Description

Technical Field

[0001] The invention relates to the technical field of calcium carbide furnaces, and in particular to a triangular copper tube mechanism for a calcium carbide furnace. Background Art

[0002] The electrodes in the calcium carbide furnace are connected to the high-voltage power grid via a short-circuit network, transformer, reactor, high-voltage circuit breaker, and disconnector. The short-circuit network is a three-phase circuit running from the electrode holder to the secondary terminal of the furnace transformer. It is a critical component of the electric arc furnace's electrical circuit. It primarily consists of copper busbars, flexible cables, and copper pipes.

[0003] The arrangement and connection method of copper tubes directly affect the stability and safety of calcium carbide furnace operation. In practical applications, copper tubes need to be fixed by means of clamps during arrangement. Traditional clamps are divided into integral and split types. The integral type refers to a set of clamps that clamp and fix multiple copper tubes. Obviously, when replacing a single copper tube, the entire clamp needs to be removed. The split type refers to a plurality of sets of clamps that clamp and fix multiple copper tubes separately. Obviously, it is more cumbersome to install. Summary of the Invention

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A copper tube mechanism for a triangular area of ​​a calcium carbide furnace, comprising a plurality of copper tubes and a main body for connecting the plurality of copper tubes, wherein the main body is provided with: A placement slot is constructed with multiple slots and adapted to fit the copper pipe; There are multiple connecting plates, and the multiple connecting plates have a first state in which the ends are fixed and a second state in which they are separated from each other. In the first state, the multiple connecting plates form a whole to cooperate with the main body to clamp and fix multiple copper tubes at the same time. In the second state, the multiple connecting plates are separated from each other and stuck in the corresponding placement grooves.

[0006] In the above-mentioned triangular copper tube structure of the calcium carbide furnace, the placement groove is constructed in an L-shape, and a plurality of placement grooves are symmetrically arranged on the main body.

[0007] The above-mentioned copper tube mechanism in the triangular area of ​​a calcium carbide furnace, when the copper tube is placed in the placement groove, first moves along the width of the main body and then moves along the height of the main body.

[0008] The above-mentioned copper tube structure in the triangular area of ​​the calcium carbide furnace is provided with a transverse plate on the connecting plate, and a transverse groove is provided in the placement groove.

[0009] The above-mentioned copper tube mechanism in the triangular area of ​​a calcium carbide furnace is provided with a clamping mechanism for clamping adjacent connecting plates on the connecting plate. When the multiple connecting plates are in the first state, the multiple clamping mechanisms operate; when the multiple connecting plates are in the second state, the multiple clamping mechanisms release the clamping of the adjacent connecting plates.

[0010] The above-mentioned copper tube mechanism in the triangular area of ​​a calcium carbide furnace, the clamping mechanism includes two first clamping blocks slidably connected to one side of the connecting plate and two second clamping blocks arranged on the other side of the connecting plate, and also includes an elastic member for forcing the two first clamping blocks to approach each other.

[0012] In the above-mentioned triangular copper tube mechanism of the calcium carbide furnace, the end of the first connecting rod away from the connecting ring is slidably connected to the first clamping block, and the end of the second connecting rod away from the connecting ring is slidably connected to the second clamping block.

[0013] In the above-mentioned triangular copper tube mechanism of the calcium carbide furnace, when the two first clamping blocks approach each other based on the elastic member, the two connecting rings passively rotate to make the two second clamping blocks move away from each other based on the action of the elastic member.

[0015] In the above technical solution, the present invention provides a copper tube mechanism in the triangular area of ​​a calcium carbide furnace, which forms a long strip-shaped whole when the multiple connecting plates are in the first state, so that it can directly approach the main body and clamp and fix the copper tubes in the multiple placement slots, so as to facilitate the connection and limiting of the multiple copper tubes; after the installation is completed, the multiple connecting plates switch to the second state to separate from each other, and the multiple connecting plates can be stuck in the corresponding placement slots. When a single copper tube needs to be inspected or replaced, the single connecting plate can be removed to take out the copper tube in the corresponding placement slot, so as to maximize the inspection efficiency of the copper tube.

