Description

Technical Field

[0001] This application relates to the technical field of power supply equipment for graphitization furnaces, and particularly to a cable adjusting mechanism, a pushing trolley, and a rectifying trolley. Background Art

[0002] A rectifying trolley is a movable device for supplying power to a graphitization furnace. Usually, the rectifying trolley is provided with a pushing mechanism and an electrical short network that are electrically connected to each other. When the rectifying trolley supplies power to the graphitization furnace, the pushing mechanism abuts against the conductive electrode on the end wall of the graphitization furnace, and heat will be transferred from the conductive electrode to the pushing mechanism, resulting in a reduced service life of the pushing mechanism.

[0003] In order to improve the service life of the push plate in the pushing mechanism, a water-cooled cable is connected between the electrical short network and the pushing mechanism. The water-cooled cable can not only achieve the electrical connection between the pushing mechanism and the electrical short network, but also the circulating cooling water can cool the pushing mechanism during the power supply process of the rectifying trolley, so it is widely used.

[0004] However, the water-cooled cable will be bent during the operation of the rectifying trolley, resulting in blocked circulation of the cooling water or even breakage of the pipeline, and the temperature control effect of the pushing mechanism is poor.

[0005] In view of this, a new technical solution is needed to solve the above technical problems. Summary of the Invention

Detailed implementation manners

[0030] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0031] In addition, the technical features involved in different implementation manners of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0032] Embodiment 1

[0033] Some specific implementation manners of the present application provide a cable adjusting mechanism 100. The cable adjusting mechanism 100 is used to adjust the curvature radius of a water-cooled cable. Of course, the cable adjusting mechanism 100 can also be used for other flexible objects, such as cables and wires.

[0034] Please refer to Figure 1 , the cable adjusting mechanism 100 includes: a frame 10, a driving member 30 and a roller shaft 20. The driving member 30 and the roller shaft 20 are both arranged on the frame 10; the driving member 30 is connected to the roller shaft 20 to drive the roller shaft 20 to pivot.

[0035] The water-cooled cable is configured to abut against the roller shaft 20. The outer surface of the roller shaft 20 is a non-smooth surface. Thus, there is a certain static friction force between the roller shaft 20 and the water-cooled cable, so that the pivoting of the roller shaft 20 can drive the water-cooled cable to move.

[0036] The cable adjustment structure of the present application drives the roller shaft 20 to pivot by setting the driving member 30, thereby driving the water-cooled cable abutted against the roller shaft 20 until the curvature radius of the water-cooled cable falls within a suitable range. The water path in the water-cooled cable is smooth, the water-cooled cable is not easily broken, has a long service life, and the cooling effect on the pushing mechanism is stable and reliable.

[0037] In addition, the roller shaft 20 is relatively fixed to the output shaft of the driving member 30, so that the roller shaft 20 remains stationary under the push of the water-cooled cable, and the position of the water-cooled cable is stable and reliable.

[0038] In some embodiments of the present application, the frame 10 includes: a base 11 and at least a pair of mounting seats 12 provided on the base 11, and both ends of the roller shaft 20 are respectively passed through a pair of mounting seats 12.

[0039] The base 11 provides a mounting position for the mounting seats 12.

[0040] Perforations are formed on the mounting seats 12, and both ends of the roller shaft 20 are configured to have a slightly smaller radial radius to fit the perforations of the mounting seats 12. The roller shaft 20 can rotate in the perforations under the driving action of the driving member 30. Without the control of the driving member 30, the roller shaft 20 is not pushed by the water-cooled cable and has reliable stability.

[0041] In this embodiment, only a pair of mounting seats 12 are used. In other embodiments, two pairs of mounting seats 12 are arranged at intervals in the front-rear direction, and two roller shafts 20 and four driving members 30 are arranged in cooperation with the two pairs of mounting seats 12.

[0042] The two driving members 30 can cooperate to adjust the water-cooled cable to reduce the difficulty of cable adjustment. Exemplarily, the two driving members 30 are two first driving motors 31 and two second driving motors 32. When the curvature radius of the water-cooled cable is too large, the first driving motor 31 drives one of the roller shafts 20 to rotate counterclockwise, and the second driving motor 32 drives the other roller shaft 20 to rotate clockwise. Conversely, when the curvature radius of the water-cooled cable is too small, the first driving motor 31 drives one of the roller shafts 20 to rotate clockwise, and the second driving motor 32 drives the other roller shaft 20 to rotate counterclockwise. By arranging the first driving motor 31 or the second driving motor 32 at both ends of the roller shaft 20, the pivoting of the roller shaft 20 is more stable and reliable.

[0043] Please continue to refer to Figure 2 , further, the mounting seats 12 are two vertical plates 121 arranged at intervals along the axial direction of the roller shaft 20, the driving member 30 is arranged on the vertical plates 121, and the output shaft of the driving member 30 extends downward between the two vertical plates 121.

[0044] Specifically, the driving member 30 is inverted and arranged at the upper end of the vertical plate 121, so that the output shaft of the driving member 30 falls between the two vertical plates 121. The vertical plates 121 play a protective role for the output shaft of the driving member 30, so that the driving member 30 is less interfered by the outside world and operates stably and reliably.

