Among them, the graphitization furnace has a power supply state and a non-power supply state. When in the power supply state, the furnace head trolley and the furnace tail trolley are controlled to dock with the graphitization furnace at the same time. When in the non-power supply state, the furnace head trolley and the furnace tail trolley are controlled to separate from the graphitization furnace.

[0003] Among them, a reaction wall is provided on one side of the tail of the graphitization furnace. In the power supply state, one end of the pushing device of the tail trolley pushes the graphitization furnace, and the other end pushes the reaction wall to balance the reaction force given by the graphitization furnace to the tail trolley. In the non-power supply state, the pushing device of the tail trolley is separated from the graphitization furnace and the reaction wall.

[0004] However, in the related art, when the furnace tail trolley needs to switch between the power transmission state and the non-power transmission state, it is necessary to manually rotate the support shaft of the jacking device to control the output stroke of the jacking device, which increases the time cost during the power transmission process and reduces the power transmission efficiency of the power transmission trolley.

[0005] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

[0023] Specifically, in the power supply state, the pushing shaft of the driving member of the pushing device is driven to move toward the conductive electrode of the graphitization furnace until it abuts against the conductive electrode. The conductive electrode pushes the pushing device back, so that the loader moves toward the reaction wall until one end of the loader pushes against the reaction wall, so that the pushing device supports the graphitization furnace and the reaction wall respectively;

[0037] 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.

[0038] 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.

[0039] The push trolley is a movable device used to supply power to the graphitization furnace.

[0040] The graphitization furnace has a power supply state and a non-power supply state. When in the power supply state, the furnace head trolley and the furnace tail trolley are controlled to dock with the graphitization furnace at the same time. When in the non-power supply state, the furnace head trolley and the furnace tail trolley are controlled to separate from the graphitization furnace.

[0041] Among them, a reaction wall is provided on one side of the tail of the graphitization furnace. In the power supply state, one end of the pushing device of the tail trolley pushes the graphitization furnace, and the other end pushes the reaction wall to balance the reaction force given by the graphitization furnace to the tail trolley. In the non-power supply state, the pushing device of the tail trolley is separated from the graphitization furnace and the reaction wall.

[0042] Usually, the push cylinder is fixed to the frame, and a support part rotatably connected to the push cylinder is provided on the push cylinder. At present, the operator manually rotates the support part to push or leave the reaction wall by a handle, which takes a long time and leads to low power transmission efficiency.

[0043] See also Figure 1 and Figure 2 One specific embodiment of the present application provides a push trolley to solve the problem of low power transmission efficiency. The push trolley can be used on the furnace head side of the graphitization furnace as a furnace head push trolley; it can also be used on the furnace tail side of the graphitization furnace as a furnace tail push trolley.

[0044] A push trolley, comprising: a push device 1, a conductive push plate 2, a loader 3 and a vehicle body 5;

[0045] The pushing device 1 is movable forward and backward and is arranged on the loader 3 . One end of the pushing device 1 is connected to the conductive push plate 2 . The conductive push plate 2 is used to abut against the conductive electrode of the graphitization furnace. The loader 3 is fixed to the vehicle body 5 .

[0046] The pushing device 1 is provided with a pushing portion 11 and a supporting portion 12, and the pushing portion 11 is fixedly connected to the conductive pushing plate 2;

[0047] The pushing portion 11 and the supporting portion 12 can both perform telescopic movement. The pushing portion 11 is fixedly connected to the conductive pushing plate 2, and the supporting portion 12 is used to push the reaction wall.

[0048] In the present application, the pushing device 1 is arranged on the loader 3 so as to be movable forward and backward, and the pushing device 1 is controlled to move relative to the loader 3, so as to realize the switching of the pushing trolley between the power transmission state and the non-power transmission state. Specifically, in the power transmission state, the trolley controls the pushing part 11 of the pushing device 1 to move toward the conductive electrode of the graphitization furnace. In the process of the conductive push plate 2 pushing the conductive electrode, the pushing device 1 that can move forward and backward inside the loader 3 will be affected by the reaction force and move backward under the action of the reaction force. At the same time, the pushing device 1 controls the support part 12 to move toward the reaction wall to realize the support of the conductive push plate 2; in the non-power transmission state, the pushing part 11 of the pushing device 1 is controlled to move away from the conductive electrode of the graphitization furnace, and the support part 12 is controlled to move away from the reaction wall to realize the separation from the two; it saves time and effort, and has high power transmission efficiency.

[0049] See also Figure 1 , Figure 2 and Figure 4 The pushing device 1 also includes: a driving member 13 and a limit baffle 14, and the limit baffle 14 is arranged at the connection between the driving member 13 and the supporting part 12.

