[0044] Example 1

[0045] Referring to Figure 1 As shown in the drawings, the present embodiment provides a furnace production system beneficial to safe and efficient operation and maintenance, which comprises four furnaces 1, three working positions 2, three longitudinal tracks 3, one transverse track 4, three transfer positions 5, one maintenance area 6, one standby area 7, and four transfer vehicles 8.

[0046] Among them, three of the four furnaces are working furnaces, and one is a standby furnace. The three working furnaces are installed on the three working positions 2, and each working position 2 leads out a longitudinal track 3. The transverse track 4 is arranged perpendicularly across each longitudinal track 3, and the intersection forms the three transfer positions 5. The transfer vehicles 8 are divided into three longitudinal transfer vehicles and one transverse transfer vehicle. The longitudinal transfer vehicles are adapted to the longitudinal tracks, and the transverse transfer vehicle is adapted to the transverse track, and they can all reciprocate on the corresponding tracks.

[0047] The working position 2 of the furnace is the normal production position of the furnace 1, the inside of the furnace is filled with high-temperature molten metal, and the inductor of the furnace has high voltage during operation. Therefore, in order to ensure safety, the regulations generally require that there should be no personnel-intensive area or work area within a certain distance radius from the furnace. However, in the case of the traditional furnace production system, the maintenance work of the furnace is usually carried out on site after power failure, and the working furnace near the maintenance furnace continues to produce, which has certain safety hazards.

[0048] In this embodiment, the maintenance area 6 and the standby area 7 are arranged at both ends of the transverse track 4, and the maintenance area 5 is arranged at a position away from any working position and outside the distance radius meeting the safety regulations.

[0049] In this application, the number of maintenance positions in the maintenance area 6 and the number of standby positions in the standby area 7 can be set according to the number of furnaces. In this embodiment, Figure 1 As shown, there is one maintenance position and one standby position, and in other embodiments, the maintenance area 6 can be provided with 2-4 maintenance positions, and the standby area 7 can be provided with 2-4 standby positions. The maintenance positions are connected by tracks, the standby positions are connected by tracks, and when the transfer trolley 8 transfers the furnaces in the maintenance area 7 and the standby area 6, the furnace closest to the transfer position 5 is preferentially transferred.

[0050] The working position 2, the transfer position 5, the maintenance position, and the standby position are each provided with a pedestal for mounting, fixing, or temporarily supporting the furnace 1. The transfer trolley 8 is provided with a supporting mechanism for lifting the furnace to make it disengage from the pedestal. The supporting mechanism can use existing mechanisms, for example, in one embodiment, the supporting mechanism includes multiple jacks, or uses a lifting platform powered by a jack.

[0051] The bottom of the furnace 1 is reserved with a space allowing the transfer trolley 8 to pass through and be lifted, which can be the space of the bottom of the furnace 1 itself, the space left on the pedestal, or a combination of both. The furnace 1 is provided with a plurality of support points for bearing the lifting of the supporting mechanism of the transfer trolley. These support points are arranged in the space at the bottom of the furnace, or other parts of the furnace that can be lifted by the supporting mechanism. The supporting mechanism lifts and presses the support points to lift the furnace 1 away from the pedestal. Similarly, the supporting mechanism can lower the furnace 1 to the pedestal.

[0052] The longitudinal track 3 passes through the ground projection of the working position 2, so that the transfer trolley can use the track to walk to the space below the furnace to complete the lifting action.

[0053] The transfer trolley 8 fixes the carrying furnace 1 by an anti-skid fixing mechanism, which mainly avoids the furnace from falling off during the transfer process. The anti-skid fixing mechanism can be achieved in various ways, for example, in one embodiment, the anti-skid fixing mechanism can be a bolt and nut to fix the furnace 1 to the transfer trolley 8, in another embodiment, the anti-skid fixing mechanism is a hydraulic lock or a hydraulic clamp, and in another embodiment, the anti-skid fixing mechanism is a restraint belt.

[0054] In this embodiment, the connection mode between the maintenance area and the transverse track is that the maintenance area is arranged at or near a position that can be reached by the transverse track. The connection mode between the standby area and the transverse track is that the standby area is arranged at or near a position that can be reached by the transverse track.

