Description

Technical Field

[0001] The utility model relates to the field of hoisting and lengthening processes of electrode barrels in large self-baking electrode type titanium slag electric furnaces in the metallurgical industry, and in particular to a self-unloading special hook device for self-baking electrode barrels in large titanium slag electric furnaces. Background Art

[0002] The self-baking electrode tube of large titanium slag electric furnace is a conductive device used in the smelting process, which is used to conduct current to melt raw materials and produce titanium slag. The electric furnace is a heating furnace that converts the electric energy in the furnace into heat to heat the workpiece. The electric furnace can be divided into resistance furnace, induction furnace, arc furnace, plasma furnace, electron beam furnace, etc. Compared with the fuel furnace, the advantages of the electric furnace are: the atmosphere in the furnace is easy to control; the material is heated quickly; the heating temperature is high; the temperature is easy to control; the production process is easier to realize mechanization and automation; the labor and health conditions are good.

[0003] The electrode barrel is a device on the electric furnace. Its internal electrode connector plays a role in conductivity and tensile strength during the sintering period of the self-baking electrode. The installation position of the electrode barrel is located above the consumable electrode. In the prior art, the electrode barrel needs to be hoisted by a crane just above the consumable electrode. After the basic docking, the worker adjusts the electrode barrel so that the electrode barrel and the consumable electrode are completely engaged. Then the welding worker directly welds the electrode barrel and the consumable electrode.

[0004] The invention patent with the authorization announcement number CN111795580B provides an electrode barrel for a high-power direct current furnace of an iron alloy, including an electrode barrel body, an electrode connecting seat and a hook. The inner surface of the electrode barrel body is fixedly connected with evenly arranged electrode connecting seats; the surface of the electrode connecting seats is provided with heat conduction holes; the upper surface of the electrode barrel body is hung with a hook; the number of hooks is two, and they are symmetrically arranged on the left and right; the two hooks are connected with the same lifting rope; the lower surface of the electrode barrel body is connected with the electrode connecting seat. Since the two hooks in the prior art need to be connected by a lifting rope, manual assistance is required when lifting the motor barrel, and since the stability of the lifting rope is poor, during the lifting process, when the lifting rope shakes, the electrode barrel is easy to swing, and the swing of the electrode barrel is easy to injure the staff below, especially when the electrode barrel is lifted or installed, the unhooking accident will pose a serious threat to the lives of the staff below. Based on this, the prior art still needs to be improved. Utility Model Content

[0029] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in the present invention, it is easy for those skilled in the art to understand that multiple modifications are feasible without actually departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other replacements, modifications, changes and deletions may be made to the design, operating conditions and parameters of the following exemplary embodiments.

[0030] refer to Figure 1 and Figure 2 The electrode cylinder includes a cylinder 13 and a plurality of (for example, 10) ribs 14 arranged inside the cylinder 13 and evenly distributed along the circumference of the cylinder 13. The ribs 14 extend from the inner wall of the cylinder 13 to the central axis of the cylinder 13 along the radial direction of the cylinder 13. One end of the rib 14 is flush with the cylinder 13, and the other end protrudes from the cylinder 13. The rib 14 is provided with a plurality of heat conduction holes 15 arranged in a row along its length direction.

[0031] refer to Figure 3 The utility model provides a self-unloading special hook device for self-baking electrode tubes in large titanium slag electric furnaces, comprising:

[0032] The crossbeam 6 and the two hooks 1 arranged at both ends of the crossbeam 6, the two hooks 1 are oriented in opposite directions, and the two hooks 1 are respectively used to hook into the heat conduction holes 15 on the two preset ribs 14 on the electrode cylinder. The extension lines of the two preset ribs 14 are collinear and pass through the axis of the electrode cylinder, so that the electrode cylinder can maintain balance when it is hoisted on the two hooks 1, and reduce the tilt or shaking amplitude of the electrode cylinder. The crossbeam 6 can rotate in a first direction so that the two hooks 1 are respectively hooked into the two heat conduction holes 15, and can also rotate in a second direction opposite to the first direction so that the two hooks 1 are detached from the two heat conduction holes 15. When in use, each hook 1 on the crossbeam 6 is first placed in the gap between two adjacent ribs 14, and then the crossbeam 6 is rotated so that each hook 1 hooks a heat conduction hole 15 on the rib 14 located on the front side of its rotation direction. When the electrode cylinder is installed, the crossbeam 6 is rotated in the opposite direction and the crossbeam 6 is slightly dropped so that the hook 1 is automatically removed from the heat conduction hole 15. Among them, the electrode cylinder that can be adapted needs to have an even number of ribs 14.

[0033] The self-unloading special hook device for the self-baking electrode barrel of the large titanium slag electric furnace of the present application also includes a suspension part, which is arranged in the middle of the crossbeam 6. The suspension part is used to connect with the electric hoist of the crane, and the crane controls the transfer of the crossbeam 6 through the suspension part. The suspension part is separated from the crossbeam 6 by an insulating member to ensure that the suspension part will not conduct electricity, so as to ensure that the electrode barrel hoisting and lengthening operation can be continuously performed when the electric furnace is in normal production. The material of the crossbeam 6 and the hook 1 is Q235, which is a commonly used structural steel material with good strength, plasticity and welding performance.

