Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic aluminum production, and in particular relates to a movable split optical auxiliary positioning device for anode replacement operation in aluminum electrolytic production. Background Art

[0002] In the aluminum electrolysis production process, anode replacement is a very important link, which directly affects the electrolysis efficiency and product quality. The main steps of anode replacement include: taking out the remaining anode, loading the new anode and adjusting its position. The loading height of the new anode needs to be precisely controlled to ensure that the level of the bottom of the new anode in the electrolytic cell is at the same height as the bottom of the remaining anode. This process usually requires the use of special tools and methods to achieve precise positioning.

[0003] In the existing technology, a common solution is to use Figure 1 The conventional pocket ruler is used for positioning as shown in the figure. The specific operation steps are: before the broken anode is taken out, the contact point between the broken anode guide rod and the lower edge of the electrolytic cell beam busbar is used as the reference point to draw an identification line on the broken anode guide rod; after the broken anode is taken out, the pocket ruler is used to align with the identification line on the broken anode guide rod to mark it; then the marked pocket ruler is used to align with the marking point on the new anode guide rod to be installed and draw an identification line; finally, when the new anode is installed, the identification line on the new anode guide rod is aligned with the lower edge of the electrolytic cell beam busbar to achieve the purpose of accurately positioning the installation height of the new anode.

[0004] However, there are some problems with the existing solutions. First, since the residual anode is at a high temperature (850°C), there is a safety risk in the process of using a ruler to mark the marking line on the residual anode guide rod; secondly, manual visual marking is prone to large errors due to looking up, which will affect the height accuracy of the new anode installation, and further affect the electrolysis efficiency and product quality. Therefore, how to improve the accuracy of the new anode installation height while ensuring safety is an urgent problem to be solved in the current aluminum electrolysis production.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] As an example, Figure 2 As shown, in order to solve the above technical problems, this embodiment provides an optical positioning device and a residual anode bottom height positioning device arranged below the optical positioning device;

[0030] The optical positioning device includes an upper slide rail 1 and an upper slider 2; the upper slider 2 cooperates with the upper slide rail 1; a laser emitter 3 is fixedly arranged on the upper slider 2;

[0031] The residual anode bottom height positioning device comprises a movable base 4, a lower slide rail 5, a right-angle caliper 6 and a right-angle caliper height adjustment mechanism 7;

[0032] The bottom of the lower slide rail 5 is fixed on the movable base 4; the vertical section of the right-angle caliper 6 is arranged on the lower slide rail 5; the right-angle caliper height adjustment mechanism 7 is fixed on the lower slide rail 5;

[0033] The top of the vertical section of the right-angle caliper 6 is fixedly connected to the upper slide rail 1; a horizontal marking rod M is provided at the connection between the lower end of the upper slide rail 1 and the right-angle caliper 6; and the horizontal section of the right-angle caliper 6 is movably provided on the right-angle caliper height adjustment mechanism 7.

[0034] As attached Figure 3 The figure shows a side view of a movable split optical auxiliary positioning device for anode changing operation in aluminum electrolysis production.

[0035] The specific working principle of the utility model is as follows: the operator adjusts the height of the horizontal section of the right-angle caliper 6 through the right-angle caliper height adjustment mechanism 7. When the height of the right-angle caliper 6 rises, the vertical section of the right-angle caliper 6 rises synchronously, and the vertical section of the right-angle caliper 6 drives the upper slide rail 1 to rise until the horizontal section of the right-angle caliper 6 contacts the bottom of the residual anode. In this process, ensure that the contact pressure between the horizontal end of the right-angle caliper and the bottom of the residual anode is between 1-2N to avoid damage to the bottom of the residual anode.

[0036] The upper slide rail 1 drives the laser emitter 3 to move, align the laser emitter 3 with the marking line on the residual anode guide rod, and adjust the right-angle caliper height adjustment mechanism 7 so that the laser point projected on the residual anode guide rod coincides with the marking line according to the up and down sliding of the laser emitter 3 to locate the height of the marking line on the residual anode guide rod. Figure 4 The schematic diagram of positioning the height of the marking line on the residual anode guide rod L1 is shown. In this process, the operating voltage of the laser emitter 3 is ensured to be between 3-5V to ensure the stable operation of the laser emitter 3.

