Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum electrolysis, and particularly relates to an aluminum electrolysis anode clamp. BACKGROUND

[0002] The aluminum electrolysis anode clamp is one of the most important tools in the aluminum electrolysis workshop, and is mainly used for clamping the aluminum anode to ensure that the aluminum anode can smoothly undergo the electrolysis reaction. The upper part of the aluminum anode is usually provided with a lifting hole, so that the aluminum anode can be conveniently lifted, moved and placed at a correct position by using lifting equipment such as a lifting hook, a lifting belt and the like, thereby ensuring the continuous electrolysis process.

[0003] In the related art, the anode clamp generally adopts the form of an oil cylinder cooperating with a spring. When the anode needs to be clamped, the control system sends a signal to the oil cylinder, so that the hydraulic oil pressure in the oil cylinder is increased, thereby pushing the clamp body to open. Then, the anode is placed in the clamp, and the control system sends a signal to the oil cylinder again, so that the hydraulic oil pressure in the oil cylinder is reduced, the clamp body is closed under the action of the spring, and the anode is clamped under the action of the oil cylinder. However, this will cause the spring to be first stretched every time the anode clamp is lifted and placed, and the oil cylinder will bear an excessive load, thereby shortening the service life of the oil cylinder. CONTENT OF THE UTILITY MODEL

[0004] The aluminum electrolysis anode clamp provided by the embodiments of the present application can solve the technical problem that the spring needs to be first stretched every time the anode clamp is lifted and placed in the related art, and the oil cylinder will bear an excessive load, thereby shortening the service life of the oil cylinder.

[0005] The aluminum electrolysis anode clamp provided by the embodiments of the present application is used for lifting the aluminum anode, and includes a frame body, two clamps and a lifting device. The two clamps are rotationally arranged on the frame body, and a gap is formed between the two clamps. The clamp is provided with a clamping portion on one side opposite to the other clamp. The clamping portion has a first guide surface facing downward. The lifting device includes a contact block movably arranged on the frame body. The contact block has a movement path movably arranged in the gap. When the contact block moves into the gap, the contact block contacts the clamp to limit the rotation of the two clamps in opposite directions.

[0006] The aluminum electrolysis anode clamp based on the embodiments of the present application is in contact with the aluminum anode. Under the contact of the aluminum anode, the two clamps are relatively far away from each other. Under the action of gravity, the clamps are reset to clamp the aluminum anode by the clamping portion. Since the contact block can contact the clamps to limit the rotation of the two clamps in opposite directions, the stability of clamping is ensured.

[0007] In some embodiments, the clamp includes a rotating portion rotationally arranged on the frame body. The outer circumferential side wall of the rotating portion has a protruding portion. When the contact block moves into the gap, the contact block contacts the protruding portion to limit the relative approach of the two protruding portions.

[0008] Based on the above embodiment, the rotation of the whole clamp is limited by the abutting of the protrusions and the abutting blocks, and the two protrusions clamp the two sides of the abutting blocks respectively, so that the stress is uniform.

[0009] In some embodiments, the lower end of the clamp has a second guide surface facing downward, and the upper end of the second guide surface does not exceed the lower end of the first guide surface in height.

[0010] Based on the above embodiment, the presence of the second guide surface enlarges the distance between the lower ends of the two clamps, facilitating the aluminum electrode to enter between the two clamps.

[0011] In some embodiments, the frame body includes a horizontal plate and side plates on both sides of the horizontal plate, the two side plates are arranged along a first preset direction, the two clamps are arranged along a second preset direction, the first preset direction and the second preset direction are both parallel to the horizontal direction, and the first preset direction and the second preset direction are perpendicular to each other.

[0012] Based on the above embodiment, the force balance of the whole anode clamp is ensured, and the position of the rotation of the clamp is provided, the rotation shaft is arranged between the two side plates, and the rotation shaft is also prevented from being polluted by the external environment.

