Description

Technical Field

[0001] This invention relates to the field of calcium carbide furnace technology, and specifically to a copper tube mechanism in the triangular zone of a calcium carbide furnace. Background Technology

[0002] The calcium carbide furnace electrodes are connected to the high-voltage power supply network sequentially via a short grid, transformer, reactor, high-voltage circuit breaker, and disconnector. The short grid refers to a three-phase circuit from the calcium carbide furnace electrode holder to the secondary side of the furnace transformer; it is a crucial part of the electric arc furnace's electrical circuit. The short grid mainly consists of three parts: copper busbars, flexible cables, and copper conduits.

[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 clamps during arrangement. Traditional clamps are divided into integral and split types. Integral clamps use a set of clamps to hold and fix multiple copper tubes. Obviously, when replacing a single copper tube, the entire clamp needs to be removed. Split clamps use multiple sets of clamps to hold and fix multiple copper tubes separately. Obviously, this is more cumbersome to install. Summary of the Invention

[0004] The purpose of this invention is to provide a copper tube mechanism for the triangular zone of an calcium carbide furnace to overcome the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A copper tube mechanism for a triangular zone of an calcium carbide furnace includes multiple copper tubes and a main body for connecting the multiple copper tubes, wherein the main body is provided with:

[0007] The placement slots have multiple structures and are adapted to copper pipes;

[0008] The connecting plates are provided in multiple ways. The multiple connecting plates have a first state in which they are fixed at both ends 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. In the second state, the multiple connecting plates are separated from each other and snap into the corresponding placement slots.

[0009] The copper tube mechanism of the triangular zone of the calcium carbide furnace described above has an L-shaped placement groove, and several placement grooves are symmetrically arranged on the main body.

[0010] In the aforementioned copper tube mechanism for the triangular zone of an calcium carbide furnace, when the copper tube is placed in the placement slot, it first moves along the width of the main body and then moves along the height of the main body.

[0011] The aforementioned copper tube mechanism for the triangular zone of an calcium carbide furnace includes a horizontal plate on the connecting plate and a horizontal groove in the placement slot.

[0012] In the aforementioned copper tube mechanism for the triangular zone of an calcium carbide furnace, the connecting plate is provided with a locking mechanism for locking adjacent connecting plates. When multiple connecting plates are in a first state, multiple locking mechanisms operate, and when multiple connecting plates are in a second state, multiple locking mechanisms release the locking of adjacent connecting plates.

[0013] The aforementioned copper tube mechanism for the triangular zone of an calcium carbide furnace includes a locking mechanism comprising two first locking blocks slidably connected to one side of a connecting plate and two second locking blocks disposed on the other side of the connecting plate, and further comprising an elastic element for forcing the two first locking blocks to move closer to each other.

[0014] In the aforementioned triangular copper tube mechanism of an calcium carbide furnace, two second locking blocks are slidably connected to a connecting plate. Two connecting rings are coaxially rotatably connected to the connecting plate. A first connecting rod and a second connecting rod are fixed on each of the two connecting rings. The first connecting rod and the second connecting rod on one connecting ring are on the same side and are respectively limited and connected to the first locking block and the second locking block on the same side.

[0015] In the aforementioned copper tube mechanism for the triangular zone of an calcium carbide furnace, the end of the first connecting rod furthest from the connecting ring is slidably connected to the first locking block, and the end of the second connecting rod furthest from the connecting ring is slidably connected to the second locking block.

[0016] In the aforementioned triangular copper tube mechanism of an calcium carbide furnace, when the two first locking blocks approach each other based on the elastic element, the two connecting rings passively rotate, so that the two second locking blocks move away from each other based on the action of the elastic element.

[0017] The aforementioned triangular copper tube mechanism for an calcium carbide furnace also includes a drive mechanism for driving the two connecting rings to rotate in opposite directions.

[0018] In the above technical solution, the present invention provides a copper tube mechanism for a triangular zone of an calcium carbide furnace. When multiple connecting plates are in the first state, they form a long strip-shaped whole, which can directly approach the main body and clamp and fix the copper tubes in multiple placement slots, facilitating the connection and positioning of multiple copper tubes. After installation, the multiple connecting plates switch to the second state to separate from each other, and the multiple connecting plates can be inserted into the corresponding placement slots. When it is necessary to inspect or replace a single copper tube, the single connecting plate can be removed to take out the copper tube in the corresponding placement slot, thereby maximizing the inspection efficiency of the copper tubes.