[0037] After aligning the marking line on the residual anode guide rod, just place the upper optical positioning device on the new anode and align the laser to draw the marking line on the new anode guide rod. Through the position of the horizontal marking rod M, the new anode installation height can be accurately located. In this process, ensure that the contact distance between the marking line on the new anode guide rod and the lower edge of the electrolytic cell beam busbar is between 0.1-0.5mm to ensure the accuracy of the new anode installation height.

[0038] The utility model can effectively solve the problems of safety risk and large positioning error in the process of locating the height of the marking line on the residual anode guide rod, and improve the accuracy of the height of the new anode installation under the premise of ensuring safety.

[0040] In actual application, the operator steps on the pedal to make the sleeve rod rotate with the rotating part. As the height of the sleeve rod 703 increases, the sleeve rod 703 drives the horizontal section of the right-angle caliper 6 to rise. At this time, the vertical section of the right-angle caliper 6 rises on the lower slide rail 5, and the vertical section of the right-angle caliper 6 drives the upper slide rail 1 to rise.

[0041] As an optional implementation, the rotating member 702 is a rotating drum; a rotating shaft is fixedly provided on the lower slide rail 5; and the rotating drum is sleeved on the rotating shaft.

[0042] In actual application, the rotating member adopts a rotating drum, and the pedal 701 and the sleeve rod 703 are fixed on the rotating drum to rotate synchronously around the rotating shaft, so that the operator can quickly adjust the height of the right-angle caliper 6 through the foot pedal 701.

[0043] As an optional implementation, a push-lock switch is provided on the upper slide block; a trigger assembly of the push-lock switch enters a fixing member provided on the upper slide rail.

[0044] In actual application, after the upper slider is raised to a stable state, the upper slider is fixed to the upper slide rail by pressing the locking switch, so that the position of the laser transmitter is fixed to ensure that the marking line on the new anode guide rod is accurately drawn.

[0045] As an optional embodiment, a spring is provided on the trigger assembly of the press-lock switch; a clamp assembly is fixedly provided at the end of the trigger assembly; the fixing piece of the upper slide rail is a blocking piece; the clamp assembly and the blocking piece cooperate to fix the upper slide block on the upper slide rail.

[0046] In actual application, after operating and pressing the button of the locking switch, the clamping head assembly is limited by the blocking member, thereby fixing the upper slider on the upper slide rail. After operating and pressing the button of the locking switch again, the clamping head assembly leaves the blocking member, and after the spring returns to its natural state, the upper slider detaches from the upper slide rail.

[0047] As an optional implementation, a fixed handle is provided on the upper sliding block.

[0048] In actual application, as shown in the attached Figure 2 As shown, the height of the upper slide block 2 on the upper slide rail 1 is adjusted by a fixed handle 9, thereby achieving adjustment of the position of the laser transmitter 3.

[0051] As an optional implementation, the mobile base includes a base plate, universal wheels and an oblique support frame; the universal wheels are arranged under the base plate; one end of the oblique support frame is fixed to the lower slide rail, and the other end is fixed to the base plate.

[0052] In actual application, the universal wheel is used to realize the rapid horizontal movement of the entire device, so that the horizontal section of the right-angle caliper can quickly reach the bottom of the residual anode guide rod. The oblique support frame can ensure that the lower slide rail is stably fixed on the floor.

[0053] As an optional implementation, as shown in the attached Figure 1 As shown, a plurality of limiting rings 12 are arranged on the side of the lower slide rail 5 ; the vertical section of the right-angle caliper 6 is inserted into the limiting ring 12 .

[0054] In actual application, when the right-angle caliper moves up and down on the lower slide rail 5 , the moving direction of the right-angle caliper 6 is restricted by the limit ring 12 , so as to prevent the right-angle caliper 6 from falling off the lower slide rail 5 .

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
