Description

Technical Field

[0001] This utility model relates to the field of graphitized power transmission equipment technology, and more specifically, to a power transmission vehicle. Background Technology

[0002] In traditional power transmission vehicles, the busbar clamping mechanism requires a push cylinder to control the hydraulic pressure to control the clamping and releasing of the busbar clamping mechanism when clamping the power transmission busbar.

[0003] However, each busbar clamping mechanism has two busbar clamps, and each busbar clamp requires two push cylinders to control its movement. Such a busbar clamping mechanism has an overly complex structure, high operating costs, and is not conducive to reducing the redundancy of the power transmission car.

[0004] Therefore, it is urgent to propose a new technical solution to address the problem. Utility Model Content

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of this utility model; based on the embodiments of this utility model, those skilled in the art can make similar improvements without departing from the spirit of this utility model, but cannot make all other embodiments obtained without creative effort, therefore this utility model is not limited to the specific embodiments disclosed below.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Please see Figures 1 to 8To address the problems of complex structure and high operating costs of traditional power transmission vehicles 100, this utility model provides a power transmission vehicle 100, which includes a conductive mechanism 10, comprising a plurality of busbar clamping mechanisms 11, with a series hydraulic cylinder 20 connecting adjacent busbar clamping mechanisms 11. Compared with the prior art, this utility model simplifies the overall structure of the power transmission vehicle 100 and reduces its redundancy by sharing a single series hydraulic cylinder 20 between adjacent busbar clamping mechanisms 11.

[0036] Please see Figures 2 to 7 In one embodiment, the busbar clamping mechanism 11 adopts a clamping type busbar clamp. That is, a portion of the busbar clamping mechanism 11 has a busbar clamping cylinder 111 and a series cylinder 20 on both sides of the busbar clamping plate 112. The clamping and releasing of the busbar clamping mechanism 11 are controlled by controlling the hydraulic pressure of the busbar clamping cylinder 111 and the series cylinder 20. Another portion of the busbar clamping mechanism 11 has a series cylinder 20 on both sides, and the clamping and releasing of the busbar clamping mechanism 11 are controlled by the hydraulic pressure of the two series cylinders 20.

[0037] In traditional power transmission vehicles, the busbar clamping mechanism 11 has two push cylinders, but these two push cylinders are dedicated to this busbar clamping mechanism 11. This makes the structure of the busbar clamping mechanism 11 too complex and the operating cost too high.

[0038] Please see Figure 4 In one embodiment, the busbar clamping mechanism 11 adopts a clamping type busbar clamp, and a series hydraulic cylinder 20 is connected between two adjacent busbar clamping mechanisms 11. That is, two adjacent busbar clamping mechanisms 11 share the series hydraulic cylinder 20, thereby simplifying the overall structure of the busbar clamping mechanism 11 and reducing the cost of use.

[0039] Specifically, please refer to Figure 5 The busbar clamping mechanism 11 includes: a busbar clamping plate 112, a conductive sheet 113, a busbar clamping cylinder 111, and a series cylinder 20. The busbar clamping cylinder 111 is disposed on the outer side of the busbar clamping plate 112, and the conductive sheet 113 is disposed on the inner side wall of the busbar clamping plate 112. The conductive mechanism 10 also includes a conductive base 12. The busbar clamping cylinder 111 is fixedly disposed on the conductive base 12, and the series cylinder 20 is connected between two adjacent busbar clamping mechanisms 11.

[0040] Furthermore, this embodiment has three busbar clamping mechanisms 11, arranged from left to right as a first busbar clamping mechanism, a second busbar clamping mechanism, and a third busbar clamping mechanism. A busbar clamping cylinder 111 is provided on the left side of the first busbar clamping mechanism. A series cylinder 20 is connected between the first busbar clamping mechanism and the second busbar clamping mechanism. A series cylinder 20 is also connected between the second busbar clamping mechanism and the third busbar clamping mechanism. Another busbar clamping cylinder 111 is provided on the right side of the third busbar clamping mechanism.

[0041] Optionally, the two busbar clamps 112 are arranged opposite to each other, one busbar clamp 112 is connected to the busbar clamping cylinder 111, and the other is connected to the series cylinder 20. Alternatively, both busbar clamps 112 are connected to the series cylinder 20.

[0042] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment, the conductive mechanism 10 further includes a conductive frame 13 and a column 14. The conductive frame 13 is fixedly suspended on the column 14, the conductive sheet 113 is connected to the column 14, and the electrode clamping mechanism 15 and the busbar clamping mechanism 11 are both located on the same column 14.

[0043] By setting the electrode clamping mechanism 15 and the busbar clamping mechanism 11 on the same column 14, the electrode clamping mechanism 15 and the busbar clamping mechanism 11 share the column 14. The electrode clamping mechanism 15 and the busbar clamping mechanism 11 are electrically connected through the column 14. The power transmission path is short, the structure is simple and compact, the assembly is simple, and the operating cost is low.

