Problems solved by technology
The deeper the drill, the higher the temperature, the less heat can be dissipated, the cutting efficiency will be significantly reduced, and the hole opening will be more difficult
[0005] The existing method only uses a drilling tool to open the hole. In the later stage of the drilling work, the drilling tool wears seriously and the efficiency is very low. At the same time, the service life of the drilling tool is reduced and the loss of the drilling tool is increased.
If a drilling tool is damaged without completing a hole opening, replacing the drilling tool increases the time of the drilling operation

Embodiment Construction
[0022] In order to enable the examiner to further understand the structure, features and other purposes of the present invention, the attached preferred embodiments are attached with accompanying drawings in detail as follows. The embodiments illustrated in the accompanying drawings are only used to illustrate the technical solution of the present invention , not to limit the present invention.
[0023] See figure 1 , figure 1 It is a three-dimensional structure schematic diagram of the alternate eye opening mechanism of the present invention. Such as figure 1 As shown, the eye opening mechanism of the present invention includes two rotary devices 1, two supporting devices 2, a working drilling tool 3, a spare drilling tool 4 and a jib 5. Each rotary device 1 is provided with at least two through holes and reciprocates around a fixed central axis. The two rotary devices 1 are respectively provided with an appropriate distance and embedded in the supporting device 2; the two...

The invention provides an alternate windowing mechanism used for windowing a submerged arc furnace. The alternate windowing mechanism comprises two rotation devices, two supporting devices, a work drilling tool, a standby drilling tool and a cantilever crane, wherein each rotation device is provided with at least two through holes and does reciprocating rotation around a fixed center shaft; the rotation devices are separately arranged for a proper distance and are respectively embedded in the two supporting devices; the two supporting devices respectively support the corresponding rotation device and are fixedly arranged on the cantilever crane; the work drilling tool and the standby drilling tool respectively penetrate through the corresponding through hole in each rotation device to be fixed to the rotation devices. According to the alternate windowing mechanism, when one drilling tool is used for windowing to a certain degree, the drilling tool is retreated and cooled, the other drilling tool is switched for continuing windowing, thus continuous multiple windowing can be realized until the windowing process is finished, and meanwhile, the time for replacing the drilling tools in the windowing process is also shortened, so the windowing efficiency is favorably improved.
Description
technical field [0001] The invention relates to a mechanism for opening holes of submerged arc furnaces, in particular to a mechanism capable of opening holes in turn. Realize that multiple drilling tools work in turn to prolong the life of the drilling tools. Background technique [0002] In the production of submerged arc furnace, every once in a while, it is necessary to open the furnace eye to discharge the metallurgical products in the furnace. After the product is finished, the furnace eye is blocked. Wait until the next cycle, and then open the furnace eye, so repeatedly, continuously. [0003] The eye opener is widely used in submerged arc furnaces for the production of ferroalloys. It is divided into trolley type, floor type, and suspension type. The power forms include electric, hydraulic, and pneumatic. The eye-opening machine improves the level of mechanization and shortens the time for eye-opening. The eye opening machine is mainly composed of a boom, a trav...
