[0002] The push trolley is a movable device for supplying power to the graphitization furnace. The push trolley is provided with a push mechanism, which has a working state and a non-working state. In the working state, the push mechanism abuts against the power transmission busbar and the conductive electrode of the graphitization furnace respectively; in the non-working state, the push mechanism is separated from the conductive electrode of the graphitization furnace and the power transmission busbar.
[0003] Furthermore, in the scenario of supplying power to the inward series graphitization furnace, reaction walls are provided on the furnace head and furnace tail sides of the graphitization furnace, and a power transmission busbar is provided on the reaction wall, and a branch busbar is extended downward from the power transmission busbar. The pushing mechanism of the power transmission vehicle includes: a frame and two pushing cylinders that can move forward and backward and are arranged on the frame, and a pushing plate is provided on the output end of the two pushing cylinders. When the non-working state is switched to the working state, the two driving cylinders respectively drive their pushing plates to move toward the branch busbar of the power transmission busbar until the two pushing plates respectively abut the conductive electrode and the branch busbar. When the working state is switched to the non-working state, the two driving cylinders drive the pushing plates to separate from the conductive electrode and the branch busbar respectively.
[0004] However, in the process of switching from the working state to the non-working state, the push cylinder is not supported and may move forward and backward relative to the frame due to external force, causing the push plate located in the drive mechanism to collide with the branch busbar or the conductive electrode of the graphitization furnace, thereby resulting in a short service life of the push plate and high maintenance costs. Summary of the invention
[0005] The purpose of the present application is to provide a pushing mechanism and a pushing trolley, which have strong safety and stability and high power transmission efficiency.

The two push plates are respectively used to push the conductive electrode of the graphitization furnace and the branch busbar of the power transmission busbar.
[0009] The limiter is arranged on the frame and extends toward at least one push plate to abut against the push plate.
[0010] In the present application, the push mechanism is provided with a limiter fixed on the frame, and the limiter is arranged toward the push plate of one of the driving oil cylinders. In this way, when the push mechanism switches from the working state to the non-working state, the limiter restricts the driving oil cylinder from continuing to move excessively to one side by pressing the push plate tightly, thereby limiting the movable range of the push cylinder to avoid the push plate on the other side from being scratched and collided, and the push plate has a long service life and low maintenance cost.

[0033] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0034] In addition, the technical features involved in different embodiments 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 are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.
[0035] See also Figure 1 and Figure 2 The present application provides a push trolley 2 for supplying electricity to an inner string graphitization furnace.
[0036] Conductive electrodes are provided on the furnace head and the furnace tail end wall of the internal string graphitization furnace, and a reaction wall is provided between the graphitization furnaces. A power transmission busbar is provided on the reaction wall, and a branch busbar extending downward is provided on the power transmission busbar. Conductive electrodes are provided on the furnace head and the furnace tail end wall of the graphitization furnace. The power transmission trolley 2 is provided between the reaction wall and the graphitization furnace.
[0037] Specifically, the push trolley 2 includes: a push mechanism 1 and a vehicle body 21; the push mechanism 1 is installed on the vehicle body 21. The push mechanism 1 is respectively in contact with the branch busbar and the conductive electrodes of the graphitization furnace to transmit electricity from the power transmission busbar to the inner string graphitization furnace.
[0038] See also Figure 3 , Figure 4 and Figure 5 One specific embodiment of the present application provides a push mechanism to solve the above-mentioned problems of high maintenance cost and low power transmission efficiency. For the convenience of description, the direction of the oil cylinder pushing is defined as the front-to-back direction.
[0039] Specifically, the push mechanism 1 includes: a frame 13, a push cylinder 14 and a limiter 12;
[0040] The push cylinder 14 is installed on the frame 13 so as to be movable forward and backward. Two push plates 11 are respectively provided at the two output ends of the push cylinder 14. The two push plates 11 are respectively used to push the conductive electrode of the graphitization furnace and the branch busbar of the power transmission busbar;
[0041] It should be noted that the frame 13 is a general reference to a portion of the mechanical structure of the pushing trolley 2 , and can be understood as a local structure for installing the pushing mechanism 1 , or simply refers to the pushing trolley 2 .
[0042] The limiter 12 is disposed on the frame 13 and extends toward at least one push plate 11 to abut against the push plate 11 .
[0043] In the present application, the push mechanism 1 is provided with a stopper 12 fixed on the frame 13, and the stopper 12 is arranged toward the push plate 11 of one push cylinder 14. In this way, when the push mechanism 1 is switched from the working state to the non-working state, the stopper 12 restricts the push cylinder 14 from continuing to move excessively to one side by pressing against the push plate 11, thereby limiting the movable range of the push cylinder 14 to prevent the push plate 11 on the other side from being scratched and collided.
[0044] Specifically, the stopper 12 is disposed toward the graphitization furnace to abut against the push plate 11 on one side of the graphitization furnace.
[0045] See also Figure 1 to Figure 5 In one specific embodiment, the state of the push trolley 2 is divided into a working state and a non-working state:
[0046] In the working state, the pushing trolley 2 moves to the designated furnace position, and the conductive electrodes and reaction walls of the graphitization furnace are respectively provided on both sides of the moving direction of the pushing mechanism 1. A power transmission busbar is provided on the reaction wall, and a branch busbar is provided at the downward extension of the power transmission busbar.
