Description

Technical Field

[0001] The utility model relates to the technical field of a crucible mobile platform, and more specifically to a crossbeam lifting device for transferring an Acheson graphitization crucible. Background Art

[0002] Acheson graphitization furnace is a large industrial furnace used to convert carbonaceous materials into artificial graphite, and is used to mass produce graphite crucibles. During the use of the Acheson graphitization furnace, a production work platform will be set up and extended into the furnace for workers to work in the furnace. The set support platform has multiple uses: 1. It can provide workers with a convenient mobile platform when loading the crucible to improve the efficiency of workers loading the furnace; 2. After the Acheson graphitization furnace is roasted, the internal residue needs to be cleaned, and the support platform can be used to load the cleaned residue to improve the cleaning efficiency; 3. After the Acheson graphitization furnace is used, the internal sensor electrodes need to be maintained to improve the service life of the Acheson graphitization furnace.

[0003] A lifting device is provided on the top of the furnace of the Acheson graphitization furnace, or a lifting device such as a winch is used on the mobile platform to drive the platform up and down, so as to facilitate the workers to move in the furnace. For example, the Chinese patent with application number 202321039710.6 discloses a boiler furnace maintenance lifting platform, which is provided with a winch and a traction rope. One end of the traction rope is connected to a suspension device preset on the top of the boiler, and the other end of the traction rope is wound around the winch. The winch is connected to the load-bearing beam, and the rise and fall of the platform are controlled by the retracting and releasing of the winch. However, the boiler furnace maintenance lifting platform still has the following problems: the platform is fixed to the winch by a traction rope, and the platform will shake during use, especially when the crucible is moved in and out. Since the crucible is heavy, the supporting platform will shake to varying degrees during transportation. At the same time, a lower limit device is provided on the lifting platform, and the platform will stop moving when it reaches the lower limit. Some limit devices will be provided with a supporting structure, which can support the platform and prevent the platform from continuing to move downward. However, the current limiting structure is not easy to adjust. It can only support the platform after the platform reaches the bottom and contacts the lower limit.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4A crossbeam lifting device for transferring an Acheson graphitizing crucible comprises a support frame 101, a lifting assembly 102 and a lifting platform 103. The support frame 101 is horizontally placed on the top of the Acheson graphitizing furnace. Both sides of the top of the Acheson graphitizing furnace are provided with driving tracks parallel to the Acheson graphitizing furnace. Both sides of the bottom of the support frame 101 are provided with end beam walking devices. A reducer and a moving wheel are installed inside the end beam walking device. The end beam walking device drives the support frame 101 to move axially along the driving track to expand the crucible. The movable area of ​​the large lifting platform 103, the lifting assembly 102 is installed on the support frame 101, and the lifting platform 103 is connected to the lifting assembly 102. Specifically, the lifting platform 103 is lifted up and down on the support frame 101, and the support frame 101 can move horizontally on the Acheson graphitization furnace to complete the work at any position in the furnace. The lifting assembly 102 drives the lifting platform 103 to move up and down on the support frame 101, and the end beam walking devices are arranged on both sides of the bottom of the support frame 101;

[0026] refer to Figure 1 The support frame 101 includes a lifting frame 104, and the inner wall of the lifting frame 104 is symmetrically provided with guide rails. The lifting platform 103 includes a crossbeam lifting plate 123 and lifting rods 105 fixed at four corners. The guide rails are used to stabilize the up and down sliding of the lifting rods 105. The length of the guide rails is the same as that of the lifting frame 104. The lifting rod 105 can move downward from the lifting frame 104 for a distance to increase the descending distance of the lifting platform 103, but it cannot be completely separated from the lifting frame 104. The lifting rod 105 is slidably connected to the slide rails;

[0027] The crossbeam lifting plate 123 can move up and down in the lifting frame 104 through the lifting rods 105 on the four sides, so as to carry out the work in the furnace. However, due to the heavy crucible, the crossbeam lifting plate 123 will still shake during transportation, which will affect the stability of the guide rail for a long time. The following provides a structure that combines the lifting rod 105 and the lower limit device together, which can support the crossbeam lifting plate 123 and is also easy to adjust: Figures 1 to 3 A fixed support block 106 is symmetrically connected to one side of the lifting frame 104, and the fixed support block 106 is located on both sides of the lifting rod 105.

[0028] The distance between the two movable support blocks 107 can be adjusted by the quick-release screws 110, and the symmetrical movable support blocks 107 can be fixed at any height on the lifting rod 105. When the movable support blocks 107 are set lower, the downward movement distance of the beam lifting plate 123 is shorter. When in contact with the fixed support block 106, the fixed support block 106 can support the beam lifting plate 123 through the movable support block 107. At this time, the lifting rod 105 can be connected to the lifting frame 104 through the fixed support block 106 and the movable support block 107 to avoid the lifting rod 105 shaking on the guide rail.

[0029] Specifically, refer to Figure 2 and Figure 3 A fixed plate 111 is provided inside the lifting rod 105, and a through groove 112 penetrating into the inside is provided on one side of the lifting rod 105.

[0031] Specifically, refer to Figures 1 to 3 , positioning grooves 116 are opened on both sides of the lifting rod 105, and the positioning grooves 116 are located on both sides of the through groove 112. When the symmetrical connecting plate 109 drives the movable support block 107 to move toward the middle, the positioning block 117 will be inserted into the positioning groove 116, thereby fixing the movable support block 107 on the lifting rod 105, and the side of the movable support block 107 close to the lifting rod 105 is connected to the positioning block 117 located in the positioning groove 116.

[0032] Specifically, refer to Figure 1 and Figure 4 The support frame 101 also includes a structural support 118, a platform support device 119 and a guide assembly 120.

The other end of the wire rope 122 is connected to the lifting rod 105, and the wire rope 122 passes through the guide assembly 120.

[0034] In this embodiment, the lifting assembly 102 is fixed on the support frame 101, and the output end of the driving device 121 drives the end of the wire rope 122 to move up and down through the roller, thereby driving the beam lifting plate 123 to lift and lower, so that workers can work in the furnace. The support frame 101 is equipped with a lifting ring, and the entire device can be lifted by a lifting equipment to perform operations in multiple Acheson graphitization furnaces.

[0035] When the crucible needs to be transported, the movable support block 107 is fixed to the specified position of the lifting rod 105 by the quick-release screw 110. When the beam lifting plate 123 descends to a certain extent, the movable support block 107 will come into contact with the fixed support block 106. At this time, the fixed support block 106 can support the beam lifting plate 123 through the movable support block 107 to improve the stability when transporting the crucible.
