Description

Technical Field

[0001] This invention relates to the technical field of lifting equipment, and in particular to a lifting device for unpacking containers. Background Technology

[0002] The greatest success of the container lies in the standardization of its products and the resulting comprehensive transportation system. It enables the standardization of a massive container weighing tens of tons, and on this basis, gradually realizes a global logistics system that integrates ships, ports, shipping routes, highways, transit stations, bridges, tunnels, and multimodal transport.

[0003] When unpacking containers, cranes are used. Cranes work in conjunction with lifting equipment to lift the disassembled containers. Currently, the lifting device on the crane starts the first motor to drive the storage shaft to rotate. The rotation of the storage shaft is used to retract and extend the wire rope to achieve the lifting operation of the crane.

[0004] However, cranes are generally equipped with a lifting device. When the wire rope on the turntable device is damaged and needs to be replaced, or when the lifting device is damaged and needs to be repaired or replaced, the corresponding crane cannot lift the load smoothly, which may cause delays in the construction period. Therefore, there are areas for improvement. Summary of the Invention

[0019] In summary, the present invention has the following beneficial technical effects:

[0020] 1. This invention features a first lifting structure within the mounting housing and second lifting structures on both the left and right sides of the mounting housing. When the second storage shaft within the mounting housing is damaged and requires further operation, the second lifting structure can be activated to carry out construction work, ensuring the normal operation of the crane and avoiding delays in the construction period. Furthermore, the second lifting structure is equipped with a storage shell, a shell cover, and a rain cover. When the second lifting structure is not in use, the shell cover can be tightly closed onto the storage shell to store the wire rope and the first storage shaft on the second lifting structure, reducing the risk of corrosion and damage and extending the service life of the second lifting structure. At the same time, the second lifting structure can be activated while the first lifting structure is in use, thereby improving lifting efficiency.

[0021] 2. This invention features a push-opening structure and a drive structure within the connecting seat. The cover is mounted on the push-opening structure via a rotating structure. When using the second lifting structure, the drive structure and the push-opening structure are used to push open the steel wire ropes on the two sets of second lifting structures, avoiding work interference between the two second lifting structures and between the second lifting structure and the first lifting structure due to excessively close distance. Simultaneously, when the push-opening structure retracts the two sets of second lifting structures, it can automatically squeeze and lift the cover plate, automatically sealing the cover plate onto the storage shell, making operation more labor-saving and convenient.

[0022] 3. The present invention provides a support and limiting structure between the shell cover and the support base. When the shell cover is rotated down to the support base, the gravity generated on the wire rope during the lifting process pulls the support column on the shell cover to be clamped and limited between the two spherical blocks in the support groove. The support base provides support and limiting for the shell cover, increasing structural stability and preventing the shell cover from being pulled up when the wire rope is wound up for lifting.

[0023] 4. This invention features a reciprocating traction structure on the mounting housing, which automatically and evenly winds the wire rope onto the second winding shaft during the winding process. The reciprocating traction structure also includes a support structure, a cleaning structure, and a transmission structure, providing support for the wire rope during lifting, reducing wear. Simultaneously, it automatically drives the cleaning structure to remove small grains of sand adhering to the wire rope, preventing the wire rope with sand adhering to it from being directly wound onto the second winding shaft, thus avoiding a shortened service life.

[0036] The following is in conjunction with the appendix Figures 1-11 The present invention will be described in further detail below.

[0037] This invention discloses a container unpacking hoisting device, including a connecting seat 1 and a mounting shell 2. A first hoisting structure is provided inside the mounting shell 2, and a second hoisting structure is installed on both the left and right sides of the mounting shell 2. A reciprocating traction structure is provided at the front of the mounting shell 2, and a driving structure is provided in the middle of the connecting seat 1.

