Abstract
Description
Technical Field
[0001] The utility model relates to large full-rotation marine floating crane equipment, and more specifically, to a shelving hook box for a four-claw main hook on a large marine floating full-rotation crane. Background Art
[0002] When the crane ship sails, the crane needs to be in the navigation anchoring state. At this time, the boom 1 is on the shelf 2, and the four-claw main hook 3 on the boom 1 needs to fall into the hook box 4 to ensure the navigation safety of the crane and the crane ship, as Figure 1 shown.
[0003] As Figure 2 shown, the four-claw main hook 3 is characterized in that the overall structure of the upper moving pulley group 31 is smaller than the overall structure of the lower four claws 32, but the fixed position 33 after falling into the hook box 4 is on the upper moving pulley group structure 31. That is, when falling into the hook box 4, the upper structure of the hook box 4 needs to avoid the large-sized four claws 32, and let the moving pulley group structure 31 fall on the support structure inside the hook box 4. The traditional hook box 4 adopts a flared guiding structure, which can be used normally when the two-claw main hook falls into the hook box, but when the four-claw main hook 3 falls into the hook box, a single claw among the four claws is likely to be shelved at the flared opening, resulting in the inability of the four-claw main hook to enter the hook box as a whole. Content of the Utility Model
[0004] Aiming at the above defects existing in the prior art, the purpose of the utility model is to provide a shelving hook box for a four-claw main hook on a large marine floating full-rotation crane, and solve the problem that the existing four-claw main hook cannot enter the hook box as a whole.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A shelving hook box for a four-claw main hook on a large marine floating full-rotation crane, comprising a pair of hook box bodies arranged in mirror symmetry, and a support structure arranged between the pair of hook box bodies;
[0007] Each of the pair of hook box bodies includes an upper structure and a lower structure, and a step for shelving the moving pulley group structure is arranged at the connection between the upper structure and the lower structure;
[0008] The step is located on the opposite surfaces of the hook box body;
[0009] The upper structure is arranged in a triangular structure;
[0010] The top angle of the triangular structure is set as an arc-shaped guiding surface;
[0011] On the opposite surfaces at the two bottom angles of the triangular structure, a guiding block is provided respectively;
[0012] The outer side of the guiding block is used to guide the four-jaw main hook, and the inner side of the guiding block is used to guide the movable pulley block structure.
[0013] Preferably, the triangular structure is an isosceles triangle.
[0014] Preferably, the slope of the outer side of the guiding block is the same as the slope of the triangular structure.
[0015] Preferably, the bottom side of the guiding block is connected to the top surface of the step.
[0016] A stowage hook box for a four-jaw main hook on a large offshore floating full-rotation crane provided by the present utility model has three guides arranged in a triangular pattern on the upper structure of the single-side hook box body, each arranged staggeredly, replacing the traditional single-side three-sided flared guide structure, enabling the four jaws of the main hook to smoothly enter the lower part of the hook box and the movable pulley block structure to enter the internal stowage place of the hook box, solving the problem of the falling hook of the four-jaw main hook.

[0022] In order to better understand the above technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.
[0023] Combined with Figures 3 to 5 shown, a stowage hook box for a four-jaw main hook on a large offshore floating full-rotation crane provided by the present utility model includes a pair of hook box bodies 10 arranged in mirror symmetry, and a support structure 11 installed between the pair of hook box bodies 10.
[0024] A pair of hook box bodies 10 each include an upper structure 12 and a lower structure 13, and a step 14 for stowing the movable pulley block structure 31 is provided at the connection between the upper structure 12 and the lower structure 13.
[0025] The step 14 is located on the opposite faces of the hook box body 10.
[0026] The upper structure 12 is arranged in an isosceles triangle structure.
[0027] The apex angle of the isosceles triangle structure is set as an arc-shaped guiding surface 15 for guiding any one of the hook claws on the four-claw main hook 3.
[0028] One guiding block 16 is arranged on each of the opposite faces at the positions of the two base angles of the isosceles triangle structure.
[0029] The outer side surface 17 of the guiding block 16 is used to continue guiding the four-claw main hook 3, and the inner side surface 18 of the guiding block 16 is used to guide the movable pulley block structure 31.
[0030] The slope of the outer side surface 17 of the guiding block 16 is consistent with the slope of the isosceles triangle structure.
[0031] The bottom side surface of the guiding block 16 is connected to the top surface of the step 14.
[0032] The shelving hook box of the present utility model replaces the traditional single-sided three-sided flared guiding structure, enabling any one of the hook claws of the four-claw hook 32 to first touch the guiding surface 15 at the top of the isosceles triangle structure and then descend along the guiding surface 15 to the guiding blocks 16 at the positions of the two base angles of the isosceles triangle structure. The outer side surface 17 of the guiding block 16 continues to guide the four-claw hook 32 to smoothly enter the lower part of the shelving hook box of the present utility model, preventing a single claw from being shelved at the step 14 position. The inner side surface 18 of the guiding block 16 then smoothly guides the movable pulley block structure 31 to be shelved on the step 14 at the connection between the upper structure 12 and the lower structure 13, thus successfully completing the action of the four-claw main hook 3 entering the shelving hook box of the present utility model.
[0033] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model and are not used to limit the present utility model. As long as within the scope of the substantial spirit of the present utility model, changes and modifications to the above-described embodiments will fall within the scope of the claims of the present utility model.