[0047] When the pushing mechanism 1 is working, the pushing plates 11 on both sides are driven by the pushing cylinder 14 to respectively push the conductive electrode and the branch busbar tightly, thereby supplying electricity to the graphitization furnace.
[0048] In a non-working state, the pushing plates 11 on both sides of the pushing mechanism 1 are separated from the conductive electrodes and the branch busbars respectively.
[0049] When the working state is switched to the non-working state, the pushing cylinder 14 drives the pushing plates 11 on both sides to reset. During the resetting process, since the pushing cylinder 14 is not supported, it moves forward and backward relative to the frame 13. If the pushing plate 11 connected to the pushing cylinder 14 has moved to the position in the non-working state before the pushing cylinder 14 is reset, the limiter 12 fixed on one side of the frame 13 will press the pushing plate 11 in the direction of the conductive electrode, thereby limiting the further movement of the pushing cylinder 14.
[0050] In an alternative embodiment, two limiters 12 may be used. The two limiters 12 are respectively disposed on both sides of the frame 13 at the same time, or are disposed only on one side facing the reaction wall.
[0051] In this way, the position of the push cylinder 14 can be limited on both sides simultaneously by the limiter 12, thereby further limiting the moving range of the push cylinder.
[0052] See also Figure 3 , Figure 4 and Figure 5The frame 13 is provided with a plurality of cross beams, longitudinal beams and support beams 131, the support beam 131 is arranged between two adjacent cross beams, and the push cylinder 14 and the limiter 12 are arranged parallel to each other;
[0053] In this embodiment, the limiter 12 is arranged at the center of the support beam 131 of the frame 13, and the four push cylinders 14 are installed on the inner sides of the longitudinal beams on both sides of the frame 13 with the limiter 12 as the center, and are distributed at the four vertices of the rectangle in a rectangular shape.
[0054] In this way, it can be ensured that after the push plate 11 is reset, the limiter 12 can just limit the push cylinder 14 from continuing to move, and it can be ensured to the greatest extent that the limiter 12 can just complete the limiting effect.
[0055] Optionally, the positions of the limiter 12 and the push cylinder 14 can be determined according to the actual situation, such as square distribution, trapezoidal distribution, and circular distribution.
[0056] Optionally, the limiter 12 is disposed on the frame 13 so as to be movable forward and backward, or the limiter 12 is fixed on the frame 13 .
[0057] See also Figure 3 to Figure 6 The limiter 12 is movable forward and backward and is disposed on the frame 13 . The limiter 12 includes a buffer portion 121 , a support portion 122 and a positioning nut 123 . The buffer portion 121 is disposed at one end of the support portion 122 .
[0058] In a specific embodiment, the buffer portion 121 abuts against the push plate 11 in the direction of the conductive electrode of the graphitization furnace when the push mechanism 1 is not in operation, so as to buffer the reset push plate 11. Optionally, the buffer portion 121 is designed as a cylinder.
[0059] The support portion 122 is fixed to the center of the support beam 131 of the frame 13 , the stopper 12 passes through the support beam 131 , and the buffer portion 121 is disposed at one end of the support portion 122 facing the conductive electrode of the graphitization furnace.
[0060] The positioning nut 123 is installed on the support part 122 and is located on the back side of the support beam 131 to limit the position of the limiter 12. The cross-sectional area of the positioning nut is larger than that of the support part 122 to prevent the force of the push cylinder 14 moving forward and backward from being too large when the push cylinder 14 is reset, causing the limiter 12 to slide out of the frame.
[0061] In another embodiment, the buffer portion 121 is fixed to the push plate 11, and the support portion 122 is telescopically fixed to the support beam 131 of the frame 13. The buffer portion 121 is arranged at one end of the support portion 122 facing the conductive electrode of the graphitization furnace. The limiter 12 can move synchronously with the push cylinder 14 through the extension and retraction of the support portion 122.
[0062] In other alternative embodiments, the shape of the buffer portion 121 can be set to be a cuboid, a circle or other shapes. The support portion can also be a rectangle, a trapezoid or other shapes.
[0063] Of course, the number, shape, size and position of the limiter 12 can be set according to the use requirements and are not limited to the specific limitations of this embodiment.
[0064] See also Figure 6 , Figure 7 and Figure 8 The support beam 131 includes: a beam body 1311, a guide member 1312 and a guide tube 1313;
[0065] The beam body 1311 of the support beam 131 is formed by three hard plates spliced in an “I” shape, and an opening is provided below the middle position thereof. The guide member 1312 is plugged into the back plate of the beam body 1311 along the opening.
[0066] The interior of the guide member 1312 is hollow, and the guide tube 1313 runs through the guide member 1312 , and the limiter 12 is arranged in the guide tube 1313 .
[0067] Two ribs are respectively disposed on both sides of the guide member 1312 to strengthen the mechanical strength of the support beam 131 .
[0068] See also Figure 1 and Figure 4 Some embodiments of the present application further provide a pushing trolley 2, comprising: a vehicle body 21 and a pushing mechanism 1 of any of the above-mentioned embodiments arranged on the vehicle body 21.
[0069] The pushing trolley 2 of the present application can avoid the situation in which the pushing plates 11 on both sides are reset asynchronously during the resetting process, causing the pushing cylinder 14 to move radially, thereby preventing the pushing plates 11 from resetting normally and further affecting the movement of the pushing trolley 2, so that the trolley can work stably and reliably.
[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled 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 list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection created by this application.
