Description

Technical Field

[0001] This invention belongs to the field of metallurgical casting technology, specifically relating to a metallurgical casting crane that can reduce swaying and its usage method. Background Technology

[0002] Metallurgical casting cranes are machines that work by longitudinally moving along the factory rails, laterally moving the trolley, and lifting the hook.

[0003] Chinese Patent Application No. 202120334708.6 discloses a metallurgical casting crane, specifically relating to the field of metallurgical casting technology. It includes a crossbeam and fixed blocks. Two sets of fixed blocks are fixedly connected to both sides of the top of the crossbeam, and a lead screw is movably connected between the fixed blocks. A limit rod is provided above the lead screw, and a servo motor is fixedly connected to one side of the lead screw. This application, by setting a first slide groove, a slide rail, a slider, and fixing bolts, addresses the limitation of traditional cranes that only have one or two hooks when transporting molten metal, which cannot ensure the balance of the molten metal during movement. To improve the balance of movement, four sets of hinged connecting plates are set at the bottom of the connecting steel plate. Four sets of hooks for lifting are set at the bottom of the connecting steel plate. The molten metal is hung on the four sets of hooks. During movement, the connecting steel plate is locked in the first slide groove inside the crossbeam, which acts as a limit. This structure achieves stable transportation of goods and reduces the frequency of shaking during transportation.

[0004] The aforementioned disclosed patents have the following problems:

[0005] 1. The spacing between the hooks cannot be adjusted during use, making it difficult to lift and move metal of different specifications. The equipment has poor applicability and is inconvenient to adjust.

[0006] 2. When the steel cable is suspended and moved, it will sway and it is difficult to stop swaying for a long time, which wastes working time, affects the production progress, and increases the operating cost.

[0007] 3. During long-term use, it is difficult to lubricate the drive device on the crossbeam, which can easily cause damage to the drive device or difficulty in moving the drive block, resulting in slowed production and wasted working resources. Summary of the Invention

[0008] To address the problems mentioned in the background section, this invention provides a metallurgical casting crane with reduced sway, featuring convenient lubrication, good anti-sway effect, and adjustable hook.

[0009] The present invention also provides a metallurgical casting crane with reduced sway and a method of using the same.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a metallurgical casting crane with reduced sway, comprising a crossbeam, a driving device being provided at the upper end of the crossbeam, a driving block being provided on the surface of the driving device, convenient lubrication components being provided at the upper ends of both sides of the driving device, anti-sway buffer components being symmetrically provided at the bottom ends of the driving blocks, a steel cable being provided inside the anti-sway buffer components, a connecting base being provided at the bottom end of the steel cable, a hook adjustment component being provided inside the connecting base, and a hook body being provided at the bottom end of the hook adjustment component.

[0011] Furthermore, in this invention, the convenient lubrication assembly includes an oil tank, an oil filling hole, a sealing plug, a limiting spring, a guide rod, a guide tube, a receiving box, and a connecting rod. An oil tank is located on the upper side of one side of the driving device, with an oil filling hole at the upper end of the oil tank. Guide rods are symmetrically arranged on one side surface of the oil tank, and a limiting spring is sleeved on the surface of the guide rod. A sealing plug is located at one end of the limiting spring. A connecting rod is located on one side of the driving block corresponding to the sealing plug, and a receiving box is located at the bottom end of the connecting rod. A guide tube is located at the bottom end of the receiving box.

[0012] Furthermore, in this invention, an observation window is provided on the side of the oil storage tank away from the sealing plug, and a flow guide block is provided at the bottom of the inside of the oil storage tank.

[0013] Furthermore, in this invention, the sealing plug has a guide hole inside corresponding to the guide rod, a flow guide plate is provided at the bottom end of the sealing plug, and a receiving plate is provided on one side of the receiving box corresponding to the flow guide plate.

[0014] Furthermore, in this invention, the hook adjustment assembly includes a slider, a bidirectional lead screw, an adjustment handle, a mounting base, and a limiting groove. The connecting base has a bidirectional lead screw inside, sliders are symmetrically arranged on the surface of the bidirectional lead screw, a mounting base is provided at the bottom of the slider, an adjustment handle is provided at one end of the bidirectional lead screw, and a limiting groove is provided at the bottom of the connecting base corresponding to the mounting base.

