[0028] Example 1

[0029] like Figure 1 As shown, an anode clamp for aluminum electrolysis overhead crane operation is disclosed, the anode clamp includes a mounting frame 101 connected to the overhead crane, a telescopic cylinder 102 arranged on the mounting frame 101, and a support rod 105 arranged on the mounting frame 101 and parallel to the telescopic cylinder 102; the anode clamp also includes a lifting plate 103, the middle part of the lifting plate 103 is hinged to the end of the support rod 105, one end of the lifting plate 103 is connected to the telescopic end of the telescopic cylinder 102; the lifting plate 103 can rotate around the end of the support rod 105 under the action of the telescopic cylinder 102.

[0030] In this embodiment, the anti-slip mechanism of the small box clamp is replaced. Specifically, it includes a mounting frame 101 connected to the overhead crane, and the mounting frame 101 is specifically installed at the bottom end of the Z axis of the overhead crane. A telescopic cylinder 102 is arranged on the mounting frame 101. The telescopic end of the telescopic cylinder 102 is connected to the lifting plate 103. The lifting plate 103 is also hinged to the bottom of the support rod 105. Specifically, the lifting plate 103 can be set to a bent shape, and the bending point of the lifting plate 103 is hinged to the support rod 105. When the telescopic cylinder 102 is started, the lifting plate 103 will be driven to rotate relative to the mounting frame 101. Under the action of the telescopic cylinder 102, the end of the lifting plate 103 away from the telescopic cylinder 102 will rotate around the end of the support rod 105 to the bottom of the small box clamp on the anode guide rod, thereby supporting the lower end of the small box clamp. Finally, the upper and lower ends of the small box clamp are supported, thereby ensuring the stability of the small box clamp.

[0031] Specifically, the lifting plate 103 is connected to the telescopic cylinder 102 via a pin shaft.

[0032] In this embodiment, a position sensor 104 can also be provided on the mounting bracket 101. When the lifting plate 103 contacts the bottom of the small box fixture, the position sensor 104 will transmit a position signal, and thus the telescopic oil cylinder 102 will stop moving. By providing the position sensor 104, it is avoided that after the lifting plate 103 contacts the bottom of the small box fixture, the telescopic oil cylinder 102 continues to operate and damages the small box fixture.

[0033] Embodiment 2

[0034] As Figures 2 to 3 shown, an anode fixture for an aluminum electrolysis crane operation is disclosed. The anode fixture includes a mounting bracket 101 connected to the crane, a telescopic oil cylinder 102 provided on the mounting bracket 101, and a support rod 105 provided on the mounting bracket 101 and arranged in parallel with the telescopic oil cylinder 102; the anode fixture further includes a lifting plate 103, the middle of the lifting plate 103 is hinged to the end of the support rod 105, and one end of the lifting plate 103 is connected to the telescopic end of the telescopic oil cylinder 102; the lifting plate 103 can rotate around the end of the support rod 105 under the action of the telescopic oil cylinder 102.

[0035] The difference between this embodiment and Embodiment 1 is that: the anode fixture further includes a head frame 1, a guide plate 2 and an opening and closing device. The head frame 1 includes a top plate 11 and two mounting side plates 12 installed at the lower end of the top plate 11. The guide plate 2 includes a guide plate body 21 and a connecting piece one 24 provided on the guide plate body 21; a connecting piece two 13 protrudes from the outer wall of the side plate 12, and the connecting piece two 13 is rotationally connected to the connecting piece one 24; the hinge shaft portion formed by the connecting piece one 24 and the connecting piece two 13 supports the guide plate to adjust the distance between the top or bottom of the guide plate 2 and the side plate 12. The opening and closing device includes clips 3 located on both sides of the side plate 12 and an adjusting device connected to the clips 3 and driving the clamping ends of the clips 3 to open and close; the adjusting device is installed on the inner wall of the side plate 12.

[0036] The clip 3 is installed at the lower end of the top plate 11. The clip 3 includes a mounting end connected to the lower end of the top of the head frame 1 and a clamping end away from the top of the head frame 1. A travel switch 4 is provided on one side of the mounting end, and a proximity switch 5 is installed at the lower end of the top of the head frame 1. The opening of the clamping end of the clip 3 and the bottom end of the head frame 1 enclose a space for placing the anode guide rod. In order to ensure that the anode fixture meets the requirements of intelligence, a travel switch 4 is provided. The travel switch 4 can effectively sense the opening and closing state of the clip 3, so as to accurately judge and adjust the further actions of the entire crane. At the same time, the installation of the proximity switch 5 is used to sense whether it is close to the anode guide rod, making the entire fixture more accurate and controllable. The travel switch 4 and the proximity switch 5 can both be selected from the commonly used models in the art, which are convenient to install and have low costs.

