Description

Technical Field

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

[0002] The Acheson graphitization furnace is a large industrial furnace used to convert carbonaceous materials into artificial graphite. It is used for the mass production of graphite crucibles. In the Acheson graphitization furnace, carbonaceous materials (such as carbon blanks and particles) are loaded into a long furnace body constructed of refractory materials to form a conductive furnace core. This furnace core is located in the center of the furnace body and is surrounded by insulation materials to maintain high temperatures. Conductive electrodes are provided at both ends of the furnace body, which are connected to a power supply to form an energized circuit. When current passes through the furnace core, heat is generated due to its resistance, causing the temperature in the furnace to rise to about 2200 to 2300 degrees Celsius, so that the carbon material undergoes a high-temperature heat treatment process and is converted into artificial graphite.

[0003] During the use of the Acheson graphitization furnace, a support 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 into the furnace to improve the workers' furnace loading efficiency; 2. After the Acheson graphitization furnace is roasted, the internal residue needs to be cleaned. 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.

[0004] Usually, a lifting device is installed on the top of the furnace of the Acheson graphitization furnace, and the platform carrying personnel is lowered into the furnace by the lifting device. However, since the mobile platform is supported by steel wire ropes, when the maintenance personnel move back and forth on the platform, the platform will shake, resulting in reduced safety. At the same time, when the crucible is loaded into the furnace, the weight on the platform changes, causing the platform to shake. Moreover, the rise and fall and lateral movement of the platform require the use of large lifting equipment, which will not only increase maintenance costs, but also increase cumbersome steps.

[0005] Therefore, it is necessary to propose an Acheson graphitization crucible furnace lifting and moving device to solve the above problems. Utility Model Content

A driving track can be arranged on the top of the Acheson graphitization furnace. The driving track is arranged parallel to the furnace. End beam walking devices 118 are arranged on both sides of the bottom of the support frame 101. The end beam walking device 118 is located on the driving track. A reduction motor is arranged on the end beam walking device 118. The output end of the reduction motor is connected to a moving wheel. The end beam walking device 118 drives the whole to move along the furnace. The lifting assembly 102 is mounted on the support frame 101, and the lifting platform 103 is connected to the lifting assembly 102. The lifting assembly 102 is fixed on the support frame 101. The lifting platform 103 can move up and down along the lifting frame 107 through the driving of the driving device 109 in the lifting assembly 102. The lifting assembly 102 drives the lifting platform 103 to move up and down on the support frame 101.

[0030] refer to Figure 1 , the support frame 101 is composed of a crossbeam 104, a platform support device 105, a guide assembly 106 and a lifting frame 107;

[0031] Specifically, the platform support device 105 is used to support the lifting frame 107. The interior of the lifting frame 107 passes through the first guide rail 120, and a moving rod 108 slides up and down. An extension frame 111 slides on the bottom outer wall. When the moving rod 108 moves up and down in the lifting frame 107, the moving rod 108 will not come into contact with the protrusion 114. At the same time, the moving rod 108 can also move to the second guide rail 112. When the moving rod 108 extends downward from the lifting frame 107, the sliding groove 115 will slide outside the protrusion 114. When it extends a certain distance, the trigger plate 116 at the top of the sliding groove 115 will come into contact with the protrusion 114, thereby driving the extension frame 111 to move upward and downward. The entire extension frame 111 moves downward, and at this time, the extension frame 111 moves downward along the outside of the lifting frame 107, indirectly increasing the length of the moving rod 108, thereby increasing the depth to which the lifting platform 103 can descend. The platform support device 105 is vertically connected to the middle of the crossbeam 104, and the lifting frame 107 is connected to one side of the platform support device 105. The interior of the lifting frame 107 is symmetrically connected with a first guide rail 120, and the first guide rail 120 and the second guide rail 112 are coaxially arranged, so that the moving rod 108 can smoothly move between the first guide rail 120 and the second guide rail 112, and the guide assembly 106 is connected to the top of the platform support device 105;

[0032] refer to Figures 2 to 4 , the four corners of the lifting platform 103 are connected with moving rods 108, and the interior of the lifting platform 103 is filled with heat-insulating materials to reduce the impact of the high temperature in the furnace on the maintenance personnel. The moving rod 108 is slidably connected to the symmetrical first guide rail 120. The lifting assembly 102 is composed of a driving device 109 and a steel wire rope 110. The driving device 109 is a device that can provide rotational power, preferably a reduction motor, and has a protection level of IP65 or above, an insulation level of H or above, and needs to be able to withstand a high temperature of 150 degrees continuously.

