocks of aluminum electrolytic cells, and in particular to a sling for slinging carbon blocks capable of turning over. Background Art

[0002] Carbon blocks play an important role in the electrochemical industry, especially in the aluminum electrolysis process. They can be classified into anode carbon blocks and cathode carbon blocks according to their uses. Anode carbon blocks are mainly used in the aluminum electrolysis process, and their main function is to act as anodes in the electrolytic cell and participate in electrochemical reactions. Anode carbon blocks have good electrical conductivity and can transfer current to the electrolyte in the electrolytic cell to promote the electrochemical reaction. In the electrolytic production of aluminum, anode carbon blocks participate in redox reactions, in which carbon materials are oxidized in the reaction and release electrons. These electrons flow to the cathode through the circuit to help reduce metallic aluminum. Cathode carbon blocks are the cathode materials of aluminum electrolytic cells, mainly made of raw materials such as anthracite and metallurgical coke. Cathode carbon blocks have the characteristics of good electrical conductivity, high thermal stability, and high mechanical strength. They can improve the efficiency and life of aluminum electrolytic cells and reduce energy consumption and production costs. At the same time, cathode carbon blocks also play an important role in environmental protection and can reduce pollution emissions in the aluminum electrolytic production process. Carbon blocks are large in size and heavy in weight, and require the use of lifting equipment such as cranes during the transfer and installation process to complete the corresponding operation process.

[0003] The existing patent CN201520078508.3 discloses a cathode carbon block turning device for an aluminum electrolytic cell, including a cathode carbon block, a lifting and turning frame is arranged above the cathode carbon block, a reducer is arranged at the middle position of the lifting and turning frame, a transverse transmission shaft is arranged on the lifting and turning frame, the transmission shaft is directly connected to the reducer, gears are arranged at both ends of the lifting and turning frame, a fall chain is connected to the gear, a lifting belt is connected to the bottom of the fall chain, and the lifting belt is directly wrapped around the cathode carbon block. The flipping device can realize the flipping operation of the cathode carbon block and improve the mechanization degree of the workshop. However, there are still some problems in the actual application of the flipping device. For example, first, the carbon block and the lifting belt in the device need to be wrapped with multiple circles. Otherwise, due to the prismatic structure of the carbon block, there will be instantaneous slippage during the flipping process, affecting the stability of the sling; second, due to the small arrangement gap between adjacent carbon blocks after they fall, if the lifting belt is pulled out at the end of the lifting, not only will the withdrawal resistance be large, but the lifting belt will also be frequently worn, which will affect the service life and safety of the lifting belt and the work efficiency of the workshop.

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying drawings themselves, and do not limit the structure.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] Examples, such as Figure 1-Figure 9 As shown, the present invention provides a reversible charcoal block hoisting sling, comprising a hoisting beam 1, on which a hanger 2 connected in a triangular shape is arranged, and chain hanger assemblies 3 are arranged at both ends of the hoisting beam 1, and a hoisting belt assembly 4 is arranged at the hoisting end of the chain hanger assembly 3. The hoisting beam 1 adopts a steel square tube structure, and each side arm of the hanger 2 adopts a double steel plate structure to ensure that the hoist has sufficient structural strength and tensile strength. On this basis, the present invention provides a transverse axis 5 which horizontally passes through the suspension beam 1 at the center of the suspension beam 1, and end head assemblies 6 which cooperate with the ends of the suspension beam 1 are provided at both ends of the transverse axis 5, and the end head assembly 6 includes a slot plate 61, and the slot of the slot plate 61 faces the middle direction of the transverse beam, and the slot plate 61 is provided with an axial hole hinged to the hanger 2, and the end of the slot plate 61 is provided with an end tube 62 nested with the transverse axis 5, and an angle steel plate 63 is provided at the middle bottom of the slot plate 61, and the angle steel plate 63 is provided with a hanging hole 64 connected with the chain hanger assembly 3, and a ring beam 7 is provided on the outer side of the slot plate 61, and a track 71 with a C-shaped horizontal cross-section is provided inside the ring beam 7, and a sliding hinge 8 is provided in the track 71, and an electric hoist 9 is provided at the bottom of the sliding hinge 8, and a rotating connecting buckle assembly is provided at the lifting end of the electric hoist 9 10. The rotating connecting buckle cooperates with the lifting belt assembly 4. The lifting belt assembly 4 includes a main belt 41 and an auxiliary belt 42. The fracture of the main belt 41 is O-shaped. Both ends of the main belt 41 are provided with main lifting holes 43 for connecting with the chain sling assembly 3. The main belt 41 is provided with two inner holes 44 distributed near its two ends and two outer holes 45 located between the inner holes 44. One end of the auxiliary belt 42 enters from one inner hole 44 and passes out from one outer hole 45, and the other end of the auxiliary belt 42 enters from another inner hole 44 and passes out from one outer hole 45. The main belt 41 and the auxiliary belt 42 form a circular elastic clamping hole 46 for cooperating with the carbon block 12. The two ends of the auxiliary belt 42 overlap on the outside of the main belt 41 and are provided with auxiliary lifting holes 47 for cooperating with the rotating connecting buckle assembly 10 in the overlapping part.

