Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a ship boom structure. Background Technology

[0002] A ship's boom is the core extension structure of the lifting equipment used for loading and unloading cargo on a ship, and is an important component of marine cranes (such as gantry cranes).

[0003] Existing ship cranes have complex structures and unreasonable designs. During use, the stress on different parts of the wire rope varies, but existing ship cranes cannot mitigate this, resulting in significant differences in stress levels at different locations on the wire rope. Over time, this easily leads to wire rope damage and shortens its lifespan. In addition, the end of the wire rope closest to the object being lifted usually sways more, making it difficult to maintain high stability. Therefore, the inventors have improved the structure of ship cranes. Utility Model Content

[0004] The purpose of this utility model is to provide a ship crane structure. This ship crane structure has the advantages of simple structure, reasonable design, and the ability to adjust the pressure on different parts of the wire rope according to the different pressure emphasis positions. It can relieve the pressure on the parts with high pressure, reduce the damage to the wire rope, extend its service life, and limit the end of the wire rope close to the object to be lifted to a certain extent, so as to avoid large-scale swaying and improve the stability of the wire rope. It solves the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ship crane structure, which includes a base and a turntable mounted on the base.

One end of the steel wire rope is wound around the storage cylinder, and the other end passes around the head pulley and is provided on the hook. A pressure adjustment mechanism is provided between the head pulley and the hook.

[0006] The pressure regulating mechanism includes a support, on which a first hydraulic cylinder and a second hydraulic cylinder are fixed. The first hydraulic cylinder is located above the second hydraulic cylinder, and the output end of the first hydraulic cylinder is connected to a first mounting base. A proximal pulley is mounted on the first mounting base. The output end of the second hydraulic cylinder is connected to a push plate, on which a second mounting base is fixed. A distal pulley is mounted on the second mounting base.

[0008] Preferably, the wire rope includes a distal end and a wire rope storage end and a proximal end respectively disposed at both ends of the distal end. The end of the wire rope storage end closest to the distal end is disposed on the head pulley. Both the distal end and the proximal end of the wire rope are vertically arranged, and the distal end of the wire rope is in contact with the distal pulley. The end of the proximal end of the wire rope away from the distal end is fixed to the main boom, and the proximal end of the wire rope is in contact with the proximal pulley.

[0012] Preferably, a cylinder seat is fixed to the lower end face of the support, and the second hydraulic cylinder is fixed to the cylinder seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a ship crane structure, which includes a base and a turntable mounted on the base. A storage cylinder and a transfer wheel located on one side of the storage cylinder are mounted on the turntable. A wire rope is provided on the storage cylinder. A head pulley and a hook located below the head pulley are provided at the end of the transfer wheel away from the storage cylinder. One end of the wire rope is wound around the storage cylinder, and the other end is wrapped around the head pulley and set on the hook. A pressure regulating mechanism is provided between the head pulley and the hook. The wire rope includes a distal end and a storage end and a proximal end respectively provided at both ends of the distal end. The end of the storage end near the distal end is set on the head pulley. The pressure regulating mechanism includes a support, on which a first hydraulic cylinder and a second hydraulic cylinder are fixed. The output end of the first hydraulic cylinder is connected to... The device has a first mounting base, on which a proximal pulley is mounted, connecting to the near end of the wire rope. A push plate is connected to the output end of a second hydraulic cylinder, on which a second mounting base is fixed. A distal pulley, connecting to the far end of the wire rope, is mounted on the second mounting base. When the pressure on the near end of the wire rope is greater, the first hydraulic cylinder drives the proximal pulley to work, pushing the near end of the wire rope away from the main boom, thus reducing the pressure on the near end. When the pressure on the far end of the wire rope is greater, the far end is pushed away from the main boom, further reducing the pressure on the far end. Therefore, the pressure adjustment mechanism can adjust the pressure on different parts of the wire rope according to the different pressure emphasis positions, relieving pressure on areas with higher pressure, reducing damage to the wire rope, extending its service life, and demonstrating strong practicality.

[0015] 2. The pressure adjustment mechanism in this utility model is directly fixed to the main boom. The overall structure is simple, the design is reasonable, and it occupies less space. It will not protrude excessively from the surface of the ship's boom structure, nor will it affect the functionality of the ship's boom structure. Therefore, it will not conflict with other external structures during use and is suitable for widespread use.

