Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrodes, in particular to a graphitization furnace-out fixture for graphite electrodes. Background Art

[0002] Graphite electrode refers to a high-temperature resistant graphite conductive material made from petroleum coke and asphalt coke as aggregates and coal tar as binder, through the process of raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing.

[0003] After graphitization, the graphite electrode needs to be taken out with a clamp. The patent announcement number: CN220300170U proposes a graphite electrode graphitization furnace fixture, which mainly includes a support component and a clamp component. It has the advantages that the center of the graphite electrode is stable during the furnace lifting process and is not easy to fall or slip.

[0004] However, the existing clamps often need to operate at high temperatures during use. If the heat is not dissipated in time at high temperatures, the performance of the clamps may be degraded, the safety of the clamps during operation may be reduced, and the service life of the clamps may be affected. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide a graphite electrode graphitization furnace fixture to solve the problem that the existing fixture often needs to operate at high temperatures during use. If the heat is not dissipated in time at high temperatures, it is easy to cause the performance of the fixture to decline, which is easy to reduce the safety of the fixture during operation and also affect the service life of the fixture.

[0006] To achieve the above objectives, the utility model adopts the following technical solution: a graphite electrode graphitization furnace fixture, comprising a connecting box and a connecting rod, a telescopic hydraulic cylinder is installed inside the connecting box, and a reset spring is sleeved on the lower half of the telescopic hydraulic cylinder, a horizontal cross bar is connected to the lower part of the telescopic hydraulic cylinder, the connecting rod is installed on both sides of the connecting box through a rotating shaft, and a pin screw is installed at the end of the connecting rod away from the connecting box, an L-shaped rod fixture is connected below the pin screw, and a rotating shaft is installed in the middle part of the L-shaped rod fixture, a limiting nut is installed at the front end of the pin screw, and a connecting ring is installed through the pin screw, a reset spring is welded to the middle part of the connecting ring, a friction bump is installed on the lower half of the L-shaped rod fixture, and a ventilation hole is opened in the lower half of the L-shaped rod fixture.

[0007] The beneficial effect of the utility model is that during the clamping process, the ventilation holes cooperate with the heat dissipation slots opened on the outside of the L-shaped rod clamp to increase the surface area of ​​the L-shaped rod clamp, thereby increasing the heat dissipation efficiency of the L-shaped rod clamp. This method can effectively ensure the heat dissipation efficiency of the clamp and the safety of the clamp during operation, thereby ensuring the service life of the clamp.

[0008] When the L-shaped rod clamp is opened and closed, the second reset spring cooperates with the pin screw and the limit nut to support and pull the connecting rod and the L-shaped rod clamp, so that the opening and closing of the L-shaped rod clamp is more stable, thereby facilitating the removal of the graphite electrode.

[0009] To facilitate the opening and closing of the L-bar clamp:

[0010] As a further improvement of the above technical solution: a lifting and mounting structure is formed between the horizontal cross bar and the connection box through a telescopic hydraulic cylinder.

[0011] The beneficial effect of this improvement is that the telescopic hydraulic cylinder pulls the horizontal cross bar to drive the shaft installed in the middle part of the L-shaped rod clamp to rise and fall. The L-shaped rod clamp cooperates with the connecting rod to open and close as the shaft rises and falls, thereby facilitating the L-shaped rod clamp to clamp the graphite electrode.

[0012] To make the horizontal bar rise and fall more smoothly:

[0013] As a further improvement of the above technical solution: the return spring 1 and the telescopic hydraulic cylinder are arranged with their axes coincident, and the upper and lower ends of the return spring 1 are respectively welded to the connecting box and the horizontal cross bar.

[0014] The beneficial effect of this improvement is that the return spring 1 can pull or support the horizontal cross bar when the horizontal cross bar is raised or lowered, so that the telescopic hydraulic cylinder can drive the horizontal cross bar to rise or fall more reliably and smoothly.

[0015] To facilitate the opening and closing of the L-bar clamp:

[0016] As a further improvement of the above technical solution: the second reset spring is symmetrically distributed on both sides of the connecting rod, and the second reset spring and the horizontal cross bar are arranged parallel to each other.

[0017] The beneficial effect of this improvement is that when the L-shaped rod clamp is opened and closed, the two parallel reset springs cooperate with the pin screw and the limit nut to support and pull the connecting rod and the L-shaped rod clamp, making the opening and closing of the L-shaped rod clamp more stable.

[0018] To facilitate the installation of the limit nut:

[0019] As a further improvement of the above technical solution: the limiting nut and the pin screw are threadedly connected, and the pin screw and the connection box are arranged parallel to each other.

[0020] The beneficial effect of this improvement is that the threaded connection can enable the limiting nut to cooperate with the pin screw to limit the position of the connecting ring and the second reset spring, thereby facilitating the installation of the second reset spring.

[0021] To facilitate heat dissipation of the L-bar clamp:

[0022] As a further improvement of the above technical solution: the ventilation holes are opened at equal intervals in the lower half of the L-shaped rod clamp.

[0023] As a further improvement of the above technical solution: one end of the rotating shaft installed in the middle part of the L-shaped rod clamp is welded to the horizontal cross bar, and the lower part of the L-shaped rod clamp is provided with heat dissipation slots at equal intervals.

[0024] The beneficial effect of this improvement is that when the L-shaped rod clamp is clamping the graphite electrode, the ventilation holes cooperate with the heat dissipation slots to dissipate heat from the L-shaped rod clamp, thereby ensuring the heat dissipation efficiency of the L-shaped rod clamp.

[0025] In order to facilitate the connection between the device and the lifting device:

[0026] As a further improvement of the above technical solution: hanging rings are symmetrically arranged above the connection box.