[0013] In some embodiments, the lower end of each of the two side plates is provided with a guide plate, and the distance between the two guide plates gradually increases from top to bottom.

[0014] Based on the above embodiment, the guide plate plays a certain guiding role, facilitating the aluminum electrode to enter between the two clamps.

[0015] In some embodiments, a reinforcing plate is connected between the two side plates.

[0016] Based on the above embodiment, the side plates are less likely to be deformed, the strength of the frame body is greatly improved, and the stability of the whole anode clamp is ensured.

[0017] In some embodiments, the width of the reinforcing plate in the second preset direction satisfies that the reinforcing plate abuts against the clamps when the two clamping portions are in a horizontal state.

[0018] Based on the above embodiment, the reinforcing plate also has a certain buffering effect, avoiding the clamps from colliding with the aluminum anode when the clamps are reset under the action of gravity and external force, and playing a role in protecting the aluminum anode.

[0019] In some embodiments, a resilient member is further connected between the two clamps.

[0020] Based on the above embodiment, the resilient member can provide a certain pulling force, facilitating the two clamps to be quickly reset, and preventing the clamps from shaking during hoisting and transportation, so as to ensure the stability.

[0021] In some embodiments, the lifting device further comprises a hydraulic assembly, which is mounted on the frame body and connected with the abutting block.

[0022] Based on the above-mentioned embodiments, the hydraulic assembly can bear larger load and has higher stability.

[0023] In some embodiments, the hydraulic assembly comprises a cylinder, a piston rod and a cover, the cylinder is mounted on the cover, the piston rod is connected with the cylinder and the abutting block, and the cover is mounted on the frame body and encloses the frame body to form a channel, and the piston rod is arranged in the channel.

[0024] Based on the above-mentioned embodiments, the dust in the external environment, especially the falling dust, can be reduced to avoid polluting the piston rod in the hydraulic assembly and affecting the normal use of the hydraulic assembly.

[0025] Based on the aluminum electrolysis anode clamp, when the anode clamp is lowered, the clamping portions on the two clamps contact the aluminum anode, the two clamps are gradually separated under the action of the first guide surface, then continue to be lowered, the first guide surface does not contact the aluminum anode, the clamps are reset under the action of gravity, the clamping portions extend into the lifting hole of the aluminum anode, then the abutting block moves into the gap and abuts against the clamps to limit the rotation of the two clamps in opposite directions, so that the aluminum anode is stably clamped, and the oil cylinder does not need to bear the load of the spring, so the service life of the oil cylinder is not shortened.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] Because the relevant technology requires the spring to be stretched before each time the anode clamp is lifted and placed, there is a technical problem that causes the hydraulic cylinder to bear excessive load, thereby shortening the life of the hydraulic cylinder.

[0034] To address the aforementioned technical problems, this application provides an aluminum electrolysis anode clamp for hoisting aluminum anodes, comprising a frame 1, clamps 2, and a lifting device 4.

[0035] Two clamps 2 are arranged symmetrically in mirror image and rotatably mounted on the frame 1. In this embodiment, the frame 1 also has two parallel fixed rods, and the clamps 2 are rotatably mounted on the fixed rods by means of bearings. A gap is formed between the two clamps 2 to prevent the two clamps 2 from abutting each other and causing motion interference when they rotate. A clamping part 3 is provided on one side of the clamp 2 opposite to the other clamp 2. The clamping part 3 has a first guide surface 31 facing downward. Specifically, the first guide surface 31 can be a slope or an arc surface. It can be understood that the first guide surface 31 should be a continuous and smooth surface.

[0036] The lifting device 4 includes a support block 41 movably mounted on the frame 1. The support block 41 has a movement path that moves into the gap. When the support block 41 moves into the gap, it can support the clamp 2 to restrict the two clamps 2 from rotating in opposite directions.

