Description

Technical Field

[0001] The utility model relates to the field of aluminum electrolysis equipment, in particular to an aluminum electrolysis anode steel claw hanger. Background Art

[0002] Anode steel claws, also called electrolytic claws, are important conductive components in the electrolytic aluminum industry. The steel claws, aluminum guide rods, and anode carbon blocks together form the anode guide rod group, which connects the anode and transmits current.

[0003] The anode steel claw is the main component of the anode carbon block group, and the anode steel claw has to undergo multiple lifting during the processing and welding process. The traditional lifting method is to use a sling, but the sling is prone to wear after long-term use. When the wear is severe, the sling will cause it to break, posing a major safety hazard and increasing the danger of the staff during operation. Therefore, it is urgent to provide an anode steel claw lifting device to improve the lifting efficiency and eliminate safety hazards. Utility Model Content

[0004] The utility model provides an aluminum electrolytic anode steel claw lifting device, aiming to solve the problem that the sling is easily worn and damaged due to long-term friction between the sling and the steel claw during lifting, resulting in great safety hazards and low lifting efficiency.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] A steel claw hanger for an aluminum electrolytic anode includes a first connecting plate and a second connecting plate hinged to each other at the top ends, a first clamping plate hinged to the bottom end of the first connecting plate, and a second clamping plate hinged to the bottom end of the second connecting plate; the first clamping plate and the second clamping plate are hinged to each other in the middle, and positioning holes are symmetrically provided on the first clamping plate and the second clamping plate, and positioning pins are inserted into the positioning holes.

[0007] Preferably, a lifting lug is connected to the top end of the first connecting plate.

[0008] Preferably, the free ends of the first clamping plate and the second clamping plate are hook-shaped.

[0009] Preferably, the curvature of the hooks of the first clamping plate and the second clamping plate is the same as the curvature of the outer circumference of the anode steel claw.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The aluminum electrolysis anode steel claw lifting device provided by the utility model drives the first clamping plate and the second clamping plate to move together or apart synchronously through the first connecting plate and the second connecting plate, clamps or loosens the anode steel claw, and then combines with the lifting equipment to complete the lifting of the anode steel claw. The lifting process is safe and reliable, the lifting is stable, and the operation is convenient, which greatly improves the lifting efficiency and reduces the work intensity.

[0012] 2. The aluminum electrolytic anode steel claw sling provided by the utility model can be folded and stored by inserting a positioning pin into the positioning hole when not in the lifting state, which occupies a small space and is practical and convenient. Moreover, the whole material is steel, with a high reuse rate and a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] The utility model discloses an aluminum electrolysis anode steel claw lifting device, comprising a first connecting plate 1 and a second connecting plate 2 which are hinged to each other through bolts 6 at the top end, a lifting ear 9 is welded to the top end of the first connecting plate 1, a first clamping plate 3 is hinged to the bottom end of the first connecting plate 1 through bolts 6, and a second clamping plate 4 is hinged to the bottom end of the second connecting plate 2 through bolts 6, the free ends of the first clamping plate 3 and the second clamping plate 4 are in a hook shape, and the curvature of the hook is the same as the outer circumferential curvature of the anode steel claw 8, so as to facilitate clamping the anode steel claw 8 during lifting to prevent it from falling off; the middle parts of the first clamping plate 3 and the second clamping plate 4 are hinged to each other, and positioning holes 10 are symmetrically provided on the first clamping plate 3 and the second clamping plate 4, and positioning pins 5 are inserted into the positioning holes 10.

[0020] When using the lifting device of the present application to lift the anode steel claw 8, first insert the lifting hook of the lifting device into the lifting ear 9, lift the lifting device above the anode steel claw 8, then remove the positioning pin 5 so that the first clamping plate 3 and the second clamping plate 4 can move freely for clamping, check that the nut 7 on each bolt 6 is in a tightened state, and ensure the safety of the lifting operation. Then hook the hook ends of the first clamping plate 3 and the second clamping plate 4 on the anode steel claw 8 respectively, operate the lifting device to start lifting, at this time, the first connecting plate 1 and the second connecting plate 2 gradually approach each other, drive the first clamping plate 3 and the second clamping plate 4 to approach each other and clamp the anode steel claw 8 before lifting. After lifting the anode steel claw 8 to the clamping position, operate the lifting device to descend, the first connecting plate 1 and the second connecting plate 2 gradually depart from each other, drive the first clamping plate 3 and the second clamping plate 4 to depart from each other and release the anode steel claw 8, and complete the lifting of the anode steel claw 8. After the lifting is completed, insert the positioning pin 5 into any positioning hole 10, and store the lifting device for next use.