[0031] 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.

[0032] Reference Figure 1-9 This invention provides a copper tube mechanism for a triangular zone of an calcium carbide furnace, including multiple copper tubes 1 and a main body 2 for connecting the multiple copper tubes 1. The main body 2 is provided with placement grooves and connecting plates 3. The placement grooves are multiple and adapted to the copper tubes 1. The connecting plates 3 are provided with multiple connecting plates, which have a first state of being fixed end to end and a second state of being separated from each other. In the first state, the multiple connecting plates 3 form a whole to cooperate with the main body 2 to clamp and fix the multiple copper tubes 1 simultaneously. In the second state, the multiple connecting plates 3 are separated from each other and snap into the corresponding placement grooves.

[0033] Specifically, the copper pipes 1 in the short grid are generally arranged in rows. To fix the position of the copper pipes 1, the prior art uses a connecting structure to fix multiple copper pipes 1 in a row. The connecting structure is generally a clamp, which can be suspended in the air or fixed to the outer wall of a certain position in the calcium carbide furnace to ensure the stable operation of the copper pipes 1 in the short grid. In the prior art, the copper pipe 1 clamp is generally an integral structure, such as the patent document with authorization announcement number CN103200723B entitled "A Copper Pipe Combination Clamp for a Short Grid of a Submerged Arc Furnace", which includes an integral plate and an arc-shaped notch to clamp and fix multiple copper pipes 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 pipes 1 through several sets of plates. The innovation of this invention lies in the provision of a main body 2 and several connecting plates 3. The connecting plates 3 can be connected by a manual or automatic locking structure, as is common in the art, to secure the ends of the connecting plates 3 before installing the copper pipe 1. The main body 2 has placement slots adapted to the copper pipe 1. When the connecting plates 3 are in the first state, they can form a single unit to simultaneously clamp and fix the copper pipe 1. After the connecting plates 3 are inserted into their corresponding placement slots, the locking structures on the connecting plates 3 separate to switch to the second state, allowing the connecting plates 3 to be removed individually for inspection or replacement of a single copper pipe 1. This design improves the inspection efficiency of a single copper pipe 1 while maintaining the efficiency of fixture installation.

[0034] In another embodiment of the present invention, the placement groove is further configured as an L-shape, and several placement grooves are symmetrically arranged on the main body 2. When the copper tube 1 is placed into the placement groove, it first moves along the width of the main body 2, and then moves along the height of the main body 2. Specifically, in the prior art, the arc-shaped notch on the plate is generally semi-circular. Obviously, this requires the copper tube 1 to be initially fixed before the clamp can be operated. In this embodiment, the placement groove is configured as an L-shape. When operating the clamp, the copper tube 1 is first moved into the placement groove along the width 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 multiple placement grooves of the main body 2. Then, the clamping and fixing of the copper tube 1 can be completed by operating multiple connecting plates 3 in the first state.

[0035] Furthermore, the connecting plate 3 is provided with a horizontal plate 4, and the placement groove is provided with a horizontal groove. Specifically, in the above embodiment, after the connecting plate 3 is placed into the placement groove, the connecting plate 3 may move along the thickness direction of the main body 2. For this purpose, the horizontal plate 4 and the horizontal groove structure are provided. Both the horizontal plate 4 and the horizontal groove are provided 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 horizontal plate 4 is inserted into the corresponding horizontal groove. At the same time, the connecting plate 3 is inserted into the placement groove and abuts against the top end of the copper tube 1, thereby restricting the relative position of the main body 2, the copper tube 1 and the connecting plate 3 (the connecting plate 3 can be inserted into the placement groove by means of interference fit to achieve snap-fit).

