Abstract
Description
Technical Field
[0001] The present application relates to the technical field of power transmission equipment for graphitizing furnaces, and in particular to a pushing mechanism and a pushing trolley. Background Art
[0002] The pusher trolley is a removable device that supplies power to the graphitization furnace. It is equipped with a push mechanism that has two operating states: an active state and an inactive state. In the active state, the pusher mechanism abuts the power busbar and the graphitization furnace's conductive electrodes. In the inactive state, the pusher mechanism is separated from the graphitization furnace's conductive electrodes and the power busbar.
[0003] Furthermore, in the scenario of supplying power to an in-line graphitization furnace, reaction walls are provided on both 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 provided downwardly extending 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 provided 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 this application is to provide a pushing mechanism and a pushing trolley with strong safety and stability and high power transmission efficiency.
[0006] To achieve the above objectives, this application adopts the following technical means:
[0007] In a first aspect of the present application, a pushing mechanism is provided, comprising: a frame, a pushing cylinder, and a limiter;
[0008] The push cylinder is installed on the frame so as to be movable forward and backward. Two push plates are provided at the two output ends of the push cylinder. The two push plates are used to push the conductive electrodes of the graphitization furnace and the branch busbars of the power transmission busbar respectively.
[0009] The limiter is arranged on the frame and extends toward at least one push plate to abut against the push plate.
[0010] In this application, the push mechanism is designed by fixing a limiter on the frame and positioning the limiter toward the push plate of one of the drive cylinders. This way, when the push mechanism switches from an operating state to a non-operating state, the limiter presses against the push plate to prevent the drive cylinder from moving excessively to one side, thereby limiting the movable range of the push cylinder and preventing the push plate on the other side from being scratched or collided. This results in a long service life and low maintenance costs for the push plate.
[0011] Optionally, the limiter is configured to extend toward one side of the graphitization furnace and is arranged parallel to the push cylinder.
[0012] Optionally, the limiter includes: a buffer portion and a support portion, and the buffer portion is provided at one end of the support portion for abutting against the push plate.
[0013] Optionally, the support portion is fixed to the frame, or the support portion is movably arranged on the frame.
[0014] Optionally, the limiter further includes a positioning nut, which is arranged on the supporting portion.
[0015] Optionally, a support beam is provided on the frame, and the limiter is provided on the support beam.
[0016] Optionally, the frame further includes a longitudinal beam and a plurality of transverse beams arranged on the longitudinal beam, and the support beam is located between two adjacent transverse beams.
[0017] Optionally, the support beam includes: a beam body and a guide member, an opening is formed in the beam body, and the guide member is inserted into the back plate of the beam body along the opening.
[0018] Optionally, a guide tube is provided in the guide member, and the limiter is inserted in the guide tube.
[0019] In another aspect of the present application, a pushing trolley is provided, comprising: a vehicle body and any one of the above-mentioned pushing mechanisms provided on the vehicle body.
[0020] The pushing trolley of the present application adopts any of the above-mentioned pushing mechanisms. During the process of switching the pushing mechanism from the working state to the non-working state, the limiter restricts the driving cylinder from continuing to move excessively to one side by pressing the pushing plate tightly, thereby limiting the movable range of the pushing cylinder to avoid the pushing plate on the other side from being scratched or collided. The pushing plate has a long service life and low maintenance cost, and the operation of the pushing trolley is stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.
[0034] In addition, the technical features involved in the 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 having the same or similar functions.
[0035] See also Figure 1 and Figure 2 The present application provides a push trolley 2 for supplying power to an inner string graphitization furnace.
[0036] Conductive electrodes are installed on both the furnace head and tail end walls of the internal string graphitization furnace, and a reaction wall is installed between the graphitization furnaces. The reaction wall is equipped with a power busbar, which is equipped with downward-extending branch busbars. Conductive electrodes are installed on both the furnace head and tail end walls of the graphitization furnace. A power supply trolley 2 is located between the reaction wall and the graphitization furnace.
[0037] Specifically, the pushing trolley 2 includes a pushing mechanism 1 and a trolley body 21. The pushing mechanism 1 is mounted on the trolley body 21. The pushing mechanism 1 contacts the branch busbar and the conductive electrodes of the graphitization furnace respectively, so as to transmit electricity from the power transmission busbar to the internal string graphitization furnace.
[0038] See also Figure 3 、 Figure 4 and Figure 5 One specific embodiment of the present application provides a pushing 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 pushing mechanism 1 includes: a frame 13, a pushing cylinder 14 and a limiter 12;
[0040] The pushing cylinder 14 is mounted on the frame 13 so as to be movable forward and backward. Two pushing plates 11 are provided at the two output ends of the pushing cylinder 14. The two pushing plates 11 are used to push the conductive electrodes of the graphitization furnace and the branch busbars of the power transmission busbar respectively.
[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 pushing mechanism 1 is provided with a stopper 12 fixed on a frame 13, and the stopper 12 is arranged toward the pushing plate 11 of one pushing cylinder 14. In this way, when the pushing mechanism 1 switches from the working state to the non-working state, the stopper 12 prevents the pushing cylinder 14 from moving excessively to one side by pressing against the pushing plate 11, thereby limiting the movable range of the pushing cylinder 14 and preventing the pushing plate 11 on the other side from being scratched or 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 Figures 1 to 5 In one 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. 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. The reaction wall is provided with a power transmission busbar, 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 cylinder 14 drives the pushing plates 11 on both sides to respectively push the conductive electrode and the branch busbar, thereby supplying power to the graphitization furnace.
[0048] In the 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, the pushing cylinder 14 is not subjected to any supporting force, and thus 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 provided on both sides of the frame 13, or are provided 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 movement range of the push cylinder.
[0052] See also Figure 3 、 Figure 4 and Figure 5, a plurality of cross beams, longitudinal beams and support beams 131 are provided on the frame 13, the support beam 131 is provided between two adjacent cross beams, and the push cylinder 14 and the limiter 12 are provided 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 in a rectangular shape at the four vertices of the rectangle.
[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 arranged 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 Figures 3 to 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 one 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, thereby providing a buffer for the reset push plate 11. Optionally, the buffer portion 121 is cylindrical.
[0059] The support portion 122 is fixed to the center of the support beam 131 of the frame 13 , the limiter 12 passes through the support beam 131 , and the buffer portion 121 is provided 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 provided at one end of the support portion 122 facing the conductive electrode of the graphitizing furnace. The limiter 12 can move synchronously with the push cylinder 14 through the extension and contraction 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 limiters 12 can be set according to usage 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 joined in an I-shape. An opening is provided below the middle portion thereof, and 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 passes through the guide member 1312 , and the limiter 12 is arranged in the guide tube 1313 .
[0067] Two ribs are provided on both sides of the guide member 1312 to enhance 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 provided 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, thereby affecting the movement of the pushing trolley 2, and making the trolley work stably and reliably.
[0070] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