[0037] In the specific implementation process, the anode clamp is installed by the travelling crane or the overhead travelling crane, and after the anode clamp is hoisted to the position where the aluminum electrode is placed, the anode clamp is lowered, the clamping portions 3 on the two clamps 2 are in contact with the aluminum anode, and under the action of the first guide surface 31, the two clamps 2 are gradually separated, that is, rotate away from each other. With the continuous lowering of the anode clamp, the first guide surface 31 is not in contact with the aluminum anode, and under the action of gravity, the clamps 2 rotate and reset, and the clamping portions 3 extend into the hoisting hole of the aluminum anode, and then the abutting blocks 41 move into the gap and abut against the clamps, thereby limiting the rotation of the two clamps 2 away from each other, so that the aluminum anode is stably clamped, and the oil cylinder does not need to bear the load of the spring, so the service life of the oil cylinder is not shortened.

[0038] When the aluminum electrode is placed, the anode clamp is lowered so that the aluminum electrode is located in the electrolytic cell or another position, and then the abutting blocks 41 move and exit the gap, and with the continuous lowering of the anode clamp, the clamping portions 3 are separated from the hoisting hole on the aluminum electrode along the first guide surface 31. At this time, the travelling crane or the overhead travelling crane needs to be horizontally moved so that the clamping portions 3 are misaligned with the hoisting hole on the aluminum electrode, and then the travelling crane or the overhead travelling crane drives the anode clamp to rise, thereby completing the clamping and placing process of the entire aluminum electrode.

[0039] Referring to Figure 3 and Figure 4 , the clamp 2 comprises a rotating portion 21 rotatably arranged on the frame body 1, and the rotating portion 21 is rotatably arranged on the fixed rod through a bearing. The outer circumferential side wall of the rotating portion 21 has a protruding portion 21a, and when the abutting block 41 moves into the gap, the abutting block 41 can abut against the protruding portion 21a to limit the two protruding portions 21a from moving close to each other.

[0040] When the abutting block 41 does not move into the gap between the two clamps 2, the two clamps 2 can rotate away from each other, as shown in Figure 3 , and when the abutting block 41 moves into the gap between the two clamps 2, the abutting block 41 abuts against the protruding portion 21a, thereby limiting the rotation of the protruding portion 21a, and at this time, the two protruding portions 21 clamp the two sides of the abutting block 41 respectively, thereby ensuring uniform stress. Figure 4

[0041] The protruding portion 21a and the rotating portion 21 can be an integral structure or a split structure. In the embodiment of the present application, the protruding portion 21a and the rotating portion 21 can be an integral structure, and form an eccentric wheel structure with the fixed rod. It can be understood that the protruding portion 21a can also be a rod-shaped, block-shaped or other structure protruding from the rotating portion 21, as long as it can abut against the abutting block 41.

[0042] ​Further, the lower end of the clip 2 has a second guide surface 22 facing downward, which is a slope or an arc surface. It can be understood that the second guide surface 22 should be a continuous and smooth surface. The presence of the second guide surface 22 enlarges the distance between the lower ends of the two clips 2, facilitating the entry of the aluminum electrode between the two clips 2.

[0043] It can be understood that the upper end of the second guide surface 22 does not exceed the lower end of the first guide surface 31 in height, avoiding interference of the aluminum electrode when sliding from the second guide surface 22 to the first guide surface 31. Generally, the second guide surface 22 is in the same plane as the first guide surface 31, which can make the aluminum electrode transition smoothly from the second guide surface 22 to the first guide surface 31, and the guiding effect is better.

[0044] Further, the frame body 1 includes a horizontal plate 11 and side plates 12 located on both sides of the horizontal plate 11. The horizontal plate 11 and the side plates 12 can be an integral bending structure or a welded structure. The two side plates 12 are arranged along a first preset direction XX, and the two ends of the fixed rod are also connected to the two side plates 12. The two clips 2 are arranged along a second preset direction YY. The first preset direction XX and the second preset direction YY are parallel to the horizontal direction, and the first preset direction XX and the second preset direction YY are perpendicular to each other.

