DETAILED DESCRIPTION

[0020] The utility model includes a lifting mechanism, which is connected to a clamping body 8. The characteristic is that the clamping body 8 includes a crossbeam 10 connected to the lifting mechanism, guide mechanisms 11 cooperating with the furnace chamber are provided at both ends of the crossbeam 10, and a plurality of clamping claws are provided in the middle of the crossbeam 10.

[0021] The guide mechanisms 11 at both ends of the crossbeam 10 of the present invention precisely mate with the furnace chamber, enabling stable loading and unloading operations. The multiple opening and closing mechanisms and jaws of the clamping body 8 accommodate crucibles of varying sizes, enabling flexible and efficient loading and unloading operations, effectively reducing manual labor, improving production efficiency, and enhancing safety.

[0022] The lifting mechanism includes a lifting motor 4, which is connected to multiple drums 1 through a coupling 3 and a connecting shaft 2. A wire rope 5 is provided on the drum 1, and the end of the wire rope 5 is set as a fixed end 6. A lifting pulley 7 is provided in the middle of the wire rope 5; the lifting pulley 7 is connected to the crossbeam 10.

[0023] The lifting mechanism is driven by a lifting motor 4, which drives multiple drums 1 through a coupling 3, so that the wire rope 5 is evenly distributed with force, thereby improving the stability and load-bearing capacity of the lifting device.

[0024] There are multiple lifting pulleys 7, and connecting rods 12 are provided between the lifting pulleys 7. A sliding sleeve 13 connected to the connecting rod 12 is provided on the crossbeam 10, and an adjusting cylinder 9 is provided between the crossbeam 10 and the connecting rod 12.

[0025] The setting of the lifting pulley 7 realizes multi-point support for the crucible loading, and the connection rod 12 and the sliding sleeve 13 and the addition of the adjustment cylinder 9 make the clamp body 8 adaptable to different lifting requirements, with flexibility and applicability.

[0026] The guide mechanism 11 includes an adjustment beam 118 and a fixing frame 119. The fixing frame 119 is arranged at the end of the beam 10. A gear 112 connected to the adjustment motor 111 is provided on the fixing frame 119. A rack 116 engaged with the gear 112 is provided on the beam 10. Vertical claws 114 are provided at both ends of the adjustment beam 118, and an inclined surface 1110 is provided on the outer side of the lower end of the vertical claw 114.

[0027] The guide mechanism 11 improves the accuracy and stability of the device entering the furnace chamber. The inclined surface 1110 of the vertical claw 114 is designed to facilitate rapid positioning when entering the furnace chamber, further enhancing the convenience and accuracy of the device's operation.

[0028] A guide rail 117 is further provided on the adjustment beam 118 , a roller assembly 113 is provided between the fixing frame 119 and the guide rail 117 , and the rack 116 is also provided on the guide rail 117 .

[0029] End stops 115 corresponding to the roller assembly 113 are provided on the adjustment beam 118 at both ends of the guide rail 117 .

[0030] The clamp includes an upper arm 81 hinged to the crossbeam 10 , with an upper opening and closing cylinder 82 provided between the upper arms 81 ; a finger 85 is hingedly provided at the end of the upper arm 81 , and a lower opening and closing cylinder 84 of the finger 85 is provided on the upper arm 81 .

[0031] The jaws feature hinged upper and lower arms and are equipped with upper and lower opening and closing cylinders 82 and 84, enabling precise control of jaw opening and clamping. This structure securely grips crucibles of various shapes and sizes, offering convenient operation and high clamping reliability, further improving the efficiency of the equipment.

[0032] The upper opening and closing oil cylinder 82 is provided on the cross beam 10 , and the piston rod of the upper opening and closing oil cylinder 82 is hinged to one end of the two supporting arms 83 , and the other ends of the two supporting arms 83 are respectively connected to the two upper arms 81 .

[0033] The upper opening and closing cylinder 82 is mounted on the crossbeam 10 and is hinged to one end of the two arms 83 via a piston rod. This connection is then connected to the upper arm 81, forming an efficient system for transmitting the movement of the jaws. This design ensures operational flexibility while significantly increasing the gripping force and durability of the jaws, meeting the demands of loading and unloading heavy crucibles.

[0034] The finger 85 is arc-shaped.

[0035] The fingers 85 have an arc-shaped structure and fit closely with the cylindrical structure of the crucible, which can effectively increase the contact area, improve the clamping stability, and prevent the crucible from slipping or being damaged due to loose clamping, thereby further improving the safety and reliability of the equipment operation.

[0036] When the utility model is used, the lifting motor 4 is activated, and the drum 1 is driven to rotate through the coupling 3 and the connecting shaft 2. The drum 1 winds or releases the wire rope 5. Since one end of the wire rope 5 is a fixed end 6, the lifting pulley 7 rises or falls with the movement of the drum 1; thereby driving the crossbeam 10 to rise or fall (in the Z-axis direction).

[0037] During the descent of the beam 10, the guide mechanism 11 cooperates with the furnace chamber. Specifically, the inclined surface 1110 of the vertical claw 114 cooperates with the furnace chamber, so that the vertical claw 114 can smoothly enter the furnace chamber; the width of the vertical claw 114 is adapted to the width of the furnace chamber, the adjustment beam 118 is fixed, and the adjustment motor 111 is activated to drive the gear 112 to rotate, and the gear 112 is engaged with the rack 116. Since the adjustment beam 118 is fixed to the furnace chamber, the beam 10 will move longitudinally under the action of the gear 112 and the rack 116, thereby adjusting the longitudinal position (Y-axis direction) of the beam 10.

[0038] The adjustment cylinder 9 on the crossbeam 10 pushes the connecting rod 12 to move laterally, thereby adjusting the transverse position of the crossbeam 10 (in the X-axis direction).

[0039] After the crossbeam 10 is adjusted, the clamping jaws correspond precisely to the workpiece, the upper opening and closing cylinder 82 is actuated, driving the upper arm 81 to close or release, and the lower opening and closing cylinder 84 is actuated, driving the fingers 85 to close or release, thereby clamping or lowering the workpiece.

[0040] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