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1-9 An embodiment of the present invention provides a copper tube mechanism in the triangular area of ​​a calcium carbide furnace, comprising a plurality of copper tubes 1, and a main body 2 for connecting the plurality of copper tubes 1, wherein the main body 2 is provided with a placement groove and a connecting plate 3, and the placement groove is constructed in multiple ways and is adapted to the copper tube 1; a plurality of connecting plates 3 are provided, and the plurality of connecting plates 3 have a first state in which the ends are fixed and a second state in which they are separated from each other. In the first state, the plurality of connecting plates 3 form a whole to cooperate with the main body 2 to clamp and fix the plurality of copper tubes 1 at the same time. In the second state, the plurality of connecting plates 3 are separated from each other and stuck in the corresponding placement grooves.

[0021] Specifically, the copper tubes 1 in the short net are generally arranged in rows. In order to fix the position of the copper tubes 1, a connecting structure is selected in the prior art to fix the multiple copper tubes 1 in the row. The connecting structure is generally a clamp. The clamp can be suspended in the air or fixed on the outer wall of a certain position of the calcium carbide furnace to enable the copper tubes 1 in the short net to operate stably. In the prior art, the copper tube 1 clamp is generally an integral structure, such as the patent document with the authorization announcement number CN103200723B and the name "A Short Net Copper Tube Convergence Clamp for Submerged Arc Furnace", which includes an integral plate and an arc-shaped notch to clamp and fix multiple copper tubes 1 at the same time. There is also a split structure in the prior art, that is, an arc-shaped notch is set on a plate to clamp and fix multiple copper tubes 1 through several groups of plates. The innovation of the embodiment of the present invention lies in that a main body 2 and several connecting plates 3 are provided, and a manual clamping structure or an automatic clamping structure in the prior art can be provided between the multiple connecting plates 3 to fix the multiple connecting plates 3 at the head and tail before installing the copper tube 1; a placement groove adapted to the copper tube 1 is constructed on the main body 2, and when the multiple connecting plates 3 are in the first state, the multiple connecting plates 3 can form a whole to clamp and fix the multiple copper tubes 1 at the same time; after the multiple connecting plates 3 are clamped into the corresponding placement grooves, the clamping structures on the multiple connecting plates 3 are separated from each other to switch to the second state, so that the connecting plates 3 can be taken out individually to inspect or replace the single copper tube 1. Such a setting can improve the inspection efficiency of the single copper tube 1 while taking into account the efficiency of the fixture installation.

[0022] In another embodiment provided by the present invention, further, the placement groove is constructed in an L-shape, and a plurality of placement grooves are symmetrically arranged on the main body 2. When the copper tube 1 is placed in the placement groove, it is first moved along the width direction of the main body 2, and then moved along the height direction of the main body 2. Specifically, in the prior art, the arc-shaped notch on the plate is generally semicircular. Obviously, this requires the copper tube 1 to be preliminarily fixed before the clamp can be operated. In this embodiment, the placement groove is constructed in an L-shape. When operating the clamp, the copper tube 1 is first moved into the placement groove along the width direction of the main body 2, and then the copper tube 1 is lowered to the bottom of the placement groove. In this way, multiple copper tubes 1 can be stably placed in the multiple placement grooves of the main body 2 first, and then the multiple connecting plates 3 in the first state are operated to complete the clamping and fixation of the copper tube 1.

[0023] Furthermore, a transverse plate 4 is constructed on the connecting plate 3, and a transverse groove is constructed in the placement groove. Specifically, in the above embodiment, after the connecting plate 3 is placed in the placement groove, the connecting plate 3 may move along the thickness direction of the main body 2. For this purpose, the transverse plate 4 and the transverse groove structure are provided, and the transverse plate 4 and the transverse groove are both arranged along the width direction of the main body 2. When the connecting plate 3 is inserted into the placement groove along the width direction of the main body 2, the transverse plate 4 is inserted into the corresponding transverse groove. At the same time, the connecting plate 3 is inserted into the placement groove and contacts the top end of the copper tube 1, thereby limiting the relative positions of the main body 2, the copper tube 1, and the connecting plate 3 (when the connecting plate 3 is inserted into the placement groove, it can be clamped by an interference fit).

[0024] Furthermore, the connecting plates 3 are provided with a clamping mechanism for clamping adjacent connecting plates 3. When the multiple connecting plates 3 are in a first state, the multiple clamping mechanisms operate. When the multiple connecting plates 3 are in a second state, the multiple clamping mechanisms release the clamping of the adjacent connecting plates 3. Specifically, the clamping mechanism can adopt a mechanical clamping structure in the prior art. When installing the copper tube 1, the multiple connecting plates 3 are first fixed end to end by the multiple mechanical clamping structures, and then the multiple connecting plates 3 are synchronously inserted into the corresponding placement slots. After the multiple connecting plates 3 are all inserted into the placement slots, the multiple mechanical clamping structures release the clamping of the multiple connecting plates 3, so that the connecting plates 3 can be removed individually for inspection or replacement of the copper tube 1.

