[0002] In recent years, my country's port trade has flourished, and the throughput capacity of general cargo terminals has continued to increase. To improve the efficiency of in-deck operations, domestic general cargo terminals mainly use in-deck operating machinery such as forklifts, tire cranes, and excavators. However, forklifts have a small operating range, low lifting height, and limited cargo types; tire cranes cannot lift and travel, and require a large amount of auxiliary work; excavators have a small operating radius and lifting height, and low lifting performance. Due to the small working space and low height under the cabin, these machines have certain operational limitations.

[0003] Currently, conventional lower-deck equipment is a crawler crane with a two-section telescopic boom that can only perform pitching and extension of the main boom, making it impractical in the narrow space of a ship's cabin. Furthermore, hook-only operations alone cannot meet the needs of stacking at the highest level. Summary of the Invention

[0032] The guide mechanism includes two sets of sliders, one set of sliders is installed at the front lower and front side of the two-section arm 5, and the other set of sliders is installed at the rear upper and rear lower of the three-section arm 7. The two sets of sliders cooperate to play a guiding role during the extension and contraction of the three-section arm 7.

[0033] Specific implementation method six: combination Figures 1 to 3 To explain this embodiment, the vertical rotation mechanism described in this embodiment includes a pull plate 8, a pressure plate 11, a lever cylinder 13, a first fixed shaft 16 and a second fixed shaft 15. The upper portion of the rear end of the lever frame 9 is hinged to the upper portion of the front end of the three-section arm 7 via the first fixed shaft 16. The cylinder end of the lever cylinder 13 is hinged to the front end of the three-section arm 7. The rod end of the lever cylinder 13 is hinged to one end of the pull plate 8 and one end of the pressure plate 11. The other end of the pull plate 8 is hinged to the upper portion of the front end of the three-section arm 7 via the second fixed shaft 15. The other end of the pressure plate 11 is hinged to the lower portion of the rear end of the lever frame 9. Other components and connection methods are the same as those of the first embodiment.

[0034] When the lifting lever cylinder 13 is extended, under the action of the pulling plate 8 and the pressing plate 11, the lifting lever 10 will rotate clockwise around the first fixed axis 16 along with the lifting lever frame 9; when the lifting lever cylinder 13 is retracted, under the action of the pulling plate 8 and the pressing plate 11, the lifting lever 10 will rotate counterclockwise around the first fixed axis 16 along with the lifting lever frame 9, thus completing the swinging process of the lifting lever 10 in the vertical plane.

Other components and connection methods are the same as those of the sixth embodiment.

[0036] Specific implementation method eight: combination Figures 1 to 3 In this embodiment, both the first and second fixed shafts 16, 15 have fixed plates welded to one end, rigidly connected to the outer wall of the three-section arm 7. The remaining components and connection methods are identical to those in the seventh embodiment. The other ends of the first and second fixed shafts 16, 15 are secured with nuts. This design facilitates installation and removal of the first and second fixed shafts 16, 15.

[0037] The rear end face of the described lifting bar frame 9 is tilted to the front side from top to bottom. As designed to prevent the lifting bar frame 9 from causing interference during rotation.

A notch 21 is provided on the front end surface of the lifting lever frame 9 along the width direction. The rear end of the lifting lever 10 is inserted into the notch 21 and is hinged to the lifting lever frame 9 via the kingpin 20. The cylinder end of the swing cylinder 18 is hinged to one side inside the lifting lever frame 9 via the first pin 17, and the rod end of the swing cylinder 18 is hinged to one side of the rear end of the lifting lever 10 via the second pin 19. Other components and connection methods are the same as those in the first embodiment.

[0039] When the swing cylinder 18 is extended, the lifting lever 10 will rotate clockwise around the main pin 20; when the swing cylinder 18 is retracted, the lifting lever 10 will rotate counterclockwise around the main pin 20, thus completing the process of the lifting lever 10 swinging in the horizontal plane.

[0040] When the lifting cylinder 13 and the swing cylinder 18 are extended and retracted simultaneously or alternately, the compound action of the lifting cylinder 10 is completed.

[0041] The width of the notch 21 in the horizontal direction is greater than the width of the rear end of the lever 10. This design prevents interference during the rotation of the lever 10.

[0042] The lifting bar 10 is a hollow structure. Such a design can reduce the deadweight of the lifting bar 10 on the one hand and strengthen the strength of the lifting bar 10 on the other hand.

[0043] One side of the rear end of the lifting lever 10 is fixedly connected with a fixed ear plate 22, and the rod end of the swing oil cylinder 18 is hinged to the fixed ear plate 22 through a second pin 19. Such a design facilitates the hinge connection between the lifting lever 10 and the swing oil cylinder 18.

[0044] The bottom of the described lifting bar 10 front ends is fixed with a group of connecting lugs 23. Such design can be used for the hoisting or auxiliary hoisting and stacking of goods.

[0045] Specific implementation method ten: Combination Figures 1 to 3 To illustrate this embodiment, the kingpin 20 of this embodiment is vertically arranged on the inner side of the front end of the lifting lever frame 9 and is rotatably connected to the lifting lever frame 9. The rear end of the lifting lever 10 is sleeved on the kingpin 20 and is rigidly connected to the kingpin 20. Other components and connection methods are the same as those of the ninth embodiment.

[0046] In this embodiment, the hook 12 is hinged to the arm head of the three-section boom 7 via a pin. When the cargo in the hold is diverse and the lift bar 10 is not well suited to the prevailing working conditions, the hook 12 can be used. If the lift bar 10 interferes with stacking, the first fixed shaft 16 can be removed, and the lift bar frame 9, along with the lift bar 10 and pressure plate 11, can be removed simultaneously, allowing the hook 12 to operate solely.
