Description

Technical Field

[0001] This utility model relates to the field of shipbuilding fixture technology, and in particular to a positioning fixture for the oil tanker frame oil top. Background Technology

[0002] Aframax tankers, as economical tankers for short-haul transportation, typically have a deadweight tonnage between 80,000 and 120,000 tons, offering high economic efficiency and flexibility. Currently, the mainstream ship type on the market has a length exceeding 240 meters. The main hull of an Aframax tanker consists of a watertight outer shell composed of decks and outer plating, internally divided into numerous compartments by decks, longitudinal and transverse bulkheads, and their framework. The main hull forms the foundation of the superstructure, typically housing the engine room, fuel tanks, water tanks, and cargo holds. The main function of the main hull is to contribute to overall longitudinal strength, ensuring the hull's buoyancy and providing sufficient strength. The main hull is a long box-shaped structure composed of steel plates and a framework. The framework types can be categorized as longitudinal framework, transverse framework, and mixed framework. Longitudinal frameworks have denser longitudinal skeletons with smaller dimensions, while transverse skeletons are sparser and larger in size. The advantage of a longitudinal framework structure is better overall longitudinal strength. Due to the denser longitudinal skeleton arrangement, the plates have better stability, allowing for reduced plate thickness and structural weight. Longitudinal frame structures are widely used in the decks and bottoms of medium and large ships, as well as in the midsection of some oil tankers.

[0003] In existing longitudinal frame systems, the welding of longitudinal ribs and ribs involves first welding a baffle plate to position the hydraulic jack, then installing the jack and using it to push the longitudinal ribs. This adjusts the gaps between the web and face plates of the longitudinal ribs and the through holes in the ribs, as well as the gaps between the longitudinal ribs themselves, thus aligning the ribs and ribs to the appropriate welding positions. However, this method of welding the baffle plate requires welding, cleaning, and grinding, which increases workload and slows down positioning, thereby reducing construction efficiency.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown, the rib plate 41 has several longitudinal bone through holes 411 for the longitudinal bone 42 to pass through. Each longitudinal bone through hole 411 includes an upper hole 412 and a lower hole 413, the centerlines of which form a "7" shape to mate with the longitudinal bone 42. The longitudinal bone 42 includes an upper face plate 421 and a lower web plate 422, which form a "T" shape. The face plate 421 corresponds to and mates with the upper hole 412, and the web plate 422 corresponds to and mates with the lower hole 413. The gap between the lower surface of the face plate 421 and the lower edge of the upper hole 412 must meet assembly requirements; that is, the gap between the lower edge of the rib plate 41 and the inner bottom plate 43 must meet assembly and welding requirements; the gap between the side surface of the web plate 422 and the side edge of the lower hole 413 must meet assembly and welding requirements. When the existing rib plate 41 is installed on the longitudinal bone 42 by the pull-in method, the machining error of the longitudinal bone through hole 411, the machining error of the longitudinal bone 42 and the welding error will affect the passage of several longitudinal bones 42 through the corresponding longitudinal bone through hole 411 and the gap between the longitudinal bone 42 and the longitudinal bone through hole 411 after passing through.

[0021] A positioning fixture for the oil tanker frame top, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a connecting part 1 and a positioning part 2. The connecting part 1 is used to hook onto the edge of the longitudinal bone through hole 411 of the rib plate 41, and the positioning part 2 connects to the connecting part 1 and is used to position the hydraulic cap 5. In this application, the connecting part 1 hooks onto the edge of the longitudinal bone through hole 411 of the rib plate 41, the positioning part 2 positions the hydraulic cap 5, the base of the hydraulic cap 5 acts on the positioning part 2, and the piston of the hydraulic cap 5 acts on the longitudinal bone 42. The force is applied to the longitudinal bone through hole 411 of the rib plate 41 through the connecting part 1, thereby realizing the positioning of the hydraulic cap 5 and the transmission of force. This allows for convenient and quick adjustment of the relative position of the longitudinal bone 42 and the rib plate 41 through the hydraulic cap 5. This application can reduce workload, increase positioning speed, and thus improve construction efficiency.

[0022] Preferably, the connecting part 1 includes a connecting groove 11, and the edge of the longitudinal bone through hole 411 can be inserted into the connecting groove 11, thereby enabling the positioning fixture to be installed on the rib plate 41. When the oil top 5 extends and applies force to the positioning part 2, the connecting groove 11 is stably engaged with the edge of the longitudinal bone through hole 411, so that the relative position of the longitudinal bone 42 and the rib plate 41 changes to achieve gap adjustment.

[0023] Preferably, the positioning part 2 includes a positioning surface 21, the oil cap 5 is placed on the positioning surface 21, and the positioning surface 21 supports the base of the oil cap 5 to withstand the force.

[0024] Preferably, the positioning part 2 is connected to the connecting part 1 via the transition section 3 to accommodate the length of the oil cap 5.

[0025] Preferably, the positioning part 2 and the connecting part 1 are located on both sides of the transition section 3. When the connecting part 1 is hooked on the edge of the longitudinal bone through hole 411, the transition section 3 is attached to the rib plate 41. The positioning part 2 is located on the side of the transition section 3 away from the rib plate 41, which facilitates the installation of the oil cap 5 and the adjustment of the position of the oil cap 5.

[0026] Specifically, the connecting part 1 is made of a "U"-shaped steel rod, the positioning part 2 and the transition section 3 are made of steel rods, the positioning part 2 is perpendicular to the transition section 3, one end of the transition section 3 is fixedly connected to one end of the "U"-shaped opening of the connecting part 1, and the other end is fixedly connected to the end of the connecting part 1, and the other end of the positioning part 2 extends into the transition section 3 away from the connecting part 1 as a free end. The "U"-shaped groove of the connecting part 1 is a connecting groove 11, and the surface of the positioning part 2 facing the connecting part 1 is a positioning surface 21.

[0027] Specifically, the connecting part 1, the transition section 3, and the positioning part 2 are integrally formed.

[0028] The working principle of the device in this application is as follows:

[0029] When it is necessary to adjust the gap between the lower surface of panel 421 and the lower edge of upper hole 412:

[0030] The connecting groove 11 is snapped onto the lower edge of the upper hole 412. The positioning fixture is set vertically, the transition section 3 abuts against the surface of the rib plate 41, and the positioning part 2 extends outward perpendicular to the surface of the rib plate 41.