[0015] Furthermore, in this invention, a guide seat is provided on one side of the upper end of the connecting base, a positioning frame is provided inside the guide seat, a positioning spring is sleeved on the surface of the positioning frame, and a limit hole is provided inside the adjusting handle corresponding to the positioning frame.

[0016] Furthermore, in this invention, the anti-sway buffer assembly includes a fixed cylinder, a movable cylinder, a crash plate, a buffer spring, a damping block, and a damping sleeve. A fixed cylinder is symmetrically arranged at the bottom end of the drive block, a movable cylinder is arranged at the bottom end of the fixed cylinder, a buffer spring is symmetrically arranged inside the movable cylinder, a crash plate is arranged on one side of the buffer spring, a damping block is arranged on the middle surface of the crash plate, and a damping sleeve is arranged on the inner wall surface of the movable cylinder corresponding to the damping block.

[0017] Furthermore, in this invention, a strong magnetic block is provided on the upper surface of the fixed cylinder, a magnetic limiting plate is provided at the bottom of the inner part of the movable cylinder, and a strong magnetic ring is fixed on the bottom surface of the steel cable corresponding to the magnetic limiting plate.

[0018] Furthermore, in this invention, the method of using the metallurgical casting crane with reduced sway is as follows:

[0019] ① Adjust the spacing of the hook body according to the required metal specifications. Rotate the adjustment handle to drive the double-acting screw to rotate, while the slider moves inside the connecting base, causing the hook body at the bottom of the mounting base to move. This allows for adjustment of the spacing of the hook body, improving the applicability of the equipment. Before the hook body adjustment is complete, pull the positioning frame to compress the positioning spring. Simultaneously, the positioning frame moves along the inside of the guide seat, allowing it to be pulled out from the limiting hole inside the adjustment handle for operation. After the adjustment handle is used, release the positioning frame to reset the positioning spring. The positioning frame then re-inserts into the limiting hole to limit the adjustment handle, preventing accidental contact that could cause it to loosen. This improves the stability of the equipment and ensures the stability of the hook body after adjustment.

[0020] ② After the hook body is adjusted, the steel cable can be lowered through the drive block. The strong magnetic ring on the surface of the steel cable is attracted to the bottom of the magnetic limit plate and drives the movable cylinder to move downward. At this time, the movable cylinder separates from the strong magnetic block and slides downward along the fixed cylinder. When the steel cable sways during use, the steel cable contacts the surface of the anti-collision plate and causes the buffer spring to be compressed. The anti-collision plate is also compressed, causing the damping block to slide along the inside of the damping sleeve to suppress the elastic potential energy of the buffer spring. This ensures that the anti-collision plate can suppress the swaying of the steel cable, improve the stability of the steel cable during use, and ensure the anti-sway effect.

[0021] ③ After the hook body hangs the metal and the steel cable is retrieved and lifted, the drive block is moved by the drive device. When the drive block moves, the abutment rod on one side will abut against the side of the sealing plug, causing the sealing plug to slide along the guide rod and the limit spring to be compressed. When the sealing plug moves under force, the lubricating oil inside the oil tank can flow along the guide block to the guide plate. Then the lubricating oil on the surface of the guide plate flows to the receiving plate and finally flows into the inside of the receiving box. Then the lubricating oil flows along the guide pipe to the contact part between the drive device and the drive block for lubrication, improving the convenience of the drive block movement and ensuring the effect of the equipment.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By setting up a convenient lubrication component, the present invention allows lubricating oil to flow out and lubricate the drive device during the movement of the drive block, thereby improving the convenience of equipment lubrication, ensuring the effectiveness of equipment use, saving human resources, reducing the frequency of equipment maintenance, and ensuring that the lubricating oil flows out quickly, thus improving the lubrication effect.

[0024] 2. By setting up a hook adjustment component, the spacing of the hooks can be adjusted according to the specifications of the metal, so as to quickly hoist the metal, improve the applicability of the equipment, ensure production efficiency, and reduce the adjustment cost of the equipment.

[0025] 3. This invention, by setting up an anti-sway buffer component, uses a buffer plate to buffer and prevent swaying of the steel cable, thereby reducing the shaking of the steel cable during the metal hoisting process, improving equipment efficiency, saving production time, increasing output, and ensuring the efficiency of metallurgical work.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-5 The present invention provides the following technical solution: a metallurgical casting crane with reduced sway, comprising a crossbeam 4, a drive device 2 provided at the upper end of the crossbeam 4, a drive block 3 provided on the surface of the drive device 2, convenient lubrication components 1 provided at the upper ends of both sides of the drive device 2, anti-sway buffer components 5 symmetrically provided at the bottom ends of the drive block 3, a steel cable 6 provided inside the anti-sway buffer component 5, a connecting base 8 provided at the bottom end of the steel cable 6, a hook adjustment component 7 provided inside the connecting base 8, and a hook body 9 provided at the bottom end of the hook adjustment component 7.

