Description

Technical Field

[0001] This utility model relates to the field of lifting and cleaning support technology, specifically to a lifting and cleaning support for aluminum electrolytic cells. Background Technology

[0002] In the aluminum electrolysis production process, the ladle tube is a key piece of equipment for transporting high-temperature electrolytes. Each time aluminum is tapped, the electrolyte and molten aluminum have a solidified layer of varying degrees on the wall of the ladle tube. Therefore, the wall of the ladle tube needs to be cleaned every shift to ensure the smooth operation of aluminum tapping.

[0003] Currently, cleaning often requires suspending the bale tube and manually operating tools to remove the solidified layer. However, the suspended bale tube is prone to horizontal and vertical swaying under stress, which not only makes the cleaning operation difficult and affects efficiency but also poses serious safety hazards. Existing support and fixing devices are relatively simple in structure, such as a simple combination of a base, support rod, and bale tube clamp, and therefore generally suffer from insufficient clamping stability. They are particularly difficult to adapt to bale tubes from different batches and with different inclination angles, resulting in poor versatility.

[0004] To address this, we propose a support for cleaning the aluminum electrolytic cell's lifting tube. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cleaning support for the lifting tube of an aluminum electrolysis cell.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cleaning support for lifting and cleaning aluminum electrolytic cell tubing, comprising: Base; Two support plates are symmetrically fixed to the base; An electric motor is fixedly attached to one of the side walls of the support plate; A bidirectional lead screw, which rotates through two support plates, and the sidewalls of the bidirectional lead screw are symmetrically threaded with sliders; A limiting plate is fixed between the two support plates, and the slider slides against the limiting plate; A connecting plate fixed to the bottom wall of each slider; The connecting plate is connected to a connecting frame through an adjustment mechanism. One end of the connecting frame is fixed to a base plate through a connecting rod. Semi-circular ring clamps are symmetrically fixed to the side wall of the base plate.

[0007] Preferably, the adjustment mechanism includes: A rotating shaft is rotatably connected to the inner wall of the connecting plate. The connecting frame and the side wall of the rotating shaft are fixedly connected.

[0008] Preferably, the adjustment mechanism further includes: Symmetrical circular holes are formed on the side wall of the connecting frame; Multiple through holes are formed along a circular array on the sidewall of the connecting plate; And limit bolts and nuts.

[0009] Preferably, the limiting bolt passes through a round hole, a through hole, and another round hole in sequence, and the limiting bolt is threadedly connected to the nut.

[0010] Preferably, a buffer pad is fixed to the inner sidewall of the semi-circular ring clamp.

[0011] Preferably, the motor is a reversible motor.

[0012] Preferably, the output end of the motor and the bidirectional lead screw are fixed coaxially.

[0013] This utility model has the following beneficial effects: 1. A motor drives a bidirectional lead screw, which in turn drives two sets of sliders to move synchronously in opposite directions, thereby causing two pairs of semi-circular ring clamps to clamp the tube from different positions. This symmetrical clamping structure forms a stable multi-point constraint, which can effectively suppress the horizontal swaying and vertical movement that may occur during the cleaning process, greatly improving the stability and safety of the operation. 2. This utility model allows operators to quickly and conveniently adjust the tilt angle of the semi-circular ring clamp, enabling it to accurately adapt to different batches and different tilt angles of the lifting tubes, significantly improving the applicability and economic benefits of the cleaning support. 3. The base has sufficient self-weight, providing overall stability. The inner side of the semi-circular clamping plate is equipped with a rubber buffer pad, which provides sufficient clamping force while avoiding scratches or indentations on the pipe surface caused by rigid clamping, thus playing a good protective role.

[0016] 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.

[0017] Reference Figures 1-3 A support bracket for cleaning aluminum electrolytic cell tubing, comprising: Base 1 has a certain weight and is not easily tipped over; Two support plates 2 are symmetrically fixed to the base 1; Motor 3 is fixed to the side wall of one of the support plates 2. Motor 3 is a forward and reverse reversible motor, and the rotation direction of the output shaft of motor 3 is controllable. Specifically, by changing the direction of the current input to motor 3 or controlling its wiring method, the bidirectional lead screw 4 can be driven to rotate in the forward or reverse direction. The bidirectional lead screw 4 rotates through two support plates 2, and the side wall of the bidirectional lead screw 4 is symmetrically threaded with sliders 5. The output end of the motor 3 is coaxially fixed with the bidirectional lead screw 4. The limiting plate 6 is fixed between the two support plates 2, and the slider 5 slides against the limiting plate 6, so that the slider 5 will not rotate. A connecting plate 7 is fixed to the bottom wall of each slider 5; one end of the connecting plate 7 has a convex structure, and a connecting frame 8 is connected inside the connecting plate 7 through an adjustment mechanism. The end of the connecting frame 8 near the connecting plate 7 has a concave structure, and one end of the connecting frame 8 is fixed to the bottom plate 9 through a connecting rod 17. Semicircular ring clamps 10 are symmetrically fixed to the side wall of the bottom plate 9.

[0018] The adjustment mechanism includes: a rotating shaft 11, which is rotatably connected to the inner wall of the connecting plate 7; and a connecting frame 8 which is fixedly connected to the side wall of the rotating shaft 11.

[0019] The adjustment mechanism also includes: symmetrically arranged circular holes 12 on the side walls of the connecting frame 8; multiple through holes 13 arranged in a circular array on the side walls of the connecting plate 7. If the production workshop uses three lifting pipes with different inclination angles, then the number of through holes 13 is set to three accordingly, and after each through hole 13 passes through the connecting limiting bolt 14, the semi-circular ring clamp 10 can be used with a lifting pipe of one inclination angle; and limiting bolt 14 and nut 15. The limiting bolt 14 passes through the circular hole 12, the through hole 13 and another circular hole 12 in sequence, and the limiting bolt 14 is threadedly connected to the nut 15.

[0020] A buffer pad 16 is fixed to the inner wall of the semi-circular ring clamp 10. The buffer pad 16 is made of high-temperature resistant rubber material and can play a protective role through deformation.

[0021] In this invention, the cleaning bracket is first moved to the position of the suspended lifting pipe, and the motor 3 is started. The motor output drives the bidirectional lead screw 4 to rotate, causing the two sliders 5 to move towards each other along the lead screw axis. Each slider 5 drives the connecting plate 7 fixed to it to move synchronously, and then indirectly through the connecting frame 8, the semi-circular ring clamps 10 move closer to each other until they clamp the side wall of the lifting pipe. By using two sets of symmetrically arranged semi-circular ring clamps 10 to clamp the lifting pipe at two positions simultaneously, the swaying in the horizontal and vertical directions is effectively limited, improving clamping stability.

[0022] When it is necessary to adapt to different batches of lifting pipes (whose tilt angles may differ, but are still fixed), the angle of the semi-circular clamp 10 can be adjusted. The specific operation is as follows: First, unscrew the nut 15, pull out the limiting bolt 14, then support the base plate 9 and rotate the connecting frame 8 by the corresponding angle, aligning the round hole 12 with another through hole 13. Reinsert the limiting bolt 14 and pass it through both round holes 12 and the corresponding through hole 13 in sequence. Finally, tighten the nut 15 to complete the angle adjustment and fixation. Repeating the aforementioned clamping steps allows for adaptation to lifting pipes with different tilt angles, facilitating subsequent cleaning operations.

[0023] 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.
