Description

Technical Field

[0001] The utility model belongs to the technical field of electric furnace maintenance, and in particular relates to a high-temperature electric furnace maintenance device. Background Art

[0002] High-temperature electric furnaces are important tools in fire assaying. Their maximum operating temperature is around 1200°C, and their minimum operating temperature is around 800°C. These furnaces operate at high temperatures for extended periods, placing a significant strain on the furnace bricks.

[0003] After long periods of operation, the hearth bricks of high-temperature electric furnaces can peel, crack, or burn out, necessitating repairs and rebuilding of the furnace. Because the insulation bricks used to support the hearth bricks are lightweight, high-aluminum bricks, their dimensions do not fully meet the requirements of high-temperature electric furnaces. These bricks must be cut and polished to standard sizes. This process generates a lot of dust and requires operators to manually carry the lightweight, high-aluminum bricks to the operating table, posing a safety hazard and wasting manpower and resources.

[0008] A linkage lifting assembly includes a pulling and winding device provided on the surface of the platform, a hydraulic telescopic member connecting the vehicle base and the material receiving platform, a liquid storage member provided on the vehicle base and internally provided with a liquid medium, and a propulsion type liquid delivery structure provided inside the liquid storage member. The liquid storage member is in communication with the interior of the hydraulic telescopic member, and the propulsion type liquid delivery structure is capable of inputting the liquid medium in the liquid storage member into the hydraulic telescopic member.

[0009] The propulsion type liquid delivery structure can be connected to the output end of the pulling and winding device through a rope. The surface of the platform is provided with a limiting groove adapted to the feeding trolley. After the feeding trolley enters the limiting groove, the pulling and winding device can pull the propulsion type liquid delivery structure through the rope to move inside the liquid storage part.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the pulling and winding device includes a winding motor, a winding drum arranged at the output end of the winding motor, and a pulling rope arranged on the winding drum.

[0012] Furthermore, the push-type liquid delivery structure includes a liquid pushing piston arranged inside the liquid storage component, and a connecting component arranged at one end of the liquid pushing piston away from the liquid storage component, and the connecting component can be connected to the pulling rope.

[0013] Furthermore, an air pressure channel communicating with the outside is provided inside the liquid storage component.

[0014] Furthermore, a hook is provided at one end of the pulling rope away from the winding drum, and a hanging ring adapted to the hook is provided on the surface of the connecting piece.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model uses the linkage lifting component to enable the operator to place the lightweight high-aluminum bricks to be processed on the feeding trolley when the operator needs to cut and grind the lightweight high-aluminum bricks. After the feeding trolley is pushed to the maintenance platform, the feeding trolley is pulled into the maintenance platform via the pulling rope. After the feeding trolley is completely inside the maintenance platform, the pulling and winding device prompts the propulsion type liquid feeding structure to inject the liquid medium in the liquid storage part into the hydraulic telescopic part, so that the hydraulic telescopic part is extended as a whole, prompting the receiving platform to rise to the table surface of the maintenance platform. The operator does not need to manually carry the lightweight high-aluminum bricks. After the processing is completed, the feeding trolley is pushed out from the maintenance platform, and the next feeding trolley loaded with lightweight high-aluminum bricks to be processed can be sent into the maintenance platform. The operation is more efficient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
