Background Technology

[0003] Generally, when producing molten steel in a steel mill, there is an electric furnace device that uses electricity to melt scrap metal inside the furnace. In this device, scrap metal is introduced into the furnace, and a cable connected to it is provided at the bottom of the furnace. When an electrode rod moves and approaches the scrap metal, an arc is generated by the electrical action of the electrode rod driven by the power supply of the cable, and the heat generated by this arc enables the scrap metal to melt into a liquid metal inside the furnace.

[0004] At this time, in addition to the power supply cable for supplying power to the electrode rods, cables supplying oxygen and water for cooling each electrode rod and melting scrap metal are essential, and the cables move together with the movement of the joints, that is, the movement of the cable frame that supports the cables.

[0005] However, in the conventional process of moving the electrode rod, a problem arises where the cable gets damaged by twisting or dragging on the ground due to the movement of the cable frame (joint). Prior art literature

[0032] The above cable connection pipe (154) is provided in the above cable connection frame (150).

[0033] In the present invention, a plurality of cable connection pipes (154) are configured to be mounted on a cable connection frame (150).

For reference, the front end of a cable connection pipe (154) is configured to be connected to a supply line inside the cable connection frame (150) by a connection pipe.

[0034] In the present invention, a plurality of cable connection pipes (154), a plurality of base cable connection pipes (144), and a plurality of cables (180) are configured to be connected.

[0035] The cable connection frame (150) and the cable connection pipe (154) are configured to be positioned on the side of the base cable connection frame (140) equipped with the base cable connection pipe (144).

[0037] At this time, the rotation drive device is configured to be a horizontal rotation drive motor (162) supported by the base frame (120) and having a motor shaft connected to the cable connection frame (150), so that the cable connection frame (150), the cable connection pipe (154), the base cable connection frame (140), the base cable connection pipe (144), and the cable (180) can be rotated in a horizontal direction by the driving of the horizontal rotation drive motor (162).

[0038] The above cable connection frame (150), cable connection pipe (154), base cable connection frame (140), base cable connection pipe (144), and cable (180) are configured to be raised and lowered in the up and down direction by driving a rotational driving device.

[0039] At this time, the rotational drive device includes a moving drive cylinder (172) supported by the base frame (120) and having a cylinder rod arranged in a horizontal direction, and a rotational drive cam (174) coupled to a frame-side shaft (132) provided at the base end of the base connection frame (130) equipped with the base cable connector (144) and connected to the cylinder rod of the moving drive cylinder (172) via a hinge (HG).

[0040] A structure is formed in which the cable (180) is connected to the base cable connector (144) and the cable connector (154) while the cable connection frame (150) and the cable connection pipe (154) are positioned next to the base connection frame (130).

[0041] In the present invention, the cable connection frame (150) is rotated horizontally based on the intermediate hinge connected to the base connection frame (130) by the driving of the moving drive cylinder (172).

[0043] Referring to FIGS. 1 to 8, when the cylinder rod of the moving drive cylinder (172) is extended, the cable connection frame (150), cable connection pipe (154), base connection frame (130), base cable connection pipe (144), and cable (180) are maintained in a downwardly rotated state. Then, when the cylinder rod of the moving drive cylinder (172) is retracted (retracted state) from the extended state, the cable connection frame (150), cable connection pipe (154), base connection frame (130), base cable connection pipe (144), and cable (180) are moved horizontally relative to the base frame (120), the cable (180) is maintained in a state where it is prevented from getting caught on or scraped against the ground. The cable connection frame (150) and the cable connection pipe (154) are maintained in a state where they are rotated upward at a certain angle from the ground, and the cable (180) is prevented from coming into contact with the ground. This prevents the cable (180) from getting caught or scraped on the ground when the cable connection frame (150), the cable connection pipe (154), the base connection frame (130), the base cable connection pipe (144), and the cable (180) are moved horizontally relative to the base frame (120). As a result, the cable (180) can be prevented from twisting or being damaged when the cable (180) moves horizontally.

[0044] In FIG. 9, the state in which the cable connection frame (150), cable connection pipe (154), base connection frame (130), base cable connection pipe (144), and cable (180) are moved horizontally in stages relative to the base frame (120) is illustrated.

[0045] At this time, in the present invention, the cable connection frame (150) is provided with a separate connection frame-side support frame (156), and the connection frame-side support frame (156) is equipped with an upward rotation drive cylinder (158), and the cylinder rod of the upward rotation drive cylinder (158) is connected to the cable connection frame (150) via a hinge, so that when the cylinder rod of the upward rotation drive cylinder (158) is in a retracted state (i.e., when the cylinder rod of the upward rotation drive cylinder (158) is in a retracted state), the cable connection frame (150) is maintained in a state of being rotated upward at a certain angle upward from the ground at the front end.

[0046] Accordingly, the present invention is installed in a facility that controls the position of an electrode rod to promote the process of melting iron by introducing oxygen and water, etc. into an electric furnace (110) in which iron is received to melt iron, and has the effect of preventing the cable (180) through which water and oxygen, etc. are supplied from being twisted or dragged on the ground and damaged by the movement of the frame that supports the movement during the process of controlling the position of the electrode rod through cylinder driving.

