Description

Technical Field

[0001] This utility model belongs to the technical field of slag removal devices, specifically relating to a slag removal device for the bottom of an electrolytic crane. Background Technology

[0002] Chinese patent application number 202221374143.5 discloses a multi-functional overhead crane slag removal device for electrolytic aluminum. The device is made by removing carbon slag. When in use, it is installed below the shell-breaking mechanism of the overhead crane. The tool cart can be started to push the carbon slag to both ends of the electrolytic cell, which is convenient for electrolysis workers to operate.

[0003] However, most existing electrolytic crane slag removal devices use grab buckets for operation. When the grab bucket is used for slag removal, because the slag trough is arranged at an angle and the grab bucket is raised and lowered vertically, the grab bucket can only handle the slag directly below it. As a result, the slag deep in the slag trough is difficult to handle, and the slag deep in the slag trough needs to be manually removed by the staff, which is not very practical. Utility Model Content

[0004] To address the problem of the inability to adjust the tilt angle of the grab bucket in the existing technology, this utility model provides a bottom slag removal device for an electrolytic crane. It employs a tilting mechanism combined with a slag removal mechanism to achieve the effect of removing slag from hard-to-reach areas deep within the slag tank. The specific technical solution is as follows: A bottom slag removal device for an electrolytic crane includes: a lifting mechanism, a rotating mechanism at the bottom of the lifting mechanism, a tilting mechanism at the bottom of the rotating mechanism, a first rotating shaft rotatably connected to the bottom of the tilting mechanism, and a slag removal mechanism at the bottom of the first rotating shaft; the tilting mechanism includes: a second housing, a second drive motor, a third rotating shaft, a second gear, and a third gear.

[0006] Preferably, both ends of the first rotating shaft extend rotatably out of the second housing, and connecting seats are fixedly installed at both ends of the first rotating shaft. A connecting member is fixedly installed at the bottom of the connecting seat, and a slag-removing mechanism is fixedly installed at the bottom of the connecting member.

[0007] Preferably, the rotating mechanism includes: a first housing, a connecting column, and a base plate. The first housing is fixedly installed at the bottom of the lifting mechanism. The connecting column is rotatably connected inside the first housing. The bottom of the connecting column extends rotatably out of the first housing. The base plate is fixedly installed at the bottom of the connecting column. The base plate is fixedly connected to the second housing.

[0008] Preferably, a gearbox is fixedly installed on the top of the first housing, a first drive motor is fixedly installed on one side of the gearbox, a second rotating shaft is provided at the output end of the gearbox, the second rotating shaft is arranged in a vertical direction, the bottom of the second rotating shaft extends rotatably into the first housing, the bottom of the second rotating shaft is rotatably connected to the inner bottom wall of the first housing, a first gear is fixedly fitted on the outer wall of the second rotating shaft, and a gear ring is fixedly fitted on the outer wall of the connecting column, the first gear meshing with the gear ring.

[0009] Preferably, the slag removal mechanism includes: a mounting shell, a first connecting shaft, a second connecting shaft, connecting arms, and grab buckets. The mounting shell is fixedly installed at the bottom of the connecting member. The first connecting shaft and the second connecting shaft are rotatably connected to both sides of the mounting shell, respectively. The first connecting shaft and the second connecting shaft are arranged in parallel. Both ends of the first connecting shaft and the second connecting shaft extend rotatably out of the mounting shell. Connecting arms are fixedly installed at both ends of the first connecting shaft and the second connecting shaft. Grab buckets are fixedly installed at the bottom of the two connecting arms on the same side. The two grab buckets are symmetrically arranged and adapted to each other.

[0010] Preferably, the surface of the grab bucket has openings.

[0011] Preferably, a first mounting base is fixedly fitted on the outer wall of the first connecting shaft, and a third mounting base is fixedly fitted on the outer wall of the second connecting shaft. A cylinder is hinged to the third mounting base, and an output shaft is provided at the output end of the cylinder.

[0015] The slag removal device for the bottom of the electrolytic crane of this utility model has the following advantages compared with the prior art:

[0016] 1. The slag removal device at the bottom of the electrolytic crane starts by starting the second drive motor, which drives the third shaft to rotate. The third shaft drives the second gear to mesh with the third gear, which in turn drives the first shaft to rotate. The first shaft drives the slag removal mechanism at the bottom to rotate, thereby changing the orientation of the working surface of the slag removal mechanism, making it easier to remove slag from parts that are difficult to reach.

[0017] 2. The bottom slag removal device for the electrolytic crane drives the second rotating shaft to rotate by starting the first drive motor. The second rotating shaft drives the first gear to mesh with the gear ring, which in turn drives the connecting column to rotate. This drives the bottom slag removal mechanism to rotate horizontally. Compared with most existing grab buckets that adjust their angle by rotating the top lifting part, resulting in an excessively long transmission distance, the device drives the rotation near the grab bucket, improving the overall stability of the device.

[0035] The lifting mechanism, first drive motor, second drive motor, grab bucket, and cylinder in this case are existing technologies.

As long as the lifting mechanism, first drive motor, second drive motor, grab bucket, and cylinder meet the requirements of this case, they are all acceptable and not limited to a single model.

[0036] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0037] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, the slag-removing mechanism 7 is lowered into the slag trough via the lifting mechanism 1. The rotating mechanism 2 and the tilting mechanism 3 are activated as needed. The first drive motor 23 is activated, and it drives the second rotating shaft 24 to rotate via the gearbox 22. The second rotating shaft 24 drives the first gear 25 to rotate. The gear 25 meshes with the toothed ring 26 and rotates, causing the toothed ring 26 to drive the connecting column 27 to rotate. The connecting column 27 then drives the grab bucket 75 of the slag-removing mechanism 7 to rotate to a suitable angle. By starting the second drive motor 32, the second drive motor 32 drives the third rotating shaft 33 to rotate. The third rotating shaft 33 drives the second gear 35 to rotate, causing the second gear 35 to mesh with the third gear 36 to rotate. The third gear 36 then drives the first rotating shaft 4 to rotate, thereby changing the tilt angle of the grab bucket 75, making it easier to use the grab bucket 75 to remove or grab slag deep in the slag trough.

[0038] When slag removal or grabbing is performed, the cylinder 710 is activated, which drives the output shaft 711 to move. The output shaft 711 pushes the first mounting seat 76, which drives the first connecting shaft 72 to rotate. Then, the fourth mounting seat 79 is moved through the connecting rod 712, which drives the second connecting shaft 73 to rotate in the opposite direction, so that the grab bucket 75 opens or closes to perform slag removal or grabbing operations.
