Description

Technical Field

[0001] The utility model belongs to the field of graphite component disassembly and assembly, in particular to a graphite component installation and disassembly device. Background Art

[0002] A heat furnace is a device used to heat objects and is widely used in industry. Graphite parts (also called graphite blocks) are set inside to carry and conduct heat energy. The heat is transferred to the object through conduction and heat transfer of the graphite parts to increase the temperature of the object. Graphite parts need to be disassembled and replaced after long-term use.

[0003] When the graphite parts are disassembled and assembled in the heating furnace, the personnel manually take the graphite parts and then lift the graphite parts to separate the graphite parts from the heating furnace, thereby realizing disassembly. Conversely, the graphite parts are taken and placed in the heating furnace to realize assembly. However, in the prior art, when the graphite parts inside the heating furnace are disassembled and assembled, due to the large size of the heating furnace, the graphite parts are easily affected by the weight of the graphite parts when being taken manually, and they will be relatively unstable when being picked up, and they are easy to slip during the picking process, thereby increasing the inconvenience of disassembling and assembling the graphite parts.

[0004] In summary, the utility model provides a graphite component installation and disassembly device to solve the above problems. Utility Model Content

In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a graphite part installation and disassembly device, which is applied to a heating furnace body 1, the inner cavity of the heating furnace body 1 is movably connected with a central tube 2, the bottom of the central tube 2 is provided with a muffle tube 3, the surfaces of the central tube 2 and the muffle tube 3 are provided with a connecting unit 5, the inner cavities of the central tube 2 and the muffle tube 3 are provided with a light rod 6, the surface of the muffle tube 3 is provided with a card slot 4, the connecting unit 5 includes a card block 51, and the number of the card blocks 51 is two, the top of the card block 51 is provided with a steel wire rope 52, the side of the two card blocks 51 close to each other is fixedly connected with a connecting plate 53, and a tension spring 54 is fixedly connected between every two connecting plates 53, the top of the central tube 2 is movably connected with a fixing ring 55, and the other end of the steel wire rope 52 is provided with a connecting ring 521.

[0023] like Figure 1-4 As shown, the clamping block 51 is sleeved on the surface of the muffle tube 3, and the reset elastic force of the tension spring 54 drives the connecting plate 53 and the clamping block 51 to retract inward, so that the clamping block 51 enters the inner cavity of the clamping slot 4 to achieve clamping, and is connected to the top of the center tube 2 along the steel wire rope 52 through the fixing ring 55 to achieve limiting, thereby preventing instability during later extraction. The connecting ring 521 can be connected to the external feeding system, and then the connecting ring 521 can drive the steel wire rope 52, the clamping block 51, the center tube 2 and the muffle tube 3 to gradually separate from the inner cavity of the heating furnace body 1 upward, thereby facilitating the removal of the center tube 2 and the muffle tube 3. Conversely, the connecting ring 521 drives the steel wire rope 52, the clamping block 51, the center tube 2 and the muffle tube 3 downward into the interior of the heating furnace body 1 to achieve installation.

[0024] Example 2

[0025] Reference Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the number of the steel wire ropes 52 is four and they are evenly distributed on both sides of the top of the clamping block 51 . The clamping block 51 is designed to be semi-arc shaped.

[0027] A through hole is formed at the top of the fixing ring 55 , and the steel wire rope 52 passes through the inner cavity of the through hole and is movably connected to the inner cavity of the through hole.

[0028] like Figure 3 As shown, there are four steel wire ropes 52, which are evenly distributed on the top of the block 51. When the steel wire ropes 52 drive the block 51, the center tube 2 and the muffle tube 3 to lift, the stability of the lifting and disassembly of the center tube 2 and the muffle tube 3 can be well ensured. The block 51 is designed to be semi-arc-shaped, which is convenient for adapting to the outer walls of the center tube 2 and the muffle tube 3. The steel wire ropes 52 pass through the inner cavity of the through hole, and thus the movement of the fixing ring 55 can be limited, so that the fixing ring 55 can slide along the surface of the steel wire rope 52.

[0029] Example 3

[0030] Reference Figure 2 and 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0031] In this embodiment, one end of the steel wire rope 52 away from the clamping block 51 is fixedly connected to the connecting ring 521 , and the top of the connecting ring 521 can be connected to the external feeding system through a buckle.

[0032] One side of the clamping block 51 extends to the inner cavity of the clamping slot 4 and is movably connected to the inner cavity of the clamping slot 4 .

[0033] A clamping ring 31 is fixedly connected to the top of the muffle tube 3 , and the top of the clamping ring 31 extends to the inner cavity of the central tube 2 and is clamped with the inner cavity of the central tube 2 .

[0034] like Figure 2 and 4 As shown, the connecting ring 521 is fixed to the steel wire rope 52, and then when the external feeding system drives the connecting ring 521 to lift, the connecting ring 521 can drive the steel wire rope 52 to lift, and enter the inner cavity of the clamping groove 4 through the clamping block 51, so that the muffle tube 3 can be well clamped, and the lifting operation of the muffle tube 3 is convenient, and it is effectively prevented from falling. The clamping ring 31 enters the inner cavity of the center tube 2 for clamping, so that the connection and disassembly of the muffle tube 3 and the center tube 2 are convenient, and at the same time, the accuracy of the connection between the center tube 2 and the muffle tube 3 can be ensured to prevent the connection from being misplaced.

[0035] When in use, first pull the clamping block 51, the clamping block 51 drives the tension spring 54 to stretch and deform, and then the clamping block 51 moves downward along the central tube 2 and the muffle tube 3 until the clamping block 51 moves to the clamping slot 4, release the clamping block 51, the clamping block 51 cooperates with the restoring elastic force of the tension spring 54 to drive the connecting plate 53 and the clamping block 51 to retract inward, so that the clamping block 51 enters the inner cavity of the clamping slot 4 to achieve clamping, and by pulling the fixing ring 55, the fixing ring 55 moves downward along the wire rope 52 to contact and connect with the top of the central tube 2 , to achieve limiting, to prevent instability during later extraction, and then connect it to the external feeding system through the connecting ring 521, and then the external feeding system can cooperate with the connecting ring 521 to drive the wire rope 52, the block 51, the center tube 2 and the muffle tube 3 to gradually separate from the inner cavity of the heating furnace body 1 upward, thereby facilitating the removal of the center tube 2 and the muffle tube 3, and vice versa, the connecting ring 521 drives the wire rope 52, the block 51, the center tube 2 and the muffle tube 3 downward into the interior of the heating furnace body 1, and the installation can be achieved.