[0055] The working principle of this embodiment is as follows:

[0056] When a working furnace needs to be taken offline for maintenance, the water and electricity connection of the working furnace is disconnected, the longitudinal transfer trolley on the longitudinal track corresponding to the working furnace is controlled to drive into the lower part of the furnace, the support mechanism of the longitudinal transfer trolley lifts the furnace and fixes it through the anti-skid fixing mechanism, and then the longitudinal transfer trolley is transported to the corresponding transfer position; after the longitudinal transfer trolley puts down the furnace at the transfer position, the longitudinal transfer trolley drives away from the transfer position.

[0057] Then, the transverse transfer trolley on the transverse track is controlled to drive into the lower part of the furnace, the transverse transfer trolley lifts the furnace and fixes it through the anti-skid fixing mechanism, and then the transverse transfer trolley is transported to the maintenance area for maintenance work by the staff; the transverse transfer trolley transports the furnace in the standby area to the corresponding transfer position, and the corresponding longitudinal transfer trolley transports the furnace to the corresponding working position for installation, thereby completing the replacement of the induction furnace;

[0058] After the furnace transported to the maintenance area is maintained by the staff, the transverse transfer trolley transports the furnace to the standby area at the other end, waiting for the next induction furnace replacement work.

[0059] Embodiment 2:

[0060] Referring to Figure 2 The difference between this embodiment and embodiment 1 is that this embodiment includes three furnaces 1, two working positions 2, two longitudinal tracks 3, one transverse track 4, two transfer positions 5, two maintenance areas 6, two standby areas 7, and three transfer trolleys 8.

[0061] Two of the three furnaces are working furnaces, and one is a standby furnace. Two working furnaces correspond to two working positions and two longitudinal tracks. The transfer car is divided into two longitudinal transfer cars and one transverse transfer car. The maintenance area is arranged at the other end of the longitudinal track corresponding to the working position, away from the working position and outside the distance radius that meets the safety specification. The standby area is arranged at both ends of the transverse track. As in Embodiment 1, in this embodiment, the number of maintenance positions of the maintenance area 6 and the number of standby positions of the standby area 7 can be set according to the number of furnaces.

[0062] The working principle of this embodiment is:

[0063] When a working furnace needs to be taken offline for maintenance, disconnect the water and electricity connection of the working furnace, and control the longitudinal transfer car on the longitudinal track corresponding to the working furnace to drive into the lower part of the furnace, lift the furnace and fix it through the anti-slip fixing mechanism, and then transport it to the corresponding maintenance area, waiting for the maintenance work of the workers;

[0064] By controlling the transfer car on the transverse track to transport the already repaired or brand new furnace on the standby area at either end of the transverse track to the corresponding transfer position, and then controlling the corresponding longitudinal transfer car to transport the furnace to its working position for installation, the replacement of the induction furnace is completed;

[0065] After the furnace transported to the maintenance area is repaired by the workers, the furnace is transported to the nearest standby area through the transfer of the longitudinal transfer car and the transverse transfer car at the transfer position, waiting for the next induction furnace replacement work.

[0066] Embodiment 3:

[0067] Referring to Figure 3 The difference between this embodiment and Embodiment 1 is that this embodiment includes: four furnaces 1, three working positions 2, three longitudinal tracks 3, one transverse track 4, three transfer positions 5, one maintenance area 6, one standby area 7, and one transfer car 8.

[0068] The transfer car 8 can switch between the longitudinal track 3 and the transverse track 4 and continue to walk, realizing the above functions in at least two embodiments.

[0069] One of the embodiments is that the transfer vehicle has longitudinal walking components, transverse walking components and switching mechanisms, the longitudinal walking components are adapted to the longitudinal tracks, the transverse walking components are adapted to the transverse tracks, and the switching mechanisms switch to the corresponding walking components to work according to the tracks on which the transfer vehicle needs to walk. The walking components are wheels and driving motors adapted to the tracks, and the switching mechanisms can use controllers. When walking on the longitudinal tracks, the controller controls the motors of the longitudinal walking components to work, and the motors of the transverse walking components do not work. When reaching the transfer position, the wheels of the transverse control components are aligned with the transverse tracks, and then the controller stops the longitudinal walking components and makes the transfer vehicle walk on the transverse tracks by the transverse walking components. The walking components and the controller can be realized by referring to the prior art, and will not be further introduced.