[0045] The rotating shaft is arranged between the two side plates 12 and at the lower end of the horizontal plate 11, which can also reduce dust in the space, especially dust in the first preset direction XX and dust falling under gravity into the rotating connection. In addition, since the first preset direction XX and the second preset direction YY are perpendicular to each other, the entire anode clamp is uniformly stressed, facilitating transportation.

[0046] On the basis of the previous embodiment, the lower end of each of the two side plates 12 is provided with a guide plate 13. From top to bottom, the distance between the two guide plates 13 gradually increases. The opposite side of the two guide plates 13 also plays a certain guiding role. The lower ends of the two guide plates 13 are far apart, facilitating the entry of the aluminum electrode between the two clips 2.

[0047] In order to prevent the side plates 12 from deforming, a reinforcing plate 14 is connected between the two side plates 12. The arrangement of the reinforcing plate 14 can greatly improve the strength of the frame body 1, ensuring the stability of the entire anode clamp.

[0048] In addition, the user can also weld a steel plate to the reinforcing plate 14 and the side plate 12 to further improve the stability of the entire frame body 1.

[0049] Further, the width of the reinforcing plate 14 in the second preset direction YY satisfies that when the two clamping parts 3 are in a horizontal state, that is, when the two clamps 2 are reset, the reinforcing plate 14 abuts against the clamp 2, so that the clamp 2 can be prevented from impacting the aluminum anode when reset under the action of gravity and external force, thereby playing a certain buffering role and protecting the aluminum anode.

[0050] It can be understood that the user can set a buffer layer, such as a sponge, rubber, and flexible material such as silica gel, on one side of the reinforcing plate 14 and the clamp 2 to absorb energy, which can further improve the buffering performance and reduce metal wear.

[0051] In some embodiments, the two clamps 2 are further connected with an elastic member 5, which can be a spring, an elastic rubber member, a leaf spring, or the like. In the present application, the elastic member 5 is preferably a spring, and the two ends of the spring are fixed on the clamp 2 by a fastener. The specific connection mode is a prior art, and will not be described in detail here.

[0052] The spring can provide a certain tension to facilitate the quick reset of the two clamps 2, and can also prevent the clamps 2 from shaking during hoisting and transportation, thereby ensuring stability.

[0053] In the present application, the lifting device 4 further comprises a hydraulic assembly 42, which is installed on the frame body 1 and connected with the abutting block 41. The hydraulic assembly 42 can bear a larger load and has higher stability.

[0054] In some embodiments, the lifting device 4 can also be a pneumatic cylinder.

[0055] In specific solutions, the hydraulic assembly 42 comprises a cylinder body 421, a piston rod 422, and a cover 423. The cylinder body 421 is installed on the cover 423, and the piston rod 422 is connected to the cylinder body 421 and connected with the abutting block 41. The piston rod 422 and the cylinder body 421 are commercially available products, and thus the specific connection relationship and working principle thereof will not be described in detail here.

[0056] The cover 423 is installed on the frame body 1 and encloses a channel with the frame body 1. The piston rod 422 penetrates the channel, and the piston rod 422 also penetrates the horizontal plate 11. It should be understood that the hole wall of the cover 423 and the horizontal plate 11 at the penetration position of the piston rod 422 is smooth, for example, coated, so as to reduce wear.

[0057] In the present application, the cover 423 can prevent the part of the piston rod 422 located in the channel from being contaminated by dust, and the piston rod 422 located at the lower end of the side plate 12 can also reduce contact with dust, especially dust falling from the air under the action of gravity, under the enclosure of the side plate 12 and the horizontal plate 11, thereby ensuring the normal use of the hydraulic assembly 42.

[0058] Based on the above embodiment, the dust in the external environment, especially the falling dust, can be reduced to pollute the piston rod in the hydraulic assembly, thereby affecting the normal use of the hydraulic assembly.
