Description

Technical Field:

[0001] The utility model relates to the technical field of cathode carbon block equipment, and particularly relates to a special fixture for cathode carbon blocks. Background Art:

[0002] Cathode carbon blocks refer to carbon blocks made of high-quality anthracite, coke, graphite, etc.; they are used as the cathodes of aluminum electrolysis cells. Cathode carbon blocks are usually rectangular parallelepipeds. According to the number of assembled cathode steel bars, a corresponding number of rectangular grooves are usually opened on the surface. The cathode steel bars can be assembled in the rectangular grooves by using the pig casting method, the carbon paste ramming method, or the bonding method.

[0003] During the handling of cathode carbon blocks, a fixture is required. The fixture clamps and fixes the opposite two side surfaces of the cathode carbon block by using friction. However, due to the long-term use of the fixture, the surfaces for clamping will be worn, resulting in a gradual decrease in the friction generated during clamping, and there is a phenomenon of accidental detachment. Therefore, there is a potential danger, and a new technical solution needs to be proposed to solve the defects existing in the current prior art. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a special fixture for cathode carbon blocks to solve the problems raised in the above background art.

[0005] The utility model is implemented by the following technical solutions:

[0006] A special fixture for cathode carbon blocks includes a protective frame, two brackets, a cross beam, and four chain hooks; both ends of the protective frame in the length direction are respectively sleeved with brackets. One side edge of the bottom of the bracket is attached to the upper surface of the support plate. The cross beam is located above the two brackets, and the lower surface of the cross beam is connected to four through holes on the two brackets through four chain hooks respectively.

[0007] Preferably, the protective frame includes two support frames, and the tops of the two support frames are fixedly connected by two square steel bars.

[0008] Preferably, each support frame includes an upper steel plate, a lower steel plate, and two support plates. Two support plates are symmetrically and fixedly arranged between the upper steel plate and the lower steel plate. The tops of the two support plates are in contact with each other, and the bottoms of the two support plates are away from each other.

[0009] Preferably, the bracket includes a support plate in a "U" shape structure and a connecting plate. The connecting plate is fixed between the tops of the support plates. The two sides of the support plate are located outside the two support frames. The connecting plate is located above the upper steel plate. Two handles are fixed on the upper surface of the connecting plate. Through holes are opened at both ends of the top of the support plate.

[0010] Preferably, four lifting ears are fixed to the lower surface of the cross beam, a lifting ring is fixed to the middle of the upper surface of the cross beam, and the lifting ears are connected to one end of the chain hook.

[0011] The advantages of the utility model are: the gravity of the protective frame is used to compress and fix the cathode carbon blocks on the two brackets, so that the two brackets slide relative to each other toward the middle of the support frame; when the support plate contacts the upper surface of the inclined support plate, the slide of the support plate will only cause it to slide upward relative to the protective frame, thereby exerting a further clamping force and further preventing the cathode carbon blocks from loosening and accidentally falling off.

[0021] A special fixture for cathode carbon blocks, comprising a protective frame 1, two brackets 2, a cross beam 3 and four chain hooks 4; wherein, the protective frame 1 includes: two support frames 1.1, and the tops of the two support frames 1.1 are fixedly connected by two square steels 1.2; on the support frame 1, there are: an upper steel plate 1.11, a lower steel plate 1.12 and two support plates 1.13. Two support plates 1.13 are symmetrically and fixedly arranged between the upper steel plate 1.11 and the lower steel plate 1.12. The tops of the two support plates 1.13 are in contact with each other, and the bottoms of the two support plates 1.13 are away from each other. Both ends of the protective frame 1 along its length direction are respectively sleeved with brackets 2; the bracket 2 includes a support plate 2.1 in a "U" shape structure and a connecting plate 2.2. A connecting plate 2.2 is fixed between the tops of the support plates 2.1; when in use, both sides of the support plate 2.1 are located outside the two support frames 1.1, the connecting plate 2.2 is located above the upper steel plate 1.11, two handles 2.21 are fixed on the upper surface of the connecting plate 2.2, through holes 2.11 are opened at both ends of the top of the support plate 2.1, and one side edge of the bottom of the bracket 2 is attached to the upper surface of the support plate 1.13; four lifting lugs 3.1 are fixed on the lower surface of the cross beam 3, a lifting ring 3.2 is fixed in the middle of the upper surface of the cross beam 3. One end of the lifting lug 3.1 is connected with the chain hook 4. The cross beam 3 is located above the two brackets 2, and the lower surface of the cross beam 3 is respectively connected with the four through holes 2.11 on the two brackets 2 through four chain hooks 4.

[0022] The working principle is as follows: Since there are gaps left for the cathode carbon blocks 5 placed in the workshop, before hoisting the cathode carbon blocks 5, first cover the protective frame 1 outside the cathode carbon blocks 5, and then respectively sleeve the two brackets 2 on both ends of the protective frame 1, so that the two support plates 2.1 are placed on the lower surfaces of both ends of the cathode carbon blocks 5. The position of the support plate 2.1 can be adjusted through the handle 2.21, and the cross beam 3 and the two brackets 2 are connected through the chain hook 4; finally, hook the hook on the crane to the lifting ring 3.2 and lift it upward; use the gravity of the protective frame 1 itself to press and fix the cathode carbon blocks 5 on the two brackets 2, so that the two brackets 2 slide relatively towards the middle of the support frame 1.1. When the support plate 2.1 contacts the upper surface of the inclined support plate 1.13, as the support plate 2.1 slides, it will only slide upward relative to the protective frame 1 itself, exerting a further clamping force to further prevent the cathode carbon blocks 5 from loosening and accidentally falling off.

[0023] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
