[0002] The operation of changing the pole of the electrolytic cell is the most important link in the electrolytic production process. The operation process is dangerous and labor-intensive. The pole changing operation requires high precision and strong responsibility. The quality of the pole changing operation directly affects the index data of current efficiency and anode consumption. The pole changing operation has relatively high requirements for the measurement accuracy of the new and old anodes. The height data of the discharge pole, whether high or low, will have a large fluctuation and impact on the electrolytic production. The traditional measurement method uses a ruler to draw lines to compare the bottom of the new and old anodes.

Example

[0028] See also Figure 1-7The present embodiment provides the following technical solutions: an electrolytic aluminum pole-changing measuring device, comprising a vehicle body 1, a vehicle frame 2 fixedly arranged above the vehicle body 1, and a shell 3 fixedly arranged outside the vehicle frame 2, a top frame 4 fixedly arranged above the vehicle frame 2, and a top shell 5 fixedly arranged above the top frame 4. In some embodiments, the vehicle frame 2 is a rectangular structure, and the top frame 4 is a triangular structure. The shell 3 and the top shell 5 can provide a protective effect on the device.

[0029] The vehicle body 1 includes a base frame 101 and running wheels 102 rotatably arranged at the bottom of the base frame 101 . A handrail 103 is fixedly arranged at one end of the base frame 101 . The running wheels 102 and the handrail 103 facilitate workers to move the device.

[0030] The cross cursor locator 6 is fixedly arranged on the top frame 4, and a first measuring window 7 for the cross cursor locator 6 to measure is arranged on the top shell 5. The cross cursor locator 6 mainly plays an auxiliary positioning effect on the anode, so as to assist manual finding of the center position of the anode.

[0031] There are three cross cursor locators 6, one of which is set in the middle above the top frame 4, and the other two cross cursor locators 6 are respectively set at an angle on the side walls of the top frame 4. In some embodiments, the height of the cross cursor locator 6 on the top of the top frame 4 is higher than the height of the cross cursor locator 6 on the side of the top frame 4. By setting the positions of the three cross cursor locators 6, the effect of positioning the anode is increased.

[0032] Laser scanner 10, a mounting frame 8 is provided on the frame 2 below the top frame 4, telescopic frames 9 are symmetrically provided on the left and right sides of the mounting frame 8, laser scanners 10 are fixedly provided on the ends of the telescopic frames 9 on the left and right sides that are away from each other, a second measuring window 11 for the laser scanner 10 to extend is provided on the outer shell 3, the other ends of the telescopic frames 9 on the left and right sides are connected by a synchronous telescopic mechanism 12, which is used to make the telescopic frames 9 on both sides extend or extend into the inner part of the outer shell 3 at the same time, through the cross cursor locator 6 and the laser scanner 10, a method of direct scanning of the bottom of the anode is adopted to directly measure the bottom of the new pole and the residual pole, and the measurement data is not affected by mechanical vibration and other factors, and the bottom scanning method is adopted, so the measurement accuracy is higher and the stability is stronger.

[0033] In some embodiments, the data collected by the cross cursor locator 6 and the laser scanner 10 are collected through the anode height measurement system, and the height difference between the residual pole and the new pole is calculated by the system, and the initial value of the residual pole out of the slot is called up, and the position of the new pole is determined after calculation.

[0034] The synchronous telescopic mechanism 12 includes a lead screw 1201 arranged below the telescopic frame 9, the lead screw 1201 is rotatably connected to the mounting frame 8, and the telescopic frame 9 is threadedly sleeved on the lead screw 1201; a driving motor 1202, the driving motor 1202 is fixedly arranged on the mounting frame 8, and a first bevel gear 1203 is fixedly arranged on the output end of the driving motor 1202, and a second bevel gear 1204 is fixedly arranged on the opposite end of the lead screws 1201 on the left and right sides, and the second bevel gear 1204 is meshingly connected with the first bevel gear 1203. Through the driving motor 1202, the lead screws 1201 on the left and right sides can be rotated in the opposite direction, so that in the process of the lead screw 1201 rotating, the telescopic frames 9 on the left and right sides can be simultaneously approached or moved away, and when measuring the anode, the laser scanners 10 on the left and right sides are simultaneously extended out of the frame 2. After the measurement is completed, the laser scanners 10 on the left and right sides are simultaneously extended into the inner side of the frame 2, which plays a protective role for the laser scanner 10.

A pulley 1207 is rotatably connected to the movable seat 1206, and the pulley 1207 is located inside the guide rails 1205 and is slidably connected to the guide rails 1205. Through the guide rails 1205, the movable seat 1206 and the pulley 1207, the telescopic frame 9 is limited, thereby increasing the stability of the telescopic frame 9 when moving.

[0036] A mounting base 13 is fixedly provided on the telescopic frame 9 above the laser scanner 10, and an optical glass 14 is fixedly provided on the mounting base 13 for protecting the lens of the laser scanner 10.

Through the sealing frame 15, the second measuring window 11 can be sealed after the laser scanner 10 is extended into the frame 2, thereby further protecting the laser scanner 10 and preventing the second measuring window 11 from being in an open state when the device is not measuring the anode.

[0038] The frame 2 is also provided with a power supply 16 , which is electrically connected to the cross cursor locator 6 , the laser scanner 10 and the drive motor 1202 , and the power supply 16 provides power support for the device.

[0039] The working principle of the utility model is as follows: the first step: using the lifting equipment, the residual anode is lifted out of the tank, and the initial value height data of the residual anode is obtained through the anode height measurement system;

[0040] Step 2: Start the cross cursor locator 6 and the laser scanner 10 to measure the absolute height data of the residual anode, and enable the anode height measurement system to collect the data;

[0041] Step 3: Start the cross cursor locator 6 and the laser scanner 10 to measure the absolute height data of the new pole, and enable the anode height measurement system to collect the data;

[0042] Step 4: The anode height measurement system calculates the height difference between the residual pole and the new pole, and retrieves the initial value of the residual pole out of the slot. After calculation, the position of the new pole is determined, and then the lifting equipment is controlled to place the new pole into the slot.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