[0035] Specifically, the convenient lubrication component 1 includes an oil tank 11, an oil filling hole 12, a sealing plug 13, a limiting spring 14, a guide rod 15, a flow guide tube 16, a collection box 17, and a connecting rod 18. The oil tank 11 is provided on the upper end of one side of the drive device 2. The oil filling hole 12 is provided on the upper end of the oil tank 11. The guide rod 15 is symmetrically arranged on one side surface of the oil tank 11. The limiting spring 14 is sleeved on the surface of the guide rod 15. The sealing plug 13 is provided at one end of the limiting spring 14. The connecting rod 18 is provided on one side of the drive block 3 corresponding to the sealing plug 13. The collection box 17 is provided at the bottom end of the connecting rod 18. The flow guide tube 16 is provided at the bottom end of the collection box 17.

[0036] By adopting the above technical solution, after the hook body 9 hangs up the metal and the steel cable 6 is retrieved and lifted, the drive device 2 drives the drive block 3 to move. When the drive block 3 moves, the abutment rod 18 on one side abuts against the side of the sealing plug 13, causing the sealing plug 13 to slide along the guide rod 15 and the limiting spring 14 to be compressed. When the sealing plug 13 moves under force, the lubricating oil inside the oil tank 11 can flow along the guide inclined block to the guide plate. Then the lubricating oil on the surface of the guide plate flows to the receiving plate and finally flows into the interior of the receiving box 17. Then the lubricating oil flows along the guide pipe 16 to the contact part between the drive device 2 and the drive block 3 for lubrication, improving the convenience of the drive block 3's movement and ensuring the equipment's performance.

[0037] Specifically, an observation window is provided on the side of the oil tank 11 away from the sealing plug 13, and a flow guide block is provided at the bottom of the inside of the oil tank 11.

[0038] By adopting the above technical solution, the remaining oil level can be easily checked, and the lubricating oil can be ensured to flow out quickly.

[0039] Specifically, the sealing plug 13 has a guide hole inside corresponding to the guide rod 15, a flow guide plate is provided at the bottom of the sealing plug 13, and a receiving plate is provided on one side of the receiving box 17 corresponding to the flow guide plate.

[0040] By adopting the above technical solution, the lubricating oil inside the oil tank 11 can flow along the guide block to the guide plate, and then the lubricating oil on the surface of the guide plate flows to the receiving plate and finally flows into the inside of the receiving box 17, ensuring that the lubricating oil enters the receiving box 17 stably and improving the quality of equipment use.

[0041] In this embodiment, after the hook body 9 hangs the metal and the steel cable 6 is retrieved and lifted, the drive device 2 drives the drive block 3 to move. When the drive block 3 moves, the abutment rod 18 on one side abuts against the side of the sealing plug 13, causing the sealing plug 13 to slide along the guide rod 15 and the limiting spring 14 to be compressed. When the sealing plug 13 moves under force, the lubricating oil inside the oil tank 11 can flow along the guide inclined block to the guide plate. Then the lubricating oil on the surface of the guide plate flows to the receiving plate and finally flows into the interior of the receiving box 17. Then the lubricating oil flows along the guide pipe 16 to the contact part between the drive device 2 and the drive block 3 for lubrication, improving the convenience of the drive block 3's movement and ensuring the equipment's performance.

[0042] Example 2

[0043] The difference between this embodiment and embodiment 1 is that, specifically, the hook adjustment assembly 7 includes a slider 71, a bidirectional lead screw 72, an adjustment handle 76, a mounting base 77, and a limiting groove 78. The connecting base 8 has a bidirectional lead screw 72 inside, and sliders 71 are symmetrically arranged on the surface of the bidirectional lead screw 72. The bottom end of the slider 71 is provided with a mounting base 77, and one end of the bidirectional lead screw 72 is provided with an adjustment handle 76. The bottom end of the connecting base 8 is provided with a limiting groove 78 corresponding to the mounting base 77.