[0037] And to meet the requirements of intelligent use, the adjusting device includes a spring device 7 and a driving part for driving the clamp 3 to rotate. The driving part preferably uses an oil cylinder 6, and the oil cylinder 6 is a double-acting oil cylinder; both ends of the spring device 7 are fixedly connected to the inner wall of the clamp 3, or both ends of the spring device 7 are connected with connecting rods, and the spring device 7 is connected to the inner wall of the clamp 3 through the connecting rods; the oil cylinder 6 is connected to the side wall of the clamp 3. When the oil cylinder 6 does work, the oil cylinder 6 will push the clamping end of the clamp 3 to gradually move away from the center of the headstock 1, so as to increase the clamping opening size of the clamp 3. When the oil cylinder 6 pushes the clamp 3 to open, the spring device 7 is in a stretched state. When the anode guide rod is completely within the clamping range of the clamp, the oil cylinder 6 is closed. At this time, under the action of the spring restoring force of the spring device 7, the clamping ends of the clamp 3 will gradually close, so as to clamp the anode guide rod from both ends.

[0038] When it is necessary to clamp the anode guide rod, through the action of the oil cylinder 6, the clamping ends of the clamp 3 are moved away from each other, so as to increase the clamping opening size of the clamp 3, so as to facilitate the insertion of the anode guide rod. At this time, the spring is in a stretched state. When the anode guide rod is inserted into the inside of the clamp 3, the oil cylinder 6 is turned off, and the clamping ends of the clamp 3 approach each other under the action of the spring, so as to clamp the anode guide rod.

[0039] By designing the oil cylinder 6 and the spring device, correspondingly controlling the opening and closing of the clamping ends of the clamp 3, the clamping opening size of the clamp 3 is effectively increased, which facilitates the clamping of the anode guide rail by this fixture and improves the clamping efficiency.

[0040] The installation parts of the two clamps 3 are partially fitted together. In order to ensure that the left and right symmetrically designed clamps 3 can move synchronously during the opening or closing process of the clamp 3, sawteeth can be provided on the installation parts of the clamps 3, and the installation parts of the two clamps 3 are connected by meshing. Through the meshing connection, when the clamping parts of the clamp 3 are opening or closing, the two clamps 3 can move synchronously, enhancing the stability of the movement of the clamp 3.

[0041] In order to make it easy for the anode guide rod to be inserted into the accommodation space formed by the clamp 3 and the side plate 12 and to prevent the bottom of the guide plate 2 from hindering the normal insertion of the anode guide rod, a baffle portion 22 can be provided at the top end of the guide plate 2. The width of the baffle portion 22 in the horizontal direction is smaller than the total width of the connecting member 1 24 and the connecting member 2 13 in the horizontal direction. The baffle portion 22 can specifically be a long strip in a certain direction. When the anode structure is to be operated, an external force will be applied to the top of the guide plate 2. At this time, the baffle portion 22 on the top of the guide plate 2 close to the top plate will closely abut against the side plate 12. Then, under the action of the hinge portion formed by the connecting member 1 and the connecting member 2, the bottom of the guide plate 2 will move away from the side plate 12, thus preventing the bottom of the guide plate 2 from affecting the insertion of the anode guide rod. After the anode guide rod is completely inserted into the clamping area of the lower clamp 3, the original external force applied to the top of the guide plate 2 will gradually move along the direction of the guide plate to the bottom of the guide plate 2. When the external force is between the hinge portion and the bottom of the guide plate 2, the bottom of the guide plate 2 will gradually approach the side plate 12 and finally close to the surface of the anode guide rod. At the same time, the bottom end of the guide plate 2 is inclined towards the direction where the side plate 12 is located, so that when the bottom end of the guide plate moves towards the side, the bottom end of the guide plate can better fit the anode guide rod.

[0042] A visual sensor marker for the visual sensor 8 to identify and confirm the position of the fixture is provided on the side plate 12.

[0043] In summary, the two clamps 3 and the side plate form a clamping area for clamping the anode guide rod. Before the anode guide rod is inserted, the distance between the bottoms of the two clamps 3 is adjusted by the adjusting device. At the same time, under the hinge action, the bottom of the side plate is also away from the guide plate, thus greatly increasing the clamping size of the clamping area and making it extremely easy for the anode guide rod to be inserted. That is, in this embodiment, the size of the clamping area can be flexibly adjusted and controlled. So when this anode fixture needs to clamp the anode guide rod, the size of the clamping area is enlarged in advance, which is convenient for the anode guide rail to be inserted, greatly improving the efficiency of this fixture for clamping the anode guide rod. At the same time, the whole fixture is intelligent, precise and highly controllable, making the anode fixture applicable to different anode guide rods, with good clamping effect, no phenomenon such as block dropping, and high safety performance.

[0044] The anode fixture further includes a wrench component, and the guide roller of the wrench component acts above the guide plate at the connecting member 1 24 and the pin 25.

[0046] Disclosed is an anode fixture for an aluminum electrolysis crane operation. The anode fixture includes a mounting frame 101 connected to the crane, a telescopic oil cylinder 102 provided on the mounting frame 101, and a lifting plate 103 hinged to the bottom of the mounting frame 101; one end of the lifting plate 103 away from the small box fixture is connected to the telescopic end of the telescopic oil cylinder 102.

[0047] The difference between this embodiment and the above-mentioned embodiment lies in that this anode fixture is communicatively connected to the background control terminal by the overhead crane, thereby realizing automated operation.