[0038] The second lifting structure includes a storage shell 3 installed on the left and right sides of the connecting seat 1. A rain cover 9 is installed on the edge of the storage shell 3 away from the mounting shell 2. The side of the storage shell 3 away from the mounting shell 2 is inclined. A pressing edge 10 is provided on the lower edge of the side of the storage shell 3 away from the mounting shell 2. A motor box 4 is installed in the middle of the rear side of each storage shell 3. A first storage shaft 5 is installed on one end of the output shaft of the third motor inside the motor box 4. A steel wire rope is wound on the first storage shaft 5. A push-opening structure is provided at both ends inside the connecting seat 1. A shell cover 6 is provided on the push-opening structure.

[0039] A first opening 7 is provided on the side of the cover 6 away from the mounting shell 2. Two first pulleys 8 are movably installed in the first opening 7. The steel wire rope on the first storage shaft 5 passes between the two first pulleys 8. In the event of damage to the first lifting structure, in order not to delay the construction period, the third motor in the motor box 4 of the second lifting structure can be started to drive the first storage shaft 5 to rotate, thereby assisting in the lifting work, ensuring the smooth progress of the work, and reducing the problem of construction period delay.

[0040] See Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The push-open structure includes movable plates 11 inserted into the two ends of the connecting seat 1. Support rods 12 are connected to the corners of the two movable plates 11 that are away from each other on one side. The end of each set of support rods 12 that is away from the movable plates 11 is connected to the support seat 13. The cover 6 is set on the support seat 13 through a rotating structure.

[0041] The drive structure includes two first fixing plates 16 connected to the lower inner wall of the connecting seat 1 near the middle. A bidirectional screw 18 rotates through the two first fixing plates 16. The left and right threads of the bidirectional screw 18 are in opposite directions. The two ends of the bidirectional screw 18 pass through the threaded grooves in the middle of the two moving plates 11 respectively. A second gear 17 is fixedly sleeved on the middle of the bidirectional screw 18. A second motor 14 is installed on the lower inner wall of the connecting seat 1 near the first fixing plates 16. The output shaft of the second motor 14 is fixedly sleeved with the first gear 17. 5. The first gear 15 and the second gear 17 are meshed together. When the second motor 14 is started to drive the bidirectional screw 18 to rotate, the two moving plates 11 move synchronously in opposite directions. This opens the cover 6 on the storage shell 3 and increases the lifting distance between the two second lifting structures, reducing mutual interference during the lifting process. Furthermore, since one side of the storage shell 3 is inclined, the cover 6 can rotate to a horizontal state under its own weight when the cover 6 is pushed open, and the cover 6 is supported on the support base 13.

[0042] The rotating structure includes two second fixed plates 19 connected to the support base 13 at the front and rear edges near the support rod 12. A first rotating shaft 20 is rotatably passed through the top of the two second fixed plates 19. Limiting sleeves 21 are fixedly fitted on both sides of the shell cover 6 on the first rotating shaft 20. The shell cover 6 is fitted on the first rotating shaft 20. A through groove 22 is opened on the shell cover 6 for the first rotating shaft 20 to pass through. A second opening 23 is opened in the middle of the side of the shell cover 6 near the mounting shell 2. A second rotating shaft 24 is rotatably passed through the shell cover 6 at the position of the second opening 23. A compression cylinder 25 is movably fitted on the second rotating shaft 24. A support limiting structure is provided between the bottom of the shell cover 6 and the support base 13. When the two shell covers 6 move synchronously toward the position near the storage shell 3, the shell cover 6 is pressed against the compression edge 10 of the storage shell 3, so that the shell cover 6 can automatically rotate up and stick to the storage shell 3, thereby storing the first storage shaft 5 and the wire rope, reducing the problem of rust and affecting its service life.

