Abstract
Description
Technical Field
[0001] The present application relates to the technical field of aluminum electrolysis equipment, and in particular to a slot wire fastening structure. Background Art
[0002] The cell pressure measured by the cell controller is a crucial parameter for controlling aluminum electrolytic cell production. The tightness of the cell pressure wire at the cell bottom directly affects the accuracy of the cell pressure measurement, playing a crucial role in electrolytic production. Due to the unique characteristics of the cell bottom, the cell pressure wire inspection and tightening operation requires the use of an insulated ladder or other climbing equipment, which is extremely inconvenient to carry. Utility Model Content
[0003] An embodiment of the present application provides a slot pressing wire fastening structure for improving the slot pressing wire inspection and fastening operation in the related art, which requires the use of insulating ladders and other climbing tools during the operation process, which is extremely inconvenient to carry.
[0004] The present invention provides a groove wire fastening structure, comprising:
[0005] A hand-held rod having an inner cavity and a first opening and a second opening communicating with the inner cavity, wherein the first opening and the second opening are respectively located on opposite sides of the hand-held rod in a longitudinal direction;
[0006] The fastener includes two clamping jaws and a rotating shaft arranged opposite to each other, the clamping jaws including a connecting portion and a clamping portion, the connecting portions of the two clamping jaws being located in the inner cavity and being sleeved on the rotating shaft, and the clamping portions of the two clamping jaws passing through the first opening and being located outside the handle;
[0007] The adjusting part includes an adjusting rod and an adjusting handle, one end of the adjusting handle is located in the inner cavity, and the other end of the adjusting handle passes through the second opening and is located outside the hand-held rod; the adjusting rod is located in the inner cavity, one end of the adjusting rod is sleeved on the rotating shaft, and the other end of the adjusting rod is adjustably connected to the adjusting handle so that the adjusting rod and the adjusting handle can be relatively close to or far away.
[0008] The grooved wire fastening structure of the embodiment of the present application is designed with an adjustable rod and an adjustable handle so that the rod and the handle can be relatively moved closer or farther away. Thus, when the rod and the handle move closer together, the rotating shaft can be driven to move toward the inside of the handle, causing the clamping claw to retract into the inner cavity of the handle; and when the rod and the handle move away from each other, the rotating shaft can be driven to move toward the outside of the handle, causing the clamping claw to extend outward from the handle. In other words, the degree to which the clamping claw extends out of the handle can be adjusted by moving the rod and the handle closer or farther away.
[0009] The opening angle of the two clamping jaws is constrained by the inner wall of the first opening formed by the handlebar. If the two clamping jaws extend further out of the handlebar, the opening angle will be larger due to the constraint of the inner wall of the first opening formed by the handlebar. If the two clamping jaws extend less out of the handlebar, the opening angle will be smaller due to the constraint of the inner wall of the first opening formed by the handlebar. In other words, the relative extension of the two clamping jaws can be controlled by the extent to which the clamping jaws extend out of the handlebar, thereby enabling the fastening screw on the groove pressure line to be clamped.
[0010] Specifically, before clamping the fastening screw on the groove press line, the adjusting rod and the adjusting handle are adjusted so that the adjusting rod and the adjusting handle are relatively separated. This increases the opening angle of the two clamping jaws under the constraint of the inner wall of the first opening formed by the handle bar, making it easier to wrap around the fastening screw. After the two clamping jaws wrap around the fastening screw, the adjusting rod and the adjusting handle are adjusted so that the adjusting rod and the adjusting handle are relatively close to each other. This decreases the opening angle of the two clamping jaws under the constraint of the inner wall of the first opening formed by the handle bar, allowing the two clamping jaws to clamp the fastening screw. Thereafter, the handle bar is rotated to tighten the loose fastening screw on the groove press line through the two clamping jaws.
[0011] The clamping parts of the two clamping jaws are designed to be on one side of the length direction of the hand-held rod. In this way, when the operator uses the groove pressing line fastening structure to check or tighten the groove pressing screws, he only needs to hold the other side of the length direction of the hand-held rod, which can avoid high-altitude operations and maintain a safe working distance.
[0012] In some of the schemes, the adjusting rod is threadedly connected to the adjusting handle, the inner wall of the second opening formed by the hand-held rod is provided with one of a limiting protrusion and a limiting groove, and the adjusting handle is provided with the other of a limiting protrusion and a limiting groove, the limiting protrusion is provided in the limiting groove, and the limiting groove is arranged around the circumference of the adjusting handle.
