Description

Technical Field

[0001] This utility model relates to non-metallic electric arc furnaces, and in particular to a support frame for the installation of non-metallic electric arc furnaces. Background Technology

[0002] During the smelting process in a non-metallic electric arc furnace, the molten metal inside can suddenly rise due to factors such as material collapse and boiling. To prevent this sudden surge, a tilting design at a certain angle is typically used. To achieve this, hydraulic cylinders are usually employed as rear support columns. Throughout the smelting process, these support cylinders bear the entire weight of the furnace, placing high demands on them. If a leak occurs, a pneumatic hydraulic cylinder must be used to readjust the tilt angle. Furthermore, when shutting down the furnace, a support mechanism is required to prop it up, which is extremely inconvenient. Utility Model Content

[0003] This utility model provides a support frame for the installation of a non-metallic electric arc furnace. Its purpose is to maintain the backward tilt angle of the electric arc furnace by supporting the rear legs, and to reduce the load and pressure on the support cylinder.

[0004] To achieve the above objectives, embodiments of this utility model provide a support frame for the installation of a non-metallic electric arc furnace, comprising:

[0005] The support mechanism includes two front support legs and two rear support legs. The length of the two front support legs is greater than the length of the two rear support legs. The front support legs and the rear support legs are vertically arranged so that the support mechanism is rectangular.

[0006] The sliding mechanism slides in a direction perpendicular to the length of the supporting rear leg;

[0007] The electric furnace mounting plate has one end hinged to the front support leg and the other end for attaching to the sliding mechanism or the rear support leg.

[0008] A pushing mechanism is disposed between the front support leg and the rear support leg, and the pushing mechanism is used to push the electric furnace mounting plate to rotate.

[0009] Preferably, the electric furnace mounting plate is positioned on a first plane when it overlaps the sliding mechanism, and on a second plane when it overlaps the supporting rear leg, with the angle between the first plane and the second plane being 5°.

[0010] Preferably, each of the supporting front legs is provided with a first hinge seat at its top end, and the first hinge seat is connected to the electric furnace mounting plate.

[0011] Preferably, the support frame for installing a non-metallic electric arc furnace further includes a bottom surface, the support mechanism is disposed on the bottom surface, one end of the pushing mechanism is hinged to the bottom surface, and the other end is hinged to the electric furnace mounting plate.

[0012] Preferably, the sliding mechanism includes a crossbeam, which is perpendicular to the length direction of the supporting rear leg and is disposed at the top of the supporting rear leg. A slider is disposed on the crossbeam, and the slider slides along the length direction of the crossbeam.

[0013] Preferably, the sliding mechanism is further provided with a power unit, which drives the slider to move.

[0016] Preferably, the actuating mechanism is a hydraulic cylinder.

[0017] The above-mentioned solution of this utility model has the following beneficial effects:

[0018] In this application, by setting support front legs and support rear legs at different heights, the electric furnace mounting plate can be maintained in a horizontal state or a backward tilted state. When maintaining the backward tilted state, the electric furnace mounting plate overlaps the top of the support rear leg; when maintaining the horizontal state, the electric furnace mounting plate overlaps the sliding mechanism.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1 and 2 As shown, an embodiment of this utility model provides a support frame for installing a non-metallic electric arc furnace, including a support mechanism 1, a sliding mechanism 2, an electric furnace mounting plate 3, and a pushing mechanism 4. The support mechanism 1 includes two front support legs 11 and two rear support legs 12. The length of the two front support legs 11 is greater than the length of the two rear support legs 12. The two front support legs 11 and the two rear support legs 12 are arranged in a rectangular array, making the support mechanism 1 rectangular in shape. The aforementioned sliding mechanism 2 is disposed on the rear support legs 12 and slides along a direction perpendicular to the rear support legs 12. One end of the electric furnace mounting plate 3 is hinged to the front support legs 11, and the other end overlaps the sliding mechanism 2 or the rear support legs 12. The pushing mechanism 4 is disposed between the front support legs 11 and the rear support legs 12, and under the pushing of the pushing mechanism 4, the electric furnace mounting plate 3 can rotate around the hinge point between the electric furnace mounting plate 3 and the front support legs 11.

[0026] When the electric furnace mounting plate 3 overlaps the sliding mechanism 2, the electric furnace mounting plate 3 is in the first plane; when the electric furnace mounting plate 3 overlaps the supporting rear leg 12, the electric furnace mounting plate 3 is in the second plane. The angle between the first plane and the second plane is the backward tilt angle of the electric furnace mounting plate 3. Preferably, the backward tilt angle is 5°.