[0070] Another embodiment is that the transfer vehicle has walking mechanisms that can walk on longitudinal tracks and transverse tracks. The walking mechanisms are wheels and driving motors that are adapted to the longitudinal tracks and the transverse tracks. The walking mechanisms are provided with wheel in-place steering mechanisms to realize steering from the longitudinal tracks to the transverse tracks and from the transverse tracks to the longitudinal tracks at the transfer position. The wheel in-place steering mechanisms can be realized by referring to the prior art, and will not be further introduced.

[0071] Three of the four furnaces in this embodiment are working furnaces, and one is a standby furnace. The three working furnaces correspond to three working positions and three longitudinal tracks. The maintenance area and the standby area are arranged at the two ends of the transverse tracks, and the maintenance area is arranged at a position away from any working position and outside the distance radius that meets the safety specifications. As in Embodiment 1, the number of maintenance positions of the maintenance area 6 and the number of standby positions of the standby area 7 in this embodiment can be set according to the number of furnaces.

[0072] The working principle of this embodiment is that when a working furnace needs to be taken offline for maintenance, the water and electricity connection of the working furnace is disconnected. The transfer vehicle can be controlled to drive under the furnace, lift the furnace and fix it by the anti-slip fixing mechanism, and then transport it to the corresponding transfer position;

[0073] The transfer vehicle completes the in-place track changing action from the longitudinal track to the transverse track at the transfer position by the wheel in-place steering or the switching mechanism, so as to continue to transport the furnace to the maintenance area at one end of the transverse track for maintenance work by the staff. After the transfer vehicle successfully places the furnace in the maintenance area, it continues to drive into the standby area at the other end of the transverse track and transports the furnace in the standby area to the corresponding transfer position;

[0074] The transfer vehicle again completes the in-place track changing action from the transverse track to the longitudinal track at the transfer position by the wheel in-place steering or the switching mechanism, and finally transports the furnace to the working position at one end of the longitudinal track for installation, completing the replacement of the induction furnace;

[0075] After the furnace is transported to the maintenance area and is finished by the staff, the furnace can be transported to the standby area at the other end by the transfer car, waiting for the next induction furnace replacement work.

[0076] Embodiment 4:

[0077] Reference Figure 4 The difference between this embodiment and embodiment 2 is that, in this embodiment, the standby area is arranged at the other end of the longitudinal track corresponding to the working position, and the maintenance area is arranged at both ends of the transverse track, away from the working position and outside the distance radius meeting the safety specifications. As in embodiment 1, the number of maintenance positions of the maintenance area 6 and the number of standby positions of the standby area 7 in this embodiment can be set according to the number of furnaces.

[0078] The working principle of this embodiment is:

[0079] When a working furnace needs to be taken offline for maintenance, disconnect the water and electricity connection of the working furnace, control the longitudinal transfer car on the longitudinal track corresponding to the working furnace to drive under the furnace, the supporting mechanism of the longitudinal transfer car lifts the furnace and fixes it through the anti-skid fixing mechanism, and then transports it to the corresponding transfer position; after the longitudinal transfer car puts down the furnace at the transfer position, it drives away from the transfer position (it is recommended to drive to the standby area 7 corresponding to the working position 2);

[0080] Control the transverse transfer car on the transverse track to drive under the furnace, lift the furnace and fix it through the anti-skid fixing mechanism, and then transport it to the nearest maintenance area 6 for maintenance work by the staff; then transport the furnace with the maintenance number before the standby area 7 or a brand new furnace to the corresponding working position for installation through the longitudinal transfer car, complete the replacement of the induction furnace;

[0081] After the furnace transported to the maintenance area is finished by the staff, the furnace is transported to the nearest standby area through the transfer of the transverse transfer car and the longitudinal transfer car at the transfer position, waiting for the next induction furnace replacement work.

[0082] In one embodiment, when multiple furnaces need to be replaced, the first furnace to be taken offline is transferred to the idle maintenance position at the farthest end of the corresponding track first, and then arranged from far to near on each idle maintenance position; when transferring the furnace from the maintenance area to the standby area, the nearest maintenance position is preferred to the idle standby position farthest from the standby area; when transferring the furnace from the standby position to the working position, the nearest standby position is preferred to the working position.

[0083] The above merely illustrates the specific implementation manners of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