[0036] Furthermore, the connecting plate 3 is provided with a locking mechanism for engaging adjacent connecting plates 3. When multiple connecting plates 3 are in a first state, multiple locking mechanisms operate; when multiple connecting plates 3 are in a second state, multiple locking mechanisms release the engagement of adjacent connecting plates 3. Specifically, the locking mechanism can be a mechanical snap-fit ​​structure from the prior art. When installing the copper pipe 1, multiple mechanical snap-fit ​​structures are first used to fix the ends of multiple connecting plates 3, and then the multiple connecting plates 3 are simultaneously inserted into the corresponding placement slots. After all multiple connecting plates 3 are inserted into the placement slots, the multiple mechanical snap-fit ​​structures release the engagement of multiple connecting plates 3, allowing the connecting plates 3 to be removed individually for inspection or replacement of the copper pipe 1.

[0037] Preferably, the locking mechanism includes two first locking blocks 5 slidably connected to one side of the connecting plate 3 and two second locking blocks 6 disposed on the other side of the connecting plate 3, and also includes an elastic element 7 for forcing the two first locking blocks 5 to move closer to 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 constructed with openings. The two first locking blocks 5 are slidably connected to the inner wall of the movable cavity along the thickness of the connecting plate 3. The inner wall of the movable cavity is constructed with a protrusion that can limit the position of the first locking blocks 5. In this embodiment, the second locking blocks 6 can be fixed in the movable cavity to cooperate with the slidably disposed first locking blocks 5 to complete the end-to-end fixation of the two adjacent connecting plates 3. The elastic element 7 can be a spring structure, with its two ends fixed to the two first locking blocks 5 respectively, so that the spring forces the two first locking blocks 5 to move closer to each other and abut against the protrusion. With this configuration, when two connecting plates 3 approach each other, the two first locking blocks 5 on the upper side of one connecting plate 3 abut against the two second locking blocks 6 on the lower side of the other connecting plate 3. This causes the two first locking blocks 5 to overcome the elastic force of the elastic element 7 and move away from each other, allowing them to enter the upper movable cavity through the opening in the upper connecting plate 3. The elastic element 7 then allows the first locking blocks 5 to move closer to the second locking blocks 6. Thus, the two connecting plates 3 are secured by a latching structure where the first locking blocks 5 and the second locking blocks 6 adapt to each other. This configuration passively secures multiple connecting plates 3 when they approach each other. Correspondingly, a manual or automatic abutment in the movable cavity can be used to force the two first locking blocks 5 away from each other, releasing the latching of adjacent connecting plates 3 and allowing each connecting plate 3 to be removed individually.

[0038] It should be noted that, as Figure 5 As shown, when the snap-fit ​​structure on the intermediate connecting plate 3 is released (that is, when the two first snap-fit ​​blocks 5 on the intermediate connecting plate 3 move away from each other), the two first snap-fit ​​blocks 5 can be exposed from the opening of the upper connecting plate 3, and the two second snap-fit ​​blocks 6 can be exposed from the opening of the lower connecting plate 3, so that the intermediate connecting plate 3 can be removed from the upper and lower connecting plates 3.