[0013] Based on the above scheme, when rotating the adjustment handle, due to the constraints of the limiting groove and the limiting protrusion, the adjustment handle can only rotate relative to the hand-held rod, while the adjustment rod threadedly connected to the adjustment handle can rise or fall under the constraints of the clamping claw and the first opening, so as to achieve the relative approach or distance of the adjustment rod relative to the adjustment handle.
[0014] In some of the solutions, a hand-holding ring is provided on the portion of the adjustment handle located outside the hand-holding rod.
[0015] Based on the above solution, it is convenient for the operator to hold the hand-held ring to adjust the adjustment rod and the adjustment handle, and it is more convenient to apply force.
[0016] In some solutions, one end of the adjusting rod close to the rotating shaft includes two connecting plates, which are respectively located on opposite sides of the two clamping jaws along the direction of the rotating shaft, and the two connecting plates are both sleeved on the rotating shaft.
[0017] Based on the above solution, the adjustment rod is reliably connected to the rotating shaft on both sides of the two clamping jaws, which can improve the smoothness of the movement of the rotating shaft driven by the adjustment rod. In addition, the two connecting plates are located on opposite sides of the two clamping jaws to avoid obstruction of the relative movement of the two clamping jaws.
[0018] In some of the solutions, a guide groove is provided on the inner wall of the handle bar, the guide groove extends along the length direction of the handle bar, and a portion of the rotating shaft is located in the guide groove.
[0019] Based on the above solution, the design of the guide groove can guide the movement of the rotating shaft driven by the adjusting rod, thereby preventing the rotating shaft from deviating during the movement.
[0020] In some of the solutions, the inner wall of the handle is chamfered at the first opening.
[0021] Based on the above solution, the chamfered design can make the clamping jaws move in and out of the first opening smoother.
[0022] In some of the solutions, the clamping portions of the two clamping jaws bulge in directions away from each other.
[0023] Based on the above solution, the two clamping jaws can enclose and form a better covering area, which can increase the contact area with the fastening screw and improve the slipping phenomenon during the process of twisting the handheld rod.
[0024] In some of the solutions, the clamping portions of the two clamping jaws have relatively close clamping surfaces, and the clamping surfaces include a plurality of planes arranged in sequence at an angle.
[0025] Based on the above solution, the slipping phenomenon that occurs during the twisting of the handheld rod can be further improved.
[0026] In some of the solutions, the extending directions of the clamping portions of the two clamping jaws are bent relative to the length direction of the handle.
[0027] Based on the above solution, since the position of the groove pressure line fastening screw is higher, the clamping part is designed to be bent relative to the length direction of the hand-held rod. If the hand-held rod is slightly tilted, the clamping part can be roughly horizontal, which is roughly consistent with the shape of the horizontal fastening screw, and can better adapt to the fastening screw and facilitate tightening.
[0028] In some of the solutions, the slot-pressing wire fastening structure is an insulating member.
[0029] Based on the above solution, since the slot pressure wire carries high voltage, the slot pressure wire fastening structure is designed as an insulating part, which can avoid power outage of the slot pressure wire during operation, avoid the safety risk of electric shock, and improve the safety of operators.

[0039] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
[0040] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0041] See also Figure 1 and Figure 2The embodiment of the present application provides a groove-pressing wire fastening structure 1, which includes a handle 10, a fastener 20, and an adjusting member 30. The handle 10 has an inner cavity 11 and a first opening 12 and a second opening 13 communicating with the inner cavity 11. The first opening 12 and the second opening 13 are located on opposite sides of the handle 10 in the longitudinal direction. The fastener 20 includes two clamping jaws 21 and a rotating shaft 22 arranged opposite to each other. The clamping jaws 21 include a connecting portion 211 and a clamping portion 212. The connecting portions 211 of the two clamping jaws 21 are located in the inner cavity 11 and are both sleeved on the rotating shaft 22. The clamping portions 212 of the two clamping jaws 21 pass through the first opening 12 and are located outside the handle 10. The adjusting member 30 includes an adjusting rod 31 and an adjusting handle 32. One end of the adjusting handle 32 is located in the inner cavity 11, and the other end of the adjusting handle 32 passes through the second opening 13 and is located outside the hand-held rod 10; the adjusting rod 31 is located in the inner cavity 11, and one end of the adjusting rod 31 is sleeved on the rotating shaft 22, and the other end of the adjusting rod 31 is adjustably connected to the adjusting handle 32 so that the adjusting rod 31 and the adjusting handle 32 can be relatively close to or far away from each other.
