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] A graphitization furnace is a device that converts conductive electrodes into graphite electrodes through high temperatures. Power supply to the graphitization furnace typically involves mounting the electrode clamping mechanism and the aluminum busbar clamping mechanism on a trolley. When power needs to be supplied to the graphitization furnace, the power supply trolley moves to the designated furnace position, and the jacking device controls the motor clamping mechanism to clamp the conductive electrodes, and the busbar clamping mechanism to clamp the power supply aluminum busbar, thereby supplying power to the graphitization furnace.

[0003] In existing technology, a copper column is welded to the side of the column to serve as the base of the busbar clamping mechanism. However, the direct welding of the column and the copper column results in a connection area that is only the bottom periphery of the copper column, leading to a small contact area, high electrical loss, and hindering cost reduction.

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

[0029] 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.

[0030] 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.

[0031] To increase the connection area between the base and column of the busbar clamping mechanism and solve the problems of high power loss and high operating cost of the power transmission vehicle, this utility model proposes a power transmission vehicle 100. The power transmission vehicle 100 includes a conductive mechanism 10, which includes a column 11 and a conductive frame 12. The column 11 is suspended on the conductive frame 12. A plurality of overlapping welded pieces 111 are provided on one side of the column 11. This utility model increases the connection area between the base and column 11 of the busbar clamping mechanism 14 by forming a plurality of overlapping welded pieces 111 on the side of the bottom end of the column 11. The overlapping welded pieces 111 constitute the base of the busbar clamping mechanism 14, thereby reducing power loss and lowering operating costs.

[0032] In one embodiment, the conductive mechanism 10 further includes an electrode clamping mechanism 13 and a busbar clamping mechanism 14. The electrode clamping mechanism 13 and the busbar clamping mechanism 14 are both disposed on the same column 11. Overlapping welding pieces 111 constitute the base of the busbar clamping mechanism 14. The column 11 is connected to the base of the busbar clamping mechanism 14.

[0033] The conductive mechanism 10 includes three columns 11 spaced apart from each other, and three electrode clamping mechanisms 13 are distributed along the length of each column 11 to form a 3*3 square array to correspond to the distribution of conductive electrodes on the graphitization furnace. Each column 11 has a busbar clamping mechanism 14 at its lower end, which clamps the power supply busbar 200 laid on the ground.

[0034] By setting the electrode clamping mechanism 13 and the busbar clamping mechanism 14 on the same column 11, the electrode clamping mechanism 13 and the busbar clamping mechanism 14 share the column 11. The electrode clamping mechanism 13 and the busbar clamping mechanism 14 are electrically connected through the column 11. The power transmission path is short, the structure is simple and compact, the assembly is simple, and the operating cost is low.

[0035] In one embodiment, the conductive frame 12 includes a conductive base 121, a conductive connecting beam 122, and a conductive top seat 123. The two ends of the conductive connecting beam 122 are respectively connected to the conductive base 121 and the conductive top seat 123. The conductive top seat 123 extends downward and is provided with a plurality of mounting plates 1231 arranged from left to right. A set of mounting plates 1231 is fixedly disposed on both sides of the column 11 to increase the contact area between the conductive top seat 123 and the column 11, which can improve the stability of the connection between the two, reduce the contact resistance, and avoid overheating.

[0036] The conductive base 121 is a hollow frame, and several sets of mounting posts 1211 are arranged from left to right inside the conductive base 121. A busbar clamping mechanism 14 is pivotally connected to a set of mounting posts 1211. That is, the busbar clamping mechanism 14 can rotate about the mounting posts 1211 as an axis to adaptively deflect when the busbar clamping mechanism 14 is inserted downward, so as to improve the stability of the connection between the busbar clamping mechanism 14 and the power supply busbar 200.

[0037] In one embodiment, the electrode clamping mechanism 13 includes: an electrode clamping cylinder 131, two clamping arms 132, two electrode clamping plates 133, and a conductive connector 134. One end of each clamping arm 132 is connected to the electrode clamping cylinder 131, and the other end is pivotally connected to the electrode clamping plate 133. One end of the conductive connector 134 is fixedly connected to the column 11, and the other end is laid on the inner side of the electrode clamping plate 133.

[0038] The electrode clamp cylinder 131 provides power for the deflection of the clamping arm 132, and controls the electrode clamping mechanism 13 to be in a clamping or releasing state through external hydraulic pressure. When the electrode clamping mechanism 13 is in the clamping state, the electrode clamp cylinder 131 drives the clamping arms to move closer to each other, causing the two electrode clamping plates 133 to move closer to each other to stably clamp the conductive electrode; when the electrode clamping mechanism 13 is in the releasing state, the electrode clamp cylinder 131 drives the clamping arms 132 to move away from each other to control the two electrode clamps to be set apart.

[0039] A through hole (not shown) is provided on the clamping arm 132, and the positioning post 124 passes through the through hole of the clamping arm 132. The through hole can be set in the middle position or near the electrode clamping plate 133, so that the connection between the positioning post 214 and the clamping arm 132 can serve as a support point. The support point can ensure that the entire electrode clamping mechanism 13 can switch stably and reliably between the clamping state and the release state.

[0040] The clamping arm 132 can pivot horizontally relative to the electrode clamping cylinder 131, and the electrode clamping plate 133 can pivot horizontally under the drive of the clamping arm 132. Furthermore, two spaced-apart bushings 1241 are fixedly mounted on the positioning post 214, and the two bushings 1241 are respectively engaged with the clamping arm 132 from its upper and lower sides. The cross-sectional area of ​​the bushings 1241 is configured to be slightly larger than the through hole to achieve an interference fit between the bushings 1241 and the positioning post 214.

[0041] By setting a positioning post 214 and having the positioning post 2114 locked onto the clamping arm 132 via the bushing 2141, the load brought by external forces in the vertical direction can be overcome, and the clamping arm 132 can be ensured to pivot around the positioning post 214.

[0042] In other embodiments, a cavity (not shown) communicating with the through hole of the bushing 1241 is formed through the side of the clamping arm 132. A coupling (not shown) is provided on the positioning post 124, and the coupling is located in the cavity, thereby fixing the clamping arm 132 to the positioning post 124. Specifically, the coupling can be a centrally perforated disc, fixedly mounted on the positioning post 124.

[0043] In one embodiment, the busbar clamping mechanism 14 includes: a busbar clamping plate 141, a conductive sheet 142, and a busbar clamping cylinder 143, with the busbar clamping cylinder 143 fixedly mounted on the conductive base 121.

[0044] The conductive sheet 142 is fixedly disposed on the inner side wall of the busbar clamp plate 141 and fixedly disposed on the column 11. When the power transmission vehicle 100 is ready to supply power, the busbar clamping cylinder 143 is controlled to bring the two busbar clamp plates 141 of the busbar clamping mechanism 14 closer together until the conductive sheet 142 disposed on the inner side wall of the busbar clamp plate 141 presses against the power transmission busbar 200. When the power transmission vehicle 100 ends, the busbar clamping cylinder 143 is controlled to move the two busbar clamp plates 141 of the busbar clamping mechanism 14 away from each other until the busbar clamping mechanism 14 can be removed from the power transmission busbar 200.

[0045] In summary, compared with the prior art, this utility model increases the connection area between the base of the busbar clamping mechanism 14 and the column 11 by forming a plurality of overlapping welding pieces 111 on the side of the bottom end of the column 11. The overlapping welding pieces 111 constitute the base of the busbar clamping mechanism 14, resulting in low power loss and reduced operating costs.

[0046] 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.