[0034] Compared with the prior art, the utility model sets the hook 1 on the crossbeam 6, and the position of the hook 1 can be adjusted by adjusting the posture and / or position of the crossbeam 6, that is, the position of the hook 1 is adjusted by the crossbeam 6, rather than the traditional adjustment with a lifting rope. The electrode barrel can be quickly hoisted and disassembled, and can be widely used in the hoisting and extension of electrode barrels of large self-baking electrode-type titanium slag electric furnaces in the metallurgical industry. The operation is convenient and simple, and the inspection and maintenance are convenient. A lot of manpower and production stoppage time can be saved, costs can be reduced, and greater economic and social benefits can be created.

[0035] In some embodiments, the bottom edge of the hook 1 is chamfered to ensure that the hook can automatically fall off when hoisted into place, eliminating the safety risks of personnel climbing operations. Figure 4 As shown, the left side, right side and middle groove of the lower part of the hook 1 are chamfered. In addition, when making the hook 1, the present application can use the square steel wrapped with cold-rolled plate left on site as the base material for welding and making, which not only saves costs but also completes the task of repairing and reusing waste.

[0036] In some embodiments, reference Figure 3 and Fig. 9The middle part of the crossbeam 6 is provided with at least two through holes 12 arranged along the length direction of the crossbeam 6, and the hanging part includes a U-bolt 7 and a plurality of nuts 2; the opening of the U-bolt faces downward, and the two studs of the U-bolt 7 are respectively inserted into the two through holes 12, and the plurality of nuts 2 are arranged on the studs and located on the upper and lower sides of the crossbeam 6, for connecting each stud to the crossbeam 6. The electric hoist on the crane controls the transfer, lifting and disassembly of the crossbeam 6 and the hook 1 by hooking the U-bolt 7. The material of the U-bolt can also be Q235. Since the U-bolt has good stability, it can prevent unhooking and improve the safety of the operation.

[0037] In some embodiments, reference Figure 3 The insulating member includes two insulating sleeves 5 and two insulating pads 4, each insulating sleeve 5 is arranged in a through hole 12 and sleeved on the outside of the stud; the two insulating pads 4 are respectively arranged on the upper and lower sides of the beam 6 and are located between the nut 2 and the beam 6; refer to Figure 8 The insulating pad 4 is provided with two first mounting holes 9 for allowing two insulating sleeves 5 to be inserted respectively, so as to separate the U-bolt 7 from the non-insulated crossbeam 6 and the hook 1. During the hoisting process or when operating in an electrified environment, if the hook is not insulated, once it comes into contact with a live body, a short circuit or electric shock accident may occur, which will not only damage the equipment but also cause serious harm to the operator. The material of the insulating member in this application is preferably epoxy resin, which has a simple structure and low cost.

[0038] In some embodiments, reference Figure 3 The suspension part further includes two pressing plates 3, each of which is arranged between the insulating pad 4 and the nut 2. The arrangement of the pressing plates 3 can enhance the strength of the entire lifting device and improve safety. Figure 7 The pressing plate 3 is provided with two second mounting holes 10 for allowing two studs to pass through respectively. The aperture of the second mounting hole 10 is smaller than the outer diameter of the insulating sleeve 5, so that the pressing plate 3 abuts against the end of the insulating sleeve 5, further ensuring that the nut 2 and the U-bolt 7 will not conduct electricity.

[0039] In some embodiments, the upper and lower ends of the insulating sleeve 5 extend out of the cross beam 6, and the length of the extended cross beam 6 is the same as the thickness of the insulating pad 4, so that the pressure plate 3 can contact the insulating pad 4 and the insulating sleeve 5 at the same time, improving the compactness and stability of the device.

[0040] In some embodiments, the longitudinal section of the cross beam 6 is a polygon, such as a quadrilateral, a hexagon, etc. Figure 5 The hook 1 is provided with a socket 11 for matching the longitudinal section profile of the cross beam 6 , that is, the hook 1 will not rotate relative to the cross beam 6 and can maintain good contact with the insulating pad 4 and the nut 2 .

[0041] In some embodiments, the position of the hook 1 on the cross beam 6 is adjustable, for example, the hook 1 can be slidably arranged on the cross beam 6 to achieve adjustable position along the length direction of the cross beam 6, so as to be suitable for electrode cylinders of different radial sizes. The hook 1 is also provided with a locking device for connecting the hook 1 with the cross beam 6, so as to lock the hook 1 with the cross beam 6 after the position of the hook 1 is adjusted. Specifically, for example, a threaded hole penetrating the socket 11 is provided on the hook 1, and a locking bolt is screwed into the threaded hole and abutted against the cross beam 6 to achieve locking of the hook 1.

[0042] In some embodiments, reference Figure 3 and Figure 6 There are at least two nuts 2 on the stud below the crossbeam 6, which can increase the reliability of locking and improve the safety of the device.

[0043] In some embodiments, the insulating member further includes a plurality of annular insulating gaskets 8, and the insulating gaskets 8 are used to separate two adjacent components. For example, in the present application, 10 insulating gaskets 8 are provided, 5 of which are sleeved on each stud, and an insulating gasket 8 is provided between the nut 2 and the pressing plate 3, between the insulating gasket 4 and the crossbeam 6, and between two adjacent nuts 2, so as to achieve a good insulation effect and improve the firmness of the device.
