Description

Technical Field

[0001] The utility model relates to the technical field of protective support frames for electric furnaces, in particular to a protective support frame for electric furnaces. Background Art

[0002] An electric furnace is a heating furnace that converts the electrical energy in the furnace into heat to heat the workpiece. Electric furnaces can be divided into resistance furnaces, induction furnaces, arc furnaces, plasma furnaces, electron beam furnaces, etc. Compared with fuel furnaces, electric furnaces have the advantages of easy control of the furnace atmosphere, fast material heating, high heating temperature, easy temperature control, easier mechanization and automation of the production process, good labor hygiene conditions, high thermal efficiency and good product quality. Industrial electric furnaces are usually used in high-temperature processing processes, so protective support frames are required to prevent personnel from contacting high-temperature components and ensure the safety of operators.

[0003] Common protective support frames for electric furnaces usually need to be removed before maintenance begins. This process is time-consuming and labor-intensive, adding additional work steps. The process of removing and reinstalling the protective support frames takes up a lot of time, causing workers to be unable to focus on core inspection and maintenance tasks, which directly affects overall work efficiency. At the same time, during the removal of the protective support frames, workers may come into contact with high-temperature components of the electric furnace, increasing the risk of injury.

[0004] Therefore, for the above-mentioned protective support frame for electric furnaces, it is necessary to remove the protective support frame before maintenance, which not only affects the overall work efficiency, but also increases the risk of injury. A protective support frame for electric furnaces can be designed. When the electric furnace needs to be inspected and maintained, the electric slide rail is started to drive the upper L-shaped frame and the protective frame to move, thereby exposing most of the electric furnace. Inspection and maintenance work can be carried out without removing the protective frame, which improves the work efficiency of the staff, reduces the chance of the staff contacting high-temperature components, and reduces work risks to solve the above problems. Utility Model Content

[0005] In order to overcome the common problem of protective support frames for electric furnaces, the protective support frames need to be removed before maintenance, which not only affects the overall work efficiency but also increases the risk of injury.

[0006] The technical solution of the utility model is: a protective support frame for an electric furnace, comprising a base plate; also comprising an electric slide rail, a moving block, an electric push rod, a mounting part, an L-shaped frame and a guard frame, a mounting cylinder is fixedly arranged at the center of the upper end surface of the base plate, two electric slide rails are respectively arranged at intervals on both sides of the mounting cylinder on the upper end surface of the base plate, the upper surfaces of the four electric slide rails are respectively slidably connected with a moving block, the upper end surfaces of the two moving blocks are fixedly provided with a fixing plate, the upper end surfaces of the two fixing plates are respectively fixed with a mounting plate at the center of the upper end surfaces, the upper end surfaces of the two mounting plates are respectively fixed with an insulating cylinder, the inner bottom surfaces of the two insulating cylinders are respectively fixedly provided with an electric push rod, the output ends of the two electric push rods are respectively fixedly connected with a mounting part, the upper end surfaces of the two mounting parts are respectively fixed with an L-shaped frame, the side surfaces of the two L-shaped frames close to the mounting cylinder are respectively spaced apart with multiple guard frames, and the end surfaces of the multiple guard frames away from the L-shaped frames to which they are connected are respectively fixed with a buffer pad.

[0007] Preferably, when the electric furnace needs to be inspected and maintained, it is only necessary to start the electric slide rail to drive the moving block to move away from the installation cylinder, thereby driving the upper L-shaped frame and the guard frame to move, so that most of the electric furnace is exposed, and inspection and maintenance work can be carried out without removing the guard frame, which simplifies the work process, making it convenient for staff to carry out inspection and maintenance work, significantly improving the work efficiency of staff, reducing the chance of staff contacting high-temperature components, and reducing work risks. At the same time, the electric push rod can drive the L-shaped frame and the guard frame to adjust the height, which can adapt to the use of electric furnaces of different specifications, further improving the practicality of the device.

[0008] Preferably, a damper is installed on the inner bottom surface of the mounting tube, a fixed block is installed on the upper end of the damper, and a buffer spring is movably connected to the outer surface of the damper. The electric furnace may vibrate due to the thermal expansion and contraction effect during the heating process. By using a damper and a buffer spring, the impact of this vibration on the electric furnace can be effectively reduced, thereby extending its service life.

[0009] Preferably, the upper end face of the fixed block is fixedly connected to one end of a connecting rod, and the end face of the connecting rod away from the fixed block is fixedly provided with a mounting part 2, and the upper end face of the mounting part 2 is installed with a placing platform. The placing platforms of different specifications can be replaced through the mounting part 2 to adapt to electric furnaces of different specifications, so that the device can be adapted to most electric furnaces for use.

[0010] Preferably, the electric furnace body is placed on the upper end surface of the placement platform, and two L-shaped frames are fixedly installed with an electric push rod 2 close to the inner surface of the electric furnace body, which is installed on the placement platform through the electric furnace body. The damper and buffer spring are arranged under the placement platform, so that the vibration generated by the electric furnace body is transmitted to the damper and buffer spring through the placement platform, and the vibration is absorbed by the damper and buffer spring.

[0011] Preferably, the output ends of the two electric push rods 2 are respectively fixedly connected to a mounting part 3, and a ring-shaped support plate is respectively installed on the side surface of the two mounting parts 3 close to the electric furnace body. When the two electric push rods 2 are started, the two electric push rods 2 drive the mounting part 3 to move toward the electric furnace body, thereby driving the ring-shaped support plate to move. The electric furnace body is fixed and limited to the left and right by the two ring-shaped support plates, so that the device fixes the electric furnace body stably.

[0012] Preferably, the curvature of the annular support plate is consistent with the curvature of the outer surface of the electric furnace body, and an air gap is provided inside the bottom plate. The annular support plate is installed through mounting member three, and the annular support plate matching the electric furnace body can be replaced so that the curvature of the annular support plate is consistent with the curvature of the outer surface of the electric furnace body, further improving the effect of fixing and limiting the electric furnace body. The air gap acts as a good thermal insulation layer, reducing heat conduction to the ground, effectively preventing the high temperature generated when the electric furnace is working from being directly transferred to flammable locations such as the ground, which may cause the risk of fire.

[0013] Preferably, the guard frame and the bottom plate are made of alloy steel, and the interior of the guard frame is filled with thermal insulation material. Using alloy steel as the material of the guard frame and the bottom plate further improves the structural strength of the device, and at the same time filling the interior of the guard frame with thermal insulation material effectively blocks the transfer of heat.
