Description
Technical Field
[0001] The utility model belongs to the technical field of graphitization furnaces, and in particular relates to a shear-type conductive vehicle. Background Art
[0002] With the development of economy and the continuous change of energy structure, AC graphitization furnace is used more and more in industrial production. Conductive car is one of the important equipments in its production process. The convenience and reliability of conductive car is particularly important in production.
[0003] The AC graphitization furnace is intermittently operated. In one production cycle, it has to go through the processes of loading, power supply, cooling, unloading, and maintenance, which takes a total of 12 to 15 days, and power supply only takes 3 to 5 days. Generally, one transformer can be equipped with 5 to 7 furnaces of the same specifications to form a furnace group, and one furnace group is a production unit. During production, the transformer runs continuously and the furnaces work in turn; usually one furnace in a furnace group is in the power-on state, and the other furnaces are in the states of loading, cooling, loading and unloading or maintenance; after one furnace is finished working, the next furnace is powered on. Generally, a track is laid in front of each furnace group, and the conductive car walks on the track. According to the needs, the furnace head electrode of the furnace to be put into operation is connected to the busbar. After the power-on heating is completed, the conductive car disconnects the furnace head electrode from the busbar, and then moves to the next furnace that needs to work to connect the furnace head electrode and the busbar.
[0004] The conventional conductive vehicle is composed of a traveling frame and an upper platform, which is connected to the frame by a set of (four) oil cylinders. The upper platform is ensured to be lifted and lowered smoothly by controlling the synchronization of the oil cylinders. In addition, two sets of clamping mechanisms are installed on the upper platform, so that two furnace heads can be connected to conduct electricity at the same time. However, this makes the conductive vehicle structure more complicated and the vehicle body larger. The disadvantages of the prior art shown in FIG1 are as follows: 1. Due to the large body and long length, it is difficult to achieve stable hydraulic synchronous lifting. As the lifting height increases, the stability will become worse and worse.
[0005] 2: If the conductive vehicle is to connect two burners for conduction at the same time, this requires a high accuracy of the electrode position of the two burners, and the on-site construction is relatively difficult. If the electrode position accuracy does not meet the requirements, two situations will occur: either give up connecting the two burners for conduction at the same time and only connect one burner; or forcibly connect the two burners, which will impose a bias load on the burner electrode plate, causing the burner electrode plate to break.
[0006] 3: The huge conductive vehicle runs on the track, which takes up a large space, is not flexible in operation, has high cost and low cost performance.

[0032] See also Figure 2 , Figure 3 and Figure 6As shown, a shear-type conductive vehicle of the utility model comprises a traveling frame 1, a first driving mechanism for driving the traveling frame 1 to travel, an upper platform 4, a lifting mechanism for driving the upper platform 4 to rise and fall relative to the traveling frame 1, a power connection assembly 5 for connecting the busbar power connection part a and the graphitization furnace power connection part b and making them electrically conductive, and a second driving mechanism for driving the power connection assembly 5 to contact or separate from the busbar power connection part and the graphitization furnace power connection part; the power connection assembly 5 and the second driving mechanism are installed on the upper platform 4, and the lifting mechanism comprises a first oil cylinder 37 and a shear-type Fork frame 3; the shear-type fork frame 3 includes an inner fork frame 31 and an outer fork frame 32, the inner fork frame 31 and the outer fork frame 32 are hinged to form an X shape, the top of the inner fork frame 31 is hinged to the traveling frame 1, and the bottom is hinged to the upper slider 36-1; the upper slider 36-1 is slidably connected to the upper platform 4, the top of the outer fork frame 32 is hinged to the upper platform 4, and the bottom is hinged to the lower slider 36-2; the lower slider 36-2 is slidably connected to the traveling frame 1, one end of the first oil cylinder 37 is hinged to the inner fork frame 31, and the other end is hinged to the outer fork frame 32. The relationship between the first oil cylinder 37 and the outer fork frame and the inner fork frame can be adopted but not limited to the following methods: Figure 3 As shown, the cylinder body of the first oil cylinder 37 is hinged to the outer fork frame 32, and the piston rod thereof is hinged to the inner fork frame 31, thereby driving the inner fork frame 31 and the outer fork frame 32 to rotate relative to each other. The number of the first oil cylinder 37 is at least one, for example, four. Figure 5 As shown, the power connection assembly 5 includes a first clamping plate 541, a flexible connecting portion 542 and a second clamping plate 543. The power connection assembly 5 is two and is arranged symmetrically in a mirror direction. The flexible connecting portion 542 is made of a conductive material and electrically connects the first clamping plate 541 with the second clamping plate 543.
