Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a pipe-hanging installation tool used for the hanging and installation of latch-type pile legs and piles. Background Art

[0002] In the manufacture of self-elevating wind turbine installation vessels and the construction of offshore platforms, it is necessary to hoist and install pile legs. The pile legs are a very critical component of the self-elevating wind turbine installation vessel, used to support the weight of the upper hull and withstand environmental conditions such as wind, waves, and currents. The structure is mainly cylindrical. In order to lift the pile legs, many pin holes are opened on the pile legs. Existing technologies, such as the invention patent with publication number CN104805858B, disclose a self-elevating platform pile leg and an offshore platform having the pile leg.

[0003] The usual procedure is to use wire ropes and large shackles to tie and fix the pile leg segments or the entire segment, and then use a crane and wire rope to lift and remove the tires. Then, use the lifting chain or wire rope to readjust the fixing method to turn over and install the pile leg segments or the entire segment for lifting. During traditional lifting, the rigging (usually the lifting wire rope) is often connected to the pile leg segment through the pile leg pin hole. During this process, the contact surface between the rigging and the segment is only the thickness of the pile leg, but the shear force on the rigging is the weight of the entire pile leg. The huge shear stress causes a large loss of the lifting rigging and is prone to safety accidents. Therefore, according to safety requirements, the wire rope used in traditional operations is generally scrapped after only one use. In actual operation, in order to improve safety, a lifting lug is welded to the end of the pile leg tube wall for lifting. After lifting, it needs to be manually cut, polished and inspected at high altitude to pass the inspection. Although it can ensure safety, the operation is cumbersome and time-consuming.

Then, move the limit plate, clamp the wire rope between the baffle and the limit plate, and fix the limit plate through the limit plate fixing assembly to prevent the wire rope from sliding on the extension tube during the lifting process. Then, the pile leg can be lifted, the contact area of ​​the wire rope is increased, and the safety is improved. After the lifting is completed, the extension tube and the lifting tube can be disassembled and recycled, which is easy to operate and improves the installation efficiency.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0031] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] See also Figures 1 and 2 When the lifting pole is lifted up, the lifting pole 1 is tightened, and the lifting pole 1 is tightened to the lifting pin 2, so that the lifting pole 1 is tightened.

When splicing the extension tube, the flange of the extension tube is aligned with the flange of the hanging tube, and then the bolts are passed through and the nuts are screwed in to complete the splicing and fixation of the extension tube and the hanging tube. When disassembling, the bolts and nuts can be removed.

[0035] See also Figures 1 to 5In some embodiments, the limit plate fixing assembly includes a sleeve 51 and a locking screw 52. The sleeve 51 is sleeved on the extension tube, and its side wall is fixed on the limit plate; the locking screw 52 is screwed on the sleeve, and a plurality of locking holes 21 for the locking screws to pass through are evenly opened on the extension tube. By rotating the locking screw into the locking hole, the limit plate can be fixed, which facilitates the adjustment of the position of the limit plate.

[0036] Preferably, a limiting protrusion 53 is fixed on the inner wall of the sleeve 51, and a sliding groove 22 is provided on the outer wall of the extension tube 2. The limiting protrusion can slide relative to the sliding groove, thereby limiting the rotation of the sleeve relative to the extension tube, making it easier for the locking screw to align with the locking hole.