[0050] When the pushing device 1 is in a non-working state, the limit baffle 14 is in close contact with the rear wall of the loader 3;

[0051] When the pushing device 1 finishes its work and returns to its original position, the limit baffle 14 plays a limiting role to prevent the pushing device 1 from retracting excessively. That is, the pushing device 1 can move forward and backward on the loader 3 in a limited forward and backward movement.

[0052] See also Figure 1 and Figure 2 A pushing trolley also includes a frame 4, a loader 3 is fixedly arranged on a vehicle body 5, the loader 3 is provided with a shell 31, the shell 31 and the frame 4 are both fixed on the vehicle body 5, and the frame 4 is arranged on the left and right sides of the loader 3, and the two sides are the two sides without the pushing device 1. Specifically, the frame 4 is arranged as a straight ladder, so that the staff can climb to the top of the loader 3.

[0053] See also Figure 2 , Figure 3 and Figure 5 Four mounting holes 311 are respectively opened on the front wall and the rear wall of the loader housing 31 , and the four driving members 13 are respectively inserted into the mounting holes 311 .

[0054] Specifically, the arrangement of the pushing devices 1 is not limited to four, and one or more driving members 13 may be arranged to provide a pushing force for the conductive pushing plate 2 .

[0055] In the present application, the pushing device 1 is arranged on the loader 3 so as to be movable forward and backward, and the driving member 13 is controlled to move relative to the loader 3, so as to realize the switching of the furnace tail pushing trolley between the power transmission state and the non-power transmission state. Specifically, in the power transmission state, the trolley controls the pushing part 11 of the pushing device 1 to move toward the conductive electrode of the graphitization furnace. In the process of the conductive push plate 2 pushing the conductive electrode, under the influence of the reaction force, the driving member 13 that can move forward and backward inside the loader 3 will be moved backward under the action of the reaction force, and at the same time, the driving member 13 controls the support part 12 to move toward the reaction wall to realize the support of the conductive push plate 2; in the non-power transmission state, the pushing part 11 of the driving member 13 is controlled to move away from the conductive electrode of the graphitization furnace, and the support part 12 is controlled to move away from the reaction wall to realize the separation from the two; the switching between the power transmission state and the non-power transmission state only uses the power of the pushing device 1 itself, without manual participation, saving time and effort, and high power transmission efficiency.

[0056] Exemplarily, the bidirectional telescopic method of the jacking device 1 is composed of two automatically adjustable components, such as two one-way cylinders, or a double-extension cylinder that can perform bidirectional telescopic operation; this can reduce the use of manpower.

[0057] For example, during the pushing process, affected by the reaction force, the pushing device 1 will move toward the reaction wall inside the loader 3. Therefore, the support part 12 of the pushing device 1 no longer needs to be provided with a retractable cylinder for adjustment. It is only necessary to use an ordinary one-way cylinder in the pushing part 11 of the pushing device 1, which can effectively save materials.

[0058] A positioning retaining ring 33 is detachably provided on the front wall and the rear wall of the shell 31 of the loader 3 . The positioning retaining ring 33 and the front wall of the shell 31 or the rear wall of the shell 31 together form a mounting hole 311 .

[0059] During assembly, the assembler first fixes the push device 1 to the housing 31 of the loader 3, and then installs the positioning retaining ring 33 on the housing 31, thereby fixing the push device 1 to the mounting hole 311. That is, the push device 1 is pre-installed first, and then the push device 1 is fixed, which greatly reduces the difficulty of assembly and improves the assembly efficiency.

[0060] A reinforcing rib 35 is provided on the inner wall of the housing 31 of the loader 3 and is located between the upper and lower groups of the pushing devices 1 without directly contacting the pushing devices 1 .

[0061] For example, the reinforcing ribs 35 mainly support the shell 31 and can overcome the local load on the shell 31 caused by the activity of the driving member 13, thereby increasing the mechanical strength. Specifically, the reinforcing ribs can be placed on the upper and lower sides of the driving member 13, or the reinforcing ribs 35 on both sides can be connected together.

[0062] In some specific embodiments, the bottoms of both sides of the shell 31 of the loader 3 are not completely closed to form wire threading grooves 34, and the wire threading grooves 34 are used for connecting parts such as wires and cables to pass through.

[0063] See also Figure 1 , Figure 2 and Figure 4 The pushing portion 11 and the supporting portion 12 are respectively arranged at two ends of the driving member 13 .