[0043] The support and limiting structure includes two first vertical plates 26 connected to the bottom of the shell cover 6. A support column 27 is fixedly connected between the two first vertical plates 26. A support groove 28 is provided on the support base 13 for supporting the support column 27. Slots 29 are provided on both sides of the groove wall of the support groove 28. A plug 30 is movably inserted into each of the two slots 29. A spring is connected between one end of the plug 30 and the inner end of the slot 29. A ball block 31 is installed on the other end of the plug 30 and abuts against the support column. 27. When the cover 6 rotates down onto the support seat 13, and during the lifting process, the tension generated by the weight on the wire rope is used to pull the support column 27 on the cover 6 through the first pulley 8 to squeeze the two spherical blocks 31 to both sides, so that the support column 27 is supported in the support groove 28, increasing the support stability of the cover 6. In addition, the spring force is used to reset the spherical blocks 31, which can limit the cover 6 on the support seat 13 and prevent the cover 6 from rotating during the lifting process.

[0044] The first lifting structure includes a second storage shaft 32 rotatably connected to the inner walls of both sides of the mounting shell 2. A third gear 33 is fixedly sleeved at one end of the second storage shaft 32. A first motor 34 is installed on the rear inner wall of the mounting shell 2. A fourth gear 35 is fixedly sleeved on the output shaft of the first motor 34. The fourth gear 35 and the third gear 33 are meshed together. A steel wire rope is wound on the second storage shaft 32. When the first motor 34 is started to drive the second storage shaft 32 to rotate, the steel wire rope can be wound up inside the mounting shell 2 to carry out lifting work.

[0045] See Figures 1-5The reciprocating traction structure includes fixing strips 36 connected to the two sides of the front of the mounting shell 2. A reciprocating lead screw 37 rotatably passes through the two fixing strips 36 near the second receiving shaft 32. A limiting rod 40 is fixedly passed through the two fixing strips 36 below the reciprocating lead screw 37. A lead screw sleeve 41 is fitted onto the limiting rod 40 and the reciprocating lead screw 37. A reciprocating frame 42 is installed below the lead screw sleeve 41. U-shaped rods 43 are connected to the four inner walls of the reciprocating frame 42. A movable cylinder 44 is rotatably fitted onto each U-shaped rod 43. One end of the reciprocating lead screw 37 is connected to the second receiving shaft 32. The other end is fitted with a pulley 39, and a belt 38 is fitted on the two pulleys 39. A support structure is provided at the front end of the two fixing bars 36. When the first motor 34 is started, it drives the second storage shaft 32 to rotate. During the winding and lifting process, the belt 38 and pulley 39 drive the reciprocating screw 37 to rotate. The screw sleeve 41 drives the reciprocating frame 42 passing through the wire rope to move back and forth, so that the wire rope can be evenly wound onto the second storage shaft 32. Furthermore, by utilizing the rotation of the movable cylinder 44 on the U-shaped rod 43, the static friction generated between it and the wire rope can be reduced, thereby reducing wear.

[0046] The support structure includes a horizontal plate 45 connected between the front ends of two fixed bars 36. A rotating column 47 rotates through the middle of the horizontal plate 45. A turntable 46 is installed on the top of the rotating column 47. Two second vertical plates 48 are connected to the top of the turntable 46. Two third rotating shafts 49 rotate through the two second vertical plates 48. A second pulley 50 is fixedly sleeved in the middle of each of the two third rotating shafts 49. The steel wire rope wound on the second storage shaft 32 passes through the two second pulleys 50. A cleaning structure is provided in the middle of the two second vertical plates 48 near the mounting shell 2. A transmission structure is provided between the cleaning structure and the third rotating shafts 49 below. The two second pulleys 50 can support the steel wire rope wound on the second storage shaft 32. At the same time, the rotation of the second pulleys 50, combined with the rotation of the rotating column 47 driven by the steel wire rope during uniform winding, can reduce the wear of the steel wire rope during winding and extend the service life of the steel wire rope.

[0047] The cleaning structure includes two fourth fixing plates 51 connected to the middle of the rear side of two second vertical plates 48. The rear end of each of the two fourth fixing plates 51 is provided with a rotating groove 52. A rotating sleeve 53 rotates through the two rotating grooves 52. A cleaning sleeve 54 is installed on the rear end of the rotating sleeve 53. Brush bristles 55 are provided on the inner wall of the cleaning sleeve 54. A seventh gear 63 is fixedly sleeved in the middle of the outer side of the rotating sleeve 53.