[0045] Embodiment 2

[0046] In actual work, a number of water-cooled cables need to be carried on the roller shaft 20. The bending degrees of the water-cooled cables in the free state are different. In the traditional technology, only relying on the rotation of the roller shaft 20, the range of curvature adjustment for the water-cooled cables is limited, and it is possible that a part of the water-cooled cables are still in a state of excessive bending for a long time.

[0047] See Figure 2 , in an embodiment of the present application, a cable adjusting mechanism 100 is provided, and the difference from Embodiment 1 is that: the driving member 30 is pivotally arranged on the mounting seat 12.

[0048] Specifically, when the driving member 30 pivots clockwise relative to the mounting seat 12, the height of the roller shaft 20 decreases. When the driving member 30 pivots counterclockwise relative to the mounting seat 12, the height of the roller shaft 20 increases.

[0049] Compared with the driving member 30 being fixedly arranged on the mounting seat 12, the driving member 30 is pivotally connected to the mounting seat 12. By controlling the pivoting amplitude of the driving member 30, the position of the roller shaft 20 is changed, and the bending radius of the water-cooled cable is adjusted in cooperation with the roller shaft 20. The adjustment is more flexible and the adjustment amplitude is larger, so that all water-cooled cables can be within a suitable curvature radius range.

[0050] Further, the mounting seat 12 further includes: a base 11 and a connecting shaft 122 arranged on the base 11. A pivoting portion is provided at the bottom end of the driving member 30, and the pivoting portion is sleeved on the connecting shaft 122 so that the driving member 30 pivots relative to the mounting seat 12.

[0051] In a specific embodiment, the output shaft of the driving member 30 is pivotally connected to the roller shaft 20.

[0052] By adjusting the pivoting amplitude of the cable fixing bracket 40 relative to the output shaft of the driving member 30, the position of the roller shaft 20 can be further adjusted, thereby increasing the adjustment range of the water-cooled cable.

[0053] The output shaft of the driving member 30 is pivotally provided with a cable fixing bracket 40, and the roller shaft 20 is arranged on the cable fixing bracket 40 so that the roller shaft 20 pivots relative to the output shaft of the driving member 30.

[0054] The pivotal connection between the mounting seat 12 and the driving member 30 can be realized by two components, namely the connecting shaft 122 and the pivoting portion. The structure is simple and the connection is stable and reliable.

[0055] Further, the cable fixing bracket 40 includes a clamping portion 41 and a clamping groove 42 fixedly connected to the clamping portion 41; the clamping portion 41 is pivotally connected to the output shaft of the driving member 30.

[0056] The clamping portion 41 is fixedly connected to the output shaft of the driving member 30. Of course, the clamping portion 41 can also be configured to be detachably connected to the output shaft of the driving member 30. The clamping groove 42 can be a C-shaped groove, and a clamp or a cable tie can be used to reinforce the water-cooled cable.

[0057] Embodiment 3

[0058] Please refer to Figure 3 , in some embodiments of the present application, a pushing trolley 200 is provided, including a vehicle body, a pushing mechanism, and the cable adjusting mechanism 100 of any one of the above embodiments.

[0059] The vehicle body is provided with a support frame, and the support frame is provided with a plurality of pushing mechanisms and the cable adjusting mechanism 100. A pressing plate is provided at the end of the pushing mechanism, and the conductive electrode of the graphitization furnace is pushed against by driving the pressing plate.

[0060] One end of the water-cooled cable is connected to the pressing plate of the pushing mechanism, and the other end is connected to the power transmission busbar 500. While the water-cooled cable supplies power to the pressing plate, it also conveys cooling water to the pressing plate to keep the pressing plate at a normal working temperature.

[0061] In the cable adjusting structure of the present application, by setting the driving member 30 and driving the roller 20 to pivot by the driving member 30, the water-cooled cable abutted against the roller 20 is driven to move until the curvature radius of the water-cooled cable falls within a suitable range. The water path in the water-cooled cable is smooth, the water-cooled cable is not easily broken, has a long service life, and the cooling effect on the pushing mechanism is stable and reliable.

[0062] Embodiment 4

[0063] Please refer to Figure 4 , in some embodiments of the present application, a rectifying trolley 400 is provided, including a trolley body 300 and a pushing trolley 200, and the pushing trolley 200 is provided with the cable adjusting mechanism 100 of any one of the above embodiments.

[0064] The rectifying trolley is provided with a power supply mechanism, and a water-cooled cable is connected between the power supply mechanism and the pushing mechanism of the pushing trolley 200. Thus, the power supply mechanism transmits electricity to the pushing mechanism through the water-cooled cable. Among them, one end of the water-cooled cable is connected to the pressing plate of the pushing mechanism, and the other end is connected to the power transmission busbar 500.

[0065] The cable adjustment structure of the present application drives the roller shaft 20 to pivot by setting the driving member 30, thereby driving the water-cooled cable abutted against the roller shaft 20 to move until the curvature radius of the water-cooled cable falls within a suitable range. The water path in the water-cooled cable is smooth, the water-cooled cable is not easily broken, has a long service life, the cooling effect on the pushing mechanism is stable and reliable, and the operation of the rectifier trolley 400 is stable and reliable.

[0066] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