[0025] Preferably, the clamping mechanism includes two first clamping blocks 5 slidably connected to one side of the connecting plate 3 and two second clamping blocks 6 arranged on the other side of the connecting plate 3, and also includes an elastic member 7 for forcing the two first clamping blocks 5 to approach each other. Specifically, the end of the connecting plate 3 away from the main body 2 is constructed with a movable cavity, and the top and bottom ends of the movable cavity are both constructed with openings. The two first clamping blocks 5 are both slidably connected to the inner wall of the movable cavity along the thickness of the connecting plate 3, and the inner wall of the movable cavity is constructed with a protrusion that can limit the first clamping blocks 5; in this embodiment, the second clamping block 6 can be fixed in the movable cavity to cooperate with the sliding first clamping block 5 to complete the head and tail fixation of the two adjacent connecting plates 3; the elastic member 7 can optionally use a spring structure, and its two ends are respectively fixed on the two first clamping blocks 5, so as to force the two first clamping blocks 5 to approach each other and abut against the protrusion through the spring. With such a configuration, when the two connecting plates 3 approach each other, the two first clamping blocks 5 on the upper side of one connecting plate 3 come into contact with the two second clamping blocks 6 on the lower side of the other connecting plate 3, so that the two first clamping blocks 5 overcome the elastic force of the elastic member 7 and move away from each other, so that the two first clamping blocks 5 can enter the upper movable cavity through the opening of the upper connecting plate 3. Based on the action of the elastic member 7, the first clamping block 5 can be brought close to the second clamping block 6. In this way, the two connecting plates 3 can be fixed by the mutually adapted snap-fit ​​structure of the first clamping block 5 and the second clamping block 6. With such a configuration, the clamping of multiple connecting plates 3 can be passively completed when the multiple connecting plates 3 approach each other. Accordingly, a manual or automatic resisting member is provided in the movable cavity to force the two first clamping blocks 5 to move away from each other, thereby releasing the clamping of the two adjacent connecting plates 3 so that the connecting plates 3 can be taken out individually.

[0026] It should be noted that if Figure 5 As shown, when the clamping structure on the middle connecting plate 3 is released (that is, when the two first clamping blocks 5 on the middle connecting plate 3 are moved away from each other), the two first clamping blocks 5 can be exposed from the opening of the upper connecting plate 3, and the two second clamping blocks 6 can be exposed from the opening of the lower connecting plate 3, so that the middle connecting plate 3 can be removed from the upper and lower connecting plates 3.

