Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic aluminum production, and relates to a tool for punching holes in the crust of an electrolytic cell. Background Art

[0002] The crust of the electrolytic cell refers to the crust phenomenon formed inside the electrolytic cell during the aluminum electrolysis process. The crust on the surface of the molten aluminum is a complete Al2O3 crust retained on the electrolytic cell, which can cover the periphery and sides of the anode, reducing the oxidation and burning loss of the anode. At the same time, as a poor conductor of heat, the surface crust plays an adiabatic and heat-preserving role, reducing the heat loss of the cell. During the aluminum suction operation, the cover plate at the end face of the electrolytic cell is opened, and the aluminum suction pipe of the vacuum ladle is inserted into the electrolytic cell to suck the liquid aluminum. However, before sucking the aluminum, a hole needs to be punched in the crust so that the aluminum suction pipe can be inserted into the liquid aluminum. The traditional operation method is that workers grasp a steel drill to punch a hole, which has a high risk factor, poor working environment, high labor intensity, and low efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings of the present utility model. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0017] Embodiment 1: Please refer to Figures 1-3 ;

[0018] This embodiment provides a tool for punching holes in the crust of an electrolytic cell, which is applied before the aluminum suction operation; it punches through the crust covering the upper surface of the molten aluminum 81 from the hatch at the end of the electrolytic cell 8; it includes a pneumatic pick 1; the pneumatic pick 1 is fixedly connected to a swing plate 2, the upper end of the swing plate 2 is hinged to one end of a support rod 3, and its lower end is hinged to one end of a connecting rod 4. The other end of the connecting rod 4 is hinged to the lower end of a sliding sleeve 5. The sliding sleeve 5 is sleeved on the support rod 3 for the sliding sleeve 5 to slide along the support rod 3; a row of equally spaced pin holes 31 are provided on the support rod 3, and a jack 51 is provided on the sliding sleeve 5 for the sliding sleeve 5 to be fixed to the support rod 3 by pin connection; a straight rod 32 is fixedly provided on the support rod 3, and the upper end of the straight rod 32 is ball-jointed to a portal bracket 6; the lower end of the portal bracket 6 is fixedly connected to a movable vehicle body 67.

[0019] During use, first, by sliding the sliding sleeve 5, the angle between the pneumatic pick 1 and the support rod 3 is pre-adjusted, a pin is inserted to fix the sliding sleeve 5, and then the pneumatic pick 1 and the support rod 3 are fixed together; then, the pneumatic pick 1 is started and the vehicle body 67 is moved so that the pneumatic pick 1 extends into the electrolytic cell 8 from the hatch at the end of the electrolytic cell 8, and the drill rod of the pneumatic pick 1 is in a continuously telescoping state; then, the other end of the support rod 3 is grasped and lifted so that the drill rod moves downward until it hits the crust 82 to start shell punching; then, taking advantage of the ball joint connection between the support rod 3 and the portal bracket 6, the other end of the support rod 3 is grasped and continuously swung until a hole is punched in the crust 82 for the suction pipe of the vacuum ladle to be inserted into the molten aluminum 81. After the hole punching is completed, the end of the support rod 3 is pressed down to lift the pneumatic pick 1, and then the vehicle body 67 is moved so that the pneumatic pick 1 withdraws from the hatch. Finally, the vacuum ladle enters the site for aluminum suction operation.

[0020] Among them, the pneumatic pick 1 is an existing product on the market, and the B47 type pneumatic pick is selected in this embodiment; as Figure 2 shown, two handlebars of the pneumatic pick 1 are fixed by two snap rings, and then with a pressing plate, the body of the pneumatic pick 1 is pressed against the side of the swing plate 2, so as to fix the pneumatic pick 1 and the swing plate 2. Moreover, a top support bolt 21 is preset on the swing plate 2, and the end of the top support bolt 21 presses against the preset switch plate on the pneumatic pick 1, making the pneumatic pick 1 in a normally open state; the start and stop of the pneumatic pick 1 are controlled by a valve preset on the high-pressure air pipe connected to the pneumatic pick 1, so that the switch of the pneumatic pick 1 can be controlled away from high temperature. And the power of the pneumatic pick 1 is much greater than that of a manual steel drill rod, greatly improving the hole punching efficiency and significantly reducing the labor intensity. In addition, the support rod 3 is also used as a lever, making it labor-saving to control the pneumatic pick 1. Therefore, preferably, the ball joint on the support rod 3 is arranged close to the pneumatic pick 1.

[0021] Exemplary ball hinge method, the upper end of the straight rod 32 is fixedly provided with a ball head 33; the ball head 33 is seated in a ball bowl 61 preset in the middle of the portal frame 6, and the straight rod 32 extends out from a tapered hole 62 preset at the lower end of the ball bowl 61, for the upper end of the straight rod 32 to be ball-hinged to the portal frame 6. It can be seen that the support rod 3 is hung at the upper end of the portal frame 6 and is ball-hinged, so that the support rod 3 can swing at any angle, facilitating the hole punching operation. In addition, under normal conditions, affected by gravity, the ball head 33 is always seated in the ball bowl 61 and will not fall off.

[0022] In order to avoid dust pollution of the ball hinge, the upper end of the portal frame 6 is fixedly connected with a ball cover 63; the ball cover 63 covers the ball head 33. On the other hand, it also forcibly blocks the ball head 33 from disengaging from the ball bowl 61, with better reliability.

[0023] The ball cover 63 is detachably connected to the portal frame 6 for easy maintenance and replacement. A set of connection holes 64 are respectively provided at both ends of the ball cover 63; the connection holes 64 correspond to the positions of bolt holes 65 preset at the upper end of the portal frame 6, for the ball cover 63 to be detachably connected to the upper end of the portal frame 6 through bolts.

[0024] In order to facilitate the grasping operation, an armrest ring 34 is fixedly provided at the other end of the support rod 3 away from the pneumatic pick 1.

[0025] A further optimization is that it also includes a reflector 7; the reflector 7 is fixedly connected to a lens support plate 71, one side of the lens support plate 71 is fixedly connected with a mounting plate 72, and a mounting hole is provided at the end of the mounting plate 72; a threaded hole 66 is preset on the upper side of the portal frame 6; a wing bolt 73 passes through the mounting hole and is screwed into the threaded hole 66, for fixing the mounting plate 72 to the top of the portal frame 6 through bolt connection. It can be seen that, as Figure 1 shown, through the reflector 7, the operator standing at the rear end of the support rod 3 can observe the working condition of the pneumatic pick 1 through the reflector 7, with more accurate operation and higher efficiency. And, by loosening the wing bolt 73, the angle of the reflector 7 can be adjusted, which is convenient to use.

[0026] In short, this device can enable the staff to operate away from the high-temperature area, improving safety and the working environment; the working angle of the pneumatic pick 1 can be adjusted, and it can swing at any angle during the hole punching operation, with good flexibility, labor-saving operation, and high hole punching efficiency.

[0027] The parts not detailed in the present utility model are prior arts; for those of ordinary skill in the art, the technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. The scope of the present utility model is defined by the appended claims and their equivalents.
