Description

Technical Field

[0001] This utility model relates to the field of anode guide rod straightening devices, and more particularly to an offline anode guide rod straightening device. Background Technology

[0002] The anode guide rod is a crucial component in electrolytic aluminum production, primarily used to connect the anode and the electrolytic cell, ensuring smooth current flow and thus completing the aluminum production process. When an offline anode guide rod becomes bent, it cannot be corrected online, leading to accumulation in the anode storage area. For offline anodes, the only solution for a bent guide rod is to cut it open at the point of explosion, replace it with a new one, and then manually weld it. Due to the lack of specialized equipment, this involves erecting a scaffold, using a hand-operated hoist to lift the new guide rod, and manually leveling and welding it. This results in high operational difficulty, a large welding workload, and low repair efficiency. Therefore, developing an offline anode guide rod straightening device is a pressing issue for those skilled in the art. Utility Model Content

[0003] The purpose of this invention is to provide an offline anode guide rod straightening device, which solves the problem that existing straightening devices do not have offline anode guide rods and are difficult to repair manually.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses an offline anode guide rod straightening device, comprising a straightening device fixing bracket, an electric hoist body, and a hydraulic straightening mechanism. An electric hoist track is fixedly mounted on the straightening device fixing bracket. The electric hoist body is movably mounted on the electric hoist track. A hydraulic straightening mechanism is mounted on the lower end of the electric hoist body via a hook. The hydraulic straightening mechanism includes a bearing beam and a separate hydraulic jack. The separate hydraulic jack is mounted on the front end face of the bearing beam, and a straightening device clamping arm that cooperates with the guide rod of the defective anode group is mounted on the front end face of the bearing beam.

[0006] Furthermore, the clamping arm of the straightening device mates with the left and right end faces of the guide rod of the defective anode group, and the clamping arm of the straightening device is detachably provided with a clamping arm pin that mates with the front end face of the guide rod of the defective anode group.

[0007] Furthermore, the bottom end of the defect anode group is mounted on a rotating bracket, which is rotatably mounted on the straightening device's fixed bracket.

[0008] Furthermore, the bottom end of the electric hoist bracket is welded to the straightening device fixing bracket, and the electric hoist track is welded to the electric hoist bracket.

[0009] Furthermore, the top of the hydraulic straightening mechanism is welded with a lifting lug that cooperates with the electric hoist body.

[0010] Furthermore, the rotating bracket is rotatably mounted on the straightening device fixed bracket via a large gear. The straightening device fixed bracket is equipped with a drive motor and a worm gear reducer. The output shaft of the drive motor is connected to the worm gear reducer, and the worm gear reducer is equipped with a small gear that meshes with the large gear.

[0011] Furthermore, a laser rangefinder sensor that cooperates with the guide rod of the defect anode group is provided on the front end face of the supporting beam.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model relates to an offline anode guide rod straightening device, which includes a rotating bracket for supporting defective anode groups. The rotating bracket is rotatably mounted on the fixed bracket of the straightening device, facilitating adjustment of the angle of the defective anode groups.
