Problems solved by technology

The installation of the slide plate and slide rail is troublesome; long-term sliding friction will cause damage to the slide plate and slide rail to a certain extent, and at the same time it will inevitably increase the working load of the mobile power pump unit; in order to reduce the sliding friction force, a large amount of lubrication is required Grease; in addition, there are many operating procedures, resulting in low efficiency of the crew

Embodiment Construction

[0021] A kind of semi-submersible floating tank mobile device, such as figure 1 , including two side-by-side parallel guide rails 2 arranged on the deck 1 surface, two guide rails are provided with a plurality of positioning holes 7 in the same position as fixed positions, each guide rail is equipped with a stretching oil cylinder 4, each pull One end of the oil extension cylinder is fixed with a fixed seat 3, which is stuck on the guide rail, and a fixed hole corresponding to the positioning hole is provided at the bottom of the fixed seat, and the fixed seat can be locked on the guide rail by bolts and nuts. It is fixedly connected with the tie plate 6 provided at the bottom of the buoyancy tank, and can be connected with the tie plate through bolts and nuts, or can be directly welded on the tie plate. A plurality of rolling devices 5 are arranged at intervals on each guide rail; the rolling devices can be fixed on the guide rail, and can rotate relative to the guide rail, a...

Abstract

The invention discloses a device and a method for moving a buoyancy tank of a semi-submersible ship. The device comprises a plurality of parallel guide rails which are arranged side by side on a the surface of a deck and provided with a plurality of corresponding fixing positions, and each guide rail can be detachably fixed at one fixing position by a fixing seat; each guide rail is provided with a stretching oil tank, one end of the stretching oil tank is fixed on the guide rail by the fixing seat, and the other end of the stretching oil tank is fixedly connected with a pulling plate arranged at the bottom of a buoyancy tank; and each guide rail is provided with a plurality of rolling devices which are arranged at intervals. when the buoyancy tank is moved, the buoyancy tank is put on the guide rails by the rolling devices, therefore, the buoyancy tank can be moved with a small pulling force just by overcoming the rolling friction, and the stretching oil tank can be pulled easily; therefore, the device has the advantages of low power consumption and high efficiency and is simple and convenient to operate.

Description

technical field [0001] The invention relates to a device on a semi-submersible ship for moving a large pontoon with a high center of gravity and a large weight, and a method for moving the pontoon using the device. Background technique [0002] The stern of a semi-submersible ship is usually equipped with a large pontoon with a high center of gravity, large volume, and heavy weight to adjust and control the stability and buoyancy of the ship. When loading cargo, semi-submersible ships sometimes need to adjust the position of the buoy due to the limitations of the specific conditions of the cargo, such as moving from the stern of the ship to the bow, or from the left to the right. After unloading the goods, it needs to return to its position. [0003] At present, there are mainly two methods for moving the pontoon. Firstly, guide rolling devices are set on the bow wall and the deck surface, and the cargo winch on the top of the buoyant box is used to pull the buoyant box pl...
