Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum electrolytic cell clamping technology, and in particular to a clamping frame for an aluminum electrolytic cell. Background Technology
[0002] The goal is to ensure that the current on the anode guide rod is smoothly introduced into the anode, that the contact voltage drop between the anode guide rod and the aluminum frame is stable and low, that the clamping frame can reliably clamp and lift the anode, that the height of the anode remains stable when the clamping frame is raised and lowered, that the anode can be raised and lowered when the clamping frame is in a fixed position, and that the clamping frame lifting operation is reliable and efficient.
[0003] Existing clamping frames for aluminum electrolytic cells often employ a type of feeding fixture for aluminum profile anodizing, as disclosed in CN210215582U. This fixture has a clamping frame between a first fixed post and a second fixed post, with a second fixed frame fixedly connected to the middle of one side of the clamping frame. A second servo motor is fixedly connected inside the second fixed frame. A first rubber pad is provided on one side of the inside of the clamping frame, and a movable plate is provided inside the clamping frame. A second rubber pad is provided on the side of the movable plate closest to the first rubber pad. This fixture can clamp and fix the aluminum profile, and its operation is simple. However, using a single type of fixed frame to support and clamp the aluminum electrolytic cell in a single direction easily leads to a lack of stress support. This not only makes it prone to tilting due to force imbalance, but also makes it difficult to provide sufficient support for the aluminum electrolytic cell under the influence of gravity, easily causing the aluminum electrolytic cell to fall vertically. Utility Model Content
[0004] The purpose of this utility model is to solve the problem of difficulty in clamping and fixing aluminum electrolytic cells in the prior art, and to propose a clamping frame for aluminum electrolytic cells.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A clamping frame for an aluminum electrolytic cell includes a lifting plate. A drive motor is fixedly installed at the center of the lifting plate. Limiting clamps corresponding to the outer wall of the aluminum electrolytic cell are provided on both the front and rear sides of the lifting plate. A first traction mechanism driven by the drive motor and used to move and pull the limiting clamps to clamp the aluminum electrolytic cell in opposite directions is provided on the lifting plate. A tensioning support plate supporting the aluminum electrolytic cell from bottom to top is installed on the limiting clamp. A second traction mechanism is provided on the limiting clamp for driving the tensioning support plate to deflect 90°.
[0007] Preferably, the first traction mechanism includes a traction rod keyed to the output end of the drive motor, a guide block slidably installed in the hoisting plate and movably pulled by the traction rod, a swing arm with a limit clamping plate movably pulled by the guide block and rotatably installed on the hoisting plate, and a steering component for adjusting the limit clamping plate toward the outer wall of the aluminum electrolysis cell is provided on the swing arm.
[0008] Preferably, a first pull rod is pinned between the traction rod and the guide block, and a second pull rod is pinned between the guide block and the opening / closing swing rod.
[0009] Preferably, the steering assembly includes a first drive cylinder mounted on a tensioning rocker arm with a pin shaft, a drive rack slidably mounted on the tensioning rocker arm and connected to the output pin shaft of the first drive cylinder, and a driven gear meshing with the drive rack is keyed to the limiting clamp plate.
[0010] Preferably, the second traction mechanism includes a second drive cylinder fixedly installed on the limiting clamp, a lifting rack slidably installed in the limiting clamp and fixedly connected to the output end of the second drive cylinder, and an incomplete gear integrally connected to one end of the opening and closing support plate and meshing with the lifting rack.
[0011] Preferably, the limiting clamp has a storage groove for setting the opening and closing support plate.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. This utility model utilizes a lifting plate with symmetrically distributed limiting clamps at the front and rear, and the opening and closing swing rod is driven by a drive motor to swing open and close. At the same time, a steering component is provided on the opening and closing swing rod to adjust the angle of the limiting clamps. The limiting clamps can clamp the aluminum electrolytic cell from the front and rear sides by meshing transmission between the drive rack and the driven gear.
[0014] 2. The present invention provides a tensioning support plate that can be deflected 90° in the storage groove of the limiting clamping plate. By setting a lifting rack and an incomplete gear that are meshed together, the tensioning support plate can be driven to support the aluminum electrolysis cell from bottom to top in a horizontal state.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-5 A clamping frame for an aluminum electrolytic cell includes a lifting plate 1, which can be connected to a crane to facilitate the stable lifting of the aluminum electrolytic cell by the crane. A drive motor 2 is fixedly installed at the center of the lifting plate 1. Limiting clamps 3 corresponding to the outer wall of the aluminum electrolytic cell are provided on both the front and rear sides of the lifting plate 1. It should be noted that by setting the limiting clamps 3 that abut against the outer wall of the aluminum electrolytic cell, the aluminum electrolytic cell is clamped from the horizontal direction to prevent the aluminum electrolytic cell from tilting due to imbalance of force.
