Description

Technical Field

[0001] The invention relates to the technical field of vertical wind turbine tower loading and unloading, and in particular to a loading and unloading process of a large-diameter vertical wind turbine tower. Background Art

[0002] Generally, large-diameter vertical wind turbine towers are loaded onto ships by hoisting with large lifting equipment. Since large-diameter vertical wind turbine towers are manufactured in the inner field, they need to be transported to the front of the dock and hoisted onto the ship with large lifting equipment. The transportation in the inner field and the hoisting at the dock must be carried out separately, which has low work efficiency. In addition, the vertical wind turbine towers are densely distributed on the deck of the ship. The traditional hoisting method of large lifting equipment has a greater risk of collision. In addition, the hoisting method requires a lot of time to position the vertical wind turbine tower on the deck. This loading process is inefficient and labor-intensive. Therefore, a new loading process for large-diameter vertical wind turbine towers is needed, which combines the infield transportation of large-diameter vertical wind turbine towers with the loading at the dock, and performs operations in an integrated manner to improve loading efficiency and shorten the time of operating ships in port. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a ship loading process for large-diameter vertical wind turbine towers, which can solve the problem of low efficiency and high safety risks in the traditional large-diameter vertical wind turbine tower loading method using a gantry crane.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a ship loading process of a large-diameter vertical wind turbine tower, and its innovation lies in: the specific ship loading process is as follows: S1: Installation of hull piers: on the deck of the hull, a placement area for the vertical wind turbine tower is marked according to the size of the vertical wind turbine tower, and a pier group for supporting the vertical wind turbine tower is arranged in the placement area of ​​each vertical wind turbine tower, and a number of pier units are arranged in each pier group; S2: Loading of vertical wind turbine tower: first, place the vertical wind turbine tower on a pair of parallel support beams, and arrange a clamping plate on the support beam to cooperate with the flange surface at the bottom end of the vertical wind turbine tower to fix the vertical wind turbine tower on the support beam; four hydraulic jacking vehicles are used, a front cross beam is connected to one pair of hydraulic jacking vehicles, and a rear cross beam is connected to the other pair of hydraulic jacking vehicles, and an ear plate is arranged on the lower surface of the front cross beam and connected to the front end of the support beam through a pin shaft, and an ear plate is arranged on the lower surface of the rear cross beam and connected to the rear end of the support beam through a pin shaft, and the support beam and the vertical wind turbine tower are lifted off the ground together by the jacking of the hydraulic jacking vehicle; S3: Vertical wind turbine tower on board: at least four hydraulic lifting vehicles move synchronously to move the vertical wind turbine tower fixed on the support beam to the placement area on the ship; the hydraulic lifting vehicles transport from the gaps between adjacent pier groups and the edges of the pier groups, and the support beams on the hydraulic lifting vehicles pass through the gaps between the pier units in each pier group, so that the vertical wind turbine tower is located above each pier unit; S4: Onboard support of vertical wind turbine tower: a load-bearing beam is arranged on the circumference of the pier group on the deck of the ship, and the front cross beam and the rear cross beam on the hydraulic lifting vehicle are supported by the load-bearing beam; the hydraulic lifting vehicle is lowered to place the vertical wind turbine tower on the surface of the pier unit, and then lowered again so that the front cross beam and the rear cross beam are supported on the load-bearing beam; S5: Fixing of vertical wind turbine tower: Connect and lock the flange at the bottom of the vertical wind turbine tower with the pier unit through the locking structure, and fix the inside and outside of the bottom of the vertical wind turbine tower, then remove the clamping plate connecting the vertical wind turbine tower and the support beam; weld the reinforcing rib plate between the outer side of the pier unit and the deck of the ship; then fix the vertical wind turbine tower with a cable wind rope; S6: Disembarkation of the hydraulic jacking vehicle: The hydraulic jacking vehicle needs to be dismantled and disembarked; the front beam and rear beam of the hydraulic jacking vehicle are located on both sides of the vertical wind turbine tower. After the vertical wind turbine tower is placed, the rear beam on the hydraulic jacking vehicle needs to be removed from the hydraulic jacking vehicle and supported on the load-bearing beam; the hydraulic jacking vehicle and the front beam return along the original route of embarkation, and the rear beam needs to be lifted from the ship by a crane on the shore and disembarked for the transportation of the next vertical wind turbine tower; S7: All vertical wind turbine towers are loaded onto the ship: Steps S2 to S6 are repeated to load all vertical wind turbine towers onto the ship.

[0005] Furthermore, in the above S3: when the vertical wind turbine tower is loaded onto the ship, it is necessary to inspect the area that the hydraulic lifting and transporting vehicle on the ship passes through to ensure that the walking route area is flat and navigable.

[0006] Furthermore, the vertical wind turbine tower is loaded from the bow to the stern, and from the area far from the shore to the area close to the shore.

[0007] The advantages of the present invention are: 1) In the present invention, a vertical wind turbine tower is transported onto a ship by using a hydraulic lifting vehicle, and a front crossbeam and a rear crossbeam are connected to a support beam on which the vertical wind turbine tower is placed, and the vertical wind turbine tower is lifted up by the hydraulic lifting vehicle; this method reduces the time spent on hoisting the vertical wind turbine tower and reduces the labor intensity; after the vertical wind turbine tower is on board, auxiliary tools are used to fix it on the pier unit; due to the obstruction of the pier unit, the rear crossbeam structure of the hydraulic lifting vehicle is installed on the hydraulic lifting vehicle by hoisting off the ship; this method greatly improves the efficiency and safety of loading the vertical wind turbine tower.