[0042] The embodiment of the present application is designed to be adjustably connected to the adjustment rod 31 and the adjustment handle 32, so that the adjustment rod 31 and the adjustment handle 32 can be relatively moved closer or farther away. In this way, when the adjustment rod 31 and the adjustment handle 32 move closer to each other, the rotation shaft 22 can be driven to move toward the inside of the handle 10, so that the clamping jaws 21 are retracted into the inner cavity 11 of the handle 10; and when the adjustment rod 31 and the adjustment handle 32 move away from each other, the rotation shaft 22 can be driven to move toward the outside of the handle 10, so that the clamping jaws 21 are extended toward the outside of the handle 10. In other words, the degree to which the clamping jaws 21 extend out of the handle 10 can be adjusted by adjusting the adjustment rod 31 and the adjustment handle 32 to move closer or farther away from each other.
[0043] The opening angle of the two clamping jaws 21 is constrained by the inner wall of the first opening 12 formed by the handle bar 10. If the two clamping jaws 21 extend significantly beyond the handle bar 10, the opening angle will be larger under the constraint of the inner wall of the first opening 12 formed by the handle bar 10. If the two clamping jaws 21 extend less beyond the handle bar 10, the opening angle will be smaller under the constraint of the inner wall of the first opening 12 formed by the handle bar 10. In other words, the relative extension of the two clamping jaws 21 can be controlled by the extent to which the clamping jaws 21 extend beyond the handle bar 10, thereby enabling the tightening of the fastening screw on the groove press line.
[0044] Specifically, before clamping the fastening screw on the groove press line, the adjusting rod 31 and the adjusting handle 32 are adjusted so that the adjusting rod 31 and the adjusting handle 32 are relatively far apart, so that the opening angle of the two clamping jaws 21 is larger under the constraint of the inner wall of the first opening 12 formed by the hand-held rod 10, and the fastening screw is easily wrapped. After the two clamping jaws 21 wrap around the fastening screw, the adjusting rod 31 and the adjusting handle 32 are adjusted so that the adjusting rod 31 and the adjusting handle 32 are relatively close to each other, so that the opening angle of the two clamping jaws 21 is smaller under the constraint of the inner wall of the first opening 12 formed by the hand-held rod 10, and the two clamping jaws 21 can clamp the fastening screw. Thereafter, by rotating the hand-held rod 10, the loose fastening screw on the groove press line can be tightened by the two clamping jaws 21.
[0045] The clamping portion 212 of the two clamping jaws 21 is designed to be on one side of the length direction of the hand-held rod 10. In this way, when the operator uses the groove pressing wire fastening structure 1 to check or tighten the groove pressing screws, he only needs to hold the other side of the length direction of the hand-held rod 10, which can avoid high-altitude operations and maintain a safe distance for operation.
[0046] The length of the handle 10 can be approximately 1m to 2m. By properly designing the length of the handle 10, the operator can avoid climbing to a height when inspecting or tightening the groove-pressed screws using the groove-pressed wire fastening structure 1, thereby maintaining a safe working distance. Optionally, the length of the handle 10 can be 1m, 1.25m, 1.5m, 1.75m, 2m, etc., without limitation.
[0047] The adjustment rod 31 is designed to include an adjustment handle 32 that is partially located outside the hand-held rod 10, which facilitates the operator to adjust the adjustment rod 31 and the adjustment handle 32 by operating the adjustment handle 32. For example, in some exemplary embodiments, the portion of the adjustment handle 32 that is located outside the hand-held rod 10 is provided with a hand-held ring 321. The operator can hold the hand-held ring 321 to adjust the adjustment rod 31 and the adjustment handle 32, making it more convenient to apply force.
[0048] The adjustable connection between the adjustment rod 31 and the adjustment handle 32 can be: the adjustment rod 31 and the adjustment handle 32 are threadedly connected, the inner wall of the hand-held rod 10 forming the second opening 13 is provided with one of a limiting protrusion and a limiting groove, and the adjustment handle 32 is provided with the other of the limiting protrusion and the limiting groove, the limiting protrusion being provided within the limiting groove, and the limiting groove being provided around the circumference of the adjustment handle 32. In this way, when the adjustment handle 32 is rotated, due to the constraints of the limiting groove and the limiting protrusion, the adjustment handle 32 can only rotate relative to the hand-held rod 10, while the adjustment rod 31, which is threadedly connected to the adjustment handle 32, can rise or fall under the constraints of the clamping jaw 21 and the first opening 12, so as to achieve the relative approach or distance of the adjustment rod 31 relative to the adjustment handle 32.