[0044] Specifically, when the power transmission vehicle 100 is ready to supply power to the graphitization furnace, the control of the busbar clamping cylinder 111 and the series cylinder 20 causes the two busbar clamping plates 112 of the busbar clamping mechanism 11 to move closer to each other until the conductive sheet 113 on the inner side wall of the busbar clamping plate 112 presses against the power transmission busbar 200. When the power transmission vehicle 100 finishes supplying power, the control of the busbar clamping cylinder 111 and the series cylinder 20 causes the two busbar clamping plates 112 of the busbar clamping mechanism 11 to move away from each other until the busbar clamping mechanism 11 can be removed from the power transmission busbar 200.

[0045] Please see Figures 1 to 3 In one embodiment, the conductive mechanism 10 further includes a driving member 16 and an electrode clamping mechanism 15. The driving member 16 is used to drive the electrode clamping mechanism 15 to rise and fall, so as to drive the busbar clamping mechanism 11 to rise to separate from the power supply busbar 200 or to fall to dock with the power supply busbar 200.

[0046] Specifically, please refer to Figure 2Typically, the power supply busbar 200 has several branch busbars, the number of which is the same as the number of busbar clamping mechanisms 11. However, in actual operation, after the drive unit 16 lowers the conductive mechanism 10, it is difficult for the busbar clamping mechanism 11 to dock with the branch busbars. The power supply trolley 100 may have difficulty stopping accurately at the current furnace position, and the busbar clamping mechanism 11 and branch busbars may experience some deformation during use. There may also be some deviations in the installation of the busbar clamping mechanism 11. All these factors will affect the docking of the busbar clamping mechanism 11 with the branch busbars.

[0047] Therefore, please refer to Figures 5 to 7 In this embodiment, at least a portion of the conductive sheet 113 is made elastic. When the driving member 16 moves the conductive mechanism 10 downwards, if there is a slight deviation between the busbar clamping mechanism 11 and the power supply busbar 200, the deformation of the conductive sheet 113 can adaptively change the position of the busbar clamping plate 112, thereby allowing the busbar clamping plate 112 of the busbar clamping mechanism 11 to smoothly clamp the branch busbars of the power supply busbar 200. Furthermore, the restoration of elastic deformation of the conductive sheet 113 will cause it to tend to press against the branch busbars, making the connection between the busbar clamping mechanism 11 and the power supply busbar 200 more stable.

[0048] Specifically, please refer to Figure 7 The conductive sheet 113 includes a clamping portion 1131, an elastic portion 1132, and a connecting portion 1133. The two ends of the elastic portion 1132 are connected to the clamping portion 1131 and the connecting portion 1133, respectively. The elastic portion 1132 is elastic, allowing for fine-tuning of the shape of the conductive sheet 113. The clamping portion 1131 is a rigid structure, increasing the contact area between the conductive sheet 113 and the branch busbar. The connecting portion 1133 is also a rigid structure, facilitating the installation of the conductive sheet 113 onto the column 14 by the operator.

[0049] In practice, a portion of copper column is usually welded to the side of column 14 to serve as the base of busbar clamping mechanism 11 (not shown in the figure). However, direct welding of column 14 and copper column results in a connection area that is only around the bottom perimeter of the copper column, leading to a small contact area, high electrical loss, and high operating costs.

[0050] Please see Figure 5 In this embodiment, the bottom end of the column 14 forms several overlapping welded pieces 141 on its side, and the overlapping welded pieces 141 constitute the base of the busbar clamping mechanism 11. The connection area between the overlapping welded pieces 141 and the column 14 is the sum of the sidewall areas of the welded pieces 141. Its connection area is much larger than the contact area between the column 14 and the entire copper column, resulting in low power loss and low operating cost.

[0051] Of course, the column 14 and the base can also be integrally formed, without being limited to the specific limitations of the specific implementation method.

[0052] Please see Figure 8 In one embodiment, the conductive base 12 is a hollow frame, and the conductive base 12 has several sets of mounting posts 121 arranged from left to right. A busbar clamping mechanism 11 is pivotally connected to a set of mounting posts 121. That is, the busbar clamping mechanism 11 can rotate about the mounting posts 121 as an axis to adaptively deflect when the busbar clamping mechanism 11 is inserted downward, thereby improving the stability of the connection between the busbar clamping mechanism 11 and the power supply busbar 200.

[0053] Please see Figure 8 In one embodiment, the conductive mechanism 10 further includes a conductive connecting beam 17 and a conductive top seat 18. The two ends of the conductive connecting beam 17 are connected to the conductive base 12 and the conductive top seat 18, respectively. The conductive top seat 18 extends downward and is provided with several sets of mounting plates 181 arranged from left to right. A set of mounting plates 181 is fixedly disposed on both sides of the column 14 to increase the contact area between the conductive top seat 18 and the column 14, thereby improving the stability of the connection between the two and reducing the contact resistance to avoid overheating.

[0054] In summary, compared with the prior art, this utility model simplifies the overall structure of the power transmission vehicle 100 and reduces the redundancy of the power transmission vehicle 100 by sharing a single series hydraulic cylinder 20 with two adjacent busbar clamping mechanisms 11.

[0055] Obviously, the above embodiments are merely examples for the detailed description of this utility model, and are not intended to limit the implementation. This utility model can be implemented in many other ways different from those described herein. Although embodiments of this utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make other modifications and variations based on the above description, and such modifications and variations still fall within the protection scope defined by the appended claims.