[0030] Specifically, the lifting belt assembly 4 adopts a composite design of a main belt 41 and an auxiliary belt 42. An elastic clamping opening 46 with an adjustable caliber is formed by threading the main belt 41 and the auxiliary belt 42. The elastic clamping opening 46 is used to be put on the carbon block 12. The main lifting hole 43 and the auxiliary lifting hole 47 of the lifting belt assembly 4 are respectively connected by the chain sling assembly 3 and the rotating connecting buckle assembly 10. The elastic clamping opening 46 is automatically tightened during the lifting process, and the main belt 41 forms a circle around the carbon block 12, and the auxiliary belt 42 also forms a circle around the carbon block 12. With the main lifting hole 43 as the fixed center, the main belt 41 plays the main lifting role by controlling the electric hoist 9 to descend. The main belt 41 is fully capable of lifting the carbon block 12 alone. At this moment, the load of the auxiliary belt 42 is greatly reduced. By pulling the electric hoist 9 to move along the matching track of the sliding hinge 8 and the track 71, and making the auxiliary belt 42 bypass the carbon block 12, until the electric hoist 9 goes around the other end of the ring beam 7, the electric hoist 9 is controlled to rise again to complete the flipping operation of the carbon block 12. During the flipping process, the elastic clamping mouth 46 formed by the carbon block 12, the main belt 41 and the auxiliary belt 42 remains basically unchanged under the action of friction until the flipping action is completed. The carbon block 12 can stably complete the direction transition, which is conducive to ensuring the safety of the lifting process. Finally, the elastic clamping mouth 46 of the lifting belt assembly 4 is slightly loosened, and it can be removed from both ends of the carbon block 12 to carry out the next cycle of lifting operation. The device is reasonably designed and has good lifting stability, which reduces the friction frequency of the lifting belt, is beneficial to prolonging the actual service life of the lifting belt assembly 4, is beneficial to improving the safety factor of the lifting operation, and is also beneficial to improving the work efficiency of the workshop.

[0031] like Figure 4 and Figure 5 As shown, the chain sling assembly 3 includes a circular steel hook 31, a chain 32 is provided at the bottom of the circular steel hook 31, a ring 33 is provided at the bottom of the chain 32, the ring 33 is sleeved on the first pulley member 34, and a self-locking hook 35 is provided at the bottom of the first pulley member 34, and the self-locking hook 35 cooperates with the main lifting hole 43. The circular steel hook 31 is larger in specifications than the chain 32, including the thickness and length and width, which is conducive to improving the structural strength of the hanging end of the chain sling assembly 3. As for the hanging hole 64, at least two hanging holes 64 are provided on the angle steel plate 63, which are used to fine-tune the horizontal position of the chain sling assembly 3. The bottom of the chain 32 adopts the design of the ring 33 and the first pulley member 34, which can facilitate manual control of the angle of the self-locking hook 35 before lifting so as to better hang it on the main lifting hole 43, and the self-locking hook 35 has a self-locking function, which can ensure its reliability and safety after establishing a lifting relationship with the main belt 41.