[0064] Among them, the pushing part 11 includes: a pushing shaft 111 and a pushing plate 112; the supporting part 12 includes: a supporting shaft 121 and a supporting plate 122; the pushing plate 112 is fixedly connected to the outward end of the pushing shaft 111, and the supporting plate 122 is fixedly connected to the outward end of the supporting shaft 121, and the pushing shaft 111 and the supporting shaft 121 are both flexibly connected to the driving member 13.

[0065] In this way, the push shaft 111 and the support shaft 121 belong to the same driving device and can perform telescopic movements independently.

[0066] If a bidirectionally retractable push device 1 is used, then: when the power transmission trolley is about to start transmitting power, the support shaft 121 is activated first, the support shaft 121 is extended to a certain position, and the object can be supported behind it. Then, the push shaft 111 is activated, and the push shaft 111 is extended, driving the conductive push plate 2 to move toward the electrode until it is in full contact with the electrode;

[0067] When the power transmission trolley finishes transmitting power, the push shaft 111 is activated first, and the push shaft 111 is retracted to the driving member 13 to end the power transmission. Subsequently, the support shaft 121 is activated, and the support shaft 121 is retracted to the driving member 13.

[0068] If a unidirectional telescopic push device 1 is used, then: when the power transmission trolley is about to start power transmission, the push shaft 111 is activated first, the push shaft 111 extends, and drives the conductive push plate 2 to move toward the electrode. When it is in full contact with the electrode, it continues to push toward the electrode. At this time, the driving member 13 and the support part 12 move toward the reaction wall as a whole until they abut against the rear reaction wall.

[0069] When the power transmission trolley finishes power transmission, the push shaft 111 is activated first, and the push shaft 111 is retracted to the driving member 13 to end power transmission, and then the support part 12 is retracted to the original position.

[0070] Exemplarily, the pushing plate 112 and the supporting plate 122 of the pushing device 1 are both block-shaped structures, such as square plate-shaped or circular plate-shaped;

[0071] Exemplarily, the movement of the support shaft 121 is a flexible movement, such as axial expansion and contraction, or helical expansion and contraction along a thread.

[0072] See also Figure 1 , Figure 2 and Figure 3 , wherein the frame 4 further includes: a walking plate 41 and a guardrail 42;

[0073] A walkway 41 is provided at the top of the frame 4, mainly for workers to stand and observe the power transmission situation;

[0074] The guardrail 42 is arranged on both sides of the walkway 33 along the direction of the pushing device 1 and is perpendicular to the pushing device 1. The bottom of the guardrail 42 is fixedly connected to the frame 4 to protect the safety of the staff.

[0075] See also Figures 1 to 4 The conductive push plate 2 includes: a first push plate portion 21, a second push plate portion 22 and a soft connection portion 23;

[0076] The first push plate portion 21 and the second push plate portion 22 are respectively located on both sides of the soft connection portion 23, and the middle of the soft connection portion is made of flexible material, so as to avoid the conductive push plate 2 from being damaged during the movement;

[0077] The first push plate portion 21 is fixedly connected to the four push devices 1 through four push plates 112, and the second push plate portion 22 is fixedly connected to the four push devices 1 through four push plates 112. Each push plate portion is provided with a loader 3 and a plurality of push devices 1 to provide a push force for the push plate portion.

[0078] Exemplarily, the conductive push plate 2 is in direct contact with the conductive electrode, and each conductive push plate 2 has the effect of providing power to the electrode, so it can be disassembled into two separate conductive push plates 2;

[0079] Specifically, two or more conductive push plates 2 may be provided to be in synchronous contact with a plurality of conductive electrodes by being connected to each other.

[0080] The conductive push plate 2 further includes a wheel set 24, which is disposed at the bottom of the first push plate portion 21 and the second push plate portion 22. Each copper plate portion is provided with two sets of wheel sets 24, which are respectively located at the two ends of the bottom of the conductive push plate 2;

[0081] The wheel set 24 can not only make the conductive push plate 2 move more smoothly, but also prevent the conductive push plate 2 from breaking at the connection between the conductive push plate 2 and the jacking device 1 due to the excessive weight of the copper bar during the movement, thus playing a certain supporting role.

[0082] Exemplarily, the wheel set 24 provides movement and support for the conductive push plate 2 . Other implementation methods may include using rollers or track wheels.

[0083] It should be noted that the friction force between the pushing device 1 and the loader 3 is configured to be smaller than the friction force between the wheel group 24 and the vehicle body 5. In this way, during the reverse pushing process of the conductive electrode, the pushing device 1 can be prevented from driving the conductive push plate 2 to move by itself, so that the switching between the power transmission state and the non-power transmission state can be achieved by only using the power of the pushing device 1 itself, without manual participation, saving time and effort, and having high power transmission efficiency.

[0084] 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.