[0044] By adopting the above technical solution, the spacing of the hook body 9 can be adjusted according to the required metal specifications. Rotating the adjustment handle 76 drives the bidirectional lead screw 72 to rotate, while the slider 71 moves inside the connecting base 8, causing the hook body 9 at the bottom of the mounting base 77 to move. This allows for adjustment of the spacing of the hook body 9, improving the applicability of the equipment.

[0045] Specifically, a guide seat 73 is provided on one side of the upper end of the connecting base 8, a positioning frame 75 is provided inside the guide seat 73, a positioning spring 74 is sleeved on the surface of the positioning frame 75, and a limit hole is provided inside the adjusting handle 76 corresponding to the positioning frame 75.

[0046] By adopting the above technical solution, before the hook body 9 is adjusted, the positioning frame 75 can be pulled to compress the positioning spring 74. At the same time, the positioning frame 75 moves along the inside of the guide seat 73, so that the positioning frame 75 is pulled out from the limiting hole inside the adjusting handle 76, so that the adjusting handle 76 can be operated. After the adjusting handle 76 is used, the positioning frame 75 is released to reset the positioning spring 74. At the same time, the positioning frame 75 is reinserted into the limiting hole to limit the adjusting handle 76, preventing accidental contact with the adjusting handle 76 and causing it to loosen, thereby improving the stability of the equipment and ensuring the stability of the hook body 9 after adjustment.

[0047] In this embodiment, during use: the spacing of the hook body 9 is adjusted according to the required metal specifications. Rotating the adjusting handle 76 drives the bidirectional lead screw 72 to rotate, while the slider 71 moves inside the connecting base 8, causing the hook body 9 at the bottom of the mounting base 77 to move. This allows for adjustment of the spacing of the hook body 9, improving the applicability of the equipment. Before the hook body 9 is adjusted, the positioning frame 75 can be pulled to compress the positioning spring 74. Simultaneously, the positioning frame 75 moves along the inside of the guide seat 73, causing it to be pulled out of the limiting hole inside the adjusting handle 76 for operation. After the adjusting handle 76 is used, the positioning frame 75 is released to reset the positioning spring 74. The positioning frame 75 is then reinserted into the limiting hole to limit the adjusting handle 76, preventing accidental contact that could cause it to loosen. This improves the stability of the equipment and ensures the stability of the hook body 9 after adjustment.

[0048] Example 3

[0049] The difference between this embodiment and embodiments 1 and 2 is that, specifically, the anti-sway buffer assembly 5 includes a fixed cylinder 52, a movable cylinder 53, a crash plate 54, a buffer spring 55, a damping block 56, and a damping sleeve 57. The fixed cylinder 52 is symmetrically arranged at the bottom end of the drive block 3, the movable cylinder 53 is arranged at the bottom end of the fixed cylinder 52, the buffer spring 55 is symmetrically arranged inside the movable cylinder 53, the crash plate 54 is arranged on one side of the buffer spring 55, the damping block 56 is arranged on the middle surface of the crash plate 54, and the damping sleeve 57 is arranged on the inner wall surface of the movable cylinder 53 corresponding to the damping block 56.

[0050] By adopting the above technical solution, after the hook body 9 is adjusted, the steel cable 6 can be lowered by the drive block 3. The strong magnetic ring on the surface of the steel cable 6 is attracted to the bottom end of the magnetic limiting plate 58 and drives the movable cylinder 53 to move downward. At this time, the movable cylinder 53 separates from the strong magnetic block 51 and slides downward along the fixed cylinder 52. When the steel cable 6 sways during use, the steel cable 6 contacts the surface of the anti-collision plate 54 and causes the buffer spring 55 to be compressed. The anti-collision plate 54 is compressed, causing the damping block 56 to slide along the inside of the damping sleeve 57 to suppress the elastic potential energy of the buffer spring 55. This ensures that the anti-collision plate 54 can suppress the swaying of the steel cable 6, improve the stability of the steel cable 6 during use, and ensure the anti-sway effect.

[0051] Specifically, a strong magnetic block 51 is provided on the upper surface of the fixed cylinder 52, a magnetic limiting plate 58 is provided at the bottom of the inner part of the movable cylinder 53, and a strong magnetic ring is fixed on the bottom surface of the steel cable 6 corresponding to the magnetic limiting plate 58.

[0052] By adopting the above technical solution, the steel cable 6 can be made to abut against the bottom end of the magnetic limiting plate 58 when it is being wound up, and then the movable cylinder 53 can be lifted up for storage.

