DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. EMBODIMENT

[0018] Please refer to Figures 1 to 4 The electrolytic aluminum anode new pole position positioning device is applied to the crown block moving mechanism 1, the electrolytic cell 2 is arranged below the crown block moving mechanism 1, the crown block moving mechanism 1 comprises the moving part 3 and the lifting part 4, the lifting part 4 is fixedly connected and arranged at the bottom end of the moving part 3, one end of the lifting part 4 is provided with the holding assembly for holding the anode 5, the holding assembly comprises the connecting plate 17, one end of the connecting plate 17 is fixedly connected with one end of the lifting part 4, the other end of the connecting plate 17 is fixedly connected with two vertical plates 18, one end of the two vertical plates 18 is fixedly connected with the clamping plate 19, the clamping plate 19 is used for clamping the anode 5, and the utility model further comprises the fixed frame 6, the lengthening plate 7, the scribing head 8 and the two laser emitters 9.

[0019] It should be noted that the internal chip of the laser emitter 9 adopts a special material (which can withstand high temperature), and the laser emitter 9 adopts a vacuum packaging process, adopts micro-channel liquid cooling packaging, and the chip is welded on the diamond heat sink, so that the thermal resistance is reduced, and the laser emitter 9 can adapt to high temperature;

[0020] For example Figure 4As shown, the fixed frame 6 is detachably fixedly connected to the middle part of the gripping assembly by a plurality of bolts 20. One end of the fixed frame 6 is provided with a groove 14, the inner side wall of the groove 14 is in sliding fit with the middle part of the gripping assembly, a heat insulation layer 16 is arranged in the groove 14, the heat insulation layer 16 is an inorganic non-metallic heat insulation material, the inner side wall of the heat insulation layer 16 is in sliding fit with the side walls of the two vertical rods, the plurality of bolts 20 penetrate through the groove 14 and the heat insulation layer 16, and the fixed frame 6, the heat insulation layer 16 and the two vertical rods are fixedly connected by the plurality of bolts 20. The fixed frame 6 is horizontally fixed on the two vertical rods and is above the clamping plate 19.

[0021] As shown in Figure 2 and Figure 3 As shown, the lengthened plate 7 is arranged on one side of the fixed frame 6 in a lifting manner through a lifting mechanism. The lifting mechanism comprises a reciprocating lead screw 10, a lead screw nut 12 and a motor 13. A moving groove 11 is formed in the fixed frame 6. Two ends of the reciprocating lead screw 10 are rotationally connected to the inner top wall and the inner bottom wall of the moving groove 11 respectively. The reciprocating lead screw 10 is sleeved with the lead screw nut 12 matched therewith. The reciprocating lead screw 10 and the lead screw nut are matched through the ingenious design of screw thread rotation, so as to convert the rotary motion into automatic reciprocating linear motion. The lead screw nut 12 is in sliding fit with the inner wall of the moving groove 11. One end of the lead screw nut 12 is fixedly connected to the other end of the lengthened plate 7. The motor 13 is installed at the top end of the fixed frame 6. The output end of the motor 13 is fixedly connected with one end of the reciprocating lead screw 10 in a same axis. The motor 13 is made of high-temperature-resistant insulating material and internally adopts a water cooling system to circulate and take away heat through pipelines. The cable connected with the motor 13 is also made of high-temperature-resistant material. Two telescopic lead screw sheaths 15 are arranged on the moving groove 11. One end of each of the two telescopic lead screw sheaths 15 is fixedly connected to the inner top wall and the inner bottom wall of the moving groove 11 respectively. The other end of each of the two telescopic lead screw sheaths 15 is fixedly connected to two ends of the lead screw nut 12 respectively. By starting the motor 13, the output end of the motor 13 rotates to drive the reciprocating lead screw 10 to rotate. The reciprocating lead screw 10 rotates to drive the lead screw nut 12 to move up and down along the inner wall of the moving groove 11. The lead screw nut 12 drives the lengthened plate 7 to move reciprocatingly and longitudinally. In the reciprocating movement of the lead screw nut 12, the two telescopic lead screw sheaths are continuously stretched and contracted. In this way, dust can be prevented from entering the moving groove 11 and being adsorbed on the reciprocating lead screw 10 when the anode 5 is replaced and the mark line is drawn, so as to avoid damage to the reciprocating lead screw 10. By arranging the heat insulation layer 16, the high temperature of the old anode 5 when the old anode 5 is clamped and replaced can be prevented from causing the temperature of the motor 13 to be too high, so as to affect normal work.