[0016] 3. In this utility model, the near-end pulley is close to the near end of the wire rope, and the far-end pulley is close to the far end of the wire rope. Therefore, the positions of the near end and the far end of the wire rope can be limited to a certain extent, avoiding large-scale swaying and thus improving the stability of the wire rope.

A pressure plate is provided between the head pulley 6 and the hook 7. The force adjustment mechanism 8 is included. In addition, the ship's boom structure also includes a main boom 9 installed on the turntable 2. A first hydraulic cylinder 10 and a second hydraulic cylinder 11 located above the first hydraulic cylinder 10 are arranged between the turntable 2 and the main boom 9.

The connection method between the turntable 2 and the main boom 9 and the installation method of the first hydraulic cylinder 10 and the second hydraulic cylinder 11 are all existing technologies. In addition, the working principle of the ship's boom structure is also existing technology, and will not be described in detail here.

[0027] Please see Figure 2 The wire rope 5 includes a wire rope distal end 52 and a wire rope storage end 51 and a wire rope proximal end 53 respectively disposed at both ends of the wire rope distal end 52. The end of the wire rope storage end 51 closest to the wire rope distal end 52 is disposed on the head pulley 6. Both the wire rope distal end 52 and the wire rope proximal end 53 are vertically disposed. The end of the wire rope proximal end 53 furthest from the wire rope distal end 52 is fixed to the main boom 9.

[0028] Please see Figure 3The hook 7 includes a receiving block 71, on which a first connecting shaft 72 and a second connecting shaft 73 located below the first connecting shaft 72 are installed. The end of the wire rope 52 near the proximal end 53 passes around the first connecting shaft 72. A main hook body 74 is provided below the second connecting shaft 73. The main hook body 74 includes a support head 741 fixed to the second connecting shaft 73. An outer receiving hook 742 and an inner receiving hook 743 are respectively provided at both ends of the support head 741. The outer receiving hook 742 is located below the far end 52 of the wire rope, and the inner receiving hook 743 is located below the proximal end 53 of the wire rope.

[0029] Please see Figure 4 The pressure regulating mechanism 8 includes a support 81, on which a first hydraulic cylinder 82 is fixed. The output end of the first hydraulic cylinder 82 is connected to a first mounting base 83. A proximal pulley 84 that contacts and connects with the proximal end 53 of the wire rope is mounted on the first mounting base 83.

[0030] Please see Figure 5 A cylinder seat 85 is fixed to the lower end face of the support 81, and a second hydraulic cylinder 86 is fixed to the cylinder seat 85. A first hydraulic cylinder 82 is located above the second hydraulic cylinder 86. A push plate 87 is connected to the output end of the second hydraulic cylinder 86. A second mounting seat 88 is fixed to the push plate 87. A distal pulley 89 that contacts and connects with the distal end 52 of the wire rope is installed on the second mounting seat 88. The proximal end 53 of the wire rope is located between the proximal pulley 84 and the distal pulley 89. The distal end 52 of the wire rope is located at the end of the distal pulley 89 that is away from the proximal pulley 84. Therefore, the proximal pulley 84 and the distal pulley 89 can limit the proximal end 53 of the wire rope and prevent the proximal end 53 of the wire rope from shaking significantly. The distal pulley 89 can also reduce the shaking of the distal end 52 of the wire rope to a certain extent.

[0031] Working principle: Please refer to the following again. Figures 1 to 5 In the operation of this utility model, the object to be hoisted is hung on the outer receiving hook 742 and the inner receiving hook 743. If the pressure on the outer receiving hook 742 is greater than the pressure on the inner receiving hook 743, the second hydraulic cylinder 86 is driven to run, causing the distal pulley 89 to contact the distal end 52 of the wire rope and push the distal end 52 of the wire rope a distance away from the main boom 9, thereby reducing the pressure on the distal end 52 of the wire rope and protecting it. If the pressure on the inner receiving hook 743 is greater than the pressure on the outer receiving hook 742, the first hydraulic cylinder 82 is driven to run, causing the proximal pulley 84 to contact the proximal end 53 of the wire rope and push the proximal end 53 of the wire rope a distance away from the main boom 9, thereby reducing the pressure on the proximal end 53 of the wire rope and protecting it. This makes the pressure difference between the distal end 52 and the proximal end 53 of the wire rope smaller, which is beneficial to protecting the wire rope 5.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