[0032] In order to improve the combined performance of the ring beam 7, the suspension beam 1 and the hanger 2, the cross section of the ring beam 7 provided by the present invention is C-shaped and both ends are provided with end plates 72 that cooperate with the end head assembly 6. The end plates 72 are provided with hinge holes corresponding to the shaft holes. The hinge holes, the shaft holes and the hanger 2 are connected through the reinforcing shaft 73. Both ends of the reinforcing shaft 73 are provided with shaft caps 74 that are threadedly connected thereto. The shaft caps 74 are used to prevent the reinforcing shaft 73 from moving left and right. As for the reinforcing shaft 73, it adopts a multi-section shoulder design to support the hanger 2, the slot plate 61 and the end plate 72 in sections, and the shaft diameter of the reinforcing shaft 73 adopts a thicker shaft diameter to ensure that it has higher shear strength and compressive strength.

[0033] In order to improve the matching performance between the track 71 and the sliding hinge 8, the longitudinal section of the track 71 provided by the present invention is T-shaped, and the sliding hinge 8 includes a circular plate section matching with the head end of the T-shape and a straight rod section matching with the vertical part of the T-shape. A mold plate is provided at the bottom of the straight rod section, and the mold plate is hinged with the top lifting ear of the electric hoist 9. The side of the ring beam 7 is provided with a peripheral hole 75 connected with the track 71. The two ends of the peripheral hole 75 close to the blocking plate are blocking ends, and a movable rod radially connected with the sliding hinge 8 is provided in the peripheral hole 75. In this way, the blocking ends at both ends of the peripheral hole 75 can be used as the limiting nodes of the maximum range of motion of the movable rod to prevent the sliding hinge 8 from rotating excessively in the track 71; at the same time, the movable rod can share a part of the supporting reaction force received by the sliding hinge 8, which is used to improve the smoothness of the passive traction of the sliding hinge 8 for moving.

[0034] Furthermore, the present invention provides an indicator light 11 at the end of the movable rod. The indicator light 11 has its own power supply. The light indication function of the indicator light 11 can improve the controllability of the worker pulling the electric hoist 9 to perform the rotation action, which is beneficial to improving the working efficiency.

[0035] like Figure 1 , Figure 5 and Figure 7As shown, the rotating connecting buckle assembly 10 includes a second pulley component 101, and the second pulley component 101 cooperates with the steel rope of the electric hoist 9. A rotating hinge 102 connected to the second pulley component 101 in a cross shape is provided at the bottom of the second pulley component 101, and a pair of boom plates 103 are provided at the bottom of the rotating hinge 102. Two connecting holes 104 spaced apart vertically are provided on the boom plates 103, and a pair of sliding tubes 105 corresponding to the connecting holes 104 are provided between the boom plates 103, and bolts 106 connecting the auxiliary hanging hole 47 and the connecting hole 104 are provided inside the sliding tubes 105. Among them, the second pulley component 101 cooperates with the steel rope. The second pulley component 101, as a movable pulley, can be lifted and lowered by the unwinding action of the electric hoist 9 on the steel rope, and has good lifting stability; the rotating hinge 102 can rotate around the vertical axis connected to the second pulley component 101, especially when the electric hoist 9 carries the auxiliary belt 42 to revolve to the other end of the ring beam 7, the rotation function of the rotating hinge 102 can cause the boom plate 103 to flip accordingly, thereby ensuring that the auxiliary belt 42 will not be twisted, so as to ensure the lifting stability of the lifting belt assembly 4 to the carbon block 12.