[0039] In another embodiment of the present invention, as an alternative to fixing the second locking block 6 to the connecting plate 3, preferably, two second locking blocks 6 are slidably connected to the connecting plate 3. Two connecting rings 8 are coaxially rotatably connected to the connecting plate 3. A first connecting rod 9 and a second connecting rod 10 are fixed to each of the two connecting rings 8. 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 locking block 5 and the second locking 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 locking block 5, and the end of the second connecting rod 10 away from the connecting ring 8 is slidably connected to the second locking block 6. When the two first locking blocks 5 approach each other based on the elastic element 7, the two connecting rings 8 passively rotate, so that the two second locking blocks 6 move away from each other based on the action of the elastic element 7. Specifically, in the above embodiments, if a connecting plate 3 is to be removed individually, it is necessary not only to operate the snap-fit ​​structure on the connecting plate 3 to release it from the snap-fit ​​of the previous connecting plate 3, but also to operate the snap-fit ​​structure on the next connecting plate 3 to release the snap-fit ​​of the next connecting plate 3 from the previous connecting plate 3, which is quite cumbersome. In this embodiment, the second snap-fit ​​block 6 is slidably connected to the movable cavity along the thickness of the connecting plate 3. A rotating shaft is fixed in the movable cavity, and both connecting rings 8 are rotatably connected to the rotating shaft. The two connecting rings 8 can rotate relative to each other on the rotating shaft. In one connecting cavity, the first snap-fit ​​block 5 on the left and the second snap-fit ​​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); a slider 11 is slidably connected to the first snap-fit ​​block 5 along its length direction, and the slider 11 is hinged to the first connecting rod 9; a sliding rod 12 is constructed on the second snap-fit ​​block 6, and a sliding groove is constructed on the second connecting rod 10, and the sliding rod 12 is slidably connected in the sliding groove; as Figure 3 As shown, when the connecting ring 8 rotates to drive the first locking block 5 on the left side to slide to the left along the movable cavity via the first connecting rod 9 (during which the slider 11 slides appropriately on the first locking block 5), the second locking block 6 on the left side can be driven to slide to the right along the movable cavity via the second connecting rod 10 on the same connecting ring 8 (during which the slide rod 12 slides appropriately in the slide groove). The advantage of this setting is that when the two connecting plates 3 are close to each other, the first locking block 5 and the second locking block 6 can avoid each other, so that the first locking block 5 and the corresponding second locking block 6 can engage (that is, the first locking block 5 on one connecting plate 3 engages with the second locking block 6 on another connecting plate 3), so as to complete the fixation of the beginning and end of multiple connecting plates 3. After multiple connecting plates 3 are inserted into the corresponding placement slots, operating the connecting ring 8 on one connecting plate 3 can drive the first locking block 5 and the second locking block 6 to run synchronously, so as to simultaneously release the engagement of the connecting plate 3 with the upper and lower connecting plates 3. This saves the step of removing a connecting plate 3 and greatly improves the efficiency of inspecting or replacing a single copper tube 1.

[0040] In another embodiment of the present invention, a drive mechanism for driving the two connecting rings 8 to rotate in opposite directions is further included. Specifically, the function of the drive mechanism is the same as that of the manual or automatic abutment in the above embodiment to force the two first locking blocks 5 away from each other. In this embodiment, the drive mechanism can be an abutment that forces the two first connecting rods 9 away from each other, so that when the two first connecting rods 9 move away from each other, they drive the two connecting rings 8 to rotate synchronously and in opposite directions, thereby driving the two first locking blocks 5 and the two second locking blocks 6 to operate in a coordinated manner. Preferably, the drive mechanism operates passively based on the process of the connecting plate 3 being placed into the placement slot, so as to force the two first locking blocks 5 away from each other. That is, in this embodiment, the abutment that forces the two first connecting rods 9 to move away from each other can be passively operated based on the process of the connecting plate 3 being placed into the placement slot. The abutment can extend to the outside of the connecting plate 3 so that it can be triggered by the abutment and the inner wall of the placement slot during the process of the connecting plate 3 being placed into the placement slot, so that the abutment can be operated and force the two connecting rings 8 to rotate in opposite directions. Correspondingly, after the connecting plate 3 is removed from the placement slot, the elastic member 7 can force the two first connecting rods 9 and the abutment to reset.

[0041] Preferably, the driving mechanism includes a movable rod 13 constructed within the connecting plate 3. A movable groove is constructed through the connecting plate 3, and the movable rod 13 is movably disposed within the movable groove (i.e., it can rotate and slide). The end of the movable rod 13 away from the main body 2 protrudes from the connecting plate 3, and a handle 14 is constructed at the end. An arc-shaped plate 15 is constructed on the movable rod 13, and a connecting groove adapted to the arc-shaped plate 15 is constructed on the connecting plate 3. Specifically, the connecting groove communicates with both the movable cavity and the movable groove. The arc-shaped plate 15 is located within the connecting groove. When the arc-shaped plate 15 is removed from the connecting groove, its arc-shaped end can abut against the two first connecting rods 9, forcing them to move away from each other. Under the action of the elastic element 7, the two first locking blocks 5 approach each other, and the two first connecting rods 9 approach each other, thereby forcing the arc-shaped plate 15 into the connecting groove. At this time, the end of the movable rod 13 away from the handle 14 protrudes from the connecting plate 3. During the process of placing the connecting plate 3 into the placement groove... In the middle, the movable rod 13 abuts against 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 abuts against the two first connecting rods 9, thereby forcing the two first locking blocks 5 to move away from each other until the connecting plate 3 is embedded in the placement groove. Then, the two first locking blocks 5 and the two second locking blocks 6 are released from the locking with other connecting plates 3. That is, after multiple connecting plates 3 are placed into the corresponding placement groove, they are passively released from the locking with each other, so that multiple connecting plates 3 are in a separated state, making it easy to remove a single connecting plate 3.

