Description

Technical Field

[0001] The utility model relates to the field of crucible furnace production, in particular to a crucible furnace fixture overhead crane. Background Art

[0002] A crucible furnace is the simplest smelting equipment, mainly used for melting non-ferrous metals with relatively low melting points, such as copper, aluminum and their alloys. In this kind of melting furnace, the alloy is melted in the crucible, and the heat is transferred from the crucible to the furnace charge. The furnace charge and combustion products do not come into direct contact, so the chemical composition of the alloy is hardly affected by the furnace gas, and the temperature of the alloy liquid is also relatively uniform. When the crucible furnace is in production, due to its large weight, it needs to be lifted out of the production position by a lifting device. The existing lifting device requires manual operation to pass the steel wire rope through the crucible furnace, and then lift and place it by the lifting device. In this process, only one crucible furnace can be lifted at a time, and the whole operation speed is slow. Moreover, the newly produced crucible furnace still has a certain amount of heat, which is laborious and inconvenient for manual winding of the steel wire rope to lift it.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0028] The present utility model will be further described below with reference to the accompanying drawings:

[0029] As Figures 1 - 11 shown, a crucible furnace fixture overhead crane includes a gantry assembly 2, a trolley assembly 5 is provided on the gantry assembly 2, and further includes a guide assembly 1. A lifting assembly 4 for driving the guide assembly 1 to move up and down is provided on the trolley assembly 5, and a clamping mechanism 3 for clamping and fixing a plurality of crucible furnaces is provided at the lower end of the guide assembly 1;

[0030] In this embodiment: The clamping mechanism 3 includes a connecting seat 31. A plurality of vertically distributed active linkages 33 are hinged on the connecting seat 31. The upper ends of the active linkages 33 are hinged with hydraulic cylinders 32. The fixed ends of the hydraulic cylinders 32 are hinged to one side of the connecting seat 31. The lower ends of the active linkages 33 are hinged with a fork 35. One end of the fork 35 is hinged with a driven linkage 34. The upper end of the driven linkage 34 is hinged with a pressure rod frame 36. The position of the driven linkage 34 close to the pressure rod frame 36 is hinged with the connecting seat 31. The end of the pressure rod frame 36 away from the driven linkage 34 is provided with a plurality of T-shaped seats for supporting the crucible furnace. The active linkage 33 is rotatably connected with a limit seat 37 at the connecting seat 31. The lower end of the limit seat 37 is rotatably connected with the driven linkage 34. By pushing the upper end of the active linkage 33 to flip through the telescopic part of the hydraulic cylinder 32, the lower end of the active linkage 33 then moves in the direction opposite to its upper end, and drives the fork 35 and the driven linkage 34 to follow its movement through the lower end of the active linkage 33. At the same time, use the upper end of the driven linkage 34 to push the pressure rod frame 36 to protrude forward under the support of the limit seat 37, and let the T-shaped seat at the end of the pressure rod frame 36 press on the top of the clamped crucible furnace. Subsequently, the hydraulic cylinder 32 drives the active linkage 33 to reset, and inserts the fork 35 at the lower end of the active linkage 33 into the bottom of the crucible furnace, and then clamps a plurality of crucible furnaces simultaneously through the fork 35.

[0031] In this embodiment: The trolley assembly 2 includes a first truss 21. Two first moving vehicles 22 for driving it to move back and forth are fixed at both ends of the first truss 21. A first guardrail 23 is provided at the top of the first truss 21. A track for facilitating the movement of the trolley assembly 5 is provided at the top of the first truss 21. Use the first moving vehicles 22 on both sides of the first truss 21 to drive it to move back and forth, and then adjust the front and rear positions of the clamping mechanism 3 from the stacked crucible furnaces.

[0032] In this embodiment: The trolley assembly 5 includes a second truss 51. Two second moving vehicles 52 for moving on the track of the first truss 21 are provided at the front and rear ends of the second truss 51. A second guardrail 53 is provided at the top of the second truss 51. Use the second moving vehicles 52 on the second truss 51 to drive it to move on both sides along the track of the first truss 21, and then adjust the positions of both sides of the clamping mechanism 3 from the stacked crucible furnaces.

[0033] In this embodiment: The lower end of the guiding assembly 1 is fixed on the top of the connecting seat 31. The lifting assembly 4 is connected with the guiding assembly 1 through a steel wire rope. The guiding assembly 1 is composed of a plurality of mutually sleeved guiding tubes, and the guiding tube at the lower end of the guiding assembly 1 is provided with a runner for bypassing the steel wire rope. The guiding assembly 1 is driven to extend downward or retract upward through the steel wire rope by the lifting assembly 4.

[0034] Working principle: When in use, the first truss 21 is driven to move forward or backward by four first moving vehicles 22. When the clamping mechanism 3 approaches the position of the stacked crucible furnaces, the second moving vehicle 52 drives the second truss 51 to move on both sides along the track. At this time, the second truss 51 drives the clamping mechanism 3 to act synchronously, and then the clamping mechanism 3 is positioned corresponding to the stacked crucible furnaces;

[0035] Subsequently, the lifting assembly 4 drives the guiding assembly 1 to extend downward through the steel wire rope. When the clamping mechanism 3 is located at the position of the crucible furnace to be lifted, at the same time, the telescopic part of the hydraulic cylinder 32 pushes the upper end of the active connecting rod 33 to turn over, and the lower end of the active connecting rod 33 moves in the opposite direction and drives the row fork 35 to move away from the crucible furnace. While the row fork 35 is moving, the driven connecting rod 34 follows the active connecting rod 33 to turn over synchronously. Then the upper end of the driven connecting rod 34 pushes the pressure rod frame 36 to protrude towards the upper end of the crucible furnace under the support of the limit seat 37. At the same time, as the guiding assembly 1 extends downward, the T-shaped seat on the pressure rod frame 36 is pressed on the upper end of the crucible furnace. Then the telescopic part of the hydraulic cylinder 32 drives the upper end of the active connecting rod 33 to reset to a vertical state. At this time, the row fork 35 at the lower end of the active connecting rod 33 will be inserted into the bottoms of multiple crucible furnaces simultaneously. At the same time, the driven connecting rod 34 follows the active connecting rod 33 to act synchronously, and the driven connecting rod 34 drives the pressure rod frame 36 to press the tops of the shoveled multiple crucible furnaces tightly. Then the clamping of multiple crucible furnaces is completed simultaneously, and the lifting assembly 4 drives the guiding assembly 1 and the multiple clamped crucible furnaces to be lifted upward, and the trolley assembly 2 and the small trolley assembly 5 drive the multiple crucible furnaces to move to the corresponding positions; When it is necessary to release the multiple clamped crucible furnaces, the telescopic part of the hydraulic cylinder 32 extends and drives the active connecting rod 33 to turn over to withdraw the row fork 35 from the bottoms of the multiple crucible furnaces, and then the release of the multiple crucible furnaces is completed.

[0036] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
