Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a metallurgy special crane. Background Technique

[0002] During the metallurgy process, it is necessary to mechanically transport molten metal, move the molten metal to the destination, and then perform metallurgy operations. During the movement process, materials are lifted by a crane, which reduces the labor intensity of workers and provides convenience for metallurgy.

[0003] In the prior art, a metallurgy special crane with the publication number of CN210064928U adopts the following scheme: "including a transport box and a driving motor, main connecting plates are arranged on both the front and rear sides of the transport box, a secondary connecting plate is installed at the right end of the bottom plate, and a receiving hook penetrates through the interiors of both the secondary connecting plate and the main connecting plate. A limiting rod penetrates through the interior of the receiving hook, and a receiving plate is connected above the receiving hook. A connecting rope penetrates through the interior of the receiving plate, and a control box is arranged above the connecting rope. The driving motor is installed on the left side of the control box, and the output end of the driving motor is connected to a wire roller. A connecting gear is fixedly connected to the end of the wire roller, and a belt is meshed with the outer side of the connecting gear". For this metallurgy special crane, the connection between the limiting rod and the receiving hook is used to strengthen the connection between the connecting rope and the transport box, prevent the receiving hook from detaching from the transport box, and use two sets of connecting ropes to keep the transport box balanced.

[0004] However, there are still some deficiencies in the above scheme. For example, the crane in the above scheme adopts a main and auxiliary double-hook lifting structure. The main hook is used to hang and move the steel water tank, and the auxiliary hook is used to pour the steel water by tilting the steel water tank. In order to ensure that the main and auxiliary hooks do not affect each other, the above scheme needs to adopt two sets of independent lifting devices and two sets of traveling mechanisms, which increases the difficulty and cost of the crane. In view of this, the utility model proposes a metallurgy special crane. Content of the Utility Model

Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] According to the attached Figures 1-6 As shown, the embodiment of the present utility model provides a metallurgical special crane, including a cross beam 1 and a steel water tank body 2. A lifting box 3 is arranged below the cross beam 1. A transfer mechanism is arranged between the lifting box 3 and the cross beam 1. A rotation opening is formed on the right surface of the lifting box 3. A winding roller 4 is rotatably connected to the inner wall of the rotation opening. A motor 5 is fixedly installed on the left surface of the lifting box 3. The output shaft of the motor 5 extends into the interior of the lifting box 3 and is fixedly connected to the left end of the winding roller 4. Symmetrically arranged two groups of slings 6 are wound on the surface of the winding roller 4. A rope outlet opening is formed on the lower surface of the lifting box 3. A winding guiding mechanism is arranged inside the rope outlet opening. One ends of the two groups of slings 6 far from the winding roller 4 both extend to the lower surface of the lifting box 3 through the rope outlet opening and are fixedly connected to a connecting plate 7. The lower surface of the connecting plate 7 is fixedly connected to two symmetric main hooks 8 through steel ropes. Connecting frames 9 are fixedly connected to both side surfaces of the steel water tank body 2. The two main hooks 8 are respectively buckled with the two connecting frames 9. A tipping mechanism is arranged on the back of the lifting box 3.

[0027] The tipping mechanism includes an installation groove formed on the back surface of the lifting box 3. Inside the installation groove, a first hydraulic rod 10 is rotatably connected through a rotating shaft. The telescopic end of the first hydraulic rod 10 is fixedly connected to a secondary hook 11. A connecting ring 12 is fixedly connected to the back surface of the steel water tank body 2. The secondary hook 11 is buckled with the connecting ring 12. An installation plate 13 is fixedly connected to the back surface of the lifting box 3. The lower surface of the installation plate 13 is rotatably connected to a second hydraulic rod 14 through a rotating seat. The telescopic end of the second hydraulic rod 14 is rotatably connected to the surface of the first hydraulic rod 10.

[0028] The transfer mechanism includes a transfer groove formed on the lower surface of the cross beam 1. The inner walls on both sides of the transfer groove are rotatably connected with a screw rod 15. A driving device 16 for rotating the screw rod 15 is fixedly installed at the right end of the cross beam 1. A moving block 17 is threadedly connected to the surface of the screw rod 15. The lower surface of the moving block 17 is fixedly connected to the upper surface of the lifting box 3.