[0042] Preferably, a limiting plate 16 is constructed on the movable rod 13, and an open groove adapted to the limiting plate 16 is constructed on the connecting plate 3. One side of the open groove communicates with the movable groove, and the other side exposes the connecting plate 3. The limiting plate 16 can move a certain distance along the axial direction of the movable rod 13 in the open groove. The inner wall of the groove is constructed with a limiting groove 17 adapted to the limiting plate 16. Specifically, in this embodiment, after the arc plate 15 forces the first locking block 5 and the second locking block 6 to disengage, the arc plate 15 moves out of the connecting groove. At this time, the movable rod 13 can be rotated by the handle 14. Figure 6 As shown, after the arc-shaped plate 15 is removed from the connecting groove, the handle 14 can drive the movable rod 13 to rotate clockwise, so that the arc-shaped plate 15 releases its contact with the first connecting rod 9, allowing the first locking block 5 and the second locking block 6 of the multiple connecting plates 3 to re-engage. That is, the multiple connecting plates 3 are in the first state before installation, switch to the second state after installation, and can switch back to the first state after rotating the handle 14, thereby improving the connectivity between the multiple connecting plates 3. After the arc-shaped plate 15 rotates, it does not correspond to the connecting groove, so that the movable rod 13 cannot move along the axial direction of the movable rod 13. At the same time, when the handle 14 is rotated clockwise, the movable rod 13... 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 setting, the relative position of the connecting plate 3 and the main body 2 can be limited by the rotation of the handle 14, and the engagement between multiple connecting plates 3 can be restored, so that multiple copper tubes 1 can be stably limited on the main body 2. Conversely, if the handle 14 is rotated counterclockwise until the limiting plate 16 touches the inner wall of the open groove, the arc plate 15 corresponds to the connecting groove. At this time, multiple connecting plates 3 can be switched to the second state, and the limiting between the main body 2 and the connecting plate 3 can be released.

[0043] Furthermore, to facilitate the simultaneous removal of multiple connecting plates 3, the position of the handle 14 is restricted in this embodiment, giving the handle 14 a first angle, a second angle, and a third angle, such as... Figure 6As shown, its handle 14 is at a first angle. As the handle 14 rotates clockwise, it rotates sequentially to a second angle and a third angle. A limiting structure, such as a bolt or pin, can be provided on the connecting plate 3 to limit the angle of the handle 14; when the handle 14 is at the first angle, the arc plate 15 corresponds to the connecting groove, and the movable rod 13 can move axially along the movable groove. After the arc plate 15 moves out of the connecting groove, the connecting plate 3 can be removed individually. After the arc plate 15 moves out of the connecting groove, the handle 14 can rotate to the second angle. At the second angle, the arc plate 15 releases its contact with the two first connecting rods 9, allowing the first locking block 5 and the second locking block 6 to engage accordingly. Simultaneously, the limiting plate 16 rotates with the movable rod 13 into the limiting groove 17 to limit the relative positions of the main body 2 and the multiple connecting plates 3. When it is necessary to remove multiple connecting plates 3 simultaneously, the handle 14 is rotated further (e.g., ...). Figure 9 As shown, the handle 14 is between the second and third angles, and the arc plate 15 does not contact the two first connecting rods 9 and still has a certain rotation space, so that the handle 14 can be rotated to the third angle. At this time, the arc plate 15 does not contact the second connecting rod 10, and the limiting plate 16 moves 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 plates 3 can be released, so that the multiple connecting plates 3 can maintain the first state and move out of the placement groove synchronously, which is convenient for the synchronous removal of multiple copper pipes 1.

[0044] It should be noted that the portions of the multiple connecting plates 3 near the copper pipe 1 and the portions of the main body 2 near the copper pipe 1 can be made of insulating and high-temperature resistant materials available in the prior art, such as mica plates, which can provide insulation and high-temperature resistance without affecting the operation of the device.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
