Description

Technical Field

[0001] The invention relates to the technical field of power supply equipment for a graphitization furnace, and in particular to a push trolley. Background Art

[0002] The push trolley is a movable device that provides electric energy for 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 transmitting power to the in-line 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 provided on the power transmission busbar extending downward. The push mechanism of the power transmission vehicle includes: a frame, two push plates provided on both sides of the frame, and two soft copper belts connecting the push plates on both sides. The power transmission busbar transmits current to the soft copper belt by contacting the push plate on one side, and then transmits current to the push plate on the other side through the soft copper belt to supply power to the conductive electrode. Support members are provided on both sides of the frame to reinforce the frame. When the non-working state is switched to the working state, the two push plates move toward the branch busbar of the power transmission busbar and the conductive electrode of the graphitization furnace respectively, and at the same time drive the soft copper belts on both sides to extend until the two push plates respectively abut the conductive electrode and the branch busbar. When the working state is switched to the non-working state, the two push plates are separated from the conductive electrode and the branch busbar respectively, and the two push plates drive the soft copper belts on both sides to retract.

[0004] However, during the extension and retraction process of the soft copper belts on both sides, they are prone to contact and collide with the support parts of the frame, thereby affecting the service life of the support parts and the soft copper belts and the maintenance cost of the push trolley.

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention 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.

[0032] See also Figure 1 The present application provides a push trolley for supplying electricity to an inner string graphitization furnace.

[0033] In the scenario of supplying power to the inward string graphitization furnace, reaction walls are provided on the furnace head and furnace tail sides of the graphitization furnace, a power transmission busbar is provided on the reaction wall, and a branch busbar is provided downwardly extending from the power transmission busbar.

[0034] Specifically, the pushing trolley includes: a frame 2, two pushing plates 3 arranged on both sides of the frame 2, and a soft copper belt 1 connecting the two ends of the pushing plates 3 on both sides. The power transmission bus transmits current to the soft copper belt 1 by contacting the pushing plate 3 on one side, and then transmits current to the pushing plate 3 on the other side through the soft copper belt 1 to supply power to the conductive electrode. Support members 21 are provided on both sides of the frame 2 to reinforce the frame 2.

[0035] See also Figure 1 and Figure 2 One specific implementation of the present application provides a push trolley to solve the above-mentioned problem of high maintenance cost.

[0036] Specifically, a pushing trolley includes: a pushing mechanism, a soft copper belt 1 and a frame 2, the pushing mechanism has a driving cylinder, and two pushing plates 3 are respectively provided at both ends of the driving cylinder; the soft copper belt 1 connects the two pushing plates 3 of the pushing mechanism; the frame 2 is provided with at least two support members 21, and the support members 21 can be movably arranged on the outside of the soft copper belt 1.

[0037] In the present invention, the pushing mechanism is arranged on the vehicle body 4. The pushing mechanism is provided with a movable support member 21. By adjusting the position of the support member 21 in advance and fixing it at a certain position, the position needs to be able to ensure that the soft copper belt 1 will not contact the support member 21 during the deformation process, so that the soft copper belt 1 will not contact the support member 21 during the extension and retraction process, avoiding the interference of the support member 21 with the retraction process of the soft copper belt 1, increasing the service life of the soft copper belt 1 and the support member 21, and reducing the maintenance cost of the trolley.

[0038] In this embodiment, the push trolley is used as a movable device for providing electric energy 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.

[0039] When the non-working state is switched to the working state, the two push plates 3 move toward the branch busbar of the power transmission busbar and the conductive electrode of the graphitization furnace respectively, and at the same time drive the soft copper belts 1 on both sides to extend until the two push plates 3 respectively abut against the conductive electrode and the branch busbar. When the working state is switched to the non-working state, the two push plates 3 are separated from the conductive electrode and the branch busbar respectively, and the two push plates 3 drive the soft copper belts 1 on both sides thereof to retract.

[0040] See also Figure 1 , Figure 2 and Figure 3 The frame 2 is fixedly composed of a plurality of cross beams and longitudinal beams, and the frame 2 is also provided with a connecting beam 22.

[0041] In this embodiment, two connecting beams 22 are provided on one side of the pushing mechanism. The two connecting beams 22 are respectively located at the top and bottom ends of the frame 2 , wherein the two connecting beams 22 are movably connected by a support member 21 .

