DETAILED DESCRIPTION
[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.
[0025] like Figures 1 to 3 As shown, the utility model discloses a working arm of a submerged arc furnace tapping device, comprising a working arm body 1, a front hinge point support 2 and a rear hinge point support 3.
[0026] The lower surface of the working arm body 1 is provided with a plurality of mounting hole groups, each mounting hole group includes a front screw hole 11 and a rear screw hole 12. The front hinge point support 2 is detachably fixedly connected to the front screw hole 11 by a threaded fastener. The rear hinge point support 3 is detachably fixedly connected to the rear screw hole 12 by a threaded fastener. These mounting hole groups are arranged along the length direction of the working arm body 1 on the lower surface of the working arm body 1.
[0027] The working arm body 1 is connected to the furnace front equipment through the front hinge point support 2 and the rear hinge point support 3. Since the mounting hole groups are arranged in multiple groups on the lower surface of the working arm body 1, the positions of these mounting hole groups are different in the front and back. By installing the front hinge point support 2 and the rear hinge point support 3 on different mounting hole groups, the positions of the front hinge point support 2 and the rear hinge point support 3 on the working arm body 1 can be changed, thereby adjusting the distance between the working arm and the ore-heating furnace. When the working arm body 1 needs to be away from the ore-heating furnace, the front hinge point support 2 and the rear hinge point support 3 can be installed on the front mounting hole group. Since the position of the furnace front equipment remains unchanged, this will cause the working arm to be located backward after installation, increasing the distance between the working arm and the ore-heating furnace. Conversely, when the working arm body 1 needs to be close to the ore-heating furnace, the front hinge point support 2 and the rear hinge point support 3 can be installed on the rear mounting hole group. Since the rear hinge point support 3 is actually used to connect the piston rod of the hydraulic cylinder, the extension and contraction of the hydraulic cylinder can control the pitch of the working arm. Therefore, the front hinge point support 2 and the rear hinge point support 3 can also be installed on different hole groups, so that the relative distance between the two will also change, and the pitch angle of the working arm can also be adjusted. The farther the distance between the front hinge point support 2 and the rear hinge point support 3 is, the smaller the pitch of the working arm is, and vice versa.
[0028] Depend on Figure 3 It can be seen that the working arm can also include a front locating pin 4. Each group of mounting holes also includes a first locating hole 13. The two ends of the front locating pin 4 are respectively connected to the first locating hole 13 and the front hinge point support 2. In this embodiment, a front center hole 21 is provided in the middle of the front hinge point support 2 for the front locating pin 4 to be inserted. The front locating pin 4 is a two-section structure with different diameters, and its large diameter part is inserted in the front center hole 21, and the small diameter part is inserted in the first locating hole 13. The front locating pin 4 can play a role in positioning and limiting, ensuring accurate positioning, no shaking, and firm installation. In other embodiments of the utility model, the front locating pin 4 can also be fixed to the front hinge point support 2 by other common connection methods such as welding.
[0029] The working arm may also include a rear locating pin 5. Each group of mounting holes also includes a second locating hole (not shown in the figure). The two ends of the rear locating pin 5 are respectively connected to the second locating hole and the rear hinge point support 3. In the present embodiment, a rear center hole 31 is provided in the middle of the rear hinge point support 3 for the insertion of the rear locating pin 5. The rear locating pin 5 is a two-stage structure with different diameters, wherein the large diameter portion is inserted in the rear center hole, and the small diameter portion is inserted in the second locating hole. The rear locating pin 5 can play a role in positioning and limiting, ensuring accurate positioning, no shaking, and firm installation. In other embodiments of the utility model, the rear locating pin 5 can also be fixed to the rear hinge point support 3 by other common connection methods such as welding.
[0030] In this embodiment, the number of front screw holes in each group of the mounting holes is set to eight, and the front hinge point support includes two legs and a hollow tube, and the legs are welded to the hollow tube. Figure 3 It can be seen that four front mounting holes 22 are provided on each leg, and these front mounting holes 22 are all open holes for bolts to pass through. The eight front screw holes 11 are divided into four groups, and the front screw holes 11 of each group correspond to the four front mounting holes 22 on the same leg, that is, after each bolt passes through a front mounting hole 22, it can be screwed into one of the front screw holes 11; the first positioning hole 13 is located at the center of the layout of the four front screw holes 11 in the same group.
[0031] The number of rear screw holes 12 is set to 4, and the rear hinge point support includes a support foot and a hollow tube, and the support foot is provided with four rear mounting holes 32. The four rear screw holes 12 correspond to the positions of the four rear mounting holes 32. Similar to the first positioning hole, the second positioning hole is located at the center position of the layout of the four rear screw holes 12.
[0032] The utility model also discloses a submerged arc furnace unloading equipment, which is arranged on an arc track beside the submerged arc furnace and comprises an industrial silicon unloading machine and a working arm of the submerged arc furnace unloading equipment. The industrial silicon unloading machine drives the working arm of the submerged arc furnace unloading equipment to work and complete the unloading operation.
[0033] The exemplary embodiments of the present invention are specifically shown and described above. It should be understood that the present invention is not limited to the disclosed embodiments, but rather, the present invention is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