[0027] The beneficial effect of this improvement is that the symmetrically arranged hanging rings can be connected to the lifting device through two points, thereby ensuring the stability of the connection between the device and the lifting device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0035] like Figure 1-5As shown, a graphite electrode graphitization furnace fixture comprises a connecting box 1 and a connecting rod 2, wherein a telescopic hydraulic cylinder 11 is installed inside the connecting box 1, and a return spring 12 is sleeved on the lower half of the telescopic hydraulic cylinder 11, and a horizontal cross bar 13 is connected to the lower part of the telescopic hydraulic cylinder 11, and the connecting rod 2 is installed on both sides of the connecting box 1 through a rotating shaft, and a pin screw 27 is installed at one end of the connecting rod 2 away from the connecting box 1, an L-shaped rod clamp 21 is connected below the pin screw 27, and a rotating shaft is installed in the middle part of the L-shaped rod clamp 21, a limiting nut 22 is installed at the front end of the pin screw 27, and a connecting ring 23 is installed through the pin screw 27, and a return spring 24 is welded to the middle part of the connecting ring 23, so that The lower half of the L-shaped rod clamp 21 is installed with a friction protrusion 25, and the lower half of the L-shaped rod clamp 21 is provided with a ventilation hole 26. During the clamping process, the ventilation hole 26 cooperates with the heat dissipation slots provided on the outer side of the L-shaped rod clamp 21 to increase the surface area of ​​the L-shaped rod clamp 21, thereby increasing the heat dissipation efficiency of the L-shaped rod clamp 21. This method can effectively ensure the heat dissipation efficiency of the clamp and the safety of the clamp during operation, thereby ensuring the service life of the clamp. When the L-shaped rod clamp 21 is opened and closed, the reset spring 24 cooperates with the pin screw 27 and the limit nut 22 to support and pull the connecting rod 2 and the L-shaped rod clamp 21, so that the opening and closing of the L-shaped rod clamp 21 are more stable, thereby facilitating the removal of the graphite electrode. The horizontal cross bar 13 and The telescopic hydraulic cylinder 11 is used to form a lifting installation structure between the connection boxes 1. The telescopic hydraulic cylinder 11 pulls the horizontal cross bar 13 to drive the shaft installed in the middle part of the L-shaped rod clamp 21 to rise and fall. The L-shaped rod clamp 21 cooperates with the connecting rod 2 to realize the opening and closing action as the shaft rises and falls, thereby facilitating the L-shaped rod clamp 21 to clamp the graphite electrode. The reset spring 12 and the telescopic hydraulic cylinder 11 are arranged with the axis coincident, and the upper and lower ends of the reset spring 12 are respectively welded to the connection box 1 and the horizontal cross bar 13. The reset spring 12 can pull or support the horizontal cross bar 13 when the horizontal cross bar 13 is lifted and lowered, so that the telescopic hydraulic cylinder 11 drives the horizontal cross bar 13 to rise and fall more reliably and stably. The reset spring 24 is symmetrically distributed on the connection box 1. On both sides of the rod 2, the reset spring 24 and the horizontal cross bar 13 are arranged in parallel with each other. When the L-shaped rod clamp 21 is opened and closed, the parallel reset spring 24 cooperates with the pin screw 27 and the limit nut 22 to support and pull the connecting rod 2 and the L-shaped rod clamp 21, so that the opening and closing of the L-shaped rod clamp 21 are more stable. The limit nut 22 and the pin screw 27 are threadedly connected, and the pin screw 27 and the connection box 1 are arranged in parallel with each other. The threaded connection can make the limit nut 22 cooperate with the pin screw 27 to limit the position of the connecting ring 23 and the reset spring 24, thereby facilitating the installation of the reset spring 24. The ventilation holes 26 are evenly spaced and arranged in the lower half of the L-shaped rod clamp 21.One end of the rotating shaft installed in the middle of the L-shaped rod clamp 21 is welded to the horizontal cross bar 13, and the lower half of the L-shaped rod clamp 21 is provided with heat dissipation slots at equal intervals. When the L-shaped rod clamp 21 clamps the graphite electrode, the ventilation holes 26 cooperate with the heat dissipation slots to dissipate heat for the L-shaped rod clamp 21, thereby ensuring the heat dissipation efficiency of the L-shaped rod clamp 21. Hanging rings are symmetrically arranged above the connection box 1, and the symmetrically arranged hanging rings can be connected to the lifting device at two points to ensure the stability of the connection between the device and the lifting device.

[0036] The working principle of the utility model is as follows: when taking out the graphitized graphite electrode, hook the matching lifting device on the hanging ring, and then move the clamp to a suitable position in the graphitization furnace. At this time, the device lowers the L-shaped rod clamp 21 to reach the outside of the graphite electrode. At this time, the telescopic hydraulic cylinder 11 pulls the rotating shaft installed in the middle of the horizontal cross bar 13 and the L-shaped rod clamp 21 to descend. The L-shaped rod clamp 21 clamps the graphite electrode as the rotating shaft descends. After clamping, the lifting device moves the graphite electrode to the storage position. During the clamping process, the ventilation hole 26 cooperates with the The heat dissipation slots opened on the outside of the L-shaped rod clamp 21 increase the surface area of ​​the L-shaped rod clamp 21, thereby increasing the heat dissipation efficiency of the L-shaped rod clamp 21. This method can effectively ensure the heat dissipation efficiency of the clamp and the safety of the clamp during operation, thereby ensuring the service life of the clamp. When the L-shaped rod clamp 21 is opened and closed, the reset spring 24 cooperates with the pin screw 27 and the limit nut 22 to support and pull the connecting rod 2 and the L-shaped rod clamp 21, so that the opening and closing of the L-shaped rod clamp 21 are more stable, thereby facilitating the removal of the graphite electrode.