[0053] In this embodiment, after the hook body 9 is adjusted, the steel cable 6 can be lowered through the drive block 3. The strong magnetic ring on the surface of the steel cable 6 is attracted to the bottom end of the magnetic limiting plate 58 and drives the movable cylinder 53 to move downward. At this time, the movable cylinder 53 separates from the strong magnetic block 51 and slides downward along the fixed cylinder 52. When the steel cable 6 sways during use, the steel cable 6 contacts the surface of the anti-collision plate 54 and causes the buffer spring 55 to be compressed. The anti-collision plate 54 is compressed, causing the damping block 56 to slide along the inside of the damping sleeve 57 to suppress the elastic potential energy of the buffer spring 55. This ensures that the anti-collision plate 54 can suppress the swaying of the steel cable 6, improve the stability of the steel cable 6 during use, and ensure the anti-sway effect.

[0054] The structure and operating principle of the drive device 2 and drive block 3 in this invention have been disclosed in a metallurgical casting crane disclosed in Chinese patent application number 202120334708.6.

[0055] The working principle and usage process of this invention: When using this invention, the spacing of the hook body 9 is adjusted according to the required metal specifications. Rotating the adjustment handle 76 drives the bidirectional lead screw 72 to rotate, while the slider 71 moves inside the connecting base 8, causing the hook body 9 at the bottom of the mounting base 77 to move. This allows for adjustment of the spacing of the hook body 9, improving the applicability of the equipment. Before the adjustment of the hook body 9 is completed, the positioning frame 75 can be pulled to compress the positioning spring 74. At the same time, the positioning frame 75 moves along the inside of the guide seat 73, allowing the positioning frame 75 to be pulled out from the limiting hole inside the adjustment handle 76 for operation. After the adjustment handle 76 is used, the positioning frame 75 is released to reset the positioning spring 74. Simultaneously, the positioning frame 75 is reinserted into the limiting hole to limit the adjustment handle 76, preventing accidental contact that could cause it to loosen, thus improving the stability of the equipment and ensuring the stability of the hook body 9 after adjustment.

[0056] After the hook body 9 is adjusted, the steel cable 6 can be lowered by the drive block 3. The strong magnetic ring on the surface of the steel cable 6 is attracted to the bottom of the magnetic limit plate 58 and drives the movable cylinder 53 to move downward. At this time, the movable cylinder 53 separates from the strong magnetic block 51 and slides downward along the fixed cylinder 52. When the steel cable 6 sways during use, the steel cable 6 contacts the surface of the anti-collision plate 54 and causes the buffer spring 55 to be compressed. The anti-collision plate 54 is compressed and causes the damping block 56 to slide along the inside of the damping sleeve 57 to suppress the elastic potential energy of the buffer spring 55. This ensures that the anti-collision plate 54 can suppress the swaying of the steel cable 6, improve the stability of the steel cable 6 during use, and ensure the anti-sway effect.

[0057] After the hook body 9 hangs the metal and the steel cable 6 is retrieved and lifted, the drive device 2 drives the drive block 3 to move. When the drive block 3 moves, the abutment rod 18 on one side abuts against the side of the sealing plug 13, causing the sealing plug 13 to slide along the guide rod 15 and the limiting spring 14 to be compressed. When the sealing plug 13 moves under force, the lubricating oil inside the oil tank 11 can flow along the guide inclined block to the guide plate. Then the lubricating oil on the surface of the guide plate flows to the receiving plate and finally flows into the interior of the receiving box 17. Then the lubricating oil flows along the guide pipe 16 to the contact part between the drive device 2 and the drive block 3 for lubrication, improving the convenience of the drive block 3's movement and ensuring the equipment's performance.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Rotate the adjustment handle to drive the double-acting screw to rotate, while the slider moves inside the connecting base, causing the hook body at the bottom of the mounting base to move. This allows for adjustment of the spacing of the hook body, improving the applicability of the equipment. Before the hook body adjustment is complete, pull the positioning frame to compress the positioning spring. Simultaneously, the positioning frame moves along the inside of the guide seat, allowing it to be pulled out from the limiting hole inside the adjustment handle for operation. After the adjustment handle is used, release the positioning frame to reset the positioning spring. The positioning frame then re-inserts into the limiting hole to limit the adjustment handle, preventing accidental contact that could cause it to loosen.