[0022] It should be noted that when the anode 5 is replaced, the temperature in the electrolytic cell 2 is too high. The mark line can be drawn after the temperature is reduced, so as to avoid that the high temperature causes the device to be difficult to be normally used;

[0023] As shown in Figure 3As shown, one end of the scribing head 8 is fixedly connected with one end of the lengthened plate 7, two laser emitters 9 are respectively installed on two outer side walls of the lengthened plate 7, the lengthened plate 7 and the scribing head 8 have the same length, the two laser emitters 9 are symmetrically arranged at two ends of the lengthened plate 7, the lengthened plate 7 is driven to reciprocatingly move longitudinally by the motor 13, the lengthened plate 7 drives the scribing head 8 to move, the lengthened plate 7 simultaneously drives the two laser emitters 9 to reciprocatingly move longitudinally, the laser rays emitted by the two laser emitters 9 are two "points", the scribing head 8 is provided with a piercing part, the connecting line of the two "points" coincides with the center of the scribing head 8, and the distance of the connecting line of the two "points" generated by the two laser rays is the same as the length of the scribing head 8;

[0024] It also needs to be supplemented that when the aluminum electrolysis cell ends work, the ground at the original installation position of the residual anode (i.e. the "cell bottom pad layer" at the bottom of the electrolysis cell) usually accumulates a certain amount of particulate impurities, the accumulated particulate impurities are essentially solid materials that do not participate in the reaction or are deposited after the reaction in the electrolysis process, and because the accumulated impurities are subjected to high temperature in the electrolysis cell and extrusion of the materials for a long time, the accumulated impurities can be relatively compact, the lengthened plate 7 is driven by the motor 13 to move longitudinally downward toward the accumulated impurities, and the scribing head 8 is inserted into the impurity layer, and part of the lengthened plate 7 can also be inserted into the impurity layer (the thickness of the impurity layer needs to be considered), an "opening" usually appears on the impurity layer, which is a marking line, when the residual anode is taken out, although a certain disturbance can be generated to the impurity layer, because the impurity layer already has a certain shape and structure, the particles around the opening are difficult to automatically restore to the original position to completely fill the opening, after the residual anode is taken out, the impurity layer still maintains a relatively stable state, and the opening continues to exist, so the "opening" generally does not disappear.

[0025] It also needs to be further explained that the motor 13 and the laser emitter 9 in the embodiment are conventional devices known to those skilled in the art and purchased on the market, and can be selected or customized according to actual needs, and in the patent, we only use them and do not improve their structure and function, and as long as the requirements in the instruction manual are met, the setting mode, the installation mode and the electrical connection mode can be debugged and operated by those skilled in the art, and here, they will not be described in detail, and the motor 13 and the laser emitter 9 are provided with control switches matched therewith, the installation positions of the control switches are selected according to actual use requirements, and the control switches can be operated and controlled by the operating personnel.

[0026] Working principle: the electrolytic aluminum anode new pole position positioning device is applied to the overhead traveling crane moving mechanism 1, when the anode 5 in the electrolytic cell 2 needs to be replaced, after the temperature in the electrolytic cell 2 is reduced, the moving part 3 in the overhead traveling crane moving mechanism 1 moves horizontally and drives the lifting part 4, the gripping assembly and the electrolytic aluminum anode new pole position positioning device to move to the top of the electrolytic cell 2, then the electrolytic cell 2 is opened, the old anode 5 to be replaced is "exposed" in the electrolytic cell 2, the gripping assembly is accurately moved to the top of the old anode 5 by the overhead traveling crane moving mechanism 1, so that the two clamping plates 19 are in contact with the top end of the old anode 5, and the old anode 5 is fixed on the two clamping plates 19 through relevant fixing technology (such as adsorption fixing), at this time, the extension plate 7 is on one side of the old anode 5, and the screw nut 12 is at the top end in the moving groove 11, the motor 13 is started, the output end of the motor 13 rotates to drive the reciprocating screw rod 10 to rotate, the reciprocating screw rod 10 drives the screw nut 12 to move downward along the inner wall of the moving groove 11, the screw nut 12 drives the extension plate 7 to move downward, in the movement process of the screw nut 12, the two telescopic screw rod sheaths are continuously stretched and contracted, so that the dust generated in the process of replacing the anode 5 and drawing the mark line can be prevented from entering the moving groove 11 and being adsorbed on the reciprocating screw rod 10, thereby avoiding damage to the reciprocating screw rod 10, the heat insulation layer 16 is arranged to prevent the high temperature of the old anode 5 from causing the temperature of the motor 13 to be too high when the old anode 5 is clamped and replaced, thereby affecting normal work, since the ground in the electrolytic cell 2 is covered with thick dust, the extension plate 7 drives the marking head 8 to penetrate into the dust layer and generate a mark line, the old anode 5 is driven to move out of the electrolytic cell 2 and the new anode 5 is fixed at the bottom of the gripping assembly, the new anode 5 is above the electrolytic cell 2 through the overhead traveling crane moving mechanism 1, the two laser emitters 9 are started, the laser rays emitted by the two laser emitters 9 are two "points", the line connecting the two "points" is in the same straight line as the mark line, and the mark line drawn by the marking head 8 is between the two "points", so the positioning of the new anode 5 is completed, the new anode 5 is driven to move longitudinally by the lifting part 4 and placed in the electrolytic cell 2, so the replacement of the anode 5 is completed, and the dust accumulated in the electrolytic cell 2 can be removed subsequently.

[0027] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
