Description

Technical field:

[0001] The utility model relates to the technical field of anode carbon block equipment, in particular to an auxiliary device for preventing an anode carbon block clamp from falling off. Background technology:

[0002] Prebaked anode carbon blocks are the main consumables that are indispensable in modern electrolytic aluminum production. The consumption of anode carbon blocks accounts for a large proportion of the production cost of electrolytic aluminum. Therefore, reducing the consumption of anode carbon blocks per ton of aluminum is of great significance to reducing the production cost of electrolytic aluminum.

[0003] Common anode carbon blocks: There are multiple round cones evenly distributed along the length direction on the middle of the table surface of the rectangular base, which are integrated with the rectangular base. A carbon bowl is constructed on each round cone. By casting a phosphorus iron ring in the carbon bowl of the anode carbon block, the anode steel claw and the anode carbon block are interlaced and connected for conductive load-bearing.

[0004] At present, when transporting anode carbon blocks, a steel wire rope is mainly set on the side surfaces of three anode carbon blocks, and the steel wire rope is hooked by the chain hook on the overhead crane. In the process of lifting the steel wire rope, the rope bodies on both sides of the steel wire rope will move toward the middle to increase the friction between the steel wire rope and the surface of the anode carbon block, thereby clamping the anode carbon block; however, with the long-term use of the steel wire rope, the surface of the rope will become smooth, and there is a risk of the anode carbon block accidentally falling off from the steel wire rope.

[0005] Therefore, new technical solutions need to be proposed to reduce the occurrence of accidents. Utility model content:

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-10 The utility model provides a technical solution for an auxiliary device to prevent the anode carbon block fixture from falling off:

[0027] An auxiliary device for preventing an anode carbon block fixture from falling off comprises a corner protector 1, a pressure plate 2 and a clamping plate 3; the existing anode carbon block 5 is provided with chamfers 5.1 on all sides of the bottom, the corner protector 1 is provided with a rope threading groove 1.1 obliquely downwardly in the middle of the upper surface along the length direction, the rope threading groove 1.1 is used to place a steel wire rope 6, the corner protector 1 is provided with a clamping groove 1.2 on the inner top surface of the rope threading groove 1.1 on the side of the anode carbon block 5, the bottom of the corner protector 1 is provided with a triangular pad 1.3 on the side of the anode carbon block 5, the shape of the triangular pad 1.3 is consistent with the shape of the chamfer 5.1, the vertical surface of the corner protector 1 on the same side and the upper surface of the triangular pad 1.3 correspond to the vertical surface of the bottom of the anode carbon block 5 and the inclined surface generated by the chamfer, respectively.

[0028] A pressure plate 2 is rotatably arranged on one side of the middle part of the corner guard 1 away from the anode carbon block 5, the lower surface of one end of the pressure plate 2 is overlapped with the upper surface of the bottom of the slot 1.2, and a limiting slide groove 2.1 is provided on the upper surface of the pressure plate 2. A clamping plate 3 is elastically slidably arranged in the limiting slide groove 2.1, and one end of the clamping plate 3 is movably clamped in the slot 1.2.

[0029] The lower surface of the middle part of the pressure plate 2 is arc-shaped, and two guide pillars 2.2 are fixedly arranged in the limiting slide groove 2.1 on its upper surface. Each guide pillar 2.2 is sleeved with a compression spring 4, and one end of the compression spring 4 abuts against the end surface of the limiting slide groove 2.1.

[0030] The card plate 3 is slidably arranged in the limiting slide groove 2.1. Two guide holes 3.1 are provided on one end surface of the card plate 3 along the sliding direction. The guide column 2.2 is movably inserted into the corresponding guide hole 3.1. The other end of the compression spring 4 abuts against the inner end surface of the corresponding guide hole 3.1. A wrench 3.2 is fixed on the upper surface of the card plate 3.

[0031] The working principle is: when preparing to put the steel wire rope 6 on the side surface of the three anode carbon blocks 5, first prepare two of the devices, and let the corner protector 1 fit on the bottom surface of the three anode carbon blocks 5. After the fit is firm, the steel wire rope 6 is placed in the rope threading groove 1.1 at the same time.

[0032] like Figure 6 As shown, the pressure plate 2 is then rotated so that the clamping plate 3 on the pressure plate 2 is clamped in the clamping groove 1.2 under the action of the compression spring 4, so that the steel wire rope 6 is locked by the pressure plate 2 to prevent the steel wire rope 6 from escaping. It should be noted that even if the pressure plate 2 is not used to lock the steel wire rope 6, since the rope threading groove 1.1 is inclined relative to the anode carbon block 5, as the two side parts of the steel wire rope 6 move toward the middle and exert force, the steel wire rope 6 will not fall during the rising process. The purpose of adding this part of the structure is to avoid any accidents.

[0033] As the steel wire rope 6 is hooked up and moves under the action of the chain hook, the two side parts of the steel wire rope 6 will move toward the middle and exert force, thereby increasing the friction between the steel wire rope 6 and the surface of the anode carbon block 5, thereby clamping the anode carbon block 5. At the same time, under the action of the steel wire rope 6, the corner protector 1 of the device firmly grasps the bottom edge surface of the anode carbon block 5, and hooks the bottom chamfer 5.1 of the anode carbon block 5 through the triangular pad 1.3, effectively avoiding the anode carbon block 5 from accidentally falling off the steel wire rope, thereby reducing the occurrence of accidents.

[0034] Meanwhile, when disassembling, the steel wire rope can be taken out by sliding the wrench 3.2 on the clamping plate 3, which has a simple structure and is convenient and quick.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
