Abstract
Description
Technical Field
[0001] The invention relates to the hoisting and installation of cargo shore connectors and cargo hoses in filling station areas of LNG carriers, LPG carriers and new fuel powered ships, and in particular to a detachable portable crane for a liquid cargo ship filling station. Background Art
[0002] At present, with the increase of new energy ships, for LNG liquid cargo ships, LPG transport ships and new fuel powered ships, liquid phase pipes and gas phase pipes are usually installed at the filling stations. Some transport ships are equipped with three pipelines of liquid phase pipe, gas phase pipe and liquid phase pipe or even more cargo handling pipelines for the convenience of transportation. When transporting cargo from ship to shore, ship to ship and ship to car, it is necessary to configure shore connectors of different specifications and use liquid cargo hoses for connection. Since these shore connectors and hoses are heavy and difficult for crew to carry, they need to be connected and installed with the assistance of cranes. Since the filling station is located in a dangerous area, the configured lifting equipment needs to meet the explosion-proof requirements, which is costly and difficult to arrange. Therefore, at the filling station, considering the use of mobile portable cranes is the best way to solve the installation of shore connectors and hoses. Regardless of the number of liquid phase pipes and gas phase pipes, only one side provides a mobile hose crane to ensure the convenient connection of the cargo shore connector and hose. When cargo needs to be refueled on the other side of the ship, it is only necessary to move the portable boom to the corresponding position for operation. Summary of the invention
[0003] The purpose of the present invention is to provide a detachable portable crane for a filling station of a liquid cargo ship which has a compact structure, convenient arrangement, flexible operation, and is safe and reliable.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a detachable portable crane for a filling station of a liquid cargo ship, comprising a cylindrical lifting rod (1), an I-shaped lifting beam (2), a portable lifting lug (4), a rotating handle (6), a movable lifting lug (7), a portable lifting base (8), a fixing pin (10), a portable lifting support column (12), a portable lifting upper support fixing ring (13) and a portable lifting upper support movable ring (14), wherein one end of the cylindrical lifting rod (1) is fixedly connected to the portable lifting base (8), and the other end is fixedly connected to the I-shaped lifting beam (2), the portable lifting base (8) is fixed on the deck, and the portable lifting base (8) is fixedly connected to the I-shaped lifting beam (2). The portable lifting lug (4) and the movable lifting lug (7) are respectively fixed on the I-shaped lifting beam (2); the rotating handle (6) is symmetrically mounted on the cylindrical lifting rod (1); the portable lifting support column (12) is connected to the cylindrical lifting rod (1) via a fixing pin (10), a portable lifting upper support fixing ring (13) and a portable lifting upper support movable ring (14); the portable lifting upper support movable ring (14) is fixed to the portable lifting upper support fixing ring (13) via bolts; a gap is left between the portable lifting upper support movable ring (14) and the cylindrical lifting rod (1) to ensure that the portable lifting can rotate 360°.
[0005] A beam bracket (3) is installed between the cylindrical suspension rod (1) and the I-shaped suspension beam (2).
[0006] A lifting eye reinforcement blocking plate (5) is installed between the I-shaped lifting beam (2) and the portable lifting eye (4).
[0007] A portable hanging base reinforcing bracket (9) is installed between the portable hanging base (8) and the deck.
[0008] Two lifting points are arranged on the portable lifting lug (4).
[0009] A water flow hole is arranged at the bottom of the portable hanging base (8).
[0010] The portable hanging support column (12) is provided with a rope (11).
[0011] The present invention discloses a detachable portable crane for a filling station of a liquid cargo ship, which meets the explosion-proof requirements of liquid cargo ships. According to the size of the filling station of the liquid cargo ship, a plurality of portable crane position points can be set. The portable crane is convenient to move and flexible to operate. The portable crane is the best way to solve the installation of shore connectors and hoses. No matter how many liquid phase pipes and gas phase pipes there are, convenient connection of the cargo shore connector and the hose can be ensured by providing a mobile hose crane on only one side. When cargo needs to be filled on the other side of the ship, the portable crane only needs to be moved to the corresponding position for operation. BRIEF DESCRIPTION OF THE DRAWINGS
