Description

Technical Field

[0001] This utility model belongs to the field of port construction machinery, specifically relating to an adjustable sea lashing rod suitable for port cranes, quay cranes, container cranes, and large ship unloaders. Background Technology

[0002] As port construction expands, port equipment capacity also increases, leading to a growing demand for ultra-large lifting capacity gantry cranes, quay cranes, and large ship unloaders.

[0003] The previous methods of transporting port machinery and equipment in loose parts by ship and lashing large items can no longer meet the current requirements for equipment transportation. From domestic river ports to overseas ocean ports, choosing a safe and fast transportation method has become a crucial aspect for every port company.

[0004] As large-scale port equipment, its inland waterway transportation and ocean shipping must both consider the complexity of transportation conditions and the impact of transport vessels on the equipment. To ensure the safety and stability of the equipment during transportation, a complete transportation lashing plan is required for different products. By using reasonable methods to secure the equipment to the hull, it is possible to ensure smooth transportation to the user's dock and rapid installation and use on shore.

[0005] Current sea lashing rods typically use perforated lugs at the ends, with lugs mounted on the ship's deck. These lugs are hinged to the lug holes using pins to secure large offshore or port machinery equipment to the hull. Due to the varying structures of large offshore or port machinery, the relative spatial positions of the sea lashing lugs and the deck-mounted sea lashing lugs are constantly changing during the sea lashing process. For example, the entire weight of a ship unloader rests on the lower crossbeam of the gantry. This lower crossbeam consists of multiple sets of balance beams, trolleys, and wheel sets. Because the wheel sets roll, and they need to be rolled onto the ship, they cannot be removed. Therefore, the freedom of the lower crossbeam must be controlled to ensure the equipment is integrated with the ship's structure. Current sea lashing rod structures only provide a rigid, fixed connection to the equipment without any adjustable space. This makes it impossible to adjust the distance between the ends of the sea lashing rod and the equipment or ship's deck. There are gaps after welding, and the equipment is only usable once, cannot be reused, is costly, and is not environmentally friendly. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides an adjustable sea tying rod, which can conveniently and quickly adjust the distance between the two ends of the sea tying rod and the equipment or the ship deck, and always keep it in a pre-tightened state. Moreover, this utility model is easy to assemble and disassemble, can be repeated and modularly used, and has the advantages of simple structure, high strength and low cost.

[0007] The objective of this utility model is achieved in the following manner:

[0008] An adjustable sea ties rod includes a sea ties rod body. Each end of the sea ties rod body has a tie rod hole. A pin is inserted into the tie rod hole, and both ends of the pin are threadedly connected to an eccentric sleeve. The eccentric sleeve is inserted into the tie rod hole and has a transition fit with it. Several bolt holes are provided on the sea ties rod body around the eccentric sleeve and the tie rod hole. Bolts pass through the eccentric sleeve to fix it to the end of the sea ties rod body around the tie rod hole.

[0009] The aforementioned adjustable sea tie rod also includes washers, and bolts pass through the washers and eccentric sleeves to fix the eccentric sleeves to the end of the sea tie rod body around the tie rod hole.

[0010] The aforementioned adjustable sea tie rod also includes a shaft end baffle. Bolts pass through the washer, shaft end baffle, and eccentric sleeve in sequence to fix the eccentric sleeve to the end of the sea tie rod body around the tie rod hole.

[0011] The aforementioned adjustable sea lashing rod has a lashing lug plate at the end of the lashing rod body, and a lashing hole is provided on the lashing lug plate.

[0012] The eccentricity of the eccentric sleeve in the aforementioned adjustable sea tie rod is 15mm.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] The following is combined with Figure 1-3 The specific implementation method of this utility model is described in detail.

[0026] An adjustable sea ties rod includes a sea ties rod body 11. The sea ties rod body 11 has tie rod holes 14 at both ends. A pin 10 is inserted into the tie rod hole 14, and both ends of the pin are threaded to an eccentric sleeve 12. The eccentric sleeve is inserted into the tie rod hole and has a transition fit with the tie rod hole. Several bolt holes are provided on the sea ties rod body around the eccentric sleeve and the tie rod hole. Bolts 7 pass through the eccentric sleeve to fix the eccentric sleeve to the end of the sea ties rod body around the tie rod hole.

[0027] The adjustable sea tie rod of this utility model also includes a washer 8 and a shaft end baffle 9. Bolts pass through the washer 8, the shaft end baffle 9 and the eccentric sleeve 12 in sequence to fix the eccentric sleeve to the end of the sea tie rod body around the tie rod hole.

[0028] The adjustable sea-binding tie rod of this utility model has a tie rod ear plate 15 at the end of the tie rod body. The tie rod ear plate has a tie rod hole 14. Bolts pass through washers 8, shaft end baffles 9 and eccentric sleeves 12 in sequence to fix the eccentric sleeve to the tie rod ear plate. When the tie rod is pre-tightened, the eccentric sleeve is rotated so that the bolt hole on the eccentric sleeve corresponds to the threaded hole on the tie rod ear. The two ends of the pin are clamped by baffles 9 and then fixed by bolts 7 and washers 8.

[0029] The adjustable sea rigging rod of this utility model has an eccentricity of 15mm for the eccentric sleeve. The maximum eccentricity of each end of the sea rigging rod of this utility model is 15mm, with a total eccentricity of 30mm at both ends.

[0030] The adjustment method of the adjustable sea tie rod of this utility model is as follows: Figure 1 and Figure 2 As shown, insert the nearest end of the eccentric sleeve 12 into the tie rod hole. Use internal threaded socket wrenches 13, suitable for eccentric sleeves, to grip the external threads of the eccentric sleeve 12 on both sides. Rotate it a certain angle to apply a preload to the tie rod. If the force is large, a hand chain hoist or crane can be used. After adjustment, install the shaft end plate and tighten the bolts. The user should perform the reverse steps when unloading at the site. During sea or river transport, the eccentric sleeve and pin must always be under stress for safety and reliability.

[0031] The following description uses a ship unloader as an example to illustrate the usage of this utility model. The entire weight of the ship unloader rests on the lower crossbeam of the gantry. The lower crossbeam consists of multiple sets of balance beams, trolleys, and wheel sets. Because the wheel sets roll, and they need to be rolled onto the ship during loading and unloading, they cannot be removed. Therefore, the degree of freedom of the lower crossbeam must be controlled to ensure that the entire equipment is integrated with the ship's structure to resist the impact of wind and waves during transportation.

[0032] 1. Lower crossbeam 2. Lower crossbeam lug 3. Adjustable sea lashing rod 4. Deck lug 5. Transport ship 6. Operating mechanism

[0033] like Figure 3 As shown, several sea lash lugs 2 are pre-designed and installed on the side web or bottom plate of the lower crossbeam 1. These, together with the adjustable sea lash rods 3 and the deck lugs 4 of this utility model, form a sea lash rod assembly. Each sea lash rod assembly controls the operating mechanism 6 placed on the hull 5, preventing the operating mechanism from moving in sea (river) transport, thereby controlling the degree of freedom of the lower operating mechanism of the whole machine and safely reaching the designated port.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
