Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0029] The graphitization furnace is a device that uses graphite as fuel and generates high temperature through heating to cause the graphitization of carbon materials. The push trolley is a movable device in the working system of the graphitization furnace. The push trolley can be divided into: power supply trolley and furnace loading trolley. The power supply trolley mainly supplies power to the graphitization furnace, and the furnace loading trolley mainly loads materials in the graphitization furnace. In the working state of the graphitization furnace, the push trolley moves between the graphitization furnace and the counterforce wall according to the pre-set guide rail between the graphitization furnace and the counterforce wall to the corresponding graphitization furnace position for power supply or furnace loading.

[0030] In the related art, a plurality of drive elements are arranged on the trolley body of the push trolley, and the push trolley is driven to move on the guide rail by the plurality of drive elements to realize power supply or furnace loading of the push trolley.

[0031] However, in actual work, although the arrangement of a plurality of drive motors can provide greater traction for the power supply trolley, it also makes the trolley body structure more complex and increases the use cost. Therefore, a single drive motor is used to pull the trolley body in a scene with low traction demand. However, in actual work, it is difficult to assemble a single motor on the trolley body.

[0032] Please refer to Figure 1 and Figure 2The application provides a pushing trolley to solve the problem of large assembly difficulty of the single motor.

[0033] A pushing trolley comprises:

[0034] A pushing mechanism 1;

[0035] A trolley body 2, wherein the pushing mechanism 1 is arranged on the trolley body 2, and the trolley body 2 is provided with a wheel set 21;

[0036] A power assembly 3, wherein the power assembly 3 is arranged on the trolley body 2 and connected with the wheel set 21 to provide power for the wheel set 21;

[0037] The power assembly 3 comprises a driving member 31, a bearing 32, a universal coupling 34 and a coupling flange 33, the bearing 32 is arranged in the wheel set 21, one end of the driving member 31 is connected with the bearing 32, and the other end is connected with the coupling flange 33, and the universal coupling 34 is movably connected with the coupling flange 33 at both ends.

[0038] In the utility model, the universal coupling 34 is arranged in the power assembly 3, the driving member 31 is arranged on the coupling flange 33, and the universal coupling 34 is movably connected with the coupling flange 33, so that the coaxiality of the driving member 31 and the wheel set 21 can be reduced when the wheel set 34 is not coaxial, and the installation difficulty of the driving member 31 is reduced.

[0039] Please refer to Figure 1 and Figure 2 In the pushing trolley provided by the application, the wheel set 21 comprises a first driving wheel 211, a second driving wheel 212 and two driven wheels, and the first driving wheel 211, the second driving wheel 212 and the two driven wheels are all arranged on the bottom of the trolley body 2.

[0040] The first driving wheel 211 and the second driving wheel 212 are oppositely arranged, and the driving member 31 is arranged close to the second driving wheel 212.

[0041] The first driving wheel 211 and the second driving wheel 212 are connected, and the driving member 31 is arranged close to the second driving wheel 212 and deviated from the center, that is, the installation difficulty of the driving member 31 and the second driving wheel 212 is reduced, and the universal coupling 34 is not arranged between the driving member 31 and the second driving wheel 212, so that the pushing trolley can drive the two driving wheels on the two sides to move by using only one driving member 31 between the driving member 31 and the first driving wheel 211, and only one universal coupling 34 is used, so that the installation difficulty and the equipment cost are reduced.

[0042] In alternative embodiments, the specific positions of the driving wheel and the driven wheel can be moved according to actual working scenes, the driven wheel can be provided with two or more, and the driving member 31 can be installed near the first driving wheel 211.

[0043] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the bearing 32 includes a first bearing 321 and a second bearing 322, and the shaft coupling flange 33 includes a first shaft coupling flange 331 and a second shaft coupling flange 332.

[0044] The outer end of the first bearing 321 is arranged inside the first driving wheel 211, and the inner end is sleeved in the first shaft coupling flange 331. The other end of the first shaft coupling flange 331 is attached to one end of the universal coupling 34, the other end of the second shaft coupling flange 332 is attached to the other end of the universal coupling 34, the second shaft coupling flange 332 is connected with the driving member 31, and the inner end of the second bearing 322 penetrates through the driving member 31 and is sleeved in the second shaft coupling flange 332. The other end of the second bearing 322 is installed in the second driving wheel 212.

[0045] Among them, the shaft coupling flange 33 is T-shaped and horizontally arranged between the bearing 32 and the universal coupling 34. The T-shaped tail of the shaft coupling flange 33 is sleeved with the bearing 32, and the top is attached with the universal coupling 34.

[0046] The power assembly 3 formed by the driving member 31, the bearing 32, the shaft coupling flange 33 and the universal coupling 34 simplifies the structure of the single driving member 31, reduces the coaxiality of the driving member 31 and the remaining connected parts, and further reduces the installation difficulty of the driving member.

[0047] Please refer to Figure 3 and Figure 4 In this embodiment, the universal coupling 34 includes a U-shaped bolt 341, a cross shaft 342, and a coupling body 343.

[0048] Among them, the U-shaped bolt includes a first U-shaped bolt 3411, a second U-shaped bolt 3412, a third U-shaped bolt 3413 and a fourth U-shaped bolt 3414, and the cross shaft 342 includes a first cross shaft 3421 and a second cross shaft 3422.

[0049] The first U-shaped bolt 3411 and the second U-shaped bolt 3412 are arranged at 90°, and the horizontal axis and the vertical axis of the first cross shaft 3421 are respectively inserted into the first U-shaped bolt 3411 and the second U-shaped bolt 3412. Similarly, the third U-shaped bolt 3413 and the fourth U-shaped bolt 3414 are arranged at 90°, and the horizontal axis and the vertical axis of the second cross shaft 3422 are respectively inserted into the third U-shaped bolt 3413 and the fourth U-shaped bolt 3414.

[0050] The second U-shaped pin 3412 and the third U-shaped pin 3413 are respectively fixed at two ends of the coupling body 343.

[0051] The single cross universal coupling is used only to reduce the installation difficulty of the single driving member 31, and the cross shaft type is used because the cross universal coupling has the advantages of strong angle compensation ability, reliable torque transmission and low maintenance cost.

[0052] In alternative embodiments, the cross shaft 342 can be replaced by a ball cage type or ball fork type universal coupling, which can also play a role in shock absorption and transmission efficiency improvement.

[0053] The coupling body 2332 is slightly deformed during the offset of the cross shaft, and will not be broken due to the offset of the cross shaft 2331.

[0054] It can be known that the movable shaft angle of the universal coupling 233 is between 5° and 45°.

[0055] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom still belong to the protection scope of the present application.