[0048] The transmission structure includes an eighth gear 64 sleeved at the right end of the lower third rotating shaft 49. A fourth rotating shaft 56 is rotatably connected to the right side of the second vertical plate 48 above the eighth gear 64. A fifth gear 57 is fixedly sleeved on the fourth rotating shaft 56, and the fifth gear 57 is meshed with the eighth gear 64. A first bevel gear 58 is fixedly sleeved on the end of the fourth rotating shaft 56 away from the second vertical plate 48. A second bevel gear 59 is meshed with the first bevel gear 58. The second bevel gear 59 is fixedly sleeved on one end of the fifth rotating shaft 61. A third fixed plate 60 is rotatably sleeved on the fifth rotating shaft 61. One end of the third fixing plate 60 is connected to the fourth fixing plate 51 on the right side. The sixth gear 62 is fixedly sleeved on the rear end of the fifth rotating shaft 61. The sixth gear 62 is meshed with the seventh gear 63. During the winding process, the wire rope will drive the second pulley 50 and the third rotating shaft 49 below to rotate. The fifth rotating shaft 61 will be driven to rotate through the eighth gear 64, the fifth gear 57, the first bevel gear 58 and the second bevel gear 59. In addition, the sixth gear 62 and the seventh gear 63 will drive the cleaning sleeve 54 and the brush bristles 55 to rotate as a whole, so as to better clean the small stones adhering to the wire rope.

[0049] The implementation principle of a container unpacking lifting device according to an embodiment of the present invention is as follows: During lifting operations, firstly, the first motor 34 inside the mounting shell 2 is started to drive the second receiving shaft 32 to rotate, thereby winding the wire rope, and then lifting the heavy object on the construction site. During the rotation of the second receiving shaft 32, the reciprocating screw 37 is driven to rotate through the pulley 39 and the belt 38. The screw sleeve 41 drives the wire rope in the reciprocating frame 42 to move back and forth, which can evenly wind the wire rope onto the second receiving shaft 32, and the wire rope passes through two second pulleys 5. 0. By utilizing the rotation of the second pulley 50, the static friction generated between it and the wire rope can be reduced. Simultaneously, the rotation of the lower second pulley 50 drives the lower third rotating shaft 49 to rotate. This, through the eighth gear 64, fifth gear 57, first bevel gear 58, and second bevel gear 59, drives the fifth rotating shaft 61 to rotate on the third fixed plate 60. The sixth gear 62 and seventh gear 63 then drive the cleaning sleeve 54 and brush bristles 55 to rotate as a whole, thereby cleaning small stones adhering to the wire rope. When the first motor 34, second storage shaft 32, or steel... When the wire rope is damaged, in order not to delay the construction period, the second motor 14 in the connecting seat 1 can be started. The first gear 15 and the second gear 17 drive the bidirectional screw 18 to rotate. The two moving plates 11 move synchronously on both sides of the connecting seat 1, driving the support seat 13 at one end of the support rod 12. When the cover 6 detaches from the storage shell 3, under its own weight, the cover 6 rotates around the first rotating shaft 20 and supports itself on the support seat 13. The movement of the cover 6 increases the lifting distance between the two second lifting structures, preventing damage during lifting. During the process, mutual interference occurs. When a heavy object is hung on one end of the wire rope on the first receiving shaft 5, the tension of the wire rope pulls the support column 27 under the cover 6 down into the support groove 28 on the support seat 13, increasing the stability of the cover 6. Finally, the third motor in the motor box 4 can be started to drive the first receiving shaft 5 to rotate, causing the wire rope to move between the two second pulleys 50, which plays an auxiliary role in lifting, ensuring the smooth progress of the lifting work, and reducing the problem of construction delays caused by damage to the winch.

[0050] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