[0029] Two symmetric L-shaped sliding frames 18 are fixedly connected to the upper surface of the lifting box 3. Limiting sliding grooves for the L-shaped sliding frames 18 to slide are formed on both the front and back surfaces of the cross beam 1. Under the guiding action of the L-shaped sliding frames 18, the moving block 17 can drive the lifting box 3 to move left and right directionally through the rotation of the screw rod 15 for transfer operations. And through the setting of the L-shaped sliding frames 18, it can play an auxiliary load-bearing effect to prevent the gravity of the lifting box 3 from acting entirely on the moving block 17.

[0030] The winding and guiding mechanism includes an installation groove formed on the inner rear wall of the rope outlet opening. A transmission opening penetrating to the inside of the installation groove is formed on the right side surface of the lifting box 3. A transmission rod 19 is rotatably connected to the inner wall of the transmission opening. Two groups of symmetric reciprocating threads 20 are formed on the surface of the transmission rod 19 located inside the installation groove. Two symmetric threaded blocks 21 are threadedly connected to the surface of the transmission rod 19 through the two groups of reciprocating threads 20. Guide rings 22 are fixedly connected to the front surfaces of the two threaded blocks 21, and the two guide rings 22 are respectively sleeved on the surfaces of the two suspension ropes 6.

[0031] Guide sliders are arranged on the front surfaces of the guide rings 22. Guide sliding grooves for the guide sliders to slide are formed on the inner front wall of the rope outlet opening. Under the guiding action of the guide sliders, the two threaded blocks 21 can drive the two guide rings 22 to perform directional reciprocating movements respectively through the rotation of the transmission rod 19 and the reciprocating threads 20. Through the setting of the guide rings 22, the transmission rod 19 and the reciprocating threads 20, the suspension ropes 6 during winding can be guided by the moving guide rings 22 so that they are evenly wound on the surface of the winding roller 4.

[0032] One end surface of the winding roller 4 and the end surface of the transmission rod 19 extending out of the right side of the lifting box 3 are respectively fixedly connected with a driving gear 23 and a driven gear 24. The driving gear 23 and the driven gear 24 are meshed with each other. The winding roller 4 is in transmission connection with the transmission rod 19 through the driving gear 23 and the driven gear 24. Through the arrangement of the driving gear 23 and the driven gear 24, the rotation of the winding roller 4 can drive the transmission rod 19 to rotate synchronously, achieving the transmission effect.

[0033] When the metallurgical special crane of the present utility model is in use, the two main hooks 8 are connected to the connecting frames 9 on both sides of the steel water tank body 2. At this time, the motor 5 operates to drive the winding roller 4 to rotate, wind up the lifting cable 6, and perform the lifting operation on the steel water tank body 2. The rotation of the winding roller 4 drives the transmission rod 19 to rotate synchronously through the driving gear 23 and the driven gear 24. Under the rotation of the transmission rod 19 and the two sets of reciprocating threads 20, the two threaded blocks 21 respectively drive the two guide rings 22 to perform reciprocating motion in the rope outlet opening. The movement of the guide ring 22 can guide the lifting cable 6 during winding, so that it is evenly wound on the surface of the winding roller 4. When the steel water tank body 2 is lifted to an appropriate height, the driving device 16 drives the screw rod 15 to rotate, and the moving block 17 drives the lifting box 3 to move under the rotation of the screw rod 15, so as to achieve the effect of the lifting operation. When it is necessary to tilt the steel water tank body 2, the first hydraulic rod 10 and the second hydraulic rod 14 operate simultaneously. The operation and retraction of the first hydraulic rod 10 drive the rear side of the steel water tank body 2 to move upward, and drive the first hydraulic rod 10 to rotate under the retraction of the second hydraulic rod 14, so that the steel water tank body 2 can be tilted.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model, and do not limit the present utility model.