[0049] See Figure 1 and Figure 2The first opening 12 can be a substantially strip-shaped hole, and the two clamping jaws 21 are relatively distributed along the length of the first opening 12, so that they can be roughly spread apart or brought closer together in the length direction of the strip-shaped hole to adjust the opening angle of the two clamping jaws 21. The two clamping jaws 21 can roughly contact the inner wall of the strip-shaped hole in the width direction of the strip-shaped hole, and will be constrained by the inner wall of the first opening 12 and will not rotate relative to the handle 10, making the movement of the clamping jaws 21 more controllable.
[0050] The inner wall of the handle 10 is provided with a chamfer 15 at the first opening 12, so that the clamping jaw 21 can be moved in and out of the first opening 12 more smoothly. If the first opening 12 is a strip hole, the inner wall of the handle 10 can be designed to be provided with chamfers 15 at the two short sides of the strip hole.
[0051] See Figure 1 and Figure 2 The inner wall of the handle 10 is provided with a guide groove 14, which extends along the length of the handle 10, and the rotating shaft 22 is located in the guide groove 14. The design of the guide groove 14 can guide the movement of the rotating shaft 22 driven by the adjustment rod 31, thereby preventing the rotating shaft 22 from deviating during the movement.
[0052] Furthermore, two guide grooves 14 may be provided on the inner wall of the handle 10 , and the two guide grooves 14 are respectively located on opposite sides of the rotating shaft 22 , and both ends of the rotating shaft 22 are respectively located in the two guide grooves 14 , so that the movement of the rotating shaft 22 is more stable.
[0053] It is understandable that the extension length of the guide slot 14 along the length direction of the handle 10 can be reasonably designed to control the movement stroke of the rotating shaft 22 in the guide slot 14 and thus control the extent to which the clamping jaw 21 can extend out of the handle 10.
[0054] The adjusting rod 31 is sleeved on the rotating shaft 22 and can be: Figure 2 The end of the adjustment rod 31 near the rotating shaft 22 includes two connecting plates 311. The two connecting plates 311 are located on opposite sides of the two clamping jaws 21 along the direction of the rotating shaft 22, and both connecting plates 311 are sleeved onto the rotating shaft 22. In this way, the adjustment rod 31 is securely connected to the rotating shaft 22 on both sides of the two clamping jaws 21, which can improve the smoothness of the movement of the rotating shaft 22 driven by the adjustment rod 31. The two connecting plates 311 are located on opposite sides of the two clamping jaws 21, which can avoid obstruction of the relative movement of the two clamping jaws 21.
[0055] The adjusting rod 31 can be a hollow rod to reduce the weight of the groove pressing wire fastening structure 1 and reduce the workload of the operator. Of course, the adjusting rod 31 can also be a solid rod, which is not limited to this.
[0056] See Figure 1 The clamping parts 212 of the two clamping jaws 21 bulge in the direction away from each other, so that the two clamping jaws 21 can enclose a better covering area, increase the contact area with the fastening screw, and improve the slipping phenomenon during the process of twisting the hand-held rod 10.
[0057] Furthermore, the clamping portions 212 of the two clamping jaws 21 have relatively close clamping surfaces 2121 , and the clamping surfaces 2121 include a plurality of planes sequentially arranged at an angle to further improve the slipping phenomenon during the process of twisting the handle 10 .
[0058] In an exemplary embodiment, see Figure 2 The clamping parts 212 of the two clamping jaws 21 can extend along the length direction of the handle 10, so that the design difficulty of the clamping jaws 21 can be simplified and the manufacturing cost can be reduced. This structure is more suitable for fastening screws in a vertical state. In another exemplary solution, refer to Figure 3 The extension direction of the clamping part 212 of the two clamping jaws 21 is bent relative to the length direction of the hand-held rod 10. Since the position of the groove pressure line fastening screw is higher, the clamping part 212 is designed to be bent relative to the length direction of the hand-held rod 10. If the hand-held rod 10 is slightly tilted, the clamping part 212 can be roughly horizontal, which is roughly consistent with the shape of the horizontal fastening screw, and can better adapt to the fastening screw and facilitate tightening.
[0059] It should be noted that whether the clamping portion 212 of the two clamping jaws 21 extends along the length direction of the handle bar 10 or is bent relative to the length direction of the handle bar 10 and the specific degree of bending, etc., can be determined in combination with the specific shape of the fastening screw, and the embodiment of the present application does not limit this.
[0060] In some embodiments, the two clamping jaws 21 can be designed as insulating members. Because the cable clamp carries high voltage, designing the clamping jaws 21 as insulating members can avoid powering down the cable during operation, reducing the risk of electric shock and improving operator safety. Furthermore, the cable clamp securing structure 1 can be an insulating member to further enhance operator safety.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