[0027] In another embodiment provided by the present invention, as an alternative to the fixing of the above-mentioned second clamping block 6 to the connecting plate 3, preferably, two of the second clamping blocks 6 are slidably connected to the connecting plate 3, and two connecting rings 8 are coaxially rotatably connected to the connecting plate 3, and the two connecting rings 8 are fixed with a first connecting rod 9 and a second connecting rod 10. The first connecting rod 9 and the second connecting rod 10 on one connecting ring 8 are on the same side and are respectively limitedly connected to the first clamping block 5 and the second clamping block 6 on the same side. The end of the first connecting rod 9 away from the connecting ring 8 is slidably connected to the first clamping block 5, and the end of the second connecting rod 10 away from the connecting ring 8 is slidably connected to the second clamping block 6. When the two first clamping blocks 5 approach each other based on the elastic member 7, the two connecting rings 8 passively rotate so that the two second clamping blocks 6 move away from each other based on the action of the elastic member 7. Specifically, in the above embodiment, if one connecting plate 3 is to be taken out separately, it is necessary not only to operate the clamping structure on the connecting plate 3 to release its clamping to the previous connecting plate 3, but also to operate the clamping structure on the next connecting plate 3 to release the clamping of the next connecting plate 3 to the connecting plate 3, which is relatively cumbersome. In this embodiment, the second clamping block 6 is slidably connected in the movable cavity along the thickness of the connecting plate 3, and a rotating shaft is fixed in the movable cavity. The two connecting rings 8 are both rotatably connected to the rotating shaft, and the two connecting rings 8 can rotate relative to each other on the rotating shaft. In one connecting cavity, the first clamping block 5 on the left and the second clamping block 6 on the left are both fixed to the same connecting ring 8 (fixed to the connecting ring 8 by the first connecting rod 9 and the second connecting rod 10 respectively); the first clamping block 5 is slidably connected to a slider 11 along its length direction, and the slider 11 is hinged to the first connecting rod 9; the second clamping block 6 is constructed with a slide bar 12, and the second connecting rod 10 is constructed with a slide groove, and the slide bar 12 is slidably connected in the slide groove; as shown in FIG. Figure 3 As shown, when the connecting ring 8 rotates to drive the first clamping block 5 on the left side to slide to the left along the active cavity through the first connecting rod 9 (in the process, the slider 11 slides adaptively on the first clamping block 5), the second connecting rod 10 on the same connecting ring 8 can drive the second clamping block 6 on the left side to slide to the right along the active cavity (in the process, the slide bar 12 slides adaptively in the slide groove). The advantage of such a setting is that when the two connecting plates 3 approach each other, the first clamping block 5 and the second clamping block 6 can avoid each other so that the first clamping block 5 and the corresponding second clamping block 6 are engaged (that is, the first clamping block 5 on one connecting plate 3 is engaged with the second clamping block 6 on the other connecting plate 3) to complete the end-to-end fixation of the multiple connecting plates 3. After the multiple connecting plates 3 are inserted into the corresponding placement slots, the connecting ring 8 on one connecting plate 3 can be operated to drive the first clamping block 5 and the second clamping block 6 to operate synchronously to synchronously release the engagement of the connecting plate 3 with the upper and lower connecting plates 3. This saves the step of removing one connecting plate 3, greatly improving the efficiency of repairing or replacing a single copper tube 1.

[0028] In another embodiment provided by the present invention, further, a driving mechanism is included for driving the two connecting rings 8 to rotate in opposite directions. Specifically, the function of the driving mechanism is the same as that of the manual or automatic interference member in the above-mentioned embodiment to force the two first clamping blocks 5 to move away from each other. In this embodiment, the driving mechanism can be an interference member that forces the two first connecting rods 9 to move away from each other, so as to drive the two connecting rings 8 to rotate synchronously and in opposite directions when the two first connecting rods 9 move away from each other, thereby driving the two first clamping blocks 5 and the two second clamping blocks 6 to operate in a coordinated manner. Preferably, the driving mechanism is passively operated based on the process of the connecting plate 3 being placed in the placement slot to force the two first clamping blocks 5 to move away from each other. That is, in this embodiment, the resistance member that forces the two first connecting rods 9 to move away from each other can be passively operated based on the process of placing the connecting plate 3 into the placement groove. The resistance member can extend to the outside of the connecting plate 3, so that when the connecting plate 3 is placed into the placement groove, it is triggered by the resistance member and the inner wall of the placement groove, so that the resistance member operates and forces the two connecting rings 8 to rotate in opposite directions. Correspondingly, after the connecting plate 3 is moved out of the placement groove, the two first connecting rods 9 and the resistance member can be forced to reset based on the action of the elastic member 7.

[0029] Preferably, the driving mechanism includes a movable rod 13 constructed in the connecting plate 3, a movable groove is constructed through the connecting plate 3, the movable rod 13 is movably arranged in the movable groove (that is, it can rotate and slide), the end of the movable rod 13 away from the main body 2 is exposed from the connecting plate 3, and a handle 14 is constructed at the end, the movable rod 13 is constructed with an arc plate 15, and the connecting plate 3 is constructed with a connecting groove adapted to the arc plate 15. Specifically, the connecting groove is connected to the movable cavity and the movable groove at the same time, the arc plate 15 is located in the connecting groove, and when the arc plate 15 is moved out of the connecting groove, the arc end of the arc plate 15 can resist the two first connecting rods 9, so as to force the two first connecting rods 9 to move away from each other; under the action of the elastic member 7, the two first blocks 5 approach each other, and the two first connecting rods 9 approach each other, thereby forcing the arc plate 15 to enter the connecting groove, at this time, the end of the movable rod 13 away from the handle 14 is exposed from the connecting plate 3; in the process of the connecting plate 3 being placed in the placement groove In the process, the movable rod 13 contacts the inner wall of the placement groove, so that the movable rod 13 and the arc plate 15 move along the axial direction of the movable rod 13, so that the arc plate 15 approaches and contacts the two first connecting rods 9, thereby forcing the two first clamping blocks 5 to move away from each other, until the connecting plate 3 is embedded in the placement groove, the two first clamping blocks 5 and the two second clamping blocks 6 are released from the clamping of other connecting plates 3, that is, after multiple connecting plates 3 are placed in the corresponding placement grooves, the clamping connection between them is passively released, so that the multiple connecting plates 3 are in a separated state, which is convenient for removing a single connecting plate 3.

