Description

Technical Field

[0001] This utility model belongs to the technical field of lifting equipment and relates to an anode guide rod lifting device with self-locking function. Background Technology

[0002] In the production of primary aluminum electrolysis, electrolytic anodes are required. These anodes mainly consist of two parts: a carbon block and an anode guide rod. The anode guide rod itself can be composed of an aluminum guide rod, a composite block, and steel claws. As a key component of the anode guide rod, the aluminum guide rod's working surface is pressed into contact with the anode balance busbar via a small clamp, guiding direct current into the anode carbon block and thus providing conductivity. In practice, due to prolonged use, the steel claws and composite block of the aluminum guide rod often suffer varying degrees of damage, necessitating repair. The main steps for repairing the aluminum guide rod are: using a lifting device to hoist the aluminum guide rod to its designated location; and after repair, using the same device to hoist it back to its original position. Therefore, the lifting device is an indispensable tool in the aluminum guide rod repair process. In actual production, aluminum guide rods are arranged in rows with small gaps. When using flat lifting straps or ropes to lift aluminum guide rods, operators must first use a crowbar to pry open a certain gap before lowering the lifting straps or ropes for binding. Using flat lifting straps or ropes to lift angular guide rods is prone to wear and breakage. In addition, the ropes may loosen or slip during the lifting process, causing the guide rods to fall and causing safety accidents. This results in low lifting and repair efficiency and cannot meet the actual production needs.

[0003] In summary, the existing technology has the problem that the anode guide rod used in electrolytic aluminum is prone to slipping during the hoisting process. Utility Model Content

[0004] The purpose of this invention is to provide an anode guide rod lifting device with a self-locking function, which solves the problem of easy slippage of the anode guide rod used in electrolytic aluminum during the lifting process in the prior art.

[0005] The technical solution adopted by this utility model is an anode guide rod lifting device with self-locking function, including a main frame. The main frame structure is "L" shaped. One end of the main frame is connected to the lifting ring through a chain. The main frame and the chain are equipped with positioning devices.

[0006] The features of this utility model also include:

[0007] The lifting ring includes a main board with a square opening. A first connecting plate is vertically attached to both sides of one end of the main board, and a second detachable chain link is connected to the first connecting plate.

[0008] The positioning device has a U-shaped structure and is designed to work in conjunction with the aluminum guide rod of the anode guide rod. The positioning device includes a positioning plate, one side of which is connected to the main frame, and the other two ends of which are vertically connected to limit plates.

[0009] The limiting plates are positioned opposite each other, and a second connecting plate is vertically attached to the outer wall of the limiting plate on the side away from the positioning plate. A first detachable chain link is connected to the second connecting plate.

[0010] The first detachable link and the second detachable link are connected by a chain.

[0011] The end of the limiting plate away from the positioning plate is provided with a connecting hole, which is set opposite to the positioning plate; the connecting hole is configured to cooperate with the limiting pin.

[0012] The two ends of the limit pin are connected to the connecting holes on the positioning plate, respectively.

[0013] The main frame includes an upright plate, one end of which is connected to a positioning plate. An upper handle is connected to the side wall of the upright plate on the side away from the positioning plate.

[0014] A clamping plate is connected to the end of the upright plate away from the positioning plate. A lower handle is connected to one side wall of the clamping plate, and a notch is provided on the other side wall of the clamping plate. The notch is designed to match the shape of the steel claw of the anode guide rod.

[0015] On the side wall of the card plate with a notch, one end of the bottom plate is vertically connected to the end away from the upright plate. On the other end of the bottom plate, a limit protrusion is provided on the side wall of the side wall near the upright plate.

[0016] The card plate, base plate, and steel claw beam of the anode guide rod are fitted together.

[0017] The beneficial effects of this utility model are: when used for hoisting, it can be locked with the anode guide rod used for electrolytic aluminum, which can effectively prevent the anode guide rod from falling off during the hoisting process, improve the hoisting efficiency, and eliminate safety hazards; this hoisting device has a compact structure and reasonable design.
