It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the drawings related to the present invention are shown.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixed or removable, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements.

In the process of long-distance large-tonnage transportation, the ship plays a very important role, and provides great convenience for people to travel and logistics transportation away from. Wherein the host is a very important power component on the vessel, the installation of the host on the hull is very important.
In the prior art, a host is installed on a host base, and the host installed in a steel gasket mode is currently configured by directly brushing a panel of the host base and the steel gasket on a construction site. Because of the processing error of the panel of the main machine base, when the main machine base is brushed on site, the work load of site polishing is large, the labor intensity is high, the working period is long, the installation period of the main machine is prolonged, and even the construction period of a ship is influenced.
In order to solve the above problems, the polishing workload can be reduced, the labor intensity can be reduced, the smooth polishing of the main frame panel and the steel gasket can be ensured, and the smooth installation of the main frame can be ensured, so that the construction period can be shortened, and the invention provides a method for polishing the main frame panel and the steel gasket of a ship, as shown in fig. 1. The method for brushing and matching the main engine base panel and the steel gasket of the ship comprises the following steps:
s1, finishing construction of a main engine base;
s2, carrying out plane milling operation on a frame web plate of the main frame;
s3, milling a plane of a frame panel of the main frame by taking a frame web as a reference plane;
s4, carrying out sectional large-assembly installation on the main engine base;
s5, transporting the installed sections of the main machine base to a construction site to be matched with the steel gasket in a brushing mode.
The plane milling processing is firstly carried out on the base web plate, and then the plane is used as a reference to carry out the plane milling processing on the base panel of the main base, so that the flatness of the base panel can be ensured to meet the requirement, and after the large-section assembly is completed, the base panel and the steel gasket are matched in a brushing way. By processing the frame panel of the main frame in advance, the polishing workload of the frame panel can be reduced, the labor intensity is reduced, smooth matching of the frame panel of the main frame and the steel gasket is ensured, and smooth installation of the main frame is ensured, so that the construction period is shortened.
Further, in step S1, the flatness deviation of the base panel of the built main foundation is not greater than the first set value. Specifically, in the present embodiment, the first set value is 4mm. The subsequent workload of milling the base panel can be reduced by controlling the flatness of the base panel of the built main base. In other embodiments, the first setting value may be set according to actual needs, and no limitation is made here.
Further, in step S1, the transverse bending deviation of the built main frame is not greater than the second set value. The transverse bending deviation of the main machine base is limited, so that the quality of the main machine base can be ensured to meet the requirements. In this embodiment, the second setting value is 2mm, and in other embodiments, the setting may be performed according to actual needs, and no excessive limitation is made here.
Further, in step S2, the main frame is placed on the reference platform to perform a plane milling operation on the frame web. Through setting up the benchmark platform, can guarantee to mill the plane operation to the frame web and go on smoothly, can guarantee moreover that planar planarization satisfies the requirement. Therefore, when the machine base panel is further processed, the processing flatness can be ensured to meet the requirement.
Further, in this embodiment, the machining allowance of the base web is controlled to be 0-8 mm, and in other embodiments, the setting of the machining allowance of the base web may be performed according to the field requirement and the type of the base web, which is not limited.
Further, in step S3, after finishing the processing of the base panel, the surface of the milled plane is coated with rust-proof oil and laid with three-proofing cloth for protection. Through protecting the surface of the milled plane, the anti-rust oil and the three-proofing cloth can prevent the plane milled by the machine base panel from being oxidized and rusted under the action of air, and simultaneously prevent the milled plane from being scratched. The three-proofing cloth has the effects of fire prevention, water prevention and corrosion prevention, and can effectively protect a milled plane.
Further, in step S4, the flatness of the frame panels of the main frames are measured wholly and locally before and after the welding in the large-section assembly, so that the overall flatness of the frame panels of a single main frame is less than or equal to 3mm, and the flatness of the frame panels of two main frames in the same group is less than or equal to 8mm. The flatness before and after welding is measured, whether the flatness meets the requirements can be determined, and the flatness of the base panel can be processed immediately if the flatness does not meet the requirements, so that the flatness of the base panel and the flatness of two base panels in the same group can meet the requirements before the base panel is lifted to be in a field to be matched with a steel gasket in a brushing mode.
Further, after the measurement is completed, the engine base panel is subjected to rust protection and covered by three-proofing cloth. Similarly, the rust preventive oil and the three-proofing cloth can prevent the plane milled by the machine base panel from being oxidized and rusted under the action of air, and simultaneously prevent the milled plane from being scratched. The three-proofing cloth has the effects of fire prevention, water prevention and corrosion prevention, and can effectively protect a milled plane, so that the flatness of the machine base panel can be ensured to always meet the requirements before the milling. And the damage to the frame panel of the main frame during the sectional sanding and coating can be prevented.
The lifting hanging code is arranged on the main machine seat to cause the deformation of the main machine seat, so that the flatness of the machine seat panel cannot meet the requirement. Thus, further, in step S5, the transported hoist bail cannot be arranged on the main foundation.
By carrying out primary plane milling processing on the engine base panel of the main engine base in advance, the on-site milling work amount of the main engine base in the existing operation mode is greatly reduced, the period required by installing the main engine is shortened, and the effect of shortening the ship building period is indirectly achieved.
The embodiment also provides a ship, which is built by adopting the method for matching the main engine base panel of the ship with the steel gasket, and the engine base panel of the main engine base is processed in advance, so that the labor intensity can be reduced during on-site matching, smooth matching of the engine base panel of the main engine base and the steel gasket is ensured, and smooth installation of the main engine is ensured, thereby shortening the building period.
It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are desired to be protected by the following claims.