[0042] The connecting beam 22 at the upper end is fixed to the upper end of the frame 2 . The connecting beam 22 is a block structure, and a first transverse strip hole 221 is provided in the middle thereof, through which the supporting member 21 can move transversely.

[0043] The connecting beam 22 at the bottom is formed by folding a rectangular plate, which is folded once 90° toward the frame 2. The folded portion is fixedly connected to the vehicle body 4, and a first transverse strip hole 221 is provided in the middle thereof for the support member 21 to move transversely therein.

[0044] By providing the first strip holes 221 in the upper and lower connecting beams 22 , the support member 21 can move laterally therein to avoid collision with the soft copper strip 1 .

[0045] In an alternative embodiment, there are multiple options for connecting the connecting beam 22, such as setting the connecting beam 22 as a solid rod, and using a fully wrapped rectangular frame on the outside of the solid rod, so that the support member 21 connected to the outside of the rectangular frame can move with the movement of the rectangular frame.

[0046] Meanwhile, the specific shape of the connecting beam 22 is not limited thereto, and the folding direction and number of times can be determined according to actual production conditions.

[0047] See also Figure 3 , Figure 4 and Figure 5 The support member 21 includes: a mounting seat 211, a support tube 212, a positioning plate 213 and a support rod 214, the support rod 214 is fixed on the support tube 212, the mounting seat 211 is movably mounted on the connecting beam 22, the support tube 212 is fixed to the positioning plate 213, and is located on the mounting seat 211.

[0048] In a specific embodiment, two ends of the support rod 214 are fixed in mounting seats 211 that are oppositely arranged at upper and lower ends, and the mounting seats 211 move laterally in the first strip-shaped hole 221 of the connecting beam 22 .

[0049] Since the support rod 214 is a prior art, it will not be described in detail here.

[0050] See also Figure 3 , Figure 4 and Figure 5 The positioning plate 213 is movably disposed on the mounting seat 211 .

[0051] In one specific embodiment, since the mounting seats 211 and the connecting beam 22 at the upper and lower ends are arranged opposite to each other, the mounting seat 211 at the lower end is taken as an example.

[0052] The mounting seat 211 is made up of four block plates, one of which is the mounting plate 2111. The largest surface of the mounting plate 2111 matches the position of the first strip hole 221 of the connecting beam 22. The other three block plates are fixed on the opposite side of the largest surface of the mounting plate 2111. Positioning holes are provided on the left and right sides of the surface where the mounting plate 2111 matches the connecting beam 22, and it is fixed in a suitable position by installing positioning nuts (not shown in the figure).

[0053] The other three block plates of the mounting seat 211 are: a top plate 2112 and two support plates 2113. The two support plates 2113 are arranged side by side under the top plate 2112 to support the top plate 2112. The top plate 2112 of the mounting seat 211 is used to carry the positioning plate 213 and the support tube 212. The left and right ends of the top surface of the top plate 2112 are provided with second strip holes 2114.

[0054] The positioning plate 213 is horizontally arranged on the mounting seat 211. Positioning holes are provided at both ends of the top surface of the positioning plate 213. The positions of the positioning holes correspond to the second strip holes 2114 of the top plate 2112 of the mounting seat 211. It is fixed in a suitable position by installing positioning nuts (not shown in the figure).

[0055] The support tube 212 is fixed at the center position of the positioning plate 213. The support tube 212 includes: a circular tube 2121, a fixing ring 2122 and a rib plate 2123. The support rod 214 is inserted into the circular tube 2121 and fixed by the fixing ring 2122 at the mouth of the circular tube 2121. Four equidistant rib plates 2123 are provided on the outer wall of the circular tube 2121 to support the fixing ring 2122.

[0056] The overall position of the support member 21 can be adjusted by a primary movement of the positioning plate 213 and the mounting seat 211 and a secondary movement of the mounting seat 211 and the connecting beam 22, so that the support member 21 will not contact the soft copper strip 1 while ensuring its supporting effect.

[0057] See also Figure 1 and Figure 2 The frame 2 also includes a cylinder support frame 23, the support members 21 are located on both sides of the cylinder support frame 23, the driving cylinder is installed in the cylinder support frame 23, and the cylinder support frame 23 is fixed on the vehicle body 4.