[0036] Furthermore, the boom plate 103 and the two sets of sliding tubes 105 form a connecting buckle with a certain vertical span, which can provide a longer matching length for the auxiliary lifting hole 47 and the rotating connecting buckle assembly 10 on the basis of ensuring that the auxiliary belt 42 has sufficient descending space, which is beneficial for the two ends of the auxiliary belt 42 to obtain a certain range of motion, avoiding extreme pulling between the top of the auxiliary lifting hole 47 and the sliding tube 105, and is beneficial to extending the actual service life of the auxiliary belt 42, thereby improving the safety lifting factor of the equipment.

[0037] In order to improve the matching performance between the sliding tube 105 and the boom plate 103, the sliding tube 105 provided by the present invention includes a left tube body 1051 and a right tube body 1052. The left tube body 1051 and the right tube body 1052 are threadedly connected. The actual length of the sliding tube 105 can be adjusted by adjusting the screwing depth of the left tube body 1051 and the right tube body 1052. On the one hand, the tensioning effect between the sliding tube 105 and the boom plate 103 is controlled to improve the structural strength of the rotating connecting buckle assembly 10. On the other hand, it can avoid the occurrence of gaps between the boom plates 103 and the sub-belt 42 being stuck on the threaded surface of the bolt 106, thereby ensuring that the sub-belt 42 maintains a certain flexibility during the lifting process, especially avoiding knotting and blockage during the switching process.

[0038] In order to ensure the matching performance between the auxiliary belt 42 and the sliding tube 105, the present invention is provided with a retaining ring 1053 at the end of the left tube body 1051 and the right tube body 1052, so that before the auxiliary belt 42 is lifted, the auxiliary belt 42 and the sliding tube 105 can be assembled in advance, and the maximum width distance between the two ends of the auxiliary belt 42 can be controlled, which is conducive to reducing the difficulty of synchronously installing the sliding tube 105 and the auxiliary belt 42 between the booms, thereby improving the assembly efficiency and actual utilization rate of the equipment.

[0039] Furthermore, the length of the left tube body 1051 provided by the present invention is greater than that of the right tube body 1052. The left tube body 1051 is connected to the preload spring 107. By installing the preload spring 107, the efficiency of synchronously installing the two sliding tubes 105 between the boom plates 103 can be improved, thereby preventing the two sliding tubes 105 from moving freely.

[0040] In order to improve the immediacy of the movement of the sliding hinge 8 along the track 71, the present invention is provided with a plurality of evenly distributed spherical rollers on the top surface of the sliding hinge 8, and the top surface of the spherical rollers is in rolling support with the inner top surface of the track 71. The design of the spherical rollers can reduce the movement resistance of the sliding hinge 8 in the track 71, and reduce the resistance of the worker pulling the handle rope to drive the entire electric hoist 9 to move, thereby improving the flexibility of the electric hoist 9 to move. It should be noted that if the rotating connecting buckle assembly 10 is lifted to a certain height together with the auxiliary belt 42, the auxiliary belt 42 and the main belt 41 both apply a lifting tension, so the sliding hinge 8 will not move freely under pressure, which can ensure the stability of the carbon block 12 during the passive lifting process.

[0041] like Figure 6 As shown, the angle steel plate 63 includes an angle socket 65 matched with the bottom surface of the suspension beam 1, the top of the angle steel plate 63 is welded to the end tube 62, one side of the angle socket 65 is welded to the slot plate 61, and the top of the end tube 62 is provided with at least one pair of countersunk holes distributed axially, and the countersunk holes are provided with countersunk bolts 66 for connecting the end head assembly 6 and the horizontal axis 5. By designing the angle socket 65, the contact span between the end head assembly 6 and the bottom of the suspension beam 1 can be increased, and on the basis of ensuring the stability of the clamping of the end head assembly 6 and the suspension beam 1, more opening nodes of the hanging holes 64 can also be increased. Through the connection of the countersunk bolts 66 to the end head assembly 6 and the horizontal axis 5, the effect of clamping the suspension beam 1 can be further achieved, thereby ensuring the stability of the end head assembly 6 at both ends of the suspension beam 1.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
