[0002] The pump tower is an important functional component in the cargo hold area of an LNG ship. Its structure is in the shape of a triangular mast and is vertically suspended in each cargo hold, undertaking the function of loading and unloading liquid natural gas.

[0003] The existing LNG ship pump tower has a large overall structure and a large overall weight. When installing the LNG ship pump tower, the whole LNG ship pump tower is lifted to a designated position by a tower crane, and the LNG ship pump tower is dropped into the LNG ship through a hole set on the ship deck. The bottom of the LNG ship pump tower needs to fall into a designated connecting piece. However, due to the large weight and size of the LNG ship pump tower, and the tower crane needs to operate at a relatively far position, it is difficult to connect the bottom of the LNG ship pump tower with the connecting piece inside the LNG ship. Nowadays, through the synchronous communication between the staff on the deck, the staff inside the ship, and the crane operator, and the staff inside the LNG ship continuously adjusts the position by using ropes, it is difficult to ensure the installation accuracy, which is time-consuming and laborious.

[0004] Therefore, the utility model provides an LNG ship pump tower to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-4 , an LNG ship pump tower, including an emergency pipe 1, a support pipe 4 is fixedly connected to the outside of the emergency pipe 1, a discharge pipe 2 is fixedly connected to the end of the support pipe 4 away from the emergency pipe 1, the emergency pipe 1 is fixedly connected to a liquid filling pipe 3 through a connecting block, and is characterized in that it further includes an installation auxiliary mechanism, and the installation auxiliary mechanism includes a moving ball 595.

[0025] Installation rings 51 are provided on the outside of both the emergency pipe 1 and the discharge pipe 2. Two second threaded holes 55 are provided on the installation ring 51. The inner side of the second threaded hole 55 is threadedly connected to a first threaded rod. Two third threaded holes 596 are provided on the installation ring 51.

[0026] The installation auxiliary mechanism further includes a fixed block 52. A first threaded hole 54 is provided on the fixed block 52. The fixed block 52 is fitted with the installation ring 51. The first threaded hole 54 and the third threaded hole 596 are internally threadedly connected to a second threaded rod. Electric hydraulic push-pull rods 53 are provided on both sides of the fixed block 52.

[0027] The front end of the electric hydraulic push-pull rod 53 is fixedly connected to a connecting plate 57. The side end of the connecting plate 57 is fixedly connected to a clamping plate 58. A round rod 56 is movably connected to the inner side of the clamping plate 58.

[0028] A rotating pipe 59 is rotatably connected to the outside of the round rod 56. A handle 591 is fixedly connected to the outside of the rotating pipe 59. Four electric jacks 592 are provided on the outside of the round rod 56. An outer fixed ring 593 is fixedly connected to the outside of the electric jack 592. The moving ball 595 is arranged at the bottom end of the round rod 56.

[0029] The bottom end of the electric jack 592 is fixedly connected to a support plate 594.

[0030] Working process: Through the first threaded rod and the second threaded rod, the mounting ring 51 is fixed to the outer sides of the emergency pipe 1 and the unloading pipe 2 respectively. By adjusting the telescopic movement of the electric hydraulic push-pull rod 53, the connecting plate 57 is driven to move in the direction close to or away from the mounting ring 51, so that the movement of the connecting plate 57 drives the clamping plate 58 to clamp or release the round rod 56. The LNG ship pump tower is lifted by the tower crane to the specified height, and the handle 591 is manually operated to push the round rod 56. The round rod 56 is moved to the previously calculated specified position through the moving ball 595. Then, by positioning the positions of the three round rods 56, the LNG ship pump tower is adjusted to a suitable angle, facilitating the subsequent placement of the LNG ship pump tower and connection with the internal connectors of the LNG ship. When the round rod 56 moves to the specified position, the electric jack 592 is extended so that the support plate 594 abuts against the internal floor of the LNG ship. Then, the electric hydraulic push-pull rod 53 is adjusted to release the round rod 56, and the LNG ship pump tower is slowly placed down through the tower crane, so that the round rod 56 moves upward relative to the fixed block 52 until the LNG ship pump tower is placed at the bottom inside the LNG ship and is quickly connected to the internal connectors of the LNG ship.

[0031] After placing the LNG ship pump tower, by disassembling the first threaded rod and the second threaded rod, it is convenient for overall disassembly and avoids affecting the subsequent use of the LNG ship pump tower.