[0033] refer to Figures 2 to 4The outer wall of the lifting frame 107 is slidably connected to the extension frame 111 up and down. Specifically, the extension frame 111 moves up and down along the outer wall of the lifting frame 107, and a limiting device is provided between the lifting frame 107 and the extension frame 111 to prevent the extension frame 111 from falling off the lifting frame 107, which is not shown in the figure. The interior of the extension frame 111 is connected to the second guide rail 112, and the first guide rail 120 and the second guide rail 112 are located on the same axis. The bottom of the extension frame 111 is connected to a baffle 113, and the baffle 113 is connected to the extension frame 111. The moving rod 108 is not on the same axis, so no contact will be generated, but the protrusion 114 on the baffle 113 and the trigger plate 116 are on the same axis. When the moving rod 108 moves to the bottom, it will come into contact with the protrusion 114, thereby driving the extension frame 111 to move. The baffle 113 is provided with a protruding protrusion 114, and a sliding groove 115 is provided on one side of the moving rod 108. The top of the sliding groove 115 is connected to the trigger plate 116, and the trigger plate 116 can come into contact with the protrusion 114.

[0034] Specifically, refer to Figures 2 to 4 A reset component 117 is provided at the top of the extension frame 111. The reset component 117 is connected to the extension frame 111 and the lifting frame 107. When the lifting platform 103 moves upward, the extension frame 111 is pulled upward by the reset component 117, thereby moving upward and resetting. The reset component 117 is composed of a spring and a connecting plate. The connecting plates are connected to both ends of the spring, one of the connecting plates is connected to the top of the extension frame 111, and the other extension plate is fixed to the outer wall of the lifting frame 107.

[0035] Specifically, when the extension frame 111 is located at the top of the lifting frame 107 , the reset assembly 117 is also in a stretched state.

[0036] Specifically, the width of the sliding groove 115 is greater than that of the protrusion 114 , so that the sliding groove 115 does not come into contact with the protrusion 114 , but the trigger plate 116 at the top of the sliding groove 115 can come into contact with the protrusion 114 .

[0037] Specifically, refer to Figure 1 The bottoms of both sides of the cross beam 104 are connected with end beam traveling devices 118, which are mature equipment and will not be described in detail here, and drive the support frame 101 to move along the furnace direction.

[0038] Specifically, refer to Figure 3 A protective rod 119 is connected to the side of the extension frame 111 away from the lifting platform 103. When the extension frame 111 moves up and down, the protective rod 119 fixed on the extension frame 111 will also move accordingly, thereby playing a protective role for the staff.

[0039] In this embodiment, parallel traveling tracks are installed on both sides of the furnace of the Acheson graphitization furnace for the movement of the end beam traveling device 118. A reducer is installed on the end beam traveling device 118 to drive the support frame 101 to move, so that the entire equipment can move along the axial direction of the furnace to expand the working area of ​​the operator. Pedals are provided on both sides of the support frame 101, and guardrails are connected to the pedals to increase safety. A control cabinet and a cable harness automatic winding device are installed on one end of the beam 104.

[0040] After the maintenance personnel enter the lifting platform 103, the lifting assembly 102 is driven to move the lifting platform 103 downward so as to carry out work in the furnace.

[0041] When the moving rod 108 moves downward out of the lifting frame 107, the protrusion 114 will be located in the sliding groove 115. At the same time, the moving rod 108 will also move to the second guide rail 112. When the trigger plate 116 moves to contact the protrusion 114, the baffle 113 will drive the extension frame 111 to move downward, thereby extending the downward movement distance of the lifting platform 103. After the Acheson graphitization furnace is used to burn the boiler, a large amount of slag will exist in the furnace. The slag still has a certain temperature when it is cleaned. The overly long lifting frame 107 will be inserted into the slag, thereby affecting the lifting frame 107. The setting of the lifting frame 107 and the extension frame 111 can shorten the length of the guide device. After the cleaning personnel have cleaned the slag on the top layer, they can clean downward in sequence, so that the high-temperature slag will not affect the lifting frame 107.