[0047] Meanwhile, in the present invention, the cable connection frame (150) is rotated in a horizontal direction by the driving of a horizontal rotation drive motor (162), and the cable connection pipe (154) and the cable (180) supported by the cable connection frame (150) are configured to rotate in a horizontal direction.

[0048] At this time, the pivot link member (142) is composed of a first pivot link member (142A) at the front and a second pivot link member (142B) at the rear.

[0049] The upper end of the first pivot link member (142A) is connected to the base connecting frame (130) via a hinge, the lower end of the first pivot link member (142A) is connected to the base cable connecting pipe (144) via a hinge, the upper end of the second pivot link member (142B) is connected to the base connecting frame (130) via a hinge, the lower end of the second pivot link member (142B) is connected to the base cable connecting frame (140) via a hinge, and auxiliary link members are connected to the base frame (120) and the base cable connecting frame (140) at both ends via auxiliary hinges.

[0050] Accordingly, when the cylinder rod of the moving drive cylinder (172) is in a retracted state, the cable connection frame (150), cable connection pipe (154), base connection frame (130), base cable connection pipe (144), and cable (180) are moved horizontally relative to the base frame (120), and at the same time, the first pivot link member (142A) and the second pivot link member (142B) are also rotated horizontally, thereby having the effect of maintaining the cable (180) more firmly in a state where it is prevented from getting caught or scraped on the ground.

[0051] Meanwhile, FIG. 14 is a front cross-sectional view showing the lower side of the case, panel lifting cylinder, lifting panel, slip guide roll, and cable, which are the main parts of an electrode rod equipment cable guide device according to another embodiment of the present invention; FIG. 15 is a perspective view showing the lower side of the case, panel lifting cylinder, lifting panel, slip guide roll, and cable, which are the main parts of an electrode rod equipment cable guide device according to another embodiment of the present invention; FIG. 16 is a front cross-sectional view schematically showing the structure of the lower side of the case, panel lifting cylinder, lifting panel, slip guide roll, and cable, which are the main parts of an electrode rod equipment cable guide device according to another embodiment of the present invention, as well as the cable detection sensor, upward rotation driving cylinder, and control unit; FIG. 17 is a perspective view showing the structure of the case, panel lifting cylinder, lifting panel, slip guide roll, cable, and grip ring body, which are the main parts of an electrode rod equipment cable guide device according to yet another embodiment of the present invention; FIG. 18 is an enlarged view of the main part of FIG. 17; FIG. 19 is a view showing the case, panel lifting cylinder, lifting panel, and slip guide roll, which are the main parts of an electrode rod equipment cable guide device according to yet another embodiment of the present invention. This is a cross-sectional view showing the structure of the guide roll, cable, and grip ring body.

[0052] Referring to the drawings, the present invention is characterized by further comprising a case (192) installed underground to be positioned below the cable (180), a panel lifting cylinder (194) installed inside the case (192), a lifting panel (196) connected to the cylinder rod of the panel lifting cylinder (194), and a slip guide roll (198) rotatably provided on the lifting panel (196).

[0053] According to the present invention, when the lower part of the bent portion of the cable (180) is in contact with the outer surface of the slip guide roll (198) and the cable (180) moves in a horizontal direction, the slip guide roll (198) is rolled on the lifting panel (196), so that the cable (180) is prevented from dragging or scraping on the ground, and thus more effectively prevents the cable (180) from twisting or burning.

[0054] In addition, the present invention is characterized by further including a cable detection sensor (202) provided on the lifting panel (196) and a control unit (150) connected to the cable detection sensor (202) and connected to control the upward rotation drive cylinder (158).

[0055] According to the present invention, the lowered height of the cable (180) is detected by the cable detection sensor (202) provided on the lifting panel (196), and the upward rotation driving cylinder (158) is operated by the control unit (204) to raise the cable connection frame (150), cable connection pipe (154), base connection frame (130), base cable connection pipe (144), and cable (180) in advance, thereby having the effect of more reliably preventing damage or twisting of the cable (180) caused by the cable (180) coming into contact with the ground and dragging when the cable (180) moves horizontally.

[0056] In addition, the present invention is characterized by further including a grip ring body (212) connecting a plurality of cables (180) and an elastic strap (214) connected between the grip ring bodies (212). At this time, the grip ring body (212) may be configured such that the upper grip set and the lower grip set, in which a semicircular upper and lower split ring piece (212DR) is connected to a half elastic strap piece (214DS), are detachably connected by fasteners such as bolts and nuts, so that the two split ring pieces (212DR) are placed above and below the cable (180), and the upper grip set and the lower grip set are connected above and below the cable (180) by fastening the fasteners to the half elastic strap pieces (214DS) protruding from both ends of the upper grip set and the lower grip set, thereby allowing the grip ring body (212) to grip and support the cable (180).

[0057] Accordingly, the present invention has the effect of preventing the cables (180) from moving independently and getting tangled, as the grip ring body (212) binds the cables (180) together and moves them together.

[0058] In addition, since the elastic strap (214) can be stretched or contracted by appropriate elastic force, it is possible to maintain a suitable distance between the cables (180) to support the cables (180) so that they can move smoothly over a suitable distance, and also to expect the effect of preventing the cables (180) from twisting.