[0023] The lifting plate 1 is equipped with a first traction mechanism 4, which is driven by a drive motor 2 and used to clamp the aluminum electrolysis cell with opposing traction limiting clamps 3. See the attached instruction manual for details. Figure 1 Appendix Figure 3 With appendix Figure 4 The first traction mechanism 4 includes a traction rod 41 keyed to the output end of the drive motor 2. A guide block 42, which is movably pulled by the traction rod 41, is slidably installed in the hoisting plate 1. A tensioning swing rod 43, which is movably pulled by the guide block 42 and rotates to install the limiting clamping plate 3, is pin-mounted on the hoisting plate 1. It should be noted that the distance between the limiting clamping plate 3 and the outer wall of the aluminum electrolytic cell is adjusted by driving the tensioning swing rod 43 to adjust the tensioning swing, so as to clamp and fix different aluminum electrolytic cells with different sizes. The tensioning swing rod 43 is provided with a steering component 46 for adjusting the orientation of the limiting clamping plate 3 toward the outer wall of the aluminum electrolytic cell.
[0024] To further explain, the steering assembly 46 includes a first drive cylinder 461 with a pin mounted on the opening and closing swing arm 43. A drive rack 462, which is connected to the output pin of the first drive cylinder 461, is slidably mounted on the opening and closing swing arm 43. A driven gear 463, which meshes with the drive rack 462, is keyed to the limiting clamp 3. It should be noted that because the limiting clamp 3 deflects with the opening and closing swing arm 43, in order to ensure that the limiting clamp 3 and the outer wall of the aluminum electrolysis cell can fit and abut, the angle of the limiting clamp 3 is adjusted to ensure that the two can fit together.
[0025] The limiting clamp 3 has a pin on which a tensioning support plate 5 supporting the aluminum electrolysis cell is mounted from bottom to top. The limiting clamp 3 is provided with a second traction mechanism 6 for driving the tensioning support plate 5 to deflect 90°. For details, please refer to the appendix of the instruction manual. Figure 2 With appendix Figure 4 The second traction mechanism 6 includes a second drive cylinder 61 fixedly installed on the limiting clamp 3. A lifting rack 62 fixedly connected to the output end of the second drive cylinder 61 is slidably installed in the limiting clamp 3. One end of the tensioning support plate 5 is integrally connected to an incomplete gear 63 that meshes with the lifting rack 62. It should be noted that the limiting clamp 3 has a receiving groove for setting the tensioning support plate 5. Because the receiving groove guides and limits the tensioning support plate 5, the tensioning support plate 5 deflected from the receiving groove can only rotate to a horizontal state at most, ensuring that it supports the aluminum electrolysis cell in a horizontal state.
[0026] A first pull rod 44 is pin-connected between the traction rod 41 and the guide block 42, and a second pull rod 45 is pin-connected between the guide block 42 and the opening and closing swing rod 43. The traction rod 41 is eccentrically set, and during its rotation, it generates a horizontal position difference, which supports the guide block 42 to move in the hoisting plate 1, and then drives the opening and closing swing rod 43 to deflect through the second pull rod 45.
[0027] It should be noted that the specific models and specifications of the drive motor 2, the first drive cylinder 461, and the second drive cylinder 61 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be elaborated here.
[0028] The functional principle of this utility model can be explained through the following operation methods:
[0029] The second drive cylinder 61 is opened by controlling the limit clamping plate 3, so that the lifting rack 62 moves upward, and the tensioning support plate 5 tends to deflect horizontally through the incomplete gear 63, and then the aluminum electrolysis tank is placed on the tensioning support plate 5.
[0030] When the drive motor 2 is turned on, the output end of the drive motor 2 drives the traction rod 41 to deflect. The traction rod 41 pulls the guide block 42 to move linearly through the first pull rod 44. The guide block 42 pulls the opening and closing swing rod 43 to move through the second pull rod 45, so that the limiting clamps 3 on the front and rear sides drive the opening and closing support plate 5 to deflect towards the aluminum electrolysis cell.
[0031] The first drive cylinder 461 is opened by controlling the opening and closing swing arm 43. The first drive cylinder 461 drives the drive rack 462 to move, and drives the limit clamp 3 to deflect through the driven gear 463 until the limit clamp 3 contacts the outer wall of the aluminum electrolysis cell.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
