Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of crane ship, especially relates to a crane ship hook sealing device. BACKGROUND
[0002] Before the towing of the grab pole type crane ship, the crane hook is generally bound and fixed to prevent the crane hook from swinging in the process of ship towing and causing adverse effects on the stability of the ship and damage to the crane, which is called hook sealing. Generally, the hook is pulled to the main deck of the ship body through the cargo winch and the reversing pulley of the crane, and the hook is bound and fixed by the lug plate, shackle and cable (as shown in Figure 1 ), but for large crane ships, the weight of the crane hook is very large, and the capacity of the cargo winch is far from enough, so the hook is pulled to the main deck of the ship body through the positioning winch and the reversing pulley on the ship, and the hook is bound and fixed by the lug plate, shackle and cable (as shown in Figure 2 ), and such operation needs the temporary removal and storage of the positioning anchor by the auxiliary ship with lifting equipment, and the positioning anchor needs to be connected to the steel wire rope of the positioning winch after the binding and fixing of the hook, which is very troublesome.

[0005] The utility model provides a crane ship hook sealing device for the binding and fixing of the hook during the towing of the crane ship, wherein two cables are bound and fixed to each hook, one end of each cable is connected with the hook, the other end is connected with the lug plate on the ship body of the crane ship, the two cables are arranged in an eight-shaped manner, and the two lug plates connected with the two cables are symmetrically arranged with the crane arm of the crane ship.
[0006] Preferably, a shackle ring is further connected to the lug plate, and the other end of the cable is connected with the shackle ring.
[0007] Preferably, the length of the cable connected with the hook closer to the ship body of the crane ship is shorter, and the distance between the two lug plates connected with the cable is shorter; the length of the cable connected with the hook farther away from the ship body of the crane ship is longer, and the distance between the two lug plates connected with the cable is longer.
[0008] Beneficial effects
[0009] The utility model provides a kind of crane ship hook sealing hook device, only the hook is connected to auxiliary ship cable, then the cable is pulled to crane ship using auxiliary ship, finally the other end of cable is connected with the lug plate on crane ship, easy to operate, without being pulled to the hull deck by winch and deflection pulley Hook, save the auxiliary time such as dismounting and installing positioning anchor, auxiliary ship also does not need to take crane equipment to hang positioning anchor, reduce operating cost.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0018] It should be noted that: similar signs and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0019] In the description of the utility model, it needs to be explained that the orientation or positional relation indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or positional relation shown in the drawings, or is the orientation or positional relation commonly placed when the utility model product is used, and is merely for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" and the like are merely used for differentiation in description, and cannot be understood as indicating or implying relative importance.
[0020] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" merely means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
[0021] In the description of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection" and "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0022] To this end, the following scheme is proposed:
[0023] Referring to Figure 3 , the utility model provides a kind of crane hook sealing hook device 100, for the binding of crane 200 when towing hook 210 is fixed, hook 210 is connected with the hoist arm 220 of crane 200 by hoisting wire rope 240, in the utility model, every hook 210 is bound and fixed two cables 110, one end of each cable 110 is connected with hook 210, and the other end is connected with the lug plate 130 on the hull 230 of crane 200, in combination Figure 4 , the two cables 110 are arranged in the shape of an eight, and the two lug plates 231 connected by the two cables 110 are symmetrically arranged with the hoist arm 220 of the crane 200.
