Description

Technical Field

[0001] The utility model belongs to the technical field of graphitization furnaces, and particularly relates to an electric connection clamping mechanism. Background Art

[0002] With the development of economy and the continuous changes in energy structure, AC graphitization furnaces are used more and more in industrial production. The conductive trolley is one of the important equipment necessary in its production process. The convenience and reliability of the conductive trolley 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] like Figure 4 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 4 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, and the existing power connection clamping mechanism does not have the ability of self-adjustment, which leads to the loose fit between the clamping plate and the busbar power connection part a and the graphitization furnace power connection part b, thereby increasing the resistance at the joint, increasing the heat generation, reducing the conductivity efficiency, affecting the energy utilization efficiency, and also applying a bias load to the busbar power connection part a and / or the graphitization furnace power connection part b, causing their damage.

[0005] The utility model provides a power connection clamping mechanism, which has a self-adjusting function, and can make the power connection assembly fit tightly with the busbar power connection part and the graphitization furnace power connection part. The technical solution is as follows:

[0006] A power connection clamping mechanism comprises an upper platform, a power connection assembly and a driving mechanism; the driving mechanism comprises a support seat, a cylinder and a supporting trolley, the support seat is fixedly mounted on the upper platform, the cylinder is mounted on the support seat, a vehicle track is provided on the upper platform, the supporting trolley can slide along the vehicle track, the power connection assembly is arranged on the supporting trolley, and the driving end of the cylinder is connected to the power connection assembly; the power connection assembly comprises a first clamping plate, a flexible connecting portion and a second clamping plate, the power connection assemblies are two and are arranged in a mirror-symmetrical manner; the flexible connecting portion is made of a conductive material and electrically connects the first clamping plate with the second clamping plate.

[0007] Based on the above technical solution, the power connection assembly also includes a cooling water tank, and the cooling water tank is arranged on the back of the first clamping plate and the second clamping plate.

[0011] Beneficial Effects

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1.

The connection between the driving end of the oil cylinder and the ball head of the power connection assembly also enables or further enables the power connection assembly to better fit with the busbar power connection part and the graphitization furnace power connection part. 3.

[0024] See also Figure 1 and Figure 3, a power connection clamping mechanism, including an upper platform 4, a power connection assembly 5 and a driving mechanism; the driving mechanism includes a support seat 51, a cylinder 52 and a supporting trolley 56, the support seat 51 is fixedly installed on the upper platform 4, the cylinder 52 is installed on the support seat 51, the power connection assembly 5 is arranged on the supporting trolley 56, and the driving end of the cylinder 52 is connected to the power connection assembly 5; the power connection assembly 5 includes a first clamping plate 541, a flexible connecting portion 542 and a second clamping plate 543, and the power connection assembly 5 is two and is arranged in a mirror-symmetrical manner; 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.

[0025] As an implementation manner, the power connection assembly 5 further includes a cooling water tank 55 , and the cooling water tank 55 is disposed on the back of the first clamping plate 541 and the second clamping plate 543 .

[0026] Preferably, the driving end of the oil cylinder 52 is connected to the ball head of the power connection assembly 5.

[0027] like Figure 5 As shown, the cooling water tank 55 has a water inlet and a water outlet, and has a plurality of staggered partitions 551 inside.

[0028] like Figure 4 As shown in the figure, the design requires that the plane where the busbar connection part a is located coincides with the plane where the graphitization furnace connection part b is located. However, in the 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 (with a displacement of 1.000 mm / s). Figure 4 For reference, it is reflected that one 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, and the connecting part 542 is made of a copper hose. It has a certain deformability. In this way, 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.

[0029] The power connection assembly 5 has the ability to universally rotate relative to the driving end of the 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, thereby improving energy utilization efficiency and avoiding applying eccentric loads to the busbar power connection part a and / or the graphitization furnace power connection part b, avoiding their damage and increasing their service life.

[0030] Optionally, a track 42 is provided on the upper platform 4 , and the supporting trolley 56 can slide along the track 42 .

[0031] Since the 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, which is also heavier. The setting of the support trolley can provide good support for the power connection assembly 5 and facilitate its movement.

[0032] Use, such as Figure 2 As shown, the power connection clamping mechanism is installed on the conductive vehicle body 1, and a driving device 2 for driving the conductive vehicle body 1 to start and stop is provided on the conductive vehicle body 1.

[0033] The conductive vehicle body 1 is driven to the position where the graphitization furnace needs to be connected to electricity, and the power connection assembly 5 arranged in a mirror-symmetrical manner clamps the busbar power connection part a and the graphitization furnace power connection part b.

[0034] The electrical connection assembly 5 will generate heat during the conduction process, and the provided cooling water tank 55 can effectively cool the electrical connection assembly 5 .

[0035] 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.