[0027] In this application, in order to enable the electric furnace mounting plate 3 to rotate better, a first hinge seat 13 is provided at the top of each supporting front leg 11. The first hinge seat 13 is connected to the electric furnace mounting plate 3, so that the electric furnace mounting plate 3 can rotate around the first hinge seat 13.

[0028] The support frame for installing a non-metallic electric arc furnace also includes a bottom surface 5. The aforementioned support mechanism 1 is disposed on the bottom surface 5, and the projections of the two front support legs 11 and the two rear support legs 12 on the bottom surface 5 are the four vertices of a rectangle, respectively. One end of the aforementioned pushing mechanism 4 is hinged to the bottom surface 5, and the other end is hinged to the electric furnace mounting plate 3. In this embodiment, the pushing mechanism 4 is a hydraulic cylinder. This hydraulic cylinder can push the electric furnace mounting plate 3 to rotate by extending or shortening.

[0029] The aforementioned sliding mechanism 2 includes a crossbeam 21, which is arranged perpendicular to the length direction of the supporting rear leg 12 and is located at the top of the supporting rear leg 12. A slider 22 is slidably arranged on the crossbeam 21, which can slide along the length direction of the crossbeam 21, thereby enabling the electric furnace mounting plate 3 to overlap on the slider 22 or the supporting rear leg 12.

[0030] Furthermore, the sliding mechanism 2 is also equipped with a power unit 23, which drives the slider 22 to slide on the crossbeam 21. In this embodiment, the power unit 23 is an electric push rod, which is located at one end of the crossbeam 21, and the slider 22 is located at the other end of the crossbeam 21. Preferably, the top of the supporting rear leg 12 is located in the middle of the crossbeam 21. When the slider 22 is driven by the electric push rod, it can move from one end of the crossbeam 21 to the middle of the crossbeam 21. When the slider 22 is located in the middle of the crossbeam 21, the electric furnace mounting plate 3 overlaps the slider 22. At this time, the projections of the slider 22 and the supporting rear leg 12 on the bottom surface 5 coincide, resulting in the best support effect and reducing the pressure on the crossbeam 21.

[0031] Furthermore, to ensure that the movement path of the slider 22 does not deviate, a slide rail 24 is also provided on the crossbeam 21. The length direction of the slide rail 24 is the same as that of the crossbeam 21. A guide wheel 25 is provided below the slider 22. The guide wheel 25 rolls on the slide rail 24 to reduce the friction between the slider 22 and the slide rail 24.

[0032] In this application, the electric furnace mounting plate 3 includes a first state and a second state. In the first state, the electric furnace mounting plate 3 overlaps the supporting rear leg 12. At this time, the electric furnace mounting plate 3 is tilted backward. At this time, the supporting rear leg 12 is the main supporting component of the electric furnace mounting plate 3. The weight of the electric furnace mounting plate 3 acts on the supporting rear leg 12 and the supporting front leg 11. There is no need for the pushing mechanism 4 to provide support, which reduces the load on the pushing mechanism 4 and protects the pushing mechanism 4.

[0033] In the second state, the slider 22 slides to the middle of the crossbeam 21 under the action of the power unit 23. At this time, the electric furnace mounting plate 3 overlaps with the sliding mechanism 2 (i.e., overlaps with the slider 22), and the electric furnace mounting plate 3 is in a horizontal state, which facilitates operations such as feeding the electric arc furnace. At this time, the weight of the electric furnace mounting plate 3 acts on the supporting rear leg 12, the supporting front leg 11, and the sliding mechanism 2. Similarly, the pushing mechanism 4 is not required for support. The pushing structure only provides rotational power when the electric furnace is installed and rotated, which can effectively avoid damage such as oil leakage caused by the pushing structure being under load for a long time.

[0034] In this application, by setting a sliding mechanism 2 on the supporting rear leg 12, the sliding mechanism 2 can be used to make the electric furnace mounting plate 3 in a horizontal or backward tilted state, which can maintain the stability of the electric furnace mounting plate 3. At the same time, the supporting rear leg 12 or the supporting rear leg 12 and the sliding mechanism 2 are the main components supporting the electric furnace mounting plate 3, and there is no need to consider problems such as oil leakage. The support effect and support time are better than the scheme of using a hydraulic cylinder as support.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