[0030] Preferably, a limit plate 16 is constructed on the movable rod 13, and an open groove adapted to the limit plate 16 is constructed on the connecting plate 3. One side of the open groove is connected to the movable groove, and the other side exposes the connecting plate 3. The limit plate 16 can move a certain distance along the axial direction of the movable rod 13 in the open groove, and the inner wall of the placement groove is constructed with a limit groove 17 adapted to the limit plate 16. Specifically, in this embodiment, after the arc plate 15 forces the first clamping block 5 and the second clamping block 6 to release the clamping, the arc plate 15 moves out of the connecting groove. At this time, the movable rod 13 can be driven to rotate by the handle 14, as shown in FIG. Figure 6 As shown, after the curved plate 15 is removed from the connecting groove, the handle 14 can drive the movable rod 13 to rotate clockwise, so that the curved plate 15 releases the interference with the first connecting rod 9, so that the first clamping block 5 and the second clamping block 6 of the multiple connecting plates 3 can be restored to the clamping state, that is, the multiple connecting plates 3 are in the first state before installation, switch to the second state after installation, and can switch to the first state again after rotating the handle 14 to improve the connectivity between the multiple connecting plates 3; after the curved plate 15 is rotated, it does not correspond to the connecting groove, so that the movable rod 13 cannot move axially along the movable rod 13. At the same time, when the handle 14 is rotated clockwise, the movable rod 1 3 can drive the limiting plate 16 to rotate from the open groove to the limiting groove 17, so as to limit the relative position of the connecting plate 3 and the main body 2 through the limiting plate 16. With this arrangement, the relative position of the connecting plate 3 and the main body 2 can be limited by rotating the handle 14, and the clamping connection between the multiple connecting plates 3 can be restored, so that the multiple copper tubes 1 can be stably restricted on the main body 2; on the contrary, if the handle 14 is rotated counterclockwise until the limiting plate 16 contacts the inner wall of the open groove, the arc plate 15 corresponds to the connecting groove, and the multiple connecting plates 3 can be switched to the second state at this time, and the limit between the main body 2 and the connecting plate 3 is released.

[0031] Furthermore, in order to facilitate the simultaneous removal of multiple connecting plates 3, the position of the handle 14 is restricted in this embodiment so that the handle 14 has a first angle, a second angle and a third angle, such as Figure 6When the handle 14 is at the first angle, the curved plate 15 corresponds to the connecting groove, and the movable rod 13 can move axially along the movable groove. After the curved plate 15 is removed from the connecting groove, the connecting plate 3 can be taken out individually. After the curved plate 15 is removed from the connecting groove, the handle 14 can be rotated to the second angle. At the second angle, the curved plate 15 releases the interference with the two first connecting rods 9, so that the first clamping block 5 and the second clamping block 6 can be correspondingly engaged. At the same time, the limiting plate 16 rotates with the movable rod 13 to the limiting groove 17 to limit the relative position of the main body 2 and the multiple connecting plates 3. When multiple connecting plates 3 need to be removed at the same time, continue to rotate the handle 14 (as shown in FIG. Figure 9 As shown, the handle 14 is between the second angle and the third angle, the curved plate 15 does not contact the two first connecting rods 9 and there is still a certain rotation space), so that the handle 14 is rotated to the third angle. At this time, the curved plate 15 does not conflict with the second connecting rod 10, and the limiting plate 16 is moved out of the limiting groove 17. In this way, the restriction on the multiple connecting plates 3 can be maintained and the restriction between the main body 2 and the connecting plate 3 can be released, so that the multiple connecting plates 3 can maintain the first state and be moved out of the placement groove synchronously, which is convenient for the synchronous removal of multiple copper tubes 1.

[0032] It should be noted that the parts of the multiple connecting plates 3 close to the copper tube 1 and the part of the main body 2 close to the copper tube 1 can be made of insulating and high-temperature resistant materials in the existing technology, such as mica boards, which can play an insulating and high-temperature resistant role without affecting the operation of the device.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