[0033] Among them, the connecting part 542 can be made of a copper hose, which has a certain deformability. Therefore, when the positions of the busbar power connection part a and the graphitization furnace power connection part b are not accurate, such as not completely on the same plane, the connecting part can provide a certain amount of deformation, so that the first clamping plate 541 can better fit the busbar power connection part a, and the second clamping plate 543 can better fit the graphitization furnace power connection part b.
[0034] The power connection assembly 5 further includes a cooling water tank 55, which is disposed on the back of the first clamping plate 541 and the second clamping plate 543. The back refers to the side away from the clamping end when the power connection assembly 5 clamps the busbar power connection part a or the graphitization furnace power connection part b.
[0035] The first driving mechanism is a travel motor 2 arranged on a travel frame 1, a wheel 11 is installed at the bottom of the travel frame 1, and the travel motor 2 is connected to the wheel to drive the wheel 11 to start and stop. A track can be arranged in the operating area of the conductive vehicle, such as a tunnel, so that the conductive vehicle can travel along the track.
[0036] As an implementation method: Figure 4 As shown, the second driving mechanism includes a support seat 51, a second oil cylinder 52 and a support trolley 56. The support seat 51 is fixedly mounted on the upper platform 4, the second oil cylinder 52 is mounted on the support seat 51, the upper platform 4 is provided with a track 42, the support trolley 56 can slide along the track 42, the power connection assembly 5 is arranged on the support trolley 56, and the driving end of the second oil cylinder 52 is connected to the power connection assembly 5. Since the amount of current flowing through the power connection assembly 5 is particularly large, the power connection assembly 5 needs to be designed to be larger, and the material is mostly made of copper and the weight is also larger. The setting of the support trolley can provide good support for the power connection assembly 5 and facilitate its movement.
[0037] Preferably, the driving end of the second oil cylinder 52 is connected to the ball head of the power connection assembly 5. The power connection assembly 5 has the ability to rotate universally relative to the driving end of the second oil cylinder 52, so that the first clamping plate 541 can better fit the busbar power connection part a, and the second clamping plate 543 can better fit the graphitization furnace power connection part b.
[0038] like Figure 6 As shown in FIG. 1 , the busbar connection part a and the graphitization furnace connection part b are generally plate-shaped. In an actual working environment, the busbar connection part a and the graphitization furnace connection part b are often not completely on the same plane due to errors during construction or after a period of use. For example, the busbar connection part a is offset horizontally relative to the graphitization furnace connection part b (in Figure 6 For reference, it is reflected in that one of them is in front of the other, that is, the end faces of the two facing the observer do not overlap) and / or the busbar power connection part a has a small torsion angle relative to the graphitization furnace power connection part b. In this case, if there is no flexible connection part 542 and / or the driving end of the second oil cylinder 52 is connected to the ball head of the power connection assembly 5, it will cause the power connection assembly 5 to be loosely fitted with the busbar power connection part a and the graphitization furnace power connection part b, resulting in increased resistance at the fitting point, increased heat generation, reduced conductivity efficiency, and affected energy utilization efficiency. At the same time, it will also apply a bias load to the busbar power connection part a and / or the graphitization furnace power connection part b, causing them to be damaged.
[0039] As an implementation method: the lower slider 36-2 is hinged with a ratchet 35-1, and the traveling frame 1 is provided with a safety rack 35-2. When the lifting mechanism is required to perform an ascending action, Figure 3 As shown, the ratchet 35-1 is rotated counterclockwise, so that the upper platform 4 can be raised without obstruction and the upper platform 4 can be prevented from falling suddenly due to failure of the first oil cylinder. When the lifting mechanism needs to descend, Figure 3 For reference, the ratchet 35 - 1 is rotated clockwise to the other side, so that the upper platform 4 can be unhindered when descending.
[0040] The wheels 11 are made of insulating material, such as nylon. The wheels supporting the trolley 56 are made of insulating material, such as nylon.
[0041] Optionally, a guardrail 41 is provided around the upper platform 4 .
[0042] When the graphitization furnace needs to be powered, the travel motor 2 drives the conductive vehicle to the corresponding position and raises the shear fork frame 3 to the corresponding height. The second drive mechanism causes the first clamping plate 541 and the second clamping plate 543 to clamp the busbar power connection part a and the graphitization furnace power connection part b respectively, and the busbar power connection part a and the graphitization furnace power connection part b are connected to supply power. After the power supply is completed, the power connection assembly releases the busbar power connection part a and the graphitization furnace power connection part b, the shear fork frame 3 descends, and the travel motor 2 drives the conductive vehicle to the next working position for power supply.
[0043] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
